[0033] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent and easy to understand, the specific embodiments of the utility model are described in detail below with reference to the drawings.

[0034] In the following description, specific details are set forth in order to provide a thorough understanding of the utility model. However, the utility model can be practiced in a variety of ways other than those described herein, and skilled in the art can make similar generalizations without departing from the connotation of the utility model. Therefore, the utility model is not limited to the specific embodiments disclosed below.

[0035] As Figures 1 to 3 shown, the support member for the side wall reconstruction of the subway station of the utility model includes upper pad 1 and lower pad 2, and upper pad 1 and lower pad 2 are fixedly connected through a plurality of support plates. The support plate includes two first support plates 3 arranged in parallel and second support plate 4 located between the two first support plates.

[0036] In the embodiment, the first support plate 3 and the second support plate 4 are arranged along the vertical direction. The two ends of the second support plate 4 are fixedly connected with the middle part of the first support plate 3 on both sides, so that the cross section of the second support plate 4 after being fixedly connected with the first support plate 3 on both sides is H-shaped. The top surface of the first support plate 3 and the second support plate 4 is fixedly connected with the upper pad 1, and the bottom surface of the first support plate 3 and the second support plate 4 is fixedly connected with the lower pad 2. In the embodiment, the top surface of the first support plate 3 and the second support plate 4 and the upper pad 1, and the bottom surface of the first support plate 3 and the second support plate 4 and the lower pad 2 are fixedly connected by using the welding mode of bevel welding.

[0037] In order to improve the stability and torsional performance of the whole support member, ensure that the support member can still play a load bearing effect in the case of small size, the first support plate 3 between the two sides is provided with a stiffened plate. The stiffened plate includes vertical stiffened plate 5 and horizontal stiffened plate 6, the intersecting vertical stiffened plate and horizontal stiffened plate are fixedly connected by welding. A plurality of vertical stiffened plates 5 are arranged between the two first support plates 3, and the vertical stiffened plates 5 are arranged in the horizontal direction of the second support plate 4, and the vertical stiffened plates 5 are fixedly connected with the second support plate 4, the upper pad plate 1 and the lower pad plate 2, in the embodiment, the fixed connection is realized by welding, and the welding form adopts double fillet weld. In the embodiment, the vertical stiffened plates 5 are symmetrically fixed on both sides of the second support plate 4.

[0038] The vertical stiffened plate 5 mainly plays a supporting role. Therefore, in the present application, the thickness of the vertical stiffened plate is not less than 20mm, and preferably, the thickness is 20-30mm. The spacing between the adjacent two vertical stiffened plates and the spacing between the vertical stiffened plate and the adjacent first support plate is not more than 250mm.

[0039] At the same time, a plurality of horizontal stiffened plates 6 are arranged between the two first support plates 3, and the horizontal stiffened plates 6 are arranged in the vertical direction of the second support plate 4, and the horizontal stiffened plates 6 are fixedly connected with the first support plate 3 and the second support plate 4, in the embodiment, the fixed connection is realized by welding, and the welding form adopts double fillet weld. In the embodiment, the horizontal stiffened plates 6 are symmetrically fixed on both sides of the second support plate 4.

[0040] The horizontal stiffened plate 6 mainly plays a connecting role, so that the whole support member becomes a whole structure. Therefore, the thickness of the horizontal stiffened plate is not specially required, and preferably, the thickness is 15-20mm. The spacing between the adjacent two horizontal stiffened plates is not required.

[0041] The working process of the support member for transforming the subway side wall is as follows. First, several small holes are opened in the top of the side wall at the middle position, the width of the small hole is 0.8m, the height of the small hole is the same as the height of the ring beam at the hole top, and the spacing between the adjacent small holes is 2-3m.

[0042] Then, the support member described in the utility model is arranged in the small hole, such as Figure 4The support member is in interference fit with the small hole, that is, the support member supports the small hole, and the upper pad plate 1 of the support member is in close contact with the top surface of the small hole, the lower pad plate 2 of the support member is in close contact with the bottom surface of the small hole, and the support member supports the top of the side wall. In this embodiment, the height of the support member is 1000mm, the length is 790mm, and the width is 300mm, so the size and weight are relatively small, which is convenient for transportation. The support member described in the application can replace the long and large steel used in the existing side wall reconstruction process, and solves the transportation problem of the long and large steel in the subway station that has been put into operation.

[0043] Next, the remaining concrete in the range of the cast-in-place beam column is chipped off, as shown in Figure 5 The construction of the beam column steel bar binding is started, the support member is bound in the beam column steel bar, the steel bar at the beam column joint can be bound at one time, and the overall stress performance of the joint is effectively improved.

[0044] During the beam column steel bar binding process, the support member 8 described in the application is fixed in the beam column steel bar 7, that is, the support member is fixed between adjacent steel bars. In the actual construction process, in order to ensure the fixed connection between the support member and the steel bar, the support member and the steel bar are fixed and connected by spot welding. Thus, a whole structure is formed between the beam column steel bar 7 and the support member 8, the overall performance of the structure is improved, and the problem of many beam column steel bar joints and poor overall performance in the existing side wall reconstruction process is solved. The structure between the beam column steel bar and the support member after binding is shown in Figure 6 After the overall beam column steel bar binding is completed, the overall beam column steel bar is poured.

[0045] Finally, the remaining concrete in the range of the opening is chipped off, and thus the reconstruction of the side wall is completed, and the structure of the reconstructed side wall is shown in Figure 7 .
