Abstract
The utility model relates to a fire door, a fire exit door, and a pipe well door, in particular to a door frame and leaf insulating and sealing structure for fire door.. The utility model comprises a frame and a leaf, wherein, the frame and leaf assembly and the frame back are in split structure, with a sandwich layer fixed with bolts and the sides connected and fixed with connecting boards; fireproof seal strips are mounted on the sides of the leaf, a fireproof board fixed to the side boards is arranged in the middle, rib reinforcement is arranged between front and rear boards of the leaf and fixed to the front and rear boards with rivets, and the leaf is hollow and filled with aluminum silicate wool.. Compared to the prior art, a sandwich layer is arranged on the frame in the utility model, and therefore the thermal conduction rate is reduced greatly; the fireproof strips on the sides of the leaf will expand under heat and fill up the gap between the leaf and the frame, and will provide sealing effect even when the door leaf deforms under heat; the fireproof boards are fire retardant and can protect the aluminum silicate wool from damaged; therefore, the door leaf has fire retardant and heat insulating function..
Description
Technical field:
The utility model relates to labeled door, fireproof passage door, pipe well door, especially a kind of frame fan heat-insulating and sealing structure of labeled door.
Background technology:
At present, the most of aluminium silicate wool that adopts of fire-proof door leaf is as fire-proof heat-insulating material, the fire endurance of aluminium silicate wool is about 1000 ℃, and in the aluminium silicate wool of on market, selling usually impurity is arranged, do not satisfy the quality requirement of labeled door, directly fill aluminium silicate wool, do not reach the fire-resistant national standard of door leaf; What fireproof door frame was general is that rolling frame cold drawing folds frame, the frame type is wide at 120～150mm, and the wide fire prevention frame of 120mm can only be fire-resistant 45 minutes, and the wide frame of 150mm can reach fire-resistant more than 50 minutes, basically do not reach national fire-resistant second class 54 minutes, 72 minutes standard-requireds of first class; After frame and the fan assembling one, in fire resistance test, because the door leaf temperature distortion, original one-sided fire proof seal usually can produce the situation that fan and frame break away from, and therefore, in fire prevention, sealing, problem such as heat insulation, is the problem that current labeled door already need solve always.
Summary of the invention:
The purpose of this utility model is intended to solve the problem that present labeled door can not reach fire prevention, heat insulation, sealing function, and a kind of frame fan heat-insulating and sealing structure of labeled door is provided, and makes labeled door meet national labeled door standard, can be by detecting.
Realize that the technical scheme that above-mentioned purpose adopts is: a kind of frame fan heat-insulating and sealing structure of labeled door, comprise framework, fan body, the frame that constitutes framework is the branch body structure with fan combination, frame back side bulk, be provided with intermediate course between the two, and it is fixedly connected to pass this intermediate course by bolt, and both sides connect typing by junction plate; The fire proof seal bar is housed respectively on fan body upper side, left surface, the right flank, be provided with in the middle of the fan body and the fixing PLASTIC LAMINATED of its both sides panel welding, be provided with reinforcing rib between this PLASTIC LAMINATED and the fan body front and back panel, and fixed with it by pulling rivet, the fan body belly shirt is filled with aluminium silicate wool.
Compared with prior art, the utility model framework is provided with intermediate course, greatly reduces heat conduction velocity, has solved fire prevention, heat insulation, the sealing problem of fire prevention frame; The fan body side is provided with fireproofing glue strip and meets thermal expansion, and the slit between fan and the frame is filled, and when fire took place, door leaf produced diastrophic condition, had still played the fire proof seal effect; Cut off into two spaces by PLASTIC LAMINATED in the fan body, when the surface temperature that warms oneself in front of a fire raises, because the partition effect of PLASTIC LAMINATED is arranged, carry on the back the sour aluminum wool of fiery face and the aluminium silicate wool of side towards the fire and produce the tangible temperature difference, therefore carry on the back aluminium silicate wool in the fiery face chamber temperature that do not reach capacity, fibr tissue does not produce damage, has therefore reached the effect of fire-proof and thermal-insulation.
Description of drawings:
Fig. 1 is the utility model framework section structure schematic diagram.
Fig. 2 is the utility model fan body section structure schematic diagram.
The specific embodiment:
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
A kind of frame fan heat-insulating and sealing structure of labeled door, relate to framework and fan body two parts, as shown in Figure 1, framework is made up of frame and fan combination 1, fireproofing glue strip 2, intermediate course 3, frame back side bulk 4, bolt 5, junction plate 6, receptacle material is a cold-reduced sheet, its frame is to divide body structure with fan combination 1 with frame back side bulk 4, is provided with intermediate course 3 between the two, and the material of this intermediate course 3 is a vermiculite board.Frame passes this intermediate course 3 with frame back side bulk 4 by bolt 5 with fan combination 1 fixedlys connected, and both sides connect typing by junction plate 6.
This frame structure is divided into two parts with frame, forms A space and B space.The A space is a side towards the fire, and the B space is for the fiery face of the back of the body, and when fire took place, to the conduction of B space, two spaces were cut off by the intermediate course 3 that vermiculite board constitutes the heat of side towards the fire, filling cement mortar or heat insulating material when installing in two spaces by the A space.So just greatly reduce heat conduction velocity, the fire endurance requirement of the regulation that can be up to state standards with the door leaf joint portion fireproofing glue strip 2, one being installed, is played protection vermiculite board and decoration function; The 2nd, when fire took place, fireproofing glue strip 2 produced and expands, and sealing function is played in the gap of doorframe and door leaf, and fire and flue dust can't pass through, so this frame type structure has solved fire prevention, heat insulation, sealing problem.
As shown in Figure 2, fan body is made up of fire proof seal bar 7, PLASTIC LAMINATED 8, reinforcing rib 9, aluminium silicate wool 10, panel 11, pulling rivet 12, fire proof seal bar 7 is housed respectively on its upper side, left surface, the right flank, be provided with in the middle of the fan body and the fixing PLASTIC LAMINATED 8 of its both sides panel 11 welding, be provided with reinforcing rib 9 between this PLASTIC LAMINATED 8 and the fan body front and back panel 11, and fix with it by pulling rivet 12, the fan body belly shirt is filled with aluminium silicate wool 10, during filling, alumina silicate 10 each binding face are coated with water quality fire prevention glue, and hot pressing is fixed.
Fireproofing glue strip 7 in this fan body structure is met thermal expansion, and the slit between door and the frame will be filled, and when fire generation door leaf produces flexural deformation, still play the fire proof seal effect.Cut off into two spaces by PLASTIC LAMINATED 8 in the door body, when the surface temperature that warms oneself in front of a fire raises, because the partition effect of PLASTIC LAMINATED 8 is arranged, carry on the back the tangible temperature difference of aluminium silicate wool 10 generations of aluminium silicate wool 10 with the side towards the fire of fiery face, therefore carry on the back aluminium silicate wool in the fiery face chamber temperature that do not reach capacity, fibr tissue does not produce damage, has therefore reached the effect of fire-proof and thermal-insulation.
