Description

Technical Field

[0001] This invention relates to a formwork device for processing concrete grandstand panels, and more particularly to a T-shaped precast fair-faced concrete grandstand panel processing mold. Background Technology

[0002] Stadiums can host most kinds of sporting events. To accommodate as many spectators as possible, tiered stands are arranged from top to bottom, ensuring that everyone in the stadium has a seat and a good view. The design of the stands makes it more convenient for spectators to watch the game.

[0003] With the increasing popularity and assembly rate requirements of prefabricated and assembled buildings in my country's construction industry, the application of prefabricated fair-faced concrete grandstand panels in stadium-type buildings is gradually becoming more widespread. Traditional grandstand panels are poured on-site, which greatly affects the construction speed. Therefore, existing ones are often prefabricated directly in the factory. Factory prefabrication also allows for control of the quality of grandstand panels, reduces waste caused by rework, and is relatively energy-saving and environmentally friendly.

[0004] In the conventional production process of precast fair-faced concrete grandstand panels, the fixed dimensions of the grandstand panels and the molds make the process of tying reinforcing bars quite inconvenient. Workers find it difficult to operate within the narrow mold space, resulting in inadequate fixing of the reinforcing bars, wasting time. Furthermore, one mold can only be used for the production of one type of grandstand panel. When the dimensions of the grandstand panel change, the mold must also be modified accordingly, increasing processing time and resulting in extremely low efficiency. Summary of the Invention

[0005] This invention provides a T-shaped precast fair-faced concrete grandstand processing mold, which can effectively solve the above-mentioned problems.

[0006] This invention is implemented as follows:

[0007] A T-shaped precast fair-faced concrete grandstand panel processing mold, comprising:

[0008] A bottom support structure, wherein several guide rails are provided inside the bottom support structure;

[0009] A mold support structure welded to one side above the bottom support structure;

[0010] A plate-side mold welded in an inverted L-shape above the mold support structure;

[0011] An L-shaped short mold is slidably connected to the upper plane of the plate-side mold, with one side of the short end of the L-shaped short mold tightly attached to one side of the short end of the plate-side mold;

[0012] The inner template of the beam is vertically fixed above the plate side mold, and the inner template of the beam is suspended above the L-shaped short mold;

[0013] The outer template of the beam is welded to one side of the short end of the plate mold, and the outer template of the beam and the inner template of the beam form a beam-plate mold cavity;

[0014] A sliding structure that cooperates with the guide rail is locked onto the outer template of the beam.

[0015] A steel sheet welded above the plate-side mold, the steel sheet being at least longer than the plate-side mold;

[0016] Connecting rods are locked above the mold support structure, steel sheet, inner template of beam, and outer template of beam;

[0017] A sealing structure used to seal the front and rear ends of the inner cavity of the beam plate mold.

[0018] As a further improvement, the connecting rod includes pads that are respectively connected to the mold support structure, the steel sheet, the inner template of the beam, and the outer template of the beam, a longitudinal rod vertically welded to the pad, and a transverse rod connecting several of the longitudinal rods. The length of the longitudinal rods corresponding to the mold support structure and the steel sheet is greater than the length of the longitudinal rods corresponding to the inner template of the beam and the outer template of the beam.

[0019] As a further improvement, the bottom of the sealing structure is locked and fixed to the upper end of the L-shaped short mold, and the sealing structure slides when the L-shaped short mold slides.

[0020] As a further improvement, the sealing structure includes a fixed base for sealing the inner cavity of the beam plate mold, a push rod motor built into the fixed base, a supplementary plate connected to the output end of the push rod motor, and a sealing plate locked on the supplementary plate and flush with the fixed base.

[0021] As a further improvement, an anti-retraction structure is fixed to the outer side of the sealing structure. The anti-retraction structure includes a fixed head connected to the fixed seat, a straight arm inserted into the fixed head, and springs nailed to both sides of the straight arm. The outer sides of the two springs are respectively hinged to the hinge joints of the inner wall of the inner template of the beam and the inner wall of the outer template of the beam, for accommodating the hydraulic cavity of the straight arm. The two ends of the hydraulic cavity are fixed to the inner wall of the inner template of the beam and the inner wall of the outer template of the beam by several diagonal rods. The hydraulic cavity is connected to the external oil circuit.

[0022] As a further improvement, the sliding structure includes a sliding frame that cooperates with the guide rail, a support connecting plate that is locked onto the sliding frame and welded to the outer side of the outer template of the beam, and a pulley provided on the inner side of the sliding frame.

