[utility model content]
Technical problem to be solved in the utility model is to provide the linkage of a kind of Stability Analysis of Structures, scaffold that safety factor is high.
The utility model solves the problems of the technologies described above by the following technical solutions:
A kind of linkage of scaffold comprises vertical rod and is connected in cross bar in the vertical rod that described vertical rod is provided with the company's patch diskette that is used to connect cross bar, and the end of described cross bar is provided with plug-in unit;
The described patch diskette that connects is provided with jack, and this jack matches with described plug-in unit;
Described plug-in unit comprises that a plug, a pin buckle, follows closely flexible connection by one between described plug and described pin are buckled;
Described pin button is cuboid, and its middle part is provided with an elongated hole, and the center line of the center line of this elongated hole and this pin button is an angle, and the central point of this elongated hole overlaps with the central point of this pin button; Described axle nail is arranged in this elongated hole.
The external surface of described plug is arc surface, matches with the external surface of described vertical rod.
Advantage of the present utility model is: 1, simple structure, reasonable in design, each cross bar all is independently to be connected in the company's patch diskette that is located in the vertical rod, has avoided arbitrary cross bar in traditional scaffold to be connected with vertical rod occurring damaging and causes the damage that is connected of vertical rod and other cross bar.2, the patch diskette of scaffold and plug-in unit all are independently, convenient construction personnel quickly dismantled and replacing.3, vertical rod and cross bar are connected by connecting patch diskette, and the pin of the plug bottom setting by crossbar end is buckled wedging and fixed Stability Analysis of Structures, safety factor height again; Plug and company's patch diskette are complementary, and the cooperation of adding the movable spacer pin of plug lower end makes that the structure of scaffold is more stable.4, cost of production low (node steel using amount province, node accessory are difficult for losing), and the recyclable repeated use of each link.5, this linkage can bear straight up or downward load, and can bear certain bending moment, punching and moment of torsion, make scaffold form space structures support with better stability, be suitable for setting up civil engineering structure construction and the dual-purpose scaffold of fitment operation, can also be the adoptable linkage of a kind of multifunction scaffold as the bracing frame of template and other temporary platform supports etc.

[specific embodiment]
A kind of linkage of scaffold, please consult simultaneously illustrated in figures 1 and 2, be respectively before it connects be connected after structural representation.Comprise vertical rod 1 and be connected in cross bar 2 in the vertical rod 1, vertical rod 1 is provided with the company's patch diskette 3 that is used to connect cross bar 2, shown in Fig. 3 A and 3B, evenly is provided with four jacks 31 about before and after this connects on the patch diskette 3, can connect four cross bars 2.
The end of cross bar 2 is provided with plug-in unit 4, and this plug-in unit 4 matches with jack 31, and promptly plug-in unit 4 inserts in the jack 31.Shown in Fig. 4 A, Fig. 4 B, Fig. 4 C, plug-in unit 4 comprises that a plug 41, a pin buckle 42, follows closely 43 flexible connections by one between plug 41 and pin buckle 42.
The external surface 411 of plug 41 is arc surface, matches with the external surface of vertical rod 1.
The course of work: connect patch diskette 3 and be weldingly fixed in the vertical rod 1, connecting evenly distributes on the patch diskette 3 is provided with four rectangle jacks 31, be used for the grafting of crossbar end plug-in unit 4, plug-in unit 4 bottoms are provided with pin button 42, pin has been buckled elongated hole 421, the center line of the center line of elongated hole 421 and pin button 42 has angle, and the both sides entity part of elongated hole 421 is the big and little wedge shape of an end of an end.Connect patch diskette 3 and connect four cross bars 2 simultaneously, vertical rod 1 is with after cross bar 2 is connected, by the pin of cross bar plug 41 bottoms buckle 42 rotate into level after, knock pin button 42 with hammer and make pin button 42 do level to motion to the little extreme direction of elongated hole 421 upsides, thus wedging cross bar plug 41.
