Problems solved by technology

[0002] The traditional tensioning system is mainly controlled by a notebook, but the specific tensioning is done outdoors, and the controllability is poor under outdoor working conditions. It only relies on the notebook for control. Once the notebook computer system fails, it will It will cause serious accidents to the entire construction, and at the same time cause relatively large economic losses.

Embodiment 1

[0012] A tensioning system according to the present invention, the system fixes the working anchor 4, the jack 2, the limit plate 3 and the tool anchor 1 on one end face of the prefabricated beam 6 in sequence, and the steel strands pass through the prefabricated beam 6 in sequence , work anchor 4, limit plate 3, jack 2 and tool anchor 1, and they are all in close contact with each other, wherein the control host 5 is connected to the jack 2, and when tensioned, the steel strand on the other side of the prefabricated beam 6 The wire is fixed, and then the control device is started, and the control device controls the action of the jack 2. The jack 2 continuously tightens the steel strand, and the tool anchor 1 automatically locks the steel strand. Since the position of the jack 2 is fixed, the steel strand During the tensioning process, the jack 2 tightens the limiting plate 3, and the limiting plate 3 tightens the clip inside the working anchor 4. The limiting plate 3 can effe...

Embodiment 2

[0014] This embodiment is basically the same as Embodiment 1, the difference is that the jack 2, the limit plate 3, the working anchor 4 and the tool anchor 1 described in this embodiment are two groups, which are respectively arranged at the two ends of the prefabricated beam 6. The jacks 2 described above are all connected to the same control host 5, and the tensioning action can be controlled by the same control host 5.

Embodiment 3

[0016] This embodiment is basically the same as Embodiment 1 or 2, except that the control host 5 described in this embodiment is also provided with a remote control device connected thereto. The remote controller can control the work of the remote control host, and when the operating conditions are harsh, the remote control can be used to control the tensioning work. In this embodiment, it is more preferable to set the remote control device as a box-type remote control.

Abstract

The invention discloses a tensioning system, and relates to a tensioning system applied to a bridge for building construction. The tensioning system comprises a tool anchor, a jack, a limiting plate and a working anchor which are connected in sequence, and a control main unit, wherein the control main unit is connected with the jack. The tensioning system can independently control the whole tensioning process by using a control device, and is high in reliability and safely and conveniently operated.

Description

【Technical field】 [0001] The invention relates to a tensioning system applied to prefabricated beams for building construction. 【Background technique】 [0002] The traditional tensioning system is mainly controlled by a notebook, but the specific tensioning is done outdoors, and the controllability is poor under outdoor working conditions. It only relies on the notebook for control. Once the notebook computer system fails, it will It will cause serious accidents to the entire construction, and also cause relatively large economic losses. 【Content of invention】 [0003] The invention proposes a tensioning system which can independently control the tensioning work. [0004] A tensioning system according to the present invention includes a tool anchor, a jack, a limit plate, and a working anchor arranged in sequence, and the system also includes a control host connected to the jack. [0005] More preferably, there are multiple sets of jacks, limit plates, work anchors and t...
