Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-shaped roof spreading device that opens or closes a specific portion of a large span of a large roof.

BACKGROUND OF THE INVENTION AND PRIOR ART: Various types of exhibition halls, gymnasiums, and other buildings with wide floors often use a ramen structure, an arch structure, a truss structure, or a combination thereof. In these structures with large roofs, it is often the case that the roof is a rigid structure and itself is a strength member, such as a dome-shaped roof.

Further, in these structures, there are many examples of so-called open / close roofs in which the main part of the roof is movable according to the purpose of use.

In the conventional open / close roof, in order to make a part of the roof structure as described above movable, a method of moving a roof part corresponding to a required open / close area in almost the current state is adopted. That is, the moving part of the roof is moved as it is, while being divided into several parts, or while being bent and folded. The sliding guide mechanism of the open / close roof has a structure such as a plug-type roof in order to have a water blocking function as well.

Problems to be solved: In such a movable opening / closing roof, the mechanical strength of the moving part must be sufficient, so that the weight becomes large and the driving power for moving needs to be large-scale. . As the water storage at the boundary between the parts forming the openable roof or the boundary between the openable roof and the fixed roof becomes a complicated mechanism, an increase in the burden of maintenance work has been unavoidable.

On the other hand, it has been proposed to form the open / close roof with a lightweight and soft material, and it has been put to practical use in a narrow portion such as an arcade division area. However, the large roof described above is lightweight and
If a soft material is applied, sufficient measures are required due to the difficulty in handling the roofing material during expansion and storage, and the lack of the function to apply an appropriate tension during expansion to ensure a stable tension. It was rare.

The present invention has been made to solve the above problems, and is an extension used when a lightweight and flexible sheet-like roof is used as an opening / closing roof for opening / closing a required portion of a large roof. The purpose is to provide the device. And, even though it is a lightweight and soft sheet-like roof, it is possible to obtain a stable stretched state in which wrinkles, slack, fluttering and the like do not occur.

Means for Solving the Problems: In order to achieve the above object, a sheet-shaped roof spreading apparatus according to the present invention includes guide rails mounted on opposite sides of a pair of arch beams included in a structure of a building. In a light and soft sheet-shaped roof spreading device that is supported by, and is opened and closed by a deployment and storage mechanism, a guide follower fixed to both ends of the opening / closing bar is fitted to the guide rail, and a tension bar is attached to the opening / closing bar. It is fixed integrally, and one end of the tension bolt is screwed and inserted into a predetermined position of the tension bar so that the relative position to the tension bar can be adjusted, and a tension plate is welded to the other end of the tension bolt. Furthermore, by fixing the tip of the sheet roof to the tension plate, the moving end of the sheet roof is fixed. And, in the deployed rail is 沿設 integrally with the guide rail,
The sheet-like roof is evenly supported in a state in which the extending slides attached to the both edges of the sheet-like roof at an appropriate pitch are inserted and fitted in the extending rail, and the guide follower is provided with an advancing / retreating mechanism of the guide follower. It is characterized by being attached via a wire.

Action of the Invention: The opening and closing of the sheet-like roof is performed by a program operation, for example, using a deployment and storage mechanism installed at the base of a beam along which guide rails and extension rails are installed. After the sheet-shaped roof is extended, the head of the tension bolt is rotated to adjust the length of the tension bolt and the tension plate is moved, whereby fine wrinkles remaining on the sheet-shaped roof can be eliminated.

In the present invention, the storage mechanism is provided with a take-up roll, and both ends of the take-up roll are made thin by providing a step, and the take-up roll driving machine is used as a torque motor during or after expansion. It is possible to apply back tension to the sheet-shaped roof, and by doing so, it is possible to easily store the expansion sliding device, and to eliminate the large wrinkles that occur on the sheet-shaped roof with a simple operation. It is possible to smoothly deploy and store the sheet roof.

