Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to a shutter device with a door mechanism having a shutter curtain provided with a door mechanism, and can be used, for example, for a disaster prevention shutter device for performing fire prevention, smoke prevention, and the like. It can be suitably used as a shutter device for a large opening that partitions.

[0001]

2. Description of the Related Art Generally, shutters for various purposes for moving a shutter curtain up and down to partition a space are provided at entrances and exits of a building or in the middle of a passage, for example, for fire prevention and smoke prevention. Disaster prevention shutter devices are one of them.

Heretofore, as such a disaster prevention shutter device, a device provided with a metal (iron) shutter curtain has been used. The disaster prevention shutter device equipped with a metal shutter curtain has a width based on the Ministry of Construction notification (Notification 2564, 1972) based on Article 112, Paragraph 14, Item 4 of the Building Standards Law Enforcement Order. Is 5 m or less as a standard specification. Therefore,
In the case of a so-called large opening where the opening in the building where the disaster prevention shutter device is to be installed (the cross-sectional width of the space to be partitioned by the shutter curtain) is so-called, a center pillar provided with a guide rail in the middle position of the opening is usually used. By standing,
A disaster prevention shutter device of standard specifications with a width of 5 m or less was provided continuously.

[0003] Further, a disaster prevention shutter device is used to secure an evacuation route for people in a building in the event of an emergency such as a fire, that is, after a shutter curtain is lowered due to a fire or the like, the disaster prevention section is provided. It is necessary to provide an emergency doorway in order to secure a way for those who are left inside.

Conventionally, in a disaster prevention shutter device having a metal shutter curtain, it is relatively difficult to provide such an emergency doorway in the shutter curtain itself. To
Aside from that, there was often a sleeve door dedicated to emergency entrances.

On the other hand, in recent years, the development of various materials has progressed, and cloth screens having excellent fire resistance, heat shielding, smoke shielding, waterproofing, and the like have been developed, and shutter curtains formed by such cloth screens have been developed. The disaster prevention shutter device provided has been used with the approval of the Minister of Construction under Article 38 of the Building Standards Act.

[0006] Such a cloth screen can be sewn and easily secured, so that an emergency doorway can be easily provided in the shutter curtain itself. Disaster prevention shutter devices in which an emergency entrance is provided in a shutter curtain itself formed by a screen have come to be used.

[0007]

However, the provision of an emergency doorway in the shutter curtain itself is not limited to the case of a shutter curtain formed by a cloth screen, but also includes the case of a metal shutter curtain. There are various issues to consider:

That is, first, since an emergency doorway is provided in the shutter curtain itself, it is structurally more complicated than a shutter curtain in which no emergency doorway is provided. It is necessary that the original function of the shutter curtain to be partitioned and closed is not obstructed. Therefore, when providing an emergency doorway on the shutter curtain itself,
It is necessary to avoid the complication of the configuration as much as possible and to make the shutter curtain smoothly closed so as to exhibit its original function.

Next, in the shutter device for disaster prevention, the shutter curtain is required to have smoke shielding performance, and is also required to have wind resistance. Therefore, it is necessary to secure the airtightness and to secure a certain strength.

Further, since an emergency doorway is provided in the shutter curtain itself, it takes more time and effort in manufacturing than in the case of manufacturing a shutter curtain having no emergency doorway. It is desired that the arrangement be as easy as possible to facilitate the manufacture.

[0011] After the production, the transport work to the construction site and the construction work at the construction site are performed. Therefore, it is necessary to facilitate the handling during transportation and construction.

[0012] The above-mentioned problems relating to the arrangement of the emergency entrance are as follows. The larger the opening in which the shutter device is to be installed, that is, the wider the shutter curtain, the more the problem.
Since this is a significant problem, it is particularly closely related to the problem of coping with the large aperture described below. Further, not only the shutter device for disaster prevention but also a shutter device having another purpose is a problem that similarly occurs when an entrance or the like is provided in the shutter curtain itself.

