Description

Technical Field

[0001] This utility model is a foundation pit column support structure, belonging to the field of building technology. Background Technology

[0002] One of the challenges of foundation pit construction is starting excavation before the structural design is finalized. After the foundation pit is excavated, the main pile foundation or beams and columns may need to be adjusted, which may cause the supporting columns to conflict with the main pile foundation or beams and columns. In the traditional method, in order to resolve this conflict, it is necessary to replace and remove the existing columns by means of underpinning to adapt to the structural changes.

[0003] Existing support columns inevitably suffer from complex structures, high construction requirements, and significant construction difficulties. While some have simple technical principles and low support costs, they have certain shortcomings in terms of quality control and safety reliability. For example, support columns are generally equipped with a base that supports both the column and the support column. Moreover, the column is usually poured first, followed by the support column. This results in a gap in the middle, allowing water from the foundation pit to enter the base, causing erosion and softening inside the base. Therefore, to address the above issues, a foundation pit column support structure is proposed. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a foundation pit column support structure to solve the existing problems.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a foundation pit column support structure, the structure of which includes a column and a crossbeam, the column being supported on the crossbeam, a support post being provided on one side of the column, two support posts being provided and a fixed beam connecting the two support posts, a base being provided at the bottom of the support post, a water-stop steel plate being provided in the inner cavity of the base, a support frame being provided on the water-stop steel plate, and the water-stop steel plate being connected to the inner cavity of the base through the support frame.

[0006] Furthermore, the water-stop steel plate is shaped like a roof and there are two water-stop steel plates, which are respectively located on the upper and lower sides of the middle of the base.

[0007] Furthermore, the base is provided with reserved reinforcing bars on its side wall, which are equidistantly and evenly distributed on the side wall around the base.

[0008] Furthermore, the fixed beam is also connected to an inclined support rod, the two ends of which are respectively connected to the support column and the fixed beam.

[0009] The beneficial effects of this utility model are:

[0010] A water-stop steel plate is installed inside the base to prevent water from entering the inner cavity of the base.

[0011] The inclusion of pre-reserved reinforcing bars increases the convenience of later processing and the overall structural integrity.

[0012] The load-bearing capacity of the fixed beam is reinforced by incorporating diagonal support rods. Attached Figure Description

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution for a foundation pit column support structure: its structure includes a column 1 and a crossbeam 2, the column 1 is supported on the crossbeam 2, a support column 3 is provided on one side of the column 1, there are two support columns 3 and a fixed beam 4 is connected between the two support columns 3, a base 5 is provided at the bottom of the support column 3, a water-stop steel plate 6 is provided in the inner cavity of the base 5, a support frame 7 is provided on the water-stop steel plate 6, and the water-stop steel plate 6 is connected to the inner cavity of the base 5 through the support frame 7;

[0022] The water-stop steel plate 6 is shaped like a roof and there are two water-stop steel plates 6, which are located on the upper and lower sides of the middle of the base 5 respectively.

[0023] The base 5 is also provided with reserved steel bars 8 on its side wall. The reserved steel bars 8 are evenly distributed on the side wall around the base 5.

[0024] The fixed beam 4 is also connected to an inclined support rod 9, the two ends of which are connected to the support column 3 and the fixed beam 4 respectively.

[0025] For example, when water enters the base 5 through the crack in the middle of the base 5, it will be blocked by the groove end of the water-stop steel plate 6, thus ensuring that the water will not enter the interior of the base 5.

[0026] By providing pre-reserved reinforcing bars 8 on the base 5, the pre-reserved reinforcing bars 8 can facilitate subsequent construction. For example, when carrying out the next foundation pit column replacement construction, the pouring construction can be carried out directly.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
