2. Description of the Related Art Conventionally, super-large dome buildings have been used for all-weather baseball, soccer, rugby, and other athletic competitions, and also for multipurpose and efficient use at events such as exhibition halls and concert venues. It is customary to build on the premise. When used in athletic competitions such as baseball, of course, a partition wall is not necessary, and it is rather an obstacle, but when partitioning the inside of a building, a partition with a wall curtain film is conveniently adopted.

In this case, the wall curtain film is installed in a partition pattern according to the purpose of use. For example, in the case of a concert venue, it is hung sufficiently high on the floor so that the sound insulation and the light shielding effect are sufficiently enhanced together with the recess forming the stage. When used in an exhibition space, the wall curtain film is simply hung so low that it does not impair the effect of partitioning it from its neighbors. For this reason, the ceiling part of the dome building is equipped with equipment such as a winch, a pulley device, and a baton for lifting and lowering the wall curtain film from the ceiling as described above, and a sub baton for hanging is prepared at the upper end of the wall curtain film.

A very large one with a width dimension of about 10 m is used.

[0005]

As described above, since the large wall curtain membrane having a long length and a large width is bulky at the time of storage and is inconvenient to handle, its construction, removal, storage and storage work can be carried out quickly and conveniently. In order to carry out efficiently, it is desirable to develop and use properly devised winding and erection methods, as well as erection facilities and equipment.

[0006] In particular, a large wall curtain film containing glass fibers needs to be careful because if it is carelessly bent sharply beyond a certain radius of curvature during storage and storage, wrinkles will occur and it will be unsightly. In addition, it is required that the folded state of the wall curtain film be as compact as possible, and at the time of construction, lightness that can be worked mechanically smoothly. It is desired that the heavy and bulky wall curtain film be mechanically and conveniently stored and stored in a warehouse or the like, and can be pulled out and used whenever necessary.

Therefore, an object of the present invention is to install or remove a long, wide and heavy large wall curtain film containing glass fibers by a method suitable for its properties, or to remove it to a warehouse or the like in a state convenient for reuse. (EN) It is an object to provide a winding and setting method for storing and storing, and a winding device as a setting facility used for the above method.

[0011]

Embodiments and Examples of the Invention The method and apparatus for winding a large wall curtain film according to the present invention are preferably implemented mainly for enabling multipurpose use of the internal space of a large dome building. It For example, when a wall curtain film is installed in the building 1 in a partition pattern as shown in FIG. 1 when viewed in plan, when viewed in elevation, the pulley device 3 is installed on the dome ceiling 2 as shown in FIG. A system is adopted in which the baton 5 is installed and supported horizontally by the wire 4 suspended from the pulley device 3, and the wall curtain film M is suspended through the baton 5.

More specifically, as shown in FIG. 3, two wires 4 and 4 are unwound from one common winch 6 fixedly installed on the ground floor 14 on the ground, and each of them is wound on the ceiling of the building. After separately wrapping around the pulley devices 3 and 3,
One wire 4 is fixed to the left end of the baton 5, and the other wire 4 is branched at its tip into a Y-shape and fixed to the right end of the baton 5 and two points in the middle. One baton 5 is hung horizontally at three points (or four points are also available). Further, the anti-sway wire 7 of the baton 5 is also stretched in an inverted triangular shape, and an anti-sway weight 8 is attached to this.

The structural details of the baton 5 and the sub baton 10 are shown in FIGS. 4 and 5. The baton 5 has a box truss structure having an inverted triangular cross section, and a suspension ring 5a is provided downward on a lower chord member 5'of the box truss structure. Wall curtain film M

The upper end of the film is sandwiched between the angle 9 provided with a and the flat steel 11, and the two are sewn together by a plurality of bolts 12. The upper and lower suspension rings 5a and 9a are detachably connected to each other by an eggplant 13.

The lower part of the large wall curtain film M containing glass fibers suspended on the ceiling of the building as described above is wound into the winding device 20. A winding device 20 shown as an embodiment will be described below with reference to FIG. As shown in FIG. 6 and FIG. 7 as a whole of the winding device 20, the winding shaft 21 for winding the wall curtain film M having a large widthwise dimension is located at both ends of the winding shaft 21 and is larger than the widthwise dimension of the film. It is rotatably supported by a pair of bearing blocks 22 that are vertically divided at positions with a slightly wide interval. Bearing block 2
Reference numeral 2 is a sliding bearing in which a circular arc groove is formed in a nylon block. The winding shaft 21 is made of a steel pipe having a large radius of curvature that does not damage the glass fibers of the wall curtain film M. The support frame 23 provided with the left and right bearing blocks 22 and 22 is configured to be elongated in the axial direction of the winding shaft 21 with the minimum necessary width. Specifically, a grooved steel or the like is used to form the shape viewed in the direction of FIG. 6 into a concave shape, and the fork of the forklift is freely inserted and removed between the lower part of the gantry and the floor 14 in the direction of FIG. The gap H is provided.

