Description

Technical Field

[0001] The present application relates to the technical field of prefabricated concrete construction, and in particular to a core mold of a composite shear wall formwork, a composite shear wall formwork, and a manufacturing method thereof. Background Art

[0002] In recent years, in order to alleviate problems such as labor shortage, short construction period, low-carbon and environmental protection, my country has begun to promote prefabricated buildings. As an emerging green, environmentally friendly and energy-saving building, it has the advantages of fast construction speed, little impact from climatic conditions, saving on-site labor, and improving building quality. It has become a new direction for the development of the future construction industry.

[0003] The fully prefabricated assembled concrete shear wall has a large deadweight, and requires high performance of equipment for transportation and lifting. The construction steps during on-site assembly are cumbersome and the construction quality is difficult to detect.

[0004] Prefabricated composite shear walls are usually composed of two layers of prefabricated reinforced concrete slabs connected by trusses or connectors to form a wall panel component with a middle cavity. After on-site installation, concrete is poured to fill the middle cavity to form a concrete wall panel. Currently, prefabricated composite shear walls have begun to be used in engineering. Compared with fully prefabricated concrete shear walls, prefabricated composite shear walls have the advantages of light weight, low processing and installation precision requirements, and strong fault tolerance. It is a promising prefabricated concrete structural system.

[0005] As the template of the prefabricated superimposed shear wall, the superimposed shear wall formwork is an important component. In the production process of the superimposed shear wall formwork, an intermediate cavity needs to be formed, which requires the use of a core mold. Currently, in the production process of the superimposed shear wall formwork, there are still problems such as cumbersome steps and low production efficiency. In addition, in the construction application of prefabricated superimposed shear walls, there are also problems such as difficulty in ensuring the quality of steel bar connections, difficulty in concrete pouring and vibration, and the inability of the superimposed shear wall formwork and cast-in-place concrete to be superimposed on each other. These are not conducive to the normal development of the construction period and bring hidden dangers to structural safety. Summary of the invention

[0006] In order to improve the production efficiency of assembled composite shear walls and reduce the production cost of composite shear wall formwork, the present application provides a core mold of a composite shear wall formwork, a composite shear wall formwork and a manufacturing method thereof.

[0007] In the first aspect, the core mold of a composite shear wall formwork provided by the present application adopts the following technical solution: A core mold of a composite shear wall formwork, comprising a first transverse movement module and a second transverse movement module arranged opposite to each other at an interval, wherein both sides of the first transverse movement module and the sides directly facing the second transverse movement module are connected with a plane partition; The first transverse movement module, the second transverse movement module and the two planar partitions together enclose a mounting cavity; A vertical movement module is arranged in the installation cavity and the vertical movement module is located between the first horizontal movement module and the second horizontal movement module; A plurality of first mechanical links are arranged between the vertical movement module and the first transverse movement module, and the two ends of each of the first mechanical links are respectively hinged to the vertical movement module and the first transverse movement module; a plurality of second mechanical links are arranged between the vertical movement module and the second transverse movement module, and the two ends of each of the second mechanical links are respectively hinged to the vertical movement module and the second transverse movement module.

[0008] By adopting the above technical solution and using external force to move the vertical displacement module axially, the entire core mold can be easily and quickly converted between the open and closed states, thereby realizing convenient assembly and disassembly of the core mold, effectively realizing the hole-forming process of the composite shear wall formwork, and improving the efficiency of demolding the composite shear wall formwork, greatly improving the production efficiency of the composite shear wall formwork, and reducing the production cost of the composite shear wall formwork. At the same time, the core mold design makes the through vertical holes formed inside the formwork more regular, which is helpful for the quality control of subsequent concrete pouring, reduces the difficulty of vibration, ensures the density and uniformity of the concrete, and ensures the molding quality and structural stability of the composite shear wall formwork.

[0009] Optionally, the first transverse movement module and the second transverse movement module both include an arc-shaped plate and a rectangular frame, one end of the rectangular frame is fixedly connected to the inner middle part of the arc-shaped plate, and the arc-shaped plate opening of the first transverse movement module is arranged opposite to the arc-shaped plate opening of the second transverse movement module; The plane partition is made of a rigid hard plate, one side of the plane partition has a first step notch, the other side of the plane partition has a second step notch, the side of the arc plate has a third step notch facing the installation cavity, the two sides of the plane partition are connected to the arc plate through the first step notch, the second step notch and the third step notch, and a flexible partition is provided between the plane partition and the arc plate; A connecting rod mechanism is arranged between the vertical moving module and the planar partitions on both sides. When the vertical moving module moves axially, the vertical moving module drives the two planar partitions on both sides thereof to move away from or towards each other through the connecting rod mechanism.

