Description

Technical Field

[0001] This utility model relates to a building component, specifically a bulletproof and blast-resistant roof structure, belonging to the field of building component technology. Background Technology

[0002] In certain specialized architectural fields, such as the buildings of some embassies and consulates abroad, more stringent design specifications are often imposed on the building's resistance to damage. For example, some roofs are required to withstand rocket attacks.

[0003] For example, without considering the possibility of interior decorative surfaces and components falling off, or the possibility of shock waves entering the room through unsealed parts such as doors and windows and causing damage, the roof should be able to withstand an attack by a 107mm rocket, with the main building structure not collapsing, beams and columns not failing, and floors not being penetrated.

[0004] In existing technologies, the design of the joints of the blast-resistant structure for roof surfaces is relatively weak, and there are also deficiencies in the comprehensiveness of the structural design in terms of energy absorption, impact resistance, and puncture prevention. Summary of the Invention

[0005] The purpose of this invention is to provide a bulletproof and blast-resistant roof structure to solve the aforementioned technical problems.

[0006] The present invention adopts the following technical solution:

[0007] A bulletproof and blast-resistant roof structure includes a composite armor module plate 1, a pressure plate 3, and fasteners. The composite armor module plate 1 includes a bottom steel plate 106 and an blast-resistant composite layer structure located on top of it. The bottom steel plate 106 extends laterally from the blast-resistant composite layer structure by an extension section. The extension sections of adjacent composite armor module plates 1 are spliced ​​together and covered by a pressure plate 3. The fasteners pass through the pressure plate 3 and the bottom steel plate 106 to connect adjacent composite armor module plates 1 into one unit.

[0008] This technical solution provides a composite armor module plate with a special structure. This design allows for rapid and efficient splicing between adjacent explosion-proof plate structures. At the same time, the spliced ​​structure is connected by pressure plates and fasteners, while also ensuring the explosion resistance at the splice joint.

[0009] Preferably, the explosion-proof composite layer structure includes, from bottom to top, a ceramic sheet layer 104, a foamed aluminum board layer 103, an energy-absorbing and penetration-blocking structural layer 102, and a waterproof and explosion-proof layer 101; the ceramic sheet layer 104 has ceramic sheets arranged in transverse segments inside, and adjacent ceramic sheets are separated by aluminum sheet partitions 107; the foamed aluminum board layer 103 is an aluminum board structure with a porous foam structure inside, made by a foaming process; the energy-absorbing and penetration-blocking structural layer 102 is made of ultra-high molecular weight polyethylene material with at least one of steel wire mesh and aramid fabric sandwiched inside; the waterproof and explosion-proof layer 101 is a cement board with a waterproof layer on the surface.

[0010] Furthermore, the waterproof layer on the surface of the waterproof and explosion-proof layer 101 is made of steel plate skin.

[0011] Furthermore, the explosion-proof composite layer structure has a side panel 105, which is welded and fixed to the bottom steel plate 106. The function of the side panel is to improve the overall integrity of the explosion-proof composite layer structure and ensure its integrity during transportation and installation.

[0012] Furthermore, the enclosure 105 is made of steel plate.

[0017] 1) A composite armor module plate with a special structure is provided. This design allows for rapid and good splicing between adjacent explosion-proof plate structures. At the same time, the spliced ​​structure is connected by pressure plates and fasteners, while ensuring the explosion resistance of the splice.

[0018] 2) An innovative design was implemented for the structure of the composite armor module plate, including:

[0019] The bottom steel plate 106 provides good support and rigidity, the ceramic sheet layer 104 has good impact resistance, the aluminum partition 107 protects the ceramic sheets during transportation and hoisting, the foam aluminum plate layer 103 provides flat support and energy absorption, the energy-absorbing and penetration-resistant structural layer 102 absorbs energy, and its internal aramid cloth layer or steel wire mesh layer provides tough penetration resistance.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] See Figure 2 A bulletproof and blast-resistant roof structure includes a composite armor module plate 1, a pressure plate 3, and fasteners; the fasteners used here are bolts 2 and nuts.

