Self plate-bearing type steel bar mesh support combined template and construction method thereof

Abstract

The invention provides a self plate-bearing type steel bar mesh support combined template and a construction method thereof. The self plate-bearing type steel bar mesh support combined template comprises a self plate-bearing type steel bar mesh support unit, wherein the self plate-bearing type steel bar mesh support unit comprises a plurality of rows of longitudinal steel bar trusses, a plurality of rows of transversely-distributed steel bars and a detachable template body, and one single row of longitudinal steel bar truss is composed of an upper string bar, two lower string bars and a corrugated bar arranged between the upper string bar and the lower string bars. One single row of transversely-distributed steel bar is fixed with the longitudinal steel bar trusses, and the detachable template body is arranged on the lower portion of the self plate-bearing type steel bar mesh support unit and fixedly connected with the self plate-bearing type steel bar mesh support unit. A self plate-bearing type steel bar mesh support is combined with the detachable template body so as to develop the self plate-bearing type steel bar mesh support combined template with the space stress system, the self plate-bearing type steel bar mesh support combined template can independently bear concrete dead loads and additional loads in the process of construction, the self plate-bearing type steel bar mesh support combined template has strong integral rigidity, no supporting or small supporting of the concrete building horizontal structural template is achieved, supporting materials and using labor are greatly saved, and the construction efficiency is improved.

Description

technical field [0001] The invention relates to the field of concrete structure building construction, in particular to a self-supporting slab-type reinforced grid frame composite formwork and a construction method thereof. Background technique [0002] At present, horizontal structural formwork projects in my country's construction industry generally adopt bent frame support, supplemented by wooden squares and plywood or formwork. Its technological principle provides support for the bottom formwork by setting up a bent support system to meet the requirements of bearing capacity and deformation during the construction stage. Its support forms include: Φ48×3.5 scaffold fastener erection, door frame scaffold erection, tower bracket, adjustable support column erection and other methods. [0003] However, this horizontal structural formwork engineering technology has its own defects: [0004] (1) High construction cost [0005] Building a full house of scaffolding requires a ...

AI Technical Summary

Problems solved by technology

[0004] (1) High construction cost

[0005] Building a full house of scaffolding requires a lot of materials, and at the same time requires a lot of labor, and the construction cost is high;

[0006] (2) Low construction efficiency

[0007] Due to the need to set up the bent frame support and lay the bottom formwork, the workload is huge, labor-intensive and time-consuming, the construction efficiency is low, and the construction period is affected;

[0008] (3) Poor construction environment

[0013] (2) It is difficult to carry ou
