Description

Technical Field

[0001] This invention belongs to the field of civil engineering machinery and equipment technology, specifically relating to a tracked slipform device that combines a tracked splicing template system with a sliding frame inverted formwork system to enable the two to work together continuously. Background Technology

[0002] The sliding frame inverted formwork method is an improved process developed from the traditional slipform method. It is applied in the continuous construction of vertical concrete structures (such as core tubes, silos, chimneys, bridge piers, etc. of high-rise buildings). Its core feature is that the formwork itself does not slide continuously with the lifting system. Instead, it is lifted layer by layer upward along the back of the formwork by the sliding frame (or lifting frame). After the formwork is separated from the concrete, it is transported in sections to the upper layer for reuse, thereby realizing the functional separation of the formwork and the lifting system.

[0003] During construction, the formwork is assembled in one go, and then an operating platform is set up on top. Concrete is poured in layers from bottom to top, with each layer generally not exceeding 30cm in thickness. After the bottom layer of concrete reaches a certain strength, a lifting machine is used to slide the sliding frame upwards by about 30cm. At the same time, the bottom layer of formwork that has detached from the concrete is removed, cleaned, and transported to the upper layer for reinstallation. This cycle is repeated until the designed height is reached. Compared with traditional slipform construction, the formwork in the sliding frame method does not slide along the concrete surface. Instead, construction is achieved through the movement of the sliding frame and the relocation of the formwork. Therefore, the relative friction between the formwork and the concrete is smaller, the required lifting power is lower, and it is less likely to cause uneven lifting height due to friction.

[0004] However, the sliding frame casting method still has shortcomings in practical applications: First, because the formwork needs to be frequently moved, the process of dismantling, cleaning, and reinstalling each time is cumbersome, limiting construction efficiency. Second, during concrete pouring, some grout easily adheres to the formwork surface. If not cleaned in time, it will seriously affect the molding quality and service life of the formwork after the concrete has set. Traditional cleaning methods rely on manual shovels to clean the top of each formwork piece, which is inefficient, and the debris often falls into the gaps between adjacent formwork pieces, making it difficult to remove. In addition, after cleaning the formwork, a release agent (separator) needs to be applied before installation. This is usually done manually 1-2 hours before moving, using a spray gun, roller, or brush, which is time-consuming and makes it difficult to ensure uniform application. These problems restrict the further promotion of the sliding frame casting method.

[0005] Existing slipform systems include: Chinese Patent 202420904088.9 discloses a high-quality slipform template for silos, comprising an inner slipform template and an outer slipform template. Each of the inner and outer slipform templates has a dovetail groove on one side, with an inner wall plate slidingly engaging within the dovetail groove. Multiple inner wall plates are arranged in an arc shape and abut against each other. Multiple inner and outer slipform templates are also provided, abutting against each other. Each of the inner and outer slipform templates has a vertical rod fixedly connected to one side, with a sliding ring slidably connected to the vertical rod. Pull rods are rotatably connected to both sides of the sliding rings, with one end of each pull rod fixedly connected to… The system includes connecting plates, one of which is bolted to the inner slipform template, and the other to the outer slipform template. A sliding ring is bolted to uprights. A connecting rod is fixedly connected between the two uprights, each with multiple bolt holes arranged linearly and equidistantly. Guide blocks are fixedly connected to the bottom of both the inner and outer slipform templates. Limit plates are slidably connected to the guide blocks. Two guide blocks and limit plates are arranged in a mirror image, with a locking plate between them. The locking plate is rotatably connected to both the inner and outer slipform templates, and a handle is fixedly connected to its bottom. The system employs a combination of inner and outer slipform templates, using dovetail grooves to engage the sliding inner wall panel, improving the flexibility of template disassembly. The added linkage structure between the limit plates and guide blocks helps to cope with the slip resistance caused by concrete expansion. However, it lacks flexibility, is only suitable for fixed cross-section structures such as silos, cannot adapt to curved surfaces or variable cross-section conditions, has weak adaptability to different projects, relies on manual adjustment of limit plates, and has a low degree of automation. Chinese Patent 202320976445.0 discloses a tracked formwork, including a main frame and a secondary frame. Drive wheels are rotatably mounted on the secondary frame at intervals, and the drive wheels are connected to each other via tracked formwork transmission. A main frame for connecting other tracked formwork is installed inside the secondary frame. The tracked formwork is connected to a cavity for pouring concrete via the main frame. The upper end of the secondary frame is rotatably connected to a drive wheel via a telescopic adjustment device, and the lower end of the secondary frame is rotatably connected to a drive wheel via a bearing seat. The telescopic adjustment device includes a support connecting rod whose upper end is rotatably connected to the drive wheel, and whose lower end extends into and slides within the secondary frame. An adjusting nut is threaded onto the outer wall of the support connecting rod, and a spring is provided at the lower end of the adjusting nut. The tracked formwork uses rubber tracks, and aluminum alloy sheets are adhered to the outer wall of the tracked formwork. PTFE plates are provided on the two side walls of the secondary frame near the tracked formwork. It achieves normal demolding through a combination of rubber track molds and PTFE plates, reducing damage to the concrete surface. The track tension is dynamically controlled via an extension adjustment device to accommodate pouring deformation. However, its function is limited, only addressing demolding; it lacks cleaning and curing modules, resulting in insufficient construction continuity, requiring manual intervention to reset the tracks, and hindering simultaneous multi-process operations.

