Description

Technical Field

[0001] This invention relates to the field of petrochemical building technology, specifically to a petrochemical explosion-proof structure and its manufacturing method. Background Technology

[0002] An blast-resistant structure is a structure in which the horizontal load is borne by blast-resistant walls and blast-resistant roof panels, and the vertical load is borne by internal frame components.

[0003] Currently, blast-resistant structures in the petrochemical industry are single-layer structures. However, the "Design Specifications for Blast-Resistant Structures in Petrochemical Buildings" (GB / T 50779-2022) clearly stipulates that when the peak incident overpressure of the blast shock wave is greater than 6.9 kPa but less than 21.0 kPa, the number of layers can be two. However, the composition of each component in the current two-layer blast-resistant structure system is still unclear. In existing blast-resistant structures, the blast-resistant roof panel and the roof beam of the inner frame assembly are weakly connected. The blast-resistant roof panel and the roof beam of the inner frame assembly are in direct contact and connected by structural steel reinforcement. This weak connection also transfers some of the horizontal blast load to the inner frame assembly. As the size of the blast-resistant building increases, the horizontal blast load borne by the inner frame assembly will increase, easily leading to excessive horizontal blast load on the inner frame assembly under blast conditions, potentially causing damage. Summary of the Invention

[0004] (I) This invention provides a petrochemical explosion-proof structure and its manufacturing method, which alleviates the technical problem in the prior art where the internal frame components bear excessive horizontal explosion loads, leading to damage.

The lower part of the sliding panel is also provided with a sliding pad, which is slidably connected to the sliding panel. The side of the sliding pad away from the sliding panel is bonded to the lower fixing plate.

[0015] Furthermore, a first deformation component is provided between the explosion-proof inner wall or the explosion-proof outer wall and the floor slab. The first deformation component includes a pad plate, a middle cover plate and a side cover plate.

[0016] The pad is bolted to the floor slab by anchor bolts. One end of the middle cover plate is bolted to the explosion-proof outer ring or the explosion-proof inner wall by anchor bolts, and the other end is laid flat on the upper surface of the pad. One end of the side cover plate is bolted to the floor slab by anchor bolts, and the other end is laid flat on the upper surface of the middle cover plate. The middle cover plate can slide between the pad and the side cover plate.

[0017] Furthermore, the first deformable component is also provided with an elastic adhesive strip, which is laid on the upper surface of the middle cover plate, and the upper top surface of the elastic adhesive strip is flush with the upper top surface of the side cover plate.

[0018] Furthermore, a sealing plate is provided between the frame column and the blast-resistant outer wall or the blast-resistant inner wall.

[0019] Furthermore, the load-bearing device includes a pile cap and engineering piles;

[0020] The support platform is used to connect the blast-resistant outer wall, the blast-resistant inner wall, or the longitudinal frame column, and the support platform is connected to the blast-resistant outer wall, the blast-resistant inner wall, or the longitudinal frame column by hinges.

[0021] The engineering piles are embedded in the lower end of the foundation, and the number of engineering piles corresponds to the number of blast-resistant outer walls, blast-resistant inner walls and longitudinal frame columns connected to the foundation.

[0048] like Figures 1 to 8 As shown, the present invention provides a petrochemical explosion-proof structure, including an explosion-proof wall, an inner frame assembly, a roof sliding assembly 3, and a load-bearing device; the inner frame assembly is connected to the inner wall of the explosion-proof wall, and the roof sliding assembly 3 is provided between the outer side of the top of the inner frame assembly and the explosion-proof wall, the roof sliding assembly 3 being used to drive the inner frame assembly and the explosion-proof wall to form a horizontal displacement; the load-bearing device is located below the explosion-proof wall and the inner frame assembly, and is hinged to the explosion-proof wall and the inner frame assembly.

[0049] In this embodiment, the blast-resistant structure includes a blast-resistant wall, an inner frame assembly, a roof sliding assembly 3, and a load-bearing device. The inner frame assembly is connected to the inner wall of the blast-resistant wall. The roof sliding assembly 3 is provided between the outer side of the top of the inner frame assembly and the blast-resistant wall. The roof sliding assembly 3 is used to drive the inner frame assembly and the blast-resistant wall to form a horizontal displacement. By setting the roof sliding assembly 3, the inner frame assembly can avoid bearing horizontal explosive loads in the event of an explosion, thereby further ensuring that it will not be damaged by the explosion. The load-bearing device is located below the blast-resistant wall and the inner frame assembly and is hinged to the blast-resistant wall and the inner frame assembly, improving the safety and applicability of the blast-resistant building. In both explosive and non-explosive conditions, the blast-resistant wall bears the horizontal load, while the inner frame assembly only bears the vertical load. At the same time, in the case of an extremely long blast-resistant building, the blast-resistant wall provides sufficient planar stiffness to resist the explosive impact load, thereby ensuring the safety and applicability of the blast-resistant structure.

