Description

Technical Field

[0001] The utility model relates to the field of water-stop screw eye plugging construction, in particular to a tool for assisting water-stop screw eye mortar cake plugging operations. Background Art

[0002] With the continuous development of modern construction technology, the requirements for waterproof performance of buildings are increasing day by day, especially in underground projects, pools, bridges and other structures that are in close contact with the water environment, waterproof engineering is even more important. In these structures, water stop screws are key components for template reinforcement. After the concrete is poured, they need to be removed, leaving water stop screw holes. If these holes are not handled properly, they can easily become channels for water leakage, seriously affecting the overall waterproof effect and durability of the building.

[0003] The conventional method of sealing the eyes of water-stop screws mainly relies on filling and compacting the mixed mortar, and keeping it flat with the surrounding structural surface as much as possible. Although this method can seal the holes to a certain extent, its waterproof effect is often not very good when facing complex environments such as high water pressure and long-term flooding, especially in areas with abundant adjacent water, it is even more difficult to ensure long-term waterproof reliability. In order to enhance the waterproof performance of the eyes of water-stop screws, the industry has proposed an improvement plan, that is, to add a certain amount of impermeable crystalline material, Kress, into the mortar, and its dosage is usually 2% (by weight) of the cement dosage in the mortar. By applying a mortar ash cake containing Kress to the screw eye, a round cake-shaped structure with a diameter of 50mm and a thickness of 15mm is formed, and the impermeability characteristics of the Kress material are utilized to significantly improve the waterproof ability of the sealing part. However, there are obvious disadvantages in the implementation process of this method, that is, the ash cake application operation is highly dependent on manual operation, which is not only time-consuming and labor-intensive, but also difficult to ensure the uniformity and consistency of each ash cake, which in turn affects the overall waterproof effect. At the same time, the construction efficiency is low, which increases the project cost. Summary of the invention

[0004] In view of the problems existing in the prior art, the utility model provides a tool to assist in the mortar cake sealing operation of the water-stop screw eye, which aims to shorten the mortar cake production time, improve construction efficiency, improve the mortar cake quality, reduce project costs, and standardize the sealing operation.

[0005] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:

[0006] A tool to assist in sealing mortar cakes in water-stop screw eyes, comprising a scissor fork member formed by hingedly connecting a first rod and a second rod, wherein the first end of the first rod is fixedly connected to a first connecting rod, the first end of the second rod is fixedly connected to a second connecting rod, an end of the first connecting rod away from the first rod is connected to a first semi-circular arc retaining ring, an end of the second connecting rod away from the second rod is connected to a second semi-circular arc retaining ring, the first semi-circular arc retaining ring and the second semi-circular arc retaining ring can be connected to form a circular retaining ring for accommodating mortar.

[0007] Furthermore, the included angle between the first connecting rod and the first rod is 140° to 150°; the included angle between the second connecting rod and the second rod is 140° to 150°.

[0008] Furthermore, the second end of the first rod and the second end of the second rod are both provided with an elliptical handle.

[0009] Furthermore, the elliptical handle is covered with a rubber sleeve.

[0010] Furthermore, the first rod member and the second rod member are connected by a hinge bolt near the middle.

[0011] Further, the bottom of the first semi-circular arc retaining ring is flush with the bottom of the first connecting rod, and the bottom of the second semi-circular arc retaining ring is flush with the bottom of the second connecting rod.

[0012] Furthermore, the size of the circular retaining ring matches the size of the mortar cake to be produced.

[0013] Furthermore, the first connecting rod and the first semi-circular arc retaining ring are fixedly connected by welding, and the second connecting rod and the second semi-circular arc retaining ring are fixedly connected by welding.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects:

[0015] The utility model provides a tool for assisting the sealing operation of the mortar cake of the water-stop screw eye. When in use, first, the first rod and the second rod of the scissor fork are manipulated so that the first semi-circular arc retaining ring and the second semi-circular arc retaining ring are butted and closed to form a circular retaining ring, and the circular retaining ring is placed at the water-stop screw eye; next, the pre-mixed mortar is evenly applied to the circular retaining ring, and the restraining effect of the circular retaining ring is utilized to ensure that the mortar can fill the entire screw eye and form the required mortar cake shape; finally, after the mortar is initially set, the first rod and the second rod of the scissor fork are manipulated so that the first semi-circular arc retaining ring and the second semi-circular arc retaining ring are separated from the mortar cake, and the mortar cake sealing operation of a water-stop screw eye can be completed.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Combination Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a tool for assisting the sealing operation of the mortar cake of the water-stop screw eye, aiming to solve the problem of time-consuming, labor-intensive and inefficient application of the mortar cake in the existing water-stop screw eye sealing operation. The tool for the sealing operation includes a scissor fork member formed by hinged connection of a first rod 1 and a second rod 2. The design of this scissor fork structure enables the tool to be opened and closed as needed when in use. A first connecting rod 3 is fixedly connected to the first end of the first rod 1, and a second connecting rod 4 is fixedly connected to the first end of the second rod 2. The first connecting rod 3 and the second connecting rod 4 serve as supporting and connecting parts, respectively, for installing subsequent semi-circular retaining rings. A first semi-circular retaining ring 5 is connected to the end of the first connecting rod 3 away from the first rod 1, and a second semi-circular retaining ring 6 is connected to the end of the second connecting rod 4 away from the second rod 2. The first semi-circular retaining ring 5 and the second semi-circular retaining ring 6 can be connected to form a circular retaining ring for accommodating mortar. The first semi-circular retaining ring 5 and the second semi-circular retaining ring 6 are both designed to be semicircular so that the two can be connected to form a complete circular retaining ring. The diameter and thickness of the semicircular arc retaining ring are determined according to actual needs to adapt to the size of the mortar cake of the water-stop screw eye.

