Description

A kind of curved space pipe truss installation method
Technical field
The present invention relates to a kind of truss installation method, and in particular to a kind of curved space pipe truss installation method.
Background technology
In recent years, space truss architecture because of it from heavy and light, span is big, short construction period, variation in moulding complexity U.S.A are refuted The features such as bank, is rapidly developed, and is used widely in the Big Space Public Architectures such as gymnasium, exhibition pipe, airport.
Run in early stage International airport administration building main-inlet employs curved space truss structure, by outer layer batter post, column And roofing truss collectively constitutes fan truss structure, single Pin roofing truss most weight is 2.8 tons, main-inlet truss overall length 60m, beam overall 57m, always weigh about 137 tons.Main-inlet truss Steel Structure makes at home, and each part is through preassembling passed examination Afterwards, transported by sea by container to erecting bed, building site assembling and lifting are carried out by an Indian Company, production unit provides installation Scheme is to instruct site operation.Each transport section of truss Steel Structure need to meet the built-in size sea-freight of container and require, but can not be complete Portion splits into single part delivery, to reduce steel construction Assembling workload.
Both ends hold-down support installation method known to roofing truss use can day and night difference variation be produced greatly because of Middle East Raw stress causes truss structure modification to destroy, and after the batter post lifting in truss Steel Structure and before roofing truss installation, batter post Stability be also a construction Difficulties.
The content of the invention
Goal of the invention：The present invention is directed to deficiency of the prior art, proposes a kind of curved space pipe truss installation method, has Have ground assembling roofing truss, the method for whole section of lifting, have construction it is succinct, conveniently, short time limit and construction quality easily ensure, save About heavy mechanical equipment, reduce operating expenses the advantages of.
