Description

Technical Field

[0001] The invention belongs to the field of building technology, relates to a prefabricated shear wall, and in particular to a prefabricated hollow composite shear wall with vertical steel bars of rear-penetrating edge components. Background Art

[0002] After nearly ten years of development, my country has formed two major prefabricated integral shear wall structure systems: fully prefabricated shear wall structure and composite shear wall structure. Thanks to the advantages of low cost of overlapping steel bar connection, easy control of connection quality, light weight of prefabricated wall and high efficiency of on-site installation, composite shear walls such as double-sided composite shear wall and prefabricated hollow slab shear wall have developed rapidly in recent years and achieved good social and economic benefits. However, engineering practice shows that the existing composite shear wall structure system still has common problems such as complex prefabricated wall production equipment, high threshold of production technology management, large fixed investment in production lines and difficulty in pre-embedding of electromechanical points. It cannot be directly produced on existing production lines such as fixed mold production lines and flat mold assembly lines in domestic prefabricated component factories with large quantities and wide coverage, which restricts its application and development. At the same time, restricted by the production process and prefabricated wall structure, it is difficult to achieve integrated construction of structure, insulation and decoration for the prefabricated exterior walls of some composite shear wall structure systems, which cannot meet the actual needs of current prefabricated projects and needs further optimization and improvement.

[0003] Previously, I have submitted a patent application entitled "A prefabricated hollow composite shear wall based on flat mold production and steel bar overlap" to the State Patent Office. The above patent discloses a prefabricated hollow composite shear wall based on flat mold production and steel bar overlap, which solves the shortcomings of the current composite shear wall structure system and can realize the integrated construction of prefabricated exterior wall structure, insulation, and decoration. Based on the above patent, the present invention intends to optimize and innovate the edge component structure of the prefabricated hollow composite shear wall, and adopts the vertical force-bearing steel bars of the edge components to avoid the vertical steel bars of the prefabricated wall edge components from coming out, so as to realize the universalization and standardization of the prefabricated wall side molds, which is beneficial to cost control and finished product protection. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings of the existing composite shear wall technology system, the purpose of the present invention is to provide a prefabricated hollow composite shear wall with vertical steel bars of the edge components inserted later, which integrates the advantages of low connection cost of the composite shear wall, easy control of connection quality, light weight of the prefabricated wall and high efficiency of on-site installation, and adopts a fixed pipe to form a vertical hole in the prefabricated wall at one time. The prefabricated wall production does not need to use a special hole-forming equipment, and can be produced by the existing production lines such as the fixed mold production line and the flat mold flow production line of the domestic prefabricated component factory with large quantity and wide application, avoiding the investment of new fixed equipment, and the prefabrication production links are few and the production efficiency is high, which can realize the prefabrication of the prefabricated exterior wall structure, insulation and decoration. In addition, the vertical steel bars and vertical distribution steel bars of the edge components of the prefabricated wall do not extend out of the prefabricated wall, and the side molds are not opened during the production of the prefabricated wall, which can realize the universalization and standardization of the mold, which is helpful to improve the production efficiency of the prefabricated wall and reduce the comprehensive cost of the prefabricated wall; the vertical steel bars of the prefabricated wall do not extend outward, which can avoid the bending of the steel bars during transportation, which is conducive to the protection of the finished product and on-site hoisting.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A prefabricated hollow composite shear wall with vertical reinforcement of edge components inserted later comprises a prefabricated concrete wall with vertical holes, vertical reinforcement of large-diameter edge components inserted into the vertical holes of edge components, additional connecting reinforcement arranged in the vertical holes of the wall body, and post-cast concrete in the vertical holes. The prefabricated hollow composite shear wall comprises an edge component part and a wall body part, and a vertical hole is formed inside the prefabricated wall by pouring in one time using a fixed pipe, without the need for a special hole-forming device. The structure of the wall body part is consistent with the invention and utility model patent applied by the author, entitled "A prefabricated hollow composite shear wall based on flat mold production and reinforcement overlap". In the edge component part, only vertical structural reinforcement and stirrups are arranged in the edge component of the prefabricated wall, and large-diameter vertical reinforcement of edge components is used to replace multiple small-diameter vertical reinforcement of edge components of traditional shear walls, and is inserted into the vertical hole of the edge component at the construction site. A hand hole is set at the root of the prefabricated wall to realize the threaded joint connection of the vertical reinforcement in the vertical hole. The vertical structural steel bars of the edge components of the prefabricated wall and the vertical distribution steel bars of the wall body do not extend out of the top and bottom surfaces of the prefabricated wall. No holes are opened in the corresponding side molds during the prefabricated wall production stage, which can achieve standardization and universalization of the molds, and is beneficial to cost control and protection of finished products.

