Further, the support of the structure is ensured, and the support work can be speeded up and the displacement of the structure can be easily prevented.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a structure minute adjustment support base 1 according to the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the structure micro-adjustment support base 1 includes a base 2, a table 3 for supporting the structure, a lower support 4 erected from the base 2, and the lower support 4. Is provided at the position corresponding to the upper column 5 from the table 3.

The base 2 and the table are flat plates made of steel and having a required thickness. Further, the upper and lower supports are, for example,
It is a cylindrical steel pipe, and is integrated with the base 2 and the table 3 by means such as welding. In addition, the length of the upper and lower columns 4 and 5 is equal to each other or one of them is longer,
It is set arbitrarily according to the work space.

Further, a reinforcing plate (triangular plate) 6 and a reinforcing plate (rectangular) 7 are provided on each of the upper and lower columns 4 and 5. A bolt 8 is provided between the lower support 4 and the upper support 5 so as to be removably inserted into a steel pipe as the support. A screw groove is formed on the outer peripheral surface of the bolt 8. For example, as shown in FIG. 3B, a hole is formed at a position corresponding to the lower support 4 of the base 2 and the bolt 8 is extended downward in the hole. It may be a bolt 8a. As a result, the amount of extension in the vertical direction increases.

As shown in FIGS. 4A and 4B,
The same length as the struts 4 and 5, or the upper side (upper strut 5
a) is to be a structure minute adjustment support base 1a having a longer length.

Nuts 9 and 10 are double-threaded on the bolt 8. As shown in FIGS. 2 to 4, the nuts 9 and 10 are provided between the upper and lower supports 4 and 5.

The nuts 9 and 10 provided on each of the columns are provided between the lower column 4 and the upper column 5.
This is a double nut for holding the height position of the table 3.

In order to use the structure micro-adjustment support base 1 formed in this way, for example, when supporting the structure to be settled and corrected, the base 2 and the reinforcing plates 6 and 7 support and reinforce the support. A light weight state in which three members for assembling the support members 4, the upper support members 5 supported and reinforced by the table 3 and the reinforcing plates 6, 7 and the bolts 8 and the nuts 9, 10 are formed in a factory in advance and disassembled. At the site.

Then, a pressure-resistant plate is laid in a narrow working space excavated under the structure or the foundation, and the base 2 and the lower support 4 are placed thereon. Next, the bolt 8 and the nuts 9 and 10 are mounted on the lower support 4 of the base.

While the table 3 and the upper support 5 are placed on the lower support 4 and the upper part of the bolt 8 is included in the steel pipe,
Install. At this time, since the working space is narrow, the bolt 8
The head (upper part) of the lower support 4 is not projected long from the upper end of the lower support 4.

Thereafter, a jack 11 is provided on the upper surface of the base 2.
The table 11 is lifted by temporarily applying pressure to the jack 11 as shown in FIG. Then, since the upper support 5 also rises at the same time, the nut 9 is tightened with a tightening jig such as a monkey or a spanner until the nut 9 contacts the lower end surface of the upper support 5. In this way, a sufficient supporting force is transmitted through the table 3 to make the structure minute adjustment support base 1 a temporary support base.

In the structure minute adjustment support table 1,
For example, it is possible to adjust the height positions of the four upper columns 5 so as to flexibly cope with the case where the inclination direction of the structure is not constant.

As another embodiment of the structure micro-adjustment support base according to the present invention, as shown in FIGS. 5 (b) and 5 (c), a bolt 8 is elongated vertically to form bolts 8a and 8b. There is proposed a structure in which support bases 16 and 16a are provided under the base 2. As the amount of expansion and contraction increases, it can be installed at a higher position by the support base.

Further, the steel pipes of the upper and lower supports are made to have diameters which are in sliding contact with each other, and are slid up and down.
As shown in FIG. 6, the structure micro-adjustment support base 1b can be slid up and down with steel angles 12, 13 to slide up and down. For example, as shown in FIGS. 7 to 9, a reinforcing plate 14 is laid on top of steel angles 12 erected at the four corners of the base 2, and the angles are connected to each other and fixed firmly. Further, a reinforcing plate 15 is laterally mounted below a steel angle 13 vertically suspended from four corners of the table 3 and is similarly fixed.

This slide type structure micro-adjustment support base 1
In the case of b, after the table 3 is raised by the jack 11, the steel pipe or the steel angle after sliding is welded at that position to fix the position. With the structure minute adjustment support 1b, the same operation and effect as those of the structure minute adjustment support 1 and 1a can be obtained.
