As an improvement, the wave height of the corrugated web upper and lower ends is respectively equal to clear span in the slot of two channel steels up and down, wave
The adjacent peaks or trough of line web are fitted closely with the two side walls in channel steel respectively.
As an improvement, the connector is tapping screw, self tapping self-drilling screw or nailing.
As an improvement, the waveform of the corrugated web is that trapezoidal ripple, sine bellows, rectangle ripple and arc chord angle are trapezoidal
Any one or a few in ripple combines.
As an improvement, the corrugated web is trapezoidal corrugated plating or the trapezoidal corrugated plating of arc chord angle, corrugated web and channel steel
The straight panel segment length of inner sidewall contact is not less than 20mm, and the tilt angle of tilted plate section is 30 ° ~ 90 °.
As an improvement, the corrugated web using roll-in or roller punching at.
As an improvement, the channel steel is clod wash equilateral channel steel.
Compared with prior art, the utility model has the beneficial effects that:
The utility model proposes a kind of light gauge cold-formed steel shape corrugated web combination beams, and it is light-duty to improve traditional cold bending thin wall
The stress performance of steel structure member, after comprehensive comparison, the utility model has the advantages that following.
The light gauge cold-formed steel shape corrugated web combination beam uses trapezoidal ripple or the trapezoidal corrugated steel of arc chord angle, and plate thickness is very
It is small but there is excellent out of plane stiffness and anti-flexing bearing capacity, it is antitorque, shearing resistance capability improving is obvious.With double limb splits
Work shape or box section are compared, and in the identical situation in section, can obtain bigger antitorque, shear-carrying capacity and resistance to deformation energy
Power, steel can also further be saved by being applied in cold bending thin wall light steel structure, have better economic benefit.
The light gauge cold-formed steel shape corrugated web combination beam is using tapping screw, self tapping self-drilling screw or nailing connection, nothing
It need to weld or punch, assembling process is simple pollution-free rapidly.Meanwhile this combination beam use clod wash equilateral channel steel, corrugated steel,
Tapping screw, self tapping self-drilling screw or nailing have current engineering regular size, on this basis, can attempt more new groups
Conjunction form reduces R&D and production cost without developing new production technology.
Therefore, using the light gauge cold-formed steel shape corrugated web combination in the utility model in cold bending thin wall light section steel structure
Beam can be improved construction efficiency and obtain good economic effect.The all components of the combination beam can be in factory normalization
Production, can be realized accurate split, and compared with similar product in current lightweight steel construction, the mechanical property of the combination beam is more excellent, uses
Steel amount is smaller, assembling is more convenient, the completely left out splicing operation of welding sequence or a large amount of rod pieces, in-site installation faster more ring
It protects.
