Abstract

PURPOSE:To enable a support body hanged down to be finely adjusted in level, and make it easy to finely adjust a base in level by providing rails within angles supported by a plurality of setting legs acting as a board carry-in and installation tool at the time of plant construction, and letting the rails be so constituted as to be moved up and down with a bolt rotated, which is loaded over a dolly. CONSTITUTION:When a base is set, which is used to fix a board over a floor surface as a foundation at the time of board installation, and when levels are to be established, and when an installation level is adjusted, the installation tool for the base is transported via a bolt 24 first. A dolly equipped with rollers 23 is moved back and forth. When the dolly is run, signals from the outside are received by a control box 18, and s shaft 15 is rotated by driving a motor 13 in response to signals received. The rotation of the shaft 15 allows the bolt 24 to be rotated via a pinion 16 and a worm gear, the bolt 24 is moved up and down as the bolt is rotated, and as a result, the installation level for the base supported by the lower end section of the bolt is thereby adjusted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel and channel base (hereinafter simply referred to as "base") installation work requiring level fine adjustment.

[0002]

2. Description of the Related Art The base used for fixing the board to the floor as a foundation for installing the board is not always horizontal when setting it. It is necessary to adjust the installation level.

Conventionally, the method of setting the installation level is to place spacers at a plurality of places on the floor surface of the box, and then place the channel base on the spacers. Since the bottom surface is not horizontal, the top surface of the channel base is not horizontal to the regular floor surface, so measure the level from the top surface of the base at one point installed in multiple places and use that level as the reference. To do. 3 remaining
Regarding the points, the upper surface of the base is leveled out by inserting and removing spacers so as to reach the reference level.

Upon completion of leveling, the side surface of the base is spot-welded to the reinforcing bar and welded, and then the entire leveling is performed again, and mortar is filled and fixed to the floor surface. Among the series of operations, especially the time is spent for leveling out the base, and the working method uses spacers, but it is very difficult to make fine adjustments in millimeters by taking out and putting in the spacers.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a device capable of easily performing fine adjustment of a base level simply by rotating a bolt.

[0006]

According to the present invention, the rotation of a bolt whose level can be finely adjusted is used, and the support is raised and lowered with four-point support to facilitate leveling.

[0007]

Since the fine adjustment of the base level can be facilitated, the work efficiency can be improved.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1, 3 and 4 are plan, front and side views of a carriage for carrying a base installation tool. It can be moved back and forth by the roller 23.
The left and right are connected by a shaft 19 and are fixed on the carriage by a shaft receiver 20.

In this cart, the control box 18 receives a signal from the outside and drives the motor 13 to rotate the shaft 15. Further, the rotation of the worm 24 is controlled by rotating the worm gear 14 via the pinion 16. The bolt 24 and the base are connected to each other by using a bolt hole that is fixed when the board is installed, and the bolt, the worm gear, and the pinion can be easily changed so that the diameter of the bolt hole can be changed. .

FIG. 2 shows a state in which the bolt is mounted on the carriage.

An example of using the tool of the present invention is shown in FIGS.

The base 30 is temporarily welded to the bar 31 when it is installed on the floor without a box. At this time, since the floor surface is not always horizontal, the base upper surface is leveled. Must be done. Therefore, the above-mentioned installation trolley is used, but two trolleys are required for one pedestal, and a plurality of pedestals must be prepared in order to prevent distortion of the long base. In FIGS. 5 and 6, the base is supported by a total of four carriages (bolts). Further, since the bolt 24 is provided with the cap nut 32 temporarily attached by welding on the ventral side of the base, it can be easily taken out even if the mortar is filled in the box-extracted place after the positioning is performed. it can.

The base supported by four points measures the distance from the upper surface of the base to the uppermost point of the pedestal at one point using a surveying instrument, and the level is used as a reference. The remaining three points can be raised and lowered by externally controlling the rotation of the bolt 24 to match the reference level described above, and the level can be finely adjusted to facilitate leveling.

In addition to this, it is also possible to make the gantry large and perform it by itself, and it is also possible to manually adjust the elevation level of the bolt 24.

[0016]

The present invention eliminates the need for spacers as compared with the conventional method, which reduces the number of workers and improves work efficiency.
