A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numerals 1A and 1B denote fixed racks installed on a floor, and 2A and 2B denote moving racks. The racks 1A to 2B are arranged side by side in parallel with each other, and the movable racks 2A and 2B are fixed on the positioning guide rail 3 and the seat rails 4 and 5 laid on the floor between the fixed racks 1A and 1B. The racks 1A and 1B are supported so as to be able to move laterally in a direction connecting the racks 1A and 1B. By the lateral movement of the movable racks 2A and 2B, a work passage A can be formed between any two adjacent racks 1A and 2B.
[0007]
The movable racks 2A and 2B have two flanged wheels 6a and 6b which engage with the positioning guide rail 3, and two flangeless wheels 7a and 7b and 8a and 8b which roll on the seat rails 4 and 5, respectively. Are pivotally supported, and the flanged wheels 6a and the flangeless wheels 7a, 8a on the same side are driven forward and reverse by a drive shaft 10 interlockingly connected to a motor 9, thereby moving the movable racks 2A, 2B back and forth. It can be moved.
[0008]
The buried rail device of the present invention can be used as, for example, the seat rails 4 and 5 in the above-described movable rack device, and has grooves formed on the floor surface 11 as shown in FIGS. A rail strip 13 is arranged in the surface 12 so that the surface 13 a is flush with the floor 11, and the space inside the groove around the strip 13 is filled with a synthetic resin 14 and cured. Under the rail band plate 13, projecting plates 15 projecting from the band plate 13 to both left and right sides are attached at appropriate intervals in the length direction of the band plate 13.
[0009]
The connection between the rail strip 13 and the overhang plate 15 is made by using a counterbore hole 16 provided on the rail strip 13 and a female screw hole 17 provided on the overhang plate 15 as shown in FIGS. This can be done by using a dish-shaped headed bolt 19 having a square hole 18 for rotating operation. The bolt 19 has a length protruding below the overhang plate 15 as shown in FIG. Further, as shown in FIG. 4, the overhang plate 15 can be fixed to the back surface of the rail strip 13 by welding 20. Of course, the overhang plate 15 can be fixed to the rail band plate 13 by using the bolt 19 and the welding 20 together.
[0010]
In FIG. 2, reference numeral 21 denotes an overhang plate serving also as a rail connection plate. When the rail strips 13 having a unit length are arranged in the groove 12 with their end faces abutting each other, the overhang plate 21 also serves as the rail connection plate. Are disposed so as to straddle between the butting ends of both rail strips 13, 13, and the overhang plate 21 is attached to both rail strips 13, 13 with bolts 19 or the like.
[0011]
It is necessary to position and hold the rail strip 13 at a predetermined position in the groove 12 before filling with the synthetic resin 14. An example of this method will be described with reference to FIGS. A temporary fixing bracket 22 made of an angle material longer than the width of the groove 12 is provided on the surface 13a side of the rail strip 13 at a position at an appropriate interval in the length direction of the rail strip 13 and a rail. It is temporarily fixed with a bolt 23 so as to be orthogonal to the band plate 13 and to project both ends equally. With the rail strip 13 fitted into the groove 12 and adjusted to a predetermined position, both ends of the temporary fixing bracket 22 abutting on the floor surface 11 on both sides of the groove 12 are fixed with concrete nails 24. Fix with such as. As a result, the rail band plate 13 is firmly positioned and held at a predetermined position in the groove 12, so that the synthetic resin 14 is filled in such a state. When the synthetic resin 14 has hardened and the desired strength is obtained, the bolts 23 may be removed, the concrete nail 24 or the like may be removed, and the temporary fixing bracket 22 may be removed.
[0012]
In addition, as shown in FIG. 7, at both ends of the overhang plate 15, bent end portions 15 a that bend obliquely outward and downward are formed, so that the support strength and the positioning strength of the rail strip 13 can be increased. . Further, although different from the technical idea of the present invention described in claim 1, it is conceivable that the overhang plate 15 is continuous over the entire length of the rail strip 13 as shown in FIG. 8, or as shown in FIG. It is also conceivable to integrally form the portion corresponding to the overhang plate 15 with the rail band plate 13. In the drawing, reference numeral 23a denotes a screw hole for screwing the bolt 23 for attaching the bracket 22 for temporary fixing. The overhang plate integral molding can be applied to the overhang plate 15 in the embodiment shown in FIGS. 2 to 6 and the overhang plate 15 shown in FIG.
