Description

Fire closure shutter {Fire closure shutter}

The present invention relates to a fire prevention shutter that prevents the spread of flame, smoke, etc. in the event of a fire, and more particularly, the installation of the fire prevention shutter can be made more easily and quickly while preventing smoke from escaping into the gap of the fire prevention shutter. It is about fire prevention shutter which there is.

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 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 a plurality of slats constituting the fire shutter simply.

Figure 1 shows the installation state of the hinge, emergency escape door bracket, and end bracket of the discharge shutter, such that the hinge 10 is installed to open and close the emergency exit door (D) in the fire shutter (S) and the hinge function and It performs a smoke-retardant function, the emergency exit door bracket 40 is installed to block the gap between the fire door (S) and the emergency exit door (D) to reinforce and end the end of the emergency exit door (S) slat (D1) And the end bracket 70 is installed on both ends of the slat (S1) of the fire shutter (S) to perform the reinforcement and shielding function of the slat (S1).

FIG. 2 is an enlarged view of a portion A of FIG. 1 showing the hinge of the fire shutter shutter in detail, and the conventional hinge 10 is usually the first and second hinge brackets 20 (not shown) by pins and springs (not shown). 30) consists of a hinged structure.

First, the first hinge bracket 20 of the hinge 10 is a fixing plate 21 fixed to the spot (Spot) to the slat S1 of the fire shutter (S) and the upper vehicle on which the bending piece 23 is formed The soft plate 22 and the lower shield plate 24 are integrally formed. In addition, the second hinge bracket 30 is integrally formed with a fixed plate 31, a side difference piece 32, and a lower difference piece 33 fixedly installed by spot welding.

However, since the hinge 10 installed in the conventional fire shutter (S) is easily deformed from the side hinge piece 32 of the second hinge bracket 30 in the cooling process due to the characteristics produced through the casting process, it is illustrated in FIG. 2B. As described above, there is a problem that the gap does not come into close contact with the bending part D2 of the emergency exit door D and the assembling work is difficult.

That is, since the side hinge piece 32 of the second hinge bracket 30 is a protruding thin plate shape, the side hinge piece 32 is easily deformed, such as being inclined to one side due to its own weight during the cooling process, and thus the side face plate 32 is deformed. In the case of assembling without correcting), as shown in FIGS. 2A and 2B, a problem that cannot be brought into close contact with the side of the bending part D2 of the emergency exit door D occurs, so that the flame retardant function and There was a problem of significantly lowering.

Therefore, in the related art, in order to correct the deformation of the side shielding plate 32, the side shielding plate 32, which is deformed through a hammer or the like, has been corrected by hand, but all the side shielding plates due to the characteristics of the second hinge bracket 30 produced by casting. (32) to be manually corrected by hand, which causes a problem that the productivity of the hinge 10 is greatly reduced.

In addition, in the prior art, since a plurality of hinges 10 are not provided with means for easy coupling between the hinges 10 in the installation process of the fire shutter (S), the operator spots the hinges 10 while adjusting their positions one by one. Inconvenient problem of fixed installation by welding, etc. has occurred, and this causes a problem that the workability of the fire shutter (S) falls and the installation time is delayed.

On the other hand, the emergency exit door bracket 40 shown in detail in Figure 1 is to shield the gap between the fire escape shutter (S) and the emergency exit door (D), the end of the slat (S1) of the fire shutter (S) And the first and second brackets 50 and 60 at the ends of the slats D1 of the emergency exit door D, respectively, are fixed by spot welding or the like.

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 thin steel plate, the synthetic resin material is easily burned or thermally deformed by a flame when a fire occurs, and the first and second brackets 50 are used. (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 coupling portions D2 set a relatively large coupling tolerance for smooth coupling, and the coupling tolerances include a plurality of slats D1. After being combined, the emergency exit door (D) caused a phenomenon of sagging by 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.

In addition, the end bracket for the fire prevention shutter 70 shown in detail in FIG. 1 is not installed at both ends of all the slats S1 of the fire protection shutter S, but is fixedly installed by welding or the like one by one to provide a plurality of slats S1. ) Is prevented from sliding left and right.

However, such a conventional firebutter shutter end bracket 70 can not be expected from the structural difference that is installed on the slats (S1) one by one, and can be firmly reinforces both ends of the slats (S1) of the fire prevention shutter (S). There was no problem.