[0007] The present invention discloses a prefabricated hollow composite shear wall with post-pierced vertical reinforcement of edge members, wherein only vertical structural reinforcement and stirrups are arranged in the edge members of the prefabricated wall, and the structure of the vertical structural reinforcement and stirrups is consistent with that of ordinary cast-in-place shear walls; the vertical structural reinforcement is arranged outside the vertical hole range of the edge member and does not extend out of the prefabricated wall, the vertical structural reinforcement only forms a reinforcement skeleton with the stirrups of the edge member and does not participate in the force calculation; large-diameter vertical stress-bearing reinforcement of edge members is used to replace multiple small-diameter vertical reinforcement of edge members of traditional shear walls, and after the on-site prefabricated wall is installed, large-diameter vertical stress-bearing reinforcement of edge members is inserted in the vertical hole of the edge member, and an installation hand hole is reserved at the root of the edge member of the prefabricated wall, and a steel bar threaded joint is used in the installation hand hole to realize the connection of the vertical stress-bearing reinforcement of the edge members of the upper and lower walls.

[0008] The vertical holes of the edge members are formed by using shaped pipes. The shaped pipes have the same cross-section from top to bottom and can be circular, rectangular or other cross-sectional forms as needed. A vertical force-bearing steel bar of the edge member is arranged in each shaped pipe. The dimensions of the shaped pipes along the wall thickness and wall length directions should not be less than 80 mm to ensure the pouring quality of the post-cast concrete in the vertical holes.

[0009] The vertical stress-bearing steel bars of the large-diameter edge member are arranged along the center line of the wall thickness. On the basis of meeting the installation of the threaded joint in the hand hole and the pouring of post-cast concrete in the vertical hole, the vertical stress-bearing steel bars of the edge member are arranged on one side in the vertical hole of the edge member to reduce the size of the vertical hole of the edge member, facilitate the cost control of the steel bar arrangement and the standardized pipes used for edge member hole forming; the vertical stress-bearing steel bars of the large-diameter edge member participate in the structural force calculation, and the reinforcement area should meet the requirements for the compressive bearing verification of the positive section of the shear wall. It can also replace multiple small-diameter edge member vertical steel bars of the traditional shear wall according to the principle of equal area replacement of steel bars of the same strength grade.

[0010] The hand hole for installing the root of the prefabricated wall edge component is formed by using a fixed mold, and the size should meet the installation and construction requirements of the vertical force-bearing steel bar threaded joint of the edge component; after the hand hole is reserved for installation, the concrete wall thickness around the hand hole should not be less than 40mm to prevent the concrete wall from cracking during the pouring of concrete in the vertical hole on site; within the range of the hand hole, the vertical structural steel bars of the edge component located in the concrete wall remain continuous, and the vertical structural steel bars of the remaining edge components are cut off; internal threaded sleeves are embedded in the prefabricated wall concrete on both sides of the installation hand hole, which are used to fix the installation hand hole sealing template on site to improve the on-site construction efficiency.

[0011] The present invention discloses a prefabricated hollow composite shear wall with vertical reinforcements of post-penetrating edge members, wherein the shaped pipes used to form vertical holes at the wall position have the same cross-section from top to bottom, and can be circular, rectangular or other cross-sectional forms as required, and the dimensions of the pipes along the wall thickness and wall length directions should not be less than 70 mm to ensure the pouring quality of post-cast concrete in the vertical holes; a shaped pipe is arranged at the center of every two rows of vertical distributed reinforcements to form a vertical hole.

[0012] The vertical distribution steel bars at the wall position do not extend out of the top and bottom surfaces of the prefabricated wall. One or two additional connecting steel bars are arranged near the floor elevation of the vertical hole at each wall position, and are overlapped and connected with the four adjacent vertical distribution steel bars in the prefabricated wall. The length of the additional connecting steel bars should meet the requirements for steel bar overlap, and they are non-continuously arranged along the height direction in the vertical hole, with a total area not less than the total area of ​​the four vertical distribution steel bars overlapped and connected with them. Within the overlap range of the vertical distribution steel bars, the tie bars that tie the two layers of steel mesh of the prefabricated wall are densely encrypted, and a tie bar is arranged at the intersection of each vertical distribution steel bar and the horizontal distribution steel bar. When two additional connecting steel bars are used, transverse steel bars can be welded at the upper and lower ends of the two additional connecting steel bars to form ladder bars, which is convenient for on-site fixation of the additional connecting steel bars and increases the force transmission performance at the same time.

