The side surface is provided with a connecting member 6 having a fan-shaped portion 5 at the tip, and the fan-shaped portion 5 of the connecting member 6 is provided with a plurality of through holes 7 on a concentric circle centered on the O point. It will be drilled. Reference numeral 8 denotes a rectangular plate provided between the upper surfaces of the side pieces 4 of the fixing member 1, and a so-called single clamp 10 to which a pipe 9 can be externally fitted as shown in FIG.

Reference numeral 11 denotes a bracket main body having a U-shaped cross section. One end of the bracket main body 11 is rotatably connected to the other end of the fixing member 1 through a truncated numeral 12, and A plurality of through-holes 14 that can communicate with the through-hole 7 of the connecting member 6 are formed at one end of the side piece 13 and a lock inserted through the through-hole 14 and the through-hole 7 of the connecting member 6. A nut 16 is fastened to the bolt 15 as a means, and a single clamp 18 to which the pipe 9 can be externally fitted as shown in FIG. And the nut 20.

Reference numeral 21 denotes a horizontal plate 26 which is slidably attached to a long hole 23 formed in the bottom surface 22 of the bracket body 11 by means of bolts 24 and nuts 25, a hanging plate 27 hanging down at one end of the horizontal plate 26, An elongate hole 28 is drilled in the vertical direction, and an L-shaped elevating member 31 slidably attached to a hanging plate 27 by bolts 29 and nuts 30, and a side plate provided on an L-shaped main body 32
33 is a reinforcing bracket consisting of a rotating member 36 rotatably attached to the lower end side surface of the elevating member 31 with a bolt 34 and a nut 35, and a pair of nuts 37 arranged on both sides of one piece 36a of the rotating member 36 Is screwed with a screw rod 38, and an engagement plate 39 is fixed to an end of the screw rod 38.

The present embodiment is constructed as described above. Next, a case where the membrane material 41 is stretched on the skeleton 40 of the membrane structure using the above structure will be described.

In this case, as shown in FIGS. 3 and 4, a membrane mounting plate 42 constituting the top of the skeleton 40 is used as a scaffolding structure, and for example, a pair of scaffold brackets A is attached to the membrane mounting plate 42. Attach with a predetermined interval. That is, of the bolts 43 arranged in two rows on the upper surface of the membrane mounting plate 42, a predetermined bolt 43 located on the upper side is inserted into the through hole 3 of the fixing member 1, and a nut 44 is fastened to this. And fix it.

Thus, by using the membrane mounting plate 42 as a scaffold structure and attaching the fixing member 1 to the bolt 43, it is not necessary to prepare a separate scaffold structure. This has the advantage that the operation can be greatly simplified.

Thereafter, the bolts 15 are removed from the through holes 7 of the bracket body 11 and the through holes 14 of the connecting member 6 so as to arrange the bracket body 11 substantially horizontally, and after the bracket body 11 is appropriately rotated, The nuts 16 are tightened by inserting the bolts 15 again into the two through holes 7 and 14 so as to coincide with each other.

Further, the elevating members 31 of the reinforcing bracket 21,
The rotating member 36 and the screw rod 38 are appropriately adjusted so that the other piece 36b of the rotating member 36 is engaged with the wooden truss 45 of the skeleton 40 as shown in FIG. 40 columns 46
And hold it. As a result, the scaffold bracket A can be fixed in a stable state.

Next, the scaffold plate 46 is erected between the bracket bodies 11 of the scaffolding bracket A, and the pipes 9 are erected and attached to the individual clamps 10, 18 of the scaffolding bracket A. In this case, if the orthogonal clamp 47 is attached to the rear pipe 9 and a handrail 48 is provided on the orthogonal clamp 47, it can be provided for convenience of work.

This completes the scaffold assembling work.
Since the scaffolding bracket A itself is substantially rod-shaped and ready to be handled, a series of assembling operations can be performed easily and quickly.

When the membrane material 41 is to be stretched on the frame 40, first, an operator rides on the scaffold plate 49 and uses the pipe 9 on the front side to jack the membrane material 41 with the membrane mounting plate 42. Side, and bolts 43 located below the membrane mounting plate 42 are inserted into mounting holes (not shown) formed in the ends of the membrane material 41 and sequentially fixed with fasteners 50. I should go.

Even in the case where the angle of inclination of the frame 40 is different as shown in FIG. 5, the bracket body 11 is substantially rotated by rotating the bracket body 11 and adjusting the angle as described above. The bracket main body 11 can be arranged horizontally, and the reinforcing bracket 21 is also adjusted by adjusting the respective members such as the elevating member 31, the rotating member 36 and the screw rod 38.
It is possible to engage with the skeleton 40 according to the rotation of,
When the screw rod 38 is unnecessary, it may be detached from the turning member 36 as shown in the figure, and the turning member 36 may be directly engaged with the frame 40.

After the extension of the lower membrane member 41 is completed, the upper membrane member 41 is extended. In this case as well, a plurality of bolts 43 on the lower side of the membrane mounting plate 42 are attached. The work may be performed by fixing the scaffolding bracket A, and laying the pipe 9 between the scaffolding brackets A. However, in this case, since it is possible to work on the film material 41 on the lower side, the scaffold plate 49 is unnecessary.

In the above embodiment, the case where the membrane material 41 is stretched on the skeleton 40 of the membrane structure has been described. However, the scaffold bracket A according to the present invention is not limited to this. However, it can be widely applied to other construction sites.

Further, the plurality of through holes 7, 14 formed in the connecting member 6 of the fixing member 1 and the bracket body 11, respectively, can be changed to arc-shaped long holes. The locking means for fixing at a predetermined rotation angle is not limited to the above embodiment.

Further, the pipe 9 and the reinforcing bracket 21 may be provided as appropriate according to the intended use or purpose, and need not necessarily be provided.

The specific configuration of the other parts can be arbitrarily changed within the range intended by the present invention.

[0026]

As described above, the present invention is configured so that the angle of the bracket body on which the scaffolding plate is erected can be adjusted with respect to the fixing member, so that the fixing member to the frame in the membrane structure can be adjusted. It is possible to arrange the bracket body almost horizontally regardless of the mounting angle, so that the applicable range is greatly expanded and the height is increased compared to the conventional one where the angle of the bracket body could not be adjusted. The special effect that work in a place can be done safely has been attained. In addition,
The scaffolding bracket according to Ming is used as a framework for membrane structures.
Since it is to be attached, for example, the film material 41 is stretched
It is not necessary to prepare a scaffold structure
There is an advantage that the simplification of the above can be greatly simplified.

Further, since the scaffold bracket according to the present invention has a very simple structure, there is an effect that the scaffold can be manufactured easily and at low cost.
