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:Construction of hanging basket
- Web must be maintained on both sides of the relative balance, the difference between the two sides of the concrete shall not be greater than 2m3. Two the cantilever end box Liang Bixu is symmetrically placed at the same time.
- Q:Short platform pull rope type hanging basket
- 2, rhombic hanging basket structure and technical parameters2.1 rhombic hanging basket structure and technical parametersThe rhombic hanging basket is mainly composed of a rhombic truss, an upper cross beam, a bottom mould platform, a hanging system, a walking system, an anchoring system, a side mould, an internal mould and a bracket, etc.. Technical parameters: applicable to the largest segment of 400t; maximum segment length 4m; beam height of 4.822 ~ 2.5m; for Liang Kuan 37.4m; walking for walking without balance weight; weight hanging basket (including template and support) is 170t; the hanging basket overturning stability coefficient, concrete pouring for 3.2, walking when 11.
- 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:Seven techniques of hanging basket
- Concrete pouring management should pay attention to seven technical measures10, 1 square hole. When pouring the concrete at the bottom of the roof, the roof plate can be opened on the two 50x 50 cm square hole, the concrete poured into the hole, to be completed after the completion of the concrete pouring floor sealing hole;10.2. is not overweight. When hanging basket construction concrete pouring V type pier, the difference between the pouring weight of the cross box girder and the cross shore box girder can not exceed 15 tons;10.3. symmetry. When pouring concrete in the same box girder section, it is necessary to carry out the operation of the left and right symmetry, so as to avoid the lateral displacement of the guide beam and cause the displacement of the front plane of the beam;
- Q:Construction technology of hanging basket construction:
- Short platform composite hanging basket construction: short platform composite hanging basket by hanging basket platform, tripod and servo system (including cable system, suspension system, walking system, anchorage system, horizontal support system, fine positioning system) three parts. As shown in the construction of the main girder section, under the condition of the front suspension and the pull rope, it must ensure that the front boom is under tension, and the tension value must be within the scope of the design. To install the dynamometer. Self-propelled front fulcrum hanging basket construction either truss or cable-stayed type are the fulcrum of form for the widespread use of cantilever hanging basket, the basket is a single cantilever force under negative bending moment is large, so the concrete segment length limitation. The front pivot hanging basket can make full use of the action of the stay cable and the negative moment of the cantilever is the force of simply supported positive bending moment. The pouring length and bearing capacity can be greatly improved. 1 hanging basket hanging void, at this point the anti force downward force to the hanging beam hanging basket, hanging basket and the longitudinal beams under negative bending moment.
- Q:How to deal with the cracks in the box girder
- 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:Summary of hanging basket construction:
- Pay attention to the durability of the cable, the necessary measures in the protection.
- Q:In the construction of the bridge hanging basket, the temporary prestressing force is adopted in the closing section
- Slightly under the pull, the clip is loosened, the jack to the starting point of less than the place on the clip
- Q:What's the meaning of the main truss in the basket?
- H ngli ng trussThe [brace girder] is composed of a plurality of slats of the web and the two sides of the connection of the girder
- Q:What is the meaning of the bridge basket and bridge system
- The construction of the bridge hanging basket is mainly used for continuous beam or continuous rigid frame bridge
