detailed description

In order to enable those skilled in the art to better understand the technical solution of the utility model, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1-5, a prefabricated high-performance concrete constrained shear wall includes walls 1 arranged in parallel, and a plurality of ribs 2 are vertically arranged between two walls 1, and the walls A reinforcement system is buried in the body 1 and the ribs 2, and a plurality of the ribs 2 are arranged in parallel, and the ribs 2 and the wall 1 are surrounded by a plurality of cavities, and the cavities are filled with concrete layers 3. The wall 1, the rib plate 2, and the steel bar system are used as prefabricated parts in the factory after pouring and curing, and then transported to the construction site. After hoisting in place, concrete is poured in the cavity. After pouring and molding, a complete surface is formed after curing. For high-performance concrete constrained shear walls, in a more preferred solution, the cavity is a rectangle with four chamfered corners, and the connection between the rib plate and the wall panels on both sides forms a relatively round and smooth transition due to the chamfering of the holes.

In this embodiment, the reinforcing bar system includes reinforcing mesh 4 distributed in the wall body 1 and drag hook reinforcing bars 5 distributed in the ribs 2. Net 4 hook. The hook steel bar connects the steel bars in the two wall panels to form a high-strength prefabricated skeleton, cancels the truss steel bar, and saves the amount of steel bar.

In this embodiment, the reinforcement mesh 4 is formed by intersecting horizontal reinforcement bars 41 and vertical reinforcement bars 42 , and the drag hook reinforcement bars 5 are hooked to the intersection points of the horizontal reinforcement bars 41 and the vertical reinforcement bars 42 . In a more preferred solution, the vertical steel bars are arranged near both ends of the ribs.

In this embodiment, the projection of the drag hook steel bars 5 on the wall body 1 is distributed in a quincunx shape. Adopting this structure not only has superior mechanical performance, but also saves cost.

In this embodiment, the wall body 1 and the rib plate 2 are integrally cast and formed. Different from the existing double-sided laminated shear wall, which is to pour one wall panel and turn it over to pour the other side, the two shear walls are connected by truss reinforcement, which adopts integral casting and cancels the truss reinforcement, which makes the process more convenient and Save steel consumption.

In this embodiment, the walls 1 and ribs 2 are poured with high-grade concrete, and the concrete layer 3 can be poured on-site with lower-grade concrete. The prefabricated part and the poured part on the construction site are jointly stressed after forming a whole. Under the action of vertical load, the high-grade concrete of the prefabricated part forms a constraint on the lower-grade concrete poured inside, which can increase the compressive bearing capacity of the lower-grade concrete inside. The overall mechanical performance is superior to achieve the purpose of saving costs. In the preferred scheme, C50, C55, C60, C65, C70, C75, C80, etc. can be used for higher-grade concrete, and C20 can be used for lower-grade concrete. , C25, C30, C35, C40, C45, etc.

Finally, it needs to be explained that the above description is only a preferred embodiment of the utility model. Under the inspiration of the utility model, those skilled in the art can make a variety of similar implementations without violating the purpose and claims of the utility model. It means that such transformations all fall within the protection scope of the present utility model.