[0006] While existing building formwork and construction methods have made improvements in local structures (such as stability and curvature adaptability), they have not achieved full-process automation and integration, resulting in significant deficiencies in construction continuity, labor cost control, and multi-functional collaboration. Therefore, an integrated tracked slipform device is proposed, which uses tracked splicing formwork to transform the sliding friction between the traditional formwork and concrete into rolling and climbing. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and to develop and design a tracked sliding formwork device. By using the rolling and climbing method of the tracked splicing formwork system, the lifting resistance of the formwork is reduced, and the cleaning of the formwork is made more convenient.

[0008] To achieve the above objectives and solve the connection problem between the tracked splicing template system and the lifting system, the main structure of the tracked sliding formwork device involved in this invention includes a tracked climbing splicing template system and a sliding climbing sliding frame molding system that cooperate with each other, a lifting and operation system connected to the two, and a power system for lifting the splicing template system, the sliding frame molding system and the lifting and operation system.

[0009] The main structure of the splicing template system includes a support frame and driven large gears at its corners, support small gears and drag chain small gears on the sides, and external tracks.

[0010] The main structure of the sliding frame molding system includes mold templates that are set opposite each other;

[0011] The main structure of the lifting and operation system includes a frame that passes through and is fixedly connected to the support frame, a lifting frame connected to the frame, a slide rail between the frames, and an operation platform at one end.

[0012] The power system is a mechanism that can increase power, one type of which is a hydraulic jack. The hydraulic jack is wrapped around the support rod, and the bottom end of the support rod is fixedly connected to the frame.

[0013] The splicing template system involved in this invention is fixed to the lifting frame by a frame. The frame passes through the inside of the splicing template system and is connected and fixed to the support frame. The inner splicing surface of the splicing template system and the sliding frame casting system are on the same vertical plane. The two together provide a flat surface for concrete pouring. When the lifting frame climbs upward, the two are arranged at intervals, work together, and climb synchronously.

[0014] The track is spliced ​​together by several track plates. One splicing method is snap-fit ​​splicing. Specifically, a short arm with a groove is provided on the top of the track plate, guide teeth are provided on the side, and a short post matching the short arm is embedded in the lower part. Adjacent track plates are interlocked with each other through the short arm and the short post to form a continuous, dense, and flat surface. When the track rotates, it causes the track plates to slide and separate.

[0015] The outer side of the inverted formwork is matched with the slide rail. When pouring concrete, the slide rail slides upward with the lifting frame, forming a continuous flat surface in the splicing formwork system with a height similar to that of the inverted formwork.

[0016] Furthermore, sealing gaskets are installed at the bottom of the track plates to increase the airtightness when the track plates rotate, and to relieve the mutual compression between adjacent track plates when rotating to a position with greater curvature, thus ensuring smooth track rotation.

[0017] The innovation of the tracked slipform device involved in this invention lies in:

[0018] Tracked rolling template

[0019] The rolling formwork, which is spliced ​​by the sliding plates of the track, replaces the traditional sliding formwork. The relative movement between the formwork and the concrete surface is changed from sliding friction to rolling and climbing, which significantly reduces the lifting resistance and reduces the risk of tensile damage and cracking on the concrete surface.

[0020] Gear-induced gear cooperative transmission and support

[0021] By having the driven large gear, support small gear, and chain carrier small gear mesh with the guide teeth set on the track plate, the track can rotate smoothly, provide multi-point support and automatically tension, thus ensuring the rigidity of the template.

[0022] Dual-mode synchronous climbing mechanism

[0023] Tracked splicing templates and inverted templates are arranged at intervals and rigidly connected by a frame and a lifting frame to achieve synchronous upward sliding.