[0013] The shaped pipes for forming holes in edge components and the shaped pipes for forming holes in wall positions are both made of metal and can be made by folding thin-walled steel plates with patterns or protrusions on the surface. The circular cross-section pipes can be made of metal corrugated pipes.

[0014] The present invention discloses a prefabricated hollow composite shear wall with post-pierced vertical reinforcements of edge members, wherein, within the length range of the longitudinal reinforcements at the bottom of the connecting beam, the vertical structural reinforcements and vertical distribution reinforcements of the edge members in the prefabricated wall are bent inwards at the upper part of the wall to be penetrated through the inner side of the longitudinal reinforcements at the bottom of the connecting beam, thereby ensuring that the longitudinal reinforcements of the connecting beam are arranged in a straight line without the need for bending; the bending angles of the vertical structural reinforcements and vertical distribution reinforcements of the edge members should not be greater than 1:6, and the length of the bending section should not be too long, so as to facilitate the arrangement of stirrups of the edge members; tie bars are arranged one by one at the intersections of the longitudinal reinforcements at the bottom of the connecting beam with the vertical reinforcements within the anchorage range of the walls on both sides, thereby improving the anchorage performance of the longitudinal reinforcements at the bottom of the connecting beam in the walls on both sides.

[0015] The present invention discloses a prefabricated hollow composite shear wall with vertical steel bars of edge members inserted later. When the prefabricated wall is installed on site, the horizontal joint at the bottom of the prefabricated wall should be set at the floor elevation. To ensure the compactness of the post-cast concrete at the horizontal joint, the distance between the bottom surface of the prefabricated wall and the top surface of the floor slab should not be less than 50 mm. An internal threaded sleeve is embedded at the bottom of the prefabricated wall, and bolts are screwed into the internal threaded sleeve at the construction site. The bolts are used to control the height of the horizontal joint and adjust the horizontality of the prefabricated wall.

[0016] A horizontal inner groove is arranged at the bottom of the prefabricated hollow composite shear wall to ensure that the post-poured concrete is poured densely. The horizontal groove can be formed by a template. The height of the horizontal inner groove should not be less than 80 mm. The cross-sectional shape is a trapezoidal cross-section that is narrow at the top and wide at the bottom. The width of the upper bottom of the trapezoidal cross-section should not be less than 80 mm.

[0017] The edge component structure of the present invention can be used to prefabricate straight-line, L-shaped, and T-shaped edge component positions. When used for L-shaped and T-shaped edge components, the arrangement of vertical force-bearing steel bars of the edge components in the shaped pipes and vertical holes is adjusted according to the edge component range and the amount of vertical steel bar reinforcement.

[0018] When horizontal distributed steel bars need to be extended from the side of the prefabricated hollow composite shear wall to connect with the adjacent prefabricated hollow composite shear wall or cast-in-place shear wall, the extended horizontal distributed steel bar structure and the vertical joint structure shall refer to the design specifications such as "Technical Standards for Prefabricated Concrete Buildings" and "Technical Code for Prefabricated Concrete Structures".

[0019] The prefabricated hollow composite shear wall is a structural wall and can be used for the exterior or interior walls of a building. Furthermore, the prefabricated hollow composite shear wall, the insulation layer and the outer leaf wall panel can be prefabricated as a whole in a factory to form a prefabricated sandwich insulation hollow composite shear wall, thereby realizing the integration of prefabricated exterior wall insulation, decoration and structure; the prefabricated hollow composite shear wall and the outer leaf wall panel are fastened with insulation fasteners.

[0020] The prefabricated hollow composite shear wall with vertical steel bars of the edge member inserted later described in the present invention comprises the following steps: tying the shear wall steel bar skeleton, arranging the shaping pipe in the steel bar skeleton, installing the prefabricated wall side mold, the horizontal inner groove mold and the installation hand hole placeholder, positioning the shaping pipe, pouring concrete to form the internal vertical hole, curing and forming and demoulding. Furthermore, the prefabricated sandwich insulation hollow composite shear wall can be produced by the positive method or the reverse method, adding the construction process of the outer leaf wall board, the insulation layer and the insulation tie piece.

