Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

The scaffold is generally made of steel, iron as a reactive metal is easy to react with oxygen in the air to generate ferric oxide or ferroferric oxide, the two substances are commonly called rust, the rust is a loose and fluffy structure, once the rust is generated on the surface of iron, the internal iron still reacts with the oxygen, so that the iron is especially required to be rustproof, the scaffold is used outdoors and is easy to generate rust in a wind-blowing and sun-drying environment, the scaffold made of an aluminum alloy material is a high-quality choice, the chemical property of aluminum is more active than that of iron, but aluminum oxide is generated after the reaction of the aluminum and the oxygen, the aluminum oxide is a compact and compact material, and once the aluminum oxide is formed on the surface of the aluminum, the oxygen is blocked from entering the interior, so that the purpose of preventing rust can be realized.

However, although the hardness of the aluminum material itself is greatly different from that of iron, this can be improved by adding other metals to the aluminum alloy. The melting point of aluminium is about 660 degrees centigrade, and the melting point of iron is about 1500 degrees centigrade, though do not have difference in daily use, but when the scaffold frame shaping, especially in the welding process, the aluminium of low melting very easily produces the crater, the production reason of crater mainly needs the electric arc of igniting during the welding, when igniting electric arc, the high temperature in the twinkling of an eye that produces can make the surface of the aluminium material that contacts with the welding rod take place to melt, produce the crater promptly, if do not solve this problem, can lead to the partial position of aluminum product too thin, cause the potential safety hazard.

Referring to the attached drawings 1-5, the 368-degree welded vertical rod of the aluminum alloy scaffold in the embodiment includes a vertical rod 1 and a connecting plate 2, a connecting hole 3 is formed in the center of the connecting plate 2, the connecting hole 3 is a circular through hole, the connecting hole 3 can only allow the vertical rod 1 to pass through, the surfaces of the connecting plate 2 and the vertical rod 1 in contact are connected in a welding mode, a welding spot 4 is welded to the edge of the connecting hole 3 of the connecting plate 2 and the surface of the vertical rod 1, and the welding spot 4 is continuously arranged around the surface of the vertical rod 1 and is circular.

The angle around which the weld spot 4 forms a circle is more than 360 degrees and at the same time less than 375 degrees. Because can produce high temperature in the twinkling of an eye with aluminum alloy material direct contact when just starting to ignite electric arc, easily make the aluminum alloy melt and produce the crater, if carry out the welding of a mend crater after the welding is accomplished, be greater than 360 degrees welding promptly, can guarantee not to have the appearance of crater, if exceed 15 degrees mend the crater and can lead to the excessive thickness of double-deck solder joint 4. The optimum angle around which the spot weld 4 forms a circle is 368 degrees. The design tester of the 8-degree arc compensation pit can select the arc compensation pit exactly in the test process without causing the problem of over-thickness of the double-layer welding point 4, but the 8-degree angle is not well controlled, so the range is expanded to 15 degrees.

The vertical rod 1 is a hollow pipe, the connecting discs 2 on the vertical rod 1 are arranged in at least two, the at least two connecting discs 2 are arranged in parallel, and when the number of the connecting discs 2 is more than two, the distance between the connecting discs should be kept the same. When a plurality of connection pads 2 are designed to ensure that the vertical rods 1 are connected with the transverse rods, a plurality of transverse rods are connected simultaneously.

The connecting disc 2 is evenly provided with a plurality of special-shaped through holes 5 which are positioned between the connecting hole 3 of the connecting disc 2 and the outer edge. The purpose of setting up a plurality of heterotypic through-holes 5 is mainly to improve the connection between montant 1 and the horizontal pole, heterotypic through-hole 5 can regard as and the horizontal pole between the link of being connected, the design of heterotypic through-hole 5 also can reduce the use of aluminum alloy ex-trusions in addition, weight reduction makes things convenient for subsequent dismouting.

The design of welding more than 360 degrees is the key for realizing filling the arc crater, so that the uniformity of the surface thickness of the aluminum alloy is ensured, or the welded part is slightly larger than the thickness of the aluminum alloy, and the potential safety hazard problem caused by the fact that the aluminum alloy material is too thin due to welding is avoided.

Referring to fig. 4 and 5, the shape of the ring formed by the weld spots 4 of greater than 360 degrees is known.

For the special description of circles larger than 360 degrees mentioned in the above paragraph, perhaps some people may consider a circle as a maximum of 360 degrees, and describing a circle with more than 360 degrees is not very accurate, even if mathematically, a circle of 360 degrees and a circle larger than 360 degrees at the same radius are the same figure, which of course seems mathematically. However, circles greater than 360 degrees are also of practical significance, for example in this case, a design greater than 360 degrees is just filling the crater that is created when the arc is just initiated.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered in the protection scope of the present invention.
