[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0020] Example 1: A modular clamping installation structure of a curved aluminum plate for rail transit, see Figures 1 to 4 ,include;

[0021] A plurality of arc-shaped mounting plates 2 installed between two sides of a tunnel wall 1 and an arc-shaped aluminum plate body 3 arranged between two adjacent arc-shaped mounting plates 2, wherein two adjacent arc-shaped mounting plates 2 among the plurality of arc-shaped mounting plates 2 are provided with an arc-shaped slot 21 at opposite ends, the inner cavities of the plurality of arc-shaped slots 21 are slidably connected with an arc-shaped baffle 22, a plurality of springs 23 are installed at one end of the inner cavities of the plurality of arc-shaped slots 21, and the plurality of springs 23 are equidistantly distributed in the arc-shaped slots 21, and the other ends of the plurality of springs 23 are fixedly connected with the arc-shaped baffle 22, the length of the arc-shaped aluminum plate body 3 is less than the distance between the inner walls of the two opposite arc-shaped slots 21, and the length of the arc-shaped aluminum plate body 3 is greater than the distance between the two adjacent arc-shaped mounting plates 2;

[0022] A connecting rod 4 is installed at the middle of the top of the arc-shaped mounting plate 2, and a connecting block 41 is installed on the top of the connecting rod 4. Fixing bolts 42 are passed through the connecting blocks 41 on both sides of the connecting rod 4. When working, the fixing bolts 42 are connected to the top of the inner side of the tunnel wall 1, so that the arc-shaped mounting plate 2 is hoisted in cooperation with the connecting rod 4, and then one end of the arc-shaped aluminum plate body 3 is inserted into the arc-shaped slot 21, and then the arc-shaped baffle plate 22 is pushed toward the inner side of the arc-shaped slot 21 to compress the spring 23 so that the other end of the arc-shaped aluminum plate body 3 corresponds to the other arc-shaped slot 21, and then the hand releases the push of the arc-shaped aluminum plate body 3, so that the elastic force of the spring 23 pushes the arc-shaped baffle plate 22 to drive the arc-shaped aluminum plate body 3 to move so that the arc-shaped aluminum plate body The other end of the body 3 is placed in another arc-shaped groove 21. Since the length of the arc-shaped aluminum plate body 3 is smaller than the distance between the inner walls of the two opposite arc-shaped grooves 21, and the length of the arc-shaped aluminum plate body 3 is larger than the distance between the two adjacent arc-shaped mounting plates 2, the arc-shaped baffles 22 on both sides of the arc-shaped aluminum plate body 3 cooperate with the spring 23 to limit the arc-shaped aluminum plate body 3 between the two adjacent arc-shaped mounting plates 2. When disassembly is required, the arc-shaped aluminum plate body 3 is pushed to one side to compress the spring 23 while causing one end of the arc-shaped aluminum plate body 3 to detach from the arc-shaped groove 21, so that the arc-shaped aluminum plate body 3 can be disassembled, thereby eliminating the need to disassemble and assemble the arc-shaped aluminum plate body 3 through bolts, thereby further improving the efficiency of disassembly and assembly of the arc-shaped aluminum plate body 3.

[0023] For further information, see Figure 1, a cushion block 43 is installed at one end of the connecting block 41 away from the connecting rod 4. One end of the cushion block 43 is adapted to the inner arc of the tunnel wall 1. Through the arrangement of the cushion block 43, the stability of the contact between the connecting block 41 and the top of the inner cavity of the tunnel wall 1 is increased, thereby improving the stability of the installation of the arc-shaped mounting plate 2, and further improving the stability of the installation of the arc-shaped aluminum plate body 3.

[0024] It should be noted that, referring to Figure 4 , sealing strips 5 are installed at both ends of the arc-shaped mounting plate 2 and both ends of the arc-shaped aluminum plate body 3, and the sealing strips 5 are elastic and are used to increase the sealing performance between the arc-shaped aluminum plate body 3 and the inner side of the tunnel wall 1 after installation.

[0025] It should be noted that, referring to Figure 3 , the elastic force of the spring 23 is greater than the frictional force between the arc-shaped baffle 22 and the arc-shaped card slot 21, and is used to ensure that the elastic force of the spring 23 can push the arc-shaped baffle 22 to reset after the spring 23 is compressed, so as to ensure the smooth installation of the arc-shaped aluminum plate body 3.
