Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof structure of athletics facilities such as baseball and soccer or other large-scale facilities, and in particular, an openable and closable roof which can be opened and closed depending on the weather. Membrane roof structure.

[0002]

2. Description of the Related Art Recently, for indoor athletics facilities, etc.,
Large fixed dome roofs have been adopted. As a structural type of the fixed dome type roof, there are known a steel truss structure including a single-layer truss and a multi-layer truss, a cable structure, and a structure in which the steel truss structure and the cable structure are combined. In such a fixed dome type roof, there is a roof having a membrane structure in which a roof finishing material made of a metal plate or the like is attached to the steel frame truss, or a membrane swelled by air filling is pressed by a cable structure.

By the way, the fixed dome roof has a closed atmosphere even if it has a membrane structure. For this reason, in recent years, an openable membrane roof structure has been developed. As this open / close type membrane roof structure, for example, the structure described in JP-A-63-280166 is known.

As shown in FIGS. 15 and 16, guide rails 2 are provided on both sides of a lower structure B in parallel with each other, and a plurality of units are successively arranged on the guide rail 2. Both ends in the longitudinal direction of the roof frame A are movably mounted, and the lower ends of the connecting rods 5 are pivotally supported between the lower ends of both ends of the unit roof frame A that are adjacent to each other. The upper end of 5 is pivotally attached, and a valley cable 7 is stretched between the opposing pivot joints between the two connections, and between the valley cable 7 and the upper end of the adjacent unit roof frame A. The V-shaped film material 8 is stretched.

In the openable membrane roof structure having the above-mentioned structure, when the unit roof frame frames A are sequentially moved along the guide rails 2 toward the central portion of the rails 2, the unit roof frame frames A adjacent to each other in the longitudinal direction. The connecting rods 5 and 5, which are folded up in a standing state between the lower portions of the end portions, expand as the space between the preceding unit roof frame frame A and the following unit roof frame frame A increases, and The pivotally-attached portion 6 of both the connecting rods 5 and 5 descends.

Along with this, the upper end portions of the unit roof frame frames A adjacent to each other and the pivotally connecting portions 6, 6 of the connecting rods 5, 5 are joined.
The V-shaped membrane material 8 stretched between the valley cable 7 stretched between 6 is tensioned, and the membrane material 8 is expanded between the unit roof frame frames.

[0007]

However, the openable membrane roof structure having the above structure has the following problems to be solved. That is, (1) First, since the structure is such that the film material is folded,
Short service life due to the inability to use A-type film materials (A-type film materials that have a long service life but are unsuitable for folding) formed of glass fiber or the like that have a long service life. ,
There is no choice but to use B and C film materials. (2) Since the valley cable is used to stretch the membrane material, the membrane material and the valley cable rub against each other when the membrane material is tensioned, and the membrane material and the valley cable are worn, resulting in a service life. I have a problem.

(3) While the unit roof frame frames are sequentially moved, the folded membrane material is unfolded, and when all the unit roof frame frames move on the guide rails and are located at predetermined positions. Since tension is applied to the entire membrane material, if the unit roof frame frame, the connecting rod, or the like malfunctions even at one place, it cannot be opened or closed at that time. (4) Until the roof is completely closed, tension is not applied to the membrane material and it is in a flapping state, so it will become unstable if it is fanned by the wind, etc., and smooth opening and closing operations will be performed. Is not possible, and even when the membrane material is folded,
Since the film material is exposed to the outside, it is easily agitated by wind and the like, and there is a problem of accumulation of rainwater and dust.

(5) Since the tension is introduced into the entire membrane material by the valley cable only after the roof is completely closed, there are two types of opening and closing of the roof: a fully open state and a fully closed state. Only the choice can be made, and the opening area of the roof cannot be adjusted. (6) A large amount of power is required because it is necessary to deploy the membrane material whose central portion is folded downwards upward.