[0010] By adopting the above technical solution, the plane partition is made of a rigid hard plate, which is more durable, has high support strength, is not easy to break, and can be reused many times. When the vertical movement module moves axially, it can not only drive the first horizontal movement module and the second horizontal movement module to move closer to each other, but also drive the two plane partitions on both sides to move closer to each other through the connecting rod mechanism, so as to realize the folding of the entire core mold conveniently and quickly, and improve the demolding efficiency of the composite shear wall formwork.

[0011] Optionally, as another solution, the first transverse movement module and the second transverse movement module both include an arc-shaped plate and a rectangular frame, one end of the rectangular frame is fixedly connected to the inner middle part of the arc-shaped plate, and the arc-shaped plate opening of the first transverse movement module is arranged opposite to the arc-shaped plate opening of the second transverse movement module; The plane partition is made of flexible mold cloth, and the plane partition is connected to the side of the arc plate. The first mechanical connecting rod and the second mechanical connecting rod are connected to the side of the rectangular frame.

[0012] By adopting the above technical scheme, the core mold structure of the composite shear wall formwork is reasonably designed, and the hole-forming accuracy and stability of the formwork are improved. The combined structure of the arc plate and the rectangular frame makes the core mold more stable during the expansion and contraction process, avoiding the hole-forming error caused by structural instability. At the same time, the plane partition is connected to the side of the arc plate, which ensures the sealing and integrity of the core mold under different working conditions and prevents leakage of concrete slurry. The first mechanical connecting rod and the second mechanical connecting rod are connected to the side of the rectangular frame, which enhances the overall rigidity of the core mold and ensures the stability and reliability of the formwork during the casting process. The plane partition made of flexible mold cloth is easy to deform and easy to demold. At the same time, it will not interfere with the contraction of the first transverse displacement module and the second transverse displacement module, and is easy to use.

[0013] Optionally, there are at least three pairs of the first mechanical links and the second mechanical links, which are spaced apart along the length direction of the vertical movement module; the two first mechanical links in each pair of the first mechanical links are respectively arranged on both sides of the rectangular frame of the vertical movement module and the first transverse movement module, and the rectangular frames of the vertical movement module and the first transverse movement module are provided with a first pair of through bolts for hingedly connecting the ends of the first mechanical links; the two second mechanical links in each pair of the second mechanical links are respectively arranged on both sides of the rectangular frame of the vertical movement module and the second transverse movement module, and the rectangular frames of the vertical movement module and the second transverse movement module are provided with a second pair of through bolts for hingedly connecting the ends of the second mechanical links.

[0014] By adopting the above technical solution, the multiple pairs of mechanical connecting rods and their reasonable distribution enable the core mold to evenly transmit force at different positions, ensuring that the core mold is stable and reliable during the process of opening and closing, and avoiding damage caused by local stress concentration. The first mechanical connecting rod and the second mechanical connecting rod are respectively hinged to the rectangular frame of the vertical movement module and the horizontal movement module, and are fixed by through bolts, which ensures the smoothness and durability of the first mechanical connecting rod and the second mechanical connecting rod during movement. This design not only improves the service life of the core mold, but also enhances its operational convenience and reliability in practical applications.

[0015] Optionally, a first limit stopper corresponding to the first mechanical link is arranged on the side surface of the rectangular frame of the first transverse movement module, the first limit stopper is located on one side of the corresponding first through bolt, the length direction of the first limit stopper is arranged along the width direction of the plane partition, and when the first mechanical link is swung to the point where its length direction is consistent with the width direction of the plane partition, the side edge of the first mechanical link abuts against the side edge of the corresponding first limit stopper; A second limit block corresponding to the second mechanical link is arranged on the side of the rectangular frame of the second transverse movement module, and the second limit block is located on the corresponding side of the second through bolt. The length direction of the second limit block is arranged along the width direction of the planar partition. When the second mechanical link swings to the point where its length direction is consistent with the width direction of the planar partition, the side edge of the second mechanical link abuts against the side edge of the corresponding second limit block.

