Problems solved by technology

Such a connection method causes the steel beam to occupy more indoor space and reduces the space utilization rate. Although the cross-sectional height of the steel beam is smaller than that of the concrete beam, the height of the steel beam is almost the same as that of the concrete beam after adding the thickness of the plate. , failed to give full play to the characteristics of light weight and high strength of steel structure
Therefore, the existing technology has the problem of low space utility rate

Abstract

The invention discloses a notched steel beam with a flange embedded in a floor, a floor structure and a construction method. The notched steel beam includes a web (1), and the upper and lower ends of the web (1) are respectively provided with an upper flange (2) and a lower flange. The flange (3); the upper flange (2) is provided with a gap (4); the flange is embedded in the floor including four rectangularly distributed floor columns (7), between adjacent floor columns (7) A steel beam (8) is provided, a laminated slab (9) is provided between two symmetrically distributed steel beams (8), a floor reinforcement (10) is provided above the laminated slab (9), and a concrete reinforcement is provided on the floor reinforcement (10). layer (11); the steel beam (8) is the notched steel beam whose flange is embedded in the floor slab; the construction method is to hoist the laminated slab into the notched steel beam in turn, lay the upper reinforcement layer and pour reinforced concrete in sequence. The invention has the characteristics of effectively improving the space utility rate.

Description

technical field [0001] The invention relates to a structure in which a steel beam flange is embedded in a floor slab, in particular to a notched steel beam with a flange embedded in a floor slab, a floor slab structure and a construction method. Background technique [0002] Steel structure buildings have the advantages of green environmental protection, recyclability and good seismic performance, which fully meet the standards of construction industrialization and green buildings. However, the current share of steel structures in the construction market is not high, especially residential buildings with large quantities and wide areas. , the share of steel structure is less than 1%, the main reason is that the high-strength and high-efficiency characteristics of steel structure have not been brought into play. The existing steel beam and floor slab are connected in the following manner: the steel beam is at the bottom, the floor slab is at the top, and the two are connected...
