DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for bonding a plate. More specifically, the present invention relates to a method of bonding a plate body that is projected at a predetermined angle to bond an end surface of a plate body to an end surface of another plate body.

[0002]

2. Description of the Related Art Conventionally, in order to stick an end face of a plate body to an end face of another plate body by projecting it at a predetermined angle, the end face of the plate body is cut at an angle of approximately 1/2 of a predetermined angle. An adhesive is applied to the cut end surface, the acute angle and the acute angle of the end surface are brought into contact with the obtuse angle and the obtuse angle, respectively, and both ends are projected at a predetermined angle and held in a joined state to solidify the adhesive. It was glued.

As described above, a bonding method of a plate body in which an end face of a plate body and an end face of another plate body are bonded with an adhesive by protruding at a predetermined angle is, for example, an inner corner or an outer corner projecting at a predetermined angle. Is used for manufacturing an outer wall material used for the above, ie, a corner member of the outer wall.

[0004]

However, as in the prior art, the end face of the plate body and the end face of the other plate body are formed at a predetermined angle of about 1 °.
/ 2 angle, adhesive is applied to this end face, this end face is projected at a predetermined angle and held in a state of contact, and when the plate body and another plate body are bonded, an adhesive portion is formed. Will be easily peeled off.

[0005] In particular, when the corner member of the outer wall is manufactured by this method, there is a problem in that rainwater seeps into the bonding portion and freezes, causing so-called frost damage in which the bonding portion peels off.

Accordingly, an object of the present invention is to solve the above-mentioned problem and to provide a bonding method in which a bonding surface is firmly bonded and freezing damage or the like does not occur.

[0007]

Means for Solving the Problems The present invention has been made to solve the above problems and achieve the above object, and it is intended to protrude at a predetermined angle so that an end face of a plate and another plate are formed. A bonding method of a plate body for bonding an end surface, wherein an end surface of the plate body and an end surface of another plate body are cut so as to be approximately 1/2 of a predetermined angle, and an adhesive is applied to the cut end surface. Is applied so that the acute and acute angles of the end faces abut each other, and the obtuse and obtuse angles are in contact with each other. The joined plate bodies are stacked along and are held while a load is applied to both end surfaces opposite to the joined end surface to solidify the adhesive.

As the adhesive used in the present invention, all the commonly used adhesives can be used. However, an adhesive containing a thermosetting resin as a main component is preferable because of its high adhesive strength and good weather resistance. Examples of such an adhesive include an epoxy-based adhesive, an ester-based adhesive, and a urethane-based adhesive.

The tray used in the present invention may have any shape as long as the loading surface protrudes at a predetermined angle. For example, this loading surface may be a plate,
The plate may be provided with a large number of through holes.

However, if a tray having a loading surface formed by projecting two sets of roller rows in which a number of rollers are arranged in parallel at a predetermined angle is used, the end face of the plate and the end face of the other plate are not used. Is easily inserted into the loading surface of the tray by sliding it onto the loading surface of the tray.

In the present invention, the end face of the plate body and the end face of another plate body are projected and joined at a predetermined angle, and the joined plate bodies are stacked on the tray along the loading surface, and the joined end face is placed. A load is applied to both end surfaces on the opposite side, and this load may be applied in any manner.

For example, the weight may be held by hand and placed on the end face. Further, the weight may be automatically loaded by an electromagnetic method, hydraulic pressure, pneumatic pressure, or the like. A preferred example of a method for automatically placing a weight will be described. A through hole is provided in the weight, and a rod movably inserted into the through hole is attached to a position along the loading surface of the tray. It becomes movable along. On the other hand, a hydraulic or pneumatic locking claw is attached to the cylinder, a weight is hooked on the locking claw and lifted by hydraulic or pneumatic pressure, a plate is loaded on the tray, and the joining end face is There is a method of applying a load by lowering the weight on the opposite end faces. This method is convenient because it is not necessary to put the weight by hand.

In the present invention, the adhesive is applied to the end face of the plate body and the end face of another plate body, and the end faces are joined to solidify the adhesive. However, it is preferable to solidify by placing it in a curing room maintained at a high temperature because the bonding time is shortened.

Further, when the adhesive is solidified in the curing room, it is preferable that the adhesive be passed through the curing room, since the work proceeds continuously. To pass through the curing room, place the tray containing the plate on a trolley and pass the trolley through the curing room, or place the tray in a row of rollers in which conveyors and rollers are arranged in parallel in the curing room. Is provided in advance, and the tray on which the plate is placed may be placed on this conveyor or roller and passed therethrough.

[0015]

In the present invention, since the end surfaces of the plate and the other plate are cut at a half angle of a predetermined angle, both end surfaces are contacted by an acute angle and an acute angle, and by an obtuse angle and an obtuse angle. When this is joined, this plate and another plate are joined in a state of protruding at a predetermined angle.

In the present invention, the plates joined together in a state of projecting at a predetermined angle are stacked along a loading surface on a tray having a loading surface also projecting at a predetermined angle. It is kept at a predetermined angle.

In the present invention, after the tray is loaded on the tray having the loading surface protruding at a predetermined angle, the adhesive is solidified by holding a load on both end surfaces opposite to the joining end surface. It is firmly adhered and does not peel off due to freezing damage or the like.

Although the reason for this is unknown, the inventors guess that, when the adhesive is solidified and the plate and the plate are bonded, usually, when the adhesive is solidified, a very small amount is required. However, the adhesive shrinks, and fine holes are formed in the adhesive or between the adhesive and the plate. As a result, the adhesive strength is reduced, and water or the like enters the fine through-holes, and the adhesive surface may peel off due to freezing or the like of the water. However, according to the present invention, after being loaded on this tray, the adhesive is shrunk in a state where a load is applied to both end faces opposite to the joining end face, that is, both joining end faces are pressed against each other. However, it is considered that the plate is moved by the pressure in response to the shrinkage, and the adhesive is solidified and firmly adhered without forming fine through-holes.
