The utility model has the beneficial effects that the anchor body and the connecting hole on the anchor body can effectively form an anchor structure for fixing the steel strand after the prestress is applied, the detection of the prestress of the steel strand can be effectively realized by arranging the anchor body into the detection seat and the base, and when the prestress is detected to be smaller than the threshold value, a signal is sent to the outside.
Drawings
Fig. 1 is a schematic structural view of a steel strand prestressed anchorage structure according to the present utility model.
Detailed Description
The utility model will be further described in detail with reference to examples of embodiments shown in the drawings.
Referring to fig. 1, a steel strand prestress anchorage structure of the present embodiment includes a cylindrical anchorage body 1, a plurality of connection holes for the steel strand to penetrate are formed on the end of the anchorage body 1, the anchorage body 1 includes a base 12 and a detection seat 13, the detection seat 13 is coaxial on one end of the base 12, the connection holes penetrate through the detection seat 13 and the base 12, an end surface of the detection seat 13 facing away from the base 12 is a pressure detection end surface, so as to detect the pressure applied to the end surface, and when the applied pressure is smaller than a preset threshold, a signal is sent to the outside, when the steel strand prestress is anchored, a bolt for fixing the steel strand is abutted against the pressure detection end surface, and the corresponding pressure is applied on the pressure detection end surface according to the prestress applied to the steel strand, thereby realizing the prestress detection of the steel strand in a mode of detecting the pressure applied to the end surface, and then prompting whether the prestress of the steel strand is enough for an external worker in a mode of sending the signal.
As an improved specific embodiment, the detection seat 13 is provided with a detection groove 14 towards one end of the base 12, the end surface of the base 12 is fixed with a pressure sensor 15, the pressure sensor 15 is provided with a detection rod, the upper end of the detection rod is fixedly connected with the position of the center of the bottom of the detection groove 14 so as to detect the pressure born by the bottom of the detection groove 14, and the pressure born by the end surface can be effectively detected through the arrangement of the pressure sensor 15, so that the detection of the end surface pressure is simply and effectively realized.
