Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a building having explosion-proof performance with enhanced safety in the event of an explosion.
[0002]
[Prior art]
At a facility such as a gunpowder factory or a nuclear power plant, an accident may cause an explosion inside a building. At this time, in order to minimize the damage, it was common to design the building in the following two ways.
[0003]
(1) The first concept is to construct buildings for explosives and other facilities where the explosion is limited to local damage and does not cause secondary large-scale disasters over a wide area. It is a lightweight structure such as a one-story wooden structure. The idea is that if an explosion occurs inside a building, the building is allowed to be destroyed, and the impact of the blast or flying objects from the blast on the neighboring buildings is minimized. It is based on.
[0004]
(2) The second concept is that for facilities where the explosion may cause a secondary large-scale disaster over a wide area such as a nuclear power plant, The structure is designed to be strong enough to withstand (for example, the outer wall of the building is a reinforced concrete structure with a thickness of several hundred centimeters), and the idea is to prevent the explosion from affecting the outside of the building. It is based on
[0005]
[Problems to be solved by the invention]
On the other hand, in recent years, semiconductor factories and high-tech R & D facilities (hereinafter referred to as “high-tech facilities”) often handle a large amount of explosive substances such as hydrogen gas and monosilane gas, which may cause an explosion accident. Sex is getting higher.
However, in constructing a building of a high-tech facility, the first concept is inappropriate because the building assumes an independent one-story light-weight structure, and in the second concept, Since it is assumed that the building has a strong structure, there is a problem that it becomes uneconomical. Further, in the building of the high-tech facility, there is a demand for a flexible and free change of the building section in response to a change in the production line or a change in the theme of research and development. A proposal is required.
[0006]
The present invention has been made in order to solve the above problems, and has an object to provide a building with improved safety at the time of explosion, which is suitable for various facilities handling explosive hazardous substances. I have.
[0007]
[Means for Solving the Problems]
In order to solve the above problems, the building of the present invention is configured such that an inner area is separated by a partition wall into an explosion-hazardous area that is in contact with an outer wall having a pressure release port in a building frame, and another area. In the building, the partition wall is formed by a plurality of partition plates arranged in a layer so as to surround the pressure release port, the building frame and the partition wall, the pressure release When the mouth is opened, it is formed with a design reference strength that can withstand the maximum pressure acting inside the explosion-hazardous area, and each of the partition plates is provided before the pressure release port is opened. In addition, it is characterized in that it is formed with a design standard proof stress that can be destroyed by the pressure acting inside the explosion hazard area.
[0008]
Here, the explosion-hazardous area is a space where there is a danger of explosion, which handles explosion-hazardous substances inside a building, and refers to a factory work room, a laboratory, or a room where a power generation device is installed. .
In addition, the pressure release port is designed and constructed so that the design standard strength is smaller than the outer wall part, and when it explodes, it is opened earlier than the outer wall part, releasing the indoor pressure to the outside It is a part that plays a role and may be a window or the like.
[0009]
Furthermore, a general plate-like panel material such as a gypsum board or a calcium silicate plate can be used as the partition plate. It is necessary to provide a plurality of partitions, but the number of layers is appropriately determined according to the area of the pressure release port, the strength of the partition used, the type of building, the size of the explosion hazard area, etc. Must be determined. Further, it is not necessary to use the same type of member for all partition plates.
[0010]
In the building of the present invention, the interior area is separated into an explosion-hazardous area and another area by a partition wall formed of a plurality of partition plates arranged in a layer so as to surround the pressure release port. Therefore, by absorbing the explosion energy by destroying the partition plate first, reducing the explosion energy, and then opening the pressure release port, the effect of the explosion will extend to other areas of the building and the outside. The most reasonable (effective and economic) can be prevented.
[0011]
Further, in the building, the partition plate may be arranged so as to be attachable and detachable by a base material.
Here, the base material is a member used for the frame of the partition plate, and may be a member such as a stud, a runner, a steady rest, or the like.
[0012]
ADVANTAGE OF THE INVENTION According to this invention, since a partition board is provided by the base material so that attachment and detachment are possible, installation work of a partition wall can be performed easily and the internal area of a building can be moved flexibly and freely. It can be changed.
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described in detail with reference to the drawings.
In the following description, the same components will be denoted by the same reference symbols, without redundant description.
[0014]
[The concept of the present invention]
FIG. 1 is a graph showing the relationship between the internal pressure of the building 10 and the time that occur with the explosion when the explosion occurs inside the building 10. According to this graph, when the pressure release port 12a communicating with the outside is provided on the outer wall 12 of the building 10, the maximum pressure value inside the building 10 generated by the explosion when the pressure release port 12a is not opened. It is shown that (point A in FIG. 1A) is larger than the case where the pressure release port 12a is opened (point A ′ in FIG. 1B) (B ′). The dot indicates the time when the pressure release port 12a is opened).
