[0023] The following is combined with Figure 1-9 This application is described in further detail.

[0024] The present application discloses a support fixture for segmented preloading of an arch ring of an arch bridge, Figure 3 , including a positive baffle 1, which is used to prevent the sandbags used for pre-compression from sliding down. During the pre-compression process, the sandbags are accumulated on the front of the positive baffle 1. The positive baffle 1 is assembled by plugging together a plurality of sub-plates 8. The drawings of this embodiment only list a positive baffle 1 composed of 5 sub-plates 8. For arch bridges of different widths, different numbers of sub-plates 8 can be used for assembly.

[0025] Reference Figure 7 、 Figure 8 and Figure 9 , which are three different shapes of sub-board 8, among which the left and right ends use Figure 7 and Figure 8 The corresponding shapes are Figure 9The corresponding shapes are convenient for disassembly and assembly, and improve adaptability.

[0026] Reference Figure 1 and Figure 2 The back of the positive baffle 1 is fixedly connected with a fixing rod 2. In this embodiment, there are two fixing rods 2. The fixing rods 2 are welded and fixed to the back of the positive baffle 1, thereby reinforcing the connection strength between the sub-plates 8. The back of the fixing rod 2 is welded with a vertical rod 3. There are multiple vertical rods 3 and they are evenly distributed in a row, which further improves the connection strength and also facilitates the setting of the support rod 4.

[0027] Reference Figure 1 and Figure 4 The support rod 4 is welded to the back of the vertical rod 3, and its number is the same as the vertical rod 3. During use, in order to improve the fixing effect, the bottom of the positive baffle 1, the vertical rod 3 and the support rod 4 can be welded and fixed to the bracket below to ensure that the tooling does not move, thereby ensuring the stability of the sandbag.

[0028] Further, refer to Figure 4-Figure 6 , limiting grooves 5 are opened on both sides of the front of the front baffle 1, and the front baffle 1 is connected with the side baffle 6 through the limiting groove 5. The limiting groove 5 is convex, and one side of the side baffle 6 is fixedly connected to the limiting block 7. The limiting block 7 is adapted to the limiting groove 5. By inserting the limiting block 7 into the limiting groove 5, the side baffle 6 can be quickly installed, which is convenient for limiting the side of the sandbag, so as to improve the fixing effect of the sandbag, thereby improving the pre-compression effect.
