Description

Technical Field

[0001] This utility model relates to the field of explosion relief wall technology, specifically to a lightweight explosion relief wall with anti-seepage and fireproof properties. Background Technology

[0002] In the field of industrial buildings, explosion relief walls, as an important safety protection structure, are widely used in places with explosion risks, such as chemical plants, pharmaceutical plants, and flour milling plants. Their main function is to release the explosion pressure in a timely manner through a properly designed structure during an explosion, thereby reducing damage to the building structure and personnel, and ensuring the safety of life and property.

[0003] Explosion-relief walls are mainly composed of a light steel keel frame, explosion-relief panels, rock wool, and other structures. The light steel keel frame is constructed from vertical keels, horizontal through-beams, and ground keels. Explosion-relief panels are installed on both sides of the keel frame and fixed with self-tapping screws. The splicing of the explosion-relief panels is a crucial step in construction. Ideally, the splices should be tight and seamless to ensure that pressure can be evenly transmitted and released during an explosion, while preventing a decrease in sound insulation performance and the intrusion of rainwater and moisture into the cavity through gaps, which would increase the thermal conductivity of insulation materials such as rock wool. However, in actual construction, due to various factors, gaps of varying degrees often appear when splicing explosion-relief panels. Furthermore, traditional explosion-relief walls exposed for extended periods are susceptible to structural damage due to moisture erosion, reducing the wall's service life. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a lightweight explosion relief wall with impermeability and fireproof performance. This solves the problems mentioned in the background art, such as gaps at the joints of adjacent explosion relief panels, which lead to uneven pressure transmission and release during an explosion, as well as reduced sound insulation performance and increased thermal conductivity.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a lightweight explosion relief wall with anti-seepage and fireproof performance, comprising a lightweight keel frame and multiple explosion relief plates located on both sides of the lightweight keel frame. The lightweight keel frame includes a ground frame, vertical keels, through-core keels, and square tubes. Multiple vertical keels are installed between the ground frame and the square tubes. Multiple through-core grooves are opened on each vertical keel. The through-core keels are set in the through-core grooves. The through-core keels and vertical keels form multiple closed chambers, which are filled with rock wool. A first snap-fit ​​plate and a second snap-fit ​​plate are respectively provided on the opposite surfaces of two adjacent explosion relief plates. The first snap-fit ​​plate and the second snap-fit ​​plate are spliced ​​together by embedding.

[0006] Furthermore, the raw materials of the explosion relief plate are all mixed with cenosphere powder filler, and the outer layer of the explosion relief plate is all sprayed with nano-silicate-based waterproof coating.

[0007] Furthermore, the first card slot is provided on the first card slot, and a first card block is provided on one side of the first card slot. The second card slot is provided with a second card block and a second card slot that are adapted to the first card slot and the first card block, respectively.

[0008] Furthermore, both the first and second card slots are equipped with sealing gaskets.

[0009] Furthermore, both ends of the explosion relief plate are provided with limiting components, and limiting holes are opened on both sides of the base and the square tube.

[0010] Furthermore, the explosion vent plate is connected to the vertical keel, the ground keel, and the square tube by multiple self-tapping screws.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model interlocks two adjacent explosion relief plates together, which can improve the sealing performance of the connection, prevent the pressure from being unevenly transmitted and released during an explosion, and prevent the problems of reduced sound insulation performance and increased thermal conductivity; the addition of cenosphere powder filler to the explosion relief plate raw material can improve the fire resistance of the explosion relief plate; the outer layer is sprayed with nano-silicate-based waterproof coating to form a waterproof protective layer, which effectively solves the problem of water seepage and corrosion caused by long-term exposure due to the lack of an effective protective layer on the outer interface of the traditional explosion relief wall, thus extending the service life of the wall.

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] This utility model provides a lightweight explosion-proof wall with anti-seepage and fireproof properties, including a lightweight keel frame and multiple explosion-proof panels 1 located on both sides of the lightweight keel frame. The lightweight keel frame includes a ground keel 2, vertical keels 3, through-core keels 4, and square tubes 5. Multiple vertical keels 3 are installed between the ground keels 2 and the square tubes 5. Multiple through-core grooves are opened on each vertical keel 3. The through-core keels 4 are placed in the through-core grooves. The through-core keels 4 and the vertical keels 3 form multiple closed chambers. The chambers are filled with rock wool 7. The fireproof and heat-insulating properties of rock wool 7 are used to improve the performance of the wall. A first snap-fit ​​plate 8 and a second snap-fit ​​plate 9 are respectively provided on the opposite surfaces of two adjacent explosion-proof panels 1. The first snap-fit ​​plate 8 and the second snap-fit ​​plate 9 are spliced ​​together by embedding. The first snap-fit ​​plate 8 and the second snap-fit ​​plate 9 are integrated with the corresponding explosion-proof panel 1, which improves the sealing performance of the connection between two adjacent explosion-proof panels and reduces the generation of gaps.

