The hypotenuse member 1 is made of a metal member having a horizontal cross section having a length of about 90 cm. The horizontal member 2 is made of a channel-shaped metal member, and the horizontal member 2 is loosely fitted in the hypotenuse member 1 so that the opening side thereof faces downward. A common support shaft 3 is inserted through the base end of the hypotenuse member 1 and the base end of the horizontal member 2 to pivotally support the hypotenuse member 1 and the horizontal member 2 so that they can be opened and closed. (Figure 3). Large diameter portions 4 and 4 are formed at both outer protruding ends of the support shaft 3.
Reference numerals 5 and 5 indicate protrusions formed by a pair of short pipes welded to the upper surface of the horizontal member 2. The protrusions 5 and 5 are provided at intervals of 400 mm, for example, so that they can be attached to a commercially available pipe scaffold 20 (FIG. 6).

Reference numeral 6 is a standing member made of a metal member having a rectangular cross section that can be loosely fitted in the horizontal member 2. The lower end portion of the standing member 6 is fitted and inserted near the tip of the hypotenuse member 1. It is pivotally supported by a shaft 7. A plurality of stop holes 9a to 9f, through which the hook-shaped stoppers 8 can be inserted, are formed on both side surfaces of the standing member 6 along the longitudinal direction. Then, a rectangular through hole 10 is formed on the upper surface of the horizontal member 2 near the tip end, and the upright member 6 is inserted into the through hole 10, so that the horizontal member 2 is placed on the stopper 8 inserted through the through hole 10. It is configured to support. The structure in which the horizontal member 2 is supported by the stopper 8 is, as shown in FIG. 4, a collar portion 21, 21 of the horizontal member 2.
Comes into contact with the stopper 8 and the horizontal member 2 is maintained in a stable state. In this embodiment, the stopper 8 is formed by processing round steel into an L shape. By the way, the standing member 6
Is arranged substantially along the center line of the hypotenuse member 1, rotates about the support shaft 7 and can be quickly inserted into the through hole 10, and in order to facilitate storage, the upright member. Metal collars (not shown) are fitted on both side support shafts 7 of 6.

Reference numeral 11 denotes a retaining piece that is provided on one side of the horizontal member 2. The retaining piece 11 is a hook-shaped bent piece, and hangs down to the outside of the stopper 8 when the horizontal member 2 is supported on the stopper 8. The stopper piece 11 is provided to prevent the stopper 8 from being pulled out.

On the lower surface of both ends of the hypotenuse member 1,
U-shaped bearing pieces 13 are attached through the hinges 12, respectively,
Further, a pair of support legs 15 and 15 are provided so as to be opened and closed by a support shaft 14 supported by each bearing piece 13. Sign 1
Reference numeral 6 is a cushion material made of sponge rubber, which is attached to the open side surfaces of the supporting legs 15 and 15.

However, in this pedestal for standing up the scaffold, when the support legs 15, 15 arranged at both ends of the hypotenuse member 1 are opened 180 degrees as shown in FIG. 1, the lengths of both support legs become, for example, about 620 mm. The cushion material 16 of 15 and 15 straddles on at least 3 roof tiles adjacent to each other. Here, although not shown, spacers are fixed to the upper surfaces of the two support legs 15 near the support shaft 14, so that the horizontal state of both support legs is ensured when the support legs 15, 15 are deployed. If the four support legs 15 are opened, the rope 17 is hooked on the support shaft 3, and the rope 17 is tied to the balcony or the like on the second floor, the pedestal for standing up the scaffold can be locked on the roof 18 in a safer manner. become. At this time, the large diameter portion 4,
4 functions as a retainer for the rope 17. It should be noted that instead of the large diameter portion 4, the end opening of the horizontal member 2 is used to support the spindle 3
It is also possible to wind a rope directly on the rope and tie the rope tip to a veranda or the like.

Then, according to the inclination angle α of the roof 18, as shown in FIG. 3, one of the stopper holes 9a to 9f is selected and the stopper 8 is inserted therethrough, and the protruding portion of the stopper 8 is inserted. The horizontal member 2 is held horizontally by hooking and supporting the horizontal member 2. There are several types of roof flow gradients defined by Japanese tile roofs, general wooden structures, etc., and the stop holes 9a to 9f are provided corresponding to these various roof gradients. Therefore, if the hypotenuse member 1 is placed on the sloping roof surface and the stopper 8 is inserted into a predetermined stop hole, the horizontal member 2 can be arranged horizontally. 1 and 2, the stopper 8 is inserted into the stopper hole 9b, but in FIGS. 3 and 4, the stopper 8 is inserted into the stopper hole 9a.

