As Fig. 2, particularly, first link 50 and the second link 52 are connected with beam end plate 54 respectively, reserved bolt 4 passes beam end plate 54 and is fastenedly connected, the beam end plate 54 of the first link 50 is resisted against first and closes up the beam end plate 54 of embedded board 3, second link 52 in face 10 and the right side tight abutment regulating cushion block 7.Above-mentioned framework beam 5 is stiff skeleton.
With reference to Fig. 3, it is the structural representation of wedge single in Fig. 2.With reference to Fig. 4, corresponding to the sectional structure schematic diagram in B-B face in Fig. 3.With reference to Fig. 5, for corresponding to the plan structure schematic diagram of Fig. 4.
Shown in composition graphs 2 to Fig. 5, cushion block 7 is regulated to comprise adjusting bolt 70 and at least two pieces of wedges 72, every block wedge 72 includes crossing minor face face 720, face, long limit 722 and inclined edge surfaces 724, inclined edge surfaces 724 offers regulating tank 726, this regulating tank 726 is to wedge 72 sunken inside and extend conducting and go out minor face face 720, simultaneously, the length that this regulating tank 726 extends is greater than the half of face 722, above-mentioned long limit length, mutually spliced by respective inclined edge surfaces 724 to make two pieces of wedges 72, and then ensure that the regulating tank 726 on two pieces of wedges 72 docks conducting, above-mentioned adjusting bolt 70 is through the regulating tank 726 of mutual conduction, turn adjusting bolt 70 forces two pieces of wedges 72 to relatively move along inclined edge surfaces 724, and then the respective face, long limit 722 of two pieces of wedges 72 closes up face 20 respectively to the second link 52 and second and moves, second link 52 is resisted against face, long limit 722 and is fastenedly connected with reserved bolt 4.
After having said structure feature, the utility model can by following implementation Process:
With reference to Fig. 6, first of the utility model stiff skeleton structure implements view.As shown in Figure 6, in the first toothholder 1 and the second toothholder 2, wear anchor bar, then concreting, the concrete pad of a profile of tooth is formed respectively with the both sides at bridge closure section.
With reference to Fig. 7, for correspond to Fig. 6 second implements view.As shown in Figure 7, close up anchoring installation embedded board 3 on face at relative two of the first toothholder 1 and the second toothholder 2, and along closing up direction, reserved bolt 4 is fixed on embedded board 3.
With reference to Fig. 8, for the correspond to Fig. 7 the 3rd implements view.As shown in Figure 8, adopt stiff skeleton to be placed in closure segment place as framework beam 5, the first link 50 of framework beam 5 is resisted against first closes up face 10 by reserved bolt 4 is affixed.The beam end plate 54 being positioned at the second link 52 is arranged in second close up on the reserved bolt 4 in face 20, but wouldn't be fastening.
With reference to Fig. 9, for the correspond to Fig. 8 the 4th implements view.With reference to Figure 10, for corresponding to the structure for amplifying schematic diagram in C region in Fig. 9.
Shown in composition graphs 9 and Figure 10, by the total length of the bridge closure section of construction setting, calculate the due distance of physical length control interval 6, adjustment cushion block 7 is adjusted to applicable width, neoprene bearing 8 tight abutment closes up face 20 in second, regulates cushion block 7 compound rubber bearing 8 and then forms the length adjustment interval 6 reaching designing requirement.By beam end plate 54 tight abutment at framework beam 5 second link 52 place in regulating the face, long limit 722 of cushion block 7, and in addition bolton.
Wherein, scrutinize Figure 10, at its second link 52 of framework beam 5 against in fastening real process, need particularly point out, because the toothholder being in closure segment both sides is not probably be in absolute same level, and then cause the beam end plate 54 at the second link 52 place not to close up face 20 keeping parallelism with second, and certain angle excursion a may be there is, therefore, after the second link 52 is squeezed in the face, long limit 722 on right side, neoprene bearing 8 pressurized and the distortion formed corresponding to angle excursion a, after neoprene bearing 8 deformation, cushion block 7 is regulated just to be close to the second link 52 completely, with this, the angle excursion of whole framework beam 5 is finely tuned be achieved, avoid construction error.
After completing above-mentioned implementation process, following characteristics of the present utility model should be reflected:
