Abstract

The utility model discloses a connector, which belongs to the technical field of connectors connecting longitudinally prestressed steel bar ends of longitudinally connected track slabs; There are reverse threads, and the cross-section of the rectangular parallelepiped is a regular hexagon; the utility model is convenient and quick to install, and makes the connection between the prestressed steel bars of the longitudinally connected track slabs more reliable. The utility model is especially suitable for ballastless track longitudinal Even track slab laying.

Description

Connector

technical field

The utility model relates to a connector, in particular to a connector for connecting the ends of longitudinal prestressed steel rods of longitudinally connected track slabs.

Background technique

The currently used longitudinal track slabs are connected by connecting steel plates and connecting bolts, that is, the threaded steel bars at the gaps in the longitudinal end faces of two adjacent longitudinal track slabs are respectively passed through the holes on the connecting steel plates and fixed by nuts. , the connecting bolts are passed through the connecting holes of the connecting steel plates, and the connecting steel plates are fixed by supporting nuts, and at the same time, the longitudinal centerlines of the two adjacent vertically connected track plates meet the requirements of track laying. The connecting device has complicated procedures, low installation efficiency and unreliability.

Utility model content

The purpose of the utility model is to provide a connector which is convenient and quick to install and makes the connection between the prestressed steel bars of the longitudinally connected track slab more reliable.

The technical solution of the utility model is: a connector, including a long hexagonal body with an internally threaded hole, one end of the internally threaded hole is provided with a right-handed thread, and the other end is provided with a left-handed thread, and the long hexagonal The cross-section of the body is a regular hexagon. Left-handed and right-handed thread settings facilitate the simultaneous screwing in and out of the connected prestressed steel rods.

The beneficial effect of the utility model is that the installation is convenient and quick, and the connection between the prestressed steel rods of the longitudinally connected track slabs is more reliable, and a prestressed system is established between two adjacent track slabs through the prestressed steel rods.

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
