Description

Technical Field

[0001] The present application relates to the field of building expansion joint construction technology, and in particular to a expansion joint position synchronization construction device and a use method thereof. Background Art

[0002] At present, shear wall structures are widely used in domestic residential building structures. However, due to the relatively large height of current buildings, expansion joints need to be set between adjacent buildings or between two adjacent shear walls during the construction of shear walls, resulting in relatively large lengths and heights of expansion joints between buildings. In the prior art, the width of the expansion joints between buildings is generally 200mm-400mm, and shear walls are mostly located on both sides of the expansion joints.

[0003] During the pouring of the shear wall, since both sides need to be constructed simultaneously and the width of the expansion joint is relatively narrow, the construction workers cannot enter the expansion joint to support and reinforce the formwork. Therefore, in the prior art, in order to solve the problem of synchronous construction of the expansion joint between buildings, polystyrene boards are often fixed between the formworks used for pouring two adjacent shear walls, and the polystyrene boards are used to form the expansion joints and fixed to the formworks by screws.

[0004] Although this method can simultaneously carry out construction on both sides of the expansion joint, the strength of the polystyrene board is relatively low. Therefore, during the pouring of concrete, the pressure of the concrete and the vibration of the vibrating concrete are easily transmitted to the polystyrene board, causing the polystyrene board to deform or shift during the pouring and curing process, making it impossible to guarantee the thickness of the protective layer of the steel bars in the shear wall. In addition, during the removal of the polystyrene board, the polystyrene board cannot be reused, resulting in a large amount of material waste. Therefore, how to ensure the forming accuracy of the expansion joint while simultaneously carrying out the construction of the expansion joint position in a limited space is an urgent problem that needs to be solved. Summary of the invention

[0005] In order to perform synchronous construction of the position of the expansion joint within a limited space and optimize the forming accuracy of the expansion joint, the present application provides a synchronous construction device for the position of the expansion joint and a method for using the same.

[0006] The present application provides a synchronous construction device for expansion joint positions and a method for using the same, which adopts the following technical solutions:

[0007] In a first aspect, the present application provides a synchronous construction device for a deformation joint position, which adopts the following technical solution:

[0008] A synchronous construction device for the position of a deformation joint comprises side templates corresponding to both sides of the deformation joint, two forming templates arranged between the two side templates and a plurality of connecting mechanisms for connecting the two forming templates, wherein the side templates are parallel to the forming templates, and the outer walls of the two forming templates facing each other are fixedly connected with a plurality of vertically distributed fixed guide rails; the connecting mechanism comprises two connecting guide rails and a plurality of connecting pipes, wherein the connecting guide rails are horizontally arranged and slidably connected to the fixed guide rails along the length direction, and the plurality of connecting pipes are distributed along the length direction of the connecting guide rails, and the two ends of the connecting pipes are respectively threadedly connected to the two connecting guide rails; the forming templates are provided with a plurality of fastening mechanisms for connecting the side templates, and the fastening ends of the fastening mechanisms connected to the forming templates are plugged into the connecting pipes.

[0009] By adopting the above technical solution, during construction, it is only necessary to first install the two forming templates at the location of the deformation joint, and then install the side template, and fix the forming template and the side template through the fastening mechanism, so as to achieve the initial fixation of the two forming templates at the corresponding positions of the deformation joint; then, by sliding the connecting guide rail into the fixed guide rail, and connecting it to the connecting pipe through the fastening end of the fastening mechanism, the installation of the inner template and the forming template in the limited space is achieved; compared with filling polystyrene boards, directly using forming templates can effectively reduce the flatness and position deviation of the inner wall of the deformation joint after pouring, thereby optimizing the forming accuracy of the deformation joint.

[0010] After pouring is completed, when removing the formwork, you only need to remove the fastening mechanism relative to the shear wall first. When removing the forming formwork, you only need to slide the connecting guide rail relative to the fixed guide rail to reserve the movable space for the forming formwork relative to the cast forming shear wall. After that, the forming formwork is removed relative to the shear wall and the deformation joint is pulled out.

[0011] Optionally, plug-in tubes are sleeved on both ends of the connecting tube and threadedly connected thereto, and the two plug-in tubes on the connecting tube are respectively fixedly connected to two connecting guide rails.

[0012] By adopting the above technical solution, the connecting pipe is connected to the connecting guide rail by being inserted and threadedly connected to the plug-in tube, which can effectively optimize the load-bearing capacity between the connecting pipe and the connecting guide rail, so as to reduce the possibility of displacement between the connecting guide rail and the connecting pipe due to the load of the forming template during casting.

