Abstract

The utility model relates to a safety steel pipe scaffold. The safety steel pipe scaffold is characterized in that a keyboard is fixedly connected on a vertical steel pipe, the keyboard is provided with four big-end-up wedged keys with wide exterior and narrow interior, stoppers are arranged on the lower portions of grooves on two sides of each key, key grooves matched with the keys are arranged on the heads of horizontal steel pipes, and recesses corresponding to the stoppers are arranged on the heads of the horizontal steel pipes perpendicular to the inserting direction. By match of the stoppers and the recesses, slippage caused by poor manufacturing precision of the keys and the key grooves is prevented, and the vertical positioning precision of the horizontal steel pipes is guaranteed unidirectionally.

Description

A kind of safe steel pipe scaffold

Technical field

The utility model relates to the building fittings field, particularly a kind of spigot-and-socket steel pipe scaffold that can improve safety.

Background technology

Application number is 200920269515.6, publication number is the Chinese patent " steel pipe scaffold that a kind of key of having set up ring-shaped sleeve connects " of 2015816320U, disclose and a kind ofly key directly has not been welded 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 feature of ring tube is, interior round foreign side, corner is by 1/4 circular cutting, the barrel thinnest part need be not less than 3.5 2 and be advisable, and ring tube peripheral pattern is concentric with interior hole circle, and four keys are pressed 90 degree and are separated by and are distributed in four planes and hit exactly, narrow outer wide in the key body, up-narrow and down-wide, the narrow outer wide gradient in lining plays not self-locking greater than the static friction angle, up-narrow and down-wide gradient is less than the static friction angle, play friction self-locking, during assembling, 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 weak point of this patented product is, the horizontal level of horizontal steel tube on vertical steel pipe is fully by the cooperate assurance of key with the keyway inclined-plane, when the accuracy of manufacture of key and keyway is not high enough, causes the horizontal steel tube position deviation excessive easily, even cause the landing of horizontal steel tube.

The utility model content

The purpose of this utility model is the defective that exists at background technology, and design provides a kind of safe steel pipe scaffold, and this scaffold can prevent the landing of horizontal steel tube.

In order to achieve the above object, the utility model is realized by following technological means:

A kind of safe steel pipe scaffold is characterized in that: a fixedly connected keyboard on vertical steel pipe, the key of the narrow chock shape of four low wide and up narrow and outer widths is set on the described keyboard, and in the grooves on two sides bottom of each key block is set; The keyway that matches with above-mentioned key in the setting of horizontal steel tube head, and perpendicular to the socket joint direction concave station corresponding with above-mentioned block is set at described horizontal steel tube head.

Further, described keyboard welding is fixed on the vertical steel pipe.

Further, described keyboard is affixed on the vertical steel pipe by bolt.

The utility model mainly has following good effect and technical characterictic:

By the mating reaction of described block and described concave station, prevented the landing phenomenon under the not high enough situation of key and the keyway accuracy of manufacture, and the unidirectional vertical positioning accuracy that has guaranteed horizontal steel tube.
