Abstract
Description
Technical Field
[0001] This utility model relates to the field of roof construction technology, and in particular to a special anti-slip polymer self-adhesive roll material for roof expansion joints. Background Technology
[0002] Expansion joints, or partition joints, are cracks and gaps that occur in rigid waterproofing layers during large-area construction due to external forces, temperature and humidity changes, structural deformation, and other factors. Rigid waterproofing layers are prone to cracking and leakage during large-area construction due to external forces, temperature and humidity changes, and structural deformation. Therefore, the deformation capacity of the waterproofing layer should be considered during the design phase, and necessary structural or construction measures should be taken to avoid or mitigate cracking and achieve the desired waterproofing effect.
[0003] Currently, roof expansion joints are traditionally installed using a hot-melt method. However, excessive hot-melt application can result in an unsightly roof surface. Furthermore, the expansion and contraction of the roof expansion joints may break the waterproof membrane, increasing subsequent maintenance costs. If the hot-melt application is too light, while it may achieve an aesthetically pleasing result, the membrane may detach due to weak adhesion, and external rainwater may seep into the area, thus reducing the waterproofing effect of the roof expansion joints.
[0004] Therefore, it is necessary to find a special anti-slip polymer self-adhesive roll material for roof expansion joints to solve the problems mentioned above. Utility Model Content
[0005] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a special anti-slip polymer self-adhesive roll material for roof expansion joints.

[0007] By adopting the above technical solution, and by setting the prefabricated roof panels to a structure that is high in the middle and low on both sides, rainwater on the surface of the anti-aging board can be quickly drained, thereby reducing water accumulation on the roof after the panels are laid around the perimeter.
[0008] In a preferred embodiment, the bottom of the prefabricated roof panel is fixedly connected with reinforcing ribs at equal intervals, and each reinforcing rib has a round hole inside, into which a tensile anchor rod is inserted.
[0009] By adopting the above technical solution, and through the combined use of round holes, reinforcing ribs, and tensile anchors, stress can be dispersed, thereby increasing the tensile strength of the polymer roll material.

[0012] In a preferred embodiment, the adhesive coating is composed of raw materials such as active silicon, cement, and active inorganic mixtures.

[0016] In a preferred embodiment, anti-tensile rings are fixedly installed on both sides of the prefabricated roof panel, and the reinforcing ribs are connected to the concrete pouring body by anti-tensile anchor rods.
[0017] By adopting the above technical solution and adding tensile rings, the tensile strength of prefabricated roof panels can be further increased.
[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0019] 1. In this utility model, a polymer roll material is applied to the outer surface of the prefabricated roof panel. The polymer roll material has sufficient extension space to avoid thermal expansion and contraction that could break the sealing roll material, thereby reducing subsequent maintenance costs. By setting the prefabricated roof panel with a structure that is high in the middle and low on both sides, rainwater on the surface of the anti-aging board can be quickly drained, thereby reducing water accumulation on the roof after the surrounding area is covered. In a humid environment, the active substances in the adhesive coating will penetrate into the concrete casting and react chemically with the calcium ions in the concrete casting to generate water-insoluble calcium silicate crystals. These crystals fill the capillary channels, making the concrete casting denser, thereby achieving a better waterproof effect.
[0020] 2. In this utility model, by using the round hole, reinforcing rib and tensile anchor rod in combination, when the polymer roll is subjected to external tensile force, the round hole and tensile anchor rod can disperse the stress, thereby increasing the tensile strength of the polymer roll.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0027] Reference Figure 1-4A special anti-slip polymer self-adhesive roll material for roof expansion joints includes a prefabricated roof panel 1, a polymer roll material 102 laid on top of the prefabricated roof panel 1, and an anti-aging board 101 laid on top of the polymer roll material 102. The polymer roll material 102 is fully adhered to the side in contact with the prefabricated roof panel 1. The edges of the prefabricated roof panel 1 are coated with an adhesive coating 103. The surface of the prefabricated roof panel 1 adopts a slightly curved structure. The polymer roll material 102 is made of butyl polymer. The polymer roll material 102 is applied to the outer surface of the prefabricated roof panel 1. The polymer roll material 102 has sufficient extension space to avoid thermal expansion and contraction breaking the sealing roll material, thereby reducing subsequent maintenance costs. Furthermore, the polymer roll material 102 is made of butyl polymer, which has strong tensile strength, thus ensuring the stability of the polymer roll material 102 in windy weather. By setting the prefabricated roof panel 1 with a structure that is high in the middle and low on both sides, rainwater on the surface of the anti-aging board 101 can be quickly drained, thereby reducing water accumulation on the roof after the surrounding area is covered. In a humid environment, the active substances in the adhesive coating 103 will penetrate into the concrete pouring body 4 and react chemically with the calcium ions in the concrete pouring body 4 to generate water-insoluble calcium silicate crystals. These crystals fill the capillary channels, making the concrete pouring body 4 dense, thereby achieving a better waterproof effect.
[0028] Specifically, the bottom of the prefabricated roof panel 1 is fixedly connected with reinforcing ribs 2 at equal intervals. Each reinforcing rib 2 has a round hole 3. Through the combined use of the round hole 3, the reinforcing rib 2 and the tensile anchor rod, when the polymer roll 102 is subjected to external tensile force, the round hole 3 and the tensile anchor rod can disperse the stress, thereby increasing the tensile strength of the polymer roll 102. Tensile anchor rods are inserted into each round hole 3. A concrete casting body 4 is poured at the bottom of the prefabricated roof panel 1 and below the adhesive coating 103. The concrete casting body 4 is in contact with the adhesive coating 103. The adhesive coating 103 is composed of raw materials such as active silicon, cement and active inorganic mixture, so that the adhesive coating 103 has a certain amount of active substances inside.
[0029] Specifically, the anti-aging board 101 and the polymer roll 102 extend along the length of the prefabricated roof panel 1. The anti-aging board 101 reduces the aging and wear caused by external ultraviolet rays and long-term sunlight exposure. The thickness of the prefabricated roof panel 1 is 0.7-0.9 mm, and the thickness of the adhesive coating 103 is 0.3-0.5 mm. Tensile rings 5 are fixedly installed on both sides of the prefabricated roof panel 1 to further increase the tensile strength of the prefabricated roof panel 1. The reinforcing rib 2 is connected to the concrete pouring body 4 by tensile anchor rods.
[0030] Working principle: First, a polymer roll material 102 is applied to the outer surface of the prefabricated roof panel 1. The polymer roll material 102 has sufficient extension space to prevent thermal expansion and contraction from breaking the cover roll material. Furthermore, by setting the prefabricated roof panel 1 with a structure that is higher in the middle and lower on both sides, rainwater on the surface of the anti-aging board 101 can be quickly drained, thereby reducing water accumulation on the roof after the surrounding area is covered. In humid environments, the active substances in the adhesive coating 103 penetrate into the concrete pouring body 4 and react with calcium ions in the concrete pouring body 4. The reaction produces water-insoluble calcium silicate crystals. These crystals fill the capillary channels, making the concrete pouring body 4 denser, thus achieving a better waterproof effect. Through the combined use of the round holes 3, reinforcing ribs 2, and tensile anchors, when the polymer roll 102 is subjected to external tensile force, the round holes 3 and tensile anchors can disperse the stress, thereby increasing the tensile strength of the polymer roll 102. Moreover, the polymer roll 102 is made of butyl polymer material, which has strong tensile strength, thus ensuring the stability of the polymer roll 102 in windy weather.
