[0002] Prefabricated stairs are one of the products of the development process of building industrialization. They are staircase components that are pre-processed and manufactured in the factory and then transported to the construction site for installation. Before hoisting the prefabricated stairs, it is necessary to place bolts in the corresponding reserved holes on the ladder beams that support the stairs according to the positions of the reserved bolt holes on the stairs and fix them by pouring; The patent application with the publication number CN213081834U discloses an L-shaped ladder beam template reinforcement and embedded bolt fixing integrated device, comprising two connecting pieces arranged vertically on the templates on both sides of the vertical opposite sides close to the length direction of the L-shaped ladder beam, both connecting pieces are provided with transverse long strip adjustment holes, the two connecting pieces are tightened and fixed by at least two tension bolts, two adjusting pieces arranged side by side are connected to the connecting piece on the outer side of the L-shaped ladder beam, the bottom of the vertical section of the inverted L-shaped bracket of the adjusting piece is adjustably fixed to the connecting piece along the length direction of the adjustment hole by a first bolt, the transverse section at the top of the bracket extends to the upper side of the L-shaped ladder beam ladder surface, the transverse section is provided with a long strip connection hole perpendicular to the length direction of the adjustment hole, and a round tube is adjustably fixed to the transverse section along the length direction of the connection hole by a second bolt; Since the concrete structure will produce a certain degree of shrinkage or expansion during the solidification process after pouring, the tension generated during the shrinkage or expansion process will affect the embedded position of the L-shaped bolts, causing deviation in the embedded position of the bolts, which in turn leads to reduced accuracy in the installation of the prefabricated stairs, affecting the construction progress and quality. The L-shaped ladder beam formwork reinforcement and embedded bolt fixing integrated device provided by this patent cannot effectively deal with the bolt position deviation caused by the shrinkage or expansion of the concrete structure. Reducing the deviation in the bolt fixing position is the key to solving the problem. Summary of the invention

The trapezoidal trigger block 412 is located inside the corner fixing frame 35. A contact plate 413 is fixedly connected to the back of the connecting rod 411. The contact plate 413 is located on the front of the L-shaped ladder beam 1. The contact plate 413 is located on the back of the front bottom frame 231. The back of the trapezoidal trigger block 412 is fixedly connected to the front of the sliding plate body 31 through a spring; The sliding link 42 is slidably connected to the top of the sliding support frame 3, and the bottom of the sliding link 42 is slidably connected to the top of the deformation trigger rod 41, which is used to transmit the changes in the concrete structure sensed by the deformation trigger rod 41. The sliding link 42 includes a sliding rod body 421, and the surface of the sliding rod body 421 is slidably connected to the inside of the circular through hole at the top of the corner fixing frame 35. The bottom of the sliding rod body 421 is rotatably connected to a linkage pulley 422, and the surface of the linkage pulley 422 is slidably connected to the top inclined surface of the trapezoidal trigger block 412; The rotating slide rod 43 is rotatably connected to the top of the sliding support frame 3, and is used to convert the vertical sliding of the sliding link 42 into rotation. The top of the support frame 32 is rotatably connected to the rotating slide rod 43, and the right side of the rotating slide rod 43 is rotatably connected to the top of the sliding rod body 421; A sliding fixing head 44 is slidably connected to the surface of the rotating slide rod 43 and is used to fix the top of the L-shaped bolt. The sliding fixing head 44 includes a sliding sleeve clamp 441. The sliding sleeve clamp 441 is located on the back side of the supporting frame 32. The sliding sleeve clamp 441 is slidably connected to the surface of the rotating slide rod 43. A threaded through hole is provided on the top of the sliding sleeve clamp 441. A hexagonal bolt is rotatably connected to the top of the threaded through hole of the sliding sleeve clamp 441. A movable sleeve head 442 is rotatably connected to the bottom of the sliding sleeve clamp 441. A circular blind hole is provided at the bottom of the movable sleeve head 442.

[0026] When in use, in Example 1, after the L-shaped bolt passes through the bolt limiting tube 36, the position of the sliding fixing head 44 is adjusted so that the sliding fixing head 44 is located directly above the bolt limiting tube 36. After determining the position, the sliding sleeve clamp 441 is fixed to the rotating slide rod 43 by tightening the hexagonal bolt, and then an elastic bushing 443 matching the diameter of the L-shaped bolt is selected and installed on the bottom of the movable sleeve head 442, and the top of the L-shaped bolt is inserted into the elastic bushing 443, and then the hexagonal bolt of the movable sleeve head 442 is tightened to complete the fixation, and the concrete pouring and solidification process in Example 1 is performed. During the process of solidification after the concrete is poured, the concrete will shrink or expand, and at the same time, the concrete structure of the L-shaped ladder beam 1 will be affected. The L-shaped bolt applies tension, which causes the concrete structure of the L-shaped ladder beam 1 to deform. This deformation drives the contact plate 413 to change together. The contact plate 413 drives the connecting rod 411 and the trapezoidal trigger block 412 to slide backward or forward, and then drives the vertical sliding of the sliding link 42 through the trapezoidal trigger block 412. The vertical sliding of the sliding link 42 drives the rotation of the rotating slide rod 43. While the rotating slide rod 43 rotates, since the L-shaped bolt is fixed by the concrete and clamped by the weight of the L-shaped bolt itself, the movable sleeve 442 and the sliding sleeve clamp 441 rotate slightly, driving the L-shaped bolt to move slightly in the opposite direction of the concrete tension, thereby offsetting the deviation caused by the concrete tension.
