Specific embodiment
Referring to Fig. 1 to Fig. 9, simultaneously fixed lower prop 2 is first lifted, then by the interior table of the upper connection bucket 6 of the upper connector 4 of lower prop 2
Epoxy mortar or sulphide mastic are smeared in face, while smearing epoxy in the outer surface of the lower connection bucket 7 of the lower connector 3 of upper prop 1
Then clay or sulphide mastic lift upper prop 1, the lower connection bucket 7 of the lower connector 3 of upper prop 1 is inserted into the upper connection of lower prop 2
In the upper connection bucket 6 of part 4, then pass through bolt hole 5 with bolt and nut and be fixed temporarily lower connector 3 and upper connector 4, at this time lower prop
The taper hole B10 of 2 taper hole A8 and upper prop 1 are not necessarily completely coincident, then multiple tapers 9 are squeezed into the taper hole of lower prop 2
In the taper hole B10 of A8 and upper prop 1, the process of the taper hole A8 of lower prop 2 and the taper hole B10 of upper prop 1 are squeezed into first taper 9
In, if taper hole A8 and taper hole B10 misplaces, the head sections 16 of taper 9 first pass through taper hole A8 and taper hole B10 and pierce
In the concrete for entering the lower connection bucket 7 of lower connector 3, taper 9 exists with the identical section 18 of the identical section 17 and taper hole A of taper hole B
The relative position that lower connector 3 and upper connector 4 will be adjusted during penetrating taper hole A8 and taper hole B10 by force, forces
Taper hole A8 and taper hole B10 contraposition, then squeezes into taper 9 one by one, finally tightens the upper of the lower connector 3 of upper prop 1 and lower prop 2
The connection work of the hold-doun nut of connector 4, upper prop 1 and lower prop 2 is completed.Need to illustrate: hole 15 is straight hole, squeezes into wedge in taper 9
During pin hole A8 and taper hole B10, the shaft of taper 9 is always without impinging on the inner wall in hole 15, if the shaft of taper 9 is hit
To the inner wall in hole 15, device to hole 15 is caused to squeeze and is destroyed, the concrete on 15 periphery of hole can be involved, by the concrete pulling on 15 top of hole
It splits；The lower connection bucket 7 of lower connector 3 and the upper connection bucket 6 of upper connector 4 are designed to prismatic table shape, in the lower connector of upper prop 1
During 3 lower connection bucket 7 is inserted into the upper connection bucket 6 of the upper connector 4 of lower prop 2, it is easier to make each hole of lower connector 3
It is aligned with each hole of upper connector 4.
