Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention 1] The present invention relates to a scaffolding support that can be attached to or removed from a scaffolding frame with one touch.

I'm confused! U Old 1 Conventional building frame supports were fixed to the scaffolding frame with clamps, and were straight.

Therefore, tools such as ratchet spanners must be used when attaching or removing them, which not only makes the work troublesome and time-consuming, but also prevents the upper part from attaching to the top unless the support is removed. It is not possible to add another building frame, or conversely, if there is a building frame on top, it cannot be attached, making it dangerous to attach ropes and handrails during scaffolding assembly and dismantling work. It was something. Additionally, conventional building frame supports had drawbacks such as being heavy and having poor workability.

The present invention has been made in order to eliminate the drawbacks of the conventional building frame supports, and its purpose is to allow easy and quick installation and removal without the need for any tools. To provide a support for a building frame that is light and durable, can be kept attached at all times during all the work of assembling and dismantling scaffolding, and not only allows the work to be carried out safely.

゛ [Structure of the invention] L! ]'Means for relieving/fixing the T point The building frame support of the present invention has two steady rest pieces arranged in a vertically shifted manner in the lower part of the attachment part, and formed in an arc shape and facing each other. The device is characterized in that a gripping member is provided at the upper end of the mounting portion and a support portion is extended upwardly, and the mounting is appropriately carried out above the mounting portion having a means. The support is characterized by an extended support, whose lower part is bent so that its axis is offset from the extended axis of the attachment part, and a master rope or handrail tightening part is provided at its upper end. It is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a support such as an MG4 support, which is composed of a mounting portion 1a and a support portion 1b. A lower steady rest piece 2 and an upper steady rest piece 3 are planted in the lower part of the mounting portion 1a. These steadying pieces 2 and 3 have an arcuate shape, are arranged facing each other, and are adapted to hold the building frame pipe from the left and right sides. Note that the above-mentioned arcuate shape includes shapes such as molds, and the steady-stop pieces 2 and 3 may be plates.

A support plate 4 is attached to the upper end of the attachment part 1a, and a grip plate 5, which is open at the bottom, is attached at right angles to the tip of the support plate 4. Note that the support plate 4 and the grip plate 5 may be formed integrally by bending a single plate, as long as they can surround the upper end of the vertical pipe and grip the horizontal pipe from above. As is clear from FIG. 2, an arc-shaped slot 7) 5a is bored in the gripping plate 5, and the lock claw 6 for preventing floating is rotated using this as a guide to close the opening. It is designed to open.

A strut portion 1b is extended above the mounting portion 1a, and the lower portion of the strut portion 1b is bent so that the axis of the strut portion 1b is deviated from the thin extension line of the mounting portion 1a.

The upper end of the support column 1b is folded back into an annular shape to form a tightening section 7, around which the main rope is wound or tied. The lower part of the tightening part 7 is open, and a stopper 7a is attached to the lower part thereof in a slightly upward direction to prevent the tightened main rope from coming off. Note that the tightening section 7 is not limited to this, and may be of the type shown in FIG. 3.

Further, the upper ya part of the support column 1b is not only used for tightening the main rope as described above, but also may be provided with a handrail.

Since the column of this example is constructed as described above, when attaching it to the scaffolding frame F, first tjS
As shown in Figure AA, tilt the support 1 and attach the double-folding stoppers 2 and 3.
The outer pipe f2 of the building frame F is sandwiched between the two sides. In this case, either one of the steady stop pieces 2゜3 is connected to the pipe f! You can set it stably by leaving it latched on.

Next, the support column 1 is raised straight as shown in FIG. , and then push down the pillar 1 along the bi-7go 1.

When the strut 1 is pushed down, the gripping plate 5 fits into the horizontal bi-7go 2, and as a result, the strut 1 is moved between the steady rest pieces 2, 3 and the gripping plates 5, 3. It is firmly fixed to the building frame F by α. (!
(Refer to figure m4C) When fitting the above-mentioned gripping plate 5, pull up the lock claw 6 attached to it with your fingers in advance as shown in the imaginary line, and once it is fitted, lift it by its own weight or as shown in the solid line. Close the opening by pulling it down with your fingers or the like to prevent the support post 1 from coming off due to some force.

When the installation of the strut 1 is completed as described above, the master rope #lR is inserted through the gap between it and the stopper 7a, and the master rope Rf is wound or tied around the tightening part 7 formed at the upper end of the strut part 1b.

In addition, in order to remove the above-mentioned main rope support 1 from the building frame F, the above-mentioned operation may be performed in reverse.

In the above embodiment, the one-touch installation method is described as a building frame support that integrally comprises the mounting portion 1a and the bent and biased support portion 113. However, the present invention is not limited to this, and the one-touch installation method is A combination of the mounting portion 1a and a straight support portion, or a conventional mounting using a clamp or the like may be used, or a combination of a mounting portion having a means and the bent support portion 1b may be used.

[Effects of the Invention] (1) Two steady rest pieces are arranged in a vertically shifted manner in the lower part of the mounting part, and are formed in an arc shape and planted facing each other, and the upper end of the mounting part Since a gripping member is provided on the part, it can be attached reliably and firmly with a one-touch operation without using any tools.

(The pillar part is extended above the second mounting part, and the lower part of the pillar part is bent to deviate its axis from the extended axis of the mounting part, so the uppermost building frame to which the pillar is attached is You can add another building frame on top of it, or conversely, attach the support to an intermediate building frame and remove the upper building frame. can be attached and work can be done safely.

(3) Light and durable, it is easy to work with and can be used repeatedly.
