It is installed on the built-in fitting by high-strength bolt.
A kind of bridge Sarasota construction method of the invention is divided into multiple segments by carrying out king-post, is poured paragraph by paragraph
It builds, and cooperates tower crane, elevator and template system, carry out assembling reinforcement, poured.
A kind of bridge Sarasota construction method of the invention, construction technology is simple, and high in machining efficiency, the present invention effectively improves
The speed of application that the old rope of existing cable-stayed bridge is removed and new rope is set up, it is ensured that the safety for changing rope process also solves because of beam-ends
Operating space is limited, and new rope is difficult to the problem of setting up caused by can not installing pulling equipment.
Detailed description of the invention
Fig. 1 is the process flow chart of bridge Sarasota construction method of the invention.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
Refering to Figure 1, the present invention provides a kind of bridge Sarasota construction methods, comprising the following steps:
Step S1, divides king-post, and determination pours segment, pours king-tower；
Step S2 configures tower crane and elevator outside two king-posts；
Step S4 sets up template system, builds hydraulic climbing formwork；
Step S5, layer-by-layer assembling reinforcement, embedded part fixed form, casting concrete construct king-tower.
Wherein, in step S1, the king-post is divided into 22 segments, and the height of segment is 4.5m.Carrying out king-post segment
When division, buttress, three kinds of lower king-post strut intersections are comprehensively considered slowly.
In casting process, it is 4.5m that the maximum of creeping formwork of the present invention, which pours height, and the outside of king-post is arranged in tower crane, and
The brachium of tower crane is at least 45m.Preferably, a Tai Zhonglianchong section TC7013-10 type tower crane is respectively configured on the outside of 2 king-posts,
Downstream side tower crane brachium 60m, can cover steel bar meter field；Upstream side tower crane brachium 45m；To guarantee group towers work safety, 60m arm
Long tower crane is set as high-order tower, and the safe height difference between 2 tower cranes is not less than 10m.Preferably, TC7013-10 type tower crane is most
Big hoist 10t, can meet creeping formwork frame body and overarm brace lifting requirements.
The present invention respectively configures a construction elevator in each king-post, and elevator can be straight with king-post clear spacing 3m in big mileage side
It connects and is docked with climbing formwork for construction platform, attachment is set between king-post, attachment spacing is not more than 9m.
Further, template system is made of panel, wooden frame, back cord and connector in step S4 of the invention.
