Description

A kind of manufacture method of steel special type explosion proof door
Technical field
The present invention relates to the processing method of a kind of, and in particular to a kind of manufacture method of steel special type explosion proof door.
Background technology
Steel explosion proof door is usually used in the inflammable and explosive building such as Chemical Industry Park, building, is installed on security performance higher Or during the building for having requirement of explosion proof is imported and exported.When interior of building or outside generation explosion time, door can be produced effectively to blast protection Shock wave.Explosion proof door is opened flat, translates two kinds of patterns, and opening direction determines according to blast position or escape direction.Existing skill Explosion proof door in art generally only sets built-in fitting in explosion proof door bottom, when mounted, by the underground of built-in fitting embedment door body bottom In, although this pre-buried mode is simple, when there is explosion time, the steadiness and anti-impact force of its door body are excessively poor, so Generation explosion time, many explosion proof doors are all that top is closed down at first, or even are impacted away.
The content of the invention
It is an object of the invention to provide a kind of manufacture method of steel special type explosion proof door, existing explosion proof door anti-impact is solved Hit that power is poor and problem of steadiness of wall difference.
The present invention is achieved through the following technical solutions：
A kind of manufacture method of steel special type explosion proof door, including base plate, the base plate is a groove, also including facing Plate, doorframe, the base plate, decoration panel, doorframe are made of carbon steel, are comprised the following steps：
A：N thickness carbon fiber board and M floor height intensity PE nonwoven stitching floor cloth are set in groove, N, M be >=1 it is just whole Number, the thick carbon fiber board and high intensity PE nonwoven stitching floor cloth interval settings；
B：After step A completions, decoration panel is covered on base plate, be compacted decoration panel and base plate using trigger squeeze, so The connector of decoration panel and base plate is carried out by edge sealing using carbon steel plate afterwards, door leaf is completed and is made；
C：A circle reinforcing rod, inner side surrounding are uniformly arranged in the outside surrounding of doorframe uniformly fix a circle fire seal, Doorframe is completed to make；
D：After door leaf and doorframe are linked together, the anticorrosive coat on door leaf and door frame surface spraying.
Further, explosion proof door of the prior art generally only sets built-in fitting in explosion proof door bottom, when mounted, will be pre- In the underground of embedded part embedment door body bottom, although this pre-buried mode is simple, when generation explosion time, the setting of its built-in fitting Direction is single, and explosion-proof door body is very uneven with the reverse resistance of impulsive force in wall surrounding, makes the steadiness of door body very Difference, so there is explosion time, many explosion proof doors are all that top is closed down at first, or even are impacted away.The present invention is directed to problem above, One is set in the explosion proof door outer frame side of steel and enclose reinforcing rod, during installation, according to the length with reinforcing rod and position, in wall Surrounding is beaten and reinforcing rod quantity, the hole of location matches, and then reinforcing rod is slowly inserted wall surrounding, after insertion is completed, will Reinforcing rod is poured with the gap of wall surrounding using the cement of high density, and after completion is poured, is fixed in cement surface Upper steel plate, the steel plate extension is attached on the wall on periphery, sprays anticorrosive coat again on steel plate.In addition, the present invention is by thick carbon Fiberboard and high intensity PE nonwoven stitching floor cloth are disposed in the base plate of groove type, and this spaced mode is compared Prior art only sets one layer of fire prevention filler, and the door leaf anti-impact force for so completing is more preferable.Fire seal is used for will Gap sealing between doorframe and door leaf, it is ensured that the sealing of explosion proof door.Existing explosion proof door shock resistance is solved with upper type Power is poor and problem of steadiness of wall difference.
The thickness of the base plate is 5mm~20mm.The thickness of base plate is arranged between 5mm~20mm, it is explosion-proof to ensure The impact resistance and resistance to fire intensity of door.
The thickness of the fire seal is 1660mm~3255mm.Be able to will be prevented according to the gap between explosion proof door and doorframe The thickness of fiery sealing gasket is arranged between 1660mm~3255mm, both ensure that sealing, turn avoid the bad switch of explosion proof door Problem.
The present invention compared with prior art, has the following advantages and advantages：
A kind of manufacture method of steel special type explosion proof door of the present invention, including base plate, the base plate is a groove, is also included Decoration panel, doorframe, the base plate, decoration panel, doorframe are made of carbon steel, and N thickness carbon fiber board and M are set in groove Floor height intensity PE nonwoven stitching floor cloth, N, M be >=1 positive integer, the thick carbon fiber board and high intensity PE nonwoven stitching floors Cloth interval setting, decoration panel is then covered on base plate and is uniformly arranged a circle reinforcing rod, inner side surrounding in the outside surrounding of doorframe A circle fire seal uniformly is fixed, it is poor and wall firm by with upper type solving existing explosion proof door anti-impact force Property difference problem.
Specific embodiment
To make the object, technical solutions and advantages of the present invention become more apparent, with reference to embodiment, the present invention is made Further to describe in detail, exemplary embodiment of the invention and its explanation are only used for explaining the present invention, are not intended as to this The restriction of invention.
Embodiment
A kind of manufacture method of steel special type explosion proof door of the present invention, including base plate, the base plate is a groove, is also included Decoration panel, doorframe, the base plate, decoration panel, doorframe are made of carbon steel, are comprised the following steps：A：N is set in groove Thickness carbon fiber board and M floor height intensity PE nonwoven stitching floor cloth, N, M be >=1 positive integer, the thick carbon fiber board and high-strength Degree PE nonwoven stitching floor cloth interval settings；B：After step A completions, decoration panel is covered on base plate, will be adornd using trigger squeeze Panel is compacted with base plate, and the connector of decoration panel and base plate then is carried out into edge sealing using carbon steel plate, is completed door leaf and is made；C： A circle reinforcing rod, inner side surrounding are uniformly arranged in the outside surrounding of doorframe and uniformly fix a circle fire seal, complete doorframe system Make；D：After door leaf and doorframe are linked together, the anticorrosive coat on door leaf and door frame surface spraying.The thickness of the base plate is 10mm.The thickness of the fire seal is 2000mm；By with upper type solve existing explosion proof door anti-impact force it is poor and The problem of the steadiness difference of wall.
Above-described specific embodiment, has been carried out further to the purpose of the present invention, technical scheme and beneficial effect Describe in detail, should be understood that and the foregoing is only specific embodiment of the invention, be not intended to limit the present invention Protection domain, all any modification, equivalent substitution and improvements within the spirit and principles in the present invention, done etc. all should include Within protection scope of the present invention.
