Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary handrail for stairs used during the construction of a building, and the temporary handrail can be attached by using a part of the member for attaching the main handrail. It was done so.

[0002]

2. Description of the Related Art Conventionally, temporary handrails for stairs used during the construction of buildings are attached to stair climbing girders separately from and different from those for main construction used after final finishing. It is normal.

FIG. 4 (b) shows an example of a typical temporary handrail B ', which is a single pipe (temporary handrail 2a', temporary installation) generally used as a temporary material for construction work. The handrail 3a ') and the clamps 5 and 5'are combined.

FIG. 4 (a) shows a typical example of the permanent handrail A'in the final finished state. This is the climbing girder 6 after removing the temporary handrail B'in FIG. 4 (b). And the attachment plate 1'under the main installation handrail 2'are integrated by welding.

Further, in Japanese Laid-Open Patent Publication No. 2-285144, the handrail for main installation and the handrail for temporary installation are combined, and when temporary installation, two types of clamps are attached to the climbing girders of stairs, and at the time of permanent installation, the clamp is ejected. A method of installing a stair handrail that is adjusted and welded to a climbing girder and a handrail support that is composed of two types of clamps and adjustment bolts are described.

[0006]

Conventionally, in consideration of scratches and stains due to collisions of objects during construction work, it is generally clear that the handrails for stairs are for temporary use and for permanent use for final finishing. This is done by dividing and replacing handrails according to the progress of the site.

At this time, the installation of the handrail for main installation to the climbing girder requires a peeping work from the top of the stairs due to its positional relationship, but the peeping work does not improve work efficiency due to poor posture, and If the handrail pitch is small, the work itself becomes impossible.

Further, when the scaffold is used, it is a work of looking up, which is problematic in terms of efficiency, and it costs a lot to assemble and remove the scaffold. Furthermore, when the space between the stairs is small, it may be difficult to secure a working space.

On the other hand, in the one disclosed in Japanese Patent Laid-Open No. 2-285144, the handrail used at the time of temporary installation is used as it is for the permanent installation except for the mounting portion, and there is an advantage that the number of temporary materials can be reduced. However, on the other hand, there is a possibility that the handrail, which was originally for permanent installation, must be replaced due to scratches or stains caused by collision of an object during construction work, which may increase the cost.

The present invention is intended to solve the above-mentioned problems in the prior art, and it is possible to work in a safe posture without temporary scaffolding, and to reduce costs and construction period, and to provide temporary handrails. Is intended to provide.

[0011]

DISCLOSURE OF THE INVENTION A temporary handrail according to the present invention includes a handrail support member having a joint portion for attaching a lower end of a main handrail member to an upper portion, and a joint portion of the handrail support member. On the other hand, an intermediate mounting member that is detachable from and attached to the intermediate mounting member, a temporary handrail joined to the intermediate mounting member, and a temporary handrail member supported by the temporary handrail.

The lower portion of the handrail support member is fixed to the climbing girder of the stairs at the temporary stage, the temporary handrail is attached to the handrail support member via the intermediate mounting member at the temporary stage, and at the final finishing stage. The intermediate installation member and the temporary handrail are removed, and the main installation handrail is attached.

In such a structure, the intermediate mounting member is provided at a temporary stage before mounting the main installation handrail.
It has a function as an adapter for attaching the temporary handrail to the handrail support. The intermediate mounting member and the temporary handrail can be repeatedly diverted.

Further, in the temporary handrail according to claim 2 of the present application, the handrail support member is a joint part on the upper part of the rod-shaped member and is screwed with both the main-installation handrail and the intermediate mounting member. The parts are provided, and the members can be connected in a screw type at both the temporary stage and the final finishing stage.
The work becomes extremely easy.

In addition, in the first aspect, the shape of the handrail support member is not limited to the rod shape, but may be a flat plate shape or a cross-section that changes. The fixing to the climbing girder is not particularly limited, such as fixing with bolts or screws, welding or the like. Further, as for the upper joint portion of the handrail support member, it is sufficient if both the main installation handrail and the intermediate attachment member can be attached,
Not limited to screw type, but not limited to bolts, screws, welding, and the like.

[0016]

The handrail of the stairs is divided into a handrail member as the handrail main body and a handrail supporting the handrail. In the present invention, the conventional handrail is further provided with a handrail support member as an engagement portion with the climbing girder, and The upper handrail is divided into the handrail body, and the handrail support, which is an interface with the climbing girder, is used for both temporary and final finishing.

Therefore, it is possible to directly attach a temporary handrail or a permanent handrail directly from the footboard of the stairs or the landing, and it is possible to suppress the cost increase due to the use of the scaffolding and the like, and to perform highly efficient construction in a safe work posture. Become.

Regarding the handrail main body as a bundle, a temporary one made of a single pipe or the like is often much thicker than a main one. In order to deal with this, in the present invention, an intermediate mounting member having an adapter function is used between the handrail support member and the temporary handrail at the temporary installation stage.

Accordingly, the temporary handrail can be easily replaced with the main handrail for final finishing by removing the intermediate mounting member, and the intermediate mounting member can be used as the main handrail. It also has the function of protecting the joint for attachment.

Further, since the intermediate mounting member can be diverted, the cost does not increase.
