Description

Technical Field

[0001] This application relates to the field of explosion-proof technology, and in particular to an explosion-proof wall with a spring-damped mass system. Background Technology

[0002] Setting up blast walls at a certain distance from the exterior of a building can effectively reduce the destructive effects of shock waves and fragments generated by car bomb explosions, and is one of the common measures for protecting important buildings from explosions. According to structural type, blast walls can be divided into three types: rigid blast walls, flexible blast walls, and inertial blast walls. Rigid blast walls have high strength and stiffness, and are basically not damaged under explosive loads. They can be considered approximately as elastic bodies, such as blast walls made of reinforced concrete and reinforced soil. Their blast protection mechanism mainly involves the reflection and flow around the shock wave during propagation, weakening the shock wave. Flexible blast walls have a certain degree of ductility and fragility. Under explosive loads, the wall will undergo plastic deformation or breakage, such as masonry blast walls, steel plate composite blast walls, and composite material (artificial fiber) blast walls. Their blast protection mechanism, in addition to reducing the impact of shock waves during propagation, also involves the reflection and flow around the shock wave during propagation, weakening the shock wave. In addition to reflection and diffraction during the process, the deformation or breakage of the wall will also dissipate some of the shock wave energy. Inertial explosion-proof walls are made of materials such as sand or water. When subjected to the impact of an explosion, the wall will scatter, using kinetic energy to dissipate the shock wave energy and weaken the shock wave. Examples include sandbag explosion-proof walls, water explosion-proof walls, and plastic prefabricated explosion-proof walls. Their explosion-proof mechanism mainly utilizes the kinetic energy of the wall material scattered when subjected to an explosion to consume some of the shock wave energy. Before the wall material scatters, it can also cause the shock wave to be reflected and diffracted.

[0003] Although movable prefabricated blast-proof walls have emerged to meet practical needs, they are not as robust as fixed blast-proof walls. When exposed to a shock wave, if the wall cannot effectively absorb and weaken its impact, the movable prefabricated wall may shift entirely. To address this issue, technicians and researchers are continuously studying blast-proof wall materials, evolving from simple sandbags to reinforced concrete, steel plate sandwich panels, high-fiber fabrics, water-based blast-proof walls, and irregularly shaped blast-proof walls, among other forms of blast-proof structures. The emergence of new materials is driving continuous progress in blast-proof wall research. However, current blast-proof walls only absorb and dissipate shock waves on their surface. If the shock wave is large, it may penetrate deep into the wall. For movable blast-proof walls, the internal absorption of shock waves can damage the wall, thus reducing its blast-proof effectiveness. Summary of the Invention

The dimensions of the reinforcing ribs in the side frame slots are 1500mm × 120mm × 10mm. The dimensions are mm (length × width × thickness), U-bolt diameter is Φ20mm, hanging ear size is 150mm × 30mm × 83mm (length × width × height), wheel side baffle size is 450mm × 90mm × 5mm (length × width × thickness); depending on actual needs, the U-bolt diameter can also be Φ25mm; hanging ear size is 150mm × 40mm × 90mm (length × width × height), wheel side baffle size is 450mm × 90mm × 10mm (length × width × thickness); the sheet metal bending slot is fixed to one side of the side frame slot reinforcement rib by welding; first, the wheel and wheel baffle are fixed separately by bolts. At the bottom and outer side of the wheel bracket, the wheels are set in the grooves of the base. Next, the bottom frame slots with upward-facing grooves are fixed to the grooves of the wheel bracket using bolts. Then, three side frame slots, welded together to form a single unit, are placed at one end of the bottom frame slot, with the grooves facing inwards; the same applies to the other side. The bottom ends of the side frame slots and the wheel bracket are then fixed together using side frame wheel bracket reinforcing ribs and angle brackets.

Finally, the insert plate is inserted into the slot. The mass subsystem directly bears the explosive impact load, and the insert plate effectively resists the effects of shock waves and fragments. Simultaneously, the wheels ensure free movement after impact loads, and the sheet metal bending slot structure on the side frame slot reinforcing ribs transmits the impact load to the spring damping subsystem.

Alternatively, depending on the specific needs, springs can be D120mm×645mm, and dampers can be either cylinder-type or hydraulic dampers with a diameter of Φ60mm and a length of 635mm. The small insert plates are also machined from steel plates. First, the dampers are placed inside the springs. Then, the small insert plates are fixed to both ends of the dampers with bolts. Finally, the springs are welded to the small insert plates, ensuring that the spring's axis coincides with the damper's axis. The spring-damping subsystem is distributed between the mass subsystem and the support frame system.
