[0001]
BACKGROUND 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, as a shutter device for disaster prevention for fire prevention, smoke prevention, etc. It can be suitably used as a large opening shutter device for partitioning.
[0002]
[Background]
In general, a shutter device for various purposes is provided at a doorway or a passageway of a building to provide a shutter device for various purposes for moving a shutter curtain up and down to partition a space. Is one of them.
[0003]
Conventionally, as a shutter device for disaster prevention, a device provided with a metal (iron) shutter curtain has been used. And the shutter device for disaster prevention equipped with a metal shutter curtain has a width of width because there is a Ministry of Construction notification based on Article 112, Paragraph 14, Item 4 of the Building Standards Law Enforcement Ordinance (Showa 48 Notification No. 2564) The standard specification was 5 m or less. Therefore, in the case of a so-called large opening with a large opening in the building where the shutter device for disaster prevention should be installed (the cross-sectional width of the space to be partitioned by the shutter curtain), a guide rail is usually provided in the middle of the opening. By setting up a pillar, a standard disaster prevention shutter device with a width of 5 m or less was provided in series.
[0004]
In addition, the shutter device for disaster prevention is left behind in the disaster prevention area after the shutter curtain is lowered in order to ensure the evacuation route for people in the building in the event of an emergency such as a fire. It is necessary to provide an emergency doorway in order to secure escape routes for those who have been affected.
[0005]
Conventionally, in a disaster prevention shutter device provided with a metal shutter curtain, it is relatively difficult to provide such an emergency doorway in the shutter curtain itself. Often, a side door for emergency use was provided on the side.
[0006]
On the other hand, in recent years, development of various materials has progressed, and cloth screens with excellent fire resistance, heat shielding properties, smoke shielding properties, waterproof properties, etc. have been developed, and disaster prevention equipped with shutter curtains formed by such cloth screens. Shutter devices have been used with the approval of the Minister of Construction under Article 38 of the Building Standards Act.
[0007]
Since such cloth screens can be sewn and can be easily sealed, an emergency doorway can be easily provided in the shutter curtain itself. Disaster prevention shutter devices have been used in which emergency shutters are provided in the shutter curtain itself.
[0008]
[Problems to be solved by the invention]
However, when providing an emergency doorway in the shutter curtain itself, the following various considerations should be taken, including not only the case of a shutter curtain formed by a cloth screen but also the case of a metal shutter curtain. There is a problem.
[0009]
That is, first, the emergency doorway is provided for securing the evacuation route, so the emergency doorway is arranged for the disaster prevention shutter device so that its original function can be fully exhibited. It is desirable to make the arrangement according to the situation of the building (for example, the arrangement situation of walls, handrails, escalators, elevators, etc.) in the vicinity of the opening to provide. In other words, it is desirable to arrange according to behavioral characteristics (moving characteristics) when an evacuee evacuates.
[0010]
Next, in order to facilitate the evacuation of evacuees, as described above, the installation position of the emergency entrance and exit is determined according to the situation of the building or the behavior characteristics of the evacuees resulting therefrom. However, it can be said that it is convenient and desirable for evacuation to have more emergency doorways provided in the shutter curtain for the evacuees. However, providing an unlimited number of emergency exits and entrances on the shutter curtains makes it difficult to ensure airtightness, which may reduce smoke shielding performance, is unfavorable in terms of strength, and takes time and effort for manufacturing. As a result, the manufacturing cost increases. Therefore, it is necessary to provide an emergency doorway at a desired position for the evacuees while avoiding these disadvantages from the manufacturing viewpoint.
[0011]
The above-mentioned problems related to the layout of the emergency entrance / exit are more conspicuous as the opening where the shutter device is to be installed becomes larger, that is, as the shutter curtain becomes wider. Closely related to the problem of dealing with Further, not only the shutter device for disaster prevention but also a shutter device having other purposes, the same problem occurs when an entrance / exit is provided in the shutter curtain itself.
[0012]
In addition, there are various large and small spaces in the building, and accordingly, the width of the opening in which the disaster prevention shutter device is to be installed varies in size. Accordingly, when installing the disaster prevention shutter device, it is necessary to deal with a large opening, but in that case, there are the following problems.
