Abstract
The utility model belongs to a wave webplate H beam, which aims to solve the problems that a linear webplate is easy to buckle, the steel consumption is high, the welding amount is high and the like or hardening is generated and the stress concentration is caused because the local part of a purely trapezoid webplate is unevenly stretched in the background art. The technical scheme solving the technical problems has the main points that a top flange and a bottom flange are parallel; the webplate is arranged between the top flange and the bottom flange; and the length direction of the webplate is in a periodic repeated wave shape. The utility model can be applied to manufacturing the H beam and has the obvious advantages of high product performance, cost reduction and the like and is easy to realize standard production.
Description
Technical field: the utility model belongs to shaped steel, particularly a kind of wave web H shaped steel.
Background technique: the economical rationality of H shaped steel sectional shape, therefore mechanical property is better, is widely used in aspects such as industry, building, bridge, handling machinery, and that what adopt is hot rolled H-shaped, welded H section steel and hot rolling I-steel to this type of section bar is more at present.The hot rolling I-steel and the hot rolled H-shaped restriction that is subjected to various technical specifications of existing specification, web is necessary for module extender board, and ratio of height to thickness is less.Cripling does not take place in order to guarantee before the surrender in welded H section steel, and the web ratio of height to thickness can not be excessive, thus need be by the stability that measures such as stiffening rib strengthen web be set, and welded H section steel adopts the dihedral weld seam more, and welding capacity is big.Deficiencies such as in sum, common H shaped steel also exists as the easy flexing of web when stress form is relatively reasonable, and steel using amount was big when stability requirement was high, welding capacity is big.Also propose pure trapezoidal web in the prior art, its existing defective is: easily cause the local uneven pulling of steel plate in course of working, produce hardened material, also may produce the stress concentration phenomenon of part, influence the stress performance of product.
Summary of the invention: the purpose of this utility model is exactly the technological scheme that proposes a kind of wave web H shaped steel, and background technique exists to solve: the easy flexing of straight line web, deficiency such as steel using amount was big when stability requirement was high, welding capacity is big; The local uneven pulling of perhaps pure trapezoidal web produces sclerosis, and the problem that may cause stress to concentrate.Solving this technical problem the technological scheme that is adopted is: a kind of wave web H shaped steel, and top flange 1 is parallel with lower flange 3, and web 2 is between top flange 1 and lower flange 3, and web 2 is the waveform that periodically repeats along its length.Wherein, the ripple section of described web 2 is the wavy curve of standard, and its wavelength is 155mm, and crest is 40mm.Form the single face fillet weld between described web 2 and top flange 1, the lower flange 3.Described web 2 wave waveforms adopt the once-through of numerical control roll-in technology.
The beneficial effect that the utility model is had compared with the prior art is: owing to adopt technique scheme, the first, web adopts the corrugated form of wave can eliminate the unfavorable phenomenon of web cripling, also can eliminate simultaneously of the influence of the waveform of web to the reduction of edge of a wing intensity, can make power transmission evenly smooth by one-time formed Wave web sweeping style, get rid of the complex stress condition that web may bear.The second, be respectively the single face fillet weld between described web and top flange, the bottom wing, reduce the welding capacity of half, when reducing cost, saving man-hour, welding residual stress and residual deformation have been reduced in the lump, and when web and flange plate welding, the walking of welding gun longshore current line is level and smooth, makes welding quality more guaranteed, avoids weld stress to concentrate.Three, adopt the wave ripple handsome in appearance, acoustic efficiency is good.Four, according to test, the utility model is compared with H shaped steel with the hot rolling I-steel, and under the rigidity situation equal with bearing capacity, steel using amount saves about 40% ~ 60%, saves about 30% than welded H section steel.Five, the utility model can adopt full automatic welding connection technology and the production of professional positioning tool anchor clamps, can guarantee accurate positioning between web and two wing plates, and the seam track unanimity realizes standardization easily, and weld seam nothing attractive in appearance is splashed, and has welded product and need not shaping.Six, the selected web wavy curve of the utility model, its wavelength is 155mm, crest is 40mm, makes product and process equipment scientific matching to have guaranteed that product is more suitable for every technical requirements of H shaped steel aspect mechanical properties of materials.Seven, the sheet deformation smoothness that adopts professional numerical control roll-forming fabrication techniques to form, thereby for formed residual strain of the making of web ripple and local elongation minimum, also realized along the optimization of beam length direction, thereby can reach the double effects that improves bearing capacity and save steel.Therefore eight, corrugated web has 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.Nine, the utility model can replace I-steel and the H shaped steel of general industry in producing, and more extensive than I-steel and H shaped steel purposes, and can realize maximizing is used for the special dimension place, comprises the construction of longspan structure and shipbuilding etc.
Description of drawings: Fig. 1 is the utility model overall structure schematic representation.
Embodiment:
Embodiment 1, and with reference to figure 1, a kind of wave web H shaped steel, top flange 1 is parallel with lower flange 3, and web 2 is between top flange 1 and lower flange 3, and web 2 is the waveform that periodically repeats along its length.Wherein, the ripple section of described web 2 is the wavy curve of standard, and its wavelength is 155mm, and crest is 40mm.Form the single face fillet weld between described web 2 and top flange 1, the lower flange 3.Described web 2 wave waveforms adopt the once-through of numerical control roll-in technology.
