Description

Technical Field

[0001] The utility model relates to the field of concrete structure engineering, in particular to a novel metal water stop strip structure. Background Art

[0002] There are four types of connection methods for metal waterstops in the prior art: right-angle connection, claw connection, bolt connection, and welding connection. The above types of waterstop connection methods mainly have the following advantages and disadvantages:

[0003] (1) The right-angle connection is one of the common connection methods for metal waterstops. The connection method is to cut two pieces of waterstops into 90 degrees respectively and then connect them through a bite hinge. This connection method is simple and easy to implement, but its main problem is that the connection is not tight enough and it is easy to leak.

[0004] (2) The hook-claw connection is a connection method in which the overlapping ends of two waterstops are locked together with hooks. When connecting, the hooks need to be staggered a certain distance, then pushed in along the overlapping direction of the waterstop, and finally hammered tightly with a rubber mallet. This connection method is tight and reliable, but it requires more care during connection. If the connection is improper, damage may occur.

[0005] (3) Bolt connection is a common way to connect metal waterstops. Put two waterstops together first, and then use bolts on the outside to fix the two waterstops together. This connection method has good waterproof effect and stable connection, but it requires setting fixed points on the building structure in advance and using tools to connect the bolts.

[0006] (4) Welding connection is to connect two pieces of waterstop by electric welding. This connection method has the best waterproof effect and a more secure connection, but it requires professionals to perform the welding operation, and care must be taken not to damage the surface coating of the waterstop during the connection process. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a new metal water stop structure which has a simple structure, is easy to operate and has low technical difficulty requirements.

[0008] The technical solution adopted by the utility model to solve its technical problems is: the new metal waterstop structure includes an outer metal waterstop body, a rubber pad and an inner metal waterstop body; the inner metal waterstop body and the outer metal waterstop body respectively include a toothed overlapping portion, the rubber pad is located in the area of ​​the two toothed overlapping portions, and the inner metal waterstop body and the outer metal waterstop body are buckled through the toothed overlapping portion.

[0009] Furthermore, epoxy resin glue is coated between the tooth-shaped overlapping portion and the glue pad.

[0010] Furthermore, the surface of the tooth-shaped overlapping portion has a rough surface layer.

[0011] Furthermore, the tooth-shaped overlapping portion includes a plurality of groove portions, platform portions and ridge portions that are alternately arranged.

[0012] Furthermore, the tooth-shaped overlapping portion includes a platform portion, a groove portion, a platform portion, a ridge portion, a platform portion and a groove portion in sequence.

[0013] Furthermore, the rubber pad is a water-swellable rubber pad.

[0014] Furthermore, the tooth-shaped overlapping portion is formed by pressing.

[0015] This new metal waterstop structure uses the concave and convex shapes of the metal material's toothed overlap to achieve interlocking, and uses rubber pads to strengthen the fitting surface. It is simple to operate on site, has low technical requirements for installers, and its quality is easily guaranteed. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0017] Figure 1 It is a structural schematic diagram of the new metal waterstop structure of the embodiment of the utility model.

[0018] Description of reference numerals:

[0019] 1. External metal waterstop body; 2. Water-expandable rubber pad; 3. Internal metal waterstop body; 4. Tooth-shaped overlapping portion; 41. Platform portion; 42. Groove portion; 43. Protruding ridge portion. DETAILED DESCRIPTION

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present utility model, the specific implementation methods of the present utility model are now described in detail with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the novel metal waterstop structure comprises an outer metal waterstop body 1, a rubber pad and an inner metal waterstop body 3; the inner metal waterstop body 3 and the outer metal waterstop body 1 respectively comprise a toothed overlap portion 4, the rubber pad is located in the region of the two toothed overlap portions 4, and the inner metal waterstop body 3 and the outer metal waterstop body 1 are buckled together through the toothed overlap portion 4. Preferably, the rubber pad is a water-swellable rubber pad 2.

[0022] Epoxy resin glue is also coated between the tooth-shaped overlap portion 4 and the glue pad. In order to further improve the stability and firmness of the connection, the surface of the tooth-shaped overlap portion 4 has a rough surface layer.

[0023] The tooth-shaped overlap portion 4 includes a plurality of groove portions 42, a platform portion 41 and a ridge portion 43 arranged alternately. In this embodiment, the tooth-shaped overlap portion 4 includes a platform portion 41, a groove portion 42, a platform portion 41, a ridge portion 43, a platform portion 41 and a groove portion 42 in sequence. Preferably, the tooth-shaped overlap portion 4 is formed by pressing, that is, a special tool is used to press the overlapping part of the waterstop belt on site or at the manufacturer to form a plurality of concave-convex grooves and the tooth-shaped overlap portion 4, and then epoxy resin glue is applied within the overlapping length range and on the concave-convex grooves, and then a water-swellable waterstop pad of the same size as the overlap surface is attached to one side of the overlap surface, and the metal overlap surface on the other side is buckled into the concave-convex groove of the opposite surface. During construction, the overlap surface and the rubber surface should be flat, clean, dry, and polished to give it a certain degree of roughness.

[0024] This utility model is based on the East Line Project of the South-to-North Water Diversion Project. There are many valve wells, caissons and pools in this project. There will inevitably be construction joints in the horizontal direction during construction, and the installation of metal waterstops in the construction joints is the key control point in construction. The metal waterstop is installed without welding, which speeds up the installation of the metal waterstop during the construction process, ensures the construction quality, reduces the construction cost, and has certain innovation and economic value.

[0025] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0026] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
