The bottom surface of the board includes a positioning structure comprising angle steel, positioning tubes, and reinforcing bars. The angle steel is installed on the bottom surface of the side template and the end template. The positioning tubes are fixed to the side walls of the angle steel, and the reinforcing bars are clamped inside the positioning tubes. A step-by-step tightening mechanism is applied to the side walls of the wooden back braces of the two spliced ​​side templates. A fixing structure is clamped to the side walls of the side template and the end template. The fixing structure includes horizontal square steel, perforated steel, and vertical square steel. The horizontal square steel abuts against the side walls of the side template, and the vertical square steel abuts against the side walls of the end template. The perforations are equidistantly located on the side walls of the horizontal and vertical square steels, and the two ends of the vertical square steel abut against the side walls of the horizontal square steel.

[0007] Preferably, the width of the side template is between 300mm and 600mm, and the back of the side template is fixedly supported by 3 to 4 wooden back ribs with a spacing of 12mm to 15cm. The end template is erected between the inner side walls of the two side templates.

[0008] Preferably, the through holes are arranged in five vertical rows, with the spacing controlled from bottom to top.

Furthermore, by extending the wooden back braces fixed to the back of the end formwork outwards to form grooves, it facilitates later erection. These grooves abut against the ends of the side formwork, allowing for positional control. Secondly, by providing through holes on the side walls of the side formwork, with the spacing of these through holes gradually increasing from bottom to top, the bottom of the side formwork, after being fixed by tie rods, receives stronger support. Thirdly, by supporting the sleeves on the inner side walls of the formwork structure, and allowing the tie rods to pass through the sleeves, the sleeves can seal the through holes and prevent the middle section of the tie rods from contacting the concrete, facilitating later installation of the tie rods. The screw rods are removed by binding the positioning structure to the bottom of the pre-embedded positioning ribs, making the positioning structure a joint for erecting the template structure. This facilitates the positioning of the template structure, the alignment of the through holes, and the penetration of the tie rods. The connection nodes of the two side templates are clamped step by step, controlling the overlap gap between the two side templates to within 1mm. The fixing structure is clamped to the outer wall of the template structure and connected in series with the tie rods, thus tightening and fixing the template structure. This completes the erection of the template structure without the need for further drilling or cutting. This installation process causes minimal damage to the template structure. This template system has the advantages of increasing the number of times the template can be reused, reducing wood consumption, and facilitating template alignment and installation.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 ,in Figure 1 A schematic diagram of a preferred embodiment of the shear wall formwork system provided by this utility model; Figure 2 for Figure 1 The diagram shows a three-dimensional representation of the template structure. Figure 3 for Figure 1 A schematic diagram of the overall side view section shown; Figure 4 for Figure 3 The diagram shows a top-view cross-section of the template structure; the shear wall template system includes: a template structure 2, which is erected on the side wall of the shear wall 1. The template structure 2 includes side templates 21, timber back ribs 22, through holes 23, sealing plugs 24, and end templates 25. The side templates 21 are erected on the side walls at both ends of the shear wall 1. The through holes 23 are located on the side walls of the side templates 21. The end templates 25 are erected on the side walls at both ends of the shear wall 1. The sealing plugs 24 are used to seal the inside of the through holes 23. The timber back ribs 22 are fixed to the back of the side templates 21 and the end templates 25, and the timber back ribs 22 fixed to the side walls of the end templates 25 are slightly outward, so that the edge of the end templates 25 and the timber back ribs 22 form a groove; a positioning structure 6, which is installed on the bottom surface of the side templates 21 and the end templates 25. The positioning structure 6 includes an angle steel 61, a positioning tube 62, and a reinforcing bar 63. The angle steel 61 is installed on the bottom surface of the side template 21 and the end template 25. The positioning tube 62 is fixed to the side wall of the angle steel 61, and the reinforcing bar 63 is engaged inside the positioning tube 62. The step-by-step tightening 4 is applied to the side wall of the wooden back rib 22 of the two spliced ​​side templates 21. The fixing structure 5 is clamped to the side wall of the side template 21 and the end template 25. The fixing structure 5 includes a horizontal square steel 51, a through hole 52, and a vertical square steel 56. The horizontal square steel 51 abuts against the side wall of the side template 21 laterally, and the vertical square steel 56 abuts against the side wall of the end template 25. The through holes 52 are equidistantly arranged on the side walls of the horizontal square steel 51 and the vertical square steel 56, and the two ends of the vertical square steel 56 abut against the side wall of the horizontal square steel 51 respectively.