[0023] As a further improvement, the L-shaped short mold is mounted above the plate-side mold by a positioning structure. The positioning structure includes a positioning seat with a groove at the bottom, a positioning pin and a magnetic adsorption column disposed on the positioning seat. The groove is engaged with the L-shaped short mold, the positioning pin passes through the positioning seat and is locked onto the L-shaped short mold, and the magnetic adsorption column passes through the positioning seat and is adsorbed onto the plate-side mold.

[0024] As a further improvement, the L-shaped short mold is also provided with a pre-embedded hole structure, which includes an L-shaped fixed seat, a sliding sleeve slidably connected to one end of the long shaft of the L-shaped fixed seat, a positioning buckle welded to the sliding sleeve, and a long screw inserted into the positioning buckle and pointing towards the internal space of the L-shaped short mold.

[0025] As a further improvement, the mold support structure includes an upright long channel steel welded above the bottom support structure, and a transverse channel steel welded above the upright long channel steel for supporting the plate-side mold. The upright long channel steel, the transverse channel steel, and the top surface of the bottom support structure form a rectangular structure.

[0026] As a further improvement, the bottom support structure includes several steel pads placed on the ground, upright short channel steel welded to the steel pads, and a support frame welded to the top of the upright short channel steel. The upper part of the support frame is welded to the bottom of the mold support structure, the plate side mold, and the outer template of the beam, respectively. Several guide rails that cooperate with the sliding structure are provided on the inner side of the support frame.

[0027] The beneficial effects of this invention are:

[0028] This invention utilizes an L-shaped short mold. By sliding the L-shaped short mold on the side mold of the slab, the length of the mold can be changed. A sliding structure connecting the L-shaped short mold to the outer beam template allows for adjustment of the mold's width. The embedding of steel plates allows for adjustment of the mold's height. Through the coordination of these multiple structures, not only can multiple sizes and styles of grandstand slab structures be generated to meet the requirements of different stadiums, but also, when workers are arranging reinforcing bars, the pulling of the L-shaped short mold and the outer beam template provides sufficient space for workers to easily and accurately tie the reinforcing bars, ensuring that the generated grandstand slabs meet architectural requirements.

[0037] All embodiments of the present invention are intended to fall within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating that the purpose, technical solution, and advantages of the method are clearer. The technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] Existing concrete grandstand slabs use a single mold for each grandstand size, requiring dedicated molds for specific applications. This necessitates manufacturers preparing multiple sets of molds to serve different clients. Furthermore, the assembly of reinforcing bars within narrow mold openings is cumbersome and yields poor positioning and fixation of the bars, potentially affecting the grandstand's stability. To address these technical problems, this invention proposes the following solution:

[0040] Reference Figure 1-7 As shown, a T-shaped precast fair-faced concrete grandstand panel processing mold includes: a bottom support structure, the interior of which is provided with several guide rails 11; a mold support structure 2 welded to one side above the bottom support structure; a panel side mold 3 welded to the mold support structure 2 in an inverted L shape; an L-shaped short mold 4 slidably connected to the upper plane of the panel side mold 3, one side of the short end of the L-shaped short mold 4 being tightly attached to one side of the short end of the panel side mold 3; and a beam inner template 5 vertically fixed above the panel side mold 3, the beam inner template 5 being suspended in the air. Above the L-shaped short mold 4; a beam outer template 6 welded to one side of the short end of the plate-side mold 3, the beam outer template 6 and the beam inner template 5 forming a beam-plate mold cavity; a sliding structure 7 cooperating with the guide rail 11, the sliding structure 7 being locked onto the beam outer template 6; a steel sheet 8 welded above the plate-side mold 6, the steel sheet 8 being at least longer than the plate-side mold 6; a connecting rod 9 locked above the mold support structure 2, the steel sheet 8, the beam inner template 5, and the beam outer template 6; and a sealing structure 10 for sealing the front and rear ends of the beam-plate mold cavity.

[0041] First, it needs to be clarified that the height of concrete grandstand slabs is relatively fixed and within industry standards, which cannot be changed. The differences between different concrete grandstand slabs lie in their length and width, as well as whether they have raised steps, which is why different specifications of grandstand slabs are formed.

[0042] In this embodiment, the mold support structure 2 and the plate side mold 3 are first used to level the entire processing platform, so that the entire processing platform reaches a horizontal state, in order to ensure the levelness of the grandstand plate after molding.

