Light steel house structure

Abstract

The invention discloses a light steel house structure. The light steel house structure comprises a light steel floor system and a light steel wall body, wherein the light steel wall body comprises a wall body inner plate, a light steel wall body framework and a wall body outer plate; the light steel wall body framework comprises vertically arranged light steel columns and transversely arranged cross beams; the light steel columns are transversely distributed at intervals and integrally connected with each other by the cross beams; one face of the light steel wall body framework is connected with the wall body outer plate while the other face of the light steel wall body framework is connected with the wall body inner plate; the light steel floor system comprises a floor beam and a floor plate; the floor beam is intersected with the light steel wall body and fixedly connected with the cross beams; and the floor plate is laid on the floor beam; in the light steel house structure disclosed by the invention, because the light steel columns distributed at intervals are integrally connected with each other by the cross beams and the floor beam is fixedly connected with the cross beams to form the framework structure of the house so as to provide the main bearing force, the house structure system has the advantages of simplicity in connection, quickness and convenience in construction, good mechanical performance, stability and reliability, and the bearing force of the system cannot be affected even though the system is affected with damp.

Description

technical field [0001] The invention relates to a building structure system, in particular to a light steel house structure. Background technique [0002] The light steel house is to use thin-walled steel to build the structural skeleton of the house. This structure has the advantages of thin wall, low material consumption, light weight, convenient and quick installation, and good seismic performance. [0003] The traditional method is to use C-shaped steel as the basic material, and then use C-shaped steel to form structural components such as columns, walls, and beams, and further build the structural skeleton of the entire house. However, the C-shaped steel itself is an open thin-walled steel, so it is easy to cause local instability of the thin plate under the action of force; It is very troublesome to do a layer of external insulation outside the skeleton. [0004] Due to these problems of C-shaped steel, in recent years, a small truss composed of light steel rectangu...

AI Technical Summary

Problems solved by technology

However, there are still many problems in this system, such as: installing a thermal insulation layer outside the structural surface layer, the construction is troublesome, and the thickness of the wall is increased; the OSB board used as the structural surface layer has poor weather resistance and fire resistance, once the OSB board is damp , its bearing capacity will be greatly reduced and cannot provide the effect of structural slabs; the OSB board wall greatly limits the application of interior and exterior decoration materials; the floor connected by the U-shaped groove floor is cut off unstable and the upper chord of the floor beam is easy Compression buckling; problems such as low bearing capacity of a single rectangular tube floor connection and easy buckling of the upper chord of the floor beam