[0016] By adopting the above technical solution, the first limit baffle and the second limit baffle can effectively limit the maximum swing angle of the first mechanical link and the second mechanical link, ensuring that the first mechanical link and the second mechanical link stop moving when they quickly reach the predetermined position, which not only improves the work efficiency, but also prevents structural damage caused by excessive expansion, and improves the reliability and safety of the core mold during the work process. In addition, the provision of the first limit baffle and the second limit baffle can also ensure that the core mold is smoothly reset when it shrinks, thereby ensuring that the core mold can be smoothly pulled out of the concrete, improving the quality and efficiency of hole formation.

[0017] Optionally, the first limit baffle and the second limit baffle both have a clearance groove in the middle of their side edges, and the first mechanical link and the second mechanical link are connected to the ends of the rectangular frame body to form arc-shaped end faces, and when the first mechanical link and the second mechanical link swing, the arc-shaped end faces of the two can swing into the corresponding clearance grooves.

[0018] By adopting the above technical solution, the clearance grooves set in the middle of the side edges of the first limit baffle and the second limit baffle can ensure that the arc-shaped end faces of the first mechanical connecting rod and the second mechanical connecting rod can smoothly enter the corresponding clearance grooves during the swinging process, avoiding the mechanical connecting rod and the limit baffle from colliding and causing damage, and meeting the requirements of the rotation radius of the mechanical connecting rod. This not only improves the stability and reliability of the mechanical core mold, but also extends its service life. In addition, this design makes the mechanical connecting rod smoother during the swinging process, reduces resistance, and thus improves the efficiency of the opening and closing of the core mold.

[0019] Optionally, a plurality of convex rib structures for enhancing the internal friction strength of the concrete hole are arranged on the outer side of the arc-shaped plate.

[0020] By adopting the above technical solution, the stability of concrete hole formation can be significantly improved, ensuring the molding quality of the formwork and the reliability of subsequent use. The rib structure greatly increases the bonding force between the concrete and the formwork, which helps to improve the overall mechanical properties of the composite shear wall.

[0021] Optionally, the first transverse movement module and the second transverse movement module are symmetrically arranged, the length of the vertical movement module is greater than the length of the first transverse movement module and the second transverse movement module, and both ends of the vertical movement module extend out of the installation cavity.

[0022] By adopting the above technical solution, the overall balance and stability of the core mold are guaranteed, and displacement or tilting during use is avoided. The length of the vertical movement module is greater than the length of the first horizontal movement module and the second horizontal movement module, and both ends extend out of the installation cavity, ensuring that the vertical movement module has sufficient travel space during the movement process, thereby realizing the smooth opening and closing of the core mold, and improving the reliability and efficiency of mold shell production. At the same time, this design is also conducive to manual operation and convenient for the installation and removal of the core mold.

[0023] Optionally, the cross-section of the vertical movement module is a hollow rectangle, one end of the vertical movement module is provided with a hammer structure, and the other end of the vertical movement module is provided with a push-pull structure.

[0024] By adopting the above technical solution, the cross-section of the vertical moving module is designed as a hollow rectangle, which can reduce the overall weight of the core mold, facilitate the operator to carry and install, and also save costs. The hammer structure and push-pull structure set at the end of the vertical moving module can easily apply external force during the process of opening or closing the core mold, quickly and accurately deform the core mold, improve work efficiency, and ensure the service life of the core mold.

[0025] In the second aspect, the composite shear wall formwork provided by the present application adopts the following technical solution: A composite shear wall formwork is made by using the core mold, the composite shear wall formwork comprises a first concrete slab and a second concrete slab arranged in parallel and spaced apart, a plurality of longitudinal ribs are arranged between the first concrete slab and the second concrete slab; two adjacent longitudinal ribs and the first concrete slab and the second concrete slab are surrounded to form a through vertical hole, the through vertical hole is formed by the core mold; Steel mesh is arranged inside the first concrete slab and the second concrete slab, and tension bars are arranged inside the longitudinal ribs.

[0026] The composite shear wall formwork in the present application solves the problems of difficulty in pouring concrete of prefabricated shear walls and composite stress defects, realizes the permanent structure integration of the formwork and the concrete load-bearing structure, and can effectively improve the pouring quality of concrete. A plurality of through vertical holes are arranged in the composite shear wall formwork, the thickness of the formwork is small and a wire mesh is arranged inside, which enhances the overall rigidity and stability of the formwork, improves the structural safety of the composite shear wall, and has a low cost.

