Problems to be Solved by the Invention 4-49318
14 (a), the upper and lower ends of the holder 51 are elastically deformed by the bolts 50 so as to move to the right side in FIG. generate. For this reason, although the holder 51 uses an elastically deformable metal plate, this elasticity easily causes instability after fixing the exterior plate 60, and thus the exterior plate 60.
There is a limit to the firm fixation of.

Further, since the holder 51 is pulled toward the building by the bolt 50, the corners at the upper and lower ends of the holder 51 hit the inner wall of the engaging groove 61 as shown in FIG. 14 (b). Therefore, the holder 51 is locally engaged with the engaging groove 61.
After the engaging groove 61 is scraped off, the exterior plate 6
The concentration of stress on the remaining sharp edges of zero increases the likelihood of fracture at these sharp edges.

In the one disclosed in Japanese Utility Model Laid-Open No. 4-62733, as shown in FIG. 15, the engaging portion 52 acts so as to pull the meat on the back surface side from the engaging groove 62 to the outside. For this reason, if the mounting strength becomes excessive, stress concentrates in the engagement groove,
As shown in the figure, there is a risk of breakage from the end portion of the engagement groove 62. Further, since the engaging portion 52 is formed as a pair of members whose front end side is bent and the front end of the bent portion is tapered, the workability in fitting into the engagement groove 62 is poor and there are many construction problems.

Further, in the one disclosed in Japanese Utility Model Publication No. 5-2726, the tip of the holder is inserted into the groove provided on the small surface and is engaged with and held by the groove. There is a possibility that the binding force will be concentrated and the groove portion will be broken as well. Further, although the backing material is filled for stable holding, there is a problem that the posture of the holder is disturbed by the flow-in pressure of the backing material itself at the time of filling.

As described above, in the conventional construction of the exterior plate, partial breakage of the exterior plate and other obstacles due to stress concentration by the holder on the exterior plate remain.

A problem to be solved in the present invention is a fixture which can be securely fixed and held in its correct position without breaking the plate-like building material and can be improved in workability, and a plate-like building material using the same. Is to provide a mounting structure.

1 to 4 show an embodiment of a mounting structure for a plate-like building material using the fixing device of the invention according to claims 1 to 3 of the present application. FIG. 1 shows the fixing of an exterior plate to a PC plate. FIG. 3 is an exploded perspective view showing a mounting member for the.

In this example, the fixture 1 is used as the attachment member.
And a bolt 2. The fixture 1 is made of a metal plate having an appropriate thickness and capable of elastic deformation, and is manufactured by bending so as to open a surface facing an exterior plate (described later). Then, on the open end side, the fixture 1
Is formed with a pair of engaging pieces 1a obliquely protruding outward in the width direction, and the seating surface 1b extends from the engaging pieces 1a to the end in the width direction. Further, a female screw hole 1 for screwing the bolt 1 is provided on one end side in the width direction of the fixture 1.
c is provided.

Both end portions in the width direction of the fixture 1 may have a shape orthogonal to the portion forming the upper surface in FIG. 1, but are curved so as to bulge slightly inward as shown in FIG. 2 (a). The wall surface may be formed. Then, when the bolt 2 is screwed into the female screw hole 1c and the tip thereof is abutted against the wall on the other end side, the bolt 2 is further screwed in as shown in (b) of the same figure. Then, the fixture 2 is deformed so as to be expanded in the width direction. By utilizing the deformation of the fixture 1 by the operation of the bolt 2 as described above, it is possible to freely change the interval between the pair of engagement pieces 1a connected to the exterior plate side.

FIG. 3 is a vertical cross-sectional view of a main part showing an example in which a tile is used as an exterior plate and fixed to a PC plate by a fixture 2.

An engaging groove 41 into which the engaging piece 1a is inserted is formed in advance on the back surface of the tile 40, and the fixture 1 having the bolt 2 integrated therein is attached to the tile 40. At the time of this attachment, the distance between the lower ends of the engagement pieces 1a in the figure is made to substantially match the distance between the cutout portions of the two engagement grooves 41, and then the bolt 2 is moved to the left side in the figure. Rotate to move. Thereby, the engagement groove 4
The engaging piece 1a gradually enters the inside of 1, and the seating surface 1b can be seated on the back surface of the tile 40 as illustrated.

