Embodiment Construction

[0031] The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

[0032] like figure 1 As shown, a U-shaped steel structure formwork is used for pouring concrete beams, especially suitable for the construction of large-span and high-altitude concrete hollow box girders. The U-shaped steel structure formwork includes: a bottom steel plate 10 and two side steel plates 20, The bottom steel plate 10 and two side steel plates 20 are spliced ​​together to form a U shape; several lower H-shaped steel beams 30 are arranged at intervals above the bottom steel plate 10 along the length direction of the bottom steel plate 10, and the lower The web 31 of the H-shaped steel beam 30 is perpendicular to the bottom steel plate 10; several upper H-shaped steel beams 40 are correspondingly arranged above the lower H-shaped steel beam 30, and the upper part of the upper H-shaped steel beam 40 Th...

Abstract

The invention discloses a pouring construction method of concrete beams. Construction is conducted through a U-shaped steel-structure formwork. The method includes the following steps of S1, manufacturing the U-shaped steel-structure formwork, and hanging the U-shaped steel-structure formwork through steel corbels; S2, anchoring reinforcing steel bars of the concrete beams at a support in the U-shaped steel-structure formwork; S3, pouring concrete on a bottom steel plate of the U-shaped steel-structure formwork to complete pouring of the concrete bottom plate; S4, pouring concrete on two side steel plates of the U-shaped steel-structure formwork to complete pouring of the concrete beams; S5, pouring concrete on a plurality of upper H-shaped steel beams of the U-shaped steel-structure formwork to complete pouring of a concrete top plate. A reinforcement cage can be rolled on the ground in advance, the concrete beams can be directly formed in the formwork through pouring after the steel-structure formwork is hung, and therefore the construction quality can be effectively ensured, no scaffold needs to be erected any more, the construction period can be shortened, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a construction method for pouring concrete beams using a U-shaped steel structure formwork. Background technique [0002] At present, the pouring of concrete beams generally requires the erection of scaffolding, especially when pouring high-altitude and long-span concrete beams, the erection of scaffolding takes a lot of time. Contents of the invention [0003] The purpose of the present invention is to provide a construction method for pouring concrete beams, which can complete the rolling of steel cages on the ground in advance, and after the steel structure formwork is hoisted, the concrete beams can be directly poured inside the formwork, which can not only effectively ensure The construction quality is improved, and there is no need to erect scaffolding, which can shorten the construction period and have good economic benefits. [0004] In order to achieve the a...
