Technical Field
[0001] The utility model relates to a roof explosion relief device technology, and more specifically, the utility model relates to an LSIII roof explosion relief system. Background Art
[0002] Explosion-proof roofs are usually used on the top of industrial and civil plants, boiler rooms and dangerous goods warehouses. During the use of industrial and civil plants, boiler rooms and dangerous goods warehouses, dangers are prone to occur, such as gas leakage, steam leakage and fire, which will lead to high pressure in the sealed space, causing the plant to explode and bring personal danger to nearby residents.
[0003] As people's safety awareness becomes higher and higher, more and more people realize the importance of installing explosion relief devices on buildings with explosion hazards. Roof explosion relief devices open the roof through explosion relief accessories to release the pressure caused by the explosion, thereby minimizing the degree of damage. Existing roof explosion relief devices usually include explosion relief plates, steel purlins, explosion relief bolt devices, traction ropes and bolt assemblies, but the explosion relief bolt through holes reserved on the explosion relief plates are generally large in size, so waterproof gaskets need to be filled in the explosion relief bolt through holes, so the roof is prone to water leakage. In addition, explosion relief devices are generally disposable and difficult to recycle after use. Moreover, re-laying is time-consuming and labor-intensive, which greatly increases the cost of use. Therefore, it is necessary to improve and optimize them. Utility Model Content

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an LSIII roof explosion relief system, comprising a roof panel, a sliding support, a purlin, an explosion relief hinge, a lap strip and mastic, etc. The top of the roof panel is fixedly installed with a sliding support, the bottom of the roof panel is provided with a purlin, the upper flange surface of the purlin is fixedly connected to the bottom of the sliding support, and the roof panel is connected to the sliding support by a locking seam.
[0006] As an optimal technical solution of the utility model, the lower flange of the purlin is provided with an explosion-proof hinge, and a bolt and double-nut assembly is threadedly installed on the explosion-proof hinge, and the bolt and double-nut assembly passes through the purlin and the explosion-proof hinge. The left outer wall of the explosion-proof hinge is movably connected to the right outer wall of the overlapping back plate, and a bolt and double-nut assembly is threadedly installed on the overlapping back plate, and the bolt and double-nut assembly passes through the explosion-proof hinge and the overlapping back plate.
[0007] As a preferred technical solution of the utility model, explosion-relief nails are threadedly installed on the sliding support, and the explosion-relief nails penetrate the sliding support and the roof panel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0010] 1. The utility model is provided with a sliding support, which can effectively open the explosion vent quickly and release the internal accumulated pressure through the synergistic effect of the sliding support and the roof panel when the internal pressure of the building is too high, thereby avoiding or reducing the damage caused by the explosion. The upper flange surface of the purlin is fixedly connected to the bottom of the sliding support, which provides a solid support for the entire system, not only ensuring the stability of the explosion relief system during normal operation, but also withstanding a certain impact when an explosion occurs, reducing structural damage. Due to the modular design, the various components of the LSIII roof explosion relief system can be easily disassembled and installed, which greatly reduces the workload during maintenance and replacement and improves work efficiency.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] like Figures 1 to 3 As shown, the utility model provides an LSIII roof explosion relief system, a sliding support 3 is fixedly installed on the top of the roof panel 1, a purlin 2 is arranged at the bottom of the roof panel 1, the upper flange surface of the purlin 2 is fixedly connected to the bottom of the sliding support 3, and the roof panel 1 is connected to the sliding support 3 by locking seams.
[0018] By setting up the sliding support 3, when the internal pressure of the building is too high, the explosion vent can be quickly opened through the synergistic effect of the sliding support 3 and the roof panel 1 to release the internal accumulated pressure, thereby avoiding or reducing the damage caused by the explosion. The upper flange surface of the purlin 2 is fixedly connected to the bottom of the sliding support 3, providing a solid support for the entire system, which not only ensures the stability of the explosion relief system during normal operation, but also can withstand a certain impact when an explosion occurs, reducing structural damage. Due to the modular design, the various components of the LSIII roof explosion relief system can be easily disassembled and installed, which greatly reduces the workload during maintenance and replacement and improves work efficiency. Through the locking seam connection between the roof panel 1 and the sliding support 3, the system can effectively prevent moisture from penetrating and avoid potential safety hazards caused by leakage.
