Description

Technical Field

[0001] This utility model relates to the field of building waterproofing engineering technology, and more specifically, to a self-adhesive waterproof membrane pre-laying component for internal corners. Background Technology

[0002] The inner corner of a wall is the corner formed by the perpendicular intersection of two walls in a building structure. Due to its special structure, it is prone to leakage due to problems such as uneven laying of the waterproofing membrane and large gaps in the joints. It is a key weak point in waterproofing projects.

[0003] Current methods for waterproofing inside corners mostly employ "on-site cutting + manual pasting," which has the following drawbacks:

[0004] 1. On-site cutting accuracy depends on the operator's experience. The shape of the roll material is difficult to fully adapt to the curvature or angle of the inside corner, which can easily lead to the corners not fitting properly, leaving potential leakage risks.

[0005] 2. When applying the roll material by hand, the pressure between the roll material and the wall substrate is uneven, especially at inside corners, where air bubbles or hollow areas are prone to form, reducing waterproof sealing.

[0006] 3. The construction process is complicated. It requires leveling the base layer of the inside corner, applying a primer, cutting the roll material, positioning and pasting it. The process is complicated and time-consuming, which affects the overall construction efficiency.

[0007] Therefore, there is a need for a waterproof component that can be prefabricated, adapted to internal corner structures, and has a simplified construction process to address the shortcomings of the existing technologies. Utility Model Content

[0008] To address the issues of low precision, poor adhesion, and low construction efficiency in existing wall corner waterproofing construction, a self-adhesive waterproof membrane pre-laying component for corners is provided. This component enables pre-embedded positioning and immediate application upon tearing the membrane, thereby improving the sealing performance and construction efficiency of corner waterproofing.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A pre-laid component for self-adhesive waterproof membrane for internal corners includes an anchor plate, a support frame, an adapter plate, and an adhesive layer;

[0011] The anchor plate is a long strip-shaped structure, with two sets. The two sets of anchor plates are set vertically and are used for pre-embedding inside the wall.

[0012] The support frame is a trapezoidal structure, with several sets evenly distributed between two sets of anchor plates. Its two ends are fixedly connected to the two sets of anchor plates respectively, and it is used to support the connecting adapter plate.

[0013] The adapter plate has a trapezoidal structure with both trapezoidal sides perpendicular. After installation, both sides fit against the inside corner wall to fill the inside corner area. The bottom surface of the adapter plate has a positioning groove that matches the support frame. The adapter plate is snapped onto the support frame through the positioning groove.

[0014] A circular positioning platform is provided at the center line of the support frame. A screw hole is opened inside the positioning platform. A bolt is inserted into the adapter plate, and the tail end of the bolt passes through the adapter plate and is screwed into the screw hole.

[0015] The adhesive layer is located on the outer surface of the adapter plate and is used to adhere and connect the self-adhesive waterproof membrane.

[0016] Furthermore, the adhesive layer includes a release film and a self-adhesive layer; the self-adhesive layer is adhered to the outer surface of the adapter plate, and the outer surface of the self-adhesive layer is removably covered with a release film to protect the adhesiveness of the self-adhesive layer.

[0017] Furthermore, the outer surface of the adapter plate has an arc-shaped structure.

[0018] Furthermore, the adapter plate has a stepped groove inside that is compatible with the bolt and is connected to the positioning groove, and the depth of the stepped groove is greater than the thickness of the nut on the bolt.

[0019] Furthermore, the adhesive layer has through holes, the positions of which correspond to the positions of the stepped grooves.

[0020] Furthermore, the two obtuse angles on the support frame are 120 degrees.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] This invention achieves a stable connection between the component and the wall through pre-embedded anchor plates, avoiding positional deviation during later construction. The trapezoidal structure of the support frame cooperates with the positioning groove of the adapter plate to ensure accurate positioning of the adapter plate while enhancing structural support. The vertical sides and curved outer side of the adapter plate are designed to completely fit the inside corner wall surface, eliminating concave gaps. The self-adhesive layer and release film design of the adhesive layer allow for immediate application after peeling off the film, eliminating the need for on-site application of primer and simplifying the construction process. The stepped groove design of the bolts conceals the bolt nuts, preventing them from protruding and affecting the adhesion of the roll material, further improving waterproof sealing.

