Novel modular assembled lower-layer thin-walled cold-formed steel floor module

Abstract

Provided is a novel modular assembled lower-layer thin-walled cold-formed steel floor module. The floor module is formed by connecting A, B, C, and D four kinds of sub-units. The four kinds of sub-modules use a truss girder and profiled steel sheet and foam cement composite floor system. A concave (called a wide beam) thin-walled cold-formed steel section or a thin-walled cold-formed steel section which can be spliced into a concave shape (called a narrow beam) in a pairwise manner are used in the upper boom and the lower boom of the truss girder. A C-shaped section is used in the web plate of the truss girder. A surface plate comprises foam cement, a reinforcing mesh, and a cold-bending steel plate from top to bottom in sequence. The wide beam, the narrow beam, and the surface plate are assembled together, so as to form A, B, C, and D four kinds of floor sub-units. Through expanding, combining, and splicing the four kinds of floor sub-units, modular assembling of floor systems in different dimensions is realized. The floor module system combines modulization, factorization, and assemblage, and realizes factory-like production and fast assembling on site. The floor module is a green and environmentally-friendly structural system.

Description

Technical field: [0001] The invention relates to a novel modularized assembled low-rise cold-formed thin-walled steel floor module, which belongs to the field of assembled houses. Background technique: [0002] According to the statistics of the China Iron and Steel Association, my country's steel production exceeded 700 million tons in 2011, ranking first in the world in steel production. The steel structure building area in the United States accounts for more than 50% of the total building area, Japan accounts for 80%, and my country's less than 4%. . China, as a big steel production country in the world, lags far behind in the development of steel structure housing. [0003] In recent years, domestic scholars have done some research on the research of prefabricated houses, but they are not in-depth, and the construction speed is only slightly reduced, and the rapid installation of steel structures has not really been realized, reflecting the advantages of steel structures...