[0024] When used in conjunction with slipform, it can be used for the integral casting of complex structures such as corners, thus expanding its application range;

[0025] Automatic template splicing and discretization mechanism

[0026] The track plates automatically slide and splice or separate during rotation via internally inserted short columns and externally extended C-shaped short arms, forming a continuous, dense, and flat surface. This enables dynamic forming and detachment of the template without the need for manual assembly or disassembly, thus improving the level of automation.

[0027] Sealing gaskets relieve compression

[0028] Local rubber sealing gaskets are installed at the bottom of the track plates to alleviate the squeezing between adjacent track plates when the curvature increases, improve the smoothness of track operation in curved sections, and reduce mechanical wear and the risk of jamming.

[0029] Compared with existing technologies, this invention uses a tracked panel to form a rolling template. The template rolls and rises along the concrete surface, transforming traditional sliding friction into rolling friction, significantly reducing lifting resistance. Simultaneously, the tracked panel creates an open operating space on the rolling-out side (the side detached from the concrete), facilitating the integration of automatic cleaning and release agent spraying devices. This allows for the simultaneous and continuous execution of template cleaning, coating, and lifting operations, fundamentally solving long-standing technical problems in the sliding frame casting method, such as cumbersome template handling, low cleaning and coating efficiency, and difficulty in removing debris. Its simple structure and reliable scientific principle effectively reduce template lifting resistance, prevent concrete surface damage and cracking, improve construction continuity, enhance concrete forming quality, increase construction efficiency, and reduce labor costs and process fluctuations.

[0035] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1:

[0037] The main structure of a tracked sliding formwork device involved in this embodiment is as follows: Figure 1-2 As shown, the system includes a tracked splicing formwork system 1, a sliding frame casting system 2, a lifting and operating system 3, and a power system 4. The splicing formwork system 1 provides the formwork for concrete molding. The sliding frame casting system 2 is used to mold concrete and bear the lateral pressure and vibration load of the newly poured concrete. It also has the function of being detachable and reusable. Driven by the power system 4, the lifting and operating system 3 lifts the splicing formwork system 1 and the sliding frame casting system 2, as well as itself, and provides an operating area for construction. The power system 4 provides power.

[0038] Among them, the number of splicing template system 1 is 2, and the main structures of the two are as follows: Figure 3-4 As shown, the structure is mirror-symmetrical and includes a support frame 11, a driven large gear 12, a support small gear 13, a drag chain small gear 14, track plates 15, short arms 16, guide teeth 17, short columns 18, and sealing gaskets 19. Driven large gears 12 are located at each of the four corners of the support frame 11. Several support small gears 13 are located on the upper side, and several drag chain small gears 14 are located on the lower side. An external track is formed by several track plates 15 snapped together to form a tight track. A short arm 16 with a C-shaped groove is located at the top of each track plate 15. A pair of guide teeth 17 are located near the end of each inner side. A short column 18 matching the short arm 16 is located in the lower groove. A sealing gasket 19 is located at the bottom. Figure 5 As shown, adjacent track plates 15 are interlocked by an outwardly extending short arm 16 with a C-shaped groove and an inwardly embedded short post 18 with a buckle to form a continuous, dense, and flat surface. When the track rotates, it drives the track plates 15 to interlock and separate, ensuring that there is always a fixed plane to provide the template required for concrete pouring, so as to complete the concrete pouring and shaping. At the same time, there is always a fixed plane on the roll-out surface, which is convenient for construction personnel to clean in time.

[0039] The main structure of the sliding frame molding system 2 is as follows Figure 2 As shown, it includes two opposing mold templates 21;

[0040] The main structure of the enhancement and operation system 3 is as follows: Figure 2 As shown, it includes a frame 31, a lifting frame 32, a slide rail 33, a truss 34, and an operating platform 35; two frames 31, which are inserted into and fixedly connected to the support frame 11, are vertically fixedly connected to the lifting frame 32 with a portal-shaped structure. A slide rail 33 is provided between the frames 31 on the same side. One end of the frame 31 extends and is connected to the truss 34. An operating platform 35 is provided on the truss 34.

[0041] There are two power systems 4, and their main structures are the same, such as... Figure 2 As shown, it is set between the lifting frames 32, including a support rod 41 and a jack 42. The support rod 41 passes through the center of the jack 42 and its bottom is fixedly connected to the frame 31.

[0042] The support frame 11 involved in this embodiment is composed of two trapezoidal trusses with the lower chord as the common bar;

[0043] There are a total of 4 driven gears 12, which are installed at the corners of the support frame 11 and connected to each other by the horizontal crossbar of the support frame 11. They are installed at 1 / 4 of the total length from the outer edge of the track plate 15. The surface is evenly distributed with meshing teeth that match the guide teeth 17. Two concentric driven gears 12 are connected by a central bearing.

