Description

Technical Field

[0001] This utility model relates to the field of building waterproofing technology, specifically to a fastening device for building roof waterproofing membrane. Background Technology

[0002] The “building roof waterproofing membrane” involved in this solution refers to a functional material laid on the surface of the roof base layer to prevent rainwater and snowmelt from penetrating into the building interior. It is usually based on high molecular polymers (such as TPO, PVC) or modified bitumen, and is bonded to the base layer by self-adhesion, hot melt or adhesive methods to form a continuous waterproof barrier. It is the core component of the roof waterproofing system.

[0003] In existing technologies, the fixing of waterproof membranes mostly relies on simple pressure plates combined with steel nails or bolts, but this has the following problems: First, traditional pressure plates only fix the membrane through planar pressure, resulting in insufficient penetration depth and easy displacement of the membrane due to factors such as wind and thermal expansion and contraction; second, the sealing performance between the pressure plate and the substrate is weak, allowing moisture to easily penetrate along the gap between the pressure plate and the substrate, corroding the membrane or the substrate; third, the lack of a stable base pre-connected to the substrate makes the pressure plate prone to loosening after long-term use. Therefore, there is an urgent need for a waterproof membrane fastening device that provides reliable fixing, excellent sealing, and flexible installation. Utility Model Content

[0004] The purpose of this utility model is to provide a fastening device for waterproof roofing membranes. Through structural optimization, it solves the problems of easy displacement of the membrane, poor sealing and insufficient stability of the base in the existing technology, so as to achieve efficient and long-lasting fixation of the waterproof membrane.

[0005] The technical solution provided by this utility model is a fastening device for waterproof membrane of building roof, including a pressure plate and a fastener. The fastener is used to fix the pressure plate to the roof base layer. The bottom surface of the pressure plate is provided with at least one downward protruding piercing part, and the top of the piercing part is a tip for piercing and limiting the waterproof membrane.

[0006] The pressure plate has an installation hole for the fastener to pass through, and the pressure plate has a downwardly recessed sealing groove around the corresponding installation hole, and an elastic sealing ring is embedded in the sealing groove.

[0007] The compression plate is equipped with an independent base, which is pre-embedded or bonded to the roof base layer, and the base is provided with threaded holes that mate with the fasteners.

[0008] As a preferred technical solution of this utility model, the puncture part is one of a conical tooth, a saw tooth, or a wavy protrusion, and multiple puncture parts are provided and arranged at intervals along the length or width direction of the compression tablet.

[0009] As a preferred embodiment of the present invention, the cross-section of the compression tablet is inverted "U" shape, with downwardly extending side wings on both sides, and the puncture part is disposed between the two side wings below the compression tablet.

[0010] As a preferred embodiment of this utility model, the bottom of the side wing is bent inward to form a rolled edge, and the outer side of the rolled edge is provided with anti-slip texture.

[0011] As a preferred embodiment of this utility model, the mounting hole is an elliptical or elongated hole, which makes the position of the pressure plate relative to the fastener adjustable.

[0012] As a preferred embodiment of this utility model, the sealing groove is an annular groove provided on the outside of the mounting hole, and the elastic sealing ring is an "O" ring.

[0013] As a preferred technical solution of this utility model, the pressure plate is provided with a sealing buckle that engages with the sealing groove, and the top of the sealing buckle is a dome whose height gradually decreases from the middle to the edge.

[0014] As a preferred technical solution of this utility model, the pressing sheet is an integral structure formed by stamping metal sheet.

[0015] As a preferred technical solution of this utility model, the bottom and sides of the base are provided with wave-shaped grooves for increasing friction, and the sides of the base are provided with multiple weight-reducing holes for weight reduction and auxiliary fixation on both sides of the threaded hole.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. High reliability of fixation: The piercing part (conical teeth, serrations, etc.) on the bottom surface of the compression plate can pierce the waterproof membrane and embed it into the roof base layer, forming a double fixation with the fasteners to prevent the membrane from shifting due to external forces;

[0018] 2. Excellent sealing performance: The annular sealing groove around the mounting hole is inlaid with an "O"-shaped elastic sealing ring, which can fill the gap between the pressure plate and the fastener, prevent water vapor penetration, and protect the roll material and the roof base layer;

[0019] 3. High installation flexibility: The oval or elongated mounting holes allow for fine adjustment of the pressure plate along the length or width direction, adapting to the error of roll material laying and reducing construction difficulty;

[0020] 4. Excellent structural stability: The independent base is pre-embedded or bonded to the roof base. The wavy groove at the bottom increases friction, and the weight-reducing holes on the side serve both to reduce weight and assist in fixing. Combined with threaded holes and fasteners, the overall anti-loosening ability is significantly improved.

