The utility model whose joint can be automatically locked has the advantages of rapid, convenient and flexible connection, high rigidity, stable and reliable stress, light weight, steel consumption saving, convenient manufacture and installation, and wide application. The utility model can be used after plugged and can be assembled into various types of brackets, space trusses, wire frames, derricks, pylons, beams, columns, rigid frames, platforms, housings, arches, guideway frames, etc. The utility model is a pipe type connecting device which is safe, convenient, rapid, economic, flexible and practical.

Description

Plugging type universal pipe joint

The utility model belongs to the realm of building construction, specifically a kind of building operations scaffold and bracing frame jointing.

In building operations, need various vertical, horizontal support structure and be used to provide construction operation platform, bracing frame, material hoisting frame, scaffold, elevator shaft etc.The various braced structuress of using have riveted type, welded type and bolt and nut interconnection system etc. at present, and it is the most general wherein to add junction plate bolt and nut interconnection system structure with angle steel.In the three dimensions braced structures, in the majority with netted ball node welding and bolt interconnection system.

The riveted type braced structures is used for permanent braced structures, and component and assembly precision are required height, assembling, maintenance, maintenance more complicated; The welded construction unit volume is big, makes, stores transportation and installing/dismounting trouble, and unsafe factor is many, the effort of taking a lot of work, and usually by lifting appliance.Space truss, when netted structure single-piece connects with bolt, the requirement on machining accuracy height, make complicated, the cost height, assembly and disassembly complexity, work efficiency are low, are unsuitable for often dismounting and the interim occasion that supports.

With angle steel and junction plate is that basic building block is simple with " universal rod body " processing and fabricating that bolt connects, assembly unit is flexible, in railway construction, use for many years especially building the worker system, but it is big that this kind rod member exists single-piece weight, connecting bolt quantity is big, the assembly and disassembly workload is big, speed is slow, and time-consuming effort is taken material, more than scattered, disadvantages such as overlapping investment is big, and the Tightening moment of each bolt requires tighter, and is restive in the practical operation, and the construction dependability is poor, safety is difficult to guarantee, thereby its application is subjected to certain limitation.

The purpose of this utility model is to provide a kind of compact conformation, and processing and fabricating is simple, and assembly and disassembly is quick and convenient, with material economize, use flexibly, cost is low, long-lived New-support jointing.

The technical solution of the utility model is: the omnipotent union of plug-in comprises universal contact, end cap, vertical rod joint, cross bar joint, brace joint.Universal contact comprises the elongated draw-in groove hole of a series of cylindricalitys that are parallel to each other or other shape, cross bar joint and brace joint termination match with it, and axially insert, vertical rod joint and end cap screw and lock at the universal contact two ends, thereby constitute the omnipotent union of plug-in.Vertical rod joint, cross bar joint and brace joint fasten as one with pipe respectively, constitute various forms and very little to the greatest extent plane, space frame with universal contact.

Owing to adopt such scheme, the utility model has the advantages that and connect fastening bolt, nut and the junction plate of having casted off once and for all, on universal contact, be provided with several cylindricalitys or other shape draw-in groove, cross bar brace joint can insert in its draw-in groove easily, end cap and vertical rod joint screw and lock at the universal contact two ends, and whole mounting or dismounting work is very quick, convenient, laborsaving.It is reliable to connect contact, and bending resistance, anti-twisting property are strong.

Below in conjunction with accompanying drawing, specifically describe embodiment of the present utility model.

1, cross bar 2, brace 3, universal contact 4, vertical rod 5, draw-in groove mouth 6, cross bar joint 7, vertical rod joint 8, threaded hole 9, vertical rod axis 10, draw-in groove hole 11, end cap 12, spiral boss 13, four cone central axis 14, universal contact contact 15, cross bar joint plug axis 16, cross bar center line 17, cross bar joint flat part plane 18, brace joint 19, the spiral slotted hole

The omnipotent union 14 of the utility model plug-in comprises universal contact 3, end cap 11, vertical rod joint 7, cross bar joint 6 and brace joint 18.Vertical rod joint 7 and vertical rod 4 fasten as one; Cross bar joint 6 and cross bar 1 fasten as one; Brace joint 18 and brace 2 fasten as one; Universal contact 3 also can fasten as one with vertical rod 4 as required.

Universal contact 3 is a cylinder, circumferentially arranges 1-8 elongated draw-in groove hole 10 on it arbitrarily.Draw-in groove hole 10 is cylindricality or other shape, and draw-in groove mouth 5 width are tabular less than the draw-in groove aperture, axially passes through in order to cross bar joint 6 and brace joint 18, cooperates with flat part plane 17 to contact.Universal contact 3 can be connected as a single entity 1-8 cross bar 1 and brace 3 like this.Fix at axial both direction in order to make cross bar joint 6 and brace joint 18, universal contact has threaded hole 8 and spiral slotted hole 19 in two ends about in the of 3, spiral boss 12 on end cap 11 and the vertical rod joint 7 inserts slotted hole 19 and it half-twist is locked, cross bar 1 and brace 2 not only lock, vertical rod 4 also fastens as one with universal contact 3, thereby constitutes universal contact contact 14.Cross bar joint plug axis 15 is 90 ° of angles with cross bar center line 16, the plug axis of brace joint 18 then with the brace axis can be any angle (90 °-α).

Universal contact 3, cross bar joint 6, vertical rod joint 7, end cap 11, the 18 equal moulding of brace joint, processing technology is very simple.According to working condition, the threaded hole 8 of universal contact 3 and vertical rod joint 7 can adopt thread connection with connecting also of 11 of end caps.

With the omnipotent union 14 of plug-in, can be assembled into the plane of different shapes such as triangle, quadrangle, pentagon, hexagon, octagon and space truss, rack braced structures very quickly and easily.To connect that rod member requires according to its purposes and supporting capacity can be that various tubing such as seam, seamless steel pipe formula aluminium alloys, plastics are arranged.
