Description
Technical Field
The utility model belongs to the technical field of the bridge construction, a during steel pipe arch wire shape control that is arranged in steel pipe tied arch bridge is related to, carry out measuring support positioner to the pore position of arched bridge jib.
Background
The steel pipe tied arch has the advantages of high bearing capacity, light dead weight, good plasticity, good fatigue resistance and shock resistance and the like, and is widely applied to the construction of roads and railway bridges. The steel pipe tied arch bridge mainly comprises a steel pipe arch, a tie bar and a suspender, the arching shape of the steel pipe arch is the control key point in the installation construction process of the steel pipe arch, the plane position deviation of the suspender channel greatly affects the control of the arching shape of the steel pipe and the stress state of the finished bridge, and the center of the suspender channel needs to be accurately measured during construction. The center of the boom tunnel is usually measured by a total station, but the boom tunnel is communicated up and down, and an upper locking port of the boom tunnel cannot support a prism vertical rod of the total station, so that the accurate measurement of the center position of the boom tunnel is difficult.
Disclosure of Invention
The utility model aims at providing a location strutting arrangement suitable for steel pipe tie rod encircles jib pore position measurement solves the problem that current steel pipe tie rod encircles jib pore position measurement location difficulty.
The technical scheme of the utility model as follows:
a support positioner that is used for steel pipe tied arch jib pore to measure which characterized in that: comprises a circular supporting plate with a diameter larger than the diameter of a suspender pore passage, a cross central line is carved in the middle of the top surface of the supporting plate, 4 sliding grooves penetrating through the supporting plate are arranged along the extension line of the cross central line, one side of each sliding groove is provided with length scales on the top surface of the supporting plate, a positioning device capable of sliding along the sliding groove is arranged in each sliding groove, each positioning device comprises a sliding plate and a positioning rod, the sliding plate is positioned on the top surface of the supporting plate, the upper end of the positioning rod passes through the sliding groove from the lower part of the supporting plate to be fixedly connected with the sliding plate, the lower end of the positioning rod extends to a certain length below the supporting plate, a limiting rod for limiting the positioning rod to move up and down is arranged on the bottom surface of the supporting plate along the direction vertical to the sliding groove, one side of the sliding plate, which is located on the sliding groove and provided with the length scales, is provided with a pointer facing the length scales, and the other side of the sliding plate, which is located on the sliding groove, is provided with a positioning bolt which penetrates through the sliding plate up and down.
The utility model discloses fore shaft central point on can the accurate positioning jib pore to for jib pore location provides effectual location holding surface with the prism pole setting, guarantee for the precision measurement is provided, and improved measurement work efficiency.

Detailed Description
As shown in figures 1, 2 and 3, the utility model comprises a circular support plate 1 with a diameter larger than the diameter of a suspender pore passage, a cross central line 2 is carved in the middle of the top surface of the support plate 1, 4 sliding grooves 3 penetrating through the support plate are arranged along the extension line of the cross central line, one side of each sliding groove is provided with length scales 4 on the top surface of the support plate, a positioning device 5 capable of sliding along the sliding groove is arranged in each sliding groove, each positioning device 5 comprises a sliding plate 51 and a positioning rod 52, the sliding plate 51 is arranged on the top surface of the support plate 1, the upper end of the positioning rod 52 passes through the sliding groove 3 from the lower part of the support plate 1 to be fixedly connected with the sliding plate 51, the lower end of the positioning rod 52 extends to a certain length below the support plate, a limiting rod 53 for limiting the up-and-down movement of the positioning rod is arranged on the bottom surface of the support plate 1 along the direction vertical to, and a positioning bolt 55 which penetrates through the sliding plate up and down is arranged on the other side of the sliding plate, which is positioned on the sliding groove.
In the specific implementation of the utility model, the ear plate 6 is arranged on the edge of the support plate for the convenience of carrying.
As shown in fig. 4, the utility model discloses during the use, support 1 bottom surface of backup pad at the davit pore way on the 7 tops of fore shaft, along 4 positioner 5 of spout slip, make 4 positioner's the length scale of pointer instruction unanimous, and 4 positioner's locating lever 52 all pastes the outer wall of fore shaft 7 on the tight jib pore way, the intersect of backup pad cross central line this moment, the center coincidence of fore shaft on the center of backup pad 1 and the jib pore way promptly. The positioning bolts 55 on each sliding plate 51 are tightened to fix 4 positioning devices on the supporting plate, so that the supporting plate 1 is fixed at the top of the locking notch 7 on the lifting rod hole way, and then a measurer can erect the prism vertical rod 8 on the center of the supporting panel 1 to start measurement.