[0021] The prefabricated hollow composite shear wall with post-through vertical reinforcement of edge members described in the present invention comprises the following steps of on-site construction process: installing the prefabricated hollow composite shear wall, adjusting the verticality and horizontality of the prefabricated wall, inserting vertical force-bearing reinforcement of edge members into vertical holes of edge members and completing the reinforcement threaded joint connection in the installation hand holes, laying additional connecting reinforcement in the vertical holes of the wall body, supporting horizontal joints and installing hand hole formwork, pouring post-through concrete in the vertical holes to realize prefabricated wall connection, and maintaining and removing the formwork.

[0028] (5) The prefabricated hollow composite shear wall of the present invention has a light weight, and the vertical distribution steel bars are connected by overlapping, and the vertical force-bearing steel bars of the edge components are inserted later, which can avoid the traditional prefabricated wall sleeve grouting joint steel bar alignment and joint grouting construction, and the on-site installation efficiency is high, which helps to save construction time.

DETAILED DESCRIPTION

[0047] The embodiments of the present invention are described in detail below with reference to the accompanying drawings and examples.

[0048] like Figure 1-Figure 16 As shown, a prefabricated hollow composite shear wall with vertical steel bars penetrating the edge components at the back mainly includes an edge component area 1 and a wall area 2.

[0049] The wall area 2 is provided with a shaped pipe 21 for wall hole formation and vertical distribution steel bars 23. A vertical hole in the wall is formed in the shaped pipe 21 for wall hole formation. The vertical distribution steel bars 23 are located outside the vertical hole in the wall and do not extend out of the top or bottom surface of the prefabricated wall. One or two vertical additional connecting steel bars 24 are arranged at the floor elevation in the vertical hole in the wall. The additional connecting steel bars 24 are overlapped and connected with the four adjacent vertical distribution steel bars 23 outside the vertical hole in the wall.

[0050] The further optimization and improvement of the present invention lies in the edge component area 1. The edge component area 1 adopts a shaping pipe 11 for edge component hole formation to form a vertical hole for the edge component, and a hand hole 12 for installation is reserved at the root of the edge component area 1 at the edge component vertical hole. In the edge component area 1 in the prefabricated wall, only small-diameter vertical structural steel bars 13 are arranged to form a steel skeleton with edge component stirrups 14 and tie bars 15. The vertical structural steel bars 13 are arranged outside the range of the vertical hole of the edge component and do not participate in the force calculation; after the prefabricated wall is installed at the construction site, the vertical force-bearing steel bars 16 for the rear-penetrating edge components are inserted into the vertical hole of the edge component, and the steel bar threaded joint 161 is used in the installation hand hole 12 to realize the connection of the vertical force-bearing steel bars 16 for the rear-penetrating edge components of the upper and lower walls. In the production stage of the prefabricated wall, the side molds are not opened, which can realize the standardization and generalization of the molds, and is convenient for the protection of the finished products during transportation and hoisting.

[0051] That is, the present invention adopts large-diameter rear-penetrating edge member vertical stress-bearing steel bars 16 to replace multiple small-diameter edge member vertical stress-bearing steel bars of traditional shear walls. The rear-penetrating edge member vertical stress-bearing steel bars 16 participate in the structural stress calculation, and the reinforcement area meets the shear wall positive section compressive bearing verification requirements, or replaces multiple small-diameter edge member vertical stress-bearing steel bars of traditional shear walls according to the principle of equal-area replacement of steel bars of the same strength grade. The replacement principle is that two 22mm diameter rear-penetrating edge member vertical stress-bearing steel bars 16 replace six 12mm diameter steel bars, two 25mm diameter rear-penetrating edge member vertical stress-bearing steel bars 16 replace six 14mm diameter steel bars, and two 28mm diameter rear-penetrating edge member vertical stress-bearing steel bars 16 replace six 16mm diameter steel bars.

[0052] In order to pass the vertical stress-bearing steel bars 16 of the edge components after on-site construction, a shaped pipe 11 for forming holes in the edge components is used to form vertical holes in the edge components that pass through the height of the wall during the prefabricated wall production stage; in order to achieve the overlapping connection of the vertical distribution steel bars 23 of the upper and lower prefabricated walls, a shaped pipe 21 for forming holes in the wall body is used to form vertical holes in the wall body that pass through the height of the wall body during the prefabricated wall production stage; after the steel bars in each vertical hole are arranged, post-pour concrete in the vertical holes is poured to complete the prefabricated wall connection; the prefabricated wall is cast and formed in one time using a fixed mold production line or a flat mold assembly line.

