Description
Technical field
The present invention relates to the technical field of science of bridge building, specifically a kind of Novel rod of Large-Span Cantilever assembly steel bridge
Part.
Background technique
Long-span steel arch bridge or steel truss girder bridge generally use the construction method of free cantilever erection, and loop wheel machine is usually wanted in work progress
It walks on main arch or main truss chord member.After construction, on main arch or main truss chord member to need that tool car is arranged convenient for conserving.
Meanwhile in order to meet the requirement such as landscape, health monitoring, built-in fitting is welded, in structure inevitably to install Landscape Lamp
Or sensor etc..If these constructions and the built-in fitting of operation phase are directly welded on the main plate of steel construction, will necessarily be right
Steel construction base material generates damage, causes stress raisers.In addition, previous construction hoist track needs after the completion of construction
It is cut off using thermal cutting technique in building site.The steel plate stress of LARGE SPAN STEEL BRIDGE is larger, when these stress concentration points and thermal cutting
Heat affecting can become the security risk of structure.If built-in fitting is welded at assembled scene, steel construction base material can be also destroyed
Coating influences the durability of structure.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of Large-Span Cantilevers to spell
Steel loading bridge rod piece construction.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of Large-Span Cantilever assembly steel bridge rod piece, it is characterised in that the Large-Span Cantilever assembly steel bridge rod piece include mainly by
Power component and secondary primary structure member, the main bearing member and secondary primary structure member are arranged parallel, and along rod length side
To extension, and secondary primary structure member is connected by the way of being fixedly connected with main bearing member, and main part of the force meets master
The requirement of body structure stress, secondary part of the force meets construction hoisting and operation tool car walking requires, while meeting built-in fitting
Welding requirements.
In general, main bearing member is using being rectangle, polygon, circular cross-section or truss, secondary part of the force is used
I-shaped, inverted T-shaped, π tee section, the connection of main member and secondary member is using welding, and weld seam should detect a flaw to meet
Secondary primary structure member is reliably connected during bridge operation with main bearing member, and secondary primary structure member is as main stress
The supplement of component, reduces the stress of main bearing member, and the sectional area of secondary primary structure member is about main bearing member sectional area
3% ~ 7%, therefore the stress that can reduce main bearing member is about 3% ~ 7%.
Further, secondary primary structure member is used for the Crane Rail of Construction crane, runs the walking track of tool car, simultaneously
Built-in fitting welding as affiliated facility.Main bearing member and secondary primary structure member should be completed to connect into steel construction processing factory
One entirety, and unify coating in factory, it needs after lifting construction and operation phase affiliated facility welding to secondary at the scene
The coating damaged portion of primary structure member is repaired, need to be using reliably to the secondary member of the tool car track as the operation phase
Measure (such as oiling) prevents secondary primary structure member from corroding.
The main bearing member should ensure that and be not counted in it to main stress using secondary primary structure member as load
Meet structure under the premise of the bearing capacity contribution of component in the safety for constructing and runing the phase.
The secondary primary structure member should ensure that it meets the safety under the action of construction and operation load.
The main bearing member and secondary primary structure member should be welded to connect in steel construction processing factory, to guarantee to connect
Connect quality.
The main bearing member and secondary primary structure member need to carry out unified coating in factory after completing connection, existing
The coating damaged portion to secondary member is needed to repair after field lifting construction and operation phase affiliated facility welding, to work
It need to prevent secondary member from corroding using reliably measure (such as oiling) to run the secondary member of the tool car track of phase.
Specifically, the rod piece is the main truss top boom of steel truss girder bridge, and main bearing member is rectangular section, by four pieces of bands
There is the plate put more energy into be welded, secondary primary structure member uses π shape section, is welded on the top plate of main bearing member, constructs
The loop wheel machine used in the process is walked on rod piece using the secondary primary structure member of rod piece as track；Safety in work progress is anti-
Guard rail rod, construction monitoring foil gauge are welded on secondary primary structure member.
Further, to the end of all constructions and after all Accessory Members weld, secondary primary structure member is carried out
Coating reparation, it is ensured that it is not corroded in the operation phase.
Further, the tool car during runing longitudinally is walked using secondary primary structure member as track along bridge, complete
At the maintenance of bridge top boom and top bracing；Health monitoring equipment and built-in fitting during operation are welded on secondary stress structure
On part；The landscape lighting apparatus and built-in fitting of operation phase is welded on secondary primary structure member.
The present invention sufficiently combine design, construction, operation, management, main part of the force be structure stress main body, it is secondary by
Power component is the function body of construction and operation curing period.The design can reduce the construction equipment and fortune of construction time to greatest extent
Damage of the site weldings such as the built-in fittings such as illumination, the guardrail of battalion's phase to main bearing member, while secondary part of the force again can be with
As the supplement of main part of the force, reduce the stress of main part of the force.The structural system can reach prefabrication most
Bigization avoids site welding or bolts the influence to main stressed member, so that reliability of structure is improved, in cantilever jointing steel
There is higher promotional value in arch bridge and steel truss girder bridge.Compared with prior art, rod piece of the invention construction fully considers that structure is set
Meter, construction, operation management life cycle management.The safety and reliability of increased structure improves the durability of structure.
