Description
Technical field
The present invention relates to a kind of urban viaduct vase pier construction field, specifically refer to overpass vase pier falsework connection
Close structure and using method.
Background technology
In the big small city of modernization, congested in traffic, building is intensive, and street is difficult to widen, therefore is carrying out city
During city's Viaduct Design, first it is also contemplated that impact to landscape, secondly will in the detailing requiments considering structure itself and intensity
While asking, also need to focus on the design of bridge, being placed on extrusion position to the Beautification design of structure, and as far as possible and peripheral edge ring
Border is uniformly coordinated, and combines together.Mechanical Builds and each spot size ratio should be mutually coordinated, and girder construction unfolds smoothness, are particular about
Its line style, infrastructure is succinctly light and handy, and permeability is good, so that overpass becomes the beautiful scenery together in city.
At present, overpass superstructure generally uses the beam type bridge construction such as box beam or t beam, and pattern is flat, dull, bottom
The bridge pier of structure to beautification overpass will play an important role, and profile similar in appearance to vase vase pier can bear top knot
The load of structure, can reserve enough spaces to surface road again, under the heavy superstructure of overpass that is narrow, constraining,
More seem attractive in appearance, smooth, spacious, allow people be rich in active, slim and graceful and pure and fresh sensation, therefore be widely used.
Vase pier is a kind of special pillarwork of comparison, is made up of linear graceful, lightly very thin queen post and bent cap,
Make a big difference with open side type entity pier stud or queen post pier stud in structure.Vase pier reinforcing bar gathers, and content is high, and curve is special-shaped
Number of steel bars and joint are many, and constructing operation process is numerous and diverse, and construction and operation stage force-bearing situation are complicated, for outward appearance and inherent matter
Amount requires very high.Just because of these particularity, existing vase pier construction generally requires sets up floor stand, constructing operation people
Member carries out pier stud and capping beam template, reinforcement installation operation and bent cap prestressed stretch-draw on floor stand, and floor stand is also simultaneously
Load-carrying members as outer outstanding curve pier stud and Coping Construction.And setting up of floor stand needs basement process, to avoid propping up
Frame sedimentation causes pier stud and the generation in bent cap crack, and floor stand occupies larger construction area space, affects work car
Current, unfavorable construction operation.
Meanwhile, the construction method of existing open side type entity pier stud or the no rack template support combination of two columned pier bent cap, such as
Pre-buried method, Hold Hoop method, suspension method etc. are not suitable for the construction of vase pier, and its major defect is: pre-buried method need to be arranged in pier stud
Bracket is set through the shaped steel of pier stud or on pier stud, using the supporter as template and support, has larger damage to pier stud,
Also affect attractive in appearance；Hold Hoop method be pier stud suitable position install anchor ear and be allowed to and pier stud clamping, using between anchor ear and pier stud
Frictional force template and bent cap weight supporting are reached pier stud, this is difficult to provide enough frictional force for very thin vase pier pier stud
Safely transmit load, also can damage the concrete on pier stud surface and affect attractive in appearance；Suspension method needs pre-buried shaped steel in pier stud,
There is provided suspension force with support shuttering and bent cap weight by pre-buried shaped steel, and the section of vase pier pier stud is little, pier stud reinforcing bar itself is close
Cloth, is curved profile it is difficult to provide the embedding space of shaped steel again, and the stress of shaped steel may make pier stud produce crack, unfavorable
Structure safety.And, for single construction with regard to pier stud, i.e. the pier stud of no bent cap, the high pier of some entities or Hollow High Pier generally adopt
No support sliding formwork or over-form construction, also has the way setting up operating platform in template, but this ease of Use platform bearer energy
Power is low, is not also suitable for the construction of vase pier tiny curve pier stud, also sets up needed for bent cap and Coping Construction because on vase pier
Bent cap support and have the bent cap stretch-draw prestressing force equipment of larger construction loads.
