Abstract
A double-arc-shaped bridge steel structure comprises a bottom plate, an upper top arc piece and a lower top arc piece. The two ends of the upper top arc piece and the two ends of the lower top arc piece are fixedly connected with the two ends of the bottom plate respectively, the radius of the upper top arc piece is larger than that of the lower top arc piece, connecting steel rings are arranged between the upper top arc piece and the lower top arc piece, and connecting ribs are arranged between the lower top arc piece and the bottom plate. Compared with the prior art, the double-arc-shaped bridge steel structure has the advantages of being reasonable in design, simple in structure, easy to mount, overall attractive and strong in bearing capacity.
Description
Technical field
The utility model relates to a kind of bridge steel structure, is specifically related to a kind of double-arc shape bridge steel structure.
Background technology
At present, traditional bridge has wooden bridge, stone bridge etc., generally be more common in Scenic Spots, common bridge generally adopts steel bar concrete casting to form, special bridge for some little spans, this bridge construction cycle is long, lack regular supervision, collapse accident also has generation more, this bridge is because the many uncertain factors that exist in the construction, directly cause its security reliability and effective service life to be difficult to obtain effective guarantee, also just can't guarantee the safety problems such as personal lives and properties of people in using bridge.The integral bridge aesthetic property of existing steel bar concrete casting is relatively poor simultaneously.
Summary of the invention
The purpose of this utility model is exactly the defective that exists for prior art, and a kind of double-arc shape bridge steel structure is provided.
Its technical scheme is: comprise base plate, upper top arc spare and lower top arc spare.Upper top arc spare is fixedly connected with the two ends of the equal base plate in two ends of lower top arc spare, and the radius of described upper top arc spare is greater than the radius of lower top arc spare, is provided with between upper top arc spare and the lower top arc spare to be connected steel loop, is provided with dowel between lower top arc spare and the base plate.
Wherein, described dowel is wire rope or reinforcement rod.
The utility model has the following advantages compared with prior art: reasonable in design, simple in structure, simple and easy, overall appearance is installed, weight capacity is strong.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, a kind of double-arc shape bridge steel structure comprises base plate 1, upper top arc spare 2 and lower top arc spare 4.The two ends of the equal base plate 1 in two ends of upper top arc spare 2 and lower top arc spare 4 are fixedly connected with, the radius of described upper top arc spare 2 is greater than the radius of lower top arc spare 4, be provided with several between upper top arc spare 2 and the lower top arc spare 4 and be connected steel loop 3, be provided with some dowels 5 between lower top arc spare 4 and the base plate 1.Wherein, described dowel 5 is wire rope or reinforcement rod.Connecting steel loop 3 is fixedly connected with for welded type with upper top arc spare 2 and lower top arc spare 4.Dowel 5 is fixedly connected with for welded type with base plate 1 and lower top arc spare 4.
The utility model arranges upper top arc spare 2 and lower top arc spare 4 by base plate 1 top, and be provided with dowel 5 at lower top arc spare 4 and 1 of base plate, effectively realized the function of bridge, the arc tension force of top arc spare 2 and lower top arc spare 4 in the utilization, by dowel 5 traction base plates 1, increase the weight capacity of base plate 1.Several that are provided with between upper top arc spare 2 and the lower top arc spare 4 are connected steel loop 3, have greatly strengthened the overall appearance of bridge.
Claims (2)
1. double-arc shape bridge steel structure, comprise base plate, upper top arc spare and lower top arc spare, it is characterized in that: the two ends of upper top arc spare and the equal base plate in two ends of lower top arc spare are fixedly connected with, the radius of described upper top arc spare is greater than the radius of lower top arc spare, be provided with between upper top arc spare and the lower top arc spare and be connected steel loop, be provided with dowel between lower top arc spare and the base plate.
