Abstract

The utility model relates to a wooden fire door, which is composed of a door frame and a door leaf which are connected through a hinge. The utility model is characterized in that a foaming insulating panel for flame resistance and heat insulation is installed on counterfire surfaces of the wooden door frame and the wooden door leaf, and a foaming seal gasket for flame resistance and heat insulation is installed on the door frame. The wooden door frame and the wooden door leaf are soaked through fire retardant. The thickness of the foaming insulating panel of counterfire surfaces and the foaming seal gasket is 11 times greater than the original thickness thereof rapidly after the fire occurs, and thus, the wooden fire door can realize fire prevention by sealed effectively to prevent flame penetrating.

Description

Wooden fire door

The utility model relates to a kind of fire-proof wooden door, and it is formed by connecting through hinge by doorframe, door leaf.

The door leaf of at present commercially available fire-proof wooden door is made up of timber and asbestos structure.This door exists the defective that thick, the anti-firepower difference of door leaf and asbestos are detrimental to health.

The purpose of this utility model just provide a kind of door leaf structure with common wooden door leaf thickness identical and fire resistance property by force, the fire-proof wooden door that is not detrimental to health.

The purpose of this utility model is finished like this: a kind of fire-proof wooden door, be formed by connecting through hinge by wooden doorframe, wooden door leaf, fire-retardant, heat insulation foaming heat insulation plate is housed on the counter-fire face of wooden doorframe, wooden door leaf, fire-retardant, heat insulation foaming sealing mat is housed on doorframe.

The purpose of this utility model can be finished equally like this: the sealing decorative panel through the fire retardant immersion treatment is housed in the outside of foaming heat insulation plate.

The utlity model has following advantage:

1, reasonable in design, the thickness of door leaf is identical with common wooden thickness gate, thereby in light weight, easy to use.

2, cancelled asbestos structure, eliminated the harm of asbestos health.

3, this fire-proof wooden door is not only rational in infrastructure, and the fire-proof and thermal-insulation effect is higher than traditional fire-proof wooden door 2---and 3 times.Its fire resistance period can reach 90 minutes.

Fig. 1 is a kind of structure chart of fire-proof wooden door;

Fig. 2, Fig. 3 are a kind of A-A sectional views of fire-proof wooden door;

Further be illustrated below in conjunction with drawings and Examples, but be not limited only to following examples.

By accompanying drawing 1,2,3 as can be known, a kind of fire-proof wooden door is formed by connecting through hinge (4) by wooden doorframe (2), wooden door leaf (3).Fire-retardant, heat insulation foaming heat insulation plate (7) is housed on the counter-fire face of wooden door leaf (3), fire-retardant, heat insulation foaming sealing mat (1) is housed on doorframe (2).Sealing decorative panel (6) through the fire retardant immersion treatment is housed in the outside of foaming heat insulation plate (7).Foaming heat insulation plate (7) and foaming sealing mat (1) after fire takes place, increase sharply into original thickness 10 times of thickness.Thereby seal fire-retardantly, heat insulation effectively, realize fire prevention.

By accompanying drawing 1 door lock (5) as can be known also.

The wooden part of fire-proof wooden door of the present utility model is all soaked through fire retardant.Door leaf (3) is whole wooden structures.Foaming heat insulation plate (7) thickness is between 2-4mm.

Claims

1, a kind of fire-proof wooden door, be formed by connecting through hinge (4) by wooden doorframe (2), wooden door leaf (3), it is characterized in that: fire-retardant, heat insulation foaming heat insulation plate (7) is housed on the counter-fire face of wooden doorframe (2), wooden door leaf (3), fire-retardant, heat insulation foaming sealing mat (1) is housed on doorframe (2).

2, a kind of fire-proof wooden door according to claim 1 is characterized in that: the sealing decorative panel (6) through the fire retardant immersion treatment is housed in the outside of foaming heat insulation plate (7).