[0013]
In other words, a disaster prevention shutter device having a metal shutter curtain as described above, and preparing a plurality of standard specifications with a width of 5 m or less and connecting them in correspondence with a large opening, a guide rail is provided. In addition, since the middle pillar must be set at an intermediate position of the opening, there are problems in that there are many restrictions on the architectural design, such as an obstacle to forming a large space, and the appearance is not preferable.
[0014]
On the other hand, if the Minister of Construction approves under Article 38 of the Building Standards Act, even a shutter device for disaster prevention equipped with a metal shutter curtain with a width exceeding 5 m can be used. It may be possible to accommodate a large opening by installing one wide disaster prevention shutter device.
[0015]
However, in the case of a metal shutter curtain, increasing the width increases the weight, making handling difficult during transportation, construction, or manufacturing, especially for shutter curtains with a width that exceeds standard specifications. , It is remarkable.
[0016]
The problem of dealing with the large opening as described above is not limited to the shutter device for disaster prevention, but also occurs in the case where a space having a large cross-sectional width must be partitioned even in the case of a shutter device having other purposes. It is a problem.
[0017]
A main object of the present invention is to provide a shutter device with a door mechanism that can realize the arrangement of the door mechanism on the shutter curtain according to the situation of the building and is convenient and convenient for those who intend to use the door mechanism provided on the shutter curtain. Is to provide.
[0018]
Further, an additional object of the present invention is to appropriately achieve one or more of the following: facilitating production, reducing production cost, facilitating handling during transportation and construction, and dealing with large openings. There is a place to provide a shutter device with a door mechanism.
[0019]
[Means for Solving the Problems]
The present invention relates to a shutter curtain having a curtain body that partitions a space, a communication portion that communicates the space between the front and back of the curtain partitioned by the curtain body, and a cover portion that covers the communication portion and forms a door mechanism together with the communication portion. In the shutter device with a door mechanism, the door mechanism is arranged in the vicinity of the guiding means for guiding the movement of the moving body. That is, the door mechanism is characterized in that it is arranged at a position where the extension line in the moving direction of the moving body guided by the guiding means and the shutter curtain intersect or in the vicinity thereof.
[0020]
Here, in terms of structure, the communication portion has an opening having various shapes such as a square, a rectangle, a triangle, a trapezoid, an M block cross-sectional shape, an inverted home base shape, a circle, an ellipse, and a semicircle. Or a slit-shaped one. In terms of applications, emergency entrances used for emergency evacuation, such as when a fire breaks out, can be cited as the main ones. Entrance / exit used for pets such as dogs and cats, or just a sight window that does not presume the entrance / exit of people or objects (for example, a shutter device for disaster prevention) In this case, it is also included for checking smoke generation status and fire progress status through the shutter curtain). Note that the term “entrance / exit” in the present application includes not only the case where entry / exit and passage from both directions are possible, but also the case where entry / exit and passage only in one direction are possible.
[0021]
Further, the cover portion may be formed of a member separate from the curtain body (for example, in the case of FIG. 1 described later), or may be integrally formed of the same member as the curtain body (for example, described later). In the case of FIG. 10). When the cover is formed of a separate member as in the former, the cover is attached to the curtain body by, for example, fastening, welding with a fastening tool such as sewing, bonding, rivet, bolt / nut, screw, etc. Any combination such as fasteners, buttons, and Velcro can be used, and it can be detachable or sliding doors that can be slid up and down, left and right, etc. The attachment method according to the installation purpose of the shutter device, such as whether or not it is necessary to ensure the material or the airtightness may be used. In addition, it is good also as a structure which can attach a key and can prevent a cover part from opening also in the case where it forms in another member like the former, and the case where it forms integrally like the latter. Moreover, you may attach | subject the mark, character, etc. which display the presence of a communication part (For example, in the case of the shutter device for disaster prevention, the presence of an emergency entrance) on the surface of a cover part.
[0022]
Furthermore, when the door mechanism is focused on only one side of the curtain front and back, the most basic structure is composed of one communication part and one cover part (for example, FIG. 1 described later). However, the present invention is not limited to this, and one door mechanism may be configured by a plurality of communication portions and one cover portion (for example, in the case of FIG. 6 described later). One communication mechanism and a plurality of cover portions may constitute a single door mechanism (for example, in the case of FIGS. 7 and 8 to be described later), and a plurality of communication portions and a plurality of cover portions make one door mechanism. One door mechanism may be configured (for example, in the case of FIG. 9 described later). In addition, when one door mechanism is comprised by the several cover part among said each pattern, the whole communication part is made into the whole or substantially whole (however, the shutter device for disaster prevention) combining several cover parts In this case, it is preferable that the whole is completely covered.) It is sufficient that each of the covering portions covers the whole or almost the whole of the communication portion. There is no need to be. Therefore, when paying attention to one cover part, it is only necessary to cover at least a part of the communication part (see FIGS. 7, 8, and 9 described later).
