Description
Technical field
The utility model belongs to the architectural shape technical field, is specifically related to the anti-flexing web H of a kind of special type shaped steel.
Background technology
What generally adopt in similar field at present is hot rolling i iron, hot rolled H-shaped and welded H section steel.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 wing plates peace face web is welded together into H type cross section, be applicable to when the shaped steel specification can't meet the demands, but welded H section steel adopts the dihedral weld seam more, and the welding job amount is bigger.
Traditional i iron and H shaped steel steel using amount are big, and main cause is that the anti-flexion capabilities of web is lower, so need to improve web thickness.And welded H section steel is because the ratio of height to thickness of web is restricted, and its web thickness is general also thicker, causes steel using amount 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.
If adopt existing patented technology (ZL 200310106253.9), according to China's national situation and present working ability,, need main equipment if will produce large-scale component, device fabrication and product process that all cost is higher, and implement at present and have certain degree of difficulty.
In addition, have desired pure trapezoidal web in the patent, in process, must cause the local uneven pulling of steel plate, produce the sclerosis of overstrain and material, influence the product stress performance.Simultaneously,, must influence speed of welding and quality, occur weld defect and stress easily in the part and concentrate, can influence the product stress performance equally because the transition of web corner is not mild.
In sum, the extraordinary anti-flexing web H shaped steel of studying a kind of with low cost, superior performance, long service life is those skilled in the art's goal in research.
Summary of the invention
The purpose of this utility model is to provide the extraordinary anti-flexing web H shaped steel of a kind of with low cost, superior performance, long service life.
The extraordinary anti-flexing web H shaped steel that the utility model proposes, its section shape of the mouth as one speaks is made of central-web 2 and upper and lower edge of a wing disjunctor, and its structure is as shown in Figure 1.Wherein, top flange 1 is parallel with bottom flange 3, and vertically between top flange 1 and bottom flange 3, web 2 is the corrugated web that even or inhomogeneous periodicity repeats for the length direction of once-forming to web 2, and this ripple section is that arc chord angle is trapezoidal.
In the utility model, described trapezoidal ripple section is that circular arc is excessive.
In the utility model, be respectively the single face fillet weld between described web 2 and top flange 1, the bottom flange 3.
In the utility model, the trapezoidal employing numerical control bending of arc chord angle technology is made.
In the utility model, web 2 ripple density and height can change as requested, as shown in Figure 3 and Figure 4.
In the utility model, described ripple section is that the arc chord angle transition is trapezoidal.Circular arc excessively makes web 2, and the stress flow transmission is smooth herein, has avoided the complex stress condition of web 2.And web 2 ripple corners are arc transition, and the welding gun walking smoothly is easy to guarantee welding quality when making the welding of web and edge of a wing steel plate, avoids weld stress to concentrate.
The utility model has been optimized the section mechanical property of H shaped steel and welded H section steel 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.
Preparation technology of the present utility model is as follows: will be converted into the trapezoidal web of the arc chord angle of the even or inhomogeneous repetition of ripple with steel along its length, and adopt the single face 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 H shaped steel with the hot rolling i iron, and under the rigidity situation equal with bearing capacity, steel using amount saves about 40%～60%, saves about 30% than welded H section steel.
Compare with existing patent Ripple Sternum (ZL 200310106253.9), the utility model has substantial difference and advantageous feature in the following aspects: can will adopt the single face fillet weld between the web and the edge of a wing during production, so just reduce half welding capacity, and reduced welding residual stress and permanent set, reduce cost simultaneously.By adopting arc chord angle to avoid the existing technological deficiency of the trapezoidal web of existing patent, promptly avoided the weld defect of trapezoidal sharp corner and strain to concentrate on the one hand, can make the welding gun walking level and smooth on the other hand, guarantee welding quality, avoid weld stress to concentrate.Former patented product adopts single ripple size, and web thickness must be according to stressed maximum position bearing capacity control, and it is limited that web is optimized the space.And adopt the trapezoidal broken line of extraordinary numerical control bending fabrication techniques band arc chord angle, 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.
Adopt the numerical control bending technology can not resemble permanent set and the local elongation that causes face in the steel plate roller type cold bending, punching press or the clod wash rolling and forming technology, thereby for formed overstrain of the making of trapezoidal broken line and local elongation minimum.
This product can replace i iron and H shaped steel, and more extensive than i iron and H shaped steel purposes, can realize maximizing being used for special dimension and particular location, comprises the construction of Longspan Bridge and shipbuilding etc.
