Description

Steel-wood fireproof door structure

Technical Field

The utility model relates to a prevent fire door technical field, specifically be a fire door structure is prevented to steel wood matter.

Background

Referring to fig. 1 to 5, the steel-wood fire door with the traditional structure is formed by using a steel material as a door frame (001), using flame-retardant plywood (002) and a fire-retardant plate (003) as a panel (004), filling a fire-retardant door core plate (005) in the middle of the panel (004), and using flame-retardant wood as a framework (006) for reinforcement.

However, the flame-retardant wood is wood soaked in the flame-retardant liquid, so that a large amount of wood is inevitably used, and resources are wasted. The flame-retardant liquid used in the method is also easy to pollute the environment. And the wooden framework is easy to age after being used for a long time, so that the strength of the door leaf is reduced, and the fireproof gate pole is easy to damage. In addition, at present, many enterprises do not need to soak the wood with the flame retardant solution for convenience, namely, the wood without flame retardant treatment is directly used as a framework, so that the fire is not prevented, and the risk of fire is increased.

The fireproof door is characterized in that a fireproof door core plate is arranged in the middle of the door leaf, a fireproof door middle plate is fixed on the outer layer of the fireproof door core plate, a framework is fixed at the end connection part of the fireproof door middle plate and the fireproof door core plate, and a fireproof door outer plate is fixed on the outer side of the fireproof door middle plate.

Preferably, the cover seam plate and the framework are made of cold-rolled galvanized steel plates.

Preferably, the fireproof door core plate is a magnesium oxide core plate.

Preferably, the middle plate of the fireproof door is a glass magnesium fireproof plate.

Preferably, the outer plate of the fireproof door is made of a flame-retardant medium-density fiberboard.

Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model discloses, the fire door structure is prevented to peculiar steel wood is that the wooden skeleton in the traditional structure is fallen with the skeleton replacement of steel material preparation, resources are saved, environmental protection does not have the conflagration dangerous to the steel skeleton is more durable, and is higher than the intensity of wooden skeleton, makes the life who prevents fire door improve greatly.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 6 to 11, the present invention provides a technical solution: a steel-wood fireproof door structure comprises a door frame 1 and a door leaf 2, wherein 1.2mm cold-rolled galvanized steel plates are preferably selected on the door frame 1, 61mm thickness of the door leaf 2 is preferably selected, a fireproof door closer 3 is installed between the top of the door frame 1 and the top of the door leaf 2, the type GA93-3CIII (B3W) is preferably selected on the fireproof door closer 3, a fireproof hinge 4 is installed between one side of the door frame 1 and one side of the door leaf 2, 4.5 inches of the fireproof hinge 4 is preferably selected, a fireproof lock 5 is installed between the other side of the door frame 1 and the other side of the door leaf 2, the type GXF-101(A) -A6 is preferably selected on the fireproof lock 5, a seam covering plate 6 is installed at the closing position of the door frame 1 and the door leaf 2, the seam covering plate 6 is preferably 0.8mm cold-rolled galvanized steel plates, the structure has elasticity, so that the left side of the fireproof door leaf abuts against the door leaf 2, the door leaf 2 is more, the fire-resistant intumescent seal 7 is preferably of the type FPJ-B-25 x 2 and is used to close off the gap and prevent the passage of fire.
