Abstract

PURPOSE:To form a groove, in which the collar section of a collar wheel travels on a rail, on which the collar wheel travels. CONSTITUTION:A side rail 6 is laid on a concrete layer 14. Grooves 12 are formed linearly at both left and right end sections of the side rail 6 in the longitudinal direction. A moving shelf 16 is supported and guided to the side rail 6 through a collar wheel 13, and installed movably. Collar sections 13a travel in the grooves 12 with travelling on the side rail 6 of the collar wheel 13. The grooves 12 are molded integrally with the side rail 6, thus omitting labor hour, in which the grooves are shaped through novel welding and cutting work.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] The present invention relates to a rail laying structure for supporting and guiding a movable body such as a movable shelf, a small crane, or a trolley through wheels with flanges when the movable body is installed on an existing floor. It is something.

0002

2. Description of the Related Art Conventionally, there is a rail laying structure of this type as shown in FIG. That is, 25 indicates a movable shelf, which has wheels 26 with flanges and wheels 27 without flanges. A plurality of rails 28 and 29 are provided to support and guide the movable shelf 25 via these wheels 26 and 27.

Of these, the rail 2 on the side of the wheel without brim 27
9 is supported by anchor bolts 32 driven into the existing floor 31 via a support plate 30. Furthermore, the rail 28 on the side of the flange wheel 26 is provided inside a plate 33 that is bent into a concave shape, and the plate 33 is supported by anchor bolts 32 driven into the existing floor 31 via the support plate 30. ing. The anchor bolts 32 and the support plate 30 are buried in the concrete layer 34, and the upper surface of the rails 28, 29 and the plate material 33
The upper end surface is flush with the upper surface of the concrete layer 34.

When the movable shelf 25 travels while being supported and guided by the rails 28 and 29, the flange portion 26 of the flange wheels 26
a runs in a groove 35 formed between both side surfaces of the rail 28 and both vertical plate portions of the plate material 33.

[0005]

According to the above conventional method, in order to form the groove 35, the rail 28 was provided by plug welding to the inner surface of the bottom plate of the plate material 33. For this reason, drilling and welding work during plug welding, and spatter cleaning work after welding were time-consuming.

An object of the present invention is to provide a rail laying structure that can easily form a groove in which the flange portion of a flange wheel runs.

[0007]

[Means for Solving the Problems] In order to achieve the above object, a rail laying structure according to the present invention includes a rail that supports and guides a movable body that can run freely via wheels with flange, which is disposed on an existing floor, A groove in which the flange portion of the flange wheel runs is integrally molded on both sides of the rail, the rail is supported by an erection tool via a fixing device, and the fixing device and the erection device are buried in a concrete layer. .

[0008]

According to the structure of the present invention, the movable body travels while being supported and guided by the rails via the flanged wheels. At this time, the collar portion runs in the groove.

[0009] Since the groove is integrally formed with the rail, no welding is required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. As shown in FIGS. 1 and 2, a plurality of construction tools 4 consisting of anchor bolts 2 and support plates 3 are linearly provided on an existing floor 1 at appropriate intervals in the front-rear direction.

[0011] The anchor bolts 2 are driven into the existing floor 1 in pairs on the left and right, and between the upper parts of these anchor bolts 2,
A support plate 3 is installed via upper and lower nuts 5. Thereby, by rotating the upper and lower nuts 5, it is possible to adjust the height of the support plate 3 during construction.

A rail mounting surface 3a is formed at the center of the support plate 3 and projects upwardly from both ends. Rails 6 and 7 are laid on this rail mounting surface 3a in the front-rear direction, and are fixed by clamp members 8, which are an example of a fixture. That is, the rails 6 and 7 have a convex shape, and clamp engaging portions 6a and 7a are formed at both left and right ends.

The clamp material 8 is a plate material with an L-shaped cross section, and is attached to both the left and right ends of the rail mounting surface 3a via bolts 9 and nuts 10, and one end is attached to the clamp locking portions 6a and 7a. The vertical portion of the other end is supported by the rail mounting surface 3a. Above bolt 9, nut 10
By tightening, the clamp locking parts 6a, 7a are pressed downward by the clamp material 8, so the rails 6,
7 is firmly fixed to the rail mounting surface 3a.

Of the rails 6 and 7, grooves 12 are formed in the left and right ends of the upper surface of the side rail 6, respectively, in a straight line in the front and back direction. The flanges 13a provided on both sides are fitted, and these flanges 13a are guided by the inner surface of the groove 12 and can run freely.

Since the side rails 6 and the middle rails 7 are pultruded, the grooves 12 are formed integrally with the side rails 6. The above-mentioned erection tool 4 and clamp material 8 are connected to the concrete layer 14
The upper surface of this concrete layer 14 is flush with or slightly lower than the upper surfaces of the side rails 6 and middle rails 7.

As shown in FIGS. 3 and 4, a plurality of side rails 6 and middle rails 7 are arranged in parallel at predetermined positions.
A plurality of movable shelves 16 are placed on the inner rail 7 via wheels 13 with flanges and wheels 15 without flanges on the middle rail 7. Therefore, each movable shelf 16 is supported and guided by each rail 6, 7 separately on a fixed path 17, and can freely reciprocate.

18 is a wire mesh for preventing cracks. The operation of the above embodiment will be explained below. The mobile shelf 16 is
It is supported by the side rails 6 and the middle rails 7 via the flange wheels 13 and the flangeless wheels 15, and reciprocates on a fixed path 17. At this time, as the flange wheel 13 runs on the upper surface of the side rail 6, the flange portion 13a is guided by the inner surface of the groove 12 and runs along the groove 12.

Since the groove 12 is integrally formed by pultrusion forming the side rail 6, welding is not necessary. In the above embodiment, the clamp material 8 was used as an example of a fixture, but this is because the left and right ends of the rails 6 and 7 are directly connected to the rail mounting surface 3a with bolts and nuts, without using the clamp material 8. It's okay. But in this case,
It is necessary to match the longitudinal pitch of the bolt holes drilled in the rails 6 and 7 with the longitudinal installation interval of the anchor bolts 2, but when the above-mentioned clamp material 8 is used, the rail 6
, 7, there is no need to drill bolt holes in anchor bolt 2.
The rails 6 and 7 can be pressed and fixed at arbitrary positions according to the installation interval.

[0019]

[Effects of the Invention] According to the present invention having the above configuration, by integrally molding the groove in which the flange portion of the flange wheel runs on the rail, it is possible to eliminate the need for conventional plug welding to form the groove. . Therefore, the trouble of drilling, welding, and spatter cleaning after welding can be saved, and the groove can be formed easily and in a short time.