[0018] like Figure 1-3 As shown, the ground joists 2 are fixed to the ground of the building using expansion bolts. Multiple vertical joists 3 are vertically installed on the ground joists 2, with the spacing between them determined according to the design load. Through-holes are arranged horizontally along the height of the vertical joists 3 to fix the through-hole 4. The through-hole 4 is inserted into the through-holes on the same horizontal plane of two adjacent vertical joists 3 and fixed in the through-holes using clips. After the vertical joists 3 are installed, multiple square tubes 5 parallel to the through-hole 4 are fixedly installed on the top of the multiple vertical joists 3. The spacing between two adjacent square tubes 5 is... Several vertical keels 3 are installed in the middle, and then the explosion relief plate 1 on one side of the keel frame is installed. When installing the explosion relief plate 1, the first snap-fit ​​plate 8 and the second snap-fit ​​plate 9 on one side of the two explosion relief plates 1 are fitted together, and then rock wool 7 is filled. Finally, the explosion relief plate 1 on the other side of the keel is installed in the same way as the explosion relief plate 1 on one side of the keel. Compared with the traditional splicing method, it can significantly improve the sealing performance of the two, reduce the generation of gaps, prevent the pressure from not being evenly transmitted and released when an explosion occurs, and prevent the problems of reduced sound insulation performance and increased thermal conductivity.

[0019] The explosion relief plate 1 is made of bleaching powder filler mixed in its raw materials, and the outer layer of the explosion relief plate 1 is coated with nano-silicate-based waterproof coating.

[0020] like Figure 1 As shown, the outer layer of the explosion relief plate 1 is uniformly sprayed with nano-silicate-based waterproof coating to form a waterproof protective layer, which effectively solves the problem of water seepage and corrosion caused by long-term exposure due to the lack of an effective protective layer on the outer interface of the traditional explosion relief wall; the explosion relief plate is filled with cenosphere powder filler, which can improve the fire resistance of the explosion relief plate.

[0021] The first card slot 9 is provided on the first card slot 7, and a first card block 10 is provided on one side of the first card slot 9. The second card slot 8 is provided with a second card block 11 and a second card slot 12 that are adapted to the first card slot 9 and the first card block 10, respectively.

[0022] like Figure 1 and 2 As shown, when splicing two adjacent explosion relief plates 1, one of the explosion relief plates 1 is first fixed to the keel frame, so that the first slot 9 on the first snap-fit ​​plate 7 of the explosion relief plate 1 faces outward. Then, the other explosion relief plate 1 is installed, and the second snap-fit ​​block 11 on the second snap-fit ​​plate 8 of the other explosion relief plate 1 falls into the first slot 9, and the first snap-fit ​​block 10 falls into the second slot 12, forming a maze path, which can greatly reduce the entry of rainwater and moisture.

[0023] Both the first card slot 9 and the second card slot 12 have sealing gaskets fixed inside by adhesive.

[0024] like Figure 1 As shown, the sealing effect can be increased by using a sealing gasket.

[0025] The explosion relief plate 1 has a limiting member 13 on one side at both ends. The limiting member 13 is integrated with the explosion relief plate 1. The ground frame 2 and the square tube 5 have limiting holes 14 on both sides. The limiting holes 14 on both sides of the ground frame 2 are adapted to the limiting member 13. The limiting holes 14 on both sides of the square tube 5 can accommodate two limiting members 13.

[0026] like Figure 1 As shown, in order to facilitate the installation of the explosion relief plate 1, the explosion relief plate 1 is initially positioned, and the limiting parts 13 at both ends of the explosion relief plate 1 are inserted into the corresponding limiting holes 14 respectively to restrict the explosion relief plate 1 from moving up and down. At the same time, it can also prevent rainwater and moisture from entering from the gap between the base plate 2 or the square tube and the explosion relief plate 1, further increasing the sealing effect.

[0027] The explosion venting plate 1 is connected to the vertical keel 3, the explosion venting plate 1 is connected to the ground keel 2, and the explosion venting plate 1 is connected to the square tube 5 by multiple self-tapping screws 15.

[0028] like Figure 1 As shown, the explosion relief plate 1 is laid on one side of the keel frame, so that the explosion relief plate 1 covers the ground keel 2, vertical keel 3, through keel 4 and square tube 5. The explosion relief plate 1 is fixed to the vertical keel 3, ground keel 2 and square tube 5 by multiple self-tapping screws 15, and the self-tapping screws 15 are evenly distributed.

[0029] Construction of the keel frame: Fix the ground joists 2 to the ground of the building using expansion bolts. Install multiple vertical keels 3 vertically and equidistantly on the ground joists 2. The spacing of the vertical keels 3 is determined according to the design load. Fix square tubes 5 to the top of the multiple vertical keels 3. After the square tubes 5 are installed, install through-ribs 4 in the through-groove of the vertical keels 3. After the through-ribs 4 are inserted into the through-groove, use clips to fix the through-ribs 4 in the through-groove. According to the height requirements, fix several vertical keels 3 to the top of the square tubes 5. Repeat this process to complete the construction of the keel frame.

[0030] Explosion relief plate installation: Lay explosion relief plate 1 on one side of the keel frame. Specifically, insert the limiting pieces 13 at the upper and lower ends of explosion relief plate 1 into the limiting holes 14 of the ground joists 2 and square tubes 5 respectively, so that explosion relief plate 1 does not move up and down. Then install the second explosion relief plate 1 in sequence. When installing the second explosion relief plate 1, while inserting the limiting pieces 13 at the upper and lower ends of the second explosion relief plate 1 into the limiting holes 14, embed the second snap-fit ​​plate 8 on one side of the second explosion relief plate 1 and the first snap-fit ​​plate 7 on one side of the first explosion relief plate 1 together, and use self-tapping screws 15 to fix the explosion relief plate 1 to the corresponding ground joists 2, vertical keels 3 and square tubes 5. Then fill with rock wool 6. Finally, install the explosion relief plate 1 on the other side in the same way as laying the explosion relief plate 1 on one side of the keel frame.
