Description

[Detailed Description of the Invention] The present invention relates to a scaffolding board support bar that is attached from an H-shaped steel pipe onto a certain strut to support a scaffolding board, and the scaffolding board support bar is equipped with means for fixing to the said strut. It provides a bar for use.

One embodiment will be described below based on the attached illustrative drawings. In FIGS. 1 and 2, 1 is a scaffold board support bar, 2 is a pipe clamp fixed to one end of the bar, and 3 is a bar made of H-beam steel. 4 is a fastening means provided on the scaffolding board support bar 1; 5 is a handrail support secured by a pipe clamp 2;

As shown in FIGS. 3 and 4, the scaffold board supporting bar 1 is made of two C-shaped steels 7 arranged in parallel with openings 6 facing each other, and the fastening means 4 is a clamping member. Piece 8 and portal member 9,
and a fixing bolt} 10.

The supporting piece 8 is provided at one end with a protrusion 11 that is loosely fitted from below between the C-shaped steels 7 so as not to rotate.

This protruding portion 11 has a female screw body 12 through which the screw hole passes vertically.
and two side plates 13 sandwiching this female threaded body 12.

The gate-shaped member 9 has both C-shaped steels 7 so that its side plate portions 14 fit into the lower inner recesses 15 of the C-shaped steels 7 through the openings 6 of the C-shaped steels 7.
10 is a gate-shaped member 9
It penetrates the top plate 16 downward and is screwed into the female screw body 12 in the protrusion 11 of the supporting piece 8, and its head 17 is connected to the top plate 1.
6 and in an upper space 18 between both C-shaped steels 7, and can be rotated from above through the upper space 18.

As shown in FIGS. 1 and 2, two of the above-mentioned fastening means 4 are provided in the length direction of the scaffold board support bar 1, and both of them are configured as described above. The supporting pieces 8 are arranged in opposite directions so as to face each other.

When attaching the scaffolding board support bar 1 to the strut 3, place the scaffolding board support bar 1 on the strut 3 so that the strut 3 is located between the two fastening means 4, and then attach the clamping pieces 8. Both the C-beams 7 are slid along the guide along with the fixing bolt 10 and the portal member 9 toward the strut 3, and the supporting piece 8 is inserted under the flange 3a of the strut 3.

The clamping piece 8 can also be slid from above the scaffold board support bar 1 using a rotary operation tool such as a box spanner fitted onto the bolt head 17 from above.

Next, the supporting piece 8 is pulled up by rotating the bolt 10 with a box spanner or the like fitted into the head 17 of the bolt 10 from above.
By supporting the 7 flange 3a between the clamping piece 8 and the C-shaped steel 7, the installation work is completed.

The scaffold board is placed on the scaffold board support bar 1, and the scaffold is constructed from a handrail post 5 fixed to a pipe clamp 2, a handrail pipe, etc. supported by the post 5.

The scaffold board support bar with fastening means of the present invention can be implemented as described above, and the scaffold board support bar can be easily and easily fastened to the struts. The support bar is constructed from two parallel C-shaped steels, and both C
The fixing bolts that raise and lower the supporting pieces can be rotated from the upper space between the form steels, which not only increases the strength of the scaffold board support bar itself, but also makes it easier to insert your hand between the upper and lower flanges of the struts. Conventional products (Jikko 52-1
546 etc.), it is much easier to lock and release the lock.
