Abstract
The utility model relates to a light H-section steel, which belongs to the technical field of materials for buildings. The light H-section steel of the utility model comprises two flange parts, a web plate part and a connecting part which is on the two flange parts, wherein the flange parts are hollow rectangular structures, the web plate part is two overlapped web plates, the two overlapped web plates of the web plate part are occluded through a punched hole, and the light H-section steel is formed through welding a whole galvanized board on the connecting part with high frequency and through being sprayed with zinc along. The utility model has the advantages of strong stability, lighter whole weight of a profile, low cost and long service life, the web plates in the middle are engaged through the punched hole, and the integrity of the profile is stronger, which not only further increases the stability of the profile, but also further lowers the weight of the materials.
Description
Technical field:
The utility model belongs to the construction timber technical field, is specifically related to a kind of light-duty H shaped steel.
Background technology:
Cold-rolled forming section is a main material of making light section steel structure, adopts steel plate or steel strip cold-bending moulding to make.Its wall thickness not only can make very thin, and has simplified production technology greatly, enhances productivity.Can produce the wall thickness that is difficult to produce with general hot-rolling method evenly but the various section bars of cross sectional shape complexity and the cold-rolled forming section of unlike material.Cold-rolled forming section also is widely used in the vehicle manufacturing except that being used for various building structure, aspects such as agricultural machinery manufacturing.The cold-rolled forming section kind is a lot, divides opening by the cross section, and semi-closed port is remained silent.By shape clod wash channel-section steel, angle steel, Z-shape steel, square tube, rectangular tube, shape tube are arranged, rolling door etc. are according to the GB6725-92 regulation, and cold-rolled forming section employing normal carbon structure is born, carbon constructional quality steel, and low-alloy structural steel steel plate or steel strip cold-bending are made.
H shaped steel is that a kind of section area distributes the rational more efficient section bar of economic section of optimization, the ratio of strength to weight more, because of its section and identical the gaining the name of English alphabet " H ".H shaped steel has that bending resistance is strong, construction is simple, save advantages such as cost and lightweight construction, extensively should.
H shaped steel is a kind of novel economizer construction steel.The economical rationality of H shaped steel cross sectional shape, mechanical property is good, and the each point extension is even on the cross section, 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 save welding, the riveting work amount reaches 25%.H shaped steel is mainly used in industrial premises, civilian construction, municipal engineering, oil platform, bridge, flat car crossbeam, the electric power support of electric railway, railway steel structure bridge along the line etc.Light-duty, microlight-type H shaped steel is highly suitable for container, mobile house, all kinds of garage, box train, electric support, all kinds of venue, villanette manufacturing industry.
H shaped steel generally is made up of wing plate and web at present, and the H shaped steel wing plate of selling on the market is the solid slab structure, so its characteristic is more single.
The utility model content:
At the H formed steel construction is single in the market, the shortcoming that characteristic is single discloses a kind of novel light-duty H shaped steel.
A kind of light-duty H shaped steel, comprise two edge of a wing portions, a web portion and a connecting portion, wherein two edge of a wing portions are hollow rectangle structure, and the rectangle limit of an edge of a wing portion in two edge of a wing portions is airtight, and the rectangle limit of another edge of a wing portion is by connecting portion (3) closure; Described web portion is two overlapping webs, and the edge of a wing can also be the open squares structure under the situation of needs, and this edge of a wing portion also can select shapes such as quadrangle, triangle, circle or ellipse for use according to architectural needs.
Above-mentioned light-duty H shaped steel, wherein described web portion are provided with 1-4 overlapping punching.
Above-mentioned light-duty H shaped steel is that a whole sheet material is stamped to form, and carries out high-frequency welding in an outer side edges of its hollow flange, forms H shaped steel overall structure.
The utlity model has following beneficial effect:
1, one-body molded by the cold roll forming technology, only form integral section by the ratio-frequency welding welding at seam crossing, reach the strong purpose of stability;
2, raw material use the following steel plate of 2.0MM, and the overall weight of section bar is lighter, alleviates gross weight in the use under the prerequisite that does not reduce structural strength, save use cost;
3, raw material all use galvanized steel plain sheet, use the free from corrosion consequence in back, prolong section bar application life;
4, Zhong Jian web makes the section bar globality stronger by the punching interlock, has not only further increased the stability of section bar, and makes the weight of material reduce once more.

1, Fig. 1 is the stereogram of the utility model one embodiment;
2, Fig. 2 is the cross-sectional view of Fig. 1;
3, Fig. 3 is the lateral view of Fig. 1.
The figure number explanation:
1, edge of a wing portion, 2, web portion, 3, connecting portion, 4, punching.
The specific embodiment:
Embodiment:
A kind of light-duty H shaped steel of the utility model, curve the rectangular teeth structure of reflection each other by a whole zinc-plated sheet material through curved cold forming technology, the corresponding site of the rectangular teeth structure of videoing is each other carried out pressing, forming the cross section is the structure of the overlapping web portion 2 of hollow rectangle structure edge of a wing portion 1 and two webs, the hollow rectangle limit of an edge of a wing portion in two edge of a wing portions 2 is airtight, the hollow rectangle limit of another edge of a wing portion is by going up through the high-frequency welding closure and following spray zinc and handle at connecting portion (3), dash three punchings 4 with punching machine in the same position of two webs then, two webs are by punching 4 interlocks, both alleviate the weight of H shape steel body, increased the stability of section bar again.
The utility model can fill as required to add such as sound insulation materials, heat-barrier material, reinforcement material in the edge of a wing of hollow rectangle structure in use and wait the different requirements that reach architectural.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any formal and substantial restriction, all those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when can utilizing the above technology contents that discloses, and a little change of making, modify the equivalent variations with differentiation, be equivalent embodiment of the present utility model; Simultaneously, all foundations essence technology of the present utility model all still belongs in the scope of the technical solution of the utility model change, modification and the differentiation etc. of any equivalent variations that above embodiment did.