[0023] Specifically, when in use, first, manipulate the first rod 1 and the second rod 2 of the scissor fork member so that the first semi-circular arc retaining ring 5 and the second semi-circular arc retaining ring 6 are docked and closed to form a circular retaining ring, and the circular retaining ring is placed at the water-stop screw eye; next, evenly apply the pre-mixed mortar (containing an appropriate amount of impermeable crystalline material such as KRIS) in the circular retaining ring, and use the restraining effect of the circular retaining ring to ensure that the mortar can fill the entire screw eye and form the required ash cake shape; finally, after the mortar is initially set, manipulate the first rod 1 and the second rod 2 of the scissor fork member so that the first semi-circular arc retaining ring 5 and the second semi-circular arc retaining ring 6 are separated from the ash cake, and the mortar ash cake sealing operation of a water-stop screw eye can be completed. Since this tool adopts the design of scissor forks and semi-circular arc retaining rings, the sealing operation becomes simpler and faster, which not only improves the construction efficiency, but also ensures the uniformity and consistency of the ash cake, which is conducive to improving the overall waterproof effect. In addition, the tool has a simple structure, is easy to operate, easy to clean and maintain, and is suitable for water-stop screw eye sealing operations in various construction projects.

[0024] In one possible implementation, combining Figure 1 and Figure 2 As shown, the angle between the first connecting rod 3 and the first rod 1 is set to be between 140° and 150°, and similarly, the angle between the second connecting rod 4 and the second rod 2 is also set to be between 140° and 150°. This design takes into account the flexibility and stability of the tool in actual use. When the angle is within this range, it conforms to the working habits, the tool is more operable, and when applying mortar, it is also conducive to the two semi-circular retaining rings to fit tightly together to form a complete circular retaining ring, avoiding the problem of mortar overflow or uneven filling.

[0025] In one possible implementation, Figure 1 As shown, in order to improve the user's comfort and operational stability during use, an elliptical handle 7 is provided at the second end of the first rod 1 and the second end of the second rod 2.

[0026] Specifically, the design of the elliptical handle 7 fully considers the principles of ergonomics and aims to provide users with the best gripping experience. This handle not only conforms to the natural curvature of the palm and realizes the one-handed operation function, but also can provide sufficient support and anti-slip effect when the user applies force, reduce hand fatigue, and improve work efficiency. In actual operation, the user can control the opening and closing angle of the scissor fork by holding the two elliptical handles 7, so that the first semi-circular arc retaining ring 5 and the second semi-circular arc retaining ring 6 can be accurately aligned and cover the water stop screw eye to be blocked. By adding the elliptical handle 7, not only the ease of use and comfort of the tool are improved, but also its adaptability and reliability in actual construction scenarios are further enhanced, making the tool more handy in assisting the water stop screw eye mortar cake blocking operation, providing users with a more efficient and convenient solution.

[0027] Preferably, in order to enhance the comfort and anti-slip performance of holding, a rubber sleeve is added to the quasi-elliptical handle 7. The rubber sleeve has good elasticity and wear resistance, can fit the palm of the user closely, and provides a soft and stable grip.

[0028] Exemplarily, the surface of the rubber sleeve may also be designed with anti-slip textures or particles to further increase the friction when holding and prevent the tool from slipping due to sweaty or slippery hands during use.

[0029] In one possible implementation, Figure 1 and Figure 2 As shown, the first rod 1 and the second rod 2 are connected near the middle by a hinge bolt 8 to form a basic frame of the scissors fork. The scissors fork can maintain a stable structural form during the opening and closing process and is not prone to twisting or deformation.

