Abstract

PURPOSE:To achieve a higher working efficiency by a method wherein a staff with a fitting section is fitted into a height adjusting section provided on a base arranged on the setting surface and the adjusting section is moved together with the staff to match the staff with a specified height and then, a column or the like is placed on the base. CONSTITUTION:A plurality of channel-shaped bases 3 are arranged on a floor rail 1 laid on a concrete slag 2 at a specified interval. Then, an adjust bolt 4 is screwed vertically on the top of the base 3 and the height thereof is adjusted by turning it clockwise or counterclockwise. Then, a staff 5 provided with a three- way scale 6 on the top thereof while having a fitting section 7 at the bottom thereof is errected on the head of the adjust bolt 4 in such a manner as to disable relative rotation as well as upward movement thereof. One worker visually observes the three-way scale 6 with a level 8 while the other worker sets the adjust bolt 4 at a specified height by turning it clockwise or counterclockwise. Then, the staff is taken off and a column (not illustrated) or the like is placed on the rail 1 and the adjust bolt 4. This enables the saving of labor along a higher working efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for adjusting the height of a pillar, etc., and a leveling rod used for adjusting the height.

In recent years, there has been a trend in hospitals, offices, etc. to divide rooms with movable partition walls to effectively utilize indoor space.

In constructing this partition wall, it is not possible to directly install a partition wall on an uneven floor surface, so for example, a channel steel base is fixed on an uneven concrete slab, which is a type of floor surface. An adjustable pole that is screwed onto the base and stands upright!・The height of the foundation was adjusted by rotating it, and then columns were erected on the adjustment bolts, and partition walls were installed between the columns.

By the way, this conventional method for adjusting the height of columns, etc. is to superimpose a leveling rod with a height of 11 steps on the adjustment bolt, and adjust the height of this leveling rod [1 step] to 411 points using a surveying instrument such as a level.
1. After setting the level, lower the leveling rod from the azimuth I bolt 7, turn the adjustment bolt to adjust the height,
I had to repeat the process of adjusting the leveling rod again to the standard position of the level by setting it vertically above the bar and adjusting it to the specified height.

However, this conventional method requires three workers: one to operate the leveling rod, one to adjust the adjustment bolt, and one to visually check the level, resulting in the problem of requiring a large number of people to complete the work. In addition, there is a problem in that work efficiency decreases as the staff must be repeatedly hung on the adjustment bolt to measure the height. It was difficult to vertically install the leveling rod with accuracy, which caused the problem of reduced adjustment accuracy.

The present invention has been developed in view of the above circumstances, and aims to reduce the number of workers required for height adjustment work of columns, etc., and to improve work efficiency.
Moreover, it is an object of the present invention to provide a method for adjusting the height of a pillar, etc., which can improve the accuracy of height adjustment, and a leveling rod used for the height adjustment.

The structure of the method for adjusting the height of pillars, etc. according to the present invention in order to achieve this objective is to place a base on the installation surface, and install a height adjustment part screwed into the base, which is positioned relative to the adjustment part. Unable to rotate and-
By fitting a leveling rod with a fitting part that cannot be moved in either direction, and in this state, rotating the adjusting part together with the leveling staff and moving the adjusting part downward by 1 L, the leveling rod can be adjusted. The gist is to align a predetermined scale with a reference position, and then place a pillar or the like on the adjustment section in place of the leveling rod.

Also, the configuration of the leveling rod used for height adjustment is as above.

The gist is that a fitting part is provided at the lower part of the leveling rod, and the height adjusting part of the base having the height adjusting part screwed in so as to be movable downwardly is fitted in such a manner that the height adjusting part is not relatively rotatable and cannot be movable upwardly. That is.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a schematic diagram illustrating a method for adjusting the height of columns, etc. according to an embodiment of the present invention, and numeral 1 in the figure indicates a floor rail. This floor rail l is made of a thin steel plate in the shape of a long channel, and is fixed to the uneven surface of the concrete slab 1 with curl plugs, which will be described later, and serves as a mounting surface for pillars, etc. . However, this installation surface may be the surface of the concrete slab 2, unless the floor rail 1 is provided.

