た。Buildings built on soft ground often tilt over time due to uneven settlement of the ground and foundation.
In that case, conventionally, most people manually installed hydraulic jacks under the foundation of the building and gradually lifted the foundation from one corner.
The common practice is to insert steel rails into the gaps and lift the building horizontally along with the rails to raise the foundation height. This involves the use of manual labor and some hydraulic jacks and steel rails, which results in poor work efficiency and construction time. It took a long time, and there were also safety issues.

着状況を示す全体斜視図である。An example in which the height adjustment method of the present invention is applied will be described below with reference to the drawings. Fig. 1 is a schematic diagram showing the state in which the height of the foundation of an existing building is adjusted by applying the method of the present invention. Fig. 2 is a side view for explaining the main parts showing how the hydraulic jack is installed on the foundation of Fig. 1, and Fig. 3 is a side view of the installation of the hydraulic jack on the foundation of an existing building when the method shown in Fig. 1 is applied. FIG. 3 is an overall perspective view showing the mounting situation.

In the figure, 8A is the piston rod of hydraulic jack 8, and 8B
is a hydraulic hose.

用して制御されるようになっている。The fixing of the channel 7 to the foundation 6 as shown in FIG. The hydraulic jacks 8 are carried out at as many locations as possible for each foundation 6 as necessary, and these hydraulic jacks 8 are connected to hydraulic units 9 concentrated at r locations via each hydraulic hose 8B using a control panel 10. It is designed to be controlled by

Although the channel 7 fixed to the foundation 6 is used, the hydraulic jack 8 may be attached directly to the foundation 6 of the existing building 2.
次に、第１図に示すように、チャンネル７に対して複数

で常に感知するようにしている。Next, as shown in FIG. 1, a sensor 11 such as a displacement meter is attached to the upper end of the piston rod 8A of a plurality of hydraulic jacks 8 attached to the channel 7.
This sensor 11 detects the water level W in each water pipe 12A of the level gauge 12 disposed at the mounting position of each hydraulic jack 8.
I always try to sense it.

ツキ８を油圧ユニット９により制御するものである。That is, in each hydraulic jack 8, each water pipe 1
Each hydraulic jack 8 is controlled by a hydraulic unit 9 so that the distance l between the water level W in the piston rod 2A and the surface of the base 6, which is the upper end of the piston rod 8A, is kept constant.

調整を完了するのである。According to the above-described height adjustment method of the present invention, all the heights of the foundations 6 of the existing building 2 are set to a certain distance β from the water level W in each water pipe 12A of the spirit level 12.
This results in a levelness of . Therefore, the foundation height adjustment is completed by injecting mortar, cement, or other filler into the gap between the concrete foundation 1 and the foundation 6, or by inserting other fillers.
例えば、基礎１と土台６との隙間にセメントを注入する
場合は、第４図に示すように、基礎１と土台６との隙間

入させる。For example, when injecting cement into the gap between the foundation 1 and the foundation 6, as shown in FIG. Cement 19 is injected through a pipe 18 connected to the tube.
そして、注入したセメント１９の固化をまって前記パネ
ル１６．１７を取り外し、土台高さ調整を完了するので
ある。After the injected cement 19 has solidified, the panels 16 and 17 are removed to complete the foundation height adjustment.

い。If the existing anchor reinforcing bars 20 stop functioning due to this foundation height adjustment, the existing anchor reinforcing bars can be effectively used by connecting new anchor reinforcing bars 22 using the joint pipe 21. It goes without saying that 23 is a washer, 24 is a nand, and the joint pipe 21 has reverse threads on both sides.
