Abstract
The utility model relates to a steel billet hot rolling and continuous hot bending C-type steel, belonging to the metal roll forming. The utility model includes a C-type steel body, and is characterized in that the cross-section of the C-type steel body is a rectangle with an open slot: the ratio of the width to the length is 1 to 2 plus or minus 0.125. The incurve angle of the grasp is 67 degrees plus or minus 2 degrees. The utility model has the advantages of reasonable structure, low linear density, light in weight, high strength, convenient mating application, and is mainly suitable for the assembly of glass curtain wall.
Description
One, technical field:
The utility model relates to a kind of hot rolling of steel billet continous way hot bending C shaped steel, belongs to the roll forming of metal.
Two, background technology:
At present, the domestic existing curtain wall construction mostly is old-fashioned frame structure, is characterized in that metal wastage is big, Heavy Weight, and structure is cumbersome, install and use especially inconveniently, difficulty of construction is big, its more advanced wire rope structure arranged, be complex structure equally, be not easy to use, and the cost height.Along with the continuous development of China's building trade, and in order to improve building trade competitiveness in the international market, many building constructors introduce the external advanced curtain wall construction of exploitation one after another, and C shaped steel is exactly a kind of novel architecture shaped steel from external introduction.But, existing C shaped steel, its shape and structure are also unreasonable, and it is big to show as metal wastage in actual use, and structural strength is not high, its connection is also very poor, because it is dark that bolt sank to, string is moving excessive up and down, and not only bolt length is longer, and in use also increased some troubles, so its integrated cost is higher.
Three, summary of the invention:
The purpose of this utility model provides a kind of deficiency that has overcome above-mentioned prior art, structural strength height, the hot rolling of steel billet continous way hot bending C shaped steel that the metal use amount is few.
The purpose of this utility model is realized by following mode:
The utility model comprises C shaped steel steel body, it is characterized in that the cross section of C shaped steel steel body is the rectangle that has open slot, and its wide ratio with length is 1: 2 ± 0.125, and the inside corners degree of the interior curved grasp of its open slot both sides is 67 ° ± 2 °.
The utility model has the advantages that rational in infrastructurely, line density is little, in light weight, intensity is high, and it is dark in use to have avoided bolt to sink to, up and down the moving problem of string.
Four, description of drawings:
Fig. 1 is a cross-sectional view of the present utility model;
Fig. 2 is the cross section reference diagram of prior art;
Fig. 3 is the cross section reference diagram of user mode of the present utility model;
Fig. 4 is the cross section reference diagram of the user mode of prior art.
Five, the specific embodiment:
With reference to accompanying drawing 1, the utility model comprises C shaped steel steel body 1, steel body 1 adopts the moulding of continuous hot bending technology, the cross section of steel body 1 is the rectangle that has open slot, and the wide of its cross section is 25 ± 1mm, and length is 50 ± 1mm, wall thickness is 4 ± 0.5mm, the angle of the inside corners 3 of the interior curved grasp 2 of its open slot both sides is 67 ° ± 2 °, and the wall thickness of the end face of grasp 2 is 8 ± 0.5mm, and the area of entire cross section is 4.91cm
2, the line density of this C shaped steel steel body 1 is 3.85Kg/m, after testing, its intensity is better than similar prior art, and from accompanying drawing 3 as can be seen, its connection is also very good.What accompanying drawing 2 provided is a kind of cross section reference diagram of import C shaped steel, its profile is the rectangle that has open slot equally, the wide of it is 45mm, long is 66mm, its wide ratio with length is about 1: 147, and its wall thickness is 6mm, and the inside corners angle of the interior curved grasp of open slot both sides is 81 °, near the right angle, its cross-sectional area is 10.64cm
2, the line density of steel body is 8.35Kg/m.Although the metal use amount of the prior art is big, its structural strength is not high, and as can be seen, its bolt sinks to darker from accompanying drawing 4, make that bolt length is longer, and it is excessive to cause bolt to go here and there up and down, the problem of connection difference.
