Description

Reinforce structure for attaching inflammable materials}

The present invention relates to a reinforcing structure for attaching a flammable material to a fire door and a firewall, and more specifically, a plurality of first and second grooved steels are respectively fixed to the inner and outer plates of the fire door and the firewall. By forming a non-combustible material having a low thermal conductivity between the first and second grooved steel of the present invention relates to a reinforcing structure that can prevent the spread of embers through the grooved steel in the event of a fire to prevent the spread of fire.

In the conventional fire door and the firewall 10, as shown in FIG. 1, the inner plate 11 and the outer plate 11a are bonded to each other by welding by overlapping the inner and outer plates 11 and 11a with an appropriate width, and the inner and outer plates ( 11, 11a) between the insulation flame retardant 13 to block heat in the case of fire and the grooved steel 12, which is a reinforcing member of various forms to prevent the deformation of the fire door and the firewall 10 and to maintain the strength In order to pursue the splendor of the interior and exterior plates 11 and 11a, combustible materials 14 such as plywood are attached.

The reinforcing member is constructed with a reinforcing rod structure in which a panel or a steel strip having an appropriate thickness width is arranged according to the thickness of the fire door in an arbitrary form such as dividing the total area of the fire door and the firewall into a certain form. After arranging the reinforcing bars on the inner surface of the outer plate at appropriate intervals, attach the flanges formed at the side ends of each of the reinforcing bars first by means of the outer plate and the spot welding over several places, and then the inner plate and the outer plate overlapping the edges. Through the spot welding or general welding over the part to form a fire door and a firewall.

However, as an example, when a fire occurs inside a building, high temperature heat is applied to the interior plate. At this time, heat is blocked by the thermal insulation flame retardant, but heat is applied to the reinforcing member of the metal, and the high temperature heat is transferred to the exterior plate. This results in a flame on the combustible material.

Therefore, there is a problem that the fire spreads to the outside of the building, which causes more lives and property damage.

Therefore, in order to solve the above problems, the present invention prevents the fire from proceeding to the other side when a fire occurs, thereby preventing the occurrence of a larger fire in advance and also attaching a flammable material to the fire door and the firewall which can improve heat resistance. The purpose is to provide a reinforcing structure for the purpose.

In order to achieve the above object, the present invention is provided with grooved steel in order to prevent deformation of the fire door and maintain strength between the inner and outer plates of the fire door, but the first groove steel and the second inside of the inner plate and the outer plate, respectively. It is achieved by providing a reinforcing structure in which a grooved steel is attached and a nonflammable material which blocks heat between each grooved steel is sandwiched and fixed by fixing bolts.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2 is an exploded perspective view showing a fire door and a firewall according to the present invention;

Figure 3 shows an example of the combined cross section according to the present invention.

According to the present invention, a groove-shaped steel 12, which is a reinforcing member, is welded and fixed between a metal interior plate 11 and an exterior plate 11a, and a non-combustible fiber, glass wool, rock wool, etc. are formed in the interior and exterior plates 11 and 11a. In the conventional fire doors and firewalls (10) is filled with a heat insulating material 13 and the combustible material 14, such as MDF, plywood is attached to the outside of the interior / exterior plates (11, 11a),

A plurality of first grooved steels 12a are welded and fixed at regular intervals inside the interior plate 11, and a second gap is maintained within the exterior plate 11a to maintain the same spacing as the first grooved steel 12a. The groove 12b is fixed but the first groove 12a and the second groove 12b are formed to be spaced apart from each other.

The non-combustible material 15 having low thermal conductivity of the non-combustible and heat insulating material is inserted into the spaced portion between the first grooved steel 12a and the second grooved steel 12b.

In addition, fastening grooves 16 are formed in the first and second grooved steels 12a and 12b and the nonflammable material 15, respectively.

In the state in which the non-combustible material 15 is fitted in the first and second grooved steels 12a and 12b, the fixing bolt 17 is fastened so that the non-combustible material 15 is not detached from each of the fastening grooves 16. will be.

In the present invention having the structure as described above, if a fire occurs on one side of the interior plate 11 and the exterior plate 11a, heat, fire, and heat insulation are primarily performed from the interior and exterior plates 11 and 11a of the metal material. In addition, heat is blocked by the heat insulating material 13 filled between the inner and outer plates 11 and 11a.

Therefore, it is possible to prevent the fire from proceeding to the other side. For example, when a fire occurs in the interior plate 11 of the fire door and the firewall 10, heat of approximately 1000 ° C. is applied to the interior plate 11 of the metal material. As heat is transferred, high temperature heat is transferred to the first grooved steel 12a fixed to the inner plate 11.

However, the high temperature heat applied to the first grooved steel 12a by the nonflammable material 15 formed between the first grooved steel 12a and the second grooved steel 12b is transmitted to the second grooved steel 12b. It will block it.

Thus, the heat transmitted to the exterior plate 11a is blocked, so that no flame is generated in the combustible material 14 attached to the exterior plate 11a, thereby preventing a larger fire.

In addition, even when a fire occurs in the exterior plate 11a, heat is blocked as described above.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by any person having ordinary skill in the art without departing from the gist of the present invention claimed in the claims. Of course, such changes will fall within the scope of the claims.

Therefore, in the present invention, the grooved steel, which is a reinforcing member, is fixed between the inner and outer plates of the fire door and the firewall, but the first and second grooved steels are fixed to the inner and outer plates, respectively. The non-combustible materials with low thermal conductivity of non-combustible and insulated materials can be inserted and fastened to free the choice of materials for the interior and exterior panels, and to facilitate the addition of various decorative elements. It prevents the fire from spreading by the flammable material formed for the splendor of the outside, thereby minimizing the damage to life and property.
