Abstract
Description
Technical Field
[0001] The utility model relates to the field of waterproof board connection, and particularly relates to a leak-proof connection structure for a water separation board. Background Art
[0002] Figure 1 A conventional water separation board connection structure is shown. A waterproof board 10 that forms a water storage inner bladder is laid in the inner wall 40 of a pool. The edges of adjacent sheet-like waterproof boards 10 are overlapped and hot-melted to achieve fixation between the two. This connection scheme has a simple structure and is easy to design. However, there are many limiting factors during construction. The main connection and fixation method of existing food-grade plastic boards is to heat the material to melt it, apply pressure and maintain the pressure, and the material can be firmly integrated after cooling to achieve the purpose of fusion welding and fixation. In order to meet the standard of the transverse shear force after the board material is melted, the width of the welding surface usually needs to reach about 100 mm. Since it is not conducive to using a modular electrofusion welder to weld plate materials, and using a hot melt gun for construction on a large area results in a low degree of construction standardization, difficult quality control, and high technical requirements for operators. Summary of the Utility Model
[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of the utility model is to provide a leak-proof connection structure for a water separation board, change the original connection structure, and reduce the construction difficulty.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0005] A leak-proof connection structure for a water separation board, a lapping area for overlapping the two water separation boards is arranged on one side where two water separation boards are adjacent, an adhesive layer is arranged in the lapping area, the adhesive layer fixes the two water separation boards, and a welding seal edge for blocking liquid from flowing into contact with the adhesive layer is also arranged on the side of the adhesive layer.
[0006] In a preferred embodiment of the utility model, the maximum distance between the welding seal edge and the adhesive layer is 10 mm, and the minimum width of the adhesive layer is 100 mm.
[0007] In a preferred embodiment of the utility model, the welding seal edge includes a pair of first welding seal edges, and the first welding seal edges are arranged opposite to each other on two non-overlapping sides of the adhesive layer.
[0008] In a preferred embodiment of the utility model, the welding seal edge further includes at least a pair of second welding seal edges, the second welding seal edges are also located on two sides of the adhesive layer opposite to each other, and the ends of the second welding seal edges are joined to the first welding seal edges.
[0009] In a preferred embodiment of the present utility model, the material of the bonding layer is one of a one-component silicone structural adhesive or a two-component composite silicone.
[0010] The beneficial effects of the present utility model are as follows:
[0011] A leak-proof connection structure for a water barrier plate provided by the present utility model changes the original large-area hot-melt connection method to a bonding method, and at the same time arranges a welded edge sealing on the side of the bonding layer to prevent the bonding layer from aging when soaked in water for a long time, reducing the construction difficulty and improving the efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present utility model or the prior art, the following will briefly introduce the drawings required for use in the description of the embodiments or the prior art.
[0013] Figure 1 is a schematic diagram of the existing connection structure.
[0014] Figure 2 is a schematic diagram of the connection structure of the present utility model.
[0015] Figure 3 is a schematic diagram of an implementation manner of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. The above description is for the convenience of describing the present utility model and simplifies the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0017] The following will describe exemplary embodiments of the present application with reference to the drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals represent the same or functionally identical elements.
[0018] Figure 2The connection structure of the water barrier plate is shown. Two water barrier plates 10 are overlapped and projected on the adjacent sides to form a lapping area 11. An adhesive layer 20 is arranged in the lapping area 11 to fix the two water barrier plates 10 tightly and firmly together. The adhesive layer 20 is not fully distributed in the lapping area 11, that is, the area of the adhesive layer 20 is smaller than that in the lapping area 11 and gaps can be left around the adhesive layer 20. To ensure the bonding force between the water barrier plates 10, the minimum width of the adhesive layer 20 is 100 mm. The material of the adhesive layer 20 is one of a one-component silicone structural adhesive or a two-component composite silicone.
[0019] Since the adhesive layer 20 is attached between the two water barrier plates 10 by an external coating method, considering the construction conditions and the characteristics of the glue itself, it may fail if it is immersed in water for a long time. Therefore, a pair of first welding seal edges 31 respectively located on both sides of the adhesive layer 20 and opposite to each other form a seal on the side of the adhesive layer 20 to prevent liquid from flowing in and contacting the adhesive layer 20. The external coating construction can be carried out quickly, reducing the difficulty and improving the efficiency.
[0020] Combined with reference Figure 3 , the water barrier plates 10 may not be installed vertically as a whole, but are installed in a small-piece and matrix-like splicing manner. Therefore, a pair of second welding seal edges 32 are added on the upper and lower sides of the adhesive layer 20. The two ends of the second welding seal edges 32 are respectively connected to the above-mentioned pair of first welding seal edges 31, so as to construct a waterproof and sealed area around the adhesive layer 20 by combining the first welding seal edges 31 and the second welding seal edges 32. The maximum distance between the welding seal edge and the adhesive layer 20 is 10 mm.
[0021] In the specification, when it is said that an element is "on", "fixed" to, "connected" to, "joined" to another element, etc., the element can be directly on, fixed to, connected to, joined to or in contact with another element, or there may be an intermediate element. In the specification, a feature is arranged "adjacent" to another feature, which may mean that a feature has a part overlapping with the adjacent feature or a part located above or below the adjacent feature.
[0022] It can be understood that although terms such as "first", "second", etc. can be used here to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Therefore, the first element can be called the second element without departing from the teachings of the concept of this application.
