Abstract

An adhesive injection method is for injecting an adhesive that bonds an outer plate and a reinforcing member. The reinforcing member has through holes bored through the reinforcing member in a direction intersecting a bonding surface facing the outer plate. The method includes positioning the outer plate and the reinforcing member; disposing a sealing material covering a gap between the outer plate and the reinforcing member; and injecting the adhesive into the through holes in order from one end to the other end of the bonding surface. At the injecting, while the adhesive is injected into the through hole, when the adhesive is recognized through another through hole formed adjacent to the through hole into which the adhesive is being injected, a through hole into which the adhesive is to be injected is shifted from the through hole into which the adhesive is being injected to the other through hole.

First claim

The invention claimed is:

1. An adhesive injection method for injecting an adhesive for bonding an outer plate and a reinforcing member, the reinforcing member having a plurality of through holes bored through the reinforcing member in a direction intersecting a bonding surface facing the outer plate, the adhesive injection method comprising:
positioning the outer plate and the reinforcing member;
arranging a seal to cover a gap between the outer plate and the reinforcing member; and
injecting the adhesive into the through holes in order from a first end to a second end of the bonding surface; and
removing the seal after solidification of the adhesive,
wherein during the injecting, while the adhesive is injected into a first one of the through holes, when the adhesive appears through a second one of the through holes adjacent to the first one of the through holes into which the adhesive is being injected, a location at which the adhesive is to be injected is shifted from the first one of the through holes into which the adhesive is being injected to the second one of the through holes, and
wherein the seal is a separate and discrete element with respect to the adhesive, and is configured to shape any adhesive protruding from the gap between the outer plate and the reinforcing member.

2. The adhesive injection method according to claim 1 , wherein the seal is configured to form the adhesive injected during the injecting into a tapered shape tapering from the reinforcing member to the outer plate.

3. The adhesive injection method according to claim 2 , wherein the seal is flexible to change a shape to swell toward an outside of the gap as the adhesive is injected during the injecting.

4. The adhesive injection method according to claim 2 , wherein the seal is a dam member which is a rigid body, and an inside of the dam member being formed in a tapered shape tapering from the reinforcing member to the outer plate.

5. The adhesive injection method according to claim 1 , wherein:
the seal includes a plurality of divided seal members, and
the seal members are arranged in order from the first end to the second end of the bonding surface, and
before the adhesive injected during the injecting protrudes beyond a range of a first one of the seal members arranged in place, a second one of the seal members is additionally arranged.

6. The adhesive injection method according to claim 1 , wherein, during the injecting,
suction is performed through the second one of the through holes formed adjacent to the first one of the through holes, and
when the adhesive appears through the second one of the through holes formed adjacent to the first one of the through holes into which the adhesive is being injected, a suction location through which suction is to be performed is shifted from the second one of the through holes through which the suction is being performed to a third one of the through holes formed adjacent to the second one of the through holes through which the suction is being performed.

7. The adhesive injection method according to claim 1 , wherein, during the injecting, a lid member is attached to the first one of the through holes into which injection of the adhesive has been completed.

8. The adhesive injection method according to claim 7 , wherein
the lid member comprises:
a lid body covering the first one of the through holes;
a protrusion extending in a protruding manner in a direction from the lid body toward the outer plate; and
a stopper located at a position of a predetermined length from a front end of the protrusion toward the lid body and configured to prevent the lid member from coming off from the first one of the through holes, and

wherein the lid member is configured to keep the thickness of the adhesive at a length defined based on the predetermined length.

9. The adhesive injection method according to claim 1 , wherein:
the bonding surface extends in a certain direction,
the through holes are formed in a pair of columns extending in the certain direction in a staggered manner, and
the seal extends in the certain direction and covers the gap formed on both sides of the joint between the outer plate and the reinforcing member.

10. The adhesive injection method according to claim 9 , wherein
the reinforcing member comprises:
a flange extending in a direction along the bonding surface; and
a web extending in a direction intersecting the bonding surface and in the certain direction, and

the through holes are formed in a pair of two columns in a staggered manner with the web sandwiched therebetween.

11. An adhesive injection method for injecting an adhesive for bonding an outer plate and a reinforcing member, the reinforcing member having a plurality of through holes bored through the reinforcing member in a direction intersecting a bonding surface facing the outer plate, the adhesive injection method comprising:
positioning the outer plate and the reinforcing member;
arranging a seal to cover a gap between the outer plate and the reinforcing member; and
injecting the adhesive into the through holes in order from a first end to a second end of the bonding surface,
wherein during the injecting, while the adhesive is injected into a first one of the through holes, when the adhesive appears through a second one of the through holes adjacent to the first one of the through holes into which the adhesive is being injected, a location at which the adhesive is to be injected is shifted from the first one of the through holes into which the adhesive is being injected to the second one of the through holes,

wherein, during the injecting, a lid member is attached to the first one of the through holes into which injection of the adhesive has been completed, the lid member including:
a lid body covering the first one of the through holes;
a protrusion extending in a protruding manner in a direction from the lid body toward the outer plate; and
a stopper located at a position of a predetermined length from a front end of the protrusion toward the lid body and and configured to prevent the lid member from coming off from the first one of the through holes, and
wherein the lid member is configured to keep the thickness of the adhesive at a length defined based on the predetermined length.

12. An adhesive injection method for injecting an adhesive for bonding an outer plate and a reinforcing member, the reinforcing member having a plurality of through holes bored through the reinforcing member in a direction intersecting a bonding surface facing the outer plate, the adhesive injection method comprising:
positioning the outer plate and the reinforcing member;
arranging a seal to cover a gap between the outer plate and the reinforcing member; and
injecting the adhesive into the through holes in order from a first end to a second end of the bonding surface,
wherein during the injecting, while the adhesive is injected into a first one of the through holes, when the adhesive appears through a second one of the through holes adjacent to the first one of the through holes into which the adhesive is being injected, a location at which the adhesive is to be injected is shifted from the first one of the through holes into which the adhesive is being injected to the second one of the through holes,
wherein the seal is a separate and discrete element with respect to the adhesive, and is configured to shape any adhesive protruding from the gap between the outer plate and the reinforcing member,
wherein the seal is configured to form the adhesive injected during the injecting into a tapered shape tapering from the reinforcing member to the outer
