Problems solved by technology

[0002] The current construction methods for the cast-in-place section of the top of the segmental beam pier are the construction of the full-wall support, the construction of the steel pipe Bailey frame and the construction of the combined support. The construction of the support is time-consuming and the turnover of the support is slow.

Embodiment Construction

[0023] refer to Figure 1 to Figure 5 , the present invention is a cast-in-place mobile formwork for the top of a segmental beam pier, comprising a number of supporting columns 1 arranged on the top surface of a prefabricated segmental beam that has been constructed, and a plurality of supporting columns 1 jointly supporting the main beam 2, the main The beam 2 is a pair of steel box girders, which are used as the main load-bearing beam of the cast-in-place mobile formwork on the top of the entire segmental beam pier. There are also several upper beams 3 horizontally erected on the main beam 2. The middle parts of each upper beam 3 are connected to the The main beam 2 is connected, and the two ends of each upper beam 3 are suspended and symmetrically provided with lower hanging beams 4 that can slide along the length direction of the upper beam 3. The upper ends of each lower hanging beam 4 are connected with the corresponding upper beam 3. The lower end of the beam 4 is suspe...

Abstract

The invention discloses a segmented beam pier top cast-in-situ movable framework. The segmented beam pier top cast-in-situ movable framework comprises main beams jointly supported by a plurality of supporting columns, and a plurality of upper crossbeams, the two ends of all the upper crossbeams are suspended in midair and are symmetrically provided with lower suspended beams capable of sliding inthe length direction of the upper crossbeams, the lower ends of all the lower suspended beams are suspended in midair and are provided with outer formwork systems, and a driving device for driving thelower suspended beams to slide is further included. According to the segmented beam pier top cast-in-situ movable framework, the outer formwork systems are constructed into a complete module throughthe supporting columns and the main beams, during construction, a segmented beam pier top can be cast only by moving the constructed module to a to-be-constructed site, after casting, the segmented beam pier top cast-in-situ movable framework can be transported to the next place and continue being used, constructing work of the outer formwork systems in the construction process is simplified, theconstruction efficiency is improved, the construction cost is lowered, and the segmented beam pier top cast-in-situ movable framework is used for the field of civil engineering.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a cast-in-place mobile formwork for the top of a segmental beam pier. Background technique [0002] The current construction methods for the cast-in-place section of the top of the segmental beam pier are the construction of the full-wall support, the construction of the steel pipe Bailey frame and the construction of the combined support. The construction of the support is time-consuming and the turnover of the support is slow. The safety risk is high, the site requirements are high, and the labor cost is high. [0003] At present, there is no cast-in-situ formwork for the top of segmental beam piers that can be used repeatedly. The formwork needs to be rebuilt every time the construction is performed. Not only is the construction efficiency low, but the construction period is long and the cost is high. Contents of the invention [0004] The object of the present invention is...
