Abstract

The invention provides a web perforated box-type combined steel beam. The web perforated box-type combined steel beam comprises an upper flange, webs on the two sides and a bottom plate, wherein the webs are obliquely arranged, the two ends of the bottom plate extend out of the joints of the webs on the cross section, the section of a cavity formed among the upper flange, the webs and the bottom plate is trapezoidal or rectangular, a plurality of holes are formed in the web plates in the longitudinal direction at certain intervals, floor slab bottom steel bars and / or floor slab top steel bars can be inserted into the holes of the webs of the combined steel beams, and pipelines can be laid in the hollow cavity of the combined steel beam, and on-site trepanning reinforcement is not needed.

Description

technical field [0001] The invention belongs to the technical field of buildings and their construction, and relates to building components, in particular to a box-shaped composite steel beam with holes in the web. Background technique [0002] H-shaped steel beams and box-shaped steel beams are used for the beams of common steel-structured prefabricated houses, and the floors are generally built on H-shaped steel or box-shaped steel beams, which increases the indoor net height of the house and affects the indoor use space. The rationality of structural layout should be considered in the design of residential buildings in our country, emphasizing that the primary and secondary beams should not pass through the main living space such as the living room and living room, and the beams and columns should not be exposed. Residential building space should consider the applicability of the whole life cycle. [0003] Therefore, it is necessary to adopt hidden beam steel structure t...
