Embodiment
Bridge tower cushion cap overhanging type tower crane described in the utility model is made into one with specific embodiment below in conjunction with the accompanying drawings
Walk explanation.
As shown in Figures 1 to 3, bridge tower cushion cap overhanging type tower crane described in the utility model includes bridge tower cushion cap 1, by pre-
Embedded part 2 is fixed on two steel structure outer columns 3 and steel structure inner column 4 on bridge tower cushion cap 1, and fixed Zhi Yugang structures outer column 3
With the load-bearing frame on 4 top of steel structure inner column.Steel structure outer column 3 be located at 1 edge of bridge tower cushion cap and with steel structure inner column 4 and be in square
Shape is arranged, and the load-bearing frame includes being fixedly connected with adjacent steel structure inner column 4 and 3 top of steel structure outer column and bridge is stretched out in one end
A pair of of foundation longitudinal beam 5 at 1 edge of tower cushion cap and the basic crossbeam 6 for connecting two foundation longitudinal beams 5.The middle part of steel structure outer column 3 is respectively
Equipped with choosing outer raker beam 7 and the interior leg brace beam 8 that end and the top of adjacent steel structure inner column 4 are connected outside foundation longitudinal beam 5, and with it is outer
The intersegmental part that crosses of raker beam 7 and interior leg brace beam 8 is filled with reinforced Concrete 9.
, can be from if directly tower crane is directly supported on bridge tower cushion cap in the work progress of cable-stayed bridge pylon
Support of the special bored concrete pile as tower crane is poured in cushion cap periphery.But the upper space of bridge tower cushion cap is more narrow and small, this
Class tower crane needs to avoid all kinds of constructing structures on cushion cap in setting, prevents construction from disturbing, also to meet force request.
Above-mentioned tower crane is arranged on bridge tower cushion cap edge, and tower crane is loaded on basic the outer of crossbeam and chooses end, and is in bridge tower
On the outside of cushion cap, all kinds of constructing structures on bridge tower cushion cap can be so avoided to greatest extent, avoid construction from disturbing.The steel of homonymy
There is provided inside/outside raker beam between structure outer column, steel structure inner column and basic crossbeam to be reinforced, and steel structure outer column and inside/outside
The section that crosses of diagonal brace wraps up in concrete structure for the internal steel filled with reinforced Concrete, so contributes to strengthen tower crane overall structure
Stability and at the key node of load transmission structure carry out reinforcement so that for tower crane provides consolidate support.
It is readily apparent that at the same time, above-mentioned tower crane may also be disposed on other permanent engineering structures, such as various cushion cap classes
In structure, arrange that this kind of tower crane will not occupy larger cushion cap space and smaller to the interference of construction, due to without
Engineering structure periphery pours special bored concrete pile and supports, which can be applied to the severe region of waterborne and geological conditions
In engineering project, and construction cost is relatively low.
Steel structure outer column 3 is located at the middle part of 1 one long side of bridge tower cushion cap in embodiment, and steel structure inner column 4 is by bridge tower cushion cap 1
Side, foundation longitudinal beam 5 extend along vertical bridge to extension, basic crossbeam 6 along direction across bridge.
It is equipped with below interior raker beam 8 between adjacent steel structure outer column 3 and/or steel structure inner column 4 and horizontally or obliquely extends
Connecting rod 10.Contacting between adjacent steel structure outer column and steel structure inner column can further be strengthened by introducing connecting rod, so as to hold
Weight frame provides more stable support.In embodiment due to steel structure outer column 3 and interior leg brace beam 8 and outer raker beam 7 joint and
It is closer to the distance with the joint of two connecting rods 6 of the top, reinforced Concrete 9 also extend further downward to steel structure outer column 3 with
The intersection of above-mentioned two connecting rods 6, to further improve the structural strength of 3 load transmission critical section of steel structure outer column, improves
Its compressive property.
Horizontal cross brace 11 is equipped between steel structure outer column 3 and steel structure inner column 4.
Vertical bridging 12 is equipped between two steel structure outer columns 3 and between two steel structure inner columns 4.
Contacting between steel structure outer column and steel structure inner column can further be strengthened by introducing horizontally and vertically bridging, make to stand
Intercolumniation forms stable grid-system, easy to the transmission of load between column so that for top load-bearing frame and tower crane provide it is more steady
Fixed support.
The load-bearing frame further includes fixed frame and shelves crossbeam 13 in a pair chosen outside two foundation longitudinal beams 5 in section.Two are shelved
The both ends of crossbeam connection corresponding with 4 tie points of tower crane bottom respectively, so as to effectively strengthen between load-bearing frame and tower crane tie point
Contact, easy to the transmission of tower crane internal load.
Steel structure outer column 3 and steel structure inner column 4 are steel pipe column in embodiment, interior leg brace beam 8, outer raker beam 7 and load-bearing
Frame is made of the Two bors d's oeuveres I-steel containing stiffener plate, and horizontal cross brace 11, vertical bridging 12 and connecting rod 10 are then adopted
With relatively thin shaped steel material, it is fixedly connected between various steel rod elements with welding manner.1 edge of bridge tower cushion cap is needed in corresponding positions
Anchor plate is installed as built-in fitting 2, steel structure outer column 3 and 4 bottom of steel structure inner column and anchor plate weldering to connect.Carry out tower crane
Welding it is assembled before need both ends welding diaphragm in 3 internal reinforcement concrete of steel structure outer column, 9 filled section and open up on the outer wall to pour
Orifice, treats after the completion of tower crane integral assembling placing reinforced Concrete 9 again.Reinforced Concrete 9 can install tower crane solid after fully curing
Determine to shelving on longeron, the tower crane can overall pulling down and circulating repetition use after the completion of bridge tower construction.
