Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing member for a construction scaffolding device.

During the construction of general residential buildings, construction work on tilted roofs, especially at the eaves, is extremely dangerous work.

Structures such as shrines and temples are relatively large and their construction is complicated.
Temporary construction work is carried out to prevent danger in workplaces that require many years of work, but most of the construction works for general residential construction are carried out by on-site workers who have extensive work experience, and falling accidents are common. The reality is that there are no facilities of any kind.

Therefore, many falls have occurred while working under eaves, and the Labor Standards Act requires the use of a lifeline when working on roofs to prevent such accidents.

However, at present, it is rarely used because its use significantly reduces work efficiency.

The present invention was invented in view of the above points, and in particular, in the event of an accidental fall from the eaves when working on a roof, it is possible to catch the fall by contacting the eaves and prevent the fall to the lowest floor. The purpose of this invention is to provide a sturdy safety scaffolding device that can be easily attached and detached and can also be used as a scaffold for work under the eaves, while also minimizing personal accidents.

In addition, at construction sites where manual labor is the main activity, it is very reassuring for workers to have scaffolding in place to catch them in the unlikely event of a fall, and their work efficiency is also significantly improved. It is also expected to have an improved psychological effect.

Hereinafter, one embodiment of the present invention will be described in detail based on the drawings.

FIG. 1 shows the implementation state, in which a fixing member 3 is fixed to a pillar 2 that holds a roof 1, a beam 4 is held to this fixing member 3, and a support 5 is attached to the tip of this beam 4. 1 with some gap from the bottom end.

The beams 4 and columns 5 are attached to a plurality of columns 2... via the fixing members 3 on the roof 1 corresponding to the workplace, and the beams 4
. . . Scaffolding timber 6 . . . is erected to form a scaffold, and timber 8 is erected on the receiving member 7 .
... to catch workers who fall from the roof.

As shown in FIGS. 2 to 5, the fixing member 3 is made up of ribs 9, 9, which have a cross-section shaped like an ellipse, and are in contact with both side surfaces of the column 2. A beam holder 11, which is provided with plates 10, 10 and through which the beam 4 is inserted at an intermediate position;
11, and furthermore, pipe portions 12.12 are formed at the upper and lower positions of one of the slats 9 (the left slat in FIG. 2), and pipe portions 12.12 are formed at the upper and lower positions of one of the slats 9 (the right side of the slat in FIG. 2). Threaded portions 13 and 13 are formed at the upper and lower positions, respectively.

are evenly tightened through the washers 24 and 24 so that the beam supports 11 face each other in a straight line, the retaining plate 22 is pressed against the back surface of the column 2, and the L-shaped retaining plates 9, 9 and the retaining plate 22 are pulled. By attaching the brackets 9, 9, which are fixed to the pillar 2 in an interlocking manner.
This prevents the beam 4 from falling off and facilitates the insertion and insertion of the beam 4.

That is, when an external force is applied to the scaffold and the pillar 5, and a downward load is applied to the beam 4, a force is applied to the support plates 9, 9 in a direction in which they are removed from the pillar 2.

In other words, the center of gravity of the force support is at the center of the part of the support plate 9 that is in pressure contact with the column 2, and depending on the distance between this point and the beam 4,
A rotational moment acts on the retaining plate 99 in the directions of arrows A and A shown in FIG. Plate 9,
Since the beams 9 and 9 are attracted to each other, this rotation and bending can be prevented to prevent the beams 4 from falling off the pillars 2 and to facilitate the insertion of the beams 4.
