Construction method for reinforced concrete prefabricated house

Abstract

The invention provides a construction method for a reinforced concrete prefabricated house. The method comprises the following steps of constructing a foundation; mounting prefabricated wallboards; casting in situ T-shaped, L-shaped and inline vertical heel posts; pouring micro-expansion mortar into vertical steel tie preformed holes in the upper and lower ends of the prefabricated wallboards; mounting reinforced concrete prefabricated superimposed beams; mounting reinforced concrete prefabricated stairs and flat stepping plates; mounting prefabricated superimposed floor slabs on the prefabricated superimposed beams; welding and binding corresponding reinforcements exposed from the prefabricated superimposed floor slabs, the upper ends of the prefabricated superimposed beams and the prefabricated wallboards into a whole, and inserting vertical anchor bars for fixing the upper and lower end parts of the prefabricated superimposed beams and the wallboards, and casting self-compacting concrete on the upper parts of the prefabricated superimposed floor slabs. A 100m-high building can be constructed in an 8 earthquake fortification region such as Beijing by sequential and cyclic construction to a design top layer from bottom to top. According to the method, a technical index of building energy efficiency of 75 percent can be achieved, and the development of a prefabricated house construction technology can be accelerated.

Description

technical field [0001] The invention relates to the technical field of house construction, in particular to a construction method for a reinforced concrete prefabricated house. Background technique [0002] As early as the 1950s, China began to use prefabricated buildings, but the prefabricated building technology has been developing slowly in China, and the technology lags behind the world level. In 2009, 8 departments of the State Council jointly issued a document announcing the comprehensive launch of scientific research, demonstration and promotion of prefabricated buildings in China, and the General Office of the State Council issued a notice on forwarding the green building action plan of the Development and Reform Commission and the Ministry of Housing and Urban-Rural Development [Guobanfa [2013] No. 1 ], housing and urban-rural construction and other departments should speed up the establishment of a standard system that promotes the design, construction, and part pr...

Problems solved by technology

[0003] However, the structure of the existing prefabricated houses is unreasonable, the innovation points of the component manufacturing process are relatively small, and the starting point of the innovation point of the component installation and construction process is low, resulting in a higher construction cost than the current technology in use, so it is difficult to promote
