Abstract
The utility model provides a connection structure for cross rods of a scaffold. The connection structure comprises a horizontal joint and a cross rod pipe fitting, wherein, the horizontal joint comprises a horizontal joint head and a horizontal joint body; a ring-shaped groove is formed at the connection part of the horizontal joint head and the horizontal joint body; the horizontal joint head adopts a progressive variable-diameter structure; the diameter of the horizontal joint head is the largest in the position of the ring-shaped groove; the head of the cross rod pipe fitting adopts a profiled caliber with an inclined plane, so as to be matched with the ring-shaped groove; the head of the cross rod pipe fitting enters the horizontal joint head by squeezing, so that the head of the crossrod pipe fitting is embedded in the ring-shaped groove at the connection part of the horizontal joint head and the horizontal joint body, the end part of the cross rod pipe fitting is matched with the ring-shaped groove, and axial restraining force is produced. Therefore, the utility model can prevent the horizontal joint head from being separated from the cross rod pipe fitting effectively.
Description
Technical field
The utility model relates to the bar connecting device that uses in a kind of device for building, the especially means for fastening scaffolding.
Background technology
All adopt more traditional fastening method at present both at home and abroad; it inserts horizontal joint in the corresponding steel pipe; behind the location; around interface, weld; in the use of scaffold the welding position through regular meeting be worn, collide or low temperature condition under use; cause the welding position sealing-off phenomenon to occur, it is not firm to cause cross bar to connect, and comes off or is shifted.
The utility model content
The purpose of this utility model is to overcome the above problems, and a kind of scaffold cross bar syndeton is provided, and it can prevent what horizontal joint from separating with cross bar.
A kind of scaffold cross bar syndeton of the utility model, its by: horizontal joint, cross bar pipe fitting are formed, it is characterized in that: horizontal joint is made up of horizontal joint head and horizontal joint body, there is an annular groove horizontal joint head and horizontal joint body junction, and its head adopts progressive variable-diameter structure to increase the footpath to the annular groove place; Cross bar pipe fitting head is an inclined-plane die mould bore, and the place cooperates with annular groove.
A kind of scaffold cross bar syndeton of the utility model: its cross bar pipe fitting head enters the horizontal joint head by extruding, in the annular groove that embeds horizontal joint head and body junction, can make the cross bar pipe fitting end cooperate with annular groove, produce axial constraint power, thereby effectively prevent separating of head and cross bar pipe fitting.
Figure of description
Fig. 1 looks sectional view for a kind of scaffold cross bar syndeton of the utility model master.
Among the figure, 1 is the horizontal joint head, and 2 is the horizontal joint body, and 3 is annular groove, and 4 is cross bar pipe fitting head.
The specific embodiment
A kind of scaffold cross bar syndeton of the utility model, its by: horizontal joint, cross bar pipe fitting are formed, it is characterized in that: horizontal joint is made up of horizontal joint head and horizontal joint body, there is an annular groove horizontal joint head and horizontal joint body junction, and its head adopts progressive variable-diameter structure to increase the footpath to the annular groove place; Cross bar pipe fitting head is an inclined-plane die mould bore, and the place cooperates with annular groove.Its cross bar pipe fitting head enters the horizontal joint head by extruding, in the annular groove that embeds horizontal joint head and body junction, it can make the cross bar pipe fitting end cooperate with annular groove, produces axial constraint power, thereby effectively prevents separating of head and cross bar pipe fitting.
