Description

DETAILED DESCRIPTION OF THE INVENTION The present invention aims to provide a jack-up device for a house or the like having a novel configuration.

If you are building a building with a low water level and are subject to damage such as flooding above the floor during floods, or if you are building an underground garage in an existing house, we will jack up the entire foundation of the building.

It is necessary to hold this for a certain period of time, remove the existing foundation, form a new foundation with a higher height, and then install the foundation and building on this new foundation. Conventionally, during such work, mechanical jacks have been used to raise each bar one by one while checking the level. but.

This takes time and effort, and the reality is that only a highly skilled person can do it.

The present invention aims to fully solve this problem, and one embodiment thereof will be described in detail below with reference to the drawings.

1 is a jack-up device of the first invention.

And its configuration consists of the YII foundation 2m in the Y direction and the
Kf on foundation 2 consisting of xgA foundation 2B in direction: platform 3
In the building 4, corner posts 5 are installed at the four outer corners of the foundation 2, and the corner posts 5 are parallel to the -I foundation part 2B and rise and fall with respect to the corner posts 5. Attach the main beam 6 freely.

On the upper surface of the main beam 6, there is a pair of bases located on the lower surface of the foundation 3. The secondary auxiliary beams 7 are mounted, and the auxiliary beams 12 are placed so that the intermediate part of the main beam 6 is located on the lower surface of the X side of the foundation 3, and the pair of Yll auxiliary beams 7 are mounted on the Yll auxiliary beams 7. The configuration of the jack-up device of the second invention is such that the structure of the jack-up device of the second invention is between the two Y-side auxiliary beam units 7m parallel to each other and the two carrier units 7m, which are parallel to the device 1. The corner support 5 is constructed with two rail bodies 5 erected in parallel.

Below the rail body 5m, there is a hydraulic cylinder 8 and a mechanical safety follow-up jack in the longitudinal direction of the rail body.

The upper end of 9 is connected to the lower surface of the main beam 6, and
The hydraulic cylinder 8 is configured to be operated by a liquid level detection device 10 such as an electrode rod type installed on the main beam 6 and a hydraulic solenoid valve.

The configuration of the jack-up device of the third invention is that in the device 1, the corner support 5 has a shape 9 in which two rail bodies 5 are erected in parallel! In addition, small holes 5" for raising and lowering are bored in the wall surface of the rail body at predetermined intervals, and a hydraulic cylinder 8 and a mechanical safety follower jack to be attached to the rail body are installed. The lower end of -9 is connected and supported by pins 8A and 9 which are inserted into and removed from the small holes 5°, and the upper ends of the hydraulic cylinder 8 and jack 9 are supported by bearings that protrude 1ffK below the main beam 6. Bins 8B and 9 for 6mm
They are detachably connected at B.

Further, the hydraulic cylinder 8 is configured to be operated by a liquid level detection device 10 such as an electrode rod type installed on the main beam 6 and a hydraulic solenoid valve 4P+.

Therefore, the above main beam 6IY @ auxiliary beam 7. Since the auxiliary beams 12 are arranged so as to be located on the lower surface of the foundation 3,
This beam 6, 7.12 is installed at the installation position of the beam 6, 7.
A notch 2x into which 7.12 can be inserted is formed. Furthermore, the auxiliary beam 12 is connected to the Y-side auxiliary beam 7 so as to be on the same level. The above explanation is based on the case where the foundation 2 has a Yll foundation 2m and an However, in this case, a pair of Ygl auxiliary beams 7 and a supporting beam 7B are appropriately employed around this partition wall, and an appropriate number of auxiliary beams 12 are also installed. This means that if the size of the cassowary is large (when Todoroki is inside the building), the intermediate main beam 13, which has the same structure as the main beam 6 above, will be placed parallel to the main beam 6 supported by the corner supports 5. Naturally, in this case, a support similar to the corner support 5 will be installed as the intermediate support 14.

