Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waterproof coiled materials, in particular to a waterproof coiled material which is convenient for external corner construction. Background Art
[0002] When waterproofing a roof, waterproofing membranes are often used. During construction, a fire gun is used to melt the surface of the waterproofing membrane, and then the waterproofing membrane is attached to the roof surface and cooled, which effectively prevents leakage from the roof. When encountering a positive angle formed between the roof surface and the pedestal, the existing technology usually waterproofs the positive angle by cutting and overlapping the waterproofing membrane.
[0003] In order to avoid the situation where the roll material is difficult to adhere to the outside corners due to its shape when laying the roof, the existing construction operation is to lay a separate additional layer at each outside corner and then use the roll material to lay the roof. When the roll material encounters a outside corner, the coverage of the roll material on the outside corner can be reduced, thereby improving the convenience of laying.
[0004] When the existing roll materials are laid, due to the certain material elasticity of the roll materials, the roll materials are usually attached to the external corners with a circular bend transition rather than a right-angle bend. Since the size of the bending arc of the roll materials is related to the rigor of the construction of the workers, if the workers are not in place during the construction process, the external corners may be not tight enough due to the large arc of the roll materials laid, resulting in the appearance of leakage points, making the roof prone to water leakage.
[0005] In view of the above problems, a waterproof membrane which is convenient for exterior corner construction is proposed. Utility Model Content
[0006] The utility model aims to solve the problems in the prior art and provides a waterproof roll material which is convenient for the construction of external corners.
[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a waterproof membrane that is convenient for the construction of external corners, including an additional layer for bonding the roof surface and the external corner and two layers of substrate that are respectively bonded to the roof surface along both sides of the external corner until they are superimposed and bonded to the additional layer, the substrate is provided with a cutting opening on the side close to the external corner, the substrate is bent on one side of the cutting opening to form an attachment surface arranged with edges surrounding the external corner, the attachment surface is spaced from the additional layer on one side close to the roof surface to form an embedded groove, the two layers of the substrate are respectively fixedly embedded in the embedded grooves on the other side of the cutting opening, and one layer of the substrate covers the cutting opening of the other layer of the substrate.
[0008] The utility model is further configured as follows: a cutting portion that can be extended and cut to the position of the additional layer attached to the external corner is provided on one side of the additional layer attached to the roof surface. When the additional layer is bonded to the roof surface and the external corner, the additional layer is cut along the cutting portion from the position placed on the roof surface to at least the end of the edge placed on the external corner.
[0009] The utility model is further configured as follows: the cutting portion and the edge of the positive angle are in the same plane, both sides of the cutting portion are chamfered to form a connecting surface, the substrate is arranged in contact with the connecting surface, and the cutting opening is opened at the side edge of the connecting surface.
[0010] The utility model is further configured as follows: the additional layer is shaped into a concave shape by melting on a side of the edge of the external angle close to the roof surface and is bonded to the external angle.
[0011] The utility model is further configured as follows: the two connecting surfaces jointly form a transition surface at the edge position of the positive angle, and one layer of the base material is melt-bonded to the transition surface.
[0012] The utility model is further configured as follows: the additional layer and the base material are subjected to roller pressing at the connection surface.
[0013] In summary, the utility model has the following beneficial effects: the substrate is embedded in the embedded groove at the part of the external corner close to the roof surface, so that the substrate can be more closely attached to the edges on both sides of the external corner during laying, effectively reducing the occurrence of leakage points.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside" and "outside" indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention. Obviously, the embodiments described are only some embodiments of the present invention, rather than all embodiments.
[0020] Waterproof membranes that are convenient for exterior corner construction, such as Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, it includes an additional layer 1 for bonding the roof surface and the external angle, and two layers of substrate 2 respectively bonded to the roof surface along the two sides of the external angle until being superimposed and bonded to the additional layer 1. The substrate 2 is provided with a cutting opening 23 on the side close to the external angle. The substrate 2 is bent on one side of the cutting opening 23 to form an attachment surface 22 arranged to surround the edges of the external angle. The attachment surface 22 is spaced apart from the additional layer 1 on one side close to the roof surface to form an embedded groove 21. The two layers of substrate 2 are respectively fixedly embedded in the embedded groove 21 on the other side of the cutting opening 23, and one layer of substrate 2 covers the cutting opening 23 of the other layer of substrate 2. In this specific embodiment, the cutting opening 23 can be pre-cut when the product is produced, or the substrate 2 can be transported to the roof and then cut on site after construction begins.
[0021] During construction, the additional layer 1 is first burned and attached to the external corner, and then workers successively lay a layer of substrate 2 along the two sides of the external corner. When the substrate 2 is laid on the additional layer 1, the substrate 2 is burned, and the substrate 2 is pulled away from the additional layer 1 so that the substrate 2 is embedded in the embedded groove 21 at the external corner close to the roof surface. Then the remaining substrate 2 is burned and laid. During the entire construction, the curved shape of the substrate 2 at the external corner is reduced in shape by being pulled into the embedded groove 21, so that the substrate 2 can better fit the additional layer 1.
[0022] Practical effect: The base material 2 is embedded in the embedded groove 21 at the part of the external corner close to the roof surface, so that the base material 2 can be more closely attached to the edges on both sides of the external corner during laying, effectively reducing the occurrence of leakage points.
[0023] like Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, specifically, a cutting portion 13 which can be extended and cut to the position where the additional layer 1 is attached to the external corner is provided on one side of the additional layer 1 attached to the roof surface. When the additional layer 1 is bonded to the roof surface and the external corner, the additional layer 1 is cut along the cutting portion 13 from the position on the roof surface to at least the end of the edge placed on the external corner. The curvature generated by the connecting surface 11 is used to effectively improve the convenience of the substrate 2 being embedded in the embedded groove 21. In this specific embodiment, the cutting portion 13 can also be pre-cut when the product is produced, or the substrate 2 can be transported to the roof and then cut on the spot after the construction begins. In the size setting of the additional layer 1, the cutting portion 13 and the edge of the external corner are in the same plane, and the two sides of the cutting portion 13 are chamfered to form a connecting surface 11. The substrate 2 is arranged in contact with the connecting surface 11, and the cutting port 23 is opened at the side edge of the connecting surface 11. At the same time, the additional layer 1 and the substrate 2 can also be rolled at the connecting surface 11 to improve the bonding degree.
[0024] In order to further improve the operation of the substrate 2 embedded in the embedded groove 21 and waterproof the roof together with the additional layer 1, the additional layer 1 is shaped into an inward concave shape by melting and bonded to the external angle at the edge of the external angle close to the roof surface. Specifically, the two connecting surfaces 11 jointly form a transition surface 12 at the edge of the external angle, and one layer of the substrate 2 is melt-bonded to the transition surface 12. When the substrate 2 is attached to the transition surface 12, the first laid substrate 2 gives way at the upper position of the embedded groove 21 due to melting, so that the previous substrate 2 is not easy to cover the other substrate 2 embedded in the embedded groove 21.
