Description

Floor slab and building

Technical Field

The utility model relates to the technical field of constructional engineering, in particular to a floor slab and a building.

Background

The existing cast-in-situ floor slab can be divided into a plate type floor slab, a beam plate type floor slab and a beam-free floor slab according to the structure, and is formed by pouring concrete and a brick die. In the process of pouring the floor, the difficulty is very high during construction, so that the requirements on technicians and constructors are very strict.

In addition, the bottom film of the cast beam floor slab is very complex to manufacture, and the brick die consumption is very large, so that the time is longer in the process of preparing materials. Meanwhile, when the cast-in-place beam floor slab is constructed, the steel bars are used as main concentration points, and once the construction is not good, some complex concrete is easy to generate a honeycomb state, so that the construction difficulty is very high, if the construction is carried out in a rainy season, the phenomenon of water accumulation is easy to generate, and a great amount of time is required to drain water.

Therefore, the existing cast-in-situ floor slab has long construction period and high labor cost, and the concrete and the brick die can also cause the increase of the load of the building, and simultaneously, a large amount of non-renewable resources are also used.
