Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for adhering plates. More specifically, the present invention relates to a method of adhering a plate body that is protruded at a predetermined angle to adhere 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 make an end face of a plate member adhere to an end face of another plate member by projecting it at a predetermined angle, the end face of the plate member is cut at an angle of about 1/2 of the predetermined angle, Apply the adhesive to the cut end face, contact the acute angle and the acute angle of the end face, the obtuse angle and the obtuse angle respectively, and hold both the end faces projected at a predetermined angle and joined to solidify the adhesive. It was glued.

As described above, a method of adhering a plate body in which an end surface of a plate body and an end surface of another plate body are adhered with an adhesive by projecting at a predetermined angle is, for example, an entering corner and a projecting corner projecting at a predetermined angle. It is used when manufacturing the outer wall material used for, that is, the corner member of the outer wall.

[0004]

However, as in the prior art, the end face of a plate body and the end face of another plate body are separated by a predetermined angle of about 1 mm.
Cut at an angle of / 2, apply an adhesive to this end face, hold this end face projected at a predetermined angle and abutting it, and bond the plate body to another plate body. The product becomes easy to peel off.

In particular, when the corner member of the outer wall is manufactured by this method, there is a problem that rainwater permeates the adhesive portion and freezes it to cause so-called frost damage in which the adhesive portion peels off.

Therefore, an object of the present invention is to solve the above problems and to provide a bonding method in which the bonding surfaces are 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-mentioned problems and achieve the above-mentioned object, and is made to project at a predetermined angle so that the end surface of a plate body and another plate body A method for adhering a plate body for adhering an end face, comprising cutting an end face of a plate body and an end face of another plate body at an angle of about 1/2 of a predetermined angle, and applying an adhesive to the cut end face. Is applied to the tray so that the acute angle and the acute angle of the end face and the obtuse angle and the obtuse angle of the end face are brought into contact with each other, and both end faces are joined by projecting at a predetermined angle, and the stacking face is placed on the tray having the stacking face projecting downward at the predetermined angle. The bonded plate bodies are loaded along with each other, and are held in a state where a load is applied to both end surfaces on the opposite side of the bonded end surfaces, whereby the adhesive is solidified.

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 it has high adhesive strength and good weather resistance. Examples of such adhesives include epoxy adhesives, ester adhesives, urethane adhesives, and the like.

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

However, when a tray having a stacking surface formed by protruding two sets of roller rows in which a large number of rollers are arranged in parallel to each other at a predetermined angle is used, the end face of a plate body and the end face of another plate body are It is preferable that those joined together at a predetermined angle can be easily inserted by sliding them sideways on the loading surface of this tray.

In the present invention, the end faces of the plate members and the end faces of the other plate members are projected and joined at a predetermined angle, and the joined plate members are stacked along the loading surface on the tray, and the joined end faces are joined together. A load is applied to both end surfaces on the opposite side of, but this load may be applied by any method.

For example, the weight may be held by hand and placed on the end face. Alternatively, the weight may be automatically placed by an electromagnetic method, hydraulic pressure, pneumatic pressure, or the like. A preferred example of a method for automatically mounting the weight will be described. When a through hole is provided in the weight and a rod movably inserted in the through hole is attached to a position along the loading surface of the tray, the weight is a plate body. It becomes free to move along. On the other hand, a locking claw that moves hydraulically or pneumatically is attached to the cylinder, and a weight is hooked on this locking claw to lift it with hydraulic pressure or pneumatic pressure. There is a method of lowering the weight on both ends on the opposite side to apply a load. This method is convenient because it does not require the weight to be placed by hand.

In the present invention, the adhesive is applied to the end face of the plate and the end face of another plate and the end faces are joined to solidify the adhesive. However, it is preferable to put it in a curing chamber kept at a high temperature to solidify it, because the bonding time becomes short.

Further, when the adhesive is solidified in the curing chamber, it is preferable that the adhesive passes through the curing chamber because the work is continuously performed. To pass through this curing chamber, place a tray containing a plate on a trolley and pass this trolley through the curing chamber, or use a row of rollers with conveyors and rollers arranged in parallel inside the curing chamber. It is advisable to preliminarily provide the passage of (1) and to place the tray on which the plate is placed on this conveyer or roller to pass through.

[0015]

In the present invention, since the end faces of the plate member and the other plate member are each cut at an angle of 1/2 of the predetermined angle, both end faces contact each other at an acute angle and an acute angle, and an obtuse angle and an obtuse angle. When joined to, the plate body and the other plate body are joined in a state of protruding at a predetermined angle.

Further, in the present invention, since the plate bodies joined in the state of projecting at the predetermined angle are stacked along the stacking surface on the tray having the stacking surface which also projects at the predetermined angle, this plate body is formed. It is held at a predetermined angle.

According to the present invention, after being loaded on the tray having the loading surface projecting at a predetermined angle in this way, the adhesive is solidified by holding the both end faces opposite to the joining end face under a load. It adheres firmly and does not peel off due to frost damage.

Although the reason for this is not clear, it is assumed by the inventor that, in general, when the adhesive is solidified and the plates are adhered to each other, a small amount of the adhesive may solidify. However, the adhesive contracts, and fine through 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 minute through holes, and the water may freeze, so that the adhesive surface may peel off. However, in the present invention, after being loaded on this tray, the adhesive contracts because both end faces on the opposite side of the joint end faces are joined under load, that is, both joint end faces are pressed together. However, it is considered that the plate member moves due to the contraction due to the pressure, and the adhesive is solidified and firmly adhered without the generation of fine through holes.
