Description

Technical Field

[0001] The present invention belongs to the field of explosion-proof shelters, and in particular relates to an assembled explosion-proof house. Background Art

[0002] Blast-resistant housing, also known as explosion-proof housing, is a specialized building structure designed for high-risk environments. Its robust explosion-proof structure and sealed design effectively withstand the shock and pressure of an external explosion, protecting the equipment and personnel within. The high-strength, corrosion-resistant, and impact-resistant materials used in blast-resistant housing, such as explosion-proof steel plates and aluminum alloy composite panels, not only possess excellent physical properties but also effectively block the transmission of explosion shock waves, minimizing damage to the blast-resistant housing.

[0003] Explosion-resistant housing is now widely used in a variety of industries and fields. For example, in the military and defense sectors, blast-resistant housing is often used as a command post, communication center, or shelter. In scientific research, especially in situations involving flammable chemicals and high-voltage experiments, blast-resistant housing provides a safe research platform for researchers. In mining and tunneling projects, blast-resistant housing is often used as a monitoring room, shelter, or emergency rescue station. In the chemical and petroleum industries, blast-resistant housing serves as a critical control room, effectively isolating potential explosion risks and protecting operators from the impact of explosions and harmful gases.

[0004] In addition to the aforementioned applications, blast-resistant housing is also widely used in a variety of specialized fields, including oil and gas field exploration, hazardous materials transportation, and nuclear power plant auxiliary facilities. In these settings, blast-resistant housing, with its superior protective performance and diverse functional designs, provides a solid safety guarantee for various high-risk operations. Consequently, blast-resistant housing, with its unique protective capabilities and wide range of applications, has become an indispensable safety barrier in modern industrial and scientific research activities, playing a particularly critical role in ensuring personnel safety and maintaining stable equipment operation.

[0005] To ensure effective explosion resistance, existing blast-resistant housing typically utilizes a one-piece design, integrating the bottom, top, and side walls into a single, non-detachable unit. While this integrated design offers excellent blast protection, it suffers from limited dimensions, making it difficult to meet the needs of diverse applications and inconvenient to transport. Furthermore, if subjected to a single-point impact, the entire blast-resistant housing would become scrapped due to the inability to replace any part, resulting in high operational costs.

[0033] See also Figure 9As shown, the steel square tube and the steel tenon connector are plug-fitted and fixedly connected by bolts. When assembling the steel structure cage frame 1, the long side left tenon and the long side right tenon are respectively inserted into one end of the corresponding long side square tube 103 and fixed by bolts; the long side lower tenon is inserted into one end of the corresponding column square tube 104 and fixed by bolts; the long side inner tenon is inserted into one end of the corresponding crossbeam square tube 105 and fixed by bolts; the short side left tenon and the short side right tenon are respectively inserted into one end of the corresponding short side square tube 102 and fixed by bolts; the short side lower tenon is inserted into one end of the corresponding column square tube 104 and fixed by bolts; the corner lower tenon is inserted into one end of the corresponding corner column square tube 101 and fixed by bolts; the corner front / rear tenon is inserted into one end of the corresponding short side square tube 102 and fixed by bolts; the corner left / right tenon is inserted into one end of the corresponding long side square tube 103 and fixed by bolts.

[0034] See also Figure 2 As shown, under the separating effect of the column square tube 104 and the beam square tube 105, the six sides of the steel structure cage frame 1 are evenly divided into a plurality of explosion-proof wall installation openings, and an explosion-proof door installation opening is opened on one side of the steel structure cage frame 1.

[0035] See also Figure 1 As shown, the entrance explosion-proof door 3 is installed in the explosion-proof door mounting opening, and each explosion-proof wall mounting opening is installed with a corresponding modular explosion-proof wall panel 2. Depending on the design requirements, the dimensions of the explosion-proof wall mounting openings on the four sides may differ from those on the top and bottom surfaces, and the corresponding dimensions of the modular explosion-proof wall panels 2 on the four sides may also differ from those on the top and bottom surfaces.