Reference numeral 3 denotes a base, and this base 3 is made of metal in the shape of an ice cube, and a plurality of parts are spaced apart from each other at predetermined intervals to support the floor rail i.
-It is fixed upside down.

Reference numeral 4 is an adjustment port which is a height adjustment part, and this adjustment port]-4 is screwed and vertically installed on one L surface of the base 3, and is rotated in either the left or right direction to adjust the height. It is now possible to adjust the height and level of pillars, etc.

Further, the height of the adjustment port 4 is adjusted by screwing it up and down, and a metric fine thread with a finer pitch is more suitable than an inch size uniform thread with a coarse pinch. In addition, the height adjustment part may be formed by fixing a mounting surface part to the adjustment bolt part.

Next, the adjustment bolt 4 according to an embodiment of the present invention
Explain how to adjust the height. First, the leveling rod 5 is vertically installed on the head of the adjustment bolt 4. A three-sided scale 6 on which a height scale is engraved is provided on the upper part of the leveling rod 5, and a fitting part 7, which will be described later, is formed in the lower part.
is fitted with an adjustable port. Then, while a worker visually observes the three-sided scale 6 on the surveying instrument, ie, level 8, installed on the concrete slab 2'', another worker rotates both the level rod and the adjusting port 4 to the left or right. Adjust the height of the adjust port 4 and set the adjust port 4 to a predetermined height.

After this height adjustment, the floor rail l and adjustment port 4 are attached to the column 9 or wall panel lO as shown in FIG.
to complete the construction of the partition wall. Note that the pillars 9 and wall panels 10 are covered with surface materials 11 and 11 as shown in FIG.
It is not limited to those with a gypsum board acid backing material 12.12 inside, but can be modified in various ways, such as those with a surface material stretched only on one side, or those with a door or glass window formed as a part. Of course.

Next, the leveling rod 5 used for the height adjustment will be explained. As shown in FIGS. 1 and 3, this leveling rod 5 has a three-sided scale 6 on the second part of a long pipe, and a fitting part 7 on the lower part.
It has been established. Since this three-sided scale 6 is intended to enable height graduations to be measured from any direction, it may be a cylindrical scale with height marks engraved over the entire circumference.

The fitting portion 7 is formed by closing the upper part of a fitting collar 13 of a wrench fixed to the lower inner circumferential surface of the leveling rod 5 with a disc-shaped stopper 14. The head of the head is fitted in such a way that it cannot relatively rotate and cannot move upwardly. Note that the leveling rod 5 and the fitting part 7 are not limited to those described above, and for example, as shown in FIG.
It is possible to form the fitting part 14 into a solid cylindrical shape by recessing the lower part thereof, and use the -1- wall surface as the stopper surface 15. Furthermore, the fitting flange 13 is not limited to the shape of a spanner, but may be a fitting flange of a box wrench or an end plug that integrates the fitting flange and a stopper, in other words, the shape of the fitting flange 13 is not limited to the shape of a spanner. It may be any material that can be fitted together irreversibly. Further, reference numeral 16 in FIG. 3 is a curl plug, and this curl plug 16 is embedded in the concrete slab 2 so that the floor rail l is fixed onto the concrete slab 2 via the curl plug 16.

The method for adjusting the height of a pillar, etc. according to the present invention as described above and the leveling rod used for the height adjustment reduce the number of workers required for height adjustment work compared to the conventional three workers. The number of workers can be reduced to two: a worker and a worker who operates the leveling rod 5. Also, the height adjustment work itself does not require raising and lowering the leveling rod to Adjustment Port 4 as many times as in the past.
The height can be adjusted by simply rotating the three-way scale 6 at level 8 in either the left or right direction while measuring the scale 6, which greatly reduces the time required for the work. Can be done.

Moreover, during the height adjustment work, there is no need to raise and lower the leveling rod many times as in the conventional method, so the leveling rod 5 is always hung on the adjustment port 41 in a constant state, and the verticality of the leveling rod 5 changes. This prevents the fitting state between the fitting portion 7 and the adjustment port 4 from changing, and improves the accuracy of height adjustment.

As described above, the present invention is a highly practical invention that is highly effective and can be easily implemented.
