Description
Technical field
The utility model relates to a kind of urban viaduct vase pier construction field, specifically refers to viaduct vase pier falsework co-ordinative construction.
Background technology
In modern large small city, congested in traffic, building is intensive, and street is difficult to widen, therefore when carrying out urban viaduct design, first the impact on view should be considered, secondly, while the detailing requiments considering structure self and requirement of strength, also need the design focusing on bridge, be placed on extrusion position to the Beautification design of structure, and coordinate with surrounding enviroment unification, combine together. as far as possibleMechanical Builds and each spot size ratio should be coordinated mutually, and girder construction unfolds smoothness, are particular about its line style, and infrastructure is succinctly light and handy, and permeability is good, thus make viaduct become the beautiful scenery together in city.
At present, viaduct superstructure generally uses the beam bridge structure such as case beam or T beam, pattern is flat, dull, the bridge pier of substructure will play important effect to beautifying viaduct, and profile can bear the load of superstructure similar in appearance to the vase pier of vase, can reserve enough spaces again to ground level road, under the superstructure that viaduct that is narrow, that constrain is heavy, 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 more special pillarwork, is made up of linear grace, lightly very thin queen post and bent cap, and structure makes a big difference with open side type entity pier stud or queen post pier stud.The vase pier reinforcing bar content that gathers is high, curve deformed bar quantity and joint many, constructing operation process is numerous and diverse, construction and operation stage force-bearing situation complicated, for outward appearance and inherent quality requirement very high.Just because of these particularity, existing vase pier construction generally needs to set up floor stand, constructing operation personnel carry out pier stud and capping beam template, reinforcement installation operation and bent cap prestressed stretch-draw on floor stand, and floor stand is also as the load-carrying members of outer outstanding curve pier stud and Coping Construction simultaneously.And setting up of floor stand needs basement process, with the generation avoiding support sedimentation to cause pier stud and bent cap crack, and floor stand occupies larger construction area space, affects Construction traffic and passes through, unfavorable construction operation.
Simultaneously, the construction method that existing open side type entity pier stud or two columned pier bent cap combine without rack template support, as pre-buried method, Hold Hoop method, suspension method etc. are not suitable for the construction of vase pier, its major defect is: pre-buried method need arrange through the shaped steel of pier stud or arrange bracket on pier stud in pier stud, using the supporter as template and support, there is larger damage to pier stud, also affect attractive in appearance; Hold Hoop method installs anchor ear at the suitable position of pier stud and make it to clamp with pier stud, utilize the frictional force between anchor ear and pier stud that template and bent cap weight supporting are reached pier stud, this is difficult to provide enough frictional force to transmit load safely for very thin vase pier pier stud, 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 cross section of vase pier pier stud is little, the reinforcing bar of pier stud own gathers, it is again curved profile, be difficult to the embedding space that shaped steel is provided, and the stressed pier stud that may make of shaped steel produces crack, unfavorable structural safety.And; single with regard to pier stud construction; namely without the pier stud of bent cap; some entity height piers or Hollow High Pier adopt without support sliding formwork or over-form construction usually; also the way setting up operating platform in template is had; but this ease of Use platform bearer ability is low, is not also suitable for the construction of the tiny curve pier stud of vase pier, because vase pier also being arranged bent cap support needed for bent cap and Coping Construction and having the bent cap stretch-draw prestressing force equipment of larger working load.