The present invention has been made in view of the above circumstances, and has a long service life of the membrane material, smooth opening and closing, is stable against wind turbulence, and can adjust the opening area of the roof. Another object of the present invention is to provide an openable membrane roof structure capable of opening and closing the roof with a small amount of power and a method for opening and closing the roof.

[0011]

In order to achieve the above object, the opening / closing type membrane roof structure according to claim 1 of the present invention has arch-shaped guide rails arranged parallel to each other, and the guide rails.

In the above, a top roof unit having substantially the same shape as the roof unit and higher rigidity than the roof unit is connected to the top of the plurality of roof units of the open / close roof, and the top roof unit is connected to the guide rail. It is provided with a drive carriage for traveling along.

The opening / closing type membrane roof structure of claim 3 is the same as that of claim 2
In the above, the leading roof unit has an opening / closing structure similar to that of the roof unit.

The opening / closing type membrane roof structure according to claim 4 is the structure according to claim 1.
In any one of 3 to 3, the open / close roof including the plurality of roof units is arranged on both sides of the central portion in the longitudinal direction of the guide rail.

The openable membrane roof structure according to claim 5 is the structure according to claim 4.
In the above, a roof storage portion for supporting and storing the closed roof in a closed state is provided at both ends of the guide rail.

The openable membrane roof structure according to claim 6 is the structure according to claim 5.
In the above, the folding means for sequentially bending the connecting members of the frame frames of the respective roof units moving to the roof storage portion side is provided in front of the roof storage portion.

The roof opening / closing method of the opening / closing type membrane roof structure according to claim 7 is the roof opening / closing method of the opening / closing type membrane roof structure according to claim 6, wherein each of the opening / closing roofs provided on both sides of the guide rail. When opening the openable roof from the closed roof state in which the top roof units are connected at the central portion of the guide rail, after releasing the connection between the top roof units, projecting the folding means from the guide rail. Thus, after slightly bending the connecting material of the roof unit located in front of the roof storage section, the drive carriage is moved to the roof storage section side by a predetermined pitch, thereby further bending the connecting material to the roof. The process of folding the open / close frame of the unit and moving it to the roof storage part to store it is repeated sequentially, while it is stored in the roof storage part provided at both ends of the guide rail. When closing the open / closed roof, the leading roof unit of each opening / closing roof is moved by a predetermined pitch to the central portion side of the guide rail by the drive carriage, and then the leading roof unit is further moved by a predetermined pitch.

The feature is that they are connected at the center of the guide rail.

[0018]

In the openable membrane roof structure according to claim 1 of the present invention, the roof is opened and closed by running a plurality of roof units along the guide rails. Since the film material is stretched independently on a pair of openable and closable frames, the film material does not bend when each roof unit travels on the guide rail or when the open / close frame is opened and closed. , Is always stretched flat.

Therefore, it is possible to use a type A film material formed of glass fiber or the like having a long service life, and the film material itself does not bend and it is not necessary to use a valley cable. The service life of the material is significantly longer than before.

Further, since each roof unit has an independent structure in which a film material is stretched on itself, even if the opening / closing frame of a roof unit cannot be opened / closed due to some reason, other roof units cannot be opened or closed. The unit is functioning normally, so it can be opened or closed at that point. Furthermore, since each roof unit has the membrane material stretched on itself, the membrane material is not in a fluttered state, and the open / close frame on which the membrane material is stretched is stable by stretching the connecting material. Since it is a triangular truss, it is always structurally stable when each roof unit travels on the guide rail. Therefore,
Even when the roof is opened and closed, it can be opened and closed smoothly even if the wind blows it. Also, when each roof unit travels on the guide rail, it will always be in a structurally stable state,
It is structurally stable even if the roof unit is stopped midway along the guide rail. Therefore, the opening area of the roof can be easily adjusted by stopping the roof unit in the middle of the guide rail.

In addition, since the film material is stretched in advance on the open / close frame, no force is required to bend the film material itself,
Therefore, it is possible to open and close the roof with the power required only to move the roof unit on the guide rails.

