Combined wall with angle steel keel combined with light concrete

Abstract

The invention discloses a combined wall with an angle steel keel combined with light concrete. The light concrete is foam concrete, ceramsite concrete, perlite concrete, polyphenyl granule concrete, coal ash concrete and the like. The angle steel keel is formed by connecting densely arranged angle steel sheet columns and square columns through a floor ring beam, a wall waist ring beam, a wall bracing truss and a screw or a bolt. The sheet column or the square column is formed from an angle steel chord member with a turned edge or not, a square (rectangular) pipe, an angle steel, a channel steel connecting piece or a stamped part through connection by means of a screw or a bolt or through bonding spot welding. The floor ring beam, the wall waist ring beam and the wall bracing truss are fabricated from square (rectangular) pipes and channel steels. The break of the angle steel chord member is formed from an angle steel jointing connecting piece through connection by using a screw or a bolt or through bonding spot welding. An angle steel guide rail is connected with a foundation ring beam chemically or through an embedded bolt. The sheet columns and the square columns are connected with the guide rail directly through a screw and a bolt or through bonding spot welding. The combined wall provided by the invention has the advantages of high bearing capability, simplicity in production and assembly, good fireproof and corrosive resisting performance, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to a building structure wall, in particular to a composite wall combining angle steel keels and lightweight concrete. Background technique [0002] Lightweight steel structure prefabricated houses have the advantages of light weight, good seismic performance, short construction period, energy saving and environmental protection, and high degree of industrialization. They were introduced to China from abroad in the 1980s and have broad application prospects. [0003] The traditional light steel keel system is assembled by structural panels (commonly used OSB panels) and light steel keels. Among them, the light steel keels are all connected by C-shaped steel through self-tapping screws. This kind of structural system has low keel rigidity, and the upper and lower wall columns are not directly connected, etc., and has not been widely promoted in my country. [0004] In recent years, Canada and China have developed a new lattice lig...

AI Technical Summary

Problems solved by technology

The lattice light steel keel system has high wall rigidity and high bearing capacity, but the design and on-site installation require professional teams to complete

[0005] In addition, whether it is the traditional light steel keel system or lattice light steel, the two sides of the wall keel are generally made of structural panels, which is easy to install, but it also brings some problems: the wall is not solid; the transportation cost is increased; The board seam needs special treatment; and the board seam is prone to cracks after the wall is plastered

[0006] To sum up, there is no light steel keel system with cheap cost, simple production and installation, high bearing capacity and good fire resistance in the market at present.
