Abstract

The present invention discloses one kind of combined beam of laminated steel-concrete plate for highway bridge and building as support member of bridge and building. Shear resistant connecting parts are welded to steel beam, prefabricated solid or hollow reinforced concrete boards are set on the steel beam, the steel bar tails are crossed and welded together, and the post-deposited concrete is deposited to form the combined beam. The combined beam has the advantages similar to those of in-situ deposited combined beam as well as saving in formwork and formwork supported step, simple prefabricated board structure, fast construction speed, etc. The present invention has wide application foreground in bridge structure and building structure fields.

Description

Steel-concrete folding plate combined beam

Technical field

The invention belongs to the building supporting member scope of bridge and building, particularly be applied to a kind of steel-concrete folding plate combined beam of highway bridge and industry and civilian construction floor system.

Background technology

The supporting member that existing reinforced concrete beam is made up of reinforcing bar and concrete, volume, from great.Compound beam is stressed jointly by girder steel and concrete are combined, and can reduce structure height, alleviate deadweight, and then reduce the sectional dimension and the foundation load of vertical supporting member.Compare with girder steel, then can reduce steel using amount, increase rigidity, and reduce structure height, corrosion resistance and durability are strengthened.Steel-concrete composite beam has made full use of steel tension and the good characteristics of concrete compressive property, but shortcomings such as common steel-concrete composite beam has that speed of application is slow, working procedure and complex structure." steel-concrete folding plate combined beam " that people such as Nie Jianguo propose then on the basis that keeps the compound beam advantage, overcome its above-mentioned shortcoming.Related content, in " building structure " such as Nie Jianguo (8,1995 (8): 19-23 and 32,2002 (4): 17-18) " steel-concrete folding plate combined beam and application thereof " reach " steel-aliasing plywood compound beam is in the conjoined structure application in engineering " and Nie Jianguo, Yu Zhouliang, " Tsing-Hua University's journals " such as leaf Tsing-Hua University (38,1998 (10): " steel-concrete folding plate combined beam Research on Aseismic Performance " reported 35-37).

Summary of the invention

The purpose of this invention is to provide a kind of steel-concrete folding plate combined beam.It is characterized in that: described folding plate combined beam is made of girder steel, precast plate and cast-in-situ concrete layer.Welding shear connector peg 2 on girder steel 1, precast plate 3 is laterally taken on the top flange of girder steel 1, and the beard muscle 4 that precast plate 3 plate ends stretch out has at least 1/3 to be welded to each other, and plays the effect of vertical shearing resistance; Precast plate 3 end faces are done in plucking processing or the precast plate can be provided with shearing resistance distributing bar 5, the switching performance of increase and back pouring concrete 6, and should guarantee the concrete density in notch place.

Described girder steel 1 comprises i section steel beam or box steel beam.

Described precast plate 3 comprises solid armored concrete slab or hollow steel bar concrete slab.

Described shear connector comprises peg or channel-section steel.

The present invention has the following advantages with respect to prior art:

Compare with cast-in-place compound beam, folding plate combined beam has solved problems such as steel-cast-in-situ concrete compound beam constructional difficulties, complex structure and steel-profiled sheet concrete combination beam cost be higher, save the high-altitude and propped up die process and template, reduced on-site concrete wet trade amount, be convenient to three-dimensional construction, shorten the construction period.Compare with the profiled sheet compound beam, can reduce cost greatly, reduce peg welding difficulty, and durability strengthens.Folding plate combined beam is applicable to multilayer and highrise building, multi storied industrial factory building, crane girder, steam power plant's centralized control box, colliery derrick, support of pipelines and bridge construction etc.It and steel-concrete coupled column (comprising steel core concrete column, profile steel concrete column etc.) are used formed combined structure system and more can demonstrate comprehensive benefit preferably.This structural mechanical property is good, simple structure is reasonable, construction economy is quick, can be applicable to bridge construction and other building structure.

The specific embodiment

The invention provides a kind of steel-concrete folding plate combined beam.Folding plate combined beam is to weld shear connector (peg or channel-section steel) 2 on girder steel 1, solid steel reinforced concrete or hollow steel bar concrete prefabricated board 3 are laterally taken on the top flange of girder steel 1 (i section steel beam or box steel beam), both bear working load, born vertical load as the part of floor again; The beard muscle 4 that precast plate plate end stretches out intersects mutually, and at least 1/3 be welded to each other, and plays the effect of vertical shearing resistance; Precast plate 3 end faces are done plucking and are handled, and also shearing resistance distributing bar 5 can be set in the precast plate, with the switching performance of increase with back pouring concrete 6; The concrete slab inherence is perpendicular to the negative moment of backing plate reinforcing bar of the configurable leap beam of beam direction of principal axis axle.Precast plate and in-situ layer combine becomes composite floor.When cast-in-situ concrete reached certain intensity, shear connector made superimposed sheet and girder steel be linked to be integral body and co-operation by the notch concrete, thereby formed girder steel-reinforced concrete sandwich plate compound beam.Shortcomings such as this form of structure has improved that the steel-concrete composite beam speed of application is slow, working procedure and complex structure.Under the guaranteed prerequisite of superposed surfaces shear strength, the normal section ultimate bending strength of folding plate combined beam is identical with cast in place concrete plate with destructive characteristics, and it is confirmed by test.Can obtain superposed surfaces shear strength lower limit at the precast plate upper surface during only with smoothing with float is 0.55MPa, estimates that higher limit will be far above lower limit.Before the superimposed sheet test specimen bends destruction relatively moving of superposed surfaces do not taken place all, the shear failure phenomenon does not more take place.In order to guarantee the close combination of precast plate and cast-in-situ concrete, should guarantee the cleaning of precast plate upper surface before cast-in-situ concrete.The present invention proposes to utilize " the beard muscle " that stretch out perpendicular to the negative reinforcing bar in the concrete slab of beam axis direction and precast plate end horizontal shear reinforcement of double as top and bottom respectively, be partial to simultaneously for the purpose of the safety, promptly the quantity of " beard muscle " should not be less than 1/3 of top cross reinforcing bar for the bottom transverse reinforcing bar.Consider the long duration load effect, the horizontal reinforcement ratio of suggestion folding plate combined beam is not less than 0.70%.Generally speaking, the number of steel bars according to bearing configuration in the Reinforced Concrete Continuous Plate can satisfy the quantitative requirement of vertical shearing resistance to transverse reinforcement.Owing to can guarantee the globality of structure after " beard muscle " that offside precast plate end stretches out is welded to each other, so the bearing length 〉=5cm of precast plate in the girder steel top flange gets final product.
