Problems solved by technology

[0004] The quality requirements of the fair-faced concrete structure of this project are Class C, and the fair-faced concrete on the part of the arc hyperboloid is more difficult; the building's exterior structure is complex, and the building is a high-rise building with a small construction area. As far as the tower structure is concerned, The height of the structure is 93 meters, which cannot be reached by common automobile pumps, so it is difficult to realize; as far as the fair-faced concrete itself is concerned, it is not conducive to the transportation of pumps

Embodiment Construction

[0025] A construction method for fair-faced concrete with special-shaped space curved surfaces, comprising the following steps:

[0026] (1) Formwork preparation: panel material selection, blanking, nesting, seaming and square steel keel processing;

[0027] (2) Assembling formwork: the assembly of the square steel dragon skeleton body and the assembly of the panel;

[0028] (3) Installation template;

[0029] (4) Binding of steel bars: Vertical steel bars should be corrected before pouring concrete. The joints of wall steel bars should be welded or lapped, and the joints should be staggered. When binding the net, the hooks of the reinforcement wires should be bent into the concrete, and the steel bars connected to the wall should not be too long. When the steel bars conflict with the tension bolts, follow the principle of avoiding the tension bolts for the reinforcement bars;

[0030] (5) Preparation of clear-water concrete: The raw materials selected according to the mix r...

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...
