Large-span beam construction method based on hot-rolled high-strength steel bars

Abstract

The invention relates to a large-span beam construction method based on hot-rolled high-strength steel bars. The method comprises the following steps that S10, surveying and setting-out is carried out, specifically, surveying is carried out according to a design drawing, and marking is carried out at a construction position by using an ink line; S20, column construction is carried out, specifically, the steel bars of frame columns are bound, then forms of the frame columns are installed, and concrete is poured into the forms; S30, steel pipes are erected, and a form support is built; S40, beamconstruction is carried out, specifically, a beam bottom form is installed, then the steel bars are bound on the bottom form, after binding is completed, side forms of a beam are installed, and finally concrete is poured into the forms; S50, concrete curing is conducted, specifically, concrete is covered with a material, and regular moisturizing and wet curing are conducted; and S60, the forms and supporting frames are dismantled, specifically, all the forms and all the supporting frames are dismantled in sequence. The construction method has the effects of standard construction, high construction efficiency and high strength.

Description

technical field [0001] The present application relates to the field of beams, in particular to a construction method for long-span beams based on hot-rolled high-strength steel bars. Background technique [0002] A beam is a building component that bears vertical loads and is mainly subjected to bending. [0003] The patent with the notification number CN201202217Y discloses a prefabricated concrete beam, which includes a beam body composed of steel bars and concrete wrapped with steel bars. The top surface of the beam body has a plurality of stirrups whose bottom ends are embedded in the concrete and whose top ends are exposed to the top surface, and A plurality of main reinforcements fixedly connected with a plurality of stirrups, the main reinforcement is arranged along the length direction of the beam main body, and there is a gap between the bottom of the main reinforcement at the lowest position and the top surface of the beam main body. [0004] With regard to the ab...