[0027] In a third aspect, the present application provides a method for manufacturing a composite shear wall formwork using the following technical solution: A method for manufacturing a composite shear wall formwork, using the core mold to manufacture the composite shear wall formwork, the manufacturing method comprises the following steps: S1: Setting up the table formwork: Setting up two parallel and spaced formworks, and tying the wire mesh and tie bars between the two formworks; S2: Setting the core mold: a plurality of sets of core molds are set between the two templates according to the set middle cavity position of the composite shear wall formwork. When setting the core mold, pressure is applied to one end of the vertical movement module to move the vertical movement module toward the other end along its length direction, driving the first mechanical connecting rod and the second mechanical connecting rod to swing and deform; and then the first horizontal movement module and the second horizontal movement module are pushed away from each other to form the core mold in an open state; S3: Pouring: pouring concrete into the table form and vibrating it; S4: demolding: after the concrete strength is improved, the core mold and the table mold are removed; when the core mold is removed, a pulling force is applied to one end of the vertical moving module and a pressure is applied to the other end, so that the vertical moving module moves in the opposite direction along its length, driving the first mechanical connecting rod and the second mechanical connecting rod to swing and deform; then the first transverse moving module and the second transverse moving module are pushed closer to each other to form a core mold in a folded state; at this time, the entire core mold is pulled out along the length direction of the mold shell to realize the separation of the core mold and the concrete mold shell to form a hole.

[0028] By adopting the above technical scheme, an efficient hole-forming process for the composite shear wall formwork is realized, the production efficiency of the composite shear wall formwork is improved, the production cost is reduced, and the quality and reliability of the formwork are ensured.

[0066] Reference Figure 2 , Figure 3 and Figure 8 As shown, in the present application, a first limit baffle 13 corresponding to the first mechanical link 60 is welded and fixedly connected on the side surface of the rectangular frame 12 of the first transverse movement module 10, and the first limit baffle 13 is located on one side of the corresponding first through bolt 80. The length direction of the first limit baffle 13 is arranged along the width direction of the plane partition 30. When the first mechanical link 60 swings to the point where its length direction is consistent with the width direction of the plane partition 30, the side edge of the first mechanical link 60 abuts against the side edge of the corresponding first limit baffle 13. On the side; the second limit baffle 21 corresponding to the second mechanical link 70 is welded and fixed on the side of the rectangular frame 12 of the second transverse module 20.

When the second mechanical link 70 swings to the point where its length direction is consistent with the width direction of the plane partition 30, the side of the second mechanical link 70 abuts against the side of the corresponding second limit baffle 21. The first limit baffle 13 and the second limit baffle 21 can effectively limit the maximum swing angle of the first mechanical link 60 and the second mechanical link 70, ensuring that the first mechanical link 60 and the second mechanical link 70 stop moving when they quickly reach the predetermined position, which not only improves the work efficiency, but also prevents structural damage caused by excessive expansion, and improves the reliability and safety of the core mold during operation. In addition, the provision of the first limit baffle 13 and the second limit baffle 21 can also ensure that the core mold is smoothly reset when it shrinks, thereby ensuring that the core mold can be smoothly pulled out of the concrete, thereby improving the quality and efficiency of hole formation.

[0067] Reference Figure 8As shown, in order to meet the requirements of the rotation radius of the first mechanical link 60 and the second mechanical link 70, a clearance groove 131 is opened in the middle of the side of the first limit block 13 and the second limit block 21, and a stiffening rib 132 is provided in the middle of the other side of the first limit block 13 and the second limit block 21. The stiffening rib 132 is triangular and fixedly connected to the side of the rectangular frame 12 of the first transverse movement module 10 and the side of the rectangular frame 12 of the second transverse movement module 20.

When the first mechanical link 60 and the second mechanical link 70 swing, the arc-shaped end faces of the two can swing into the corresponding clearance groove 131, so that the arc-shaped end faces of the first mechanical link 60 and the second mechanical link 70 can smoothly enter the corresponding clearance groove 131 during the swinging process, avoiding the collision between the mechanical link and the limit baffle and causing damage, which not only improves the stability and reliability of the mechanical core mold, but also extends its service life. In addition, this design makes the mechanical link smoother during the swinging process, reduces resistance, and thus improves the efficiency of the opening and closing of the core mold.

