DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for folding and installing a large wall curtain membrane and a storage cart according to the present invention are shown in FIG.
It is preferably implemented to enable the multipurpose use of the internal space of a large dome building as shown in FIG. That is, when removing the large wall curtain membrane M containing glass fibers in the service state as shown in FIGS. 8 and 9, the large wall curtain membrane M containing the glass fiber is folded and stored in the storage cart 1 as shown in FIG. Is loaded on the storage trolley 1 together with the baton 2 attached thereto, and the storage trolley 1 is run and stored in a predetermined storage location. Conversely, the wall curtain film M
When the storage cart 1 is used, the storage cart 1 is pulled out from the storage location together with the storage trolley 1 and towed to run, and the storage trolleys 1 are arranged on the floor 15 immediately below the use position along the partition pattern X or Y shown in FIG. And the wire 3 lowered from the ceiling of the building etc.
Is connected to the hanging member 4 of the baton 2, and the wire 3 is wound up by a winch or the like (not shown) to vertically raise and set up the wall curtain film M to a predetermined height.

In order to easily carry out the above-mentioned folding and setting method by a mechanized method, the storage cart 1 for the large wall curtain film is constituted as follows. That is, as shown in FIG. 1, FIG. 2 and FIG. 3, the storage trolley 1 is an elongated trolley having a length substantially equal to the width dimension (for example, 10 m) of one wall curtain film M. As shown in the figure, a film storage section 5 having a substantially U-shaped groove and having an open upper end is provided. The film storage section 5 is formed by attaching vertical guide bars 9 at an appropriate pitch in the longitudinal direction to the inner side surfaces of the right and left bogie frames 8, which stand vertically along both side edges of the bogie base 7. Have been. Casters 11 for running are installed at four places (but not limited to four places) before and after the lower surface of the bogie base 7. On the lower surface near both front and rear ends of the bogie base 7 (but not limited to this position), as an example, a fixed stand 12 having a configuration in which the height can be freely adjusted by a screw mechanism is installed vertically downward. ing.

Therefore, by connecting the storage cart 1 to the towing vehicle 13 as shown in FIG. 6, the storage cart 1 can be towed while carrying a heavy wall curtain film and carried to and stored in a warehouse or the like, or pulled out from the warehouse or the like. To the use location, and can be positioned at the use position. When the use position is determined, the fixed stand 12 is extended downward to change the support from the casters 11, and the storage cart 1
Can be fixed on the floor 15 for use.

In the longitudinal direction of the center of the film storage portion 5 of the storage truck 1, a saddle bar 6 contributing to the sorting and storage of the wall curtain film M is provided with a support 10 having a lower end fixed to the center of the base 7 of the truck base. Thus, the film storage portions 5a and 5b, which are supported substantially horizontally at a required height and are bisected by the saddle bar 6, are formed on both sides. The saddle bar 6 has a length at least equal to the width dimension of the wall curtain film M, and leaves a central top portion of the wall curtain film which is divided into the film storage portions 5a and 5b on both sides and folded as shown in FIG. 3 over the entire length in the width direction. It is configured to support without. In particular, both ends of the saddle bar 6 have a wrap length S required for suspending the wall curtain film M to the partition position.
As shown in FIG. 1, the film is protruded from the end of the bogie frame (bogie frame 8 and bogie base 7) by a length L slightly larger than the wrap length S of the membrane. The protruding portions at both ends are slightly curved in a direction opposite to the horizontal direction from the center line.

Therefore, as shown in FIG. 1, the plurality of storage carts 1, 1 arranged to be transported to the position immediately below the partition pattern for use, as shown in FIG. Are arranged so as to be bent symmetrically on both sides of the center line, whereby the wrap length S of the wall curtain film M can be easily secured. Storage cart 1
Also, on both sides of the position higher than the saddle bar 6,
A pair of right and left sorting bars 20 and 21 for folding the wall curtain film M in a sorting state are provided. The distribution bars 20 and 21 are basically set to a length approximating the width dimension of the wall curtain film so that the distribution effect of the wall curtain film M is not insufficient. In the case of the illustrated example, the distribution bars 20, 21 equal to the length of the bogie frame are:
Each of the rotating arms 22 having a plurality of inverted L shapes is supported horizontally at one end (tip) of the rotating arm 22. On the other hand, the drive shafts 24 arranged in the longitudinal direction of the bogie frames 8 on both sides forming the film accommodating portion 5 are rotatably installed by bearings 23 fixed to the bogie frames 8. 24
The other end (base end) of the rotating arm 22 is fixed to the arm. As a drive device for rotating the drive shaft 24 and thus the reciprocating bars 20, 21 by a required angle reciprocating rotation (swing),
The base end of the crank arm 25 is fixed to the drive shaft 24,
The distal end of the crank arm 25 is connected to an output shaft 26a of a cylinder type actuator 26 that moves linearly. As shown in FIG. 2, the actuator 26 is arranged vertically upward at a position immediately adjacent to the bearing 23, and a support shaft (trunnion shaft) 33 at an intermediate portion of the cylinder body is mounted on a support frame 31 provided at the same position. A slight tilt is supported.

