Integrated prefabrication method for connecting concrete shear wall and filler wall

Abstract

The invention relates to an integrated prefabrication method for connecting a concrete shear wall and a filler wall, and belongs to the technical field of buildings. The integrated prefabrication method comprises a prefabricated concrete shear wall, a prefabricated filler wall, a soft material and prefabricated filler wall steel wires. The integrated prefabrication method is realized through the following steps: carrying out form erecting according to design requirements; binding reinforcing steel bars and steel wires of a wall body; putting corresponding molds into the prefabricated concrete shear wall and the prefabricated filler wall if the prefabricated concrete shear wall and the prefabricated filler wall are hollow; putting the soft material between the prefabricated concrete shear wall and the prefabricated filler wall; pouring wall body concrete for demolding after maintenance. The method can ignore the influence of the filler wall on the lateral-displacement-resistant rigidity of the overall structure, the structure stress is accurate, the force transmission lines are clear, and the reliability of the structure is guaranteed; moreover, the integrated prefabrication method is simple, the production and construction mounting of prefabricated parts are facilitated, the quality and efficiency are improved, the construction cost is reduced, and the method has positive meanings for the development of prefabricated concrete construction.

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
