Description

Fire door reinforced intensity "

More particularly, the present invention relates to a fire door improved in strength, which can reinforce strength without providing an inner frame between the plates, simplifies the manufacturing process, reduces material costs, To a fire door reinforced with a strength to which a hinge which does not deteriorate durability under the influence of high temperature is reinforced.

Generally, a fire door is applied to an entrance of an apartment or a building, and a fire door is provided along an inner wall of an entrance formed at a wall. The fire door is hinged to the fire door so that the fire door is rotated in one direction.

An example of such a fire door is found in Korean Patent No. 10-1168806, "Reinforcement Fire Door. &Quot;

1 is a view showing an example of a conventional fire door.

1, a conventional fire door is provided with a reinforcing inner frame 2 on the inner periphery of a fire door composed of two metal plates 1a and 1b. The fire door has a wing 1c on one side thereof The reinforcing portion 2b of the side bar 2a constituting the inner frame 2 is inserted into the wing 1c of the fire door so as not to be deformed.

In addition, the conventional fire door is filled with a material such as fire-proof material or honeycomb which is filled in the spaces between the plates 1a and 1b, and a separate hinge is provided to fix the fire door to the fire door.

However, in the conventional fire door, the inner frame 2 is provided between the plate bodies 1a and 1b, which increases the manufacturing process and increases the cost of raw materials.

2 is a view showing an example of a hinge member installed in a conventional fire door.

2, the hinge member 3 according to the related art includes a rotation hinge 4 provided on a fire door (not shown), a rotary shaft 5a mounted on the fire door, The rotary hinge portion 4 includes a fastening portion 4c fastened with a bolt and a support plate 4a formed with an insertion groove 4b assembled to the rotary shaft 5a. Lt; / RTI >

The fixed hinge portion 5 includes a base plate 5b on which a rotary shaft 5a is installed and a vertical plate 5c vertically formed on one side of the base plate 5b to form a fire door frame Respectively.

When the hinge member 3 is subjected to a long period of time due to the self weight of the fire door or when it is influenced by a high temperature caused by fire, the bending of the fixed hinge part 5 is relaxed, and the fire door is not easily opened by being caught in the fire door, There is a problem of causing economic loss.

In addition, the conventional hinge member 3 has poor durability when the hinge member 3 is mounted on the fire door, so that the hinge member 3 does not function properly.

Registration No. 10-1168806 {Registered on July 19, 2012}

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the prior art described above, and it is an object of the present invention to provide a method of reinforcing strength without providing an inner frame between plates, simplifying a manufacturing process, reducing material costs, And a hinge which is not deteriorated in durability even under the influence of a high temperature caused by a fire.

The present invention provides a fire door having a reinforced strength, comprising: a front plate body having a first reinforcing portion formed by bending the upper and lower surfaces thereof, a first reinforcing piece formed by bending one side of the first reinforcing portion horizontally, And a second reinforcing piece is formed by horizontally bending one side of the second reinforcing part so that the first reinforcing piece and the second reinforcing piece are overlapped to each other to form a second reinforcing piece, And a hinge coupled to a hinge slot formed on one side of the lower surface of the lower plate coupled to the back plate. The hinge is bent in a vertical plane with a horizontal plane, a hinge shaft hole is formed in the horizontal plane, And is screwed into the hinge slot.

In order to accomplish the object of the present invention, the reinforced-fire door according to the present invention is characterized in that the first reinforcing piece of the front plate body and the second reinforcing piece of the rear plate body are overlapped with each other so that the front plate body and the rear plate body are joined, , The hinge is formed by joining the hinge to the hinge slot formed at one side of the lower surface, the strength can be reinforced without providing the inner frame between the plates, the manufacturing process is simple, the material cost is reduced, Which is reinforced by a hinge which is not deteriorated in durability even if it is influenced by a fire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 3 is an exploded perspective view of a fire door according to the present invention, FIG. 4 is a front sectional view of a fire door according to the present invention, and FIG. 5 is a side sectional view of a fire door according to the present invention.

2 to 5, the reinforced reinforced door 100 according to the present invention includes a front plate 10, a rear plate 20 and a hinge 30. [

The front plate member 10 has a first reinforcing portion 11 formed by bending the upper and lower surfaces thereof and a first reinforcing member 12 formed by bending one side of the first reinforcing portion 11 horizontally.

In addition, one side of the side surface is bent to form the first side surface plate portion 13.

The upper and lower surfaces of the rear plate member 20 are bent to form a second reinforcing portion 21 and one side of the second reinforcing portion 21 is bent horizontally to form a second reinforcing piece 22, The reinforcing member 12 and the second reinforcing member 22 are overlapped to each other.

In addition, one side of the side surface is bent to form the second side surface plate 23. [

The hinge 30 is coupled to a hinge slot 40 formed on one side of the upper and lower surfaces of the front plate body 10 and the rear plate body 20.

The hinge 30 is folded into a horizontal plane 31 and a vertical plane 32. A hinge shaft hole 31a is formed in the horizontal plane 31 and a coupling hole 32a is formed in the vertical plane 32 So as to be screwed into the hinge slot 40.

The front plate body 10 and the rear plate body 20 are bent so that the upper and lower surfaces of the front plate body 10 are bent and the first reinforcing portion 11 The first reinforcement member 11 is bent horizontally to form the first reinforcement member 12 and the first side plate member 13 is formed by bending one side of the side surface.
