At the same time, when the slider 305 moves to the other end of the arc-shaped slide 303, the rotating link 308 and the transmission link 304 will rotate. In order to facilitate the pouring of the continuous wall, the connecting plate 302 and the mounting plate 311 are set to a quick assembly splicing mode.

[0025] The working principle of the present invention is as follows: first, the rectangular support frame 206, the T-shaped sheet metal 207 and the transverse sheet metal 208 need to be connected together with the steel cage frame 100 by bolts. The rectangular support frame 206, the T-shaped sheet metal 207 and the transverse sheet metal 208 can form a firm rectangular support structure, thereby reinforcing the support and seismic resistance of the steel cage frame 100. By fixing the frame 201, the reinforcement bracket 202 and the side protection sheet metal 203, the concrete at the edges of the steel cage frame 100 on both sides can be protected. On the one hand, the support of the steel cage frame 100 is strengthened, and on the other hand, the steel The corners of the cage frame 100 play a protective role. The limit blocks 301 on the lower surfaces of the connecting plate 302 and the mounting plate 311 are inserted into the mounting sheet metal 204. Then, the limit blocks 301 and the mounting sheet metal 204 can be firmly connected together by installing bolts 209. The connecting plate 302 and the mounting plate 311 are arranged horizontally up and down. The central axis 306 of the connecting plate 302 will move into the mounting groove 315. Then, the push rod 321 can be pushed to drive the pull rod 322 and the push rod 320 to rotate around the rotating seat 319. When one side of the push rod 320 contacts the extension plate 318, the extension plate 318 can be driven. The mounting ring 316 of the plate 318 rotates around the rotating seat 317, and then the mounting ring 316 can install the central axis 306 between the mounting ring 316 and the mounting groove 315, thereby completing the splicing of the connecting plate 302 and the mounting plate 311, and then assembling the two steel cage frames 100. At the same time, the pulling rod 322 on one side can push the clamping plate 325 to move horizontally along the limiting groove 314, and one end of the clamping plate 325 will fix the plug 309 in the limiting slot 312 to achieve the fixation of the rotating connecting rod 308. After the connecting plate 302 and the mounting plate 311 are spliced, pull the rod 322 to push the clamping plate 325 to move horizontally along the limiting groove 314. The push-pull handle 307 can move by rotating the connecting rod 308 and the transmission connecting rod 304, so that the slider 305 moves along the arc-shaped slide groove 303. When the slider 305 moves to one end of the arc-shaped slide groove 303, the rotating connecting rod 308 and the transmission connecting rod 304 will be parallel, and the two steel cage frames 100 will form a parallel state, thereby realizing the docking of the two steel cage frames 100. At the same time, when the slider 305 moves to the other end of the arc-shaped slide groove 303, the rotating connecting rod 308 and the transmission connecting rod 304 will rotate, and then the connecting plate 302 and the mounting plate 311 will rotate around the central axis 306 to realize the folding of the steel cage frame 100. The folding is to facilitate the adjustment of the angle of the steel cage frame 100 and to facilitate the placement of prefabricated components between the steel cage frames, thereby speeding up construction efficiency.
