Background
Compared with the traditional construction method of the cast-in-place box girder of the full-bore support, the segment assembling process adopted in the urban overhead construction highlights three advantages of environmental protection, traffic and speed: the construction is noiseless and dustless, and the influence on surrounding residents and the environment is greatly reduced; the construction method has the advantages that no support is needed to be erected on site, no concrete is needed to be poured and pounded on site, and traffic can be opened in construction, so that the pressure on the traffic caused by the construction is greatly reduced; and the construction is carried out by adopting the modules, so that the site construction speed is greatly increased. The construction method improves the technological content and the technical level of urban elevated engineering construction, and can greatly reduce the construction cost when being used in a large scale, so that the construction mode is more and more popular with people.
Wherein the section beam is part of a building structure. The segment beam comprises a top plate, a bottom plate and side plates, and the segment beam is enclosed into an inverted trapezoid shape with a hollow interior. When the segmental beam is poured, firstly, bottom web plate reinforcing steel bars and top reinforcing steel bars are bound, and hollow pipes are arranged in the bottom web plate reinforcing steel bars in a penetrating mode to serve as preformed holes of the segmental beam. And hoisting the outer template, hoisting the bound bottom web plate reinforcing steel bars onto the outer template, transversely moving the inner template to slide to the position above the bottom web plate reinforcing steel bars, installing top reinforcing steel bars, and pouring concrete to complete the construction of the segmental beam. In the splicing process of the segmental beams, in order to increase the positioning accuracy, bosses and grooves which are matched with each other in a template forming mode are respectively arranged on two sides of each segmental beam, in the splicing process, the boss of one segmental beam is inserted into the groove of the other segmental beam adjacent to the boss, and a steel bundle penetrates through the reserved hole to complete the positioning of the segmental beams.
