Description

Use prefabricated steel-concrete combination T beam and the construction method of Wavelike steel webplate

Technical field

The invention belongs to the bridge technology field of highway and urban road, be primarily related to use the prefabricated steel-concrete combination T beam of Wavelike steel webplate and construction method.

Background technology

The full welded steel beam of I shape is lightweight, bearing capacity is big, is widely used with the combination beam of concrete slab composition, but the web of this i-shape steel beam the most all uses plain plate in highway and Urban Bridge, advantage be weld between plain plate relatively easy;Shortcoming is that plain plate welding residual stress is big, needs to use more ribbed stiffener to improve Web Stability, and prestressing force efficiency is low, and girder steel can be caused extra additional stress by the shrinkage and creep of concrete slab, and the concrete of position of the fulcrum is easy to crack.

The construction method of steel-concrete composite beam mainly has two kinds at present, and one is full span erection method, and the whole hole of the method sets up, advantage is that speed of application is fast, shortcoming be beam length between 25m ~ 40m, transport difficulty is big, easily there is stability problem in erection process, and actual application is seldom;Another is raft support method, the method is at regular intervals, set up passive scaffold, form operating platform, girder steel be then installed on support and weld, then pouring into a mould concrete roof, the method advantage is to need not Large-scale Hoisting equipment, carrying out segment girder steel welding coupling, the problem solving the transport of long beam on support, shortcoming is that construction period length, Site Welding amount be big, full framing affects traffic above-ground and surrounding enviroment.

Summary of the invention

The present invention is directed to the deficiency that existing Steel-concrete Combined Beam Structures form exists with construction method, it is proposed that use prefabricated steel-concrete combination T beam and the construction method of Wavelike steel webplate.The advantage both with traditional Steel-concrete Combined Beam Structures, the stability of web can be improved again and avoid the impact of concrete shrinkage and creep, can effectively overcome present on the current construction method of steel-concrete composite beam not enough simultaneously, have convenient transportation, be easily assembled, Site Welding amount is little, concreting amount is little, speed of application fast, to remarkable advantages such as ground traffic impact are little.

The present invention adopts the technical scheme that for achieving the above object: use the prefabricated steel-concrete combination T beam of Wavelike steel webplate, the prefabricated steel-concrete combination T beam section unit combined including multiple I shape Wavelike steel webplate girder steels and concrete slab, adjacent beams segment unit forms entirety by the wet seam of junction steel plate and casting concrete.

Prefabricated steel-concrete of the present invention combination T beam section unit is prefabricated T-shaped section beam.

Connected by lateral connection reinforcing bar and the wet seam of horizontal concrete of Prefabricated composite beam element between the concrete slab of Prefabricated composite beam element of the present invention, connected by the longitudinally connected reinforcing bar of Prefabricated composite beam element and the wet seam crossbeam of beam-ends.

The longitudinally connected position of I shape Wavelike steel webplate girder steel of the present invention is at falsework top.

The present invention realizes using the construction method of the prefabricated steel-concrete combination T beam of Wavelike steel webplate, and be first prefabricated in the factory the steel-concrete combination T beam containing Wavelike steel webplate;Secondly, construct at bridge location permanent abutment and bridge pier, setting up falsework form limited bracket system at bridge pier, steel-concrete prefabrication completed combination T beam segmentation is arranged on strutting system, combination beam be vertically and horizontally reserved with connection reinforcing bar;Then, the vertical and horizontal steel construction part that prefabricated steel-concrete combines T beam bolts or welds, to form beam lattice system;Finally, the vertically and horizontally reserved steel bar that prefabricated steel-concrete combines T beam carries out colligation and is welded to connect, the cast Prefabricated composite beam element top board wet seam of horizontal concrete and beam-ends wet seam crossbeam, complete the connection construction between beam body after concrete strength reaches requirement, removes falsework.

The present invention realizes using the construction method of the prefabricated steel-concrete combination T beam of Wavelike steel webplate, the process that described steel-concrete combines T beam section unit prefabricated is, I shape Wavelike steel webplate girder steel is put smooth, Shear connection key between I shape Wavelike steel webplate girder steel top flange welding concrete and girder steel, by the reinforcing bar in concrete roof and Shear connection key colligation or weld together, lay concrete roof template, pour into a mould the concrete slab of Prefabricated composite beam element and carry out maintenance, concrete reaches intensity form removal, complete steel-concrete combination T beam section unit prefabricated;

Girder steel is fixed during described erection and casting concrete by the present invention temporarily, by I shape Wavelike steel webplate girder steel laterally across laterally connecting to form beam lattice system temporarily.

The present invention carries out small size jacking to the fulcrum of falsework before described I shape Wavelike steel webplate girder steel connects the cast of complete, composite beams beam-ends wet seam crossbeam, then wet seam crossbeam is poured into a mould, after concrete strength reaches requirement, the fulcrum of falsework is resetted, distribute with the internal force between adjusting and optimizing girder steel and concrete slab.

The present invention relatively prior art has the advantage that:

(1) beam section simple structure, dimensional standard is unified, it is easy to factory normalization is prefabricated, meets Conventional transport requirement, it is to avoid the long wide construction brought of beam body and transportation problem, and exploitativeness is improved;

(2) base plate tensile zone uses steel construction, and top board pressurized zone uses xoncrete structure, and web easy unstability region uses corrugated sheet steel structure, takes full advantage of the characteristic of multiple material or structure, and stock utilization is high, and anti-flexion capabilities significantly improves;

(3) beam body is lightweight, uses small mechanical equipment just can complete lifting construction, coordinates the connecting portion of limited bracket construction method multipoint parallel to construct, operation is few, and site operation workload is little, and it is fast that construction sets up speed, limited bracket is little to ground area occupied, little to original traffic impact.
