[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] Example 1

[0037] Existing station buildings can be expanded to improve the operational capacity of railway lines and make travel more convenient. After the structure of the new station building is assembled (or temporarily) it is connected to the existing structure by jacking to achieve the expansion of the existing station building.

[0038] Reference Figure 2 and Figure 3 There is an existing platform 400 below the top-pushing route of the structure 100 of the new station building, and an existing concrete column 401 is set on the existing platform 400. Figure 2 and Figure 3 It can be seen that the second-stage structure being pushed includes not only the structure 100 of the new station building, but also the guide beam 201 located at the front end of the structure 100 of the new station building.

[0039] This embodiment provides a temporary support frame used in the jacking of an existing station building expansion. Figure 1 The temporary support frame is fixedly connected to the existing concrete column 401 set up on the existing platform, including:

[0040] A temporary guide beam support frame, used to support the guide beam 201;

[0041] Temporary main structure support frame, used to support the main structure 100 of the new station building;

[0042] Wherein, the guide beam temporary support frame is erected above the main structure temporary support frame.

[0043] In this embodiment, the guide beam temporary support frame and the main structure temporary support frame are detachably connected. Figure 2 As shown), the guide beam 201 at its front end can be removed (as shown Figure 3 As shown), the structure 100 and guide beam 201 of the newly built station building can then continue to be pushed forward.

[0044] It can be seen that in this embodiment, the existing concrete columns on the existing platform 400 are used for support during the jacking process, and the temporary support frame for the guide beam and the temporary support frame for the main structure are built on the existing concrete columns on the existing platform 400. During the jacking process, the guide beam and the steel structure of the newly built station building are lifted to reduce deformation and improve the jacking accuracy. By cleverly utilizing the existing structure, the engineering workload and time are saved, which is a significant improvement.

[0045] Furthermore, the temporary support frame for the guide beam is directly arranged above the temporary support frame for the main structure, so there is no need for an overly large operating platform, and interference with the operating line is avoided while achieving the function.

[0046] Moreover, in this embodiment, the existing platform 400 is further used when constructing the temporary guide beam support frame and the temporary main structure support frame, and the temporary guide beam support frame and the temporary main structure support frame are connected to the existing concrete columns through the embedded steel plates of the existing concrete columns of the existing platform 400. In this technical solution, the temporary guide beam support frame and the temporary main structure support frame can increase stability by connecting with the embedded steel plates of the existing concrete columns, and the existing concrete columns can also be supported and reinforced by the temporary guide beam support frame and the temporary main structure support frame.

[0047] In this embodiment, the temporary support frame of the main structure includes:

[0048] The first support frame 303 is connected to the existing concrete column 401 through the embedded steel plate of the existing concrete column 401 of the existing platform 400;

[0049] An operating platform 306 is provided on the first supporting frame 303;

[0050] The slideway beam has a length set along the jacking direction, on which a slideway 304 is set in the same direction as the jacking direction, and a sliding cylinder 301 is set on the slideway 304. During jacking, the alternating support of the two sliding cylinders 301 and the position change of the two sliding cylinders along the jacking direction can help the structure 100 of the newly built station building move forward.

[0051] In this embodiment, the guide beam temporary support frame comprises:

[0052] A second support frame 305, the slideway beam and the slideway 304 pass through the bottom of the second support frame 305;

[0053] The lifting cylinder 302 is arranged on the second support frame 305. The extension distance of the cylinder rod of the lifting cylinder 302 is determined according to the deformation of the guide beam 201, and is used to lift the guide beam 201 upward. If the height of the structure being pushed shows that its deformation is too large, the cylinder rod of the lifting cylinder 302 extends upward to lift the guide beam to reduce the deformation.