[0013] Optionally, the fastening mechanism includes a limiting tube, a limiting screw coaxially inserted through the limiting tube, and a limiting nut threadedly connected to the limiting screw, the limiting tube is located between adjacent forming templates and side templates, and both ends of the limiting tube are respectively abutted against the forming template and the side template, the limiting screw is inserted through the forming template and the side template abutted by the limiting tube and the connecting guide rail, the limiting screw is threadedly connected to the connecting tube, and the side template is clamped between the limiting tube and the limiting nut.

[0014] By adopting the above technical solution, when connecting the side formwork and the forming formwork, the distance between the side formwork and the forming formwork is first positioned by the limiting tube, and then the side formwork and the forming formwork are connected to the connecting tube by the limiting screw and the limiting nut, and positioned; and after the pouring is completed, due to the limitation and isolation of the limiting tube, the limiting screw can be pulled out without cutting off the limiting screw in the limited space, so as to further optimize the convenience during construction, and after the pouring is completed, the inside of the limiting tube is waterproofed and filled, for example, with waterproof mortar.

[0015] Optionally, the limiting tube includes a limiting main tube and two limiting pad tubes made of metal, the two limiting pad tubes are respectively inserted and fixed at both ends of the limiting main tube, and the two limiting pad tubes are respectively abutted against adjacent side templates and forming templates, the limiting screw is passed through the limiting main tube and the limiting pad tube, and the limiting pad tube is made of non-metallic material.

[0016] By adopting the above technical solution, the limiting gasket pipe can isolate the limiting main pipe from the outside after the waterproof material is filled inside, so as to reduce the possibility of oxidation of the limiting main pipe due to contact with the outside after pouring.

[0017] Optionally, a sealing assembly for sealing the limiting tube behind the forming shear wall is provided at the end of the limiting tube abutting against the forming template, and the inner wall of the limiting tube abutting against one end of the forming template is in a conical tubular structure and the large end is arranged toward the opening of the forming template; the sealing assembly includes a plurality of sealing plates for rotating and sealing the limiting tube and a sealing tube connected to the limiting tube and abutting against the inner wall of one end of the forming template, the sealing plate is fan-shaped and the sum of the central angles of the plurality of sealing plates is 2π, and the arc edge of the sealing plate is connected to the sealing tube, and the sealing tube is made of elastic material and is used to drive the sealing plate to rotate toward the center of the limiting tube.

[0018] By adopting the above technical solution, when the waterproof material is filled in the limiting tube, it is not convenient to seal the limiting tube due to the limited space in the deformation joint; at this time, in the process of the limiting screw pulling out the limiting tube, the sealing plate will be opened and spliced ​​with each other under the elastic tension of the sealing tube, so as to be used to seal the limiting tube against one end of the forming template, thereby restricting the flow of the waterproof material filled in the limiting tube, thereby further optimizing the convenience of construction in a limited space.

[0019] Optionally, a limiting ring is fixedly connected to the inner wall of the opening edge of one end of the limiting tube that abuts against the forming template, and the limiting ring is used to limit the rotation angle of the sealing plate, and the arc edge of the sealing plate is located outside the inner circle edge of the limiting ring.

[0020] By adopting the above technical solution, the limiting ring can limit the rotation angle of the blocking plate, thereby reducing the possibility of the blocking plate rotating toward the outside of the limiting tube due to the extrusion of the waterproof material, resulting in sealing failure.

The filling plate is fan-shaped and is arranged on the same central axis as the connected sealing plate. The thickness of the filling plate is the same as the thickness of the limiting ring along the central axis.

[0022] By adopting the above technical solution, the filling plate can fill the inner side of the limiting ring during the opening of the blocking plate, so as to reduce the influence of the setting of the blocking plate on the flatness of the inner wall of the deformation joint.

[0026] By adopting the above technical solution, the elastic net can optimize the tension of the driving tube body during elastic opening, so that the sealing plate can be opened in time after the limiting screw is disengaged, and after the sealing plate is opened, the filling glue in the driving tube body overflows, and plays a role of sealing and bonding the gaps between multiple sealing plates.

[0027] In a second aspect, the present application provides a method for using a synchronous construction device for a deformation joint position, which adopts the following technical solution:

[0028] A method for using a deformation joint position synchronization construction device comprises the following steps:

[0029] Fixing of forming plate: Fix the forming template through the connecting mechanism and pre-place it at the position corresponding to the deformation joint.

