Embodiment Construction
[0032] The present invention will be further described below in conjunction with the accompanying drawings.
[0033] like figure 1 , figure 2 As shown, an in-situ tensioning system for beams and slabs reinforced with integrated prestressed fiberboards includes tension end anchors 1 and fixed end anchors 10 respectively anchored on beams or slabs, and is connected with tension end anchors 1 The convex hydraulic jack 3 also includes a two-part clamp 4, a cylinder 6 with a column cap 5 is welded to the upper surface of the clamp 4, and a sleeve 7 nested outside the cylinder 6 is connected by a push rod 8 On the convex hydraulic jack 3; one end of the fiberboard 9 is clamped by the clip-type clamp 4 at the tension end, and the other end is anchored to the anchor 10 at the fixed end. The tension end anchor 1 is composed of an anchor cup and a clip, and there are two sets of threaded holes on the anchor cup, one set of holes is used for planting bars to anchor on the beam, and th...