Further, there are various sizes of spaces in a building, and accordingly, the width of an opening where a disaster prevention shutter device is to be installed is also various in size. Therefore, when installing the disaster prevention shutter device, it is necessary to cope with a large opening, but in that case, there are the following problems.

That is, a disaster prevention shutter device provided with the above-mentioned metal shutter curtain and having a width of 5 m
If a plurality of the following standard specifications are prepared, and they are connected in series to accommodate a large opening, the middle pillar with the guide rail must be set up at the middle position of the opening, which creates a large space. For example, there are many restrictions on architectural design, and the appearance is also unfavorable.

On the other hand, in the case where the Minister of Construction approves according to Article 38 of the Building Standards Act, even a disaster prevention shutter device having a metal shutter curtain having a width exceeding 5 m can be used. By installing one such wide disaster prevention shutter device, it is also conceivable to cope with a large opening.

However, in the case of a metal shutter curtain, if the width is increased, the weight increases, and handling during transportation, construction, or manufacturing becomes difficult, and particularly, the shutter curtain has a width exceeding the standard specification. In shutter curtains it is noticeable.

The problem of dealing with the large aperture as described above is not limited to the shutter device for disaster prevention, but also in the case of a shutter device having another purpose, when a space having a large sectional width must be partitioned. A similar problem arises.

A main object of the present invention is to provide a shutter device with a door mechanism which can simplify the structure of a shutter curtain, easily secure required functions, and facilitate manufacturing.

An additional object of the present invention is to provide a shutter device with a door mechanism which can appropriately handle one or more of handling during transportation and construction and handling of a large opening. Is to provide.

[0020]

According to the present invention, there is provided a curtain body for partitioning a space, a communication portion for communicating the space between the front and back of the curtain partitioned by the curtain body, a door mechanism for covering the communication portion and a door portion together with the communication portion. In a shutter device with a door mechanism provided with a shutter curtain having a covering portion to be configured, the shutter curtain is configured by assembling each curtain partition portion in a state of being divided into a plurality of partitions, and at least a space is provided by the shutter curtain. In the curtain closed state, each curtain section is connected to each other by a connecting portion, and at least the communicating portion of the door mechanism is located at a position avoiding the connecting portion of the shutter curtain in the curtain closed state. It is characterized by being arranged.

Here, in terms of structure, openings having various shapes such as a square, a rectangle, a triangle, a trapezoid, an M block cross section, an inverted home base, a circle, an ellipse, and a semicircle are formed. Shape or slit shape. In terms of application, emergency exits used for emergency evacuation in the event of a fire, etc. can be cited as main ones. Doorways used, doors exclusively for pets such as dogs and cats, or mere viewing windows that do not assume the entrance of people or the passage of objects (for checking the situation behind the shutter curtain, for example, a shutter device for disaster prevention) In the case of (1), the status of smoke generation and the progress of fire are checked through the shutter curtain). Note that the term “entrance / exit” in the present application includes not only a case where entry / exit and / or passage through both directions are possible but also a case where entry / exit and / or passage only through one direction are possible.

The cover may be formed of a separate member from the curtain body (for example, in the case of FIG. 1 described later), or may be formed integrally with the same member as the curtain body ( For example, the case of FIG. 12 described later). When the cover is formed of a separate member as in the former, the cover may be attached to the curtain body by, for example, fastening with a fastening tool such as sewing, bonding, rivets, bolts, nuts, screws, and welding. , Fastening using fasteners, buttons, or Velcro, etc. are optional.Furthermore, it may be a detachable attachment or a sliding door type that can slide up, down, left and right, etc. In short, a covering part or curtain The mounting method may be determined according to the material of the main body or the installation purpose of the shutter device such as whether or not it is necessary to secure airtightness. In both cases where the former is formed by a separate member and the latter is formed integrally, a configuration may be adopted in which a cover is provided with a key so that the cover is not opened. In addition, a mark or a character indicating the presence of the communication portion (for example, in the case of a disaster prevention shutter device, the presence of an emergency entrance) may be provided on the surface of the cover portion.