[0050] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the blast-resistant wall includes an blast-resistant outer wall 101, an blast-resistant inner wall 102, and an blast-resistant roof panel 103; both ends of the blast-resistant roof panel 103 are connected to the blast-resistant outer wall 101, the center of the blast-resistant roof panel 103 is connected to the blast-resistant inner wall 102, and the side walls of the blast-resistant outer wall 101, the blast-resistant inner wall 102, and the blast-resistant roof panel 103 are connected to the inner frame components.

[0051] In this embodiment, the blast-resistant wall includes a blast-resistant outer wall 101, a blast-resistant inner wall 102, and a blast-resistant roof panel 103. Both ends of the blast-resistant roof panel 103 are connected to the blast-resistant outer wall 101, and the center of the blast-resistant roof panel 103 is connected to the blast-resistant inner wall 102. The side walls of the blast-resistant outer wall 101, the blast-resistant inner wall 102, and the blast-resistant roof panel 103 are respectively connected to the inner frame assembly. Preferably, the blast-resistant inner wall has a pre-reserved door opening 1021, and a vestibule 1022 is provided on one side of the door opening 1021. The blast-resistant inner wall only has a pre-reserved door opening 1021 without a safety door; the door is located on the vestibule 1022, and the vestibule 1022 wall is a masonry structure. This design ensures that the blast-resistant inner wall 102 allows normal passage while increasing its thermal insulation effect.

[0052] By setting up the blast-resistant inner wall 102, in the case of an ultra-long blast-resistant building, the blast-resistant inner wall can be used to limit the length-to-width ratio between the floor and the blast-resistant roof panels to no more than 2:1. This ensures that the floor and roof panels of the blast-resistant building have sufficient planar stiffness to resist the explosive impact load, thereby ensuring the safety and applicability of the blast-resistant structure used in petrochemical buildings.

[0053] All the longitudinal reinforcing bars in the upper and lower layers of the blast-resistant roof panel are anchored into the blast-resistant exterior wall and blast-resistant interior wall. Furthermore, the blast-resistant exterior wall and blast-resistant interior wall are connected to the blast-resistant roof panel by cast-in-place reinforced concrete, thus forming a rigid connection between the blast-resistant exterior wall, blast-resistant interior wall, and blast-resistant roof panel.

[0054] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the inner frame is set to two layers. The inner frame assembly includes several sets of frame columns 201 and floor slabs 202. Each set of frame columns 201 includes horizontal frame columns 201 and vertical frame columns 201. At least three frame columns 201 are arranged at intervals. Two horizontal frame columns 201 are arranged at intervals downward along the top of the three vertical frame columns 201, dividing the inner frame assembly into two layers and perpendicularly connected to the vertical frame columns 201. The floor slabs 202 are laid on the horizontal frame columns 201 that are away from the top of the vertical frame columns 201.

[0055] In this embodiment, the inner frame assembly includes several sets of frame columns 201 and floor panels 202. Each set of frame columns 201 includes transverse frame columns 201 and longitudinal frame columns 201. At least three frame columns 201 are arranged at intervals. Two transverse frame columns 201 are arranged at intervals downward along the top of the three longitudinal frame columns 201 and are perpendicularly connected to the longitudinal frame columns 201. The floor panels 202 are laid on the transverse frame columns 201 that are away from the top of the longitudinal frame columns 201.

[0056] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the inner frame assembly also includes roof beams 203 and floor beams 204. Several roof beams 203 are spaced below the floor slab 202 and are connected to the outer wall of the bottom surface of the floor slab 202. Several floor beams 204 are spaced inside the top of the inner frame structure and are connected to the inner wall of the top of the inner frame structure.

[0057] In this embodiment, the inner frame assembly also includes roof beams 203 and floor beams 204. Several roof beams 203 are spaced apart below the floor slab 202 and are connected to the outer wall of the bottom surface of the floor slab 202. Several floor beams 204 are spaced apart on the inner side of the top of the inner frame structure and are connected to the inner wall of the top of the inner frame structure.

[0058] The roof sliding component 3 is typically installed along the roof beam 203, and the gap between the explosion-proof roof panel and the roof beam 203 is 10-20mm. The frame column 201, floor slab 202, roof beam 203 and floor beam 204 are all connected by cast-in-place reinforced concrete.

[0059] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2As shown, the roof sliding assembly 3 includes an upper fixed plate 301, a lower fixed plate 302, a sliding panel 303, and a sliding pad 304. The upper fixed plate 301 is bolted to the explosion-proof roof panel 103 by anchor bolts, and the lower fixed plate 302 is bolted to the roof beam 203 by anchor bolts. The sliding panel 303 is located between the upper fixed plate 301 and the lower fixed plate 302 and is bolted to the upper fixed plate 301 by anchor bolts. A sliding pad 304 is also provided at the lower part of the sliding panel 303. The sliding pad 304 is slidably connected to the sliding panel 303, and the side of the sliding pad 304 away from the sliding panel 303 is bonded to the lower fixed plate 302.