[0019] The roof panel 1 is installed on the upper flange surface of the purlin 2 through the sliding support 3. The roof panel 1 and the sliding support 3 are connected in the form of a lock seam. The sliding support 3 is installed on the upper flange surface of the purlin 2 through the explosion-proof nails 4. The top of the roof panel 1 is fixed together with the overlapping aluminum pressure strip 6, the overlapping glue 7 and the overlapping back plate 8 by a bolt double-nut assembly 9, and then a hole is punched at the lower flange position of the purlin 2. The explosion-proof hinge 5 is fixed by the bolt double-nut assembly 9 through the bolt hole pre-opened in the purlin 2, and the other end of the explosion-proof hinge 5 is fixedly connected to the overlapping back plate 8 by the bolt double-nut assembly 9.
[0020] Among them, the lower flange of the purlin 2 is provided with an explosion-proof hinge 5, and a bolt and double nut assembly 9 is threadedly installed on the explosion-proof hinge 5, and the bolt and double nut assembly 9 passes through the purlin 2 and the explosion-proof hinge 5. The left outer wall of the explosion-proof hinge 5 is movably connected with the right outer wall of the overlapping back plate 8, and a bolt and double nut assembly 9 is threadedly installed on the overlapping back plate 8, and the bolt and double nut assembly 9 passes through the explosion-proof hinge 5 and the overlapping back plate 8.
[0021] The design of the explosion-proof hinge 5 ensures that the structure can respond quickly when subjected to explosion pressure, thereby reducing damage to the overall structure. At the same time, the tightening effect of the bolt and double-nut assembly 9 ensures a stable connection between the purlin 2, the explosion-proof hinge 5 and the overlapping back plate 8 under normal working conditions, thereby improving the stability of the overall structure. Moreover, since the explosion-proof hinge 5 and the bolt and double-nut assembly 9 and other components are all designed to be detachable, these components can be easily replaced or repaired after an explosion occurs, so that the system can be quickly restored to use, thereby improving the reusability of the system.
[0022] The sliding support 3 and the roof panel 1 are firmly connected together by the explosion-proof nails 4 to form a stable overall structure, which enhances the structural stability of the entire system and enables it to remain stable when subjected to external loads or wind pressure and is not prone to displacement or deformation. The explosion-proof nails 4 are installed in a threaded manner, which makes the installation and disassembly process simple and quick, which not only improves the construction efficiency but also reduces the installation cost. Through the fixing effect of the explosion-proof nails 4, the gap between the roof panel 1 and the sliding support 3 is effectively filled, thereby improving the sealing and waterproof performance of the entire system, which helps to prevent moisture or other impurities from entering the system and ensure the long-term stable operation of the system.
[0023] Among them, an overlapping aluminum strip 6 is arranged on the top of the roof panel 1, an overlapping putty 7 is arranged on the bottom of the roof panel 1, and an overlapping backboard 8 is arranged on the bottom of the overlapping putty 7. Explosion-proof nails 4 are fixedly installed on the roof panel 1, and the explosion-proof nails 4 pass through the overlapping aluminum strip 6, the overlapping putty 7 and the overlapping backboard 8 in sequence.
[0024] By setting the overlapping aluminum strips 6 and the overlapping putty 7, the gaps between the roof panels 1 can be effectively filled, and the sealing of the roof can be improved, thereby preventing moisture or other impurities from entering. The addition of the overlapping backboard 8 further enhances the sealing effect and improves the overall waterproof performance. The design of the explosion-proof nails 4 enables the roof panel 1, the overlapping aluminum strips 6, the overlapping putty 7 and the overlapping backboard 8 to be firmly connected together to form a stable overall structure. This connection method not only enhances the system's wind and earthquake resistance, but also improves its stability under explosion impact and reduces the possibility of structural damage.
[0025] Through the design of the male edge 10 and the female edge 11, the roof panels 1 can be quickly and easily installed and connected. Through the mutual engagement of the male edge 10 and the female edge 11, the close fit between the roof panels can be ensured, thereby improving the integrity and stability of the entire roof, and improving the sealing and waterproof performance. The engagement structure of the male edge 10 and the female edge 11 can effectively prevent moisture or other impurities from entering the interior of the roof, thereby improving the sealing and waterproof performance of the roof. This design helps to reduce potential safety hazards caused by water leakage, ensures the safe use of the building, and enhances structural stability.
