DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] For specific implementation: see Figure 1-3 ,

[0024] A shear wall transverse connection structure comprises at least one shear wall 1. A horizontal connection structure is provided on at least one side elevation of the shear wall 1 for horizontal connection with a building structure, wherein the building structure comprises a prefabricated or cast-in-place wall structure or a column structure or a beam structure or a floor structure, and is connected to the shear wall in a straight line, an L shape or a T shape. Specifically, the horizontal connection structure includes a connection groove 8 opened on at least one side of the vertical surface of the shear wall, and the connection groove 8 is arranged along the height direction of the wall panel or at intervals, and a plurality of anchor rings 9 or threaded sleeves or flexible lassos 10 for installing the anchor rings 9 are pre-buried in the connection groove 8, and the anchor rings 9 are installed on the threaded sleeves; the flexible lassos 10 matched with the anchor rings 9 or the anchor rings 9 matched with the flexible lassos 10 are correspondingly arranged in the building structure; there is a spacing between the shear wall 1 and the building structure, and the matching anchor rings 9 and flexible lassos 10 are staggered so that the center hole of the anchor ring 9 is opposite to the center hole of the flexible lasso 10, and a full-length dowel bar 13 is vertically inserted in the center hole, and concrete is poured in the spacing between the shear wall 1 and the building structure and in the area formed by the connection groove 8.

[0025] In this way, during installation, since the flexible lasso 10 itself can be deformed, when placing the shear wall 1, the flexible lasso 10 can well pass over the rigid anchor ring 9. Finally, the anchor ring 9 and the flexible lasso 10 are staggered and arranged with the center holes facing each other, which is convenient for inserting the dowel 13 and pouring concrete, realizing horizontal connection, avoiding the problem that the anchor rings 9 interfere with each other and are inconvenient to install in the traditional connection method that all uses anchor rings and dowels. In addition, in order to further improve the convenience of installation, a plurality of operation grooves are arranged at intervals on the side facades adjacent to the side facades with the connection grooves 8 on the wallboard. The operation grooves penetrate the two adjacent side facades and communicate with the connection grooves 8, and correspond to the positions of the anchor rings, threaded sleeves or flexible lassos. In this way, it is convenient to operate the anchor rings 9 and the flexible lasso 10 when encountering special circumstances, and it is also convenient to observe the matching of the anchor rings 9 and the flexible lasso 10. At the same time, after pouring concrete, the post-cast part forms a complex mosaic structure, which improves the overall strength of the horizontal connection.

[0026] The shear wall 1 includes a concrete wall panel and a steel frame wrapped in the wall panel, wherein the steel frame includes a first steel mesh 2 and a second steel mesh 3 respectively arranged on opposite sides of the wall panel along the thickness direction thereof, specifically, the first steel mesh 2 and the second steel mesh 3 both include horizontal steel bars and vertical steel bars arranged crosswise, and the corresponding vertical steel bars of the first steel mesh and the second steel mesh are connected by stirrups 6 to form a plurality of columnar steel frame 7, wherein the stirrups 6 are spiral stirrups. In this embodiment, there are two columnar steel frame 7, which are close to both ends of the wall panel along the width direction to form a square column structure, thereby improving the overall strength and stability of the shear wall. A plurality of trusses 4 extending along the height direction of the wall panel are arranged between the first steel mesh 2 and the second steel mesh 3, and the plurality of trusses 4 are distributed along the width direction of the wall panel and are respectively connected to the first steel mesh 2 and the second steel mesh 3. Specifically, the truss 4 can be a plane truss or a triangular truss, or other forms of truss structures. A plurality of the trusses 4 are spaced and distributed between adjacent columnar steel skeletons 7. The truss 4 can play the role of tying the steel mesh, and at the same time has a certain restraining ability on the concrete, which can appropriately improve the ductility of the wall, and the truss and the steel mesh can be standardized and automatically processed and formed. The truss 4 is convenient for pre-embedding and pre-reservation as a skeleton, and can realize the vertical forming process of the wall panel (the traditional steel skeleton is relatively soft, and the pre-embedding and pre-reservation cannot be positioned, so it cannot be produced vertically), reducing production costs, improving the degree of automation, and realizing smart construction.

[0027] The wall panel is also provided with a plurality of vertical connection holes 5 extending in the height direction of the wall panel, and the plurality of vertical connection holes 5 are distributed in the width direction of the wall panel for vertical connection with the building structure; specifically, at least one vertical connection hole 5 is provided between adjacent trusses 4 and in the columnar steel bar skeleton 7 to ensure the overall strength and stability. During installation, a connection truss 11 is inserted into the vertical connection hole 5, and the connection truss 11 may be a similar plane truss or a triangular truss to act as a connection bar, and concrete is poured in the vertical connection hole 5 to achieve vertical connection of the shear wall.

[0028] The utility model,

[0029] By adopting a connection method in which a rigid anchor ring is matched with a flexible lasso, during the installation of the shear wall, the flexible lasso can avoid the rigid anchor ring by deformation, and after the shear wall is installed in place, the rigid anchor ring can support the flexible lasso and ensure that the center holes are relative to each other to facilitate the insertion of the reinforcing bars. At the same time, through the cooperation of the flexible lasso and the rigid anchor ring, it can adapt to a variety of shear wall layouts, and the installation is more flexible and convenient. A connection groove is opened on the side facade of the shear wall to increase the cross-sectional area of ​​the grouting part and improve the connection strength.
