Description

Technical Field

[0001] This invention relates to the field of continuous beam casting construction technology, and in particular to a method for cantilever casting of continuous beams. Background Technology

[0002] Cantilevered continuous beams are often constructed in challenging terrains such as those crossing roads, rivers, and mountainous areas. They are typically constructed using hanging basket cantilever formwork. While this method has been developed for over 70 years and is a mature and stable technology, its construction cycle is difficult to reduce; the construction period for a single continuous beam segment is generally around 10 days. In railway and highway engineering projects, large-span continuous beams often consist of multiple segments, making hanging basket construction increasingly a key constraint on project timelines. Under pressure to shorten project timelines, the traditional cantilever hanging basket construction method faces significant challenges.

[0003] All cantilever construction is essentially defined as high-altitude work. Using hanging formwork in continuous beam construction presents limited space, and the segmental formwork skeleton occupies a significant amount of space. The confined space and dense equipment create high operational risks. For example, in rebar cage assembly, rebar work typically follows formwork adjustment. Due to limitations in personnel and machinery, rebar work often relies on workers assembling individual bars on-site. Compared to centralized formwork processing, this piece-by-piece assembly presents numerous problems, including longer construction cycles, lower positioning accuracy, greater operational difficulty, and challenges in ensuring welding quality. Furthermore, hanging formwork construction suffers from high reliance on manual labor, discontinuous operations, and low efficiency. For instance, in outer formwork construction, the outer formwork typically uses a steel panel and steel rib truss support structure. Under low deformation conditions, it is often reused multiple times. During construction, the outer formwork support and sliding are usually achieved using sufficiently long steel sections as guide beams. These guide beams are supported by upper and lower slings pulling the lifting rings. The current support consists of a front lifting ring pinned to the guide beam and a rear lifting ring slidably connected to the guide beam. With the cooperation of the front and rear lifting rings, the guide beam moves forward synchronously with the outer formwork flange template support truss, simultaneously bearing the weight of the outer formwork under no-load movement and pouring construction loads. The outer formwork flange template support truss moves forward via a track sliding method, relying on the traction of step jacks. This involves a large workload and is highly dependent on operator skills, resulting in poor continuity of segmental forward movement, long overall operation time, and high requirements for operator proficiency. Furthermore, during the moving operation, the conversion lifting rings must be slid forward manually to facilitate the conversion of the hanging support, which carries the risk of slippage and poses a significant operational risk. Finally, after the outer formwork has slid into place, the top elevation needs to be adjusted according to the design drawings. This adjustment is achieved using manual screw jacks, a slow and high-altitude risk method.

[0004] Researching the cantilever casting method for continuous beams is of great significance in order to reduce the risks of high-altitude operations, improve the continuity of construction operations, improve construction quality, and shorten the operation time. Summary of the Invention

The cantilever casting machine moves to the front of the construction site, assembles the bottom formwork and outer formwork on the bottom load-bearing mechanism, hoists the prefabricated steel cage onto the bottom formwork and between the outer formwork, assembles the inner formwork, and pours concrete after the formwork device is installed.

[0010] S3. After the concrete has solidified and reached a certain strength, the bottom formwork, outer formwork, and inner formwork are detached from the poured continuous beam segment. The outer formwork and bottom formwork follow the cantilever casting machine to the front end of the next casting segment. The height and level of the outer formwork and the elevation angle and height of the bottom formwork are adjusted. Then, the prefabricated steel cage is hoisted onto the bottom formwork and between the outer formwork. The inner formwork is moved to the matching duct position in the middle of the steel cage.

Next, disconnecting the connection between the adjusting section side plate unit and the bottom side plate unit; lifting the adjusting section side plate unit away; and hoisting the reduced-height adjusting section side plate unit to the replacement position. Finally, connecting the newly replaced adjusting section side plate unit to the bottom side plate unit; extending the left and right telescopic components connected to the top support outwards; and connecting the bottom... Adjust the angle of the left and right telescopic components connected to the side plate unit upwards and / or adjust the height of the support gantry to make the newly replaced adjusting section side plate unit fit snugly with the top side plate unit, thus completing the connection and fixation between the newly replaced adjusting section side plate unit and the top side plate unit. Adjust the angle and height of the bottom load-bearing mechanism and the height of the support gantry. Retract the angle adjustment component at the rear end of the bottom support longitudinal beam to match the elevation angle and height of the bottom formwork with the elevation angle and height of the designed beam segment bottom plate, and restore the support gantry to a vertical state. Match the angle and height of the outer formwork flange template with the position of the designed beam segment flange plate, thus completing the replacement and closing of the outer formwork.

[0020] Furthermore, the inner mold includes an inner mold top plate, inner mold side plates, and an inner mold support truss. The inner mold top plate is provided with inner mold side plates on both sides, and the inner mold support truss is provided at intervals below. The inner mold lateral telescopic rod is fixedly provided in the support truss. The width of the inner mold support truss can be adjusted by the inner mold lateral telescopic rod, so as to adjust the width of the inner mold.

[0022] The process of moving the inner formwork to the matching duct position in the middle of the reinforcing cage specifically includes: retracting the upper and lower chamfered expansion joints to shorten the height of the inner formwork support gantry, so that the inner formwork support gantry is in a state where the inner formwork suspension components are suspended; in the suspended state, pushing the inner formwork support gantry forward so that the inner formwork traveling mechanism can be located on the front of the inner formwork support gantry; part of the inner formwork support gantry is set at the bottom of the already poured continuous beam duct, and the other part is erected on the reinforcing cage; adjusting the inner formwork support gantry to a suitable height so that the inner formwork traveling mechanism can abut against the inner formwork support truss; adjusting the width of the inner formwork top plate and the inner formwork support truss; the inner formwork traveling mechanism drives the inner formwork forward to the designed position; the upper and lower chamfered expansion joints extend; and the inner formwork is fixed to the outer formwork by tie rods.

[0035] The above-described continuous beam cantilever casting method has the following advantages:

[0036] (1) Through the pouring method of the present invention, the construction of the outer formwork is changed from the complicated process of simple support and hanging to the construction method of direct support at the bottom. The outer formwork moves forward directly with the cantilever pouring machine, which greatly improves the continuity of the operation, reduces the risk of high-altitude operation, improves the construction efficiency, and reduces the dependence on the skill level of manual operation.

[0037] (2) The casting method of the present invention can realize the overall hoisting of the steel cage, which replaces the method of directly assembling the steel cage on the segment template, solves the problem of uneven tilting of the skeleton or components, significantly improves the quality level of the steel cage, and the pre-processing of the steel cage directly breaks the fixed time of the traditional hanging basket process, thereby reducing the construction time of a single beam segment and accelerating the progress of cantilever construction.

[0038] (3) By using the casting method of the present invention, the inner mold can be moved forward as a whole through the cooperation of the inner mold traveling mechanism and the inner mold support gantry, which changes the problem of discontinuous operation and low operation efficiency of the traditional guide beam and lifting ring cooperation to move the inner mold forward, effectively improving construction efficiency and shortening construction time.

[0039] (4) The present invention enables automated installation and disassembly of side molds and inner molds, replacing the traditional manual hoisting and manual installation and disassembly of templates. This effectively reduces the intensity and difficulty of manual labor, lowers the risk of high-altitude operations, and improves construction efficiency. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

They are only used to facilitate the description of this invention and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0068] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0069] A method for cantilever casting of continuous beams, combined with Figure 1-3 As shown, the process includes the following steps: S1. Installing the cantilever casting machine, which includes a support frame system, a walking system under the support frame system, a suspension mechanism at the front end, and a bottom load-bearing mechanism connected to the lower end of the suspension mechanism to support the formwork device, the reinforcing cage 18, and the continuous beam 26 segments being cast. The formwork device includes a bottom formwork 46, an outer formwork, and an inner formwork; S2. The cantilever casting machine moves to the construction front end, assembling the bottom formwork 46 and outer formwork on the bottom supporting structure. The prefabricated steel cage 18 is hoisted onto the bottom formwork 46 and between the outer formwork, and the inner formwork is assembled. After the formwork device is installed, concrete is poured. S3. After the concrete has solidified and reached a certain strength, the bottom formwork 46, outer formwork, and inner formwork are detached from the already poured continuous beam 26 segment. The outer formwork and bottom formwork 46 follow the cantilever casting machine to the construction front end of the next pouring segment. The height and level of the outer formwork and the elevation angle and height of the bottom formwork 46 are adjusted. The prefabricated steel cage 18 is then hoisted onto the bottom formwork 46 and between the outer formwork. The inner formwork is moved to the matching duct position in the middle of the steel cage 18. After the formwork device is installed, concrete is poured. Step S3 is repeated until the continuous beam 26 is poured.