The supporting stand 23 of the above-mentioned structure of the winding device 20.
First, a positioning pin 26 is prepared as a means for freely positioning and fixing it on the floor 14 of the building in an arrangement along the partition pattern as shown in FIG. 1 (FIG. 6). Support stand 23
Provide vertical sockets 27 on the bases 23a at both ends of
The positioning pin 26 is passed vertically downward into the socket 27. On the other hand, on the floor 14 of the building, a pin hole 28 for positioning is provided in advance at the position of the support frame determined by the partition pattern, and the positioning pin 26 passed through the socket 27 as described above is on the floor 14. Positioning is performed by entering the pin hole 28. The base 23a
A bracket 29 is attached outward to the bracket 29, and a vertically downward adjuster bolt 30 is prepared for the bracket 29. A thrust pad 39 is attached to the tip of the adjuster bolt 30. When the floor 14 has a horizontal error, the leveler of the support base 23 is leveled by raising and lowering the adjuster bolt 30, and at the same time, the positioning and fixing action is achieved (see FIG. 8).

FIG. 9 shows the structure of the winding shaft 21 described above, particularly the structural details of the portion supported by the bearing block 22.
In short, the range of the winding shaft 21 around which the wall curtain film M is wound is formed by using an existing steel pipe, and is supported by the bearing block 22. Therefore, both ends 21 having a length of about 160 mm, which require precision machining. ′ Is a separate body, and both have flanges 31 and 32 welded to their respective pipe ends and are integrally joined with bolts 33, thereby facilitating precision cutting of the bearing portion. A round handle 34 is attached to the outer circumference of one flange 32.
The round handle 34 is formed to have an effective outer diameter of about 350 mm so as to be suitable for manually rotating the winding shaft 21 in the case of fine adjustment of the film or failure. Round handle 3
4 is conveniently used when a tension of an appropriate amount is applied to the installed wall curtain film M by hand, or when a correction operation is performed when the winding state of the film deviates in the left-right direction. The round handle 34 is also conveniently used for transporting the winding device 20 by several people and adjusting the installation position.

A pair of half-moon shaped members 36, 36 are symmetrically formed in order to form a square hole 35 for receiving the rotational force of the electric motor, particularly at the drive-side end of the short end portions indicated by the reference numeral 21 '. Work is also done to fix the arrangement (Fig. 9, Fig. 1
1). As can be seen in FIGS. 8 and 9, the bearing block 22
The support of the take-up shaft 21 by means of is configured so as to be rotatable and at the same time movable about 25 mm to the left and right in the axial direction. Based on this fact, the axial direction adjusting means of the winding shaft 21 is configured as shown in FIG. The end plate 40 is fixed inside the tube end opening on the non-driving side of the winding shaft 21, and the adjusting bolts 41 that are located on the center line of the winding shaft 21 and penetrate the end plate 40 are provided on both sides of the end plate 40. It is installed by fastening with a nut 43 via thrust bearings 42, 42 arranged on the surface. Therefore, even if the winding shaft 21 rotates,
The adjusting bolt 41 can maintain a non-rotational stationary state, and the winding shaft 21 and the adjusting bolt 41 are in a relationship of integrally moving in the axial direction. The nut 43 is fixed by a stop pin 44. The adjusting bolt 41 is projected outward from the tube end of the winding shaft 21 and has a notch-shaped bolt hole 45a of a fixed frame 45 which is protruded by fixing both ends to the support frame 23 as shown in FIG. Penetrates through. The adjusting bolt 41 is formed in a rectangular rod shape with both side surfaces symmetrically cut. The stopper ring 47 provided at the tip of the wing nut 46 screwed into the adjustment bolt 41 is positioned on the left side of the fixed frame 45, and is sandwiched between the stopper plate 47 attached to the inside of the fixed frame 45. There is. The notch-shaped bolt hole 48a provided in the restraint frame 48 is formed in a rectangular hole shape having a parallel surface with a width dimension in which the flat corner portion 41a of the adjusting bolt 41 is fitted, and completely prevents rotation of the adjusting bolt 41. It is configured. Therefore, when the wing nut 46 is rotated in the forward and reverse directions, the wing nut 46, which is sandwiched between the fixed frame 45 and the restraint frame 48 and is prevented from moving in the axial direction, and the adjustment bolt 41 are screwed, and as a result, the adjustment bolt is moved. 41, and thus the winding shaft 21 is moved in the axial direction.

The above-mentioned axial adjustment means is used as follows. When the lower part of the wall curtain film whose upper end is hung by the baton is stored in the winding shaft 21 of the winding device 20 so as to be retractable, if the vertical arrangement of the baton and the winding device is deviated, the wall curtain is displaced. When the film is wound, the film is twisted, and wrinkles are formed on the wound part of the film, which is unsightly. Further, the end portion of the film wound around the winding shaft is displaced to the left and right, resulting in an irregular winding state. As a countermeasure when such a problem occurs, the wing nut 46 is rotated to move the winding shaft 21 properly in the axial direction, thereby eliminating the twist of the wall curtain film.
Wrinkles can be eliminated and misalignment of the ends of the wound film can be eliminated relatively easily. During such adjustment work, it is convenient to turn the above-mentioned round handle 34 by hand, rather than rotating the winding shaft 21 by an electric motor.

