RHOMBIC FORM TRAVELLER

Brief Introduction

The rhombic form traveller has the advantages of simple structure, clear
stress, big operational space under the main frame, and easy installation
and removal, etc..
The form traveller adopts wheels with bearing while rolling forward which
reduce the frictional resistance greatly during movement; At the same
time, the stainless steel paltes are welded on the rails which reduced
the frictional resistance bewwen the sliding bearing and the rails during
movement. The combination of these reduce the movement cycle of the
form traveler by simple and convinient operation.
In terms of safety, the form traveler is equiped with walking protection
system which guarantee the absolute safety during working. It’s safe, easy
and practical.

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: What is the meaning of the bridge basket and bridge system: The main reason is because the bridge closure, temporary support, removal or addition of constraints, the system stress of bridge structure by the beam into continuous beam, or by the static structure into a statically indeterminate structure, or by N statically indeterminate structure into N+ (-) M statically indeterminate structure.

Q: Hanging basket concrete pouring construction control points: Management points:1 the concrete pouring on both sides of the beam should be symmetrical and balanced, and the unbalanced construction load should not be greater than the allowable value;2 concrete should be rapid, continuous construction, in the first pouring of concrete before the first pouring all completed;3 the bottom plate, the web and the roof are symmetrically layered, and the layer thickness should not be greater than 30cm;4 continuously change the height of the hanging basket in the process of concrete pouring;5 the quality of the installation of the prestressed channel, unobstructed inspection and plugging treatment;6 the vibration of concrete should meet the requirements of construction technology, it is appropriate to use high-frequency attachment vibrator with vibration;7 the temperature and air content of concrete in mold meet the design requirements;8 test specimens of concrete strength and elastic modulus.

Q: How to define the construction stage of continuous beam bridge hanging basket construction: Beam with three or more than three supports. Continuous beam with intermediate support

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

Q: What is the reference standard for hanging basket preloading: Before 5.1. preloading, it is necessary to fasten the tension rod of the anchor system, especially the pull rod of the back pressure system and the front cross beam system, so that the tension force can be even.5.2. preloading, with 10 tons for a level two basket symmetrical at the same time, a total of 100 tons of load on each side, each load time must be very carefully observe the guide beam elevation, and paying close attention to the hanging basket system whether there is a significant change

Q: How to deal with the broken of the cross beam of the hanging basket: Measurement of cracks can be watered with black ink, and then cut a section of cracks observed.The subsequent construction, the need to strengthen quality control, especially the control of masonry cracks in protective layer, the protective layer is too large or because most of the causes of cast-in-situ box cantilever especially should improve the understanding of crack, prestressed anchor head near the pipeline, after the proposal directly after chiseling epoxy resin mending.

Q: Construction of hanging basket: In order to achieve a good bond between old and new concrete, it is necessary to pay attention to the construction of hanging basket:(1) the pouring of concrete must be pushed forward by the front end of the hanging basket to prevent the concrete crack caused by the deformation of the concrete.

Q: Can you please list them ALL because I really need it for my book report =) thanks: Dasher, Dancer, Prancer, Vixen... er, no, wait Happy, Sleepy, Dopey, Sneezy... er, no, wait sorry, I never read it, maybe YOU should

Q: Combined with the hanging basket pouring construction process, the paper puts forward the quality control points and methods of hanging basket continuous casting box girder: Hanging basket when walking, hanging basket as far as possible to do the same time, the difference between the asymmetric distance between the hanging basket is 5cm;One must be responsible for observing the synchronization of walking, the two person is responsible for observing the operation of the walking anchor beam, the two is responsible for observing the operation of the outer die frame bearing;

Q: I'm British and traveling to Cuba whats the best form of travelers cheque to buy?: well i dont know much about cuba even thow im from the caribbean, i think they use their own money, dont know if pounds gonna work they, if i where you i would get some us money it can be spend anywhere in the caribbean and since pounds is worth more than us dollars you would be in good shape anyway hope you know spanish good luck and send me a post card.
