If the verticality does not meet requirements, the verticality of the formwork body can be adjusted by moving the sleeve vertically. While adjusting the verticality of the formwork body, the real-time changes in the verticality of the formwork body are observed using the verticality correction device. Based on the obtained verticality of the formwork body, the verticality of the formwork body is adjusted to adjust the verticality of the prefabricated shear walls installed inside the casting cavity. Therefore, the number of adjustments to the verticality of the prefabricated shear walls is significantly reduced, making the operation simpler, faster, and saving time. Furthermore, after the prefabricated shear walls are installed and hoisted, concrete can be poured into the casting cavity through the main and auxiliary pipes to form the prefabricated shear walls, making the shear wall pouring convenient and the operation simple.

[0035] The inventive concept of the present invention will be further explained below with reference to some specific embodiments.

[0036] This invention proposes a shear wall composite formwork 100, which includes a formwork body 10, a pouring pipe assembly 20, and a verticality correction device 30. The formwork body 10 includes two longitudinally spaced long side molds 11, two transversely spaced short side molds 12, and a vertically spaced bottom mold 13 and a top mold 14, which together form a pouring cavity. The pouring pipe assembly 20 includes a vertically extending main pipe 21 and a sleeve. The main pipe 21 is located near one of the short side molds 12. The sleeve 26 is slidably fitted on the outside of the main pipe 21. The sleeve 26 is also provided with a fastening structure 23, which fastens the sleeve 26 to the outside of the main pipe 21. The first end of the sleeve 22 is fixed to the outside of the sleeve 26 and communicates with the main pipe 21. The second end of the sleeve 22 is fixed to the corresponding short side mold 12 of the main pipe 21 and communicates with the casting cavity. The verticality correction device 30 is installed on one of the long side molds 11 and is located away from the casting pipe assembly 20.

[0037] Specifically, as shown in the figure, the vertical direction is attached. Figure 1 The vertical direction is in the middle, and the horizontal direction is attached. Figure 1 The left and right directions are in the middle, and the vertical direction is attached. Figure 1 In the formwork, a main pipe 21 is installed vertically on the ground, and a sleeve 26 is fitted onto the main pipe 21. The sleeve 26 can slide vertically on the main pipe 21 and can be fixed to the main pipe 21 by a fastening structure 23. On one side of the main pipe 21, two long side molds 11 are assembled vertically, two short side molds 12 are assembled horizontally, and a bottom mold 13 and a top mold 14 are assembled vertically to form the formwork body 10. A secondary pipe 22 is installed on the sleeve 26. The first end of the secondary pipe 22 is fixed to the secondary pipe 22 and communicates with the main pipe 21. The second end of the secondary pipe 22 is installed on the short side mold 12 on the other side and communicates with the pouring cavity. The other side of the formwork body 10 can move vertically along the sleeve 26 under the drive of the secondary pipe 22 to adjust the height difference between the other side and one side of the formwork body 10. By adjusting the height difference between the other side and one side of the formwork body 10, the verticality of the formwork body 10 can be adjusted. A verticality correction device 30 is installed on the long side mold 11 at the front of the formwork body 10 to measure the verticality of the formwork body 10. During the hoisting of the prefabricated shear wall, the prefabricated shear wall is installed in the pouring cavity of the formwork body 10. First, the verticality of the formwork body 10 is obtained by observing the verticality of the formwork body 10 to obtain the verticality of the prefabricated shear wall installed in the formwork body 10. If the verticality does not meet the requirements, the verticality of the formwork body 10 can be adjusted by moving the sleeve 26 in the vertical direction. While adjusting the verticality of the formwork body 10, the real-time change of the verticality of the formwork body 10 is observed by the verticality correction device 30. Then, the verticality of the formwork body 10 is adjusted according to the obtained verticality of the formwork body 10 to adjust the verticality of the prefabricated shear wall installed in the pouring cavity of the formwork body 10. Therefore, the number of adjustments to the verticality of the prefabricated shear wall is significantly reduced, the operation is simpler, the time is shorter, and time is saved. Furthermore, after the prefabricated shear wall is installed and hoisted, concrete can be poured into the casting cavity through the main pipe 21 and the auxiliary pipe 22 to form the prefabricated shear wall into a shear wall. The shear wall casting is convenient and the operation is simple.

[0038] In one embodiment, the top and bottom ends of the main tube 21 are respectively provided with an upper limit structure 24 and a lower limit structure 25, wherein the upper limit structure 24 is used to abut against the top of the sleeve 26, and the lower limit structure 25 is used to abut against the bottom of the sleeve 26.

[0039] Specifically, such as Figures 1 to 3As shown, the sleeve 26 can slide on the main pipe 21 in the vertical direction. The upper limit structure 24 and the lower limit structure 25 can abut against the sleeve 26 to prevent the sleeve 26 from falling out of the main pipe 21 when sliding. The structure is safer and more durable.