[0030] Side formwork fixing: The side formwork is connected to the forming formwork through a fastening mechanism, and the side formwork is fixed and positioned through diagonal braces.

[0035] During construction, it is only necessary to first install the two forming templates at the location of the deformation joint, and then install the side template, and locate the position between the forming template and the side template through the limiting tube, and simultaneously fix the forming template and the side template through the limiting screw and the limiting nut, so as to achieve the initial fixation of the two forming templates at the corresponding positions of the deformation joint; thereafter, by sliding the connecting guide rail into the fixed guide rail, and connecting it to the connecting tube through the fastening end of the fastening mechanism, the installation of the inner template and the forming template in the limited space is achieved; compared with filling polystyrene boards, directly using forming templates can effectively reduce the flatness and position deviation of the inner wall of the deformation joint after pouring, thereby optimizing the forming accuracy of the deformation joint and the convenience of construction.

DETAILED DESCRIPTION

[0042] The following is combined with Figure 1-5 This application is described in further detail.

[0043] Example 1

[0044] The present application embodiment discloses a device for synchronously constructing a deformation joint position. Figure 1 The synchronous construction device includes two side formworks 1, two forming formworks 2 and a plurality of connecting mechanisms 3. The side formwork 1 includes a plurality of formwork units 11 distributed in the horizontal direction, and the plurality of formwork units 11 are spliced ​​and arranged with each other. The formwork units 11 are made of steel plates or aluminum alloys, and the edges of the formwork units 11 are bent toward the same side. Reinforcing ribs are arranged on the inner side of the bent edges of the formwork units 11 to optimize stability during use. The forming formwork 2 has the same structure as the side formwork 1. The two forming formworks 2 are arranged between the two side formworks 1, and the two side formworks 1 are parallel to the forming formworks 2 and are arranged vertically. The two forming formworks 2 are used to form deformation joints. Among them, the forming formwork 2 is provided with a plurality of fastening mechanisms 4 for connecting the side formworks 1.

[0045] Reference Figure 2 and Figure 3 The outer walls of the two forming templates 2 on the opposite sides are fixedly connected with a number of vertically distributed fixed guide rails 21. The fixed guide rails 21 are U-shaped plate structures and the openings are facing the side away from the connected forming templates 2. The fixed guide rails 21 are horizontally arranged and fixedly connected to the template units 11 of multiple forming templates 2 by bolts, so as to connect the forming templates 2 as a whole and to connect with the connecting mechanism 3.

[0046] Specifically, the connection mechanism 3 includes two connection rails 31 and a plurality of connection tubes 32 distributed along the length direction of the connection rails 31. The connection rails 31 are perpendicular to the template unit 11 and are arranged horizontally. The two connection rails 31 are respectively clamped and slidably connected to the fixed rails 21 on the two forming templates 2. The sliding direction of the connection rails 31 is parallel to the fixed rails 21. Among them, the fixed rails 21 and the connection rails 31 are both U-shaped plate structures. The cross section of the inner wall of the fixed rail 21 is an isosceles trapezoid and is arranged with a large end opening for clamping the connection rails 31.

[0047] Reference Figure 2 and Figure 3 The connecting pipe 32 is arranged horizontally and perpendicular to the connecting guide rail 31. Both ends of the connecting pipe 32 are covered with plug-in pipes 311 with threads, and the plug-in pipe 311 is arranged coaxially with the connecting pipe 32. The plug-in pipe 311 is fixedly connected to the connecting guide rail 31. The two plug-in pipes 311 connected to the same connecting pipe 32 have opposite thread rotation directions, so as to control the distance between the two connecting guide rails 31 and achieve the purpose of controlling the width of the deformation joint.

[0048] The fastening end of the fastening mechanism 4 passes through the forming template 2 and is detachably connected to the connecting pipe 32, and the connecting guide rail 31 is formed with an avoidance groove 310 for avoiding the bolts on the connecting and fixing guide rail 21, and the avoidance groove 310 extends along the length direction of the connecting guide rail 31, and the bolts of the connecting and fixing guide rail 21 are inserted into the avoidance groove 310. Among them, the connecting guide rail 31 preferably adopts a plurality of guide rail units that are plugged into each other and fixed by bolts, for example, the ends of the guide rail units are stepped, and two adjacent guide rail units overlap each other and are fixed by bolts, so that when the connecting guide rail 31 is disassembled, the guide rail units are removed one by one, thereby reducing the space occupied during disassembly.