In the openable membrane roof structure according to claim 2,
Since the leading roof unit which sequentially drives a plurality of roof units on the guide rail has substantially the same shape as the roof unit and has higher rigidity than the roof unit, by driving the leading roof unit by the drive carriage,
The roof unit can be stably driven along the guide rail.

In the openable membrane roof structure according to claim 3,
Since the top roof unit has the same opening / closing structure as the roof unit, the top roof unit can also be folded when the roof is opened by folding each roof unit toward the end of the guide rail to open the roof. The folded roof can be made more compact.

In the opening / closing type membrane roof structure according to claim 4,
Since the opening / closing roof composed of the plurality of roof units is arranged on both sides of the central portion in the longitudinal direction of the guide rail, the opening / closing operation of the roof can be performed simultaneously from both end portions of the guide rail, thus shortening the opening / closing time. . Further, since the outer part can be covered by the openable roof and the central part can be opened, the roof can be opened and closed according to various events, sports and sports.

In the openable membrane roof structure according to claim 5,
Since both ends of the guide rail are provided with a roof storage part that supports and stores the open / closed roof in a folded state, the film material is not exposed to the outside when the roof is open, and thus the film material is not exposed. It will not be agitated by the wind and will not accumulate rainwater or dust. Further, since the roof storage portion is provided at the end of the arch-shaped guide rail, the folded open / close roof can be reliably supported from the back side, and the collapse of the open / close roof can be prevented. You can

In the openable membrane roof structure according to claim 6,
When the roof is opened, the connecting members of the frame frames of the roof units that move along the guide rail to the roof storage section side are sequentially bent by the bending means, and further bent by the movement of each roof unit. By sequentially folding the roof units that have been opened, all the roof units are folded and sequentially stored in the roof storage unit, so that the open / close roof can be stored easily.

In the roof opening / closing method of the opening / closing type membrane roof structure according to claim 7, when opening the opening / closing roof, after disconnecting the leading roof units from each other, the folding means is projected from the guide rail. Thus, after slightly bending the connecting material of the roof unit located in front of the roof storage section, the drive carriage is moved to the roof storage section side by a predetermined pitch, thereby further bending the connecting material to the roof. The steps of folding the open / close frame of the unit and moving it to the roof storage unit for storage are sequentially repeated.

On the other hand, when the opening / closing roof is closed, the leading roof unit of the opening / closing roof is moved to the central portion side of the guide rail by a predetermined pitch by the driving carriage, and then the leading roof unit is further moved by a predetermined pitch. The steps of pulling out the roof unit from the roof storage unit, opening the open / close frame and extending the connecting member to support the open / close frame in the open state are repeated in sequence, and finally, the roof units at the top of each open / close roof are connected to each other. Are connected at the center of the guide rail.

Further, as shown in FIGS. 1 and 2, the opening / closing roof 1 is provided at both ends of the guide rails 10, 10.
Roof storage parts 33, 33 for supporting and storing the folded parts 2, 12 are provided supported by the keel arches 13, 13. The roof storage portion 33 is a box-shaped member extending between the guide rails 10, 10 and has a front surface serving as a storage opening 33 a for storing the open / close roof 12.
The wall surface 33b facing a supports the openable roof 12 in a folded state from the back side, thereby preventing the openable roof 12 from collapsing.

Further, in front of the roof storage section 33,
As shown in FIG. 14, folding means 35 is provided.
The folding means 35 is adapted to sequentially bend the hinge 23 of the connecting member 17 of the frame frame 14 of each roof unit 11 which moves toward the roof storage portion 33 side by protruding and retracting from the guide rail 10. .

In the folding means 35, when the roof unit 11 moves to the roof storage portion 33 side when the roof is opened, and the connecting member 17 is located above the folding means 35. Then, projecting from the guide rail 10 and connecting material 1

By sequentially repeating the step of being buried inside and waiting until the next roof unit 11 moves, the connecting member 17 of each roof unit 11 is sequentially bent. ing.

