Two ends of a first steel tube are respectively provided with a steel tube connecting piece, a draw bar is arranged in each steel tube connecting piece, and a limiting platform protruding outward is arranged on the front portion of each draw bar. Each limiting platform of each draw bar penetrates through an annular blocking plate arranged at the front end of each steel tube connecting piece to be arranged in the first steel tube, an annular pulling hole is arranged on each draw bar in front of each limiting platform, and the rear portion of each draw bar penetrates through a sliding friction piece. Contacting surfaces of the sliding friction piece and the steel tube connecting pieces are in the shape of matched inclined planes, the sliding friction piece and the steel tube connecting pieces form a cylinder, the first steel tube is provided with a pin in clamping mode, the pin penetrates through the annular pulling hole to be fixed under the first steel tube. The steel tube scaffold connecting piece is reasonable in structure, convenient to operate, firm in steel tube connection, safe and reliable and effectively resolves the problems of large labor intensity, low construction efficiency and material waste. Moreover, the pin is not easy to fall and lose.
Description
Technical field
The utility model relates to a kind of steel pipe scaffold connector.
Background technology
The conventional steel scaffold mainly adopts inverted bowl type scaffold and fastener type scaffold, and these two kinds of scaffolding structures are complicated, install and remove more loaded down with trivial details; Repeat usage is low, and the node steel using amount is big, and the node accessory is lost easily; Construction speed is slow, and labor strength is big, is not easy to transportation; And caused vertical rod and being connected of other cross bar to be affected because of destroying part cross bar and being connected of vertical rod sometimes, lack convenience and security and stability.
Summary of the invention
To above-mentioned situation, for overcoming the prior art defective, the purpose of the utility model just provides a kind of steel pipe scaffold connector; It is loaded down with trivial details effectively to solve the scaffold mounting or dismounting; Repeat usage is low, and the node steel using amount is big, accessory is prone to lose, and labour intensity reaches the problem of security and stability difference greatly.
The technical scheme that the utility model solves is; The first steel pipe two ends have connector of steel tube respectively, and there is stayed pole connector of steel tube inside, the limiting stand of oriented outer lug on the front portion of stayed pole; The ring baffle that the limiting stand of stayed pole passes in the connector of steel tube front end places in first steel pipe; There is annular pulling eye in the place ahead of limiting stand on stayed pole, the sliding friction part is passed at the rear portion of stayed pole, and the contact surface of sliding friction part and connector of steel tube is the inclined plane shape that matches; Constitute cylinder, be installed with on first steel pipe and pass annular pulling eye and be fixed on the pin below first steel pipe.
The utility model is rational in infrastructure, easy to operate, steel pipe is connected firmly, safe and reliable and pin difficult drop-off is lost, and efficiently solves that labour intensity is big, efficiency of construction is low, the problem of waste material.

The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Provided by Fig. 1-Fig. 5, the structure of the utility model is that first steel pipe, 1 two ends have connector of steel tube 2 respectively; There is stayed pole 3 connector of steel tube inside; The ring baffle 9 that the limiting stand 10 of oriented outer lug on the front portion of stayed pole 3, the limiting stand of stayed pole 3 pass in the connector of steel tube front end places in first steel pipe, and there is annular pulling eye 4 in the place ahead of limiting stand 10 on stayed pole; Sliding friction part 5 is passed at the rear portion of stayed pole 3; The contact surface of sliding friction part and connector of steel tube is the inclined plane shape that matches, and constitutes cylinder, is installed with on first steel pipe 1 to pass annular pulling eye 4 and be fixed on the pin 7 below first steel pipe.
Described first steel pipe 1 top with below the last tractive string hole that is interconnected 6 and following tractive string hole 11 are arranged; Last tractive string hole 6 is corresponding with the annular pulling eye 4 on the stayed pole with following tractive string hole 11; Last tractive string hole 6 is greater than annular pulling eye 4, and annular pulling eye is greater than following tractive string hole 11; Described pin 7 is up big and down small wedge shape, and the top of pin is taper, and the bottom is threaded oblateness; Described pin 7 inserts to go up in tractive string hole 6, annular pulling eye and the following tractive string hole 11 and is anchored on first steel pipe through first bolt 8.
By direction shown in Figure 1; Be set with second steel pipe 12 on the described cylinder, along with the insertion of pin 7, stayed pole 3 pulling sliding friction parts 5; Sliding friction part 5 is along connector of steel tube 2 bevel direction slippages; Can slippage 4-5mm, sliding friction part 5 and second steel pipe 12 produces sliding frictions and frictional force increases gradually links together connector of steel tube 2 and first steel pipe 1, second steel pipe 12; Described sliding friction part 5 is anchored at together with stayed pole 3 through second bolt 13; The diameter of described limiting stand 10 is greater than the interior diameter of ring baffle 9, and the interior diameter of ring baffle 9 is greater than the diameter of stayed pole 3; The two ends that described connector of steel tube 2 is a hollow are bevelled cylindrical; Described sliding friction part 5 is the tilted conical of hollow.
First steel pipe of the utility model links together through the sliding friction part and second steel pipe; Rational in infrastructure, easy to operate, steel pipe is connected firmly, safe and reliable and the pin difficult drop-off lose; The bolt fastener installation that efficiently solves traditional fastener type steel pipe scaffold is wasted time and energy, and labour intensity is big, is prone to lose; Corrosion is serious, and life cycle is short, efficiency of construction is low, the problem of the influence of the own quality of quality of connection fastener of waste material and fastener node and workman's operation.