[0023]
And in comprising one door mechanism, a cover part may be provided only in the one side of the front and back of a shutter curtain, and may be provided in both sides (for example, in the case of FIG. 2 mentioned later), Alternatively, it may be provided so as to enter the communicating portion (for example, in the case of FIGS. 7 and 8 described later).
[0024]
Furthermore, the overlap margin part of the cover part and the curtain body may or may not be provided, but in the case of a disaster prevention shutter device, from the viewpoint of ensuring airtightness, It is desirable to provide an overlap portion.
[0025]
In addition, a moving object mainly means a person, but also includes pets such as dogs and cats, vehicles such as forklifts and trucks, and objects such as products and products sent on a conveyor line such as a belt conveyor. (For example, in the case of FIG. 13 described later). In the case of the shutter device for disaster prevention, it means mainly rescuers such as evacuees and fire fighters who extinguish fires.
[0026]
Further, the guiding means includes a walking aid such as a wall and a handrail, a large number of continuous protrusions provided on the floor surface for visually impaired persons or the like, a laying sheet formed with these protrusions, an elevator doorway, an escalator A boarding / alighting part of an upper end or a lower end, upper and lower ends of stairs, a conveyance line such as a belt conveyor, and the like are included. In addition, tactile guidance means (means that can add physical restriction to the movement of the moving body) that allows the moving body to contact directly or indirectly and guides the movement of the moving body tactilely in this way. In addition to this, there are also other visual guidance means for visually guiding the movement of the moving body, such as guide lights, guidance display boards, entrance / exit display boards, etc. provided on the ceiling, floor, wall, etc. . In addition, auditory guidance means for audibly inducing movement of the moving body, such as an alarm buzzer and a speaker, are included, and if the moving body is excellent in olfactory sense, such as a dog, Also included are olfactory guidance means for inducing movement of Further, a combination of these means may be used.
[0027]
When a plurality of door mechanisms are arranged, it is sufficient that at least one door mechanism is arranged in the vicinity of the guiding means, and it is not necessary that all the door mechanisms are arranged in the vicinity of the guiding means. However, it is preferable that the majority (more preferably all) of the door mechanisms are arranged in the vicinity of the guiding means or in an end section described later.
[0028]
In the present invention, since the door mechanism is arranged in the vicinity of the guiding means for guiding the movement of the moving body, the arrangement of the door mechanism according to the building situation, that is, the arrangement state of the guiding means in the building is realized. The For this reason, in the case of the moving characteristic of the moving body based on the guidance of the guiding means, for example, in the case of the shutter device for disaster prevention, the arrangement according to the behavior characteristic at the time of evacuation of the refugee is realized, and the evacuation of the refugee is smooth The above-mentioned purpose is achieved by these.
[0029]
The present invention also includes a curtain body that partitions the space, a communication portion that communicates the space between the front and back of the curtain partitioned by the curtain body, and a cover portion that covers the communication portion and forms a door mechanism together with the communication portion. In a shutter device with a door mechanism provided with a shutter curtain, N is an integer of 2 or more, and includes end positions on both sides of the inner width of the shutter curtain in the curtain width direction perpendicular to the moving direction of the shutter curtain, And when the portion occupying a dimension width of 1 / N of the total width in the curtain width direction from the position of each inner width end to the center position in the curtain width direction is defined as the end section, At least one of the end sections is provided with at least one door mechanism.
[0030]
Here, each meaning of the communication portion, the cover portion, and the door mechanism is the same as in the case of the invention in which the door mechanism is disposed in the vicinity of the guiding means described above.
[0031]
The “moving direction of the shutter curtain” means an opening / closing direction when the shutter curtain performs an opening / closing operation (or a closing direction when only the closing operation is performed). It is arbitrary such as horizontal direction. However, when the shutter device for disaster prevention is used, it is preferable to set the direction so that the weight can be lowered.
