Preferably, the connected mode of described split bolt and split bolt sealing piece is for being welded to connect.
A compound split bolt method for arranging for fixing prestressing tendon, is characterized in that, comprise following methods step:
(1) plane coordinate system is set in prestressed girder side, is set to X-axis along prestressed girder span direction, is set to Y-axis along prestressed girder short transverse;
(2) according to the diameter of the design section size of prestressed girder, scaffolding height, template and support system material type selecting parameter determination split bolt, arrangement pitch and layout quantity, obtain the position coordinates of split bolt on prestressed girder lateral plane coordinate system, and in this plane coordinate system, mark split bolt layout node;
(3) according to design and the code requirement of prestressing tendon, determine the installation site of prestressing tendon in prestressed girder, obtain the position coordinates in the plane coordinate system that prestressing tendon arranges in prestressed girder side further;
(4) in this plane coordinate system, the position coordinates of prestressing tendon and the position coordinates of split bolt are compared, the position coordinates of the split bolt closed on by the position coordinates with prestressing tendon is temporary fixed is compound split bolt;
(5) position coordinates in the plane coordinate system arranged in prestressed girder side with prestressing tendon is for benchmark, regulate the position coordinates of the compound split bolt closed on this position coordinates, the position coordinates of the compound split bolt after adjustment and the prestressing tendon position coordinates in plane coordinate system with overlap.
The present invention's beneficial effect is compared with prior art:
(1) this compound split bolt is applicable to large span, high heavy in section prestressed girder work progress is fixed prestressing tendon, primarily of Screw arbor with nut at both-ends and prestressing tendon clip composition, this prestressing tendon clip is U-shaped clip, the internal diameter of U-shaped clip is greater than the diameter of prestressing tendon, Screw arbor with nut at both-ends top is welded in by spot welding mode, whole component adopts the prefabricated processing of batch production, split bolt and prestressing force clip are united two into one, can not only good fixed form support, and presstressed reinforcing steel and split bolt fixed form operation in saving work progress, save a large amount of manpowers, material resources and financial resources,
(2) this compound split bolt method for arranging, in prestressed girder side, plane coordinate system is set, confirm compound split bolt and prestressing tendon position coordinates in the coordinate system in work progress respectively, with the position coordinates of prestressing tendon for benchmark, in the coordinate system the compound split bolt closed on is adjusted to the position coincided with the position coordinates of prestressing tendon, and other node location is set to conventional split bolt in the coordinate system, conventional split bolt can be set up as required when compound split bolt adjustment spacing is excessive, ensure the reliability that in work progress, prestressing tendon and prestressed girder are fixed.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
Embodiment 1, see Fig. 1, a kind of compound split bolt of fixing prestressing tendon, this split bolt is primarily of Screw arbor with nut at both-ends and prestressing tendon clip composition, Screw arbor with nut at both-ends is connected by spot welding mode with prestressing tendon clip, prestressing tendon clip has 2, prestressing tendon clip is U-shaped clip, the internal diameter of U-shaped clip is greater than the diameter of prestressing tendon, be convenient to prestressing tendon pass and fix this U-shaped clip, U-shaped clip employing model is the reinforcing bar of HPB235 Φ 6, and the Template Location card be provided with between U-shaped clip and the screw thread of Screw arbor with nut at both-ends Template Location, whole component adopts the prefabricated processing of batch production, split bolt and prestressing force clip are united two into one, can not only good fixed form support, and presstressed reinforcing steel and split bolt fixed form operation in saving work progress, save a large amount of manpowers, material resources and financial resources.
