Problems solved by technology

In the beam-slab structure, since the load on the foundation beam is often too large, it is necessary to set the section size of the foundation beam to be larger to bear the load, resulting in a large amount of reinforcement for the foundation beam

Abstract

The invention relates to a building adopting a support-floor slab type basement structure, which comprises a flat slab and a plurality of supports arranged under the flat slab, a plurality of columns which are perpendicular to the flat slab are respectively arranged at positions respectively corresponding to each support above the flat slab, and one or more supporting columns are arranged under each support. Such a structure dispenses with a beam structure, consequently, not only can part of concrete material and reinforcing steel bar material be saved, but also the requirement on earth-rock excavation depth can be decreased and the difficulty of basement floor slab formwork and waterproof layer construction can be decreased, the construction technology is optimized, and the difficulty and workload of construction are decreased on the whole.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a building using a support-floor basement structure. Background technique [0002] In high-rise buildings and non-high-rise buildings, there are often basement structures. In the floor part of the basement structure, there are three stress states, namely, the downward gravity load state acting on the top surface of the floor, the upward water buoyancy state acting on the bottom surface of the floor, and the upward civil air defense dynamic load acting on the bottom surface of the floor State, the above three stress conditions may exist alone, two or three simultaneously. When these three stress conditions exist at the same time, they may cancel each other out, but in the design of the bottom plate, only the most unfavorable state to the bottom plate is considered when calculating the force conditions. That is to say, the counteracting effect of the upward load is not consider...