[0070] The following describes the support frame system and walking system of the cantilever casting machine: This embodiment provides a specific example of a support frame system, including columns 14, a lower walking beam 7, an upper load-bearing beam 15, and a transverse connecting structure. Two columns 14, one lower walking beam 7, and one upper load-bearing beam 15 form a support truss. Specifically, the columns 14 are arranged vertically and parallel, with their upper ends connected to the upper load-bearing beam 15 and their lower ends connected to the lower walking beam 7. A portion of the upper load-bearing beam 15 and a portion of the lower walking beam 7, together with the columns 14, form a support truss. The trusses are connected by a transverse connecting structure. The supporting trusses are square. This transverse connecting structure can connect between the columns 14, and / or between the upper load-bearing beams 15, and / or between the lower traveling beams 7. It is sufficient to fix the two supporting trusses into a whole. Since the front end of the supporting frame system experiences greater pressure on the hoisted steel cage, preferably, an upper front transverse beam 16 is connected to the front end of the two upper load-bearing beams 15, and a lower rear transverse beam 29 is also connected to the lower front of the two front-side columns 14 to better ensure the stability of the front side of the supporting frame system. To ensure the stability and support strength of the supporting frame system, detachable frame diagonal braces 8 and / or frame longitudinal beams are provided in the supporting truss formed by the columns 14, lower traveling beams 7, and upper load-bearing beams 15, connecting the two columns 14. This embodiment... Figure 2 The diagram shows a preferred embodiment where a longitudinal frame beam connects the middle sections of the columns 14, and diagonal braces 8 connect the top of the columns 14 to the middle of the longitudinal frame beam, and the bottom of the columns 14 to the middle of the longitudinal frame beam. To prevent the reinforcing cage 18 from being obstructed by the support frame system during hoisting and lowering, the middle section of the upper load-bearing beam 15 is connected to the upper end of the front column 14, meaning the front end of the upper load-bearing beam 15 extends beyond the front column 14. To ensure the support strength and stability of the upper load-bearing beam 15, detachable diagonal braces 8 can also be connected between the front end of the upper load-bearing beam 15 and the front column 14. To ensure the balance of the entire support frame system, an extension section of the lower traveling beam 7 can be connected to the rear end of the lower traveling beam 7. The extension section of the lower traveling beam and the lower traveling beam 7 can be anchored together with bolts, i.e., as shown... Figure 3 The structure shown has a detachable frame brace 8 connecting the extended section of the lower traveling beam to the rear column 14. For any detachable connection in the support frame system, bolt connections can be used for easy assembly and disassembly.

[0071] Combination Figure 2 As shown, during the continuous beam pouring, two cantilever pouring machines can be installed simultaneously on block 0 of the continuous beam, facing the direction of block 1 respectively. The lower traveling beams 7 of the two cantilever pouring machines are connected together. After the construction of block 1 is completed, the connection between the two cantilever pouring machines is removed. After moving forward a certain distance, the extension section of the lower traveling beam is connected to the rear end of the lower traveling beam 7, and the frame diagonal bracing 8 is installed. At the same time, the construction of block 2 begins to save construction time.

[0072] For the walking system, a structure capable of moving the entire cantilever casting machine is sufficient, such as multiple rolling wheels. This embodiment also provides a preferred structure, combined with... Figure 5-7 As shown, the rolling wheel assembly structure 6 includes a travel drive motor 601, a gearbox 602, a drive wheel 603, a driven wheel 604, and a protective steel frame 606. The travel drive motor 601 is mounted on the protective steel frame 606, which provides support for the travel drive motor 601. The travel drive motor 601 provides power for the rotation of the gearbox 602. The gearbox 602 drives the drive wheel 603 to rotate through a transmission component, and the drive wheel 603 drives the driven wheel 604 to rotate through a transmission component. The transmission component can be a belt or a sprocket, depending on the actual situation. The gearbox 602 can be a gear or sprocket structure with a smaller radius than the drive wheel 603, thereby realizing the speed change function. The driving wheel 603 and driven wheel 604 have the same radius and are housed within the protective steel frame 606, connected to it via bearings. The protective steel frame 606 can be square, maintaining a certain gap with the traveling track mechanism. It provides protection for the driving wheel 603 and driven wheel 604, and supports the bearings connected to the shafts of the driving wheel 603 and driven wheel 604. The driving wheel 603 and driven wheel 604 can travel on the traveling track mechanism. The protective steel frame 606 is rotatably connected to the lower traveling beam 7. The number of rolling wheel sets 6 for each traveling support mechanism 6 can be selected as needed. The preferred structure of the rolling wheel sets 6 ensures support for the support frame system and guarantees the stability of movement. More preferably, the protective steel frame 606 is provided with a protective steel frame fork lug 605, and the lower traveling beam 7 is provided with a traveling mechanism fork lug 44. The protective steel frame fork lug 605 and the traveling mechanism fork lug 44 are connected by a pin. This pin connection method allows the pin connection to adjust its angle adaptively during the forward movement of the hoisting device or when there is a slight forward tilt during hoisting operations, preventing the traveling wheel assembly located at the rear of the device from derailing.

[0073] To ensure the all-in-one machine travels along a predetermined route, the traveling system also includes a traveling track 20 and beam support pads 21. The traveling track 20 includes tracks and track connecting beams. The beam support pads 21 are spaced parallel to each other and laid along the moving direction of the rolling wheel assembly structure 6. Two tracks are provided, parallel to each other and perpendicular to the beam support pads 21. The tracks are connected at intervals by track connecting beams, which connect the tracks into a single unit. Since the surface of the continuous beam 26 may be uneven, the beam support pads 21 maintain the flatness of the traveling track 20. The traveling track 20 provides the track for the rolling wheel assembly structure 6 to travel on. In this embodiment, combined with... Figure 7As shown, four sets of rolling wheel structures 6 are matched under a lower traveling beam 7. Each pair of sets is parallel to each other to maintain the balance of the lower traveling beam 7. The two parallel sets of rolling wheel structures 6 run on two tracks of the same traveling track 20. Each integrated machine has two lower traveling beams 7, also matched with two traveling tracks 20. In this embodiment, the tracks are made of double-jointed I40 I-beams welded together. The track connecting beams are made of channel steel, welded to the tracks at both ends. The traveling track 20 can be assembled in multiple sections. Track connectors are provided at both the front and rear ends of the traveling track 20. The traveling track 20 can be assembled together by fixing the track connectors with bolts. Preferably, a support block is installed at the front end of the traveling track 20 to prevent the rolling wheel structure 6 from traveling beyond the designed position. Regarding the aforementioned traveling track 20, since the supporting frame system tends to tilt outwards due to gravity when the reinforcing cage 18 is lowered, a supporting clamp 607 can be installed on the outside of the retaining steel frame 606. The upper end of the supporting clamp 607 is connected to the retaining steel frame 606, and the lower end extends to the outside of the traveling track 20. It has an inwardly protruding locking post that locks onto the outer side of the traveling track 20. In this embodiment, the traveling track 20 is made of I-beams, and the locking post is locked under the flange of the I-beam. The aforementioned rolling wheel assembly structure 6, traveling track 20, and beam surface support pad beam 21 help to reduce the overall height of the cantilever casting machine.

[0074] Furthermore, to facilitate the centralized prefabrication of the reinforcing cage 18 on the continuous beam 26 and reduce the use of large hoisting equipment, the cantilever casting integrated machine of this embodiment also includes a reinforcing cage assembly system. The reinforcing cage assembly system includes a reinforcing cage hoisting track 13, a crane 12, and a lifting mechanism. The reinforcing cage hoisting track 13 is fixed to the upper part of the support frame system. The crane 12 can move back and forth between the front and rear ends of the support frame system along the reinforcing cage hoisting track 13. The crane 12 is connected to a lifting mechanism for hoisting the reinforcing cage 18. The lifting mechanism includes a rotating lifting device 10. Since the reinforcing cage hoisting track 13 is provided, the reinforcing cage 18 can be lifted by the lifting mechanism, and then the crane 12 can be used to move from the rear end to the front end of the support frame system. In this way, the movement and hoisting alignment of the reinforcing cage in the support frame system can be realized, solving the problem of insufficient hoisting accuracy of large hoisting equipment.

[0075] Regarding the aforementioned support frame system, this embodiment provides a specific arrangement of the steel cage hoisting rail 13. The steel cage hoisting rail 13 is provided inside the upper load-bearing beam 15. In this embodiment, the upper load-bearing beam 15 is an L-shaped box beam, combined with... Figure 21 and Figure 22As shown, the two L-shaped box beams of the upper load-bearing beams 15 are arranged laterally with their bottoms facing each other, providing support for the steel cage hoisting track 13. This makes full use of the existing support frame system. This embodiment also provides a connection structure between the first front sling 17 and the rear sling 25 and the support frame system. The upper ends of the first front sling 17 are connected to both ends of the upper front crossbeam 16, and the upper ends of the rear sling 25 are connected to both ends of the upper rear crossbeam 19.

[0076] This embodiment provides a preferred structure for a rebar cage assembly system. To enable the rotation of the rebar cage 18, the lifting mechanism includes at least a rotating lifting device 10, with a rotation angle of not less than 90°. The rebar cage 18 is rotated 90° by the rotating lifting device 10 and then lowered into the continuous beam formwork. This effectively reduces the width of the support frame system and improves construction safety.

