a building frame

Abstract

The invention discloses a building framework. The building framework comprises house columns, girders and longitudinal beams, wherein the house columns are stand columns arranged vertically; each girder is a beam positioned between every two adjacent house columns and arranged transversely; and each longitudinal beam is a beam positioned between every two adjacent house columns and between every two adjacent girders and arranged longitudinally. The building framework is characterized in that the house columns, the girders and the longitudinal beams all adopt sleeved profiles with closed cross sections; and each sleeved profile is formed by rotating two long-strip-shaped members at an angle of 180 degrees along the cross section and sleeving the long-strip-shaped members in a staggered manner, wherein the long-strip-shaped members are formed by cold-state rolling of thin-walled steel plates and have identical sizes and shapes as well as equal cross sections. Compared with the prior art, the building framework has the advantages that the building framework has the characteristics of modular design, standardized manufacturing and fabricated construction, so that the labor intensity of building construction can be reduced, building rubbishes can be reduced, the construction cycle can be shortened, and the building construction efficiency can be improved; and the building framework is suitable for the fields of barracks, guesthouses, offices, warehouses, factories, bridges and the like.

Description

technical field [0001] The invention relates to a building frame, in particular to a building frame using nested profile members, which can be widely used in modular building combinations in military and civil construction fields. Background technique [0002] Due to the rapid development of social modernization technology and economy, traditional metal frame buildings are increasingly unable to meet the needs of development. As a result, a modular building frame has developed rapidly at home and abroad. Among them, the existing invention patent "Tubular Structure and Modular Building Combination" with the patent number of 02808261.3 is about the modular building structure. The building combination structure of roof beams and roof columns, such as building components such as roof beams and roof columns, adopts a combination of a thick-walled "H"-shaped hot-rolled section steel and two pieces of thick-walled "C"-shaped hot-rolled section steel. profile member, the "C" shaped...

AI Technical Summary

Problems solved by technology

[0004] First, due to the use of thicker hot-rolled section steel to construct the composite body, the consumption of raw materials is relatively large; second, the composite molding of hot-rolled sections with different geometric shapes and structural dimensions without equal cross-section requires a large amount of labor and production. Low efficiency and high production cost; third, due to the relative combination of one piece of "H" steel and two pieces of "C" steel, it is necessary to use multiple positioning devices and fastening bolts, and to perform the above three through multiple welding processes. The combined positioning and assembly between the hot-rolled profiles requires high-precision production and processing equipment and detection methods, which will greatly increase the complexity and processing difficulty of the production process; Section characteristics and structural stiffness, which in turn affect the comprehensive mechanical properties of the building frame
