Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a handrail and a construction method for installing the same, and more specifically to a handrail comprising a plurality of brackets fixed to a wall surface formed of panel material with fixing means, and a capstone supported by these brackets. and its installation are related to construction methods.

[Conventional technology]

Generally, handrails are horizontally installed with a cap supported by multiple brackets that have flange-like attachment parts that are fixed to the wall, and the gap between the wall and the cap is set to a certain extent that prevents hands from getting caught. The dimensions are set. In addition, in order to attach the handrail configured as described above to a wall surface, first, with the mounting part of the bracket in contact with the wall surface at an appropriate interval, fixing screws etc. that pass through this mounting part are inserted. The commonly used method is to screw the bracket into the wall and then support the cap at the tip of the bracket. Furthermore, in recent years, it has become common for walls, especially in high-rise buildings, to be formed of lightweight panel materials, and similar handrails are attached to the walls formed in this way.

[Problem to be solved by the invention]

However, in the above-mentioned conventional handrail, the bracket is fixed by screwing a fixing screw or the like into the wall through the mounting part with the mounting part of the bracket in contact with the wall surface. This protrudes from the wall, and as a result, not only does it look unsightly, but the distance between the cap and the wall and the distance between the cap and the mounting part are set to the above-mentioned constant dimensions, so the cap protrudes from the wall more than necessary. There is a problem in that it protrudes and narrows the space in hallways and stairs. Moreover,
With this structure, since it is directly fixed to a wall such as a panel at the site, there is a problem in that it takes a lot of labor and time to install. In addition, panels are often made of lightweight yet fragile panel materials, making drilling holes on-site difficult to process, and when screwing the panels on-site, the paint on the panel surface may peel off! Second, the periphery will be damaged, so it will be necessary to repaint or finish the locking part. Furthermore, panel materials generally have a structure in which a metal plate is stretched over the surface of a noncombustible panel substrate such as gypsum board, so it is not strong enough and brackets cannot be directly fixed to the panel. There are disadvantages such as the need to use reinforcing members. This invention was made in view of the above circumstances, and the panel material l
In the wall formed by this method, the mounting part of the bracket is fixed without protruding from the wall surface, widening the effective space of corridors, stairs, etc., and the handrail can be easily and firmly attached. Its installation is intended to provide a construction method.

[Means to solve the problem]

In order to achieve the above object, the handrail of the present invention is based on a handrail consisting of a plurality of brackets fixed to a wall surface with fixing means and a capstone supported by the brackets, and the mounting portion of the bracket is attached to the wall surface. The fixing means is formed into a rectangular shape that is inserted into the joint between the panel materials constituting the panel material, and the fixing means is attached to the support column through a mounting hole that penetrates from the joint portion toward the space of the support column for holding the panel material. The anchor includes an anchor installed inside the anchor, and a screw member screwed to the anchor through the mounting portion and the mounting hole. In this invention, the attachment portion of the bracket may be any rectangular shape that is inserted into the joint between the panel materials, but preferably, the attachment portion of the bracket may be any rectangular shape that is inserted into the joint between the panel materials. It is preferable that a groove is formed to surround the bent piece of the surface plate of the panel material, and a recess for accommodating the head of the screw member is formed on the surface of the mounting portion. In this case, the screw member may be attached to the attachment portion at one location, but it is preferable to provide recesses for attachment of the screw member at two locations above and below the attachment portion. In addition, in order to install the above-mentioned handrail, the method of installing the handrail of the present invention includes first drilling a mounting hole that penetrates the support for holding the panel material from the joint between the panel materials and opens into the support.
a second step of penetrating the mounting hole and installing the anchor in the support; and screwing the screw member to the anchor through the mounting portion of the bracket inserted into the joint and the mounting hole. The process consists of a third step of supporting the Kasagi with the bracket, and a fourth step of supporting the Kasagi with the bracket. To install the handrail of this invention, it is necessary to attach a joint cover to the joint part after fixing the bracket to the wall surface due to the construction method, but in order to make the installation of the joint cover easy and reliable, a joint cover is attached to the mounting part of the bracket. It is desirable to have a means of ensuring that

[Created by]

With the above configuration, the bracket can be mounted at the joint between the panel materials by drilling a mounting hole that penetrates the column for holding the panel material and opens into the space I in the column. After the anchor is installed in the space inside the column through the mounting hole, the bracket is fixed to the wall by screwing the screw member to the anchor through the mounting part of the bracket that is inserted into the joint part. . The installation is then completed by supporting the Kasagi with the bracket. Since the mounting part of the fixed bracket is inserted into the joint part as described above, the mounting part of the bracket does not protrude from the wall surface, and the distance between the wall surface and the cap can be set to a predetermined dimension. At the same time, spaces such as hallways and stairs can be used effectively. Further, by providing a recess in the mounting portion to accommodate the head of the screw member, it is possible to further eliminate any protrusion from the wall surface.
