Description

A kind of dual peacetime assembled dismountable steel structure system
Technical field
The present invention relates to structural engineering fields.
Background technique
In recent years, because the various explosion accidents in wartime bombing, terrorism explosive attack, production and life lead to house Collapse and cause the event of casualties and property loss too numerous to enumerate, has seriously affected social stability and national security, it is more right The public causes psychological huge wound.In times of crisis, building not only cannot provide protection to people, instead can personnel Cause more serious injury.Therefore, it needs to bring into the explosion-proof capabilities of building structure design when Architectural Structure Design to consider Factor in.
Anti-explosion wall is a kind of critical facility of protection explosion air-shock wave, and it is lateral that when design covers shock wave bring Impact load outside wall face, but wall steel using amount is larger at present, lateral arrangement of reinforcement is complex, is easy to the drawbacks of cracking and needs to be solved Certainly.
Double steel plate-concrete combined structure is the steel plate disposed inboard by being composed of double-layer plate and concrete filled The shear connectors such as peg guarantee the co-operation with concrete.This kind of encased steel plate can effectively prevent concrete cracking, inside fill out Concrete can provide steel plate out of plane constraint effect, and overall structure have many advantages, such as bearing capacity height, good leak tightness, easy for construction, There is application in engineering fields such as building core cylinder, mine tunnel, offshore structures.
Summary of the invention
To combine war of resistance protection requirements and routine use demand, the invention proposes a kind of dual peacetime assembled is detachable Steel structure system has the advantages such as protective performance is excellent, assembled construction construction is convenient, can be widely applied to low-rise building work Journey.
Technical scheme is as follows:
A kind of dual peacetime assembled dismountable steel structure system, the component and material which uses include the double steel of dome Plate-concrete combined structure unit, middle cylinder double steel plate-concrete combined structure unit, lower shell double steel plate-concrete Composite structure unit, light gauge cold-formed steel shape skeleton, composite interior wallboard, compound external wall panel, assembled floor, angle cleat, bolt, Vertical high-strength steel sealing plate, horizontal high-strength steel sealing plate, high-strength interior steel plate, high-strength outer steel plate, vertical high-strength steel connecting plate, level are high-strength Steel connecting plate, high-strength steel ribs, ultra-high performance concrete, peg, tapping screw.It is the vertical high-strength steel sealing plate, horizontal high Strong steel sealing plate, high-strength interior steel plate, high-strength outer steel plate, vertical high-strength steel connecting plate, horizontal high-strength steel connecting plate, high-strength steel ribs exist Factory is welded to each other, and ultra-high performance concrete is perfused in intermediate space and completes to conserve, is respectively formed dome double steel plate-coagulation Structural unit, middle cylinder double steel plate-concrete combined structure unit and ground lower shell double steel plate-Combined concrete knot close in local soil type Structure unit;Dome double steel plate-concrete combined structure the unit mutually splices closure using bolt, forms the circle of protection cylinder Top part;Middle cylinder double steel plate-concrete combined structure the unit mutually splices closure using bolt, forms protection cylinder Middle cylinder part;The ground lower shell double steel plate-concrete combined structure unit mutually splices closure, shape using bolt At the underground shell portion of protection cylinder;The protection cylinder is made of dome, middle cylinder and ground lower shell three parts, uses spiral shell It tethers the flat high-strength steel connecting plate of water receiving and forms entirety;The light gauge cold-formed steel shape skeleton and middle cylinder double steel plate-concrete The angle cleat welded on composite structure unit is bolted, remaining light gauge cold-formed steel shape skeleton is mutually interconnected by bolt It connects;The composite interior wallboard, compound external wall panel are connect by tapping screw with light gauge cold-formed steel shape skeleton, formation cold bending thin wall Combined wall;The assembled floor is laid on cold bending thin wall combined wall, completes single layer structure construction;The single layer Structure repeats to construct, until overall structure is completed.
The present invention has the advantages that compared with the existing technology
(1) war of resistance protection use demand can be had both in the new structural systen and routine use demand, surrounding clod wash are thin Wall combined wall can be according to daily building function use demand design arrangement, and intermediate protection cylinder is firm in structure, Ke Yiman Sufficient wartime bombs requirement of shelter, while the space as vertical traffic function arrangement.
(2) protection cylinder is adopted as cylinder and adds domed form, is conducive to shock wave energy to spreading around protection cylinder;Protection Cylinder is divided into part of partially taking refuge with underground of taking refuge on the ground, and space utilization rate increases;Protect cylinder strong using high strength steel plate-superelevation The high assembled wall of concrete, peg can reinforce the compound action of two kinds of materials, so that steel and concrete give full play to respectively Materials with High Strength performance has the advantages that bearing capacity high rigidity is big.
(3) for single layer structure unit, the arrangement of intervening guard cylinder and surrounding cold bending thin wall combined wall be may be implemented Multiple seismic-proof, intervening guard cylinder rigidity is big, as the first line of defence provided fortification against earthquakes, surrounding cold bending thin wall combined wall As second defence line, excellent earthquake resistance.
(4) three parts of middle cylinder are to be bolted closure by double steel plate-concrete combined structure unit use to spell Dress composition, can be according to transport and on-site hoisting capacity of equipment partition structure cell size;Double steel plate-concrete combined structure list First prefabrication, the available high standard control of quality;Overall structure all realizes prefabrication, and the construction of assembled in situ formula is built Efficiency is made to greatly improve;It is bolted so that double steel plate-concrete combined structure unit is detachably re-mounted and used, turnover effect Rate is high.
This kind of dual peacetime assembled dismountable steel structure system can meet simultaneously the war of resistance protection high-bearing capacity demand and Daily building function use demand, structural seismic performance is excellent, prefabricated assembled construction, and efficiency of construction is high, what is had a large capacity and a wide range It has broad application prospects in civilian low-rise building structure.
