Description

Technical Field

[0001] The utility model relates to the field of transformation of water storage structures, and particularly to a fixing structure for a water tank inner liner water separation plate. Background Art

[0002] The Chinese invention patent authorization announcement number CN103590446B discloses a method for transforming a roof water tank and the obtained roof sanitary water tank. A PE soft board is fixed on the inner wall of a concrete water tank through fasteners, and a water storage inner liner is formed inside the water tank to avoid direct contact between tap water and the aging concrete water tank wall surface and prevent leakage. The applicant found that in the subsequent practice process, the construction efficiency of the hot melt connection between the fixing block and the PE soft board is low, and the professional degree of operation of construction workers is required to be high. An unqualified hot melt fixing process will cause the soft board to separate from the inner wall of the water tank and form a gap between the two. Moreover, since the soft boards are not completely sealed 100%, the water in the gap increases with time, and finally the inner liner structure is damaged. Content of the Utility Model

[0003] In order to overcome the above defects of the prior art, the purpose of the utility model is to provide a fixing structure for a water tank inner liner water separation plate, which simplifies the fixing method between the soft board and the inner wall.

[0006] Further, the metal connecting piece has an annular boss protruding towards the water separation plate direction, the annular boss is connected with the adhesive layer, the metal connecting piece is fixed on the water tank wall surface through an expansion bolt, and the expansion bolt is located at the center of the virtual circle surrounded by the annular boss.

[0007] Further, a plurality of convex grooves distributed around the center of the virtual circle are formed on the annular boss, and the convex grooves increase the contact area between the adhesive layer and the metal connecting piece.

[0008] Further, the convex grooves protrude towards / opposite to the direction of the water separation plate.

[0009] Further, a buffer component is further arranged between the expansion bolt and the metal connecting piece.

[0010] Furthermore, a support flange is provided on the outer edge of the annular boss, and the support flange provides support for the outer edge of the metal connector to prevent deformation.

[0011] The beneficial effects of the present utility model are as follows:

[0012] For the fixed structure of the water tank inner liner water separation plate provided by the present utility model, on the one hand, the annular boss is provided on the connector to prevent the bolt head from contacting the water separation plate and affecting the bonding force. On the other hand, the convex grooves are arranged on the annular boss to make up for the weakening of the bonding force under the manual gluing process. Description of the Drawings

[0017] 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.

[0018] The singular forms "a", "the" and "said" used in the specification include the plural forms unless clearly specified. The terms "comprising", "including" and "containing" used in the specification indicate the presence of the claimed features, but do not exclude the presence of one or more other features. The term "and / or" used in the specification includes any and all combinations of one or more of the related listed items.

[0019] In the specification, when it is stated that one 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 the other element, or there may be intermediate elements. In the specification, when a feature is arranged "adjacent" to another feature, it may mean that the feature has a part overlapping with the adjacent feature or a part located above or below the adjacent feature.

[0020] It can be understood that although terms such as "first", "second", etc. may be used herein to describe different elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a first element can be referred to as a second element without departing from the teachings of the concept of the present application.

[0021] Exemplary embodiments of the present application will be described hereinafter with reference to the accompanying 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 denote the same or functionally identical elements.

[0022] Reference Figure 1 Referring to the shown metal connector, the metal connector 200 is generally in a disc shape as a whole, and a bolt hole 210 is provided at its center. An annular boss 220 protruding towards the water separation plate 100 is provided on the outer periphery of the bolt hole 210. A plurality of convex grooves 221 distributed circumferentially along the annular boss 220 are arranged on the annular boss 220.

[0023] With combined reference Figure 2 , the metal connector 200 is fixed on the pool wall surface 300 by passing an expansion bolt 400 through the bolt hole 210. Since the fixing of one end of the metal connector 200 is achieved by clamping the bolt head 401 of the expansion bolt 400 on the bolt hole 210, the bolt head 401 will protrude from the surface of the metal connector 200 and affect its fitting with the water separation plate 100. Therefore, a raised structure is created on the joint side of the metal connector 200 and the water separation plate 100 through the annular boss 220, so that the bolt head 401 is received and hidden at the central position of the annular boss 220. Specifically, the annular boss 220 is connected to the water separation plate 100 through an adhesive layer 1. Different from the original hot melt construction, the adhesive layer 1 is arranged on the annular boss 220 by manual coating, and its bonding force is smaller than that of hot melt. Therefore, a plurality of convex grooves 221 arranged circumferentially around the center of the metal connector 200 are provided on the annular boss 220. The center point can be the bolt hole 210.

[0024] In the first embodiment, the convex groove 221 protrudes towards the water separation plate 100, thus increasing the contact area between the annular boss 220 and the bonding layer 1 and enhancing the bonding force.

[0025] In another embodiment, the convex groove 221 protrudes towards the direction of the pool wall surface 300, and the hollow groove structure on the back of the convex groove 221 can also increase the contact area with the bonding layer 1 and enhance the bonding force.

[0026] In order to prevent the expansion bolt from crushing the metal connector 200 when driving into the pool wall surface 300, a buffer member 211 is further provided on the bolt hole 210, and the buffer member 211 can be rubber or foam.

[0027] At the outer edge of the annular boss 220, a support edge 230 extending in the direction opposite to the protruding direction of the annular boss 220 is further provided, and the support edge 230 provides support for the outer edge of the metal connector 200. When the water separation inner tank is filled with liquid, the water separation plate 100 will exert a strong pressure outward, that is, towards the direction of the pool wall surface 300, so as to prevent the metal connector 200 from being crushed and deformed through the support edge 230.

[0028] The water separation plate 100 can be made of food-grade PE plastic, and the bonding layer 1 can be made of one-component silicone structural adhesive or two-component composite silicone.
