Description

Technical Field

[0001] This utility model belongs to the field of waterproofing technology for smoke exhaust fan wall connections, and in particular relates to a construction waterproofing structure for smoke exhaust fan wall connections. Background Technology

[0002] Smoke exhaust fans need to be installed in wall penetrations. The waterproofing at the smoke exhaust fan's connection point is crucial for ensuring the building's waterproofing performance. Below are some key construction steps and technical points. Choosing the right waterproofing material is the first step in waterproofing. It is recommended to use waterproofing materials that are highly weather-resistant, elastic, and corrosion-resistant, such as polymer waterproofing materials or special waterproofing coatings. These materials can effectively resist harsh external environments and ensure long-term waterproofing.

[0003] Some exhaust fans have their grilles fixed to the wall surface with bolts. Then, waterproof material is used to fill and seal the space between the exhaust pipe and the wall penetration. Because the waterproof material is in direct contact with both the exhaust pipe and the wall penetration, and lacks its own support structure, it can deform or shift over time, affecting the sealing effect. Therefore, a new waterproofing structure is needed at the exhaust fan's connection to the wall. This structure could be reinforced with a framework between the exhaust pipe and the wall penetration, making the pipe installation more stable and providing support for the waterproof material filling. This improves the stability of the waterproofing and sealing, thus enhancing the overall waterproofing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof construction structure for the connection between the exhaust fan and the wall. By adding a skeleton structure between the exhaust pipe and the wall, the installation of the exhaust pipe in the wall becomes more stable, and the skeleton supports the filling of the waterproof material, thereby improving the stability of the waterproof material filling and sealing, and thus improving the waterproof sealing effect, so as to solve the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A waterproof construction structure for the connection of a smoke exhaust fan to a wall includes a cylinder: the surface of the cylinder is provided with a threaded surface, an internal threaded ring is threadedly connected to the surface of the threaded surface, a ring is rotatably connected to the front side of the internal threaded ring, the ring is fixedly connected to the surface of the cylinder, a wedge-shaped slide rail is slidably connected to the surface of the ring, a bar is provided on the surface of the wedge-shaped slide rail, a connecting block is rotatably connected between the ring and the bar through a rotating shaft, a bolt rod and a pressing block are provided above the wedge-shaped slide rail, a through-wall smoke exhaust pipe is fixedly connected to the inner wall of the cylinder, a grid plate is fixedly connected to the surface of the through-wall smoke exhaust pipe, and a waterproof adhesive layer is filled between the cylinder and the hole wall.

[0006] Preferably, the bottom end of the bolt rod passes through the extrusion block and is threadedly connected to the wedge-shaped slide rail, and the surface of the wedge-shaped slide rail is provided with a threaded hole that matches the bolt rod.

[0008] Preferably, an isolation pad is fitted on the surface of the second bolt rod, and both the second bolt rod and the bar are in contact with the isolation pad.

[0009] Preferably, the waterproof adhesive layer is a neutral silicone sealant layer.

[0010] The beneficial effects of this utility model are: 1. This utility model involves welding a cylinder to the surface of a through-wall exhaust pipe, then moving a wedge-shaped slide rail via a bar, which in turn moves an extrusion block outward and abuts against the wall of the hole. A waterproof adhesive layer is then filled between the cylinder and the wall of the hole, thus adding a skeleton structure between the exhaust pipe and the wall of the hole. This makes the installation of the exhaust pipe in the wall of the hole more stable, and the skeleton supports the filling of the waterproof material, thereby improving the stability of the waterproof material filling and sealing, and thus improving the waterproof sealing effect. 2. This utility model allows for the disassembly and assembly of the bar and the wedge-shaped slide rail through the setting of the bolt rod two, which facilitates the connection and fixation of the two during installation. The structure is simple and economical. 3. By setting up isolation pads, this utility model protects the bolt rod and the bar rod by separating them, avoiding deformation and damage when they are in direct contact and squeezed, thus ensuring the integrity of the components.

Detailed Implementation

[0013] In the following description, embodiments of the waterproof construction structure for the smoke exhaust fan connected to the wall according to the present invention will be described with reference to the accompanying drawings.

