Description
Technical field
The present invention relates to component technology field, thin walled steel structure house, particularly relate to a kind of Steel Thin-Wall top and back beam connection and syndeton.
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 in-flanges C-type steel and combination in-flanges C-type steel 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 in-flanges C-type steel 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 the large problem of in-flanges C-type steel manufacture difficulty in above-mentioned patented technology, can not combine with existing in-flanges C-type steel forming machine well, need shaping equipment, cost is high in input implementation process.In this patented technology, tubulose or channel-shaped in-flanges C-type steel are set in outside connector, recycling connector on hoop groove as slip-off preventing fixed center, with banding steel band by in-flanges C-type steel 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 in-flanges C-type steel is very thin, usually at about 0.3mm, be easy to breakage by the Steel Thin-Wall in-flanges C-type steel after the compressive strain of banding steel band, after breakage, cause in-flanges C-type steel intensity obviously to reduce, whole in-flanges C-type steel even can be caused to rupture, and preservative treatment cannot be carried out in the damaged rear cavity formed, 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.
Summary of the invention
The object of the invention is for existing thin walled steel structure connector and syndeton Problems existing and deficiency, a kind of Steel Thin-Wall top and back beam connection and syndeton are provided, excessive and the impaired problem of syndeton local compression power can be avoided, and different shaped steel connection requirement can be applicable to reduce difficulty of processing and to reduce cost of production.
Adopt following technical scheme for achieving the above object: a kind of Steel Thin-Wall top and back beam connection, comprise upper and lower binding face and forward and backward web, wherein, there is slanted angle in upper binding face and lower binding face; The both sides of upper and lower binding face arrange side respectively, there is slot to make way between forward and backward web and described side; The detent of punching press or punching is set on surface, the both sides of upper and lower binding face.
Have draw-in groove in the arranged outside of the dual-side of described upper and lower binding face, draw-in groove is arranged on the position corresponding with web.The lightening hole of coupling is provided with in the middle part of the left and right binding face of described top beam connecting component and forward and backward web.
A kind of Steel Thin-Wall top and back beam syndeton, comprise in-flanges C-type steel and top beam connecting component and banding steel band, described top beam connecting component comprises upper and lower binding face and forward and backward web, and wherein, upper binding face and lower binding face exist slanted angle; The both sides of upper and lower binding face arrange side respectively, there is slot to make way between forward and backward web and described side; The dual-side of described in-flanges C-type steel is inwardly provided with in-flanges; Upper in-flanges C-type steel and lower in-flanges C-type steel are set in outside the upper and lower binding face of described top beam connecting component, and in-flanges coupling is set in slot to make way; Arrange the detent of punching press or punching on surface, the both sides of upper and lower binding face, arrange rear pressure slot on in-flanges C-type steel surface, rear pressure slot coupling is sleeved in the detent of described punching press or punching; Described upper in-flanges C-type steel and overlap intrinsic banding steel band between lower in-flanges C-type steel and top beam connecting component and compressed fixing.
Have draw-in groove in the arranged outside of the dual-side of described upper and lower binding face, draw-in groove is arranged on the position corresponding with web, and steel band compressing in-flanges C-type steel local dent enters in draw-in groove.
Beneficial effect: upper in-flanges C-type steel and lower in-flanges C-type steel make-up are fixed on and form Steel Thin-Wall top and back beam connection and syndeton outside top beam connecting component by the present invention, and form reinforcement type syndeton by banding steel band is fixing.Top beam connecting component wherein arranges web and resigning hole, mutually to fasten and together with being compressed in, reach inside and outside nesting effect with upper in-flanges C-type steel with the in-flanges of lower in-flanges C-type steel both sides.Simultaneously male-female face is set respectively between connector with in-flanges C-type steel and mutually nested together with, by fastener carry out compression fixing after, can not only make outer hanging hook together with in-flanges tight compression, and adjacent male-female face can be made also to be overlaped by compression, thus reach fixing also anti-slip effect.In-flanges C-type steel is standard steel section, has five kinds of model in-flanges C-type steel, to adapt to different structure requirement of strength according to dimensional standard.The present invention is simple and reasonable, there will not be local to be squeezed and damaging problem, can be reached the object of easy, efficient construction by banding steel band, do not need the processing steps such as welding or riveted joint, and bonding strength is high, not easily slippage.Be provided with the lightening hole of coupling in the middle part of the part web of connector, further can alleviate the deadweight of this connector, thus the deadweight in house can be alleviated.
