Description

Technical Field

[0001] This utility model relates to the field of waterstop technology, specifically to a steel plate waterstop structure. Background Technology

[0002] Steel plate waterstops, also known as water-stop steel plates, are used in box-type foundations or basements where the concrete for the bottom slab, exterior wall panels, and roof slab is poured separately. When the wall panel concrete is poured next, a construction joint is formed. If this joint is below the groundwater level, water seepage is likely to occur. Therefore, technical treatment of this joint is necessary. There are many methods, among which installing waterstop steel plates is a common approach.

[0003] The effectiveness of fixing the steel plate waterstop directly affects the final waterproofing effect of the concrete, making effective fixing crucial. While various methods exist for fixing steel plate waterstops, most are complex and costly, limiting their widespread adoption. On-site, short reinforcing bars are commonly used to weld the waterstop to the structural reinforcement. However, due to varying welder skill levels and harsh working environments, on-site welding frequently results in damage to the waterstop.

[0004] Furthermore, to further improve water resistance, grouting is sometimes required at construction joints, which necessitates pre-embedding grouting pipes during structural pouring. In existing technologies, steel plate waterstops and grouting pipes are fixed separately, leading to increased work time and additional fixing materials. Utility Model Content

[0005] The purpose of this utility model is to provide a steel plate waterstop structure that addresses the above-mentioned problems, facilitates the installation and fixing of the steel plate waterstop, avoids damage to the steel plate waterstop, and also facilitates the fixing of the grouting pipe.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model provides a steel plate waterstop structure, including a waterstop body and connectors; the waterstop body is provided with a groove for accommodating a grouting pipe, the groove is located on the straight section of the waterstop body and extends along the length direction of the waterstop body; there are multiple connectors, which are respectively fixedly disposed on both sides of the straight section of the waterstop body, and the connectors are provided with welding holes for inserting short steel bars.

[0008] As a preferred embodiment of this utility model, the connectors on each side of the straight section of the waterstop body are evenly distributed along the length direction of the waterstop body.

[0009] As a preferred embodiment of this utility model, the connectors on each side of the straight section of the waterstop body are symmetrically distributed on both sides of the groove.

[0010] As a preferred embodiment of this utility model, the connector includes an end plate and a collar. The end plate is fixedly disposed at one end of the collar, and the other end of the collar is fixedly connected to the straight section of the waterstop body. The welding holes are distributed on the end plate and the outer peripheral wall of the collar.

[0011] As a preferred embodiment of this utility model, the end plate and the collar are an integral structure.

[0012] As a preferred embodiment of this utility model, the welding hole on the end plate is located at its center, and the welding holes on the collar are evenly distributed circumferentially on its outer peripheral wall.

[0013] As a preferred embodiment of this utility model, the groove is located in the middle of the straight section of the waterstop body.

[0014] As a preferred embodiment of this utility model, the groove is U-shaped, and the depth of the groove is equal to its width and slightly larger than the diameter of the grouting pipe.

[0015] As a preferred embodiment of this utility model, the groove is formed by integrally pressing the waterstop body using a pressing machine.

[0016] As a preferred embodiment of this utility model, the opening of the groove faces the side that needs grouting, and the grouting pipe is placed in the groove and prevented from sliding out by a U-shaped clamp.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] This invention utilizes a pre-installed connector with welding holes on the straight section of the waterstop body. On-site, a short steel bar is inserted into the welding hole and welded to the connector, while the other end is welded to the structural steel reinforcement. This effectively secures the steel plate waterstop. Because the short steel bar is not directly welded to the waterstop, it avoids the common on-site problem of burning through or damaging the waterstop due to welding. Furthermore, the groove on the straight section of the waterstop body accommodates the grouting pipe, facilitating pipe fixation and reducing material and time consumption for pipe fixing.

[0037] Please refer to Figures 1 to 6 The present application provides a steel plate waterstop structure, including a waterstop body 1 and connectors 2; the waterstop body 1 is provided with a groove 3 for accommodating a grouting pipe, the groove 3 is located on the straight section of the waterstop body 1, and the groove 3 extends along the length direction of the waterstop body 1; there are multiple connectors 2, which are respectively fixedly disposed on both sides of the straight section of the waterstop body 1, and the connectors 2 are provided with welding holes 21 for inserting short steel bars.

[0038] The waterstop body 1 has a straight section and inclined sections connecting both sides of the straight section, and its structure is similar to that of existing steel plate waterstops. The waterstop body 1 can be formed by pressing 3mm thick steel plate. When installing the waterstop, the opening formed by the two inclined sections usually faces the water-facing side, but this can be adjusted according to the specific application.

[0039] Multiple connectors 2 are provided on both sides of the straight section of the waterstop body 1. These connectors 2 can be pre-welded to the waterstop body 1 at the factory. Factory welding has many advantages over on-site welding, effectively avoiding damage to the steel plate waterstop. Furthermore, since the two sides of existing steel plate waterstops are flat and smooth, they may "adhere" together, making them inconvenient to remove. The connectors 2 provided in this application can avoid the "adhesive" effect between two steel plate waterstops, facilitating the loading and unloading of individual steel plate waterstops.

[0040] This application pre-installs a connector 2 on the straight section of the waterstop body 1, and the connector 2 has a welding hole 21. On the construction site, one end of a short steel bar is inserted into the welding hole 21 and welded to the connector 2, and the other end is welded to the structural steel bar. This can effectively fix the steel plate waterstop. Since the short steel bar is not directly welded to the steel plate waterstop, the common situation of burning through or damaging the steel plate waterstop due to welding on the construction site is avoided.

