Description

Technical Field

[0001] This utility model relates to the field of roof waterproofing technology, and more specifically, to a building roof waterproofing structure. Background Technology

[0002] The roof refers to the surface of a building's roof, and also the area between the ridge and the eaves. This part occupies a large area of ​​the roof, or in other words, the roof is the largest part of the roof. As an important component of the building's external envelope, the building roof is exposed to natural environments such as wind, sun, rain, and snow for a long time, and its waterproof performance directly affects the building's internal functionality and structural safety.

[0003] Traditional roof waterproofing often uses a single roll of waterproofing material or coating. This single roll of material or coating is directly exposed to the outside, allowing heat to be conducted into the room through the roof structure, resulting in poor heat insulation. Furthermore, the waterproofing material is prone to thermal expansion and contraction under temperature changes, leading to cracking or bulging of the roll of material and the formation of leakage channels. At the same time, during subsequent roof construction (such as the installation of solar water heaters or air conditioner outdoor units), construction tools can easily scratch the waterproofing layer, creating tiny cracks. Therefore, a new roof waterproofing structure is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waterproof structure for building roofs to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof roof structure, including a roof and a parapet wall. A leveling layer is provided on the top of the roof to provide a flat and solid base for the waterproof roll layer. A waterproof roll layer is provided on top of the leveling layer to ensure no leakage at the junction of the roof and the parapet wall. An anti-scratch coating is provided on top of the waterproof roll layer to resist damage from external forces such as construction tools and maintenance personnel. A first groove is provided on the top of one side of the parapet wall to accommodate the upturned portion of the waterproof roll layer. A fixing plate is provided on one side of the first groove to press the upturned portion of the waterproof roll layer into the first groove, preventing the waterproof roll layer from falling off. A protective strip is fixedly connected to the top of the fixing plate. The fixing plate and protective strip, located on one side of the first groove, can fix the top of the waterproof roll layer, preventing rainwater from entering between the waterproof roll layer and the leveling layer, further improving the waterproof strength. The top of the scratch-resistant coating is provided with a support frame, the bottom of which is fixedly connected to a support column. The top of the support frame is fixedly connected to a heat insulation board by rivets. The support column supports and fixes the support frame, which facilitates the fixing of the heat insulation board and improves stability. At the same time, the heat insulation board plays a role in heat insulation, which can effectively block the heat from the summer sun from entering the room, while protecting the waterproof roll layer and scratch-resistant coating below from direct sunlight and slowing down the aging of the waterproof layer.

[0006] Preferably, a drain pipe is provided in the middle of the leveling layer. One end of the drain pipe passes through the bottom of the parapet wall, and the other end of the drain pipe passes through the waterproof membrane and the anti-scratch coating and is fixedly connected with a fixing ring. The drain pipe can drain the liquid that passes through the gap between the insulation boards and is located on top of the anti-scratch coating.

[0007] Preferably, one end of the waterproof membrane extends to the inner side of the first groove, and one end of the scratch-resistant coating extends to the bottom of the inner cavity of the first groove. The top of the waterproof membrane is limited by the first groove to ensure that there is no leakage at the junction of the roof and the parapet wall.

[0008] Preferably, the end of the leveling layer is located on one side of the parapet wall, and the top of the end of the leveling layer is set as a slope. The waterproof roll and the scratch-resistant coating are attached to the wall of the leveling layer, which can seal the gap between the parapet wall and the roof and improve the waterproof effect.

[0009] Preferably, the protective strip is located inside the first groove and fits against the wall of the waterproof roll layer. The cross-sectional shape of the fixing plate is set to "L" shape. The protective strip presses and fixes the top of the waterproof roll layer, preventing liquid from entering between the waterproof roll layer and the leveling layer, thereby improving the waterproof fixing effect.

[0010] Preferably, bolts are inserted into the middle of both the fixing plate and the protective strip, one end of the bolts extends through the waterproof membrane and the scratch-resistant coating into the interior of the parapet wall, and one end of the bolts is fixedly connected with a screw head.

[0011] Preferably, a second groove is provided on one side of the fixing plate at the position corresponding to the bolt, the screw head is located in the middle of the second groove, and a sealing block is embedded in the opening of the second groove. The fixing plate and the protective strip are easily fixed by the bolt, and the screw head is limited by the second groove. The screw head is sealed by the sealing block to prevent the bolt from rusting.

[0012] Preferably, the heat insulation board is made of extruded polystyrene board with a thickness of 50-80mm. The top of the heat insulation board is provided with an aluminum foil reflective film, the top of the support frame is provided with a buffer pad, and the bottom of the support column is fixedly connected to the leveling layer by bolts through the board. The aluminum foil reflective film can effectively block the summer sun's heat from entering the room, improve the heat insulation effect, and at the same time protect the waterproof roll layer and scratch-resistant coating below from direct sunlight, and slow down the aging of the waterproof layer.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model firstly prevents rainwater from entering through the gap between the waterproof membrane and the parapet wall by setting a waterproof membrane, ensuring no leakage at the junction of the roof and the parapet wall. The heat insulation board and support column can separate the heat insulation board from the scratch-resistant coating. The heat insulation board plays a role in heat insulation, which can effectively block the heat of the summer sun from entering the room. At the same time, it protects the waterproof membrane and scratch-resistant coating below from direct sunlight, slows down the aging of the waterproof layer, and will not cause damage to the scratch-resistant coating and waterproof membrane during later construction, thus improving the service life. 2. This utility model also features a first groove for accommodating the upturned portion of the waterproof membrane. A fixing plate and a protective strip press the upturned portion of the waterproof membrane into the first groove to prevent it from falling off. A drain pipe allows liquid that passes through the gaps between the insulation boards and is located on top of the scratch-resistant coating to be discharged. The aluminum foil reflective film on top of the insulation board effectively blocks summer sunlight from entering the room, improving the heat insulation effect. At the same time, it protects the waterproof membrane and scratch-resistant coating below from direct sunlight and slows down the aging of the waterproof layer.

[0014] In summary, through the interaction of the above-mentioned multiple effects, the waterproofing and heat insulation effects can be improved, the waterproof membrane and scratch-resistant coating can be protected from direct sunlight, the aging of the waterproof layer can be slowed down, and damage can be avoided during later construction, thus extending the service life.
