In the scheme, the preferable structure is that the channel steel and the corrugated web plate are both made of cold-formed thin-wall steel with the thickness of 2mm-6 mm.
Preferred in this scheme, the wave height of ripple web equals the inslot net width of two channel-section steels about, and the ripple web can improve the support for two channel-section steels about, increases the bearing capacity.
Preferred in this scheme is, the laminating department of channel-section steel and ripple web and channel-section steel all connects with the connecting piece.
Preferably in this scheme, the connecting piece is self-tapping screw, need not to punch in advance.
Preferably, in this scheme, self tapping screw quantity and interval can be adjusted according to the building bearing capacity demand.
In the scheme, the channel steel and the corrugated web plate are preferably combined to form the box-shaped closed cross section, and the box-shaped cross section has great advantages in the aspects of stability and bearing capacity.
In this embodiment, the corrugated web preferably has various wave shapes with flat plate sections.
Compared with the existing section steel beam, the utility model has the beneficial effects that: the box-type beam is formed by connecting four channel steels and the corrugated web plates, compared with the common corrugated web plate beam, the box-type beam not only increases the bearing capacity and the integral stability of the beam, but also is connected by the self-tapping screws without considering the influence of residual stress generated by welding, and can be used as a wall (or a plate) after being modified.
