Abstract

A panel for the fire prevention door is provided that the partial alternation and repair are possible in case that door is damaged. A panel for the fire prevention door comprises plate members(2a,2b) forming the recess portion processed to a plurality of blanking works in the surface, a finishing panel(1) attached and set on the rear side of the plate member, an ornament panel attached and set on the outside direction side of finishing panel, a connection bolt(3) fixed to screw-nut through the recess portion, a fixing member(4) including the recess between the fixing plate, and is fixed to the spot welding, two or more cell unit panels including an H-beam(5) inserted and set up in the recess.

Description

Panel for fire prevention door {Panel for fire prevention door}

The present invention relates to a structure of a fire door, and more particularly, to a panel for an oriental fire door to facilitate the disassembly and assembly, and to improve durability to prevent deformation and breakage caused by bearing force and impact.

Conventionally, fire doors, such as the front door of an apartment constructed for the purpose of fire protection, are manufactured by manually bending a plurality of reinforcement plates and welding them manually. Such welded parts are often twisted and rusted. The present invention was able to prevent the door from melting or twisting due to high heat according to the invention of Korean Patent No. 321494. However, the door has a problem in that it is not economical in maintenance because it is impossible to replace and repair partially.

Another problem is that the fire door is made of a single color, so that it is monotonous by using it semi-permanently unless it is replaced or changed to a different color.

Therefore, the present applicant has proposed Korean Patent Registration No. 490827 in view of the above-mentioned conventional problems, and the above-described Korean Patent Registration No. 490827 of the applicant has maintained maintenance by enabling partial replacement and repair in case of damage to the door. In addition to being easy to use and partial replacement, it is possible to easily change and decorate the shape of the door without changing the whole color or painting to other colors so that it can always provide new aesthetics, but it is weak to external impact. I had a problem.

The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to maintain and facilitate maintenance by partially replacing and repairing the door in the event that the applicant has a registered Korean Patent Registration No. 490827. In addition to the possibility of partial replacement, the door can be easily changed and decorated to the desired shape without having to replace all the doors or change the color to another color, thereby providing new aesthetics and transforming against external shocks. It is to provide a panel for a fire door to further increase the bearing capacity to prevent the damage.

An object of the present invention described above is a plate body formed with a recessed portion processed in the c-shaped by a plurality of blanking operations on the surface; A closing panel attached to the rear surface of the plate; A decorative panel attached to an outer surface of the finishing panel; A connecting bolt fixed through the recess of the plate and fixed with a nut; A fixing member formed at both ends of the plate body at both ends and having grooves therebetween to fix the spot plate by spot welding; A fire door panel comprising two or more panels of a cell unit including an H beam inserted into the groove, comprising: a fixing bush through which a connection bolt passes between the plate and the plate; It is achieved by a panel for fire doors, characterized in that it comprises a support board that is sandwiched between the fixing bush is supported and installed between the fixing members installed opposite to both sides.

The present invention having the structure as described above allows a partial replacement and repair in case of damage to the door, thereby facilitating maintenance and allowing partial replacement, thereby pursuing the shape without purging or replacing all of the doors with other colors. It is easy to change and decorate so that it can always provide a new aesthetic, and also has the effect of increasing the supporting force to prevent deformation and breakage against external impact.

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

1 to 2 of the accompanying drawings are a perspective view and an exploded perspective view showing the structure of the present invention, the panel for the fire door of the present invention is a plate body (2a, 2b) formed with recesses (21, 22) and the finishing panel (1) And a fixing bolt (4, 4 ') fixed to the connecting bolt (3) through the decorative panel (10), the recesses (21, 22), the plate body (2a, 2b) by spot welding, and the fixing member The fixing bush 6, 6 'and the fixing bush are installed between the H beam (5, 5') and the plate (2a, 2b) inserted into the (4, 4 ') and the connecting bolt (3) through It is sandwiched between the support bushes (6, 6 ') and is supported, and is configured to include a support board (7) which is installed to be sandwiched between the holding members (4, 4') installed opposite to both sides.

More specifically, as shown in FIG. 3, the front and rear plates 2a and 2b having a flat surface with a predetermined size are blanked in an opposite state or a straight line to give a reinforcing function to a predetermined shape. The connecting bolts 3 penetrate the provided recesses 21 and 22 and are fixed with nuts.

On the other hand, the outer surface portion of the plate (2a, 2b) is attached to the finishing panel 1 and the decorative panel 10 is attached to the fixed plate (42, 42 'at both ends between the plate adjacent to the plate (2a, 2b) ), And fixing members 4 and 4 'having grooves 43 and 43' are installed therebetween, and when spot welding them, a panel for fire doors is fixed and the reference numeral 30 denotes an impact made of a foam material. Absorption means.

On the other hand, the fixing member (4, 4 ') grooves (43, 43') is inserted into the H beam (5, 5 ') to support the end of the panel located in the space when the panel is coupled, the H It is preferable to install the beams 5, 5 'to protrude outward from the decorative panel 10, for the purpose of facilitating disassembly and assembly.

In the fireproof door panel of the present invention, two or more panels of the cell unit are combined to form a fireproof door. As illustrated in FIG. 4, a fireproof door, that is, a decorative panel 10 is painted with different colors. If you want to configure the color of the picture differently, remove only the part and replace the cell unit panel with different color to have a new aesthetic.

At this time, the fixing members 4, 4 'and the H beams 5, 5' connect the plates 2a, 2b and the adjacent plates 2a, 2b to improve the rigidity of the connecting portion, and Even when the panel is damaged due to the impact, it is a part to remove and repair only the damaged cell panel.

Meanwhile, the fixing bushes 6 and 6 'installed between the plate bodies 2a and 2b and penetrating the connecting bolts 3 serve as fixing means for holding the supporting board 7 while maintaining a gap therebetween. In addition, the support board 7 is installed so as to be sandwiched between the fixing members (4, 4 ') installed to be opposite to both sides to prevent deformation and damage to the external impact.

1 is a perspective view of a panel to which the technique of the present invention is applied.