[0068] Reference Fig. 9 and Fig.10 As shown, a hammer structure 51 is provided at one end of the vertical moving module 50, and the hammer structure 51 can be a T-shaped iron block. The vertical rod end of the hammer structure 51 is embedded in the vertical moving module 50 and is fixedly connected to the vertical moving module 50.

The boss 522 abuts against the end face of the vertical moving module 50, and a pull ring 523 is fixedly provided on the outer side of the boss 522. The hammer structure 51 and the push-pull structure 52 provided at the end of the vertical moving module 50 can conveniently apply external force during the process of opening or closing the core mold, quickly and accurately deform the core mold, improve work efficiency, and ensure the service life of the core mold.

[0069] Reference Fig.11 and Fig.12As shown, the outer side of the arc plate 11 is provided with a plurality of convex rib structures 111 for enhancing the internal friction strength of the concrete hole. The convex rib structures 111 can significantly improve the stability of the concrete hole, ensure the molding quality of the formwork and the reliability of subsequent use. The convex rib structures 111 greatly increase the bonding force between the concrete and the formwork, which helps to improve the overall mechanical properties of the composite shear wall.

[0070] The implementation principle is as follows: Fig.13 , Fig.14 and Fig.15 As shown, when the vertical moving module 50 moves axially, it can not only drive the first horizontal moving module 10 and the second horizontal moving module 20 to move closer to each other, but also drive the two planar partitions 30 on both sides thereof to move closer to each other through the connecting rod mechanism 1000, thereby realizing the folding of the entire core mold conveniently and quickly, and improving the demolding efficiency of the composite shear wall formwork. The planar partition 30 is made of a rigid hard plate, which is more durable, has a high support strength, is not easy to be damaged, and can be reused many times. The flexible interlayer 900 is arranged on the step surfaces of the first step notch 31, the second step notch 32 and the third step notch 114. The setting of the flexible interlayer 900 not only improves the sealing of the connection between the plane partition 30 and the arc plate 11, but also the flexible interlayer 900 can produce a certain deformation. When the vertical movement module 50 drives the first transverse movement module 10 and the second transverse movement module 20 to move closer to each other, the flexible interlayer 900 can be squeezed to prevent it from being stuck. When the two plane partitions 30 move closer to each other for a certain distance, they can completely detach from the arc plate 11 of the first transverse movement module 10 and the second transverse movement module 20, and the movement of the first transverse movement module 10, the second transverse movement module 20 and the two plane partitions 30 can be carried out smoothly, thereby realizing the folding and folding of the entire core mold.

[0071] In the present application, by using external force to make the vertical displacement module 50 move axially, the entire core mold can be easily and quickly converted between the two states of expansion and contraction, so that the core mold can be conveniently assembled and disassembled, and the hole-forming process of the composite shear wall formwork can be effectively realized, and the efficiency of demolding the composite shear wall formwork can be improved, which greatly improves the production efficiency of the composite shear wall formwork and reduces the production cost of the composite shear wall formwork. At the same time, the core mold design makes the through vertical hole 400 formed inside the formwork more regular, which is helpful for the quality control of subsequent concrete pouring, reduces the difficulty of vibration, ensures the density and uniformity of the concrete, and ensures the molding quality and structural stability of the composite shear wall formwork.

[0072] The core mold structure of the composite shear wall formwork in the present application is reasonably designed, which improves the hole-forming accuracy and stability of the formwork. The combined structure of the arc plate 11 and the rectangular frame 12 makes the core mold more stable during the expansion and contraction process, avoiding the hole-forming error caused by structural instability. At the same time, the plane partition 30 is connected to the side of the arc plate 11, ensuring the sealing and integrity of the core mold under different working conditions, and preventing the leakage of concrete slurry. The first mechanical connecting rod 60 and the second mechanical connecting rod 70 are connected to the side of the rectangular frame 12, which enhances the overall rigidity of the core mold and ensures the stability and reliability of the formwork during the casting process.

