Description
Technical field
The invention belongs to the link technique field of clod wash light steel section bar, more particularly relate 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, anti-seismic performance is good, and type of attachment is various, can adapt to complex building moulding, less or without wet work, suitable batch production optimal design and modularized production, short construction period, house general layout flexible arrangement, building waste is few, component is reusable, the pollution of environment is more and more received to the concern of people close to the feature of zero grade, and is listed in the project optimization in bottom and middle-high building.
At present, to exploitation and the application of novel high-strength cold-rolled forming section especially thin-walled cold-rolled forming section, the new forward position in cold-rolled forming section field is become.But China is inadequate to the deep processing of product members at cold bending thin wall steel work, not yet reaches part widely, modularized production.Get used to adopting foreign forming technique, the structural system with independent intellectual property right developed is few, lacks independent brand.Along with developing rapidly of new countryside construction in recent years, the house demand of new structure is constantly increased, have also been changed traditional idea gradually, steel work house also comes in rural development gradually, existing steel work housing system structure comparison is heavy, construction period is long, cost is higher, be unfavorable for that it is applied, inventor applied for proposing a kind of novel steel work housing system in the utility model patent in thin walled steel structure monomer section bar and built-up sectional material and thin walled steel structure room thereof in last year, present patent application is exactly the problem of the Fast Installation in order to the above-mentioned patent of supporting solution.
The patented technology that Patent publication No CN102359191A provides " thin walled steel structure connector and syndeton thereof ", in this patented technology, have employed the scheme of being carried out rapid abutting joint between connector and Steel Thin-Wall section bar by banding steel band.The program is applicable to short-term fast module thin walled steel structure house, and reasonable in design, intensity is higher under fault-free conditions.But there is profile structure complexity, the problem that manufacture difficulty is large in above-mentioned patented technology, can not combine with existing profile-forming machine well, need shaping equipment, cost is high, and impact is applied in input implementation process.In this patented technology, tubulose or channel-shaped section bar are set in outside connector, recycling connector on hoop groove as slip-off preventing fixed center, with banding steel band by section bar enforce compression hoop groove in.But in actual use, due to marginal existence step and the seamed edge of hoop groove wing plates on two sides, and the thickness of Steel Thin-Wall section bar is very thin; light-gauge steel section thickness is usually at about 0.3mm; be easy to breakage by the Steel Thin-Wall section bar after the compressive strain of banding steel band, after breakage, cause section bar intensity obviously to reduce, whole section bar even can be caused to rupture; and preservative treatment cannot be carried out in the damaged rear cavity formed, and rainwater causes syndeton to be corroded problem after entering damaged gap.So above patented technology exists potential safety hazard in actual applications, need to be improved.