[0040] In one embodiment, the upper limit structure 24 is an upper limit ring encircled at the top of the main tube 21, and the lower limit structure 25 is a lower limit ring encircled at the bottom of the main tube 21.

[0041] Specifically, such as Figure 1 and Figure 3 As shown, the upper limit structure 24 and the lower limit structure 25 are the upper limit ring and the lower limit ring, respectively, which are ringed on the top and bottom of the main pipe 21. They can more fully abut against the sleeve 26, prevent the sleeve 26 from coming out, and have a good limiting effect.

[0042] In one embodiment, the fastening structure 23 includes a screw and a knob. A screw hole is formed on the sleeve 26. The screw passes through the screw hole and is threaded into the screw hole. A knob is installed at the end of the screw that extends out of the sleeve 26. The end of the screw that extends into the sleeve 26 is used to press against the main tube 21.

[0043] Specifically, when the sleeve 26 needs to slide, rotating the knob moves the screw away from the main pipe 21 and disengages it from the main pipe 21. The screw is not fastened to the main pipe 21, making it easy to adjust the height of the sleeve 26. When the sleeve 26 needs to be fixed to the main pipe 21, rotating the knob in the opposite direction moves the screw closer to the knob and presses it against the main pipe 21, thus fastening the screw to the main pipe 21. This achieves the purpose of fastening the sleeve to the main pipe 21, making the operation simple and convenient.

[0044] In one embodiment, there are multiple sleeves 26 and multiple secondary tubes 22. Multiple sleeves 26 are arranged vertically at intervals on the outside of the main tube 21, and multiple secondary tubes 22 are arranged vertically at intervals. The number of secondary tubes 22 and sleeves 26 are the same and they are fixed in a one-to-one correspondence.

[0045] Specifically, such as Figure 1 and Figure 3 As shown, multiple sleeves 26 are spaced vertically along the outer side of the main pipe 21. Each sleeve 26 has a secondary pipe 22 on its outer side. The multiple secondary pipes 22 allow concrete to enter the pouring cavity evenly during concrete pouring, resulting in good shear wall forming effect, a large amount of concrete poured per unit time, fast pouring speed, and high pouring efficiency. At the same time, the multiple secondary pipes 22 can more stably connect the main pipe 21 to the formwork body 10, resulting in higher structural stability.

[0046] In one embodiment, a diffusion box 40 is provided between the main pipe 21 and the corresponding short side mold 12. The diffusion box 40 has multiple inlets on the side near the main pipe 21 and multiple outlets on the side near the corresponding short side mold 12. The number of secondary pipes 22 is consistent with the number of inlets and corresponds one-to-one. The second end of the secondary pipe 22 is connected to the corresponding inlet. Each outlet is connected to the casting cavity through a conveying pipe 50.

[0047] Specifically, such as Figure 1 and Figure 3 As shown, when pouring concrete, the concrete enters the main pipe 21 and then enters the distribution box through multiple secondary pipes 22 on the main pipe 21. It then enters the pouring cavity through multiple conveying pipes 50 spaced apart in the vertical direction on the distribution box, so that the concrete can enter the pouring cavity more dispersedly, the pouring speed is faster, the pouring efficiency is higher, and the molding effect is better.

[0048] In one embodiment, the bottom mold 13 has two slots 131 formed at both ends along the lateral direction, and the bottom ends of the two short side molds 12 are respectively inserted into the two slots 131.

[0049] Specifically, such as Figure 1 and Figure 4 As shown, when assembling the main body of the template 10, it is only necessary to insert the two short side molds 12 into the corresponding two slots 131 respectively. The short side molds 12 can be quickly and accurately installed on the bottom mold 13. The installation is simple, accurate and fast.

[0050] In one embodiment, the verticality correction device 30 includes a dial 31, a suspension line 36, and a counterweight 37. The dial 31 is mounted on the corresponding long side mold 11. The dial 31 has a scale area 34 formed by scale lines 35. The upper end of the suspension line 36 is mounted on the dial 31 and passes through the scale area 34.

[0051] Specifically, such as Figure 1 and Figure 2As shown, a scale 31 is installed on a long side mold 11 on the front side, and the scale 31 has a scale area 34. The scale area 34 on the scale 31 has multiple scale lines 35. A counterweight 37 is installed on the scale 31 via a suspension line 36, which passes through the scale area 34 and is measured by comparing it with the multiple scale lines 35. When installing the shear wall, the operator can directly measure the verticality of the prefabricated shear wall installation by observing the relationship between the position of the projection of the suspension line 36 on the scale area 34 and the position of the scale lines 35. If the projected position does not coincide with the vertical scale line 35, the shear wall assembly template 100 is adjusted until the projected position coincides with the vertical scale line 35. Verticality can be measured simultaneously with the installation of the prefabricated shear wall, which is convenient and eliminates the need for personnel to repeatedly climb ladders to measure, saving manpower and ensuring safety by avoiding work at heights.