[0053] For the straight edge member, two edge member hole forming forming pipes 11 can be used to form two vertical holes of the edge member. The edge member hole forming forming pipes 11 have the same cross section from top to bottom, and can be circular, rectangular or other cross-sectional forms as required; the edge member hole forming forming pipes 11 can be made by rolling a thin-walled steel plate with patterns or protrusions on the surface, and a metal corrugated pipe can be used for the circular cross section. The dimensions along the wall thickness and wall length should not be less than 80mm. When the calculated reinforcement area of ​​the vertical steel bars of the straight edge member is greater than the set value, three edge member hole forming forming pipes 11 are used to form three vertical holes in the edge member area 1, and three vertical force-bearing steel bars 16 of the edge member are inserted to control their diameter.

[0054] When the prefabricated wall includes L-shaped and T-shaped prefabricated edge components, the range, stirrups and tension reinforcement of the L-shaped and T-shaped edge components are the same as those of the cast-in-place shear wall. A plurality of edge component hole-forming shaped pipes 11 are used to form a plurality of edge component vertical holes within the edge component range. A rear-penetrating edge component vertical force-bearing steel bar 16 is inserted into each edge component vertical hole. The range of the installation hand hole 12 is adjusted according to the edge component range, the operating requirements of the steel bar threaded joint 161 and the floor position.

[0055] The present invention arranges a post-penetrating edge member vertical stress-bearing steel bar 16 in each edge member hole-forming shaped pipe 11 along the center line of the wall thickness. On the basis of satisfying the construction of the steel bar threaded joint 161 in the installation hand hole 12 and the pouring of post-cast concrete in the vertical hole, the post-penetrating edge member vertical stress-bearing steel bar 16 is arranged at one side in the edge member hole-forming shaped pipe 11.

[0056] The installation hand hole 12 can be formed by using a fixed placeholder block, and the size should meet the operating space requirements when installing the steel bar threaded joint 161; the thickness of the concrete wall around the installation hand hole 12 should not be less than 40mm to prevent the concrete wall from cracking during the pouring of concrete in the vertical hole on site; within the range of the installation hand hole 12, the vertical structural steel bars 13 located in the concrete wall remain continuous, and the remaining vertical structural steel bars 13 are cut off; internal threaded sleeves 121 are embedded in the precast wall concrete on both sides of the installation hand hole 12, which are used to fix the installation hand hole sealing template on site.

[0057] When the prefabricated wall is installed on site, the horizontal joint 51 at the bottom of the prefabricated wall is set at the floor elevation. In order to ensure the compactness of the post-cast concrete at the horizontal joint 51 at the bottom of the prefabricated wall, the distance between the bottom surface of the prefabricated wall and the top surface of the floor slab is not less than 50mm; at least two internal threaded sleeves 26 are embedded in the bottom of the prefabricated wall, and bolts are screwed into the internal threaded sleeves 26 at the construction site. The bolts are used to control the height of the horizontal joint 51 at the bottom of the prefabricated wall and adjust the horizontality of the prefabricated wall; when the spacing of the shaped pipes 21 used for hole forming in the wall body is greater than the set value, in order to ensure the compactness of the post-cast concrete at the horizontal joint 51 at the bottom of the prefabricated wall at this position, a horizontal inner groove 22 is set at the bottom of the wall body, and the horizontal inner groove 22 is formed by template molding or placeholder formation; the height of the horizontal inner groove 22 is not less than 80mm, and the cross-sectional shape is a trapezoidal cross-section with narrow upper and wide lower parts, and the upper bottom width of the trapezoidal cross-section is not less than 80mm.

[0058] Within the length of the longitudinal reinforcement 31 at the bottom of the coupling beam, the vertical structural reinforcement 13 and the vertical distribution reinforcement 23 in the prefabricated wall are bent inward at the upper part of the wall to pass through the inner side of the longitudinal reinforcement 31 at the bottom of the coupling beam, ensuring that the longitudinal reinforcement 31 at the bottom of the coupling beam is arranged in a straight line without bending. The bending angle of the vertical structural reinforcement 13 and the vertical distribution reinforcement 23 of the edge components in the prefabricated wall should not be greater than 1:6. They are arranged in the prefabricated wall outside the shaped pipe 11 for hole forming in the edge components and the shaped pipe 21 for hole forming in the wall body. The prefabricated wall reinforcement cage is relatively independent of the shaped pipe to facilitate the installation of the shaped pipe.

[0059] The present invention can also prefabricate the prefabricated hollow composite shear wall 61, the insulation layer 62 and the outer leaf wall panel 63 as a whole in the factory to form a prefabricated sandwich insulation hollow composite shear wall, thereby realizing the integration of prefabricated exterior wall insulation, decoration and structure; the prefabricated hollow composite shear wall and the outer leaf wall panel are fastened with insulation anchors; the prefabricated sandwich insulation hollow composite shear wall can be produced by the forward or reverse method, thereby increasing the construction steps of the outer leaf wall panel, the insulation layer and the insulation anchors.

