Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the utility model provides a device that is used for external prestressing steel strand wires of H shaped steel component to fix a position and reset includes: two unilateral fastener 1, a screw rod 2 and two nuts 3 and a plurality of revolving fragments 4 that match with screw rod 2 in addition, still include two gaskets 5.
Referring to fig. 2 and 3, the one-side card member 1 includes: an upper card board 11, a lower card board 12, a side baffle 13 and a stiffening plate 15. Go up cardboard 11 and cardboard 12 parallel from top to bottom down to all be fixed in the homonymy of side shield 13, go up the flange that the distance between cardboard 11 and the cardboard 12 down can just block external prestressing force reinforcing H shaped steel roof beam 7. The side baffle 13 is provided with a long round hole 14 for the screw rod 2 to pass through, and the long round hole 14 extends along the vertical direction, so that the screw rod 2 can move up and down according to the height of the steel strand 6, and the rotating piece 4 can clamp the steel strand 6 firmly. The stiffening plate 15 is in the shape of a right triangle, and two right-angle sides are respectively and fixedly connected with the bottom surface of the lower clamping plate 12 and the side surface of the side baffle 13.
Referring to fig. 5 and 6, the rotating plate 4 may be either circular or hexagonal, threaded at the axial center, and matched with the threads of the screw 2.
Referring to fig. 4, the spacer 5 is square, and a circular hole is formed in the center of the spacer, and the diameter of the circular hole needs to be slightly larger than the outer diameter of the screw rod 2 to ensure that the spacer 5 can be smoothly sleeved at both ends of the screw rod 2, and the spacer 5 is used for being cushioned between the side baffle 13 and the nut 3.
Referring to fig. 1, the utility model provides a device that is used for external prestressing steel strand positioning of H shaped steel component and resets, its method of use as follows:
with unilateral fastener 1 with the beam flange card of external prestressing force reinforcement H shaped steel roof beam 7 between last cardboard 11 and lower cardboard 12, the both sides of beam flange each side respectively sets up a unilateral fastener 1, then link up two unilateral fasteners 1 with screw rod 2, meanwhile, overlap a plurality of revolving fragment 4 on screw rod 2 and through the both sides of rotatory every steel strand wires 6 of being fixed in, later 5 and nut 3 are sheathe in proper order at the both ends of screw rod 2, screw up nut 3 at last, so, the relative external prestressing force reinforcement H shaped steel roof beam 7's of steel strand wires position just can not take place to shift because of the stretch-draw. For the steel strand 6 which is tensioned, if the position of the steel strand 6 relative to the external prestress reinforced H-shaped steel beam 7 changes, the relative position of the steel strand 6 and the external prestress reinforced H-shaped steel beam 7 can be adjusted by rotating the rotating piece 4 and the screw cap 3 of the device, so that the relative position of the steel strand 6 and the external prestress reinforced H-shaped steel beam 7 does not change any more, and the structure stability is facilitated.
