Description

Technical Field

[0001] The utility model relates to the technical field of hoisting tools, in particular to a corrugated pipe positioning device. Background Technique

[0002] The prestressed system of a prestressed bridge is the core content of the structure bearing, and its construction quality is of utmost importance during the construction process of the prestressed structure. The precise positioning of the vertical coordinates of the corrugated pipe in the cast-in-place prestressed box girder of the bridge is the primary link in the on-site quality control. The conventional process is that after the longitudinal and transverse beam steel skeletons are formed, the cross support positioning steel bars are spot-welded on the vertical distribution steel bars at a certain interval. The corrugated pipe is placed on the positioning steel bars and longitudinally connected firmly, and then the "U"-shaped buckle bars are added and spot-welded for reinforcement, and then the steel strand is threaded.

[0003] The Chinese utility model patent with the patent publication number CN218970694U, which was publicly disclosed on December 2, 2022, discloses an assembled precast beam corrugated pipe coordinate positioning tooling. The first azimuth coordinate of the pipe positioning frame is determined by using the positioning base, the fixed vertical rod and the movable vertical rod. The second azimuth coordinate of the pipe positioning frame is adjusted and determined by using the inner bolt and the outer bolt. The third azimuth coordinate of the pipe positioning frame is adjusted and determined by using the adjusting screw rod, so as to realize the group center coordinate positioning of the pipe positioning frame. The use and operation are simple, and the control and adjustment are convenient. However, its control frame cannot be adjusted according to the corrugated pipe diameter, resulting in difficulty in positioning the corrugated pipe. Content of the Utility Model

[0020] As Figures 1-3As shown in the figure, the corrugated pipe positioning device of this embodiment includes an insertion plate 1, a docking plate 2 and a fixing rod 9. The insertion plate 1 and the docking plate 2 are arranged on both sides of the corrugated pipe. Both ends of the fixing rod 9 are fixed to the insertion plate 1 and the docking plate 2 respectively. First adjustment plates 3 are sleeved at the endpoints of the insertion plate 1; second adjustment plates 4 are sleeved at the endpoints of the docking plate 2. One end of the fixing rod 9 is fixed to the first adjustment plate 3, a limiting block 14 is fixed at the other end of the fixing rod 9, and a docking block 15 matching the limiting block 14 is fixed at the endpoint of the second adjustment plate 4; when fixing the corrugated pipe, a wing nut 12 passes through the limiting block 14 and the docking block 15 and is threadedly connected to a nut 13.

[0021] After adjusting the length and width of the insertion plate 1 and the first adjustment plate 3 according to the diameter of the corrugated pipe and the steel bar skeletons on both sides, pass the fixing rods 9 and the extension rods 10 at the four corners through the rectangular slots of the steel bar skeletons on both sides, and the corrugated pipe can be clamped in the middle. Make the docking plate 2 and the second adjustment plate 4 fit against the surface of the steel bar skeleton on the other side, and at the same time adjust to the corresponding length and width, so that the docking block 15 corresponds to the limiting block 14, screw the wing nut 12 into the middle of the limiting block 14 and the docking block 15, and then lock the wing nut 12 with the nut 13 to complete the positioning of one corrugated pipe. It can be installed at the corresponding cut-off point according to the on-site corrugated pipe, so that the corrugated pipe is positioned to maintain stability.

[0022] Further, a threaded pipe 11 is threadedly connected inside the fixing rod 9. The outer end of the threaded pipe 11 is rotatably connected to one end of the extension rod 10, and the other end of the extension rod 10 is fixed to the limiting block 14.
