Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a rubber water stop belt fixing device. Background Art

[0002] Rubber waterstops are widely used in waterproof structures of expansion joints in water conservancy, subway, construction and other projects due to their high elastic deformation ability. However, due to their soft material and special shape, there are problems such as difficulty in fixing, bending and displacement during installation, which affect their actual function and installation quality and may lead to rework.

[0003] At present, there are relatively many types of fixing devices for rubber waterstops, and their performance varies. Fixing devices with simpler structures have poor fixing effects and are prone to loosening and displacement. Some rubber waterstop fixing devices with better fixing effects have complicated fixing steps, relatively high costs, and relatively poor practicality.

[0004] The utility model patent with publication number CN221031532U discloses a rubber waterstop fixing device, which includes a clamping assembly and a side fixing assembly, etc. The upper and lower clamping plates in the clamping assembly cooperate and are connected with U-shaped fasteners so that the rubber waterstop is fully tightened; the side fixing assembly can be conveniently connected to the steel bars by adjusting the position of the sliding plate on the first connecting plate according to the distance between the steel bars.

[0005] The above-disclosed solution has a good fixing effect and ensures the installation quality, but correspondingly, the manufacturing cost of this solution is relatively higher. In addition, the fixing device provided by this solution is difficult to remove after the concrete is poured. In one construction process, more fixing devices are needed and consumed, which increases the construction cost. Summary of the invention

[0006] The purpose of the present invention is to provide a rubber water stop fixing device in order to solve the above-mentioned problem.

[0007] The present invention achieves the above-mentioned purpose through the following technical solutions: A rubber water stop fixing device, comprising: A U-shaped fastener is used to fix the rubber water stop on the mold plate. The U-shaped fastener is a U-shaped structure. The gap between the two side edges of the U-shaped fastener is used to accommodate the rubber water stop and the mold plate. The U-shaped fastener is provided with a fastening hole for installing a bolt, so that when the bolt is tightened, the two side edges of the U-shaped fastener are close to each other, and the gap between the two side edges of the U-shaped fastener is reduced to fix the rubber water stop; A collar is sleeved on a U-shaped fastener, and is used to squeeze the U-shaped fastener, reduce the gap between the two side edges of the U-shaped fastener, so as to further reinforce the U-shaped fastener and prevent the rubber waterstop from shifting; the collar is a C-shaped structure, and the collar is integrally formed with two connecting plates, and both connecting plates are provided with reinforcement holes for bolts to pass through.

[0008] As a further improvement, a limiting groove for limiting the position of the bolt is also provided in the fastening hole to facilitate tightening the bolt.

[0009] As a further improvement, the U-shaped fastener is a metal U-shaped fastener, and the ring is a metal ring.

[0010] As a further improvement, the U-shaped fastener is made of steel bars or steel plates, and the collar is made of steel plates or steel sheets.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention reduces labor costs and raw material costs. Compared with the prior art, when fixing the rubber waterstop, the present invention is clamped on the rubber waterstop and the mold plate, so that the rubber waterstop and the mold plate are clamped between the U-shaped fasteners, and the initial fixation of the rubber waterstop can be completed. Thereafter, the bolts in the fastening holes and the bolts in the reinforcement holes are tightened in turn to complete the fixation of the rubber waterstop. The installation is convenient, the installation efficiency is improved, and the labor cost is reduced.

[0012] The materials required for making the present invention can utilize steel bars, steel plate scraps, etc. used in daily life, which greatly reduces the raw material cost of the fixing device and realizes the recycling of waste products, which is beneficial to the environment.

[0013] 2. After use, the present invention can be taken out and reused. When taking it out, it only needs to loosen the bolts and pull out the U-shaped fastener from the top, which is easy to operate.

[0014] 3. In addition to fixing the rubber waterstop, the present invention can also be used for the construction of other concrete embedded parts. It has wide applicability and significant economic and social benefits and is worthy of promotion. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0024] The present invention will be further described below in conjunction with the accompanying drawings: Example 1

[0025] like Figure 1-Figure 4As shown, the rubber water stop fixing device includes a U-shaped fastener 1 and a ring 2 installed on the U-shaped fastener 1.

[0026] The U-shaped fastener 1 is used to fix the rubber waterstop on the mold plate. The U-shaped fastener 1 is a U-shaped structure. The U-shaped structure can not only achieve a good clamping effect, but also is convenient to take and place. In this embodiment, the U-shaped fastener 1 is made by bending long strips of steel plate scraps. Such steel plate scraps are abundant at the construction site and can be used directly or after trimming. The steel has a certain elasticity, and the U-shaped fastener 1 can return to its original shape within a certain deformation range; the gap between the two side edges of the U-shaped fastener 1 is used to accommodate the rubber waterstop and the mold plate; the U-shaped fastener 1 is provided with a fastening hole 3 for installing bolts, so that when the bolts are tightened, the two side edges of the U-shaped fastener 1 are close to each other, and the gap between the two side edges of the U-shaped fastener 1 is reduced to fix the rubber waterstop.

[0027] The bolts used in the present invention are butterfly bolts, which are convenient for manual tightening and loosening.

[0028] In this embodiment, a limiting groove 31 for limiting the position of the bolt is further provided in the fastening hole 3 to facilitate tightening the bolt. The limiting groove 31 has a rotation-stopping effect. The limiting groove 31 has at least one rotation-stopping surface. In this way, when tightening the nut, the bolt is stuck in the limiting groove 31 and cannot rotate. The nut can be tightened quickly, reducing the difficulty of manual operation. In this embodiment, the limiting groove 31 is a hexagonal structure.

[0029] The collar 2 is sleeved on the U-shaped fastener 1, and is used to squeeze the U-shaped fastener 1, narrow the gap between the two sides of the U-shaped fastener 1, so as to further reinforce the U-shaped fastener 1 and prevent the rubber water stop from deflecting; the collar 2 is a C-shaped structure, and the collar 2 is integrally formed with two connecting pieces 21, and both connecting pieces 21 are provided with reinforcement holes 22 for bolts to pass through. In this embodiment, the collar 2 is made of steel sheet.

[0030] Working principle: When in use, first fix the rubber water stop on the mold plate, then clamp the fixing device of the present invention on the rubber water stop and the mold plate, preliminarily fix the rubber water stop, and then tighten the bolts in the fastening hole 3 and the bolts in the reinforcement hole 22 in turn to complete the fixing of the rubber water stop. After the concrete pouring is completed, the bolts can be loosened and the fixing device of the present invention can be taken out. Example 2

[0031] like Figure 5 As shown, in this embodiment, the U-shaped fastener is made by bending a steel bar, which can also play the same fastening role. There are many raw materials that can be used to make the present invention, which can be adjusted according to actual conditions. Example 3

[0032] In this embodiment, the fixing device only includes a U-shaped fastener. The U-shaped fastener alone, in conjunction with the bolt, can also complete the fixation, but the stability is relatively weak. The position of the fastening hole can also be appropriately adjusted to increase the bolt fastening effect.

[0033] The basic principles, main features and advantages of the present invention are shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