[0043] Subsequently, an L-shaped short mold 4 was set up in this case. The L-shaped short mold 4 has an inverted L-shaped structure, with one end of its long end located on the side mold 3 and sliding horizontally on the side mold 3. The other side of the mold, opposite to the L-shaped short mold 4, remains stationary. Therefore, by sliding the L-shaped short mold 4 on the side mold 3, the length of the generated grandstand can be adjusted, so that a grandstand of the corresponding length can be obtained according to the customer's needs.

[0044] However, simply adjusting the length is not enough. Some customers, in more spacious venues, require the width of the grandstand to be increased in order to widen the distance between adjacent rows of seats. Therefore, in order to make the width of the grandstand adjustable, the inner beam template 5 is set as the fixed end, while the outer beam template 6, which is the movable end, is connected to a sliding structure 7 on its outer side. By sliding the sliding structure 7 on the guide rail 11, the distance between the outer beam template 6 and the inner beam template 5 can be changed, thereby adjusting the width of the grandstand.

[0045] Furthermore, when it is necessary to set up high and low embankments, steel plates 8 can be added and immersed in the poured concrete. After the concrete has solidified, the steel plates 8 can be removed to form a structure similar to high and low embankments. The height of the high and low embankments can be set according to the height of the steel plates 8, easily adapting to different requirements.

[0046] The above three methods can change the structure of the grandstand panel size, enabling the casting and molding of multiple grandstand panel sizes in the same set of molds. Manufacturers do not need to purchase multiple models of molds. Moreover, regardless of whether size adjustment is required, when workers are tying the reinforcing bars, they can first pull out the L-shaped short mold 4 and the outer formwork 6 of the beam to clear the entire construction space. Workers can operate in the internal space. After the reinforcing bars are tied, the L-shaped short mold 4 and the outer formwork 6 of the beam are put back in place without affecting the concrete pouring process.

[0047] After the production team adjusts the data of each structure, before pouring concrete, in order to avoid shaking or other degrees of swaying between the structures during concrete pouring, which would result in non-standard specifications of the formed grandstand panels, a connecting rod 9 is set above the mold support structure 2, steel sheet 8, inner beam template 5, and outer beam template 6. The above four components are connected by the same structure, so that there will be no structural displacement even during the concrete pouring process.

[0048] In addition, in order to prevent concrete leakage on one side of the short end of the T-shaped structure of the grandstand, a sealing structure 10 needs to be installed on both sides of the inner cavity of the beam mold formed by the outer formwork 6 and the inner formwork 5 of the beam to prevent the cement after pouring from flowing out from the gap between them.

[0049] In the application of connecting rod 9, it is firstly divided into three structural parts, specifically: the connecting rod 9 includes pads 91 that are respectively connected to the mold support structure 2, steel sheet 8, inner beam template 5, and outer beam template 6; longitudinal rods 92 vertically welded to the pads 91; and transverse rods 93 connecting several of the longitudinal rods 92. The length of the longitudinal rods 92 corresponding to the mold support structure 2 and steel sheet 8 is greater than the length of the longitudinal rods 92 corresponding to the inner beam template 5 and outer beam template 6. The pads 91 are fixed by welding, while the longitudinal rods 92 are connected by insertion and then welded. Finally, a uniform... The formwork support structure 2 and the inner template 5 of the beam are fixed in place and can be prefabricated. Since the positions of the outer template 6 and the steel plate 8 may change, after the manufacturer has adjusted all the structural positions and before pouring concrete, the corresponding longitudinal bars 92 are set for the outer template 6 and the steel plate 8. With the longitudinal bars 92 of the formwork support structure 2 and the inner template 5 of the beam fixed, the crossbar 93 can be well positioned and fixed. Even if the outer template 6 and the steel plate 8 may shake, their positions will not change due to the restraint of the other longitudinal bars 92.

[0050] Since the T-shaped grandstand panel is produced in this embodiment, the L-shaped grandstand panel formed by the L-shaped short mold 4 alone is not enough. It is also necessary to combine the inner cavity of the beam plate mold formed by the outer beam template 6 and the inner beam template 5 with the L-shaped short mold 4 to form a T-shaped structure. The length of the inner cavity of the beam plate mold must be the same as that of the L-shaped short mold 4 in order to form a T-shaped grandstand panel with equal length at the top and bottom. Therefore, the bottom of the sealing structure 10 is locked and fixed to the upper end of the L-shaped short mold 4. When the L-shaped short mold 4 slides, it drives the sealing structure 10 to slide. The sealing structure 10 follows the L-shaped short mold 4 to slide, which limits the length of the short end of the grandstand panel and makes the finished product neat. In addition, the inner beam template 5 needs to be suspended above the L-shaped short mold 4, which makes way for the L-shaped short mold 4 and can cooperate with the outer beam template 6.

