Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a movable suspension used for coating a roof, wall, etc. of a building with a metal plate.

(Prior Art) Conventionally, as a rotary suspension of this kind, as disclosed in Japanese Utility Model Publication No. 57-125823, Japanese Utility Model Publication No. 60-122432 and Japanese Utility Model Publication No. 62-144322. Various structures are known.

In each of these conventionally known movable suspensions, a tongue is slidably attached to one side in the width direction of the board in the length direction, and the tongue piece is attached to the tongue on the other side off the center of the board in the width direction. An anchor is driven into the structure through a mounting hole formed in the base plate on one side of the piece to fix the base plate to the structure, and the cover metal plate is attached to the tongue piece by seam welding.

(Problems to be solved by the invention) However, in the conventional structure as described above, there is a problem that the tongue piece is crushed when the anchor is driven and fatigue fracture occurs, and the substrate is deviated from the center in the width direction. Since it is fixed by the anchors at different positions, the substrate is easily bent and deformed, and as a result, it is difficult to slide the tongue piece.

The object of the present invention is to provide an improved movable suspension which eliminates the above-mentioned problems.

(Means for Solving the Problems) As shown in the drawings, the present invention provides a movable suspension including a substrate 1 and an upright tongue 2 slidably mounted on the substrate, in which the substrate 1 is An upright tongue having a central recess 3 extending along the lengthwise axis, guide rail portions 4 extending parallel to both sides of the recess, and a mounting hole 5 formed approximately at the center of the central recess in the longitudinal direction. The piece 2 is provided at the center of the sliding plate 6, and the sliding plate 6 has bent engaging portions 7 at both ends for slidably engaging the guide rail portions 4, respectively. It is characterized in that the bent engaging portions 7 at both ends are engaged with the guide rail portion 4 so as to be slidably mounted on the substrate 1 over the width direction.

In carrying out the present invention, it is preferable to taper both ends 2a, 2b of the upright tongue 2 in the longitudinal direction.

(Operation) According to the present invention, after the substrate 1 is fixed to the structure by the anchor, the sliding plate 6 to which the upright tongue 2 is attached is attached, for example,
Immediately before the covering metal plate is laid, it can be attached at a predetermined position by inserting it onto the substrate 1 from one end in the length direction and sliding it in the length direction.

As described above, the tongue piece having the post-attachment structure can prevent the tongue piece from being crushed without taking any special protection measures. Eliminates the load bias and eliminates accidental breakage.

Further, as described above, since the tongue piece has the retrofitting structure, the center of the substrate 1 can be fixed by the anchor, and the tongue piece 2 can be slidably attached on the same line as the anchor. Since there is no eccentricity of the driving anchor, bending deformation is unlikely to occur, therefore the sliding distance of the tongue can be increased and the sliding function of the tongue is not impaired until a predetermined proof stress is reached, and therefore the heat of the coated metal plate is reduced. It is possible to prevent the tongue from sliding due to the horizontal load caused by the expansion and contraction, and thus breaking the tongue.

Further, by tapering both ends in the length direction of the tongue, the weldability between the coated metal plate and the tongue is improved, seam welding is smoothly performed, and welding defects can be eliminated.

(Embodiment) One embodiment of the present invention is shown in FIG. 1, and in the illustrated example, a substrate 1 having a thickness of 2 mm is provided with a central concave portion 3 extending in the longitudinal direction thereof and parallel to both sides of the central concave portion 3. And a guide rail portion 4 extending to the base plate 1, so that the substrate 1 has the same cross-sectional shape over the entire length. The tongue piece 2 is a 0.3 mm thin plate with a thickness of 2 mm
The sliding plate 6 is projected through a groove hole 8 formed in the center of the sliding plate 6, and both ends of the sliding plate 6 in the width direction are bent to form an engaging portion 7.

While fixing the substrate 1 to the structure 10 by driving the anchor 9 through the mounting hole 5 at approximately the center of the central recessed portion 3 of the substrate 1, the bending engaging portions 7 at both ends of the sliding plate 6 are fixed. The sliding plate 6 is inserted into the guide rails 4 on both sides of the board 1 to form the board 1
It is configured so that it can be slid in the length direction of the substrate 1 while being straddled in the width direction.

Both ends 2a, 2b of the tongue 2 are tapered.

(Effects of the Invention) According to the present invention, the problem that the tongue is crushed when mounting the board is eliminated, the occurrence of an accident due to the breaking of the tongue under a predetermined stress or less is prevented, and the tongue of the tongue is prevented from bending due to bending deformation of the board. It is also possible to prevent breakage due to poor sliding, and it is possible to significantly improve the reliability and durability of the structure for attaching the covered metal plate to a structure such as a roof or a side wall.