Further, when focusing on only one side of the front and back of the curtain, the most basic structure of the door mechanism is constituted by one communicating portion and one covering portion (for example, as described later). However, the present invention is not limited to this, and one door mechanism may be configured by a plurality of communicating portions and one covering portion (for example, FIG. 8 described later).
, Etc.), one door mechanism may be configured by one communication part and a plurality of covering parts (for example, in the case of FIGS. 9 and 10 described later), and a plurality of communication parts and a plurality of And one cover mechanism (for example, in the case of FIG. 11 described later). In the case where one door mechanism is constituted by a plurality of cover portions in each of the above-described patterns, the plurality of cover portions are combined to form a whole or substantially the entire communication portion (however, the shutter device for disaster prevention). In the case of, it is preferable that the entirety be completely covered.) It is sufficient that the entirety or the entirety of the communication part is covered. It doesn't have to be. Therefore, when focusing on one covering portion, at least a part of the communication portion may be covered (see FIGS. 9, 10, and 11 described later).

In configuring one door mechanism, the cover may be provided on only one side of the front and back sides of the shutter curtain, or may be provided on both sides (for example, in the case of FIG. 2 described later). Further, it may be provided so as to enter into the communication part (for example, in the case of FIGS. 9 and 10 described later).

Further, the overlap portion between the covering portion and the curtain body may or may not be provided. However, in the case of a disaster prevention shutter device, it is easy to secure airtightness. From the viewpoint, it is desirable to provide an overlap margin portion.

"At least in a curtain closed state in which a space is partitioned by a shutter curtain" means that in a curtain closed state (a state in which an opening is closed by a shutter curtain), each curtain section is connected by a connecting portion. It is sufficient if it is in a state, other states, for example, a curtain storage state in which the shutter curtain is stored in the storage unit, or a state in the middle of closing, further, a state when the shutter curtain is attached to the shutter device, Regarding the state at the time of transportation from the factory to the construction site, it does not matter whether or not the curtain sections are connected to each other by the connecting section.

[0027] Further, "the state of being connected by the connecting portion" means that the curtain sections (usually, the edges thereof) are releasably connected by fasteners, Velcro, reinforcing bars, or the like. In addition to the state in which the curtain sections are joined by sewing, bonding, welding, or the like, the state in which the curtain sections (usually, the edges thereof) are merely overlapped is also included.

In the case where a plurality of door mechanisms are arranged, it is not necessary that the communication sections for all the door mechanisms are arranged at positions avoiding the connection sections. The portion may be arranged at a position avoiding the connection portion. However, it is preferable that the communication parts for the majority (more preferably all) of the door mechanisms are arranged at positions avoiding the connection parts.

In the present invention as described above, when the door mechanism is provided on the shutter curtain having a configuration in which the curtain sections are connected to each other by the connection part in the closed state of the curtain, when the door mechanism is provided, Since at least the communication portion is arranged at a position avoiding the connection portion, the configuration of the shutter curtain is simplified.
For this reason, the inconvenience that the movement of the shutter curtain is hindered due to the complication of the configuration is avoided beforehand, and the shutter curtain is smoothly closed, so that its original function can be exhibited. In addition, since it is arranged at a position avoiding the connection part, it is easy to secure necessary functions such as smoke shielding performance and curtain strength, and it is possible to facilitate the production.

Further, since the shutter curtain is constructed by assembling the curtain sections divided into a plurality of sections, it is possible to easily cope with a large opening, thereby achieving the above object. Achieved.

Further, in the shutter device with the door mechanism described above, it is preferable that the cover portion of the door mechanism is disposed at a position avoiding a connection portion of the shutter curtain in the curtain closed state.

Here, when a plurality of door mechanisms are arranged, it is not necessary that the cover parts for all the door mechanisms are arranged at positions avoiding the connection parts, and at least one door mechanism is provided. It is only necessary that the cover part is arranged at a position avoiding the connection part. However, it is preferable that the covering parts for the majority (more preferably all) of the door mechanisms are arranged at positions avoiding the connection parts.

As described above, in the case where the cover element as well as the communication part is disposed at a position avoiding the connection part, the structure of the shutter curtain is further simplified, and The required functions can be easily secured and the manufacturing can be further facilitated.

