Abstract
The utility model discloses a kind of hybrid fastener for connection node, comprise steel pipe column, the first joint steel pipe and the second joint steel pipe; The second described joint steel pipe is rigidly attached on the outer circle wall of steel pipe column; The outer circle wall of steel pipe column is connected with the first otic placode, an end of the first joint steel pipe is provided with the second otic placode, and the second described otic placode is hinged on the first otic placode.This node can realize being articulated and connected, and can realize again being rigidly connected.<u/>
Description
Technical field
The utility model relates to node structure, especially hybrid fastener for connection node.
Background technology
Node is the soul place of structural steel design, the quality of joint structure, has considerable influence to the stress performance of structure, construction technology, construction costs.Usual steel tubular structure adopts tubular joint.Be in the patent document of 2009.5.20, disclose a kind of filling stainless steel tube component-stainless steel tube welding connection node if China Patent No. be the 200810240329.X applying date is 2008.12.17 publication date, belong to tubular joint, to be connected on chord member by welding point by one or more web member and to form tubular joint, transmitted axial push-pull power and the moment of flexure of web member to chord member by welding point, this tubular joint is often between rigidity or semi-rigid performance, can not flexible rotating, in large span slant-pull structure system, due to the prestressed stretch-draw of drag-line, the distortion of fastener for connection place, local is large, cause the destruction of local welded K-joint of steel tubular weld seam, destroy whole node structure the most at last.But only adopt single hinged joint, when needs realize a steel pipe and another steel pipe is rigidly connected, then cannot meet the needs of building, therefore, invention one can realize being articulated and connected, and can realize again rigidly connected node structure and necessitate.
Summary of the invention
The purpose of this utility model is to provide a kind of hybrid fastener for connection node, and this node can realize being articulated and connected, and can realize again being rigidly connected.
For achieving the above object, hybrid fastener for connection node, comprises steel pipe column, the first joint steel pipe and the second joint steel pipe; The second described joint steel pipe is rigidly attached on the outer circle wall of steel pipe column; The outer circle wall of steel pipe column is connected with the first otic placode, an end of the first joint steel pipe is provided with the second otic placode, and the second described otic placode is hinged on the first otic placode.
Because the second joint steel pipe and steel pipe column are for being rigidly connected, first joint steel pipe realizes joining with the first otic placode on steel pipe column by the second otic placode and is connected, therefore, hybrid fastener for connection node of the present utility model can realize being articulated and connected, and can realize again being rigidly connected.Because the second otic placode is hinged on the first otic placode, when being subject to the prestressed stretch-draw of drag-line, the second otic placode can rotate to a stressed side greatly, make node uniform force, therefore, the distortion of local can not be caused large and local damage node structure at Nodes, the supporting capacity of node is large.
As improvement, being plugged in the first joint steel pipe of the second end part of lug plate axis be connected with the first joint steel pipe.Like this, the connection area of the second otic placode and the first joint steel pipe is large, and be not easy to produce stress and concentrate, therefore, the bonding strength of the second otic placode and the first joint steel pipe is high, is connected firmly, reliably.
As improvement, the joint steel pipe end being connected with the second otic placode is provided with sealing dividing plate.
As improvement, between sealing dividing plate and the second otic placode, be welded with stiffener.Stiffener is set, enhances the bonding strength of the second otic placode and the first joint steel pipe.
As improvement, in described steel pipe column, be provided with inner ring dividing plate.The inwall of inner ring dividing plate to steel pipe column has supporting role, prevents the stressed rear distortion that radial direction occurs of steel pipe column, improves the structural stability of steel pipe column.
As improvement, the first otic placode is provided with axis hole; Second otic placode is positioned at pin joint place and is provided with otic placode reinforcing ring, otic placode reinforcing ring is provided with pivot pin, and the first otic placode and the second otic placode are hinged by axis hole and pivot pin.Otic placode reinforcing ring is set, improves the intensity of the second otic placode at pin joint place.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
Hybrid fastener for connection node as shown in Figure 1, comprises steel pipe column 1, first joint steel pipe 7 and the second joint steel pipe 2.The outer circle wall of steel pipe column 1 is welded with on the first otic placode 3, first otic placode 3 and has axis hole.The other end being axially plugged with the second otic placode 4, second otic placode 4 in an end of the first joint steel pipe 7 is provided with pivot pin 8, and the first otic placode 3 and the second otic placode 4 are hinged by pivot pin 8 and axis hole; The first joint steel pipe 7 end winding support being connected with the second otic placode has sealing dividing plate 5, is welded with stiffener 6, to strengthen the bonding strength between the second otic placode 4 and the first joint steel pipe 7 between sealing dividing plate 5 and the second otic placode.Be provided with inner ring dividing plate 9 in described steel pipe column 1, the inwall of inner ring dividing plate 9 pairs of steel pipe columns has supporting role, prevents the stressed rear distortion that radial direction occurs of steel pipe column, improves the structural stability of steel pipe column.Second otic placode is positioned at outside pivot pin and is provided with otic placode reinforcing ring.Otic placode reinforcing ring is set, improves the intensity of the second otic placode at pin joint place.One end of the second joint steel pipe is welded on steel pipe column 1 outer circle wall.
Node structure of the present utility model, the first joint steel pipe and the second joint steel pipe and steel pipe column form two kinds of different joint forms, can realize being articulated and connected, can realize again being rigidly connected, and therefore, bring conveniently to construction.
