Problems solved by technology
[0003]The steel strands in the existing prestressed anchors for highway bridge construction are generally fixed with clips or pressure plates and anchor plates. It will be more cumbersome, in order to gather the steel strands together, it needs to pass through a through hole, often it will be more difficult to install the last few steel strands

The embodiment of the invention discloses a pre-stressed anchorage device for highway bridge construction, relates to the technical field of pre-stressed anchorage devices, and mainly aims to solve the problem that a steel strand of an existing pre-stressed anchorage device for highway bridge construction is inconvenient to mount. The anchorage device comprises a stranded wire and a first spring which sleeves the stranded wire; the device further comprises a threading assembly, a first extrusion assembly and a second extrusion assembly, a plurality of steel strands can penetrate through the first threading part at the same time, the first extrusion assembly and the second extrusion assembly are preassembled in the first threading part and the second threading part, and a driving part in the second extrusion assembly drives a second extrusion part to move so that the steel strands can be rapidly fixed; and meanwhile, the multiple steel strands located in the first threading part can be clamped and fixed through cooperative use of an elastic part in the first extrusion assembly, the second extrusion part and an insertion part located on the second threading part. Thus, thepre-stressed anchorage device is characterized by convenient installation.
Description
technical field [0001] The application relates to the technical field of prestressed anchors, in particular to a prestressed anchor for highway bridge construction. Background technique [0002] Prestressed anchors are suitable for concrete prestressed tensioning anchors in the process of engineering construction. Generally, they are often used in large-span and super-long industrial and civil buildings and bridge construction. They are pre-installed and positioned, and then concrete is poured and buried. The two ends of the concrete, that is, the two ends of the bellows, make the jack more stable when stretched. [0003] The steel strands in the existing prestressed anchors for highway bridge construction are generally fixed with clips or pressure plates and anchor plates. This method will be cumbersome when installing the steel strands. In order to gather the steel strands together, It needs to be passed through a through hole, and it is often difficult to install the las...
