Embodiment Construction

[0079] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0080] The invention provides a construction method for a large-span multi-curvature special-shaped curved roof, which is suitable for the construction of free-form surfaces, such as irregular shapes like robes. The roof adopts a hollow reticulated shell structure, which is formed by assembling aluminum alloy rods. This construction method uses SAP2000 software to analyze the force of the overall model of the supporting frame to determine the structure, size, and spacing of the supporting frame. At the same time, MIDAS (GEN ) The finite element analysis software conducts overall force analysis, stability check calculation and working condition analysis review on the slip track, unit reticulated shell and steel lattice column. Through the 1:1 full-scale simulation experiment, the unit assembly and block sliding system are tested to verify the fe...

Abstract

The invention relates to a construction method of a special-shaped curved surface roof with a large span and multiple curvatures. The construction method comprises steps as follows: regional division is performed according to the shape of the special-shaped curved surface roof; structural rod pieces are assembled in a bulk area, and a first lattice shell structure is formed; structure units are hoisted in a unit mounting area, and a second lattice shell structure connected with the first lattice shell structure is formed; sliding tracks are laid on an operating platform in a sliding mounting area; lattice shell units are transported to the sliding mounting area through the sliding tracks for assembly, then a third lattice shell structure connected with the first lattice shell structure and the second lattice shell structure is formed, and accordingly, a lattice shell roof is formed; support pillars are arranged below the lattice shell roof, and the operating platform is dismounted. According to the construction method, the mounting area is divided, a mounting method combining bulk assembly of components, unit hoisting and lattice shell sliding is adopted, and the construction method has the advantages that the construction period is shortened, the construction cost is saved and the construction quality is improved.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a large-span multi-curvature special-shaped curved roof. Background technique [0002] With the rapid development of our country's social economy and the continuous progress of science and technology, construction technology has also entered a high-speed development mode. The super-high, irregular and large-scale building structures have brought new challenges to the innovation and development of construction technology. As a scientific and advanced form of large-span space structure, the aluminum alloy structural system has been used more and more at home and abroad for its many advantages such as corrosion resistance, light weight, high-precision prefabrication standardization, and fully assembled construction. [0003] For the installation of multi-curvature and special-shaped surface structural systems, due to the variety of components and compl...