[0060] For example Figures 1 to 8 As shown, it is a preferred embodiment 1 of the present invention, including an edge member area 1, a wall area 2, a connecting beam area 3 and a door opening 4. It should be noted that the edge member area 1 and the wall area 2 can be used independently for a prefabricated hollow composite shear wall with vertical reinforcements of the edge member after passing through the present invention. The specific embodiment includes the connecting beam area 3 and the door opening 4 to more comprehensively illustrate the scheme of the present invention, but it does not mean that the prefabricated hollow composite shear wall with vertical reinforcements of the edge member after passing through the present invention must be used for the prefabricated shear wall containing the connecting beam area 3 and the door opening 4.

[0061] Taking into account the advantages and disadvantages of the existing prefabricated shear wall technology, the present invention adopts a shaped pipe to form an internal vertical hole. In the edge component part, only vertical structural steel bars 13 and stirrups 14 are arranged in the edge component of the prefabricated wall, and large-diameter back-through edge component vertical force-bearing steel bars 16 are used to replace multiple small-diameter edge component vertical steel bars of the traditional shear wall, which are penetrated in the vertical hole of the edge component at the construction site, and a hand hole 12 is set at the root of the prefabricated wall to realize the threaded joint 161 connection of the vertical force-bearing steel bars 16 in the vertical hole; the vertical distribution steel bars 23 of the wall body are connected by additional connection steel bar lap joints 24. The prefabricated wall can be formed in one step without the use of special hole-forming equipment. It can be produced on existing production lines such as fixed mold production lines and flat mold assembly lines that are widely used in domestic prefabricated component factories. The production process is relatively simple. The vertical structural steel bars 13 of the edge components and the vertical distribution steel bars 23 of the wall body do not extend out of the prefabricated wall. The side mold opening can be avoided in the prefabricated wall production stage, and the mold standardization and generalization can be achieved, thereby improving production efficiency, controlling the cost of prefabricated components, and facilitating the protection of finished products during transportation and hoisting.

[0062] The I-shaped edge component area 1 of the preferred embodiment 1 of the present invention uses two identical edge component hole forming shaped pipes 11 to form two edge component vertical holes. Only small-diameter vertical structural steel bars 13 are set in the edge component area of ​​the prefabricated wall to form a steel skeleton with edge component stirrups 14 and tie bars 15. The structure of the edge component stirrups 14 and tie bars 15 is consistent with that of ordinary cast-in-place shear walls; the vertical structural steel bars 13 are arranged outside the vertical hole range of the edge component, do not extend out of the prefabricated wall, and do not participate in the force calculation. Large-diameter edge component vertical stress-bearing steel bars 16 are used to replace multiple small-diameter edge component vertical stress-bearing steel bars of traditional shear walls. After the prefabricated wall is installed at the construction site, large-diameter back-through edge component vertical stress-bearing steel bars 16 are inserted into the vertical hole of the edge component, and a hand hole 12 is reserved at the root of the prefabricated wall edge component. A steel bar threaded joint 161 is used in the hand hole 12 to achieve the connection of the back-through edge component vertical stress-bearing steel bars 16 of the upper and lower walls.

[0063] The shaped pipe 11 for forming holes in edge components has the same cross-section from top to bottom, and can be circular, rectangular or other cross-sectional forms as needed. A vertical force-bearing steel bar 16 that passes through the edge component is arranged in each shaped pipe 11 for forming holes in edge components. The dimension of the pipe along the wall thickness and wall length direction should not be less than 80 mm to ensure the pouring quality of the post-poured concrete in the vertical hole.

[0064] The vertical stress-bearing steel bars 16 of the post-penetrating edge member are arranged along the center line of the wall thickness. On the basis of meeting the requirements of installing the steel bar threaded joint 161 in the hand hole 12 and pouring the post-cast concrete in the vertical hole, the vertical stress-bearing steel bars 16 of the post-penetrating edge member are arranged on one side in the shaped pipe 11 to reduce the size of the vertical hole of the edge member, which is convenient for arranging the steel bars and controlling the cost of the shaped pipe 11 for forming the hole of the edge member.