After mounting the fixture 1, the bolt 2
Is finely adjusted to move further to the left, and the V-shaped outer surface portion between the engaging piece 1a and the seating surface 1b is firmly joined to the inner wall of the engaging groove 41. At this time, since the fixing tool 1 is deformed so as to expand in the width direction of the fixing tool 1 and in the moving direction of the bolt 2 having an axis substantially parallel to the back surface of the tile 40, the upper surface of the engaging piece 1a in the drawing is the engaging groove 41. The seating surface 1b abuts against the back surface of the tile 40 at the same time as it comes into close contact with the inner wall of the tile.
Therefore, for example, the engaging piece 1a does not locally hit a part of the engaging groove 41, and the tile 40 can be prevented from breaking by avoiding concentration of stress. Also,
Although the stress concentrates on the remaining portion of the tile 40 in which the engaging groove 41 is shaved, the stress is offset by being pressed by the seating surface 1b.

Further, since the fixing tool 1 is elastically deformed in the width direction directly by the rotation of the bolt 2, the engaging force between the engaging piece 1a and the engaging groove 41 can be strengthened, and the fixing tool is fixed. Two
It is held stable without shaking.

Further, by rotating the bolt 2, the distance between the engagement pieces 1a can be greatly changed.
For example, in the conventional example shown in FIG.
Although the deformation of the holder 51 due to the above is utilized, the magnitude of the elastic deformation can be changed only by the distance corresponding to the distance that the plate 50a can move in the holder 51. On the other hand, the engaging piece 1a can change its position in a large range as shown in FIG. 2, which facilitates insertion into the engaging groove 41 and absorbs a manufacturing error of the engaging groove 41. It is possible to install it.

Fixture 1 attached in this way
After being set in a mold together with the tile 40, the is incorporated as an anchor material for a PC board 42 formed by placing a backing material such as concrete.

Incidentally, in order to prevent the distortion of the bolt 2 and stabilize it so that the turning operation is speeded up, a cap 2a may be provided at the tip of the bolt 2 as shown in FIG. The cap 2a is rotatable about the axis of the bolt 2 and stops when the cap 2a hits the wall of the fixture 1, while the bolt 2 maintains its freedom of rotation. Can be easily turned to work.

FIG. 4 shows an example in which the looseness of the bolt 2 and the stability of its posture are improved.

This is a washer 2b and a spring washer 2c on the surface of the fixture 1 on the side where the bolt 2 is inserted.
And a lock nut 2d are arranged respectively, and a pair of guide pieces 1c are provided from the end of the fixture 1 where the tip of the bolt 2 faces. These guide pieces 1c are formed so as to sandwich the tip of the bolt 2 in the drawing, and the inclination of the axis of the bolt 2 in the direction orthogonal to the drawing can be eliminated.

By providing such a guide piece 1c, the bolt 2 can be reliably advanced and retracted in a direction in which both widthwise walls of the fixture 1 are expanded and contracted, and the engagement groove 41 of the engagement piece 1a. It can be securely inserted and locked. Further, by providing the lock nut 2d and the like, the positional deviation of the fixture 1 after being attached to the tile 40 is prevented.

FIGS. 5 and 6 show an embodiment showing a mounting structure of a fixture and a plate-like building material of the invention according to claim 4 of the present application, FIG. 5 is an exploded perspective view of members, and FIG. 6 is a tile PC The longitudinal cross-sectional view of the principal part when attached to a board is shown.

In this example, as a fixture for the exterior plate, a joint 3 connected to the tile 40, a restraint 4 covering the joint 3, and bolts 5a and nuts 5b connecting them.
It has.

The joining tool 3 is formed by bending a metal plate having an elastically deformable thickness and is formed into a substantially convex shape. In the drawing, an engaging piece having a cross-sectional shape similar to that of the previous example is formed at the lower end. 3a and a seating surface 3b. A connecting seat 3c protruding upward is provided in the central portion, and a through hole 3d for inserting the bolt 5a is formed in the center of the upper end of the connecting seat 3c.