[0021] 5. Easy and durable processing: The tablets are made of metal sheet by stamping and forming in one piece. The rolled edges and anti-slip texture on the sides further enhance the contact stability with the roof base and extend the service life. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1:

[0033] As per the instruction manual Figure 1-5 As shown, this embodiment provides a fastening device for a building roof waterproof membrane, including a pressure plate 1 and a fastener 2. The fastener 2 is used to fix the pressure plate 1 to the roof base layer 3, which is suitable for new roofs or scenarios where pre-embedded bases 8 are allowed.

[0034] In this embodiment, the base 8 is pre-embedded in the roof concrete base layer by construction adhesive or cement grout. Its bottom wavy groove 14 is tightly engaged with the roof base layer 3, the side weight reduction hole 15 reduces the weight of the base 8, and the connection strength is increased by filling with concrete, etc.

[0035] During construction, the waterproof membrane is laid to the designed position, covering the puncture part 4 on the bottom surface of the pressure plate 1; then the pressure plate 1 is aligned with the threaded hole 9 of the base 8, so that the mounting hole 5 is coaxial with the threaded hole 9 of the base 8. A matching bolt is selected as the fastener 2, which passes through the mounting hole 5 and is threadedly connected to the base 8. If the position of the pressure plate 1 needs to be finely adjusted, the pressure plate 1 can be slid along the strip mounting hole 5 to the appropriate position and then the bolt is tightened.

[0036] In this embodiment, the side wings 10 with an inverted "U" shape on both sides of the pressure plate 1 are attached to the upper surface and edge of the roll material, and the anti-slip texture 12 of the inward rolled edge 11 increases the friction between the roll material and the waterproof roll material. At the same time, the piercing part 4 (in this embodiment, it is a conical tooth, arranged at 5cm intervals and set around the mounting hole 5) pierces the roll material and is embedded in the base 8 to achieve mechanical fixation.

[0037] In this embodiment, the "O"-shaped sealing ring in the sealing groove 6 is deformed by the bottom of the sealing buckle 13 when the sealing buckle 13 is installed, filling the gap between the sealing buckle 13 and the fastener 2 of the pressure plate 1 located above the pressure plate 1, and the dome structure at the top of the sealing buckle 13 guides water.

[0038] Example 2:

[0039] This embodiment provides a fastening device for building roof waterproof membrane, including a pressure plate 1 and a fastener 2. The fastener 2 is used to fix the pressure plate 1 to the roof base layer 3, which is suitable for existing roof renovation or roof base layer 3 that is not suitable for pre-embedding.

[0040] In this embodiment, the base 8 is omitted, and the pressure plate 1 is directly fixed to the roof base layer 3 (such as wood, metal, or concrete leveling layer) using fasteners 2 (stainless steel rivets or expansion bolts in this embodiment). The structure of the pressure plate 1 is the same as in Embodiment 1: the piercing part 4 pierces and fixes the plate, and the mounting hole 5 (elongated) allows for adjustment of the position along the roll joint direction; the "O" ring in the sealing groove 6, in conjunction with the sealing buckle 13 (which snaps into the sealing groove 6), enhances the seal. The rivet or bolt passes through the mounting hole 5 and into the roof base layer 3 for quick fixing.

[0041] Working principle

[0042] 1. Mechanical puncture fixation: The puncture part 4 (conical teeth) on the bottom surface of the pressure plate 1 punctures the waterproof membrane and embeds into the roof base layer 3, which together with the fastener 2 restricts the planar displacement of the membrane.

[0043] 2. Sealing and protection: The annular sealing groove 6 around the mounting hole 5 is inlaid with an elastic "O" ring. After the fastener 2 is tightened, the sealing ring deforms and fills the gap, blocking the penetration path of rainwater or water vapor along the pressure plate 1 and the roof base layer 3.

[0044] 3. Adjustable position and stable connection: The elliptical mounting hole 5 allows for fine adjustment of the pressure plate 1 to accommodate construction errors; the independent base 8 is pre-embedded or bonded to the roof base layer 3, and the wavy groove 14 increases friction and the weight reduction hole 15 assists in fixing. It is then connected to the pressure plate 1 by fastener 2 through thread, forming a stable force transmission chain of "roof base layer 3-base 8-pressure plate 1" to avoid loosening after long-term use;

[0045] 4. Enhanced contact stability: The side wings 10 and inner rolled edge 11 of the inverted "U" shaped pressure plate 1 are designed to increase the contact area with the roll material. The anti-slip texture 12 on the outer edge 11 further enhances the friction and prevents the roll material from sliding relative to the pressure plate 1.

[0046] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
