Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a fixture for fixing a plate-like building material such as a ceramic plate or a stone plate to its support.

[0002]

[Prior art]

 As a method of fixing plate-like building materials such as ceramic plates and stone plates (hereinafter simply referred to as building materials) to concrete walls and their supports, a fixing tool such as bolts is erected on the back surface of the building material and the dry fitting method is used. A method of fixing a building material to a support by a construction method or a wet construction method is used.

FIG. 6 (A) shows an example of a dry method. In this example, different types of mounting brackets 104, 106 are attached to the lower end and the upper end of the building material 100 with bolts 102 standing on the back surface of the building material 100. While attaching these to engage them with each other, the mounting metal fitting 106 at the upper end of the building material 100 is connected to the connecting metal fitting 112 fixed to the support body 110 by the anchor bolts 108, so that the building material 100 is attached to the support body 110. I am trying to do it.

On the other hand, FIG. 6 (B) shows an example of a wet method. In this example, the building material 100 is lined up on the form 114, and the fluidized concrete is poured and solidified on the back side of the building material 100. Thus, the bolt 115 protruding against the back surface of the building material 100 is embedded inside the concrete support body 116, and the anchoring action firmly fixes the building material 100 to the support body 116. This construction method is widely used as a construction material pre-attached PC board construction method.

[0005]

[Problems to be solved by the device]

 The bolts 102 and 115 are fixed straight to the back surface of the building material 100, that is, inserted and fixed in the mounting holes 118 formed at right angles to the back surface. If it goes out of 100, the building material 100 may fall off the surfaces of the supports 110 and 116.

[0006]

[Means for Solving the Problems]

 The present invention has been made to solve such a problem. Thus, the invention of the present application is to provide a mounting hole, which is inclined at a predetermined angle with respect to a direction perpendicular to the back surface of the plate-shaped building material, to fix the plate-shaped building material to the support in the mounting hole. A fixture is inserted and fixed (claim 1).

Another invention of the present application is characterized in that a plurality of the inclined mounting holes are provided on the back surface of the plate-like building material, and at least two inclined mounting holes have different inclination directions ( Claim 2).

[0008]

[Action and effect of the device]

 As described above, the invention of claim 1 uses the mounting hole on the back surface of the building material as an inclined hole and inserts and fixes a bolt or other fixing tool therein. Generally, the peeling force from the support that acts on the building material works in the direction perpendicular to the back surface of the building material, but if the mounting hole on the back surface of the building material is made an inclined hole as described above, the pull-out strength of the fixture will be large, and such a fixture Can be prevented from falling out of the building material.

According to a second aspect of the present invention, a plurality of the inclined mounting holes are provided and the inclination directions are different between at least two inclined mounting holes. Even if the pulling force acts in the tilting direction of the mounting hole, it is possible to reliably prevent the fixture from coming off because the other mounting hole has a different tilting direction.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 10 is a plate-like building material such as a ceramic plate or a stone plate, and mounting brackets 12 and 14 are fixed to the back surface by fixing brackets 16. Here, the mounting bracket 12 is fixed to the lower end of the rear surface of the building material 10, and the mounting bracket 14 is fixed to the upper end of the rear surface of the building material 10.

The mounting bracket 12 has an engaged groove 18 formed between the mounting bracket 12 and the back surface of the building material 10, and an upward engaging piece 20 of the mounting bracket 14 is inserted therein and engaged therewith.

The lower mounting member 14 is composed of the engaging piece 20, a fixing piece 22 extending vertically downward, and a horizontal connecting piece 24. The fixing piece 22 attaches to the back surface of the building material 10 by the fixing piece 16. It is fixed.

On the other hand, the connecting piece 14 is connected to a plate-like connecting fitting 26 by bolts 28 and nuts 29, and is attached to the support body 30 via the connecting fitting 26 and the anchor bolt 28.

As shown in FIG. 2, the fixing member 16 is composed of an outer cylindrical member 32 and a driving member 34 driven into the outer cylindrical member 32. The outer cylinder member 32 has an expanding portion 36 that can be expanded and deformed and is inserted into the mounting hole 35 on the back surface of the building material 10, and a main body portion 38 that projects from the back surface of the building material 10.

The outer cylinder member 32 is formed with a slit groove 40 that extends in the axial direction from one end to the other end, and has elasticity based on the slit groove 40.

The expanding portion 36 is further provided with additional slit grooves 42 at appropriate positions in the circumferential direction, and these expanding grooves 36 and 42 allow the expanding portion 36 to be deformed in the expanding direction. ing. The expanded portion 36 has a tapered shape such that the inner peripheral surface and the outer peripheral surface each have a diameter that gradually decreases toward the one end side.

On the other hand, the main body portion 38 is provided with a rib-shaped abutting portion 44 projecting outward in the radial direction at one end on the side of the expanding portion 36, and further, a protrusion having a similar shape is formed at two axially intermediate portions. A projecting portion 46 is provided. Here, the abutting portion 44 serves as a portion that comes into contact with the back surface of the building material 10 via the fittings 12, 14 as shown in FIG. 1, that is, a pressing portion for the fittings 12, 14.

The projection 46 at the intermediate position in the axial direction functions not only as a reinforcing rib, but also by elastically engaging a projection 50 of a driving member 34, which will be described later, to prevent the driving member 34 from coming off together with the projection 50. Is the part that makes up. However, these protrusions 46 and 50 are not always necessary.

