Problems solved by technology

However, the shear wall is a traditional reinforced concrete structure, and its own weight is relatively large, which increases the self-weight of the structure to a certain extent, and at the same time causes an increase in the budget cost

Embodiment Construction

[0023] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0024] The invention provides a prestressed assembled plate-column structure with steel support, which can improve the anti-seismic performance of the structure and can effectively improve the construction efficiency. Such as Figure 2-6 As shown, the entire structure is composed of prefabricated columns 1 with embedded parts 3, prefabricated slabs 2 and steel supports 5 (the steel supports 5 shown in the figure are only schematically shown), and the prefabricated slabs 2 are two-way ribbed ribbed prefabricated panels. Steel supports 5 are cross-connected to embedded parts ...

Abstract

The invention relates to a prestressed assembled board column structure with steel supports. The prestressed assembled board column structure consists of prefabricated columns (1) with built-in fittings (3), prefabricated boards (2) and steel supports (5), wherein the prefabricated boards are rib-dense prefabricated boards with ribs in dual directions; the built-in fittings and the prefabricated columns are molded integrally by pouring; the prefabricated columns are connected together with the prefabricated boards via prestress and friction force produced by prestressed ribs; and the steel supports are connected with the built-in fittings through high-strength bolts. Each built-in fitting consists of two pieces of single-angle steel (6), a node plate (7) and four bolts (9) with bent hooks; each node plate is spliced between the first sides of every two pieces of single-angle steel (6); and the bolts extend out of the second sides of the single-angle steel and are anchored in the prefabricated columns respectively. The prestressed assembled board column structure disclosed by the invention is convenient to install, is low in cost, is high in seismic resistance, and is suitable for the technical field of seismic resistance in building structures.

Description

technical field [0001] The invention relates to a prestressed assembled slab-column structure with steel support and a construction method thereof, which is suitable for the technical field of anti-seismic building structures. Background technique [0002] The prestressed prefabricated slab-column structure is a structure that uses prefabricated slabs and prefabricated columns through prestressed connections. The structure is widely used because of its convenient manufacture, simple assembly and good structural performance. Among them, how to improve the seismic performance of prestressed prefabricated slab-column structures is a very important issue. [0003] Such as figure 1 As shown, the traditional prestressed prefabricated slab-column structure is composed of prefabricated columns 1 and prefabricated slabs 2. In order to improve the seismic performance of the structure, a certain number of shear walls 4 are sometimes added to meet the seismic requirements of the struc...
