Technical Field
[0001] The utility model relates to the technical field of building waterproofing, in particular to a waterproof structure for a building roof. Background Technique
[0002] Waterproofing is mostly used in roofs, underground buildings, the underground parts of buildings, and inner rooms and water storage structures that need waterproofing. According to the different measures and means taken, it is divided into two categories: material waterproofing and structural waterproofing. Material waterproofing relies on building materials to block the passage of water to achieve the purpose of waterproofing or increase the anti-leakage ability, such as roll waterproofing, coating waterproofing, rigid waterproofing of concrete and cement mortar, and waterproofing with clay and lime soil. Structural waterproofing adopts appropriate structural forms to block the passage of water to achieve the purpose of waterproofing, such as water stops and cavity structures. However, cracks are likely to occur at the joint between the parapet wall and the roof of existing buildings during long-term use, causing rainwater to seep into the room, and the drainage outlets at the upper end of the roof are easily blocked by foreign objects and cannot drain rainwater from the roof in time. Therefore, technicians in this field have provided a waterproof structure for a building roof to solve the problems raised in the above background technique. Content of the Utility Model
[0003] The purpose of the utility model is to provide a waterproof structure for a building roof to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A waterproof structure for a building roof includes a roof wall, a parapet wall is fixedly connected to the upper end of the roof wall, a waterproof device is threadedly connected between the roof wall and the parapet wall, a drainage groove is opened on the upper surface of the roof wall, a drainage installation base is fixedly connected to the inside of the drainage groove, a floating ball moving pipe is threadedly connected to the outside of the drainage installation base, a foreign object blocking block is fixedly connected to the upper end of the floating ball moving pipe, an observation hole is opened in the middle of the foreign object blocking block, and a floating ball is placed on the upper side of the drainage installation base.

[0008] Preferably, a waterproof leveling layer is applied to the surface of the upper end of the roof wall near the parapet wall. A waterproof bonding layer is applied between the waterproof device, the waterproof leveling layer and the parapet wall. Waterproof sealant is filled between the upper clamping block and the first lower clamping block groove, and between the lower clamping block and the second lower clamping block groove. A fixing bolt is threadedly connected to the inner end of the bolt groove. A rainwater guiding slope is provided at one end of the waterproof device away from the parapet wall.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0010] 1. First, apply a waterproof leveling layer to the position on the upper end of the roof wall where the waterproof device needs to be installed, so that the waterproof device fits perfectly with the roof wall during installation. The waterproof leveling layer can fill the uneven or sunken parts on the wall surface, ensuring that the waterproof device can fit perfectly with the roof wall during installation, which is beneficial to the fixation and adhesion of the waterproof device, enhancing the adhesion between the waterproof device and the wall surface. Then, apply a waterproof bonding layer to the places where the waterproof device, the waterproof leveling layer and the parapet wall need to be installed. The waterproof bonding layer can enhance the bonding force between each component and the base material, making the overall structure more firm and stable, reducing the risk of loosening or falling off, and enhancing the sealing and waterproof performance between each component, reducing the possibility of water penetration, thereby improving the waterproof effect of the overall structure. Align the positioning block of the waterproof device with the upper clamping block groove for installation, insert the lower clamping block into the second lower clamping block groove, and insert the upper clamping block into the upper clamping block groove. Finally, fill the second lower clamping block groove and the upper clamping block groove with waterproof sealant. Using waterproof sealant to fill the clamping block groove can effectively ensure the sealing performance and prevent water from seeping in from the joint, thereby protecting the building structure from water damage. Install a fixing bolt in the bolt groove to further fix the waterproof device. The area between the roof wall and the parapet wall is a part of the building structure that is easily eroded by water. Strengthening the waterproofing through the waterproof device can effectively enhance the waterproof performance of the connection, reduce the possibility of water penetration, and protect the building structure from water damage. Moreover, the waterproof device can also enhance the stability of the wall structure, reinforce the connection between the roof wall and the parapet wall, make the wall structure more firm, and reduce the risk of wall loosening or cracking caused by water erosion.
[0011] 2. When it rains, rainwater flows through the rainwater guiding slope into the drainage trough at the upper end of the roof wall. Then, the rainwater flows from the drainage trough through the drainage holes into the floating ball moving pipe. The rainwater floats the floating ball in the floating ball moving pipe. The rainwater flows from the drainage installation base into the drainage channel, and then from the drainage channel to the drainage water guiding part. The drainage water guiding part discharges the rainwater without flowing onto the wall. The drainage water guiding part bracket fixedly supports the drainage water guiding part. The foreign object blocking block and the drainage holes can filter out most foreign objects to prevent the drainage trough from being blocked by foreign objects. When it does not rain, the floating ball protects the drainage installation base to prevent foreign objects from blocking. When it rains, the floating ball floats up. The situation of the floating ball can be observed through the observation hole. When there are foreign objects in the floating ball moving pipe, the floating ball moving pipe can be rotated and removed from the drainage installation base to clean the floating ball moving pipe.

[0018] The working principle of the utility model is as follows: First, apply a waterproof leveling layer to the position on the upper end of the roof wall where the waterproof device needs to be installed, so that the waterproof device fits perfectly with the roof wall during installation. The waterproof leveling layer can fill the uneven or sunken parts on the wall surface, ensuring that the waterproof device can fit completely with the roof wall during installation, which is beneficial to the fixation and adhesion of the waterproof device, enhancing the adhesion between the waterproof device and the wall. Then, apply a waterproof bonding layer to the waterproof device, the waterproof leveling layer, and the places on the parapet wall where installation is required. The waterproof bonding layer can enhance the bonding force between each component and the base material, making the overall structure more firm and stable, reducing the risk of loosening or falling off, and enhancing the sealing and waterproof performance between components, reducing the possibility of water penetration, thereby improving the waterproof effect of the overall structure. Align the positioning block of the waterproof device with the upper block slot for installation, insert the lower block into the lower block slot two, and insert the upper block into the upper block slot. Finally, pour waterproof sealant into the lower block slot two and the upper block slot. Using waterproof sealant to fill the block slot can effectively ensure the sealing performance and prevent water from seeping in through the joints, thereby protecting the building structure from water damage. Install fixing bolts in the bolt slots to further fix the waterproof device. The area between the roof wall and the parapet wall is a part of the building structure that is vulnerable to water erosion. Strengthening the waterproofing through the waterproof device can effectively enhance the waterproof performance of the connection, reduce the possibility of water penetration, and protect the building structure from water damage. The waterproof device can also enhance the stability of the wall structure, reinforce the connection between the roof wall and the parapet wall, making the wall structure more firm, and reducing the risk of wall loosening or cracking caused by water erosion. When it rains, rainwater flows through the rainwater guiding slope into the drainage trough at the upper end of the roof wall, and then flows from the drainage trough into the floating ball moving pipe through the drainage holes. The rainwater floats the floating ball in the floating ball moving pipe. The rainwater flows from the drainage installation base into the drainage channel, and then flows from the drainage channel onto the drainage water guiding part. The drainage water guiding part discharges the rainwater without flowing onto the wall surface. The drainage water guiding part support fixes and supports the drainage water guiding part. The foreign object blocking block and the drainage holes can filter out most foreign objects to prevent foreign objects from blocking the drainage trough. When it is not raining, the floating ball protects the drainage installation base from foreign object blockage. When it rains, the floating ball floats up, and the situation of the floating ball can be observed through the observation hole. When there are foreign objects in the floating ball moving pipe, the floating ball moving pipe can be rotated and removed from the drainage installation base to clean the floating ball moving pipe.
