Description

A kind of cone fastening formula steel pipe scaffold connector

Affiliated technical field

The utility model relates to a kind of connector of builing industry steel pipe scaffold, especially a kind of connector of cone fastening formula steel pipe scaffold.

Background technology

At present, the steel pipe scaffold that generally uses in the builing industry be fastener type steel pipe scaffold and recent years the bowl fastening type steel pipe scaffold from external introduction.The former structure layout characteristics is that vertical rod and cross bar side position are stacked, the disjoint cluster of axis, and latter's topology layout characteristics are that the opposed snapping of vertical rod and cross bar, axes intersect are positioned at same plane.Application number be 200620146992.X's " a kind of nut bayonet type steel pipe scaffold connector ", the topology layout characteristics are the nut snap close butt joint forms that are connected to of vertical rod and cross bar, axes intersect is positioned at same plane, form compact firmly, standardization and the big frame construction of supporting capacity.Its imperfection part is: one, its opening-closing type circular cone body of bolt assembly can be with the lower port and the vertical rod fastening of four transverse bar main bodys, but the gap that exists between the upper port of four transverse bar main bodys and the vertical rod (for passing the necessary reservation size of vertical rod) will influence and connect effect; Two, being connected of its four transverse bars main body and cross bar adopted reverse bolt type or the screw bayonet type of living, and still comes with some shortcomings on fastening effect, tight degree and the fitting operation; Three, its details to connectors such as scaffold floor pressure pin, two vertical rod, hexagon shelf, two bar bridging, wall connecting rod, snap close interfacing parts still has not most design.

Summary of the invention

In order to overcome the deficiency on the 200620146993.X steel pipe scaffold connector technical pattern, the utility model is done further perfect on the basis of its basic structure principle.The utility model adopts cone fastening formula structure, with reach vertical rod and cross bar more firm be connected effect.

The technical solution of the utility model is: one three folding double cone cover in the same way is set in the vertical through hole of connector main body, vertical rod is installed in it, female cone body in the cone of double cone set upper side and the through hole port engages, and the cone of lower end is that the circular cone body of bolt is furnished with the circular cone nut.As long as so the circular cone nut is tightened in topology layout, just the double cone cover moves axially, the cone of upper end is done the footpath simultaneously and is inwardly moved, and fills up preset clearance fastening vertical rod, the also fastening vertical rod of the circular cone body of bolt of lower end.The cone joint of connection and cross bar disjunctor on the horizontal termination of connector main body is furnished with the nut of being with the female cone body.So topology layout is as long as fastening nut is just pressed the joint of the no radial clearance of body characteristics work of cone, with the firmly fastening of horizontal termination of cross bar joint and main body.Also the double cone cover can be made the reverse double cone cover of two foldings, and set up a circular cone nut in the top, be double cone bolt cone fastening formula.

Connector about the scaffold floor pressure pin: adopt the connector of opening-closing type three-way shape, install in the optional position of leger on demand.

Connector about two vertical rods: on the basis of single vertical rod four transverse bar main bodys, increase a vertical through hole and associated components, the hanger that the horizontal diagonal brace of installation is used is set simultaneously.

The connector of using about the hexagon shelf: the horizontal termination by 60 °, 120 ° layouts is set.

Part in parallel about two bar bridgings: two snap close interfacing parts are got final product with the junction plate disjunctor.

Length adjustment about wall connecting rod: adopt the expansion link form.

The beneficial effects of the utility model are: because technical pattern further perfect, make the frame construction of this scaffold firmly compact more and make things convenient for fitting operation.
