Has to be corrected sequentially with a hammer or the like, and as in the above case, there is a problem that it takes a lot of work.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a rail support structure of a vertical transport apparatus capable of performing an efficient, easy, and high-precision construction work, and a method of constructing the rail.

[0008]

In order to achieve the above-mentioned object, the technical means of the rail support structure of the vertical transport device is such that guide rails of a predetermined length are sequentially arranged continuously over each floor in the vertical direction, and are mutually connected. In a rail support structure of a vertical transport device provided with a connected vertical guide rail portion and a transport vehicle guided up and down along the vertical guide rail portion, each unit rail configuration constituting the vertical guide rail portion A guide rail having substantially the same length as the pitch between the floors; a support bracket positioned at an upper end of the guide rail and provided in a protruding manner in a direction opposite to the ascending and descending side of the carrier; and a guide rail. Is slidably engaged only in the longitudinal direction of the guide rail along the surface of the support bracket projecting side, and is fixed to the guide rail. And a supporting bracket of the unit rail structure is mounted on the upper surface of the floor portion in a mounted state, and the slide connecting device is provided at an upper end of the guide rail of the lower unit rail structure. The point is that it is fixed to the guide rail in a state of straddling the edge and the lower end edge of the guide rail of the unit rail structure on the upper side.

[0009] In the rail construction method, a guide rail of a predetermined length is sequentially arranged continuously over each floor in a vertical direction, and a vertical guide rail portion connected to each other is provided. In the rail construction method of a vertical transport device provided with a transport trolley guided up and down along the upper and lower positions of guide rails having a length substantially equal to the pitch between floors, the trolley extends in a direction opposite to the vertical direction of the transport trolley. The support bracket of the unit rail structure provided with the support brackets in a shape is placed at the mounting position on the upper floor side of the upper floor to support the unit rail structure, and then disposed in the vertical direction in advance. The upper edge of the guide rail of the lower unit rail assembly and the lower end of the guide rail of the upper unit rail assembly supported on the upper surface of the upper floor. And then slidably engaged with the guide rail of the unit rail structure along the surface of the support bracket overhanging side only in the longitudinal direction of the guide rail, and fixed to the guide rail. The slide connector provided releasably in advance is extended in the longitudinal direction of the guide rail so as to span the upper edge of the guide rail of the lower unit rail assembly and the lower edge of the guide rail of the upper unit rail assembly. After sliding, the slide connector is fixed to the guide rail, and then the support bracket of the upper unit rail structure is fixed to the upper surface of the upper floor.

According to the present invention, the guide rails of the lowest unit rail structure are accurately arranged in advance so that the longitudinal direction thereof is vertical. Next, when disposing the upper unit rail structure, the support bracket of the upper unit rail structure is placed at the mounting position on the upper surface of the upper floor to support the unit rail structure. By doing so, a state is obtained in which the upper end of the guide rail is swingably supported on the floor of the upper floor via the support bracket.

Then, the guide rail of the upper unit rail structure is swung so that the lower edge of the guide rail coincides with the upper edge of the guide rail of the lowest unit rail structure, and the upper or lower guide is formed. Sliding operation of the slide connector previously mounted on the rail is moved to a position that straddles the upper edge of the guide rail of the lowermost unit rail assembly and the lower edge of the guide rail of the upper unit rail assembly. . If the slide coupling is fixed to the guide rail in this state, the upper guide rail is accurately held in the vertical direction along the lower guide rail.

That is, when the upper guide rail and the lowermost guide rail do not coincide with each other in the vertical direction, even if the slide connector is slid, the upper end of the guide rail of the lowermost unit rail structure is operated. A state that straddles the edge and the lower edge of the guide rail of the upper unit rail structure cannot be obtained,
When the upper guide rail and the lowermost guide rail are vertically aligned, if the slide connector is operated, the upper end edge of the guide rail of the lowermost unit rail structure and the upper unit are formed. A state of straddling the lower edge of the guide rail of the rail structure is obtained, and the upper guide rail is positioned vertically along the lowermost guide rail by the sliding operation of the slide connector. You can easily grasp whether it is.

When the lower edge of the upper guide rail is matched with the upper edge of the lowermost guide rail,
Since the upper unit rail structure is swingably supported on the floor of the upper floor, the operator does not need to support the weight of the guide rail, and can perform the alignment work efficiently and easily.

Thereafter, the support bracket of the upper unit rail structure may be fixed to the upper surface of the upper floor.

[0015] In the same manner, higher order unit rail components may be sequentially arranged.
