Technical Field

[0001] The invention belongs to the field of explosion-proof engineering, and in particular relates to an integral coordinated concrete explosion-proof wall. Background Art

[0002] Various flammable and explosive petrochemical products often cause huge casualties and economic losses due to explosions. In order to maximize the control of the losses caused by fire and explosion, it is necessary to develop explosion-proof walls with good explosion-proof effects, especially in military fortifications such as warehouses, shooting ranges, dormitories, ammunition depots, command posts, garages, hangars, oil depots, equipment rooms, temporary warehouses, bomb disposal sites, field hospitals and checkpoints, as well as various flammable and explosive petrochemical product processing plants. Often, huge casualties and economic losses are caused by explosions. In order to maximize the control of the losses caused by fire and explosion, it is necessary to build a series of projects such as military safety explosion-proof walls, three-dimensional fortification explosion-proof walls, training base explosion-proof walls, field material warehouse explosion-proof walls, field camp explosion-proof walls, dangerous goods warehouse explosion-proof walls, chemical plant explosion-proof walls, refinery explosion-proof walls, firecracker factory explosion-proof walls, reserve warehouse explosion-proof walls, and barracks explosion-proof walls. In response to this series of problems, explosion-proof walls need to have high crack resistance, strong impact resistance, be able to withstand great impact pressure, have good resistance to explosion pressure, have extremely strong explosion resistance, high strength, great deformation capacity, and good buffering performance. They can absorb the energy generated by the explosion impact to the maximum extent, can significantly control the disasters caused by the explosion, and can effectively play the role of crack resistance, anti-seepage and explosion prevention.

At the same time, the supporting effect of multiple energy-absorbing extrusion supporting steel plate fans enables the overall structure to have explosion-proof shock absorption and buffering energy consumption while having sufficient strength.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

It is characterized in that: in the integral coordinated concrete explosion-proof wall, the overall structure is symmetrical, the energy-absorbing fixed steel plate is arranged in the middle of the structure, and the outer arch connection type energy-absorbing steel plate, energy absorption and shock absorption layer, explosion-proof fiber concrete, explosion-proof polymer coating are symmetrically arranged on both sides of the energy-absorbing fixed steel plate in sequence, the outer arch connection type energy-absorbing steel plate is composed of a plurality of outer arch steel plate units connected, and a plurality of energy-absorbing extrusion support steel plate fans are arranged. One end of it is vertically connected to the energy absorbing fixed steel plate, and the other end is connected to the high-strength fixed hinge. A number of energy-absorbing extrusion support steel plate fans are arranged, one end of which is connected to the energy absorbing fixed steel plate, and the other end is connected to the high-strength fixed hinge. In the high-strength fixed hinge contained in the same outer arch steel plate unit, adjacent high-strength fixed hinges are connected by elastic support connecting rods. In the high-strength fixed hinges contained in different outer arch steel plate units, ordinary fixed hinges are arranged between adjacent high-strength fixed hinges. The ordinary fixed hinge and the high-strength fixed hinges on both sides thereof are connected by elastic force transmission connecting rods. At the same time, the ordinary fixed hinge and the energy absorbing fixed steel plate are connected by energy-absorbing support connecting steel plates. The high-strength fixed hinges are in contact with the outer arch-type connected energy-absorbing steel plates arranged on the outside thereof, and the cavity between the two outer arch-type connected energy-absorbing steel plates is filled with damping material concrete.

[0006] Furthermore, the outer arch-type connecting energy-absorbing steel plate, the energy-absorbing extruded supporting steel plate fan, the energy-absorbing extruded supporting steel plate fan, the energy-absorbing supporting connecting steel plate, and the energy-absorbing fixing steel plate are made of low-yield point steel plates.

[0007] Furthermore, the elastic force supporting connecting rod and the elastic force transmitting connecting rod are made of elastic material.

[0008] Furthermore, the energy absorbing and shock absorbing layer is made of asphalt, rubber, and silicone resin materials, and is injection-molded together with a hardening additive to form a shock absorbing layer after hardening.

[0009] Furthermore, the damping material filled concrete is prepared by adding damping material into lightweight concrete, and the damping material is mixed with one or more of polyvinyl alcohol, polypropylene emulsion, and styrene-butadiene latex, and the volume percentage thereof is 20-30%.

[0010] Furthermore, the explosion-proof polymer coating adopts polymer paint, and the polymer paint preferably adopts styrene acrylic emulsion, and the content of styrene acrylic emulsion is 40-60%.

[0011] Furthermore, the explosion-proof fiber concrete is made by adding explosion-proof fibers into lightweight concrete. The explosion-proof fibers are preferably mixed with explosion-proof steel fibers, explosion-proof polypropylene fibers and explosion-proof carbon fibers.

[0012] Furthermore, the arched surfaces of the outer arched steel plate units all face outwards, and the concave surfaces of the outer arched steel plate units all face one side of the high-strength fixed hinge.

[0013] The beneficial effects of the present invention are that the explosion-proof wall structure has strong crack resistance and explosion-proof ability, and strong shock absorption and coordinated energy consumption ability. In order to enable the explosion-proof wall to fully dissipate the impact force of the explosion, the impact force acts on the explosion-proof fiber concrete, and the energy is transferred to the energy-absorbing and shock-absorbing layer and the outer arch-type connected energy-consuming steel plate. With the help of high-strength fixed hinges and ordinary fixed hinges, the energy-consuming extrusion support steel plate fan and the energy-consuming support connection steel plate are deformed and energy is consumed through elastic support connecting rods and elastic force transmission connecting rods. At the same time, the concrete filled with damping material extrude and consumes energy. Fixed hinges and elastic connecting rods are set to ensure that the coordinated connection performance of the energy-consuming steel plate fan is good, and the impact force of the explosion is dispersed and conducted, which can significantly improve the energy consumption efficiency. The impact force is buffered in multiple layers through the coordination of the structure itself. At the same time, the supporting effect of multiple energy-consuming extrusion support steel plate fans makes the overall structure have explosion-proof shock absorption and buffering energy consumption while having sufficient strength, which can reduce the harm caused by the explosion to the personnel and objects on the protection side.
