Abstract

The invention discloses a construction method for single-piece hoisting of an aluminum alloy vault of a large vertical storage tank. The aluminum alloy vault is fitted to the top of the large vertical storage tank in a covering manner; the aluminum alloy vault comprises a support frame and an outer mask covering the support frame; the support frame comprises a central connector and a plurality of ring beams distributed outside the central connector from inside to outside; the outer mask comprises a middle mask and a plurality of circumferential masks; the outermost one of the circumferential masks is an outer circular mask. The construction method includes: 1, assembling the aluminum alloy vault and a tank bottom; 2, mounting a tank top lift, namely, mounting the lift used for hoisting the required vault, outside the upper portion of the tank which is cylindrical; 3, hoisting the aluminum alloy vault; 4, fixing the aluminum alloy vault; 5, mounting the outer circular mask. The construction method has the advantages that steps are simple, the design is reasonable, construction is easier, construction is efficient, construction effect is good and the aluminum alloy vault can be hoisted to the large vertical storage tank simply and quickly.

Description

technical field [0001] The invention relates to a hoisting construction method, in particular to an integral hoisting construction method of an aluminum alloy vault of a large vertical storage tank. Background technique [0002] The aluminum alloy vault of a large vertical cylindrical storage tank is mainly composed of a supporting frame, a cover plate, fasteners, sealing bead and accessories. It has the characteristics of light weight and corrosion resistance. The supporting frame is assembled from multiple structural beams. Nowadays, there are a large number of large vertical cylindrical storage tanks used in oil depot projects, and the volume of large vertical cylindrical storage tanks used is generally greater than 5000m 3 , if the volume is 10000m 3 、20000m 3 There are more vertical cylindrical storage tanks. At present, when installing and constructing the aluminum alloy vault of a large vertical cylindrical storage tank, the installation method usually adopted is t...
