The stiff skeleton of adjacent segment is interconnected by a pair flange bolt, and bolt through described flange, and is fixed with lock nut and regulating nut respectively at the opposite side of flange and phase dorsal part.
Described fixed mechanism comprises " door " cabinet frame formed with shaped steel welding, described " door " cabinet frame partly encloses in cable saddle, and Open Side Down, " door " cabinet frame vertical direction and cable saddle closely connected, horizontal direction and cable saddle lateral surface leave and regulate gap, and horizontal direction is provided with adjusting bolt.
The described adjusting device for adjusting cable saddle three-dimensional coordinate comprises regulating nut between adjacent two joint stiff skeleton flange dishes and lock nut and cable saddle " door " cabinet frame place adjusting bolt.
A kind of cable saddle Fast Installation, localization method, it comprises the following steps:
(1) prefabricated stiff skeleton, stiff skeleton adopts shaped steel as its vertical rod, adopts channel-section steel (or being other shaped steel) as connecting support and diagonal brace, each making one joint between vertical rod, often restraining is done highly to determine according to king-post merogenesis height, and often joint is the guiding of next joint;
(2) the prefabricated stiff skeleton completed goes to cable saddle installed base, measure according to cable saddle and this joint stiff skeleton relative position, on stiff skeleton, saddle's position welding supports, cable saddle is installed, stiff skeleton fixes cable saddle with shaped steel welding " door " cabinet frame, " door " cabinet frame vertical direction and cable saddle closely connected, horizontal direction and cable saddle lateral surface leave and regulate gap, horizontal direction is provided with adjusting bolt, stiff skeleton internode and and cable saddle installed base between connecting portion welding flange, stiff skeleton internode is interconnected by flange bolt, bolt is arranged regulating nut and lock nut,
(3) the prefabricated stiff skeleton that completes and cable saddle by boom hoisting integral hoisting to king-post, be interconnected by flange bolt with the stiff skeleton of having constructed in king-post, survey crew measures the three-dimensional coordinate of cable saddle, adjusting the three-dimensional coordinate of cable saddle until meet design requirement by adjusting regulating nut between two joint stiff skeleton flange dishes, lock nut and cable saddle " door " cabinet frame place adjusting bolt, being finally welded and fixed cable saddle and skeleton.
Described stiff skeleton precast pedestal is made up of relatively two measure-alike fixed end moulds, and described fixed end mould is provided with the structure can fixing described stiff skeleton vertical rod, and stiff skeleton vertical rod cross binding is between described fixed end mould.
The feature that the present invention has changes engineering stiff skeleton to be in the past separated the construction technology of installation with cable saddle, by integral prefabricated cable saddle and stiff skeleton, realizes cable saddle and stiff skeleton once mounting puts in place, accurate positioning, adjust easy, handling safety, construction effect is remarkable.
