The invention discloses a laser three-dimensional positioning device and positioning construction method for a curved surface building. The laser three-dimensional positioning device consists of a laser emission device, a rolling shaft, a rotating control module, a telescopic device and a remote control device. The axis of the curved surface building can be positioned precisely. The positioning construction method comprises the following steps that firstly, a curved surface where the axis of the curved surface 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 divided into m*n parts totally; then the enough number of a plurality of small face plates needing to be machined is calculated according to the height and curvature changes of each part of curved surface building; then the small face plates are horizontally spliced in the axial direction on the lowest layer, then fixed by using bolts and form templates; and in the splicing process, positioning and installing are conducted through the laser three-dimensional positioning device, after the installing of the template of the lowest layer is completed, concrete pouring is conducted, after construction is completed, the height of the templates on the two sides of the curved surface where the axis is located are heightened by a layer, and then construction of a next layer is conducted until the height reaches the height h of the building.
Description
technical field [0001] The invention belongs to the technical field of optical positioning, and in particular relates to a laser three-dimensional positioning construction method for curved 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] The technical solution adopted by the device of the present invention is: a laser three-dimensional positioning device for curved buildings, including a laser emitting device, a remote control device, and a movable mechanical arm; [0004] The plurality of lase...
