A connection method of integrated prefabrication of concrete shear wall and filling wall

Abstract

A connection method for integrated prefabrication of concrete shear walls and infill walls, which belongs to the technical field of construction, including prefabricated concrete shear walls, prefabricated infill walls, soft materials, and prefabricated infill wall steel wires, and is realized through the following steps: According to the design Formwork is required; wall reinforcement and steel wires are bound; if precast concrete shear walls and prefabricated infill walls are hollow, corresponding molds should be placed; soft materials between precast concrete shear walls and prefabricated infill walls should be placed; pouring The wall concrete is demoulded after curing. The present invention can ignore the impact of the filling wall on the anti-sway stiffness of the overall structure, the structural force is clear, the force transmission route is clear, and the reliability of the structure is guaranteed; at the same time, the integrated prefabrication method is simple, which is convenient for the production, construction and installation of prefabricated components, and improves It improves the quality and efficiency, reduces the construction cost, and has positive significance for the development of prefabricated concrete buildings.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to an assembled concrete structure. Background technique [0002] There are three main types of filling walls for prefabricated concrete shear wall structures: [0003] The first category is post-masonry methods, see Code for Design of Masonry Structures (GB50003-2011). Belonging to the traditional construction method, the consumption of materials and manpower is high, the cost is high, the quality is poor, and the work efficiency is low. [0004] The second category is site-installed prefabricated wall panel infill walls. See "Steel Grid Cement Polystyrene Sandwich Wall" (Atlas No.: 05J3-5) jointly compiled by Hebei, Tianjin, Shanxi, Inner Mongolia, and Henan, and published by China Building Industry Press; Jiangsu Provincial Architectural Standard Design Atlas " Lightweight Wall Panel Structure Atlas" (Atlas No.: Su JT15-2005); Guangdong Provincial Building Sta...

Problems solved by technology

The common problems of the connection methods shown in the above diagrams are: the connection is only a simple pasting connection or a high-ductility and low-strength fiber material pasting connection, and no tensile steel wire or steel bar is used to connect the two as a whole, which cannot resist the building. The cracking phenomenon between the prefabricated non-load-bearing wall and the structural components due to dry shrinkage and cold shrinkage causes the connection to fail, affects the visual effect of the wall, damages the quality of the house, and brings unnecessary troubles to users

According to Article 13.2.1, Paragraph 2 of the "Code for Seismic Design of Buildings" (GB50011-2010), it is stipulated that "the rigidity of non-structural components embedded in the plane of lateral force-resistant components shall be included in the rigidity effect", which is actually It is a very difficult job in engineering design, because there is no calculation method how to take its stiffness into account
