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

Embodiment 1

[0044] Such as figure 1 and figure 2 As shown, the basement floor structure of this embodiment includes a flat plate 1 and a support 3 supported below the flat plate 1, and columns 2 perpendicular to the flat plate 1 are respectively arranged on the top of the flat plate 1 at positions corresponding to each support. A support pile 41 is provided below the support. Wherein, the projections of the columns 2 on the plate 1 are distributed in a rectangular array, the horizontal column spacing is a, and the vertical column spacing is b.

[0045] Specifically, the column 2 of this embodiment includes four columns 21, 22, 23, 24, and the projections of the columns 21, 22, 23, 24 on the plate 1 are located at the upper left, upper right, lower left and lower right of the plate 1 respectively. , the four form a rectangular array distribution. Among them, the lateral direction of the projection of two adjacent columns on the plate 1 (ie figure 1 The left and right directions in the...

Abstract

The invention relates to a basement bottom plate structure which comprises a flat plate and a plurality of supports arranged under the flat plate. A plurality of columns which are perpendicular to the flat plate are arranged on the portions, corresponding to all the supports, of the flat plate, and one or more support piles are arranged under the supports. According to the basement bottom plate structure, a beam structure is omitted, part of concrete materials and steel bar materials can be saved, the requirement for the earth rockfill excavation depth can be lowered, the construction difficulty of a support formwork and a waterproof layer of a basement bottom plate is lowered, the construction technology is optimized, and the construction difficulty and the workload are overall reduced.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a basement floor structure. Background technique [0002] In the basement floor, there are three stress states, which are 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 dynamic load state acting on the bottom surface of the floor. The 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 considered when calculating the force condition of the downward load, and only the self-weight of the downward load is considered when calculating the force ...
