Traditional angle processing methods mostly use hand paste, which has low production efficiency, low product quality, and difficult to ensure sealing. In addition, there is a lack of certain positioning structures when connecting with the panel, which is not convenient for construction personnel to install. Utility Model Content

[0020] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0021] See also Figure 1-Figure 5 The utility model provides a molded corner wrap for a cooling tower, which is used to wrap around the joint between two panels on the cooling tower body. The molded corner wrap for the cooling tower is formed by glass fiber reinforced plastics and includes a first edge wrap 1 and a second edge wrap 2 connected to each other. The first edge wrap 1 and the second edge wrap 2 are perpendicular to each other. The connection between the first edge wrap 1 and the second edge wrap 2 forms an angle wrap line 10. The space enclosed by the first edge wrap 1 and the second edge wrap 2 forms a cavity 20 adapted to the outer contour of the panel. The length of the first edge wrap 1 and the second edge wrap 2 along the angle wrap line 10 is A plurality of ridges 3 are protruded in a direction away from the cavity 20, and the inner cavity of the ridges 3 has a large end 31 and a small end 32 that are relatively arranged. The large end 31 is connected to the cavity 20, and the small end 32 is located on the side of the large end 31 away from the cavity 20. A connecting portion 4 is formed between each two adjacent ridges 3 on the first edge 1 and the second edge 2. The connecting portion 4 is fixedly connected to the panel by self-tapping screws. The length L1 of the ridge 3 along the extension direction of the angle line 10 is greater than the length L2 of the connecting portion 4 along the extension direction of the angle line 10.

[0022] The corner wrapping of the utility model cancels the traditional hand-paste processing technology, adopts compression molding, can realize mass production, greatly improves production efficiency, meets the needs of industrial production, and at the same time, compression molding can ensure the accurate and consistent size of the corner wrapping through the precise design of the mold, the product quality is stable and reliable, and the sealing between it and the contact surface of the panel is guaranteed. By setting the convex rib 3, multiple protruding structures are formed on the length direction of the corner wrapping line 10 on the first edge wrapping 1 and the second edge wrapping 2. The protruding structure matches the outer contour of the panel. When installing, when the corner wrapping is covered at the joint of the panel, it can play a good positioning role, which is convenient for construction personnel to quickly put the corner wrapping in place, which is helpful for subsequent installation and fixing. In addition, the corner wrapping is made of glass fiber reinforced plastic material, and the structural strength is guaranteed. When the connecting part 4 is fixedly installed on the outside of the panel by self-tapping screws, the part of the connecting part 4 near the self-tapping screws will be slightly deformed. This deformation is conducive to pulling the convex rib 3 toward the wrapping cavity 20, thereby squeezing and fixing the sealing member (for example, rubber pad) sandwiched between the corner wrapping and the panel, thereby further improving the sealing effect. In this embodiment, the length L1 of the ridge 3 along the direction of the corner line 10 is greater than the length L2 of the connection part 4 along the direction of the corner line 10. In this way, when installing the self-tapping screw, the relatively narrow connection part 4 can more easily pull the ridges 3 on both sides when it is deformed, which helps to press the ridges 3 against the panel. At the same time, the ridge 3 is adapted to the protruding structure on the panel that matches it, which increases the difficulty of the corner relative to the panel along the direction of the corner line 10, and further improves the connection stability between the corner and the panel.

[0023] As a preferred embodiment, the self-tapping screw is connected in the middle of the connecting portion 4, so that the distances from the self-tapping screw to the ridges 3 on both sides are the same, thereby ensuring that the ridges 3 on both sides are subjected to balanced forces to achieve a better sealing effect.

[0024] As a preferred embodiment, the ridge 3 includes a first connecting piece 301, a second connecting piece 302 and a third connecting piece 303, one side of the first connecting piece 301 and the second connecting piece 302 are respectively connected to two adjacent connecting parts 4, the other side of the first connecting piece 301 and the other side of the second connecting piece 302 are respectively connected to the opposite sides of the third connecting piece 303, and a small opening end 32 is formed on the ridge 3 on one side of the third connecting piece 303.

[0025] The connecting portion 4 is a flat plate structure, the angle between the connecting portion 4 and the first connecting piece 301 is α, and the angle between the connecting portion 4 and the second connecting piece 302 is β, wherein 90°<α<180°, 90°<β<180°. By controlling the two angles, when the wrap angle is attached to the panel in a direction perpendicular to the connecting portion 4, the connecting portion between the connecting portion 4 and the first connecting piece 301 and the connecting portion between the connecting portion 4 and the second connecting piece 302 will not prevent the protruding structure on the panel from entering the convex ridge 3, which is convenient for installation.

[0026] As a preferred embodiment, α=β=150°. Further, the third connecting piece 303 and the connecting portion 4 are parallel to each other, so that the first connecting piece 301, the second connecting piece 302 and the third connecting piece 303 together form an isosceles trapezoidal structure for easy production.

[0027] In this embodiment, the convex rib 3 is composed of three interconnected flat plates. In other embodiments, the convex rib 3 can also be composed of more than three flat plates spliced ​​together, and the specific number is not limited. In addition, it can be understood that the convex rib 3 can also be composed of an arc-shaped panel, as long as the inner cavity of the convex rib 3 has a large end 31 and a small end 31, and the large end 31 is connected to the package cavity 20, and the specific arrangement of the convex rib 3 is not limited.

[0028] In this embodiment, the plurality of ridges 3 on the first edge wrapping 1 and the second edge wrapping 2 are arranged at equal intervals along the length direction of the corner wrapping line 10 .

[0029] In addition, during specific processing, a mounting hole can be opened on the connection part 4. When the corner is attached to the panel, the construction personnel can drive the self-tapping screw into the panel through the mounting hole, so as to lock and fix the corner on the panel. As a preferred embodiment, the mounting hole is set in the middle position of the connection part 44, and the distance from the mounting hole to the convex ridges 3 on both sides is the same. Of course, it is also possible not to open the mounting hole in advance. When installing the corner, the self-tapping screw is directly driven into the connection part 4 and the panel to achieve the fixing effect between the two.

[0030] Compared with the traditional hand lay-up process, the cooling tower molded corner of the utility model has higher production efficiency through molding process, can meet the needs of industrial production, and has stable and reliable product quality, which provides a guarantee for sealing the panel joints. At the same time, the setting of the ridge 3 can be adapted to the protruding structure on the panel, which can play a good positioning role, making it convenient for construction personnel to quickly put the corner into place, and increases the difficulty of the corner moving relative to the panel along the direction of the corner line 10, thereby improving the stability of the corner after installation.

[0031] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
