Description

Technical Field

[0001] This utility model relates to the field of waterproof membrane technology, and in particular to a corrosion-resistant waterproof membrane with an installation overlap structure. Background Technology

[0002] Waterproof membrane is a rollable sheet-like waterproof material, mainly used in building walls, roofs, tunnels, highways, landfills, etc., to resist the penetration of external rainwater, groundwater and other water sources. Waterproof membrane is usually provided in the form of rolls of a certain size. A single roll cannot completely cover the entire area that needs waterproofing. By overlapping, multiple rolls can be connected to make the entire waterproof layer a continuous whole.

[0003] In the current technology for laying waterproof membranes, adjacent waterproof membranes need to be overlapped and welded together. However, this overlap may result in installation deviations and poor waterproofing performance.

[0004] An existing patent (publication number: CN216810331U) discloses a waterproof membrane overlap structure. By using overlap blocks and overlap grooves together, the possibility of overlap misalignment is reduced. The use of overlap components makes it easy to fix the overlap blocks inside the overlap grooves. The use of drive worm and drive worm wheel in the disassembly drive assembly improves the stability of the overlap.

[0005] To address the aforementioned issues, while existing patents can achieve overlapping of waterproof membranes through the cooperation of components such as drive worm gears, their application is limited in practice because the required overlap length of the waterproof membrane is relatively long and often needs to be cut according to the specific conditions of the installation site. Summary of the Invention

[0006] The purpose of this utility model is to provide a corrosion-resistant waterproof membrane with an installation overlap structure, which can quickly overlap between two adjacent membranes and improve the sealing of the overlap. It is suitable for large-area application and can be cut according to the application situation to avoid excessive limitation of use, thereby solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a corrosion-resistant waterproof membrane with an installation overlap structure, comprising a first waterproof membrane, a first overlap block fixedly installed at one end of the first waterproof membrane, a second overlap block fixedly installed at the front end of the first overlap block, a second waterproof membrane fixedly installed at one end of the second overlap block, and an overlap mechanism provided inside the second overlap block.

[0008] The overlapping mechanism includes a slot, which is formed on the outer wall of the first overlapping block facing the second overlapping block, and a first fixing adhesive is embedded inside the slot. A fixing block is fixedly installed on the outer wall of the second overlapping block facing the first overlapping block, and an elastic block is fixedly installed at the front end of the fixing block corresponding to the position of the slot.

[0009] Preferably, a sealing block is fixedly installed on the outer wall of both the first overlapping block and the second overlapping block, and a second fixing adhesive is embedded in the outer wall of the sealing block.

[0010] Preferably, the slots are evenly spaced at equal intervals relative to the outside of the first overlapping block, and the slots are bonded to the first fixing adhesive.

[0011] Preferably, a connecting mechanism is provided on one side of the first overlapping block. The connecting mechanism includes a connecting block, which is fixed to the outer wall of the first overlapping block, and a connecting block is fixedly installed at the end of the connecting block away from the first overlapping block.

[0012] Preferably, a limiting groove is provided inside the second overlapping block at the position corresponding to the connecting block, and a third fixing adhesive is embedded inside the limiting groove.

[0013] Preferably, the connecting block is internally fitted with a horizontal metal wire, and a vertical metal wire is fixedly installed at one end of the horizontal metal wire that passes through the connecting block.

[0014] Preferably, the horizontal metal wire extends into the interior of the first overlapping block, and the horizontal metal wire is perpendicular to the vertical metal wire.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model, through the misalignment of the first overlapping block and the second overlapping block, combined with the engagement of the elastic card block and the card slot, and further reinforced and sealed by the dissolved first fixing adhesive, can quickly overlap between two adjacent rolls and improve the sealing performance of the overlap. It is suitable for large-area paving and can be cut according to the paving situation to avoid being too limited in use.

