Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a telescoping device for a running rail installed on a rooftop.

[Problems to be solved by this invention]

As shown in Fig. 1, on the roof R of the building, two running rails 3 for the gondola crane cart 2 are installed in parallel so that the washing gondola 1 for window cleaning can be positioned around the four circumferences of the building. It is located in
Such a running rail 3 is formed into a substantially rectangular annular shape from the long side direction running rail 3A and the short side direction running rail 3B, and because of this shape, the running rail 3 due to heat in the long side direction and the short side direction It is necessary to absorb the expansion and contraction of

Furthermore, as shown in Figure 1, the central part of the building is
If RC construction A and both sides are S construction B,
Since the deformation caused by earthquakes and wind is different, it is necessary to absorb this difference in the amount of deformation.

[Purpose of the invention]

The present invention has been proposed in view of the above circumstances, and its purpose is to provide a telescoping device that can simultaneously absorb deformation in the long side direction and the short side direction of a pair of running rails.

[Structure of the invention]

The expansion and contraction device according to the present invention is an expansion and contraction device for two running rails arranged in parallel, and is formed by connecting the rails by a joint rail, and a sliding device on the lower surface of the base end of the joint rail. The base end of the joint rail is pivoted to the shaft provided at the end of one of the rails by fixing the plate and allowing the sliding plate to swing horizontally on the mounting flange fixed to the foundation. A sliding plate that can slide and swing horizontally on a fixed plate fixed on the foundation is fixed to the lower surface of the end of the rail, and the end surface of the joint rail is tilted forward on the outside of the track. The end surface of the other rail is an inclined surface corresponding to the slope, and the ends of a pair of joint rails are connected in the track width direction by a member that connects them while urging each other inwardly. engages the other rail at the tip of the
A joint plate is provided that can prevent the joint rail from moving inward on the track.

〔Example〕

The present invention will be described below based on an illustrated embodiment. As shown in FIGS. 1 and 2, the expansion and contraction device 4 according to the present invention is equipped with an RC
A total of four locations are provided on the long side running rail 3A on the structure A. Therefore, as shown in Fig. 2, the running rails are a straight running rail 3A' that is disposed up to the front of S-structure B, and a short side running rail 3B.
It is divided into a substantially U-shaped running rail to which a short running rail 3A'' is integrally connected.

The running rail 3A' and the running rail 3A'' are connected by a joint rail 5 of the expansion/contraction device 4.

As shown in FIGS. 3 and 4, the joint rail 5 has its base end connected to the rail 3 so that it can swing horizontally.
A". In other words, a sliding plate 6 is integrally attached to the lower part of the base end of the joint rail 5, and a sliding plate 6 is attached to the base end of the joint rail 5. A sliding plate 6 is inserted between the flange 8 and the lower surface of the end of the rail 3A'', and the protruding pin 9' of the shaft 9 protrudes from the sliding plate 6 to attach the mounting flange 8.
and is secured with a nut 10.

The end surface of the joint rail 5 is an inclined surface 11 (for example, inclination angle α=30°) that slopes forward toward the outside of the track, and the end surface of the rail 3A' is also formed into the inclined surface 11 with a gap. Corresponding slope 1

A sliding plate 13 that can extend to the lower surface of the end of the rail 3A' is provided on the lower surface of the tip of the joint rail 5.
is installed, and this sliding plate 13 is attached to the steel foundation 14
It is supported by a fixed plate 16 attached to an auxiliary foundation 15, and is capable of sliding and swinging in the horizontal direction.

Furthermore, a joint plate 17 that can extend to the outer surface of the web at the end of the rail 3A' is fixed to the outer surface of the web at the tip of the joint rail 5, so that the tip of the joint rail 5 moves inward of the track. is preventing you from doing so.

In addition, the tips of the pair of joint rails 5 in the track width direction are connected by a member 18 that connects while urging the track inward, thereby regulating the amount of outward opening of the ends of the joint rails 5. are doing.

As shown in FIGS. 3 to 5, this member 1
8 is a locking member 19 attached to the lower surface of the slide plate 13 on the rail 5 side, and a connecting bar 20 whose end passes through the locking member 19 and connects the pair of locking members 19 in the track width direction. , one end is blocked by a nut 21 screwed onto the end of the connecting bar 20, and the joint rail 5
It consists of a spring member 22 that can bias the tip end inward of the orbit.

In such a configuration, as shown in FIG. 5, in the direction in which the joint rail 5 moves forward, the tip of the rail 5 is pushed outward to absorb the displacement in the long side direction. Become. In the direction of retreat, the gap between the inclined surfaces 11 and 12 only widens. In this case, the joint plate 17 is connected to the rail 5 and the rail 3.
A' is connected and the rail 5 does not move inward of the track.

For displacement in the short side direction, as shown in FIG. 6, the ends of rail 5 and rail 3A' are
They are connected in a swingable manner via the joint plate 17, and the rail 5 swings around this portion to absorb displacement.

Further, in any of the displacement states, the joint rail 5 does not protrude inward from the track, and the crane truck can travel.

In addition, as shown in Figures 7 and 8, RC construction A
The foundation is a steel frame foundation 23, as shown in Figures 9 and 10.
As shown in the figure, in the case of S-Building B, the concrete foundation is 24, and reinforcing material 25 is installed between the rails.
is installed.

〔Effect of the invention〕

Since the telescoping device according to the present invention has the above-described configuration, it is capable of simultaneously operating a pair of parallel running rails, absorbing deformation in two directions at the same time, and is capable of simultaneously absorbing deformation of the crane truck in any deformed state. It is possible to run.