Embodiment: An embodiment of the present invention will be described below with reference to the drawings. First to
FIG. 3 illustrates a case where the spreading device (1) according to the present invention is applied to a building (2), and a pair of arch beams (4).
The guide rails (6) and the extension rails (7) are installed as one body on the side surfaces facing each other. The sheet-like roof (5) is provided by being guided and supported by the guide rail (6) and the extension rail (7) which are integrally provided. The expansion device (1) is provided between the storage mechanism (20) installed at one end of the arch beam (4) and the expansion mechanism (23) installed at the other end of the arch beam (4) and pulled by the expansion mechanism (23). The roof is then closed, and the roof is wound around the storage mechanism (20) to open.

4 to 6 show the tip of the sheet-like roof (5) on the side of the expansion mechanism (23) and the main parts of the integrated guide rail (6) and expansion rail (7). A downward-facing flange (7) 'and an upward-facing flange (7) "facing each other at an appropriate interval on the inner surface of the arch beam (4) installed in parallel at an interval equal to the width of the roof opening / closing part set in advance. And a plate-shaped guide rail (6) projecting inward above the extension rail (7) and having a wheel (7) rolling on the upper surface of the extension rail (7). 9) ′ (preferably made of phenol resin, etc.)
The guide followers (9) having the above are arranged between the extension rail (7) and the guide rail (6) on each side, and the opening / closing bar (8) is provided between the guide followers (9) (9) which are symmetrical to each other. Fix by tension.

A tension plate (12) is attached to the tip of the sheet-like roof (5), which exerts a traction force for extension evenly on the sheet-like roof (5). This tension plate (12)
Is a sheet-like roof (5), which has a plurality of sheets of appropriate length arranged side by side rather than a single sheet over the entire width of the sheet roof (5).
Connecting the tension plates (12) and (12) with a plate joiner (12) 'is more effective in equalizing the tension, and is useful for smoothly tensioning the sheet roof.

Then, the tension bar (13) is fixed to the lower surface of the opening / closing bar (8) having the guide followers (9) and (9) on both sides, and the tension bar (1) is attached via the tension bolt (11).
Connect 3) and the sheet roof (5). Further, the extension slides (10) are arranged at appropriate pitch intervals on both side edges of the sheet roof (5), and the extension slides (10) are inserted into the extension rails (7). To do. As shown in FIG. 4 or 5, the spreading slide (10) is composed of an upper piece and a lower piece, and each side edge of the sheet-like roof (5) is bent. It can be clamped from the top and bottom and tightened with bolts and nuts. In this embodiment, the core wire is inserted into the bent portion of the sheet-shaped roof to increase the fastening force, and the material of the spreading slide (10) is made of nylon having high slidability, and the downward flange of the spreading rail (7) ( 7) ′ and the upward flange (7) ″.
The sheet-like roof (5) has a plurality of extension slides (10) (10) arranged on both side edges of the sheet-like roof, and the extension rails (7) face each other.
By (7), it is supported while maintaining a tension balanced with its own weight, and it is possible to smoothly open and close while sliding smoothly.

The embodiment illustrated in FIGS. 1 to 3 is the case where the advancing / retreating mechanism of the guide follower (9) is of a traction type. In this embodiment, the winch included in the expansion mechanism (23) winds and pulls the wire (24) connected to the guide follower (9), and the winches on both sides are synchronously wound by the encoder control or the like. Perform each guide follower (9)
The sheet-shaped roof (5) can be extended by moving evenly, or it can retreat.

