TRIANGULAR FORM TRAVELLER

Brief Introduction

Trianngular form traveler has the advantages of low gravity of front
trancerse beam, safe & easy operation, easy fixing, and safty during
walking, etc..
During the designing of the form traveller, we always provide
different modes of traction, such as hydraulic pushing mode or
pulling mode, and chain hoist mode, etc. to the constructors for their
choice.
The design of the form traveller could be divided into two types:
external sliding girder and self-moving exteral formwork according to
de construction conditions. When the site condition does not allow
to remove the form traveller at the closure part which have to go
backwards to segment, the second type is suggested.

Advantage

● Low gravity of front trancerse beam

● Applicable to large-scale stay-cable cantilever casting bridge with wide bridge deck

● Safe & easy operation, easy fixing, and safty during walking

● Big operational space under the main frame, and easy installation and removal

Q: 80m hanging basket construction section of how to pull tension longitudinal reinforcement? At this point both ends of the concrete, how to pull ah: Continuous beam is internal chamber, it is possible to access the internal chamber from both sides of the pier, which is convenient for operation after checking; besides first side span closure to midspan, we at the time of construction, span closure has no inside tooth block tensioned, longitudinal prestress only long the length is at the ends of the tension, and not in Never mind.

Q: What is the meaning of the bridge basket and bridge system: The construction of the bridge hanging basket is mainly used for continuous beam or continuous rigid frame bridge

Q: What are the key processes of hanging basket construction: 5, construction of prestressed beam shape control; 6, 7; and the closure above and the construction of system transformation are met according to arrangement of students problems in practical work and, for reference, if there is a problem, please timely communication.

Q: Hanging basket construction which test items: Wire rope, safety rope, safety lock, some local arms also need to do.

Q: Summary of the hanging basket construction: 2 the girder structure system of the main girder structure system can be divided into four different systems according to the combination of the girder tower and the cable tower:Floating system: Tower Pier tower girder girder consolidation, separation, in addition to support at both ends, all the rest of the cable suspended, this system does not provide effective support for the transverse beam, to the temperature shrinkage and creep force structure, the cross section deformation and internal force changes smoothly, uniform stress, but must be in the cantilever construction in the tower at the temporary consolidation.Support system: Tower Pier tower girder girder consolidation, separation, set the vertical support in the tower, a three span continuous beam or cantilever beam with elastic support, the latter is in a cross hinge or a hanging hole, a hanging hole to a certain length, in order to avoid the side load, resulting in hanging hole excessive tilt.Tower beam consolidation system: the tower beam is fixed and supported on the pier, the stay cable is an elastic support, which can be used for continuous beam or cantilever beam.Rigid frame system: the beam pier is mutually consolidated to form a rigid structure with multi point elastic supports.3 overview of cable-stayed bridge construction process: the construction of cable-stayed bridge erection method in general there are three common methods: support method, push method and cantilever construction method. The first two methods used in the early construction of cable-stayed bridge, the cable-stayed bridge grew up in modern, especially from the tower to the cantilever construction on both sides of the multi span cable-stayed bridge with missile, inclined cable segment support.

Q: Hanging basket construction must be both sides at the same time construction? Are there any rules? What is the norm?: Please rest assured that the calculation of the load of the bridge structure is huge, just hanging basket this little temporary construction load is not a piece of cake!Only from the point of gravity load on the bridge, there is no problem. But whether the requirements of the construction process, construction organization, or starting or starting from the schedule to rush period, it should be different.

Q: The hanging basket is the main equipment of the cantilever pouring construction of the bridge: Hanging basket is the main equipment of cantilever pouring construction of bridge,

Q: Hanging basket in the construction of the 2 block construction is also need to press it: First, the height of the test results. In line with the requirements do not pre pressure, followed by hanging basket construction 0# block is the most important, pre pressure pouring. Down to the basket pre pressure, that is, 1# block, in the continuous beam hanging basket in addition to 0# block 1# is the most important, in the 1# pre pressure when the basket has been removed from the non elastic deformation, so no need to hang the basket that is 2# block pre pressure.

Q: How is the prestressed steel bar in the hanging basket method? Is the length of each section of the tension of the prestressing tendons, or tensioned T - shaped steel beam length of prestressed tendons?: The general construction of prestressed concrete box girder with cantilever hanging basket construction scheme, the box girder hanging basket, formwork, reinforced after installation, concrete pouring, the concrete reaches the design strength value after tensioning the beam segments each segment between the prestressed tendons (tendons connected according to the design of short or long beam the layout of the beam.) after grouting, demolition template

Q: You know how space travelers are astronauts and time travelers are crononauts? Well, what is the naut form of an inter dimensional traveler? (Obviously in fiction).: Internaut? ;) I don't think one exists yet. You could try making it up. If Cosmos is the universe and inter-dimensional travel is travelling between different parallel universes, maybe it should be Cosmonaut (though the Russians already took that one...)