Further, in the above-described shutter device with a door mechanism, when the shutter curtain is stored in the storage section in the curtain storage state, each curtain section may be in a state where they are not connected to each other by the connection section. (For example, in the case of FIG. 1, FIG. 6, FIG. 7, etc., which will be described later), or even in a curtain storage state in which the shutter curtain is stored in the storage section, the respective curtain sections are in a state of being connected by the connection section. This may be performed (for example, in the case of FIG. 5 described later).

In the above, the installation purpose of the shutter device with the door mechanism of the present invention is arbitrary. For example, a shutter device for disaster prevention for fire prevention, smoke prevention and the like is mainly mentioned, but is not limited to this. Not a dark room,
It may be a shutter device for forming a special space such as a clean room, a cold storage room, a heat insulation room, a shutter device for shielding sunlight, a shutter device for crime prevention, etc. In short, it is useful to provide a door mechanism on a shutter curtain. Any shutter device may be used.

Further, the installation place of the shutter device with the door mechanism of the present invention is arbitrary, for example, a general ordinary house,
Various types of buildings, such as shutters for various entrances and exits of buildings, garages, factories, warehouses, cool storages, etc., shutters for windows, shutters installed in the middle of a passage in a building or at the boundary between a passage and a hall, etc. The shutter device may be provided, or may be a shutter device provided in various structures such as an underground mall, a station premises, a tunnel, a ship, and the like.

The structure of the shutter device with a door mechanism of the present invention is arbitrary as long as the shutter curtain can be provided with a door mechanism. Therefore, the present invention can be applied to the following various types of shutter devices. For example, a shutter device in which a shutter curtain is formed using a sheet-shaped member, and this shutter curtain is wound around a winding shaft or folded and stored in a storage unit may be used. The shutter device may be formed by connecting the shutter curtains, and the shutter curtain may be wound around a winding shaft of a storage unit and stored. Further, the shutter curtain is formed by connecting a plurality of panels, and the individual panels of the shutter curtain are separated and stacked and stored in the storage unit, or the individual panels are folded and stored in a connected state. Alternatively, a shutter device of a type that is wound up and stored may be used. Furthermore, the shutter device may be a shutter device in which the shutter curtain is formed by a plurality of pipe members connected to each other by a link member, or may be an overhead type shutter device for feeding and storing. Also, for example, a shutter device of a type including a shutter curtain formed by combining various shutter curtains, such as a shutter curtain partially formed of slats and the remaining portion formed of a sheet-shaped member. May be. The materials of the components and components of the various shutter curtains described above are arbitrary. If the material is a sheet-like member, for example, a screen made of cloth, or a soft resin sheet such as vinyl chloride or urethane, or rubber. Alternatively, a sheet or the like formed of a rubber-like substance can be used, and as long as it is a slat, panel, link member, pipe member, or the like, for example, metal, synthetic resin, ceramics, wood, or the like can be used.

The moving direction of the shutter curtain, that is, the opening / closing direction when the shutter curtain performs the opening / closing operation (the closing direction when performing only the closing operation) is, for example, a vertical direction, a horizontal direction, an oblique direction, a horizontal direction, or the like. Is optional. However, in the case of a disaster-prevention shutter device, it is preferable to set the direction so that it can descend by its own weight.

Further, as described above, the materials of the components and members of the shutter curtain are arbitrary, but it is particularly preferable to make the following. That is, in the above-described invention, it is preferable that both the cover portion and the overlapping margin portion of the curtain body that overlaps at least the cover portion are formed of a sheet-like member.

Here, the sheet-like member may be a cloth screen, a vinyl sheet, a urethane sheet, a rubber sheet, or the like.
Any type may be used as long as it is flexible,
When used for disaster prevention purposes such as fire prevention and smoke prevention, for example,
A silica cloth or a glass cloth, or a material obtained by spraying, applying, or impregnating a fire-resistant paint or a waterproof coating material as a fire-resistant coating material onto these materials can be suitably used. Further, the sheet-shaped member may be combined with a reinforcing metal such as a wire mesh or a resin wire, or the like. Even in this case, the sheet is less likely to be damaged, and the durability of the sheet can be improved, which is effective.

