Efficient and low-consumption combined formwork system and construction method thereof

Abstract

The invention discloses an efficient and low-consumption combined formwork system and a construction method thereof. A formwork comprises an early-removing portion and a non-early-removing portion, the early-removing portion comprises early-removing formwork bodies (2), the non-early-removing portion comprises non-early-removing formwork bodies (11), the early-removing formwork bodies (2) and the non-early-removing formwork bodies (11) are alternately arranged on the lower side of a concrete floor slab (1) at intervals in rows, the lower sides of the early-removing formwork bodies (2) are supported on a cross rod (3) through back edges (4), the lower sides of the non-early-removing formwork bodies (11) are supported on vertical upright rods (5), and the two ends of the cross rod (3) are in butt joint with rabbets of wedge-shaped connecting key female heads (13) through wedge-shaped connecting key male heads (14) to form a supporting system. According to the efficient and low-consumption combined formwork system and the construction method thereof, the current situations of high investment, high consumption and low efficiency of a current formwork system can be changed, the environment-friendly formwork system that the formwork bodies can be removed early and a scaffold can be quickly assembled and removed can be obtained through development and use of the efficient and low-consumption combined formwork system, and accordingly the aims of reducing construction consumption and improving social benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of formwork in construction engineering, and relates to a high-efficiency and low-consumption combined formwork system and a construction method thereof. Background technique [0002] Reinforced concrete cast-in-place components are the main part of today's building structures, and the formwork system is an indispensable support and mold for its forming. At present, the formwork support frame commonly used in domestic formwork systems is fastener-type steel pipe scaffolding. The formwork used It is wood plywood. Fastener-type steel pipe scaffolding is slow in erection speed, low in safety performance, large in randomness, and low in turnover efficiency, and the crossbar, back corrugated and formwork of the scaffold cannot be dismantled early, and the turnover period of materials is long, which not only increases the burden of material use, but also occupies Higher construction costs. Contents of the inven...