Next, a method of opening and closing the roof by the openable membrane roof structure having the above configuration will be described. (1) When opening the openable roofs 12, 12, in this case, as shown in FIG. 10, the leading roof units 26, 26 of the openable roofs 12, 12 provided on both sides of the guide rail 10 are the guide rails. The open / close roofs 12 and 12 are connected at the central portion of 10 and are opened from the closed state.

First, after disconnecting the connection between the top roof units 26, 26, the bending means 35 is projected from the guide rail 10. Then, the connecting member 17 of the roof unit 11 located at the upper side of the folding means 35, that is, the joint member 17 of the rearmost roof unit 11, is slightly bent from the hinge 23 at the center thereof. After the connecting member 17 is bent, the bending means 35 is buried in the guide rail 10 and stands by. Next, the front roof unit 26 is moved by the drive carriage 28 toward the roof storage portion 33 side by a predetermined pitch (a length substantially equal to that of the connecting member 17 in the extended state). Then, the rearmost roof unit 11 is pushed toward the roof storage portion 33 side, whereby the opening / closing frames 16 and 16 are folded while the connecting member 17 of the roof unit 11 is further bent, and It is stored in the portion 33 from the storage opening 33a.

When the rearmost roof unit 11 is folded and stored in the roof storage portion 33, the next roof unit 11 connected to the rearmost roof unit 11 is located above the folding means 35. Located in this roof unit 11
The tie member 11 of the roof unit 11 is further folded by slightly bending the tie member 11 by the bending means 35 and then moving the leading roof unit 26 toward the roof storage portion 33 side by a predetermined pitch. While being bent, the open / close frames 16 and 16 are folded and stored in the roof storage portion 33 through the storage opening 33a. Then, as shown in FIGS. 11 and 12, the above steps are performed on the roof unit 11 ...
All roof units 11 which are successively connected to the top roof unit 26 by repeating the above steps sequentially.
Is folded and stored in the roof storage portion 33. The top roof unit 26 is stored in the roof storage portion 33 as it is.

(2) When closing the open / close roofs 12 and 12, first, the open / close roofs 12 housed in the respective roof housing units 33.
The leading roof unit 26 is moved by a predetermined pitch to the center side of the guide rail 10 by the drive carriage 28. Then
One side of the open / close frames 16 and 16 of the next roof unit 11 in the state of being folded by the top roof unit 26 is pulled, whereby the bent connecting member 17 extends straight and is structurally stable. One roof unit 11 having a triangular cross section is formed. It should be noted that, when the connecting member 17 is straightly extended from the bent state, it is locked in a straight state so that it can bear compression and tension forces.

Next, by further moving the top roof unit 26 by a predetermined pitch, the next roof unit 11 is pulled out from the roof storage portion 33 in the same manner as described above, and the roof unit 11 having a triangular cross-sectional view. By sequentially repeating the steps of forming
As shown in FIG. 3, each roof unit 11 of the open / close roof 12 that has been folded and stored in the roof storage portion 33 is pulled out while forming a triangular shape in cross section. Finally, the opening / closing roofs 12, 12 are completely closed by connecting the leading roof units 26, 26 of the respective opening / closing roofs 12, 12 at the central portion of the guide rail 10.

As described above, in the open / close type membrane roof structure of this embodiment, the pair of open / close frames 16 and 16 of the frame frame 14 constituting each roof unit 11 are openable / closable.
Since the film materials 15 and 15 are stretched independently of each other, the film material 1 can be used when each roof unit 11 travels on the guide rail 10 and when the open / close frames 16 and 16 are opened and closed.
No. 5 is not bent and is always stretched flat. Therefore, it is possible to use the film material 15 of type A formed of glass fiber or the like having a long service life,
In addition, since the membrane material itself does not bend and it is not necessary to use the valley cable as in the conventional case, the useful life of the membrane material becomes significantly longer than that of the conventional case.

