Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a foot for a scaffolding for a roof used when building a roof.

(Prior Art) When building a house, for example, for the outer wall of the second floor, an operator climbs onto the roof and applies mortar, etc.
There is a case where it is necessary to work on the roof, and in such a case, from the viewpoint of workability, safety, etc., it is common to assemble a scaffold for work by using a plate on the roof.

Conventionally, when assembling a scaffold for work on a roof, a scaffold board was placed on a roof tile and fixed with ropes and wires.

(Problems to be solved by the invention) However, in the conventional work scaffold, if a general flat scaffolding board that is also used for scaffolding other than the roof is used,
Since the planks will be placed on the roof with an inclination, it is necessary to maintain an unreasonable posture while working on the scaffolds, which easily causes fatigue and is inconvenient to move on the scaffolds. When a work load, for example, a mortar box is placed on top of the mortar, the mortar may flow out, which may cause the load to collapse, leaving some improvements in workability and safety.

There is also a method in which the scaffolding board is formed in advance in a triangular shape in cross section corresponding to the inclination of the roof, and the inclined surface of the scaffolding board is along the inclined surface of the roof to provide a horizontal working scaffolding. Since the boards are bulky and heavy, they are inconvenient to transport, they are dedicated to the roof, they cannot be used for scaffolding other than the roof, and there is a problem that scaffolding boards other than the roof must be prepared separately. It was

As a method for solving the above problems, it is proposed to use a flat scaffolding plate and to provide legs for horizontally holding the scaffolding plate, but what kind of structure should the legs have?
Another problem is how to fix it on the roof.

In view of such a point, an object of the present invention is to provide a scaffolding leg for a roof, which can hold a flat scaffolding plate horizontally on a roof and can greatly improve workability and safety.

(Means for Solving the Problems) Therefore, the scaffolding leg for a roof according to the present invention is placed and locked on a sloping roof tile, and a roof for placing the scaffolding plate substantially horizontally on the roof. In the scaffolding leg for use, the leg body has a horizontal side portion and a vertical side portion made of a rigid metal plate,
The rear end of the horizontal side is connected to the upper part of the vertical side at a substantially right angle, and the tip of the horizontal side and the lower end of the vertical side are bent and placed on a roof tile. The horizontal side is supported almost horizontally on the roof tile by the vertical side so that the scaffold plate can be placed, while the inclined side is provided between the placing pieces of the horizontal side and the vertical side. The slanted side portion is fixed and is made of a flexible thin metal plate so that substantially the whole of the slanted side portion is deformed along the roof tile so that it can be placed or come into surface contact, and the tip of the slanted side portion extends forward. It is characterized in that a locking piece portion that is provided and locked to the upper edge of the roof tile 2b is bent.

The vertical side portion and the horizontal portion of the leg body may be made of any rigid metal plate, for example, an iron plate or a steel plate can be used. In this case, it is preferable to perform surface treatment, for example, plating, in terms of appearance and because the scaffold is often left for a long period of time.

The slanted side part may be a thin metal plate having flexibility, but it should be left for a long time as described above, and the tip locking piece part should be the upper end of the side roof tile through the gap between the upper and lower roof tiles. For example, a stainless thin plate is preferable because it is locked to the edge.
The slanted side portion is made of a flexible material because the total length of the leg body is larger than the size of the roof tile, and when the slanted side portion of the leg body is placed over three or more roof tiles, the load is This is so that not only the roof tiles of a part but also the roof tiles can be received in a distributed manner.

Since there are various roof inclinations, it is desirable to provide the vertical side portions of the leg body so that the distances between the rear ends of the horizontal side portions and the inclined side portions can be adjusted. Therefore, the rear end of the horizontal side is bent downward at a substantially right angle, and a plurality of mounting holes are formed in the bent part and the upper part of the vertical side at intervals in the vertical direction. It is preferable that the mounting holes of the vertical side are aligned with each other, the bolt is inserted and screwed into the nut, and the rear end of the horizontal side is connected to the vertical side so that the height can be adjusted.

(Effects and effects of the invention) The leg body is formed into a substantially right-angled triangle, placed on the roof tile of the leg body and locked, and the scaffold plate is placed on the horizontal side portion of the leg body. A substantially horizontal working scaffold can be formed on the top of the work, and workability and safety can be greatly improved.

Also, if you can adjust the height of the rear end of the horizontal side of the leg body,
Even if the slope of the roof is different, the horizontal side and the roof tile above can be located at the same position, and a substantially horizontal work scaffold can be formed.

By the way, since the roof tile has a special shape, cracks are likely to occur if the load is applied unevenly to only part of it, especially the central part, but the inclined piece of the leg body deforms along the roof tile. , The leg body is larger than the roof tile, and even when it is placed over multiple roof tiles, the sloped piece is placed on all the roof tiles or comes into surface contact, so that the load from the scaffolding plate is on the roof. The roof tiles will not be cracked because they will be scattered throughout the tiles.

