BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing various tools and equipment to a wall of a building by a frame structure or the like, and particularly a mounting structure for absorbing an error and accurately fixing a construction body. Regarding

[0002]

2. Description of the Related Art Conventionally, various structures have been adopted for fixing various tools and devices using a wall. The most common one is to form a flange to hit the wall surface and insert a screw into the hole opened in this, and screw it into the wall, or to open a hole in the back of the tool or the equipment itself and pass the screw through it. Is.

With such a structure, the construction is relatively easy, but since the positions of the holes are fixed, the degree of freedom of attachment of the position of the construction body such as tools and equipment is almost zero. For this reason, it is difficult to perform construction that absorbs errors during installation work.
In order to alleviate this even a little, methods such as making the holes through which screws pass are elongated or increasing the inner diameter are adopted.

As an alternative to such a structure, there is a structure shown in FIG. 7, for example, which can absorb a large construction error. This is a case where the frame 51 using a pipe material is fixed to the wall 50, and a washer 52 that abuts against the wall 50 as a fixing member, a fixture 53 and a screw 54 that fixes the washer 52 to the wall 50, a fixture. 53
This structure is provided with a connector 55 that is constrained by the connector and that connects the frame 51, and a cover 56 that hides a fixed portion to the wall 50. The fixture 53 has a disk-shaped flange 53a formed around a cylindrical portion through which the screw 54 is inserted.
The connector 55 is fixed to the wall 50 side by the screw 54. The coupling tool 55 forms an engagement ring 55b having an opening 55a smaller than the inner diameter of the flange 53a of the fixing tool 53 on the proximal end side, and further, on the front side of this engagement ring 55b, larger than the inner diameter of the flange 53a. An annular groove 55c is provided.

The wall 5 of the frame 51 made of such a member
To fix to 0, first insert the fixing tool 53 into the connecting tool 55, and then pass the screw 54 through this fixing tool 53 to attach the wall 50.
Loosely screw it in and secure these fasteners 53 with the washers 52.
And the connection tool 55 is temporarily fixed to the wall 50. At this time, if the mounting core of the frame 51 does not coincide with the core of the connecting tool 55, the error is absorbed by moving the connecting tool 55 with respect to the fixing tool 53. That is, since a gap is formed around the flange 53a of the fixing tool 53 by the annular groove 55c of the connecting tool 55, the connecting tool 55 is fixed to a certain extent with respect to the fixing tool 53 in the fixed state by utilizing this clearance. Can be moved within range. Since the flange 53a and the annular groove 55c are both circular, the range of this movement is planar when viewed from the front side of the wall 50, up and down, left and right, and a combination thereof. Then, when the position of the connector 55 is fixed, the screw 54 is tightened and fixed, and the frame 51
Is screwed into this connecting tool 55 and the tip thereof is fixed to the fixing tool 5.
The frame 51 is fixed at the correct position by abutting against the flange 53a of No. 3.

[0006]

However, with respect to the fixture 53 whose position is determined by the screw-in position of the screw 54, the connector 55 can only change its position around the center of the fixture 53. That is, assuming that the wall 50 surface is the coordinate plane and the core of the screw 54 is the origin, the coordinate is XY.
The core of the connector 55 can be moved only in the plane, and cannot be moved in the Z-axis direction passing through the origin and orthogonal to the coordinate plane.

As described above, even though the core of the connector 55 can be moved, a mechanism for adjusting the position of the connector 55 in the axial direction thereof is not included. Therefore, for example, in the case of fixing a device or the like including a plurality of frames 51 to the wall 50, the wall 5
If there are irregularities on the surface of 0, an error in the length of the frame 51, and the like, even if the plurality of frames 51 can be fixed to the wall 50 at the same time, distortion occurs. In addition, if the surface is highly uneven, the construction itself becomes difficult, and it is necessary to refinish the wall 50.

The problem to be solved in the present invention is not only to absorb the error around the mounting core of the construction body, but also to absorb the protrusion error in the core direction so that the construction body can be fixed well. To do so.

[0009]

SUMMARY OF THE INVENTION The present invention comprises a restraint which is fixed to a mounting surface such as a wall by a screw which is screwed on, and an error absorber which is connected to the restraint with a degree of freedom around a core. A rear end side is screwed to the error absorbing tool, the position in the axial direction can be changed by the screwing amount, and a connecting tool that connects the construction body to the front end side is screwed to the outer peripheral surface of the connecting tool. And a fastener for restraining the error absorbing tool screwed to the connecting tool.

