Vertical prefabricating construction method of cooling tower herringbone column

Abstract

The invention discloses a vertical prefabricating construction method of a cooling tower herringbone column.The method sequentially includes following processes: flattening and hardening a prefabricating yard; setting up a scaffold; mounting a formwork base; making rebars; binding the rebars; making a formwork; mounting the formwork; pouring concrete; demounting the formwork; maintaining the concrete.By using the method, prefabricating can be advanced, and construction period is shortened; the formwork can be quickly circulated and is convenient to mount, and progress is accelerated; number of formworks needing to be purchased is small, cost is saved, and the method is economical and applicable; a rebar cage is vertically mounted, so that accuracy of a position is easy to control and quality of the herringbone column is guaranteed.The method has the advantages of attractive appearance, saving of materials, high construction speed and good economic benefit.

Description

technical field [0001] The invention belongs to the field of engineering construction, and relates to a construction method, in particular to a vertical prefabrication construction method of a cooling tower's herringbone column. Tense cooling tower projects. Background technique [0002] At present, in addition to the cast-in-place construction technology, prefabrication construction technology is also used in the construction of the herringbone column of the hyperbolic cooling tower. Prefabrication is divided into two types: horizontal prefabrication and vertical prefabrication. Cast-in-place and horizontal prefabricated herringbone columns often have common quality problems such as honeycomb, pockmarked surface, pores, grout leakage, structural cracks, color difference between yin and yang, lateral bending, and deviation of steel protection layer on the concrete surface. It is difficult to deal with concrete appearance quality defects and cannot Reach the fair-faced concr...
