The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after reading the utility model, those skilled in the art all falls within the application's claim limited range to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, the utility model discloses a kind of structural representation of double-deck spandrel-braced arch bridge.In this is implemented, double-deck spandrel-braced arch bridge comprises two basic courses departments 8, this basic courses department 8 arranges along roadbed 4, be separately fixed in two basic courses departments 8 with the first arch load receiving part 1 of corrugated steel making and the two ends of the second arch load receiving part 2, varying in size of the first arch load receiving part 1 and the second arch load receiving part 2 adopts brace summer to support betwixt.Brace summer comprises a plurality of the first brace summers 3 and the second brace summer 6.
Forward Fig. 2, Fig. 3 a and Fig. 3 b to, describe the connected mode of the structure of the first brace summer 3, the second brace summer 6 and they and the first arch load receiving part 1.As shown in Fig. 3 a and Fig. 3 b, the first brace summer 2 is zigzag, two kinks are divided into three parts, two ends be respectively the first connecting portion 31 and the second connecting portion 33, two kinks of same the second brace summer are divided into three parts, and two ends are respectively the 3rd connecting portion 61 and the 4th connecting portion 63.In other embodiments, the technician can arrange the bending angle of the kink of first, second brace summer according to actual needs.The connected mode of above-mentioned brace summer and the first arch load receiving part 1 is described with reference to figure 2.All have locating hole in the first connecting portion 31, the 3rd connecting portion 61 and the first arch support section 1, the three is stacked successively and use high-strength bolt 5 fix according to acceptable laying order on engineering.The first brace summer is the bridging structure that is inclined between the second brace summer in this embodiment, has further improved the weight capacity of bridge.
Forward Fig. 4 to, describe the connecting method of the first arch load receiving part of the present utility model or the second arch load receiving part.In this embodiment, the first arch load receiving part 1 or the second arch load receiving part 2 are spliced by the polylith corrugated steel, adjacent corrugated steel has certain overlapping and adopt high-strength bolt 5 fixing, is filled with weatherable materials 9 in overlapping connection gap, for example the weather-proof composite material of polypropylene.
