Adjacent two corner external supports 101 have a spacing, the adjusting assembly is arranged between the external support assemblies and is used for adjusting the spacing between the adjacent corner external supports 101, so as to adjust the size of the external support assembly.

[0048] With reference to Figure 1 , the adjusting assembly comprises a fixing seat 201, a sliding seat 202, an adjusting rod 203, an adjusting rope 204 and a retractor 205.

[0049] With reference to Figure 1 , the fixing seat 201 and the sliding seat 202 are fixedly connected at the end of the corner outer support 101, and the fixing seat 201 and the sliding seat 202 are arranged in pairs at the end of every two adjacent corner outer supports 101. One end of the adjusting rod 203 is fixedly connected to the fixing seat 201, and the other end passes through the sliding seat 202 and is in sliding fit with the sliding seat 202. A distance-expanding compression spring 206 is arranged between the adjacent fixing seat 201 and the sliding seat 202, and the distance-expanding compression spring 206 is sleeved on the adjusting rod 203.

[0050] With reference to Figure 1 , one end of the adjusting rope 204 is fixedly connected to the adjusting rod 203, and the other end is connected to the retractor 205. The retractor 205 is fixedly connected to the corner outer support 101. The setting directions of the fixing seat 201 and the sliding seat 202 on the opposite sides of the outer support assembly are consistent, and the adjusting ropes 204 on the opposite sides of the outer support assembly are commonly connected to one retractor 205. In addition, in order to facilitate the movement of the adjusting rope 204, a plurality of guide wheels 114 are connected to the corner outer support 101.

[0051] With reference to Figure 2 , the retractor 205 comprises a mounting seat 207 and a retraction shaft 208.

[0052] With reference to Figure 2 , a rotating cavity 209 is formed on one side of the mounting seat 207, and a limiting cavity 210 is formed on the side of the mounting seat 207 away from the rotating cavity 209. A bearing ring 211 is fixedly connected in the rotating cavity 209, and the retraction shaft 208 passes through the bearing ring 211 and is rotatably connected in the rotating cavity 209. In addition, in order to facilitate the rotation of the retraction shaft 208, an internal hexagonal hole 212 is formed on the end of the retraction shaft 208 close to the opening of the rotating cavity 209.

[0053] With reference to Figure 2 , an internal meshing gear 213 is fixedly connected to the end of the retraction shaft 208 located at the opening of the rotating cavity 209, a ejection compression spring 214 is arranged between the bearing ring 211 and the internal meshing gear 213, and the ejection compression spring 214 is sleeved on the retraction shaft 208. A lock-up gear ring 215 is fixedly connected at the opening of the rotating cavity 209, the inner side wall of the lock-up gear ring 215 is provided with teeth, and the outer side wall of the internal meshing gear 213 is provided with teeth. In the absence of external force, the internal meshing gear 213 and the lock-up gear ring 215 are located in the same plane, and they are meshed with each other to limit the rotation of the retraction shaft 208.

[0054] With reference to Figure 2The end of the take-up shaft 208 away from the inner gear 213 penetrates the wall thickness of the mounting base 207 and enters the limiting cavity 210, and the end of the take-up shaft 208 entering the limiting cavity 210 is fixedly connected with a limiting nut 216. The limiting nut 216 has a limiting function and can prevent the take-up shaft 208 from being separated from the mounting base 207.

[0055] With reference to Figure 2 The take-up shaft 208 is fixedly connected with a partition ring 217 on the shaft between the bearing ring 211 and the limiting nut 216, the outer side wall of the mounting base 207 is provided with a wire inlet hole 218 communicating with the rotating cavity 209, and the wire inlet hole 218 is provided with one on each of the two opposite outer side walls of the mounting base 207, and the two wire inlet holes 218 are located on the two sides of the partition ring 217 respectively.

[0056] The two adjusting ropes 204 on the opposite sides of the outer support assembly respectively enter the rotating cavity 209 through the wire inlet hole 218 and are connected to the take-up shaft 208. The partition ring 217 can separate the two adjusting ropes 204 to prevent the two adjusting ropes 204 from being entangled with each other and causing the adjusting rope 204 to be knotted.

