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:Hanging basket assembly quality control point: The composition of the basketHanging basket bearing system, bottom formwork system, side formwork system (inside and outside), walking system, rear anchorage system. A hanging basket is made up of two triangles, each of which bears the weight of the beam. Taking into account the processing capacity of the construction site, the main beam, the sliding beam, the upper beam and so did not use a reasonable truss structure, and the use of steel structure.

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:How to deal with the broken of the cross beam of the hanging basket: If the structure cracks, while continuing to the direction of the development of the proposed use of epoxy resin modified cement mortar repair.If the surface layer of cement slurry is too thick, it is recommended to clean the surface, re repair.

Q:Short platform pull rope type hanging basket: The construction scheme for main bridge superstructure: installation of steel pipe column bracket in the cap on the box girder construction 0, No. 1 block on the bracket; 0, 1 complete block construction after the erection of rhombic hanging basket, piecewise symmetric cast until the completion of the No. 18 block construction (including 7 ~ 17 block cable block), forming the largest cantilever structure of T, and then by the side span to middle span by span symmetric closure.

Q:What are the innovative points of hanging basket construction: 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:Hanging basket construction continuous beam, the adjacent fast is how to connect, such as Block 0 and block No. 1: 1, have been pouring section (such as 0# block) of the end of the concrete to do all the processing of cutting hair.2, the first of two adjacent segments (such as 0# and 1#, 0# and 1 '#) all the longitudinal bars between the (steel web comprises a bottom plate, the roof and corresponding welding together).

Q:Construction technology of hanging basket construction:: The construction of a steel cable-stayed bridge, most of the factory welding process, transported to the site, with the crane as a whole lifting, or block lifting, in place after the formation of high-strength bolts.Two construction of concrete cable-stayed bridge with cast-in-place and precast assembly and other combinations of construction technology. 1 the installation elevation of the hanging basket should be in strict accordance with the designed value.

Q:Hanging basket construction must be both sides at the same time construction? Are there any rules? What is the norm?: Hanging basket is hanging on the structure of the tool type scaffolding, its movement by crane or tower crane

Q:The hanging basket is the main equipment of the cantilever pouring construction of the bridge: The hanging basket is the main equipment of the bridge cantilever pouring construction, usually consists of five parts, namely: the main truss, lifting system, formwork system, walking system, anchor system

Q:Seven techniques of hanging basket: 10.5. tube. When the concrete is vibrated, we should pay attention to avoid the bellows to prevent the vibration rod from leaking;10.6. to nap. Because of concrete pouring, the surface still paving asphalt concrete, in order to enhance the bonding between the deck and asphalt layer layer of political government must firmly on the concrete surface roughening treatment:10.7. maintenance. After the concrete pouring, maintenance to improve the strength of concrete and prevent the formation of fine cracks, has an important role. Therefore, water conservation should not be less than seven days.
