Description
Technical field
The present invention relates to civil buildings explosion protection technical field, more particularly to a kind of novel blast wall.
Background technology
Blast wall is the important feature form for protecting military applications and important civil buildings to resist explosive attack, main flow it is anti-
Quick-fried wall design relies primarily on the intensity, ductility and energy absorption of structure to resist explosive load.Domestic and foreign scholars exist to blast wall
Response and explosion-proof effect under explosive load, have carried out numerous studies.As Hulton and Gough proposes that steel-concrete-steel is explosion-proof
Wall, the two blocks of steel plates separated by friction welding pin are constituted, integral thickness up to 210mm to 740mm, internal fill concrete with
Force of inertia power is provided；On lot of experiments Research foundation, Coyle and Cormie etc. give steel-concrete-steel blast wall
Detailed design guide and design example.With the development of new material, increasing researcher begins to focus on lightweight explosion wall
Exploitation or utilize Energy dissipating material dissipation Explosive Energy, such as Ye and Ma have studied in the explosion-proof of the preceding surface additional foam aluminium lamination of blast wall
Technology, research finds that in the case where foam extra play is reasonable in design the capability of antidetonance of structure will significantly be strengthened.However,
Research is it has also been found that the validity of the technology depends on the spy of the reasonable design, the characteristic of foamed material and explosive load of froth bed
Levy.Scholars' also interim blast wall of research and development, such as Scherbatiuk and Rattanawangcharoen banket anti-
Protect explosive test and the numerical simulation of unit；Rice etc. have studied the effective of masonry-sand-masonry blast wall resistance explosive load
Property；Etc. the validity that the aluminium sheet that have studied filling sandstone resists explosive load.
Although developing a variety of blast walls with new material and new structure in recent years, the design reason of blast wall
Thought is still based primarily upon traditional structural strength, ductility and energy absorption concept.It is reasonable in design on these conceptual foundations to prevent
Quick-fried wall can weaken explosive load but also have intrinsic deficiency.For example, non-reinforced masonry blast wall and armored concrete blast wall are once
Destroyed by explosive load, the fragment of generation will cause great threat to the personnel after blast wall and structure.Steel-concrete-steel
Blast wall resists explosive load using high-strength steel and big mass charge concrete, and steel facing provides initial resistive force to explosive load
And constrain fill concrete, fill concrete provides explosive load inertia drag, such design often enormous size and into
This costliness.On the other hand, blast wall light weight can be made and be effective against by explosion energy being absorbed using flexible material such as foam
Explosive load；But the performance of foamed material is very unstable is difficult to control to, and foamed material absorbs the efficiency of explosion energy not
But depending on foamed material characteristic and depending on its interaction with explosive load.At the same time, due to this blast wall
Large plastometric set based on structural material absorbs explosion energy, and the ability that resistance repeats explosive force is poor.These characteristics cause
Foamed material is difficult the blast wall for being designed to high-efficiency and economic.In addition, it is contemplated that urban planning needs and soil limitation, most of anti-
Quick-fried wall is bulky and is not suitable for building in urban area.
The content of the invention
The purpose of the present invention is to overcome that of the prior art not enough there is provided a kind of new type explosion proof suitable for urban area
Wall, handsome in appearance, structure is slim and graceful, and antiknock protection effect is good, and can greatly save material and construction cost.
The technical solution adopted in the present invention is：A kind of novel blast wall, including at least row's structural column layer, and for inciting somebody to action
The ground anchor that the structural column layer is fixed on the ground；The structural column layer is equidistantly equal by several structural column monomers
It is even to rearrange.
The ground anchor using the screw thread anchor hole degree of lip-rounding formula being fixed in ground, the screw thread anchor hole mouthful and
The structural column monomer is corresponded；The bottom of the every structural column monomer is provided with to match with the screw thread anchor hole mouthful
The screw thread of conjunction.
The ground anchor uses UNICOM's track of geometric matrix form, and UNICOM's track is by some phases in length and breadth
The track monomer of friendship is constituted；The track monomer is bathtub construction, and its two flange plates upper surface is respectively arranged with and the structure
The inside flanging that post monomer is engaged.
The bottom of the structural column monomer is arranged with the sleeve being connected with the track monomer, the set by neck
Cylinder bottom is provided with bottom plate, and the lower surface of the bottom plate is seated in by big roller in the web of the track monomer, the bottom
The outer upper end face of plate is in contact by trundle with the inside flanging of the track monomer.
The bottom of the structural column monomer is connected with pad by neck, and the pad passes through bolt and the track list
The inside flanging of body is fixedly connected；The structural column monomer underrun roller is seated in the web of the track monomer.
The structural column layer is two or more rows, and axle center is used between the structural column monomer of the adjacent structural column layer
Normotopia arrangement mode.
The structural column layer is two or more rows, and axle center is used between the structural column monomer of the adjacent structural column layer
Heterogeneous Permutation mode.
The structural column monomer uses section form for the solid post or cannulated sleeve of circular, square, triangle or rhombus.
The structural column layer is two or more rows, and the structural column monomer of the adjacent structural column layer uses section form
Identical structural column monomer.
The structural column layer is two or more rows, and the structural column monomer of the adjacent structural column layer uses section form
Different structural column monomers.
The beneficial effects of the invention are as follows：Blast wall of the present invention personnel and while structural shielding grade after increase is to wall,
Fragment will not be produced to damage the personnel after blast wall and structure；In addition, blast wall of the present invention is except meeting urban planning
Demand attractive in appearance, can be applied to outside city scope, also with processing, installation, removes easy, can resist the advantages of repetition is exploded,
Material and construction cost can be significantly saved, while being expected to be applied in other kinds of safeguard structure.
