Abstract
The invention discloses a steel pipe scaffold connection socket which is an overall-hollow cross cone-shaped connection socket formed from a metal tubular blank by virtue of die extrusion processing. The center of the connection socket is an axial round hole matched with the outer diameter of a scaffold vertical rod; four axial square holes with the same size are communicated with the axial round hole and uniformly distributed around the axial round hole; two opposite side surfaces of each axial square hole are vertical planes parallel to each other; the far-end side surface, relatively away from the center of the connection socket, of each axial square hole is an inclined plane inclining toward the inner side from top to bottom; and the slope of the inclined plane is equal to that of the inclined plane of a wedge plug on a scaffold cross rod. In the steel pipe scaffold connection socket disclosed by the invention, the forming technology is simple, a small quantity of materials is used, the connection socket is light, and the production cost is low; the socket is good in toughness and rigidity and strong in bearing capacity; the socket is fixedly connected with the plug, the operation is simple and convenient, and the contact area is large; and the socket is in close fit, has less possibility of getting loose and is good in connection stability.
Description
Technical field
The present invention relates to building operations and use scaffold, be specifically related to a kind of steel pipe scaffold gang socket.
Background technology
The performance of steel pipe scaffold depends on the performance of vertical rod and cross bar link node to a great extent.The vertical rod of bolton type and cross bar node connector generally use in present building operations, and the problem that this kind vertical rod and cross bar node connector exist is: 1. the node connector is scattered, is prone to lose; 2. the rod member at node place is eccentric the connection, and therefore the frictionally transmitted load has reduced its load-carrying ability; 3. node connects the fixing operation trouble, and the quality of connection of node not only receives the influence of the quality of part own, also receives the influence of workman's operational quality simultaneously, and the node quality of connection is difficult to control.The slotting dish plug-in type vertical rod of prior art and cross bar link node; The plug that utilization is fixed on crossbar end and the cooperation of slotting dish on being fixed on vertical rod realize that vertical rod fixes with being connected of cross bar, efficiently solve the problem of the vertical rod and the existence of cross bar node connector of above-mentioned bolton type.But the slotting dish of prior art adopts casting to insert dish or dish is inserted in the steel plate punching press, and the toughness that dish is inserted in casting is little, fragility is arranged, poor-performing when being happened suddenly load; The steel plate punching press inserts in the disc molding process that waste of material is serious, and rigidity is also slightly inadequate, and simultaneously, casting inserts that dish and punching press insert that dish exists all that complex forming technology, manufacturing cost are high, plug coils with slotting that contact area is little, the problem of connective stability difference.
Summary of the invention
The objective of the invention is to the problems referred to above, provide that a kind of cost of production is low, easy to use, vertical rod and the good steel pipe scaffold gang socket of cross bar connective stability ability.
The technical scheme that realizes above-mentioned purpose is: a kind of steel pipe scaffold gang socket; It is to use the tubular blank of metal to be the gang socket of a hollow cross bullet through the integral body of mould extrusion process moulding; The center of this gang socket is the axial circular hole that matches with the scaffold upright rod external diameter; Be connected with this axial circular hole and be evenly distributed on this axial circular hole around four axial square holes that geomery is identical are arranged; Each axial square hole is surrounded by three sides; Two opposite flanks of each axial square hole are the perpendicular that is parallel to each other, and the distal side far away apart from the gang socket center of each axial square hole is the inclined-plane that from top to bottom tilts to the inside, and the inclined-plane gradient of the wedge shape plug on the gradient on this inclined-plane and the scaffold cross bar equates.
The angle of inclination of said distal side is 8 ° ~ 12 °.
The height of said gang socket is 28mm ~ 32mm; The pipe thickness of the tubular blank of employed metal is 4mm ~ 6mm.
The invention has the beneficial effects as follows:
1, use the tubular blank of metal through mould extrusion process moulding, moulding process is simple, has no waste of material, and cost of production is low.
2, socket and plug composition link node, and socket is fixed in the vertical rod, and plug is fixed on cross bar, and the part of forming link node is few, the problem that no connector is lost.
3, the used material of gang socket is few, in light weight, and the toughness of socket and rigid nature are good, and supporting capacity is strong.
4, utilize being fixedly connected of wedge shape plug and inclined-plane jack, it is easy to connect fixing operation, and plug and socket contact surface connect greatly, cooperates closely, is difficult for becoming flexible, and connective stability can be good.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Describe in conjunction with the accompanying drawing specific embodiments of the invention.
Like accompanying drawing; The gang socket of this steel pipe scaffold is to use the tubular blank of metal to be the gang socket of a hollow cross bullet through the integral body of mould extrusion modling; The center of this gang socket is the axial circular hole 1 that matches with the scaffold upright rod external diameter; Around this axial circular hole 1, be evenly distributed with four axial square holes 2 that are connected with this axial circular hole 1; The geomery of four axial square holes 2 is identical, and each axial square hole 2 is surrounded by three sides, the perpendicular of two opposite flanks 3 for being parallel to each other of each axial square hole 2; The distal side 4 far away apart from the gang socket center of each axial square hole 2 is the inclined-plane that from top to bottom tilts to the inside, and the inclined-plane gradient of the wedge shape plug on the gradient on this inclined-plane and the scaffold cross bar equates.
Among the present invention, the angle of inclination of described distal side 4 is 8 ° ~ 12 °, and preferred angle of inclination is 10 °.
Among the present invention, the height of described gang socket is 28mm ~ 32mm, highly is 30mm preferably; The pipe thickness of the tubular blank of employed metal is 4mm ~ 6mm, and preferred pipe thickness is 5mm.
Like accompanying drawing, the present invention is welded in the steel pipe scaffold vertical rod that matches with it and uses.
