Few-support steel wire mesh reinforced microporous concrete non-dismantling bottom formwork and construction method thereof

Abstract

The invention discloses a few-support steel wire mesh reinforced microporous concrete non-dismantling bottom formwork and a construction method thereof. The formwork is composed of high-strength light-weight microporous concrete, a phi4@100 reinforcing mesh and alkali-resisting glass fibber gridding cloth; the bottom formwork is used as a bottom formwork when a concrete floor slab is poured; due to the good mechanical property, the formwork erecting requirement can be met through a small number of supporting pieces; then the bottom formwork is connected with floor slab steel bars in a binding mode by being matched with steel core plastic connecting pieces and clamping plate hook rib connecting pieces; and therefore, a few-support steel wire mesh reinforced microporous concrete non-dismantling bottom formwork support system can be formed. The bottom formwork disclosed by the invention has the characteristics of light weight, high strength, heat preservation, fire prevention, sound insulation, permeability resistance, economy and attractiveness, can replace bamboo plywood and steel formworks for existing cast-in-place floors, can perform rapid construction, improve the construction efficiency and reduce the construction cost, and solves the engineering problems that the existing cast-in-place floors need secondary heat preservation, and too many supporting pieces, various procedures, low dismantling efficiency and the like exist due to formwork erecting.

Description

technical field [0001] The invention belongs to less-supported steel wire mesh reinforced microporous concrete non-demolition-free bottom formwork for cast-in-situ concrete floor slab construction. The main body has the same service life, which meets the requirements of building energy-saving design and the use of concrete permanent bottom formwork. Background technique [0002] With the rapid development of prefabricated buildings in my country and the shortage of labor and the increase of construction costs, the realization of prefabricated rapid construction is currently the most effective solution. Bamboo plywood and steel formwork are used in most of the current cast-in-place concrete floor slab bottom formwork, which requires a large number of supports during construction, and the bottom formwork needs to be removed after the concrete has been poured and the concrete meets the curing requirements. The construction is cumbersome. It consumes a lot of manpower and finan...
