Abstract

PROBLEM TO BE SOLVED: To provide a light-weight connecting pin capable of being inserted with little resistance into prepared holes formed by machining in various structural members and being intentionally pulled out in the case of alteration or the like of a wooden building in spite of no possibility of slipping out unexpectedly. SOLUTION: The end part (12) of a metallic hollow pin body (10) is formed in such an approximately conical shape as to be tapered so as to be easily inserted into the pin receiving prepared hole (11) of the structural member (A). The head part (13) of the pin body (10) undergoes plastic deformation in such a manner as to have an approximately oval shape when viewed from the front, and a thread (15) with the ridge diameter (D2) larger than the bore (d) of the prepared hole (11) is recessed all over the outer periphery surface of the head part (13) or only on the facing circular arc surfaces on a major axis (Y). The pin body (10) is rotation-operated in the advancing direction of the thread (15) of the head part (13) by a rotation operating tool (23) for the connecting pin, which is locked for insertion to an approximately oval tool locking hole (14) opening in the head part (13) in such a manner as to be freely inserted into/extracted from the hole (14). The thread (15) is thereby set to bite the internal wall surface of the prepared hole (11).

[0003] The special connecting pin made of metal is disclosed in FIG. 4 of JP-A-9-287201 and JP-A-8-17036.
No. 9 and these are considered to be well-known technologies relatively similar to the present invention. However, since all of them are solid metal products, they are very often used in this kind of wooden building. As a result, the weight is unnecessarily increased, and there are the following problems.

The problem to be solved by the present invention is as follows:
Draft pin (6) suggested based on FIG. 4 of No. 7201
Are pin legs (6b) as elliptical shapes of the heads (6b).
By having a major axis dimension larger than the diameter of a),
When it is driven into the pin hole (7) of the base (1) or the pin hole (8) of the pillar (2), the head (6) is inserted into the pin hole (7) (8).
b) Even if the long axis portion is bitten and prevented from coming off, the outer periphery of the large diameter long axis portion projecting from the circumferential surface of the pin leg (6a) at the head (6b). The surface merely forms a simple arc of a fixed length parallel to the axis of the draft pin (6) itself.

[0005] For this reason, in combination with the fact that the draft pin (6) is used only by driving, when the size of the head (6b) projecting from the pin leg (6a) is small, the draft pin (6) is not used. The pin holes (7) and (8) can be driven into the pin holes (8) without difficulty, but if they are subjected to an external force such as vibration or impact during construction, they may easily come out.

On the other hand, if the overhanging dimension is large, a greater resistance is received, so that the driving operation becomes difficult.
The opening edge of (8) is damaged or cracks or distortions spreading from the opening edge occur, leading to weakening of the structural material itself such as the base (1) or the column (2).

[0010] This is a driving plug used for driving (1)
As a result, there is an effect that a structural material such as a column, a beam, or a girder does not crack or generate a large internal strain. For this purpose, the inner diameter of the plug driving hole is set to the outer diameter (φ) of the cylindrical portion (2) itself.
It is necessary to work with the same high precision as in 1), otherwise it is not possible to stably and securely bite into the hole for inserting the plug and fix it.
