The fastening members 16b of the toy pieces 12 are provided with the same number of fasteners 16a provided on the back side of the right end side of the scaffolding sheet 10 at the same position with respect to each side so that they can be fitted and fastened to each other. It is arranged in the form.

At two corners of the rear end side (the other long side of the other side) of the scaffolding sheet 10, there is provided a support hole 17 having a diameter large enough to insert a standing support 21 used for the scaffold.
A string 18 as a striated member is provided close to.

On the other hand, at two corners of the front end side (one long side),
A cap 19 having a diameter of a size that the front support column 20 is inserted and securely attached and does not move is opened on the back side of the scaffolding sheet 10 and provided. Prop upright 20
The bottom surface of the cap 19 with which the head of the cap abuts is substantially flush with the surface of the sheet member 15. A hole is formed at a position near the center of the sheet member 15, and a drain port 13 is provided. Further, a box-shaped drain toy 14 is provided at a lower portion on the back side of the drain port 13. The drainage toy 14 is made of the same material as the sheet member 15. The top surface is opened toward the drainage port 13, the side surface F is opened toward the rear end surface A of the scaffolding sheet 10, and fixed by sewing or fusing, It is attached. As described above, since the drainage toy 14 and the toy piece 12 are made of the same material as the sheet member 15, the scaffolding sheet 10 can be folded, easily carried and stored, and the handling is easy.

A method of mounting the scaffold sheet 10 shown in such a plan view on a scaffold will be described. First, the building scaffold
As shown in FIG. 3, the erecting columns 20 are erected at regular intervals along the building to be constructed, and the erecting columns 21 are arranged in parallel to them at regular intervals at positions opposite to the building. Is set up. These pillars are built up according to the height of the building to be constructed. A scaffold stand (not shown) on which the operator rides is made by horizontally mounting a plate-shaped stand between two front uprights 20 and two rear uprights 21, and a work place in the scaffold. Becomes

The vertices of the scaffold assembled as described above expose the heads of the columns. The two pillar holes 17 in FIG. 4 are passed through the heads of two standing pillars 21, and are tied and fixed to the standing pillar 21 with a string 18.
Two caps 19 are put on the head of the upright support 20 on the opposite side. With this, a scaffold sheet 10 can be used to form a roof in which the standing pillar 21 side is lower than the front standing pillar 20 side with respect to the four pillars. If the scaffold is built with four or more columns over a wider area,
The scaffold sheet 10 is used by being laterally connected by a connecting portion. Specifically, the adjacent sheet connecting holes 11 of the adjacent scaffolding sheets 10 are passed through straps 22 and tied together. Further, the fastening member 16b of the toy piece 12 is connected to the adjacent scaffolding sheet 10 by being fastened to the fastening 16a provided on the back of the right end side thereof.
A roof covering the entire scaffold can be formed by fitting the pillar hole 17 and the cap 19 into the pillar scaffold head of the scaffold and mounting the connected scaffold sheet 10 as described above. At this time, since the bottom of the cap 19 and the seat member 15 are substantially on the same plane, the head of the upright support 20 and the seat member 15
Are substantially the same. On the other hand, since the rear support column 21 has its head protruding from the support hole 17 and is connected to the rear support column 21 with a string 18, the sheet member 15 exists at a position below the head of the rear support column 21. become. Since the height of each of the columns is substantially the same, and the heads of the rear column 21 and the front column 20 are substantially on the same plane, the seat member 15 forms a slope that becomes lower in a direction away from the building. Will be.

In the case where the rear stand fixing portion is constituted by the string 18 and the support hole 17, the position of the rear stand 21 to be bound by the string 18 can be changed arbitrarily, so that the height of the head of the rear stand 21 is limited. There is no. The scaffolding sheet 10 connected in this way is a toy made of a toy piece 12 having a semicircular slack, which is joined by a fastener 16a and a fastening member 16b below a connecting portion which is a joint between adjacent scaffolding sheets 10. Can be done. A drain 13 is provided in the vicinity of the center, and a toy by a drain toy 14 is provided below the drain 13.

