Abstract

The utility model discloses a steel tube scaffold. The steel tube scaffold comprises four key bodies and an annular sleeve; the shape of the key body has a narrow upper end and a wide lower end and a narrow inner end and a wide outer end, a cylinder body of the annular sleeve is as high as the key body, an inner hole is a round hole, and the aperture is slightly greater than the outer diameter of the steel tube, the thinnest part of the cylinder wall is 2-3 cm, the outer side is provided with key bases at intervals of 90 degrees, and a concave arched slot is arranged between the key bases; the four key bodies are respectively combined with the key bases on the annular sleeve through welding so as to form an integral keyboard, the keyboard is fixedly connected with the steel tube, the setting direction of the key body is in consistent with the connecting direction of the steel tub, and the middle part of outer side of each of the four key bodies is provided with a vertical groove. By setting the groove, the key body weight is reduced; the steel tube scaffold provided by the utility model has considerable dosage in the constructional engineering, thus saving cost, and being rational in design and suitable for popularization.

Description

A kind of steel pipe scaffold

Technical field

The utility model relates to the building fittings field, particularly relates to a kind of through the steel pipe scaffold that groove has alleviated the key body weight is set.

Background technology

Application number is 200920269515.6, publication number be 201581632U Chinese patent " steel pipe scaffold that a kind of key of having set up ring-shaped sleeve connects discloses and a kind ofly directly has not been welded in key on the vertical steel pipe; but with ring-shaped sleeve four keys keyboard that forms a whole, then keyboard is welded on the vertical steel pipe again, the characteristic of ring tube is; interior round foreign side, corner is by 1/4 circular cutting, the barrel thinnest part need be not less than 3.5mm and be advisable; ring tube peripheral pattern is concentric with interior hole circle, four keys are separated by by 90 degree and are distributed in center, four planes, and are wide outside narrow in the key body; that up-narrow and down-wide, gradient wide outside the lining is narrow plays not self-locking; up-narrow and down-wide gradient plays friction self-locking less than the static friction angle, during assembling greater than the static friction angle; Keyway in the mouth of pipe welding of horizontal steel tube, the horizontal steel tube socket joint that will have keyway is installed on the vertical steel pipe that has keyboard, has just formed the steel pipe scaffold that a kind of key of having set up ring-shaped sleeve connects.The product weak point of this patent is that the key body is too loose, causes the weight of key body own too heavy, and therefore waste of material under the situation of guaranteed strength, can alleviate the key body, can also practice thrift cost.

The utility model content

The purpose of the utility model is to overcome the problems referred to above that steel pipe scaffold exists in the prior art, proposes a kind of steel pipe scaffold.The utility model is provided with groove through employing and has alleviated the key body weight, because this utility model consumption in construction work is very big, thereby practices thrift cost, and is reasonable in design, is suitable for promoting.

The utility model adopts following technical scheme to realize:

A kind of steel pipe scaffold comprises four key bodies and ring-shaped sleeve, said key body be shaped as up-narrow and down-wide and in narrow outer wide; The cylindrical shell of said ring-shaped sleeve and key body are with high; Endoporus is a circular hole, and the aperture is slightly larger than the external diameter of steel pipe, it is characterized in that: the barrel thinnest part is 2-3cm; The outside is separated by by 90 degree and is provided with keyseat, is provided with the deep-slotted chip breaker of indent between the keyseat; Said four key bodies are combined into the keyboard of an integral body respectively through the keyseat of welding manner and ring-shaped sleeve; Said keyboard is fixedly connected with steel pipe; Said key body that direction is set is consistent with the closure of steel pipe, said four external middle side parts of key are provided with vertical groove.

Said groove section is " V " font, groove depth 9-10cm.

The mode of said fixed connection is for being threaded.

The utility model compared with prior art, its advantage is:

1, the utility model employing barrel thinnest part is 2-3cm, has certain rigidity to guarantee ring-shaped sleeve, and is not yielding; Deep-slotted chip breaker between the keyseat can play the effect that alleviates ring-shaped sleeve weight; The key body be shaped as up-narrow and down-wide and in narrow outer wide, played the effect of not self-locking; Adopt " V " font groove is set, groove depth 9-10cm has alleviated the key body weight, because this utility model consumption in construction work is very big, thereby practices thrift cost, and is reasonable in design, is suitable for promoting.

2, the utility model adopts and to be threaded to the connected mode between keyboard and the steel pipe, is threaded and can plays fixing effect equally, and rise very convenient to usely, and dismounting is also convenient.
