(Prior Art) When constructing a house, first, the roof is roofed, and then the work on the wall surface is started. Therefore, for example, for the outer wall of the second floor, it may be necessary for the worker to work on the roof by climbing on the roof tiles and applying mortar.In such a case, workability, safety, etc. From the point of view, it is common to assemble scaffolds for work using scaffolding boards or logs on the roof.

In particular, as shown in Fig. 3, when working considerably above, scaffolding is assembled using vertical logs B1 and horizontal logs B2 for scaffolding, but fixing above log B1 is done using a purlin on the roof, etc. It is easy to do, but the lower part of the log B1 is fixed with a rope and a wire that extends horizontally in the lower direction (not shown) in the same way as the scaffolding plate, and the log B1 perpendicular to the log is fixed. Since the lower end is fixed, there is a problem that the assembling work is complicated and the safety is insufficient.

(Means for Solving the Problem) Therefore, a scaffolding log support for a tiled roof according to the present invention is a scaffolding log support for a tiled roof that is placed on a sloping tiled roof and fixes the lower end of a vertical log for scaffolding. It has at least two support legs that are placed laterally on the first and second tile roofs arranged in the vertical direction at a predetermined interval and are locked, and each support leg has a substantially triangular shape. A leg body including a horizontal side portion, a vertical side portion, and an inclined side portion, and a locking piece portion fixed to the tip of the horizontal side portion of the leg body and locked to the upper edge of the first roof tile. The horizontal sides and the vertical sides of the leg body are made of a rigid metal plate, and the tips of the horizontal sides are placed on the first roof tile and the lower ends of the vertical sides are placed on the second roof tile. The horizontal side portion can be held substantially horizontally by the vertical side portion, and the inclined side portion is made of a flexible thin metal plate. Substantially the whole is deformed and placed along the first and second tiled roofs to enable surface contact, while a support plate is placed and fixed between the horizontal sides of the leg bodies of the plurality of support legs for support. It is characterized in that a protruding annular portion with which the lower end of the vertical scaffolding log can be engaged is formed in the middle of the plate in the longitudinal direction.

The supporting leg is a scaffolding leg for a roof of the applicant of the present application (Japanese Utility Model Application No. 63-1).
No. 35709 and Japanese Utility Model Application No. 1-444182) can be used. The supporting leg uses a metal plate having rigidity on the horizontal side and the vertical side to form a rigid structure having a triangular cross section.

他方、傾斜辺部は屋根瓦との接触により変形可能である

である。
On the other hand, the inclined side portion is preferably formed so as to be deformable by contact with the roof tile. This is because the roof tile is easily cracked immediately when the load is applied improperly, and the load is dispersed and received by bringing the inclined sides into surface contact to prevent the roof tile from cracking.

Further, the support plate also needs to have the same rigidity as the leg body. Furthermore, the protruding annular portion on the support plate is preferably adapted to the cross-sectional shape of the lower end portion of the scaffold log, and it may be formed generally in a circular shape. Further, although the protruding annular portion usually adopts a bottom closed form, it may adopt a penetrating form.

According to the present invention, the support leg is formed into a substantially right-angled triangular shape, and the tip of the support leg is inserted between the overlapping roof tiles to lock the support leg on the roof tile and tilt it. Since a substantially horizontal support plate is held on the roof and a projecting annular portion is formed on the support plate, the lower end of the vertical log for scaffolding can be easily fitted into the projecting annular portion so that the scaffolding log can be used as a work platform. Can be assembled easily and quickly, and workability and safety can be greatly improved.

By the way, Japanese Utility Model Publication No. 51-64020 and Japanese Utility Model Publication No. 58-12825.
As shown in Japanese Patent Publication No. 2, a support leg structure in which all three sides of a substantially triangular shape are made of rigid members, and as shown in Japanese Utility Model Publication No. 3-4851 a front end locking plate and a rear end height adjustment support. A supporting leg structure for mounting a stand on a roof tile is known, and it is also possible to adopt such a supporting leg structure for a log support stand. However, the roof tile easily breaks easily depending on how the load is applied, and the supporting leg structure does not follow the roof tile at the inclined side of the supporting leg well, and the supporting leg structure receives the load only on a part of the roof tile. There is concern about cracks in the roof tiles.

On the other hand, in this embodiment, since the inclined side portion of the support leg 3 is formed of a flexible metal thin plate, the inclined side portion bends and follows the roof tiles 2b and 2c and comes into surface contact as a whole, The load of the support table is distributed and received. Moreover, since at least two support legs 3 are used and the support plate 4 is fixed between them to receive the load of the log B, the load is distributed to each support leg 3, and as a result, one roof tile has a problem. The load to such a level does not act and the roof tiles can be reliably prevented from cracking.
