Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a roof waterproof structure with good waterproof performance. Background Art

[0002] Building roofs are composed of a reinforced concrete structural layer, a leveling layer, a waterproof layer, an insulation layer, and a surface layer, all arranged in sequence. To ensure balanced air pressure in the sewer system, a vent pipe is embedded in the roof. However, the existing vent pipe waterproofing process involves extending the roof's waterproofing membrane to the outer surface of the vent pipe and bonding the waterproof pipe and vent pipe together with waterproof adhesive. Due to the vent pipe's long-term exposure to wind, sun, heat, and thermal expansion and contraction, gaps can form between the waterproof pipe and the vent pipe, leading to water seepage. To address these shortcomings, we propose a roof waterproofing structure with excellent waterproof properties. Utility Model Content

[0003] The purpose of the utility model is to provide a roof waterproof structure with good waterproof performance to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The waterproof layer is composed of a strip waterproof membrane laid on the leveling layer and a cylindrical waterproof membrane sleeved on the surface of the casing. A first circular waterproof membrane is fixedly installed on one end of the cylindrical waterproof membrane close to the strip waterproof membrane, and a second circular waterproof membrane is fixedly installed on the end of the cylindrical waterproof membrane away from the strip waterproof membrane.

[0007] Preferably, a sloped cement water-conducting layer is laid between the leveling layer and the casing.

[0008] Preferably, an assembly structure is provided between the air tube and the sleeve, the assembly structure includes an internal threaded barrel fixedly mounted on the inner wall of the sleeve, the surface of the air tube is provided with an external thread matching the internal threaded barrel, and a limiting ring is fixedly mounted on the surface of the air tube.

[0009] Preferably, the outer diameter of the limiting ring is adapted to the outer diameter of the sleeve.

[0010] Preferably, a thermal insulation layer and a surface layer are sequentially arranged above the waterproof layer.

[0011] Preferably, the surface layer is flush with the top end of the sleeve.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The present invention provides a waterproof layer, lays a strip waterproof membrane on top of the leveling layer, then cuts a circular hole in the strip waterproof membrane at the position of the sleeve for the sleeve to pass through, and then puts a cylindrical waterproof membrane on the sleeve. At this time, the first circular waterproof membrane is located above the strip waterproof membrane. The second circular waterproof membrane is placed on the inner wall of the sleeve, and then the thermal insulation layer and the surface layer are laid in sequence until the surface layer is flush with the top of the sleeve. Then, the vent pipe and the sleeve are assembled into one by using an assembly structure. Compared with the existing technology, the device uses the thermal insulation layer and the surface layer to ensure that the cylindrical waterproof membrane is firmly in contact with the sleeve. After the second circular waterproof membrane is placed in the sleeve, even if the cylindrical waterproof membrane and the sleeve are separated, since the second circular waterproof membrane is located in the sleeve with the opening facing downward, rainwater can be prevented from entering the cylindrical waterproof membrane along the second circular waterproof membrane, thereby improving the waterproof performance between the vent pipe and the roof.

[0014] 2. The utility model provides an assembly structure, and the external thread on the surface of the vent tube is screwed into the internal threaded barrel, so that the vent tube and the sleeve can be assembled into one. At this time, the lower end of the limit ring contacts the top of the sleeve to limit the vent tube. When the vent tube is damaged, the vent tube can be screwed out of the sleeve, so that the vent tube can be quickly replaced without changing the sleeve and the waterproof layer.

After the strip waterproof membrane 5 is laid on the leveling layer 4, a circular hole is cut out of the strip waterproof membrane 5 at the position of the casing 2 for the casing 2 to pass through. Then the cylindrical waterproof membrane 6 is put on the casing 2. At this time, the first circular waterproof membrane 7 is above the strip waterproof membrane 5, and the second circular waterproof membrane 8 is placed on the inner wall of the casing 2. Then the insulation layer 12 and the surface layer 13 are laid in sequence until the surface layer 13 is flush with the top of the casing 2, so that the cylindrical waterproof membrane 6 can be fixed to the surface of the casing 2.
