  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  The construction wood joining tool according to the present invention is constructed such that the building cross member 2 is formed on the folded free end side of the joining tool main body A in which the plate material 4 is folded into a folded shape having a U-shaped section or a U-shaped section. A joint connecting portion 4A that can be joined and connected to the joint portion 3 is provided, and a contact portion 4B that can be contacted and joined to the building vertical member 1 is provided at the folded portion on the opposite side of the joint connecting portion 4A. However, the plate member 4 is further bent to form a protrusion 4C having a shape protruding outward from the contact portion 4B.

  Therefore, for example, the connecting bolt 6 is passed through the bolt insertion hole 5 provided in a penetrating manner between the opposing side surfaces of the wooden building material 1, and the tip of the connecting bolt 6 is attached to one side surface of the building material 1. The projecting end of the connecting bolt 6 is passed through the bolt hole 7 of the present joint (joint body A), and a nut 8 is screwed onto the projecting end, for example, to return the contact 4B. Is fixed to the side surface of the building vertical member 1 in a state where it is brought into contact with the one side surface.

  Therefore, even in a fixed state in which only one connecting bolt 6 is used, the projecting portion 4C bites into and stops on the side surface of the vertical member 1 for construction, so that the present connecting device is built around the connecting bolt 6. It does not rotate with respect to the vertical member 1 for use, and a firm detent action is obtained.

  Therefore, even in a fixing situation in which only one connecting bolt 6 is used, this joining tool can be used only for fixing according to an ordinary construction method without requiring any other processing work such as nail fastening or screw fastening. It can be fixed to the material 1 in a non-rotating state.

  Further, in the present invention, since the plate member 4 is bent to form the protruding portion 4C that protrudes outward from the contact portion 4B, this configuration is a configuration that can be easily designed and realized. It can be configured at low cost.

  Further, for example, the unfolded plate material 4 before being folded and formed in the joint body A is folded into a folded shape having a U-shaped section or a U-shaped section so as to form the joint body A. Thus, if the projecting portion 4C having a shape protruding outward from the contact portion 4B is formed, the unfolded plate member 4 is simply folded and formed into the joint body A. Since the protrusion 4C can be formed simply by doing this, it can be easily realized without increasing the labor of bending compared to the conventional product.

  Further, for example, the unfolded plate material 4 before being folded and formed in the joint device main body A is formed into a shape having the projections 4C, and the plate material 4 having the projections 4C is joined to the joint device. By forming the main body A into a folded shape with a U-shaped cross-section or a U-shaped cross-section, the protrusion 4C is formed in a shape protruding toward the outer side of the contact portion 4B, for example, A portion corresponding to the contact portion 4B from the side corresponding to the joint connecting portion 4A of the plate member 4 by notching the unfolded plate member 4 before being folded and formed in the joint body A. By forming the plate member 4 having the protruding portion 4C protruding in the shape of a U-shaped section or a U-shaped cross section so that the plate member 4 having the protruding portion 4C is formed in the joint body A. , This projection 4C is the plate surface direction of the joint connecting portion 4A. If it is made into the structure which protrudes toward the outer side direction from the said contact part 4B, the expansion | deployment-shaped board | plate material 4 in which the projection part 4C is formed in advance will be folded and joined. Since the protrusion 4C is automatically formed only by constituting the tool body A, the present invention can be realized very easily, and a structure in which the protrusion 4C is formed by cutting out the plate material 4 is adopted. In this case, the plate material 4 having the protrusions 4C can be designed more easily by a simple method, and thus becomes more practical.

  Further, for example, if the plate member 4 is bent so that the plurality of protrusions 4C protrude outward from the contact part 4B, the plurality of protrusions 4C are side surfaces of the building vertical member 1. By biting into and locking, a stronger positioning (rotation prevention) action can be obtained.

  Further, for example, if the plate member 4 is bent and at least the protrusion 4C is configured to protrude from the vertical position with respect to the contact part 4B, the vertical position of the contact part 4B, that is, the connecting bolt 6 Since the protrusion 4C bites into and locks the side surface of the building vertical member 1 at the upper and lower positions of the position where the through hole penetrates, a very effective anti-rotation action is obtained.
