Abstract

The invention relates to a section steel partially wrapped concrete column and steel beam joint structure and a construction method thereof, and relates to the technical field of structural engineering. The section steel partially wrapped concrete column and steel beam joint structure comprises closed H-shaped steel, recycled concrete is poured in the closed H-shaped steel, and a cross-shaped steel frame is arranged on the closed H-shaped steel. The construction method of section steel partially wrapped concrete column and steel beam joint structure comprises the following specific steps thatstep 1, a circular section cross steel rod is welded and fixed into the closed H-shaped steel; and step 2, four I-shaped beams are placed at the upper end of the closed H-shaped steel in a centring and flat mode. According to the section steel partially wrapped concrete column and steel beam joint structure and the construction method thereof, the welding work can be completed in a factory, the bolt assembly can be adopted in the field, the construction speed and quality are greatly improved, the recycled concrete makes use of waste concrete, and the properties of fire prevention, waterproofing and corrosion prevention are achieved while protecting the environment.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a joint structure and a construction method of partially wrapped concrete columns and steel beams by section steel. Background technique [0002] In a broad sense, structural engineering refers to all artificial structures on the earth's surface or in the shallow crust. In a narrow sense, structural engineering mainly refers to industrial and civil buildings. In civil engineering, structural engineering mainly includes masonry engineering, reinforced concrete engineering, and structural hoisting engineering. and steel structure engineering. [0003] The current joint structure of concrete columns and steel beams needs to be installed on site in the actual construction area, which is not convenient for factory welding and assembly in advance, and the efficiency of the assembly process is low, which is not conducive to improving the construction speed and quality. T...
