Abstract
The utility model relates to a connector for multiple steel strands for road and bridge prestressing. In the prior art, steel strands are connected and fixed usually in the mode that the steel strands at the two ends are connected through a connecting cylinder and two steel working clamping piece sets in the connecting cylinder, the connection mode is suitable for the connection of a single-hole anchorage device with a single steel strand, but multiple connectors are needed when multiple steel strands are connected at the same time, therefore, cost is increased, and work efficiency is lowered. The connector for the multiple steel strands for road and bridge prestressing comprises a corrugated pipe A (1), wherein the corrugated pipe A is connected with an anchor bearing plate (2), the anchor bearing plate is connected with a connector body (3), working clamping pieces (4) are installed on the connector body, the connector body is installed inside a protection cover (5), the protection cover is connected with a corrugated pipe B (7) through a constraint ring (6), a right end steel strand (8) penetrates through the connector body and is installed on an extrusion anchor (9), and the extrusion anchor is connected with the connector body. The connector is used for connecting the multiple steel strands.
Description
Technical field:
The utility model relates to a kind of bridge prestressing force with many steel hinge line connectors.
Background technology:
In the road and bridge construction member, except adopting reinforcing bar, adopt in a large number steel strand, its main cause is because steel strand intensity is large, easily anchoring etc., but in the connection of steel strand, still lack particularly large-tonnage wire rope connector of the coupling that is connected firmly.
For fixing of prestress wire, two kinds of pre-tensioning system and post stretching are arranged, the key of prestressing technique is anchor rod, anchor rod is to guarantee one of key that prestressed reinforced concrete construction is safe and reliable, the stressed of ground tackle wanted evenly, being connected and fixed of the steel strand of prior art, generally by connecting cylinder and the connection of interior two groups of steel work clip sheets realization two ends steel strand of be connected, be applicable to single hole anchor device and be connected connection with single steel strand, when connecting simultaneously for many, need to adopt many group connectors, increase cost, reduce operating efficiency.
Summary of the invention:
The purpose of this utility model provides a kind of bridge prestressing force with many steel hinge line connectors.
Above-mentioned purpose realizes by following technical scheme:
A kind of bridge prestressing force is with many steel hinge line connectors; its composition comprises: bellows A; described bellows A is connected with anchor plate; described anchor plate is connected with connector; work clip sheet is installed on the described connector, and described connector is installed in the protective cover, and described protective cover is connected with bellows B by the constraint circle; the right-hand member steel strand pass described connector and are installed on the extruding anchor, and described extruding anchor is connected with described connector.
Described bridge prestressing force is equipped with the left end steel strand with many steel hinge line connectors on the described work clip sheet, described left end steel hinge line passes described bellows A by spiral bar, described connector, described anchor plate.
Described bridge prestressing force is equipped with stack with many steel hinge line connectors on the described protective cover.
Beneficial effect:
The utility model compact conformation, easy to connect, firm, can connect simultaneously many group steel strand.
The utility model can provide firmly as the large-tonnage wire rope connector and connect.
Single product of the present utility model has substituted many groups connector, has reduced construction cost, has improved operating efficiency.
