AI Technical Summary
In prefabricated shear wall buildings, the connecting joints at the floor and the ground become a weak point for water leakage, especially in rooms with large water use, such as bathrooms and kitchens, and the prior art is difficult to effectively prevent water leakage.
The horizontal connection position between the upper prefabricated shear wall and the lower prefabricated shear wall is raised to above the floor elevation of the room, and the connection method of embedded steel plates and water-stop steel plates is adopted to ensure the rigid waterproof effect of horizontal and vertical connections.
By improving the connection position and using water stop steel plates, the rigid waterproof performance around the floor of the water-using room is significantly enhanced to avoid water leakage.

Abstract
Description
Technical field:
[0001] The utility model relates to the field of construction engineering, in particular to the design and construction of an assembled shear wall structure, which is a structural construction method for strengthening rigid waterproofing around the floor of a water-using room in an assembled shear wall building. Background technology:
[0002] In the prefabricated shear wall structure of a construction project, the upper prefabricated shear wall is connected to the lower prefabricated shear wall at the floor level, forming a structural construction joint, which becomes a weak point for water leakage; the connection between the prefabricated shear wall and the cast-in-place edge component forms a structural construction joint, which also becomes a weak point for water leakage. Utility model content:
[0003] The utility model provides a structural structure to strengthen the rigid waterproofing around water-using rooms in prefabricated shear wall buildings. Water-using rooms refer to rooms such as bathrooms and kitchens that use a lot of water and require rigid waterproofing.
[0004] The solutions provided by this utility model include:
[0005] The horizontal connection position of the upper and lower precast shear walls is raised from the floor level to a certain height above the room floor level. The specific height can be determined based on specific conditions such as waterproofing. This allows the horizontal connection joints of the precast shear walls to avoid the floor surface where water is concentrated.
[0006] The connection between the prefabricated shear wall and the floor slab at the floor level adopts the connection method of reserved steel plate embedded parts. The waterstop steel plate is welded to the embedded steel plate, and the steel bars of the cast-in-place slab or the cast-in-place layer of the composite slab are welded to the embedded steel plate. After the concrete is poured into the cast-in-place slab or the cast-in-place layer of the composite slab, the waterstop steel plate plays a rigid waterproofing role at the horizontal connection joint between the floor slab and the prefabricated shear wall.
[0007] The concrete of the cast-in-place edge component is poured to the position of the horizontal connection joint of the precast shear wall above the floor elevation of the room. The connection between the cast-in-place edge component and the floor slab adopts the connection method of reserved steel plate embedded parts. The waterstop steel plate is welded to the embedded steel plate, and the steel bars of the cast-in-place slab or the cast-in-place layer of the composite slab are welded to the embedded steel plate. After the concrete of the cast-in-place slab or the cast-in-place layer of the composite slab is poured, the waterstop steel plate plays a rigid waterproof role at the horizontal joint between the cast-in-place edge component and the floor slab.
[0008] The vertical connection between the precast shear wall and the cast-in-place edge component adopts the connection method of reserved waterstop steel plate, that is, the precast shear wall reserves waterstop steel plate at the vertical joint. After the cast-in-place edge concrete component is poured, the waterstop steel plate plays a rigid waterproof role at the vertical joint between the cast-in-place edge component and the precast shear wall. Description of the drawings:

Cast-in-place layer of composite slab; 6. Embedded steel parts; 7. Waterstop steel plate; 8. Steel support; 9. Upper layer of composite slab steel bar; 10. Reinforced steel bar of composite slab; 11.

Horizontal construction joint. Specific implementation method:
[0012] The horizontal connection between the upper precast shear wall and the lower shear wall is located at a certain height above the floor level, and the precast shear wall is designed, produced, and constructed accordingly. Steel plate embedded parts are reserved for the precast shear wall at the floor level, and waterstop steel plates are reserved at the vertical intersection with the cast-in-place edge components. After the precast shear wall is hoisted and secured in place, the cast-in-place edge components are cast in-situ. The cast-in-situ edge components are constructed to the horizontal joint position of the precast shear wall above the room floor level, and steel plate embedded parts are reserved at the floor level. The waterstop steel plates are welded to the embedded steel plates. Construction of the composite slab and cast-in-situ slab is carried out. For the precast base plate of the composite slab, supports need to be welded to the embedded steel plates. The upper and lower layers of steel bars of the cast-in-situ slab, or the steel bars of the cast-in-situ layer of the composite slab, are welded to the embedded steel plates. After the steel bars of the composite slab or cast-in-situ slab are tied, the concrete of the cast-in-situ slab or the cast-in-situ layer of the composite slab is poured. During the service phase, the waterstop steel plates provide rigid waterproofing at the joints.