[0032]
The “curtain width direction orthogonal to the moving direction of the shutter curtain” means a direction orthogonal to the moving direction of the shutter curtain in the plane along the shutter curtain, and the thickness direction (thickness direction) of the shutter curtain. Does not mean.
[0033]
Furthermore, the “internal full width dimension in the curtain width direction” means that the full width dimension in the curtain width direction of the shutter curtain is swallowed by a guide means (for example, a guide rail or a groove formed directly on a wall or column). The width dimension of the part excluding the part, that is, the width dimension of the part exposed to the outside (the part seen from the space partitioned by the shutter curtain).
[0034]
“At least one door mechanism is arranged in at least one of the end sections” means that the entire one door mechanism is contained in the end section. If only a part of the door mechanism is in the end section, it is excluded. Therefore, the case of N = 2 means that there is at least one door mechanism that is not arranged across the center position in the curtain width direction. In addition, as long as one door mechanism is entirely contained in the end section, there may be another door mechanism in which only a part is included in the end section, or completely from the end section. There may be other door mechanisms in the detached position.
[0035]
Further, since it is “at least one of the end sections”, the door mechanism is not necessarily disposed in the end sections on both sides, and may be disposed only in one end section (for example, described later). In the case of FIG. 4). However, it is preferable to arrange | position in the edge part division of both sides.
[0036]
In the present invention, since at least one door mechanism is disposed in at least one of the end sections on both sides, the guide means such as a guide rail that guides the shutter curtain is usually located at the inner width end position. Since the wall for providing the door is disposed, the door mechanism can be disposed in consideration of the wall layout. For this reason, the arrangement of the door mechanism corresponding to the situation of the building, that is, the arrangement situation of the wall in the building is realized. For example, in the case of the shutter device for disaster prevention, it is expected that the evacuation is performed while moving along the wall. Arrangement according to the behavioral characteristics (movement characteristics) at the time of evacuation of the evacuees is realized, and the evacuation of the evacuees can be performed smoothly, thereby achieving the object.
[0037]
In the invention in which the door mechanism is arranged in the end section described above, at least one door mechanism may be arranged in the vicinity of the guiding means for guiding the movement of the moving body.
[0038]
As described above, when the door mechanisms are arranged in the vicinity of both the end section and the guiding means, the arrangement of the door mechanisms according to the situation of the building is further enhanced.
[0039]
Furthermore, in the above-described invention in which the door mechanism is arranged in the end section, N is preferably an integer of 3 or more.
[0040]
Thus, when N at the time of defining the end section is an integer of 3 or more, the width dimension between the end sections on both sides is equal to or larger than the width dimension of the end section. An intermediate section will be formed. Therefore, if the door mechanism is not arranged in the intermediate section, it is possible to secure a door mechanism non-installation section in the intermediate section.
[0041]
For this reason, in addition to realizing the arrangement of the door mechanism in accordance with the building situation, that is, the arrangement of the walls in the building, securing the door mechanism non-installation section prevents the shutter curtain strength from being lowered, It is possible to reduce labor, reduce manufacturing costs, and avoid inconvenience in manufacturing shutter curtains. Moreover, in the case of the shutter device for disaster prevention, it becomes easy to ensure airtightness, and it is possible to prevent a decrease in smoke shielding performance. In other words, in the case of a shutter device for disaster prevention, we want to avoid the demands of evacuees or rescuers who want to be able to evacuate smoothly (hereinafter sometimes simply referred to as evacuees) and inconveniences in manufacturing. It is possible to satisfy both the requirements of the shutter curtain manufacturer, contractor, owner, etc. (hereinafter sometimes simply referred to as the manufacturer).
[0042]
In the invention in which the door mechanism is disposed in the end section described above, the inner width end position of the shutter curtain and the end on the inner width end position side of the door mechanism disposed in the end section. It is desirable that the interval is not more than the width dimension of the door mechanism.
[0043]
Thus, when the door mechanism in the end section is arranged, the arrangement of the door mechanism according to the situation of the building, that is, the arrangement situation of the wall in the building becomes even more effective.
