Description
Technical field
The utility model relates to field of bridge construction, particularly, relates to a kind of bridge and chooses arm installation auxiliary support apparatus and supporting component.
Background technology
Steel box girder bridge refers to that girder is the beam bridge of thin-walled closed section form, and girder is often called box-girder or box-girder.Compared with the girder truss of routine, box-girder more can play the supporting capacity of steel plate effectively, and larger bending resistance and torsional rigidity can be provided based on the characteristic of its closed hollow section, in addition, the structure of box-girder is simple, paint is convenient, and due to its inside be closed space therefore more difficult corrosion.
Therefore, in field of bridge construction, usually use box-girder as the girder form of bridge, the box-girder also often adopted in Longspan Bridge (as suspension bridge, cable stayed bridge) is as the girder form of bridge.Can shown in reference diagram 1, box-girder is formed as T-shape, and what it comprised web grider 11 and was fixedly connected on web grider 11 both sides chooses arm 12.In actual applications, box-girder has the width (distance between the end referring to choose arm 12 to another end choosing arm 12) of 30-50m usually, and due to construction plant limited space, therefore box-girder needs to carry out in factory assembled in advance usually, that is: first, to need web grider 11 to be placed on moulding bed 13 so that the lifting of steel box-girder and avoid rubbing between steel box-girder and ground 15, afterwards, to arm 12 be chosen be welded on respectively the both sides of web grider 11, finally by haulage device, the box-girder after assembled will be transported to job site.In the pre-splicing process of assembling of box-girder, because the outer length of choosing of choosing arm 12 itself reaches more than 3m, terrain clearance is not less than 4m simultaneously, and the below of therefore choosing arm 12 in the pre-splicing process of assembling of box-girder needs to arrange temporary support, is supported on position to be welded will choose arm 12.In the prior art, usually adopt to have and supported choosing arm 12 by the support member 14 (as shown in fig. 1) with level altitude of shaped steel and Plate Welding.But, when box-girder has different cross sections, shaped steel and steel plate to be reselected according to the structure of choosing arm 12 to make the support member 14 with new height, in this case, not only need repeatedly installing/dismounting, and work consuming be time-consuming, increase cost of manufacture.Therefore, the applicability of support member 14 of the prior art is very low.In addition, the method also having some making factories often to use the backing plate of the rod member and respective numbers with level altitude to superpose in the pre-splicing process of assembling of box-girder supports chooses arm 12, due to rod member and backing plate himself elasticity and the gap that exists between it, therefore the non-constant of the stability of this support member, what support accordingly chooses arm 2 stability also non-constant, this makes the welding of choosing arm 12 there is larger error even mistake, greatly reduces the welding quality of box-girder.
Therefore, in prior art, in the pre-splicing process of assembling of box-girder, support member has some limitations the support of choosing arm.