On the other hand, Figure 3a is a front view showing another conventional fire shutter is installed on the left end of the fire escape door, the emergency fire shutter (S) is the hinge 10, the end bracket 70, similar to the conventional configuration described above ) Is the same in that it is installed in the fire shutter (S), but there is a difference in that the end bracket 71 is installed at the end of the emergency exit door (D).

Therefore, the conventional fire protection shutter end bracket 71 can be expected to reduce the noise slightly when closing the emergency exit door (D) as shown in Figure 3c, as shown in Figure 3c end bracket ( Since 71) does not cover the bending portion D2 of the slat D1, a problem in which a smoke retardation effect is remarkably degraded in case of fire occurs.

In addition, the end bracket 71 of the conventional fire shutter (S) is easily burned and deformed by the flame and loses the smoke-retardant function, and the opening and closing of the emergency exit door (D) and the fire prevention shutter due to the deformation of the end bracket (71). There was also a problem that the operation of S) can not be performed normally.

Moreover, conventionally, when the end brackets 71 were respectively installed on the slats D1 of the emergency exit door D, the end brackets 71 were not airtightly installed. Therefore, even after the end bracket 71 is installed as in the emergency exit door bracket 40, the emergency exit door D sags as a whole.

In addition, when the fire is a conventional fire shutter (S) is heated to a high temperature by the flame is not only the fire shutter (S) but also the heat escape emergency door (D) of the fire prevention shutter (S) is deformed, this process In addition, parts such as springs (not shown) inside the hinge 10 installed in the emergency exit door (D) are melted or severely deformed and broken, so that the emergency exit door (D) opens spontaneously.

Therefore, the conventional fire shutter (S) is very vulnerable to the flame in the event of a fire caused a serious defect that can not properly prevent the spread of smoke and flame.

As described above, in the conventional fire shutter (S), since the hinge 10, the emergency escape door bracket 40, and the end brackets 70 and 71 are installed, a lot of gaps are generated and the flame retardancy is significantly reduced. , The installation of each part could not be made easily and easily, there was a problem that the deflection of the emergency exit door (D) occurs.

In addition, the conventional fire shutter (S) is not the normal operation of the fire prevention shutter (S) such as the deformation or combustion of the above parts due to the fire in the fire, and thus the flame and the basic role of the fire shutter (S) There was a serious problem that could not properly prevent the spread of smoke.

The present invention has been made to solve the conventional problems as described above, the object of the present invention is to install the airtight hinge, emergency escape door bracket, end bracket of the airtight seal to greatly improve the flame retardancy of the fire shutter In addition, the present invention provides a fire prevention shutter that can prevent sagging of emergency exit doors.

Another object of the present invention is to provide a fire door shutter that can be easily and quickly installation work of the fire door shutter because the hinge of the fire door, emergency escape door bracket, end bracket is easily installed.

Still another object of the present invention is to provide a rigid fire shutter that can operate normally without being deformed even by fire and shock by the shape and airtight coupling structure of the hinge, emergency escape door bracket, and end bracket of the fire shutter.

And another object of the present invention is to provide a fire shutter that can prevent the opening of the emergency escape door because it automatically locks the emergency exit door of the fire door when the fire occurs.

Fireproof shutter of the present invention for achieving the above object is the hinge hinge coupled to the first hinge bracket and the second hinge bracket is installed between the slat of the fire prevention shutter and the slat of the emergency exit door, the first bracket and the second bracket An emergency escape door bracket is formed between the slats of the fire door shutter and the slats of the emergency door door, and the end of the fire door shutter is installed in the fire end shutters, end brackets, to prevent the easy coupling and deformation between the hinge to the first 2, anti-deformation coupling means formed on the hinge bracket; Reinforcing coupling means formed on said first and second brackets so that said emergency escape door brackets can be continuously hermetically sealed while preventing bending of said escape door bracket; An end bracket coupling means formed on the end bracket so as to be hermetically coupled between the end brackets; The hinge, emergency escape door bracket, characterized in that it comprises a fixed plate mounting means for easy installation of the end bracket.

The embossing (D3) (S3) and the screw (N) formed in (D) were to be fastened.

Therefore, the fire shutter (S) provided with the hinge 100 of the present invention configured as described above is the first and second coupling blocks 250 and 350 and the coupling protrusion 261 ( Since the hinges 100 are coupled and installed by the combination of the 361, the hinge 100 can be installed more easily and conveniently, and thus, the installation of the fire shutter (S) is also easily performed.

