Ring beam construction method based on tool type shaping concrete ring beam formwork structure

Abstract

The invention relates to a ring beam construction method based on a tool type shaping concrete ring beam formwork structure. The ring beam construction method mainly comprises the construction steps of formwork body installation, U-shaped frame installation, jacking screw rod adjustment, limiting steel bar adjustment and ring beam pouring. After a formwork body is temporarily fixed, a U-shaped frame is installed in a limiting vertical groove in the outer side of the formwork body; the formwork body is further jacked from the outer side through a jacking screw, and the formwork body is tightlypushed from the inner side through a limiting steel bar; and then pouring of a ring beam is carried out. The construction is convenient and fast, the structure is stable, slurry leakage or mold expansion is not likely to happen in the pouring process, and the poured ring beam is flat and smooth in surface; the components can be recycled, the problems that a formwork body is low in rigidity, the formwork supporting process is complex, the stability of the formwork body is poor, the recycling and reusing rate is low, and the construction effect of the ring beam is poor in the traditional opposite-pull screw wood formwork supporting technology are solved, and certain economic and technical benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of concrete ring beam construction in brick-concrete structure buildings, and in particular relates to a ring beam construction method based on a tool-type stereotyped concrete ring beam formwork support structure. Background technique [0002] In brick-concrete structure buildings, ring beams are set up to meet the requirements of seismic design. The traditional formwork system for ring beam construction, such as the invention disclosed by the application number 201520351086.2, is a masonry ring beam formwork for filled walls, which includes square logs arranged on both sides of the ring beam. Between the beam and the formwork, there is a tension bolt penetrating through the ring beam along the middle part of the formwork, and a through-tube is sleeved on the tension bolt passing through the ring beam. The formwork reinforcement effect is good, while ensuring the verticality of the formwork; the material i...