[0065] The vertical force-bearing steel bars 16 of the rear-penetrating edge members participate in the structural force calculation. The reinforcement area should meet the requirements for the shear wall positive section compressive bearing verification. It can also replace multiple small-diameter edge member vertical steel bars of the traditional shear wall according to the principle of equal-area replacement of steel bars of the same strength grade. The replacement principle is 2 22mm diameter steel bars instead of 6 12mm diameter steel bars, 2 25mm diameter steel bars instead of 6 14mm diameter steel bars, and 2 28mm diameter steel bars instead of 6 16mm diameter steel bars.

[0066] like Figure 2 As shown, the hand hole 12 installed at the root of the prefabricated wall edge component is formed by a fixed placeholder block, and the size should meet the construction space requirements for installing the steel bar threaded joint 161; after reserving the hand hole 12 for installation, the concrete wall thickness around the hand hole should not be less than 40mm to prevent the concrete wall from cracking during the post-pouring concrete in the vertical hole on site; within the range of the hand hole, the vertical structural steel bars 13 located in the concrete wall remain continuous, and the remaining vertical structural steel bars 13 are cut off; internal threaded sleeves 121 are embedded in the prefabricated wall concrete on both sides of the installation hand hole, which are used to fix the sealing template for installing the hand hole 12 on site to improve the on-site construction efficiency.

[0067] The vertical holes at the wall position are made by using a shaped pipe 21 for making holes in the wall. The shaped pipe 21 for making holes in the wall can adopt the same cross-sectional shape and size from top to bottom. In the preferred embodiment 1, the cross-section of the shaped pipe 21 for making holes in the wall is circular, and a rectangular or other cross-sectional shape can also be adopted. The dimensions along the thickness and length directions of the prefabricated wall should not be less than 70 mm; a shaped pipe 21 for making holes in the wall is arranged at the center position of every two rows of vertical distribution steel bars 23 to form a vertical hole.

[0068] The vertical distribution steel bars 23 do not extend out of the top and bottom surfaces of the prefabricated wall. Fig.10 As shown, an additional connecting steel bar 24 is arranged near the floor elevation of the vertical hole of the wall body forming pipe 21, and is overlapped and connected with four adjacent vertical distribution steel bars 23 in the prefabricated wall; within the overlap range of the vertical distribution steel bars, the tie bars 25 that tie the two layers of steel mesh of the prefabricated wall are densely packed, and a tie bar 25 is arranged at the intersection of each vertical distribution steel bar 23 and the horizontal distribution steel bar. In addition, as Fig.11 As shown, two additional connecting steel bars 24 are arranged near the floor elevation of the vertical hole of the wall body forming shaped pipe 21, and overlapped and connected with the four adjacent vertical distribution steel bars 23 in the prefabricated wall; transverse steel bars 241 can be welded at the upper and lower ends of the two additional connecting steel bars 24 to form ladder bars, which is convenient for on-site fixing of the additional connecting steel bars 24 and improves the force transmission performance. Regardless of whether one or two additional connecting steel bars 24 are used, the total area of ​​the additional connecting steel bars 24 in the vertical hole of a single wall body forming shaped pipe 21 is not less than the total area of ​​the four vertical distribution steel bars 23 overlapped and connected with it.

[0069] The shaped pipes 11 for forming holes in edge components and the shaped pipes 21 for forming holes in wall bodies are both made of metal and can be made by folding thin-walled steel plates with patterns or protrusions on the surface. The circular cross-section pipes can be made of metal bellows.

[0070] like Figure 5 As shown, within the length range of the longitudinal reinforcement 31 at the bottom of the coupling beam, the vertical structural reinforcement 13 and the vertical distribution reinforcement 23 of the edge components in the prefabricated wall are bent at the upper part of the wall to pass through the inner side of the longitudinal reinforcement 31 at the bottom of the coupling beam, ensuring that the longitudinal reinforcement 31 at the bottom of the coupling beam is arranged in a straight line without bending. The bending angle of the vertical structural reinforcement 13 and the vertical distribution reinforcement 23 should not be greater than 1:6, and the length of the bending section should be controlled to facilitate the arrangement of the stirrups 14 of the edge components. The longitudinal reinforcement 31 at the bottom of the coupling beam is within the anchorage range of the walls on both sides, and tie bars 32 are arranged one by one at the intersection with the vertical reinforcement to improve the anchorage performance of the longitudinal reinforcement 31 at the bottom of the coupling beam in the walls on both sides.

