〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

In FIGS. 2 to 6, reference numeral 1 denotes a cylindrical support member, which has a circular cross section as shown in FIG. 6 obtained by subjecting a strong base cloth to resin coating and flameproofing. It is a flexible hollow body that is welded and finished so as to have an arcuate outer shape as shown in FIG. 3, and as shown in FIG. 2 and FIG. An air injection / exhaust valve 2 is provided.

The air injection / exhaust valve 2 is similar to that used for the floating bag, and has a knurled rotating wheel 3 (second
The air injection / exhaust valve 2 can be closed or opened by rotating (see the drawing).

Bands 4 are attached to both ends of the tubular support member 1 as shown in FIG.
Has a double bottom.

When the air injection / exhaust valve 2 is connected to the discharge port of the small blower by a hose (not shown), the rotary wheel 3 is rotated to open the air injection / exhaust valve 2, and air is injected into the cylindrical support member 1, the cylindrical support member No. 1 swells as the internal air pressure increases, and the whole gradually becomes an arc shape and becomes hard.

After injecting air of an appropriate pressure into the inside of the cylindrical support member 1, the operation of the small blower is stopped and the rotary wheel 3 is rotated to close the air injection / exhaust valve 2 and then connected to the discharge port of the small blower. When the hose that opens is removed from the air injection / exhaust valve 2, air having an appropriate pressure remains sealed inside the tubular support member 1 so that the tubular support member 1 maintains an arcuate shape. Become.

As shown in FIGS. 2, 3, 5, and 6, a tape 6 is adhered in the longitudinal direction on the arcuate outer side of the cylindrical support member 1, and a large number of tapes 6 are arranged at intervals. Hole 7 (3rd
(See FIGS. 5, 5 and 6). A short tape 8 is adhered to the middle of the arcuate inner side of the tubular support member 1 as shown in FIGS. 3, 4, and 6, and the tape 8 has a hole 9 (see FIG. 6). ) Has been drilled.

When the rotary wheel 3 is rotated to open the air injection / exhaust valve 2 in a state where air is enclosed in the tubular support member 1, the air enclosed in the tubular support member 1 is released to the outside. Can be discharged. At this time, if the air injection / exhaust valve 2 is connected to the intake port of the small blower by a hose (not shown), the air enclosed in the tubular support member 1 can be rapidly exhausted. The tubular support member 1 from which the air inside has been discharged is folded into a small volume and is not bulky,
You can easily carry them one by one.

After the building scaffolding 10 which is slightly higher than the building to be built is installed around the construction site as shown in FIGS. 2 to 4, the tubular support member 1 is built in a soft state in which air is not enclosed. Transport to the top of scaffolding 10. Then, the air injection / exhaust valve 2 is connected to the discharge port of a small blower on the ground by a hose, and air is injected into the inside of the tubular support member 1 to inflate the tubular support member 1 and harden the tubular support member 1.

As a result, the tubular support member 1 has an arcuate shape as shown in FIG. 3, so that while arranging a plurality of tubular support members 1, 1 ... on the upper part of the building scaffold 10 as shown in FIG. Both ends of the cylindrical supporting members 1, 1 ... Are respectively locked by the bands 4 to the horizontal members 11 on both upper sides of the building scaffolding 10 as shown in FIG.

Since the distance between the horizontal members 11, 11 has various dimensions depending on the building, it is necessary to prepare the tubular support member 1 of a size corresponding to the dimension in advance, but for a slight dimensional difference By bending the tubular support member 1, both ends of the tubular support member 1 can be locked to both upper sides of the building scaffold 10.

Further, since the length of the horizontal member 11 of the building scaffold 10 also has various dimensions depending on the building, in the case of the building scaffold 10 having a long horizontal member 11, a cylindrical support that locks to the horizontal members 11 on both sides of the upper part. In the case of a building scaffolding 10 in which the number of members 1 is large and the length of the horizontal members 11 is short, the number of tubular support members 1 to be locked to the horizontal members 11 on both sides of the upper part is reduced, and a plurality of cylinders are arranged. -Shaped support members 1, 1 …… Be careful not to open or close the gap between them.

After arranging the plurality of tubular supporting members 1 on the upper part of the building scaffolding 10 in this manner, the string 12 is attached to the hole 9 (see FIG. 6) of the tape 8.
2 and 4, the string 12 is stretched, and the intermediate portions of the plurality of tubular support members 1 are connected to each other by the string 12.

Further, an intermediate portion of the tubular support members 1 at both ends of the plurality of tubular support members 1 arranged side by side is connected to the horizontal member 13 above the building scaffolding 10 by the string 12 as shown in FIGS. 2 to 4. .

At this time, by appropriately adjusting the stretched length and the pulling force of the string 12, the arcuate shape of all the tubular support members 1 is maintained within the vertical plane.

Next, a tent of a size suitable for the planar shape of the building scaffolding 10.
The tape 16 having the holes 14 on the lower surface of the tent 14 as shown in FIG. 6 is provided by disposing 14 on the tubular support member 1 to the upper part of the building scaffolding 10 as shown in FIGS. 3 and 4. Glue the holes 7,15
Is tied up with a string or the like, and an enclosure 17 is installed around the building scaffolding 10 as shown in FIG.

In this way, the tent 14 is supported by the plurality of tubular support members 1 and covers the upper part of the building scaffolding 10, so that the construction work can be carried out inside the building scaffolding 10 without being affected by rain and snow.

When roof construction or rooftop construction is completed and it is no longer necessary to cover the upper part of the building scaffolding 10, the tent 14 is removed, the rotary wheel 3 is rotated to open the air injection / exhaust valve 2, and the inside of the tubular support member 1 is removed. The air enclosed in is discharged to the outside, the band 4 is detached from the horizontal member 11 of the building scaffolding 10, the string 12 is unwound, and the tubular support member 1 is folded and carried out individually.

The present invention can be applied to both buildings and wooden buildings.

〔The invention's effect〕

According to the present invention, both ends of the tubular support member 1 are locked to both sides of the upper portion of the building scaffolding 10, and the individual tubular support members 1 arced by the injection of air are held in the vertical plane by the string 12. An arcuate work space can be secured above without falling down, and the tent 14 supported by the tubular support member 1 covers the upper part of the building scaffolding 10 in an arc shape that does not give a feeling of oppression and rain and snow. Since it is prevented, the interior of the building scaffolding 10 is not affected by the weather, has less oppressive feeling, and has an effect of advancing the construction work.

The temporary roof is light and easy to handle because it is divided into a plurality of flexible hollow tubular support members 1, cords 12 and tents 14, and it is easy to transport and install and remove. Even in this case, since the cylindrical support members 1 can be lifted and lowered one by one or transported, there is an effect that a large amount of force is not required for lifting and lowering and carrying work, and safe work can be performed at a high place.

Further, since both ends of the tubular support member 1 are locked to both upper sides of the building scaffold 10 by the bands 4, there is an effect that the tubular support member 1 can be easily attached to and detached from the building scaffold 10.
