Double-layer all-steel structure floor with embedded channel steel beams

Abstract

The invention discloses a double-layer all-steel structure floor slab embedded with a steel channel beam and belongs to floor slabs. The double-layer all-steel structure floor slab embedded with the steel channel beam is characterized by being mainly composed of beams, longitudinal beams, transverse ribs, auxiliary beams, upper purlines, lower purlines, inclined struts and steel panels. Equal angle steel is welded to the inner sides of the joints of the two ends of the front beam and the rear beam and the two ends of the left longitudinal beam and the right longitudinal beam respectively to form rectangular steel frames, the transverse ribs are evenly distributed and welded between the upper surfaces of lower wing plates of the left longitudinal beam and the right longitudinal beam, and the auxiliary beams are welded to the middle of the inner sides of webs of the front beam and the rear beam respectively. The upper purlines are evenly distributed and welded to the upper portions of the auxiliary beams between the inner sides of the webs of the front beam and the rear beam in a corresponding mode, and the lower purlines are evenly distributed and welded to the upper surfaces of the lower wing plates and between the transverse ribs of the inner sides of the webs of the front beam and the rear beam in a corresponding mode. The inclined struts are evenly distributed and welded between the corresponding upper purlines and the corresponding lower purlines, and the steel panels are laid on all the upper purlines. The double-layer all-steel structure floor slab embedded with the steel channel beam is safe and reliable in use and high in construction efficiency.

Description

technical field [0001] The invention belongs to floor slabs, in particular to a double-layer all-steel structure floor slab. Background technique [0002] Seeking an economical, practical, and efficient structural system has become the focus of steel structure application and research. The staggered truss structure system developed from the bending-resistant steel frame system is a new type of structural system that meets this demand. Research and promote this The structural system is in line with the development direction of my country's architectural structure. The staggered truss structure system is a new type of building steel structure evolved on the basis of the steel frame structure system. The system is basically composed of vertical and horizontal peripheral steel columns, plane trusses between columns, and floor slabs. The two ends of the planar trusses whose height is equal to the floor height and whose span is equal to the width of the house are supported on the ...

AI Technical Summary

Problems solved by technology

The two ends of the planar trusses whose height is equal to the floor height and whose span is equal to the width of the house are supported on the vertical and horizontal steel columns outside the house. There are no columns in the middle of the house, but the floor slab is cast on site after the steel columns and planar trusses on the same floor are installed. , not only reduces the construction efficiency, but also fails to reflect the concept of industrialization of construction and green buildings with a full life span
