The invention provides a three-dimensional laser positioning device and positioning construction method for a hyperboloid building. The three-dimensional laser positioning device is composed of a laser emitting device array, rolling shafts, a rotation control module, telescopic devices and a remote control device, and can precisely position the axis of a curved building. According to the method, firstly, a curved surface where the axis of the curved building is located is divided into m parts and n layers in the horizontal direction and the vertical direction correspondingly, and the curved surface is totally divided into m*n parts; then, sufficient small panels are machined according to calculation of the height and curvature changes of all parts of the curved building; afterwards, the small panels are horizontally spliced in the axis direction on the bottommost layer and fixed by bolts, so that a formwork is formed; and in the splicing process, the three-dimensional laser positioning device is adopted for installation in a positioning mode, after installation of the formwork at the bottommost layer is completed, concrete is poured, after construction is completed, the heights of formworks on the two sides of the curved surface where the axis is located are increased by one layer, and then construction of the next layer is conducted till the height h of the building is realized.
Description
technical field [0001] The invention belongs to the technical field of optical positioning, and in particular relates to a laser three-dimensional positioning device and a positioning construction method for hyperboloid buildings. Background technique [0002] Due to the good heat dissipation performance of curved buildings, at present, the cooling towers of chemical plants and thermal power plants all adopt the shape of curved surfaces. It is much more difficult to control the cross-sectional size, displacement deviation, and verticality of concrete components in curved buildings than ordinary concrete structures, so the construction process is complicated and the construction quality is difficult to control. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a laser three-dimensional positioning device and a positioning construction method for a hyperboloid building. [0004] The technical solution adopted b...
