Several truss that link with joint, each truss comprises the first plate body, the second plate body and four vertical rods, four jiaos of ends of this first plate body or the second plate body link respectively the two ends of four vertical rods, and its first and second plate body is established respectively a centre bore, and the centre bore surrounding is provided with several perforating holes;

The number connection unit, it makes the first plate body of truss or the second plate body locate with the corresponding interface laminating of joint.

The interface of described joint is three, four or five.

The first plate body of the length and width of the interface of described joint and truss or the length and width of the second plate body are identical.

Described joint links most truss, forms a truss equipment that presents smooth outward appearance.

Described connection unit comprises a screw rod part, a C shape pad, a flat shim and a nut, the screw rod part enters joint inside through open space, sequentially wear and pass through C shape pad, flat shim, then wear the perforating hole that passes through joint and the perforating hole of the first plate body or the second plate body relative position, then screw togather with nut.

Truss device junction of the present utility model has following advantages:

1, the open space of joint of the present utility model, provide a hand of being combined with each truss for operation by human hand connection unit Locking joint to do space, and this open space makes the link operation of joint and each truss more convenient, has the joint design innovation of progressive.

2, the length and width of the first plate body of the length and width of the interface of joint of the present utility model and truss or the second plate body is identical, make to link by most truss the truss equipment formed and become smooth, attractive in appearance, it can improve the shortcoming of former times with the outstanding truss equipment of joint, the structure innovation of its joint and truss have that same category product is not thought and novelty.

3, the manufacture of joint of the present utility model and five interfaces simple and easy (need not connect joint with 12 web welding), its reduction in man-hour, cost of production reduce, and the open space of joint provides saving of the vertical instrument of user's operational group, it fills the joint design innovation that part meets industry applications.