[0036] See also Figure 10 As shown, the modular explosion-proof wall panel 2 is composed of at least a cover plate 201, a bottom shell 202, an explosion-proof filling material, and an explosion-proof coating. The cover plate 201 is placed on the bottom shell 202, forming a closed space between the two. The planar dimensions of the cover plate 201 are larger than the planar dimensions of the bottom shell 202. After being placed on the bottom shell 202, the cover plate 201 forms a circle of protruding ribs around the bottom shell 202. The explosion-proof filling material completely fills the sealed space, and the explosion-proof filling material can be made of polyurethane foam material. The explosion-proof coating is completely coated on the outer side of the cover plate 201, and the explosion-proof coating can be made of explosion-proof polyurea coating.

[0037] See also Figure 11As shown, when the modular explosion-proof wall panel 2 is installed in place on the steel cage frame 1, the modular explosion-proof wall panel 2 is completely sealed and connected to the explosion-proof wall installation opening. Specifically, the bottom shell 202 is completely embedded in the explosion-proof wall installation opening, and the retaining edge is aligned with the steel square tube on the front side of the explosion-proof wall installation opening and is fixedly connected by bolts. The retaining edge completely covers the edges of the explosion-proof wall installation opening, thereby achieving a completely sealed connection between the modular explosion-proof wall panel 2 and the explosion-proof wall installation opening.

[0038] See also Figure 10 As shown, a circle of fixed frame 4 can be set between the modular explosion-proof wall panel 2 and the explosion-proof wall installation opening to play a reinforcing role, thereby forming an internal and external fixed double fixation with the retaining edge. The fixed frame 4 is formed by welding four L-shaped angle irons together, and a groove is respectively opened at the inner end of each of the four sides of the bottom shell 202, thereby forming a circle of fixed frame installation grooves 203. The four L-shaped angle irons of the fixed frame 4 are respectively located in the four grooves of the fixed frame installation groove 203, and one vertical surface of the L-shaped angle iron is in contact with the side surface of the fixed frame installation groove 203 and is fixedly connected by bolts. The other vertical surface of the L-shaped angle iron is in contact with the steel square tube on the inner side surface of the explosion-proof wall installation opening and is fixedly connected by bolts.

[0039] See also Figure 12 As shown, since the steel square tube and the steel tenon connector are assembled with bolts, this will cause the tail or head of the bolt to extend into the explosion-proof wall installation opening. Therefore, L-shaped avoidance grooves 204 can be opened at the top corners of the bottom shell 202 to avoid the head or tail of the bolt of the steel structure cage frame 1 from extending into the opening, thereby preventing interference during installation.

[0040] According to usage requirements, the explosion-proof house is also equipped with one or more of a fresh air system, an oxygen supply system, a power generation system, an energy storage system, a communication system or a lighting system.

[0041] The installation process of the assembled explosion-proof house of the present invention is as follows: After all the bulk parts of the prefabricated explosion-proof house are transported to the site, the bottom of the steel cage frame is built first, and the modular explosion-proof wall panels are laid on the bottom of the steel cage frame. Then the columns and top of the steel cage frame are installed, and the modular explosion-proof wall panels and entrance explosion-proof doors are installed on the four sides of the steel cage frame. Finally, the modular explosion-proof wall panels are installed on the top of the steel cage frame to complete the overall installation.

[0042] As can be seen from the above installation process, the prefabricated explosion-proof house of the present invention is first transported to the site in a disassembled form and then quickly assembled in modular form. It is not only convenient to transport and install, but also its size can be customized. Moreover, when it suffers a single-point impact, it only needs to directly replace the damaged modular explosion-proof wall panel, which will not cause the entire explosion-proof house to be scrapped, greatly reducing the use and maintenance costs.

[0043] The present invention adopts a modular design, so its size can be customized according to customer needs. The size of the steel structure cage frame 1, the size and number of the explosion-proof wall installation openings, the size and number of the explosion-proof door installation openings, and the size and number of the modular explosion-proof wall panels 2 can all be adjusted.