[0049] Reference Figure 2 and Figure 3 The fastening mechanism 4 includes a limiting tube 41, a limiting screw 42 and a limiting nut 43. The limiting tube 41 includes a limiting main tube 411 and two limiting washers 412. The limiting main tube 411 and the limiting washers 412 are both located between the adjacent side templates 1 and the forming template 2, and the limiting main tube 411 and the limiting washers 412 are arranged coaxially. The inner walls of the two ends of the limiting main tube 411 are in a stepped shaft-like structure and are arranged with a large end opening. The outer wall of the limiting washers 412 is also in a stepped shaft-like structure and the small end is coaxially plugged into the limiting main tube 411. The large end of the limiting washers 412 is in a tapered tube structure and is open at the large end. The ends of the two limiting washers 412 on the same limiting main tube 411 that are far away from each other are respectively abutted against the opposite side panels of the adjacent side templates 1 and the forming template 2, so as to be used for forming and adapting the thickness of the shear wall.

[0050] The limiting pad tube 412 is made of non-metallic materials, such as plastic, to separate the outside of the shear wall from the limiting main pipe 411 and the steel bars inside the shear wall, etc., to reduce the impact of oxidation of the limiting main pipe 411 and the steel mesh caused by contact with water and air outside the shear wall, and after construction, waterproof treatment can be performed by filling waterproof mortar and foam glue from the outside to the inside in the limiting main pipe 411 and the limiting pad tube 412. The outer wall of the limiting main pipe 411 is coaxially fixedly connected with a water stop ring 414, which is used for waterproofing between the limiting main pipe 411 and the shear wall after the shear wall is formed.

[0051] Reference Figure 2 and Figure 3 The limiting screw 42 is coaxially inserted through the limiting main pipe 411, the two limiting pads 412, and the forming template 2 and the side template 1 abutted by the connected limiting pads 412, and one end of the limiting screw 42 is inserted and threadedly connected to the connecting pipe 32, and the other end of the limiting screw 42 is threadedly connected to the limiting nut 43. The forming template 2 is clamped between the limiting pad 412 at one end of the limiting screw 42 facing the connecting guide rail 31 and the fixed guide rail 21, and the side template 1 is clamped between the limiting pad 412 at one end of the limiting screw 42 away from the connecting guide rail 31 and the limiting nut 43, so as to connect the side template 1 to the forming template 2.

[0052] Specifically, the outer wall of the side template 1 facing away from the forming template 2 is provided with a plurality of back ribs 12, the plurality of back ribs 12 are vertically distributed, and the template unit 11 of the side template 1 is fixedly connected to the back ribs 12 by bolts. The limiting screw 42 is passed through the back ribs 12, and the back ribs 12 are fastened to the template unit 11 by limiting nuts 43 or other bolts.

[0053] At the same time, in order to seal the end of the limiting tube 41 facing the deformation joint when filling the limiting main tube 411 with waterproof mortar or foam, a sealing component 44 is provided in the limiting pad tube 412 abutting against the forming template 2 to reduce the possibility of leakage of waterproof mortar, etc. due to the deformation joint being too narrow to seal the limiting tube 41.

[0054] Reference Figure 3 and Figure 4 Specifically, the sealing assembly 44 includes a sealing tube 442 and a plurality of sealing plates 441. The sealing tube 442 is a conical tube and is adapted to the inner wall of the limiting pad tube 412. The sealing tube 442 is fixedly connected to the inner side of the limiting pad tube 412 abutting against the forming template 2 with the same central axis, and the large end edge of the sealing tube 442 is bent inward. The sealing tube 442 is made of elastic material, such as a rubber tube or a silicone tube.

[0055] A plurality of sealing plates 441 are arranged around the central axis of the sealing tube 442. The sealing plates 441 are fan-shaped plate structures, and the arc edge of the sealing plates 441 is fixedly connected to the inner circle edge of the bending portion of the sealing tube 442. The sealing plates 441 follow the bending and rotating path of the edge of the bending portion of the sealing tube 442 and intersect with the central axis of the sealing tube 442. The sum of the central angles of the plurality of sealing plates 441 is 2π, so that under the action of the sealing tube 442, the plurality of sealing plates 441 can be driven to rotate toward the center of the sealing tube 442, and the plurality of sealing plates 441 can be spliced ​​with each other and seal the large end opening edge of the limiting pad tube 412 to limit the overflow of the waterproof mortar filled after pouring.

