Embodiment Construction
[0038] refer to Figure 1 to Figure 5 , a temporary traction connector for steel strands, including a first clip 7 and a second clip 8 respectively clamped on the ends of the active traction steel strand 1 and the steel strand 3 to be installed, respectively sleeved on the first clamp The first connection anchor 4 and the second connection anchor 5 on the outside of the sheet 7 and the second clip 8 , and the screw rod 6 rigidly connecting the first connection anchor 4 and the second connection anchor 5 .
[0039] The first clamping piece 7 and the second clamping piece 8 are all tapered, and the central axis of the first clamping piece 7 and the central axis of the second clamping piece 8 are respectively opened for passing through the active traction steel strand 1 and the channel of the steel strand 3 to be installed; the channel inner wall of the first clip 7 and the channel inner wall of the second clip 8 are respectively engaged with the active traction steel strand 1 an...

The invention provides a steel strand temporary traction connector and an application method thereof. The steel strand temporary traction connector comprises a first clamping piece and a second clamping piece which are respectively clamped end parts of a driving traction steel strand and a steel strand to be mounted, a first connecting anchorage device and a second connecting anchorage device which are respectively sleeved to the outer sides of the first clamping piece and the second clamping piece, and a screw for rigidly connecting the first connecting anchorage device and the second connecting anchorage device. Both the first clamping piece and the second clamping piece are tapered; pore passages which are used for penetrating the driving traction steel strand and the steel strand to be mounted are respectively formed in the centre shaft positions of the first clamping piece and the second clamping piece; the inner side walls of the pore passages of the first clamping piece and the second clamping piece are respectively in occlusion connection with the driving traction steel strand and the steel strand to be mounted. The steel strand temporary traction connector solves the technical problems that the effect is low, the construction difficulty is high and the construction method does not meet code requirements during connection or mounting of traditional super-long steel strand prestressed tendons.
Description
technical field [0001] The invention relates to the technical field of connector structures, in particular to a steel strand temporary traction connector and a use method thereof. Background technique [0002] With the rapid development of construction technology, in recent years, the continuous side length of my country's prestressed concrete structures has increased from tens of meters in the past to more than hundreds of meters, and the prestressed steel strand bundles have also gradually increased. In addition, the number of longitudinal bending and bending angle also showed an increasing trend. The appearance of this change just makes the utensils of the original construction prestressed concrete structure become inapplicable. [0003] At present, the commonly used connectors in construction can only be used for permanent connection of steel strands, but their dimensions are too large, occupy too much internal space of components, and have complex structures, so they ca...
