Description

[Detailed Description of the Invention] This invention relates to, for example, a connecting fitting for a bar to which a ceiling plate is attached.

When connecting the ends of the horizontal bars in a planar T-shape or cross shape to the vertical bars on which the ceiling panels are attached, first insert the insertion piece of the connection fitting into the end of the horizontal bars, and then attach the above to the upper edge of the side wall of the vertical bars. The hook pieces of the connecting fittings are overlapped to receive the rack, and the protrusions on both sides sandwiching the hook pieces are bent by a tool and hug the upper edge of the side wall to prevent the ends of the row bars from lifting up and falling off. It is necessary to bend each protruding piece of each connecting fitting using a tool.

For this reason, it is time-consuming and work efficiency is significantly reduced.

This invention aims to overcome the above-mentioned drawbacks by making it possible to connect the bars without the use of tools.

This invention provides insertion pieces that are inserted into the bar at both ends of the board, and a hook piece that is pushed into the upper edge of the side wall of the bar and fits on the upper edge of the board,
Further, a bar connecting fitting is provided in which hook pieces are provided at both ends with claw pieces that engage with the upper bent wall of the side wall to prevent the horizontal bars from falling off from the vertical bars.

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

In the figure, reference numeral 1 denotes a board, and insert pieces 2.2 are provided at both ends of the board 1, each protruding in the same direction.

The above-mentioned insertion pieces 2.2 are formed by bending them in series from both ends of the board 1 as shown in the figure;
There are cases where another insertion piece 2.2 is fixed to the board 1 by welding or the like (not shown).

Furthermore, a hook piece 3 is provided on the upper edge of the board 1, which protrudes in the opposite direction of the insertion piece 2 and is fitted by pushing into a bent wall that extends inwardly from the upper edge of the side wall of the bar.

The above-mentioned hook pieces 3 are bent and connected from the upper edge of the vertical plate 4 by a single leaf spring, and after the vertical plate 4 is stacked on the board 1, the hook pieces 3 are attached to the board 4 by caulking studs 5.
Although the vertical plate 4 and the vertical plate 4 are integrated, a hook piece 3 may be provided in series from the upper edge of the substrate 1.

Further, both ends of the hook piece 3 are provided so that when the hook piece 3 is fitted to the upper edge of the side wall of the bar, the hook piece 3 engages with the lower surface of the downward edge of the bent piece wall that extends from the upper edge of the side wall of the bar and protrudes inward. A matching claw piece 6 is provided.

The above-mentioned claw piece 6 has a slit 7 formed in the hook piece 3, and is made to protrude so that the lower side of the slit 7 becomes the claw piece 6.

The bar connecting fitting according to this invention has the above-mentioned configuration. Next, the connection method will be explained. When connecting the end of the row bar A1 to one or both sides of the column bar A, first, the row bar ^A1 is connected to the end of the row bar A1. Insert the insert piece 2.2 inward from the end face of the.

After that, the hook piece 3 is pushed into the inwardly bent side wall 9 of the upper edge of the side wall 8 of the vertical bar A, and the hook piece 3 is overlapped with the bent side wall 9 to fit the side surface of the vertical bar A. The ends of row bar A ¹ can be connected.

Further, when the hook piece 3 is fitted, the claw piece 6 is pushed back by the bent piece wall 9, and when the hook piece 3 overlaps the bent piece wall 9, the claw piece 6 faces the downward edge of the bent piece wall 9. It is possible to prevent the horizontal bar ^A1 from lifting up or falling off.

Furthermore, connection can be made easily and quickly without using any tools, and work efficiency can be significantly improved.
