Description

[Detailed explanation of the invention] [Industrial application field] The invention is used, for example, when repairing or renovating an existing building. This invention relates to a temporary hoistway in which a climbing pier is installed which has a landing connected to the longitudinal end of the section.

[Conventional technology]

A conventional temporary hoistway of this type was as shown in FIG.

In other words, a frame scaffolding 1 is provided in which three building frame rows 7 in which a plurality of building frames 6 are connected vertically are arranged and connected in the horizontal direction, and among the building frame rows 7 of this framework scaffolding 1, the central one and one side erect each of the ramp sections 2 between adjacent floors of the climbing pier with their lower ends located on the central building frame row 7 side, and from the upper end of the lower ramp section 2. A fabric frame 5 for folding back to the lower end of the upper slope portion 2 is erected,
A cloth frame 5' for the landing 3 was constructed between the center row of building frames 7 and the row of building frames 7 on the other side.

[Problem that the invention attempts to solve]

However, when using the conventional temporary hoistway,
Frame scaffolding requires at least three building frames placed side by side in the horizontal direction, with a width of two or more spans.For example, when placing the scaffolding on the outside of an existing building, if there are shrubbery etc. around the existing building, It is difficult to secure space for installing frame scaffolding.

Moreover, since the movement between the upper end of the ramp portion and the top of the cloth frame is back and forth, it is very inconvenient to use. However, as shown by the two-dot chain line in FIG. By erecting the fabric frame 5' for the landing 3 between the added building frame row 7' and the building frame row 7 on one side, the frame scaffold will have a width of 3 spans or more, making it even more versatile in terms of installation space. It will lack sex.

The purpose of the present invention is to reduce the installation space and improve usability.

[Means for solving problems]

The characteristic feature of the temporary elevator of this invention is that the landing is attached to the end of the building frames arranged side by side in the horizontal direction of the framework scaffolding in a state in which it protrudes outward in the direction of the arrangement, and its functions and effects are as follows.

[Effect]

Since the landing is provided as an overhang on the framework scaffolding, while the landing allows for safe and easy lifting and improves usability, it is necessary to secure space within the framework scaffold for the installation of the landing. If only the lifting and lowering of the scaffolding is considered, a frame scaffolding with a width of one span consisting of two rows of building frames will suffice.

[Effect of idea]

Therefore, the present invention has become able to provide a temporary hoistway that is easy to use and has a landing that requires a small installation space.

〔Example〕

Next, an example of the present invention will be shown.

The temporary hoistway is as shown in Figures 1 and 2.
It is constructed by assembling a staircase, which is an example of a climbing pier, to a framework scaffolding 1.

The framework scaffolding 1 has two building frame rows 7 in which a plurality of building frames 6 are vertically connected, which are arranged side by side in the horizontal direction.
Two rows of building frames 7 are connected to each other by cross braces 8, and a cloth frame 5 is constructed between the upper ends of the building frames 6 arranged side by side in the horizontal direction.

The steps are provided between each of the layers F ₁ to Fn of the framework scaffolding 1.
A staircase section 2 (an example of a ramp section) extending from each of the above
The staircase is made up of a landing 3 connected to an end of the staircase portion 2 in the longitudinal direction, and a staircase handrail 4.

The stair portion 2 has a width that is half the width of the building frame 6, and when viewed from the front, there are gaps between adjacent floors F _U ,
A zigzag arrangement in which the lower end of the staircase part 2 spanning the upper story F _U of F _L and the upper end of the staircase part 2 spanning the lower story F _L are attached to the same building frame row 7, and spanning the odd numbered stories Fo. In order to prevent the stair portion 2 and the stair portion 2 spanning even-numbered layers Fe from overlapping vertically, the stair portion 2 spanning odd-numbered layers Fo is placed on one side in the width direction, and the stair portion 2 spanning even-numbered layers Fe is placed on the other side in the width direction. It is constructed between two rows of building frames 7 in an offset arrangement.

The landing 3 has a width that is approximately equal to the width of the building frame 6, and has a width that is approximately equal to the width of the building frame 6, and a staircase portion 2 that spans the lower floor space F _L and a staircase section 2 that spans the upper floor space F _U in each layer of the framework scaffold 1. It is attached to the building frame row 7 in a state of protruding outward in the juxtaposition direction so as to form a traffic path outward in the juxtaposition direction of the building frame row 7. Specifically, as shown in FIGS. 2 and 3, it has a structure in which a road surface forming member 3B made of expanded metal is attached to a steel pipe frame 3A that is detachable from the building frame 6. The frame 3A is provided with a hook 3a in its lower part that can be freely engaged with a connecting member 6B connecting the upper ends of the pair of columns 6A of the building frame 6 and a reinforcing horizontal beam 6C from above.
A clamp 3b which can be freely attached to and detached from the support column 6A is provided at the upper part, and a handrail 3c is provided.

The cloth frame 5 has a width that is half the width of the building frame 6, and is constructed between the connecting members 6B of the building frame 6 in each layer.

According to the above-mentioned embodiment, since the stair portions 2 are arranged in a zigzag pattern, only one landing 3 is required for each level for traffic between the stair portions 2.

[Another example]

Examples of the present invention will be shown below.

[1] As shown in FIGS. 4 and 5, between the rows of frames 7 of the framework scaffolding 1 shown in the above example,
The stair portions 2 spanning each of F ₁ to Fn are all constructed in the same posture, and a cloth frame 5 for forming a passage is constructed so as to form a passageway between the stair portions 2 and the cloth frame 5. The landing 3 is attached to the building frame row 7 so as to protrude outward in the juxtaposed direction.

[2] In the above embodiment, the landing 3 is
It is configured to be freely foldable or disassembleable in a state separated from the building frame row 7.

[3] In the above embodiment, a staircase is shown as the climbing pier, but the climbing pier may be a footboard or a footboard with a non-slip pier.

[4] In the above example, as the framework scaffolding 1, 2
Although the present invention is applied to a structure in which two building frame rows 7 are arranged side by side, the present invention can also be applied to a structure having a framework scaffold 1 in which three or more building frame rows 7 are arranged in parallel. Note that although reference numerals are written in the claims section of the utility model registration for convenience of comparison with the drawings, the present invention is not limited to the structure of the attached drawings by such entry.
