Problems solved by technology

[0003] At present, in the construction process of the thin shell structure, the curvature of each formwork is different except for the round thin shell. The difficulty and accuracy required for the erection of the formwork frame, the manufacture, processing and installation of the formwork are relatively high, and the construction process is complicated. relatively large demand

Embodiment Construction

[0017] 1. Raw material control

[0018] (1) Mixing water: Drinking water is mostly used as mixing water in the project, and acidic water with a pH value of less than 5, water with a sulfate content exceeding 1% of the water volume, and water containing harmful substances that affect the normal condensation and hardening of cement are not allowed. use.

[0019] (2) Cement: In order to ensure the solidification time of spray deposition pouring and shotcrete and the compatibility with the quick-setting agent, the cement used should have high strength, good impermeability and durability, and the spray deposition mold pouring should preferably use the label 52.5 , 52.5R, high-strength Portland cement, for sprayed concrete, the high-strength Portland cement with a label of 42.5 or 52.5 and above should be preferred. All cement should be tested for strength identification before use. A batch of cement should be used up at one time, and cement from different manufacturers cannot be m...

Abstract

The invention discloses a construction method of a thin shell with a thin-shell structure and relates to a reinforced concrete construction method of a thin shell with a thin-shell structure. Aiming to reduce the workload of producing, mounting and stripping a framework, the construction method comprises the following construction steps of: (1) hanging and paving a combined body of a concrete gridded attached carrier for deposing and pouring and reinforcing ribs on a prestress cable net, binding the attached carrier, the reinforcing ribs and the cable net by using the reinforcing ribs with a concrete bearing structure; and carrying out spraying and concreting to generate a form shell of the formwork for pouring concrete; and (2) carrying out spraying concreting on the generated form shell to finish the construction of the thin shell with the thin shell structure. The construction method is simple, can save a large amount of labor force and physical resources and has favorable comprehensive technical and economic performances.

Description

technical field [0001] The invention relates to a building construction method, in particular to a reinforced concrete construction method suitable for a thin shell of a thin shell structure. Background technique [0002] The thin-shell structure in building construction is a thin-walled structure with a curved surface. Most of the materials are reinforced concrete. The thickness of the shell surface can be made very thin, generally 1 / 600 of the radius of curvature. The shell can make full use of the strength of the material and at the same time bear Combined with the two functions of enclosure, a beamless column structure with relatively large span space can be built. In actual engineering, the cutting and combination of space surfaces can also be used to form buildings with unique and novel shapes that can adapt to various design shapes, such as The thin shell structure of the Sydney Opera House is very beautiful in shape. The construction method of the thin shell structu...
