Description
Technical field
The present invention relates to building field, more particularly to a kind of Novel movable assembled blast wall.
Background technology
With the aggravation of the growing tension of international situation, political contradiction, religious contradiction, national conflict etc., attack of terrorism thing
Part increases, fried mainly with car bombing, body bombings and timing currently for the attack of terrorism means of building
Based on bullet attacks.Meanwhile also usually occur the incidents such as chemical plant blast, gas explosion in production and living, these blasts
Destruction of the generation of event to building is very serious, while also results in mass casualties, economic loss.At present, easily meet with
Building to explosive attack is mainly embassy, hospital, school, government building.For these buildings, under explosive attack,
Its periphery sets blast wall, can effectively prevent the destruction exploded to building.
Blast wall can effectively reduce destruction of the blast to building as a kind of anti-explosion product.Current anti-explosion product is mainly
It is divided into two major classes：One kind is fixed blast wall, and the major defect of fixed anti-explosion wall is to recycle difference, constructs cycle length, tears open
Except trouble, the requirement that quick protection need to be carried out for accident can not be met；Another kind of blast wall is that mobile assembled is explosion-proof
Wall, mobile assembled blast wall be mainly characterized by can scene assembled, convenient transport, drillability rate is dismountable to recycle.
Mainly flexible fabric blast wall, mound blast wall, sandbag blast wall, plastics assembled are explosion-proof for mobile assembled blast wall at present
Wall, collapsible blast wall etc..
Application notification number is that a kind of removable fabricated blast wall, the blast wall are mentioned in CN101949184A patent
The novel intelligent material of use, antiknock energy-absorbing effect is good, but material price is high, is not easy to be made, does not possess feasibility.
The explosion-proof wall construction of novel fabricated that the blast wall patent that application notification number is CN101078243A proposes has group
Dress property, but price is higher, and gathering can not be folded.
Apply in the utility model that notification number is CN201801972U, disclose a kind of " movable blast wall ", it is anti-
Quick-fried wall wall is made up of wall core, shear thickening materials layer and protection outer layer, and outside wall core, shearing increases protection outer layer covers
Thick material layer is located between wall core and protection outer layer, and the side lower part of blast wall wall one is provided with fixed support, and the blast wall has
The good capability of antidetonance, but its packing material is expensive.
It is a kind of mobile assembled blast wall that CN103628583A is proposed to apply for notification number, is the anti-of current comparatively perfect
Quick-fried wall, it is directed to the technical essential of mobile assembled blast wall and proposes corresponding technical scheme, the main feature of the blast wall
For mobility, can assemble, antiknock ability it is good, explosion-proof from wall, to internal packing material, to back support structure, front portion is drawn
Bar structure is innovated.But the wall of the blast wall does not realize that wall assembles, and uses more bolt connection, and it is filled
It is comparatively longer with the time.
Just at present, the bursty nature attacked for the terrorist bombings, existing some mobile assembling blast walls are deposited
Difficult in assembling, assembling is not quick enough, and cost is high, and the shortcomings that antiknock ability, gross weight is larger, portable ability, so
How to solve the above problems is those skilled in the art always in the direction of research.
