As shown in Figure 1, in this example, the press surface 76a contacting with the tip end portion 22b of elastic component 22, form the face tilting with predetermined angular α with respect to the imaginary plane U that is orthogonal to the second wedge surface 74b, therefore can make to act on the component of elastic force of wedge member 20 towards the residing direction of the second bearing surface 64.Thereby when carrying out interim assembly working, the wedge member 20 that easily makes to ride on the second retainer 50 moves to the residing direction of the second bearing surface 64.
As shown in Figure 4, on the second fastening part 18, assemble under the state of elastic component 22 and wedge member 20 temporarily, can stop elastic component 22 mobile to the rightabout of pressing direction (Tu4Zhong right side) of elastic component 22 by enough the first retainers 48, can be enough the second retainer 50 stop wedge members 20 to elastic component 22 to press direction (left side in Fig. 4) mobile, so elastic component 22 and wedge member 20 are not easy to come off from the second fastening part 18.Again, the second fastening part 18 is applied in the situation of vibration or impact, also because elastic component 22 can absorb these vibrations or impact, elastic component 22 and wedge member 20 are not easy to come off from the second fastening part 18.Thereby, as mentioned above, can, before the second fastened member is moved into tunnel construction scene, elastic component 22 and wedge member 20 be assembled on the second fastening part 18 temporarily.
Fig. 6 is the stereogram that a part that the state of securing member 10 when promoting wedge members 20 and move it with the first abutting part 34 is shown forms section.Once interim assembly working completes, and the first fastened member 12 and the second fastened member 14 are moved into tunnel construction scene, with securing member 10, the first fastened member 12 and the second fastened member 14 is fastening.As shown in Figure 6, in fastening work, from the introducing port 62 of the second fastening part 18, the first abutting part 34 of the first fastening part 16 is imported to mobile route R, the first bearing surface 36 of the first abutting part 34 and the first wedge surface 74a of wedge member 20 are contacted.In this example, on the tip end portion 50b of the second retainer 50, form inclined plane 73, therefore can be simply by 73 importings along inclined plane of the first abutting part 34.
The first abutting part 34 is imported after mobile route R, as shown in Figure 1, the first abutting part 34 is further moved to the inboard of mobile route R, until anchorage element 24 is arranged as a linearity with anchorage element 38.In this example, the first wedge surface 74a of wedge member 20 at a slant, namely from more past base end part 20a mono-side of tip end portion 20b mono-side of wedge member 20 away from the first fastening surface 12a and the second fastening surface 14a, therefore the first abutting part 34 can be pushed away from length direction Y-direction the first wedge surface 74a.Thereby, can make wedge member 20 move together with the first abutting part 34, can enough wedge member 20 elasticity of compression members 22.In the situation of the gap S expansion after implementing between the first bearing surface 36 and the second bearing surface 64, by means of the elastic force of elastic component 22, wedge member 20 is inserted in the S of this gap.Can suppress like this fastening force that the expansion due to gap S causes declines.
