Assembling self-bearing die of ribbed floor

Abstract

The invention relates to an assembling self-bearing die of a ribber floor. The assembling self-bearing die comprises an inner core and an outer die, wherein the outer die comprises a bottom die, and a baffle arranged on the outer edge of the bottom die; the bottom die comprises a grid structure where multiple bottom die cavities are formed; the inner core is respectively arranged in each bottom die cavity, and a casting gap is retained between the baffle and the inner core and between the inner cores, and formed by the space surrounded by the baffle, the bottom die and the inner core; a steel bar truss structure is arranged on the bottom die and fixedly arranged in the casting space and comprises a planar grid structure, and steel bars crossing over the planar grid structure; the height of the inner core is less than that of the steel bar truss structure. The assembling self-bearing die is large in construction load bearing capacity, high in integral rigidity and good in anti-seismic property.

Description

technical field [0001] The invention relates to the field of building construction, in particular to an assembled self-supporting mold for a ribbed floor slab. 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, one is cast-in-situ concrete ribbed roofs, and the other is a ...

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
