Slidable construction stable annular beam

Abstract

The invention relates to a slidable construction stable annular beam applied in the process of high-rise and super high-rise framework core tube construction and belongs to the technical of structural projects. The slidable construction stable annular beam is composed of steel annular beams and fastening pieces. The steel annular beams are horizontally placed between adjacent framework columns, and the two ends of the steel annular beams are connected with the annular fastening pieces. The annular fastening pieces can be arranged on the peripheries of the framework columns in a sleeving mode and fixedly connected with the framework columns. The construction stable annular beam can slide in the height direction of a framework core tube structure system through the mode of locking and opening the fastening pieces. The slidable construction stable annular beam is constructed by full steel, the self weight is light, and site assembling and mounting are convenient and fast. The slidable construction stable annular beam only needs to be mounted at a time in the construction process of the same project. The stabilizing problem of the cantilever framework columns in the process of each construction step is solved through vertical sliding, and multiple times of disassembling and assembling are not needed. Disassembling, recycling and circular using are easy, therefore, the cost can be saved to the maximum extent, the construction period can be shortened to the maximum extent, and meanwhile the environment influence of the slidable construction stable annular beam is reduced to the maximum extent.

Description

technical field [0001] The invention relates to a slidable construction-stabilizing ring beam used in the construction process of high-rise and super-high-rise frame core tubes, and belongs to the technical field of structural engineering. Background technique [0002] With the continuous development of social economy, a large number of high-rise and super high-rise building structures have been built at home and abroad, among which the frame core tube structure system is one of the most commonly used building structure systems. The frame core tube structure system is composed of the core tube in the middle and the external frame system. The core tube is relatively rigid and generally bears more than 80% of the horizontal shear force of the building system. The core tube and the peripheral frame system are connected by horizontal outrigger trusses arranged at a certain height to ensure the coordinated force of the inner tube and the outer frame; the peripheral frame system i...

Problems solved by technology

This method has the following problems: (1) The construction of cross bracing between columns is cumbersome and costly; (2) As a temporary support component, cross bracing needs to be dismantled after the construction in this area is completed, which increases the cost and at the same time impact on the construction period
