2. Description of the Related Art A conventional locking tool for temporary scaffolding of this type is one in which a hook portion is provided on a clamp, and this clamp is used for a pillar pipe of a temporary scaffolding or a temporary pipe for horizontal installation. It was hugged and fixed to, and the hook part was hooked with, for example, a seat hamlet or a net which was hung and stretched outside the temporary scaffold.

However, the temporary scaffolding is constructed by inserting (inserting) and locking the wedges at the tips of the temporary pipes that are cross-arranged in the locking holes and pockets of the connecting plate provided around the columns. Despite the fact that the work is done in high places and does not require complicated tightening work, work to tighten the clamp is necessary to provide a hook for hanging this seat or net. The current situation is that it has ended.

In view of the above situation, the present invention utilizes a locking hole for locking a wedge or a locking pocket to lock a locking tool having a hook portion, such as a clamp. An epoch-making temporary structure that requires no work and allows hooks to be installed on temporary scaffolds by inserting and locking them into existing locking holes and pockets from above, similar to wedges for building scaffolding. An object of the present invention is to provide a seat or net locking structure using a scaffold locking tool.

[0013]

Embodiments of the present invention will be described with reference to the drawings.

In this embodiment, the hook portion 1 is provided so as to project from one side of the base body 2 and the insertion locking fixing portion 7 is provided so as to extend vertically to the opposite side. Specifically, it is made of a plate material. The hanging portion 2A is provided on one side of the base body 2 and the lower portion of the hanging portion 2A is bent into a bifurcated shape to bend the hook portion 1A.
Is integrally formed, and the hanging bent portion 2 is provided on the opposite side of the base body 2.
In parallel with A (although it is not parallel)
B is provided, both edges of the opposite side hanging bent portion 2B are bent to form a predetermined shape, and the opposite side hanging bent portion 2B is formed on the pillar 3
The insertion locking fixing portion 7 which is inserted (striking press-fitting) and locked from above is integrally formed in the locking hole 6 or the locking pocket 6'provided around the circumference.

In the first embodiment shown in FIGS. 1 to 5, one of the locking holes 6 formed at four radial positions of the connecting plate 8 provided around the pillar 3 (column pipe) of the temporary scaffold A. to, the interpolation
Input engagement fixing portion 7 is configured to be inserted locking.

Further, in a state in which the insertion locking fixing portion 7 is inserted and locked in the locking hole 6, the base body 2 is disposed on the connecting plate 8 in a superposed state, and the hanging portion provided with the hook portion 1 is provided. Curve part 2A
Is configured to be in contact with the outer edge of the connecting plate 8 or to hang down outside the outer edge.

Further, in this embodiment, the grounding protrusion 9 is formed so as to be bent and suspended so that the base 2 is grounded on the connecting plate 8 with good stability.

Further, in the second embodiment shown in FIGS. 6 and 7,
One end is joined to the base body 2 and the hanging end at the opposite end is bent inward to provide a reinforcing plate 10 that abuts or comes close to the support column 3, and the insertion locking fixing portion 7 of the base body 2 is set in the locking hole 6. It is configured so that the inserted and locked posture is maintained. That is, the posture in the attached state does not change due to external force applied, and the locking hole 6 causes the wedge 5 to move.
Does not come off easily.

Further, in the third embodiment shown in FIGS. 8 and 9,
The insertion locking fixing portion 7 is inserted (striking press-fitting) into a locking pocket portion 6'provided on the outer circumference of the support column 3 and locked.

[0020]

Since the present invention is constructed as described above, a locking device having a hook portion by using a locking hole for locking a wedge and a pocket for locking is similar to the conventional clamp. It is a epoch-making that the hook part can be installed on the temporary scaffold by inserting and locking from the upper side into the existing locking hole and pocket part like the wedge for constructing the temporary scaffolding, without requiring any clamping and holding work. Of seats or nets using traditional temporary scaffolding fasteners
It becomes a stop structure .

Particularly, in the inventions according to claims 3 and 4,
Easy seating , excellent mass productivity, low manufacturing cost, and extremely practical seats with temporary scaffolding fasteners
It has a net locking structure .
