FIG. 2 is a schematic structural view of the positioning reinforcing steel bar passing through the positioning channel steel when the sliding support moves back and forth in the structure shown in FIG. 1;
fig. 3 is a schematic view of the use state of the positioning jig of the utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
as shown in fig. 1, the slidable prefabricated T-beam rib steel bar positioning jig comprises two longitudinal positioning beams 1 arranged in parallel at intervals from front to back, a pad beam 2 arranged between the two longitudinal positioning beams 1 and in parallel with the two longitudinal positioning beams 1, the two longitudinal positioning beams and the pad beam are supported on the ground, one end of a plurality of transverse beams 4 arranged in parallel at intervals from left to right is welded and fixed on the outer wall of one longitudinal positioning beam 1, the top wall of each transverse beam close to one side of the longitudinal positioning beam 1 is welded and fixed with the bottom walls of two main upright columns 9 arranged in parallel at intervals from front to back, and a plurality of positioning channel steel 10 are fixed between the two main upright columns 9 in parallel at intervals from top to bottom;
the other end of each crossbeam 4 is fixed with foot stand 3 along vertical direction, each crossbeam on sliding connection have two pulleys 5, two pulleys 5 fix respectively in the front and back both ends of the diapire of a support horizontal pole 6 that sets up along the horizontal direction. The bottom of a support upright rod 8 arranged in the vertical direction is welded on the support cross rod 6, and an inclined support rod 7 is welded between the support upright rod 8 and the support cross rod 6, so that the overall stability of the slidable support is improved.
The upper ends of every three main upright columns close to the longitudinal positioning beam 1 are connected and fixed by adopting longitudinal beams 12, so that the integrity of the whole jig frame is improved.
The one end of the many positioning steel bars 11 that the interval set up about the horizontal direction is welded respectively on support pole setting 8 according to the interval of arranging of prefabricated T roof beam rib reinforcing bar, the other end one-to-one of many positioning steel bars 11 insert in the location channel-section steel 10 and with location channel-section steel 10 sliding connection, when guaranteeing the slidable support back-and-forth movement, positioning steel bar 11 can accurately insert in the location channel-section steel 10, guarantees that the location is accurate. When the horizontal reinforcing bar of beam rib installation construction, location channel-section steel 10 can support positioning steel 11, prevents that positioning steel 11 from taking place to warp under the weight of the horizontal reinforcing bar of beam rib, leads to the horizontal reinforcing bar of beam rib location inaccurate.
And whether the arrangement distance of the positioning channel steel 10 and the positioning reinforcing steel bar 11 meets the design requirements is checked by pushing and pulling the slidable support.
During actual construction, after the prefabricated T-beam steel bars are processed in a steel bar processing field, beam ribs and corrugated steel are installed in the following steps:
firstly, manually pushing a support upright rod 8 to enable a slidable support to slide to a main upright post 9, and enabling a positioning steel bar 11 to penetrate into a positioning channel steel 10 to be used for positioning a beam rib horizontal steel bar;
secondly, mounting the beam rib semi-finished product steel bars according to the serial numbers, firstly mounting the horseshoe stirrup A on the longitudinal positioning beam 1, then penetrating the longitudinal main reinforcement B into the horseshoe stirrup A, welding and fixing the longitudinal main reinforcement B with the horseshoe stirrup A, directly placing the horizontal reinforcement C on the positioning steel bar 11, and binding and fixing the horizontal reinforcement C with the horseshoe stirrup A without linear adjustment;
thirdly, penetrating the corrugated pipe D into the horseshoe stirrup A, then accurately positioning the corrugated pipe D by adopting a corrugated pipe positioning device, and fixing the corrugated pipe D on the horizontal rib C by using a U-shaped clamping steel bar;
fourthly, after the beam rib reinforcing steel bars and the corrugated pipes are installed, the support upright rods 8 are manually pulled to slide the slidable supports out of the beam rib reinforcing steel bars, so that the beam rib reinforcing steel bars fall off, the positioning reinforcing steel bars 11 are withdrawn from the positioning channel steel 10, and the lifting of the beam rib reinforcing steel bars is not influenced by the jig any more;
and fifthly, hoisting the prefabricated pedestal to the prefabricated pedestal by adopting the hoisting carrying pole, so that the steel bar is installed.
The above examples are only for illustrating the present invention, and the structure, materials, connection mode of the respective components may be changed, and all equivalent changes and modifications made on the basis of the technical idea of the present invention should not be excluded from the scope of the present invention.