Next, the motor base 24 is attached to one side of the support base 23.
An electric motor 25 with a speed reducer is removably mounted on the motor base 24 as a rotary machine that rotationally drives the winding shaft 21. As shown in FIGS. 11 and 12, the details of the structure are fixed on the upper surface of the motor base 24 in parallel to the axial direction of the winding shaft 21 and the guide rails 40, 40 which are horizontally opposed to each other. On the other hand, a motor base 42 formed of a steel plate having a width and a thickness that fits exactly in the inward horizontal U-shaped guide grooves 41, 41 formed by the guide rails 40, 40 has a front half portion of the electric motor 25. It is attached to the bottom bottom part. A drive angle shaft 43 is attached to the rotation shaft of the electric motor 25. The drive angular shaft 43 is fitted into a square hole 35 formed by fixing a pair of half-moon shaped members 36 in a symmetrical arrangement inside the tube end on the drive side of the winding shaft 21 described above, so that the rotational force can be transmitted. When viewed in the front direction as shown in FIG. 12, the shape is square, and when viewed in the side direction as shown in FIG. 11, the tip side is formed in a pyramidal shape with a length of about 1/3. .

Therefore, by aligning the motor base 42 of the electric motor 25 with the left and right guide grooves 41, 41 and pushing it in the axial direction toward the tube end of the winding shaft 21, and abutting it on the dead end 44 at the deep end of the groove, Both the purpose of mounting the electric motor 25 and the work of fitting the drive angular shaft 43 into the angular hole 35 of the winding shaft 21 can be achieved easily at the same time. As a means for preventing the motor base 42 from slipping out, the motor base 2
A stopper mechanism 45 is provided at the front end of 4. 13, the handle lever 46 is rotatably attached by a shaft bolt 47 to a substantially central portion on the outer surface side of the connecting member 24a at the tip portion of the motor base 24, as shown in FIG. The shaft bolt 47 is arranged in parallel with the axis of the winding shaft 21, and the operating surface 46a of the handle lever 46 has the shaft bolt 4
7 and a large-diameter circle portion 46b that protrudes higher than the upper surface of the motor base 24 and, conversely, is lower than the upper surface of the motor base, while forming a surface perpendicular to 7 The small-diameter circular portion 46c is formed separately. That is, as described above, when the electric motor 25 is mounted on the motor base 24, the handle lever 46 is manually turned clockwise as viewed in the direction of FIG. By protruding the motor base 42, it is possible to reliably fix the mounting state of the electric motor 25. Conversely, when viewed in the direction of FIG. 13B, the handle lever 46
Is rotated counterclockwise so that the small-diameter circle portion 46c is located above, the motor base 42 can be pulled out. Then, when the electric motor 25 is pulled out, the relationship between the drive angular shaft 43 and the angular hole 35 of the winding shaft 21 is also canceled.

As described above, the electric motor 25, which is detachable from the motor base 24, is not a component peculiar to the winding device 20 arranged in a line along the partition pattern as shown in FIG. As a reusable equipment to be installed according to the above, a substantial reduction in the actual manufacturing price of one winding device can be achieved. The structural form of the electric motor is not limited to the illustrated example, and for example, the drive angular shaft 43 may be attached to the rotary shaft protruding from the reduction mechanism.

In any case, the large wall curtain film M containing glass fiber is basically wound up by the winding device 20,
The winding device together with the winding device is loaded onto a transporting trolley using a forklift or the like, and the transporting trolley loaded with the plurality of winding devices 20 is moved by a towing vehicle to be transported and stored in a predetermined storage location such as a warehouse. When using the wall curtain membrane, pull out the transport carriage from the storage location and drive it to the use location, and arrange the winding devices 20 with a forklift or the like on the floor at the use location along a partition pattern as shown in FIG. The positioning pin 26 is inserted into the pin hole 28 of the floor 14 to fix and position it. After that, the sub-baton 10 at the upper end of the wall curtain film is connected to a substantially horizontal baton 5 suspended from the ceiling of the building by a wire 4, and the wire 4 is wound up to vertically move the wall curtain film M to a predetermined height. Suspend under an appropriate tension. At this time, the tension of the wall curtain film is sufficiently given by the rotation resistance of the winding shaft 21.

After that, the wall curtain film M in a service state
When removing, the wire 4 is loosened and the baton 5 is lowered. At the same time, an electric motor 25 is mounted on the winding device 20, and the winding shaft 21 is rotated by the electric motor at a peripheral speed substantially equal to the descending speed of the wall curtain film to wind and store the wall curtain film. Finally, the baton 5 and the sub-baton 10 at the upper end of the film are separated, and the winding device 20 is set in a transportable state together with the wall curtain film M, and the winding device together with the winding device is loaded on a transporting trolley by a forklift or the like, and a predetermined storage such as in a warehouse Store in place.

FIG. 14 shows a means for arranging the wall curtain film M at the site of the spectator seat, which is always prepared in a dome building of a large space used for multiple purposes. In short, the above-described winding device 20 prepares the support base 50 having an appropriate height and horizontally arranges it for use with respect to the front descent and the step-like structure set in the spectator seat.