[0051] During the pouring process, the L-shaped short mold 4 is poured first, and after the concrete in the mold has slightly set, the inner cavity of the beam and slab mold is poured. There is a time difference between the two pouring processes to prevent the concrete poured in the inner cavity of the beam and slab mold from overflowing through the L-shaped short mold 4.

[0052] As described above, the sealing structure 10 is used to seal both sides of the inner cavity of the beam-plate mold. However, due to different requirements, the width of the inner cavity of the beam-plate mold is actually variable. The existing solution is to replace different sealing structures 10 to adapt to the size changes. However, considering practical factors, some customers may have differences of only 1-2 cm. Manufacturing different sealing structures 10 for such a small range of differences would be wasteful. Therefore, to solve the problem of versatility, the sealing structure 10 includes a fixed base 101 for sealing the inner cavity of the beam-plate mold, a push rod motor 102 built into the fixed base 101, and a supplementary plate 1 connected to the output end of the push rod motor 102. 03. A sealing plate 104 is locked onto the supplementary plate 103 and flush with the fixed base 101. The width of the fixed base 101 is the width of the minimum grandstand plate. It is supplemented based on the minimum grandstand plate. When a larger sealing area is required, the supplementary plate 103 can be pushed out by driving the push rod motor 102, which extends the width of the fixed base 101 and thus seals the entire leakage surface. However, since the supplementary plate 103 is pushed out later, it will definitely not match the level of the fixed base 101 itself. Therefore, a sealing plate 104 needs to be set on the basis of the supplementary plate 103 so that the entire sealing structure 10 is a horizontal surface when it comes into contact with the concrete, and the resulting grandstand plate is a flat fair-faced concrete grandstand plate.

[0053] During the concrete pouring process, the concrete spreads to both sides. If the sealing structure 10 uses a sliding connection, it is easily pushed outward by the concrete, thus affecting the length of the short end of the T-shaped section of the grandstand. Therefore, an anti-retraction structure 20 is fixed to the outside of the sealing structure 10. The anti-retraction structure 20 includes a fixing head 201 connected to the fixed base 101, a straight arm 202 inserted into the fixing head 201, and springs 203 nailed to both sides of the straight arm 202. The outer sides of the two springs 203 are respectively hinged to the hinge joints 204 of the inner wall of the inner template 5 and the inner wall of the outer template 6 of the beam, for accommodating the hydraulic cavity 205 of the straight arm 202. The two ends of the hydraulic cavity 205 are fixed to the inner wall of the inner template 5 and the outer template 6 of the beam by several diagonal rods 206. The inner wall of the device 6 has a hydraulic chamber 205 that is connected to an external oil circuit. In use, firstly, the inclined rod 206 is fixed to secure the entire device. Then, the hydraulic chamber 205 is connected. The end of the hydraulic chamber 205 near the straight arm 202 is covered with a membrane to prevent hydraulic oil leakage while pushing the straight arm 202. Then, the hinge joint 204, spring 203, and straight arm 202 are installed. When the concrete is poured downwards and spreads to both sides, it will push the sealing structure 10 to move outwards, causing the straight arm 202 to be squeezed into the hydraulic chamber 205, while stretching the spring 203. After all the concrete has been poured, the user applies pressure to the hydraulic chamber 205 through the external oil circuit to push the straight arm 202 out and push the sealing structure 10 back to its original position to avoid affecting the length of the grandstand. At the same time, the spring 203 also returns to its original position.

[0054] It should be emphasized that since the position of the inner formwork 5 of the beam is fixed, while the position of the outer formwork 6 of the beam is variable, the hinge joint 204 and the diagonal bar 206 on the side closer to the inner formwork 5 of the beam are both welded and filled, while the hinge joint 204 and the diagonal bar 206 on the side closer to the outer formwork 6 of the beam are both snap-fit ​​connected, and the spring 203 can be stretched, and the tilt angle of the diagonal bar 206 is adjustable, which is quite flexible.

[0055] As described above, the outer formwork 6 of the beam is movable via a sliding structure 7. Specifically, the sliding structure 7 includes a sliding frame 71 that cooperates with the guide rail 11, and a support connecting plate 72 locked onto the sliding frame 71 and welded to the outer side of the outer formwork 6 of the beam. The inner side of the sliding frame 71 is equipped with pulleys. After adjustment, the outer formwork 6 of the beam is subjected to two types of fixing forces: one is the connecting and fixing effect from the top of the connecting rod 9, and the other is the pulling effect from the diagonal rod 206 and the hinge joint 204. This ensures that the sliding frame 71 will not change position even under pressure from concrete pouring after adjustment.