[0056] When in use, since the limiting screw 42 is inserted into the limiting tube 41, the blocking plate 441 is received inside the large end of the limiting pad tube 412 and the inner wall of the blocking tube 442 is bent. After the shear wall is cast, the limiting screw 42 is pulled out relative to the limiting tube 41. At this time, the blocking plate 441 rotates toward the center of the limiting tube 41 under the action of the blocking tube 442, so that multiple blocking plates 441 can be spliced ​​together and block the limiting pad tube 412 abutting against the forming template 2, without the need for manual entry into the deformation joint for sealing, thereby optimizing the convenience during construction.

[0057] Reference Figure 3 and Figure 4 In addition, in order to optimize the flatness of the multiple plugging plates 441 after splicing with the outer wall of the shear wall and limit the rotation angle of the plugging plates 441, the possibility of failure to block the limiting tube 41 due to the rotation transition of the plugging plates 441 is reduced. A limiting ring 413 is formed at the edge of the large end opening of the limiting pad tube 412 abutting against the forming template 2, and the bent portion of the plugging tube 442 is fixedly connected to the limiting ring 413. The outer wall of the limiting ring 413 is flush with the edge of the large end opening of the limiting pad tube 412, and the arc edge of the plugging plate 441 is located between the inner ring edge and the outer ring edge of the limiting ring 413, so that the rotation angle of the plugging plate 441 is limited by the limiting ring 413, and the possibility of mortar leakage due to the rotation transition of the plugging plate 441 is reduced.

[0058] Reference Figure 4 and Figure 5 The plate surface of the blocking plate 441 facing the limiting ring 413 is fixedly connected with a filling plate 443, which is a fan-shaped plate structure and is arranged coaxially with the connected blocking plate 441. The central angle of the filling plate 443 is the same as the central angle of the connected blocking plate 441, and the thickness of the filling plate 443 is the same as the thickness of the limiting ring 413. The diameter of the arc edge of the filling plate 443 is the same as the diameter of the inner circle of the limiting ring 413, so that the multiple blocking plates 441 can fill the inner circle of the limiting ring 413 after being unfolded, so as to optimize the flatness of the outer wall of the shear wall after the waterproof mortar is filled in the limiting tube 41.

[0059] Reference Figure 3 and Figure 4 Specifically, a driving tube 45 in the shape of an annular tube is provided on the inner side of the large end of the blocking tube 442 to assist in driving the multiple blocking plates 441 to rotate toward the limiting ring 413. The driving tube 45 includes a driving tube body 451 in the shape of an annular tube and an isolation net 452 fixedly connected to the inner wall of the driving tube body 451. The driving tube body 451 is made of elastic material, such as a rubber tube or a silicone tube. The driving tube body 451 is adapted to the inner wall of the large end of the blocking tube 442, and the blocking plate 441 is in contact with the outer wall of the driving tube body 451, so that the elastic bending of the blocking tube 442 can be coordinated through the elastic expansion and contraction of the driving tube body 451, so that the blocking plate 441 can be relatively fully attached to the limiting ring 413 after the limiting screw 42 is separated from the limiting tube 41.

[0060] Reference Figure 3 and Figure 4 At the same time, in order to optimize the ability of the driving pipe body 451 to adapt to deformation, drive the blocking plate 441 to rotate, and the blocking effect of the blocking plate 441, the isolation net 452 is an elastic net, such as a metal net, to support the driving pipe body 451. The driving pipe body 451 is filled with filling glue, such as building structural glue, expansion glue or sealant, preferably expansion glue. The driving pipe body 451 is provided with a plurality of connecting holes 453, and the blocking plate 441 is fixedly connected with a blocking block 444 plugged in and blocked in the connecting hole 453.

[0061] When the limiting screw 42 is pulled out relative to the limiting tube 41, the isolation net 452 in the driving tube body 451 will assist in pushing the driving tube body 451 to open, and cooperate with the resetting action of the bending part of the sealing tube 442 to push the sealing plate 441 toward the inner side of the limiting ring 413 and block the inner circle of the limiting ring 413; and in this process, the sealing block 444 will detach from the connecting hole 453, so that the filling glue overflows and fills the inside of the sealing tube 442, so as to be used as a seal between the sealing plates 441 and perform waterproofing.

