Embodiment Construction
[0016] The present invention will be described in detail below in combination with specific embodiments.
[0017] The present invention relates to a steel shell of a continuous beam with a rotating body, which is provided with a shell 1 with the same shape as the external surface of the beam, and is connected to the end of the beam body 4 of the continuous beam with a rotating body, see figure 1 and figure 2 The housing 1 includes a bottom plate and side plates protruding upwards on both sides of the bottom plate, and the shape of the end part is also the same as that of the beam body wing. The longitudinal width of the casing 1 can be adjusted according to the needs of the working space. The inner wall of the housing 1 is welded with a transverse partition 3 perpendicular to the bottom and side plates of the housing 1, and the transverse partition 3 is a bent strip. The quantity of diaphragm 3 can be adjusted according to the longitudinal width of housing 1, as image 3 T...

The invention relates to a closure section steel shell of a turning continuous beam. Influences of construction of a turning construction closure section on an existing line below are severe. According to the closure section steel shell, a shell body exactly the same as the outer surface of a beam body in shape is arranged and connected to the end portion of the beam body of the turning continuous beam. The shell body comprises a bottom plate and side plates which are arranged on the two sides of the bottom plate and extend upwards, the inner wall of the shell body is provided with a transverse partition board vertical to the bottom plate and the side plates in a welded mode, the transverse partition board is a bent long-strip-shaped plate, the two faces of the transverse partition board are provided with longitudinal reinforcing ribs vertical to the transverse partition board, a connection steel plate is welded between the shell bodies of the end portions of the two turning continuous beams to be closured, the connection steel plate is a bent plate, the shape of the bent plate is the same as that of the shell bodies, and the connection steel plate and the shell bodies at the two ends constitute a sealed operation whole. The closure section steel shell serves as an outer die, bears self-weight of a beam section and construction load and forms a combination beam with concrete to be involved in structure stress, meanwhile, construction of the closure section is carried out in a steel box which is completely sealed, and influences of construction of the closure section on the existing line are greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of bridge structure construction, and in particular relates to a steel shell of a swivel continuous beam closing section. Background technique [0002] At present, the construction of the closing section of the continuous beam adopts the closing hanger as the carrier, and the continuous beam is closed after the formwork is supported on the closing hanger, but the construction of the closing section above the existing railway or road requires the existing railway or road. Pipe shed protection. The construction of the pipe shed will interfere with the existing railway or highway. Especially the swivel continuous beam, in order to reduce the interference with the existing road or railway, the swivel construction is adopted, but the construction of the closing section has a great influence on it, which has a certain impact on the superiority of the swivel construction. Contents of the invention [0003] The...