[0057] When adjusting the spacing between the adjacent corner outer support members 101, the worker first presses the take-up shaft 208 downward by using the hexagonal wrench, so that the inner gear 213 is separated from the locking gear 215, and the restriction on the take-up shaft 208 is released.

[0058] When the spacing between the adjacent corner outer support members 101 is too large, the worker rotates the take-up shaft 208 by using the hexagonal wrench, the adjusting rope 204 is wound on the take-up shaft 208, the adjusting rope 204 drives the adjusting rod 203 to move, and the adjusting rod 203 drives the fixed seat 201 to move, so as to realize the effect of adjusting the spacing between the adjacent corner outer support members 101 to be small. At this time, the expansion spring 206 is in a compressed state. When the spacing between the adjacent corner outer support members 101 is too small, the worker reversely rotates the take-up shaft 208 by using the hexagonal wrench, and the adjusting rope 204 is separated from the take-up shaft 208. At this time, the elastic force of the expansion spring 206 is released, so as to realize the effect of adjusting the spacing between the adjacent corner outer support members 101 to be large.

The entering opening 110 is in the same direction as the mounting opening 105, and the entering opening 110 and the clamping opening 109 form an “L” shape.

[0066] With reference to Figure 1 and Figure 5 One side of the clamping plate 107 is provided with a guide rod 111, and the entering opening 110 is located at the end of the clamping opening 109 away from the guide rod 111. A guide hole for the sliding of the guide rod 111 is arranged on the inner side wall of the receiving opening 104. The compression spring 108 is sleeved on the guide rod 111, and the compression spring 108 is pressed between the clamping plate 107 and the inner side wall of the receiving opening 104.

[0067] Reference Figure 1 And Figure 5 An auxiliary rod 112 is fixedly connected to the side wall of the buckle plate 107 away from the guide rod 111, and a sliding hole for the auxiliary rod 112 to slide is formed in the inner side wall of the containing hole 104. The sliding cooperation of the auxiliary rod 112 and the sliding hole improves the stability of the buckle plate 107 during movement. A push rod 113 is fixedly connected to the outer side wall of the buckle plate 107 to facilitate the movement of the buckle plate 107.

[0068] After the spacing between each corner outer support 101 is adjusted, the installation of the pre-buried assembly is performed. The worker first moves the buckle plate 107 by using the push rod 113 to make the entrance hole 110 communicate with the installation hole 105, and then slides the rod 303 of the pre-buried rod 302 into the containing hole 104 along the entrance hole 110 and the installation hole 105, at this time the end cap 304 of the pre-buried rod 302 is located on the side of the buckle plate 107 away from the pre-buried plate 301, then the push rod 113 is loosened, at this time the elastic force of the top pressing spring 108 is released, which promotes the movement of the buckle plate 107 to make the clamping hole 109 clamp the rod 303, and at the same time, after the buckle plate 107 moves, the entrance hole 110 is located away from the installation hole 105, and the pre-buried assembly is limited on the corner outer support 101.

[0069] After the pre-buried rod 302 of each side of the outer support assembly is installed, the worker begins to install the pre-buried plate 301. Before installing the pre-buried plate 301, the worker opens a gap on the pre-buried plate 301 for the pre-buried rod 302 to pass through, and then the worker successively adheres the pre-buried plate 301 to each side of the outer support assembly. When the pre-buried plate 301 of each side is adhered, the worker fixes each pre-buried plate 301 to each other by welding.

[0070] The worker installs the mold into the reserved hole position of the bridge, and at the same time, connects and fastens the pre-buried rod 302 and the steel structure of the power well by using a steel wire, and then pours concrete to form a power well structure. At this time, the pre-buried plate 301 and the pre-buried rod 302 are integrated with the concrete structure, and the enlarged head 305 of the pre-buried rod 302 is partially located in the concrete, which improves the anti-pulling performance of the pre-buried assembly, and in turn improves the stability of the pre-buried assembly in the concrete.

[0071] Finally, the worker moves the buckle plate 107 to make the installation hole 105 and the entrance hole 110 communicate, and then pulls out the mold along the direction of the installation hole 105 and the entrance hole 110, at this time the area between each pre-buried plate 301 is the reserved hole of the bridge.
