RHOMBIC FORM TRAVELLER
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.
● 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: How does the prestressed tensioning in the construction of the bridge hanging basket?
- After pouring a concrete, such as the strength of the aging period, the tension of a paragraph, and then continue to the next section of constructionSpecific construction process and other prestressed construction process the same
- Q: Hanging basket construction can bind steel
- At the intersection of steel, the application of 0.7~2.0 mm wire, according to figure 8 staggered or cruciform manner by butting, butting
- Q: After the completion of prestressed tension grouting on the basket can move forward
- [prestressed grouting is not completed after the hanging basket forward is not allowed] duct grouting has two main purposes: one is to protect the steel wire no rust, prolong the service life of structure, so the grouting be plump and compact; two is as a medium in relaxation steel strand, to transfer beam a part of stress.
- Q: In the construction of the bridge hanging basket, the temporary prestressing force is adopted in the closing section
- Almost the same procedure. Install jack, Jack extended a distance, not fully stretched
- Q: Vertical embedding of hanging basket
- . The steel wire mesh of the embedded steel bar and the roof must be fixed firmly
- Q: Are there any hanging baskets on both sides of the hanging beam 0
- In the 1# pre pressure when the basket has been removed from the non elastic deformation, so no need to hang basket that is 2# block pre pressure.
- Q: How to deal with the cracks in the box girder
- 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: Is hanging basket equipment special equipment? Need to record it?
- Special equipment regulations on safety supervision of special equipment is the safety of life, the risk of large boilers, air compressor and the air storage tank, tunnel construction hoisting machinery (construction elevator, tyre crane, crawler crane, gantry crane, tower crane, bridge machine), hanging basket construction equipment etc..
- Q: Can the vertical prestress of the hanging basket be tensioned after the subsequent section construction?
- In order to improve the service performance of prestressed structure, during the construction to the structure of pre applied stress structures of pre compressive stress can be wholly or partially offset load caused by tensile stress, avoid structural damage. Commonly used in concrete structure, concrete structure under load is before, in advance to put pressure on it to make it in the outside load when the concrete tensile stress compressive stress produced in order to offset or reduce the load due to the tensile stress, the structure in the case of normal cracks or crack late.
- Q: I would like to know that each piece of the construction of the hanging basket is connected by way of the whole as a whole, I always think of each section is a section of tension.As you said, the steel strand is the length of the whole beam, but how to form the whole concrete?
- Each section of the pouring, the prestressed pipe to stay in that, when the tension, only pull the section of prestressed reinforcement. Those who like long, without tension will not wear.
