JPH01151618A - Jig for correction of creeping-up of structure - Google Patents

Abstract

PURPOSE:To make correction of creeping-up of a structure built in a soft ground possible, by a method wherein adjusting members in cylindrical shape are put over the upper end of supporting piles driven into the earth, and an external thread provided over the outer periphery of the adjusting members are screw- fitted to the supporting members of a structure. CONSTITUTION:Adjusting members 1, in a cylindrical shape and having external thread 3 on their outer periphery, are put over the upper end of supporting piles 12 driven into the earth. And a foundation 13 with a footing member 14 is erected with supporting-members 5 being screw-fitted to the adjusting members 1 with threaded pipes 7. When the ground 15 subsides further and creeping-up of a structure occurs, the surface of that ground is turned up. Then a rod-shaped tool is inserted between the protrusions 4 protruded upward from the top of the adjusting members 1. By turning the adjusting members 1 in a direction of loosening the screw, the supporting members 5 are lowered relative to the adjusting members 1 and the foundation 13 and the structure are lowered together and the creeping-up can be corrected.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a jig for correcting when a building such as a house has climbed relative to the ground.

Conventional technology When constructing a building such as a house on soft ground, first, support piles are driven to the supporting layer of this ground, and a foundation is built on top of these support piles to support the building so that it does not sink. It is. Therefore, the building itself will not sink because it is supported by the supporting layer of the ground via the support piles, but in the case of soft ground, the ground surface will fall and the building will appear to have climbed up. This can lead to complaints from building owners due to the condition and the unsightly appearance. Conventionally, there has been no means to simply and easily correct when a relative overhang occurs in a building, and there has been an inconvenience that such a frame cannot be appropriately dealt with.

The present invention provides a correction jig that can easily correct such an overhang of a building.

Means for Solving the Problems In order to achieve the above object, the present invention provides a support pile (12) that is driven into the soil and is held at the upper end of the support pile (12) so as not to move downward. The adjustment member (1) is rotatably attached to the
6) is buried in the foundation (13) or is in contact with the bottom of the foundation (13) to support the foundation (13).
), and these adjustment members (1) and support members (5
) are connected to each other via threaded portions (3) and (8) so that the support member (5) can be moved up and down by the rotational operation.

Function: If the ground around the building sinks and the building is relatively lifted up, rotate the adjustment member (1) to move the support member (5) that supports the foundation downward. The correction is made by moving and lowering the entire building.

Examples Next, the structure of this invention will be explained based on examples.
FIG. 2 shows the correction jig of the present invention. In the figure, (1), as shown in Figure 1, is a cylindrical adjustment member with a ceiling (2) at its upper end, and a male screw (3) is formed on its outer periphery. ing. In addition, on the upper surface of the ceiling part (2), there are four projections (4) (
4)... are fixed at equal intervals in the circumferential direction.

(5) consists of a support plate (6) and its support plate (
6) and a threaded pipe (7) which is fixedly fixed to the center part so as to protrude upward from the center part of the support pipe (7). The screw (3) is screwed in to form a female screw (8). Furthermore, a through hole (9) is formed in the support plate (6) as shown in FIG. 1, corresponding to the hollow part of the screw pipe (7). The support plate (6) has embedded members (10) (10
)... is provided to protrude upward. In this embodiment, a bolt is used as the embedded member (10).

The method for installing the above-mentioned correction jig will be explained based on Fig. 1. First, the support piles (12) (12) are driven into the soil, and the support members (5) Fit the threaded pipe (7) onto the outside.

At this time, the adjustment member (1) is screwed into the threaded pipe (7), and the ceiling part (2) is brought into contact with the upper end surface of the support pile (12), and the adjustment member (1) and the support member (5) is supported in a hanging manner. Next, the support plate (6)
The foundation (13) is constructed such that the lower surface of the footing portion (14) of the foundation (13) is in contact with the upper surface of the foundation (13). At this time, the buried member (10) is buried in the footing portion (14), and the support member (5) and the foundation (13) are integrated. Further, the upper end portion of the threaded pipe (7) of the support member (5) projects upward from the footing portion (14). After that, the upper part of the footing (14) is placed on a predetermined ground surface (
15) and bury the adjustment member (1).

In this state, if the ground (15) sinks and the building rises up, a part of the ground surface (15) is dug up and the adjustment member (1) is moved upward as shown in Figure 3. A rod-shaped tool (16) is inserted between the protruding protrusions (4), and the adjusting member (1) is inserted between the male screw (3) and the female screw (8) through the protrusion (4). Rotate in the direction to loosen the screw. As a result, the support member (5) is adjusted to the adjustment member (1).
), and along with this, the foundation (13)
Since the building also descends by that amount, the ground surface (15)
It is possible to correct the rise of the entire building according to the subsidence of the building. At that time, if the relationship between the rotation angle of the protrusions (4) (4)... and the movement stroke of the support member (5) is determined in advance, the amount of correction can be calculated by measuring the rotation angle of the protrusion (4). can be managed.

In the above embodiment, the adjustment member (1) has a ceiling portion (
2) is held against the upper end surface of the support pile (12) so as not to move downward, but this may be done by other means, for example, by attaching a flange to the outer periphery of the support pile (12). Install the adjusting member (1) to the flange.
Various methods can be considered, such as adding . In addition, the support member (
5) connects the support plate (6) to the footing portion (14).
) and may be integrated with the foundation (13).

Effects of the Invention As described above, according to the present invention, even if the ground around the building sinks and a relative upheaval phenomenon occurs in the entire building, by rotating the adjustment member, Because the building can be lowered according to the amount of subsidence,
There is an advantage that such correction of overflow can be performed easily and in a short time.
