Abstract
The invention relates to a fixing structure of arc feet of a steel corrugated plate arc arch bridge. The arc feet of the steel corrugated plate arc arch bridge are combination parts of a steel corrugated plate flexible structure and a reinforced concrete rigid structure, and the problems of stress concentration, low connecting strength, poor integral stress performance of steel corrugated plates, and the like are easily caused by the conventional connecting method. According to the fixing structure, crests and troughs at the steel corrugated plate arc arch feet are fixed in an internal groove of U-shaped groove steel by bolts; the bottom of the U-shaped groove steel and U-shaped threaded steel with a downward opening are embedded into a pier after connected; a fixing face, on the pier, of the fixing structure is perpendicular to the steel corrugated plates; the fixing structure can disperse concentrated stress at the steel corrugated plate arc feet, improve the connecting strength of the steel corrugated plates and a foundation, improve the integral stress performance of the bridge, and ensure the structural safety of the steel corrugated plate bridge; the U-shaped groove steel fixes the steel corrugated plates by the high-strength bolts; the construction quality is easy to control; the construction is more convenient and quicker; and a construction period can be saved effectively.
Description
Technical field
The invention belongs to the road traffic technical field, be specifically related to a kind of steel corrugated sheet circular arch bridge arch pin fixed structure.
Background technology
The corrugated steel pipe bridges and culverts is a kind of bridges and culverts form that adopts corrugated tubes or formed by connection, assembly unit by the corrugated arc.Adopt steel ripple bridges and culverts, passage, not only can solve climatic environment such as rainy influence the technical barrier of workmanship and construction speed, and can adapt to foundation deformation, reduces differential settlement, cushions the destruction that earthquake brings.Consider expenses such as ground processing, Foundation Design, the cost of steel ripple struction bridges and culverts will approach or more save than reinforced concrete structure, and it is fast to have a speed of application, does not need health, advantage such as be not subjected to that temperature influences.
Steel corrugated sheet culvert makes it have good stress characteristic because of the existence of axial ripple, axially with the ess-strain that radially distributes simultaneously and cause because of load, can disperse the stress of load to concentrate to a greater extent, brings into play the advantage of steel work better.Especially in bad engineering ground areas such as weak soil, expansive soil, collapsible loesses, utilize the steel corrugated board structures to build bridges and culverts and have more advantage, also have more and have broad application prospects.
Yet, steel corrugated sheet circular arch bridge arch pin is the binding site of steel corrugated sheet flexible structure and steel concrete rigid structures, conventional method of attachment causes easily that stress is concentrated, problems such as bonding strength is not enough, holistic resistant behavior difference, so can effectively address this problem the application to steel corrugated sheet bridge is exerted far reaching influence.
Summary of the invention
The purpose of this invention is to provide a kind of steel corrugated sheet circular arch bridge arch pin place that prevents and take place that stress is concentrated, bonding strength is not enough, the steel corrugated sheet circular arch bridge arch pin fixed structure of holistic resistant behavior difference.
The technical solution adopted in the present invention is:
Steel corrugated sheet circular arch bridge arch pin fixed structure is characterized in that:
The crest at steel corrugated sheet circular arc arch springing place and trough be by in the inside groove that is bolted to the U-lag steel, and U-lag steel bottom is embedded in the bridge pier place with after the U-shaped screw-thread steel that Open Side Down is connected.
The stationary plane of described fixed structure on bridge pier is vertical with the steel corrugated sheet.
The present invention has the following advantages:
Fixed structure involved in the present invention, adopt U-shaped channel-section steel by high-strength bolt corrugated sheet crest and trough to be fixed, effectively dispersed steel corrugated sheet arch springing place gets concentrated stress, strengthens bonding strength, improves steel corrugated sheet holistic resistant behavior, guarantees the structural safety of steel corrugated sheet bridge.In addition, U-shaped channel-section steel is by the fixing steel corrugated sheet of high-strength bolt, and construction quality is controlled, constructs comparatively convenient easily, can effectively save the duration.
Description of drawings
Fig. 1 is elevation of the present invention.
Fig. 2 is plan view of the present invention.
Fig. 3 is the A-A sectional view.
Among the figure, 1-steel corrugated sheet, 2-U shape channel-section steel, 3-bolt, 4-U shape screw-thread steel, 5-bridge pier.
The specific embodiment
The present invention will be described in detail below in conjunction with the specific embodiment.
A kind of steel corrugated sheet circular arch bridge arch pin fixed structure of the present invention, the crest at steel corrugated sheet 1 circular arc arch springing place and the trough bolt 3 by high strong type is fixed in the inside groove of U-lag steel 2, U-lag steel 2 bottoms are embedded in bridge pier 5 places with after the U-shaped screw-thread steel 4 that Open Side Down is connected.The U-lag steel fixedly steel corrugated sheet arch springing than the monolateral steel corrugated sheet of common angle steel bonding strength height, it is two-sided fixing to adopt U-lag steel to steel corrugated sheet arch springing to carry out, concentrated stress that can dispersed steel corrugated sheet arch springing place, strengthen steel corrugated sheet arch springing bonding strength, improve steel corrugated sheet holistic resistant behavior.U-shaped channel-section steel be embedded in the basis after the screw-thread steel that Open Side Down is connected, it is slight with being connected of basis effectively to have strengthened the steel corrugated sheet.
Described bridge pier 5 is the bridge pier of reinforced concrete soil type, and the stationary plane of fixed structure on bridge pier 5 is vertical in steel corrugated sheet 1.
It is cited that content of the present invention is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solution of the present invention by reading manual of the present invention is claim of the present invention and contains.
Claims (2)
1. steel corrugated sheet circular arch bridge arch pin fixed structure is characterized in that:
Crest and the trough at steel corrugated sheet (1) circular arc arch springing place are fixed in the inside groove of U-lag steel (2) by bolt (3), and U-lag steel (2) bottom is embedded in bridge pier (5) and locates with after the U-shaped screw-thread steel (4) that Open Side Down is connected.
