Joint treatment method for fabricated building wall

Abstract

The invention discloses a joint treatment method for a fabricated building wall. The joint treatment method for the fabricated building wall comprises the following steps that (1) fabricated buildingwall components are machined; (2) lower fabricated building wall components are installed and constructed at a construction site; (3) upper fabricated building wall components are hoisted to the lowerfabricated building wall components; (4) pre-embedded protruding U-shaped steel bars of built-in fittings of the upper fabricated building wall components are horizontally connected with pre-embeddedU-shaped steel bars at the corresponding parts of adjacent upper fabricated building wall components; and (5) floors are connected by a cast-in-situ mode. A wall formed by the joint treatment methodis integral, and the joint treatment method for the fabricated building wall has the characteristics of simple and convenient fabrication, short construction period and high connection strength.

Description

technical field [0001] The invention relates to the technical field of architectural structure design, in particular to a node processing method of a prefabricated building wall. Background technique [0002] Domestic reinforced concrete building structures (especially high-rise frame-shearing residential projects) are mostly constructed with cast-in-place concrete. The on-site construction period is long, and the environmental pollution caused by dust and noise is serious. The negative impact of construction on traffic and the environment is great. The energy consumption of processing and construction is high, the material loss of construction measures is large, and there is a lot of construction waste; the construction management is extensive, there are many loopholes in cutting corners, and the construction is highly dependent on the weather; the efficiency of construction enterprises is low, and technological innovation is slow.

[0002] Domestic reinforced concrete building structures (especially high-rise frame-shearing residential projects) are mostly constructed with cast-in-place concrete construction. The on-site construction period is long, and the environmental pollution caused by dust and noise is serious. The negative impact of construction on traffic and the environment is great. High energy consumption in processing and construction, large loss of materials in construction measures, and a lot of construction waste; extensive construction management, many loopholes in cutting corners, construction is highly dependent on the weather; construction enterprises are low in efficiency, and technological innovation is slow

[0003] The upgrading model of the construction industry, which is built with reinforced concrete components, has been supported by national policies and is one of the trends in the upgrading and development of the construction industry. It has been praised by people for its short construction period and high degree of factoryization. Prefabricated buildings have always had the problem that the wall and the overall structure cannot form a unified system, and the key to the problem lies in the node connection of the prefabricated wall. Most of the existing prefabricated wall node structures have weak structural integrity and poor earthquake resistance. Poor, it is very easy to cause deformation and cracks in the prefabricated wall, and its connection form cannot meet the higher requirements of the prefabricated building.
