Problems solved by technology

[0003] However, in the formwork of the prior art, after the formwork is generally laid, it is necessary to lay ribbed steel cages between adjacent formworks and fix them. Therefore, the above-mentioned series of processes cause the formwork construction process to be cumbersome, and the formwork needs to be dismantled after pouring and molding. complex

Abstract

The invention relates to a new type of one-way dense rib formwork and an installation method, including a central movable formwork, a spliced ​​formwork, a horizontal underframe, a prefabricated steel cage and a prefabricated fixing piece. The upper middle of the horizontal underframe is equipped with a central movable formwork. A plurality of spliced ​​formworks are symmetrically installed on both sides of each central movable formwork, thereby forming a rib-free formwork group, and on the flanges between adjacent rib-free formwork groups, prefabricated fixtures are installed Prefabricated reinforcement cages to form a complete unidirectional ribbed formwork. The invention has simple structure, convenient transportation, can be assembled on site, can be reused, reduces construction cost, can simplify the construction process of full paving or strip paving and on-site binding of steel cages, and is convenient for splicing and fixing, and can be recycled for densely ribbed beams The floor is under construction.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to the technique of densely ribbed formwork, in particular to a one-way densely ribbed formwork and an installation method. Background technique [0002] In the past ten years, concrete ribbed beam floors have been widely used in construction projects in my country. This type of floor has the characteristics of low height of floor structure, light weight of floor, less amount of cast-in-place concrete and steel bars, fast construction period, suitable for large-span structures, etc., so it is widely used in large shopping malls, exhibition halls, cultural and sports High-rise commercial and public buildings such as halls, warehouse buildings, libraries, underground structures, teaching buildings, office buildings, etc., especially commonly used in structural types with large space, large span, and high headroom requirements. [0003] However, in the formwork of the prior art, af...
