Q:Can the vertical prestress of the hanging basket be tensioned after the subsequent section construction?

Prestressed concrete structure, before the load in advance, put pressure on it, in the external load when the concrete tensile stress compressive stress produced in order to offset or reduce the load due to the tensile stress, the structure used in the normal circumstances does not crack or crack late.

Q:There are transverse prestressed steel strand in the middle beam, the bridge has longitudinal steel strand, and the vertical line is finished steel. I would like to ask the next three pull sequence

The general situation is to pull the first part of the prestressed steel strand

Q:What are the characteristics of the "hanging basket" bridge? What are the advantages and characteristics of such a bridge?

The bridge structure stress is divided into: the suspension system (such as cable-stayed bridge and suspension bridge); arch system (such as: deck arch bridge, arch bridge, arch bridge); beam system (such as: simply supported girder bridges, continuous girder bridges, continuous rigid frame bridge)

Q:What is the meaning of "hanging basket" in building construction

It is a platform surrounded by railings, suspended on the roof of the wall with a rope

Q:Construction process of hanging basket

In summary, the construction process of the hanging basket construction management, said the following simple way: the hanging basket can be moved forward in place to install the bottom mold and the mold to install the bottom plate and the side rib reinforced pipe, and reserved installed within the mold to install roof reinforcement and pipe, concrete pouring and curing the reserved to wear pre stress steel beam and tension anchor a pipe grouting.

Q:80m hanging basket construction section of how to pull tension longitudinal reinforcement? At this point both ends of the concrete, how to pull ah

Continuous beam is internal chamber, it is possible to access the internal chamber from both sides of the pier, which is convenient for operation after checking; besides first side span closure to midspan, we at the time of construction, span closure has no inside tooth block tensioned, longitudinal prestress only long the length is at the ends of the tension, and not in Never mind.

Q:What is the length of the bridge hanging basket construction?

As for the weight of the piece, the largest piece of the current piece is about 350 tons.

Q:Construction scheme of hanging basket

The construction scheme of rhombic truss type hanging basket: a brief introduction of the main structure of the main bridge of the North Branch bridge of Nanjing Second Yangtze River Bridge is 90+3*l65+90 (m) of the five span prestressed concrete continuous box girder. The main span of 165m is the first in the same type of bridge in china. According to the design requirements, the construction method needs to use cantilever pouring construction technology and then through the closure and system conversion into continuous beam

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
