The raising of construction technique, more and more Urban Bridges are using high standard, large span, the new tie connected as city
The trip of people provides facility.Urban construction is with " dredging stifled " for target, and the traditional Large Span Bridges construction in China is with reinforced concrete
Soil is primary building material, and build is long in time limit, and production material is seriously polluted, " is made stifled " in the construction period, to civic production, life
Life birth life seriously affects, and greatly reduces the Happiness Index of city dweller.
Existing cable-stayed bridge head tower is based on box-type section, interior filling concrete, and based on pressing, moment of flexure control exists king-tower stress
Compared within the scope of small magnitude.
Invention content
Utility model aims to solve above-mentioned technical problems, provide a kind of lattice-type steel truss pylon cable-stayed bridge, change
Philanthropist's tower force modes, to achieve the purpose that make full use of steel strength.
The utility model proposes a kind of lattice-type steel truss pylon cable-stayed bridge, including tower pier, the tower that is connected on tower pier
Column and the tower top crossbeam for being connected to king-post top, the king-post are two, and the king-post includes 4 steel box columns, the king-post
It is interior to be equipped with T-shape rib, it is equipped with line-styled stull and " X " type diagonal brace support construction between the steel column, the support construction is by 4
Steel box column is linked to be entirety, and the tower top crossbeam is steel truss type structure, and two independent king-posts are linked together.
Further embodiment, the tower pier are reinforced concrete structure, and the sections Ta Dun are in single box single chamber section.
Further embodiment, tower pier top portion are equipped with the tower pier crossbeam of enhancing king-post contact.
Further embodiment, the tower top crossbeam are equipped with horizontal brace.
Further embodiment, the tower pier are connect with king-post using PBL key connection modes.
Further embodiment, the king-post are steel construction king-post.
This programme has the beneficial effect that：
1, make the force modes of the complexity such as former king-tower pressure, curved be changed to draw, based on pressure, steel strength is made full use of to reach
Purpose.The head tower is simple in structure, and stress is clear, modern design.
2, this programme truss king-post front face area is small, can be effectively improved wind load lower king-post strut galloping stability；In addition, king-post hinders
The reduction of wind area, can effectively shorten length of airtight area after king-post, improve environment, increase travel safety.Meanwhile king-post
Form of construction work is various, both can after the completion of integral assembling vertical transfer it is in place, also can segment lifting, site welding is bolted, increases not
With the alternative of arrangement and method for construction under construction environment.
3, it is equipped with the support construction of line-styled stull and " X " type diagonal brace between king-post, can effectively shorten king-post slenderness ratio, increases
Strong king-post stability.Simultaneously, it is possible to increase king-post bending stiffness reduces king-post lateral deformation.
4, tower pier and king-post are two kinds of different construction materials, and combined area stress is complicated, using PBL keys, can effectively enhance
The connection reliability of two kinds of different materials.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention will be further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
As shown in Figures 1 and 2, a kind of lattice-type steel truss pylon cable-stayed bridge of the utility model proposition, including tower pier 1,
The king-post 2 that is connected on tower pier 1 and the tower top crossbeam 3 for being connected to 2 top of king-post, the king-post 2 are two, and the king-post 2 wraps
4 steel box columns are included, T-shape rib is equipped in the king-post 2, line-styled is equipped between the king-post 2（Stull 4）" X " type（Tiltedly
Support 5）Support construction is steel structural form, increases intensity and reliability.4 steel box columns are linked to be whole by the support construction
Body, the tower top crossbeam 3 are steel truss type structure, and two independent king-posts 2 are linked together.
As shown in Figures 2 to 5, the tower pier 1 is reinforced concrete structure, and 1 section of tower pier is in single box single chamber section.
1 top of the tower pier is equipped with the king-post crossbeam 11 of enhancing king-post contact.Tower top crossbeam horizontal brace is additionally provided on the tower top crossbeam 3
6.The tower pier 1 is connect with king-post 2 using PBL key connection modes.The king-post 2 is steel construction king-post.
The relative position relation of tower pier 1 and king-post 2 influences environment huge.King-post 2 uses steel construction, such as attached drawing 3
It is shown, 4 mutually independent steel box columns connected by king-post stull 4, diagonal brace 5 it is integral, with pressure, it is curved based on steel column stress
Mode change at draw, pressure based on king-tower entirety stress, smaller windward side can be effectively improved the galloping under king-post wind load.King-post
2 can ground complete integral assembling after vertical transfer it is in place, reduce working at height risk.If being limited by construction site condition, can also incite somebody to action
King-post is vertically divided into several segments, after segment lifting is in place can site welding, be bolted, segment standardization, be conducive to
Unit in charge of construction's batch micro operations, light tower hoist, that is, Liftable can effectively save engineering cost.Tower top crossbeam 3 shown in attached drawing 4 can be effective
Improve king-tower stress, makes king-post overall deformation.
The utility model makes the force modes of the complexity such as former king-tower pressure, curved be changed to draw, based on pressure, to reach abundant profit
With the purpose of steel strength.The head tower is simple in structure, and stress is clear, modern design.This programme truss king-post front face area is small, can
It is effectively improved wind load lower king-post strut galloping stability；In addition, the reduction of king-post wind resistance area, the calm head of district after king-post can be effectively shortened
Degree improves environment, increases travel safety.Meanwhile king-post form of construction work is various, it both can vertical transfer be just after the completion of integral assembling
Position, also can segment lifting, site welding is bolted, and increases the alternative of arrangement and method for construction under different construction environments.
