JP2011017211A - Metal joint with temporary clamping claw - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a metal joint with a temporary clamping claw, which can be applied irrespective of the size of the metal joint and has good usability.SOLUTION: A column side fitting piece 1 to be fitted to a column p and a sill side fitting piece 2 to be fitted to the sill b orthogonal to the fitting piece 1 are respectively formed with a fitting hole 3 undergoing the insertion of a fixing rod 4 used for fitting the fitting pieces to the column p or the sill b. Then, a temporary clamping claw 5, which is a cut and raise piece formed by punching the column side fitting piece when forming the fitting hole 3, projects on the circumferential edges of the fitting hole 3 of the column side fitting piece 1.

Description

  The present invention relates to a joint fitting with a temporary pawl that is used, for example, between a pillar and a base for reinforcing a frame of a wooden building.

  For example, a mounting hole for a fastening rod with a locking rod (head) such as a screw nail to be mounted on the column or the base is provided on each of the piece to be mounted on the column and the other piece that is orthogonally mounted on the platform. The one piece is overlapped on one side of the column and the tip of the fastening rod is embedded in the column through the mounting hole, while the other piece is fixed to the base with the fastening rod in the same manner, and the joining state of the column and the base It is well known that there is no need to give a specific example of a metal fitting having a structure that reinforces the metal.

  In this known example, it is better to perform temporary fixing using a fixing rod with a fixing rod when temporarily fixing the column or the base with a fixing rod, and using a fixing rod with a locking rod. In addition, it is known that a stable joining state can be obtained by eliminating erroneous work.

  And as said temporary fix | stop means, the thing of the structure which projected the latching claw so that it might cut and raised on the back surface side of a joining metal fitting (for example, patent documents 1), or the latching claw so that it might cut and raised on the surface side There is a configuration (for example, Patent Document 2) that is formed and temporarily locked (fixed) by embedding the locking claw in a wood such as a column.

  In the past, the former has a locking claw at the end of the joining bracket (component piece thereof), so in the case of a large-sized joining bracket, the locking claw may not temporarily act. Since the former has locking claws on each piece arranged in the orthogonal direction, the locking claws between the pieces must be moved forward in the orthogonal direction to perform temporary fixing work. Is complicated.

  Moreover, in the latter case, even if the former drawback can be solved, the locking claw is opened (fired) other than the mounting hole for fixing and inserting the locking claw on the plate surface of the joining bracket. Therefore, it will affect the strength of the joint fitting, and it will require a part for mounting holes and a part for locking claws. ) Must be ensured, and there is a problem that it cannot be applied to a small joint fitting.

  The present invention has been devised for the purpose of providing a joint fitting with a temporary pawl that can be applied regardless of the size of the joint fitting and is easy to use, paying attention to the drawbacks of such conventional examples.

  In a joint fitting that attaches to the surface of wood such as a base with a fastening rod and joins the pieces of wood together, the attachment hole that penetrates the fastening rod has been cut and raised when forming the attachment hole. It is set as the structure which protruded the temporary stop nail | claw which consists of a cut-and-raised piece.

  According to the present invention, since the engaging claw is provided on the periphery of the mounting hole that the joining metal fitting always has, the joining metal fitting with a temporary retaining claw can be provided regardless of the size of the joining metal fitting.

  The drawings show an embodiment of the joint fitting with temporary pawl according to the present invention. In the drawing, A is a joint fitting with temporary pawl, and the joint A is formed by bending a metal plate by pressing. The column-side mounting piece 1 that is fixed to one side of the column p and the horizontal member-side mounting piece 2 that is fixed to one side of the horizontal member b such as a base or a horizontal member are arranged in an orthogonal direction and connected to each other. In the column side mounting piece 1 and the cross member side mounting piece 2, mounting holes 3 and 3 ′ are provided, and the screw nails 4 are passed through them to connect the mounting pieces 1 and 2 to the column p or the side. It is made to adhere to the material b (beam or foundation).

  And the temporary claw 5 protrudes in the peripheral part of a pair of attachment holes 3 and 3 of the column side attachment piece 1 with the column side attachment piece 1 in the rear direction, and this temporary fixation claw 5 is made of wood. In the example, the joining metal A is temporarily fixed to the column p by being embedded (dried) in the column p, so that the efficiency of the main fixing operation by the screw nail 4 through the mounting hole can be improved.

  The temporary pawl 5 is formed of a cut-and-raised piece formed by bending a triangular tongue-like piece formed by punching a predetermined part of the column-side mounting piece 1 in a semicircular shape from the front surface to the back surface, and punching operation and bending are performed. A circular hole formed by operation (of the tongue-shaped piece) is used as the mounting hole 3.

  The temporary pawl 5 provided at the peripheral edge of the attachment hole 3 is provided at the lowest position on the peripheral edge of the attachment hole 3, but is not necessarily provided at the lowest position, but provided at the lowest position. Thus, it can be applied as a guide material for embedding the screw nail 4 (which may be a fastening rod locked to each of the pieces 1 and 2) through the mounting hole 3 in the column p. When a so-called nail is driven instead of a screw nail, the driving guide and angle correction can be performed.

  Further, in the examples, the present invention is also applied to the joint between the pillar and the foundation, but the point is that it is only necessary to join woods which are wooden frames of a wooden building, and an arrangement relationship in which the woods are orthogonal to each other. Not necessary.
