Installation method of umbrella-shaped roof structure

Abstract

The invention provides an installation method of an umbrella-shaped roof structure, aims at solving the technical problems that an existing installation construction method is inconvenient due to the fact that the umbrella-shaped roof structure is complex in shape, large in component number, large in high-altitude splicing difficulty and high in precision requirement, and relates to the technical field of construction of large space structures of constructional engineering. An umbrella-shaped roof is divided into 20-30 umbrella-shaped unit structures, the adjacent umbrella-shaped unit structures are connected into a whole through long-strip-shaped wave-shaped roof steel beams, and the installation method comprises the following steps of (1) performing modular assembly on the ground; (2) installing a temporary support; (3) performing hoisting in units; and (4) dismantling the temporary support and monitoring structural deformation: unloading a sandbox support, dismantling the temporary support and monitoring the structural deformation. According to the installation method, the construction period is effectively shortened, the construction precision is improved, and meanwhile the installation quality of other related structures attached to the umbrella-shaped roof structure is improved.

Description

technical field [0001] The invention relates to the technical field of construction of large-scale space structures in construction engineering, in particular to a method for installing an umbrella-shaped roof structure. Background technique [0002] The demand for large space in public buildings is increasing, and the application of large space structures is becoming wider and wider. The construction of large-scale spatial structures and the technologies used often reflect the level of a country's construction technology. Some large-scale, novel and technologically advanced special-shaped large-scale spatial structures have become an important symbol of a country's economic strength and construction technology level. In the past few decades, special-shaped large-space steel structures have achieved breakthroughs in structural forms, materials, design methods, and construction techniques. Application of spatial structure. [0003] Umbrella-shaped roof structure is one of t...