[0030] Preferably, Figure 2 As shown, the bottom of the first semi-circular arc retaining ring 5 is flush with the bottom of the first connecting rod 3 , and the bottom of the second semi-circular arc retaining ring 6 is flush with the bottom of the second connecting rod 4 .

[0031] In other words, the relative position relationship between the semicircular retaining ring and the corresponding connecting rod is taken into consideration to ensure that the tool can more smoothly seal the water stop screw eye during use, fit the water stop screw eye more easily, and is less likely to leak mortar. Specifically, the flat bottom helps to improve the stability of the tool during mortar filling. When the mortar is poured into the circular retaining ring, since the bottom of the retaining ring is flush with the bottom of the connecting rod, the mortar can be better confined inside the retaining ring, reducing the possibility of overflow, and is also conducive to the uniform distribution and compaction of the mortar.

[0032] Preferably, in order to ensure that the mortar cake formed after the sealing operation can fit tightly into the eye of the waterstop screw while ensuring the strength and aesthetics of the cake, the size of the circular retaining ring is designed to match the size of the mortar cake to be produced.

[0033] The first connecting rod 3 is fixedly connected to the first semi-circular arc retaining ring 5 by welding, the second connecting rod 4 is fixedly connected to the second semi-circular arc retaining ring 6 by welding, the first rod 1 is fixedly connected to the first connecting rod 3 by welding, and the second rod 2 is fixedly connected to the second connecting rod 4 by welding. Welding can ensure that a stable overall structure is formed between the connecting rod and the semi-circular arc retaining ring. Fixing the connecting rod and the semi-circular arc retaining ring by welding not only improves the overall strength and stability of the tool, but also helps to simplify the manufacturing process of the tool. During the manufacturing process, the connecting rod and the semi-circular arc retaining ring can be processed and formed separately, and then the two can be firmly connected together by welding. In actual use, there is no need to worry that the connection between the connecting rod and the semi-circular arc retaining ring will loosen or fall off, and the welding connection between them ensures that the tool can still maintain stable performance when dealing with various complex construction environments.

[0034] In one embodiment, the diameter of the ring 1, the first semi-circular arc retaining ring 5 and the second semi-circular arc retaining ring 6 is 50 mm, the height is 15 mm, and the thickness is 2 mm. The length of the first connecting rod 3 and the second connecting rod 4 is 100 mm, the width is 4 mm, and the height is 8 mm. The length of the first rod 1 and the second rod 2 is 210 mm. The angle between the first connecting rod 3 and the first rod 1 is 145°, and the angle between the second connecting rod 4 and the second rod 2 is 145°. The first rod 1, the second rod 2, the first connecting rod 3, the second connecting rod 4, the first semi-circular arc retaining ring 5 and the second semi-circular arc retaining ring 6 are all made of Q235 steel.

[0035] In this embodiment, the construction method of the tool for assisting the sealing operation of the mortar cake of the water-stop screw eye includes the following steps:

[0036] Step 1: After the concrete strength reaches the design strength, remove the rubber plug of the water stop screw;

[0037] Step 2: Chisel, clean and moisten the area around the water stop screw eye;

[0038] Step 3: Mix anti-seepage crystalline mortar - "Mortar + KRES (the amount of KRES is 2% of the amount of cement in the mortar {weight ratio})";

[0039] Step 4: Use the tool for assisting the sealing operation of the mortar cake of the water-stop screw eye to manipulate the first rod 1 and the second rod 2 of the scissor fork, so that the first semi-circular arc retaining ring 5 and the second semi-circular arc retaining ring 6 are butted and closed to form a circular retaining ring, and the circular retaining ring is placed at the water-stop screw eye, and then use anti-seepage crystal mortar to apply a round cake with a diameter of 50 mm and a thickness of 15 mm, compact it, and smooth it;

[0040] Step 5: After the smeared ash cake is initially fixed, the first rod 1 and the second rod 2 of the scissor fork are manipulated to separate the first semi-circular arc retaining ring 5 and the second semi-circular arc retaining ring 6 from the ash cake, and the ash cake is completed;

[0041] Step 6: Curing for 7 days to ensure the strength of the ash cake and to ensure that the ash cake does not shrink and crack; at the same time, KRIS will react chemically with water and unhydrated cement particles to generate insoluble needle-shaped crystals, which will fill the fine pores and tiny cracks in the mortar and block the infiltration channels of moisture and water-borne pollutants.

[0042] The mortar ash cake produced in this embodiment is formed in one step and is not easy to fall off, which ensures the quality of the ash cake, greatly improves the construction efficiency, and saves the construction period. The construction method is simple to operate, has obvious economic benefits, does not require special equipment and processes, has low construction costs, has good promotion prospects, and ensures the appearance shape and size consistency of the ash cake.

[0043] The tool is simple to make, low in cost, small in size, easy to operate, saves time and effort, improves quality while increasing efficiency.
