Description
Technical field
The invention belongs to the construction safety field, be specially the explosion-proof wall of the embedded steel frame concrete of a kind of novel assembled, be adapted at using before important public and civil building.
Background technology
The destabilizing factors such as religion, national conflict, economic conflict, territoril disputes are roots that all kinds of terrorist incidents occur.According to relevant statistics, the attack of terrorism of implementing in the blast mode in recent years is in rising trend, and every year on average 300 left and right, and scale is increasing with impact.Simultaneously, explosive terror attack mainly occurs in the intensive public place of personnel, and its type of raid is mainly car bomb and suicide blast etc.Therefore, adopt the engineering counterterrorism measure can significantly reduce the harm that the attack of terrorism brings, important building considers that counterterrorism measure is numerous engineers and technicians' common recognition when protection.
At present, construction safety has masonry blast wall, steel concrete blast wall, steel plate sand combination blast wall and blast wall with multiplayer composite structure with blast wall.Masonry blast wall and the steel concrete blast wall capability of antidetonance are poor, and thickness of wall body is larger, a little less than especially big explosion wave load resistivity.Steel plate sand combination blast wall and blast wall with multiplayer composite structure have the energy dissipating effect, but the body of wall bending rigidity is little, and resistance to overturning is poor, and cost is higher.
Summary of the invention
The object of the invention is to overcome the defects such as existing blast wall cost of investment is high, integral rigidity is low, the antiknock ability is weak, inherit the explosion-proof advantages such as its energy dissipating energy dissipation capacity is strong simultaneously, propose the explosion-proof wall of a kind of embedded steel frame concrete.
Concrete technical scheme of the present invention is: the explosion-proof wall of a kind of embedded steel frame concrete, comprise body of wall and with the integrated poured concrete basis of body of wall, be embedded with the steel frame be integrally formed in body of wall and basis, it is characterized in that: steel frame consists of the column on both sides, many crossbeams, basic embedded iron parts, every crossbeam two ends by different elevations respectively level be fixedly connected on the column that is positioned at both sides, wherein:
A, column adopt H shaped steel, and H shaped steel consists of with the H shape steel web that is connected two H section steel flanges the H section steel flange of both sides, and H section steel flange face is consistent with the body of wall length direction;
B, crossbeam adopt T-steel, T-steel consists of with the T-steel web that is connected the two T-steel edges of a wing the T-steel edge of a wing of both sides, and crossbeam is divided into a foundation crossbeam in bottom, at head piece and the many intermediate transverse girders between cross member and head piece at top, upwards, the T-steel web of head piece is downward for the T-steel web of cross member;
The embedded iron parts on c, basis is fixedly connected on below cross member;
Have a plurality of screw holes on the T-steel edge of a wing of d, every crossbeam, and the screw hole on every crossbeam and screw hole on other crossbeam are organized screw holes corresponding formations mutually, be installed with screw rod in every group of screw hole, the screw rod top is fixedly connected on head piece, and the screw rod bottom is fixedly connected on embedded iron parts;
E, H shape steel web upwards have draw-in groove in the middle of bottom, and the T-steel web two ends of cross member are embedded in respectively in corresponding draw-in groove.Like this, can make the H shape steel web be connected with cross member tightr.
Being fixedly connected with described in the present invention can be welding, and the connected modes commonly used such as screw (bolt) connection, can increase in case of necessity angle bar and make connection assist.Embedded iron parts also can be built in earlier stage with basis.
Further scheme is: the screw rod upper end is connected on head piece by spiro rod cap, and embedded iron parts is provided with corresponding screw hole, and the screw rod lower end is fixedly connected on embedded iron parts by this screw hole.Like this, can make steel frame there is certain prestressing force before fluid concrete, be conducive to strengthen the mechanical property of blast wall.
Further scheme is: the embedded iron parts two ends are fixed with downward ground anchor bolt.Particularly, when basis is more much larger than wall size, ground anchor bolt can play the effect of reinforcing rib.
This blast wall is to set up the built-in steel framework in concrete wall, has solved the shortcomings such as in the explosion-proof wall of concrete, resistance to overturning is poor under Blast Load, bending rigidity is low, meets blast wall conceptual design requirement simultaneously, " consumption ", " every ", " soon "." consumption " is mainly reflected in blast wall can absorb a large amount of explosion energies by METHOD FOR LARGE DEFORMATION ELASTOPLASTIC, alleviates the damage effect of shock wave to wall rear protecting target." every " be mainly reflected in blast wall can be for wall after target play certain shielding effect, prevent that car bomb etc. from approaching the target blast." soon " is mainly reflected in embedded steel frame element precast, assembling construction, operation is simple, the duration is shorter.
The steel frame various piece can be in factory process, and on-the-spot bolt, screw rod, ground anchor bolt and the angle steel used assembled or the employing welding manner, or assembling combines with welding.
With original blast wall, compare, the present invention has the following advantages:
1, steel frame central post, crossbeam, screw rod, angle steel, embedded iron parts etc. are all manufactured in factory, and processing technology is simple, standardization level is high, cost is low, speed of application is fast, can be in the moulding of particular time rapid-assembling.
2, power transmission is clear and definite, framework inner prop and crossbeam, crossbeam and screw rod, between framework and concrete collaborative work reliable, whole bending rigidity is large, resists instantaneous explosion effect ability strong, can resist large equivalent car bombing.
3, simple in structure, the stable performance of the present invention, the scope of application is wide, is applicable to the outside antiknock protection of all kinds of public and civil buildings such as school, airport, government offices building.
4, working procedure variation of the present invention.During construction, both can first water underpin and embedded iron parts, then assemble steel frame, finally build outside concrete; Also steel frame can be fixed in foundation ditch to then monobloc cast moulding.
5, body of wall of the present invention is fixed good with basis.Cross member is combined with embedded iron parts better, and ground anchor bolt can further be strengthened wall and be connected with basis.
6, H shaped steel, the T-steel in the present invention be a kind of section area distribute more optimize, the ratio of strength to weight more rationally, the economic section high efficiency section bar that all there is stronger bending resistance on all directions.The resistance to overturning of opposing explosion wave is better than the steel concrete blast wall of same cross-sectional steel content.
7, screw rod of the present invention has not only increased the steel ratio of wall section, has also improved the resistance to overturning of steel frame, and the screw thread on screw rod can increase and concrete interlock degree.
8, main bearing member of the present invention is steel, and after body of wall lost efficacy, the steel recovery utilization rate is high.
9, cost performance of the present invention is higher, and construction and maintenance cost are lower.
