Abstract
The utility model relates to a wall, in particular to an anti-explosion wall combined by concrete and a steel plate. Two layers of two-way Class III reinforcements are configured in the anti-explosion wall; an anti-explosion steel plate is added in the middle of a concrete wall body; toggle pins are arranged on the both sides of the anti-explosion plate quincuncially; the anti-explosion plate is fixed in concrete; and the periphery of the anti-explosion steel plate is securely welded with steel channel embedded parts on concrete columns or beams of a body structure. The anti-explosion wall adopts 500mm thick reinforced concrete. The transverse reinforcements are made of Class III steel which is 20mm in diameter, and the distance is 150mm. The longitudinal reinforcements are made of Class III steel which is 22mm in diameter, and the distance is 150mm. The 20mm thick anti-explosion steel plate is arranged in the middle of the concrete wall of the anti-explosion wall, and the double-faced toggle pins are arranged on the two sides of the anti-explosion plate, and are 45mm in length. A first barrier of the concrete anti-explosion wall is impacted and destroyed, and the toughness of the anti-explosion steel plate serves as a second barrier to decrease an impact force of an impact wave, so that damages to a building and injuries of operators due to explosion are reduced, and the safety of workers and equipment is protected.
Description
Technical field
The utility model relates to a kind of wall, particularly relates to a kind of antiknock wall by concrete and steel plate combination.
Background technology
Blast is material chemistry or physical change process rapidly, in change procedure, promptly emit huge heat and generate a large amount of gas, the gas of this moment since moment remain and be in the limited space, so great pressure is arranged, object around the demolition point is produced strong pressure, when gases at high pressure expand rapidly, formed blast.
Blast wall refers to the stronger wall of anti-blast pressure, also claims anti-quick-fried wall, antiknock wall.Be located in the factory building or warehouse of explosion danger more.Explosion-proof brick wall: only be used for less factory building and the warehouse of explosive substance.Explosion-proof steel concrete wall: desirable blast wall.Structure: thickness should not mostly be 500mm, 800mm less than 200mm, even 1m; Concrete strength is not less than C20; Reinforcing bar is by structural calculation, but is not less than concrete strength grade.Explosion-proof steel plate wall: be skeleton with the channel-section steel, steel plate and skeleton riveted joint or weld together.
In oil, the chemical industry; because a lot of inflammable and explosive raw materials for production and products are arranged; also to protect surrounding devices and staff's safety in the work; the antiknock wall becomes requisite protection barrier naturally; and a design of antiknock wall and to be applied in the Chemical Engineering Design field be a difficult problem always; the building area of industrial premises is very limited again, can not be designed to the very thick huge blast electuary ripple of concrete wall opposing, makes the intensity of existing antiknock body of wall be difficult to satisfy safety requirements.Only use steel antiknock wall can make that again construction cost significantly improves, general enterprise is beyond affordability.
Summary of the invention
The purpose of this utility model is to provide a kind of antiknock wall by concrete and steel plate combination.This antiknock wall is composited with concrete and steel; make the concrete antiknock wall first road barrier destruction that is hit; be the impact force that two road barriers reduce shock wave with antiknock steel plate toughness, to reduce blast to building and operating personnel's injury, the safety of protection staff and equipment.
The purpose of this utility model is achieved through the following technical solutions:
A kind of antiknock wall by concrete and steel plate combination, configuration double-layer double-direction grade III steel muscle in the described antiknock wall, add one deck steel antiknock plate in the middle of the concrete wall, antiknock plate two sides quincuncial arrangement peg, be fixed in the concrete, firmly weld with the concrete column of agent structure or the channel-section steel embedded part on the beam around the steel antiknock plate.
Described a kind of antiknock wall by concrete and steel plate combination, described antiknock wall adopts the thick armored concrete of 500mm.
Described a kind of antiknock wall by concrete and steel plate combination, described antiknock wall arrangement of reinforcement is: laterally arrangement of reinforcement is diameter 20mm grade III steel, spacing 150mm.Longitudinal reinforcement is diameter 22mm grade III steel, spacing 150mm.
Described a kind of antiknock wall by concrete and steel plate combination is equipped with the thick steel antiknock of 20mm plate in the middle of the concrete wall of described antiknock wall, and antiknock plate both sides are equipped with two-sided peg, the long 45mm of peg.
Advantage of the present utility model and effect are:
1. the utility model is concrete and steel antiknock board combining structure, take full advantage of the toughness of steel antiknock plate, utilize the rigidity of armored concrete antiknock wall, both actings in conjunction, alleviate the pressure of explosion wave largely, namely reduce the thickness of body of wall, increased the utilized area of factory building, reduced construction cost simultaneously again.
2. the steel antiknock plate of veneer does not have the antiknock function, but utilizes the toughness of steel antiknock plate after concrete wall are combined, and can effectively reduce the flashy load that blast produces by the utmost point, is replenished for the concrete deficiency of fragility.Effectively prevent from exploding the pressure that produces to the injury of the person and equipment, also having prevented that fragment that blast produces is to the injury of the person simultaneously.

The utility model Fig. 2 is antiknock wall horizontal steel bar figure;
The utility model Fig. 3 is antiknock wall peg arrangement diagram.
The specific embodiment
Be elaborated below in conjunction with the utility model of embodiment.
The utility model technology is mainly used in oil, chemical plant installations has factory building or the storehouse that first and second classifications have explosion hazard area.
The utility model is main member with the armored concrete body of wall, configuration double-layer double-direction grade III steel muscle (specifically according to calculating gained) in the concrete wall, and wall structure: thickness should not mostly be 500mm, 800mm less than 400mm, even 1m; Concrete strength is not less than C30.Add one deck steel antiknock plate in the middle of the concrete wall, the thickness of antiknock plate is selected according to the blast situation of different brackets, structure also must not be less than 6mm, antiknock plate two sides quincuncial arrangement peg, in order to be fixed in the concrete, concrete column or the channel-section steel embedded part 6 on the beam 7 with agent structure around the steel antiknock plate firmly weld, and make the antiknock plate form firm steel plate flexible barrier one in concrete wall.
Embodiment: adopt the thick armored concrete antiknock wall 2 of 500mm, arrangement of reinforcement is: laterally arrangement of reinforcement 4 is diameter 20mm grade III steel, spacing 150mm.Longitudinal reinforcement 3 is diameter 22mm grade III steel, spacing 150mm.Be equipped with the thick steel antiknock of 20mm plate 1 in the middle of the concrete wall, antiknock plate both sides are equipped with two-sided peg 5, the long 45mm of peg.Steel antiknock plate closely is combined with concrete wall.