[0077] More specifically, this embodiment provides a lifting mechanism that is easier to achieve the purpose of the present invention, combined with Figure 3 and Figure 4As shown, the lifting mechanism includes a lifting beam 45, a lifting component 11, and a rotating lifting device 10. At least two lifting trolleys 12 are provided, connected by the lifting beam 45. The lifting component 11 is provided below the lifting beam 45, and the rotating lifting device 10 is suspended below the lifting component 11. The rotating lifting device 10 is used to lift and rotate the reinforcing cage 18. The upper end of the reinforcing cage hook 906 is connected to the longitudinal beam 903 of the hanger. In this embodiment, due to the large weight of the reinforcing cage 18, two reinforcing cage lifting tracks 13 can be provided for the lifting trolley 12. One track is provided on the inner side of each upper load-bearing beam 15. Four lifting trolleys 12 can be provided. The lifting trolleys 12 on the same track are connected by a lifting trolley connecting longitudinal beam. The lifting trolley connecting longitudinal beam is connected as a whole by a transverse lifting load-bearing beam 45. The lifting load-bearing beam 45 is connected to the lifting component 11, which can move laterally along the lifting load-bearing beam 45. This structure can use an existing gantry crane, or a lifting structure similar to that in a gantry crane, or a hoist crane with a drive structure to drive the hoist crane to move left and right. As the lifting component 11, it can also perform the functions of lowering and lifting the reinforcing cage 18. Furthermore, the rotating lifting device 10 uses an electric slewing mechanism. A common electric slewing mechanism is one where a motor drives a worm gear, which in turn drives a turbine to rotate, thereby rotating the rotating body. Electric slewing mechanisms are existing technology and will not be described in detail here. The prefabrication of the reinforcing cage 18 can be carried out in a factory, on the ground at the construction site, or centrally processed on the surface of the continuous beam. For ease of transportation, when constructing the No. 1 continuous beam segment, the reinforcing cage 18 is prefabricated on the ground at the construction site and hoisted to the support frame system or the front end by a tower crane. When constructing the No. 2 continuous beam segment and subsequent segments, it is centrally processed on the surface of the continuous beam. When the integrated machine travels to the front end of the already poured continuous beam segment via the traveling system, the reinforcing cage 18 is transported to the rear end of the integrated machine by a flatbed truck. The lifting device 11 is then used to hoist the reinforcing cage 18 from the rear end of the support frame system to the front end.

[0078] Based on the above-mentioned rebar cage assembly system, the specific steps for hoisting the prefabricated rebar cage 18 onto the bottom formwork 46 and between the outer formwork include: moving the hoisting mechanism to the rear end of the support frame system, hoisting the rebar cage 18, moving the rebar cage 18 along the rebar cage hoisting track 13 to the front end of the construction, rotating and moving the hoisting mechanism forward, backward, left and right, adjusting the angle, forward, backward and left and right orientation of the rebar cage 18 to be consistent with the angle, forward, backward and left and right orientation of the design position, lowering the rebar cage 18, and installing it into the design position in the continuous beam 26 formwork.

[0079] Furthermore, due to the considerable height of the reinforcing cage 18, which gradually decreases in height during construction, this embodiment provides a preferred improvement to the support frame system to ensure construction safety. The column 14 is chosen as a telescopic structure. The prefabrication of the reinforcing cage 18 can be completed at a fixed position on the continuous beam segment. However, the entire device for hoisting the reinforcing cage 18 still has a certain distance to travel to the next pouring segment. When the integrated machine moves as a whole using its traveling system, lowering the height of the column 14 lowers the center of gravity of the integrated machine, thus improving construction safety. Conversely, when hoisting the reinforcing cage 18 from the rear to the front of the support frame system, raising the height of the column 14 ensures that the reinforcing cage 18 passes smoothly without being obstructed by the support frame system. For the telescopic structure of the column 14, any structure that can achieve the telescopic function of the column is acceptable. For example, it can be a two-sleeve structure, including an upper column segment and a lower column segment. The lower end of the upper column segment is fitted around the upper end of the lower column segment and fixed with bolts. When it is necessary to adjust the height of the column, the bolts are released, and the upper column segment is moved up or down. After the movement is completed, it is fixed with bolts again. Of course, other forms that are easy to telescopic can also be used. The telescopic structure of columnar objects is existing technology and will not be described in detail here. When the frame diagonal brace 8 is provided between the columns 14, in order to adapt to different heights of the columns 14, the frame diagonal brace 8 is also set to be detachable. The connection between the frame diagonal brace 8 and the column 14 is bolted. According to the height of the column, the frame diagonal brace 8 of appropriate length can be selected for replacement, or alternatively, the frame diagonal brace 8 can also be a telescopic structure. For this embodiment Figure 2 and 3 The diagonal brace 8 shown is connected between the top of the column 14 and the middle of the longitudinal beam, and between the bottom of the column 14 and the middle of the longitudinal beam. The column 14 adopts a sleeve type. When adjusting the height of the column 14, the longitudinal beam is connected to the upper column segment. Therefore, the length of the diagonal brace 8 on the longitudinal beam does not need to be adjusted. Only the diagonal brace 8 below the longitudinal beam needs to be adjusted.

[0080] To ensure that the reinforcing cage is not easily deformed during hoisting, this embodiment also employs a multi-point lifting structure 9 for hoisting the reinforcing cage. The rotating lifting device 10 is connected to the multi-point lifting structure 9, combined with... Figure 22-25As shown, the multi-point hanger structure 9 includes a hanger crossbeam 904, a hanger longitudinal beam 903, connecting lugs 909, a flexible suspension unit 902, a rotating frame 901, and a rebar cage hook 906. At least two hanger crossbeams 904 are provided, connected by multiple hanger longitudinal beams 903. Connecting lugs 909 are provided on the hanger crossbeams 904, with at least four symmetrically arranged relative to the longitudinal centerline of the hanger crossbeams 904. These lugs are connected to the rotating frame 901 via the flexible suspension unit 902. The rotating frame 901 is connected to a rotating lifting device 10. The upper end of the rebar cage hook 906 is connected to the hanger longitudinal beam 903, and the lower end is used to hook the rebar cage 18. The rotating lifting device 10 rotates, causing the rotating frame 901 to rotate. The rotating frame 901 then rotates the hanger crossbeams 904 and the hanger longitudinal beams 903, thereby causing the rebar cage 18 to rotate. This embodiment shows 14 connecting lugs 909, with 7 connected to each hanger beam 904. One lug is located in the middle of the hanger beam 904, and three lugs are symmetrically arranged on each side relative to the longitudinal centerline of the hanger beam 904. The three connecting lugs 909 on the same side are each connected to one end of the corresponding side of the rotating frame 901 via steel chains or reinforcing bars. The middle connecting lug 909 is connected to the middle of the corresponding side of the rotating frame 901 via steel chains or reinforcing bars. The steel chains or reinforcing bars constitute the flexible suspension unit 902. The multi-point hanger structure 9 avoids deformation of the reinforcing cage 18 during hoisting and also solves the problem of uneven stress on the reinforcing cage 18 during hoisting.

[0081] Furthermore, the suspension mechanism includes a first front suspension strap 17 and a rear suspension strap 25. The first front suspension strap 17 has at least two straps, the upper ends of which are detachably connected to both ends of the upper front side of the support frame system, and the lower ends of which are connected to the front side of the bottom load-bearing mechanism. The rear suspension strap 25 has at least two straps, the upper ends of which are detachably connected to both ends of the lower front side of the support frame system, and the lower ends of which are connected to the rear side of the bottom load-bearing mechanism.

[0082] The specific steps for detaching the bottom formwork 46, outer formwork, and inner formwork from the already cast continuous beam segment 26 include: lowering the first front sling 17 and the rear sling 25 a certain distance; or adjusting the support frame system downwards a certain height and lowering the rear sling 25 a certain distance. Adjusting the support frame system downwards a certain height can be accomplished using the aforementioned retractable column 14.

[0083] More preferably, to better ensure the stability of the suspension, the suspension mechanism also includes at least one second front sling 31. The upper end of the second front sling 31 passes through the middle of the upper load-bearing beam 15 and can move up and down, while the lower end is detachably connected to the front side of the middle of the bottom load-bearing mechanism. In this embodiment, two second front slings are provided, symmetrically arranged on both sides of the middle of the upper load-bearing beam 15 to better ensure the load-bearing capacity during concrete pouring. The lower ends are detachably connected to both sides of the middle of the lower front crossbeam 1. However, since the reinforcing cage 18 may be obstructed by the second front sling 31 when rotating, the fixing structure between the second front sling 31 and the bottom load-bearing mechanism needs to be released before rotating the reinforcing cage 18, so that the second front sling moves upward. After the reinforcing cage 18 is installed, the second front sling is moved downward and then fixed to the bottom load-bearing mechanism. To facilitate the movement of the second front sling, a flexible structure, such as a steel chain or steel strand, can be used. The first front sling 17 will not collide with the reinforcing cage 18 and can therefore be a rigid structure, such as reinforcing bars or steel strips. The adjustment mechanism for the second front sling 31 can be mounted on the upper load-bearing beam 15 and can be achieved using existing transmission devices, such as the chain traction device in ZL201610637468.0.