[0060] In this embodiment, the roof sliding assembly 3 includes an upper fixing plate 301, a lower fixing plate 302, a sliding panel 303, and a sliding pad 304. Preferably, the upper fixing plate 301 is made of ordinary steel plate, and the lower fixing plate 302 is made of channel steel plate. The upper fixing plate 301 is bolted to the explosion-proof roof panel 103 by anchor bolts, and the lower fixing plate 302 is bolted to the roof beam 203 by anchor bolts. The sliding panel 303 is made of mirror stainless steel and is located between the upper fixing plate 301 and the lower fixing plate 302. It is bolted to the upper fixing plate 301 by anchor bolts. The lower part of the sliding panel 303 is also provided with a sliding pad 304. The sliding pad 304 is slidably connected to the sliding panel 303. The sliding pad 304 is made of polytetrafluoroethylene plate or modified ultra-high molecular weight polyethylene plate and is connected to the lower fixing plate 302 by adhesive bonding. The above configuration allows the sliding panel 303 to slide between the upper fixed plate 301 and the lower fixed plate 302, thus preventing the inner frame assembly from bearing horizontal explosive loads in the event of an explosion, thereby further ensuring that it will not be damaged by the explosion.

[0061] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, a deformation component 5 is provided between the explosion-proof inner wall 102 or the explosion-proof outer wall 101 and the floor slab 202. The deformation component 5 includes a pad 501, a middle cover plate 502 and a side cover plate 503. The pad 501 is bolted to the floor slab 202 by anchor bolts. One end of the middle cover plate 502 is bolted to the explosion-proof outer ring or the explosion-proof inner wall 102 by anchor bolts, and the other end is laid flat on the upper surface of the pad 501. One end of the side cover plate 503 is bolted to the floor slab 202 by anchor bolts, and the other end is laid flat on the upper surface of the middle cover plate 502. The middle cover plate 502 can slide between the pad 501 and the side cover plate 503.

[0062] In this embodiment, a deformation component 5 is provided between the explosion-proof inner wall 102 or the explosion-proof outer wall 101 and the floor slab 202. The deformation component 5 includes a pad 501, a middle cover plate 502, and a side cover plate 503. Optionally, the pad 501 is made of steel plate structure, and the thickness of the middle cover plate 502 and the side cover plate 503 is ≥15mm. The pad 501 is bolted to the floor slab 202 by anchor bolts. One end of the middle cover plate 502 is bolted to the explosion-proof outer ring or the explosion-proof inner wall 102 by anchor bolts, and the other end is laid flat on the upper surface of the pad 501. One end of the side cover plate 503 is bolted to the floor slab 202 by anchor bolts, and the other end is laid flat on the upper surface of the middle cover plate 502. The middle cover plate 502 can slide freely between the pad 501 and the side cover plate 503, thereby changing the distance between the deformation component 5 and the explosion-proof outer wall 101 or the explosion-proof inner wall 102, further ensuring the overall safety of the explosion-proof structure.

[0063] According to one embodiment provided by the present invention, such as Figure 1 and Figure 2 As shown, the deformable component 5 is also provided with an elastic rubber strip 504, which is laid on the upper surface of the middle cover plate 502, and the upper top surface of the elastic rubber strip 504 is flush with the upper top surface of the side cover plate 503.

[0064] In this embodiment, the deformable component 5 is also provided with an elastic rubber strip 505, which is laid on the upper surface of the middle cover plate 502, and its top surface is flush with the top surface of the side cover plate 503.

[0065] Preferably, the middle cover plate 502 has adhesive strips 505 added to the upper and lower surfaces of the end that can slide freely, thereby ensuring the overall safety of the explosion-proof structure.

One end of the sealing plate 601 is bolted to the frame column 201 by an anchor bolt, and the other end is bolted to the blast-resistant outer wall 101 or the blast-resistant inner wall 102 by an anchor bolt.

[0067] In this embodiment, a sealing plate 601 is provided between the frame column 201 and the explosion-proof outer wall 101 or the explosion-proof inner wall 102. Preferably, the sealing plate 601 is made of aluminum plate structure, the thickness of the sealing plate 601 is ≥2mm, and one end of the sealing plate 601 is bolted to the frame column 201 by anchor bolts, and the other end is bolted to the explosion-proof outer wall 101 or the explosion-proof inner wall 102 by anchor bolts. By setting the above-mentioned second deformation component 5, a certain deformation error rate is ensured between the frame column 201 and the explosion-proof outer wall 101 or the explosion-proof inner wall 102, further ensuring the safety of the internal structure of the frame.

[0069] In this embodiment, the load-bearing device includes a platform 401, which connects the load-bearing device to the blast-resistant outer wall 101, the blast-resistant inner wall 102, or the longitudinal frame column 201. The platform 401 is hinged to the blast-resistant outer wall 101, the blast-resistant inner wall 102, or the longitudinal frame column 201, ensuring that under explosion conditions, the blast-resistant outer wall 101, the blast-resistant inner wall 102, or the longitudinal frame column 201 can change their connection angle by hinges. This ensures that the inner frame assembly only bears the vertical load, thereby guaranteeing the safety and applicability of the blast-resistant structure.

[0070] The load-bearing device also includes engineering piles 402, one end of which is embedded in the lower end of the foundation 401 to ensure the overall stability of the blast-resistant structure.
