Abstract

The invention discloses a construction method of a modular fabricated steel structure house. The construction method specifically comprises the following steps including (1) house modular design; (2)steel structure wall surface treatment; (3) foundation construction; (4) steel structure skeleton mounting; (5) structure modular construction; (6) structure module inside concrete pouring; (7) prefabricated exterior wall mounting; and (8) water, electricity and heating pipeline connection. According to the construction method provided by the invention, by spraying polymer mortar on steel structure walls and to-be-poured surfaces, the bonding force between a steel structure and concrete interfaces and the corrosion resistance of the steel structure are enhanced; foundation pouring concrete isprepared by adopting a strong retarding type polycarboxylic acid water reducer, and concrete internal stress cracking is reduced; and a foundation concrete vibrating bar is wrapped with a polytetrafluoroethylene coating, and the foundation concrete compactness, mechanical property and durability are improved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a construction method for a modular assembled steel structure house. Background technique [0002] In recent years, my country's housing industry has grown rapidly, but the construction industry is still in a development stage with lagging construction technology and low production efficiency. The country's requirements for green and environmentally friendly buildings are gradually increasing. Traditional concrete structure house construction requires a lot of on-site pouring and long-term high-altitude operations, causing serious environmental pollution and low construction safety. Compared with concrete, steel structure has better properties such as tensile strength, earthquake resistance, and shorter construction period. Modularization and assembly are the development trend of my country's construction industry. The factory-like and mechanized potential of the mo...