[0084] When lowering the overall formwork mechanism, the connection between the second front sling 31 and the bottom load-bearing mechanism can be disconnected, or the length of the second front sling 31 can be adjusted simultaneously. When raising the bottom load-bearing mechanism, the suspension length of the second front sling 31 is also adjusted by moving the second front sling 31 upwards.

[0085] For the lowering of the first front sling 17 and the rear sling 25, the lowering adjustment can be achieved using existing methods for adjusting the suspension height with slings. This embodiment also provides a structure where, preferably, the first front sling 17 is detachably connected to both ends of the upper front side of the support frame system, and the rear sling 25 is detachably connected to both ends of the lower front side of the support frame system. This is to adjust the suspension height of the first front sling 17 and the rear sling 25 suspending the bottom load-bearing mechanism, adapting to the different beam heights of different continuous beam segments 26. For adjusting the suspension height, this embodiment provides a specific structure, with corresponding adjustments made on the upper front crossbeam 16 and the upper rear crossbeam 19. A first sling distribution beam is provided, and a second sling distribution beam is provided above the first sling distribution beam. A sling adjustment hydraulic jack is provided between the first sling distribution beam and the second sling distribution beam. A sling adjustment groove is provided vertically through the middle of the first sling distribution beam and the second sling distribution beam to accommodate the passage of the first front sling 17 / rear sling 25. Distribution beam pin holes are provided at the front and rear of the sling adjustment groove, which are provided horizontally through the first sling distribution beam / second sling distribution beam. Multiple sling pin holes are provided at intervals on the upper part of the first front sling 17 and the rear sling 25. Pins can be matched and inserted into the distribution beam pin holes and the sling pin holes to fix the first front sling 17 / rear sling 25. When adjusting the length of the first front sling 17 and the rear sling 25, first remove the pin threaded in the first sling distribution beam, then secure the pin threaded in the second sling distribution beam. Use the sling adjusting hydraulic jack to lift the slings, causing the first front sling 17 and the rear sling 25 to move upwards. After lifting, remove the pin threaded in the second sling distribution beam, insert a pin into the first sling distribution beam, and retract the sling adjusting hydraulic jack. The second sling distribution beam will then move downwards. Next, insert a pin into the second sling distribution beam, remove the pin threaded in the first sling distribution beam, and repeat the above steps until the length adjustment of the first front sling 17 and the rear sling 25 is complete. To lower the slings, simply reverse the operation.

[0086] This embodiment provides a preferred bottom load-bearing mechanism, including a lower front crossbeam 1 and a lower rear crossbeam 29; both ends of the lower front crossbeam 1 are respectively connected to the lower ends of the first front sling 17, and both ends of the lower rear crossbeam 29 are respectively connected to the lower ends of the rear sling 25.

[0087] The following provides a detailed explanation of the dismantling, replacement / adjustment, and closing of the formwork assembly. According to conventional design, the formwork assembly includes outer formwork, inner formwork, and bottom formwork 46. The bottom formwork 46 is located at the bottom of the outer formwork, and the reinforcing cage is placed between the outer formwork sections, with a passageway in between for the inner formwork.

[0088] The outer formwork includes an outer formwork web portion 30 and an outer formwork flange template portion 5. The outer formwork web portion 30 includes at least three detachable side plate segments, at least one of which is replaceable for replacement according to changes in the height of the continuous beam. In this embodiment, the replaceable side plate segment is located in the middle of the outer formwork web portion 30, with the upper and lower side plate segments having fixed heights. Figure 12 This embodiment illustrates that the outer mold web portion 30 includes three detachable side plate segments: a bottom side plate unit 3001, an adjusting section side plate unit 3002, and a top side plate unit 3003. The upper edge of the top side plate unit 3003 is connected to the outer mold flange template portion 5 and can slide outward together with it. The adjusting section side plate unit 3002 is a replaceable segment. Depending on the beam height and cross-section, the corresponding adjusting section side plate unit 3002 can be selected for replacement, avoiding the need to replace the entire outer mold web portion 30, thus reducing work difficulty and improving operational safety. Alternatively, depending on the actual situation, the outer mold web portion 30 can be divided into four side plate segments, two of which are replaceable. The joints between the side plate segments can be connected by double-row anti-misalignment bolts to ensure that the side plate segments are flush and the overall height adapts to the height of the segment beam. This allows the outer formwork to be replaced upwards as a whole, and the bottom side plate unit 3001 is basically flush with the bottom formwork 46. This is different from the traditional method of adjusting the height of the outer formwork segment downwards, and avoids the problems of height restriction at the bottom of the construction area and occupation of bottom space.

[0089] The specific process for adjusting the height and level of the outer mold and the elevation angle and height of the bottom mold 46 includes: disconnecting the connection between the top side plate unit 3003 and the adjusting section side plate unit 3002, moving the outer mold flange template part 5 and the top side plate unit 3003 outward; disconnecting the connection between the adjusting section side plate unit 3002 and the bottom side plate unit 3001, lifting the adjusting section side plate unit 3002 away, and hoisting the height-reduced adjusting section side plate unit 3002 to the replacement position; the newly replaced adjusting section side plate unit 3001... 002 is connected to the bottom side plate unit 3001, so that the newly replaced adjusting section side plate unit 3002 fits into the top side plate unit 3003, completing the connection and fixation of the newly replaced adjusting section side plate unit 3002 and the top side plate unit 3003; adjust the suspension height of the front and rear sides of the suspension mechanism to complete the adjustment of the angle and height of the bottom mold 46, and then adjust the angle and height of the outer mold web part 30 and the outer mold flange template part 5 to match the angle and height of the design position, completing the replacement and mold closing of the outer mold.

[0090] Furthermore, to facilitate and improve the automation level of outer mold replacement, such as Figure 3 , 12 As shown in -15, first... Figure 3 Provide an explanation. Figure 3 yes Figure 2 Structural diagrams of sections AA and BB (left view of the structure on the left, right view of the structure on the right). Figure 3 The main focus is on showcasing the cross-sectional structures of the inner and outer molds to facilitate understanding of the structure of the inner mold, bottom mold 46, and outer mold. The left half of the diagram shows a structural schematic of the BB section (near the lower front crossbeam 1), and the right half shows a structural schematic of the AA section (at the lower rear crossbeam 29). The template device also includes an outer mold support mechanism, which comprises an outer mold support gantry 3, a top support component 4, left and right telescopic components 35, an outer mold traveling trolley 34, a bottom support unit 2, and an angle adjustment component 38. Specifically, the outer mold support gantry 3 is located on the outer side of the outer mold web portion 30, specifically on the left and right sides of the outer mold web portion 30, with at least two rows on each side. It is a telescopic structure, combined with… Figure 15 As shown, this embodiment has 5 rows arranged parallel to each other along the longitudinal interval of the outer mold, corresponding to the position and number of the supporting trusses of the outer mold flange template 5; the top support member 4 is set on the top of the outer mold support gantry 3 and is provided with a transversely arranged outer mold traveling track. A top support member 4 is correspondingly set on the top of the outer mold support gantry 3 on the same side, which can ensure that the outer mold support gantry 3 stably supports the outer mold flange template 5, and provides guidance for the outward movement of the outer mold, and can also connect the outer mold support gantry 3 into a whole; the outer mold traveling trolley 34 is set below the outer mold flange template 5 and can slide laterally along the outer mold traveling track, thereby supporting the outer mold flange template 5 to slide outward. To ensure the smooth sliding of the outer mold flange template 5, the number of outer mold traveling trolleys 34 is determined according to the number of trusses of the outer mold flange template 5; the left and right telescopic members 35 are respectively set at the outer mold support gantry 3 and the top support member 4 facing outward. One side of the side mold web portion 30 is connected to the other end of the outer mold web portion 30. Left and right telescopic members 35, located on one side of the top support member 4, provide power for the outward movement of the outer mold flange template portion 5 and the top side plate unit 3003, and also provide support for the top side plate unit 3003. The left and right telescopic members 35, located on one side of the outer mold support gantry 3, provide support for the side plate segment below the top side plate unit 3003. Additionally, the left and right telescopic members 35 on one side of the outer mold support gantry 3 can adjust the angle to facilitate vertical adjustment of the side plate segment. The bottom support unit 2, connected to the lower end of the outer mold support gantry 3, provides support for the outer mold support gantry 3. The bottom support unit 2 includes a bottom support longitudinal beam 201 and a fixed support 202. The bottom support longitudinal beam 201 is connected to the lower end of the outer mold support gantry 3 via the fixed support 202. The bottom support longitudinal beams 201 are fixed together via a bottom load-bearing mechanism, ensuring the integrity of the entire support structure. Angle adjustment member 38, combined with... Figure 13 As shown, Figure 13 relatively Figure 12 The bottom support mechanism and angle adjustment component 38 are added. The upper end of the angle adjustment component 38 is connected to one side of the bottom support longitudinal beam 201, and the lower end extends vertically and connects to the bottom support mechanism. It is used to adjust the angle between the bottom support unit 2 and the bottom support mechanism. Here, "vertical" specifically refers to the arrangement in the up-down direction, not necessarily absolute verticality. The other side of the bottom support longitudinal beam is provided with a rotatable outer mold longitudinal beam hinge component 39 connected to the bottom support mechanism. In this embodiment, it is specifically hinged to the lower front crossbeam 1. The angle adjustment component can adjust the angle between the bottom support unit 2 and the bottom support mechanism, mainly by changing its length between the bottom support unit 2 and the bottom support mechanism. That is, it can be achieved by using a telescopic structure or a structure that can adjust the vertical distance. Since the distance between one side of the bottom support unit 2 and the bottom support mechanism changes, the angle between the other side and the bottom support mechanism also changes. Specifically, this embodiment provides a specific structure for the angle adjustment component 38, combined with... Figure 13 As shown, the angle adjustment component 38 includes a support screw, an upper adjusting nut, and a lower adjusting nut. The lower end of the support screw is connected to the bottom load-bearing structure, and the upper end of the support screw passes through the bottom support longitudinal beam 201. The portion above the bottom support longitudinal beam 201 is fitted with the upper adjusting nut, and the portion below the bottom support longitudinal beam 201 is fitted with the lower adjusting nut. The upper and lower adjusting nuts fix the upper end of the support screw in the bottom support longitudinal beam 201. When it is necessary to adjust the angle of the outer mold support gantry 3, the positions of the lower and upper adjusting nuts are adjusted, thereby changing the support length of the support screw, that is, changing the distance between the bottom support longitudinal beam 201 and the bottom load-bearing mechanism, thus achieving angle adjustment. It should also be emphasized that... Figure 12 The diagram shows only one side of the outer mold and its corresponding outer mold support gantry 3, top support support 4, left and right telescopic components 35, outer mold traveling trolley 34 and bottom support unit 2. The other side of the outer mold also has the above structures symmetrically arranged.

