Special die for blockage and air ventilation type explosion-proof and fireproof plate

Abstract

The invention provides a special die for a blockage and air ventilation type explosion-proof and fireproof plate, and belongs to the field of disaster prevention of projects. An one-piece die cover isa rectangular cylinder, and two rows of cavity die covers are vertically arranged in the one-piece die cover; butting type blockage buffer port die covers are vertically and uniformly distributed atthe corresponding sides of the interior of each cavity die cover; anti-disengaging circular plates are arranged at the inner side of each cavity die cover and the crossing part of each cavity die cover and the corresponding butting type blockage buffer port die cover. The special die has the beneficial effect that the production technology is simple and quick. The produced blockage and air ventilation type explosion-proof and fireproof plate has the advantages that the fireproof property is good, the stress property is good, the installation is convenient, the replacement is easy, and the installation is quick, simple and convenient; the surface layer is provided with an obvious pressure-relief vibration-proof port, a fire blockage layer in the middle position has obvious buffer and fire blockage double functions, the explosion-proof and fireproof properties are obviously improved, and the personal casualty and the economic loss are effectively reduced when a fire accident occurs on anunderground structure.

Description

technical field [0001] The invention relates to the field of engineering disaster prevention, and specifically relates to a special mold for partitioning and ventilating explosion-proof and fireproof boards. Background technique [0002] In recent years, underground structures have developed rapidly in our country, and many subways and underground complexes have been built one after another. However, the fire prevention of underground structures has always been an insurmountable difficulty for underground structures. [0003] At present, fire retardant coatings are widely used, but the thickness and thermal conductivity of fire retardant coatings are limited, so they cannot play an effective role at all. [0004] In addition, fires in underground spaces are often accompanied by explosions. Due to the narrow space, the energy cannot be released, which doubles the destructive power of the explosion, so special attention should be paid. Contents of the invention [0005] In ...
