Embodiment Construction

[0027] One of the embodiments shown in Figures 1 and 2 is a building floor member. According to the length × width of the floor, the cold-formed thin-walled lattice steel 1 with a C-shaped cross-section is arranged in parallel at intervals and combined with steel plates. The transition pieces 6 and self-tapping screws 5 are threaded to form a steel skeleton of cold-formed thin-walled lattice steel, and a template 3 connected to the steel skeleton, and the permanent template 3 has an insulating surface layer 4, which is poured into the template. Concrete2. The web surface of the cold-formed thin-walled grid steel with C-shaped cross-section is provided with positively and reversely arranged nearly triangular holes 7, and the periphery of each hole 7 has a curling edge 8 to form a reinforced flange. The two flanges form oblique U-shaped webs 9 between the holes, and nearly triangular pressure grooves 10 are arranged at the joints between the webs 9 and the flanges.

Abstract

The composite building construction member of cold bended thin wall lattice configuration steel and concrete features that it consists of steel skeleton comprising cold bended thin wall lattice steel section of different shapes arranged in certain intervals; permanent formwork fixed to the steel skeleton, of building plate and with heat insulating facing layer and decorative facing layer; connecting parts and transition parts. The composite building construction member may be floor slab, wall, beam or column member with steel skeleton(s), and deposited concrete. The present invention is durable, heat resistant, energy saving, light, efficient, low in cost and heat insulating, and has fast construction speed.

Description

technical field [0001] The invention belongs to building structural components, in particular to a cold-formed thin-walled lattice-structured steel-concrete composite building component in which a formwork is fixed on a cold-formed thin-walled latticed steel skeleton and a production process thereof. Background technique [0002] At present, the stressed components of building structures are mainly reinforced concrete components, including but not limited to plate components, beam and column components, and steel components. Reinforced concrete members and steel members basically form a reinforced concrete structure system and a steel structure system relatively independently. Steel structure and reinforced concrete structure are basically two relatively independent structural systems, and it is difficult to realize the combination of section steel and concrete. [0003] At present, steel bars in reinforced concrete structural members are used as the main structural materia...
