FIG. 1 shows a jack 4 for supporting a foundation beam 2 of a building on a floating foundation 5 and a measuring means for measuring the level of the foundation beam 2 in the vicinity of the jack 4.

The foundation beam 2 is supported on the floating foundation 5 by the short columns 6. The jack 4 is housed inside the short column 6 and lifts the foundation beam 2 according to the operation. Further, in order to hold the foundation beam 2 lifted by the jack 4 at that position, a filler 18 is interposed between the short column 6 and the floating foundation 5, and anchor bolts 19 protruding from the floating foundation 5 tighten these.

The level measuring means includes a displacement manometer 1 that is fixed to the foundation beam 2 in proximity to the jack 4 and a reference manometer 3 that is fixed to a predetermined position of the foundation beam 2 through a communication pipe 9. A water injection valve 16 and a drain valve 17 are connected to each.

The reference manometer 3 is configured so that the float accommodated inside the cylinder rises to a predetermined position together with the water surface inside the cylinder so that the electrical contacts provided in the cylinder are brought into conduction. Output to.

Further, as shown in FIG. 2, the displacement manometer 1 guides water to the inside of the cylinder 7 from a communication pipe 9 connected to the bottom of the cylinder 7, and a float 8 accommodated inside the cylinder 7 responds to this water level. A rod 10 that is coupled to the float 8 projects upward from the cylinder 7 and is coupled to a core 11, and a coil 12 is arranged around the core 11 so as to be vertically displaced.

A current is applied to the coil 12 from the oscillator 13, and the AC output from the coil 12 that changes according to the displacement position of the core 11 is converted into a DC output by the rectifier circuit 14 and output to the controller 15 as a water level signal.

An indicator 21 is attached to each displacement manometer 1. The indicator 21 is connected to the controller 15 by a signal circuit,
As shown in FIG. 2, a display unit 22 showing numerically the difference between each part level of the foundation beam 2 measured by the output signal of the displacement manometer 1 and a jack operation target value to be described later, which is visually displayed. A bar graph 24, a display section 23 showing the direction of the jack operation required for level correction, a display lamp 25 having three kinds of green, yellow, and red lamps visually showing the level correction state, and a voice instruction for jack operation. The speaker 26 shown in FIG.

On the other hand, the controller 15 is composed of a microcomputer, etc., and turns on / off the input signal from the reference manometer 3.
Based on, the opening / closing control of the water injection valve 16 and the drainage valve 17 is performed so that the water surface level in the reference manometer 3 is kept constant.

In this way, the controller 15 maintains the water level of the reference manometer 3 at a constant level, and each displacement manometer 1
The level of each part of the foundation beam 2 is obtained from the water level signal input from the. In addition, the controller 15 is preset with the level that each part of the foundation beam 2 should originally be, and the controller 15 calculates the difference between these levels and the level obtained as the target value for level correction, and calculates the level. The result is displayed on the display unit 22 and the bar graph 24 of the indicator 21. In addition,
This display is continuously performed during the level correction work by operating the jack 4.

Further, the indicator lamp 25 of the indicator 21 is turned on according to the change in the difference between the target value for level correction and the current level, and the same information is output as a sound through the speaker 26.

 Next, the operation will be described.

When measuring and correcting the level fluctuation amount, when the operator inputs a measurement start signal to the controller 15, the controller 15 closes the drain valve 17 and opens the water injection valve 16.
As a result, water is injected into the displacement manometer 1 and the reference manometer 3 through the communication pipe 9, and when the water surface in the reference manometer 3 reaches a predetermined level, the signal input from the reference manometer 3 to the controller 15 is turned on. After that, the controller 15 controls the opening and closing of the water injection valve 16 and the drain valve 17 so that the reference manometer 3 maintains this water surface level.

On the other hand, the water level signals are continuously input from each displacement manometer 1 to the controller 15, and the controller 15 inputs the water level signals from the reference manometer 3 while maintaining the predetermined water surface level to the respective parts of the foundation beam 2. , And the difference between these values and the target value for level correction set inside beforehand is calculated. Then, the calculation result is displayed in real time on the display unit 22, the bar graph 24 and the lamp 25 of the indicator 21 attached to each displacement manometer 1.
At the same time, the direction of the jack operation required for level correction is determined from the calculation result, and the determination result is displayed on the display unit 23.

The worker operates each jack 4 based on these displays to correct the level fluctuation. The operation of the jack 4 is performed by removing the nut screwed with the anchor bolt 19.

In that case, the worker knows the direction of the jack operation from the display of the display unit 23, and can further confirm the level fluctuation accompanying the jack operation in real time on the bar graph 24 of the display device 21, so that the level can be corrected accurately. be able to.

When the difference between the detected level of the foundation beam 2 and the corrected target value is large, the green lamp of the indicator lamp 25 lights up. During this time, the jack 4 is operated at a fast pace to approach the target level. The operation pace is reduced when the yellow lamp indicating is turned on, and the operation of the jack 4 is stopped together with the lighting of the red lamp indicating that the target level has been reached, whereby the level correction work is efficiently completed in a short time.

It should be noted that the change in the level due to the operation of the jack 4 can be confirmed by the sound from the speaker 26.

After that, the gap between the short column 6 and the floating foundation 5 is adjusted by the filler 18, and the nut is fastened to the anchor bolt 19.

After the correction work is completed, the operator inputs a measurement end signal to the controller 15, whereby the controller 15 closes the water injection valve 16 and opens the drain valve 17, and the displacement manometer 1 and the reference manometer 3 are emptied via the communication pipe 9. To

Although the indicator 21 is attached to the displacement manometer 1 in this embodiment, the indicator 21 may be arranged anywhere as long as it is easy to see during the operation of the jack 4.
