Rib-free beam mold box sandwiched reinforced concrete floor system

Abstract

A rib-free beam mold box sandwiched reinforced concrete floor system comprises a double-layer reinforcement cage and a light insulation board mold box, wherein the double-layer reinforcement cage is composed of reinforcement meshes arranged on the upper layer and lower layer respectively. The light insulation board mold box is formed by shearing four right angles of a square mold box and is in central symmetry. A hole is formed in the central point of the light insulation board mold box. The rib-free beam mold box sandwiched reinforced concrete floor system has the advantages that by adopting floors of the system, a large span can be realized and the self weight of structural members can be lowered; integral on-site casting is adopted in the construction technology of the floors, the construction processes are simplified compared with common beam slab structures, the height of floor systems can be lowered, and the heat insulation effect and the sound insulation effect are good.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a reinforced concrete floor slab system sandwiched by a ribless beam formwork box. The floor slab is suitable for realizing a relatively large span while reducing the self-weight of structural members. Background technique [0002] In the entire structural system formed by the floor, columns and foundations, the floor is an indispensable part. Ordinary floors can only be about 6 meters. When the span of the floor is greater than 6 meters, generally a force-bearing girder will be installed in the middle of the floor to form a beam-slab floor to reduce the calculated span of the floor. Setting the floor girder will cause the floor The increase of the height will cause uneconomical consequences. If the load-bearing girder is not installed, the self-weight and reinforcement of the floor slab will be greatly increased, which will also greatly increase the cost of th...

AI Technical Summary

Problems solved by technology

For example, the thin-walled tube hollow floor has the disadvantage that it can only bear force along the rib direction, and its calculation model is a one-way slab. Under the condition that all four sides have support conditions, it is obviously unreasonable for the floor to bear force in one direction; The series of floors such as stiffeners, cavity and large slabs cannot be separated from the existence of rib beams. For example, thin-walled boxes, laminated boxes, boxes, and mold box-filled floor structures are all beams as stress members, and slabs are stressed as a whole. The effect is not great, and it is difficult to form the whole floor at one time
