Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a post fixing device for firmly fixing handrails or fence posts provided on concrete bases of stairs, verandas, rooftops, etc.

Conventionally, in order to erect handrail supports on the concrete base of stairs, veeranda, etc., the lower end of the support was welded to reinforcement that had been embedded in the concrete base in advance, or an anchor plate was fixed to the top surface of the concrete base. The method used was to weld a base plate that was pre-attached to the lower end of the support column, but the installation position of the handrail support column was carefully determined in the height and lateral directions to obtain the desired handrail attachment position. On the other hand, in many cases, the reinforcement within the concrete base does not necessarily pass through the installation position of the support column, and the top surface of the concrete base may have some errors, making it difficult to maintain the specified handrail height and placement. In order to accurately respond to this, there was a lot of work to be done on site, such as attaching or adding additional auxiliary reinforcement to the reinforcement within the concrete base and adjusting the height of the anchor plate, which was also complicated.

The present invention is an improvement on the above-mentioned conventional technology, in which a substantially flat anchor plate is fixed to the bottom wall of a mounting hole formed in a concrete base and whose upper side is open. One side of the cylindrical body whose lower end is fixed on the anchor plate is opened on the upper surface, and on both edges of the opening, a clamp integrally formed with a tightening piece with the lower end side as a free end is provided. After adjusting the height of the column by inserting the lower end of the column into the cylindrical body of the clip in the mounting hole, regardless of the slight installation error of the anchor plate or the dimensional error of the column, the height of the column is adjusted. A tightening piece formed facing the edge of the opening is tightened by a tightening element, and is fixed with mortar, etc. filled in the mounting hole, and the support can be adjusted to a predetermined height. At the same time, to provide a support fixing device which can be firmly fixed, can have a beautiful finish without exposing the fixed part to the outside, and can omit complicated on-site work.

The configuration of the present invention will be explained with reference to the embodiments shown in the attached drawings.
1 is a support made of metal material such as steel, aluminum, or brass, and 2 is a substantially flat anchor plate, which is provided in the concrete base of stairs 6, veeranda, etc., and has a mounting hole with an opening on the upper side. It is fixed to the bottom wall of section 7.

When this anchor plate 2 is installed on the stairs 6,
When the stairs 6 are formed, they are temporarily fixed to a temporary frame or frame and concrete is poured and embedded, or concrete is poured and the leg pieces 2a, 2a formed on the lower surface of the anchor plate 2 are embedded before it hardens. It is determined individually.

In this case, a packing such as polystyrene foam is fixed to the upper surface of the anchor plates 1 to 2 to the extent that it can be removed after the concrete base is formed, and by removing this packing, the mounting holes 7 are attached to the concrete base. The anchor plate 2 is formed with an opening on the upper side, and
is fixed to the bottom wall of this mounting hole 7.

3 is provided on the upper surface of the anchor plate 2 and supports 1
One side of the cylindrical body 3a fixed to the upper surface of the anchor plate 2 is opened using a clip for locking the anchor plate 2, and tightening pieces 4, 4, each having a free end at the lower end thereof, are opposed to each other at the edge of the opening. The tightening pieces 4, 4 are provided with a screw-like tightening member 5.
is provided.

To fix the strut 1 to the upper surface of the anchor plate 2, the lower end of the strut 1 is attached to a cylindrical body 3 positioned in the mounting hole 7.
After inserting and positioning the pillar 1, the clamping pieces 4, 4 facing each other are tightened by the clamp 5, and mortar or the like is poured into the mounting hole 7 to fix the lower end of the pillar 1 and the pillar 1. It is used to firmly plant the existing Kutsubu 3.

The present invention has the above-mentioned configuration, in which a substantially flat anchor plate 2 is fixed to the bottom wall of a mounting hole 7 which is formed in the concrete base of a staircase, a veeranda, etc. and has an opening on the upper side. Therefore, the mounting hole 7 can be used as a space for adjusting the height of the support column 1, and the lower end of the cylindrical body 3a, which is open on one side, can be fixed to the upper surface of the anchor plate 2. Since the lower end of the column 1 is inserted, the column 1 can be inserted into the cylindrical body 3a without any extra work such as folding, and errors in molding the concrete base or the column 1 itself can be avoided. The height can be adjusted by moving it up and down according to the dimensional error so that the upper ends of the struts 1 are aligned. This makes it very easy to work on site, and at the same time, the cylindrical body 3
Tightening pieces 4, 4 are placed opposite each other on both edges of the opening of a.
, 4 is tightened to fix the column 1, and the lower end of the column 1 and around the tightening pieces 4, 4 are fixed with mortar etc. filled in the mounting hole 7. By doing so, the fixation of the column 1 becomes even stronger and there is no need to worry about it swinging or coming off.
The fixing part is buried, allowing for a beautiful finish.

In addition, since no welding means is used to install the strut 1, it is possible to install struts made of a variety of materials, such as materials that require relatively long welding work, such as aluminum, or struts coated with synthetic resin or paint with poor heat resistance. It is possible to construct handrails and fences with excellent decorative effects according to various site specifications, regardless of the skill level of the worker.