[0017] 2. This utility model improves the tensile strength between two rolls by inserting connecting blocks and connecting blocks into the limiting groove, thereby improving the toughness of the overall roll after it is laid.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution:

[0029] Please see Figures 1 to 5A corrosion-resistant waterproof membrane with an overlapping installation structure includes a first waterproof membrane 1, a first overlapping block 3 fixedly installed at one end of the first waterproof membrane 1, a second overlapping block 4 fixedly installed at the front end of the first overlapping block 3, a second waterproof membrane 2 fixedly installed at one end of the second overlapping block 4, and an overlapping mechanism 5 provided inside the second overlapping block 4; the overlapping mechanism 5 includes a slot 501, which is formed on the outer wall of the first overlapping block 3 facing the second overlapping block 4, and a first overlapping block 4 is embedded inside the slot 501. A fixing adhesive 502 is used. A fixing block 503 is fixedly installed on the outer wall of the first overlapping block 3 facing the second overlapping block 4. An elastic locking block 504 is fixedly installed on the front end of the fixing block 503 corresponding to the position of the locking groove 501. A sealing block 505 is fixedly installed on the outer wall of both the first overlapping block 3 and the second overlapping block 4. A second fixing adhesive 506 is embedded in the outer wall of the sealing block 505. The locking grooves 501 are evenly spaced at equal intervals relative to the outside of the first overlapping block 3. The locking grooves 501 are bonded to the first fixing adhesive 502.

[0030] By adopting the above technical solution, when two adjacent rolls overlap, such as the first overlapping block 3 of the first waterproof roll 1 and the second overlapping block 4 of the second waterproof roll 2, the overlap seam is misaligned to improve the sealing performance. Then, during installation, the elastic clip 504 is pressed and the fixing block 503 is inserted into the slot 501 for initial engagement. At the same time, the sealing block 505 covers the overlap seam. A blowtorch or hot air gun is used to evenly heat the overlap area, allowing the first fixing adhesive 502 and the second fixing adhesive 506 to melt and achieve an adhesive effect. Under tight adhesion, the elastic clip 504 and the slot 501 are engaged, preventing loosening. The rubber elastic clip 504 improves the sealing performance, and the sealing block 505 further improves the sealing performance of the overlap. This facilitates large-area block laying and cutting, and can be used according to specific conditions.

[0031] Specifically, such as Figure 2 , Figure 3 and Figure 6 As shown, a connecting mechanism 6 is provided on one side of the first overlapping block 3. The connecting mechanism 6 includes a connecting block 601, which is fixed to the outer wall of the first overlapping block 3. A connecting block 602 is fixedly installed at the end of the connecting block 601 away from the first overlapping block 3. A limiting groove 603 is opened inside the second overlapping block 4 corresponding to the position of the connecting block 601. A third fixing adhesive 604 is embedded inside the limiting groove 603. A metal horizontal wire 605 is embedded inside the connecting block 601. A metal vertical wire 606 is fixedly installed at the end of the metal horizontal wire 605 that passes through the connecting block 602. The metal horizontal wire 605 passes through the interior of the first overlapping block 3. The metal horizontal wire 605 and the metal vertical wire 606 are perpendicular to each other.

[0032] By adopting the above technical solution, when the first overlapping block 3 and the second overlapping block 4 are attached, the connecting block 601 and the connecting block 602 enter the limiting groove 603 to achieve the limiting effect, thereby improving the tensile strength between the first overlapping block 3 and the second overlapping block 4. With the cooperation of the metal horizontal wire 605 and the metal vertical wire 606, the tensile strength between the first waterproof membrane 1 and the second waterproof membrane 2 is improved. At the same time, the third fixing adhesive 604 improves the tightness of the connection and the sealing of the overall space after it melts.

[0033] Working principle: The first waterproof membrane 1 and the second waterproof membrane 2 correspond to and are connected as a whole with the first overlapping block 3 and the second overlapping block 4. Pressing the second overlapping block 4 allows the fixing block 503 and the elastic locking block 504 to enter the locking groove 501 and engage. Then, the joint is covered by the sealing block 505, which is made of the same material as the first waterproof membrane 1. The overlapping area is heated by a heating device such as a blowtorch, which melts the first fixing adhesive 502 and the second fixing adhesive 506 to achieve an adhesive effect. At the same time, during the overlapping, the connecting block 601 and the connecting block 602 enter the limiting groove 603 and are simultaneously melted by the third fixing adhesive 604 to further improve the adhesive effect. The cooperation of the metal horizontal wire 605 and the metal vertical wire 606 can improve the tensile strength between the first waterproof membrane 1 and the second waterproof membrane 2. The first fixing adhesive 502, the second fixing adhesive 506 and the third fixing adhesive 604 can be hot melt adhesive or asphalt or similar heat-melting sealing adhesive materials.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
