Description

 {Framework of fireproof door}

The present invention relates to a door frame, and more particularly, to a door frame for a fire door which is improved in assembling structure to improve the efficiency of assembling work and is excellent in rigidity, excellent in heat insulation, soundproofing and dew condensation prevention, It is about.

In recent years, fire doors that can prevent the movement and spread of high temperature flames and toxic gases are frequently used in the event of a fire, and door frames for fire doors, which are made of iron, are also often used. The door frame for the fire door is generally manufactured by a method in which an iron metal plate is integrally formed by bending, and is composed of a horizontal member formed on the upper side and a lower side, and a vertical member formed on the left side and the right side.

The assembly of the door frame and door frame for a conventional fire door will be described with reference to FIG.

As shown in Fig. 8A, the door frame for a conventional fire door is welded to three sides of the vertical member 10A after the horizontal member 10 is brought into contact with the side face of the vertical member 10A. When the door frame for a fire door is assembled with a wall, a heat insulating material 40 for improving heat insulation, sound insulation and dew condensation preventing property is connected to the wall or the chassis as shown in FIGS. 8A and 8B.

The horizontal member 10 and the vertical member 10A of the door frame for the conventional fire door have a body 11 by bending a plate-shaped iron plate, a side wall 12 bent upward from both sides of the body, And a heat insulating space 13 to which a heat insulating material 40 is connected between the side wall 11 and the side wall 12.

The body 11 includes a bottom door 11a at the bottom, a vertical bend 11b formed at one end of the door handle 11a and a vertical bend 11b formed at the top of the vertical bend, And a fire door receiving portion 11c.

The door frame for a conventional fire door can be assembled only by a skilled welder due to a welding method, and the assembling efficiency is greatly reduced due to post-processing such as grinding after welding, and the cost of the product is increased. Also, it is not easy to fix the horizontal member and the vertical member at right angles before welding the door frame for the fire door, so that the assembly quality defect is frequent.

8A and 8B, since the horizontal member 10 and the heat insulating space 13 of the vertical member 10A are not connected to each other, the horizontal portion and the vertical portion of the heat insulating material 40 are disconnected, There is a problem that the heat insulating property, the soundproofing property and the dew condensation preventing property are deteriorated.