[0073] The multiple pairs of mechanical links and their reasonable distribution in the present application enable the core mold to evenly transmit force at different positions, ensuring that the core mold is stable and reliable during the process of opening and closing, and avoiding damage caused by local stress concentration. The first mechanical link 60 and the second mechanical link 70 are respectively hinged to the rectangular frame 12 of the vertical movement module 50 and the horizontal movement module, and are fixed by through bolts, ensuring the smoothness and durability of the first mechanical link 60 and the second mechanical link 70 during movement. This design not only improves the service life of the core mold, but also enhances its operational convenience and reliability in practical applications.

[0074] Example 2 Reference Fig.16 As shown, this embodiment is substantially the same as embodiment 1, except that, in this embodiment, the connecting rod mechanism 1000 includes a first mounting seat 1001 fixed on the side of the vertical movement module 50 facing the first transverse movement module 10 and / or the second transverse movement module 20, and a second mounting seat 1002 fixed on the side of the two planar partitions 30 facing the vertical movement module 50; a connecting rod 1005 is arranged between the first mounting seat 1001 and the second mounting seat 1002, and both ends of the connecting rod are pivotally connected to the first mounting seat 1001 and the second mounting seat 1002 respectively; this facilitates spatial layout, and when two groups of connecting rods 1005 are arranged side by side, the two groups of connecting rods 1005 are farther apart and the force is more balanced.

[0075] Example 3 Reference Fig.17 and Fig.18 As shown, this embodiment is substantially the same as embodiment 1 or embodiment 2, except that in this embodiment, the plane partition 30 is made of flexible mold cloth, for example, the plane partition 30 can be made of high-strength nylon cloth or polyester fiber cloth, these materials have strong rigidity, and no obvious vertical deformation under a uniform load of 1000N / m². The two sides of the plane partition 30 are directly connected to the side edges of the arc plate 11, for example, rivets and strips can be used to fix the two. Fig.19 and Fig. 20As shown, when the first transverse moving module 10 and the second transverse moving module 20 move away from each other under the drive of the vertical moving module 50, the two opposite arc-shaped plates 11 can pull the two sides of the plane partition 30 to make it tight, thereby forming a barrier plate. When the first transverse moving module 10 and the second transverse moving module 20 move closer to each other under the drive of the vertical moving module 50, the lateral deformation of the plane partition 30 can facilitate demoulding without affecting the relative movement between the first transverse moving module 10 and the second transverse moving module 20. In the present application, rough spots can be set on the contact surface between the plane partition 30 and the concrete to increase the friction strength inside the concrete vertical hole. In this way, the overall structure is simpler and the cost is lower.

[0076] Example 4 Reference Fig.21 and Fig. 22 As shown, this embodiment is substantially the same as the embodiment 3, except that in this embodiment, the arc plate 11 is further improved, and arc extension blocks 112 are detachably connected to both sides of the arc plate 11, and the arc curvature of the arc extension block 112 is the same as that of the arc plate 11, and matching step grooves 113 are provided between the two sides of the arc plate 11 and the side edges of the arc extension block 112. After the arc extension block 112 is installed on the side edge of the arc plate 11, the outer side surface of the arc extension block 112 is smoothly connected with the outer side surface of the arc plate 11. The arc extension block 112 and the arc plate 11 can be connected by bolt connection or clamping.

[0077] By optimizing the structure of the arc plate 11, the core mold can be further disassembled according to the production environment of the concrete composite shear wall formwork, and the size of the core mold can be further expanded and contracted, thereby meeting the requirements of a variety of different use environments and improving versatility.

Tie rods 800 are arranged in the longitudinal ribs 300, and the arrangement form of the tie rods 800 includes but is not limited to an X-shaped-plum blossom arrangement. The diameter of the tie rods 800 is between 4mm and 10mm; a hanging piece 700 is also arranged on the longitudinal rib 300 to facilitate the lifting and transportation of the formwork.

[0079] The side of the formwork is a half-hole form without reinforcement. When two adjacent superimposed shear wall formworks are connected, the horizontal direction is connected by a close joint, and a non-contact wire mesh 500 is installed inside. After pouring concrete, the superimposed shear wall joint connection can be realized. Since the horizontal connection joint cavity of the concrete superimposed formwork is large and there is no reinforcement to affect the concrete pouring, the construction quality of the prefabricated shear wall can be effectively improved.

[0080] The composite shear wall formwork in the present application solves the problems of difficulty in pouring concrete of the assembled shear wall and the defects of composite stress, realizes the permanent structure integration of the formwork and the concrete load-bearing structure, and can effectively improve the pouring quality of concrete.
