Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to a joining jig used for forming accessory tiles.

(Conventional Joining Jig) FIG. 4 is a perspective view showing a conventional joining jig 2. The joining jig 2 is used to form an accessory tile by joining two flat plate-shaped tiles 1 and 1 (shown by a chain double-dashed line) in a state of being bent in a V shape. , 1 was used as a holder for each piece. That is, the structure of the joining jig 2 was such that a total of eight round bars 4, 4, ... Having different lengths were erected on the base 3. And, the tip end surface of the round bar 4 is
It was formed so as to have a downward slope toward the central line portion of the base 3. As described above, the reason why the plurality of round bars 4, 4, ... Are used to support the tile 1 is that the tile 1 is almost always warped in the plane direction due to its manufacture. there were. It should be noted that the conventional joining jig 2 includes, in addition to the above-mentioned round bar 4 erected, a plurality of elastic protrusions (not shown) provided on an inclined plate surface. It was

In order to form the accessory tile by using the joining jig 2 configured as described above, first, for each tile 1 and 1, the side portions 1a and 1a to be joined are finished into an acute angle, and the acute angle side portion is formed. Tiles 1 and 1 are round bar 4,4,
… Place it on top. Then, an adhesive such as an epoxy resin is applied to the butted portion and the curing is waited for.

(Problems to be Solved by the Invention) The conventional joining jig 2 is very convenient for joining tiles 1 and 1 each having a side of about 200 mm or less. However, for tiles that exceed this size (for example, large tiles with a side of 300 mm or more), tile 1
However, due to the weight, slippage occurs in the mounted state, and before the adhesive hardens, the acute-angled side portions 1a, 1a in the butt state may not be perfectly aligned with each other. For this reason, the obtained accessory tile was unusable, such as one of the acute-angled side portions 1a protruding on the outer corner surface side, and could not be distributed to the market as a product.

The present invention has been made in view of the above circumstances, and not only tiles whose one side is less than 300 mm,
To provide a new joining jig (hereinafter referred to as the present jig) that can join the tiles well to form a accessory tile even for large tiles exceeding 00 mm. To aim.

"Construction of device" (Means for solving the problem) The gist of the present jig is that the end faces of the plate-shaped tiles that are vertically erected are butt-bonded to each other in a state where they have crossing angles with each other and are held by adhesion. In the joining jig configured to form the accessory tile, a base for receiving each flat tile in an upright posture, and a back pressure body and a pressing body erected on the base are provided. , The back pressure body and the pressing body are arranged so as to face each other with a tile sandwiching space therebetween, and on the vertical side portions on both end sides of each flat plate tile with respect to the respective standing positions of the flat plate tile. Correspondingly positioned, the pressing body is provided with a clamp end capable of advancing and retracting toward the back pressure body so as to sandwich both ends of each tile with the back pressure body. .

(Operation) The tile is placed on the base in an upright posture. Therefore, the load of the tile is not concentrated on the joining target portion where the tiles are butted against each other, and never slips on the base. In addition, since each tile is fixed by being pressed against the back pressure body placed in the facing relationship by the pressing body, even if an external force other than sliding is applied to the tile, the adhesive cures. The position of the abutting portion as described above will not be displaced before the operation.

(Embodiment) The present invention will be described below with reference to the drawings showing an embodiment thereof.

FIG. 1 is a perspective view showing the jig of the present invention. The main jig is
A back pressure body 6 and a pressing body 7 are erected on a base 5.

The back pressure body 6 and the pressing body 7 are arranged so as to be opposed to each other to form a pair, and a sandwiching space capable of accommodating the wall thickness dimension of the tile between the two opposing surfaces. Are formed. Then, on the base 5, three pairs of the back pressure body 6 and the pressing body 7 forming the pair are arranged in total.

The back pressure body 6 has a height that is substantially comparable to the height dimension when the tile 1 (shown by the chain double-dashed line) is erected. Of the three back pressure bodies 6, 6, 6, the one arranged at the center has the support plates 8, 8 for the tile 1 attached to the upper and lower portions thereof. The support plate 8 has two tiles 1, 1
They are opened at an angle that allows them to bend each other, and leaning pieces 6a, 6a, ... Made of rubber or the like are attached to the front surface thereof. On the other hand, except for the back pressure body 6 at the center, the two back pressure bodies 6 and 6 on both sides have flat front faces and are formed in a vertically long rectangular shape. Further, leaning pieces 6a, 6a, ... Also made of rubber are attached to the upper and lower ends of the rectangular front face. Each of these three back pressure bodies 6 is attached to a seat surface portion 6b which is to be installed on the upper surface of the base 5, and a hanging piece.
6c is provided. The hanging piece 6c is designed to fit snugly into the slide groove 5a formed in the upper surface of the base 5, and restrains the directivity when the back pressure body 6 is erected. . In addition, a slide groove recessed on the base 5
5a is recessed so as to correspond to the bending angle when the tiles 1, 1 are butted against each other.

