Detailed description of the invention
Embodiment is see shown in Fig. 1-2, a kind of vibration damping force transfer structure for bridge jointing, comprise the case beam 10 that both sides are to be spliced, the two bridges splicing fixtures 2 at positions and connector 1 and joint concrete 10, described connector 1 is that end sets up one group of girder steel on the wing plate 4 at two bridge splicing positions respectively, described girder steel is arranged along vertical bridge to interval, all be fixedly connected with by fixture 2 between the upper surface that soffit and two bridges of girder steel end splice the wing plate 4 at position, described fixture 2 is girder steel backing plate, girder steel end to be placed between two parties on girder steel backing plate and to be welded and fixed, the vertical bridge of girder steel backing plate has two row's connecting holes 6 on both sides of the edge, the wing plate 4 at simultaneously two bridges splicing positions has the high-strength bolt vertical core 8 corresponding with connecting hole, the screw rod 3 of high-strength bolt stretch into be full of adhesive 8 high-strength bolt vertical core 7 within, the nut 9 of high-strength bolt fixes and is welded on the upper surface of girder steel backing plate, between described case beam to be spliced and girder steel, joint concrete 5 is filled with in space between girder steel and girder steel.
Described girder steel is i iron or H profile steel.
The set up length of described girder steel end on the wing plate at two bridge splicing positions is all not less than 20cm.
The outward flange of the direction across bridge of described girder steel backing plate is concordant with the edge that two bridges splice the wing plate at position, and the inward flange of the direction across bridge of girder steel backing plate exceeds the end edge of girder steel.
In the present embodiment, described girder steel is No. 10 i iron preferably, and length is for stretching into each 20cm of the old and new's beam body scope.2 covers often organized by described girder steel backing plate 2, are 0.5m along vertical bridge to arrangement pitch; Described high-strength bolt indulges bridge to often organizing 16, and spacing is 5cm, and high-strength bolt performance rate is 8.8, and specification is M16, and length is 15cm, and top is screw thread structure.The diameter of corresponding high-strength bolt vertical core is 16mm.Described adhesive 8 is epoxide-resin glue.Girder steel backing plate is of a size of length × wide × height=25cm × 10cm × 1cm.
Girder steel is abound with in the old and new's case beam seam wing plate, both is forever linked into an integrated entity, jointly stressed.When carrying out spelling wide construction under old bridge uninterrupted traffic condition, traffic loading is effectively delivered to new bridge by steel frame beam, reduces seam two lateral deflection difference and inharmonious vibration, ensures joint concrete pouring quality and later strength.
Work progress of the present utility model is as follows:
Case beam wing plate upper surface is close to by girder steel backing plate, both eyelet accurate positionings overlap, there is the discrepancy in elevation and adjusted by the girder steel backing plate that thickness is different in the old and new's bridge floor, wash-up tray beam wing plate eyelet before installation high-strength bolt, infusion epoxy resin glue, squeeze into high-strength bolt, WELD NUTS and girder steel backing plate after 2 hours, bolt-weld joint ensures the connection reliability of girder steel backing plate and case beam wing plate.Girder steel backing plate is close to by girder steel, takes welding manner to be firmly connected at girder steel with the engagement edge of girder steel backing plate.
The main points that should be noted during construction have: must firmly weld during steel girder erection, high-strength bolt and girder steel backing plate, the firm bolt-weld joint of case beam wing plate, guarantee that the old and new's beam forms entirety, reliable power transmission; The complete resonance effect needing field test the old and new bridge of steel girder erection, the longitudinal pitch of steel frame beam is adjusted in time when power transmission effect is inadequate, change old bridge two lane into single lane away from seam side, restricted speed is 40Km/h, effectively reduce vehicle-mounted current time cause amount of deflection difference and effect of vibration at wet seaming position.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection domain of the present utility model.