The present invention can be suitably applied to a shutter curtain including a sheet-like member as described above, because a sheet-like member such as a cloth screen is lighter in weight than a metal shutter curtain. This is because folding is also possible, which facilitates handling during transportation, construction, or manufacturing. For this reason, the shutter curtain formed including the sheet-like member,
It is suitable for a wide shutter curtain, and its advantage increases as the width of the curtain increases.
In addition, since it is a sheet-like member, sewing and the like can be performed,
Compared to a metal shutter curtain, it is more suitable for providing a door mechanism structurally, and it is easier to secure airtightness than a metal shutter curtain. Therefore, the shutter curtain including the sheet-like member is most suitable for configuring a disaster prevention shutter device corresponding to a large opening.

As described above, the purpose of installing the shutter device with a door mechanism of the present invention is arbitrary, but it is particularly preferable to perform the following. That is, in the above-described invention, it is preferable that the shutter curtain has a disaster prevention function, and the communication part is an emergency entrance.

Here, the disaster prevention function means at least one of various performances such as fire prevention performance, fire resistance performance, smoke prevention performance, smoke prevention performance, heat insulation performance, waterproof performance, wind resistance performance, and the like. What you can do.

As described above, the present invention can be suitably applied to the disaster prevention shutter device because the disaster prevention shutter device includes:
This is because it is originally required to provide an emergency doorway for securing an evacuation route for evacuees, so that the effect of the present invention regarding the arrangement of the door mechanism is sufficiently exhibited.

Further, in the above, in the shutter device with the door mechanism of the present invention, the inner dimension in the width direction of the shutter curtain is arbitrary, but the following is particularly preferable. That is, in the invention described above, the shutter curtain preferably has an inner dimension larger than a standard inner dimension in the curtain width direction, and is a shutter shutter for a large opening that partitions a space having a large cross-sectional width. .

Here, the inner dimension means the guide means (for example,
The width of a portion excluding a portion swallowed by a guide rail or a groove formed directly on a wall or a pillar), that is, the width of a portion exposed to the outside (a portion viewed from a space partitioned by a shutter curtain). Note that the curtain width direction refers to a direction perpendicular to the direction in which the shutter curtain moves in a plane along the shutter curtain, and the thickness direction (thickness direction) of the shutter curtain.
It does not mean.

The shutter shutter for a large opening is
It satisfies at least one of the following conditions.

As the first condition, a notice of the Ministry of Construction based on Article 112, paragraph 14, item 4 of the Building Standards Law Enforcement Order (Showa 4
8 year notice 2564) "
That is, it is mentioned that the inner width exceeds 5 m (larger than the standard specification of so-called iron fire and smoke prevention shutters).

As the second condition, a notice from the Ministry of Construction based on Article 112, paragraph 14, item 4 of the Building Standards Law Enforcement Order (Showa 4
8 year notice 2564) "
That is, the inner width is more than 8 m (larger than the iron shutter provided adjacent to the position of the type B fire door).

The third condition is that the Road Law
The length of the vehicle (if cargo is loaded, in that state, in that state) specified by a Cabinet Order based on the Clause (Vehicle Restriction Ordinance, Article 3, Paragraph 1, Item 4, Cabinet Order 375 as amended in 1993) , That is, the total width dimension in the curtain width direction exceeds 12 m.

The fourth condition is that the Road Law, Article 47, Section 1
A semi-trailer or full-trailer coupled vehicle that travels on a national highway specified by a Cabinet Order (Article 3, Paragraph 3 of the Vehicle Restriction Order, Cabinet Order 375 of the Last Amendment of 1993) based on the above paragraph, and the loaded cargo is towed That do not protrude beyond the front or rear of the car body, exceed the maximum length, that is, the full width dimension in the curtain width direction is 16.5 m (when mounted on a semi-trailer-connected vehicle) or 18 m (load on a full-trailer-connected vehicle) Case).

A fifth condition is that the total width of the inner dimension in the curtain width direction is about three times or more, preferably about six times or more, the width of the door mechanism. Here, the reference value of about three times is obtained when a door mechanism is provided one at each end of the shutter curtain in the inner direction, and a door mechanism non-installed portion having the same size and width is secured between them. This is based on the fact that when it is more than such a value, it can be regarded as a shutter shutter for a large opening. In addition, the reference value of about 6 times means that a door mechanism is provided one by one at a distance corresponding to the width of the door mechanism from both ends of the shutter curtain inwardly, and a similar dimension width (door) is provided therebetween. This is a numerical value obtained when a door mechanism non-installation part having a width equal to two widths of the mechanism is secured, and if it exceeds this value, it can be regarded as a shutter shutter for large aperture It is.

The sixth condition is that, when the shutter device with the door mechanism of the present invention is a retractable shutter device in which the shutter curtain is wound and stored on a winding shaft, the winding shaft may be in the axial direction. Is divided into two or more. In addition, after being manufactured in a divided state and transported to the construction site in the divided state, it is connected at the construction site to form a single shaft, manufactured in a divided state, connected at the factory and connected After being transported to the construction site in the form of a single shaft, after being manufactured integrally as a single shaft, cut and divided at the factory, and then transported to the construction site , Again connected at the construction site to form a single shaft, manufactured in a divided state, transported to the construction site in the divided state, and used continuously in the divided state at the construction site (In this case, the axis positions of the axes may be matched or may be shifted in parallel.
In this case, the shutter curtain is also a split type,
A configuration may be adopted in which the shutter curtains in the divided state are connected by fasteners or the like at the time of closing the shutter curtain, or are simply overlapped and connected. ) And the like are included.

A seventh condition is that the shutter device with the door mechanism of the present invention is a retractable shutter device that retracts and stores a shutter curtain around a winding shaft. At least at one of the intermediate positions, there is provided a take-up shaft and a support means such as an auxiliary roller for supporting the shutter curtain wound around the take-up shaft and suppressing bending of the take-up shaft. It is mentioned.

As described above, the present invention can be preferably applied to a shutter curtain for a large opening because, as the width of the shutter curtain becomes larger, it is necessary to simplify the structure and secure the necessary functions of the shutter curtain. The greater the width of the shutter curtain, the greater the weight, and the more difficult it is to handle during transportation, construction, or manufacturing.Thus, the present invention has facilitated handling. This is because there is a high need to go.

Further, among the shutter devices with the door mechanism described above, one having the following configuration can be cited as one of the most suitable configuration examples for the present invention. That is, in the above-described invention, the covering portion and the overlapping margin portion of the curtain body that overlaps at least the covering portion are all formed of sheet-like members, and the shutter curtain has an inner dimension exceeding 12 m in the curtain width direction. And a shutter curtain for a large opening that partitions a space having a large cross-sectional width.

Further, in the above, the structure of the communicating portion in the shutter device with the door mechanism of the present invention may be an opening shape or a slit shape as described above, but it is particularly preferable to be as follows. That is, in the above-described invention, the communication portion is formed in an opening shape having a two-dimensional spread, and is a side of a fixed width arranged along the closing direction distal end near the closing direction distal end of the shutter curtain. It is preferable to have

Here, the front end of the shutter curtain in the closing direction refers to, for example, a portion provided with a seat plate, a weight and the like. Also, "opening with a two-dimensional spread"
The term "having a side having a constant width" is intended to exclude a slit-shaped object, and the term "having a side having a constant width" is intended to exclude a shape such as an inverted triangle or a circle having no side along the front end in the closing direction. Therefore,
Shapes include a square, a rectangle, a triangle (the bottom is along the tip in the closing direction), a trapezoid, an M-block cross section, an inverted home base, a semicircle (the upper half of a circle), and the like.

In the case of such a configuration, since the communicating portion has an opening shape, it can pass through the communicating portion more easily than in the case of the slit shape. For this reason, for example, in the case of a disaster prevention shutter device, evacuation is smoothly performed.
