The invention discloses a profile steel truss double-skin wall structure and a construction method thereof. The profile steel truss double-skin wall structure comprises a main body structure, a double-skin wall structure unit and a cast-in-place concrete layer, the double-skin wall structure unit is transversely connected in a spliced manner; the cast-in-place concrete layer is cast in the double-skin wall structure unit; the double-skin wall structure unit comprises a first precast concrete slab and a second precast concrete slab; a group of profile steel trusses are transversely arranged between the first precast concrete slab and the second precast concrete slab at an interval in parallel; each profile steel truss is arranged vertically in the length direction, a chord member on one side of each profile steel truss is cast in the first precast concrete slab, the chord member on the other side of each profile steel truss is cast in the second precast concrete slab. Scaffold and formwork support procedures in traditional cast-in-situ technology are simplified, labor force is saved, potential safety risks caused by high-formwork support are avoided, and the technical problems thatexisting steel bar truss double-skin walls have small thickness and height not exceeding 4 m and existing double-skin wall structures have low overall rigidity and concrete lateral pressure resistanceare solved.
Description
technical field [0001] The invention relates to the field of building engineering structures, in particular to a steel truss double-skin wall structure and a construction method thereof. Background technique [0002] With the development of the information age, electronic products are becoming more and more abundant, and related industrial plants are constantly emerging; from the perspective of production technology, industrial plants need a large number of pools. thick. According to the traditional cast-in-place process, formwork and support systems need to be erected on both sides of the wall, and then concrete is poured in the space formed by the formwork. Subsequent work and formwork removal can only be carried out after the concrete reaches a certain strength. Due to the relatively high height of the structural wall, the construction process will involve high formwork and segmental pouring construction and maintenance issues. In addition to the wall construction of in...
