Description

[Detailed Description of Device] [Object of Device] (Industrial Application Field) The present invention relates to a structure of a joint portion of a vertical frame and a horizontal frame in a frame door.

(Prior Art) In most cases, the frame joints of the frame doors usually use both a dowel and a dowel with a short length of about 1/2 of the plate thickness (see Fig. 5). The groove has a constant width, and the degree of fitting is often tight.

Therefore, if a large amount of adhesive is put in the mortise hole, it will come out at the time of fitting, and if it is too small, it will not adhere sufficiently and will have to rely on the joint strength of the dowel. In case of dowel joining, usually 1
Since a plurality of dowels, about 3 to 4, are also used in the joining at the places, the number of dowel holes in the frame joining of the four surroundings is very large, and its positioning is difficult except for that.

In other words, if the diameter of the dowel hole is made slightly "loose" to facilitate the fitting of the dowel joint, it becomes easier to form a frame step, and if it is made "tight", there is the face that it becomes extremely difficult to fit. .

(Problems to be solved by the invention) Therefore, the present invention does not use the above-mentioned difficult tab joining,
A special joining projection and a groove are formed so that the joining can be performed firmly.

"Structure of device" (Means for solving the problem) The structure of the present invention has a length 1 to 2 times the plate thickness at the end of the horizontal frame at the joint between the vertical frame and the horizontal frame in the frame door. The joining protrusion is provided, and the shape thereof is formed in a taper shape that becomes narrower toward the tip, and the joining recessed groove which can fit into the joining protrusion and fits is formed in a vertical frame.

(Operation) In other words, providing the joining protrusion with a length 1 to 2 times the plate thickness at the end of the horizontal frame makes the length of the joining protrusion longer than that of the conventional hoso, increasing the bonding area and bonding. It will increase your power. However, if the joining protrusion is made too long, the yield will deteriorate and the corner strength of the vertical frame will be weaker on the contrary, so the length of the joining protrusion is preferably about 1 to 2 times the plate thickness.

By the way, when the shape of the joining protrusion is made long and the width is made constant, the adhesive often sticks out or becomes insufficiently bonded as described in the section of the prior art. Further, when an adhesive is put into the mortise holes, the adhesive is often distributed only on one side (displaced to the side where a gap is easily formed), and rarely evenly dispersed on both sides. When the adhesive is applied to the mortise, it is often rubbed at the entrance of the mortise hole at the time of fitting and the adhesive does not sufficiently enter the mortise hole.

Therefore, forming a taper-shaped joint projection that becomes thinner toward the tip and forming a joint groove that fits in this shape on the vertical frame can eliminate most of the conventional defects. confirmed.

That is, if an appropriate amount of adhesive is applied to both surfaces of the joint protrusion, the adhesive can be inserted and adhered to the bottom of the joint groove in a state where the adhesive is evenly distributed to the inside without being biased to one side. Therefore, the adhesive area can be used to the maximum,
The adhesive strength can be increased efficiently. It is easier to apply the adhesive to the mulberry than to put it in the mortise hole, and moreover, it can be applied uniformly.

(Example) 3.4 m / m thick rotary lace Yonematsu Veneer 11 sheets are laminated and bonded to the outermost layer of a veneer laminated material (called LVL). 120m / m × 1980m / m vertical frame and 36m / m × 1
50m / m × 550m / m upper horizontal frame (1), 36m / m × 210m / m × 550m / m
The lower horizontal frame (1 ') was created. The lower horizontal frame (1 '), which is a horizontal frame, was created. At both ends of the lower horizontal frame (1 ') and the upper horizontal frame (1), which are horizontal frames, the root is 10 m / m thick and the tip is 7 m thick.
50m / m long joint protrusion (2
a), and in the vertical frame part of the part that fits into this joint protrusion, the joint groove (2) with a shape that fits this joint protrusion (2a).
b) was made from top to bottom. Horizontal frame (1) (1 ')
The water-based vinyl urethane resin emulsion adhesive was applied by brush onto both surfaces of the joining projections at both ends prepared in 1. and fitted with the vertical frame (3) to assemble the door frame. A 10 m / m thick oak double-sided decorative plywood was attached to the central end plate part (4) together with both edges of oak to form a door.

When the frame joints of the doors created in the example were destroyed, the hoso and the groove were sufficiently adhered, and all 20 pieces of the test pieces were broken.
0% was obtained.

"Effects of the device" (Effects of the device) The protrusions and recesses of the present invention are easy to process and assemble, and it is easy to apply the adhesive. There is no effect, and the adhesive effect is large, which is an extremely beneficial effect.
