Abstract

PURPOSE:To carry temporary stairs in with a small lifter without transferring exhibitions in a store, when a temporary stair formed accessible in both directions is set up during reforming an escalator, by dividing and forming plural steps. CONSTITUTION:A temporary stair formed accessible to both directions is set up during reforming an escalator. In this case, temporary stairs 101-10n as divided into plurals are fixed to respective frames 1 fixed to the respective bodies 8a, 8b of a building. The temporary stairs 101-10n are formed by welding footplates 10b1-10bn between pairs of baseboards 101a-10na. The baseboards 101a-10na are formed to be continuously approximated to the frames 1 in shape, brackets 11a1-11an being welded to the opposite face side thereof in proper spaces. In this way, the temporary stairs 101-10n are carried to the frames 1 with a small lifter without transferring exhibitions in a store.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary stairway for an escalator.

[0002]

2. Description of the Related Art With the deterioration of existing escalators,
The frame, which is a structural member that is welded to the building's structure and that hardly deteriorates, is diverted as it is, and the escalator is newly removed to replace all other products with new parts. For example, a conventional installation work for removing the parallel escalator will be described with reference to FIG.

Rails 3a and 3b are mounted via a rail bracket 2 inside a frame 1 which is a structural member of an escalator which is firmly fixed to a receiving beam of a building body, and above the rails 3a and 3b. Is connected by a step chain (not shown) to run. Frame 1
Above the balustrade is the balustrade 5 and the inner decks 6a, 6 located on either side of it.
b and the outer decks 7a and 7b are attached. Two such escalators are installed side by side to form a side-by-side escalator.

[0004] In the case of performing a new construction work for removing the escalators that are installed side by side, it is possible to pass in both directions at the same position as before without detouring to the stairs or the like even during the new construction work period for the removal work. For one of the frames of the escalator, the integral staircase 10 was installed on the frame 1 via the bracket 9 as shown in FIG.

[0005]

However, in the case of the integral type temporary staircase as described above, the total length of the temporary staircase becomes longer as the floor height of the escalator increases.
When transporting to a frame of an escalator where a long temporary staircase is installed, it is necessary to take a large space for a large carry-in entrance and a carry-in passage. Especially in the case of an escalator installed in a department store, etc., where the escalator is located far away from the doorway of the building or on a floor other than the doorway, there is a showcase in the store to carry the long temporary stairs to the frame. Or move exhibits,
Sometimes it is necessary to make a hole in the outer wall as a carry-in port,
A lot of time and money was spent on these preparation work and recovery work.

Further, since the weight of the temporary stairs also increases, a large lifting device is required for loading and installing.

An object of the present invention is to provide a temporary stairway for an escalator, which has good workability at the time of loading and installation and can reduce the influence on the building.

[0008]

In order to achieve the above object, the present invention is installed on the frame of either one of the above escalators and the other of the two escalators at the time of remodeling work of the two escalators arranged in parallel. The temporary stairs of the escalator, which is configured to be able to pass in both directions even during the remodeling work, is divided into at least two or more.

[0009]

The temporary staircase of the escalator according to the present invention is divided into at least two pieces and installed on the frame of the escalator as described above. Therefore, in order to carry the temporary staircase to the frame, a showcase or an exhibit in the store can be installed. It is possible to carry it in and install it without moving it, and with a small lifting device.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

Here, FIG. 1 is a side view of a temporary staircase of an escalator according to an embodiment of the present invention, FIG. 2 is a sectional view taken along line AA of the temporary staircase of the escalator shown in FIG. 1, and FIG. FIG. 3 is an enlarged perspective view of an essential part of FIG.

1 and 2, the building bodies 8a, 8
The frame 1 is fixed to b, and the divided temporary stairs 10 ₁ , 10 _{2 to} 10 n are fixed to the frame. The temporary stairs 10 ₁ , 10 ₂ to 10 n each include a plurality of treads 10 between a pair of skirting boards 10 ₁ a, 10 ₂ a to 10 na.
It is configured by welding b ₁ to ₁₀ bn. As shown in FIG. 1, the pair of skirting boards 10 ₁ a, 10 ₂ a to 10 na each have a shape similar to that of the frame 1 while being continuous, and a plurality of brackets are provided on the opposite side thereof at appropriate intervals. 1
1a ₁ ~11an a bracket 11b ₁ ~11bn are welded respectively. Brackets 11a _{1 to} 11an
Is fixed to the frame 1 by utilizing the preformed hole 1a of the frame similarly to the bracket 11a ₁ shown in FIG. 3 which is an enlarged perspective view, and the brackets 11b _{1 to} 11bn are also fixed to the frame 1 in the same manner. Thus the temporary stairs 10 ₁ ,
10 _{2 to} 10 n are respectively supported and configured on the frame 1. Also, for the pair of skirting boards 10 ₁ a, 10 ₂ a to 10 na,
The lower ends of the columns 10c _{1 to} 10cn are welded at appropriate intervals, and the handrails 10 ₁ are attached to the upper ends of the columns 10c _{1 to} 10cn.
d, 10 ₂ d to 10 _nd are attached.

Since the temporary staircase is constructed in this way,
At least two or more temporary stairs can be attached to the frame. Therefore, since the total length of the temporary staircase can be shortened and the weight can be lightened, even if the location of the escalator is far from the building entrance / exit at a department store, or if the escalator is installed on a floor other than the entrance / exit, the temporary staircase can be framed. Without moving the showcases and exhibits in the store to carry in, it is possible to carry in and install to the installation site with a small lifting device.

[0014]

As described above, the present invention is installed on the frame of either one of the above escalators at the time of remodeling work of two escalators arranged in parallel, and the two escalators can be moved in both directions during the rework work of the other escalator. Since the temporary stairs of the escalator that is configured to allow the passage of at least two are divided into at least two, the workability at the time of carrying in or installing the temporary stairs is good, and the influence on the building can be reduced. .
