Product Description:

UNCONVENTIONAL RHOMBIC FORM TRAVELLER

The front tranverse beam gravity height of unconventional rhombic
form traveller is betwwen the height of rhombic form traveler and
triangular form traveler. Comparing with rhombic form traveler and
triangular form traveler, it has the advantages of low gravity height,
more operational space than triangular form traveler, easy operation,
safety during walking and firm anchorage, etc..

● 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 technology of bridge hanging basket
D, the crane will be used to bridge the bottom of the bottom of the platform to lift the platform, and with the front sling, and then install the rear sling;D, installing the rear cross member and rear outer belt;E, to the basket to pre pressure to eliminate the plastic deformation, determine the size of elastic deformationF, the installation of internal and external model walking beam and to the 1# position;
Q:Characteristics of the hanging basket
Single total weight of 56.6 tons (excluding side die, die), can be poured a span of 4 meters, weight of 125 tons of reinforced concrete box girder. The hanging basket is manufactured in the factory, and the pre pressure is installed on the site. After checking the safety of the hanging basket and detecting the deflection of the guide beam, the formwork of the box girder, the binding steel bar, the installation of the corrugated pipe and the pouring concrete can be set up. After pouring a pair of beam sections, the prestressed concrete is fixed, and then the hanging basket is moved forward, and the pouring of the next section of the box beam is carried out until the end of the cantilever end.
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:Unit price analysis of hanging basket service
Do not know if you are a contractor or the contractor, is a general contractor and then do subcontracting work needs to do cost analysis
Q:What is the length of the bridge hanging basket construction?
The bridge hanging basket belongs to the cantilever construction, which can only be designed according to the bridge type, the design of the cable and the weight of the block
Q:Hanging basket construction must be both sides at the same time construction?
There are only two or three workers and simple tools and a small amount of material in the basket, the load is very small, do not require simultaneous construction. JGJ202-2010 "building construction scaffolding safety technical specifications" there is no such meaningless provisions.
Q:After the completion of prestressed tension grouting on the basket can move forward
Therefore, it is necessary to strictly control the grouting process. Do not allow the prestressed tension after the completion of the grouting on the basket forward. In reality no grouting on the hanging basket forward without accident, mainly due to the design is conservative, safety factor and other factors, to ensure the normal operation of the structure, however, once appear quality accident, it will investigate the problems existing in the construction.
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:Construction scheme of hanging basket of cable stayed bridge
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's the best form of money or payment to use in Sweden? Traveler's cheques, atm or credit card or Swedish
Bring your card (visa, mastercard) you can pay pretty much everywhere with card there.