[0056] After resolving the sliding and fixing issues of the outer formwork 6 of the beam, the fixing issue after the sliding adjustment of the L-shaped short mold 4 needs to be addressed. Specifically, the L-shaped short mold 4 is installed above the plate-side mold 3 via a positioning structure 40. The positioning structure 40 includes a positioning seat 402 with a groove 401 at the bottom, a positioning pin 403 and a magnetic adsorption column 404 disposed on the positioning seat 402. The groove 401 engages with the L-shaped short mold 4, and the positioning pin 403 penetrates the positioning seat 402 and locks onto the L-shaped short mold 4. The adsorption column 404 passes through the positioning seat 402 and is adsorbed onto the side mold 3. After the L-shaped short mold 4 slides to a suitable position and the worker finishes tying the reinforcing bars, the bottom plate of the L-shaped short mold 4 is clamped by the positioning seat 402 and then locked onto the L-shaped short mold 4 by a positioning pin 403, completing the connection between the two. Then, a magnetic adsorption column 404 is used to adsorb the positioning seat 402 onto the side mold 3. Through the intermediate connection effect of the positioning structure 40, the L-shaped short mold 4 is tightly fixed onto the side mold 3, which effectively limits the length of the grandstand.

[0057] The plate-side mold 3 is made of iron, while the magnetic adsorption column 404 is made of magnet. Therefore, after the magnetic adsorption column 404 descends, it can be tightly adsorbed with the plate-side mold 3.

[0058] During the prefabrication of the grandstand panels, different holes need to be pre-drilled on the panels to facilitate the connection between panels and their coordination with other structures. To accommodate these pre-drilled holes, an embedded structure 41 is used during concrete pouring. Specifically, the L-shaped short mold 4 is equipped with an embedded structure 41 for the pre-drilled holes. This embedded structure 41 includes an L-shaped fixing seat 411, a sliding sleeve 412 slidably connected to one end of the long axis of the L-shaped fixing seat 411, and a fixing element welded to the sliding sleeve 412. Positioning buckle 413, long screw 414 inserted into positioning buckle 413 and pointing to the internal space of L-shaped short mold 4. First, determine the position of the hole to be reserved. Then, let sliding sleeve 412 slide on the long axis of L-shaped fixed seat 411. Slide it above the reserved hole position, so that long screw 414 on positioning buckle 413 drops. After the concrete is poured, remove long screw 414 to complete the reserved hole operation. Due to the sliding effect of sliding sleeve 412, holes can be reserved in different positions according to different customer needs.

[0059] As mentioned above, the mold support structure 2 and the plate-side mold 3 will establish a stable work surface. The specific structure of the mold support structure 2 is as follows: the mold support structure 2 includes an upright long channel steel 21 welded above the bottom support structure, and a transverse channel steel 22 welded above the upright long channel steel 21 and used to support the plate-side mold 3. The upright long channel steel 21, the transverse channel steel 22, and the top surface of the bottom support structure form a rectangular structure. First, in order to match the inverted L-shaped structure of the L-shaped short mold 4, the plate-side mold 3 also needs to be an inverted L-shaped structure, which is unavoidable. In order to adapt to the inverted L-shaped structure of the plate-side mold 3, the upright long channel steel 21 and the transverse channel steel 22 need to be combined to form a rectangular structure to fill the holes of the plate-side mold 3, thereby achieving the effect of stabilizing the horizontal surface.

[0060] Most of the above structures are made of steel or iron, and are extremely heavy. Therefore, a stable support structure is required, and it also needs to be easy to transport. Therefore, this embodiment provides a bottom support structure including several steel pads 12 placed on the ground, upright short channel steel 13 welded to the steel pads 12, and a support frame 14 welded to the top of the upright short channel steel 13. The upper part of the support frame 14 is welded to the bottom of the mold support structure 2, the plate side mold 3, and the outer template 6 of the beam. Several guide rails 11 that cooperate with the sliding structure 7 are provided on the inner side of the support frame 14. The upright short channel steel 13 suspends the entire support frame 14 in the air, which can provide a certain space for the installation and binding of the hoisted equipment during the hoisting process. In order to prevent the surface upright short channel steel 13 from exerting too much force on the ground, steel pads 12 are introduced to distribute the force of the entire structure on the ground.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
