Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a main frame of a curved escalator having a conveyance path having an arcuate shape in a horizontal projection plane.

[Prior art mr] A circular curved escalator has an arc shape in a horizontal projection plane and is provided with a main frame constituting a conveyance path having a lower horizontal portion and an inclined portion connected to the horizontal portion.

That is, as shown in Fig. 1, a circular curved escalator (1
), the conveyance path (2) along which the step (3) moves is spirally formed into an arc shape as shown in FIG. 2 in a horizontal projection plane. The stepper (3) is connected to an endless belt (5) housed in the main frame (4), and is driven by a drive source (6) together with the handrail (7), or is driven by the former conveyance path (2). It has been proposed that the main frame (4) is constructed by connecting a number of truss units as shown below.

That is, although FIG. 3 is a diagram showing a horizontal projection plane of the main frame (40) constructed by connecting a large number of truss units,
Truss units (40a), (40b), (40c)
-(40n) are arranged in rows 11-r and on curves connected by smooth arcs drawn with radii of curvature R1 to ffR5 centered on centers 01 to 05. These truss units (40a), (40b), (40c)-(40n
), the horizontal part and the inclined part of the step forming the conveyance path were directly connected to have one bending point.

That is, the upper and lower chord members forming the horizontal portion of the truss and the upper and lower chord members forming the sloped portion of the truss are connected so as to be bent only at the intersections of these horizontal portions and the sloped portion. A vertical member is provided in the chord member, and a cross member is suspended between the outer truss and the inner truss, and the escalator rail is provided on this cross member along the longitudinal force plane of the conveyance path.

However, in the past, the above-mentioned chord members were connected only at the intersections with the horizontal and inclined parts of the truss, making it difficult to determine the target location for the additional issue. The work of arranging the horizontal timbers between the vertical timber floors was complicated. Furthermore, since there was no suitable reference point, it was troublesome to center the truss.

[Summary of the Invention] The present invention has been made based on the circumstances stated in 2 above. The purpose is to provide a main frame for a curved escalator that facilitates centering.

[Embodiment of the Invention] An embodiment of the present invention is described below with reference to the drawings; Ht, 4 (,
I will explain.

FIG. 4 is a side view of an outer truss in a truss constructed by connecting truss units, and FIG. 5 is a side view of the inner truss. In these figures, A1+
A2, Dl, B2 and B1, B2, El, B2 are made to face each other and formed into a cube as one unit, An, D.
A toss (40) is constructed by connecting n, Bn, and En.

Truss width direction) - (40a), (40b), (40c)
・=(40n) is the lower chord material (41) and the lower chord material (42
), the vertical member (43) installed vertically between the second and lower chord members (41) and (42), and the upper and lower chord members (41) and (
42) and the diagonal members (44) that extend across the quadrilateral formed by the longitudinal members (43).

The above-mentioned outer truss and inner truss are formed in a shape in which a horizontal part H and an inclined part S at both ends are connected by a bent part B as R4, as in the oral tradition. This bent part B is the upper chord material (4
1) and the lower chord member (42) are bent in multiple stages, two stages in this embodiment, and are connected to the horizontal part H and the inclined part S, respectively.

By the way, in the past, L horizontal 81! H and the slope S are (
i) Flood! As shown by the lines, it was bent only at these intersection points, which had the drawbacks mentioned above.However, in the present invention, as described above, the upper and lower chord members are bent in multiple stages through the bent part B. A vertical member (43) is provided at the bending point of the bent portion B so as to be connected to the linear inclined portion S. That is, outside I in FIG.
・Place the vertical member (43) between the G string member (41) and the -G string member A (42) as shown in the truss side view and the inner truss side view in Figure 7. But in this case,'';
Bending points bIC1, b2 of lower chord members (41) and (42)
The vertical members (43) are attached to the yaws Cz and b in such a way that the negative faces of the vertical members (43) are oriented toward the center jξ of the polygonal truss as shown in FIG. This results in vertical members (43), (4
3), the horizontal member (44) installed horizontally on the truss center position and the vertical member (44)
43), 11 sentences connecting (43). Several phrases will be said in parallel for each sentence 3.

The above bending points b1-c1. b2-c2. b3-c3
may be a vertical cutting portion cut along the vertical IO line instead of the vertical bending portion. The entire cutting part does not need to be vertical, and it is sufficient that it be vertical at least at a position a few points above the tip of the edge material (43).

FIGS. 9 and 10 are an enlarged plan view and an enlarged side view of a vertically bent portion or a vertically cut portion of a chord member. In more detail based on these figures, the vertical member (43) is fixed at one end with the vertical bent part or vertical cut part (45) of the two-chord member (41), (41) as 11 marks. The other end of the j-marked vertical member (43) may be fixed with the vertical bending portion or vertical cutting portion of the lower chord member omitted as the target.

[Effects of the Invention] With the above structure, the vertical members can be placed targeting the vertically bent or vertically cut portions of the chord members, making the installation work easier.

In addition, several rows of horizontal members in the width direction of the truss are arranged on the longitudinal members, and centering of the truss is facilitated.
