Technical field
The utility model belongs to the architectural shape technical field, is specifically related to a kind of trapezoidal corrugated sternum H-shaped steel composite beam.
Background technology
What generally adopt in similar field at present is common hot rolling i iron, hot rolled H-shaped and welded H section steel compound beam.Form primary structure member by bottom girder steel and upper reinforcement concrete slab by shear connector, girder steel generally adopts hot rolling i iron, hot rolled H-shaped and welded H section steel, and this design is found in patent---compound beam (ZL 95195718.X).
Common hot rolling i iron and H shaped steel form by hot rolling in factory, are subjected to the restriction of processing technology, and its web must be a module extender board.Welded H section steel then is that two blocks of frange plates and a planar webs are welded together composition H type cross section, when the hot-rolled steel section specification can't meet the demands, can adopt welded H section steel.But welded H section steel adopts the dihedral weld seam more, and the welding job amount is bigger.
Common hot rolling i iron and H shaped steel steel using amount are big, and main cause is that the anti-flexion capabilities of planar webs is lower, so need to improve web thickness.And there is same problem in welded H section steel, so need the ratio of height to thickness of web be limited when design, causes its web thickness general also thicker, so steel using amount is excessive.In addition, welded H section steel also will need to take the special technique measure in use, and such as stiffening rib or utilize Post-buckling Strength of Web Plate etc., design and construction are all comparatively complicated.
Traditional hot rolling i iron and H shaped steel is owing to be subjected to the restriction of processing technology and process equipment, the difficult maximization that realizes product, and when desired supporting capacity and rigidity were big, traditional product was difficult to meet the demands.If finish by design, processing welded H section steel, then comparatively time-consuming, improve cost, and influence construction speed.
Research and discussion replace traditional shaped steel as the girder steel in the compound beam with Ripple Sternum, and then are applied to the multi-rise building field, and realization reduces cost, optimizes performance, the length that increases the service life, and is those skilled in the art's goal in research.
Summary of the invention
The purpose of this utility model is to provide the trapezoidal corrugated sternum H-shaped steel composite beam of a kind of with low cost, superior performance, long service life.
The trapezoidal corrugated sternum H-shaped steel composite beam that the utility model proposes is connected and composed by top flange 1, web 2 and bottom flange 3, steel concrete wing plate 4 and profiled sheet 5, and its structure as shown in Figure 1-Figure 3.Wherein, top flange 1 is parallel with bottom flange 3, web 2 is vertically between top flange 1 and bottom flange 3, the section of web 2 is trapezoidal ripple, the inclination angle of tilting section is 30 °--90 °, its structure as shown in Figure 4, steel concrete wing plate 4 is positioned at profiled sheet 5 tops, profiled sheet 5 is positioned at 3 tops, bottom flange, steel concrete wing plate 4, profiled sheet 5, bottom flange 3 threes are fixing by peg 6, peg 6 can be used as shear connector with steel concrete wing plate 4, profiled sheet 5, girder steel top flange 3 connects into integral body, and transverse reinforcement 7 is welded in profiled sheet 5 tops, can be used as the connector between profiled sheet 5 and the armored concrete slab 4.
In the utility model, be respectively the single face fillet weld between described web 2 and top flange 3, the bottom flange 1.
In the utility model, corrugated web 2 adopts the numerical control bending technology to make.
In the utility model, the section of profiled sheet 5 is trapezium structure.
In the utility model, web 2 ripple density and height can change according to force request.
The utility model has been optimized the section mechanical property of girder steel in the compound beam by changing hot rolled H-shaped and welded H section steel web shape, by web be shaped, explained hereafter the utility model products such as full-automatic welding, anticorrosion, anti-fire processing.
In the utility model, described steel concrete wing plate 4 is a Reinforced Concrete Materials, and member 5 is a profiled sheet, can be used as the permanent template of steel concrete wing plate 4, connects by peg 6 between girder steel top flange 3, profiled sheet 5 and the steel concrete wing plate 4.
Preparation technology of the present utility model is as follows: will be with steel to be converted into trapezoidal corrugated web along its length, the inclination angle of tilting section can be spent to 90 degree from 30, and adopts fillet weld to be welded into H type cross section with two wing plates.It is relations of having optimized to a greater extent between section mechanical property and the product steel using amount that this novel section makes up maximum characteristics, makes it more to be tending towards rationalization, scientific.Therefore, this device has high bearing capacity, high rigidity, good stress performance, good anti-fatigue performance and from the characteristics that heavy and light combines, is very good structural shapes material.The present invention simultaneously adopts full automatic welding connection technology and professional positioning tool anchor clamps, can guarantee accurate positioning between web and two wing plates, and the seam track unanimity realizes standardization easily.Weld seam nothing attractive in appearance is splashed, and has welded product and has not needed shaping.The utility model adopts numerical control bending technology processing web, can realize that product maximizes.Bending production efficiency and industrial production welding efficiency are complementary simultaneously, can realize large-scale industrial production.
The utility model is compared with the compound beam of H shaped steel with adopting the hot rolling i iron, owing to can obtain higher anti-flexing bearing capacity with thin web thickness, so have higher economic advantages.The utility model is compared with the compound beam of H shaped steel with adopting the hot rolling i iron, and under the approximate situation of rigidity and bearing capacity, the girder steel steel using amount can be saved about 40%～60%, saves about 30% than welded H section steel.
The utility model has substantial difference and advantageous feature in the following aspects:
Can so just reduce half welding capacity, and reduce welding residual stress and permanent set adopting the single face fillet weld between web 2 and top flange 1, the bottom flange 3 when 1) producing, reduce cost simultaneously.
2) adopt extraordinary numerical control bending fabrication techniques corrugated steel web 2, can be implemented in and stressedly reduce wavelength than large part, strengthen ripple density or increase wave height, and at the more sparse ripple of stressed less position employing, realized along the optimization of beam length direction, thereby can reach the double effects that improves bearing capacity and save steel.
3) in the making of corrugated steel, adopt the numerical control bending technology can realize the maximization of member, for example can produce the big section steel beam that depth of section reaches 3 meters to 4 meters.
Forming techniques such as the 4) making of trapezoidal corrugated web 2 employing numerical control bending technology, so the permanent set that is produced and local draw ratio roller type cold bending, punching press or clod wash are rolling significantly reduce, so performance is more excellent.
Therefore 5) this utility model adopts trapezoidal corrugated web 2 to have higher fatigue resistance than flat web, can be applied in some to the higher specific area of member anti-fatigue performance requirement, as the large scale industry factory building etc.
This device can be used as the substitute products of traditional i iron and H shaped steel compound beam, and it is more extensive than i iron and H shaped steel compound beam purposes, the maximization that can realize member is used for special dimension and particular location, comprises the construction of large span industrial civil building and Longspan Bridge etc.
