Description
Technical field
The utility model relates to technical field of bridge engineering, particularly a kind of arch bridge syndeton.
Background technology
In prior art, prefabricated arch bridge can adopt dry type to be connected with wet type with the connected mode of cast-in-situ steel reinforced concrete abutment, can be divided into being articulated and connected being connected with consolidation according to the power transmission difference connected; Employing wet type connects, and node construction difficulty is large, and common dry type connects, and as steel slugging etc., effectively can not transmit moment of flexure again.
Summary of the invention
The utility model provides a kind of new arch bridge syndeton, can ensure effectively to transmit horizontal force, vertical force and moment of flexure, effectively can realize the stress performance of consolidation.
The utility model is realized by following technological means:
A kind of arch bridge syndeton, comprise cast-in-situ steel reinforced concrete abutment, prefabricated arch bridge, described arch bridge comprises the body of a bridge of arch springing and arch, described arch springing entirety is in upside-down trapezoid, described arch springing is arranged a row or and arrange above prestressing apparatus, described prestressing apparatus is for connecting arch springing and steel concrete abutment.
Wherein, described prestressing apparatus comprises vertical direction through the bellows of arch springing, supporting ground tackle and prestressing force prestressing force indented bars, and bellows is embedded in cast-in-situ steel reinforced concrete abutment and Prefabricated arch bridge arch pin.
Wherein, described supporting ground tackle comprises anchor bolt and anchor plate.
Wherein, described ripple ipe grout, and adopt C35 microdilatancy pea gravel concreten sealing off and covering anchorage.
Wherein, between described bellows and prestressing apparatus, anticorrosive coat is set.
Finally, filling gel between described cast-in-situ steel reinforced concrete abutment and the connecting sewing of arch bridge.
The arch bridge syndeton more than realized, has the advantages that construction is simple, safe and reliable, durable in use, facilitate installing/dismounting, will bring huge benefit can to the economy of China and social development, have broad application prospects.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below with reference to accompanying drawing, specific implementation process of the present utility model is described in detail.
A kind of arch bridge syndeton, as shown in Figure 1, comprise cast-in-situ steel reinforced concrete abutment 1, prefabricated arch bridge 2, described arch bridge 2 comprises the body of a bridge of arch springing and arch, and described arch springing entirety, in upside-down trapezoid, described arch springing is arranged a row or and arranges above prestressing apparatus, described prestressing apparatus, for connecting arch springing and steel concrete abutment 1, preferably arranges the prestressing apparatus described in 2 rows in the present embodiment.
Specifically, as shown in Figure 1, described prestressing apparatus comprises vertical direction through the bellows 3 of arch springing, supporting ground tackle and prestressing force indented bars 4, and described bellows 3 is embedded in cast-in-situ steel reinforced concrete abutment 1 and prefabricated arch bridge 2 arch springing.Namely in one section of described bellows 3 being embedded in when cast-in-place described steel concrete abutment 1, make when then lifting described prefabricated arch bridge 2, in the arch springing preformed hole described in another section of insertion of described bellows 3, then prestressing force indented bars 4 to be inserted described bellows 3; Then supporting ground tackle anchor bolt 5 and anchor plate 6 are fastened to the two ends of described prestressing force indented bars 4, namely being fixedly connected with of described steel concrete abutment 1 and arch bridge 2 arch springing is completed, in order to make prestressing force indented bars 4 more fastening with the connection of described bellows 3, be in the milk in described bellows 3 by grouting preformed hole 32, then adopt C35 microdilatancy pea gravel concreten sealing off and covering anchorage.In order to increase application life and the environment resistant corrosive power of prestressing apparatus, between described bellows 3 and prestressing apparatus, anticorrosive coat is set.Finally, filling gel 7 between described cast-in-situ steel reinforced concrete abutment 1 and the connecting sewing of arch bridge 2.
In the assembled process of the prefabricated arch bridge 2 of lifting splicing, ensure that prestressing force indented bars 4 inserts arch springing pre-buried bellows 3 inside aperture and ensures installation accuracy, prestressing force hydraulic jack stretch-draw prestressing force indented bars 4 is adopted, by 0.85 times of yield strength Shi Hanzhang in prestressing force indented bars 4 stretching process after arch springing is accurately located.Should adopt during stretch-draw Stress Control, strain check method carry out.The deviation of actual measurement stretch value and calculated value should within ± 6% scope.Presstressed reinforcing steel should be avoided in prestressed stretch-draw to rupture or come off, and rupturing when generation or come off is that prestressing force indented bars 4 must be changed.
In order to make the fixing more firm of arch bridge 2 and abutment, the prestressing apparatus that can arrange described in many rows carries out the fixing of abutment 1 and arch bridge 2, and the quantity of often arranging described prestressing apparatus is arranged according to the reasonable wide of steel concrete abutment 1 and arch bridge 2.
When structure of the present utility model makes to overcome arch bridge construction in prior art, wet type is cast-in-place manufactures the low precision, the inefficient problem that exist, also overcomes the problem that the prefabricated arch bridge of dry type effectively can not transmit moment of flexure.
