Description

Steel bar support for super-thick raft

Technical Field

The utility model relates to the technical field of steel bar supports, in particular to a steel bar support for an ultra-thick raft plate.

Background

Raft board, a concrete slab in the foundation engineering, the foundation is under the board, and the column, wall, etc. are arranged on the board. It is also called a raft board since it floats on the soil. The foundation type adopted by the building is closely related to the type of foundation soil and the distribution condition of soil layers. In engineering design, the geological conditions are often encountered, and the rock-soil layers under the basement bottom plate are weathered residual soil layers, completely weathered rock layers, strongly weathered rock layers or weathered soft rock layers, so that a natural foundation is possibly adopted as a building foundation. The basement of the high-rise building is usually used as an underground parking garage, and excessive inner walls are not allowed to be arranged on the building, so that the use of box type foundations is limited; the raft foundation can not only give full play to the bearing capacity of the foundation and adjust the uneven settlement, but also meet the space use requirement of the parking garage, thereby becoming a more ideal foundation type. The main construction types of the raft foundation are a flat plate type raft foundation and a beam plate type raft foundation, and the flat plate type raft foundation is widely applied to high-rise buildings due to simple construction.