[0091] Furthermore, the outer mold support gantry 3 includes gantry uprights and gantry crossbeams 302. The two ends of the gantry crossbeams 302 are connected to the gantry uprights respectively. Each outer mold support gantry 3 is provided with at least two gantry uprights, which are connected to each other by the gantry crossbeams 302. The gantry crossbeams 302 can be made of steel plates and can also serve as an operating platform and passageway for operators. Alternatively, a patterned steel plate can be welded onto the gantry crossbeams 302 to serve as an operating platform 11. Furthermore, the gantry uprights include a first gantry upright 301 and a second gantry upright 303. In this embodiment, the first gantry upright 301 is selected as a hydraulic jack, and the second gantry upright 303 is a telescopic support rod, i.e., a mechanical lifting structure. The first gantry upright 301 and the second gantry upright 303 are arranged parallel to each other at intervals. The first gantry upright 301 provides power for telescopic movement, i.e., the piston extension and retraction of the hydraulic jack provides power for the telescopic movement of the gantry upright. The second gantry upright 303 provides stable support. The force can be a sleeve-type structure, divided into three sections. The upper and lower sections are respectively fitted onto the upper and lower ends of the middle section. The length of the second gantry upright 303 can be adjusted by adjusting the relative position of the upper or lower section with the middle section. After adjustment, the relative position of the upper or lower section with the middle section can be locked. There are various locking methods, such as tightening with bolts or locking with pins. Of course, the middle section can also be set as an external thread structure, and the upper and lower sections have an internal thread structure at the connection with the middle section. The middle section is rotated to achieve lifting and lowering. In the structure of this embodiment, the first gantry upright 301 is selected for one row of outer mold support gantry 3, and the second gantry upright 303 is selected for the adjacent row of outer mold support gantry 3. That is, the first gantry upright 301 and the second gantry upright 303 are set in parallel and spaced apart. According to the gantry upright structure of this embodiment, in order to provide strong support for the outer formwork, two left and right telescopic members 35 are provided on one side of the fixed part (i.e., the non-movable telescopic part) of the gantry upright near the outer formwork web portion 30, forming a triangular connection structure with the outer formwork web portion 30. That is, the ends of the two left and right telescopic members 35 connected to the fixed part of the gantry upright are close together, and the ends connected to the outer formwork web portion 30 are far apart, so as to form a stable support for the outer formwork web portion 30, supporting the construction load of the bottom side plate unit 3001 and the adjusting section side plate unit 3002 of the outer formwork. In addition, the left and right telescopic members can rotate at a certain angle to help realize the lifting and lowering of the outer formwork web portion. Specifically, the fixed part of the gantry upright, for the first gantry upright 301, can be the cylinder part of the hydraulic jack, and for the second gantry upright 303, it can be the lower section of the second gantry upright 303. The upper and lower ends of the gantry uprights are connected to the outer mold support longitudinal beam 402 and the bottom support longitudinal beam 201, respectively. Flanges are provided at the upper and lower ends, and bolts pass through the flanges and are screwed into the outer mold support longitudinal beam 402 and the bottom support longitudinal beam 201 to fix the upper and lower ends. The left and right telescopic parts 35 are electric push rods or hydraulic cylinders. In this embodiment, electric push rods are selected.

[0092] Furthermore, the top support component 4 includes an outer formwork support longitudinal beam 402 and an outer formwork support transverse beam 401. The outer formwork support longitudinal beam 402 is longitudinally connected to the top of multiple gantry uprights, and the outer formwork support transverse beam 401 is vertically connected to the outer formwork support longitudinal beam 402, and is equipped with an outer formwork travel track. The top support component 4 is designed to maintain its integrity with the outer formwork support gantry 3 and ensure the support strength for the outer formwork travel track and the top concrete. The top support structure includes a support truss for the outer mold flange template 5 as the main support rib. The outer mold support longitudinal beam 402 and the outer mold support cross beam 401 are welded together with lightweight steel sections. The outer mold traveling trolley 34 is composed of a lateral block, bearings, and rollers. The lateral block is connected to the rollers through the bearings. The outer mold traveling track is provided with grooves to allow the rollers to travel, preventing the outer mold traveling trolley 34 from detaching from the outer mold traveling track. The maximum lateral movement of the lateral block can be adjusted to 30cm to 45cm. A limit steel plate is fixed inside the outer mold traveling track to prevent the outer mold traveling trolley 34 from detaching from the outer end of the outer mold traveling track. The lateral movement driving force comes from the left and right telescopic members 35. When the bottom support is stable, the left and right telescopic members 35 extend and retract to drive the outer mold flange template 5 to move horizontally left and right on the outer mold traveling track based on the outer mold traveling trolley 34. Regarding the connection between the gantry uprights and the outer mold support longitudinal beam 402, this embodiment provides a specific structure. For the first gantry upright 301, a thread is provided at the top end of the first gantry upright 301, and a support nut 36 is provided at the bottom of the outer mold support longitudinal beam 402. The top end of the first gantry upright 301 is threadedly connected to the support nut 36, thereby fixing the first gantry upright 301 to the outer mold support longitudinal beam 402. For the second gantry upright 303, a stiffening plate can be provided at the top of the second gantry upright 303, and the second gantry upright 303 can be fixed to the outer mold support longitudinal beam 402 by welding the stiffening plate.

[0093] For the bottom mold 46, the supporting structure bottom mold longitudinal beam 37 under the bottom mold 46 is also set on the bottom load-bearing mechanism to provide a working support surface for it. In this embodiment, the lower front end of the bottom mold longitudinal beam 37 is connected to the lower front crossbeam 1, and the lower rear end is connected to the lower rear crossbeam 29.

[0094] The specific process of adjusting the height and level of the outer mold and the elevation angle and height of the bottom mold 46 includes: disconnecting the connection between the top side plate unit 3003 and the adjusting section side plate unit 3002; retracting the left and right telescopic members 35 connected to the top support member 4; moving the outer mold flange template part 5 and the top side plate unit 3003 outwards by relying on the outer mold traveling trolley 34 to provide sufficient hoisting and replacement space for the replacement of the adjusting section side plate segment 3002; disconnecting the connection between the adjusting section side plate unit 3002 and the bottom side plate unit 3001; hoisting the adjusting section side plate unit 3002 away using a tower crane; and hoisting the height-reduced adjusting section side plate unit 3002 to the replacement position; connecting the newly replaced adjusting section side plate unit 3002 to the bottom side plate unit 3001; extending the left and right telescopic members 35 connected to the top support member 4 outwards; and adjusting the angle of the left and right telescopic members 35 connected to the bottom side plate unit 3001 upwards and / or adjusting the height of the support gantry. The angle of the newly replaced adjusting section side plate unit 3002 is adjusted to fit with the top side plate unit 3003, thus completing the connection and fixation between the newly replaced adjusting section side plate unit 3002 and the top side plate unit 3003. The angle of the bottom load-bearing mechanism (in this embodiment, this is achieved by changing the height difference between the lower front crossbeam 1 and the lower rear crossbeam 29) and the height (in this embodiment, this is achieved by changing the hoisting length of the first front sling 17, the second front sling 31 and the rear sling 25) and the height of the support gantry are adjusted (the first gantry upright 301 and the second gantry upright 303 are adjusted to a suitable length according to the height of the continuous beam flange portion). The angle adjustment piece 38 at the rear end of the bottom support longitudinal beam 201 is retracted so that the elevation angle and height of the bottom mold 46 match the elevation angle and height of the designed beam segment bottom plate, and the support gantry is restored to a vertical state. The angle and height of the outer mold flange template portion 5 match the position of the designed beam segment flange plate, thus completing the replacement and closing of the outer mold.

