Product Description:

STAYED-CABLE CANTILEVER TRAVELLER

Stayed-cable cantilever traveller is applicable to large-scale stay-cable
cantilever casting bridge with wide bridge deck, heavy and long segment. Most of
the componants concentrates on bottom frame and walking system. It has no main
frame, at the same time, the lift is done by the stay-cable of the bridge. Comparing
with other types, the sigle weight of stayed-cable cantilever traveller is heavier.

●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: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:Under what circumstances the use of hanging basket construction
If you are in need of some relatively flat, bridge bridge, scaffording height is not high, can try to use the full scaffold construction, all with full scaffold construction, so that the safety, economy and engineering quality is easy to control.
Q:Production and installation of hanging basket
8..5. fixation. In the process of pouring, the anchor plate is easy to loose 1 shift. Therefore, the screws must be fixed on the head template o8.6. positioning. The positioning of the corrugated pipe should be based on the bottom of the corrugated pipe, according to the curve coordinates of the prestressing tendon in the design.8.7. welding. In the process of pouring the bellows lands will be produced in the floating phenomenon, therefore, the bellows in place, can be tied to a "n" type in steel pipe, welded steel bracket and firmly, spacing is generally 60 cm, bracket welding in the stirrups, stirrup below advance real pad o
Q:What should be paid attention to in the construction of cast in place box girder of long span bridge hanging basket
Preventive measures: with good insulation performance wood template (preferably professional manufacturers), have a certain thickness and stiffness of the template surface to be coated with special treatment, release agent, to ensure the quality of cast-in-place concrete.The contents of the above are based on the actual work of the students to meet the problem of finishing, for reference, if there is a problem, please timely communication.
Q:80m hanging basket construction section of how to pull the longitudinal tensile reinforcement
Internal tooth block! You look at the construction plans will know.
Q:Can you list all the characters form The Time Traveler's Wife and their descriptions?
Dasher, Dancer, Prancer, Vixen... er, no, wait Happy, Sleepy, Dopey, Sneezy... er, no, wait sorry, I never read it, maybe YOU should
Q:Is it necessary to measure the strain value after prestressing?
Stretching process:(1) post tensioned precast box girder is made of prefabricated field or precast factory prefabricated box girder, and then transported to the site erection; (2) the post tensioned prestressed cast-in-place box girder bridge, is in direct casting box girder and prestressed tension. Cast in situ prestressed box girder, according to the support structure is different, the full frame pouring box beam and hanging basket construction pouring box beam. The hanging basket construction is the use of suspension facilities, segmental mold hanging and binding steel corrugated pipe, installation, concrete pouring, wearing steel strand, stretching and grouting, the completion of a segmental box girder, a segmental box girder, until the completion of the entire construction segment.
Q:When hanging blue construction, middle span closure, why must the counterweight
First of all, the basket itself has weight. The weight of the hanging basket has some influence on the stress of the bridge, especially the construction state
Q:The effect of hanging basket
Hanging basket construction technology, although it is the first time, but was successful
Q:What is the meaning of hanging basket in construction
Refers to the multi-storey or high-rise buildings outside the wall decoration workers operating the role of the basket, there are two kinds of automatic lifting and manual lifting, hanging basket hanging mechanism stability should be calculated
