Abstract
The utility model relates to a steel corrugated plate circular arc arch bridge arch foot fixing structure. A steel corrugated plate circular arc arch bridge arch foot is the portion where a steel corrugated plate flexible structure is combined with a reinforced concrete rigid structure, and a conventional connecting method can easily cause stress concentration, low connecting strength and poor overall stress performance of steel corrugated plates. According to the steel corrugated plate circular arc arch bridge arch foot fixing structure, the crest and the trough on the steel corrugated plate circular arc arch bridge arch foot are fixed to the interior of an inner groove of U-shaped box iron through bolts, and the bottom of the U-shaped box iron is embedded into a pier after being connected with a U-shaped deformed steel bar with a downward opening; a fixing surface, on the pier, of the fixing structure is perpendicular to a steel corrugated plate. The steel corrugated plate circular arc arch bridge arch foot fixing structure can effectively disperse stress concentration on the steel corrugated plate arch bridge arch foot, improve connecting strength of the steel corrugated plate and a foundation and overall stress performance of a bridge and guarantee structure safety of the steel corrugated plate bridge. Furthermore, because the steel corrugated plate is fixed by the U-shaped box iron through the high-strength bolts, construction quality is easy to control, construction is convenient and fast to conduct, and the time limit for a project can be effectively shortened.
Description
Technical field
The utility model belongs to the road traffic technical field, is specifically related to a kind of steel corrugated sheet Arch Bridge arch springing fixed structure.
Background technology
The corrugated steel pipe bridges and culverts is a kind of bridges and culverts form that adopts corrugated tubes or by the corrugated arc, by connection, assembly unit, formed.Adopt steel ripple bridges and culverts, passage, not only can solve the rainy technical barrier that waits Climatic Effects workmanship and construction speed, and can adapt to foundation deformation, reduce differential settlement, the destruction that the buffering earthquake brings.Consider the expenses such as ground processing, Foundation Design, the cost of steel ripple struction bridges and culverts will approach or than reinforced concrete structure, more save, and it is fast to have a speed of application, does not need health, the advantage such as be not subjected to that temperature affects.
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 to a greater extent the stress of load to concentrate, and brings into play better the advantage of steel work.Especially, in the bad engineering ground such as weak soil, expansive soil, collapsible loess area, 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 Arch Bridge arch springing is the binding site of steel corrugated sheet flexible structure and steel concrete rigid structures, conventional method of attachment easily causes the problems such as stress is concentrated, bonding strength is not enough, holistic resistant behavior is poor, 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 utility model is to provide a kind of steel corrugated sheet Arch Bridge arch springing fixed structure that prevents that steel corrugated sheet Arch Bridge arch springing place generation stress from concentrating, bonding strength is not enough, holistic resistant behavior is poor.
The technical scheme that the utility model adopts is:
A kind of steel corrugated sheet Arch Bridge arch springing fixed structure is characterized in that:
Crest and the trough at steel corrugated sheet circular arc arch springing place are bolted in the inside groove of U-lag steel, and U-lag steel bottom, with after the U-shaped screw-thread steel that Open Side Down is connected, is embedded in the bridge pier place.
The stationary plane of described fixed structure on bridge pier is vertical with the steel corrugated sheet.
The utlity model has following advantage:
The fixed structure that the utility model is related, adopt the U-lag steel by high-strength bolt, corrugated sheet crest and trough to be fixed, effectively dispersed steel corrugated sheet arch springing place obtains concentrated stress, strengthens bonding strength, improves steel corrugated sheet holistic resistant behavior, guarantees the structural safety of steel corrugated sheet bridge.In addition, the U-lag steel is by the fixing steel corrugated sheet of high-strength bolt, and construction quality is easily controlled, constructs comparatively convenient, can effectively save the duration.
Description of drawings
Fig. 1 is the utility model elevation.
Fig. 2 is the utility model plan view.
Fig. 3 is the A-A sectional view.
In 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
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of steel corrugated sheet Arch Bridge arch springing fixed structure described in the utility model, the crest at steel corrugated sheet 1 circular arc arch springing place and the trough bolt 3 by high-strength is fixed in the inside groove of U-lag steel 2, U-lag steel 2 bottoms, with after the U-shaped screw-thread steel 4 that Open Side Down is connected, are embedded in bridge pier 5 places.U-lag steel fixedly steel corrugated sheet arch springing is higher than the monolateral steel corrugated sheet of common angle steel bonding strength, adopt U-lag steel to steel corrugated sheet arch springing to carry out two-sided fixing, 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.The U-lag steel be embedded in basis after the screw-thread steel of being connected connects, effectively strengthened the steel corrugated sheet with basic be connected slight.
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 utility model is not limited to embodiment, and the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model manual, be claim of the present utility model and contain.