[0095] Furthermore, the inner mold includes an inner mold top plate 40, inner mold side plates 42, and inner mold support trusses 22. Inner mold side plates 42 are arranged on both sides of the inner mold top plate 40, and inner mold support trusses 22 are spaced below. The shape and size of the inner mold top plate 40 and inner mold side plates 42 match the ducts in the middle of the continuous beam casting segment. Typically, the two inner mold side plates 42 are movably connected to the inner mold top plate 40, such as by hinges, which facilitates adjustment of the overall size of the inner mold and also facilitates installation and dismantling. Furthermore, an inner mold transverse telescopic rod 41 is fixedly installed inside the inner mold support truss. The width of the inner mold support truss 22 can be adjusted by the inner mold transverse telescopic rod 41. The inner mold support trusses 22 are interlocking and telescopic structures, similar to existing technology, where the width of the inner mold can be adjusted via the inner mold transverse telescopic rod 41.

[0096] The template device also includes an inner mold support mechanism; an inner mold support mechanism is installed inside the inner mold. The inner mold support mechanism includes an inner mold traveling mechanism 23, an inner mold support gantry 24, an upper chamfering telescopic component 32, and a lower chamfering telescopic component 33. The inner mold traveling mechanism 23 is fixedly installed below the inner mold support truss to drive the inner mold and provide support during concrete pouring. The inner mold support gantry 24 is height-adjustable and has template traveling guide rails on top for the inner mold traveling mechanism 23 to move the inner mold. The height of the inner mold support gantry 24 is adjusted according to the height of the middle duct of the continuous beam to adapt to the inner mold support requirements of different segments. The fixed end of the upper chamfering telescopic component 32 is connected to the inner mold support truss, and the telescopic end is connected to the upper part of the inner mold side plate; the lower chamfering telescopic component 33... The fixed end of the corner expansion member 33 is connected to the inner mold support truss, and the expansion end is connected to the lower part of the inner mold side plate. The upper chamfer expansion member 32 and the lower chamfer expansion member 33 are used to realize the quick demolding and demolding of the inner mold side plate, and provide strong support for the inner mold during concrete pouring to prevent deformation of the inner mold side plate. The bottom of the inner mold traveling mechanism 23 is provided with an inner mold suspension member 2305, and the side of the inner mold support gantry 24 is provided with a support gantry sliding track. The inner mold suspension member 2305 can slide in the support gantry sliding track.

[0097] For the aforementioned inner mold and inner mold support mechanism, moving the inner mold to the matching duct position in the middle of the reinforcing cage 18 specifically includes: shrinking the upper chamfered telescopic member 32 and the lower chamfered telescopic member 33 to shorten the height of the inner mold support gantry 24, so that the inner mold support gantry 24 is in a state where the inner mold suspension member 2305 is suspended. In the suspended state, the inner mold support gantry 24 is pushed forward so that the front part of the inner mold support gantry 24 is erected on the reinforcing cage 18 and the rear part is set at the bottom of the duct of the already poured continuous beam 26. The inner mold support gantry 24 is adjusted to a suitable height so that the inner mold traveling mechanism 23 can abut against the inner mold support truss 22. The width of the inner mold top plate 40 and the inner mold support truss 22 is adjusted, and the inner mold traveling mechanism 23 drives the inner mold to move forward to the designed position. The inner mold traveling mechanism 23 can be located above the front part of the inner mold support gantry 24. The upper chamfered telescopic member 32 and the lower chamfered telescopic member 33 are extended, and the inner mold is fixed to the outer mold by tie rods.

[0098] For the inner mold support gantry 24 and the inner mold traveling mechanism 23, this embodiment also provides a preferred structure. The inner mold support gantry 24 includes an inner mold support longitudinal beam 2401, an inner mold support column 2403, an inner mold support cross beam 2404, and an inner mold column adjusting screw 2402. The inner mold support longitudinal beam 2401, the inner mold support column 2403, and the inner mold support cross beam 2404 are connected to form a cubic support. The figure shows that there are four inner mold support longitudinal beams 2401. Figure 16As shown, there are two beams on each side. The vertical direction of the inner mold support beam 2404 is connected by the inner mold support column 2403, and the horizontal direction is also connected by the inner mold support beam 2404. The number of inner mold support longitudinal beams 2401, inner mold support columns 2403, and inner mold support beams 2404 can be adjusted according to the actual load-bearing requirements. The inner mold support column 2403 is made of steel pipe, and column connecting plates are welded to both ends. An inner mold column adjusting screw 2402 is fixedly installed at the bottom of the inner mold support column 2403. Specifically, the height of the inner mold support frame can be adjusted by adjusting the height of the inner mold column adjusting screw 2402. Of course, if the height adjustment is large, bolts can also be used to fix it for easy disassembly and replacement of the inner mold support column 2403 of appropriate length. The inner mold support column adjusting screw 2402 is also fixed to the bottom of the inner mold support column 2403 with bolts. The inner mold column adjusting screw 2402 can also be used to adjust the levelness of the entire inner mold support frame. Adjusting the height using a lead screw is existing technology, and any existing height-adjusting lead screw can be used. This embodiment also provides a preferred structure: the inner mold column adjusting lead screw 2402 includes a screw, a positive thread nut, a negative thread nut, a first support rod steel pipe, a second support steel pipe, and a connecting plate. A positive thread nut is provided at one end of the first support rod steel pipe, and a connecting plate is fixedly provided at the other end. A negative thread nut is provided at one end of the second support steel pipe, and the other end is fixedly connected to the bottom end of the inner mold support column. One end of the screw is threadedly connected to the positive thread nut, and the other end of the screw is threadedly connected to the negative thread nut. By rotating the screw, the gap between the first and second support steel pipes can be adjusted, thereby adjusting the height of the inner mold support mechanism. This design is easy to manufacture, simple to adjust, and can quickly adapt to support surfaces with different inclinations.

[0099] The inner mold support gantry 24 has a template traveling guide rail on its upper part for the inner mold traveling mechanism 23 to move the inner mold. There are two template traveling guide rails, which are arranged parallel to each other. The inner mold traveling mechanism 23 is provided on the template traveling guide rail. The inner mold traveling mechanism 23 is fixedly connected to the inner mold support truss 22 and can move the inner mold along the template traveling guide rail.

[0100] The inner mold traveling mechanism 23 includes an inner mold traveling wheel unit, an inner mold traveling base frame 2303, an inner mold support jack 2302, and an inner mold suspension component 2305. The inner mold traveling base frame 2303 is fixedly installed below the inner mold support truss, and the inner mold traveling wheel unit and the inner mold support jack 2302 are installed below it. The inner mold traveling wheel unit is used to drive the inner mold traveling base frame 2303 to move on the inner mold support gantry 24. The fixed end of the inner mold support jack 2302 is connected to the inner mold traveling base frame 2303. 303 and / or the inner mold support jack 2302 and / or the inner mold suspension component 2305 is provided. The inner mold suspension component 2305 has an inner mold suspension component 2305 at its bottom. The inner mold support gantry 24 is provided with a support gantry sliding track on its side. The inner mold suspension component 2305 can slide in the support gantry sliding track. When it is necessary to move the inner mold support gantry 24 forward, the inner mold support gantry 24 can be in a state of being suspended by the inner mold suspension component 2305. Pushing or driving the gantry support gantry forward is sufficient. In this embodiment, combined with Figure 21 As shown, the inner mold suspension components 2305 are located on both sides of the inner mold support jack 2302, and employ suspension wheels to reduce friction with the top surface of the supporting gantry sliding track. This embodiment also provides a preferred structure for the inner mold traveling wheel unit, which includes an inner mold traveling wheel set 2304 and an inner mold traveling trolley 2301. The inner mold traveling trolley 2301 is equipped with a power unit capable of driving the inner mold traveling wheel set 2304 to move. Combined with... Figure 9 As shown, the inner mold traveling trolley 2301 and the inner mold traveling wheel set 2304 are respectively connected to the inner mold. The inner mold traveling trolley 2301 and the inner mold traveling wheel set 2304 are arranged in a continuous line and can be simultaneously mounted on the template traveling guide rail. More specifically, combined with Figure 19 As shown, the structure of the inner mold traveling trolley 2301 is similar to that of the rolling wheel assembly 6. It also uses a drive motor, via a gearbox, to rotate the driving and driven wheels, thus moving the entire inner mold. Details are omitted here. The difference is that the number of inner mold traveling wheel assemblies 2304 is determined by the number of template traveling guide rails; each template traveling guide rail is matched with a set of driving and driven wheels. Combined with... Figure 20 As shown, the inner mold traveling wheel assembly 2304 includes a wheel assembly base frame and traveling wheels. The traveling wheels are rotatably mounted inside the wheel assembly base frame. A wheel assembly fixing part is also provided on the wheel assembly base frame for fixed connection with the inner mold template. The connection between the inner mold traveling trolley 2301, the inner mold traveling wheel assembly 2304, and the inner mold traveling base frame 2303 is similar to the connection method between the rolling wheel assembly structure 6 and the lower traveling beam 7, both using fork lugs and connected by pins. After the inner mold traveling trolley 2301 drive motor starts, the inner mold traveling wheel assembly 2304 also moves on the template traveling guide rail, thereby driving the entire inner mold to move.

