Description

Technical Field

[0001] The utility model relates to the field of building technology, in particular to a double-column deformation joint structure communicating with a basement. Background Art

[0002] Building structures often deform due to external factors such as temperature changes, foundation settlement and earthquakes. Pre-reserved expansion joints can effectively reduce the damage of such deformation to building structures. If expansion joints are set in the basement, there will be a greater risk of water leakage. The risk of basement leakage is often reduced as much as possible from the perspective of reducing the number of expansion joints in the basement and increasing the spacing between expansion joints. The number of expansion joints in the basement is often less than that in the superstructure. Therefore, in actual projects, there are situations where the basement has no expansion joints but the superstructure has expansion joints at the same position on the plane. The ordinary double-column expansion joint is a common expansion joint. Its method is simple, but it is easy to cause eccentricity of the structural foundation on both sides of the expansion joint. Utility Model Content

[0003] The utility model aims to solve the deficiencies of the prior art and provides a double-column deformation joint structure communicating with basements, which not only embodies the advantage of the simple construction of the double-column deformation joint, but also effectively avoids the eccentricity of the structural foundations on both sides of the deformation joint.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0005] A double-column deformation joint structure connected to a basement, comprising an underground concrete column, wherein a low-side concrete structure is arranged on the left side and the top of the underground concrete column, and a high-side concrete structure is arranged on the right side and the top of the underground concrete column;

[0006] The low-side concrete structure includes a low-side above-ground concrete column connected to the top of the underground concrete column, and the low-side concrete structure also includes a plurality of upper and lower layers of low-side concrete beam-slab structures connected to the side walls of the low-side above-ground concrete column and the side walls of the underground concrete column;

[0007] The high side concrete structure includes a high side above-ground concrete column connected to the top of the underground concrete column, and the high side concrete structure also includes a plurality of upper and lower layers of high side concrete beam-slab structures connected to the side walls of the high side above-ground concrete column and the side walls of the underground concrete column;

[0008] Expansion joints are provided between the low-side ground concrete columns and the high-side ground concrete columns.

[0009] The top elevation of the underground concrete column is consistent with the ground height.

[0010] Vertical full-length steel bars are built into the connections between the low-side above-ground concrete columns, the high-side above-ground concrete columns and the underground concrete columns.

[0011] Horizontal reinforcement stirrups are provided at the connections between the low-side above-ground concrete columns, the high-side above-ground concrete columns and the underground concrete columns.

[0012] The beneficial effects of the utility model are as follows: the utility model is applicable to the situation where no deformation joint is arranged in the basement but deformation joint is required in the upper structure at the same position on the horizontal plane; the structure is simple and the eccentricity of the structural foundation on both sides of the deformation joint is effectively avoided.
