The specific embodiment
Below in conjunction with accompanying drawing 1 to Fig. 7 and embodiment, the utility model is described in further detail:
Wavelike steel webplate steel work freely-supported i beam, as shown in Figures 1 to 6, beam body comprises a Wavelike steel webplate 2, top flange steel plate 1, bottom flange steel plate 3, end socket end plate 4, described Wavelike steel webplate 2 is arranged between top flange steel plate 1 and bottom flange steel plate 3, top flange steel plate 1 is with Wavelike steel webplate 2 by being welded to connect, and Wavelike steel webplate 2 and bottom flange steel plate 3 are by being welded to connect.Wavelike steel webplate surface roughness is respectively 50 μ m, 80 μ m, 120 μ m, 160 μ m, 210 μ m, 310 μ m, 380 μ m, 420 μ m, 600 μ m, 820 μ m, 950 μ m, different roughness, different bonding strengths can be provided, roughness is larger, and Wavelike steel webplate 1 is stronger with the adhesion of concrete or coating.The thickness of Wavelike steel webplate is 2-100mm.The thickness of Wavelike steel webplate can be any one in 8mm, 13mm, 18mm, 23mm, 34mm, 41mm, 45mm, 50mm, 62mm, 76.1mm, 82.9mm, 96mm.
Top flange steel plate 1, bottom flange steel plate 3 surface roughnesses are 70-350 μ m.Increase top flange steel plate 1, bottom flange steel plate 3 surface roughnesses, high roughness can obviously increase the adhesive power of coating.
End socket end plate 4 and Wavelike steel webplate 2, top flange steel plate 1,3 welding of bottom flange steel plate.By end socket end plate 4 is set, improve the cross section rigidity of beam body and the intensity of link.
One end of freely-supported i beam is provided with plug 24, and the other end is provided with jack 25, between adjacent freely-supported i beam, by plug 24 and jack 25, is connected.By plug 24, coordinate with jack 25, form disjunctor and discontinuous structure, under can effectively prevent from overloading car and large load action or the phenomenon that drops of the beam body under geological process.
The thickness of top flange steel plate 1 is greater than the thickness of bottom flange steel plate 3.Because considering flexing in pressure zone, flexing need not be considered in tensile region, so traditional tensile region is identical with the steel using amount of pressure zone or section area, make tensile region part have the function phenomenon of having more than needed, it is science and uneconomic not, pressure zone steel using amount suitably increases, and is conducive to the pressurized of member, the function of tension part is given full play to, and reaches higher cost performance.When the thickness of top flange steel plate 1 is greater than the thickness of bottom flange steel plate 3, it is common i beam, and top flange steel plate 1 bears pressure.
