[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Reference Figure 1-4 The large-span precast staircase vertical mold shown includes a base plate 1 and a track 2. The track 2 is provided on the left outer wall of the base plate 1, and a fixed mold 8 is provided on the right side of the top surface of the base plate 1. A fixing member 3 is slidably connected on the track 2, and the right end of the fixing member 3 is connected to a movable mold 9. In order to control the lateral sliding of the movable mold 9 on the base plate 1, a moving component is provided between two sets of adjacent tracks 2. The distance between the movable mold 9 and the fixed mold 8 is controlled by the moving component. In order to prevent the fixed mold 8 and the movable mold 9 from separating when concrete is injected, the fixed mold 8 and the movable mold 9 are fixed and limited by a quick-connect mechanism.

[0022] As one embodiment of this example, the moving component is connected between two sets of tracks 2 by a reinforcing beam 4, and a telescopic push cylinder 5 is provided on the outer wall of the reinforcing beam 4. The telescopic end of the telescopic push cylinder 5 is provided with an end block 6, and the end block 6 is a rectangular block. A connecting rod 7 is provided on the end face of the end block 6, and the other end of the connecting rod 7 is connected to the movable mold 9. Through the above structure, the movable mold 9 can be driven to slide on the base plate 1.

[0023] As one embodiment of this invention, the quick-connect mechanism comprises: a movable seat 10 on the top surface of the movable mold 9, and a fixed seat 11 on the top surface of the fixed mold 8; a movable hole 101 and a fixed hole 111 are respectively provided on the end faces of the movable seat 10 and the fixed seat 11; a connecting rod 12 is rotatably connected within the movable hole 101; a limiting hole 112 with a convex cross-section is provided on the inner top surface of the fixed hole 111; and a plug 16 is slidably connected within the limiting hole 112. To enable the plug 16 to push downwards autonomously, a limiting rod 17 with a T-shaped cross-section is provided on the top surface of the plug 16; the horizontal section of the limiting rod 17 is located within the movable seat. The top surface of 10 has its vertical section slidably connected in the limiting hole 112. The bottom of the limiting rod 17 is connected to the plug-in 16, and a spring 18 is fitted on the vertical section of the limiting rod 17 (the spring 18 is press-fitted between the plug-in 16 and the limiting hole 112). A spherical end 14 is provided at the right end of the connecting rod 12, and a groove 15 is provided on the end 14. The groove 15 is adapted to the plug-in 16. In order to facilitate the release of the limit, a rounded corner is provided at the edge of the groove 15, and a rounded corner is also provided at the bottom edge of the plug-in 16. With the rounded corner design, when it is necessary to release the limit, it is only necessary to rotate the connecting rod 12 by 90 degrees.

[0024] To facilitate adjustment of the extension length of the connecting rod 12, two sets of adjusting nuts 13 are provided on the connecting rod 12, and the adjusting nuts 13 are located on the left and right sides of the movable seat 10.

[0025] As one embodiment of this invention, in order to facilitate knowing the orientation of the groove 15, a calibration block 121 is provided on the outer wall of the connecting rod 12.

[0026] The working principle of this utility model is as follows: By activating the telescopic push cylinder 5 on the reinforcing beam 4, the telescopic end of the telescopic push cylinder 5 pushes the end block 6 to move to the right. During this process, the end block 6 drives the movable mold 9 to slide on the base plate 1 and the track 2 through the connecting rod 7, and the fixing part 3 slides on the track 2. Then, the fixed mold 8 and the movable mold 9 are connected. During this process, the end 14 of the connecting rod 12 is inserted into the fixing hole 111 of the fixing seat 11. Through the shape of the end 14, the plug 16 is pushed upward, and the plug 16 squeezes the spring 18 in the limiting hole 112 during the lifting process, so that the limiting rod 17 is pushed upward. Then, under the action of the spring 18, the plug 16 is inserted into the groove 15 to achieve the limit. Then, concrete is injected.

[0027] After the concrete injection is completed, the connecting rod 12 is rotated 90 degrees in the movable hole 101 of the movable seat 10, so that the end of the plug 16 is engaged with the chamfer on the groove 15, and the plug 16 slides out of the groove 15. After the limit is released, the moving component is operated in the opposite direction to release the limit. Then, the orientation of the groove 15 is determined by observing the calibration block 121.
