Description

Technical Field

[0001] The utility model provides an explosion relief wall which can be conveniently disassembled and belongs to the technical field of safety precautions for buildings. Background Art

[0002] Explosion-proof walls, also known as explosion decompression panels or explosion-proof walls, are a type of safety facility designed to protect buildings and the people inside them from the effects of explosion accidents. Their working principle is to allow the explosion pressure to be quickly released to a predetermined safe area when an explosion occurs, thereby reducing damage to the main structure and protecting the surrounding environment and personnel safety. Explosion-proof walls are usually made of lightweight materials such as high-strength composite panels, metal mesh materials or special pressure-relief diaphragms. These materials can rupture or deform when the explosion pressure reaches a certain threshold, forming a pressure relief port, guiding the high-pressure gas and flames generated by the explosion to be released to the outside through this opening, while reducing the reflection and propagation of the explosion shock wave.

[0003] At present, when installing explosion-proof walls, a hole is reserved for installation on the wall, and then a hollow rectangular tube is installed in the hole, which is connected by bolts or welded into an integral structure as a keel structure. Then rock wool is filled between the keels, and finally the explosion-proof plate is fixed to the keel with bolts. However, if the explosion-proof wall is damaged to a certain extent in an explosion incident, it needs to be replaced to ensure that it continues to function. The integrated keel structure requires replacement of a larger area or even the entire explosion-proof wall. Over time, the material may age due to environmental factors, affecting its performance and also requiring replacement. Replacing the explosion-proof plate may cause thread slippage in the threaded holes on the original rectangular tube. Utility Model Content

[0006] As an improvement, the front and back plates are made of light and fragile materials;

[0007] As an improvement, the telescopic rod includes a sleeve arranged at the middle of the surface of the front plate and the back plate close to each other, a threaded rod threadedly connected to the two sleeves and one end of which passes through the middle of the front plate, and a cross groove is provided in the middle of one end of the threaded rod close to the front plate;

[0008] As an improvement, one end of the threaded rod provided with a cross groove does not extend beyond the end surface of the positive plate;

[0009] As an improvement, the sound-absorbing cotton is rock wool.

[0010] Beneficial effects of the utility model:

[0011] By arranging the telescopic rod, baffle plate 1, baffle plate 2, baffle plate 3 and the slot, any two adjacent explosion venting panels can be connected to each other and can be installed in the installation hole of the wall. When replacement is needed, the threaded rod of the telescopic rod is unscrewed, and then the explosion venting panel can be removed by tilting the explosion venting panel.

[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] according to Figure 1—3: The utility model provides an explosion-proof wall which can be conveniently disassembled: it comprises an explosion-proof plate 1 and a wall 2; the explosion-proof plate 1 comprises a front plate 3 arranged at one end of the wall 2 and a back plate 4 arranged at one end of the wall 2, the distance between the front plate 3 and the back plate 4 is controlled by a telescopic rod 5 which can be controlled from the outside, a baffle 1 6 is arranged on one side and the rear of the middle part of the lower end of the explosion-proof plate 1, a baffle 2 7 is arranged on the other side and the front of the upper end, any two adjacent explosion-proof plates 1 are positioned by the baffle 1 6 and the baffle 2 7, an installation hole for installing the explosion-proof wall is arranged on the wall 2, one side and the installation hole The lower end is provided with a baffle plate 3 8 which fits one side of the baffle plate 1 6, and the other side and the upper end are provided with a slot 9 which fits one side of the baffle plate 2 7. Sound-absorbing cotton is filled between the front plate 3 and the back plate 4. The front plate 3 and the back plate 4 are made of lightweight and fragile materials, and the sound-absorbing cotton is rock wool. By arranging the telescopic rod 5, the baffle plate 1 6, the baffle plate 2 7, the baffle plate 3 8, and the slot 9, any two adjacent explosion-proof panels 1 can be connected to each other and can be installed in the installation hole of the wall 2. When replacement is required, the threaded rod 11 of the telescopic rod 5 is unscrewed, and then the explosion-proof panel 1 can be removed by tilting the explosion-proof panel 1.