The pressing body 7 has a height corresponding to about half the height of the tile 1 when the tile 1 is erected. Therefore, it has only about half the height of the back pressure body 6. The pressing body 7 comprises a mount 7a made of an angle material having an L-shaped cross-section and the like, and a clamp end 12 movably provided on the top of the base 7a. FIG. 2 is a side sectional view showing the top of the pedestal 7a of the pressing body 7, and is drawn for easy understanding of the forward / backward movement of the clamp end 12. The clamp end 12 is formed on a projecting end surface of a truncated cone portion made of rubber or the like. The frusto-conical portion is connected to a shaft 10 via an advancing / retreating piece 9, and the shaft 10 is held by a guide bush 11 fitted in a clamp case 13 so that the sliding thereof in the front-back direction is maintained. It has become. The shaft 10 has a rear end connected to a clamp lever 15 via a link 14, and the clamp lever 15 is attached to the clamp case 13 so as to rotate about a fulcrum 15a. There is. Therefore, when the clamp lever 15 is rotated in the lifting direction as shown by the chain double-dashed line, the shaft is moved by the link 14.
The 10 is pushed forward and the clamping end 12 is adapted to press the tile 1 against the back pressure body (see FIG. 1). As shown in FIG. 1, the pressing body 7 thus constructed is
So as to face the back pressure bodies 6, 6, 6 standing on the base 5,
All three are erected. In addition, the pressing body 7 arranged in the center is provided with an advancing / retreating piece 9 having a triangular shape so as to correspond to an angle at which the two tiles 1 and 1 are bent,
The clamp ends 12, 1 are attached to the respective slopes of the advancing / retreating piece 9.
2 is installed.

By the way, as is apparent from FIG. 2, even when the clamp lever 15 is pushed down to retract the clamp end 12, the space between the clamp end 12 and the tile 1 is limited. Only a narrow gap is created. Therefore, it may be difficult to set or lower the tile 1 on the base 5. Therefore, in this embodiment, as shown in FIG. 3, the clamp case 13 is attached so as to be able to be inverted with respect to the mount 7a of the pressing body 7. That is, the clamp case 13 and the gantry 7a are connected by the hinge portion 16 (see also FIG. 1). By doing so, a wide space can be formed between the pressing body 7 and the back pressure body 6, and when the tile 1 is taken in and out, the tile 1 and the pressing body 7 are placed.
Alternatively, the back pressure body 6 is not damaged.

In the three pressing bodies 7,7,7, the fixing to the base 5 is
It is performed by an appropriate structure (not shown) such as bolt tightening. Similar to the case of the back pressure bodies 6, 6, 6, a slide groove for the pressing bodies 7, 7, 7 may be provided in the upper surface of the base 5 as well. In that case, it is possible to easily adjust any positioning aiming at the vertical side from a small tile having a side length of 200 mm or less to a large tile having a side length of 300 mm or more.

To join the tiles 1 and 1 using the jig of this invention, first,
One side where each tile 1 and 1 will be joined
The tiles 1 and 1a are finished in an acute angle, and both tiles 1 and 1 are placed flat on a flat plate such as a work table so that the acute angle side portions 1a and 1a face each other and face each other. Then, a paper tape or the like is attached so as to straddle the acute-angled side portions 1a, 1a in the butted state. Subsequently, both tiles 1 and 1 are turned upside down, and a resin adhesive is applied to the triangular groove portion formed between the acute angle side portions 1a and 1a. Next, both tiles 1 and 1 are placed in a standing posture on the base 5 of the jig of the present invention, and applied to the back pressure bodies 6, 6, 6. In this state, the tiles 1 and 1 are bent at a predetermined intersection angle. Then, in each pressing body 7,7,7, after setting the respective clamp cases 13,13,13 into the set state, the respective clamp levers 15,15,
Operate 15 to press the clamp end 12 against the tiles 1 and 1, and then wait for the adhesive to cure. At this time, if the jig of the present invention in the state where the tiles 1 and 1 are held is carried into a drying oven or the like and forcedly dried, dripping of the adhesive agent is prevented and a neat finish can be expected. As a drying condition, it was sufficient to leave it at about 80 ° C. for about 40 minutes.

(Study of Another Mode) In the above-described embodiment, the height of the pressing body 7 is set to about half of the height of the back pressure body 6. This is because the tile 1 is sandwiched in the thickness direction by three points. This is because it was judged that the support in the above was sufficient. However, the height of the pressing body 7 is set to the back pressure body 6
The tile 1 may be supported at four points or more on its front and back sides. Further, the forward / backward structure of the clamp end 12 of the pressing body 7 is not limited to that of the above-described embodiment, but may be replaced with a disk cam or a simple lever structure (both not shown). be able to. Furthermore, when the tiles 1 and 1 are joined together, the bending angle provided between the tiles 1 and 1 can be arbitrarily changed from an acute angle to an obtuse angle. The jig of the present invention can also be applied to the case where the jigs are joined in a shape. As described above, the configuration and shape of the jig of the present invention can be appropriately changed according to the embodiment.

"Effect of device" As is clear from the above description, the joining jig for forming accessory tiles according to the present invention can be used even when joining large tiles whose one side length exceeds 300 mm. , The tiles can now hold each other. Of course, even with this large-sized tile, the edges to be joined do not shift, and they match exactly. In other words, if the jig of the present invention is used, products that cannot be distributed to the market will not be produced, and therefore the yield rate will not decrease due to the bonding deviation. It has the excellent advantages of
