[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective sheet stretched on the outer surface of a framework scaffold.

[0002]

2. Description of the Related Art On the outer surface of a framed scaffold assembled at a building site of a high-rise building such as a building, work materials are prevented from directly falling on a road, and for the purpose of wind protection, for example, made of canvas or synthetic resin. Protection sheet is installed.

FIG. 4 is a front view of a conventional protective sheet in a stretched state. As shown in FIG. 4, in the conventional protective sheet, the eyelets 70 are perforated at appropriate intervals along the periphery of the sheet body 1, and the rope 71 passing through the eyelets 70 is
For example, it is connected to the vertical member 81 or the horizontal member 82 of the handrail frame attached to the framework scaffold, and is stretched on the outer surface of the framework scaffold.

[0004]

However, in the above-mentioned conventional work of stretching the protective sheet, the complicated work of connecting the ropes 71 corresponding to a large number of eyelets holes 70 must be performed. Labor and time are required.

[0005] Further, it has been pointed out that the knot of the cable 71 may be loosened and the protective sheet may come off in a strong wind. The present invention has been proposed in view of the above-described conventional circumstances, and has as its object to provide a protective sheet that can be easily installed on a framed scaffold and that can be securely fixed. .

[0006]

In order to achieve the above object, the present invention adopts the following means. That is, FIG.
As shown in FIG. 3 to FIG. 3, in the protective sheet of the framework scaffold stretched on the outer surface of the framework scaffold, the vertical member 81 of the framework scaffold is provided.
A plurality of strip-shaped fixing pieces 20 for winding the sheet body 1 around the horizontal member 82 are provided on the upper side 11 and the left and right sides 12 and 13 of the sheet body 1. This is a protection sheet for a scaffolding scaffold in which a locking member 30 fixed to a tip end of the fixing piece 20 is inserted into a receiving hole 40 formed in the portion.

Further, the side edges 12, 13 of the seat body 1 are provided.
It is also desirable that the interval between the fixing pieces 20 is equal to the width of the fixing piece 20 and that the protruding positions of the fixing pieces 20 between the left and right sides 12 and 13 are staggered.

[0008]

According to the above construction, as shown in FIGS. 1 to 3, each fixing piece 20 is sequentially wound around the vertical member 81 and the horizontal member 82 of the framed scaffold, and the locking member 30 at the distal end is connected to the base end. The seat body 1 is stretched on the framework scaffold simply by inserting it into the receiving hole 40 of the section.

Further, the sides 12, 13 of the seat body 1 are provided.
Are arranged in a zigzag manner on the left and right, so that the heights of the adjacent protection sheets do not interfere with each other, and one vertical member 81 can be connected to the adjacent protection sheet 1 in the lateral direction. ′ And a common vertical member 81.

[0010]

1 is a front view of an embodiment of the present invention, FIG.
3 is an enlarged sectional view of a main part, and FIG. 3 is an enlarged front view of the main part of FIG.

As shown in FIG. 1, in this embodiment, a plurality of strip-shaped fixing pieces 20 are provided on the upper side 11 and both left and right sides 12 and 13 of the sheet body 1 and at the base end of each fixing piece 20. It has a perforated receiving hole 40 and a locking member 30 fixed to the distal end of the fixing piece 20.

When the protective sheet is stretched on a framed scaffold, the fixing piece 20 is wound around a vertical member 81 and a horizontal member 82 such as a handrail frame attached to the framed scaffold, and receives the locking member 30. It is inserted into the hole 40 and fixed. Particularly, in this embodiment, the handrail frame 82A is fixed to the vertical member 81 for worker safety, and the horizontal member 82
This handrail frame 82A is used.

The specific structure of the locking member 30 is not particularly limited, and a split pin whose diameter is enlarged after the distal end portion is inserted into the receiving hole 40 may be used. In this embodiment, as shown in FIG. 2, a shaft main body 31 having a diameter corresponding to the hole diameter of the receiving hole 40 and a right-angled triangular stopper 32 urged in the outer diameter direction at the tip of the shaft main body 31 are provided. It is configured to be provided. Therefore, when the locking member 30 is inserted into the receiving hole 40, the stopper 32 is pressed by the peripheral edge of the receiving hole 40 and retreats in the inner diameter direction of the shaft main body 31, and then returns to the locking position shown in FIG. The hole 40 is prevented from falling out.

Although the number of each fixing piece 20 per side, the mutual interval and the width are not limited, in this embodiment, the fixing pieces 2 arranged side by side with the side edges 12 and 13 of the sheet body 1 are particularly preferred.
0 is equal to the width of the fixed piece 20, and the upper end of the arrangement of the fixed pieces 20 on the right side 12 is matched with the upper end of the side 12, while the left side 13 The upper end of the arrangement of the fixing pieces 20 is moved from the upper end of the side 13 to the fixing pieces 20.
Left and right sides 12, 13 shifted downward by the width of
It is arranged in a zigzag pattern between.

By arranging in this manner, as shown in FIG. 3, one vertical member 81 is fixed to the fixing piece 20 provided on the side 12 of the left sheet body 1 and the right sheet body 1 '. It can be wound both with the fixing piece 20 provided on the side 13, and the protection sheet adjacent to each other has the same stretched height position.

In this embodiment, the strength of the seat body 1 is set such that the fixing pieces 20 on the three sides of the upper side 11 and the side sides 12 and 13 are provided.
Therefore, no securing means is provided on the lower side 14 of the seat body 1 and the seat body 1
Is set to be sufficiently larger than the distance between the upper and lower scaffold plates, and in the stretched state, the lower side 14 of the sheet body 1 is hung down inside the protective sheet stretched in the lower tier.

As described above, according to this embodiment, since all means for fixing the protective sheet are attached to the sheet main body 1, preparation of materials such as cords and the like for fixing as in the prior art is performed.
The labor for procurement can be saved, the time required for installation is reduced, and the fixing strength is improved.

Further, by arranging the fixed pieces 20 on the left and right sides in a staggered manner as in this embodiment, the tension of the left and right protective sheets adjacent to each other with respect to one vertical member 81 can be increased. The appearance can be kept beautiful without interference between the installation height positions. In addition, since the gap between the protective sheets is narrowed, the occurrence of the detachment of the protective sheets and the falling of materials and tools due to strong winds is reduced.

[0019]

According to the present invention, since the fixing piece to the framework scaffold is provided integrally with the protective sheet, the work can be performed quickly without procuring and preparing members and the like for the extension.
In addition, since the fixing piece is formed in a band shape having a fixed width, the tensioning strength is increased, and the tensioning is completed with the trouble of inserting the locking material into the receiving hole.

Further, by arranging the fixing pieces in a staggered manner on the left and right, the right and left mutually adjacent protective sheets do not interfere with one vertical member of the framework scaffold.
By aligning the extending height positions, beautiful appearance is maintained.

Further, since the gap between the protective sheets is narrowed, it is possible to more reliably prevent the protective sheet from being detached by a strong wind and from falling down of work materials and tools.