[0071] like Figures 9 to 11 As shown, when the prefabricated wall is installed on site, the horizontal joint 51 at the bottom of the prefabricated wall should be set at the floor elevation. To ensure the compactness of the post-cast concrete at the horizontal joint 51 at the bottom of the prefabricated wall, the distance between the bottom surface of the prefabricated wall and the top surface of the floor slab should not be less than 50 mm. At least two internal threaded sleeves 26 are embedded at the bottom of the prefabricated wall. Bolts are screwed into the internal threaded sleeves 26 at the construction site to control the height of the horizontal joint 51 at the bottom of the prefabricated wall and adjust the horizontality of the prefabricated wall.

[0072] In particular, the spacing of the shaped pipes 21 for forming holes in the wall is relatively large. In order to ensure the compactness of the concrete poured after the horizontal joints at the above positions, a horizontal inner groove 22 is set at the bottom of the wall and the wall under the window. The horizontal inner groove 22 can be formed by template molding or occupying. The height of the horizontal inner groove 22 should not be less than 80mm, and the cross-sectional shape is a trapezoidal cross-section with narrow upper and wide lower parts. The upper bottom width of the trapezoidal cross-section should not be less than 80mm.

[0073] When horizontal distributed steel bars need to be extended from the side of the prefabricated hollow composite shear wall to connect with the adjacent prefabricated hollow composite shear wall or cast-in-place shear wall, the extended horizontal distributed steel bar structure and vertical joint structure shall refer to the design specifications such as "Technical Standards for Prefabricated Concrete Buildings" and "Technical Code for Prefabricated Concrete Structures".

[0074] The prefabrication production process of the prefabricated hollow composite shear wall of the preferred embodiment includes the following steps: tying the shear wall steel frame, arranging the shaping pipe in the steel frame, installing the prefabricated wall side mold, the horizontal inner groove mold and the installation hand hole placeholder, positioning the shaping pipe, pouring concrete to form the internal vertical hole, and curing and molding. Its on-site construction process includes the following steps: installing the prefabricated hollow composite shear wall, adjusting the verticality and horizontality of the prefabricated wall, inserting the vertical force-bearing steel bars 16 of the edge member into the shaping pipe 11 for forming the hole of the edge member and completing the construction of the steel bar threaded joint 161 in the installation hand hole 12, arranging the additional connecting steel bars 24 at the floor elevation of the shaping pipe 21 for forming the hole of the wall body, fixing the sealing template of the installation hand hole 12 with the help of the embedded inner thread sleeve 121, supporting the horizontal joint template, pouring the post-cast concrete in the vertical hole to realize the connection of the prefabricated wall, and curing and demolding.

[0075] In particular, when the calculated reinforcement area of ​​the vertical reinforcement of the edge member is large, Figure 8 The configuration of two vertical force-bearing steel bars 16 for the rear edge members will result in a larger steel bar diameter, which is not conducive to the construction of the steel bar threaded joint 161 and the pouring of post-cast concrete in the vertical hole. Fig.12 Three edge member hole forming shaped pipes 11 are used to form three vertical holes in the edge member, and then three edge member vertical force-bearing steel bars 16 are inserted to control the diameter thereof. The reinforcement principle of the vertical force-bearing steel bars 16 is the same as before.

[0076] Fig.13 , Fig.14 and Fig.15 They are respectively preferred embodiments 2, 3 and 4 of the present invention for L-shaped prefabricated edge members, T-shaped prefabricated edge members and T-shaped prefabricated constrained edge members. The edge member range, stirrup and tie bar structures are the same as those of cast-in-place shear walls. A plurality of edge member hole-forming shaped pipes 11 are used to form a plurality of edge member vertical holes within the edge member range. A rear-penetrating edge member vertical stress-bearing steel bar 16 is inserted into each edge member vertical hole. The range of the installation hand hole 12 is adjusted according to the edge member range, the operating requirements of the steel bar threaded joint 161 and the floor position. The reinforcement principles and structural requirements of the rear-penetrating edge member vertical stress-bearing steel bar 16 are the same as those above.

[0077] Preferred embodiments 1 to 4 The prefabricated hollow composite shear walls are structural walls and can be used for building exterior walls or interior walls. Fig.16 As shown, the prefabricated hollow composite shear wall 61, the insulation layer 62 and the outer leaf wall panel 63 can be prefabricated as a whole in the factory to form a prefabricated sandwich insulation hollow composite shear wall, realizing the integration of prefabricated exterior wall insulation, decoration and structure. The prefabricated hollow composite shear wall and the outer leaf wall panel are tied with insulation tie pieces. At this time, the prefabricated sandwich insulation hollow composite shear wall can be produced by the forward method or the reverse method, adding the construction process of the outer leaf wall panel, the insulation layer and the insulation tie pieces.

[0078] The above are only preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes and substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