The storage mechanism (20) for winding the sheet-like roof (5) is composed of a winding roll (21) and a driving machine (22) for the winding roll (21). The drive machine (22) uses a torque motor to rotate the take-up roll (21) when the sheet-shaped roof (5) is rewound and stored, and also to expand the sheet-shaped roof (5) by the spreading mechanism (23). Even when the tip is pulled and stretched, a rotational torque in the rewinding direction is generated, and the sheet roof (5) can be subjected to back tension. When the sheet-shaped roof (5) has been stretched along the arch beam (4) for the required span (equal to the length of the stretching rail (7)), the stretching mechanism (23) is stopped. By applying a rewinding torque that is several times the back tension during spreading from the drive machine (22) that uses a torque motor to the take-up roll (21) while applying the brake, Sheet roof without deformation (5)
Can be held with sufficient tension. In this case, in order for the sheet-shaped roof (5) to be accurately fed out under a predetermined balanced tension, the sheet-shaped roof (5) needs to be regularly wound around the winding roll (21) while avoiding irregular winding. is there.
Therefore, it is preferable that the take-up roll (21) is not a flat roll but a medium-high expander roll. In particular, the winding roll (21) used in the present invention
In order to absorb the bulkiness of the spreading slides (10) arranged in large numbers on both edges of the sheet-like roof (5), steps are provided to narrow both ends.

Furthermore, a sheet-like roof (5) is provided immediately in front of the storage mechanism (20).
By attaching a sweeper such as a wiper or a rotary brush (both well-known ones can be used, illustrations are omitted) for rubbing against the surface, dust adhered to the building due to environment / weather or adhered to the building Etc. can be cleaned,
It also has the effect of increasing the durability of the sheet-like roof (5) and maintaining the visibility when using a transparent sheet material.

As another embodiment, the advancing / retreating mechanism of the guide follower (9) that moves along the guide rail (6) may be a self-propelled type. In this embodiment, a guide prime mover (9) is mounted with a driving prime mover, and a rack pinion for transmitting the drive prime mover is attached (one of the wheels (9) 'may be a rack pinion). ) It is possible to move forward and backward at a required speed without slipping by meshing with a rack gear or a rack pin provided on the upper surface. Then, a plurality of proximity sensors are arranged in series on the guide rails (6) on both sides to detect the advance / retreat of each guide follower (9) to control the rotary drive of the tower mounted prime mover, and to guide the guide followers ( 9) and (9) are reliably synchronized. Therefore, if the guide followers (9) and (9) are moved forward synchronously, the sheet-shaped roof is smoothly extended, and when the sheet-shaped roof is opened, the sheet-shaped roof is retracted at a speed corresponding to the winding speed of the storage mechanism. Alternatively, the sheet-shaped roof member can be wound up on the winding roll in an orderly manner by being driven without power.

In the present embodiment, the follow nut is projected from the guide follower, and the slide screw to be screwed into the follow nut is installed along the guide rail.
Then, when the slide screw is rotated, the guide follower is advanced through the fastener that is screwed into the slide screw, and the sheet roof connected to the guide follower is extended. This embodiment has a relatively short span and the shape of the open / close roof is suitable for a flat roof or a one-way roof.

Through each of the above-mentioned examples, the degree of progress of the guide followers on both sides is determined by, for example, attaching a torsion sensor to the opening / closing bar between the guide followers on both sides to confirm the deviation of movement, in addition to the degree described in each example. May be. Various measures can be applied to maintain the synchronous consistency of the advancing / retreating mechanisms of both guide followers.

EFFECTS OF THE INVENTION As described above, according to the present invention, one end of the tension bolt is screwed and inserted into a predetermined position of the tension bar, and the tension plate is welded to the other end of the tension bolt. , Furthermore, since the tip of the sheet-shaped roof is fixed to this tension plate, after expanding the sheet-shaped roof, by rotating the head of the tension bolt to adjust the length of the tension bolt,
The tension plate can be moved, thereby eliminating the fine lines that remain on the sheet roof after spreading.

Further, if both ends of the winding roll of the storage mechanism are formed to be thin by steps, it is possible to easily store the spreading sliding members that are attached to both end edges of the sheet-shaped roof at an appropriate pitch. By applying back tension to the sheet-shaped roof during or after the expansion by driving with, it is possible to smoothly deploy and store the sheet-shaped roof without the need for a simple operation to eliminate large wrinkles generated in the sheet-shaped roof.
