Abstract

The invention discloses a staggered splicing type steel plate-RPC anti-detonation door and a construction method thereof. According to the anti-detonation door, a cavity formed by a door leaf front side steel plate, a door leaf reverse side steel plate and a plurality of inner ribbed beams is filled with an RPC inner core. The construction method of the anti-detonation door comprises the steps that firstly, the door leaf front side steel plate, the door leaf reverse side steel plate and the inner ribbed beams are manufactured according to the size; secondly, the number of needed steel bars is calculated; thirdly, steel bar holes are formed in the inner ribbed beams in the length direction; fourthly, the door leaf front side steel plate is welded to the odd-number inner ribbed beams, and the door leaf reverse side steel plate is welded to the even-number inner ribbed beams; fifthly, the door leaf front side steel plate and the door leaf reverse side steel plate are spliced in a staggered manner, and the steel bars penetrate the steel bar holes; sixthly, reactive powder concrete is poured in the cavity formed by the door leaf front side steel plate, the door leaf reverse side steel plate and the multiple inner ribbed beams and is standing for 48 h; seventhly, the anti-detonation door is conveyed into a steam curing room at the temperature of 90 DEG C to be cured for 72 h; and eighthly, after 28 days, the RPC and the steel plates are effectively bonded to form the steel plate-RPC anti-detonation door. The staggered splicing type steel plate-RPC anti-detonation door and the construction method thereof are applied to anti-detonation protection projects.

Description

technical field [0001] The invention relates to an anti-blast door, in particular to a construction method for a cross-assembled steel plate-reactive powder concrete (RPC) anti-blast door. Background technique [0002] Explosion accidents occur from time to time, such as the explosion accident in Tianjin Binhai New Area in 2015, which had a huge impact and suffered heavy losses. Setting up anti-blast doors is an anti-blast protection method to effectively prevent the spread of explosion hazards. At present, the common anti-explosion door in the market is the beam-plate type steel anti-explosion door. There is a cavity inside the anti-explosion door. Plate steel anti-blast doors and other combined anti-blast doors have many welds, the welding construction space is narrow, and the quality of welds is difficult to guarantee. Under the action of explosion load, the welds are easy to be damaged before the steel plate, which is the weak link of blast-resistant doors; Therefore, ...