[0044] There are a total of 12 support pinions 13, which are installed on the upper horizontal crossbar of the support frame 11. They are arranged closely and mesh with the guide tooth 15 and the adjacent support pinion 13 at the same time to work together to provide support when the template formed by the sliding buckle of the track plate 15 contacts the concrete. Two concentric support pinions 13 are connected by a central bearing.

[0045] There are four track pinions 14 in total, with the same structure as the support pinions 13. They are evenly distributed on the lower horizontal crossbar of the support frame 11, away from the concrete pouring surface. They only mesh with the guide teeth 17 and rotate together, supporting the track from the side to give it a certain tension.

[0046] The two ends of the track plate 15 are stepped structures, which cooperate with the mold template 21. When moving, they press down on the stepped edges of the mold template 21 to ensure the airtightness of the splicing joint between the splicing template system 1 and the sliding frame mold system 2, prevent grout leakage and mutual collision, and at the same time ensure that the two do not move relative to each other.

[0047] When the track rotates, the guide tooth 17 meshes with the driven large gear 12, the support small gear 13 and the drag chain small gear 14, and rotates in coordination;

[0048] The sealing gasket 19 is located at the bottom of the track plate 15, with a right angle shape on the side near the concrete pouring surface and a curved shape on the side near the support frame 11.

[0049] The height of the inverted formwork 21 is generally 1.0-1.2m, which is determined according to the slip-lift speed and the time required for the concrete to reach the demolding strength. When the "pour-slip-one" process is used for construction, the outer formwork of the outer wall and part of the inner wall formwork are lengthened according to the construction requirements to enhance the anti-overturning stability in the slip-lift state.

[0050] The enclosure 31, the lifting frame 32, and the slide rail 33 are rigidly connected to form a whole and slide upward together. Specifically, the enclosure 31 and the lifting frame 32 are fixedly connected to form a frame, and a vertical slide rail 33 is fixedly installed on the inner side to support and fix the mold template 21. One slide rail is arranged at the top and one at the bottom to bear the horizontal lateral pressure transmitted from the mold template 21 and the vertical force generated by frictional resistance, the weight of the mold template 21 and the enclosure 31.

[0051] The lifting frame 32, also known as the jack frame or gantry, is symmetrically distributed on both sides of the mold template 21. It constrains and fixes the position of the frame 31, prevents the lateral deformation of the mold template 21, and connects the splicing template system 1 and the sliding frame mold system 2 with the lifting and operation system 3 into one unit. It bears all the load and transfers it to the jack 42.

[0052] The slide 33 is perpendicular to the enclosure 31, and its upper and lower ends are fixed to the upper and lower enclosures 31 respectively. It is fixed to the inner side of the enclosure 31, and the two are rigidly connected.

[0053] Truss 34 is the main load-bearing component, arranged in the form of a truss below the operating platform 35 to provide a supporting base for it and ensure its rigidity and stability.

[0054] The operating platform 35 is the main working surface for slipform construction. It is located above the splicing formwork system 1 and the slipform inverted formwork system 2. It is used to carry out operations such as rebar tying and concrete pouring, as well as to store some construction equipment and materials.

[0055] The support rod 41 is inserted in the center of the jack 42. It serves as both the track for the jack 42 to climb upwards and the load-bearing support for the splicing formwork system 1, bearing all the loads during the construction process.

[0056] The jack 42 has a through-hole structure. It provides power through the reciprocating motion of the internal piston, which drives the splicing template system 1, the sliding frame molding system 2, and the lifting and operating system 3 to steadily climb up along the support rod 41. The lifting height of each working stroke is between 20mm and 30mm. Through several cycles, the splicing template system 1, the sliding frame molding system 2, and the lifting and operating system 3 can be continuously and uniformly lifted upward.

[0057] Example 2:

[0058] When using a tracked sliding formwork device as described in this embodiment:

[0059] First, the splicing template system 1 and the sliding frame casting system 2 are distributed at intervals and symmetrically arranged on both sides of the wall to be poured;

[0060] A lifting frame 32 is distributed at set intervals on the outside of the splicing template system 1 and the sliding frame molding system 2. The lifting frame 32 is fixedly connected to the enclosure 31, and the enclosure 31 is fixedly connected to the position of the slide rail 33. The enclosure 31 is rigidly connected to the splicing template system 1. The operating platform 35 is fixedly connected to one side of the lifting frame 32 through the truss 34, located above the splicing template system 1 and the sliding frame molding system 2.