Therefore, generation of a harmful bending action on the drive shaft 24 by the linear acting force of the actuator 26 is prevented as much as possible by the operation of the bearing 23, and the actuator 2
6 is converted into a reciprocating rotational motion of the drive shaft 24 via the crank arm 25. A positioning 27 that abuts on the saddle bar 6 is provided at an intermediate position of the rotary arm 22, thereby preventing the distribution bars 20 and 21 from overswing. At the same time, the positioning 27 abutting against the saddle bar 6 presses and fixes the wall curtain film M against the saddle bar 6 to ensure that the wall curtain film M is sorted. A control circuit is configured so that the sorting bars 20 and 21 on both sides reciprocate in an alternate order under the drive control of each actuator 26. However, the drive device is not limited to the above configuration, and a drive mechanism using a rotary motor, a configuration to which a link mechanism is applied, or the like can be appropriately selected and implemented.

When the storage cart 1 having the above structure is placed at a position immediately below the partition pattern formed by the wall curtain film M and the actuator 26 is started in advance when the wire 3 is loosened and lowered, the wall curtain film is moved as shown in FIGS. It is folded and stored one after another. For the wall curtain film M that slowly descends at a speed of about 2 m per minute, the left sorting bar 20 first rotates clockwise, and the positioning 27 abuts on the saddle bar 6, and the sorting bar 20 is positioned above the saddle bar 6. Keep the posture while overswing for a while. As a result, the sorting bar 20
Of the right side membrane storage part 5 in the wall curtain membrane M by the guide action of
Create a flow N that hangs down in b (see FIG. 4A). At this time, the distribution bar 21 on the right side in the drawing is stopped while the rotating arm 22 is in a vertically upright posture. Then, at the same time as the left sorting bar 20 performs the counterclockwise rotation and escapes, the right sorting bar 21 starts counterclockwise rotation (FIG. 4B). When the rotary arm 22 of the left sorting bar 20 stops in the vertical upright position, the right sorting bar 21 hits the positioning bar 27 against the saddle bar 6 and the sorting bar 21 overswings above the saddle bar 6. Keep your posture for a while. As a result, a flow F is formed in the wall curtain film M by the guiding action of the distribution bar 21 and hangs down into the left film storage portion 5a (see FIG. 4C). Thus, the left and right distribution bars 20 and 21 reciprocate and rotate in an alternate order at a fixed time interval under the control of a timer or the like, so that the long wall curtain film M is disposed on both sides of the saddle bar 6.
a, 5b are alternately suspended in a substantially equal length and folded in a distributed state and stored compactly.

As a preferred means for securing an emergency evacuation opening or passage in the partition by the wall curtain film M at the time of emergency evacuation such as an earthquake or fire, the storage cart shown in FIG. 7 is proposed. In this configuration, a protruding portion (end portion) 6 ′ of the saddle bar 6 from the bogie frame is connected by a hinge 51 that can be bent in a vertical direction, and the protruding portion 6 ′ is supported by a stay 50 from below. ing. Therefore, an emergency evacuation opening or passage can be formed by removing the stay 50 and bending the protruding portion 6 'together with the membrane downward as shown in the dotted line as needed in an emergency.

A control panel 30 is provided on the storage trolley 1 for controlling the drive of the actuator 26 as described above. The power source may be mounted in advance on each truck, or may depend on an external power supply, a hydraulic device, or the like prepared in a building or the like. As described above, the folded portion of the wall curtain film M folded in the alternately distributed state is:
Only the U-turn while hanging down by the action of its own weight does not receive the film load of the particularly folded portion, so there is no risk of damaging the glass fiber. The folding and storing operation of the wall curtain film M is finally performed by receiving the baton 2 on the member 28 which is bridged over the upper ends of the bogie frames 8 on both sides and bound as shown by the dotted line in FIG. Then, the connection between the hanging member 4 and the wire 3 of the baton 2 is released, and the baton 2 is loaded on the storage trolley 1.

