The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model feature and other correlated characteristic are described in further detail, so that technician's of the same trade understanding:
As Figure 1-10 shows, number in the figure 1-20 is respectively: after pier stud 1, crossbeam 2, pulling force bearing 3, reserved short column 4, crossbeam after pouring concrete 5, pier stud in pouring concrete 6, vertical coaming plate 7, bolt 8, dowel 9, cavity after pouring concrete 10, reserved chamber 11, installing hole 12, the main muscle 13 of bridge pier, bolt hole 14, level board 15, base plate 16, junction plate 17, lower wing plate 18, box built-in fitting 19, bearing anchor case 20.
Embodiment: as shown in Figure 1, cross-saddle single-track traffic in the present embodiment forms with the door type structure that overhead segment structure consists of pier stud 1, crossbeam 2, its middle cross beam 2 is by pier stud 1 fixed bearing that is positioned at its two ends, two pulling force bearings 3 of crossbeam 2 top fixed installations, each pulling force bearing 3 supports respectively a monorail track beam.
As shown in Fig. 9,10, pier stud 1 is a performance of concrete column confined, and its capital is provided with a box built-in fitting 19 straight up, on box built-in fitting 19, there is a reserved short column 4, reserved short column 4 is as the coupling part with crossbeam 2, and its periphery is also provided with junction plate 17, has bolt hole 14 on junction plate 17, as Figure 4-Figure 6, crossbeam 2 is pre-manufactured steel crossbeam, and its both sides lower wing plate 18 is reserved and had installing hole 12 respectively with the corresponding installed position of reserved short column 4, and the lower wing plate 18 of installing hole 12 both sides has the bolt hole matching with bolt hole 14 positions, as shown in Figure 2, the installing hole 12 respectively reserved short column corresponding with both sides 4 suits coordinates, make to form and be fixedly connected with between crossbeam 2 and pier stud 1, lower wing plate 18 on crossbeam 2 and the horizontal coaming plate 15 on pier stud 1 are formed and are fastenedly connected and make to be integrally formed structure between crossbeam 2 and pier stud 1 by pouring concrete 5 after building crossbeam by bolt 8, when guaranteeing the supporting force of 1 pair of crossbeam 2 of pier stud, realize prefabrication, the mode of on-site hoisting is carried out building of overhead segment structure, not only shortened the construction period, also reduced the impact of traffic above-ground and eliminated the potential safety hazard that in road, Full space support construction brings.
As shown in Figure 4,5, prefabricated crossbeam 2 tops offer two reserved chambeies 11, and reserved chamber 11 is respectively as the installation position of supporting the pulling force bearing 3 of two monorail transit circuits.As shown in Figure 3, the dowel 9 that is embedded with some horizontal arrangement in reserved chamber 11 makes reserved chamber 11 form bearing anchor case 20, pouring concrete 10 after building again in cavity after pulling force bearing 3 is positioned in bearing anchor case 20, pulling force bearing 3 and bearing anchor case 20 are integrally formed, when guaranteeing that pulling force bearing 3 installation accuracies require, also strengthened the support effects of 2 pairs of pulling force bearings 3 of crossbeam.
As shown in Fig. 7-10, the periphery of the reserved short column 4 of the capital of pier stud 1 is provided with a box built-in fitting 19, and this box built-in fitting 19 plays the reserved short column 4 of positioning support, and the effect that itself and pier stud 1 are integrally formed.This box built-in fitting 19 consists of vertical coaming plate 7, level board 15 and base plate 16, wherein vertical coaming plate 7 around the capital circumferential direction setting of pier stud 1 and respectively with pier stud 1 on the reserved main muscle 13 of bridge pier fix, the casting area of vertical coaming plate 7 pouring concrete 6 after the capital of pier stud 1 forms pier stud; Base plate 16 is fixed on the middle part, region consisting of vertical coaming plate 7, and its plate body surrounding is welded and fixed with vertical coaming plate 7 respectively, and its upper surface is fixedly connected with the reserved short column 4 of supporting; The semiclosed region upper shed that level board 15 encapsulation consists of vertical coaming plate 7, because the height of reserved short column 4 is greater than the height of vertical coaming plate 7, so the coverage of level board 15 plate bodys is the cylinders to reserved short column 4 by the upper limb of vertical coaming plate 7.Casting area in the coaming plate structure being formed by vertical coaming plate 7, level board 15 and base plate 16 by pier stud after pouring concrete 6 fill, realize fixing between reserved pier stud 4 and pier stud 1.
The present embodiment is in the specific implementation: pre-buried pier stud 4 vertical coaming plate 7 around first welds with the main muscle 13 of pier stud, then welds all the other coaming plates again, and calibration after-pouring concrete completes pre-buried pier stud 4 installations.
The crossbeam 2 that lifting is made in factory process in advance, is directly sleeved on gooseneck 2 two ends lower wing plate installing holes 12 on the reserved short column 4 at pier stud 1 top while setting up, and tightens the bolt 8 of beam-ends and locates temporarily.
During installation, fixing dead between crossbeam 2 and pier stud 1, after rail beam and other the second stage of dead load have been constructed, be converted to and be rigidly connected again, this kind of mode reduced pier stud bending square, improves structure stress.
The interior dowel 9 that welded in reserved chamber 11 on crossbeam 2, lifting pulling force bearing 3, builds rear pouring concrete 10 in cavity again after calibration.
