[0002] In building construction, the post-cast joints are concrete strips left at the corresponding positions of the foundation slab, walls, and beams in order to prevent harmful cracks that may be caused by uneven shrinkage or settlement of reinforced concrete structures. Rubber waterstops are used to seal these deformation joints and construction joints before concrete pouring, thereby playing a role in water stopping and preventing seepage.

[0003] The prior art patent announcement number is CN217581326U, which is a post-casting rubber water stop installation fixture. The above patent includes a lower arm positioning rib and a clamping positioning rib. The clamping positioning rib is composed of a U-shaped positioning rib, an upper arm positioning rib and an upper arm fixing head. A water stop sheet is provided on the upper arm positioning rib. Clamps are welded on both sides of the inner wall of the U-shaped positioning rib. The clamp on one side of the U-shaped positioning rib is screwed with bolts. One end of the bolt is located between the U-shaped positioning ribs on both sides and is connected to a locking plate. The lower arm positioning rib and the clamping positioning rib are The ends are connected to the main reinforcement of the wall panel through a binding structure. The device ensures the waterproof and anti-seepage effect of the post-casting joint, and at the same time recycles and reuses waste steel bars, which is economical and reasonable; but there are still the following shortcomings in actual use: From a practical point of view, the device can only fix the waterstop, but during pouring, the rubber waterstop will not be straightened, and it is easy to be affected by the pressure and extrusion during concrete pouring, causing the waterstop to shift or misplace in the structural gap, thereby destroying the sealing performance of the waterstop and reducing its waterproof effect.

[0004] Therefore, a post-cast strip rubber waterstop installation and fixing fixture is needed to solve the problem that the fixing device in the prior art cannot straighten the rubber waterstop and affect its waterproof effect. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a post-casting belt rubber waterstop installation and fixing fixture, including two external fixing blocks 1, the tops of the two external fixing blocks 1 are fixedly connected to two support plates 2, a two-way threaded rod 3 is rotatably connected between every two corresponding support plates 2, the outer walls of the two two-way threaded rods 3 are rotatably connected to two ball nut seats 4, a plurality of ball nut seats 4 are each provided with a clamping mechanism 5 on the top, the rear ends of the two two-way threaded rods 3 are each fixedly connected to a crank 6, and a waterstop body 7 is installed between the plurality of clamping mechanisms 5.

[0023] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that a limiting groove corresponding to the ball nut seat 4 is opened on the top of the external fixing block 1, which plays a role of limiting and guiding the ball nut seat 4, so that the ball nut seat 4 drives the clamping mechanism 5 to move more stably.

[0024] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth explaining in detail that the rear end of the bidirectional threaded rod 3 passes through the support plate 2 and is fixedly connected to the crank 6, ensuring that the bidirectional threaded rod 3 can drive the bidirectional threaded rod 3 to rotate stably, thereby providing driving force for the displacement of the ball nut seat 4.

[0025] According to the above working process, it can be known that: by setting the ball nut seat 4 and the clamping mechanism 5 to cooperate, after the clamping mechanism 5 clamps and fixes the waterstop body 7, the ball nut seat 4 drives multiple clamping mechanisms 5 to move outward to straighten the waterstop body 7. The straightened waterstop body 7 can tightly fill the structural gap to ensure that there is no gap in the gap, thereby effectively preventing the penetration of moisture or other liquids. At the same time, the straightened waterstop body 7 can more effectively prevent the concrete from exerting pressure on it and shifting or destroying it during pouring, which helps to reduce damage to the waterstop body 7 and material waste.

[0026] Further as Figure 4 As shown, it is worth specifically explaining that the clamping mechanism 5 includes a concave frame 501 fixedly connected to the top of the ball nut seat 4, the outer side of the concave frame 501 is rotatably connected to the second threaded rod 502, the inner side of the second threaded rod 502 is rotatably connected to the trapezoidal push block 503, the outer side of the second threaded rod 502 is fixedly connected to a rotating plate 504, the outer side of the trapezoidal push block 503 is fixedly connected to two limiting columns 505, the lower surface of the top and the upper surface of the bottom of the concave frame 501 are fixedly connected to two connecting ears 506, and each two corresponding connecting ears 506 are fixedly connected to the second threaded rod 502. 06 are rotatably connected with a rotating shaft 507, the outer walls of the two rotating shafts 507 are fixedly connected with pipe sleeves 508, the outer sides of the two pipe sleeves 508 are fixedly connected with first connecting rods 509, the ends of the two first connecting rods 509 are installed with guide wheels 510, the inner sides of the two pipe sleeves 508 are fixedly connected with second connecting rods 511, and the ends of the two second connecting rods 511 are installed with clamping plates 512. By setting the clamping mechanism 5, the two clamping plates 512 are moved inward to clamp and fix the waterstop belt body 7, which is simple to operate and has a firm clamping effect.

[0027] Further as Figure 4 As shown, it is worth explaining in detail that a threaded hole corresponding to the second threaded rod 502 and a guide hole corresponding to the limiting column 505 are provided on the surface of the concave frame 501. The threaded hole cooperates with the second threaded rod 502 to ensure that the second threaded rod 502 can drive the trapezoidal push block 503 to move while rotating. The guide hole cooperates with the limiting column 505 to limit the displacement of the trapezoidal push block 503, so that the movement of the trapezoidal push block 503 is more stable.

[0028] Further as Figure 4As shown, it is worth explaining in detail that the outer wall of the guide wheel 510 rolls in contact with the outer wall of the trapezoidal push block 503 to ensure that the movement of the trapezoidal push block 503 can drive the two guide wheels 510 to move outward at the same time, thereby providing power for the movement of the splint 512.

[0029] Further as Figure 4 As shown, it is worth explaining in detail that a plurality of evenly distributed anti-slip teeth are fixedly connected to the inner wall of the splint 512, so as to increase the friction between the splint 512 and the waterstop body 7 and prevent the waterstop body 7 from sliding during installation and fixation.

[0030] This solution has the following working process: in actual use, the waterstop body 7 is placed between the two clamps 512, and the second threaded rod 502 is rotated to drive the trapezoidal push block 503 to move. While the trapezoidal push block 503 moves, it drives the two guide wheels 510 to roll outward. Under the action of the rotating shaft 507, the two clamps 512 move inward to clamp and fix the waterstop body 7, and then the crank 6 is rotated to drive the bidirectional threaded rod 3 to rotate. While the bidirectional threaded rod 3 rotates, it drives the ball nut seat 4 to move, so that the ball nut seat 4 drives multiple clamping mechanisms 5 to move outward to straighten the waterstop body 7.

[0031] In summary: by setting the ball nut seat 4 and the clamping mechanism 5 to cooperate, after the clamping mechanism 5 clamps and fixes the waterstop body 7, the ball nut seat 4 drives the multiple clamping mechanisms 5 to move outward to straighten the waterstop body 7. The straightened waterstop body 7 can tightly fill the structural gap to ensure that there is no gap in the gap, thereby effectively preventing the penetration of moisture or other liquids. At the same time, the straightened waterstop body 7 can more effectively prevent the concrete from exerting pressure on it and shifting or destroying it during pouring, which helps to reduce damage to the waterstop body 7 and material waste; by setting the clamping mechanism 5, the two clamping plates 512 move inward to clamp and fix the waterstop body 7, which is simple to operate and firmly clamped.
