Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to weather-resistant waterproof membrane. Background Technology

[0002] Waterproof membrane is a flexible material used in building waterproofing projects. It is laid on the building surface to form a continuous waterproof layer to prevent water penetration.

[0003] To effectively prevent leaks, existing sheet metal roofs are usually covered with exposed waterproof membranes. Since cement cannot be laid on sheet metal roofs, the materials used to make these waterproof membranes are usually chosen to have good weather resistance.

[0004] However, in actual use, because the waterproof membrane is relatively soft, the adhesive layer used to bond with the sheet metal roof has a narrow concave surface formed by wrinkles during transportation and handling. When water vapor seeps from inside the house into the concave surface of the waterproof membrane and the sheet metal roof surface, the waterproof membrane will expand and soften, causing the waterproof membrane to gradually detach from the sheet metal roof, resulting in a decrease in the waterproof effect of the waterproof membrane.

[0005] To address the above issues, a weather-resistant waterproof membrane technology solution is proposed. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a weather-resistant and waterproof membrane.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a weather-resistant waterproof membrane, comprising a main body, the main body comprising an adhesive layer that can adhere to the roof surface, a parting mesh plate fixedly disposed within the adhesive layer, the parting mesh plate dividing the adhesive layer into several parts, each part of the adhesive layer having a groove, and one side of the groove being fixedly filled with a heat-expandable foam block.

[0008] The present invention is further configured such that each adhesive layer is structured to surround the foam block, and a gap is left to allow the foam block to expand toward the other side of the groove.

[0009] The present invention is further configured such that: the foam block has a frustum-shaped structure, and the upper bottom of the frustum-shaped structure is located on the side of the adhesive layer that adheres to the roof surface.

[0010] The present invention is further configured such that the parting mesh plate has a honeycomb structure.

[0011] The present invention is further configured such that: a waterproof layer and a sun-protective layer are provided sequentially from the inside to the outside on one side of the adhesive layer.

[0012] The present invention is further configured such that a release layer that can be separated from the adhesive layer is provided on one side of the adhesive layer.

[0013] In summary, this utility model has the following beneficial effects: through the expansion of the foam block, it effectively fills the long concave surfaces on the surface of the waterproof membrane caused during transportation and handling, thereby effectively maintaining the weather resistance of the waterproof membrane.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Weather-resistant waterproof membrane, such as Figure 1 as well as Figure 2 As shown, the device includes a main body 1, which includes an adhesive layer 13 that can adhere to the roof surface. On one side of the adhesive layer 13, a waterproof layer 12 and a sun protection layer 11 are sequentially provided from the inside to the outside. On the other side of the adhesive layer 13, a release layer 14 that can be separated from the adhesive layer 13 is provided. A parting mesh 2 is fixedly installed inside the adhesive layer 13, which divides the adhesive layer 13 into several parts. Each part of the adhesive layer 13 has a groove 131, and the side of the groove 131 closest to the sun protection layer 11 is fixedly filled with a heat-expandable foam block 3. In this application, the sun protection layer 11 is made of modified bitumen material, the waterproof layer 12 is made of TPO material, and the parting mesh 2 is a fiberglass mesh with a honeycomb structure. During the production of the adhesive layer 13, hot melt bitumen is poured onto the fiberglass mesh to form the adhesive layer 13.

[0019] like Figure 1 as well as Figure 2As shown, during installation, the release layer 14 is removed, and then the waterproof membrane is laid on the roof surface. When a long concave surface appears on the surface of the waterproof membrane, during the hot-melt process of the waterproof membrane, several foam blocks 3 expand toward the gap formed by the long concave surface, thereby filling the position of the long concave surface and assisting in adhering to the roof surface. Through the expansion of the foam blocks 3, the long concave surface generated on the surface of the waterproof membrane during transportation and handling is effectively filled, thereby effectively maintaining the weather resistance of the waterproof membrane.

[0020] To improve the waterproofness of the adhesive layer 13 at the concave surface, each adhesive layer 13 is structured to surround the foam block 3, with a gap left to allow the foam block 3 to expand toward the other side of the groove 131. That is, the expansion of the foam block 3 is used to push the adhesive layer 13 near the expansion position of the foam block 3 toward the roof. In order to apply the expansion force of the foam block 3 more evenly to the surface of the adhesive layer 13, the foam block 3 is shaped like a frustum, and the upper bottom of the frustum is set near the side of the adhesive layer 13 that is attached to the roof surface.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0022] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
