Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an escalator, and particularly to an improvement in the support structure of an escalator in which at least one of the upper and lower ends of a truss is movably supported by upper and lower floors of a building.

In recent years, as buildings and other structures have become taller, they have become more flexible (earthquake resistant).

Therefore, when an earthquake occurs, the shaking of the building causes a large relative displacement between each floor.

For this reason, various improvements have been made to the support structure of escalators installed between floors so that they can quickly respond to the above-mentioned displacement differences.

In the conventional escalator 10, as shown in FIG. 1, a truss 12 is supported by an upper floor 14 and a lower floor 16 of the building.
is fixed to the floor side with a mounting bolt or the like, but its lower end (casing or upper end) is movably supported as shown in FIGS. 2 and 3.

That is, in the building, a beam 18 is fixed to the lower floor 16 of the building, and an anchor plate 20 is fixed to the upper part of the beam 18.

On the other hand, a cantilever member 22 is fixed to the lower end of the truss 12 of the escalator, and this cantilever member 22 is placed on the anchor plate 20 and supported so as to be able to freely come into sliding contact with the anchor plate 20.

A board 24 is fixed to the upper part of the truss 12.

The tip of this board 24 is supported by a slide board 26,
Sliding contact is possible.

This slide plate 26 is attached to the lower floor 16.

As a result, the escalator 10 has an integral support structure with the upper floor 14 of the building, and has a structure that swings according to the movement of the upper floor 14 but is not affected by the movement of the lower floor 16.

That is, when an earthquake or the like occurs, relative slip occurs between the boarding board 24 and the slide board 26, and between the cantilever member 22 and the anchor plate 20, and this slip absorbs the displacement difference between each floor. This prevents excessive loads from being applied to the

However, since the shaking motion of the building is complicated, the boarding board 24
There is not only a mere sliding action in the lateral direction but also a relative displacement in the vertical direction between the slide plate 26 and the slide plate 26.

From this point of view, the boarding board 24 is made of a resilient steel plate or the like so as not to cause vertical deformation to the floor side of the building.

On the other hand, it has recently become desirable to provide the boarding board 24 with beautiful decorations similar to those applied to the floors 14 and 16.

For this reason, each floor is usually covered with a brittle material with low mechanical strength, such as P-tile.

However, since the boarding board portion undergoes considerable deformation when an earthquake or the like occurs, it has been difficult to decorate the boarding board portion in the same manner as the floor using decorative plates such as P tiles.

This idea was made in consideration of the above-mentioned points, and by improving the connection (support) between the escalator and the floor, which has boarding boards, etc., the boarding and alighting positions can be decorated in the same way as the floor surface. The purpose is to provide an escalator that allows

An embodiment of this invention will be described below with reference to the accompanying drawings.

In FIGS. 4 to 7, the reference numeral 28 is the encalator
This shows a truss that supports 0, and this truss 28
The lower and upper ends of the truss 28 are supported by the building floor 30 forming each floor of the building, while the truss 28 movably supports each step 32 of the escalator 109.

The lower end or upper end of the escalator 10 is movably supported.

An H-shaped beam 34 is fixed to the lower part of the building floor 30, and a cantilever member 36 is attached to an anchor plate 38 on this H-shaped beam 34.
It is placed through.

This cantilever member 36 is fixed to the tip wall of the lower end of the truss 28, and is slidably mounted on the anchor plate 38.

A comb board 40 and a board 42 are provided adjacent to each other between the step 32 and the building floor 30 so that passengers can walk on and off the vehicle.

The comb plate 40 is provided with comb teeth 44 that engage with grooves provided in the step 32.

The comb teeth 44 are mounted on the truss 28 via a support member 46 and held substantially horizontally so as to be flush with the building floor 30.

The housing plate 40 is made of an elastic plate such as a steel plate.

First, the board 42 has a box shape to increase its mechanical strength, and its upper surface is held flush with the building floor 30 and the comb board 40.

One side of the board 42 is fixed to the building floor 30 with mounting bolts, etc., and the other side extends on the truss 28 toward the comb board 40 and faces the comb board 40.

A slide plate 48 is fixed to the other end of the board 42 with attachment means 50 such as bolts and nuts, and the comb plate 40 is in slidable contact with the upper surface of the slide plate 48.

The length of the slide plate 48, the getting on/off plate 42 and the comb plate 4
The gap with 0 is designed to absorb the difference in displacement caused by the shaking of the upper and lower floors.

The gap is adjusted to, for example, several tens of degrees.

The side portions of the casing, the board 42 and the comb board 40 are held as shown in FIGS. 6 and 7.

In this figure, reference numeral 52 indicates the boarding board 42 and the comb board 40.
It is a parting plate that surrounds only the step side and is supported by receiving plates 54 and 55.

The receiving plates 54 and 55 are fixed to the concrete constituting the building floor 30 with anchor bolts 56 and the like.

The receiving plate 54 projects above the truss at the lower part of the board 43 of the housing and holds the board 42 with screws 58, and one receiving plate 55 ends in front of the truss 28 and the comb plate 400.

It should be noted that surrounding the board 42 with the partition board 52 as described above and screwing it to the receiving board 54 is convenient for opening and closing when inspecting the inside of the escalator.

The movable support part as described above can be provided on the lower floor, the upper floor, or both the upper and lower floors.

If the upper floor (casing or lower floor) is provided with movable supports, the lower floor (casing or upper floor) is provided with trusses that connect to the floor in the same way as in conventional rigid buildings. It is fixed with a mounting bolt or the like (not shown).

Now, in the structure of the escalator according to the present invention, as mentioned above, the boarding board is fixed to the building floor, and the movable support part of the escalator is replaced between the boarding board and the comb board.
The rigidity of the board can be increased accordingly, increasing the mechanical strength.

Therefore, according to this invention, even if the upper surface of the boarding board is covered with P-tiles, etc., they will not be destroyed, and the decorative part of the building floor will be spread out closer to the escalator.