[0044]
The present invention also includes a curtain body that partitions the space, a communication portion that communicates the space between the front and back of the curtain partitioned by the curtain body, and a cover portion that covers the communication portion and forms a door mechanism together with the communication portion. In a shutter device with a door mechanism provided with a shutter curtain, N is an integer of 2 or more, and includes end positions on both sides of the inner width of the shutter curtain in the curtain width direction perpendicular to the moving direction of the shutter curtain, And, when the portion occupying 1 / N of the width of the inner width in the curtain width direction toward the center position in the curtain width direction from each inner width end position is determined as the end section, the door The mechanism is arranged only in the end curtain of the shutter curtain or in the vicinity of the guiding means for guiding the movement of the moving body, and not in other parts. The one in which the features.
[0045]
As described above, when the door mechanism is not arranged in a portion other than “in each end section or in the vicinity of the guiding means”, that is, not in each end section and in the vicinity of the guiding means. The door mechanism is disposed only at a position necessary for a person who intends to use the door mechanism provided on the shutter curtain, and the door mechanism is not disposed at a position that is not so necessary.
[0046]
For this reason, in addition to the realization of the layout of the door mechanism according to the situation of the building, that is, the arrangement of the walls in the building or the arrangement of the guiding means, the door mechanism is not arranged in other parts. It is possible to avoid disposing the door mechanism at a position where necessity is not high. Accordingly, it is possible to prevent a reduction in the strength of the shutter curtain, reduce manufacturing effort, reduce manufacturing costs, and avoid inconvenience in manufacturing the shutter curtain. Moreover, in the case of the shutter device for disaster prevention, it becomes easy to ensure airtightness, and it is possible to prevent a decrease in smoke shielding performance. In other words, in the case of the shutter device for disaster prevention, it is possible to satisfy both the evacuee's request for smooth evacuation and the shutter curtain manufacturer's request for avoiding manufacturing inconvenience. It becomes like this.
[0047]
In the above, the installation purpose of the shutter device with a door mechanism of the present invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section) is arbitrary. However, the main purpose is a shutter device for disaster prevention for the purpose of fire prevention and smoke prevention, but it is not limited to this, and it is necessary to form a special space such as a dark room, a clean room, a cold storage, and a greenhouse. The shutter device may be a shutter device for solar radiation shielding, a shutter device for crime prevention, or the like. In short, any shutter device in which it is useful to provide a door mechanism on the shutter curtain may be used.
[0048]
Furthermore, the installation place of the shutter device with a door mechanism according to the present invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section) is arbitrary. Like ordinary general houses, buildings, garages, factories, warehouses, coolers, etc., various shutters for entrances and exits, shutters for windows, shutters installed in the middle of the passageway or at the boundary between the passageway and the hall The shutter device may be provided in various buildings, or may be a shutter device provided in various structures such as an underground shopping center, a station premises, a tunnel, and a ship.
[0049]
Further, the structure of the shutter device with a door mechanism of the present invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section) includes the door mechanism on the shutter curtain. It is optional as long as it can be provided. Therefore, the present invention can be applied to various types of shutter devices as follows. For example, the shutter curtain may be formed using a sheet-like member, and the shutter curtain may be wound around a winding shaft, or may be folded and stored in a storage unit, and the shutter curtain may include a large number of slats. The shutter device may be a type of shutter device that is formed by connecting the shutter curtains so that the shutter curtain is wound around the winding shaft of the storage portion and stored. In addition, 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 section, or the individual panels are folded and stored in a connected state. Further, a shutter device of a type that is wound and stored may be used. Furthermore, a shutter device in which the shutter curtain is formed by a plurality of pipe members connected to each other by a link member may be used, or an overhead type shutter device for feeding and storing may be used. Further, for example, a shutter device of a type provided with a shutter curtain formed by combining various shutter curtains, such as a shutter curtain formed partly with slats and the remaining part with sheet-like members. But you can. In addition, the materials of the components and components of the various shutter curtains described above are arbitrary, and as long as they are sheet-like members, for example, cloth screens, soft resin sheets such as vinyl chloride and urethane, and rubber Alternatively, a sheet formed of a rubber-like substance can be used. For example, a metal, a synthetic resin, ceramics, wood, or the like can be used as long as it is a slat, a panel, a link member, a pipe member, or the like.
[0050]
Furthermore, as described above, the material of the shutter curtain constituent parts and constituent members is arbitrary, but the following is particularly preferable. That is, in the above-described invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section), the cover portion overlaps at least the cover portion of the curtain body. It is preferable to form the overlap margin part by a sheet-like member.
