Specific embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit scope of the present utility model.
As shown in figure 1, one kind of the present embodiment is double to open fire resistant doorsets, including the first door leaf 1, the second door leaf 2 and doorframe 3, the
The side of one door leaf 1 is the first connecting side, and one end of the first connecting side and doorframe 3 rotates connection, and the side of the second door leaf 2 is the
The opposite side of two connecting sides, the second connecting side and doorframe 3 rotates connection, it is double open fire resistant doorsets and close when, the first door leaf 1 away from
, away from side laminating in doorframe 3 of the second connecting side, the outside of doorframe 3 can be with for the side of the first connecting side and the second door leaf 2
Wall is fixedly mounted, and also including fireproofing glue strip 4, direction is equipped with the opposite side of the opposite side of the first door leaf 1 and the second door leaf 2
The groove of opposite side depression, fireproofing glue strip 4 is filled in groove.
The groove of the present embodiment is rectangle, and the groove of the first door leaf 1 is by the upper end insertion of the first door leaf 1 to the first door leaf
1 lower end, the groove of the second door leaf 2 by the upper end insertion of the second door leaf 2 to the lower end of the second door leaf 2, the shape of fireproofing glue strip 4 and groove
Shape structure matches, and fireproofing glue strip 4 thickness more than or equal to groove depth, fireproofing glue strip 4 pass through adhesive sticker and groove
Inwall is fixedly mounted, and adequately fills up whole recess region, and fireproofing glue strip 4 is generally made of expanded graphite, PVC materials, when
The first door leaf 1 is heated with the fireproofing glue strip 4 of the second door leaf 2 and expands when there is fire, blocks the first door leaf 1 and the second door leaf
Gap between 2, intercepts the air circulation between two spaces, is effectively prevented fire early stage dense smoke, toxic gas and heat
Gas is to the harm of human body and controls fire spreading.
First door leaf 1 and the second door leaf 2 of the present embodiment include being surrounded by the first door-plate 5, the second door-plate 6 and biside plate
Door body and the packing material in door body, the first door-plate 5 and the second door-plate 6 generally using steel door-plate, steel Wooden door plank or
Wooden door-plate, packing material is the fire-proof heat-insulating material nontoxic to human body, and the first door-plate 5 is located at the outside of the second door-plate 6,
Door body is outward extended with bead structure 7, the integrally connected of 7 and second door-plate of bead structure 6, first from the side away from connecting side
One side of plate 5 is located in bead structure 7 and installation chimeric with bead structure 7, and groove is arranged on the first door-plate 5, first
The bead structure 7 of fan 1 is centrosymmetric with the bead structure 7 of the second door leaf 2, respectively positioned at the first door leaf 1 and the institute of the second door leaf 2
Constitute the both sides of plane.It is double open fire resistant doorsets close when, the bead structure 7 of the first door leaf 1 is overlapped on first of the second door leaf 2
The outside of plate 5, the bead structure 7 of the second door leaf 2 is overlapped on the outside of the first door-plate 5 of the first door leaf 1.
The present embodiment it is double open fire resistant doorsets be mainly used in closing escape stair, lead to aisle, closing escalator, cable shaft,
The inspection door of the vertical duct well such as piping shaft, smokejack, garbage chute, can be used as gate inhibition's fire resistant doorsets, indoor fire-prevention door, anti-explosion fire
Door, quick lock fire resistant doorsets, chance fire are quickly opened fire resistant doorsets and are used.
A kind of double operation principles for opening fire resistant doorsets of the present embodiment：Fireproofing glue strip 4 is more soft under normal temperature state, is adapted to
Install；When there is fire in double sides for opening fire resistant doorsets, because gas flow temperature is raised, the fire prevention of the first door leaf 1 and the second door leaf 2
Adhesive tape 4 is heated and is expanded, and can rapidly fill the gap between the first door leaf 1 and the second door leaf 2, can play prevention heat
The outer effect dissipated with flue gas diffusion, and within a certain period of time, with fire stability higher, integrality and thermal insulation.
