2. Description of the Related Art As a conventional technique, Japanese Patent Laid-Open No. 2001-49
730. The grating provided in the side groove as described in 730, wherein a locking metal fitting is provided on the bottom side of the grating so as to be rotatable in a substantially horizontal plane from the longitudinal direction to the width direction of the grating. There is a grating characterized in that the stopper is configured to be rotated in the width direction so as to be locked in the side groove. In addition, as another conventional technique, Japanese Unexamined Patent Application Publication 2000-2000
-170240, a tightening nut is fixed via a horizontal plate to the lower portion of a hook portion that is hooked on a grating reinforcing plate. The upper part of the threaded rod is screwed into the tightening nut. A fixing plate is attached to the bottom of the screw rod. A positioning nut is screwed onto the threaded rod on the lower side thereof. In some cases, both ends of the fixing plate in the longitudinal direction are bent upward to form a rotation restraining piece.

However, in the former and latter forms, the locking metal fitting and the fixed plate (rotational restraint piece) are simply rotated to lock them in the side groove. In other words, it is difficult to position the locking metal fittings in the side grooves, and skill is required to securely fix them. Also, the rotation restraint piece of the fixed plate is bent upward, so it seems easy to fix (lock) it, but when removing it, it may be difficult to come off by cutting into the side groove, and when replacing the grating Cause problems.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object thereof is to provide a slide shaft that moves (projects) in the horizontal direction by rotating a fixing bolt of a grating stopper. Can be bite into the locking groove of the grooved side groove and locked, and anyone can easily apply the grating, and the slide shaft can be easily retracted by rotating the fixing bolt in the reverse direction, and the grating stopper is easier than the grooved side groove. The present invention provides a grating stopper and a grooved gutter capable of being removed.

[0005]

As means for solving the above problems, a fixing bolt is provided in a direction perpendicular to the center of a support shaft having slide shafts provided on both sides of a support shaft main body, and a coupling for connecting a grating to the fixing bolt. A slide nut is provided on both sides so that one end of the holding shaft is movably provided, and the other end of the holding shaft is movably provided on the slide shaft. Being operated in the direction. Also, the tip of the slide shaft should be formed in a pointed shape. The support shaft body must be pipe-shaped. In addition, a cushion material should be provided on the connector. Provide a co-rotation prevention stopper to prevent co-rotation of the slide nut. Furthermore, a grooved side groove in which a locking groove corresponding to the slide shaft is provided inside the side groove. In addition, the gutter must be U-shaped.
The gutter is U-shaped.

BEST MODE FOR CARRYING OUT THE INVENTION First, a grating stopper will be described. 1 is a grating stopper. 2 is
On the support shaft, slide shafts 2b each having a pointed tip are formed on both sides of a support shaft main body 2a formed by forming a hole 2a1 in a pipe-like central vertical direction so that the slide shafts 2b can be freely inserted and removed. In addition,
Below the slide shaft 2b, there is provided a mounting piece 2b1 for movably mounting one end of a holder described later. Reference numeral 3 is a fixing bolt provided in the hole 2a1 of the support shaft body 2a of the support shaft 2. Reference numeral 4 denotes a connecting tool which is provided on the fixing bolt 3 and has locking portions 4a for locking the grating frame on both sides and a hole 4b in the center. Reference numeral 5 is a slide nut screwed on the lower portion of the fixing bolt 3, and has mounting pieces 5a on both sides for movably mounting the other end of a holder described later. Reference numeral 6 denotes a plate-shaped holder, one end of which is attached to the mounting piece 2b1 by a pin 7 and the lower end of which is attached to the mounting piece 5a by a pin 8.

Next, the grooved side groove of the present invention will be described. The grooved side groove 10 is formed in a U shape,
A grating mounting portion 10a is formed on the upper portion, and locking grooves 10b corresponding to the slide shaft 2b of the grating stopper 1 are provided on both inner sides. Also, the grooved side groove 2
Reference numeral 0 is a U-shaped member having a grating mounting portion 20a formed on the upper portion thereof and locking grooves 20b corresponding to the slide shaft 2b of the grating stopper 1 provided on both inner sides. The shapes of the locking grooves 10b and 20b are not particularly limited.

Next, the construction for attaching the above-mentioned grating stopper 1 to the grooved side groove 10 will be described. First, the grating G is arranged at the required interval K on the grating mounting portion 10a of the grooved side groove 10. Subsequently, the grating stopper 1 is inserted from above the space of the required interval K, and the locking portion 4a of the connector 4 is attached to the frame W of the grating G. In this state, by rotating the fixing bolt 3 with the wrench R, the slide nut 5 rises, the slide shaft 2b projects horizontally in the holder 6, and bites into the locking groove 10b.
It is locked and fixed. The position of the slide shaft is set in advance so as to come to the position of the locking groove 10b. Also, when removing, by rotating the fixing bolt in reverse,
The slide shaft 2b retracts and can be easily removed.

As another embodiment of the grating stopper, the grating stopper 21 comprises a connecting member 24 provided with a cushion material 9 made of weather resistant rubber or the like, and a slight deviation between the slide shaft and the engaging groove. It also has a function to prevent rotation.

In the above-mentioned grating stopper, the size is to be matched with each grooved side groove, and is not particularly limited. Further, the grating stopper is ideally attached to the grooved side groove of the present invention, but it can be used by making the slide shaft bite into the generally used side groove. further,
The grating to be applied may be one that is commonly used and is not particularly limited. Furthermore, when a slide nut is screwed on the fixing bolt, it is desirable to screw it loosely. That is, it is possible to prevent the slide nut from rotating together by rotating the fixing bolt. In addition, if necessary, a co-rotation preventing stopper 34c may be attached to the connecting tool 34.
It is also a consideration to project the lower part.

[0011]

Advantages of the Invention 1) With the slide shaft that moves horizontally by rotating the fixing bolt of the grating stopper, it is possible to bite into the locking groove of the grooved side groove and securely lock it. 2) When removing the grating stopper, it can be easily removed by rotating the fixing bolt of the grating stopper in the reverse direction. 3) Since the grating stopper can be inserted and installed from above after the grating is arranged, the working efficiency can be greatly improved. By providing the co-rotation preventing stopper, it is possible to more surely attach the grooved side groove. 4) The grating stopper is ideally used for the grooved side groove of the present invention, but can also be used for general side grooves. 5) The grooved side groove can be installed more effectively by combining it with a grating stopper.
