Description
Technical field
The utility model is related to a kind of connection system, more particularly to a kind of assembled connection of box-type section single-layer lattice shell is
System, belongs to field of steel structure.
Background technology
Box-type section bar is all kinds of thin-walled square tubes, rectangular tube or group weldering case being made with techniques such as clod wash, hot rolling and welding
The general name of type section rod member, with extremely excellent cross section property.In terms of mechanical property, have preferably unidirectional anti-than ring cross-section
Curved rigidity, has preferably axial torsional rigidity and weak axle bending rigidity than the open-type such as I-shaped, flute profile and Z-type section；From outer
See effect and see there is smaller unidirectional sight to block than ring cross-section, it is cleaner and tidier than open-type section；In terms of weather resistance, have
The same seal of ring cross-section, is easy to surface anticorrosion to handle and cleaning black dirt.In tall steel frame, large span space knot
All it is widely used in structure, storage rack structure and bridge structure etc., its material is generally mild steel, low-alloy steel or aluminium alloy
Deng.
Though box-type section bar excellent performance, node or interconnection technique development relatively lag behind, welding is relied primarily on, serious system
About its popularization and application and assembling development.The many associations with Node Development of existing assembling interconnection technique, often to sacrifice section box
Type section bar advantage exchanges easy for installation for, and versatility is not enough.For example, in large-span space structure, German POLO-1 is (specially
Sharp document 1) and China model cutting edge of a knife or a sword CP types (patent document 2) not only reduce axial torsional rigidity and weak axle bending rigidity advantage,
Appearance and weatherability also have certain loss；Mero BK (patent document 3), SEELE (patent document 4) and the China of Germany
Model cutting edge of a knife or a sword c-type (patent document 5) node assembling is then realized by the perforate of the rod member edge of a wing, weaken to a certain extent rod member carrying
Ability and sealing；Mero ZK (patent document 1), the Mero-1 (patent document 4) of Germany and OCTA-1 (the patent texts of Holland
Offer 3) node and then realize assembling dependent on the core cavity that crosses；The flat node in easypro Jiangxi (patent document 6) of China is then complicated because of connection,
Appearance and weatherability show slightly not enough, it is difficult to develop generalization.In addition, being said in terms of economy, German SEELE types
(patent document 4), OCTA-1 (patent document 3) type of Holland, the model cutting edge of a knife or a sword c-type (patent document 5) and easypro Jiangxi flat pattern (patent of China
Document 6) etc. node because complex process, the accuracy of manufacture require more than high or component etc. that reason causes cost higher, is also unfavorable for leading to
Promoted with changing.Finally, the connection between rod member is applied not only to the node of junction, is also commonly used in the middle part of component, turns round and corner,
And because each rod member functional characteristic is different, the rigidity of rod end connection transmission internal force also requires that difference, the company of association with Node Development
Connection technology difficulty in mechanical property has wide applicability.
In summary, the congenital of box-type section rod member is destroyed or weakened in various degree to existing assembled interconnection technique
Energy advantage, and versatility is not enough, portion of techniques economy is not good.The art of this patent scheme is directed to the present situation, has developed a kind of suitable
Novel fabricated for box-type section single-layer lattice shell connects system, and the Novel connection welding system not only maintains box-type section rod member
Appearance and weather resistance advantage, moreover it is possible to higher strong axle bending resistance, weak axle bending resistance and axial antitorque bearing capacity are provided.It is logical
The rationally design parameter such as high-strength bolt diameter and quantity, end plate thickness is crossed, this patent connection system can also realize relative broad range
Coupling stiffness is adjusted.Importantly, this patent connection system component is few, processing technology is simple, and error tolerance is strong, is manufactured into
This is low, can be widely popularized.
