Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 9, an embodiment of the present invention provides a fire door with high isolation, including: frame 1 and door plant 11, frame 1 and door plant 11 rotate to be connected, and frame 1 adopts the steel frame, and the gap distance between frame 1 and the door plant 11 sets up according to relevant national standard.

The frame 1 inboard sets up to the notch cuttype structure, and the door plant 11 of being convenient for pastes and leans on, simultaneously, closes the door back, leaves dogleg shape gap around door plant 11 and the frame 1, and the air current can not be fast directly through this gap, but has a process of turning the quarter bend, can slow down air speed.

The four sides of the door panel 11 are respectively provided with an L-shaped fire-proof strip 12, and the L-shaped fire-proof strips 12 can be attached to the inner side of the outer frame 1. In order to improve the leakproofness, set up L shape fire prevention strip 12 around door plant 11, one side of the L shape structure of L shape fire prevention strip 12 can fill half of the inboard notch cuttype structure of frame 1 just, and another half plays the effect of blockking in the outer gap department of frame 1 and door plant 11, and the leakproofness of preventing the fire door is promoted through the mode that L shape fire prevention strip 12 blocks the gap while filling the gap. In addition, the L-shaped fire-proof strip 12 can be made of fluororubber or silicon rubber, has certain elasticity and good high-temperature resistance, can well fill a gap between the outer frame 1 and the door panel 11, can expand slightly when heated, further fills the gap between the outer frame 1 and the door panel 11, avoids dense smoke from passing through, and has good isolation. In addition, in order to promote the degree of agreeing with of L shape fire prevention strip 12 and frame 1 inboard, set up the inboard of L shape fire prevention strip 12 into the arc structure, set up to the fillet structure with the frame inboard of the 12 laminating of L shape fire prevention strip, the laminating that above-mentioned arc structure and fillet structure can be fine, and the leakproofness is better.

An arc-shaped protrusion 13 is arranged on the inner side of the L-shaped fireproof strip 12 on one side far away from the rotary connection part of the door panel 11 and the outer frame 1, an arc-shaped groove 14 is arranged on the inner side of the outer frame corresponding to the side, and the shape of the arc-shaped protrusion 13 is matched with that of the arc-shaped groove 14. Set up protruding 13 of shape assorted arc and arc recess 14 and make door plant 11 paste with frame 1 and lean on promptly the back that the fire door closed, protruding 13 card of arc is gone into in the arc recess 14, make prevent that fire door is difficult for being blown open by the wind, in addition, because keep away from one side of preventing fire door rotation center and the gap between frame 1 need set up according to relevant standard than other trilateral gaps a little wide, consequently, set up this gap of filling that protruding 13 of arc and arc recess 14 can be fine, and because L shape fire prevention strip 12 adopts fluororubber or silicon rubber to make, the cooperation joint of protruding 13 of arc and arc recess 14 can not influence opening and closing of preventing fire door under the prerequisite that promotes to prevent fire door leakproofness.

Because the rotating connection part of the fireproof door is provided with the rotating shaft, the sealing performance is poor, therefore, the rotating connection part of the outer frame and the door panel is covered with the fireproof rubber sheet 15 to cover the rotating shaft to make up the defect of poor sealing performance, and the fireproof rubber sheet 15 is made of fluororubber or silicon rubber and has good high-temperature resistance.

The door panel 11 comprises a wooden frame 2, an inner fireproof plate 3 and an outer fireproof plate 4, wherein the wooden frame 2 is formed by connecting a plurality of short square timbers, and the wooden frame 2 has good heat insulation performance.

Ripple agrees with groove 5 has been seted up at the both ends of short square timber, agrees with 5 cooperation fixed connection through ripple between the many short square timber, for further promoting the joint strength between the many short square timber, can agree with 5 interior fire-proof glue of coating in the groove in ripple, agrees with 5 cooperation bonds through ripple between the many short square timber.

Be provided with many wood system in the wood system frame 2 and prop 6, set up wood system and prop 6 intensity that can improve wood system frame 2, make 2 non-deformable of wood system frame, wood system props 6 and can prop 6 mutual parallel arrangement through

many vapour nails

10 and 2 fixed connection of wood system frame and many wood systems.

The fireproof material 7 is filled between the wooden frame 2 and the wooden support 6, the fireproof material 7 is a fireproof filling material, the material can be a perlite fireproof door core board, the main components of the material comprise magnesium oxide, magnesium chloride, sawdust and perlite, and the material has the characteristics of no toxicity, no odor, environmental protection, fire prevention, moisture prevention, corrosion resistance, convenience in construction, light weight, high strength, heat insulation, heat preservation, cutting, planing and sawing.

The inlayer PLASTIC LAMINATED 3 bonds with wood system frame 2 through fire-proof glue 8, and outer PLASTIC LAMINATED 4 bonds with inlayer PLASTIC LAMINATED 3 through fire-proof glue 8, sets up thermal-insulated and fire behavior that double-deck PLASTIC LAMINATED can effectively promote fire door. The inner layer fire-proof plate 3 and the outer layer fire-proof plate 4 can adopt magnesium sulfate-glass magnesium plates, the main components comprise active high-purity magnesium oxide, magnesium sulfate, alkali-resistant glass fiber cloth, flexible plant fiber, non-combustible light perlite, chemically stable lithopone and the like, the fireproof paint has the characteristics of high temperature resistance, flame retardance, sound absorption, shock resistance, insect prevention, water and moisture resistance, light weight and corrosion resistance, and the surface can be directly sprayed with fireproof paint.

2 lateral surfaces of wood frame have fire prevention lath 9 through 8 pastes of fire-proof glue, and outer PLASTIC LAMINATED 4 and the 9 surface coating of fire prevention lath have fire prevention lacquer, and fire prevention lath 9 can adopt the material the same with inlayer PLASTIC LAMINATED 3 and outer PLASTIC LAMINATED 4 for the side of protection wood frame 2 places 2 high temperature combustion of wood frame. The fire-proof paint can adopt organic silicon high-temperature resistant paint, the main components comprise organic silicon resin, special high-temperature resistant pigment and organic solvent, and the paint has the characteristics of quick self-drying, strong adhesive force, excellent heat resistance and weather resistance of a coating film, and capability of enduring the high temperature of 200-800 ℃ for a long time.

To sum up, the embodiment of the utility model provides a fire prevention door with high isolation sets up L shape fire prevention strip around the door plant, and the shape of L shape fire prevention strip and the inboard shape phase-match of frame close the door back, and it is higher with the frame laminating degree around the door plant, and one side of L shape fire prevention strip can fill the gap between door plant and the frame, and the another side can play the effect that blocks, promotes the leakproofness, compares in current fire prevention door, the utility model discloses the effect of the dense cigarette of better separation has.