The wall curtain film M, which is stored in a folded state in the storage truck 1 in this manner, is towed by the towing truck 13 as shown in FIG. To the designated warehouse, etc., and store the entire cart. To this end, towing brackets 29 are provided at the front and rear ends of the storage cart 1. Conversely, when it becomes necessary to use the stored wall curtain membrane, the corresponding storage cart 1 is also pulled out of a warehouse or the like by a tow truck, towed and traveled, carried to a use place in the building, and designed in advance. The required number of units are sequentially arranged in a serial arrangement at a position immediately below the partition pattern along the partition pattern. At this time, when the adjacent films are wrapped with each other, the adjacent ends are wrapped by using the curvature of the both ends of the saddle bar 6 to secure the wrap length S of the film. When the position of each dolly is decided,
The caster 11 is operated by extending the fixed stand 12.
And the position is fixed exactly on the floor 15. Thereafter, the wire 3 prepared in advance on the ceiling of the building is lowered and connected to the hanging tool 4 of the baton 2.
The wall curtain film M is lifted by winding up the wire 3. At this time, the right and left sorting bars 2 of the storage cart 1
Reference numerals 0 and 21 indicate that the respective rotating arms 22 are in a state of standing upright as shown in FIG. 4B or FIG. Therefore, the wall curtain film M hung up by the wire 3 is smoothly unfolded and automatically hung up in the exact opposite order of the folding, and does not require any manpower.

As described above, the wall curtain film M
Is suspended at an appropriate height in a partition pattern according to the intended use of the interior space of the building. In any case, the storage trolley 1 is used while being fixed at the initial position. In that case, a sheet that covers and hides the storage cart 1 from the field of view is used as necessary. Next, in order to use as a concert venue, the wall curtain film M is lifted up to its full length for sound insulation and light blocking effect, and as a result, when the lower end of the film fluctuates and shakes, or when it is in trouble. When it is desired to apply an appropriate tension to the lowered wall curtain film M, the method of FIG. 5 is suitably implemented. First, a tension bar 32 used for applying tension is firmly fixed by welding in a longitudinal direction of, for example, a center portion of the truck base 7 of the storage truck 1. At the lower end of the wall curtain film M, a retaining rope 40 having a length extending over the entire width thereof is provided. Further, a connecting bar 41 having a uniform cross-sectional shape is provided at both upper and lower ends of a C-shaped groove having a slit having a diameter substantially the same as the outer diameter of the retaining rope 40 and having a width capable of passing a film over the entire length. The connecting bar 41 has a length equal to the width dimension of the wall curtain film M, and the retaining rope 40 is fitted into one of the C-shaped grooves while sliding in the axial direction to connect the two. As a result, in the other C-shaped groove facing downward, a rubber band rich in elasticity (however, a coil spring or the like may be used as long as the elasticity is a string shape, and the rubber band is not limited).
A short support shaft 43 provided at one end of a connecting band 42 using
While sliding in the axial direction. In this manner, a large number of connecting bands 42 are attached in the longitudinal direction of the connecting bar 41, for example, at a pitch of about 1 m. The connecting band 42
The other end is provided with a hook 44 configured to be hooked and connected to the tension bar 32. In short, when the lower end of the lifted wall curtain film M hangs in the film storage portion 5 of the storage trolley 1 as a free end and swings, the tension of the hook 44 of each of the connection bands 42 is pulled while pulling the rubber band. Connect to bar 32. Alternatively, the hook 44 of each connecting band 42 is routinely connected to the tension bar 32 in advance, and in such a state of use, an adjustment is made to slightly increase the winding force of the wire 3, and a wall is formed by utilizing the elasticity of the rubber band. The necessary tension is easily and safely applied to the curtain film M, the film is set in a taut state, and the lower end of the film is restrained.

[0024]

According to the method for folding a large-sized curtain film and the storage cart according to the present invention, the large-sized curtain film containing glass fibers is inadvertently bent to a radius of curvature smaller than a predetermined radius to damage the glass fibers. There is no danger. The folded state of the membrane can be made as compact as possible, while at the time of construction, it can be mechanically smoothly spread, and the heavy and bulky wall curtain membrane can be easily removed by a mechanical method. In addition, the vehicle can be towed while being loaded on the trolley, stored in a warehouse or the like, and can be pulled out and used whenever necessary. Therefore, the demand for the multipurpose use of the building can be sufficiently satisfied, and the labor-saving construction work can be efficiently performed.