Further, since each roof unit 11 has an independent structure in which the film material 15 is stretched on itself, the open / close frames 16, 16 of a certain roof unit 11 cannot be opened / closed for some reason. However, since the other roof units 11 function normally, opening / closing at that time does not become impossible. Further, since each roof unit 11 has the membrane material 15 stretched on itself, the membrane material 15 is not fluttered in any state of opening and closing the roof, and the membrane material 15 is stretched. The open / close frames 16 and 16 are connecting members 17.
By extending, it becomes a stable triangular truss,
When each roof unit 11 travels on the guide rail 10, it is always in a structurally stable state. Therefore, it is possible to smoothly open and close the roof even when the roof is opened and closed by wind or the like.

Each roof unit 11 has a guide rail 1
Since the vehicle is always in a structurally stable state when traveling on 0, it is structurally stable even if the roof unit 11 is stopped in the middle of the guide rail 10. Therefore, the roof unit 11 can be stopped in the middle of the guide rail 10,
This allows the opening area of the roof to be easily adjusted.

In addition, the film material 15 is composed of the open / close frames 16 and 1.
Since it is stretched in advance in FIG. 6, it does not require a force to bend the film material 15 itself, so that the power for moving the roof unit 11 on the guide rails, that is, the drive carriage 28 provided in the leading roof unit 26 is not required. The roof can be opened and closed only by the driving force.

Further, since the leading roof unit 26, which sequentially moves the roof units 11 ... On the guide rail 10, has substantially the same shape as that of the roof units 11 and has a rigid structure, the leading roof unit 26 is driven by a drive carriage. By traveling by 28, the roof units 11 ... Can be stably traveling along the guide rails 10, and the roof can be opened and closed more smoothly.

Further, since the open / close roofs 12 and 12 are arranged on both sides of the central portion of the guide rail 10 in the longitudinal direction, the opening / closing operation of the roof can be performed simultaneously from both ends of the guide rail 10. Therefore, it is possible to shorten the opening and closing time, and by opening and closing the roof starting from the central part of the roof, it is possible to cover the outer part and open the central part. It can be opened and closed.

Further, since the roof storage portions 33 are provided at both ends of the guide rail, the membrane material 1 is provided when the roof is open.
5 is not exposed to the outside, and thus the film material 15
Will not be agitated by wind, and rainwater or dust will not accumulate. Further, since the roof storage portion 33 is provided at the end of the arch-shaped guide rail 10, the folded open / close roof 12 can be reliably supported from the back side, and the open / close roof 12 collapses. Can be prevented.

Further, when the roof is opened, the roof storage 3
The folding member 35 slightly bends the connecting member 17 of each roof unit 11 which moves along the guide rail to the 3 side,
Furthermore, by moving each roof unit 11, the roof unit 1
Since 1 is sequentially folded, all roof units 11 ... Can be easily folded and stored in the roof storage portion 33.

Although the top roof unit 26 has higher rigidity than the roof unit in the above embodiment, the top roof unit 26 may have the same opening / closing structure as the roof unit 11. In this case, when the roof units 11 are brought close to the ends of the guide rails 10 to fold and open the roof, the top roof unit can also be folded, so that the folded open / close roof can be made more compact. You can Further, in the above embodiment, the guide rail 1
Two opening / closing roofs 12 and 12 are arranged with the central portion in the longitudinal direction of 0 and 10 as boundaries, and the opening and closing roofs 12 and 12 can be opened and closed on both sides from the central portion of the opening 2.
In the present invention, only one opening / closing roof may be provided on the guide rail 10 and the opening 2 may be opened / closed from one side of the opening 2 toward the other side.

As described above, according to the first aspect of the present invention.
According to the opening / closing type membrane roof structure, since the membrane material is stretched independently on the pair of opening / closing frames of the frame frames constituting each roof unit, each roof unit travels on the guide rail. At the time of opening or closing the opening / closing frame, the film material is not bent and is always stretched flat. Therefore, it is possible to use a type A film material formed of glass fiber or the like having a long service life, and the film material itself does not bend and it is not necessary to use a valley cable. There is no wear with the material. Therefore, the useful life of the membrane material is significantly longer than that of the conventional one, and the roof has excellent durability.

