Description

Technical Field

[0002] With the development of prefabricated buildings, steel structures or reinforced concrete shear walls are generally used. The degree of automation of steel structures is relatively high. The structural systems of steel residential buildings are mostly based on the logic of special-shaped column frames or short-leg shear walls. The starting point of the conceptual design is mainly to solve the problem of indoor convex beams and visible columns. However, steel structures still have the following technical problems, such as 1) Joint cracking problems. The deformation difference between the main structure and the filling enclosure system causes cracking, resulting in water seepage and cold joints, which are particularly serious for the outer enclosure. 2) Sound insulation, fire prevention, and corrosion prevention problems of steel structures. The sound insulation effect of steel structures is poor; fire prevention and corrosion prevention problems are prominent, and the processing cost is high. 3) The problem of intelligent construction. The structural system has not yet truly realized intelligent construction.

[0003] The reinforced concrete shear wall structure currently used is still a traditional reinforced concrete structure. Due to the structural characteristics of its steel frame, it is difficult to achieve vertical stability. Generally, a flat casting method is adopted during prefabrication, which occupies a large area. In addition, rebars are generally provided at the edges of the wall panels, resulting in relatively complex component molds. The molds cannot be standardized. Most of the steel bars of its steel frame are manually tied and cannot be automated, resulting in low production efficiency. In addition, the structural form of the rebars is inconvenient to transport, hoist and install, resulting in low construction efficiency. Summary of the invention

[0007] As an optimization, the first steel mesh and the second steel mesh both include cross-arranged horizontal steel bars and vertical steel bars, and the corresponding parts of the vertical steel bars of the first steel mesh and the second steel mesh are connected by stirrups to form a plurality of columnar steel skeletons.

[0008] As an optimization, there are two columnar steel bar skeletons, which are close to both ends of the wall panel along the width direction.

DETAILED DESCRIPTION

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Specific implementation: Example 1, see Figure 1 ,

[0023] A shear wall structure includes a concrete wall panel 1 and a steel frame wrapped in the wall panel 1, 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 1 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 parts of the vertical steel bars of the first steel mesh 2 and the second steel mesh 3 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 1 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 1 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 1 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 first steel mesh 2 and the second steel mesh 3, 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 steel mesh can be standardized and automatically processed. In addition, the truss 4 is convenient for pre-embedding and pre-reservation as a skeleton support structure, 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.

[0024] The wall panel 1 is also provided with a plurality of vertical connection holes 5 extending along the height direction of the wall panel 1, and the plurality of vertical connection holes 5 are distributed along the width direction of the wall panel 1, 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 is inserted into the vertical connection hole 5, and the connection truss may be a same 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.

[0025] A horizontal connection structure is provided on at least one side of the vertical surface of the wall panel 1 for horizontal connection with the building structure. Specifically, the horizontal connection structure includes a connection groove 8 provided on at least one side of the vertical surface of the wall panel 1, the connection groove 8 is arranged along the height direction of the wall panel 1 or arranged 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. Correspondingly, the same connection groove 8 is provided at the adjacent building structure where the shear wall is pre-installed, and a flexible lasso 10 or anchor ring 9 matching with the anchor ring 9 or the flexible lasso 10 is pre-buried in the connection groove 8, so that the anchor ring 9 matches with the flexible lasso 10. In this way, during installation, since the flexible lasso 10 itself can be deformed, when the shear wall is placed from top to bottom, 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 the center holes are opposite, which is convenient for inserting the dowel and pouring concrete in the center hole to achieve horizontal connection, avoiding the problem of mutual interference between anchor rings and inconvenient installation 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 facade adjacent to the side facade with the connection groove 8 on the wall panel 1. The operation grooves penetrate the two adjacent side facades and are connected to the connection groove 8, and correspond to the positions of the threaded sleeve or the lasso. In this way, it is convenient to operate the anchor ring 9 and the flexible lasso 10 as a hand hole when encountering special circumstances, and it is also convenient to observe the matching situation of the anchor ring 9 and the flexible lasso 10. At the same time, after pouring concrete, the post-cast part forms a complex mosaic structure to improve the overall strength of the horizontal connection.

[0026] Example 2, see Figure 2, which is different from the first embodiment, a corrugated steel plate 11 is provided between the first steel mesh 2 and the second steel mesh 3, and the crest and trough of the corrugated steel plate 11 are connected to the first steel mesh 2 and the second steel mesh 3 respectively. Specifically, the corrugated steel plate 11 is provided between adjacent columnar steel skeletons 7, and its two ends are respectively welded to the stirrups 6 of the columnar steel skeletons 7, and its crest and trough extend along the height direction of the wall panel 1, and the two ends of the corrugated steel plate 11 are connected to the columnar steel skeletons 7. The corrugated steel plate 11 includes crest plates and trough plates that are alternately and staggered, and the crest plates and trough plates are connected by inclined web plates, and a plurality of through holes that are spaced along the height direction of the wall panel 1 are provided on the inclined web plates, which facilitates the flowability of concrete during pouring, improves the uniformity of pouring, and improves the integrity of the wall panel 1. The corrugated steel plate 11 can play the role of tying steel bars, and has a certain restraining ability on concrete, which can appropriately improve the ductility of the wall, and the corrugated steel plate and the steel mesh can be standardized and automatically processed and formed. The vertical connection holes 5 are distributed between adjacent inclined webs and in the columnar steel bar skeleton 7. The corrugated steel plate 11 is used as a skeleton for easy pre-embedding and pre-reservation, and can realize the vertical forming process of the wall panel (the traditional steel skeleton is relatively soft and cannot be positioned for pre-embedding and pre-reservation, so it cannot be produced vertically), reducing production costs, improving the degree of automation, and realizing smart construction.

[0028] The steel bar structure is not exposed, and the starting point of retaining the steel bar skeleton assembled from standardized products is laid for automated assembly. The production mold is easy to standardize and simplify. The truss forms longitudinal ribs inside the wall panel, which will hinder the development of through cracks, so that the hysteresis performance and energy consumption capacity of the wall panel are improved. The truss is a vertical stability component, which is convenient for vertical molding production, reduces the floor space, improves the utilization efficiency of the plant, and reduces fixed costs. At the same time, independent vertical connection holes and horizontal connection structures are set on the shear wall to achieve vertical and horizontal connections, which is convenient for installation and improves construction efficiency.
