CONSTITUTION:Double nuts 14 are screwed to each of a plurality of anchor bolts 13 implanted to a concrete foundation 12. A column mounting plate 15 is installed to the anchor bolts 13, and the mounting height of the plate 15 is adjusted by the upper nuts of the double nuts 14 while the plate 15 is locked by the lower nuts. A base 11 is placed on the plate 15, and clamped and fixed by nuts 16. The plate 15 is omitted, and the base 11 can also be clamped directly. Accordingly, the installation work can be simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting height adjusting structure for entrance columns installed in entrance porch or the like.

[0002]

2. Description of the Related Art In general, an entrance pole is one in which a column base is mounted and fixed on a concrete foundation whose height has already been set, and the mounting height cannot be adjusted. Therefore, in an industrial production house in which the entrance pole is factory-manufactured and the height dimension is fixed, it is extremely difficult to place the height of the concrete foundation in advance with high accuracy.

As a structure for improving the height of the concrete foundation with high accuracy, there is a structure as described in Japanese Utility Model Publication No. 48-14866. In this conventional technique, anchor bolts are planted on the upper surface of a concrete base so that a part of the anchor bolt protrudes from the upper surface to form a base. A through hole is provided at three or more places of the projecting piece of the frame body to which one piece is fixed, and a bolt longer than the height of the frame body is screwed so that the frame body is supported by the bolt to form an adjustment frame body.
The adjusting frame is placed on the upper surface of the base so that the protruding portion of the anchor bolt enters the adjusting frame, and the coagulating material is flowed into the adjusting frame and solidified. According to this prior art, by moving the bolt 5 forward and backward, the upper edge portion of the adjustment frame body B is made to have the same height, and the surface formed by the upper edge portion is horizontally adjusted so that the rear condensation material 6 can be adjusted. When the upper edge portion of B is solidified by inflow, the upper surface of the condensing material 6 which becomes the upper surface of the column base has a desired height.

[0004]

However, in the prior art, in the installation site, the height of the adjusting frame is adjusted according to the length of the entrance pole, and then the coagulating material is flowed into the adjusting frame and solidified. Since the desired foundation height is obtained in, the construction is complicated, and the construction date and time is large.

An object of the present invention is to make it possible to easily and quickly adjust the mounting height of an entrance pole on a concrete foundation at an installation site.

[0006]

According to the present invention as set forth in claim 1, in an installation height adjusting structure of an entrance pole for mounting and fixing a column base to an anchor bolt planted in a concrete foundation, a plurality of anchor bolts are provided. A double nut is screwed onto each of them, and a column base is supported on the double nut.

According to a second aspect of the present invention, in addition to the first aspect of the present invention, a plurality of insertion holes provided in the column mounting plate are inserted into each anchor bolt, and the column mounting plate is attached to each anchor. It is configured such that it is supported on the double nut screwed to the bolt, and the column base is mounted and fixed on the column mounting plate.

[0008]

According to the present invention as set forth in claim 1, the following effects are obtained. Each double nut, which serves as a support member for the column base, is screwed on each anchor bolt to be moved up and down. Therefore, by supporting the column base on each double nut and screwing the double nut, the entire entrance pillar can be moved up and down, and the entrance pillar can be set at a desired mounting height position. Then, after setting the entrance pole at a desired height position, each double nut is locked, and the pillar base is fixed on the double nut.

According to the second aspect of the present invention, there are the following effects. The pillar mounting plate, which serves as the mounting and fixing surface of the pillar base, is moved up and down by screwing a double nut screwed on each anchor bolt. Therefore, by placing the column base on the column mounting plate and moving the column mounting plate up and down by screwing the above-mentioned double nut, the whole of the entrance column can be moved up and down, and the entrance column can be set at a desired mounting height position. Can be set. Then, after setting the entrance pillar at a desired height position, each double nut is locked, and the pillar base is fixed to the pillar mounting plate on the double nut.

[0010]

FIG. 1 is a schematic view showing an embodiment of the present invention.

The entrance pole 10 has a flange-shaped pillar base 11 fixed to two anchor bolts 13 planted in a concrete foundation 12. At this time, the concrete foundation 12 is already placed before the installation of the entrance pillar 10.

However, each anchor bolt 13 has a double nut 14 screwed thereto.

An insertion hole 15A provided in the pillar mounting plate 15 is inserted into each anchor bolt 13, and the pillar mounting plate 15 is supported on the double nut 14 screwed to each anchor bolt 13. It is like this.

In the entrance pole 10, the insertion holes 11A provided in the pillar base 11 are inserted into the anchor bolts 13, and the pillar bases 11 are fixed by the nuts 16 screwed to the anchor bolts 13. Mount on 15 and fix.

The procedure for adjusting the mounting height of the entrance pole 10 will be described below.

(1) The pillar base 11 of the entrance pillar 10 is placed on the pillar mounting plate 15.

(2) The vertical level and horizontal level of the column mounting plate 15 are adjusted by screwing the double nuts 14 screwed onto the anchor bolts 13. Thereby, the entrance pillar 1 supported on the pillar mounting plate 15
0 is moved up and down as a whole to set the entrance pole 10 at a desired mounting height position.

(3) The double nuts 14 are locked and the nuts 16 are fastened to fix the column base 11 on the column mounting plate 15.

The operation of this embodiment will be described below.

The column mounting plate 15 serving as the mounting and fixing surface of the column base 11 is vertically moved by screwing the double nuts 14 screwed to the anchor bolts 13. Therefore, the pillar base 11 is placed on the pillar mounting plate 15, and the pillar mounting plate 15 is moved up and down by screwing the double nut 14 described above, whereby
The whole 0 can be moved up and down, and the entrance pole 10 can be set at a desired mounting height position. Then, after setting the entrance pole 10 at a desired height position, each double nut 14 is locked, and the pillar base 11 is fixed to the pillar mounting plate 15 on the double nuts 14.

Therefore, the mounting height of the entrance pole 10 on the concrete foundation 12 can be easily and quickly adjusted at the installation site.

In the practice of the present invention, the column mounting plate 15 is not necessarily used, the column base 11 of the entrance column 10 is directly supported on each double nut 14, and each double nut 14 and the nut 16 are used. Alternatively, the column base 11 may be sandwiched and fixed.

[0023]

As described above, according to the present invention, the mounting height of the entrance pole on the concrete foundation can be easily and quickly adjusted at the installation site.