[0052] In one embodiment, the dial 31 includes a mounting block 33 and a dial body 32. The mounting block 33 and the dial body 32 are both mounted on the corresponding long side mold 11, and the mounting block 33 is located above the dial body 32. The dial body 32 is annular, and a scale area 34 is formed on the side of the dial body 32 away from the template body 10. Scale lines 35 are engraved along the circumferential edge of the dial body 32 in the scale area 34. The upper end of the suspension line 36 is mounted on the mounting block 33.

[0053] Specifically, such as Figure 1 and Figure 2 As shown, the dial 31 includes a mounting block 33 and a dial body 32. The dial body 32 and the mounting block 33 are mounted on the front long template, with the mounting block 33 positioned above the dial body 32. The mounting block 33 protrudes in a direction away from the main support of the template. The suspension line 36 is mounted on the mounting block 33 and passes through the scale area 34. The suspension line 36 and the dial 31 are spaced apart in the front-to-back direction to avoid interference from the dial 31, ensuring high accuracy. When adjusting the verticality of the shear wall, the suspension line 36 moves in a circular motion around the mounting block 33 under the action of the bottom counterweight 37. Therefore, the dial body 32 is circular, and the scale area 34 is set along the circumference of the dial 31 to match the trajectory of the suspension line 36, making it easier to observe the verticality of the shear wall.

[0054] In one embodiment, the inner wall of the disc 32 forms an inclined surface 38, which is inclined outward in a direction away from the mold body, and the scale line 35 is engraved on the inclined surface 38.

[0055] Specifically, such as Figures 1 to 2 As shown, the inner wall of the annular disc 32 has an inclined surface 38. The inclined surface 38 is inclined outward in the forward direction. The scale line 35 is engraved along the inclined surface 38 to form an inclined scale area 34. The inclined scale area 34 is easy to observe and the observation is clearer.

[0056] In one embodiment, the mounting block 33 is rotatably mounted on the corresponding long side mold 11 via a longitudinally arranged pivot, and the upper end of the suspension line 36 is wound around the mounting block 33.

[0057] Specifically, the mounting block 33 is mounted on the front long side mold 11 via a pivot that can rotate in the front-back direction. By rotating the mounting block 33, the suspension line 36 is wound around the mounting block 33, which facilitates the winding and unwinding of the suspension line 36.

[0058] In one embodiment, a handle 331 is mounted on the end of the mounting block 33 furthest from the template body 10. For example... Figures 1 to 2 As shown, the mounting block 33 can be rotated by rotating the shaft via the handle 331, making it easy to operate.

[0059] In one embodiment, the mounting block 33 is covered by the protective shell 332, and a wire-passing opening is formed at the bottom of the protective shell 332. The protective shell 332 and the mounting block 33 form a receiving space for accommodating the suspension wire 36, through which the suspension wire 36 passes.

[0060] Specifically, such as Figures 1 to 2 As shown, the mounting block 33 is covered with a protective shell 332. By rotating the pivot, the suspension wire 36 is wound around the mounting block 33 and housed in the accommodating space, which can protect the suspension wire 36 and make it highly durable.

[0061] In one embodiment, the counterweight 37 is conical in shape, with its tip pointing downwards. Specifically, as shown... Figures 1 to 2 As shown, the conical counterweight 37 can reduce the swaying of the suspension line 36 during use and is easy to observe.

[0062] In one embodiment, the casting fitting includes a main pipe 21 and a secondary pipe 22. The main pipe 21 is arranged vertically, one end of the secondary pipe 22 communicates with the cavity of the main pipe 21, and the other end of the secondary pipe 22 communicates with the casting cavity. Specifically, as shown... Figures 1 to 2 As shown, the main pipe 21 is set near the short side mold 12 on the left side along the vertical direction. The cavity of the main pipe 21 is connected to the pouring cavity through the secondary pipe 22. Concrete is poured into the pouring cavity through the main pipe 21. The design is reasonable and the pouring is convenient.

[0063] In one embodiment, there are multiple secondary tubes 22, which are arranged at vertical intervals. Specifically, as shown... Figures 1 to 2 As shown, multiple secondary pipes 22 are arranged in the vertical direction, and concrete can be poured more evenly through the multiple secondary pipes 22 into the pouring cavity.

[0064] In one embodiment, a plurality of rebar positioning holes 60 are spaced laterally on the top mold 141. Specifically, as shown... Figures 1 to 2As shown, multiple rebar positioning holes 60 can be used to engage with the rebars on the prefabricated shear wall, enabling the prefabricated shear wall to be accurately installed in the casting cavity. Positioning is simple and installation is convenient.
