Construction method of concrete slab based on welded steel mesh and cement pressure plate

Abstract

The invention relates to a concrete plate construction method based on a steel bar welded mesh and a cement pressure plate, and belongs to the technical field of building engineering. Two ends of a longitudinal steel bar of the steel bar welded mesh are made into two lengths with alternate intervals, one half extends into a support and the other half does not extend into the support. Under the condition that the steel bars of structural members of the support are bound, half of the steel bars at the bottom of the plate are not affected to penetrate into the support, and the industrial production of the steel bar welded mesh is not affected at the same time. One half of the transverse steel bar is arranged on the steel bar welded mesh, and the other half is arranged by binding the transverse steel bar on site, so that the steel bar welded mesh is not influenced to be placed at the bottom of the plate, and half of the steel bar at the bottom of the plate can be guaranteed to penetrate into the support. Through chamfering of the cement pressure plate and pouring of cast-in-situ concrete and cement slurry at the joint of the cement pressure plate, the thickness of the concrete protective layer of the steel bar at the bottom of the plate can be ensured to meet the requirements specified in the design specification. Compared with the current concrete composite slab technology, the concrete slab construction has higher industrialization degree, better quality and lower cost.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and relates to the industrialized construction of concrete slabs, in particular to a concrete slab construction method based on welded steel mesh and cement pressure plates. Background technique [0002] Concrete slabs are constructed in an industrialized way. The truss-reinforced concrete laminated slabs widely used at present, due to their heavy weight, complex production process, and difficult control of thickness and dimension accuracy, especially the excessive demoulding load makes it extremely easy to cause cracking. The quality is not easy to guarantee, and the production cost is relatively high. The total thickness of the truss reinforced concrete laminated slab is relatively large, and the general minimum thickness is 130mm, while the thickness of the cast-in-place concrete slab is usually 100mm, and the construction cost of the concrete laminated slab is relatively high....

AI Technical Summary

Problems solved by technology

However, the relationship between the lower part of the main rib steel truss and the non-demolition formwork of this utility model is poured into one, which is almost impossible to achieve in the actual production process, and it is even more impossible to realize industrial production. After it is completed, the strength of its free formwork cannot be satisfied at all.
