In sum, existing panel point link technique can't be applied in the trussed construction with aerated film depression bar.Therefore, seek a kind of lightweight, portable, installation, convenient disassembly, safe and practical, the node that can effectively discharge Moment at End is very important.
Summary of the invention
The object of the invention provides a kind of lightweight, portable, and installation, convenient disassembly, safe and practical can effectively discharge the joint form of Moment at End, to satisfy the needs of the trussed construction with aerated film depression bar.
The present invention adopts following technical scheme in order to achieve the above object:
A kind of annular assembling type node that is applicable to aerated film depression bar trussed construction, it is characterized in that: it comprises ring node plate 1 and the connection otic placode 4 that is connected connecting aerated film depression bar 3, have node circular hole 7 and node center hole 8 on the ring node plate 1, connection otic placode 4, rope head 2 are connected with ring node plate 1 usefulness pin.
Described annular assembling type node, the hole heart of centre bore 8 is positioned on the center of circle of ring node plate 1, can pass for connecting rod 10, is used for the horizontal connection between each truss structure.
Described annular assembling type node, depression bar otic placode 4 passes through welding mutually with the connected mode employing of aerated film depression bar 3, and at depression bar otic placode 4 and aerated film depression bar 3 floor 5 is set.
Described annular assembling type node, depression bar otic placode 4 quantity that connect in the end of each aerated film depression bar 3 are 2.
Described annular assembling type node, the diameter of otic placode circular hole 6 and node circular hole 7 leave the friction space than the large 1mm of pin diameter that passes it, guarantee that simultaneously pin inserts smoothly.
Described annular assembling type node, the large 1mm of thickness of two depression bar otic placodes, the 4 gap ratio ring node plates 1 on aerated film depression bar 3 terminations leaves enough friction spaces, guarantees that ring node plate 1 inserts between two depression bar otic placodes 4 smoothly.
Described annular assembling type node, the otic placode circular hole 6 that connects 3 two depression bar otic placodes 4 that are connected with the aerated film depression bar are on same axis, and the mid point of axis is on the axis of aerated film depression bar 3, and the connection that guarantees Nodes can not make rod member eccentric and bring additional bending moment.
Described annular assembling type node, otic placode circular hole 6 are positioned on the center line of the bar 9 that intersects at ring node plate 1 center of circle.
The present invention can obtain following beneficial effect: node of the present invention has that simple structure, power transmission are clear, the characteristics of reasonable stress, can accomplish hingedly, and it is good that the supposition of computation model and structure actual loading situation meet; The job site is mounted with by pin each assembly to node, and assembly method is simple, and the dismounting of this kind node is also very convenient simultaneously.
