Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1. the device comprises wood wedges, 2 reinforcing steel bar weights, 3 supporting bracket bases, 4 supporting bracket supports, 5 supporting bracket beams, 6 supporting bracket sliding grooves, 7 sliding rollers, 8 triangular wood blocks, 9 limiting plates, 10 lifting rings, 11 hand chain blocks, 12 steel wire ropes, 13 tensioning jacks, 14 hollow plates to be tensioned.
Detailed Description
The invention is described in connection with the accompanying drawings and the embodiments:
as shown in fig. 1, a multidirectional moving apparatus of a prestressed tension jack has a support bracket base 3 provided on a hollow slab 14 to be tensioned; the supporting bracket base 3 is arranged at the top of one end of the hollow slab 14 to be tensioned; a supporting bracket support 4 which is vertical to the hollow slab to be tensioned is fixed on the supporting base 3; a support bracket beam 5 is fixed at the top of the support bracket strut 4; the supporting bracket beam 5 is made of I14I-shaped steel; one end of the support bracket beam 5 is fixed on the top of the support bracket strut 4, the other end is a cantilever end, and the cantilever end extends out of the hollow slab 14 to be tensioned on the same plane; the upper end surface of the supporting bracket beam 5 is provided with a supporting bracket sliding groove 6 for the sliding roller 7 to horizontally move; the support bracket chute 6 is made of No. 5 channel steel; the sliding roller 7 can horizontally move in the supporting bracket sliding groove 6; the sliding roller 7 is connected with a chain block 11 through a lifting ring 10; a steel wire rope 12 is wound on the chain block 11; two ends of the steel wire rope 12 are connected to the top of the tensioning jack, and the other end of the steel wire rope rounds the hand-operated block to form a handheld end.
A triangular wood block 8 for temporarily positioning the sliding roller is arranged corresponding to the sliding roller.
Limiting plates 9 are respectively arranged at two ends of the supporting bracket beam 5.
The working principle is as follows: firstly, a support bracket is hung to the end part of the top of a hollow slab to be tensioned by a 5t gantry crane in a hollow slab prefabrication plant, then an upper hook of a 2-ton chain block is connected with a lifting ring, a lower hook of the chain block, a steel wire rope and a chain are connected with a lifting point of a tensioning jack, 2 triangular wood blocks are placed on a roller sliding chute for temporarily fixing a sliding roller, after the oil return tensioning of the jack is finished, the chain is manually loosened downwards by 2cm in the vertical direction, and the jack is partially separated from a beam body. And then taking off the 2 temporarily limited triangular wood blocks, driving the roller by the hand chain to separate the jack from the working length part of the tensioned steel strand in the horizontal direction, and then rotating the support bracket strut to move to the next strand of steel strand to be tensioned.