[0044] The dimensions of a preferred embodiment of the present invention are described in detail below: The steel cage frame 1 is a rectangular cage frame structure as a whole, with an external dimension of 6390 mm in length, 2970 mm in width, and 2640 mm in height, and an internal net dimension of 6150 mm in length, 2730 mm in width, and 2400 mm in height.

[0045] The steel square tube is a hot-dip galvanized steel square tube with a cross-sectional size of 120 mm*120 mm and a wall thickness of 4 mm. The steel tenon connector is a 120 series steel tenon connector.

[0046] The top surface, bottom surface and two long side surfaces of the steel structure cage frame 1 are divided into 11 explosion-proof wall installation openings, one short side surface of the steel structure cage frame 1 is divided into 5 explosion-proof wall installation openings, and the other short side surface is divided into 3 explosion-proof wall installation openings and 1 explosion-proof door installation opening.

[0047] The entrance explosion-proof door 3 is a finished explosion-proof door, which is installed in the explosion-proof door installation opening and has a size of 2400mm high*1020mm wide*100mm thick.

[0048] The modular explosion-proof wall panels 2 are divided into modular explosion-proof horizontal panels and modular explosion-proof vertical panels. The cover plate 201 of the modular explosion-proof wall panels 2 is made of patterned steel plate with a thickness of 4mm, and the bottom shell 202 of the modular explosion-proof wall panels 2 is made of steel plate with a thickness of 3mm.

[0049] The modular explosion-proof transverse panels are installed in the explosion-proof wall installation openings located at the top and bottom surfaces of the steel structure cage frame 1 , and their dimensions are 450 mm wide, 2730 mm long, and 100 mm thick.

[0050] The modular explosion-proof vertical panels are installed in the explosion-proof wall installation openings located at the two short side surfaces and the two long side surfaces of the steel structure cage frame 1, and their dimensions are 450mm wide*2400mm long*100mm thick.

[0051] The maximum component weight of the explosion-proof house does not exceed 100kg, and the longest component size is 2790mm.

[0052] The explosion-proof house can be equipped with 6 800*2000 high and low double beds (up for working during the day / down for rest at night) and 8 rest seats, which can accommodate 20 people for rest.

[0053] The protection capability of the explosion-proof house is 1.0m of covering soil (medium soil) and resistance to 155mm grenade with instantaneous fuse.

[0054] The applicant commissioned the Ministry of Education Engineering Research Center for Explosion Safety Protection and the School of Civil Engineering at Southeast University to conduct static explosion tests on the shallow-buried shelter structure of the prefabricated explosion-resistant housing provided by the present invention. This test, through explosion testing, primarily accomplished the following objectives: testing and verifying the overall structure's performance against 81mm mortar and 155mm grenade explosions; verifying the deformation and damage patterns of the roof and side walls; measuring and verifying the surface load, internal explosion overpressure / negative pressure, and the distribution of compression waves in the soil; testing the structure's ultimate explosion resistance, and providing recommendations for further structural design optimization.

[0055] This experiment studied the protective performance of shallow-buried shelters against ground blasts of 81mm mortar shells and 155mm grenades through field explosion tests and numerical simulation methods. The following conclusions were drawn: 1. When the 81mm mortar shell exploded in the middle of the roof span, the shelter structure was basically in an elastic working state with a large safety margin. The overpressure / negative pressure inside the structure did not cause obvious physical damage to the test ram.

[0056] 2. When a 155mm grenade detonated mid-span at the roof, no significant deformation or damage was observed at the roof or its connection points when the soil cover was 1.5m. When the soil cover was 1.0m, the longitudinal beams of the roof yielded and deflected approximately 8.3cm, but the overall structure showed no collapse or soil leakage. The internal overpressure / negative pressure did not cause significant physical damage to the test rams.

[0057] 3. When the cover soil of the shelter is frozen soil, the numerical simulation results show that the shelter can prevent the 155mm grenade from exploding at the center of the top cover when the cover soil is 1.0m thick.

[0058] It can be seen from the above test results that the assembled explosion-proof house provided by the present invention has excellent explosion-proof and explosion-proof effects, and its performance is comparable to that of the traditional integrated explosion-proof house.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
