Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a fire prevention device for separating upper and lower floors of a building, which is most suitable for buildings, particularly wooden buildings.

(Background Art) Conventionally, for example, in concrete buildings, iron doors are used as fire walls to prevent the spread of fire in the event of a fire.
Such measures to prevent the spread of fire are not taken in the vertical direction of buildings, including wooden buildings.゛Of course, even if a steel firewall is installed, it will be immediately heated by a fire from below, and its effectiveness cannot be expected. Therefore, it is necessary to install a fire prevention wall that can withstand high temperatures and can be installed vertically. materials are difficult to obtain.

Therefore, with the exception of concrete buildings, once a fire breaks out on the lower floors, it is difficult to avoid the fire spreading to the upper floors, which is extremely problematic for the safety of residents on the upper floors, as well as causing losses in the event of a fire. It cannot help but become a huge problem.

(Object of the Invention) The present invention was made in view of the danger and shortcomings in the event of a fire in wooden buildings and other buildings where fire may spread to the upper floors.
The purpose is to install an effective isolation fire prevention device between the upper and lower floors,
The objective is to prevent or significantly delay the spread of a fire to the upper floors, thereby increasing safety and reducing fire losses.

(Structure of the Invention) In accordance with the above object, the present inventors have conducted intensive research and have found that it is extremely effective to install a barrier made of liquid, especially water, between the upper and lower floors of a building, and have completed the present invention. That is, the present invention provides a structure in which a single or a plurality of upper and lower storey shielding walls are interposed across a structure between upper and lower storeys of a building or a space in the vicinity thereof, and the barrier wall is The barrier wall case is made of a large bag-like paper material or laminated with other materials for reinforcement, and water is injected into the barrier wall case after installation. The gist of this is a fire prevention system that isolates the upper and lower floors of a building.

The upper and lower hierarchical barrier walls (hereinafter simply referred to as "shield walls") used in the present invention include a large-sized barrier case made of paper material or laminated and reinforced with other materials, and this barrier case. It is constructed with water injected after it is installed in the building.

Paper-based barrier gates are naturally flammable materials, but paper is used because paper exhibits extremely high fire resistance against flames if a considerable amount of non-combustible liquid such as water comes into contact with it. This is because it will not burn. In other words, the temperature rise caused by flame on paper is prevented by water, which is a nonflammable liquid. However, in materials other than paper, such as synthetic resin materials such as vinyl chloride, as a result of partially shrinking and dissolving due to flame, the pores are extremely short. It is not appropriate to avoid water runoff as it occurs over time.

Therefore, it is essential in the present invention to use a paper shielding case. Since water is naturally injected into this shielding case, it is essential to take waterproof measures to prevent it from leaking.

Waterproofing measures can also be taken by applying or impregnating a waterproofing agent, or by laminating a waterproof material 1, such as a synthetic resin sheet, on the inside. At this time, if reinforcement is required to ensure transportability, installation workability, or damage prevention because it is made of paper, cover and laminate a synthetic resin sheet on the outside, or laminate a cloth sheet, etc. on the inside. Waterproofing and reinforcing measures may be taken at the same time, whether on the inside or outside. However, care must be taken in this case as using a water-resistant material on the inside will cut off the contact between the paper and water.

Further, depending on the amount of water to be injected, a frame, a support plate, a support case, etc. may be further installed inside or outside the bag-shaped barrier case. In this case, if you install this on the inside, for example, with wood, you can prevent the frame from burning in the event of a fire by impregnating the injected water and causing the shielding case to fall immediately. This is desirable because it allows you to receive most of the above. Also, when installing this on the outside, if you install a plate-shaped or mesh-shaped support plate made of metal material such as iron, the water-filled barrier will prevent the temperature from rising. Alternatively, the shielding wall can function to prevent or significantly delay the spread of fire to the upper floors. Of course, if a support case made of water-resistant material is installed inside, the barrier case will be cut off from contact with water, so there is no point, and even if a through hole is provided, the water load will not be applied to the barrier case. On the other hand, it is also undesirable to provide them on the outside with a material such as synthetic resin that burns immediately and emits toxic gas when burned. In addition.

It is better to set the frame on the outside, but in this case it may be in the form of a grid, but in the case of combustible materials, the combustion of the
Since all of the water load will be applied to the shielding case, it is necessary to consider reinforcing the shielding case itself.

The shielding case may of course be one that is close to the building area that traverses the entire surface of the building integrally, but in this case, the load of water must be taken into consideration, especially by reinforcing and supporting the shielding case. Therefore, for example, it may be made long enough to cross in one direction, or it may be separated into multiple pieces, but in either case, it is desirable to have sufficient length and reinforcement. . However, for example, to make each structural member of a wooden building the minimum unit perpendicular to each other, or a size close to this, is
As will be described later, it is complicated and undesirable to install and inject water.

An injection port is provided in the shielding case. If this is not used alone, but in plural, it is necessary to provide respective communication holes or to connect them with pipes so that the injected water can spread throughout. For this reason, it is not desirable to divide the tube too much even after water is injected.

