Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to areas where there is a risk of fire spreading in external openings of buildings, boundaries between atriums, escalators, and store areas, or fire prevention passageways in large stores. This invention relates to a fire safety compartment system that can be shielded with transparent fire glass without impairing the design effect.

[Conventional technology] Conventionally, as a fire prevention measure for buildings, fire shutters, fire prevention partitions such as plasterboard, and steel fire doors were installed at external openings and atrium vertical openings where there was a risk of fire spreading. We are trying to prevent this.

For example, as a fire prevention measure for an opening in an exterior wall where there is a risk of fire spreading, as shown in FIG. 8, wired glass 1 is provided in the opening in the exterior wall, and a fire prevention shutter 2 is provided outside of the wired glass 1. Furthermore, a partition wall 4 is provided inside the wired glass l through a passage 3 to form a fireproof section of the room 5.

As a fire prevention measure for the opening of the vertical hole compartment in the atrium space,
As shown in FIGS. 9 and 10, a vertical hole compartment opening is provided facing the atrium space 7 below the top light 6, and a fire protection shutter 2 is provided in the opening. A store 8 is located inside the fire shutter 2 through a passage 3, and the passage 3 and the store 8 are separated by a show window glass 9.

[Problems to be Solved by the Invention] As a conventional fire prevention measure for buildings, fire doors and partition walls are provided in partition walls for fireproof divisions, but in such configurations, the partition walls are not transparent. Because there is no space, the space tends to be heavy and oppressive in terms of design. Furthermore, fire shutters and fire doors that are supposed to have the ability to block the spread of fire actually have poor heat blocking performance, which increases the risk of fire spreading to other rooms, and the current situation is that they do not perform their functions satisfactorily.

In addition, when shutters and partition walls were provided for fireproof divisions, there was also the problem that the indoor space became narrower.

Therefore, the present invention uses foamable fireproof glass that has heat and flame blocking properties and installs it in openings etc. where there is a risk of fire spread, thereby freeing up space without using conventional fireproof shutters or partition walls. The purpose is to use the system more safely and effectively, and to make it more desirable both in terms of design and for confirming evacuation destinations due to its transparency.

[Means for Solving the Problems] The present invention is a fire safety compartment system that achieves the above objects. This system attaches foam fireproof glass to openings in the exterior walls of buildings where there is a risk of fire spreading, and allows the room to be used more widely without having to install partition walls to block the spread of fire inside the foam fireproof glass. . We also made it possible to obtain transparency and design effects through the foamed fireproof glass.

When providing a fire protection section at the opening of a vertical hole section such as an atrium space, a store is provided inside the outer wall opening via a passage,
The aisles and stores will be separated by foamed fire-retardant glass. The transparency of the foamed fireproof glass provides a design effect and visibility.

When dividing a part of an escalator in a large store, fire passageway, or evacuation room of a building into a fireproof zone, if you divide the area with foam fireproof glass, you can create a fire safety zone system with good design effects and visibility. .

[Function] In the above-mentioned fire safety compartment system, the areas where fire doors, fire shutters, etc. are installed are separated by foamed fire glass, so there is no need to separately provide fire doors or fire shutters. In addition, foamable fireproof glass has heat-insulating properties and flame-blocking properties, so there is no need to install additional partition walls.
It does not reduce interior space.

When foamable fireproof glass receives heat during a fire, the foaming agent forms a foam layer, thereby providing sufficient heat shielding properties. In addition, since foamed fire-retardant glass is normally transparent,
It is possible to see the opposite side across it, improving the design effect, and also being able to see the situation ahead when evacuating in the event of a fire, allowing for safe evacuation.

[Example] A first embodiment of the present invention will be described with reference to FIG.

This embodiment is a fire protection safety partition system for external openings of buildings where there is a risk of fire spread, and the windows of the external openings of chambers 11 are constructed of foamable fireproof glass 12. The foamable fireproof glass 12 has a transparent sodium silicate-based foaming agent, aluminum phosphate-based foaming agent, etc. bonded between multiple sheets of glass, which foams and becomes cloudy due to the heat of a fire. Since it is a layer, it has sufficient heat shielding properties. Furthermore, the foamable fireproof glass 12 has high transparency like normal glass at room temperature, so it is possible to see the situation on the other side through it.

