Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
It is emphasized that "front", "rear" in the utility model, "left", "right" are corresponding with the "front", "rear" in " Fig. 2 ", "left", "right" respectively.
By shown in Fig. 1 to Fig. 5, a kind of PC rail beam linkage of the present utility model, comprise two connectors, each connector comprises end-blocking plate 2, buttcover plate 3 and front stiffening rib 4, two end-blocking plates 2 are separately positioned on the end face of adjacent two Pin PC rail beams 1, end-blocking plate 2 is provided with two row prestress wire through hole groups 20, described buttcover plate 3 one end is connected on corresponding end-blocking plate 2, the other end extends to another connector and is connected with it, and described front stiffening rib 4 is positioned at the relative inner of two end-blocking plates 2 and is connected with corresponding end-blocking plate 2 and buttcover plate 3 respectively.Described end-blocking plate 2, connecting as one between buttcover plate 3 and front stiffening rib 4.When prefabricated PC rail beam, for strengthening the reliability that end-blocking plate 2 is connected with PC rail beam 1, by whole steel strand anchorings of rail beam on end-blocking plate, need it also avoid at the elongated prestress wire of two times tensioning in operation of setting a roof beam in place simultaneously, ensured one-tenth bridge linear with design the linear goodness of fit.After adjacent two Pin PC rail beams 1 are linked together by described two connectors, at beam seam, place arranges cage of reinforcement, then concreting, makes PC rail beam become continuous beam by simply supported beam, and form consolidation with substructure, make entirely to be unified into as continuous rigid frame system structure.Use PC rail beam linkage of the present utility model, the gap formed between rail beam can be reduced, improve the comfortableness of train operation, reduce later stage operation expense.
As the further improvement of such scheme, each connector also comprises and being embedded in PC rail beam 1 end and the rear stiffening rib 5 be connected with corresponding end-blocking plate 2.Described rear stiffening rib 5 is connected effect for strengthening connector with PC rail beam 1 end is concrete.
As the further improvement of such scheme, the vertical median plane both sides of the buttcover plate 3 apportion PC rail beam 1 on two connectors and contact with each other and be bolted.Buttcover plate 3 arranges multiple through hole, by high-strength bolt through the buttcover plate 3 on two connectors, thus adjacent two Pin PC rail beams is linked together.Adopt above-mentioned setting, make the coupling stiffness between two connectors on adjacent two Pin PC rail beams larger.
As the further improvement of such scheme, described front stiffening rib 4 to comprise before first of apportion buttcover plate 3 both sides stiffening rib 41 before stiffening rib 40 and second, and before described second, stiffening rib 41 docks with the first stiffening rib 40 of another connector.Before buttcover plate 3 both sides arrange first, stiffening rib 41 before stiffening rib 40 and second, can strengthen the coupling stiffness between buttcover plate 3 and end-blocking plate 2.
As the further improvement of such scheme, before described first the long limit of stiffening rib 40 and buttcover plate 3 isometric.Before first, stiffening rib 40 can dock with stiffening rib 41 before second on another connector, thus strengthens the coupling stiffness between two connectors.
As the further improvement of such scheme, the edges at two ends place, left and right of described end-blocking plate 2 is respectively arranged with row for running through the hole group 21 of stirrup.Between beam seam, stirrup can form ring-shaped stirrup through after institute's hole group 21, and forms the reinforcing cage of node coagulation with vertical cage of reinforcement.
As the further improvement of such scheme, each connector also comprises the bearing 6 be arranged on below PC rail beam 1 end, described bearing 6 comprises the gripper shoe 60 being arranged on and being connected below PC rail beam 1 end and with rear stiffening rib 5 and the back-up block 61 be arranged on below gripper shoe 60, and described back-up block 61 is connected with the backing plate 7 be embedded on bent cap 8.After adjacent two Pin PC rail beams 1 have connected, bearing 6 is welded with the backing plate 7 be embedded in advance on bent cap 8, follow-up again at beam seam and adjacent two lower end, Pin PC rail beam 1 end concretings, make PC rail beam 1 and bent cap 8 become connecting overall.The cost of described bearing 6 about 0.7 ten thousand yuan, the cast steel supporter cost of original Simple Rail Bearer about 6.5 ten thousand yuan, and the concrete cost of building in lower end, PC rail beam end is very low, thus reduces cost.
As the further improvement of such scheme, described bearing 6 also comprises and arranging and the fixed head 62 be connected with back-up block 61 with end-blocking plate 2 isoplanar, fixed head about 62 two ends are respectively equipped with a bearing fixing hole 620, and described fixed head 2 and the Connection Block 9 be arranged on backing plate 7 are by being connected through the pin of described bearing fixing hole 620.The fixed head be positioned on two connectors of PC rail beam 1 left and right sides and two Connection Blocks be arranged on backing plate 7 are each passed through with two pins, make between bearing and backing plate fixing more reliable, thus play the effect of temporary fixed PC rail beam 1, no longer need to build falsework, decrease working procedure, reduce construction cost, improve efficiency of construction.
As the further improvement of such scheme, the cross section of described back-up block 61 in the perpendicular perpendicular to PC rail beam 1 end face is at right angles trapezoidal, and the width of back-up block 61 is less than the width of gripper shoe 60.The upper base of right-angled trapezium is welded with gripper shoe 60, and bottom is welded with the backing plate 7 be embedded on bent cap 8, adopts the design of right-angled trapezium, can reduce the weight of bearing 6.In addition, after PC rail beam links together, can concreting below PC rail beam 1 end, concrete also plays a part to support PC rail beam 1, thus the width design of back-up block 61 can be become be less than the width of gripper shoe 60, thus reduce the weight of bearing 6 further, and then reduce costs.
As the further improvement of such scheme, described fixed head 62 is connected with buttcover plate 3 bottom.Buttcover plate 3 bottom is extended, thus can weld together with fixed head 62, and then improve the rigidity of each connector.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