[0014] Example 1: Figure 1-3 This invention illustrates a waterproof construction structure for a smoke exhaust fan connected to a wall, comprising a cylinder 1. The cylinder 1 has a threaded surface 2, and an internally threaded ring 3 is threaded onto the surface of the threaded surface 2. A ring 4 is rotatably connected to the front side of the internally threaded ring 3. The ring 4 is fixedly connected to the surface of the cylinder 1. A wedge-shaped slide rail 5 is slidably connected to the surface of the ring 4. A bar 6 is provided on the surface of the wedge-shaped slide rail 5. A connecting block 8 is rotatably connected between the ring 4 and the bar 6 via a rotating shaft. A bolt rod 7 and a pressing block 9 are provided above the wedge-shaped slide rail 5. The bottom end of the bolt rod 7 passes through the pressing block 9 and is threadedly connected to the wedge-shaped slide rail 5. The surface of the wedge-shaped slide rail 5 has a connection point with the bolt rod 7. The matching threaded hole, through the setting of bolt rod 1 7, can stably connect the extrusion block 9 and the wedge slide rail 5. It is a detachable component, which is easy to replace during subsequent maintenance. Bolt rod 2 10 is provided through the surface of the bar rod 6. The end of bolt rod 2 10 passes through the bar rod 6 and is threadedly connected to the wedge slide rail 5. Through the setting of bolt rod 2 10, the bar rod 6 and the wedge slide rail 5 can be disassembled and assembled, which is convenient for connecting and fixing the two during installation. The structure is simple and economical. The inner wall of the cylinder 1 is fixedly connected to the through-wall exhaust pipe 12. The surface of the through-wall exhaust pipe 12 is fixedly connected to the grid plate 13. The cylinder 1 and the hole wall are filled with a waterproof adhesive layer 14.

[0015] Example 2: Figure 1-3 This invention illustrates a waterproof construction structure for a smoke exhaust fan connected to a wall, comprising a cylinder 1. The cylinder 1 has a threaded surface 2, and an internal threaded ring 3 is threadedly connected to the surface of the threaded surface 2. A ring 4 is rotatably connected to the front side of the internal threaded ring 3. The ring 4 is fixedly connected to the surface of the cylinder 1. A wedge-shaped slide rail 5 is slidably connected to the surface of the ring 4. A bar 6 is provided on the surface of the wedge-shaped slide rail 5. A connecting block 8 is rotatably connected between the ring 4 and the bar 6 via a rotating shaft. A bolt rod 7 and a pressing block 9 are provided above the wedge-shaped slide rail 5. The inner... A through-wall exhaust pipe 12 is fixedly connected to the wall, and a grid plate 13 is fixedly connected to the surface of the through-wall exhaust pipe 12. A waterproof adhesive layer 14 is filled between the cylinder 1 and the hole wall. An isolation pad 11 is fitted on the surface of the bolt rod 10. Both the bolt rod 10 and the strip rod 6 are in contact with the isolation pad 11. The isolation pad 11 is used to protect the bolt rod 10 and the strip rod 6, avoiding deformation and damage when they are in direct contact and squeezed, thus ensuring the integrity of the components. The waterproof adhesive layer 14 is a neutral silicone sealant layer.

[0016] Working principle: When using this utility model, the user welds the cylinder 1 to the surface of the through-wall exhaust pipe 12, then inserts the cylinder 1 and the through-wall exhaust pipe 12 into the wall hole. Next, the grid plate 13 is fixed to the wall with bolts. Then, the internal threaded ring 3 rotates on the surface of the threaded surface 2, causing the internal threaded ring 3 to drive the bar 6 to move horizontally through the ring 4 and the connecting block 8. During this process, the ring 4 and the internal threaded ring 3 rotate relative to each other. At the same time, under the guidance of the ring 4, the bar 6 drives the extrusion block 9 to move outward through the wedge-shaped slide rail 5 and abut against the hole wall. Then, a waterproof adhesive layer 14 is filled between the cylinder 1 and the hole wall, realizing the addition of a skeleton structure between the exhaust pipe and the hole wall. This makes the installation of the exhaust pipe in the hole wall more stable, and the skeleton supports the filling of the waterproof material, thereby improving the stability of the waterproof material filling and sealing, and thus improving the waterproof sealing effect.

[0017] In summary: The waterproof construction at the wall connection of the exhaust fan involves welding the cylinder 1 to the surface of the exhaust pipe 12 that passes through the wall. Then, the bar rod 6 drives the wedge-shaped slide rail 5 to move, which in turn drives the extrusion block 9 to move outward and abut against the wall. Finally, a waterproof adhesive layer 14 is filled between the cylinder 1 and the wall. This achieves the purpose of adding a skeleton structure between the exhaust pipe and the wall, making the installation of the exhaust pipe in the wall more stable. The skeleton also supports the filling of the waterproof material, thereby improving the stability of the waterproof material filling and sealing, and thus improving the waterproof sealing effect.
