A traditional concrete bridge tower has a relative large size; positioning for a stiff skeleton is needed during the construction; workload for assembling and disassembling is huge; construction technology is complicated; and the traditional concrete bridge tower has poor performance of wind resistance and shock resistance. The latticed bridge tower of the concrete filled steel pipe is provided with a pier top entity segment; four tower columns are socketed on the top of the pier top entity segment; a horizontal tower column straining beam is connected to the upper parts of adjacent tower columns; a Z-shaped tower column connecting steel pipe with multi-layers is connected to the rest part between the adjacent tower columns and a latticed structure is therefore formed; the lower parts of the adjacent tower columns are provided with a horizontal supporting platform for bridge girder solidification; the tower columns are inserted in the platform; a tower girder connecting steel plate is pre-buried in the supporting platform for bridge girder solidification and is welded with a girder steel trusses of a bridge. The latticed bridge tower of concrete filled steel pipe has light weight, strong rigidity of bending resistance and great stability; the performance of shock and wind resistance is excellent; the steel pipe can be also used for a construction template of a tower body with simple construction technology and short period; little concrete exists in the steel pipe, thereby favoring on-site environment protection; and the performance of fire proofness is better than fire proofing performance of a steel structure.
Description
Technical field
the utility model belongs to transport development technical field, is specifically related to a kind of concrete filled steel tube lattice bridge tower.
Background technology
The bridge tower material of domestic current long span stayed-cable bridge adopts concrete or steel more.Concrete bridge tower is because later period maintenance expense is low, and is widely adopted.But there is size very large, from heavy, need to need to locate in larger bridge floor space, construction that stiffness steel frame, disassemble and assemble work amount are large, complicated construction technique, difficulty of construction are large, long construction period and the poor weakness of wind resistance shock stability.Although steel bridge tower has overcome above-mentioned all drawbacks of concrete bridge tower, steel exist the mechanical property defect of poor stability, for meeting structure stress and stability requirement, often to the mechanical performance index of steel, require high, need thicker sheet material, steel using amount is large, uneconomical.The defect of steel physical property aspect is that easy-to-rust and fireproof performance are poor simultaneously.And concrete filled steel tube bridge tower is by the interactional clamping force of Steel concrete, not only given full play to the advantage of bi-material, mutually made up the other side's weakness, and presented the service behaviour making new advances: bending-resistant performance is high, have fine ductile behavior, wind resistance shock stability is excellent.Due to the existence of core concrete, the apyrous of member, rustproof property are improved greatly.The steel plate thickness of steel pipe used is thinner, easily selection, and economic performance is good.Because structural member size is little, from heavy and light, wind resistance shock stability is good, and rod member batch production degree is high, has higher application value.
Summary of the invention
The purpose of this utility model is to provide the concrete filled steel tube lattice bridge tower that a kind of tower body sectional dimension is less, deadweight is lighter, the wind that can more effectively dissipate shakes energy.
The technical scheme that the utility model adopts is:
A lattice bridge tower, is provided with pier top entity section, it is characterized in that:
Entity section top, pier top socket joint is provided with four king-posts, and the top of adjacent towers intercolumniation is connected with the king-post binder of one level, and adjacent towers intercolumniation remainder is connected with the king-post joint steel pipe that multilayer is Z-shaped layout.
The bottom of adjacent king-post is provided with the tower beam consolidation support platform of level, and king-post is interspersed in the tower beam consolidation support platform of level, is embedded with tower beam junction steel plate in tower beam consolidation support platform, and tower beam junction steel plate welds mutually with the beam portion steel truss girder of bridge.
The king-post outside weld of staying cable anchorage zone is connected to anchor-hold fill plate.
The utlity model has following advantage:
The utility model utilizes the high characteristic of Concrete-filled Steel Tube Tower resistance to compression bending bearing capacity, has reduced tower body sectional dimension, has increased the effective usage space of bridge floor, thereby has alleviated dead load; Utilize steel core concrete column to there is good plasticity, dissipation wind shake energy, reduction earthquake and wind are bestirred oneself and are used the damage to bridge tower main body; Utilize lattice Concrete-filled Steel Tube Tower, for bridge tower provides larger bending-twisting rigidity, reduce the lateral deformation of structure, thereby improve the safety of bridge operation.
The utility model tower beam pier consolidated node and Sarasota anchorage node, simple structure is stressed clear and definite; The double tower body construction formwork of doing of steel pipe, construction technology is simple, short construction period; Pipe inner concrete amount is few, is conducive to on-the-spot environmental protection; Fire resistance is better than steel work; Input cost is low, and structure is advanced, and moulding brevity and lucidity, has higher application value.

The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in detail.
A kind of concrete filled steel tube lattice bridge tower that the utility model is related, the fixed system of employing pier, tower, beam, bottom is provided with pier top entity section 4, and entity section 4 top socket joints in pier top are provided with four king-posts 1, in rectangular layout, form the structure of Pylon pier consolidation.
The top that adjacent king-post is 1 is connected with the king-post binder 2 of four levels together, 1 remainder of adjacent king-post is connected with the king-post joint steel pipe 5 of multiple-layer horizontal, between the intersection end points between the king-post joint steel pipe 5 of adjacent two layers level, be connected with the king-post joint steel pipe 5 of inclination, make multilayer king-post joint steel pipe 5 form the lattice pole structure of Z-shaped layout, this form of structure makes bridge tower have larger bending-twisting rigidity and better stability, and antidetonation and wind resistance are more superior.
The bottom of adjacent king-post 1 is provided with the tower beam consolidation support platform 3 of level, king-post 1 is interspersed in the tower beam consolidation support platform 3 of level, in tower beam consolidation support platform 3, be embedded with tower beam junction steel plate 7, tower beam junction steel plate 7 welds with the beam portion steel truss girder of bridge, forms tower beam consolidation.
King-post 1 outside weld of staying cable anchorage zone is connected to anchor-hold fill plate 6, and suspension cable is directly anchored in king-post 1, and anchor-hold fill plate 6 plays diffusion weld seam internal force, reduces the effect of weld seam local stress.
Concrete filled steel tube lattice bridge tower, owing to adopting lattice tower column structure, makes it compare with concrete bridge tower, and tower body sectional dimension is dwindled greatly, and bridge floor effectively utilizes space larger, conducts oneself with dignity lighter; Bending-twisting rigidity is large, good stability; Antidetonation and wind resistance are superior; The double tower body construction formwork of doing of steel pipe, construction technology is simple, short construction period.Fixed by tower, pier, beam, strengthens the whole bending-twisting rigidity of full-bridge, has reduced the lateral deformation of bridge, has improved bridge operation safety.It is low with input cost, and structure is advanced, and moulding brevity and lucidity, has higher application value.
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, is claim of the present utility model and contains.