[0027] See Figure 1-2 The composite armor module 1 includes a bottom steel plate 106 and an explosion-proof composite layer structure located on top of it; the bottom steel plate 106 extends laterally out of the explosion-proof composite layer structure by an extension section, the extension sections of adjacent composite armor module 1 are spliced ​​together and covered by a pressure plate 3; the fasteners pass through the pressure plate 3 and the bottom steel plate 106 to connect adjacent composite armor module 1 into one unit.

[0028] The design of this special composite armor module plate allows for rapid and efficient splicing between adjacent explosion-proof plate structures. At the same time, the splicing structure is connected by pressure plates and fasteners, while also ensuring the explosion-proof capability of the splice.

[0029] See Figure 1The explosion-proof composite layer structure comprises, from bottom to top, a ceramic sheet layer 104, a foamed aluminum board layer 103, an energy-absorbing and penetration-blocking structural layer 102, and a waterproof and explosion-proof layer 101. The ceramic sheet layer 104 has ceramic sheets arranged in horizontal segments inside, and adjacent ceramic sheets are separated by aluminum sheet partitions 107. The foamed aluminum board layer 103 is an aluminum board structure with a porous foam structure inside, made by a foaming process. The energy-absorbing and penetration-blocking structural layer 102 is made of ultra-high molecular weight polyethylene material with at least one of steel wire mesh and aramid fabric sandwiched inside. The waterproof and explosion-proof layer 101 is a cement board with a waterproof layer on the surface.

[0030] It should be noted that aluminum foam board is a known material, a new type of ultralight porous metal material formed by combining metallic aluminum and gas, with aluminum or aluminum alloy as the matrix and containing a large number of air bubbles. It perfectly combines the strength, heat resistance, and processability of metallic aluminum with the lightweight, sound insulation, heat insulation, and energy absorption properties of air bubbles.

[0031] It should be noted that ultra-high molecular weight polyethylene is a known material, and it has higher wear resistance than ordinary polyethylene.

[0032] In this embodiment, see Figure 1 The waterproof and explosion-proof layer 101 has a steel plate skin on its surface, thus forming a composite board structure. The steel plate skin is not shown in the attached drawings.

[0033] In this embodiment, see Figure 1 The explosion-proof composite layer structure has a surrounding plate 105 on its side. The function of the surrounding plate is to improve the overall integrity of the explosion-proof composite layer structure and ensure its integrity during transportation and installation.

[0034] In this embodiment, see Figure 1 The enclosure 105 is a steel plate.

[0035] In this embodiment, see Figure 2 The pressure plate 3 is a steel plate.

[0036] In this embodiment, see Figure 2 A pad is provided at the lower part of the composite armor module plate 1 where it contacts the nut. The pad is not marked with the reference numeral.

[0037] Composition method: Weld the enclosure 105 to the bottom steel plate 106, then use glue to arrange the ceramic sheet 104 and the partition 107 flat in sequence, apply glue to the flat surface, place the foam aluminum plate 103 on it, apply glue to the surface again, place the energy-absorbing and penetration-blocking structural layer 102 on it, apply glue to the surface again, and then place the waterproof and explosion-proof layer 101 on it.

[0038] Connection method: The bottom steel plates 106 of two adjacent composite armor module plates 1 are spliced ​​together, and the pressure plate 103 is placed on top and fastened with bolts 2, washers and nuts.

[0039] This utility model provides a composite armor module plate with a special structure. This design allows for rapid and efficient splicing between adjacent explosion-proof plate structures. At the same time, the spliced ​​structure is connected by pressure plates and fasteners, while also ensuring the explosion-proof capability of the splice.

The bottom steel plate 106 provides excellent support and rigidity; the ceramic sheet layer 104 offers good impact resistance; the aluminum partition 107 protects the ceramic sheets during transportation and hoisting; the foamed aluminum plate layer 103 provides flat support and energy absorption; the energy-absorbing and penetration-resistant structural layer 102 absorbs energy, while its internal aramid fabric or wire mesh layer provides tough penetration resistance; and the waterproof and explosion-proof layer 101 is a composite structure of cement board and waterproof layer, serving both explosion-proof and waterproof purposes, as well as aesthetics. A side panel design was incorporated into the composite armor module plate, improving the overall integrity of the explosion-proof composite layer structure and ensuring its integrity during transportation and installation.
