Abstract
The utility model discloses a kind of arch bridge, the arch bridge includes arch ring, the arch ring includes the resistance to compression area that tension area, the reinforcing bar inside the tension area are fixedly connected with the tension area, the section in the resistance to compression area uses isosceles trapezoidal structure, by the structure design in the resistance to compression area isosceles trapezoid section, increase the anti-pressure ability of the arch ring, the sectional dimension that reduces the arch ring, the consumption for reducing material and then save cost.
Description
Technical field
The utility model is related to technical field of buildings, more particularly to a kind of arch bridge.
Background technology
Arch bridge is referred to encircle the bridge as the main supporting member of structure in perpendicular, and arch bridge raises up
Curved surface, its maximum principal stress is acted on along arch bridge curved surface, is zero along the minimum principal stress of arch bridge vertical direction, and arch bridge is the base of bridge
One of body series, the long profile of construction history is graceful, and name bridge of all times spreads all over the world, occupies importantly in bridge construction
Position, it is applied to crossing highway or railway bridge, outstanding preferably crossing river channel, and because its is handsome in appearance, is also commonly used for city, scenic spot
Bridge construction.
Existing arch bridge includes the bridge floor and arch ring that bridge post and bridge post are fixed, and it is ordinary reinforced concrete to use material,
The generally rectangular cross-section section in section of arch ring or box-type section.
Existing arch bridge is larger due to the concrete amount for using, and causes the tensile resistance of arch bridge not strong, is susceptible to
Fracture, uses vertical support column mostly between the bridge floor and arch ring of existing arch bridge, this causes bearing for arch bridge horizontal direction
It is relatively low, moved left and right so as to be easily caused arch bridge, the arch ring section of existing arch bridge is larger so that the large usage quantity of material, leads
Cause the high cost of arch bridge.
Utility model content
In order to overcome the deficiencies in the prior art, mesh of the present utility model is to provide a kind of arch bridge for reducing material usage,
It can solve the problems, such as existing arch bridge high cost.
The purpose of this utility model is realized using following technical scheme：
A kind of arch bridge, the arch bridge includes arch ring, and the arch ring includes tension area, the steel inside the tension area
The resistance to compression area that muscle is fixedly connected with the tension area, the section in the resistance to compression area uses isosceles trapezoidal structure, is that the arch ring is carried
For anti-pressure ability.
Preferably, the arch bridge is prepared from using concrete, the arch bridge have more than 140MPa compression strength and
The rupture strength of more than 20MPa.
Preferably, the arch bridge use opposite sex arch section, and then the material usage of the arch bridge is reduced, give full play to various
The characteristic of material.
Preferably, the different in nature thin-walled box arch section of the arch bridge use, and then the material usage of the arch bridge is reduced, fully
Play the characteristic of various materials.
Compared to existing technology, the beneficial effects of the utility model are：By the knot in the resistance to compression area isosceles trapezoid section
Structure is designed, and increases the anti-pressure ability of the arch ring, the sectional dimension for reducing the arch ring, the consumption and then section for reducing material
About cost, causes that the compression strength and rupture strength of the arch bridge are increased additionally by using superhigh tenacity concrete so that
The anti-pressure ability of the arch ring is bigger.

Specific embodiment
Below, with reference to accompanying drawing and specific embodiment, the utility model is described further：
Fig. 1 to Fig. 2 is referred to, the utility model first embodiment arch bridge 100 includes arch ring 10, and the arch ring 10 includes anti-
The resistance to compression area 12 for drawing area 11, the reinforcing bar 13 inside the tension area 11 to be fixedly connected with the tension area 11, the resistance to compression
The section in area 12 uses isosceles trapezoidal structure, is that the arch ring 10 provides anti-pressure ability, reduces the section chi of the arch ring 10
Consumption that is very little, reducing material and then cost is saved.The arch bridge 100 uses superhigh tenacity concrete (superhigh tenacity coagulation
Native specific visible Application No. 201510026894.69, entitled " a kind of superhigh tenacity concrete and preparation method thereof "
Application for a patent for invention) be prepared from, cause that the arch bridge 100 has more than 140MPa by the superhigh tenacity concrete
The rupture strength of compression strength and more than 20MPa, with very strong anti-pressure ability and toughness, so as to the arch ring can be greatly reduced
10 sectional dimensions, the resistance to compression area 12 uses the superhigh tenacity concrete, and the tension area 11 reduces the superhigh tenacity and mixes
Solidifying soil consumption, is equipped with the reinforcing bar 13 and reaches simplified size, makes full use of the purpose of material property.
The use opposite sex arch of the arch bridge 100 section, and then the material usage of the arch bridge 100 is reduced, give full play to each
Plant the characteristic of material.
Fig. 3 is referred to, is the cross section structure schematic diagram of arch ring 10a in the utility model second embodiment, second implementation
Example is roughly the same with the structure of first embodiment, and its difference is that arch ring 10a described in the present embodiment is using different in nature thin-walled box
Arch section, the resistance to compression area 12a is fixedly connected using hollow-core construction and with the bottom of tension area 11, and then reduces material use
Amount, gives full play to the characteristic of various materials.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