[0061] Install support rod 41 and jack 42 at the top of lifting frame 32, and connect support rod 41 to splicing template system 1 and sliding frame molding system 2;

[0062] Then, pour the first layer of concrete, about 600-700mm high, and wait for the concrete to reach the demolding strength (usually 0.2-0.5MPa, leaving a slight fingerprint when pressed by hand, and not sticky to the touch);

[0063] Finally, high-pressure oil is pumped into the jack 42 to push the piston to move and generate power. The force is then transmitted to the lifting frame 32 to drive the rigid whole consisting of the splicing template system 1, the frame 31, the lifting frame 32, and the slide rail 33 to slide synchronously along the support rod 41.

[0064] Initially, the inverted formwork 21 is fixed and maintains a clear distance of the same thickness from the poured concrete. Concrete is poured in layers. The stepped edges at both ends of the inverted formwork 21 are subjected to the pressure transmitted by the splicing formwork system 1. The two fit together and the splicing joint is tight.

[0065] Under the action of the bonding force of the poured concrete and the climbing force of the lifting frame 32, the left track rotates clockwise and the right track rotates counterclockwise. The driven large gear 12, the support small gear 13, and the chain small gear 14 work in coordination and mesh with the guide tooth 17 to rotate simultaneously.

[0066] The track plates 15 are connected by short arms 16 and short columns 18, which slide and interlock during rotation to form an integral plane (already coated with concrete release agent). This plane enters the concrete pouring surface and meshes with the support pinion 13. Under the support of the support pinion 13 and the frame 31, the integral plane has sufficient rigidity. There is internal support during concrete pouring. At this time, about 200-300mm of concrete is poured into the area where the steel bars have been tied.

[0067] At the same time, there is a part of the track that rotates away from the concrete pouring surface at the driven gear 12. The sealing gasket 19 of the track plate 15 at this location can alleviate the squeezing effect between adjacent track plates 15 at the point where the curvature increases. The short arm 16 and short column 18 between the track plates 15 slide and separate, and are driven by the meshing of the chain pinion 14 to maintain tension.

[0068] The slide 33 slides up with the frame 31, and the inverted formwork 21 is attached to the newly poured concrete surface and remains in place. The splicing formwork system 1 slides up synchronously with the frame 31. After the slide 33 slides up to the height of one layer of inverted formwork 21, the bottom layer of inverted formwork 21 is removed, cleaned, and then poured to the upper layer for use.

[0069] During the cycle of the power system 4 being raised at a set speed, concrete is continuously poured in layers, always keeping the top surface of the concrete inside the formwork 100-200mm away from the top of the formwork to prevent the formwork from being buried, while strictly controlling the demolding strength.

[0070] The pouring and lifting cycle is carried out until the construction is completed.

[0071] The technical effects achieved by the tracked sliding formwork device involved in this embodiment include the following:

[0072] Convenience of casting

[0073] The splicing template system and the sliding frame casting system work together to achieve the rolling and dynamic forming of the template through the automatic splicing and dispersing of the track plates. This eliminates the need for frequent disassembly, transportation and reinstallation of the template, greatly simplifies the casting process and significantly reduces the amount of manual operation and construction interruption time.

[0074] Template Cleanup Continuity

[0075] During the rolling and lifting process, the spliced ​​formwork system naturally forms a continuous, open and relatively fixed large planar operating space on the side detached from the concrete (roll-out surface). This facilitates timely cleaning of the formwork surface and removal of residual slurry by manual or integrated equipment, avoiding the problem of garbage falling into the formwork gaps and enabling the cleaning and lifting operations to be carried out simultaneously and continuously.

[0076] Release agent coating protection

[0077] The open space on the template rollout surface provides convenient conditions for automatic spraying or manual application of release agent (separating agent). Construction workers can apply it evenly immediately after cleaning without waiting or additional handling, which effectively improves the application efficiency and uniformity and ensures the quality of concrete molding.

[0078] Template connection reliability

[0079] The frame in the sliding frame molding system is inserted through the support frame of the splicing template system and rigidly connected to it, thereby achieving reliable fixation of the splicing template system and the lifting frame, ensuring that the two are lifted synchronously and stably under the drive of the power system, and solving the problem that the splicing template system cannot be directly connected to the lifting frame;

[0080] There is no relative movement between the two types of templates.

[0081] The splicing formwork system and the sliding frame inverted formwork system (inverted formwork) adopt an intermittent arrangement and synchronous lifting working mode. The two are designed with a stepped and mutually matching structure at the splicing joint. During the lifting process, they are pressed tightly against each other without relative sliding, which effectively prevents grout leakage, collision and misalignment, and further ensures the flatness and construction accuracy of the concrete structure.
