Embodiment Construction
[0040] The following is attached Figure 1-4 The application is described in further detail.
[0041] The embodiment of the present application discloses a construction method for hydraulically lifting the steel inner cylinder 2 of a chimney and flipping it. refer to figure 1 and figure 2 , a chimney steel inner tube hydraulic lifting and flip-chip construction method is to install the steel inner tube 2 composed of a plurality of standard sections 21 in the outer tube 7 of the chimney, and connect the steel strand 72 through a plurality of hydraulic lifting jacks 71, and the steel strand Line 72 gradually lifts up the standard section 21 for installation. The devices used in the installation procedure include transport tools, height alignment components 3, rotating components 4 and stabilizing components 5. The height alignment components 3 are connected to the rotation components 4. The transport tools and The height alignment component 3 is connected, and the stabilizat...

The invention relates to the technical field of building construction, in particular to a hydraulic lifting and upside-down construction method for a steel inner cylinder of a chimney. The hydraulic lifting and upside-down construction method comprises the specific steps that the steel inner cylinder is installed in an outer cylinder of the chimney, the steel inner cylinder is composed of a plurality of standard knots, S1, the standard knots are transported to the positions under the standard knots installed in the outer cylinder through a transport tool; S2, the standard knot is lifted to the position under the installed standard knot through a height alignment assembly, and the standard knot abuts against the installed standard knot; S3, the standard knot is rotated through a rotating assembly and is in threaded connection with the installed standard knot; S4, the connected standard knots are welded and fixed; and S5, the remaining standard knots are sequentially installed according to the same method. The method has the advantages that a lower standard not is in threaded connection with an upper standard not, and the adjacent standard knots are in threaded connection, so that the finally connected steel inner cylinder is straight.
Description
technical field [0001] The present application relates to the field of building construction technology, in particular to a construction method for hydraulic lifting and flipping of a steel inner cylinder of a chimney. Background technique [0002] Industrial chimneys are large in size and high in height. They are usually composed of an outer outer cylinder and an inner steel inner cylinder. The steel inner cylinder is spliced by multiple standard sections. Therefore, it takes a lot of money to install the chimney steel inner cylinder. A lot of manpower and time. [0003] Among the related technologies, the Chinese application document with the application number 201510834739.9 discloses a chimney steel inner tube hydraulic lifting and flipping construction method, which includes the following steps: S1: Install a computer control cabinet, a hydraulic pump station and a hydraulic lifting jack on the steel platform 71 ; make the standard section of the steel inner cylinder...
