Abstract

The method for producing an assembly is a method for producing an assembly equipped with a member to be reinforced (20), a reinforcing member body (41), and a filler (42), wherein the reinforcing member body (41) has a pair of flanges (44) arranged spaced on the surface (20B) of the member to be reinforced (20), a web (45), and a connection portion (46) which connects the flanges (44) and the web (45) and forms a filler space (V) with the surface (20B). The method for producing an assembly includes a step for inserting a filler (42) into the filler space (V), a step for attaching a crack control member (43) to cover the end of the filler (42), a step for joining the flanges (44) and the member to be reinforced (20), and a step for curing at least the member to be reinforced (20).

First claim

The invention claimed is:

1. A reinforcing member comprising:
a reinforcing member body that is attached to a surface of a member to be reinforced extending at least in one direction and extends in the one direction; and
a filler that is provided between the reinforcing member body and the surface and extends in the one direction,
wherein in a cross sectional view orthogonal to the one direction, the reinforcing member body has
a pair of flange portions that extends along the surface and is arranged at an interval on the surface,
a web portion that extends in a direction intersecting the surface, and
a connecting portion that connects the pair of flange portions and the web portion to each other and forms a filler space allowing the filler to be inserted therein between the surface and the connecting portion,

wherein the reinforcing member further comprises a crack regulating member that covers at least a filler end face in the one direction such that the crack regulating member extends to straddle an end face of the reinforcing member body in the one direction, and
wherein the crack regulating member has a panel shape having a panel face which faces the filler end face.

2. An assembly comprising:
the member to be reinforced; and
the reinforcing member according to claim 1 that is attached to the surface of the member to be reinforced.

3. The reinforcing member according to claim 1 ,
wherein the filler has a filler bottom face facing the surface of the member to be reinforced, and
wherein a crack extending in a direction intersecting the filler bottom surface is formed in advance in a portion including at least the filler end face.

4. The reinforcing member according to claim 1 ,
wherein the filler has a filler bottom face facing the surface of the member to be reinforced, and
wherein the reinforcing member comprises a crack causing portion that generates a crack extending in a direction intersecting the filler bottom face in a portion including at least the filler end face.

5. The reinforcing member according to claim 4 ,
wherein the crack causing portion is a film that extends along the crack.

6. The reinforcing member according to claim 1 ,
wherein the reinforcing member comprises a development prevention portion that is provided at a position separated from the filler end face and prevents development of a crack in the filler.

7. The reinforcing member according to claim 6 ,
wherein the development prevention portion is formed of a resin material, and
wherein the filler is formed of a material different from the resin material.

8. The reinforcing member according to claim 6 ,
wherein the development prevention portion is formed of a metallic material, and
wherein the filler is formed of a material different from the metallic material.
