[0002] Setting up blast walls at a certain distance from the outside of a building can effectively reduce the destructive effects of the shock wave and fragments generated by a car bomb explosion, and is one of the common measures to protect important buildings from terrorist bomb attacks. Application publication number CN1687543 A, "Design Method of Multi-Layer Composite Explosion-Proof Wall," constructs a multi-layer composite explosion-proof wall by adding porous materials to the middle of a concrete wall. This maintains sufficient strength to resist the damage of explosive impact loads, preventing the wall structure from breaking and scattering, while the porous materials absorb and attenuate the energy of the explosive shock wave transmitted through the wall, reducing the damage to buildings and the probability of casualties due to accidental explosions. Authorization announcement number CN 100582411 C, "Prefabricated Explosion-Proof Wall and Flip-Up Barb Combination Protective Device," provides two types of prefabricated explosion-proof walls combined with one flip-up barb combination, aiming to mitigate the destructive effects of car bomb terrorist attacks on important buildings and overcome the shortcomings of sudden impact explosion protection devices. Authorization announcement number CN 101949184 B, "Portable Explosion-Proof Wall," provides a portable explosion-proof wall that can be quickly assembled according to changes in the incident location, aiming to solve the shortcomings of traditional explosion-proof walls that cannot be changed with the incident location. Authorization announcement number CN 103628583... B, "A Modular Mobile Explosion-Proof Wall," proposes a modular mobile explosion-proof wall to overcome the shortcomings of existing technologies, such as high cost, insufficient resistance, poor energy absorption, large total weight, poor stability, long construction time, and the need for mechanical installation. Authorization announcement number CN103981962. B, "A High-Performance Bionic Explosion-Proof Wall," provides a lightweight, high-strength, and rapidly constructable high-performance bionic explosion-proof wall to withstand blast shock waves, prevent wall cracking and debris splashing, overcome the defects of traditional single-layer explosion-proof walls, and reduce the damage to targets and personnel inside the explosion-proof wall through multi-layer energy dissipation.

[0003] Explosion-proof walls have undergone significant development, including modular and modular designs. However, most current explosion-proof walls rely on the inherent properties of the materials themselves for protection. For example, rigid materials like concrete and steel are used to withstand the impact of an explosion. Later, more flexible materials such as rubber and polyester foam were developed to absorb the impact. However, current explosion-proof walls are fixed installations. If the materials themselves cannot absorb a strong impact, the wall is easily damaged, failing to provide adequate protection. Furthermore, current technology lacks research on explosion-proof reinforcement for irregularly shaped walls (such as sloping walls). Summary of the Invention

[0004] This application provides a modular external spring damping mass system explosion-proof wall, which can be used to solve the technical problem that the existing explosion-proof walls have a simple structure and cannot withstand strong impact forces.

[0030] Each damper is placed inside its corresponding spring; small insert plates are welded to both sides of the spring so that the axis of the spring and the axis of the damper coincide.

[0031] The A spring damping subsystem and the B spring damping subsystem have the same structure. The A spring damping subsystem includes multiple dampers arranged at the same height.

This allows the support frame system and mass subsystem to move back and forth along the slide groove after being subjected to impact loads, transferring the impact load to the base subsystem and ultimately to the ground, thus ensuring the overall stability of the explosion-proof wall system; 6. This application addresses the lack of research on explosion-proof reinforcement of irregularly shaped walls under special circumstances in existing technologies, specifically for sloping walls.

In this embodiment, the modular external spring damped mass system explosion-proof wall consists of six basic explosion-proof wall unit modules. In this embodiment, one of the basic explosion-proof wall unit modules is described in detail as an example.

[0081] The basic unit module of the modular external spring damping mass system explosion-proof wall includes a base subsystem, a support frame system, a mass subsystem, and a spring damping subsystem. The basic unit modules can be interconnected laterally by means of lugs and U-bolts to form explosion-proof walls of different lengths using the external spring damping mass system.

[0082] The base subsystem of the basic unit module includes one base plate, two sliding grooves, two reinforcing rib supports, and 16 sheet metal bending slots. The base plate measures 3000mm × 1500mm × 15mm (length × width × thickness), and the sliding grooves measure 2000mm × 80mm × 40mm (length × width × height). The base plate, sliding grooves, reinforcing rib supports, and sheet metal bending slots are all made of steel, high-strength alloy materials, or high-strength engineering materials. The sliding grooves can be made of channel steel, U-shaped profiles, or U-shaped grooves made of steel plates. The sheet metal bending slots can be formed by bending steel plates. The sliding grooves and the base plate are fixed together by bolts or welding. The reinforcing rib supports and the base plate are fixed together by welding. The reinforcing rib supports and the sheet metal bending slots are fixed together by welding. The base subsystem fixes or supports the support frame system, mass subsystem, and spring damping subsystem on it, and is tightly connected to the ground. The slide groove on it ensures that the support frame system and mass subsystem can move back and forth along the slide groove after being subjected to impact loads, and dissipate energy through the spring damping subsystem. At the same time, the impact load transmitted from the spring damping subsystem is transferred to the base subsystem through the mass subsystem and support frame system, and finally to the ground, thereby ensuring the overall stability of the explosion-proof wall system.