When assembling a scaffold on a sloping roof, in a simple way, a plurality of scaffold standing bases are installed side by side on the roof 18, and a scaffold plate 19 is passed over the horizontal member 2 to make the scaffold horizontal. A stable scaffold is completed (Fig. 3). At this time, the protrusions 5 and 5 prevent the scaffolding plate 19 from shifting laterally. on the other hand,
The lower end of the pipe scaffold 20 can be inserted into the projections 5 and 5 to vertically support the entire pipe scaffold 20 as shown in FIG. Therefore, it is possible to build a higher scaffolding on a sloping roof using the scaffolding pedestal as a base. Then, by suspending the rope 7, the scaffolding pedestal ensures a stable and stable scaffolding on the roof.

The scaffold standing base has a structure that can be folded compactly when not in use as shown in FIG. That is, from the state of FIG.
5 and the bearing piece 13 is turned inward by 90 degrees by the hinge 12 so that the supporting legs 15, 15 are provided below the hypotenuse member 1.
And fold the horizontal member 2 in parallel,
The standing member 6 can be pulled out from the above, the stopper 8 can be pulled out, the standing member 6 can be tilted into the hypotenuse member 1, and then the horizontal member 2 can be tilted into the hypotenuse member 1 from above. Then, the horizontal member 2 and the standing member 6 are housed in the hypotenuse member 1, and the main members together with the supporting legs 15 and 15 can be bundled in parallel. Therefore, it is compact and easy to carry and store without being bulky.

In the pedestal for standing up the scaffolding thus constructed, the standing member 6 has a plurality of stop holes 9a to 9f formed therein, and the roof 1
The horizontal member 2 can be always held horizontally by appropriately selecting one of the stop holes 9a to 9f according to the inclination angle of 8 and inserting the stopper 8 therethrough. By setting the interval of the opening of the stop holes 9a to 9f according to the standardized roof slope, the angle can be adjusted more easily. The contractor only needs to have a pair of scaffolding pedestals to build a house with any roof flow gradient. In addition, the commercially available pipe scaffold 20 also has the protrusions 5.
You can easily use it by plugging it in and attaching it. Furthermore, the supporting leg 1
Since 5, 15 are opened 180 degrees so that the cushion material 16 extends over at least three roof tiles, the load is dispersed and the roof tiles can be prevented from cracking. in addition,
The retaining piece 11 projecting from one side of the horizontal member 2 automatically hangs outside the stopper 8 when the horizontal member 2 is supported on the stopper 8, so that the stopper 8 can be removed during use. There is no risk of this occurring, and safety is sufficiently ensured. It is convenient because it can be assembled easily and quickly without using tools. In particular, if the supporting legs 15 are made lighter and the supporting legs 15 are widened, the pedestal for standing up the scaffolding becomes self-supporting on the sloping roof. Therefore, it is not necessary to fix the scaffolding board 19 etc. while supporting the pedestal, and it becomes possible to work alone, and the scaffolding is assembled. Is made easier.

(2) Embodiment 2 In this embodiment, the structure around the stopper 8 is as shown in FIG. The stopper 8 is provided with a disk-shaped retaining collar 81 near one end, and a hole 82 through which a loss-preventing rope is passed is formed at the tip portion. Hole 8
Instead of 2, a pin that can lock the loss prevention rope may be provided. After the stopper 8 is inserted into the predetermined stopper holes 9a to 9f, the standing member 6 is passed through the through hole 10 and the horizontal member 2 is lowered, so that the collar portion 21 of the horizontal member 2 and the standing member 6 are automatically moved. A stopper 81 is sandwiched so that the stopper 8 does not fall off the standing member 6. The pedestal for standing up the scaffolding configured as described above is different from that of the first embodiment in that the retaining piece 1 is provided.
The elimination of 1 reduces the number of parts, and furthermore, since there is no protrusion of the retaining piece 11 during use and storage, there is no danger of catching clothes, which is more preferable. Other configurations, operations, and effects are similar to those of the first embodiment.

The present invention is not limited to those shown in the above embodiment, but can be variously modified within the scope of the present invention depending on the purpose and application. The shape, size, etc. of the hypotenuse member 1, the horizontal member 2, the protrusion 5, the standing member 6, the stopper 8, the retaining piece 11 and the like can be appropriately selected. The number of the stop holes 9a to 9f can be increased or decreased depending on the application.

[0021]

As described above, if the pedestal for standing up a scaffold on a sloping roof of the present invention is used, the scaffold can be assembled easily and quickly even on a sloping surface such as a roof. It is very useful for assembling scaffolds, and when used, it can be folded and made compact so that it has a small storage space and exhibits extremely excellent effects.