[0041] In existing technologies, the steel plate waterstop and the grouting pipe are fixed separately, which increases the operation time and the amount of fixing materials required. This application addresses this by providing a groove 3 on the straight section of the waterstop body 1 to accommodate the grouting pipe, which facilitates the fixing of the grouting pipe and reduces the consumption of materials and time for fixing it. Furthermore, if deformation occurs at the construction joint, the groove 3 in this application can accommodate small deformations and ensure that the steel plate waterstop remains undamaged.

[0042] According to some embodiments of this application, the connectors 2 on each side of the straight section of the waterstop body 1 are evenly distributed along the length direction of the waterstop body 1. For example, the longitudinal spacing of the connectors 2 along the length direction of the waterstop can be set to 50cm.

[0043] According to some embodiments of this application, connectors 2 on each side of the straight section of the waterstop body 1 are symmetrically distributed on both sides of the groove 3. For example, along the width direction of the waterstop, the lateral spacing of the connectors 2 can be set to 15cm.

[0044] Because the waterstop body 1 has multiple connectors 2 on each side, the steel plate waterstop can remain stable when placed horizontally without external support. Furthermore, during the installation of the steel plate waterstop, suitable connectors 2 can be selected for fixing the waterstop. For example, based on the distribution of the structural reinforcing bars and the length of the short reinforcing bars, certain connectors 2 can be selected for use, as long as they can secure the steel plate waterstop.

[0045] According to some embodiments of this application, the connector 2 includes an end plate 22 and a collar 23. The end plate 22 is fixedly disposed at one end of the collar 23, and the other end of the collar 23 is fixedly connected to the straight section of the waterstop body 1. The welding holes 21 are distributed on the end plate 22 and the outer peripheral wall of the collar 23.

[0046] The connector 2 described above is cylindrical in shape, consisting of an end plate 22 and a collar 23 forming a bottle cap-like structure. It has a diameter of 30mm and an axial length of 20mm. The connector 2 can be designed as a separate unit, with the end plate 22 and collar 23 welded together to form a single unit. The open end of the connector 2 (i.e., the end without the end plate 22) is prefabricated and welded to the straight side of the waterstop body 1 in the factory.

[0047] According to some embodiments of this application, the end plate 22 and the collar 23 are an integral structure. By designing the end plate 22 and the collar 23 as an integral structure, the processing and manufacturing of the connector 2 is facilitated.

[0048] According to some embodiments of this application, the welding holes 21 on the end plate 22 are located at its center, and the welding holes 21 on the collar 23 are evenly distributed circumferentially on its outer peripheral wall.

[0049] All of the above-mentioned welding holes 21 are through holes with a diameter of 10mm. The number of welding holes 21 on the collar 23 can be 4 or 8, etc., and short steel bars can be inserted into the appropriate welding holes 21 to fix the waterstop as needed.

[0050] In use, short reinforcing bars (with a diameter slightly smaller than the welding hole 21) are used on the construction site. One end of the short reinforcing bar is inserted into the welding hole 21 on the end plate 22, and the short reinforcing bar is welded to the end plate 22. The other end of the short reinforcing bar is welded to the structural reinforcing bar, thus fixing the steel plate waterstop in one direction. Similarly, one end of the short reinforcing bar is inserted into the welding hole 21 on the collar 23, and the short reinforcing bar is welded to the collar 23. The other end of the short reinforcing bar is welded to the structural reinforcing bar, thus fixing the steel plate waterstop in the other direction.

[0051] It should be noted that when fixing the steel plate waterstop, one end of each short steel bar is welded to the connector 2, and not directly welded to the steel plate waterstop. At the same time, the appropriate connector 2 and the appropriate welding hole 21 on the connector 2 can be selected according to the distribution of the structural steel bars.

[0052] According to some embodiments of this application, the groove 3 is located in the middle of the straight section of the waterstop body 1.

[0053] According to some embodiments of this application, the groove 3 is U-shaped, and the depth of the groove 3 is equal to its width and slightly larger than the diameter of the grouting pipe. This design allows the grouting pipe to fit perfectly into the groove 3 without protruding beyond it.

[0054] According to some embodiments of this application, the groove 3 is integrally pressed from the waterstop body 1 using a pressing machine. During manufacturing, it is only necessary to press the groove 3 into the middle of the straight section of the existing steel plate waterstop using equipment. This not only facilitates the production and manufacturing of the steel plate waterstop, but also does not affect the transportation and storage of the steel plate waterstop, allowing it to be stacked vertically.

[0055] Specifically, after the groove 3 is pressed and formed, it forms two straight segments and one arc segment. One end of the two straight segments is connected to the middle of the waterstop, and the arc segment is connected to the other end of the two straight segments. The highest point of the outer wall of the arc segment (the side facing away from the inside of the groove 3) can be flush with or slightly lower than the end of the connector 2.

[0056] According to some embodiments of this application, the opening of the groove 3 faces the side that needs grouting, and the grouting pipe is placed in the groove 3 and prevented from sliding out by the U-shaped clamp 4.

[0057] The U-shaped clamp 4 can be made of thin steel sheet or thin steel wire bent into shape to match the groove 3. After the grouting pipe is placed in the groove 3, multiple U-shaped clamps 4 can be inserted at intervals to block the grouting pipe and prevent it from sliding out of the groove 3. It should be noted that the direction of the groove 3 can be determined according to the specific application, showing which side of the waterstop it is recessed towards.

[0058] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