[0083] The basic unit module's support frame system includes two triangular supports with casters, six horizontal braces, one short brace, four cross braces, 16 sheet metal bending slots, 40 corner brackets, six side frame slots, ten side frame slot reinforcing ribs, three bottom frame slots, two wheel stops, six hanging lugs, three U-bolts, and six nuts. All components are made of steel, high-strength alloy materials, or high-strength engineering materials. The triangular supports with casters, horizontal braces, and cross braces can all be made of profiles. The sheet metal bending slots can be made from bent steel plates. The corner brackets can be selected from standard parts based on the angular relationships between the components. Both the base frame and the bottom frame slots can be made of channel steel or U-shaped profiles. The side frame slot reinforcing ribs and wheel stops are made of steel plates. The wheels and nuts are standard parts. The lugs and U-bolts are machined from steel, high-strength alloy materials, or high-strength engineering materials. The horizontal brace is 1080mm long, and the cross braces are 170mm, 525mm, and 970mm long, respectively. The right-angled triangular space frame, horizontal braces, and cross braces are all made of standard steel profiles with a cross section of 80mm×80mm. Each side frame consists of 3 side frame slots, and each side frame slot measures 3065mm×50mm×100mm (length×width×height).

Sixteen sheet metal bending slots are welded to the front and rear outer side baffles of the caster frame. Three slots are welded together to form a single side frame slot, which is then welded to the triangular support with the caster, forming a triangular support with casters and the integrated side frame slot. First, two... Triangular supports with casters and integrated side frame slots are installed in the grooves of the base plate. Six horizontal braces are fixed between the vertical hypotenuses of two triangular supports using angle brackets, and one short brace is fixed between the top set of horizontal braces. Four cross braces are fixed between the three sets of horizontal braces using angle brackets. Next, the bottom frame slot with the slot facing upwards is fixed into the groove of the wheel bracket using bolts. Then, the front and rear sides of the side frame slot are fixed together with the side frame slot reinforcing ribs and bolts, making the side frame slot and the bottom frame slot a whole, preventing the frame from deforming and affecting the insertion of the insert plate. Finally, a mesh support frame system is formed. The support frame system can withstand the impact load transmitted from the mass subsystem and transmit the impact load to the base subsystem through external spring damping, and then to the ground through the base subsystem, thereby ensuring the overall stability of the explosion-proof wall system.

[0084] The mass subsystem of the basic unit module includes six insert plates; the insert plates are made of steel, high-strength alloy materials, or high-strength engineering materials; the insert plates are machined from steel plates, but can also be made from other engineering materials; the dimensions of the insert plates are 1523mm × 1460mm × 20mm (length × width × thickness); the insert plates are inserted into the slots of the support frame subsystem. In actual use, the material and quantity of the insert plates can be flexibly selected and combined according to actual needs. The mass subsystem directly bears the explosive impact load, and the insert plates can effectively resist the effects of shock waves and fragments, while the wheels ensure free movement after being subjected to impact loads, and the sheet metal bending slots on the side frame slot reinforcing ribs can transfer the impact load to the spring damping subsystem.

[0085] The basic unit module's spring-damping subsystem includes 16 springs, 16 dampers, and 32 small inserts. Standard springs and dampers can be used; the springs are D100mm×645mm, and the dampers are either cylinder-type or hydraulic dampers with a diameter of Φ50mm and a length of 635mm. The small inserts are machined from steel plates. First, the dampers are placed inside the springs; then, the small inserts are fixed to both ends of the dampers with bolts; finally, the springs are welded to the small inserts, ensuring the spring's axis coincides with the damper's axis. The spring-damping subsystem is distributed between the support frame subsystem and the base subsystem. It is a crucial component of the modular external spring-damped mass system explosion-proof wall, serving to dissipate energy and transmit force. It effectively dissipates the impact energy transmitted from the support frame system and transfers the attenuated impact load to the base subsystem.

[0086] The components of the base subsystem, support frame system, mass subsystem, and spring damping subsystem of the basic unit module can be coated with ceramic material to improve the impact resistance, high temperature resistance, wear resistance, corrosion resistance, and weather resistance of the explosion-proof wall as a whole and its components. The coating thickness of the insert plate is 6mm, and the coating thickness of the other components is 2mm.

[0087] The assembly relationship of the base subsystem, support frame system, mass subsystem, and spring damping subsystem of the basic unit module is as follows: First, fix the base subsystem to the ground with expansion bolts or ground nails; then set the support frame system on the slide groove of the base subsystem; then set the mass subsystem in the slot of the support frame system; finally, set the spring damping subsystem in the sheet metal bending slot of the support frame system and the base subsystem.

The slide groove on it ensures that the support frame system and mass subsystem can move back and forth along the slide groove after being subjected to impact loads, and dissipate energy through the spring damping subsystem. At the same time, the impact load transmitted from the spring damping subsystem is transferred to the base subsystem through the mass subsystem and support frame system, and finally to the ground, thereby ensuring the overall stability of the explosion-proof wall system.