Intumescent fire-retardant glass 12 in external openings of buildings as described above.
If you provide a
Unlike the conventional example (see FIG. 8), there is no need to provide a partition wall, and the room can be used widely and effectively. In addition, since foamable fireproof glass has transparency, it is possible to see the other side of the glass, and furthermore, it is possible to obtain a design effect.

Next, a second embodiment of the fire safety compartment system applied to the vertical hole compartment opening of the atrium space will be described with reference to FIG. 2.3.

In this embodiment, a store 15 is provided inside the vertical hole compartment opening of the atrium space 13 via a passage 14 . The passageway 14 and the shop floor 15 are separated by foamable fireproof glass 12 which serves both as a show window and a firewall. Unlike the conventional example (see Fig. 9), a shutter is not provided between the atrium space 13 and the passageway 14 (it is left open, allowing daylight and ventilation from there. An openable/closable door 16 made of foamed fireproof glass is provided in a passageway located away from the entrance.

As described above, the foamable fireproof glass 12 for disaster prevention also serves as show window glass, so it is possible to create a space that is excellent both in design and functionality. Furthermore, fire protection on the store side can be achieved by the foamable fireproof glass 12 without providing a shutter between the atrium space 13 and the passageway 14. Therefore, both in normal times and in the event of a fire, the space between the atrium space 13 and the passageway 14 can be seen from either side, which not only provides a design effect, but also allows for confirmation of safe evacuation routes and appropriate fire prevention activities. .

Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, the escalator section of a large store or the like can be separated from surrounding store sections as a fire prevention section. Both sides of the escalator part 17 and the store part are separated by foam fireproof glass 12, and the escalator part 1
Fireproof shutters 18 were installed before and after from 7. In addition, the portions where each foamable fireproof glass 12 is adjacent to the shutter are formed into fire doors 19 that can be opened and closed.
7 is made using foamed fire-retardant glass.

Therefore, in the event of a fire, if the shutters 18 at the front and rear of the escalator section 17 are closed, the escalator section 17 becomes a fireproof section. Since the foamable fireproofing glass 12 on both sides of the escalator portion 17 is transparent, it is possible to obtain a design effect in the store during normal times, and in the event of a fire, it is possible to evacuate while observing the situation through the foamable fireproofing glass. In this way, both sides of the escalator part 17 are covered with foam fireproof glass 1.
2, it becomes possible to create a functional design by removing handrails and the like in the vertical hole area of the escalator part 17.

Next, a fire safety zone system in a shopping center will be explained with reference to FIG. In this embodiment, a separation strip and a passage 21 are provided between each exhibition corner 20, the separation strip is formed of foamed fireproof glass 12, and a door 22 is provided at the appropriate location. Shutters 23 are provided at both ends of the separation strip, and the shutters 23 are normally open.

By creating fireproof divisions in this way, each exhibition corner 20 can be divided aesthetically and functionally using transparent fireproof foam glass 12. Moreover, since fireproof foam glass 12 can serve as a firewall, the area of the shopping center can be reduced. can be used effectively.

Next, referring to FIG. 6, a fire safety zone system for evacuation routes of buildings will be explained. In this embodiment, an openable and closable fireproof glass door 25 made of foamable fireproof glass 12 is provided in the passageway 24. and 5 evacuees 2 during the fire
6 can see the situation in the fire room 27 through the fireproof glass door 25, so they can evacuate while accurately grasping the safety of the evacuation direction.

Next, a fire safety compartment system for indoor space will be explained with reference to FIG. In this embodiment, an indoor space 28 is divided by a fireproof partition wall 29 made of foamable fireproofing glass 12, and its transparency creates a bright (comfortable) divided space, and in the event of a fire, the foamable fireproofing glass protects against fire. Since it becomes a wall, a safe fireproof compartment can be secured.

[Effects of the Invention] According to the fire safety zone system of the present invention, it is possible to create a fire wall made of foamed fire prevention glass that has transparency, heat insulation and flame insulation properties, or a fire prevention wall that also serves as show window glass, etc. It is possible to create a bright and comfortable space with excellent design and functionality without installing fireproof shutters, fireproof doors, or fireproof partition walls. Since there is no need to separately provide a firewall and space can be used effectively, construction costs can also be reduced.