When the scaffolding sheet 10 is thus mounted on the scaffold, it is securely fixed to the four pillars by the cap 19, the pillar hole 17 and the string 18, so that it does not come off due to wind or the like. Also, the rainwater that has fallen from the joint between the scaffolding sheets 10 is received by the toy by the toy pieces 12 provided thereunder, and further collected on the toy pieces 12 because the toys are attached to the scaffold with an inclination. Precipitation is drained down the slope, opposite to the building. Conventionally, rainwater was easily collected in the central portion of the sheet, but was collected in a drainage toy 14 thereunder through a drainage port 13 provided near the center,
Further, like the toy by the toy pieces 12 described above, the water flows in a downward direction and is drained away from the building. As described above, the work place in the scaffold is not wet by the precipitation, and the work can be performed without being affected by the weather.

In general, a sheet 30 is provided on the side surface of the scaffold to prevent the work tool from falling outside and to protect the worker from the weather. If the scaffolding sheet 10 is stretched so as to hang outside the side sheet 30 as shown in FIG.
The precipitation on the scaffolding sheet 10 and the toys from the toy pieces 12 and the falling down from the drainage toys 14 fall down along the sheet 30 stretched on the side, so that the accumulated precipitation bounces or scatters to the outside. It does not wet pedestrians unnecessarily.

Further, in order to prevent the side 35 of the building from being wet by the rain, it is preferable to make the eaves 23 for protecting the side 35 of the building from the rain. The seat member 15 is attached to the upright support 20.
Is provided. The strut arm 25 extends upward toward the side 35 of the building, and the sheet member 15 is hung thereon and held. This creates an eaves 23 on the scaffold and does not wet the sides 35 of the building.
In both cases where the shape of the roof of the building is the roofs 40 and 45 in FIG. 3, the eaves 23 extend toward the side 35 of the building, and further lower from the side 35 of the building toward the outside. Because of the inclination, the drainage of precipitation is performed efficiently.

As the post-fixing portion of the post, besides the method of providing the post hole 17 and tying it to the post-supporting column 21 with the string 18 as described above, a cap may be used similarly to the front fixing portion. good. In this case, with respect to the surface of the sheet member 15,
The inclination can be made by changing the position of the bottom surface in the cap where the head of the support comes into contact with the front fixed portion and the rear fixed portion. In addition, both the front fixing portion and the rear fixing portion may be configured by the support hole and the string. In this case, the position where the sheet member 15 is fixed by being tied to the support with the string is higher in the front standing fixing portion than in the rear standing fixing portion. Further, as the combination of the fastener 16a and the fastening member 16b to be fastened, a pair of twist hooks or a pair of concave and convex snaps can be used.

The size of the scaffolding sheet 10 and the positions of the holes and the like associated therewith are variously changed according to the size of the pillars of the scaffolding, and further, sheet members, toys, drainage toys,
The shape, material, position, and the like of the connecting portion, the fixing portion, the fastener, and the like are not limited. As described above, the present invention has been described variously with reference to preferred embodiments. However, the present invention is not limited to the embodiments, and it is needless to say that many modifications can be made without departing from the spirit of the invention. That is.

[0022]

When the scaffold sheet according to the present invention is used for a roof of a scaffold, the sheet member can be inclined by simply attaching it to a support which is a framework of the scaffold, and the sheet can be inclined by precipitation. Drainage can be efficiently performed without distortion of the entire member, and the function as a roof can be sufficiently achieved. Thereby, the work place in the scaffold can be protected from precipitation, and work efficiency can be improved. Furthermore, since it can be securely fixed to the support of the scaffold and can be attached, it does not flutter or fall off due to wind etc., and leave it in a state of being worn with peace of mind even when unmanned at night etc. Can be. This also eliminates the hassle of removing the scaffolding sheet.

Further, by attaching a toy under the joint between the scaffold sheets, it is possible to prevent the rain from leaking from the joint to the work place in the scaffold. Good drainage is achieved. Further, by forming an eave toward the building, it is possible to reliably protect the side portions such as the wall surface of the building from precipitation.
