Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to a fixture for fixing a suspended scaffold.

[Conventional technology]

As shown in FIG.
There is a suspended scaffold 21 which is provided in parallel with the scaffold board 21b, a handrail frame 21c, and a handrail post 21d, which are rotatably assembled, and which can be folded as a whole.

The hanging scaffold 21 is of a hanger type and is attached to the upper flange of the beam steel frame via fixing fittings.

FIG. 6 is a perspective view showing a conventional example of this fixing fitting 22, in which one end is connected to a support column 21a behind the suspended scaffold 21.
It is composed of a support rod 23 that is pivoted to the support rod 23 and a locking pawl 24 that can freely move forward and backward with respect to the support rod 23. 24a, and the support rod 23 has a threaded portion formed on its peripheral surface, into which a nut 25 is screwed.

In this way, the nut 25 is rotated, and when it moves forward, the locking pawl 24 is also pushed forward,
The upper flange of the beam steel frame is sandwiched between the connecting portion of the support column 21a to the support rod 23 and the locking claw 24 from the front and back.

[Problem that the invention attempts to solve]

By the way, as shown in the figure, in such a conventional fixture 22, the tip of the support rod 23 is fixed to the suspended scaffolding 21 with a bolt, and can only be rotated in the vertical direction. Therefore, if only diagonal connection is possible, such as at a corner, the suspended scaffolding 21 cannot be attached.

In order to eliminate this drawback, it is possible to combine a member that moves only in the horizontal direction and a member that moves in the vertical direction and provide two shaft attachment parts.
This not only complicates the structure, but also increases the number of weak points in terms of strength, such as shaft attachment parts, leaving instability.

The purpose of the present invention is to eliminate the disadvantages of the conventional example,
To provide a fixing fitting for a suspended scaffold that is rotatable not only in the vertical direction but also in the horizontal direction, improving usability, and requiring only one shaft attachment part and a small number of members.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a fixing fixture consisting of a support rod that is connected at one end to the back of a suspended scaffold and has a locking claw that can move forward and backward in the middle. Then, a support part is provided on the back of the support column on the scaffold side, in which a T-shaped long hole is formed in the front surface, and a long hole is formed in the bottom plate from the front end to the center, with the end of the long hole communicating. A pull-out prevention body having a circular cross-sectional shape is provided at the end of the support rod, the pull-out prevention body is housed in the support part, and the other part of the support rod is movably projected from the elongated hole along this. The main points are as follows.

[Effect]

According to the present invention, the support rod moves along the T-shaped long hole and rotates both vertically and horizontally. Moreover, the connection between the support part on the scaffold side and the support rod is
Only one location is required via the circular enlarged end.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

Fig. 1 is a plan view showing an embodiment of the fixing fitting for a suspended scaffold according to the present invention, and Fig. 2 is a side view of the same.
1 shows a support column of a suspended scaffold, and in the figure, 1 is a support rod and 2 is a locking claw.

The fixing fitting of the present invention also consists of a support rod 1 having a locking claw 2, this locking claw 2 is provided with a tube body 3 that slides on the rod 1, and the support rod 1 is formed with a threaded portion 1a. , in that the wing nut 4 is screwed here, similar to the conventional one shown in FIG. 6. In the figure, 5
indicates a pin to prevent extraction.

In the present invention, a pull-out prevention body 6 having a circular cross-sectional shape is provided at the base end of the support rod 1, and a support portion 8 having an arcuate front surface is provided protruding from the support column 21a of the scaffold using a bolt 7 or the like.

FIG. 3 is a front view of this support part 8, and FIG. 4 is a bottom view of the same as above, in which a T-shaped elongated hole 9 is formed in the center of the circular arc-shaped front surface, the bottom part is closed with a bottom plate 11, and this bottom plate A long hole 10 is formed in 11 from the front end toward the center, through which the vertical ends of the long hole 9 communicate.

On the other hand, the pull-out prevention body 6 of the support rod 1 is housed within this support portion 8. The ampullae may be spherical, but
As shown in the figure, using the circular short tube 6a, the support rod 1
This can be easily obtained by inserting the root end of the tube into the support part 8 from the outside through the elongated hole 9, and fixing it by welding with the side wall of the short tube 6a interposed.

In this way, the pull-out prevention body 6 of the support rod 1 is housed in the support portion 8, and the other portion of the support rod 1 protrudes from the support portion 8 so as to be movable along the elongated hole 9. do.

Next, how to use it will be described. The support rod 1 moves within the elongated hole 9, and the connection angle to the scaffold can be adjusted not only in the vertical direction but also in the horizontal direction. Furthermore, if the object moved downward is further inserted into the elongated hole 10 of the bottom plate 11, the support rod 1a can be made parallel to the support column 21a of the scaffold as shown in FIG. 5, and when the scaffold is folded and stored. It doesn't need to stand out.

Note that this is the same as the conventional method in that the wing nut 4 is moved back and forth on the threaded portion 1a of the support rod 1 to move the locking pawl 2 forward and backward, thereby attaching it to the upper flange of the beam steel frame.

[Effect of idea]

As mentioned above, the fixing bracket of the suspended scaffold of the present invention can be rotated not only vertically but also horizontally, so when setting the suspended scaffold in a corner etc., the fixing bracket can be tilted diagonally, improving usability. It is something to do.

In addition, since the structure that can be rotated in all directions requires only one shaft attachment part and the number of parts is small, it can be easily and inexpensively manufactured without causing a decrease in strength.
