Description
Technical field
The present invention relates to a kind of device that scaffold upright rod connects that is used for.
Background technology
In building trade scaffolds erecting construction, existing be used for that the interconnective connector of two rod members (vertical rod) is had connectors such as fastener type, bowl fastening type, the complex structure of its connector own, attended operation is loaded down with trivial details, and efficiency of construction is low.And can not effectively eliminate problem because of rod member processing unbalance stress when rod member that alignment error causes is connected.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, cost of manufacture is low, processing ease, efficiency of construction are high, good connecting effect be used for the device that scaffold upright rod connects.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of scaffold upright rod connector comprises that the connecting cylinder that the upper end connects firmly on upper pright stanchion reaches and the integrated installation portion of connecting cylinder, sees that from top to bottom installation portion is " U " shape cavity, suitable for reading big, following young, the big up and small down wedge shape laying of " U " shape cavity; In " U " shape cavity, wedge shape iron is set; Wedge shape iron upper end is provided with anti-shedding mechanism; Wedge shape iron lower inside is the arc contact surface that matches with following vertical rod external diameter, constitutes a pressure face to following vertical rod external diameter during connection, and the outside, wedge shape iron middle part is provided with a hemisphere jut; During connection, hemisphere jut falls and installation portion " U " shape cavity base kissing merges locked.
In the such scheme, the semicircle inboard of the relative installation portion of said connecting cylinder is provided with the twice arcuate friction surface.The formed radius r in said arcuate friction surface to connecting cylinder axle center is less than the connecting cylinder radius R, and upper and lower vertical rod radius equates with r.
On the arcuate friction surface below the upper pright stanchion lower end, have endless groove.The described wedge shape iron first half is up-small and down-big wedge structure on the side direction both sides.Said anti-shedding mechanism is to have pin hole near wedge shape iron upper end, and pin is housed in the hole.
Advantage of the present invention is, structure is ingenious, and component are few; Processing ease; Utilize wedge shape iron to move down, the inboard arc contact surface in its underpart is pressed to down vertical rod, and outside hemisphere jut and installation portion " U " shape cavity base kissing merges locked; Following vertical rod realizes that under wedge shape iron pressure face and the two arcuate friction surface actings in conjunction of connecting cylinder inwall three frictions of upper and lower vertical rod are connected, and can effectively eliminate the problem of unbalance stress when being connected because of the rod member that rod member is processed with alignment error causes.

Reference numeral among Fig. 1～Fig. 4: 1, connecting cylinder; 2, wedge shape iron; 3, upper pright stanchion; 4, vertical rod down; 5, installation portion; 6, arcuate friction surface; 7, endless groove; 8, pin hole.
The specific embodiment
Like Fig. 1, shown in Figure 2; A kind of scaffold upright rod connector comprises that the connecting cylinder 1 that the upper end is welded on the upper pright stanchion 3 reaches and the integrated installation portion 5 of connecting cylinder, sees from top to bottom; Installation portion 5 is " U " shape cavity; " U " shape cavity suitable for reading big, following young laid with connecting cylinder 1 big up and small down wedge shape.The semicircle inboard of connecting cylinder 1 relative installation portion is provided with the arcuate friction surface 6 that twice are symmetrical in symmetrical center line p, and upper and lower vertical rod 3,4 radiuses equate that with the formed radius r in arcuate friction surface to connecting cylinder axle center r is less than the connecting cylinder radius R.On the arcuate friction surface below the upper pright stanchion lower end, have endless groove 7, can effectively avoid down the vertical rod upper end, guarantee that vertical rod contacts with the effective of arcuate friction surface down because of the distortion of ends such as the end burr that cause in the use or crimping.
Like Fig. 3, shown in Figure 4; In connector installation portion 5 " U " shape cavity, wedge shape iron 2 is set; The wedge shape iron first half is up-small and down-big wedge-shaped design (Fig. 3) on the side direction both sides; When wedge shape iron was in Fig. 4 position, the tapering through wedge shape iron can self be fixed on highest order with wedge shape iron, and install convenient next time.The arc contact surface of wedge shape iron lower inside for matching with following vertical rod external diameter constitutes during connection a pressure face of vertical rod external diameter down, and this pressure face and two arcuate friction surface 6 realize that to vertical rod down three rub to fix.The outside, wedge shape iron middle part is provided with a hemisphere jut, and during connection, hemisphere jut falls and installation portion " U " shape cavity base kissing merges locked.Wedge shape iron upper end can simply be provided with solder joint, just can prevent that wedge shape iron 2 from deviating from from " U " shape cavity downwards; Also can have a pin hole 8, in the time of in wedge shape iron 2 places " U " shape cavity, load onto pin at this pin hole 8 and can prevent that wedge shape iron 2 from deviating from from " U " shape cavity downwards near wedge shape iron upper end.
Operating principle of the present invention is, leans on last periphery fixed slightly connector connecting cylinder 1 upper end and upper pright stanchion 3 bottoms, in installation portion 5 " U " the shape cavity wedge shape iron 2 is set in advance; And load onto pin at pin hole 8, and will descend vertical rod 4 upper ends to insert connecting cylinder 1, upper and lower vertical rod two ends are contacted; Downward hammering wedge shape iron 2 upper ends; Wedge shape iron moves down, and the inboard arc contact surface in its underpart is pressed to down vertical rod, and outside hemisphere jut and installation portion " U " shape cavity base kissing merges locked.Following vertical rod 4 realizes that under wedge shape iron pressure face and 6 actings in conjunction of connecting cylinder 1 inwall two arcuate friction surface upper and lower vertical rod face friction is connected, and wedge shape iron 2 downward pressures are big more, and the connection power that rubs is big more.
During dismounting, hammering wedge shape iron bottom upwards, rubbing surface pressure disappears, and wedge shape iron the gap occurs with following vertical rod, and connector can be removed from descending vertical rod.
