Description

[Detailed explanation of the invention] This invention allows for the use of identically shaped pieces for the left and right pillars without the need to manufacture a symmetrical pair of left and right pillars for each side. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of a scaffold board erection fitting for constructing a scaffold board will be described in detail below with reference to the accompanying drawings showing one embodiment.

A fixture 4 for fixing the support rod 2 to the pillar 3 in a horizontal state is attached to the base and side surfaces of the support rod 2 of the scaffold board 1.

The tip of the reinforcing rod 5 is rotatably connected to the tip of the support rod 2.

Between the middle of this reinforcing rod 5 and the middle of the supporting rod 2, there is a holding rod having a length such that the supporting rod 2 is in a horizontal state when the base end of the reinforcing rod 5 is brought into contact with the column 3 surface. 6 is pivotally mounted on the reinforcing rod 5 side, and the supporting rod 2 side is detachably provided.

The fixing device 4 in the drawing is a common vise type, and 7 is a receiving plate, 8 is a tightening plate, 9 is a tightening bolt, 10 is a rotating bundle, and 11 is a bolt receiving plate.

Reference numeral 12 indicates a locking piece of the scaffolding board 1.

In addition, the reinforcing rod 5 has its tip connected to the supporting rod 2 by the connecting pin 13.
An abutment plate 15 is pivotally attached to the base end by a pivot pin 14.

The holding rod 6 in this figure is pivotally connected to the reinforcing rod 5 by a pivot shaft 16, and a keyhole-shaped locking hole 17 is bored at the end of the supporting rod 2. The locking pins 18 protruding from the sides of the second fixture 4 are engaged with and released from the locking pins 18.

In the conventional scaffold board erection metal fittings disclosed in Japanese Utility Model Application Publication No. 47-27133, the vertical rods 2 and reinforcing joint rods 10 are fixed to the horizontal rods 1, so when installing it on the left and right columns, the tightening metal fittings must be attached from the same direction. There is no problem when installing it over a pillar, but
If there is an obstruction between the pillars such as a wall or a window and it is not possible to install from the inside of the pillar, and if you are installing the fasteners facing each other from the outside, one pillar can be installed from the outside, but the other pillar cannot be installed from the outside. Since the fastening fittings are fitted in the same direction, there is a drawback that they cannot be fitted and attached to the pillar from the inside in the same direction.

Therefore, in order to solve this inconvenience, conventionally it was necessary to prepare two sets, one for the left corner and one for Ishikawa, which was not only inconvenient but also uneconomical.

The present invention solves such drawbacks, and since it is configured as described above, when it is installed on the left and right opposing pillars 3 with an obstacle 19 in the middle as shown in FIG. The reinforcing rod 5 shown in the figure is attached to the outside of one of the pillars 3 via a fixture 4 with the reinforcing rod 5 positioned on the lower side.

Next, when attaching to the column 3 on the opposite side, remove the tip of the retaining rod 6 from the supporting rod 2, rotate the reinforcing rod 5 to the position opposite to the imaginary line shown in FIG. Approximately 90 on the opposite side
After being rotated and attached to the support rod 2, the entire island is turned over to the opposite side and attached to the outside of the column 3 via the fixture 4.

Therefore, even if there is an obstacle 19 between the columns 3, the reinforcing rods 5 can be installed in different positions, and the fixing members 4 can be attached to the outside of the columns 3 facing each other by turning the proposed product upside down and using it. I can do it.

Furthermore, the holding rod 6 can be removed and the holding rod 6 and the reinforcing rod 5 can be rotated and folded, which makes it more compact and convenient for storage and portability.

As described above, according to the present invention, there is no need to manufacture a pair of left-right symmetrical ones separately, and the same shape can be used.In addition to being able to manufacture them at a lower cost, it also has advantages such as being able to easily erect scaffolding boards. Therefore, the present invention provides a scaffolding board erection metal fitting that exhibits practical effects.
