Description
Technical field
Spelled the present invention relates to a kind of steel structural roof truss slip control method, more particularly to long-span roofing truss high-altitude
Dress slip control method.
Background technology
Slide installation method has the time of decades the seventies from twentieth century so far, passes through till now from proposition is started
Several stages, technology gradually tends to ripe, corresponding to occur greatly to design requirement more and more higher along with the development of construction market
Span structure with meet the aesthetics of architecture and using function demand, can effectively save space, can carry out three-dimensional operation, install imitate
Rate is high, degree of safety is high.
But longspan structure installation process for synchronism and amount of deflection control it is particularly important, be related to installation process with
And the safety problem of later stage structure, by prolonged development, synchronous sensing computer controls mould has been applied in the prior art
Block, will be controlled in slipping to synchronism, and this automatic control system has its advantage, but in operation due to
Manual operation is improper, or system goes wrong be easy to extremely cause cumulative errors generation relatively large deviation in slipping in itself,
Less it is conveniently adjusted, and system cannot detect that simultaneity factor is in itself to the amount of deflection error in truss slipping in itself
Complicated, cost is high, does not reach the requirement of live conduct monitoring at all levels.
Long-span roofing truss installation at high altitude sliding control urgently proposes a kind of new method, to solve cost and improve to slide