For Tsuki-9, oil motor, air motor 9
The power from 0 is transmitted to a threaded rod 9H via a speed change gear 9D, and a cylindrical body 9ν that can be raised and lowered as the rod 9E rotates is screwed onto this rod 9B. Furthermore, @llllft of the liquid level detection device 10 is the main beam 6.
It is designed to control the elevation while maintaining the horizontal position. The IIIM consists of a main device 10A that moves up and down with respect to the ground, and a sub-device 100 connected to the main device 10 by a pipe 10B. They are fixed to the main beam 6 with bands 100 or the like so as to be located on the left and right sides of the I lid 10m. Therefore, the above-mentioned main device 10m is connected to the support 10 installed on the ground G and LK.
A container 10F for storing 10 volumes of liquid is movably movable up and down in D, and the upper surface of this container 10F has a static pressure port 10G.
0G is fitted. Furthermore, the above-mentioned sub-device 100 is constructed by fitting a lid 10G having a static pressure port 10G' onto a container 10 that stores a liquid 10H, and this lid has a liquid level. , the first fi pole rod 1aJ having a high height with respect to L and the #I2 electrode rod 10y having a low height are attached. In addition, the main device 1
To raise and lower the f10mm, screw the threaded portion 10mm of the main device 10mm onto a threaded rod 10D held parallel to the support IDD, and when the threaded rod 10D is rotated, the main device moves with the support 10D as a guide. So, to explain the operation of the above device 1a, when the main device is raised to a desired height by rotating one threaded rod, the water level of the liquid 101 rises and the liquid in the sub device 100 rises. 10H is also on the same level.
↑rise. As the liquid 10H rises, the lower ends of the second electrode rods 10J and 10.7' come into contact with the liquid 10HK.

As a result, 1. A current flows between the second electrode rods and generates a rising signal, which causes the solenoid pulp to flow and each hydraulic cylinder 8 to extend, causing the main beam 6 to rise. 20 With the rise of main beam 6 lff1l! ! 100 also rises.

When the sub-device 100 rises, the liquid level of the liquid 10B falls - as a result, the Iil electrode rod 10J is removed from the liquid level. As a result, electrical conduction is interrupted and the main beam 6 stops rising.In the case of the main beam 6 falling, the first electrode rod 10. T is not in contact with the liquid surface, and when j [2 electrode rods 10J are in contact with each other, a reverse signal with no electrical conduction causes the solenoid pulp to open, lowering the pressure in the hydraulic cylinder and lowering the main beam 6.

Due to this descent, the liquid level rose and the first. The two electrode rods come into contact with the liquid surface and become electrically conductive. This reverse signal sends a close signal to the solenoid pulp to stop the drop in oil pressure, and this action is repeated to perform a rising or falling action.

The present invention has a main beam 6 which is constructed as described above.
In order to raise the object to a predetermined height, the object is raised together with the base, and this raised state is maintained for a period of time, as shown in Figure 820.

The foundation 2 is removed and a new foundation 2D of the desired height is formed as shown in FIG. After that, the main beam is lowered onto the new foundation 2D.◎This new foundation 2D also has a depression 2D' into which the lowered main beam will fit, and.

B. When raising and lowering the main beam 6, the hydraulic cylinder 8 and the safety tracking jack 9 were used together.

When the main beam is raised, the hydraulic cylinder 8 mainly acts, and the safety follow-up jack 9 follows the extension of the hydraulic cylinder 8. 1. Safety can be ensured when trouble occurs with the hydraulic cylinder. This also applies when it is maintained for a certain period of time for foundation work. Incidentally, the above-mentioned jack 9 is designed to have an output far lower than the load.

The operation of these hydraulic cylinders 8 and jacks 9 will be explained as follows. Figures 11 and 12
As shown in the figure, the hydraulic cylinder 8 and jack 9 are in a contracted state 1aK, and as shown in FIG. Next.

The hydraulic cylinder 8 in the contracted state is located in the small hole 5° on the upper blade.
kK bin 8mm, 8N? Install it with After that, remove jack 9 and pin 9m and 9B. As a result, the main beam 6 is busy being supported by the hydraulic cylinder 8. After summing this state, Jyatsuki-9 is in the contracted state 11 [L-TEHIN9
9Bt-, and install it parallel to the above-mentioned jack 9. The mounting position is such that the main beam 6 is raised by the expansion action of the eleventh under 8.

0, and the hydraulic cylinder 8 is equipped with a liquid level detection device 1.
Since the hydraulic cylinders 110 are arranged in series, the gravity load on each hydraulic cylinder is not constant, but it can be raised and lowered while maintaining the horizontal position 1aK.As a result, damage to the building can be avoided.

This is a useful invention with many advantages.
