Reserved cast-in-place with assembled monolithic concrete slab

Abstract

The invention belongs to the field of civil engineering, and particularly relates to a concrete structure and an assembly type building structure. A reserved cast-in-situ strip assembly integral concrete floor slab consists of two parts including a prefabricated concrete floor slab and a cast-in-situ concrete slab strip, wherein the slab prefabricated part comprises concrete, steel bars and embedded elements, and the steel bars and the embedded elements are arranged inside the concrete. For the prefabricated concrete floor slab, a groove or a slab joint with smaller size only needs to be reserved, the prefabrication rate of the floor slab is improved, the on-site wet construction can be reduced, the on-site installation speed is accelerated, the integrality of the floor slab is enhanced, meanwhile, pipelines are arranged in the reserved groove or slab joint, the thickness of the floor slab is reduced, the concrete consumption is reduced, further, the dead weight of the structure is reduced, and the effect caused by earthquake on the structure is reduced.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to an assembled building structure and a concrete structure. Background technique [0002] In the current prefabricated concrete structure, the laminated floor slab has been widely used due to its advantages of reducing the modulus, reducing wet work, improving work efficiency and shortening the construction period. However, in addition to the low prefabrication rate in the factory, the current laminated floor slabs still have the following problems: 1) In order to improve the rigidity and bearing capacity of the prefabricated slab and meet the needs of installation and construction, truss reinforcement is added; The thickness of the overlay layer. For this reason, the amount of concrete and steel bars has increased compared with the cast-in-place slab, the project cost has increased, and the self-weight of the structure has also increased the seismic action of the stru...

Problems solved by technology

However, in addition to the low prefabrication rate in the factory, the current laminated floor slabs still have the following problems: 1) In order to improve the rigidity and bearing capacity of the prefabricated slab and meet the needs of installation and construction, truss reinforcement is added; laminated layer thickness

For this reason, the amount of concrete and steel bars has increased compared with the cast-in-place slab, the project cost has increased, and the self-weight of the structure has also increased the seismic action of the structure.
