Concrete box type building module, modular building and construction method of modular building

Abstract

The invention discloses a concrete box type building module, a modular assembly type building and a construction method of the modular assembly type building. The problems that traditional building construction is large in labor demand, long in construction period, large in material waste, large in construction waste and serious in pollution, an existing fabricated building is high in cost and low in prefabrication rate, and an existing concrete modular building technology is incomplete and the structural safety is poor are solved. A prefabricated reinforced concrete structure box-type building module capable of bearing a room function is included. The modular building structure method is jointly achieved through vertical through type slurry anchor connecting cavities in a wall body, transverse connecting steel plates on the edge of a top plate, mortar bonding between modules, through snap-in grooves and the like. And the box-type building module is integrally duplicated by using the mold, so that the construction efficiency is improved. The modules are connected and constructed outside the box-type building modules, and the high prefabrication rate of decoration is guaranteed. Factory processing is achieved, and the building quality is reliable. Connecting components and main body steel bars are integrated, stress is scientific and reasonable, and fire resistance, shock resistance and durability are good.

Description

technical field [0001] The invention relates to the construction field, in particular to a prefabricated reinforced concrete box-type modular composite building. Background technique [0002] Human activities emit about 51 billion tons of greenhouse gases into the atmosphere every year. The ecological damage and environmental pollution caused by global warming have caused irreversible and catastrophic effects on people's lives and health. Carbon emissions in the entire life cycle of buildings account for a large proportion. According to statistics, in 2018, China's construction carbon emissions accounted for 51.3% of the country's carbon emissions, of which carbon emissions in the production stage of building materials accounted for 28.3%, and carbon emissions in the construction stage accounted for 1%. Phase carbon emissions accounted for 21.9%. [0003] The traditional on-site construction method requires a lot of labor, and the construction environment of the workers is ...

AI Technical Summary

Problems solved by technology

[0003] The traditional on-site construction method requires a lot of labor, the construction environment of the workers is harsh, and the safety is poor; the construction quality and construction period are greatly affected by factors such as construction personnel and weather

On-site construction wastes a lot of materials, construction waste, and serious pollution; the on-site construction part of the main structure leads to architectural decoration, pipelines, etc. that cannot be integrated with the building and prefabricated in the factory

[0004] The main problems that restrict the market promotion of prefabricated building technology are: the existing concrete prefabricated buildings, box-type modular buildings with steel structures and wooden structures are expensive in building materials, have many construction processes, and high labor costs

Some of these nodes need to be fixed by grouting at the edge of the indoor ground at the construction site, which affects the factory-like prefabricated decoration of the ground and the lower part of the wall
