Description

Assembled precast beam Technical Field The utility model relates to the technical field of precast beams, in particular to an assembled precast beam. Background The assembled precast beam is a structural system assembled on site by adopting industrial production, and has the core that high-efficiency construction and high-quality control are realized through a standardized process, and the assembled precast beam has remarkable advantages in building and bridge engineering. The precast beam is manufactured and molded by a die in a factory, is subjected to prestress processing, ensures the consistency of dimensional accuracy and strength, and is subjected to concrete pouring, vibration and health maintenance on a production line, wherein the surface smoothness and strength are superior to those of the cast-in-place beam. The prior assembled precast beam has the following defects that 1, the bending strength at the middle part of the prior precast beam is low, the pressure-bearing effect is not obvious, the longitudinal tensile strength, the transverse shearing resistance and the overall stability are poor. Accordingly, one skilled in the art would provide a fabricated precast beam to solve the problems set forth in the background art. Disclosure of utility model The main objective of the present utility model is to provide an assembled precast beam, which solves the above-mentioned problems in the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: An assembled precast beam comprises a precast hanger plate, a precast arch ring and a precast beam plate; The bottom of precast beam board is provided with prefabricated arch ring, the top lowest department of prefabricated arch ring and precast beam board bottom middle part department are provided with prefabricated hanger plate, the both sides of prefabricated hanger plate are provided with horizontal prefabricated plate and the top of horizontal prefabricated plate are provided with the triangle prefabricated section, the bar slide opening has been seted up to one side of triangle prefabricated section, prefabricated arch ring top inboard all is provided with prefabricated butt joint piece, the lacing wire is installed through metal connecting plate and connecting bolt to prefabricated butt joint piece one side, the bar slide opening is run through to the one end of lacing wire, lacing wire one end cover is equipped with lock nut and lock nut is located the bar slide opening outside.
