Embodiment 1

[0037] like Figure 1-2 As shown, a straddle type monorail continuous steel structure PC track beam adjustment device according to the present invention includes:

[0038] pier 1;

[0039] A steel pipe spherical hinge support 3, which is fixedly arranged on the top of the pier 1;

[0040] A pre-embedded support block 21, the pre-embedded support block 21 is arranged at the end of the PC track beam 2, and the pre-embedded support block 21 is integrally formed with the PC track beam 2, the bottom of the pre-embedded support block 21 It is fixedly connected with the top of the steel pipe spherical hinge support 3; and

[0041] An oblique support adjustment rod 4, one end of the oblique support adjustment rod 4 is connected to the PC track beam 2, and the other end is connected to the bridge pier 1, and the oblique support adjustment rod 4 can be extended or shortened to adjust The inclination angle of the PC track beam 2 relative to the pier 1 .

[0042] By setting the connec...

Embodiment 2

[0044] like image 3 As shown, based on Embodiment 1, the steel pipe spherical hinge support 3 includes a supporting steel cylinder 31, a screw 32, a metal ball 33 and a block 34, and the supporting steel cylinder 31 includes a base and a threaded hole protrusion, and the threaded The hole protrusion is vertically arranged on the base, the base of the supporting steel cylinder 31 is arranged on the top of the pier 1, and the screw 32 is arranged in the threaded hole of the supporting steel cylinder 31, and the leading screw 32 32 is provided with the metal ball 33, the bottom of the block 34 is provided with a spherical groove, and the top of the metal ball 33 is embedded in the spherical groove.

[0045] The lead screw 32 is arranged in the threaded hole of the supporting steel cylinder 31, and by turning the lead screw 32, the amount of extension or insertion of the lead screw 32 in the threaded hole is controlled, and then the metal ball arranged at the other end of the lea...

Embodiment 3

[0048] Based on Embodiment 2, one end of the oblique support adjustment rod 4 is detachably arranged on the side wall of the PC track beam 2 , and the other end is detachably arranged on the pier 1 .

[0049] By setting pre-embedded threaded holes for fixedly connecting the two ends of the oblique support adjustment rod 4 on the PC track beam 2 and the pier 1, the two ends of the oblique support adjustment rod 4 can be fixed or disassembled by bolts to avoid Traditionally, after the construction is completed, the pre-embedded parts similar to the pre-embedded threaded holes in this application are forced to be pulled out from the PC track beam 2 and the bridge pier 1, causing damage to the surface of the PC track beam 2 and the bridge pier 1.

Abstract

The invention relates to the technical field of straddle type monorail traffic track beams, in particular to a straddle type monorail continuous steel structure PC track beam adjusting device and an adjusting method thereof. The device comprises a pier; a steel pipe spherical hinge support which is fixedly arranged at the top of the pier; a pre-buried supporting block; and an inclined supporting adjusting rod, wherein one end of the inclined supporting adjusting rod is connected with the PC track beam, the other end of the inclined supporting adjusting rod is connected with the pier, and the inclined supporting adjusting rod can extend or retract to adjust the inclination angle of the PC track beam relative to the pier. The steel pipe spherical hinge support capable of enabling the end of the PC track beam to be rotationally connected to the bridge pier is arranged at the joint of the bridge pier and the end of the PC track beam, and the included angle between the bridge pier and the PC track beam is adjusted through the oblique supporting adjusting rod, so that the inclination angle of the PC track beam can be freely adjusted before the post-pouring section construction of a rigid frame system, namely the PC track beam. The difficulty of linear adjustment of the rigid frame system before construction of the post-pouring section is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of straddle-type monorail traffic track beams, in particular to a straddle-type monorail continuous steel structure PC track beam adjustment device and an adjustment method thereof. Background technique [0002] Commonly used construction methods for conventional continuous rigid structures include cast-in-place, simply supported variable continuous and segmental assembly. Since the track beam has very strict requirements on the size and linear control accuracy, it is difficult to meet the requirements by casting on site or segmental assembly. When a continuous system is used, it must be prefabricated in the factory, supplemented by the simple support of the cast-in-place connection. Continuous way. That is, the single-span beams that meet the precision requirements are prefabricated in the factory, then transported to the site, hoisted in place, and then poured concrete at the joints to form a continuous s...