[0051]
Here, the sheet-like member may be of any kind as long as it is flexible, such as a cloth screen, vinyl sheet, urethane sheet, rubber sheet, etc., but it is used for fire prevention and smoke prevention purposes. In this case, for example, silica cloth or glass cloth, or those obtained by spraying, applying or impregnating a fireproof paint or a waterproof coating material as a fireproof coating material can be preferably used. Further, the sheet-like member may be combined with a reinforcing metal such as a wire mesh or a resin wire, and if such reinforcement is performed, not only when used for disaster prevention but also for normal use. Even in this case, the sheet is hardly damaged, and the durability of the sheet can be improved, which is effective.
[0052]
The present invention can be suitably applied to a shutter curtain formed to include a sheet-like member as described above. A sheet-like member such as a cloth screen is lighter than a metal shutter curtain and is also folded. This is because it is possible to facilitate handling during transportation, construction, or manufacturing. For this reason, the shutter curtain formed including the sheet-like member is suitable for a wide shutter curtain, and the advantage increases as the horizontal width of the curtain increases. In addition, since it is a sheet-like member, sewing and the like are possible, and it is suitable for providing a door mechanism in terms of structure compared to a metal shutter curtain, and airtightness is also ensured compared to a metal shutter curtain. Easy. Therefore, the shutter curtain formed including the sheet-like member is optimal for constituting a disaster prevention shutter device corresponding to a large opening.
[0053]
In addition, the sheet-like member forming the series of shutter curtains may be a single sheet, or a plurality of sheets may be joined by sewing, bonding, welding, or the like. It may be divided into a plurality of division types, and may be combined with a fastener or the like at the time of shutter curtain closing operation or simply overlapped to form a series of shutter curtains.
[0054]
Further, as described above, the installation purpose of the shutter device with a door mechanism of the present invention is arbitrary, but it is particularly preferable to do as follows. That is, in the above-described invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section), the shutter curtain has a disaster prevention function, and the communication portion is very It is preferable that it is an entrance / exit.
[0055]
Here, the disaster prevention function means that at least one kind of performance can be exhibited among various performances such as fireproof performance, fireproof performance, smokeproof performance, smoke insulation performance, heat insulation performance, waterproof performance, and wind pressure performance. .
[0056]
Thus, the present invention can be suitably applied to the shutter device for disaster prevention, because the shutter device for disaster prevention is originally required to be provided with an emergency doorway for securing an evacuation route for evacuees. This is because the effect of the present invention relating to the arrangement of the door mechanism is sufficiently exhibited.
[0057]
Furthermore, in the above description, the internal dimensions in the width direction of the shutter curtain in the shutter device with a door mechanism of the present invention are arbitrary, but the following is particularly preferable. That is, in the above-described invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section), the shutter curtain is a standard internal method in the curtain width direction. It is preferable that the shutter curtain for a large opening has an internal dimension larger than the dimension and partitions a space having a large cross-sectional width.
[0058]
Here, the shutter curtain for large openings refers to one that satisfies at least one of the following conditions.
[0059]
As the first condition, it exceeds the width based on "Ministry of Construction Notification (Article No. 2564 of 1968) based on Article 112, Paragraph 14, Item 4 of the Building Standards Law Enforcement Ordinance". It is a thing exceeding 5 m (a thing larger than the standard specification of so-called iron fire and smoke / shutter).
[0060]
The second condition is that it exceeds the width based on the “Ministry of Construction Notification (Article No. 2564 of 1968) based on Article 112, Paragraph 14, Item 4 of the Building Standards Law Enforcement Ordinance”. It is mentioned that it is more than 8m (larger than the iron shutter provided near the Otsukaze fire door).
[0061]
The third condition is that the vehicle (cargo is loaded) specified by a Cabinet Order based on Article 47, Paragraph 1 of the Road Law (Vehicle Restriction Order Article 3, Paragraph 1, Item 4, Decree 375 of the final revision in 1993) In this case, the maximum length in that state) is exceeded, that is, the total width dimension in the curtain width direction exceeds 12 m.