The connecting seat 3c is formed as a metal plate having vertical walls 3c-1 and 3c-2 formed in a "concave" shape. The vertical walls 3c-1 and 3c-2 are connected to each other. The spacing should be slightly longer on the lower end side than on the upper end side.

The constraining tool 4 covers the connecting seat 3c of the jointing tool 3 from above and is integrally connected. The constraining wall overlaps with the vertical walls 3c-1 and 3c-2 of the connecting seat 3c at both ends in the width direction. Four
a and 4b are formed, and a bolt 5a is formed at the center of the upper end.
The through hole 4c is opened. The distance between the inner walls of the restraint walls 4a and 4b is determined by the vertical walls 3c-1 and 3c-2.
Shall be approximately equal to or slightly longer than the distance between the upper ends of the. Further, the restraint tool 4 has at least a rigidity that can correct the elastic deformation of the joining tool 3, and uses a material that is less likely to be elastically deformed than the joining tool 3.

The attachment of the connector 3 to the tile 40 is shown in FIG.
In, the connector 3 is moved in the direction orthogonal to the drawing to insert the engagement piece 3 a into the engagement groove 41. In addition, the engagement piece 3

After that, when the restraint tool 4 is put on the connecting seat 3c, the vertical wall 3c of the connecting seat 3c having a hem-spreading shape.
It is deformed so that the distance between the lower end side portions of -1, 3c-2 is narrowed. As a result, the upper surface of the engagement piece 3a comes into close contact with the inner wall of the engagement groove 41, and the same seating surface 3b as in the previous example can be joined in a surface contact state without stress concentration.

Then, the bolt 5a is passed through the through holes 3d and 4c and the nut 5b is screwed together with the washer 5c and the like, whereby the restraint tool 4 can be connected to the connector 3.

Here, the distance between the vertical walls 3c-1 and 3c-2 can be adjusted by changing the screwing amount of the bolt 5a and the nut 5b. That is, in the state of FIG. 6, since the restraint tool 4 is connected to the joint tool 3 at the lower limit position, the space between the vertical walls 3c-1 and 3c-2 is the smallest. On the other hand, if the restraint tool 4 is connected by the bolts 5a and the nuts 5b above the state shown in the drawing, the space between the vertical walls 3c-1 and 3c-2 will be slightly widened.
Therefore, the distance between the pair of engagement pieces 3a can be changed by adjusting the screwing amount of the bolt 5a and the nut 5b, and the engagement force for the engagement groove 41 can be set and the engagement groove 41 can be set. It is possible to mount the product while absorbing manufacturing errors.

a, a nut 8b and a washer 8c are integrally connected. At this time, the pressing portion 7a is seated on the back surface of the tile 40, and the bolt 8a tends to move upward by being screwed with the nut 8b. Therefore, the joining tool 6 receives a load toward the upper side in FIG. 8, and the upper surface of the engaging piece 6a abuts against the inner wall of the engaging groove 41 so that the tile 41 and the joining tool 6 are restrained and fixed to each other.

In this mounting structure, a force is generated by which the engaging piece 6a pushes the meat portion of the V-shaped tile 40 above the engaging groove 41 toward the back surface side. On the other hand, the pressing portion 7a of the protector 7 covers the rear surface of the tile 40 in the vicinity of the engaging groove 41, and the pressing force of the pressing portion 7a for pressing the tile 40 is the engaging piece 6a. Is balanced with the force that pushes the inner wall of the engagement groove 41. Therefore, the load of the engagement piece 6a that tries to push the meat of the V-shaped cross section to the outside is offset, and the breakage of this portion is prevented.

The anchor member 9 is not necessary for the construction of the building shown in FIG. 9, and it is possible to attach only the members shown in FIG.

A fixture 71 is attached to the wall 70 of the building by anchor bolts 71a.
A holding metal fitting 72 is connected to 1 by bolts and nuts 72a. The front end portion of the holding metal fitting 72 is abutted against the connecting seat 7b and integrally joined by the bolt 8a and the nut 8b.
