Exhaust tamping type steel bar truss floor support plate

Abstract

The invention discloses an exhaust tamping type steel bar truss floor support plate, and belongs to the field of building components, the exhaust tamping type steel bar truss floor support plate comprises a bearing bottom plate, the upper end of a steel bar suspension frame is slidably connected with a web moving exhaust steel bar, and the lower end of the bearing bottom plate is fixedly connected with a contraction flexible belt. Under the continuous action of the gravity of concrete, the blasting balls are gradually pressed and blasted, the bearing bottom plate and the abdomen-moving exhaust reinforcing steel bars are vibrated through the blasting force, concrete in the pouring process is effectively and continuously tamped, the concrete is assisted in exhausting, gas accumulation is effectively avoided, the compactness of the concrete is improved, the construction quality is improved, and the construction cost is reduced. The safety of the concrete wall in the later period is improved, under the cooperation of the pre-tensioning flexible arc pieces and the pre-tensioning supporting rods, concrete on the bottom layer can be expanded, the moving efficiency of concrete is improved, then concrete pouring is effectively assisted, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of building components, more particularly, to an exhaust tamping type steel truss floor deck. Background technique [0002] At the end of the 20th century, with the continuous development of steel structures, the construction speed of traditional cast-in-place slabs could not keep up with the construction speed of steel columns and beams, and the progress of the project affected the entire structure. Scaffolding, which deviates greatly from the on-site construction management requirements of the steel structure, does not match the entire construction process, so the steel truss is made of steel bars as the upper chord, lower chord and web member, and connected by resistance spot welding. [0003] Reinforced trusses use steel bars as the upper chord, lower chord and web members, and the truss connected by resistance spot welding is called steel bar truss. The frame deck is a kind of unsupported profiled composite deck...

Problems solved by technology

However, in the process of continuous pouring of concrete, due to the large flow range of the concrete, it can fully contact with the outside air, and it is easy to leave a large number of air bubbles inside the concrete, resulting in the formation of air holes inside the concrete after it is solidified and formed, reducing the compactness of the concrete wall. Sexuality, affecting the quality of building construction, thereby reducing the safety of the later concrete wall