Further, since each roof unit has an independent structure in which the membrane material is stretched on itself, even if the opening / closing frame of a roof unit cannot be opened / closed for some reason, the other roof units cannot be opened or closed. The unit is functioning normally, so it can be opened or closed at that point. Furthermore, since each roof unit has the membrane material stretched on itself, the membrane material is not in a fluttered state, and the open / close frame on which the membrane material is stretched is stable by stretching the connecting material. It becomes a triangular truss. Therefore, when each roof unit travels on the guide rail, it is in a structurally stable state at all times, so that the roof unit can be smoothly opened and closed even when the roof is opened and closed due to wind or the like. Further, when each roof unit travels on the guide rail, the roof unit is always in a structurally stable state, so that it is structurally stable even if the roof unit is stopped in the middle of the guide rail. Therefore, the roof unit can be stopped in the middle of the guide rail, so that the opening area of the roof can be easily adjusted.

In addition, since the film material is stretched in advance on the open / close frame, there is no need to bend the film material itself,
Therefore, it is possible to open and close the roof with the power required only to move the roof unit on the guide rails.

According to the opening / closing type membrane roof structure of the present invention, since the leading roof unit for successively moving the roof units on the guide rail has substantially the same shape as the roof unit and has higher rigidity than the roof unit, By driving the front roof unit by the drive carriage, the roof unit can be stably moved along the guide rails, and the opening and closing of the roof becomes smoother.

According to the opening / closing type membrane roof structure of claim 3, since the leading roof unit has the same opening / closing structure as the roof unit, each roof unit is folded while being brought close to the end of the guide rail to open the roof. In doing so, the top roof unit can also be folded, so that the openable roof in the folded state can be made more compact.

According to the opening / closing type membrane roof structure of claim 4, since the opening / closing roof composed of the plurality of roof units is arranged on both sides of the central portion in the longitudinal direction of the guide rail, the opening / closing operation of the roof is performed by the guide rail. Can be done from both ends at the same time,
Therefore, the opening / closing time can be shortened. Also, since the roof can be opened and closed starting from the central part of the roof, the outer part can be covered and the central part can be opened. Therefore, the roof can be opened and closed according to various events, athletic competitions. You can

According to the opening and closing type membrane roof structure of the present invention, since the roof storage portions for supporting and storing the folded roof in the folded state are provided at both ends of the guide rail, The film material is not exposed to the outside. Therefore, the stored membrane material is agitated by wind, etc.
Since rainwater, dust, etc. do not accumulate, the durability of the film material can be further improved. Further, since the roof storage portion is provided at the end of the arch-shaped guide rail, the folded open / close roof can be reliably supported from the back side, and the collapse of the open / close roof can be prevented. You can

According to the openable membrane roof structure of claim 6, when the roof is opened, the connecting member of each roof unit moving along the guide rail toward the roof storage part is slightly bent by the bending means. Moreover, since the roof units are sequentially folded by moving each roof unit, all the roof units can be easily folded and stored in the roof storage portion.

According to the roof opening / closing method of the opening / closing type membrane roof structure of claim 7, when the opening / closing roof is opened, the folding means is projected from the guide rail after disconnecting the leading roof units from each other. After slightly bending the tie member of the roof unit located in front of the roof storage unit, the drive unit is moved to the roof storage unit side by a predetermined pitch to further bend the tie member and the roof unit. The steps of folding the open / close frame and moving it to the roof storage part are sequentially repeated. On the other hand, when closing the open / close roof, the top roof unit of the open / close roof is driven by the drive carriage to a predetermined pitch on the center side of the guide rail. Opening and closing of the roof unit that comes out of the roof storage section by moving it and then moving the top roof unit further by a predetermined pitch. The process of sequentially opening the ram and extending the connecting member to support the open / close frame in an open state is repeated, and finally, the top roof units of each open / close roof are connected at the center of the guide rail. Therefore, opening and closing of the roof, roof storage, etc. can be performed stably and smoothly.
