Abstract
The present invention relates to a socket type linking node for cold-formed steel components, which has the moulding processes: in two connected plates, a hole is prefabricated on a lower plate, the cross section of the junction position of an upper plate, which corresponds to the prefabricated hole of the lower plate, is punched into a multiple-tooth ring by a punching machine, and the diameter of the multiple-tooth ring is equal to the hole diameter or the side length subtracting the double thickness of the upper plate; the multiple-tooth ring is inserted into the prefabricated hole of the lower plate; a connecting tool which is composed of an external expansible sleeve barrel and an internal pulling rod passes through the hole, the internal pulling rod is pulled out towards the direction which is reverse to the insertion direction by hydraulic pressure, and the pulling rod exerts pressure to the sleeve barrel to cause the sleeve barrel opening to expand, so that the sleeve barrel opening is butted with the multiple-tooth ring; the pulling rod continually exerts pressure to the sleeve barrel to cause the multiple-tooth ring to bend and to clamp tightly the circumference of the hole of the lower plate to form connection. The present invention utilizes the characteristics of cold-formed steel, such as thin wall, high intensity and diversified section modes to the maximum extent, and uses parent metal to form connection, which is material-saving and can not damage the protective layer of a material surface. The present invention has convenient and quick connection to improve work efficiency.
Description
Technical field
What the present invention relates to is that a kind of novel punching press Connecting format that is used for the cold formed steel structure---the making method of cold-formed steel member socket type connected node belongs to the cold formed steel technical field of structures.
Background technique
The stress performance of cold-formed steel member is different from the plain carbon steel construction element, the Placement that is used for the plain carbon steel structure as bolt connect that to be connected with rivet might not be the most rational connection pattern of cold-formed steel member.At present the pattern commonly used that connects of cold formed steel remains that bolt connects, is welded to connect, screw connects to follow closely with cold riveting and be connected.Situation about being applied in the cold-formed steel member at these connections in " Technical code for design of coldformed thin wall steel structures " has been made corresponding modify to the design clause, but still can't the most reasonably utilize the unique advantage of cold formed steel.Research socket type connected node is arranged, but it has very big use narrow limitation abroad, particularly it can't adapt to China's Lightweight Steel Construction present situation, is not suitable for China's cold formed steel sheet material commonly used and the connection of section bar.
Summary of the invention
The objective of the invention is to be applied to the irrationality of cold-formed steel member in connecting at traditional Placement, propose a kind of adaptation China Lightweight Steel Construction present situation, be applicable to novel punching press Connecting format---the socket type connected node that cold formed steel sheet material that China is commonly used and section bar connect fully.Technical solution of the present invention: the making method of cold-formed steel member socket type connected node: (one) is in two plates that connect, the prefabricated hole of lower plywood, top plate utilizes punch press to be die-cut into Polydentate ring with cross section, the corresponding joint of the prefabricated hole of lower plywood, the diameter of this Polydentate ring equals the diameter of hole or the thickness of the plate that the length of side deducts twice, and described Polydentate ring is circular Polydentate ring or rectangle Polydentate ring; (2) this Polydentate ring is inserted in the prefabricated hole of lower plywood; (3) fastening means that will be made of the sleeve and the inner dead man of outer expandable passes hole, utilize hydraulic coupling with inner dead man towards oppositely extracting with direction of insertion, dead man is exerted pressure to sleeve and is made the sleeve-port expansion prop up Polydentate ring; (4) the aperture circumference that continues to exert pressure and cause the Polydentate ring bending and tighten lower plywood connects thereby form.Advantage of the present invention: more traditional Placement; the socket type interconnection technique has been brought into play cold formed steel thin-walled, high strength, the diversified characteristics of section form to the full extent; utilizing mother metal to form connects; effectively save material and can not damage the material surface protective layer; easy to connect, quick, can effectively improve efficiency of construction.The socket type interconnection technique is intended to develop full-automatic, the incorporate production procedure of a cover---band or coiled material directly are made into the various lightweight steel frame assemblies of actual demand, as keel wall board or roofing truss etc.Complete production system is predetermined with the preassembly of implementation framework assembly and size, and makes framework wallboard or truss not use mould and not have under the condition of further measure and realize real-time assembling.
