Coupling member, method for producing coupling member, and wooden member joint structure
First Claim
1. A coupling member, comprising:
- a metal rod-shaped main body portion to be embedded and held in a 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 portion protruding from the end face of the main body portion to a predetermined depth in a hole axially extending in the main body portion from a first open end to an opposing second end that is a deepest part of the hole, has a periphery separated from the main body portion so as to form an annular gap between the inner rod portion and the main body portion to allow axial deformation of the inner rod portion relative to the main body portion, and is integrally connected to the main body portion at the deepest part of the hole extending in the main body portion.

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.

7. A wooden member joint structure, comprising:
-
a coupling member, comprising; a metal rod-shaped main body portion to be embedded and held in a 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, the wooden member in which the coupling member is fixedly embedded; and the mating member joined to the wooden member by the coupling member, wherein the inner rod portion axially extends from a portion thereof protruding from the end face of the main body portion to a predetermined depth in a hole extending in the main body portion from a first open end to an opposing second end that is the deepest part of the hole, has a periphery separated from the main body portion so as to form an annular gap between the inner rod portion and the main body portion to allow axial deformation of the inner rod portion relative to the main body portion, and is integrally connected to the main body portion at the deepest part of the hole extending in the main body portion. - View Dependent Claims (8, 9)