[0010]

Since the error absorbing tool is free around the core of the restraining tool whose fixing position to the wall is determined, it is possible to absorb the error in the XY directions as in the conventional example. Since the connecting tool integrated with the construction body can be screwed into the error absorbing tool and movable in the axial direction, the position of the connecting tool with respect to the mounting surface can be changed. Therefore, the construction body connected to the wall side by the error absorbing tool and the connecting tool can absorb not only the error in the XY direction but also the error in the distance from the mounting surface.

A similar fixture 1 is also incorporated on the back surface of and fixed to the wall 50 in exactly the same manner.

First, the restraint device 5 is inserted into the error absorbing device 4, the sleeve 5a thereof is inserted into the error absorbing hole 4b, and the washer 3 is passed through the screw 2 through the sleeve 5a and the screw hole 3a.
At the same time, the restraint 5 is firmly fixed to the wall 50. At this time, as shown in the enlarged view of FIG.
a between the error absorbing hole 4b and the flange 5b and the annular groove 4
Since an annular gap is formed between the washer 3 and c, and the flange 4a portion of the error absorber 4 is loosely fitted with a gap between the washer 3 and the flange 5b, the screw 2
The error absorber 4 has a degree of freedom in the XY plane whose origin is the core of.

Next, the female screw 7c of the connector 7 integrated with the valve unit 28 is screwed into the male screw 4d of the error absorber 4. At this time, the protrusion amount of the connector 7 from the wall 50 is adjusted by the screwing amount of the female screw 7c of the connector 7 and the male screw 4d of the error absorber 4, and the position in the Z direction corresponding to the axis of the screw 2 is adjusted. Will be adjusted.

When the position adjustment in the Z direction is completed, the fastener 6 previously screwed into the male screw 7b of the connector 7 is rotated and moved to the right side in FIG. As a result, the right end of the fastener 6 hits the surface of the washer 3. When the fastener 6 is further tightened, one end of the fastener 6 is restrained by the washer 3. Therefore, the fastener 7 is firmly fixed to the error absorber 4 side by the fastener 6 as when the bolts and nuts are tightened. It

In this way, the connector 7 has a degree of freedom in the XY directions with the core of the screw 2 screwed into the wall 50 as the origin, and the amount of protrusion from the wall 50 can be adjusted. Therefore, in the work of fixing the valve unit 28 to the wall, if the protrusion amount from the wall 50 is adjusted so as to match the surrounding pipe, it is easy to use the degree of freedom in the XY directions when connecting to the pipe. Can be plumbed to.

Since the valve unit 28 also rotates during this piping, it is of course possible to adjust the posture of the valve unit 28 up and down when the position adjustment is completed.

By this operation, the valve unit 28 is fixed to the wall 50, and the left valve unit 28 is also attached to the wall 50 by the same operation. And

1b and the connecting pipes 23a and 23b are connected, and further other members are connected, whereby the construction of the shower facility shown in FIGS. 2 and 3 is completed.

In the above construction, the error absorbing tool 4 and the connecting tool 7
It is possible to absorb the error around the core of the connecting tool 7 and the error in the axial direction due to. Therefore, even if the surface of the wall 50 is uneven, the valve unit 28 can be fixed in the correct position and in the correct posture. Particularly, even when the supply pipe 21a and the connecting pipe 23a are connected and integrally fixed to the wall 50 together with these pipes, the member can be attached without distortion and the strength can be properly attached.

In the embodiment, the valve unit in the shower facility is explained as a construction body, but the error absorbing mounting structure of the present invention can be used even when other tools and equipment are fixed to the wall or other structures. Of course, can be applied.

[0031]

According to the present invention, the connector for connecting and fixing the construction body to the mounting surface can be displaced around its core and in the axial direction to absorb the mounting error during construction. Therefore, not only the planar error absorption along the mounting surface but also the distance error from the mounting surface can be absorbed. Therefore, the construction body can be correctly fixed in the correct position even if construction conditions such as unevenness on the surface of the mounting surface are bad. In particular, even in a construction in which a pipe material or the like is assembled and a plurality of points thereof are fixed points to the mounting surface, the pipe material is prevented from being distorted, and a construction body having sufficient strength can be obtained.
