2. Description of the Related Art A schematic structure of a passenger conveyor is shown in FIG. As shown in FIG. 18, the passenger conveyor has a main body frame 2 installed from the lower floor to the upper floor of the building. The upper beam 3 of the main body frame 2 is bolted or welded to the base 1.
The base 1 is provided with a hook 5 for supporting the balustrade 4 as shown in FIGS. 18 and 19.

When the balustrade 4 is replaced with a new balustrade for repair or the like, it is necessary to newly attach a new type of hook 5 and the base 1 for supporting the new balustrade 4 to the upper beam 3. FIG. 20 shows a state in which the existing balustrade 4, the hood 5 and the base 1 have been removed from the main body frame 2. When the existing base 1 was attached with bolts, the upper beam 3 is provided with an existing bolt. There is a hole 6. Upper beam 3
When a new type of base 1 is mounted on the base 1 by either welding or bolting, if the work site is prohibited from welding, the base 1 must be mounted by bolts. In order to attach the base 1 with bolts, the upper beam 3 needs a hole for bolting,
Since the existing holes 6 are drilled for the existing base 1, the pitch, the size, the number, and the like are often different.
It is usually impossible to divert a new type of base 1.

For this reason, in such a case, a new hole is formed in the upper beam 3 corresponding to the newly provided base 1.

FIGS. 21 and 22 show a method of forming a bolt hole for attaching the base 1 to the upper beam 3 when changing the balustrade 4. In this case, first, the working bar 20 and the center pole 21 which are working standards are attached to the main body frame 2.

According to the seventh modification, the portion not necessary for the positioning and the perforation work of the Tem plate 30 is cut off, so that the entire Tem plate 30 can be reduced in weight. For this reason, it is possible to easily carry the Tem plate 30 into the work site.

In addition to the first to seventh modifications described above, as shown in FIG. 10, the Tem plate 30 may be formed of a rollable material. This makes it easier to carry the tem plate 30 into the work site. In this case, the Tem plate 30 is made of, for example, a material capable of achieving both strength and dimensional accuracy.
For example, it may be formed of a stainless steel band or the like. Also,
The tem plate 30 may be formed of a material such as a tape that can be attached to the upper surface 3a of the upper beam 3.

Second Embodiment Next, a second embodiment will be described. FIGS. 11 to 16 are views showing a second embodiment of the present invention.

First, a base (mounting assistance frame) 50 used in the second embodiment will be described. FIG.
As shown in FIG. 12 and FIG. 12, a base 50 includes a plate (substrate) 51 and a base portion (mounting portion) 52 having a U-shaped cross section fixed to the upper surface of the plate 51 by welding.
And / or a plate-like base portion (attachment portion) 53.

The plate 51 is formed on the upper surface 3 of the upper beam 3.
It consists of an iron plate having the same width as a. Bolt holes 54 are formed in the plate 51 at positions corresponding to the holes (for example, bolt holes for attaching an existing base) which are already provided on the upper surface 3a. This bolt hole 54 is slightly larger than the diameter of the bolt to be mounted.

The base portions 52 and 53 are provided with members to be newly attached at the time of renovation, for example, at positions corresponding to the positions of bolt holes for attachment formed in a hook for receiving a balustrade.
Bolt holes 55 for attachment are formed at a predetermined pitch.

The total length of the base 50 is 1 m or less in consideration of portability. Further, on the plate 51 of the base 50, as described in the first embodiment, matching marks 55a and 55b are drawn on the edges in the longitudinal direction. "Right / Left" on the base 50,
Characters 56 indicating the method of arranging the base 50 on the upper beam 3, such as "second from the top", are entered (see FIG. 11).

Next, a method of repairing the upper beam 3 using the base 50 will be described with reference to FIG.

First, the base 50 is placed on the upper surface 3a of the upper beam 3 from which the existing balustrade, the hood, and the base have been removed.
This placing operation is performed in the same manner as the placing operation of the Tem plate 30 in the first embodiment. The method of positioning the base 50 with respect to the upper beam 3 according to the first embodiment is also performed. This is the same as the method for positioning the system plate 30.

When the base 50 is placed on the upper surface 3a of the upper beam 3, bolts are inserted into the bolt holes 54 of the plate 51, and the bolts are fastened. In this case, since the bolt hole 54 is slightly larger than the diameter of the bolt to be mounted,
Even if there is some displacement between the existing bolt hole formed on the upper surface 3a and the bolt hole 54 of the plate 51, the work of inserting the bolt into the bolt hole 54 can be easily performed.

Next, a hook is attached to the bolt hole 55 of each of the base portions 52 and 53, and a balustrade is further attached.
The renovation work of the passenger conveyor is completed. Although not shown in FIG. 11, the same operation is performed for the upper beam 3 on the opposite side.

As described above, according to the present embodiment, a base that can be newly attached to the upper beam 3 at the time of repair can be attached using the existing bolt holes formed in the upper beam 3. The perforation work for the beam 3 becomes unnecessary.

Then, similarly to the first embodiment, the plate 51 and the upper surface 3a of the upper beam 3 may be simultaneously drilled to form a bolt hole, and a bolt may be mounted in this bolt hole. In this way, for example, if only the existing bolt holes formed on the upper surface 3a of the upper beam 3 are used, the number of fastening points between the plate 51 and the upper beam 3 is insufficient, and the base 50 for the upper beam 3 is not provided.
It becomes easy to cope with the case where the mounting strength of the deficiency is insufficient.

The form of the base 50 can be modified as in the following modified examples.

First Modification First, a first modification will be described with reference to FIG. In the first modification shown in FIG. 15, the width of the plate 51 of the base 50 is the same as the width W of the upper surface 3a of the upper beam 3 only in the vicinity of both ends in the longitudinal direction, and the remaining portion is a bolt hole. The width is the minimum necessary for forming the wiring 54.
In this case, the positioning of the base 50 on the upper surface 3a of the upper beam 3 is performed using the edges near the both ends in the longitudinal direction of the plate 51.

According to the seventh modification, the plate 51
Because unnecessary parts of the function have been removed,
The entire base 50 can be reduced in weight. Therefore, it is possible to easily carry the base 50 into the work site.

Second Modification Next, a second modification will be described with reference to FIG. In the second modification shown in FIG. 16, the base 50 is formed by bending a single iron plate.

This second modified example is based on the base portions 52, 5
This is useful when it is not necessary to provide the projection 3 out of the width of the plate 51, and the plate 51 and the base portions 52, 53
And the base 50 can be easily and inexpensively formed at a lower cost than when the base 50 is formed by separately forming the base 50 and combining them.

As a third modification, the plate 51
Are formed adjacent to each other by forming irregularities such as those formed on the Tem plate 30 shown in the third modified example of the first embodiment (see FIG. 5) at the longitudinal end portions thereof. The configuration may be such that positioning between the bases 50 can be performed.

Third Embodiment Next, a third embodiment will be described with reference to FIG. In the third embodiment, the plate (substrate) 5 of the base 50 used in the second embodiment is used.
