Abstract
The invention relates to a method for making a winged steel tube-concrete composite beam. The method comprises the following steps: a winged steel tube-concrete support beam (3) is machined into U shape by a thin-walled steel plate, and the steel plate at two ends of the U-shaped steel plate is respectively folded into shoulder parts (4); and the steel plate at the shoulder parts (4) is fixedly connected with a steel support plate or a wood plate (2), a reinforced concrete floor plate (1) is directly poured after an inner reinforcing steel bar of the support beam is completely bound with a floor reinforcing steel bar so as to integrate inner beam concrete of the winged steel tube-concrete support beam (3) with floor plate concrete to finally form the winged steel tube-concrete composite beam. The steel plate at the shoulder parts (4) is connected with the steel support plate or the wood plate (2) by tapping screws (6). The inner wall of the winged steel tube-concrete support beam (3) is welded and tensioned from opposite directions with deformed reinforcing bars (5). Compared with the traditional support beam, the winged steel tube-concrete composite beam has greatly improved strength, rigidity and stability in the case of the equivalent materials. Experimental data proves that the overall strength and rigidity of the winged steel tube-concrete composite beam improve by 1.5-2.5 times, and the cost is decreased by about 40% under the condition of achieving the same strength, rigidity and stability.
Description
Affiliated technical field
The present invention relates to a kind of way with wing steel pipe concrete composite beam.
Background technology
At present, the way of well-known building structure spandrel girder nothing more than 1, reinforced concrete beam, 2, shaped steel concrete beam, 3, section steel beam.Preceding two kinds traditional construction technology complexity, the man power and material is consume significant; The third pure section steel beam is then because of the easy unstability of its insufficient rigidity, and becomes the problem of the numerous building expert scholar's research in the whole world always.
Summary of the invention
In order to overcome the deficiency of existing conventional art spandrel girder combination property, the purpose of this invention is to provide a kind of way with wing steel pipe concrete composite beam.This spandrel girder is as the part of floor slab structure, and not only cost is low, the duration fast (but suitability for industrialized production), and more can increase the resistance to overturning of building.And more superior fire prevention shockproof properties arranged.
The technical scheme that the present invention solves its structure technology problem is:
Band wing steel pipe concrete spandrel girder adopts the thin-walled steel plate to be processed into the U type, and U type two ends steel plate folds the flat part of choosing respectively; Flat choose the part steel plate and fixedly connected with steel board or plank, after reinforcing bar and flooring reinforcing bar binding are finished in U type beam, directly build the steel bar concrete floor plate, make concrete and integral body of floor face concrete formation in the U type band wing steel pipe concrete spandrel girder beam, and become a kind of band wing steel pipe concrete composite beam.
Describedly flat choose the part steel plate and be connected with self threading pin with steel board or plank.
Described spandrel girder inwall with screw-thread steel rib welding to drawing, to strengthen its tension stress and to the restraint forces of concrete in the beam.
Compare with traditional spandrel girder, under the situation of using equivalent material, its intensity, rigidity and stability are all strengthened greatly.Show that according to existing experimental data its bulk strength and rigidity improve 1.5-2.5 doubly.Its cost reduces about 40% under the situation that reaches equality strength, rigidity and stability.No longer need simultaneously template to install and remove.Saved great amount of manpower and material resources.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Among the figure: 1. steel bar concrete floor plate 2. steel boards or plank 3. are with wing steel pipe concrete spandrel girders
4. flat part 5. indented bars tie rods 6. self threading pins of choosing
The specific embodiment
Band wing steel pipe concrete spandrel girder 3 adopts the thin-walled steel plate to be processed into the U type, and U type two ends steel plate folds the flat part 4 of choosing; Flat choose part 4 steel plates and fixedly connected with steel board or plank 2, after reinforcing bar and flooring reinforcing bar binding are finished in band wing steel pipe concrete spandrel girder, directly build steel bar concrete floor plate 1, make concrete and integral body of floor plate steel bar concrete formation in band wing steel pipe concrete spandrel girder 3 beams, and become a kind of band wing steel pipe concrete composite beam.
Describedly flat choose part 4 steel plates and be connected with steel board or plank 2 usefulness self threading pins 6.
Described band wing steel pipe concrete spandrel girder 3 inwalls with indented bars tie rod 5 welding to drawing, to strengthen its tension stress and to the constraint of concrete in the steel pipe.
The concrete construction point that is connected with post and floor plate is as follows:
1. when structural column is reinforced concrete pile:
Must then the direct tacking of beam of the present invention be connected on the embedded board at corresponding depth of beam pre-embedded steel slab of reinforced concrete pile and reserved steel bar, all the other operations are all carried out according to existing steel bar concrete standard.
2. when structural column is shaped steel or concrete filled steel tubular column:
The direct tacking of beam of the present invention need only be connected on the corresponding absolute altitude of steel column, and carry out the part at the node place according to existing Construction of Steel Structure standard and strengthen handling.
3. beam of the present invention is connected with floor plate, utilizes beam of the present invention two ends to choose the support platform of part steel plate as floor template, utilizes its overlap to adopt self threading pin to connect.After the concrete cast, its bed die need not removed, and forms one and decorates a day surface layer naturally.And wooden model or steel board itself have enough tensile strength, and the globality and the degree of safety of structure had major contribution.
