Description
Technical field
The present invention relates to Bridge Design and technical field of construction, cross segment structure and construction in particular to a kind of new Sarasota
Method.
Background technology
Bridge cable tower is mainly used in the middle of large span stayed-cable bridge, suspension bridge, generally tall and slender structure, and its version is more
Sample, generally has " inverted Y-shaped ", " A types ", " H types ", " brilliant ", " flower vase type " etc., central " inverted Y-shaped ", " A types ", " brilliant ",
" flower vase type " exist therefrom king-post progressively cross in receive the structure of upper king-post strut, the structure is usually defined as that " Sarasota crosses
Section ".Sarasota is divided into two kinds of forms, armored concrete Sarasota and steel construction Sarasota, therefore is also divided into concrete for the section that crosses
Two kinds of structure and steel construction.Conventional steel bar concrete Sarasota, the section that crosses typically adopt reinforced concrete structure pattern, make various
Different moulding (common to have circular arc, ellipse, parabolic type etc.).As armored concrete Sarasota commonly uses prefabricated and cast-in-place two
Kind, prefabricated component weight is larger, selects requirement higher crane gear, substantially without application；Cast-in-place concrete is used as concrete pylon
Main application direction, as its feature is suffered from the drawback that：(1) at the section that crosses, the pumping height of concrete is high, single coagulation
The side's of pouring amount of soil is big, high to the pumping equipment performance requirement of concrete；(2) cross a section modeling structure complexity, the more section that crosses
Template system adopts spelling template, and construction quality and appearance are poor, arrange the sizing structure of steel die of certain rigidity, installs difficult
Spend big and high cost；(3) construct hole reserved and reinforcing bar pre-buried etc., complex process, with certain operation difficulty；(4) hand over
Section of converging is typically in superaltitude, needs to set up the measure such as the console of greater stiffness or high-altitude corbel type arch support, together
When to remove the support difficulty larger, with operational risk is big, the duration consumes the features such as long, material consumption is big.
The content of the invention
Present invention aim to solve the deficiency of above-mentioned background technology, there is provided a kind of new Sarasota cross segment structure and
