Ribbed supporting-free unit formwork device and mounting method

Abstract

The invention relates to a ribbed supporting-free unit formwork device including an unit formwork frame, formwork shells, steel reinforcement cages, and fixing parts. The unit formwork frame is of a grid-shaped grille, the formwork shells are laid on the upper surface of the unit formwork frame successively, the fixing parts are evenly distributed on the steel reinforcement cages at intervals, thesteel reinforcement cages are arranged on the flanging edges of the formwork shells, and the steel reinforcement cages, the unit formwork frame, and the formwork shells are connected to form a wholethrough fixing parts. The invention further provides a mounting method of the ribbed supporting-free unit formwork device, so that the mounting is convenient, the assembly can be carried out on the scene, the recycling utilization can be achieved, the construction costs can be lowered, the device can simplify construction processes of full laying or strip laying and steel reinforcement cage binding on the scene, the splicing and fixing are convenient, and the device can be circularly utilized in ribbed beam floor cap construction.

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 branch-free unit formwork device 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] There are mainly two types of ribbed roofs, o...

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-resistant 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.
