Abstract
Description
Technical Field
[0001] This utility model belongs to the field of building waterproofing technology, and relates to a parapet wall waterproofing and drainage structure. Background Technology
[0002] Currently, existing parapet wall waterproofing structures suffer from problems such as poor sealing, easy leakage, cumbersome installation, and weak adaptability to thermal expansion and contraction. There is an urgent need to design a new type of parapet wall waterproofing structure. Utility Model Content
[0003] The purpose of this utility model is to solve the above problems and provide a parapet wall waterproofing and drainage structure.
[0004] To achieve the above objectives, this utility model provides a parapet wall waterproofing and drainage structure, including two long side frames and two short side frames arranged opposite to each other, with the two ends of the short side frames detachably connected to the two long side frames respectively.
[0005] The long frame has a vertical mounting groove, the short frame has a protrusion that matches the vertical mounting groove, the long frame has a first inclined surface, and the short frame has a second inclined surface. When the protrusion is inserted into the vertical mounting groove, the first and second inclined surfaces press and contact each other.
[0006] Furthermore, the long frame is also provided with a limiting hole, and the protrusion is provided with a second limiting hole;
[0007] It also includes a limiting and fixing component, which has a first limiting part that cooperates with a limiting hole, and a second limiting part that cooperates with a second limiting hole.
[0008] Furthermore, the long and short borders are equipped with curved drainage surfaces.
[0009] The beneficial effects of this utility model are as follows:
[0010] This utility model, through the above-mentioned matching installation of the long frame and the short frame, is more convenient to install, has better sealing performance, and superior water-proof performance compared to the existing water-proof structures. Attached Figure Description

[0018] To more clearly illustrate the embodiments of this utility model or the technical solutions in the prior art, the drawings used in the embodiments will be briefly described below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without any creative effort.
[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described in detail here, but the embodiments of the present invention are not limited to the following embodiments.
[0020] Combination Figures 1-7 As shown, this utility model provides a parapet wall waterproofing and drainage structure, including two long side frames 1 and two short side frames 2 arranged opposite each other. The two ends of the short side frames 2 are detachably connected to the two long side frames 1 respectively. The two ends of the long side frames 1 and the two short side frames 2 are connected end to end to form a long-short-long-short square structure. The long side frames 1 and the short side frames 2 are provided with arc-shaped drainage surfaces 4 for drainage.
[0021] According to one embodiment of this utility model, a vertical mounting groove 11 is provided on the long frame 1, and a protrusion 21 that cooperates with the vertical mounting groove 11 is provided on the short frame 2. A first inclined surface 12 is provided on the long frame 1, and a second inclined surface 22 is provided on the short frame 2. When the protrusion 21 is inserted into the vertical mounting groove 11, the first inclined surface 12 and the second inclined surface 22 press into contact. In this embodiment, the inclination directions of the first inclined surface and the second inclined surface 22 are opposite, that is, along the vertical direction, the first inclined surface gradually inclines outward, and the second inclined surface gradually inclines inward. This arrangement ensures a smoother installation contact while maintaining a tight seal.
[0022] In addition, a limiting hole 13 is provided on the long frame 1, and a second limiting hole 23 is provided on the protrusion 21. It also includes a limiting fastener 3, which has a first limiting part 31 that cooperates with the limiting hole 13, and a second limiting part 32 that cooperates with the second limiting hole 23.
[0023] The limiting fastener 3 further secures the long frame 1 and the short frame 2, ensuring structural stability and sealing.
[0024] The above description is merely one embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