The injection port is sealed after injection, and this can be done, for example, with a cap. Moreover, when the pipe is used, it is preferable to make the distance between the pipes as short as possible so that when the pipe is separated into the plurality of parts, the space between the pipes does not open during installation.

Further, it is more desirable that the shielding case is provided with a fixing edge or ear at the upper end if possible, and is provided with means for fixing it to the building using nails, staples, or the like. Of course, this fixing means can also be provided between a frame, a support case, etc. when these are used.

Furthermore, it is naturally possible to provide a water drain in the shielding case so as to be able to deal with subsequent situations such as the occurrence of problems regarding the strength of the building or water replacement.

A barrier case is used when constructing a new building or increasing the number of buildings.
It is interposed in a single or multiple ways across the lower interlayer structure or neighboring space. The former is, for example, a wooden frame structure (when the orthogonal structural members are arranged vertically in a circle to create a continuous space in one direction, and the latter is a flat space where the shielding wall case is installed continuously). In the latter case, it is better to lift up these structural members and create this space near the lower level.However, in this case, it is necessary to separately provide a horizontal structure to support the ceiling of the lower floor. coming out.

In addition, in the case of curved wood, the upper structural material is also exposed to the flames, but in this case, if it is installed so that the flame hits the wooden wax surface, it will be very difficult to burn, so this part should not be exposed. There is no need to pose a particular problem.

If possible, provide a fixing means to the building, especially a nearby structural material, to this shielding case, and also provide the above-mentioned supporting means necessary during installation.

Ordinary tap water is sufficient as the water injected into the shielding case, but a preservative may be added to it, for example. In addition, rather than 100% injection, it is sufficient to fill 70 to 80% in the vertical direction, and it is usually desirable to perform this using a pressure pump. In addition, when using a plurality of shielding wall cases, it is necessary to take care that water sufficiently spreads through all of them.

To further explain the present invention with reference to the drawings, reference numeral 1 denotes a shielding case, and this shielding case 1 includes a paper material part 2 coated with a waterproofing agent on the outside, a vinyl chloride sheet 3 on the outside, and a woven fabric on the inside. The cloth sheets 4 are laminated and made of a material that is integrated into a bag-like and long shape, so that the cloth sheets 4 are large in the longitudinal direction.

The upper part of the shielding case 1 has an edge part 5.5 extending from the edge part 5.5 and injection ports 6 provided in each of the shielding cases 11cI. Reference numeral 7 in the figure denotes a lid that closes the upper opening, and the four corners of the shielding case 1 are covered in the same way.

On the other hand, 8 is a support case made of iron plate, and this support case 8 includes a F plate-shaped support part 9 and two parts 10.
It is integrally constructed with.

In addition, numerals 11 in the figure are through holes for nailing.

Reference numeral 12 denotes a structure between the upper and lower floors of the building, and this structure rWt2 consists of structural members 13 and 14, which can be seen in a general wooden framework structure, intersecting each other in an upper and lower rrC pattern, and one structural member 13. It has a continuous space 15 between the two sides.

In this continuous space 15, as shown in FIG.
6, and are placed and fixed on the lower structural members 14, 14... A shielding case 1 is provided on this support case 8, and is fixed together with splints 17.17 continuous in the longitudinal direction by nailing the extending edge 5.5.

Reference numeral 18 denotes water injected into this shielding wall case 1 from the inlet 6. After the water 18 is injected, the inlet 6 is sealed with a camp 19 attached thereto.

Note that 20 in the figure indicates the floor of the upper level.

Although this embodiment has been constructed as described above, it goes without saying that the present invention can be implemented in various specific shapes, structures, etc. without departing from the gist thereof.

(Effects of the Invention) In the present invention, a single or multiple upper and lower storey shielding walls are interposed in the structure between the upper and lower storeys or the space in the vicinity thereof, so that the upper and lower storeys are blocked by this barrier. At this time, even though some of the ends of the structural materials may be exposed, it is difficult for the ends to burn if the flames reach the sides, and the above-mentioned shielding wall exists for the parts other than the structural materials. Even if a fire breaks out in the lower floors, will it be possible to prevent the fire from spreading to the upper floors?
Alternatively, it is possible to significantly delay this.

In addition, the shielding case is made of paper in the form of a large bag, or is made of paper laminated with other materials for reinforcement.

Since it is made by injecting water into the interior and sealing it, it can be obtained at a relatively low cost, and it is easy to adapt to the installation location, making it suitable for fire prevention in upper and lower floors. In addition, even if it is damaged, it is harmless and will not accelerate the fire, even if it is a non-flammable liquid such as water, so if you use a large amount of it, it may be somewhat effective in extinguishing a fire. do not have.

Furthermore, since the shielding wall case is designed to be filled with water, it is relatively easier to handle and install on-site than installing a case that contains this in advance, and does not require costly tools or construction work.

As described above, the present invention has the effect of simply and reliably preventing or delaying the spread of a fire on a lower floor to an upper floor, and allowing sufficient rescue of lower floor occupants and firefighting activities during this time.