In particular, since the present invention forms the second coupling block 350 having the coupling groove 351 formed in the second hinge bracket 300, deformation does not occur in the casting production and cooling process due to the shape of the second coupling block 350. Therefore, in the present invention, when the second hinge bracket 300 is fixedly installed on the slat D1 of the emergency exit door D, as shown in FIG. 5B, the bending hinge S is closely contacted with the bending part D2. It greatly improves the flame retardancy, and because of the second coupling block 350 is not deformed conventional calibration work is unnecessary, and the productivity of the second hinge bracket 300 is also greatly improved.

The emergency exit door bracket 400 illustrated in FIG. 6A is installed to shield a gap between the fire prevention shutter S and the emergency exit door D, and the first bracket 500 and the second bracket 600 are largely installed. , Reinforcing coupling means, fixed plate installation means.

Therefore, the present invention blocks the flow of air as much as possible due to the shape and engagement characteristics of the stepped portions 542 and 642 together with the engaging pieces 511, 611 and the engaging grooves 512, 612. By reinforcing to further improve the flame retardancy of the emergency exit door bracket (400).

In addition, the present invention corrects the coupling tolerance between the slats D1 since the plurality of emergency exit door brackets 400 are more hermetically coupled, thereby preventing the plurality of slats D1 from sagging by their own weight. The deflection phenomenon of (D) is also prevented.

In addition, the present invention is the rounded coupling pieces 511, 611 and the coupling groove 512, 612 is engaged by the engagement, the winding of the fire shutter (S) is made naturally, the operator has a plurality of emergency escape door bracket ( It is possible to simply perform the installation of the emergency exit door bracket 400 by simply combining the 400.

In addition, the emergency escape door bracket 400 of the present invention forms a reinforcement portion 541, 641 having a bent shape as a reinforcing coupling means in the blocking plate 540, 640, so that the fire shutter (S) or emergency escape Even when the door D is shaken or when the emergency exit door D is opened or closed, the blocking plates 540 and 640 are not deformed and the shape and installed state can be firmly maintained. do.

In particular, since the emergency exit door bracket 400 of the present invention is non-directional, the first bracket 500 is installed in the emergency exit door D in addition to the method illustrated in FIG. 6A, and the second bracket 600 is fireproof shutter (S). ) Can be installed, and it can be installed by changing its installation position up and down.

The end bracket 700 illustrated in FIGS. 7A, 7B, and 7C is installed at both ends of the slats D1 of the emergency exit door D to perform reinforcement and flame retardation functions of the slats D1, and the end bar 710. It consists of a fixed plate 720, the end bracket coupling means, a fixed plate installation means.

First, the end bar 710 is installed in close contact with the side of the slat D1 of the emergency exit door D, and the fixing plate 720 is integrally formed at one side of the end bar 710 so that the slat of the emergency exit door D is provided. It is fixedly installed at (D1). In addition, the end bracket coupling means is to ensure that the other end bracket 700 and hermetically and easily coupled, for example, the upper and lower portions of the end bar 710 the round coupling piece 711 and the coupling groove 712 Formed.

The fixing plate mounting means is for fixing the end bracket 700 to the slats D1 of the emergency exit door D. For example, a fixing hole 731 is formed in the fixing plate 720 of the end bracket 700. A plurality of bosses 730 were formed so that the screws N could be fastened with the embossing D3 formed on the slats D1 of the emergency exit door D.

As illustrated in FIG. 7A, the fire protection shutter S having the end bracket 700 of the present invention configured as described above has a coupling piece 711 and a coupling groove 712 having rounded ends at upper and lower ends of the end bar 710. Since it is formed to be easily and hermetically coupled to the coupling piece 711 and the coupling groove 712 of the other end bracket 700.

In particular, the coupling piece 711 and the coupling groove 712 of the present invention is maximized the airtightness of the fire shutter (S) because it blocks the flow of air to the maximum due to the combination of the form of engagement with the characteristics of the round shape. Therefore, in the present invention, as shown in FIGS. 7B and 7C, even when a plurality of end brackets 100 are coupled, almost no gap is generated in the combined portions, thereby significantly improving the flame retardancy of the end bracket 100 and thus leaking smoke. Will be prevented more effectively.