[0092] The basic unit module's support frame system includes two triangular supports with casters, six horizontal braces, one short brace, four cross braces, 16 sheet metal bending slots, 40 corner brackets, six side frame slots, ten side frame slot reinforcing ribs, three bottom frame slots, two wheel stops, six hanging lugs, three U-bolts, and six nuts. All components are made of steel, high-strength alloy materials, or high-strength engineering materials. The triangular supports with casters, horizontal braces, and cross braces can all be made of profiles; the sheet metal bending slots can be made from bent steel plates; and the corner brackets can be standard parts selected based on the angular relationships between the components. The base frame slots can be made of channel steel or U-shaped profiles. The side frame slot reinforcing ribs and wheel stops are made of steel plates. Wheels and nuts are standard parts. Lugs and U-bolts are machined from steel, high-strength alloy materials, or high-strength engineering materials. The horizontal brace is 1080mm long, and the cross braces are 170mm, 525mm, and 970mm long respectively. The right-angled triangular space frame, horizontal braces, and cross braces are all standard steel profiles with a cross-section of 100mm × 100mm. Each side frame consists of three side frame slots, each measuring 3065mm × 60mm × 120mm (length × width × height). The reinforcing rib measures 1500mm × 150mm × 15mm (length × width × thickness), the U-bolt diameter is Φ20mm, the hanging ear measures 150mm × 40mm × 90mm (length × width × height), and the wheel rim baffle measures 1000mm × 90mm × 10mm (length × width × thickness). Sixteen sheet metal bending slots are welded to the front and rear outer side rims of the caster frame. Three slots are welded together to form a single side frame slot, which is then welded to the triangular support with the caster, forming a triangular support with casters and the integrated side frame slot. First, two... Triangular supports with casters and integrated side frame slots are installed in the grooves of the base plate. Six horizontal braces are fixed between the vertical hypotenuses of two triangular supports using angle brackets, and one short brace is fixed between the top set of horizontal braces. Four cross braces are fixed between the three sets of horizontal braces using angle brackets. Next, the bottom frame slot with the slot facing upwards is fixed into the groove of the wheel bracket using bolts. Then, the front and rear sides of the side frame slot are fixed together with the side frame slot reinforcing ribs and bolts, making the side frame slot and the bottom frame slot a whole, preventing the frame from deforming and affecting the insertion of the insert plate. Finally, a mesh support frame system is formed. The support frame system can withstand the impact load transmitted from the mass subsystem and transmit the impact load to the base subsystem through external spring damping, and then to the ground through the base subsystem, thereby ensuring the overall stability of the explosion-proof wall system.

[0093] The mass subsystem of the basic unit module includes six insert plates; the insert plates are made of steel, high-strength alloy materials, or high-strength engineering materials; the insert plates are machined from steel plates, but can also be made from other engineering materials; the dimensions of the insert plates are 1523mm × 1460mm × 30mm (length × width × thickness); the insert plates are inserted into the slots of the support frame subsystem. In actual use, the material and quantity of the insert plates can be flexibly selected and combined according to actual needs. The mass subsystem directly bears the explosive impact load, and the insert plates can effectively resist the effects of shock waves and fragments, while the wheels ensure free movement after being subjected to impact loads, and the sheet metal bending slots on the side frame slot reinforcing ribs can transfer the impact load to the spring damping subsystem.

[0094] The basic unit module's spring-damping subsystem includes 16 springs, 16 dampers, and 32 small inserts. Standard springs and dampers can be used; the springs are D120mm×650mm, and the dampers are either pneumatic or hydraulic dampers with a diameter of Φ60mm and a length of 640mm. The small inserts are machined from steel plates. First, the dampers are placed inside the springs; then, the small inserts are fixed to both ends of the dampers with bolts; finally, the springs are welded to the small inserts, ensuring the spring's axis coincides with the damper's axis. The spring-damping subsystem is distributed between the support frame subsystem and the base subsystem, and is an important component of the modular external spring-damped mass system explosion-proof wall. It plays a role in energy dissipation and force transmission, effectively dissipating the impact energy transmitted from the support frame system and transferring the attenuated impact load to the base subsystem.

[0095] The components of the base subsystem, support frame system, mass subsystem, and spring damping subsystem of the basic unit module can be coated with polyurea material to improve the impact resistance, high temperature resistance, wear resistance, corrosion resistance, and weather resistance of the explosion-proof wall as a whole and its components. The coating thickness of the insert plate is 6mm, and the coating thickness of the other components is 2mm.

[0096] The assembly relationship of the base subsystem, support frame system, mass subsystem, and spring damping subsystem of the basic unit module is as follows: First, fix the base subsystem to the ground with expansion bolts or ground nails; then set the support frame system on the slide groove of the base subsystem; then set the mass subsystem in the slot of the support frame system; finally, set the spring damping subsystem in the sheet metal bending slot of the support frame system and the base subsystem.

[0097] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application.
