Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a hanging metal fitting for grating used when, for example, a scaffolding chain is suspended from the installed grating at a construction site. .

(Prior art and its problems) In the hanging metal for grating, a hanging ring having a length that penetrates through the gap of the grating and projects downward is provided at the center of a plate that can be placed on the grating. In the conventional hanging hardware of this type, the upper end of the hanging ring is welded and fixed to the plate body.

In such a conventional hanging hardware, the whole is T-shaped and is very bulky, so that the occupied space during transportation and storage is large, and the cost for transportation and storage is high. Further, when a lateral force is applied to a scaffolding chain or the like suspended from the suspension ring, there is a risk that stress concentrates on the welded portion of the suspension ring and the suspension ring is broken.

(Means for Solving the Problems) In order to solve the above conventional problems, the present invention provides
In the central part of the plate that can be placed on the grating, a hanging ring having a length that penetrates through the gap of the grating and projects downward is swingably suspended, and half of the plate is An object of the present invention is to propose a grating hanging metal article which is configured to be changeable between a folding position overlapping the hanging ring and a T-shaped using position with respect to the hanging ring.

(Embodiment) An embodiment of the present invention will be described below with reference to the attached exemplary drawings.

In FIGS. 1 to 4, reference numeral 1 denotes a rectangular plate body having a size capable of being stably placed on a grating, and a central position in the long side direction thereof has a short side direction. Longitudinal section U parallel to
A V-shaped recessed groove 2 is formed by bending the plate body 1, and two through holes 3 and 4 are formed in the recessed groove 2. Reference numeral 5 denotes a hanging ring, which is obtained by inserting both ends of a U-shaped curved wire into the through holes 3 and 4 from below and then bending both ends of the wire inward to form a butt end 6 thereof. Are welded to each other to form an endless shape, and the linear portion 7 at the upper end is loosely fitted in the recessed groove 2 between the through holes 3 and 4.

However, the two through holes 3, through which the hanging ring 5 passes,
4 is formed so as to curve in a U-shape from one end of the U-shaped side wall of the recessed groove 2 to the other end. Therefore, the hanging ring 5 uses the linear portion 7 at the upper end as a fulcrum. And can swing in the long side direction of the plate body 1, and as shown in FIG.
It is possible to adopt a folding posture in which half of the above is overlapped with the hanging ring 5.

When the hanging hardware 8 configured as described above is used,
As shown in FIG. 6, when the plate 1 is in a T-shape with respect to the hanging ring 5, the hanging ring 5 faces downward into the gap 11 between the lattice plates 10 of the grating 9. , The plate 1 is placed on the plurality of grid plates 10, and the hanging ring 5 is projected downward from the gap 11. In this state, the chain 12 for suspending the work scaffolding frame, the safety net stretching frame and the like is hung from the hanging ring 5. At this time, since the hanging ring 5 can swing with respect to the plate body 1 with the linear portion 7 as a fulcrum,
Within the range of the gap 11 between the chains 10, the chain 12 can be swung by a tensile force acting on the chain 12.

It should be noted that, when the hanging hardware 8 is transported and stored, the occupied space can be made smaller by making it the folding posture shown in FIG. 5, but by making the hanging metal fitting 8 the folding posture shown in FIG. The plate body 1 and the hanging ring 5 are inserted into the gaps 11 between the lattice plates 10 from below, and the plate body 1 protruding above the space between the lattice plates 10 is formed into a T-shape with respect to the hanging ring 5. It is also possible to set the hanging metal fitting 8 in the state shown in FIG. 6 by lowering the hanging ring 5 after turning it down. That is, the hanging hardware 8 is a grating 9
It is also possible to set from below.

(Operation and effect of the invention) As described above, according to the hanging hardware for grating of the present invention, the folded space in which half of the plate overlaps the hanging ring reduces the space required for transportation and storage, The cost required for transportation and storage can be reduced.
Also, in use, the suspension ring can be swung in the direction of the force acting on the suspension chain,
Unnecessary stress concentration can be avoided and safety can be improved.

Furthermore, depending on the case, it is possible to set from the lower side of the grating by utilizing the folded posture.
