Product Description:

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:Characteristics of the hanging basket
The so-called hanging basket construction refers to the casting of Large Span Cantilever Beam Bridge, the use of hanging basket method, the local segmental cantilever operation. It does not need to install the bracket and do not use large crane. The hanging basket construction compared with other methods, has the advantages of light structure, simple and convenient, no heavy pressure, etc..
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: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:Construction scheme of hanging basket
The prestress design is three - direction prestressing force: 27 beams and j15.24 beams are used in the longitudinal direction, and the steel strand is used in the transverse direction of the beam, and the diameter of the steel strand is four strands of jl5.24. Tension control shall be 0.75Ryb. E2 standard for half of North Main Bridge, China Railway Bureau of the nineteenth project construction, according to the characteristics of the bridge with reference to domestic and foreign existing various types of hanging basket, main equipment selection as the diamond truss type cantilever hanging basket. The hanging plate design for railway construction design institute affiliated group corporation, has been applied to domestic Xuanzhun continuous beam construction, but the application in large span bridge construction that is the first time.
Q:What is the naut form of an inter-dimensional traveler?
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...)
Q:The post tensioned prestressed anchorage of suspension bridge can be reused?
After tensioning is fixed in the beam, can not be reused
Q:What is the meaning of hanging basket in construction
Refers to the outdoor decoration of the basket.
Q:The construction of the hanging basket of the bridge needs to be pre - pressed in each suspension section
. After the completion of the construction of this paragraph, the hanging basket symmetrical move forward a section, the next beam section construction, progressive, until the cantilever beam section of the pouring completed.
Q:Technical requirements for hanging baskets
Three the assembling and dismantling of the hanging basket shall meet the following requirements:1 hanging basket rod and the use of machinery and equipment (such as Jack, chute, hand hoist, steel wire rope, etc.), should be checked, the use of unqualified.2 hanging basket assembly should be symmetrical, timely and stable components, together as one, to prevent dumping wounding.3 hanging basket operation platform should be linked to the safety net, surrounded by a fence, there should be a special staircase.4 for the increase in the basket on the facilities (such as anti canopy, cold shed, shaft frame etc.), must be on the overall stability of the hanging basket is checked, and shall not damage the hanging basket structure and change the stress form.5 hanging basket assembly process, it is strictly prohibited to cut holes on the bolt hole, when the hole is necessary, must obtain the consent of the hanging basket design unit. It is strictly prohibited to carry out electric welding and fire on the steel bar of the finish rolling. All of the finished steel bars must be locked with double nuts.
Q:What are the key processes of hanging basket construction
The key process of hanging basket construction: 1, No. 0 block support (support) frame construction; 2, support and temporary consolidation system construction; 3, hanging basket construction
