There is a forked connection coupled column in the inside of concavo-convex U-steel in a kind of corner, including corner at least described in two has concavo-convex
There is the inclined-plane of concavo-convex U-steel in U-steel, each corner in the inner part, is fixed together by connecting rod, and the two ends of the connecting rod are hung down respectively
Direct-connected to be connected to inner sleeve plate, the symmetrical outside side of each inner sleeve plate is provided with otch respectively inwards, and be divided at inner sleeve plate edge by otch
Inner panel and outside plate two parts；The otch of two inner sleeve plates is orthogonal, and screw is provided with the inner panel and regulation spiral shell is installed
Bolt, the end face of regulating bolt butts up against the medial surface of outside plate.
When many drift angles have tongue and groove shaped steel combination, each connecting rod middle part is connected by bracing piece and is combined into one.
Inner sleeve plate positioned at gap connecting plate two ends is respectively rectangle inner sleeve plate, and two length sides of rectangle inner sleeve plate
To being mutually perpendicular to.Anti-reversing mechanism is provided with the regulating bolt.
The anti-reversing mechanism is to be hinged with cam in regulating bolt end, and cam is connected with cam handle；Or, it is described
Anti-reversing mechanism is to be fixed with vertical connecting rod in regulating bolt ending vertical, and vertical connecting rod end is hinged with locking swing rod.
There is the inclined-plane of concavo-convex U-steel in each corner in the inner part, is fixed together by connecting rod, the two ends difference of the connecting rod
Inner sleeve plate is vertically connected with, through hole is provided with inner sleeve plate, flat cap connecting bolt, the flat cap connection spiral shell are installed in through hole
Bolt includes screw rod and flat cap and nut, and the flat cap is located at the inner side of inner sleeve plate, while internally being set on the bottom surface of slideway
There is an interior flat hole, the aperture in interior flat Kong Yubian caps outline and interior flat hole is more than flat cap, and the one or both sides in interior flat hole are provided with
Block.Through hole on inner sleeve plate is circular hole or is flat hole.
Or, there is the inclined-plane of concavo-convex U-steel in each corner in the inner part, is fixed together by connecting rod, the two ends of the connecting rod
It is respectively perpendicular and is connected with inner sleeve plate, the symmetrical outside side of each inner sleeve plate is welded with shell fragment；The shell fragment direction of two inner sleeve plates is mutual
It is perpendicular, screw is provided with the inner sleeve plate and regulating bolt is installed, the end face of regulating bolt butts up against the inner side of shell fragment
Face.
The solution have the advantages that：
1st, the present invention has concavo-convex U-steel to form internal forked connection coupled column as connection main body using follow-on corner, profit
With the connecting rod with inner sleeve plate realize it is quick, be stably connected with, speed of application is fast, effect is good.There is the connection of concavo-convex U-steel in corner
In structure, its side is provided with a notch for depression of bending and molding, and width identical with notch direction is provided with inside notch
More than the inner races of the bending and molding of notch, such structure design can significantly lift the moment of inertia to degree, so as to be lifted
The bending resistance of the square tube, torsional strength.
2nd, corner has the tongue and groove steel section jointing structure can be bolted using connector, makes the stabilization of quality of connection
