Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail attachment jig for attaching a handrail to a veranda such as a detached house or an apartment.

[0002]

2. Description of the Related Art Generally, when a veranda is installed in a house or a condominium, conventionally, a hole is made in a concrete base in advance, a base of a handrail member is inserted into the hole, and a large number of wedges are driven around the hole to adjust the levelness and the position. After adjusting and fixing, it is carried out by filling with an adhesive or fixing by electric welding.

[0003]

However, in the method in which the handrail is fixed by hammering in the wedges and fixing them, the base of the handrail is bent until it solidifies due to external conditions. However, there was a problem that the handrail could not be attached accurately due to eccentricity or eccentricity.
Also in the case of electric welding, there is a similar problem that the base of the handrail is bent or eccentric during the welding work, and the handrail cannot be attached accurately. Therefore, in any case, there is a problem that a high degree of skill is required to attach the handrail accurately and accurately. Therefore, in spite of the demand for a technique for attaching a handrail accurately and accurately without requiring a high degree of skill, the reality is that there is still no drastic solution.

In order to solve the above-mentioned problems, the present invention is used when a hole is made in a base such as concrete and the base of a handrail member is inserted into the hole to fill an adhesive agent or fix by electric welding. An object of the present invention is to provide a handrail mounting jig that can be mounted accurately and accurately without requiring skill.

[0005]

In order to solve the above-mentioned problems, the present invention provides an opening through which a slide bar of a clamp member for holding a handrail mounting base can be inserted, and a fastening metal fitting is attached to the side surface thereof. While configuring a guide member to be mounted on the clamp member, on the side surface of the guide member,
The means is to provide a stretchable holding piece for holding the vertical frame of the handrail member. Therefore, when attaching the handrail to a base such as concrete, it is possible to firmly support the vertical frame of the handrail member via the clamp, until it is solidified after filling the adhesive, or The vertical frame of the handrail is not bent or eccentric while being fixed by electric welding, and the handrail can be attached with high precision and accuracy.

[0006] Yet another invention is to provide the guide member,
The means is that it is slidably and detachably attached to the holding portion of the L-shaped clamp. Therefore, when attaching the handrail to a base such as concrete, it is possible to firmly support the vertical frame of the handrail member through the clamp, or until it solidifies after filling the adhesive, or The vertical frame of the handrail is not bent or eccentric while being fixed by electric welding, and the handrail can be attached with high precision and accuracy. Moreover, since it is slidable and detachable, it is possible to sufficiently deal with changes in the dimensions of the base such as concrete, and depending on the work form, only the L-shaped clamp can be used for other work. It is also possible.

Still another aspect of the present invention is that an L-shaped arm for supporting the horizontal frame of the handrail member from below is detachably attached to the holding portion of the L-shaped clamp. Therefore, if the means for holding the vertical frame of the handrail member and the means for supporting the horizontal frame of the present invention from below are used together, the handrail can be attached accurately in both the horizontal and vertical directions. You can

Still another aspect of the present invention is to provide a guide member for mounting a slide bar of a clamp member which holds a handrail mounting base, into which an opening can be inserted, and a fastening metal fitting is attached to the side surface of the clamp member to be mounted on the clamp member. At the same time, the guide member is provided with, on its side surface, an expandable and contractible holding piece for holding the vertical frame of the handrail member and an L-shaped arm for supporting the lateral frame of the handrail member from below. . Therefore, since the means for holding the vertical frame of the handrail member and the means for supporting the horizontal frame from below are integrally configured, when the handrail is attached to a base such as concrete, a clamp is used to attach it. While firmly supporting the vertical frame of the handrail member, it is also possible to adjust the horizontalness of the horizontal frame at the same time, so it is necessary to fill the adhesive and then solidify it or fix it by electric welding. There is no bending or eccentricity of the vertical frame or the horizontal frame of the handrail, and it is possible to mount the handrail with higher accuracy in both horizontal and vertical directions with one jig. Like

Still another aspect of the invention is that the guide member is slidably and detachably attached to the holding portion of the L-shaped clamp. Therefore, when a handrail is attached to a base such as concrete, it is possible to firmly support the vertical frame of the handrail member via the clamp and also adjust the horizontalness of the horizontal frame of the handrail member. Therefore, the vertical frame and horizontal frame of the handrail do not bend or become eccentric until it is solidified after filling with the adhesive or fixed by electric welding. It becomes possible to attach the handrail with higher precision and accuracy in any of the vertical directions. Moreover, since it is slidable and detachable, it is possible to sufficiently deal with changes in the dimensions of the base such as concrete, and depending on the work form, only the L-shaped clamp can be used for other work. It is also possible.
