Coupling Member, Method for Producing Coupling Member, and Wooden Member Joint Structure
First Claim
1. A coupling member, comprising:
- a metal rod-like main body portion to be embedded and held in an wooden member; and
an inner rod portion protruding from an end face of the main body portion and to be coupled to a mating member, the mating member to be joined to the wooden member or the inner rod portion to be coupled to a joint device secured to the mating member,wherein the inner rod portion axially extends from a protruding portion thereof to a predetermined depth in the main body portion, has a periphery separated from the main body portion to allow axial displacement of the inner rod portion relative to the main body portion, and is integrally connected to the main body portion at the deepest part thereof.

Abstract
Disclosed is a coupling member that enables a joint between a wooden member and a mating member to absorb vibration energy, and a method for producing the same and a joint structure using the same. The metal coupling member is embedded in the wooden member. The wooden member is connected with a mating member by the coupling member. The coupling member includes a metal rod-like main body portion to be embedded in the wooden member, and an inner rod portion protruding from the main body portion. The inner rod portion axially extends from a protruding portion thereof to a predetermined depth in the main body portion, has a periphery separated from the main body portion to allow axial displacement of the inner rod portion relative to the main body portion, and is integrally connected to the main body portion at the deepest part thereof.

10. A method for producing a coupling member, comprising the steps of:
-
forming a hole in a metal rod-like main body portion axially to a predetermined depth from an end face thereof; inserting a first end of a shaft member into the hole, the shaft member having a diameter that allows axial displacement of the shaft member in the hole relative to the main body portion; heating a tip at the first end of the shaft member inserted into the hole and a bottom portion of the hole; and connecting the shaft member and the main body portion by pressing and welding the tip of the shaft member and the bottom portion of the main body portion each other. - View Dependent Claims (11, 12, 13, 14, 15, 16)
