AI Technical Summary
In the construction of underground garages, it is difficult for the existing technology to efficiently deal with deep buried residual piles, resulting in high excavation costs and affecting the construction progress. In addition, the frame columns have problems of uneven settlement and sensitivity when dealing with settlement.
Design an underground garage frame column structure that avoids residual piles. By setting auxiliary pile foundations and pile foundation support platforms on both sides of residual piles, and setting cushion layers and foundation pull beams at the bottom of the support platforms, the frame columns are placed in the pile holes. A gap is formed to avoid residual piles, reduce the treatment requirement for residual piles, and enhance overall foundation stability through foundation pulling beams.
It can shorten the construction period without excessive treatment of residual piles, improve settlement uniformity, reduce the sensitivity of the superstructure to settlement, and form a complete force transmission system.

Abstract
Description
Technical Field
[0001] The utility model relates to a frame column structure, in particular to an underground garage frame column structure for avoiding residual piles, and belongs to the technical field of building construction. Background Art
[0002] In the construction process of underground garages or other places, it is very easy to have residual piles left by demolished buildings in the past. In the existing technology, the residual piles need to be excavated, but due to the deep burial depth of the residual piles, the excavation cost is high, which affects the construction progress and causes great difficulties for projects with tight construction schedules. At the same time, the frame columns used in existing underground garages have problems such as uneven settlement and poor sensitivity of the upper structure to settlement when dealing with settlement conditions. Therefore, further improvements are needed. Utility Model Content
[0003] The purpose of the utility model is to solve the above-mentioned shortcomings and provide an underground garage frame column structure that avoids residual piles, which does not require excessive processing of the residual piles, improves settlement uniformity, and improves sensitivity to settlement.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0005] A frame column structure for an underground garage for avoiding residual piles comprises a residual pile body; auxiliary pile foundations are arranged on both sides of the residual pile body; a pile foundation bearing platform is arranged on the auxiliary pile foundation; and a frame column is arranged on the pile foundation bearing platform.
[0006] Furthermore, foundation tie beams are respectively arranged on both sides of the pile foundation cap; the foundation tie beams extend along the horizontal direction of the pile foundation cap.
[0007] Furthermore, a cushion layer is provided at the bottom of the pile foundation cap; the cushion layer and the bottom of the pile foundation cap are separated from each other; and the auxiliary pile foundation passes through the cushion layer and is connected to the pile foundation cap.
[0008] Furthermore, the cushion layer has 45° chamfers on both sides; a pile hole is opened in the pile foundation cap; and the frame column is arranged in the pile hole.
[0009] Furthermore, the cushion layer is higher than the upper surface of the residual pile body.
[0010] Furthermore, a gap is formed between the frame column and the pile hole.
[0011] The utility model has the following beneficial effects: when using this solution, when dealing with the original residual piles, it is only necessary to cut them below the cushion layer, without excessive processing, which greatly shortens the construction period and reduces costs. It is a better choice for engineering projects with tight construction periods. At the same time, the pile foundation cap can both support and transmit and ensure the stability of the superstructure. The foundation tension beams are arranged in both directions along the pile foundation cap to strengthen the integrity of the foundation, reduce uneven settlement, eliminate or reduce the sensitivity of the superstructure to settlement, play an overall coordination role between the caps, and then form a complete force transmission system. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 It is a schematic diagram of the structure of the utility model when viewed from above.
[0014] In the figure: 1 is the residual pile body, 2 is the auxiliary pile foundation, 3 is the pile foundation cap, 4 is the frame column, 5 is the foundation tension beam, and 6 is the cushion layer. DETAILED DESCRIPTION
[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0016] The terms used herein, including technical and scientific terms, have the same meaning as those generally understood by those skilled in the art, unless the terms are defined differently. It should be understood that the terms defined in commonly used dictionaries have the same meaning as those in the prior art.

[0018] A frame column structure of an underground garage for avoiding residual piles comprises a residual pile body 1; auxiliary pile foundations 2 are arranged on both sides of the residual pile body 1; pile foundation caps 3 are arranged on the auxiliary pile foundations 2; and frame columns 4 are arranged on the pile foundation caps 3.
[0019] Furthermore, foundation tie beams 5 are respectively provided on both sides of the pile foundation cap 3 ; the foundation tie beams 5 extend along the horizontal direction of the pile foundation cap 3 .
[0020] Furthermore, a cushion layer 6 is provided at the bottom of the pile foundation cap 3 ; the cushion layer 6 and the bottom of the pile foundation cap 3 are separated from each other; the auxiliary pile foundation 2 passes through the cushion layer 6 and is connected to the pile foundation cap 3 .
[0021] Furthermore, the cushion layer 6 has 45° chamfers on both sides; a pile hole is opened in the pile foundation cap 3; and the frame column 4 is arranged in the pile hole.
[0022] Furthermore, the cushion layer 6 is higher than the upper surface of the residual pile body 1 .
[0023] Furthermore, a gap is formed between the frame column 4 and the pile hole.
[0024] Working principle: the existing frame column 4 is not in direct contact with the residual pile body 1, but auxiliary pile foundations 2 are newly made on both sides of the residual pile body 1. The newly made auxiliary pile foundations 2 are not directly connected to the existing frame column 4, but are connected through the pile foundation cap 3. The foundation tension beam 1 cooperates with the pile foundation cap 3 to avoid the residual pile body 1, so that the frame column 4 transmits force to the pile foundation cap 3, and then the pile foundation cap 3 transmits force to the auxiliary pile foundation 2. The frame column 4 can directly avoid the residual pile body 1, and the residual pile body 1 does not need to be processed too much, and only needs to be cut below the cushion layer 6.
[0025] Finally, it should be noted that the above embodiments are only for illustrating the technical solution of the utility model rather than limiting it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
