[0001]

[Industrial application] The present invention is a joint for joining building materials such as columns and beams (horizontal materials) used in wooden construction in the longitudinal direction, or a joint for joining by crossing. In the case of a woodworking machine for processing, a building material to be jointed and jointed at the end, that is, a material to be machined is cut into length dimensions and the end surface is jointed and jointed. The present invention relates to a joining jig for a work material that enables the processing even when it is difficult to process a joint or a joint to the end due to a short material.

[0002]

2. Description of the Related Art Conventionally, there are various kinds of joints and joint shapes for joining the ends of building materials. Particularly, the ends of the building materials used by cutting the length dimension are short. It is processed into large ant tenon, sickle tenon and other shapes. The above processing is performed by hand or machining by a woodworking machine, but in the case of this manual processing, the shape of the joint and the joint is limited, and especially in the shape including the curved surface in the protruding portion. The machining is extremely difficult, and in the case of machining, as shown in FIG. 5, the workpiece W ′ is accurately installed at the machining position with respect to the woodworking machine and the clamping means 10 is used.
It is difficult to fix (clamp) due to the above, and even if it can be fixed, the state becomes extremely unstable. Due to the fixing (clamping) failure, the processing accuracy is deteriorated and the safety during processing is reduced. The deterioration was unavoidable. Then, in order to facilitate the above-described machining, when a workpiece having a short length is installed and fixed (clamped) at a machining position of a woodworking machine, as shown in FIG. Using the member 10A and the auxiliary material 11A, the side jig member 10
A means for holding both sides of the workpiece W'by A, and as shown in FIG. 7, a lower jig member 10B and an auxiliary material 11B are used, and the workpiece W'is mounted on the lower jig member 10B. The means of placing was adopted.

[0003]

However, the means using the side jig member 10A described above requires a large opening width in the lateral direction of the clamp body in the side jig member 10A. The width of the work material W ′ that can be clamped is restricted with respect to the clamp width of the clamping device of the woodworking machine itself, and the lower jig member 10
In the means using B, it is necessary to change and correct the machining data corresponding to the thickness dimension of the lower jig member 10B. In both of them, the fixing means of the work material W'to the jig member is performed by nailing T or tightening bolts B. Therefore, it takes a lot of time to attach and detach the work material W'to the work material W '. This is not preferable because it leaves a trace of nailing or a hole for passing a bolt. Therefore, the present invention has been made in view of the above-mentioned conventional problems.
When processing joints and joints with a woodworking machine, a woodworking machine with a short length can be easily installed in the woodworking machine and the structure is simple and easy to handle. The purpose of the present invention is to provide a joining jig for the workpieces.