[0062]
The fourth condition is a semi-trailer linked vehicle that runs on a high-speed motor vehicle national road specified by a government ordinance based on Article 47, Paragraph 1 of the Road Law (Decree 3 of the Vehicle Restriction Ordinance, Decree 375 of the final revision in 1993) or A full trailer-connected vehicle whose cargo does not protrude forward or rearward of the towed vehicle body, but exceeds the maximum length, that is, the total width dimension in the curtain width direction is 16.5 m (for semi-trailer connected vehicles) It is mentioned that it exceeds 18 m (when loaded on a full trailer coupled vehicle).
[0063]
The fifth condition is that the inner width in the curtain width direction is about 3 times or more, preferably about 6 times or more the width of the door mechanism. Here, the reference value of about three times is obtained when one door mechanism is provided at each inner end of the shutter curtain and a door mechanism non-installation portion having a dimension width comparable to these is secured between them. This is based on being able to be regarded as a large aperture shutter curtain. In addition, the standard value of about 6 times is provided with one door mechanism at an interval corresponding to the width dimension of the door mechanism from both ends of the shutter curtain, and the same dimension width (door) between them. It is a numerical value obtained when a door mechanism non-installation part having a width dimension of two mechanisms) is secured, and if it exceeds this value, it can be regarded as a shutter curtain for large openings It is.

It is mentioned that it is what is divided | segmented into. In addition, after manufacturing in the divided state and transporting it to the building site in the divided state, it is connected at the building site and made into one shaft, manufactured in the divided state, connected at the factory, and one After being transported to the construction site as a single shaft, 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 and made into a single shaft, manufactured in a divided state, transported to the building site in a divided state, and then connected and used in a divided state at the building site (In this case, the axis positions of the axes may be aligned or may be shifted in parallel. In this case, the shutter curtain is also of a split type, and the shutter is in a split state when the shutter curtain is closed. Ten is the concatenated or simply superposed with it Taking the configuration and the like are connected.), Etc. In such fasteners, also include any ones.
[0065]
As a seventh condition, when the shutter device with a door mechanism of the present invention is a retractable shutter device that retracts and stores a shutter curtain on a retractable shaft, an intermediate position in the axial direction of the retractable shaft The support shaft such as an auxiliary roller that supports the winding shaft and the shutter curtain wound on the winding shaft and suppresses the bending of the winding shaft is provided at least at one place. It is done.
[0066]
As described above, the present invention can be suitably applied to the shutter curtain for a large opening. As the width of the shutter curtain increases, the arrangement of the door mechanism corresponding to the situation of the building is realized and the door mechanism is used. This is because there is a high demand for realization of a convenient shutter device that is convenient for the user, and the larger the shutter curtain width, the greater the weight, making it difficult to handle during transportation, construction, or manufacturing. Therefore, it is highly necessary to facilitate handling according to the present invention.
[0067]
Among the shutter devices with a door mechanism described above, an example of the optimum configuration for the present invention includes the following configuration. That is, in the above-described invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section), the cover portion overlaps at least the cover portion of the curtain body. The overlapping part is formed of a sheet-like member, and the shutter curtain is a shutter curtain for large openings having an internal dimension exceeding 12 m in the curtain width direction and partitioning a space having a large cross-sectional width. Can be mentioned.
[0068]
Furthermore, as described above, the structure of the communicating portion in the shutter device with a door mechanism of the present invention may be an opening shape or a slit shape as described above, but the following is particularly preferable. That is, in the above-described invention (including both the invention in which the door mechanism is arranged in the vicinity of the guiding means and the invention in which the door mechanism is arranged in the end section), the communication portion has an opening shape having a two-dimensional extension. It is preferable to have a side with a constant width that is formed and disposed along the front end portion in the closing direction in the vicinity of the front end portion in the closing direction of the shutter curtain.
[0069]
Here, the front end portion of the shutter curtain in the closing direction refers to a portion provided with, for example, a seat plate or a weight. In addition, the “opening shape having a two-dimensional extension” is intended to exclude a slit-shaped object, and “having a side with a constant width” means an inverted triangle having no side along the front end in the closing direction, The purpose is to exclude a shape such as a circle. Accordingly, shapes such as a square, a rectangle, a triangle (with the base along the front end in the closing direction), a trapezoid, an M block cross-sectional shape, an inverted home base shape, and a semicircular shape (a circular upper half) are included.
[0070]
In the case of such a configuration, since the communication portion has an opening shape, the communication portion can be easily passed as compared to the slit shape. For this reason, for example, in the case of a disaster prevention shutter device, evacuation is smoothly performed.
[0071]
