Construction method for thermal insulating sandwich concrete external wall panel with steel beams and steel columns

Abstract

The invention relates to a construction method of a sandwich thermal insulation concrete outer wall panel, steel beams and steel columns, comprising the following steps: hoisting the steel columns in place, popping up the steel columns, steel beam axes and wall installation control lines on the floor; Hoisting of thermal insulation concrete external wall panels; steel beams of sandwich thermal insulation concrete external wall panels and steel column corbels are connected by bolts; upper sandwich thermal insulation concrete external wall panels reserve gaps and reserved steel plates on the sides of the gaps and lower sandwich thermal insulation concrete external wall panel steel beams The lifting lugs are connected; the openings at the joints between steel beams and steel columns are sealed; the openings at the steel beam lifting lugs at the bottom of the sandwich insulation concrete exterior wall panels are sealed. The construction method of the sandwich thermal insulation concrete external wall panels, steel beams and steel columns of the present invention solves the problems of the horizontal connection between the prefabricated sandwich thermal insulation external wall panels and the steel columns and the vertical connection of the steel beams, and the on-site installation and construction speed of the external wall panels It is faster than traditional masonry, reduces on-site wet work, protects the environment, and is conducive to on-site civilized construction.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method of a sandwich thermal insulation concrete exterior wall board, steel beams and steel columns. Background technique [0002] In the prior art, in the construction of a steel structure residence, the vertical steel columns are installed first, then the horizontal steel beams are connected, and finally the steel structure is formed as a whole, and the external wall maintenance structure mainly adopts aerated concrete blocks and steam The installation of compressed aerated concrete slats (ALC), the horizontal connection between the aerated block masonry and the steel column is connected by welding steel bars on the steel column; the connection of the autoclaved aerated concrete slab is mainly in the steel The angle steel is welded on the column, and the hook bolts are used to connect the slats and the angle steel. The on-site construction workload is large, the ...

[0002] In the prior art, in the construction of a steel structure residence, the vertical steel columns are installed first, then the horizontal steel beams are connected, and finally the steel structure is formed as a whole, and the external wall maintenance structure mainly adopts aerated concrete blocks and steam The installation of compressed aerated concrete slats (ALC), the horizontal connection between the aerated block masonry and the steel column is connected by welding steel bars on the steel column; the connection of the autoclaved aerated concrete slab is mainly in the steel The angle steel is welded on the column, and the hook bolts are used to connect the slats and angle steel. The on-site construction work is heavy, the process is complicated, and the construction speed is slow.
