A branch-free assembled formwork device and construction method for a densely ribbed floor

Abstract

The invention relates to a non-branched assembled formwork device for densely ribbed floors, which includes a support frame and a prefabricated formwork, the prefabricated formwork includes two first unit formworks and a second unit formwork, and one of the two first unit formworks The space is connected by the buckle cover type fixing parts on both sides of the second unit formwork to form a complete prefabricated formwork, and the prefabricated formwork is installed on the support frame to form a complete branch-free assembled formwork. The present invention also proposes a construction method of a branch-free assembled formwork device for densely ribbed floors. The present invention has a simple structure and is easy to install, can be assembled on site, can be reused, reduces construction costs, and can simplify full or strip paving. The construction process of disassembly and assembly, and through the support of the supporting frame, the formwork frame of the underframe and the steel cage, greatly increased the self-load of the formwork device.

Description

technical field [0001] The invention belongs to the technical field of construction, and relates to dense-rib formwork technology, in particular to a dense-rib floor support-free assembled formwork device and a construction 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] There are mainly two types of ribb...

AI Technical Summary

Problems solved by technology

The construction of ordinary reinforced concrete cast-in-place beam and slab structures has high technical requirements for workers, high labor intensity, high wood consumption, easy deviation of beam cross-sectional dimensions, poor seismic performance, the need to use a lot of scaffolding, a large amount of construction waste, and fire resistance time. Shorter, poor fire resistance and other issues

Moreover, it is cumbersome and time-consuming to bind the reinforcement cage between the formwork on site.
