The present invention relates to an emergency exit door bracket for fire shutters, and more particularly, the installation work of the bracket to be installed on the emergency exit door can be made more easily and quickly while preventing smoke from escaping into the gap of the emergency exit door when a fire occurs. The emergency exit door bracket for a fire door.

In general, a fire shutter is installed inside a building, and normally serves as a shutter to prevent outsiders from entering a specific space. In the event of a fire, flame, smoke, and toxic gas are spread. To prevent it. Therefore, it is mandatory to install the building more than a certain size (department store, shopping mall, conference chair, etc.) by fire method.

In particular, as shown in the Daegu subway fire disaster or fire events of various buildings, if a fire occurs inside the building, those who cannot exit the building are exposed to toxic gases and flames. Therefore, fire shutter must meet various requirements such as fire resistance, burst resistance, and flame retardancy through fire test and burst test assuming fire situation. It is a very important criterion for evaluating safety and safety and minimizing human and material damage.

Therefore, the fire shutter must satisfy the requirements of heat resistance, burst resistance, flame retardancy, etc. in the case of components such as hinges, emergency escape door brackets, and end brackets, as well as slats constituting the fire shutter simply.

In particular, the emergency exit door bracket is installed to block the gap between the fire door (S) and the emergency exit door (D), as shown in Figure 1, the end of the slat (D1) of the emergency exit door (D) It also strengthened and prevented smoke from leaking in case of fire.

FIG. 2 is an enlarged view of a portion A of FIG. 1 showing the structure of the conventional emergency escape door bracket for fire prevention shutters, and as shown, the conventional emergency escape door bracket 40 is a slat (S1) of the fire prevention shutter (S). The first and second brackets 50 and 60 are fixed to the end and the slat end of the emergency exit door D by spot welding, respectively, to shield the gap between the fire prevention shutter S and the emergency exit door D. Done.

However, since the emergency exit door bracket 40 installed in the conventional fire shutter (S) has a structure in which a synthetic resin material is molded on a slat of a thin steel plate, the synthetic resin material is easily burned or thermally deformed by a high temperature when a fire occurs, and the first and second brackets ( 50) (60) also had a problem of thermal deformation. Therefore, a fatal defect occurred such that the heat resistance and the smoke resistance of the fire shutter (S) were remarkably inferior, and the normal opening and closing of the emergency escape door (D) was also difficult.

In addition, since the conventional emergency exit door bracket 40 is installed in the slats D1 of the emergency exit door D, respectively, the emergency exit door bracket 40 cannot be installed in a confidential manner, so the emergency exit door bracket 40 is Even after the installation, the emergency exit door (D) has a problem that the overall sag.

That is, the plurality of slats D1 are coupled to each other through the bending portion D2, and the bending portions D2 set a relatively large tolerance for smooth coupling, and the tolerances are coupled to the plurality of slats D1. Thereafter, the emergency exit door (D) caused a phenomenon that sag due to its own weight.

Therefore, if the plurality of emergency exit door brackets 40 are more confidentially coupled, it is possible to prevent sagging due to the weight of the emergency exit door D, but the conventional emergency exit door brackets 40 are not mutually confidential. Therefore, the coupling tolerance between the slats (D1) could not be corrected, which causes the emergency exit door (D) to sag due to its own weight, and an additional deflection prevention member is further added to the lower end of the emergency exit door (D). There was a problem that must be installed.

Furthermore, in the prior art, a plurality of emergency exit door brackets 40 are installed on the fire shutter (S) and the emergency exit door (D), so that the means for easy coupling between the emergency exit door brackets 40 are not provided. Inconvenient problem of fixed installation by spot welding, etc. while adjusting the position of the emergency exit door bracket 40 of each, this caused a problem that the workability of the emergency exit door bracket 40 is lowered and the installation time is delayed It became.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is an emergency for fire shutter that can prevent the combustion of the bracket installed near the emergency escape door in the event of fire To provide an escape door bracket.

In addition, an object of the present invention is to provide an emergency exit door bracket for fire prevention shutters to improve the flame retardancy and prevent the emergency exit door sagging by its own weight to ensure that the bracket installed near the emergency exit door to be airtightly assembled. .

And another object of the present invention is to provide an emergency exit door bracket for fire prevention shutter that can be easily and quickly installation of the bracket is installed near the emergency exit door.

Emergency escape door bracket for fire prevention shutters of the present invention for achieving the above object is the first bracket and the second bracket having an end bar and a blocking plate and a fixing plate between the slat of the fire shutter and the emergency escape door through the fixing plate installation means. In the emergency exit door bracket for the fire shutter is provided, the end bar is formed in the upper and lower ends of the engaging piece having the upper and lower ends of the end bar arc-shaped, and on either side of the inner side or the outer side of the engaging piece of the other first bracket It characterized in that the reinforcing coupling means is formed to form the same coupling groove as the arc shape of the coupling piece so that the coupling piece and the rotation freely and hermetically.