In this example, the driving member 34 is a cylindrical member having a substantially uniform thickness except for the protruding portion 50, and has a slit groove 48 extending axially from one end to the other end. On the basis of the slot groove 48, elastic deformation is possible to some extent as a whole. The outer diameter of the driving member 34 is set so as to be closely elastically fitted to the inner peripheral surface of the outer tubular member 32.

On the back surface of the building material 10, the inclined mounting holes 35 are provided at the four corners thereof, and the fixing fittings 16 are inserted and fixed in the respective mounting holes 35. As shown in FIG. 4, these mounting holes 35 are holes whose center line is inclined at a predetermined angle θ with respect to a line which is perpendicular to the back surface of the building material 10.

Therefore, the two mounting holes 35 on the lower end side and the two mounting holes 35 on the upper end side of the building material 10 have different inclination directions, and the two lower mounting holes 35 have the same direction, The two mounting holes 35 on the upper end side are inclined in the same direction.

In FIG. 1, the mounting holes 35 and the fixing fittings 16 inserted and fixed in the mounting holes 35 are inclined toward the center of the building material 10, respectively, but as shown in FIG. It is also possible to point the outside of the building material 10 or to the outside in the radiation direction centered on the center of the building material 10.

Furthermore, it is also possible to make the inclination directions of the mounting holes 35 completely different from each other. Here, the inclination angle θ of each mounting hole 35 is preferably 5 ° or more, and more preferably in the range of 15 ° to 25 °.

Next, in this example, a fixing procedure of the fixing metal fitting 16 and the mounting metal fittings 12 and 14, and a mounting procedure of the building material 10 to the support body 30 will be described. In this example, the expanded portion 36 of the outer tubular member 32 is provided with a through hole of the mounting bracket 12, 14 (this through hole is usually a circular hole having an inner diameter smaller than the outer diameter of the contact portion 44 of the outer tubular member 32 or It is an elongated hole whose inner diameter in the lateral direction is smaller than the outer diameter of the contact portion 44.) and is inserted into the mounting hole 35 on the back surface of the building material 10.

Then, with the abutting portion 44 of the outer tubular member 32 in contact with the back surfaces of the mounting members 12 and 14, the driving member 34 is tapped into the outer tubular member 32 and slid in the axial direction. Type while moving.

At this time, the driving member 34 is elastically fitted to the inner peripheral surface of the outer cylindrical member 32 under a predetermined frictional force, and in this state, the inner peripheral surface of the outer cylindrical member 32 is slid in the axial direction while the outer cylindrical member 32 is slid in the axial direction. It is deeply inserted inside. Then, in the process in which the tip portion thereof penetrates the inside of the expanding portion 36, the expanding portion 36 is expanded and deformed by the cam action of the inner peripheral taper surface, and the outer peripheral surface of the inner peripheral surface of the mounting hole 35 on the rear surface of the building material 10. It is strongly pressed against the surface.

As a result, the fixing metal fitting 16 itself including the outer cylinder member 32 and the driving member 34 is fixed to the back surface of the building material 10, and at the same time, the plate-shaped mounting metal fittings 12 and 14 are firmly fixed to the back surface of the building material 10. .

In this way, the mounting brackets 12 and 14 are fixed to the back surface of the building material 10 in advance, and when the building material 10 is installed, the mounting brackets 12 and 14 engage with each other, connect with the connecting bracket 26, and connect the connecting bracket 26. By fixing the building material 10 to the support 30, the building material 10 is attached to the support 30.

The above is an example of the case where the building material 10 is dry-processed, but the present invention is also applicable to the case where the building material 10 is wet-processed. FIG. 5 shows an example thereof. In this example, the fixing metal fitting 16 is embedded in the support body 52 made of concrete, and has a function of fixing the building material 10 by the anchor effect.

In this example, the outer cylinder member 32 is inserted into the mounting hole 35 on the back surface of the building material 10 so that the contact portion 44 directly contacts the back surface of the building material 10, and in that state, the driving member 34 is moved to the outer cylinder. The fixture 16 is fixed to the building material 10 by driving it into the member 32. Then, by arranging the building materials 10 and pouring fluidized concrete on the back surface side to solidify the concrete, the building material 10 can be attached to the surface of the support body 52 made of concrete. This example is suitable for applying the construction material 10 to a PC board.

At this time, if the mounting hole 35 and the fixture 16 are inclined, the peeling strength of the building material 10 from the support body 52 becomes large, and the building material 10 is reliably prevented from peeling. The advantage is obtained.

Although the embodiment of the present invention has been described in detail above, this is merely an example. For example, the fixing metal fitting 16 is merely an example, and it is possible to use a bolt that is conventionally used as a fixing tool and fix the bolt to the back surface of the building material 10 by the same method as the conventional one.

Further, an adhesive may be injected between the fixing metal fitting 16 and the inner surface of the mounting hole 35 to fix them together, or a fixing metal fitting composed of ordinary pins may be bonded with an adhesive. It is also possible to adhesively fix it to the mounting hole 35.

Further, in the above example, all of the mounting holes 35 provided on the rear surface of the building material 10 are inclined holes, but only one or two of them are inclined holes and the other are straight in the direction perpendicular to the rear surface of the building material. In some cases, it is possible to form the hole.

Further, the present invention can be applied when the building material 10 is attached by a construction method different from that of the above example, and further when the plate-shaped building material made of a material other than a ceramic plate or a stone plate is installed. The present invention can be configured in a form in which various modifications are made based on the knowledge of those skilled in the art without departing from the gist of the present invention.
