Rubber waterstop fixing device

Abstract

The utility model provides a rubber waterstop fixing device which effectively solves the problems that in the prior art, when a rubber waterstop is fixed, due to the fact that the number of stress points is small, and the stress area is small, the rubber waterstop is prone to deformation, and the construction requirements of different types of construction joints can be met. According to the technical scheme, the device comprises a horizontal double-end lead screw, and nuts are screwed at the two ends of the double-end lead screw; two rotating rods are arranged below the double-end lead screw, the middles of the two rotating rods are hinged together to form an X-shaped structure, U-shaped plates with inward openings are fixed to the ends of the rotating rods, connecting rods are hinged to the upper ends of the U-shaped plates, and the other ends of the connecting rods are hinged to nuts. When the double-end lead screw rotates to drive the two nuts to move at the same time, the nuts drive the rotating rods to rotate through the connecting rods on the nuts.

Technical Field

[0001] The utility model relates to the technical field of rubber water stop belt installation and shaping fixtures, in particular to a rubber water stop belt fixing device. Background Art

[0002] The rubber waterstop is generally set as a mid-embedded type, located in the middle of the construction joint or deformation joint surface of the front and rear concrete casting blocks of the structure. A rubber waterstop fixing device is disclosed in the Chinese patent document CN214614668U, which can accurately position the rubber waterstop without damaging the rubber waterstop. The binding points can be evenly set on the left and right sides of the rubber waterstop by adjusting the direction of the fixing device to improve the stability of the fixation. The construction quality of the rubber waterstop can be improved to a certain extent, but in construction, it still faces the following defects: First, the scheme is essentially based on special-shaped steel bars, and the rubber waterstop is fixed in multiple places by bending and binding, but the contact area between the steel bars and the rubber waterstop is limited, and the rubber waterstop is easily deformed under the action of gravity; second, the width of the scheme is fixed during implementation, and it can only adapt to waterstops of a specific width. In construction, the rubber waterstop has more than one specification and is not very adaptable.

[0003] A rubber waterstop fixing device is first provided, which can provide stable support for the rubber waterstop and greatly reduce the probability of deformation of the rubber waterstop, can ensure that the rubber waterstop is in the middle of the construction joint, can be flexibly adjusted to adapt to rubber waterstops of different widths, and has a wide range of applications. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a rubber waterstop fixing device, which effectively solves the problem in the prior art that the rubber waterstop is easy to deform when being fixed due to fewer stress points and small stress area, and can meet the construction requirements of different types of construction joints.

[0005] The technical solution is to include a horizontal double-ended lead screw with nuts screwed on both ends; there are two rotating rods below the double-ended lead screw, the middle parts of the two rotating rods are hinged together to form an X-shaped structure, and the ends of the rotating rods are fixed with U-shaped plates opening inward, the upper ends of the U-shaped plates are hinged with connecting rods, and the other ends of the connecting rods are hinged to the nuts; when the double-ended lead screw rotates to drive the two nuts to move simultaneously, the nuts drive the rotating rods to rotate via the connecting rods thereon.

[0006] Furthermore, a cross bar parallel to the double-ended screw is disposed above the cross bar, and a plurality of vertical connecting plates are disposed at the lower end of the cross bar, and the double-ended screw is rotatably mounted on the connecting plates.

[0007] Furthermore, the connecting rod is inclined.

[0008] The utility model has an ingenious structure, can provide stable support for the rubber waterstop, and greatly reduce the probability of deformation of the rubber waterstop, can ensure that the rubber waterstop is in the middle of the construction joint, can be flexibly adjusted to adapt to rubber waterstops of different widths, and has a wide range of applications.

[0012] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 3 It is given that the utility model includes a horizontal double-headed screw 1, both ends of which are screwed with nuts 2; there are two rotating rods 3 below the double-headed screw 1, the middle parts of the two rotating rods 3 are hinged together to form an X-shaped structure, and the ends of the rotating rods 3 are fixed with U-shaped plates 4 with inward openings, and the upper ends of the U-shaped plates 4 are hinged with connecting rods 5, and the other ends of the connecting rods 5 are hinged together with the nuts 2; when the double-headed screw 1 rotates to drive the two nuts 2 to move at the same time, the nuts 2 drive the rotating rods 3 to rotate via the connecting rods 5 thereon.

[0014] In order to be able to adjust the device after installation, there is a cross bar 6 parallel to the double-headed screw 1 above the cross bar 6, and a plurality of vertical connecting plates 7 are provided at the lower end of the cross bar 6. The double-headed screw 1 is rotatably installed on the connecting plate 7. During installation, the cross bar 6 can be pre-installed on the concrete construction joint, and then the double-headed screw 1 can be screwed so that the distance between the U-shaped plates 4 on the left and right sides is adapted to the rubber waterstop.

[0015] In order to prevent interference between components, the connecting rod 5 is inclined.

[0016] It is worth noting that a bearing is installed between the connecting plate 7 and the double-ended screw 1; the middle parts of the two rotating rods 3 are hinged together through a vertical rotating pin, and a bearing is installed between the rotating pin and the rotating rod 3.

[0017] When in use, first tie the two ends of the cross bar 6 in the device to the concrete structure steel bars together, and install multiple devices in the construction joint in this way, and ensure that the device is in the middle of the construction joint, and then pass the rubber waterstop through it in turn to complete the laying and fixing of the rubber waterstop.

[0018] After laying is completed, in order to further prevent the rubber waterstop from being displaced or offset, the tightening screws can be screwed on the side plates of the U-shaped plate 4. The tightening screws press the rubber waterstop to firmly fix it in the U-shaped plate 4. After fixation, the rubber waterstop can be adjusted slightly within a small range by screwing the double-headed screw 1.

[0019] The multiple U-shaped plates 4 in this solution can provide multiple and stable supports for the rubber waterstop, increase the contact area, effectively prevent the rubber waterstop from deforming, and ensure that the rubber waterstop can be stably located in the middle of the construction joint.
