Description
Technical field
The utility model relates to the improvement of steel construction overline bridge, particularly relates to for T-shaped road junction all directions intercommunication requirement, if
The meter large span space three-dimensional intersection chevron shaped overline bridge of steel construction.
Background technology
T-shaped road junction is the meet of heavy traffic main line, belongs to areal of traffic concentration, and motor vehicles are many, wide variety, speed
Degree is fast, especially increases sharply at society personnel street flow of crossing on and off duty, and people's car embraces, and causes " intestinal obstruction " of traffic, therefore People's Bank of China sky
The construction of bridge is imperative.During the narrow space of place, existing steel construction overline bridge, owing to span centre need to arrange bridge pier, it is impossible to uses,
Can not meet and each require to the intercommunication in beeline.In order to make at limited T-shaped road junction, place, space, it is achieved " people's car
Separate ", it is ensured that have a good transport and communication network and traffic safety, conscientiously alleviate traffic jam issue, be highly desirable to improve overpass design,
Solve motor vehicles and the present situation of conflicting of pedestrian's street crossing, improve region transportation situation.
Utility model content
Technical problem to be solved in the utility model is the design large span space three-dimensional intersection chevron shaped overline bridge of steel construction,
This overline bridge considers the intercommunication of T-shaped road junction all directions, for the low problem of large span overpass natural frequency of structures,
Column arranges lattice column, and span centre sets rotary island and solves natural frequency of vibration problem；Moment of flexure effect at the bottom of the post that the loads such as temperature produce is big
Cause basic engineering difficulty problem, novelty at the bottom of firm structure column install LYQZ type hold-down support, release superstructure
The moment of flexure effect producing due to loads such as temperature, optimizes basic engineering.
For solving the problems referred to above, the large span space three-dimensional described in the utility model intersection chevron shaped overline bridge of steel construction, its
It is characterised by: it includes steel box girder used by structure of main bridge, steel box girder top width 5.4 meters, sets diameter at three-dimensional infall
Circular hole equal to 3m, to be used as shunting, sets a length of 3.8m, the platform of a width of 5.4m, platform at firm structure column with the girder just place of connecing
In the range of perfusion C40 slightly expanded concrete, the firm structure column under platform is four 1.2m × 1.0m steel reinforced concretes combination rectangular columns, each
Connect to strengthen the rigidity of structure and globality with twice 0.5m × 0.5m crossbeam between firm structure column, be respectively provided with LYZQ at the bottom of each post solid
Determine bearing.
The utility model has the advantage that compared with existing steel structure footbridge (1) successfully solves major urban arterial highway
T-shaped road junction arranges intercommunication overpass, is the intercommunication realizing T-shaped road all directions, and bridge horizontal layout is Y type, this spanning
In be not provided with bridge pier, make to pass through under bridge broad view, and 3 steel box-girder hexagonal angles each other, for mitigating spanning span centre weight and minimizing
The impact that the stream of people interweaves, center sets the circular hole of an a diameter of 3m, and the central point of circular hole is equal to the horizontal range at 3 bridge pier centers
It is 31.5 meters, allow pedestrian reach all directions at crossing with distance the shortest；(2) large span overpass structure self-vibration frequency is improved
Rate, the requirement of the natural frequency of vibration current specifications to be met of large span overpass, by Calculation Anaysis for Tunnel Structure, use lattice column to increase
The rigidity of strong structure and globality, the natural frequency of vibration of structure meets the requirement in specification, the natural frequency of vibration being not less than to 3HZ；(3)
The moment of flexure effect solving the load generations such as temperature causes greatly the problem of basic engineering difficulty, owing to spanning degree is big, and degree of statical indeterminacy
Many, so the moment of flexure Benefit Transfer that superstructure produces due to loads such as temperature is big, this will cause the infrastructure of structure to be thrown
Money increases.In the design process, novelty at the bottom of firm structure column install LYQZ hold-down support, release superstructure due to temperature
The moment of flexure effect producing Deng load, optimizes basic engineering.
Large span space three-dimensional of the present utility model intersection steel construction chevron shaped overline bridge version is reasonable, the bridge after building up
Air, of tremendous momentum, elegant in appearance, grand is developed in beam moulding, and overall technology level is higher, has a extensive future.Lanzhou
New Guang Dong Victory Hotel of city overpass have employed the large span space three-dimensional intersection chevron shaped overline bridge of steel construction, successfully solves Lanzhou
The traffic problems in major trunk roads Shuangcheng door location, it is achieved the intercommunication of T-shaped road junction all directions, will greatly facilitate the pedestrian of both sides
Cross street, it is achieved people's car separates, and makes road traffic more smooth and easy, improve the efficiency of road operation, it is ensured that pedestrian crosses street safety.
