Abstract
The multiple-slab beam built-up bridge span erecting machine can constitute P and C beams of 40-48 m span in bridge location by means of section built-up process and erect prefabricated 32 m T-beam. It is constituted mainly by re-overlapped multiple-slab beam supporter, joist with sort beam hanging openable over pier, gantry crane, beam section transfering equipment, position regulating and locking device and supporter-sliding equipment.
Description
The invention belongs to a kind of traversing carriage formula bridging equipment of piecing together group.It has section assembling makes the system T of beam, factory type roof beam structure and function such as establishes, and the railway prestressed steel reinforced concrete beam that adapts to span especially and be 40-48 rice is the construction of P.C beam.
The railroad bridge load is heavy, highly big and width is narrow.The restriction system of equipment owing to set a roof beam in place, past railway letter mostly is 32 meters greatly with P.C beam maximum span, and several seats are 40 meters.Big or bridge pier is when higher when the bridge length overall, and bridge pier is too close too much, and unfavorable to the flood discharge navigation, cost also can improve.Span is reached more than 40 meters, and traversing carriage formula bridge fabrication machine is the most effective a kind of way.
It is that the fifties end, Germany is at first developed that traversing carriage formula pier top original position is made beam equipment, and development is very fast in states such as American-European Japan, but is used for road bridge more, and Japan once was used for railway bridge, and the span length is 30-34 rice only.And generally only limit to section assembling, the whole hole a kind of function in cast-in-place.Though highway in China department introduces two covers, the incompatibility railroad bridge.
Purpose of the present invention: provide having of existing six or four formula railway military beams (being called for short six or four formula military beams) the equipment assembly group of a kind of utilization multi-functional, the assembly unit traversing carriage formula bridge location Dun Ding that span reaches more than 40 meters makes beam equipment.Heavy, highly big and narrow, the general continuous hole count of width is not a lot of characteristics to adapt to railway beam load.
The object of the present invention is achieved like this: support adopts six or four formula military beam equipment assembly groups of my institute's development, and bilayer is repeatedly put again, and multiple-piece contains girder, nose girder and tail boom.If bracing.Hang subiculum joist support joist joint with tail trimmer.Following joist can Unscrew to cross bridge pier.Support is divided into slippage equipment.If straddle truck, beam joint transporting apparatus, rackwork and locking device.The batch production of beam joint is prefabricated.Bridge location Zhuliang internode can wet and connect (fluid concrete section) or splicing.Concrete pouring, steel tendon tensioning process design by traversing carriage job practices characteristics.
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing: the overall formation schematic diagram of this bridge fabrication machine.
This machine is made of traversing carriage 2, a cushion device 3, following joist 4, supporting bearing beam 5, slippage equipment 6, beam tail slide block 7, the dilatory hoist engine 8 of gantry crane 1, six four formula military beam equipment assembly group, and 9 is bridge pier.Utilize the traversing carriage 2 of six or four formula military beam equipment assembly groups repeatedly to put again for two-layer equation, multiple-piece, contain girder, nose girder and tail boom, between two group of six or four formula military beam special gusset piece is arranged up and down, eight on support 2 usefulness six or four formula beams, about dividing two groups, last plane has to intersect from beginning to end puts down connection, and only there is straight support the centre, and beam joint position, whereabouts need be avoided in the position.Hang down joist 4 support beams joint down with tail trimmer, following joist 4 can Unscrew to cross bridge pier 9; Tail trimmer rides on six or the four formula military beam lower edges and is provided with two pin-and-holes; Inboard pin-and-hole hangs joist 4 down, and outside pin-and-hole is used to do down the joist rotary pin shaft; Repeatedly put longeron on the following joist 4; Support 2 times is established cylinder slideway 6 and is formed slippage equipment with beam tail slide block 7 on the pier top 9, supporting bearing beam 5 is arranged on it; With straddle truck 1 lifting beam joint and feeding beam joint, adjusting and the supporting beam joint on the joist 4 down.
This bridge fabrication machine is made the constructing operation of beam with sections assembly group method:
Six or four formula military beam supports, 2 assembly groups, specified node and pier cap center align, and a jail is on the supporting bearing beam 5 of slippage equipment 6 tops.
The concrete beam joint is delivered to support 2 afterbodys by joint by dolly.
By sling beam joint of straddle truck 1, straddle truck 1 walks to walk to the precalculated position.
Straddle truck 1 puts down the beam joint, drops down onto down on the joist 4.
Straddle truck 1 is back to the support afterbody, lifts by crane next beam joint.
Till all beam joints of this hole beam have hung.Between each beam joint at a distance of about 60 centimetres, so that do wet joint.
The position jack adjustment of each beam joint, then well with 3 pads of cushion device.
Make wet joint.Upright good inner formword ties up reinforcing bar, bellows at beam septa intersegmental position, upright better external mold, concrete perfusion.After treating that it reaches predetermined strength, stripping is worn the king wire bundle and is carried out stretch-draw by design.
Adjust a cushion device 3, P.C beam and support are broken away from, open down joist 4 then and rotate sagging.Play ceiling hold 2 and remove supporting bearing beam 5, support 2 falls within on the pier top slippage equipment 6, and beam tail slide block 7 falls within on the P.C back portion track of making.
With dilatory hoist engine 8 support 2 is dragged to next hole P.C beam design attitude, plays ceiling hold 2 and use supporting bearing beam 5 to support, carry out the assembly group of another hole P.C beam.
When setting up the T beam, straddle truck is established two, and elevating capacity need be determined by lift heavy, and first hanging beam front end moves forward to recurrence hanging beam rear end behind the certain position, and the back that puts in place is traversing, and the beam that falls then is in place.
The effect of invention
Adopt assembly unit method pier top in-situ beam fabrication in prefabricated subsection, the bridge opening, the beam body structure is simplified, and saves steel, cement and auxiliary material, and the duration shortens, quality improves, the labour also saves in a large number, and operation is safer.
The railway span 40-48 rice that can reach is external rare, domestic also belong to big.
Can realize that the section assembling method makes beam and 32 meters T roof beams structure of factory's system and multiple function such as establish.
Use six or four formula military beams widely owing to make full use of China, the Inherent advantage of performance emergency steel girder, six or four formula military beam traversing carriage formula bridge fabrication machines are applied widely, the manufacturing cycle is short, cost is low, in light weight and be convenient to dismounting transportation, thereby help promoting the use of.
This top new equipment and technology, it is limited because of the equipment of setting a roof beam in place in the past to help to change China, and railway serves as that main formed pier height is striden the short situation of not managing entirely with 32 meters concrete beam, thereby promotes the design of railway concrete beam and the innovation of making and the development of railway construction.
