Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, specifically to a steel beam fixing structure for a precast concrete shear wall. Background Technology

[0002] Shear wall structures are lateral force resisting systems that resist horizontal loads. Under seismic loading, shear walls not only bear vertical loads but also bear most of the seismic shear force; their seismic performance plays a decisive role in the overall seismic performance of the structure. With increasing building height or seismic intensity, traditional reinforced concrete shear walls are no longer sufficient to meet design requirements. Steel plate-concrete composite shear walls combine the properties of steel and concrete, offering advantages such as high energy dissipation capacity, thin outer steel plate, thinner wall thickness, flexible layout, lower cost, and prevention of exposed cracks. They represent a promising lateral force resisting component.

[0003] Currently, there are some problems with the connection nodes between steel plate concrete composite shear walls and steel beams, such as: large amount of on-site welding, inconvenient construction, and difficulty in guaranteeing the stress performance of the nodes.

[0004] As disclosed in Chinese Patent CN210032120U, a semi-rigid steel plate concrete composite shear wall and steel beam connection structure is constructed by prefabricating the steel plate concrete composite shear wall, steel beam, and reserved beam ends. The reserved beam ends have pre-drilled bolt holes in their sealing plates, and the vertical plates, sealing plates, and reinforcing ribs in the reserved beam ends are welded together. The steel plate concrete composite shear wall is then welded to the vertical plates in the reserved beam ends; the steel beam sealing plates are welded to the steel beams. On-site, the sealing plates in the reserved beam ends are directly connected to the steel beam sealing plates in the steel beams using high-strength bolts, achieving overall assembly.

[0005] However, in existing technologies, after the steel beams are installed, it is necessary to ensure the stability of the connection between the steel beams and the concrete shear wall, and to ensure the supporting force during use, so as to guarantee the safety during subsequent use.

[0006] Therefore, we urgently need to provide a steel beam fixing structure for precast concrete shear walls. Utility Model Content

[0007] The purpose of this utility model is to provide a steel beam fixing structure for precast concrete shear walls, so as to solve the problem mentioned in the background art that after the steel beam is installed, it is necessary to ensure the connection stability between the steel beam and the concrete shear wall, and the support force during use must be guaranteed, so as to ensure the safety during subsequent use.

[0009] The steel beam fixing structure includes a connecting unit and a limiting unit, with the limiting unit located at both ends of the connecting unit.

[0010] The connecting unit includes a beam, with connecting plates installed on the outer surface of the beam near the left and right sides, connecting bolts installed at both ends of the beam, and stress blocks installed on the outer surface of the beam near the connecting plates.

[0012] Preferably, the connecting plate is fixedly installed inside the rectangular grooves at the top and bottom of the left and right sides of the shear wall. The left and right ends of the beam are connected to the rectangular grooves in the shear wall via connecting bolts.

The fixing block is installed inside the rectangular holes at the middle of the top surface of the beam, near the left and right ends. The stress block abuts against the connecting plate, and the outer surface of the beam is engaged with the inner wall of the I-shaped through hole in the connecting plate.

[0013] Preferably, the reinforcing structure includes a positioning plate, with limiting plates installed near the left and right sides of the positioning plate. The limiting plates have circular holes with reinforcing ribs connected to their inner walls, and fixing nuts are installed at the top and bottom of the reinforcing ribs.

[0014] Preferably, the outer surfaces of the left and right ends of the positioning plate are connected to the inner walls of the rectangular through holes at the left and right ends of the beam. The reinforcing ribs are fixedly installed inside the shear wall. The limiting plates are fixedly installed on the front and back of the positioning plate near the left and right sides. The reinforcing ribs are the reinforcing steel bars used in the prior art.

[0015] Preferably, the orientation structure includes an orientation block, the orientation block has an internal orientation rib, and the orientation block has orientation plates on its left and right sides.

The outer surface of the directional plate is internally engaged with the top and bottom surfaces of the shear wall through slots. The directional reinforcement is a steel reinforcement structure used in the prior art.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The steel beam fixing structure of the precast concrete shear wall, through the setting of the steel beam fixing structure, utilizes the insertion of the beam body and the connecting plate, and the fixing connection of the beam body using connecting bolts, and utilizes the abutment support of stress blocks, and then uses the limiting reinforcement to limit the connection of the fixing blocks, thereby ensuring the support stability of the beam body installation.

[0019] 2.

Fixing blocks 106 are arranged between two sets of limiting ribs 105, close to each other on one side. Fixing bolts 107 are installed on the right side of the fixing blocks 106 near the top and bottom.

[0029] The connecting plate 102 is fixedly installed inside the rectangular grooves at the top and bottom of the left and right sides of the shear wall 1. The left and right ends of the beam 101 are connected to the rectangular grooves of the shear wall 1 through the connecting bolts 103. The outer surface of the limiting bar 105 is connected to the inner wall of the round hole at the left and right ends of the beam 101. The fixing block 106 is installed in the middle of the top surface of the beam 101 near the rectangular hole at the left and right ends.

[0030] By setting up a steel beam fixing structure, using the insertion of the beam 101 and the connecting plate 102, and using the connecting bolt 103 to fix the beam 101, and using the abutment support of the stress block 104, and then using the limiting rib 105 to fix the limiting connection of the fixing block 106, the support stability of the beam 101 installation is ensured.

[0031] When installing and connecting the shear wall 1 and the beam 101, the beam 101 is installed by inserting it into the connecting plate 102. Then, the beam 101 is fixed by the connecting bolt 103. Next, the limiting bar 105 is inserted into the shear wall 1 to limit the beam 101. The fixing block 106 is installed into the rectangular holes near both ends on the outer surface of the beam 101. Then, the fixing block 106 is connected to the connecting plate 102 by the fixing bolt 107. Finally, concrete is poured into the rectangular grooves at the top and bottom of the left and right sides of the shear wall 1 to ensure the stability of the fixed structure. Example

[0035] During the installation of the shear wall 1 and the beam 101, the positioning plate 201 is engaged with the rectangular through holes at both ends of the beam 101. Then, the reinforcing rib 203 is connected to the limiting plate 202, and the limiting plate 202 and the positioning plate 201 are installed using the fixing nut 204. When the positioning plate 201 is installed, the directional rib 302 is engaged with the directional block 301, and the directional plate 303 is engaged with the inner wall of the rectangular slots in the middle of the top and bottom surfaces of the shear wall 1. This facilitates the installation and positioning of the positioning plate 201.