Therefore, when an explosion occurs, the pressure release port 12a is opened, and the building frame 12 and the partition wall 13 described later are designed to withstand the above-mentioned maximum pressure value. However, it can be reasonably prevented that the outside area of the building 10 and the other area 30 (the area other than the explosion risk area 20) in the inside area of the building 10.
[0015]
On the other hand, the maximum pressure value can be reduced as the area of the pressure release port 12a is larger, but depending on the building 10, there may be a case where it is not possible to secure a theoretically necessary area due to its structure. If the pressure release port 12a is too large, the effect of the explosion may reach the outside of the building 10.
[0016]
Therefore, in the present invention, before the pressure release port 12a is opened, a plurality of partition plates 14 formed so as to have a design standard proof stress that can be destroyed by the pressure acting inside the explosion-hazardous area 20 are used. The partition wall 13 is provided in a multi-layered manner so as to surround the pressure release port 12a, so that the partition plate 14 is first broken at the time of the explosion, and is reduced by absorbing the explosion energy. 12a is to be opened.
[0017]
However, the pressure release port 12a is designed to break at a pressure slightly lower than the maximum pressure value in the room when the pressure release port 12a is opened (see FIG. 1 (b)) obtained from various tests. Is preferred in order to minimize the effects of external explosions.
In addition, the entire partition wall 13 and the building frame 11 are formed with a design proof stress that can withstand the maximum pressure acting inside the explosion-hazardous area 20 when the pressure release port 12a is opened. The partition plate 14 (indicated by reference numeral 14A) provided at the outer edge on the other area 30 side must be designed so as not to be broken at least by the maximum pressure.
[0018]
[Building]
As shown in FIG. 3, in the building 10 of the present invention, a building frame 11 is constructed on a foundation (not shown). The explosion-hazardous area 20 is separated from the other area 30.
The explosion-hazardous area 20 is in contact with an outer wall 12 of the building skeleton 11, and the outer wall 12 is formed with a pressure dissipation port 12a having a predetermined area.
[0019]
In the present embodiment, the partition wall 13 is provided with a substantially C-shaped four-layer (multi-layer) partition plate 14 so as to surround the pressure release port 12a. As shown in FIG. 5, the partition plate 14 includes a groove-shaped runner 15 provided at the upper end and the lower end in a horizontal direction, and a plurality of studs 16 (H-shaped cross section) provided at predetermined intervals in the vertical direction. Supports the back surface or the front surface. The runner 15 is arranged so that the opening 15a faces up and down. The outside of the flange 16a of the stud is in contact with the inside of the flange 15b of the opening 15a, and the position of the runner 15 is changed. , The partition plate 14 can be attached and detached. Note that reference numeral 17 denotes a slip stopper provided in the horizontal direction.
[0020]
According to the building 10, when an explosion occurs inside the explosion-hazardous area 20, the partition plates 14 having a small design standard strength are sequentially destroyed from the side close to the explosion-hazardous area 20. At this time, the explosion energy is absorbed by the destruction of the partition plate 14, and after the explosion energy decreases, the pressure release port 12a is opened (see FIG. 4). After the pressure release port 12a is opened, the maximum pressure inside the explosion-hazardous area 20 is designed not to increase significantly, so that the effect of the explosion to the outside of the building 10 is suppressed. can do. In addition, since the outermost edge of the partition plate 14 provided on the other area 30 forming the partition wall 13 is designed so as not to be destroyed, an explosion to the other area 30 is prevented. The effect can be suppressed.
Furthermore, since the partition plate 14 is provided so as to be attachable and detachable by the runner 15, the stud 16, and the slip stopper 17, the type and the number of the partition plate 14 are appropriately changed, so that the inside of the building 10 can be changed. The area can be changed flexibly and freely.
[0021]
[Others]
There is no limitation on the cross-sectional shape of the stud 16 for attaching the partition plate 14, and the C type 41 (see FIG. 6A), the mouth type 42 (see FIG. 6B), and the CH type 43 (FIG. 6 (c)) and HH type 44 (see FIG. 6 (d)).
There is no limitation on the arrangement of the studs 16, 41 to 44, and in a plan view, a staggered arrangement (see FIGS. 3 and 6 (a)), a linear arrangement (see FIG. 6 (b)), a substantially S-shape. A zigzag arrangement (see FIG. 6C), an oblique arrangement (see FIG. 6D), or the like can be used. Note that the linear arrangement and the S-shaped arrangement are particularly effective when the strength of the partition plate is high.
[0022]
In the foregoing, an example of the preferred embodiment has been described for the present invention. However, the present invention is not limited to the above-described embodiment, and the design of each of the above-described components can be appropriately changed without departing from the spirit of the present invention.
In particular, the building of the present invention can be applied to various buildings such as factories, laboratories, nuclear power facilities, and the like that handle explosive hazardous substances such as explosives and flammable gas. There is no limitation on the shape of the partition wall.
