Description

The invention relates to bridge construction and can be used to attach a fixed support part — a shear stop to a metal crossbar of a bridge support.

Known is the attachment point of the fixed support part — the shear stop to the reinforced concrete crossbar of the bridge support, including the base plate fixed with anchor bolts concreted in the wells on the reinforced concrete crossbar of the bridge support, the shear stop, including the support part with the upper support plate attached to the support beam of the span and a lower base plate attached to the base plate / 1 /.

Accurate aiming of the fastener by height and horizontal is ensured by means of leveling gravy between the bottom of the support beam and the upper surface of the plate.

The disadvantage of this mounting unit of the supporting part of the bridge is the impossibility of its use on a metal crossbar of the bridge support due to the inability to place large wells in the body of the metal crossbar for concreting anchor bolts.

The objective of our invention is to provide reliable and cost-effective fastening of the fixed support part - the shear stop on the metal crossbar of the bridge support with the ability to accurately align the support part - the shear stop in plan and height. The problem is solved due to the fact that in the attachment site of the fixed supporting part of the bridge, including a shear stop, comprising a supporting part with upper and lower supporting plates, a crossbar and a base plate attached to it, the base plate is welded to a crossbar made of metal, equipped with a steel cage and a mounting plate placed in a steel cage with a gap around the perimeter and vertically, the lower base plate of the supporting part is fixed to the mounting plate, which is equipped with vertical quotation sheets lakes, and the base plate has horizontal quotation pins, the base plate and installation plate are interconnected with the metal bolt by anchor rods and anchor bars, and on the base plate and installation plate on the surfaces facing each other, there are stops located with mutual displacement and the cavity between the base plate and the steel ring of the installation plate is filled with a binder solution, while the holes for the anchor studs in the installation plate and in the base plate are enlarged wow size.

The invention is illustrated in the drawing, where:

- in FIG. 1 shows the span in the area of support of the bridge support on the crossbar, view along the longitudinal axis of the bridge;

- in FIG. 2 shows a perspective view of the attachment site of the supporting part of the bridge - shear stop;

- in FIG. 3 shows a mounting unit for a supporting part of a bridge — a shear stop, side view;

- in FIG. 4 shows FIG. 3, view along AA.

The span of the bridge 1 for the perception of vertical loads is equipped with comprehensively movable supporting parts 2, and for the perception of horizontal reactions it is equipped with a mounting unit for the supporting part of the bridge 3 in the form of a shear stop 4. One of the features of this invention is the use of a metal crossbar 5 with an insufficient bearing support the ability of the top sheets when using anchor fastening of the node of the supporting part 3.

The attachment site of the supporting part of the bridge 3 includes a shear stop 4, the base plate 6, the mounting plate 7, the supporting part 3 with the lower 8 and upper 9 base plates.

The shear stop 4 is attached by the upper plate 9 to the supporting beam 10 of the span 1. The base plate 6 is attached to the metal crossbar 5 with welds and provided with a steel sleeve 11. The mounting plate 7 is placed in the steel holder 11 with a gap around the perimeter and in height.

To absorb the moment arising from horizontal forces, the base plate 6 and the mounting plate 7 are combined with anchor studs 12. Anchor studs 12 pass through the plates 6 and 7 and are attached to the top sheet of the metal crossbar 5. The holes 13 for the anchor studs 12 in the plates 6 and 7 are made larger size to adjust the position of the plates in the plan, and in the upper sheet of the crossbar 5 holes are made of a normal size. The mounting plate 7 is equipped with vertical quotation pins 14, and the steel sleeve 11 has horizontal quotation pins 15. To compensate for the increased size of the holes 13 in the plate 7, the anchor bar 16 is installed on top of the anchor pins 12.

The base plate 6 and the mounting plate 7 on the surfaces facing each other have stops 17 (on the bottom of the mounting plate 7 and on the top of the base plate 6 inside the steel sleeve 11) located with mutual displacement. These stops 17 and the steel sleeve 11 are used to absorb horizontal loads.

After mounting plates 6 and 7 in the design position, the cavity between the base plate 6 and the steel sleeve 11 of the mounting plate 7 is filled with a binder solution 18 through the gap around the perimeter of the mounting plate 7. The solution 18 fills the cavity to the top of the steel holder 11.

The attachment point of the supporting part of the bridge 3 is mounted as follows.

The base plate 6 is installed on the supporting surface of the metal crossbar 5 and is attached to the crossbar with welds. Next, mount the mounting plate 7. The mounting plate 7 is hung with the help of vertical 14 and horizontal 15 quotation pins in the cavity of the steel holder 11 and they are used to adjust the position of the mounting plate 7 at the necessary height and required dimensions in plan. Gaps around the perimeter and along verticals between plates 6 and 7 make it possible to compensate for deviations made during the manufacture and installation of the span 1. Then the shear stop 4 is mounted - with the lower plate 8, the stop is bolted to the mounting plate 7, and the upper plate 9 is bolted to the support beam 10 of the span 1. After that, the anchor studs 12 and the anchor straps 16 are mounted without tension on the design effort. Then, through the gap around the perimeter between the steel sleeve 11 and the mounting plate 7 fill the cavity inside the steel sleeve 11 with a binder solution 18.

After a set of binding strength 18 with the required strength, the anchor pins 12 are tensioned to the desired design position.
