Description
Technical Field
The utility model belongs to a single stretch-draw support frame of suspension cable steel strand wires.
Background
The stay cable tensioning is a key process of cable-stayed bridge construction, and in the tensioning process, a bundle of stay cable steel strands needs to be tensioned singly, and the single anchoring is carried out after the tensioning is finished. However, each bundle of stay cable is composed of dozens of steel strands, so that the stay cable is influenced by the previous position in the process of tensioning the next steel strand, the jack is inconvenient to fix and exert force, great inconvenience is brought to the construction process, the construction time is prolonged, and the working efficiency is influenced.
Disclosure of Invention
The utility model aims at designing a single stretch-draw support frame of suspension cable steel strand wires, can avoid the influence each other between the tension in-process steel strand wires, improved the stretch-draw precision of steel strand wires, reduce the work load of follow-up accent cable, reduced personnel and mechanical consumption. The support structure has the advantages of simple structure, firm support, convenience in disassembly and assembly, time and labor conservation, flexibility in operation and high construction efficiency.
Therefore, the utility model discloses an opening pull ring, opening pull ring and solid fixed ring are upper and lower spacing distance setting, are connected through the pole setting under the opening pull ring between terminal surface and the solid fixed ring up end, pole setting bottom and solid fixed ring up end rigid coupling, and the pole setting top is passed opening pull ring and is passed the bolt-up on the opening pull ring up end, and solid fixed ring both sides are equipped with the connecting plate, are equipped with the perforation on the connecting plate, and fastening bolt passes the perforation and can fix the connecting plate of solid fixed ring both sides on the suspension cable tip. The tensioning ring and the fixing ring are both in a hollow circular ring shape, the aperture of the tensioning ring is 40 cm-80 cm, and the aperture of the fixing ring is 50 cm-90 cm. The opening pull ring and the fixing ring are arranged in parallel. The opening pull ring and the fixing ring are made of stainless steel materials. The number of the vertical rods is 2-4. The top of the upright rod is provided with a threaded part. Above-mentioned structural design has reached the utility model discloses a purpose.
The utility model discloses can avoid the influence each other between the stretch-draw in-process steel strand wires, improve the stretch-draw precision of steel strand wires, reduce the work load of follow-up accent cable, reduce personnel and mechanical consumption. The support structure has the advantages of simple structure, firm support, convenience in disassembly and assembly, time and labor conservation, flexibility in operation, stable performance and high construction efficiency.

Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, a single stay cable steel strand tensioning support frame, including opening pull ring 1, opening pull ring and solid fixed ring 6 are upper and lower spacing distance setting, be connected through pole setting 3 between terminal surface and the solid fixed ring up end under the tension ring, pole setting bottom and the solid fixed ring up end rigid coupling, the pole setting top is passed opening pull ring and is fastened on the tension ring up end through bolt 2, gu the fixed ring both sides are equipped with connecting plate 5, be equipped with the perforation on the connecting plate, fastening bolt 4 passes the perforation can fix the connecting plate of solid fixed ring both sides on the stay cable tip. The vertical rods can be used for evacuating the steel strands during tensioning.
The tensioning ring and the fixing ring are both in a hollow circular ring shape, the aperture of the tensioning ring is 40 cm-80 cm, and the aperture of the fixing ring is 50 cm-90 cm. The opening pull ring and the fixing ring are arranged in parallel. The opening pull ring and the fixing ring are made of stainless steel materials. The number of the vertical rods is 2-4. The top of the upright rod is provided with a threaded part. The top of the vertical rod can be conveniently fastened on the upper end surface of the tensioning ring by the threaded part through bolts.
When the stay cable is used, the fixing ring is sleeved and fixed on the end part of the stay cable through the connecting plates and the locking bolts on the two sides, and the stay cable steel strand bundle penetrates through the tension ring; when single steel strand is tensioned, the steel strands are tensioned and anchored one by one from inside to outside according to a tensioning sequence, the tensioning ring can be used as a supporting point of a jack in the tensioning process, the vertical rod can be used for evacuating the steel strands in the tensioning process, mutual influence among the steel strand in the tensioning process is avoided, and the tensioning precision of the steel strand is improved.
In a word, the utility model discloses can avoid the influence each other between the stretch-draw in-process steel strand wires, improve the stretch-draw precision of steel strand wires, reduce the work load of follow-up accent cable, reduce personnel and mechanical consumption. The support structure has the advantages of simple structure, firm support, convenience in disassembly and assembly, time and labor conservation, flexibility in operation, stable performance and high construction efficiency. Can be popularized and used.
