JPS5836211B2 - Wood bending connection method - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connecting method for forming boxes, cupboards, etc. by bending and binding wood such as wooden boards and sticks at their end faces.

Conventionally, this type of connection method includes, for example, a method of binding with nails,
Although there are methods using adhesives, each method has the drawback that sufficient strength cannot be obtained.

The object of the present invention is to provide a simple connection method that eliminates this drawback.The purpose of the present invention is to provide a simple connection method that eliminates this drawback. One or more cut grooves are formed at corresponding positions, and a metal connecting plate having a similar shape and wider width is inserted into each corresponding cut groove, and a metal connection plate is inserted from each cut groove to both sides. It consists of folding and tying the exposed side edges to the sides of the wood.

One embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Reference numerals 1 and 2 denote wood pieces to be joined to each other, and their end faces 3 are formed to be inclined in the longitudinal direction so that when they are butted together, they form a right angle or a desired angle.

One or more cut grooves 4 opening in the end faces 3 of both the pieces of wood 1 and 2 are provided, and these cut grooves 4 are located at corresponding positions in the pieces of wood 1 and 2, respectively.

Reference numeral 5 denotes a metal connection plate, and the connection plate 5 is an L-shaped plate wider than the cut groove 4 with bent sides, as shown in the second figure, and is inserted into the cut groove 4 from both ends. At that time, the side edges 6, 6 exposed on both sides from the wood 1, 2 are attached to the wood 1.
, are pressure bonded to the two sides.

The metal connecting plate 5 may be bent in advance on one side edge and bent on the other side after being inserted into the cut groove 4, or it may be inserted as a flat plate and the side edge bent. Furthermore, each side edge 6 may be divided and bent left and right as shown in the fourth figure.

FIG. 5 shows another embodiment, in which two connecting plates 5 shown in the second diagram are stacked one on top of the other and inserted into the corresponding cut grooves 4, 4, making it even stronger. connected to.

In this way, according to the present invention, wider metal connecting plates are inserted into corresponding grooves in the mating portions of the timbers that are aligned at right angles to each other or at an arbitrary angle on the end faces formed on the slopes. After fitting, the side edges exposed on both sides are bent along the wood, thereby binding the two pieces of wood, so the connection can be easily performed and has the effect of making the binding extremely strong.
