Technical field

The present invention relates to railway engineering technology fields, and in particular to one kind is across both wired transom pier large-span steel transverse beam liftings Construction method.

Background technology

High-speed railway, inter-city passenger rail are when with both wired scissors crossings, for the normal pass and safety for ensureing both wired, It is a kind of conveniently method using the existing line of gate-type pier structure, transom pier plastic simplicity is slim and graceful, and stability is good, but common Across busy both wired security risk height, to put the restraining factors such as the construction time is long, construction site is narrow.

Transom pier crossbeam uses steel construction, and pier top is equipped with interim pinner, temporary support is equipped on interim pinner, interim to prop up Seat includes bearing upper plate, bearing arc plate, steel pin and bearing lower plate from top to bottom, and bearing arc plate and bearing lower plate are equipped with hole, It is connected by steel pin, is set a roof beam in place for release, influence of the load of the generations such as temperature to gooseneck, gooseneck and pier top connects bearing It is divided into hold-down support and movable bearing support:One end is hold-down support, and one end is movable bearing support.When lifting, fixing end uses will be interim The bearing upper plate and bearing arc plate of bearing are welded on crossbeam bottom plate, and the steel pin of contraposition connection when lifting, movable end will be on bearing Plate and bearing arc plate do not weld, and are bonded polyfluortetraethylene plate above bearing arc plate, and bearing upper plate directly aligns bearing arc when lifting Plate, due to the factors such as deformation, temperature change after measurement error and gooseneck lifting, contraposition is difficult, only by bearing when processing The preformed hole amplification that lower plate is connect with steel pin, changes the position of steel pin, will certainly influence the erection precision of gooseneck in this way, and Construction time is long, and especially transom pier lifting is generally across both wired main points constructions, it is necessary to complete lifting at the appointed time, exist Prolong a risk.

Invention content

Against the above deficiency, the object of the present invention is to provide one kind across both wired transom pier large-span steel transverse beam liftings Construction method, which shorten the lifting times of gooseneck, and speed of application is fast, and improves construction precision.

To achieve the above object, technical solution provided by the present invention is:

One kind includes the following steps across both wired transom pier large-span steel transverse beam lifting construction methods:

Step S1:Temporary support is mounted on according to setting position on the interim pinner being arranged on transom pier;

Step S2:In the pier top of transom pier according to design position accurate settingout go out gooseneck pier top cross axis, Setting-out is corresponded on gooseneck and goes out cross axis, and the installation for gooseneck positions;

Step S3:Gooseneck is sling using hoisting machine, when dropping place, the outside of gooseneck utilizes crowbar, inner utilization jack Position is adjusted, until the cross axis on gooseneck and in pier top is perfectly aligned, completion falls beam;

Step S4:Gooseneck bottom plate and temporary support are welded.

Preferably, position block is welded in the pier top, limit can be played the role of when gooseneck lifts, improve installation Efficiency, the gooseneck interior welds have positioning drawing plate and jack, the position for adjusting gooseneck.

Preferably, the temporary support includes sequentially connected bearing upper plate, bearing arc plate and bearing lower plate from top to bottom, Wherein, mortar bed, and the interim pinner and sand are equipped between the bearing lower plate of the temporary support and the interim pinner It is embedded with bolt on slurry bed course, bolt is fixed in across the bearing lower plate on interim pinner.

Preferably, the thickness of the mortar bed is 30mm.

Preferably, the lower plate of gooseneck is welded with the bearing upper plate in the step S4.

Beneficial effects of the present invention are:

Temporary support is mounted on according to setting position on the interim pinner being arranged on transom pier by the present invention, and by door Gooseneck is gone out in the cross axis of pier top according to design position accurate settingout in the pier top of formula pier, setting-out is corresponded on gooseneck and goes out ten Word axis slings gooseneck using hoisting machine, and when dropping place, the outside of gooseneck utilizes crowbar, inner utilization jack to adjust position, Until the cross axis on gooseneck and in pier top is perfectly aligned, completion falls beam.By the contraposition of cross hairs, construction precision obtains Ensure, effectively every measurement data of gooseneck achieves in the deviation range of design requirement after the completion of control lifting Good effect, while the lifting time is shortened, speed of application is fast.

Below in conjunction with the accompanying drawings with embodiment, the present invention is further described.

Description of the drawings