[0062] Reference Figure 1 and Figure 2 In addition, in order to optimize the installation of the forming template 2 on both sides of the deformation joint, a plurality of connecting bottom rods 22 are passed through the bottom of the forming template 2, and the connecting bottom rods 22 are used to be connected to the floor slab of the floor through anchor bolts; and the connecting bottom rods 22 are passed through the two side templates 1, and the connecting bottom rods 22 are provided with a plurality of diagonal bracing rods 5.

[0063] The diagonal support rod 5 includes a telescopic screw tube 51 and two telescopic screw rods 52. The inner wall of the telescopic screw tube 51 is formed with threads at both ends, and the threads at both ends have opposite rotation directions. The two telescopic screw rods 52 are respectively inserted and threadedly connected to the two ends of the telescopic screw tube 51, so that the two telescopic screw rods 52 can be controlled to slide toward or away from each other through the telescopic screw tube 51. At the same time, one of the telescopic screw rods 52 is hinged to the back rib 12, and the other telescopic screw rod 52 is hinged to the connecting bottom rod 22, so as to support the side formwork 1.

[0064] Example 2

[0065] The embodiment of the present application also discloses a method for using a synchronous construction device for a deformation joint position. The method for using the synchronous construction device for a deformation joint position comprises the following steps:

[0066] Fixing of forming plate: fix the forming template 2 through the connecting mechanism 3 and pre-place it at the position corresponding to the deformation joint.

[0067] Specifically, the two ends of the connecting bottom rod 22 are placed across the position where the deformation joint is located, and the limiting tube 41 is placed on the connecting bottom rod 22 at the position corresponding to the casting shear wall. At the same time, multiple template units 11 of the forming template 2 are spliced ​​together and fixed to each other through multiple fixed guide rails 21; then the two ends of the connecting pipe 32 are respectively threadedly connected to the corresponding two connecting guide rails 31, and then the two connecting guide rails 31 are respectively slid into the fixed guide rails 21 on the two forming templates 2, and finally the two forming templates 2 are placed as a whole above the multiple connecting bottom rods 22 and are initially positioned by bolts.

[0068] Side formwork fixing: The side formwork 1 is connected to the forming formwork 2 through the fastening mechanism 4, and the side formwork 1 is fixed and positioned through the diagonal bracing rods 5.

[0069] Specifically, the multiple template units 11 of the side template 1 are spliced ​​together and fixed to each other through the back ribs 12, and then the limiting tube 41 is integrally covered with the limiting screw 42, and one end of the limiting screw 42 passes through the forming template 2 and is threadedly connected to the connecting tube 32, and the other end of the limiting screw 42 passes through the side template 1 and is threadedly connected to the limiting nut 43, and a cavity for casting the shear wall is formed between the side template 1 and the forming template 2, and a deformation joint is formed between the two forming templates 2.

[0070] Finally, one telescopic screw 52 of the diagonal support rod 5 is hinged to the back rib 12, and then the telescopic screw tube 51 is rotated so that the other telescopic screw 52 is hinged to the connecting bottom rod 22, thereby completing the fixing and positioning of the side template 1.

[0071] Casting: Cast concrete shear walls between adjacent side formwork and forming formwork.

[0072] Remove the formwork: remove the fastening mechanism, then slide the connecting rail relative to the fixed rail, and finally remove the forming formwork relative to the shear wall.

[0073] Specifically, the limiting screw 42 is first pulled out relative to the connecting tube 32, and in this process, the sealing plate 441 blocks the limiting pad tube 412, and multiple sealing plates 441 are bonded by filling glue; then the state of the forming template 2 is maintained, and the waterproof mortar is first filled in the limiting tube 41. At this time, the forming template 2 can assist in cooperating with the sealing plate 441, so that the waterproof mortar at the corresponding position of the limiting tube 41 is located in the limiting tube 41; then fill in the foam glue, and seal the limiting pad tube 412 on one side of the side template 1 through the plastic cover plate.

[0074] After the filling inside the limiting tube 41 is completed, since the limiting screw is detached from the connecting tube, the connecting guide rail can be pulled out relative to the fixed guide rail, so that the two forming templates can move relative to each other, and then the forming template 2 is removed, and the forming template 2 is pulled out as a whole and the template units 11 are removed one by one.

[0075] Finally, the connecting bottom rod 22 is pulled out relative to the shear wall, and waterproof mortar and foam glue are gradually filled into the limiting tubes 41 corresponding to the connecting bottom rod 22 for waterproofing.

[0076] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
