Support member engages with haunched member, and 4 kinds of modes of motion roughly also can be used in combination these in the present invention.
The 1st mode
That is, the 1st mode is to use the method for U word shape spicule.
A kind of load-transfer device that has projection, be that resin system projection is that the back side is provided with on this convex support portion of thermosetting resin system load-transfer device of convex support portion by the integrated load-transfer device that forms of injection moulding, it is characterized in that:, use puncture to insert the U word spicule of load-transfer device convex support portion as the engagement means of resin system projection and this convex support portion.

Embodiment 3
Be to open along the load-transfer device length direction at the central portion of convex support portion 4 to wear
Through hole 15, simultaneously, insert the example of 1 spicule 14 at the other parts puncture.
For this embodiment, same as described above, the result of the restorative test of falling down, identical with embodiment 1,2 can confirm restorative.
For convex support portion 9, open along the Width of load-transfer device 1 and to wear
Through hole 16.
In this embodiment, make the width of the width of convex support portion 9 less than load-transfer device 1, haunched member 6 forms the width identical with the load-transfer device width.
About this embodiment, the result of recovery test of falling down same as described above, identical with embodiment 1,2 can confirm restorative.Perforation operation distance is long more then difficult more.
Central portion in convex support portion 4 is opened along the length direction of load-transfer device 1 and to be worn
Through hole, simultaneously, insert the hollow tube 17 (internal diameter 1.0mm, wall thickness 0.25mm, metallic) of external diameter 1.5mm, length 5.0mm to this through hole.
Carry out bonding strength test etc., table 1 ecbatic.
Anchoring strength is compared with comparative example 1, can confirm to improve more than 50%～2 times.Though flow chart is insertion 2 procedures of perforation operation and pipe, wear less hole and get final product owing to opening, and will manage patchhole, therefore, advantage is mistake to finish rarely.Restorative being identified.
Hollow tube is, if with comparative example 1 relatively, then the shaping thing by being packed into the thermoplasticity solid urethanes in the pipe and 2 fastening power of the state that pipe enters the projection body obtain the member of very high anchoring strength.
Insert this example of 1 spicule, anchoring strength a little less than.This thinks because spicule is not binding force with combining of projection body, but depends on the confining force that pin enters the state of projection body.Therefore, for the load of shearing stress, the projection body produces elastic deformation, separate owing to coming off, and be the lower object of anchoring strength so be speculated as.Because horizontal pressure acts on similarly, so separate come off dangerous higher from the state of horizontal commentaries on classics.
