Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0036] Below, with figure 1 The special-shaped thin shell of the shown concrete structure is taken as an example to illustrate the construction method of the present invention. in figure 1 The three-dimensional model shown is a BIM model of a theater. The construction method of the present invention will be described below with reference to the accompanying drawings. BIM software is commonly used in the construction field. The letter axis and the number axis are also two mutually perpendicular axes for positioning in the architectural field.

[0037] The construction method of the special-shaped thin shell of the concrete structure of the present embodiment, carries out following steps successively:

[0038] (1) Spatial positioning, spatial positioning is divided into two steps: t...

Abstract

The invention discloses a method for constructing a special-shaped thin shell of a concrete structure. The method includes the following steps of firstly, conducting spatial localization, setting up a three-dimensional model of the special-shaped thin shell, sectioning the model to form slices, setting up a database of coordinates of all the slices, taking intersection points of the horizontal cross section and the sectioning face as control points, forming a database of coordinates of the control points, and conducting surveying and lining; secondly, erecting a formwork, wherein the formwork comprises a supporting frame arranged inside, a main keel arranged on the supporting frame, an auxiliary keel arranged on the main keel, and a formwork, and the auxiliary keel is covered with the formwork; thirdly, conducting reinforcing bar engineering, namely, setting reinforcing bars outside the formwork, and forming a reinforcement fabric; fourthly, conducting concrete construction, namely, pouring concrete on site in different areas and different sections to form the thin shell; fifthly, removing loads from the body of the thin shell and conducting monitoring at the same time. The formwork which forms the special-shaped thin shell after construction is conducted is formed with modeling wood, and the shape and the stress condition of the formed special-shaped thin shell of the concrete structure meet the design requirements.

Description

technical field [0001] The invention relates to the technical field of special-shaped shell construction, in particular to a construction method for a special-shaped shell of a concrete structure. Background technique [0002] With the development of the times, more and more public buildings, such as theaters, stations, and museums, adopt unique shape designs to achieve beautiful and unconventional effects. For example, China's CCTV building, the Bird's Nest and so on. Compared with common regular shapes such as cuboids and spheres, these buildings are collectively called special-shaped buildings. Many special-shaped buildings adopt special-shaped thin-shell structures, and the special-shaped thin-shell structures have always been dominated by steel structure construction, that is, the thin-shell structures are composed of steel. However, for the construction of concrete structures with special-shaped thin shells, there is a lack of relevant theoretical and practical exper...
