Abstract
The utility model discloses portable H section. The H section comprises a top flange, a web and a bottom flange, wherein the web is vertically arranged between the top flange and the bottom flange; the section of the web is a periodically repeated zigzag ripple; and the ripple section of the web adopts acute angles for transition. The H section has the following beneficial effects: the H section can replace joist steel and traditional H sections; as compared with the joist steel and traditional H sections, the H section is firmer than, saves steel, has wider application, can realize large size and is used in the special fields and special places, including the fields of building of large-span bridges and shipbuilding; the mechanical property of the section of the H section is optimized by changing the shapes of the webs of the hot-rolled H section and welded H section; change of the shapes of the webs is realized by carrying out one-time forming, full-automatic welding, spraying rust preventing and the like on the webs; and in production, one-side fillet welding can be adopted between the web and the flanges, thus reducing the welding workload by 50%.
Description
Technical field
The utility model relates to a kind of lightweight H shaped steel, especially relates to a kind of stable H shaped steel of distinctive anti-flexing, belongs to the architectural shape technical field.
Background technology
H shaped steel is the more good economical section steel of a kind of section mechanical property that formed by the i shaped steel optimized development, and especially section is identical with English alphabet " H " and gain the name.The each point extension is even on the cross section during H rolling of sectional iron, internal stress is little, compares with common i iron, has the advantage that modulus of section is big, in light weight, save metal, can make building structure alleviate 30-40%; Parallel because of the outside in its leg again, the leg end is the right angle, and assembling combination becomes member, can practice thrift the welding job amount and reach 25%.It is big to be usually used in the requirement bearing capacity, the heavy construction of cross section good stability (like factory building, highrise building etc.), and bridge, boats and ships, handling machinery, Equipment Foundations, support, foundation pile etc.The economical rationality of H shaped steel cross sectional shape, mechanical property is also better, therefore also extensive use and industry, building, bridge, lifting appliance aspect.What H formed steel construction section bar generally adopted at present is hot rolling i iron, hot rolled H-shaped and welded H section steel; Traditional in addition i iron and H shaped steel steel using amount are bigger; Main cause is that the anti-flexion capabilities of web is lower, thus need to improve web thickness, and welded H section steel since the aspect ratio of web be restricted; Its web thickness is generally also thicker, causes steel using amount excessive; H shaped steel of the prior art in addition receives the restriction of technical condition, and web is necessary for module extender board, and ratio of height to thickness is less; In use, be prone to exist the phenomenon of web flexing, therefore when desired supporting capacity and rigidity greatly, when stability requirement is high; Traditional product just is difficult to guarantee, can only increase the stability of web through measures such as reinforcing rib are set, and has so not only increased a large amount of welding jobs; Also increase the consumption of steel, caused the waste of human and material resources.
The utility model content
To the deficiency that prior art exists, the utility model technical problem to be solved is that a kind of lightweight H shaped steel is provided; Solved and existed in the background technology: the suitable flexing of straight line web; When requiring supporting capacity, rigidity big, can not guarantee the problem of instructions for use, and need not increase the welding job amount, do not increase the use of steel; Just can satisfy product requiring the high and light requirement of stability, reduce manufacturing cost.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of lightweight H shaped steel comprises top flange, web and bottom flange, and its web is vertically between top flange and bottom flange; The section of said web is to be the zigzag ripple that periodically repeats, and the ripple section of web is that acute angle is excessive.
Optimize, above-mentioned lightweight H shaped steel, its top flange is parallel with the bottom flange.
Optimize, above-mentioned lightweight H shaped steel, its top flange and bottom flange are hollow rectangular structure.
Optimize above-mentioned lightweight H shaped steel, its web structure that is formed in one.
Optimize, above-mentioned lightweight H shaped steel adopts the single face welded corner joint to connect between its web and the edge of a wing.
Optimize, above-mentioned lightweight H shaped steel, the thickness of its said web is less than 3.2mm, and the thickness of top flange and bottom flange is less than 4.5mm.
The utility model can replace i iron and traditional H shaped steel; Compare i iron and traditional H shaped steel more firmly, save steel, purposes is also more extensive; Can realize maximizing is used for special dimension and particular location, comprises fields such as the construction that is applied to Longspan Bridge and shipbuilding; Solved and existed in the prior art: the suitable flexing of straight line web; When requiring supporting capacity, rigidity big; Can not guarantee the deficiency of instructions for use, and need not increase the welding job amount, do not increase the use of steel, just can satisfy product and require stable requirement when high; The utility model is optimized its cross section mechanical property through changing shape hot rolled H-shaped and the welded H section steel web, realizes through technologies such as the one-shot forming of web, full-automatic welding, rust prevention by applying liquid material processing; The utility model can reduce by 50% welding job amount with adopting the single face welded corner joint between the web and the edge of a wing aborning; Reduce welding residual stress and deflection, reduced construction costs; The overall weight of the utility model is very light, under the prerequisite that does not reduce structural strength, alleviates gross weight in the use, saves use cost; The section structure of web has been optimized the relation between section mechanical property and the product steel using amount to a greater extent, saves the about 20%-50% of steel using amount than traditional shaped steel; The utility model can be used in the multiple building types, has high bearing capacity, high strength, good stress performance, and good anti-fatigue performance and from the characteristics that heavy and light combines is very good structural shapes materials.
