Description
Technical field
The invention belongs to the interconnection technique field of clod wash light steel section bar, more particularly to a kind of thin-walled in-flanges c-type
Steel roof corner jointing and structure.
Background technology
Cold formed steel structure building system is because it is from heavy and light, and anti-seismic performance is good, and type of attachment is various, is suitable for multiple
Miscellaneous architectural image, less or without wet work, suitable batch production optimization design and modularized production, short construction period, house lattice
Office's flexible arrangement, building waste is few, and component is reusable, to the pollution of environment close to the characteristics of zero grade increasingly by people
Concern, and be listed in the project optimization in bottom and middle-high building.
At present, to the exploitation and application of novel high-strength cold-rolled forming section especially thin-walled cold-rolled forming section, as cold-rolled forming section neck
The new forward position in domain.However, China is inadequate to the deep processing of product members in cold bending thin wall steel construction, extensive part is not yet reached
Change, modularized production.Get used to using foreign forming technique, the structural system with independent intellectual property right developed lack again
It is few, lack independent brand.With developing rapidly for new countryside construction in recent years, the house demand to new structure constantly increases,
Traditional idea is gradually also changed, steel construction house also gradually comes in rural development, existing steel construction housing system knot
Structure is heavier, and construction period is long, and cost is higher, is unfavorable for its popularization and application, and inventor had applied for Steel Thin-Wall in last year
A kind of new steel construction is proposed in the utility model patent in structures alone section bar and built-up sectional material and its thin walled steel structure room
Housing system, the problem of present patent application is exactly for the Fast Installation of the supporting above-mentioned patent of solution.
Patent publication No CN102359191A provides the patent skill of " thin walled steel structure connector and its attachment structure "
Art, in the patented technology, employs the scheme for carrying out rapid abutting joint between connector and thin-walled steel profile by banding steel band.
The program is adapted to short-term fast module thin walled steel structure house, reasonable in design, and intensity is higher under fault-free conditions.So
And, to there is profile structure in above-mentioned patented technology complicated in input implementation process, the problem of manufacture difficulty is big, it is impossible to well with
Existing profile-forming machine is combined, it is necessary to which shaping equipment, cost height, influence popularization and application.In the patented technology, it will manage
Shape or channel-shaped section bar are set on the outside of connector, are recycled the hoop groove on connector as anti-dropout fixed center, are used banding steel
Band forces section bar to be compressed in hoop groove.But in actual use, due to bind round groove wing plates on two sides marginal existence step and
Seamed edge, and the thickness of thin-walled steel profile is very thin, light-gauge steel section thickness is tightened steel band compression generally in 0.3mm or so
Thin-walled steel profile afterwards is easy to breakage, causes section bar intensity substantially to reduce after breakage, or even whole section bar can be caused to be broken, and
And the cavity formed after breakage can not carry out preservative treatment, rainwater causes attachment structure to be asked by corrosion after entering damaged gap