[0023] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0035] Example 1:

[0036] like Figures 1 to 8 As shown, this embodiment provides a pre-laid component for self-adhesive waterproof membrane for inside corners, including an anchor plate 2, a support frame 4, an adapter plate 3, and an adhesive layer 1.

[0037] Anchor plate 2 has a long strip structure and two sets are provided. The two sets of anchor plates 2 are set perpendicular to each other and are used to be embedded in the wall to provide a fixed foundation for the entire component and ensure the stability of the connection between the component and the wall.

[0038] The support frame 4 has a trapezoidal structure and is provided in several groups. All support frames 4 are evenly distributed between the two groups of anchor plates 2. The two ends of the support frame 4 are fixedly connected to the two groups of anchor plates 2 respectively. They can be fixed by welding or bolts 6. Its core function is to support and connect the adapter plate 3, and at the same time enhance the structural strength between the anchor plate 2 and the adapter plate 3.

[0039] Furthermore, the two obtuse angles on the support frame 4 are 120 degrees. This angle design can adapt to the stress requirements of most building corners and avoid stress concentration.

[0040] The adapter plate 3 has a trapezoidal structure with its two sides perpendicular to each other. After installation, the two sides of the adapter plate 3 can completely fit against the inside corner wall, filling the concave area at the inside corner and forming a smooth transition surface. The bottom surface of the adapter plate 3 has a positioning groove 5 that matches the support frame 4. The adapter plate 3 is fastened to the support frame 4 through the positioning groove 5 for quick positioning. The adapter plate 3 also has a bolt 6 inserted inside, and a stepped groove 9 that matches the bolt 6 is also provided inside the adapter plate 3. The stepped groove 9 is connected to the positioning groove 5, and the depth of the stepped groove 9 is greater than the thickness of the nut on the bolt 6, which can prevent the nut from protruding and affecting the adhesion between the adhesive layer 1 and the waterproof membrane.

[0041] In addition, the outer side of the adapter plate 3 has an arc-shaped structure. The arc design can reduce the bending stress of the waterproof membrane at the corner and reduce the risk of the membrane cracking.

[0042] The adhesive layer 1 is disposed on the outer side of the adapter plate 3 and is used to adhere and connect the self-adhesive waterproof membrane. Specifically, the adhesive layer 1 includes a release film 11 and a self-adhesive layer 12, wherein the self-adhesive layer 12 is adhered to the outer side of the adapter plate 3, and the release film 11 is detachably covered on the outer side of the self-adhesive layer 12. The function of the release film 11 is to protect the adhesiveness of the self-adhesive layer 12 and prevent the self-adhesive layer 12 from being contaminated before construction.

[0043] Furthermore, the adhesive layer 1 has through holes, the position of which corresponds to the position of the stepped groove 9 on the adapter plate 3, which facilitates the subsequent installation and removal of the bolts 6.

[0044] In addition, a circular positioning platform 7 is provided at the center line of the support frame 4. The positioning platform 7 has a screw hole 8 inside. The bolt 6 on the aforementioned adapter plate 3 passes through the adapter plate 3 and is screwed into the screw hole 8, so as to realize the detachable fixing of the adapter plate 3 and the support frame 4, which facilitates the quick installation of the adapter plate 3 during construction.

[0045] Example 2:

[0046] This embodiment provides the working principle of a self-adhesive waterproof membrane pre-laying component for inside corners: During the wall construction or pouring process, two sets of vertically connected anchor plates 2 are pre-embedded inside the wall at the inside corner, and the center lines of both sides of the support frame 4 are flush with the wall surface; after the wall dries, the adapter plate 3 is clamped onto the support frame 4 through the positioning groove 5 on the bottom surface, and the position of the adapter plate 3 is adjusted so that both sides of the adapter plate 3 are completely attached to the inside corner wall surface; then the bolt 6 is passed through the stepped groove 9 of the adapter plate 3 and screwed into the screw hole 8 of the positioning platform 7 of the support frame 4. After the bolt 6 is tightened, the nut is completely embedded in the stepped groove 9 and does not protrude;

[0047] Remove the release film 11 from the outer adhesive layer 1 of the adapter plate 3, cover the adhesive layer 1 with the self-adhesive waterproof membrane, and use a rubber scraper to evenly scrape and press along the surface of the adapter plate 3 and the inside corners to ensure that the membrane and the self-adhesive layer 12 are completely bonded together without bubbles or hollow areas.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