Further, since the leg body is manufactured by combining the metal plate and the metal thin plate, it can be manufactured easily and at low cost.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings. 1 to 3 show a roof scaffolding leg according to an embodiment of the present invention. In the figure, a plurality of roof tiles 2 are laid on a roof 1, and a work scaffold 5 composed of three or four scaffold legs 3 and a flat scaffold plate 4 is provided on the roof 1.

The scaffolding leg 3 is composed of L-shaped first and second iron plates 6 and 7 and a thin stainless plate 8, and two bolt holes 6a and 6b are formed in the vertical wall portion of the first iron plate 6 to form a second iron plate. Three bolt holes 7a, 7b, 7c are respectively formed in the vertical wall portion of 7, and the first and second iron plates 6, 7 are the bolt holes 6a, 6b and the upper two bolt holes 7a, 7b. Alternatively, the bolt 9 is inserted into 7b and 7c, and this is screwed into the nut 10 so as to be coupled to each other. A hole for nail driving is formed in the upper end of the vertical wall of the second iron plate 7.
7d is formed.

Further, a rivet or the like is fixed to the front end portion and the rear end portion of the stainless steel thin plate 8 at the front wall bent portion of the horizontal wall portion of the first iron plate 6 and the bottom wall portion of the second iron plate 7, respectively. Is bent downward, the tip bent portion 8a of the thin stainless steel plate 8 is inserted into the gap between the upper and lower roof tiles 2a and 2b, and is locked to the upper edge of the lower roof tile 2b. It is placed on the roof tile 2b and the roof tile 2c below it. The scaffolding plate 4 is placed on the raised portions of the roof tiles 2a, 2b above the roof tile 2b and the rear end of the horizontal wall portion of the first iron plate 6, and is fixed to the vertical wall portion of the second iron plate 7 by the nail 13. Has been done.

As described above, the first and second iron plates 6 and 7 and the stainless steel thin plate 8 constitute the leg body 11 having a substantially right triangular shape composed of the horizontal side portion, the vertical side and the inclined side portion, and the vertical side portion. Is provided so that the distance between the rear ends of the horizontal side portion and the inclined side portion can be adjusted, and the tip portion of the thin stainless plate 8 is the leg body 11
The locking piece 12 is fixed to the tip.

Next, the usage method will be described. When assembling the scaffold 5 for work on the roof 1, the upper roof tile 2a is slightly lifted, the tip locking piece 12 of the scaffold leg 3 is inserted, and this is locked to the upper edge of the lower roof tile 2b, and the stainless steel is used. Roof tiles 2b and 2c
Place it on the top, and similarly install two or three scaffolding legs 3 on the roof tile 2 at the same position, and scaffold the upper part of the roof tile 2 and the horizontal side of the scaffolding leg 3 above it. The plate 4 may be placed substantially horizontally and fixed to the scaffolding leg 3 with nails 13.

Therefore, it is possible to assemble the scaffold 5 for work which is substantially horizontal, it is not necessary to keep an unreasonable posture on the scaffold 5 during the work, and it is easy to move on the scaffold 5 and further work on the scaffold 5 is possible. Even if a load is placed, the load does not collapse and workability and safety can be greatly improved.

Further, a general flat scaffolding board 4 which is also used for scaffolding other than the roof can be used, and it is very easy to transport.

Further, since the scaffolding leg 5 is configured by using the bent iron plates 6 and 7 and the stainless thin plate 8, the structure is simple, the manufacturing is very easy, and the cost does not increase.

By the way, as shown in Japanese Utility Model Laid-Open No. 55-44938, a horizontal U-shaped portion, a vertical L-shaped portion and an inclined L-shaped portion are formed of a metal plate having a U-shaped cross section with rigidity, and a rubber member is formed at the rear end of the inclined L-shaped portion. A scaffolding leg provided with a foot portion of is proposed. However, in order to place a large work load on the scaffolding plate, it is necessary to make the scaffolding legs large, and when the scaffolding legs are placed over three or more roof tiles, the upper roof tiles have inclined pieces. However, the sloped piece does not contact the middle and lower roof tiles, only the foot is placed on the lowermost roof tile, and a large load is applied to part of the sloped piece. It is necessary to receive only the part where the upper roof tile placed and the foot part of the lowermost roof tile are grounded, and the load concentrates on such a part, and the roof tile is likely to crack.

On the other hand, in the scaffolding leg of this example, the inclined piece part is deformed along the roof tiles and almost the whole is placed on all the roof tiles, so that a large load is also distributed to all the roof tiles, The roof tile will not crack.

Further, as disclosed in Japanese Utility Model Laid-Open No. 63-73442, a structure has been proposed in which the tip side of the scaffold plate is placed on a roof tile and the rear end side of the scaffold plate is received by pipe legs. There is. In this case, the tip portion of the scaffolding plate is received by a plurality of roof tiles in the width direction, but the legs are grounded only to a part of the two roof tiles below the rear end of the scaffolding plate. The large load on the side concentrates on the two roof tiles, and there is concern that the roof tiles may crack.
