Abstract

The invention discloses a barrel formwork and a construction method thereof; the barrel formwork contains at least one barrel body and at least one end cap, wherein at least one barrel body is connected with one end cap; contact faces between barrel bodies and between the barrel body and the end cap comprise at least two butt joint surfaces and the butt joint surface that are not located on the same plane; the barrel formwork is a hollow tubular die body with a closed side face and two open ends; the cross section could be round, oval, rectangular or polygonoun; a barrel formwork construction concrete dense rib plate can prevent uplift pressure in concrete casting, thus saving the cost caused by anti-uplift measures; in addition, the barrel formwork is applied to a basement floor; the cavity can be filled by a raw condition adobe, thus using the adobe self weight and the adobe ground holding forced to resist uplift; the basement floor cross section height can be increased, thus greatly reducing the basement floor steel consumption and concrete consumption; the barrel formwork is simple in production, high in reliability, easy to construct, short in work period, low in cost, can be applied as the concrete dense rib plate waterproof material, is simple and suitable in construction method, and good in field application effect.

Description

technical field [0001] The invention relates to a concrete densely ribbed slab, in particular to a barrel form for a concrete densely ribbed slab and a construction method thereof, belonging to the technical field of building materials. Background technique [0002] It has been more than ten years for the concrete hollow floor slab to be constructed by filling the inner mold. Since the bottom of the filled inner mold of the hollow floor is designed with a concrete bottom plate, the filled inner mold must bear the buoyancy generated by the liquid concrete when pouring concrete. Therefore, the design The use of anti-floating steel bars and various fixing measures during construction is not only time-consuming and labor-intensive, but also increases self-weight, load, concrete and steel consumption. Therefore, it is meaningful to develop a new type of concrete ribbed slab with simple construction, short construction period and low cost. [0003] The roof panel is a structure e...
