Description

[Detailed description of the invention] The present invention relates to a device for attaching supports for balconies, terraces, fences, guardrails, etc. to the foundation, and particularly to a device for attaching supports when renovating old handrails for balconies, fences, etc. .

Conventionally, various types of support mounting devices of this type are known.

For example, a column mounting device is known in which an anchor is inserted into the lower end of the column and fixed with a screw, and the anchor is fixed to a mounting bracket fixed to the upper surface of a foundation.

However, with this structure, the screws that secure the anchor to the pillar are exposed to the outside, resulting in a poor appearance.

Therefore, as shown in Japanese Utility Model Application Publication No. 56-121821, an upward U-shaped mounting bracket was fixed to the top surface of the foundation.
A plate-shaped anchor fixed to the lower end of the column is fixed to the bottom plate of the mounting bracket, and a pair of left and right holding brackets that contact the left and right walls of the column are installed across the front and back plates of the mounting bracket to secure the column. A mounting device has been proposed in which the fixing means is difficult to visually see from the outside.

However, with this structure, the fixing means can be seen from the left and right, and the appearance is not very good.
Since the anchor is fixed only to the lower end of the column, the attachment strength of the anchor is weakened, and the attachment strength of the column is also weakened.

The present invention was devised in view of the above circumstances, and its purpose is to improve the external appearance by making the screws that secure the anchor and the support column invisible from the outside, and to provide a support installation device that increases the anchor installation strength. The goal is to provide the following.
