A construction method of fair-faced concrete with special-shaped space curved surface

Abstract

A special-shaped spatial curved surface water concrete construction method comprises the steps as follows: (1) template preparation; (2) template assembly; (3) template installation; (4) reinforcing steel bar binding; (5) water concrete preparation; (6) water concrete transporting, pumping and laying; (7) water concrete pouring; (8) concrete vibrating; (9) concrete curing; (10) template removing; and (11) water concrete repairing. The invention provides the special-shaped spatial curved surface water concrete construction method, and the problem that special-shaped spatial curved surface water concrete construction is difficult is solved. In terms of a tower, the 93-meters-high structure is beyond the reach of a commonly-used car pump, and construction is difficult to implement. A fixed pump is adopted for transportation in the invention, and the problem that the structure is beyond the reach of the car pump is solved.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a construction method of fair-faced concrete with special-shaped space curved surfaces. Background technique [0002] Fair-faced concrete, also known as decorative concrete, gets its name because of its great decorative effect. It belongs to one-time pouring molding, without any external decoration, and directly uses the natural surface effect of cast-in-place concrete as the finish. Therefore, it is different from ordinary concrete. Apply one or two coats of clear protector to look very natural and dignified. [0003] The purpose of this project is to build the tower and air traffic control building. The peripheral wall of the tower is designed as hyperboloid fair-faced concrete, with a thickness of 160mm and a height of 93m. Gradient surface with multi-arc radius. The east and west gables, overhanging eaves and part of the parapet of the aviation ma...