[0022] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3 As shown, the width of the side template 21 is between 300mm and 600mm, and the back of the side template 21 is fixedly supported by 3 to 4 wooden back ribs 22, with a spacing of 12mm to 15cm between the wooden back ribs 22. The end template 25 is erected between the inner side walls of the two side templates 21 at both ends. The through holes 23 are arranged vertically in five rows, with the spacing controlled from the bottom upwards. The vertical spacing is set to 150mm to 250mm for the bottom row and 150mm to 250mm for the second row. The spacing is set to 400mm~500mm, the third and fourth rows are set to 500mm-600mm, the fifth row is set to 500mm, and the horizontal spacing is set to 450mm. This facilitates the reinforcement of the side template 21 by the wooden back ribs 22, improves the overall rigidity of the template, and ensures that the bottom of the template structure 2 is denser than the top by the through holes 23. The fixing by the tie rods 54 can further strengthen the support of the bottom of the template structure 2 and reduce the expansion of the template.

[0023] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3 As shown, the fixing structure 5 further includes a pad 53, a tie rod 54, and a fixing nut 55. The tie rod 54 passes through the horizontal square steel 51 through the through hole 52. The pad 53 slides on the side walls at both ends of the tie rod 54. The fixing nut 55 is threaded to the side walls at both ends of the tie rod 54. The length of the tie rod 54 is greater than the width of the shear wall 1, and the side wall of the tie rod 54 is fitted with a sleeve 3. The length of the sleeve 3 corresponds to the thickness of the shear wall 1, and the sleeve 3 is supported between the inner side walls of the two side templates 21. The tie rod 54 also passes through the through hole 52. Hole 23 penetrates the side template 21; the center of both ends of the longitudinal square steel 56 is also provided with the through hole 52, and the tie rod 54 connects the longitudinal square steel 56 and the transverse square steel 51 through the through hole 52, and the pad 53 abuts against the side wall of the transverse square steel 51, and the fixing nut 55 abuts against the side wall of the pad 53; it is convenient to use the cooperation of the transverse square steel 51 and the longitudinal square steel 56, and under the series fixation of the tie rod 54, to clamp the side template 21 and the end template 25 inside, limit the side template 21 and the end template 25, and better ensure the cross-sectional dimensions of the wall column.

[0024] In the specific implementation process, such as Figure 1 , Figure 2 and Figure 3As shown, the length of the reinforcing bar 63 corresponds to the thickness of the shear wall 1, and the two ends of the reinforcing bar 63 are connected to the angle steel 61 by the positioning tube 62, so that the angle steel 61 can be positioned by tying the reinforcing bar 63 to the embedded bar, which facilitates the later installation of the side formwork 21 and the end formwork 25.

[0025] The working principle of the shear wall formwork system provided by this utility model is as follows:

[0026] First, cut the reinforcing bars 63 to the corresponding length according to the thickness of the shear wall 1. Then, tie and fix the reinforcing bars 63 to the pre-embedded positioning bars. Next, clamp the angle steel 61 to both ends of the reinforcing bars 63 through the positioning tube 62 to fix the position of the angle steel 61. Then, erect the angle steel 61 of the same length as the reinforcing bars 63 on the inner side of the positioned angle steel 61. Then, first, place the side formwork 21 on one side with the flat side facing inward, and erect it on the angle steel 61 on one side by hoisting to restrict the position of the side formwork 21. Then, the tie rod 54 passes through the through hole 23 provided in the side wall of the side formwork 21, and align the sleeve 3 with the... The through hole 23 on the inner side of the side template 21 allows the tie rod 54 to pass into the sleeve 3. The other side template 21 is then erected using the angle steel 61, with both ends of the sleeve 3 abutting between the two side templates 21. The tie rod 54 completely penetrates the sleeve 3 and exits through the through hole 23 on the side wall of the other side template 21. The end template 25 is then erected using the angle steel 61 on the inner side wall of one end of the two side templates 21, with both end side walls of the end template 25 abutting against the edges of the inner side walls of the side template 21. The wooden back brace 22, fixed to the back of the end template 25, abuts against one end of the side template 21. Then... Based on the length of the shear wall 1 to be poured, a corresponding side formwork 21 is assumed on the other end of the side wall of the side formwork 21 in the same row, and the side walls of the two side formwork 21 are brought together. Then, the step-by-step clamping 4 is used to clamp and fix the two formworks at the connection node, so that the length of the side formwork 21 corresponds to the length of the shear wall 1. In a synchronized operation sequence, the opposing side formwork 21 and the end formwork 25 are erected. Then, the horizontal square steel 51 is connected to both ends of the tie rod 54 through the through holes 52 on the side wall, so that the horizontal square steel 51 abuts against the side wall of the side formwork 21, and the longitudinal square steel 56 abuts against the end formwork 25. On the side wall of template 25, the two ends of the longitudinal square steel 56 abut against the side wall of the transverse square steel 51, and the through holes 52 at both ends of the longitudinal square steel 56 are aligned with the through holes 52 on the side wall of the transverse square steel 51. Then, the tie rod 54 connects the transverse square steel 51 and the longitudinal square steel 56 in series through the through holes 52, and the pads 53 are inserted into both ends of the tie rod 54. The tie rod 54 is then fixed by the fixing nuts 55, thus fixing the transverse square steel 51 and the longitudinal square steel 56. In this way, the transverse square steel 51 and the longitudinal square steel 56 tighten and fix the template. This template system has the advantages of facilitating the increase of template reuse, reducing timber consumption, and facilitating template alignment and installation.

[0027] Compared with related technologies, the shear wall formwork system provided by this utility model has the following beneficial effects:

[0028] This utility model provides a shear wall formwork system. Firstly, by fixing the wooden back ribs 22 to the back of the side formwork 21 and the end formwork 25, the support force of the formwork itself is strengthened. Furthermore, by extending the wooden back ribs 22 fixed to the back of the end formwork 25 outwards to form a groove, it facilitates later erection. The groove abuts against the end of the side formwork 21, facilitating positional restriction of the end formwork 25. Moreover, by providing through holes 23 on the side wall of the side formwork 21, with the spacing of the through holes gradually increasing from bottom to top, the bottom end of the side formwork 21, after being fixed by the tie rods 54, receives stronger support. The sleeve 3 is supported by the inner wall of the formwork structure 2, and the tie rods 54 penetrate the sleeve 3, allowing the sleeve 3 to seal the through holes 23. This also helps prevent the middle section of the tie rods 54 from contacting the concrete, facilitating later... The removal of the tie rod 54 is achieved by binding the positioning structure 6 to the bottom end of the pre-embedded positioning rib, making the positioning structure 6 a joint for erecting the template structure 2. This facilitates the positioning of the template structure 2, the alignment of the through hole 23, and the penetration of the tie rod 54. The connecting node of the two side templates 21 is clamped by the step-by-step clamping 4, controlling the gap between the two side templates 21 to within 1mm. The fixing structure 5 is clamped to the outer wall of the template structure 2 and connected in series with the tie rod 54, so that the fixing structure 5 clamps and fixes the template structure 2, thus completing the erection of the template structure 2. No further drilling or cutting is required on the template structure 2, and this installation process causes minimal damage to the template structure 2. This template system has the advantages of increasing the number of times the template can be reused, reducing wood consumption, and facilitating template alignment and installation.