[0101] like Figure 16 and Figure 18 As shown, an inner mold support jack 2302 is fixedly installed at the bottom of the inner mold traveling base 2303. The fixed end of the inner mold support jack 2302 is connected to the inner mold traveling base 2303, and the telescopic end abuts against the inner mold support gantry 24. When the inner mold traveling mechanism moves the inner mold to the appropriate position, the inner mold support jack 2302 is raised so that the inner mold is flush with the top of the inner ring of the continuous beam 26, and then concrete pouring can be carried out. The two ends of the inner mold support truss are respectively provided with the fixed ends of the upper chamfered telescopic member 32 and the lower chamfered telescopic member 33. The telescopic end of the upper chamfered telescopic member 32 is connected to the upper part of the inner mold side plate; the telescopic end of the lower chamfered telescopic member 33 is connected to the lower part of the inner mold side plate. Furthermore, a lateral support rod is provided between the lower parts of the two inner mold side plates. This lateral support rod is detachable and used during concrete pouring. It forms a triangular support with the lower chamfering telescopic component 33 for the inner mold side plate 42, ensuring the stability of the support. By adjusting the positions of the upper and lower chamfering telescopic components 32 and 33, the extension and retraction of the inner mold side plates can be changed to achieve automatic mold installation and removal. For ease of automatic control, the upper and lower chamfering telescopic components 32 and 33 can be hydraulic jacks or electric support rods. In this embodiment, electric support rods are preferred. After the jacks, telescopic components, and motors mentioned above are uniformly controlled by the controller, the automatic movement of the inner mold, automatic extension of the template, fixing, or removal of the template can be realized. Program control reduces manual intervention and further improves its automation level.

[0102] In conjunction with the above structure, this embodiment further explains the method of moving and disassembling the inner mold: When pouring concrete, the piston of the inner mold support jack 2302 extends downward to abut against the inner mold support gantry 24, thereby reducing the working load of the inner mold traveling wheel unit. The upper chamfered telescopic component 32, the lower chamfered telescopic component 33 and the side plate transverse support rod, together with the tie rod of the outer mold, keep it in the design position without deformation. After the inner mold is poured, the bottom load-bearing mechanism is lowered a distance as a whole, including the entire template of the inner mold, which is separated from the poured concrete structure. The specific process of moving and installing the inner formwork to the next continuous beam segment is as follows: The integrated machine travels to its position, and the outer formwork is installed. After the reinforcing cage is installed between the outer formwork segments, the upper chamfering telescopic component 32, the lower chamfering telescopic component 33, and the inner formwork support jack 2302 are contracted. The side plate transverse struts are removed, and then the height of the inner formwork support gantry 24 is shortened, so that the inner formwork support gantry 24 is in a state where the inner formwork suspension component 2305 is suspended. In the suspended state, the inner formwork support gantry 24 is pushed forward, so that the front part of the inner formwork support gantry 24 is placed on the reinforcing cage 18, and the rear part is set at the bottom of the already poured continuous beam duct. The inner formwork support gantry 24 is adjusted to a suitable height so that the upper part of the inner formwork traveling mechanism can support the inner formwork support truss, and the inner formwork traveling wheel unit can adhere to the formwork traveling guide rail. Figure 15 and Figure 16The image shows the inner mold support gantry in its forward-moved position. It should be noted that... Figure 16 In this state, the side plate transverse bracing has been removed. The diagram is only for illustration purposes, showing the installation position of the side plate transverse bracing during concrete pouring. Adjust the width of the inner mold top plate and the inner mold support truss. The inner mold traveling trolley 2301 starts, driving the entire inner mold traveling mechanism 23 to move forward, thus moving the entire inner mold to the designed position. The inner mold traveling mechanism 23 is positioned above the front of the inner mold support gantry 24. The upper chamfered telescopic component 32 and the lower chamfered telescopic component 33 extend. The inner mold is fixed to the outer mold via tie rods. The piston of the inner mold support jack 2302 extends downward, pressing against the inner mold support gantry 24. Figure 17 and Figure 18 The image shows the inner mold in its forward-moved position. The side plate transverse struts are then installed to support the inner mold, and the continuous beam segment is poured according to the inner mold installation.

[0103] Furthermore, the cantilever casting machine also includes a fulcrum lifting support mechanism 43, which includes a lifting jack 4302. The fixed end of the lifting jack 4302 is connected to the front end of the bottom of the support frame system; in this embodiment, it is connected to the front end of the bottom of the lower traveling beam 7.

[0104] When the cantilever casting machine is not in a traveling state, the piston of the lifting jack 4302 extends downwards to support the fixed structure below. In this embodiment, it supports the traveling track below it, but this can be adjusted according to the actual situation. The purpose of setting up this fulcrum lifting support mechanism 43 is that when the cantilever casting machine is hoisting the steel cage and formwork device, as well as pouring concrete segments, the cantilever casting machine tends to tilt forward. Setting up the fulcrum lifting support mechanism 43 can reduce the possibility of the rear side of the traveling mechanism detaching from the fixed structure below it. In this embodiment, it reduces the possibility of the rolling wheel assembly structure 6 detaching from the traveling track 20. At the same time, the fulcrum lifting support mechanism 43 also has the function of protecting the rolling wheel assembly structure 6, avoiding the entire working load being concentrated on the rolling wheel assembly structure 6.

[0105] Specifically, this embodiment also provides a fulcrum lifting support mechanism 43 that can form stable support, combined with Figure 8 and Figure 9As shown, it also includes a lifting distribution beam 4301 and a lifting lower pad 4303. At least two lifting jacks 4302 are provided; the upper part of the fixed end is connected to the lifting distribution beam 4301, and the lower part of the telescopic end is connected to the lifting lower pad 4303. That is, the top surfaces of two or more lifting jacks 4302 are connected through the lifting distribution beam 4301, and the bottom ends are connected through the lifting lower pad 4303. The connection to the support frame system is achieved through the bottom lifting distribution beam 4301. The upward lifting force of the jack 4302 is evenly transmitted to the lower traveling beam 7 through the lifting distribution beam 4301. The lifting lower pad 4303 can be matched and fastened to the upper part of the traveling rail 20. As shown in the figure, the lifting lower pad 4303 can have downwardly protruding lower pad positioning parts on both sides. The distance between the two lower pad positioning parts can match the upper part of the traveling rail mechanism, thus preventing displacement and evenly transmitting the supporting force of the traveling rail 20 to the lifting jack 4302. The fulcrum lifting support mechanism 43 also has the function of protecting the rolling wheel assembly structure 6, preventing the working load from being concentrated on the rolling wheel assembly structure 6.

[0106] Furthermore, the cantilever casting machine also includes an anchoring structure 27, which partially presses down on the bottom of the support frame system and extends toward the cast continuous beam 26 segment. It is detachably connected to the pre-embedded fixing parts embedded in the continuous beam 26 to prevent the support frame system from tilting forward.

[0107] For the support frame system of this embodiment, an anchoring structure 27 is provided between the lower traveling beam 7 and the cast continuous beam 26 segments. Any anchoring structure 27 that can hold down the lower traveling beam 7 and prevent the rear end of the support frame system from overturning forward is acceptable. This embodiment provides a preferred anchoring structure 27, such as... Figure 7 and Figure 8As shown, the anchoring structure 27 includes a roller pressure wheel 2702, a protective frame 2701, a connecting plate 2703, a connecting rocker arm 2704, and a spiral joint 2705. The length of the roller pressure wheel 2702 matches the downward-pressing traveling beam 7. The protective frame 2701 surrounds the roller pressure wheel 2702 on its upper and outer sides and is connected to the roller pressure wheel 2702 via bearings. The upper part of the connecting plate 2703 is connected to the protective frame 2701, and the lower end is rotatably connected to the upper end of the connecting rocker arm 2704. The lower end of the connecting rocker arm 2704 is detachably connected to the spiral joint 2705. The spiral joint 2705 has an internal thread extending upward from its lower port for fixing the pre-embedded threaded steel in the pre-embedded fastener. By setting the roller pressure wheel 2702 to press down on the downward-pressing traveling beam 7, when the hoisting device needs to move forward, the roller pressure wheel 2702 can rotate, ensuring efficient forward movement of the integrated machine with low frictional resistance. A protective frame 2701 is provided to protect the roller pressure roller 2702 from damage by rain and dust. The protective frame 2701 may include an upper sealing plate and side fastening plates. The two sides of the upper sealing plate are respectively connected to the side fastening plates. The roller pressure roller 2702 is located in the space enclosed by the upper sealing plate and the side fastening plates, and its two ends are respectively connected to the side fastening plates through bearings. The side fastening plates provide support for the rotation of the roller pressure roller 2702 and can work with the upper sealing plate to a certain extent to block rain and dust. More preferably, the protective frame 2701 also includes a front side plate and The rear side plate, upper sealing plate, side buckle plate, front side plate, and rear side plate surround the roller pressure roller 2702 from above and sides. Space needs to be left below for the roller pressure roller 2702 to press against the lower traveling beam 7. Specifically, the side buckle plate is preferably L-shaped in cross-section. The shortest distance between two side buckle plates is greater than the width of the lower traveling beam 7, and the distance between its bottom end and the upper sealing plate is greater than the height of the lower traveling beam 7. This prevents the roller pressure roller 2702 from slipping and ensures that the bearing can better perform its supporting function. In this embodiment, the roller pressure roller 2702 is a cast steel forged roller, and the protective frame 2701 is made of steel plate. A gap is provided between the rotating surface of the roller pressure roller 2702 and the upper sealing plate to ensure that the bearing performs its supporting function, while reducing rolling friction resistance. Simultaneously, it also ensures that the surface of the roller pressure roller 2702 in contact with the lower traveling beam 7 maintains good lubrication coverage, reducing contact resistance. Regarding the connection method of the connecting plate 2703, this embodiment also provides a preferred method: the upper part of the connecting plate 2703 is connected to the protective frame 2701, and a through hole is provided to accommodate the roller pressure roller 2702 passing through. Combined with the structure of the protective frame 2701 described above, the upper edge of the connecting plate 2703 is connected to the bottom surface of the upper sealing plate, and the upper front and rear edges are connected to the front side plate and the rear side plate, respectively, which can better fix the connecting plate 2703.In this embodiment, the upper end of the connecting plate 2703 and the connecting rocker arm 2704 are rotatably connected. The lower end of the connecting plate 2703 is provided with a pin hole, and the upper end of the connecting rocker arm 2704 is also provided with a rocker upper pin hole. Anchoring upper pins 2707 or upper bolts are inserted into the pin holes of the connecting plate 2703 and the rocker upper pin holes to connect the connecting plate 2703 and the connecting rocker arm 2704 together. With this rotatable connection, the rotatable connection can be adaptively adjusted to a certain angle during the forward movement of the hoisting device or when there is a slight forward tilt during the hoisting construction process, so as to maintain the downward verticality of the connecting rocker arm 2704. Choosing to use anchoring upper pins 2707 can better meet this requirement. When using anchoring upper pins 2707, the anchoring upper pins 2707 are connected to the connecting plate 2703 and the connecting rocker arm 2704 through bearings. This can greatly reduce the tendency to be dragged when the counter-pressure mechanism applies downward pressure. For the detachable connection between the lower end of the connecting rocker arm 2704 and the spiral joint 2705, the lower end of the connecting rocker arm 2704 is provided with a rocker arm lower pin hole, and the joint part is provided with a joint pin hole. Anchoring lower pins 2706 or lower bolts are inserted into the rocker arm lower pin hole and the joint pin hole to fix the connecting rocker arm 2704 and the joint part together. For the joint part, the specific structure adopted in this embodiment includes a horizontal steel plate and two vertical steel plates. The lower part of the horizontal steel plate is connected to the upper end of the spiral fastening part, and the upper part is connected to two parallel vertical steel plates. The gap between the vertical steel plates can match the insertion of the lower end of the connecting rocker arm 2704. The vertical steel plates are provided with joint pin holes, which correspond to the position of the rocker arm lower pin hole. This can better stabilize the connection with the connecting rocker arm 2704. The use of lower bolts here makes disassembly more convenient. With the above anchoring mechanism 5 technical solution, even during the movement of the integrated crane, the support frame system can be anchored to prevent it from tilting forward, and further prevent the integrated crane from tilting forward. More preferably, two sets of connecting plates 2703 are provided, and they are symmetrical about the vertical center line of the protective frame 2701. The spacing between the connecting plates 2703 is greater than the width of the traveling support mechanism 6. In this embodiment, the connecting plates 2703 are located inside the side buckle plate. Each set of connecting plates 2703 preferably includes two connecting plate 2703 units with a gap in the middle to accommodate the upper end of the connecting rocker 2704. This allows the connecting rocker 2704 to be clamped from both sides, preventing the lower traveling beam 7 from colliding and damaging the connecting rocker 2704, extending the service life of the anchoring device, and also better ensuring the stability of the connection.The anchoring process is as follows: When pouring the 26th segment of the continuous beam, the pre-embedded nut and pre-embedded threaded steel 28 are in the 26th segment of the continuous beam, and the upper end of the pre-embedded threaded steel 28 extends out of the 26th segment of the continuous beam. When pouring the next 26th segment of the continuous beam, the integrated machine moves above the pre-embedded threaded steel 28, presses the roller pressure roller 2702 on the lower traveling beam 7, disconnects the connection between the spiral joint 2705 and the connecting rocker arm 2704, tightens the spiral joint 2705 to the upper end of the threaded steel, rotates and lowers the connecting rocker arm 2704 so that the lower pin hole of the rocker arm and the pin hole of the joint are aligned, and fixes the connecting rocker arm 2704 and the spiral joint 2705 together with the anchoring lower pin shaft 2706 or the lower bolt, thus completing the overall anchoring of the integrated machine. When it is necessary to adjust the anchoring position of the counterweight roller mechanism, disconnect the connection between the spiral joint 2705 and the connecting rocker arm 2704, unscrew the spiral joint 2705, and adjust the anchoring structure 27 and / or the integrated machine to the appropriate position. During the travel of the traveling system and the hoisting of the reinforcing cage, the aforementioned anchoring structure 27 can prevent the bottom of the support frame system from tilting forward. In this embodiment, the length of the roller pressure wheel presses down on the traveling beam 7, which can prevent the entire support frame system from tilting forward. The number of anchoring structures 27 can be determined according to the actual situation, but at least one should be provided.

[0108] When the anchoring structure 27 obstructs the forward movement of the support frame system, the position of the anchoring structure 27 is adjusted so that it connects with the pre-embedded threaded steel bar 28 in the appropriate position.

[0109] Regarding the more specific structure described above, this embodiment provides a more detailed explanation of the casting method, specifically including: S1. Installing a cantilever casting machine, which includes a support frame system, a walking system below the support frame system, a suspension mechanism at the front end, and a bottom load-bearing mechanism connected to the lower end of the suspension mechanism for supporting the formwork device, the reinforcing cage, and the continuous beam 26 segments being cast. The formwork device includes a bottom formwork 46, an outer formwork, an outer formwork support mechanism, an inner formwork, and an inner formwork support mechanism; S2. The cantilever casting machine moves to the construction front end, assembling the bottom formwork, outer formwork, and outer formwork support mechanism on the bottom load-bearing structure. The front formwork is welded at the appropriate position of the prefabricated steel cage 18. At this point, the cross-section of the steel cage 18 is perpendicular to the installation cross-section. The machine is anchored using the anchoring structure 27. Then, the crane trolley 12 is moved close to the steel cage fabrication area. The tower crane lifts the steel cage 18 and places it on a flatbed truck for movement. The flatbed truck transports the steel cage 18 to below the crane trolley 12. The rotating lifting device 10 lifts the steel cage 18 and moves it to the construction front end. The rotating lifting device 10 rotates 90°, causing the steel cage 18 to rotate 90° as well. The steel cage 18 is lowered and installed on top of the bottom formwork 46, between the outer formwork. The columns 14 are shortened to reduce the height of the frame support system. The inner formwork and inner... After the formwork support mechanism is assembled, the first segment of concrete is poured; S3. Install the traveling track 20 and beam support pad beam 21 required for the next section of the cantilever casting machine to move. After the concrete has solidified and reached a certain strength, the formwork device is lowered a distance so that the bottom form, outer form, and inner form are separated from the poured continuous beam segment. The front form is moved away, and the bottom form 46, outer form, and outer form support mechanism follow the machine to the next pouring segment position. At this time, the outer form is replaced with one that matches the new beam segment height. The height and level of the outer form and the elevation angle and height of the bottom form are adjusted. The prefabricated steel cage is then hoisted onto the bottom form and between the outer forms. The inner form is moved to the matching hole position in the middle of the steel cage. After the formwork device is installed, concrete is poured. Repeat step S3 until the continuous beam is poured.
