Disassembled and assembled light supporting shed rack

Abstract

The invention relates to a detachable light bracing trellis, which comprises at least two support bars and a plurality of cross bars and / or diagonal ties and / or cross holdfasts which are respectively connected between the two support bars, connecting positions between each cross bar or diagonal tie or cross holdfast and the support bar are respectively provided with a connecting structure which are detachably connected on the support bars. The invention adopts a connecting disc structure and a connecting fastener structure which can be assembled and disassembled between the support bars and the cross bar or the cross holdfast, and the firmness and reliability of the connecting are strengthened by the detachable connection of the connecting disc and the support bars, and the invention can effectively adopt light aluminum alloy sections, electron alloys sections, steel casting, aluminum pressure castings, and multiple tubes such as steel pipes, plastic-aluminum tubes and the like to make various monotowers or double towers or trellis which are adapt to various environments with high casualness and durability, and are not easy to bounded with foreign matters such as cement and the like, and are convenient for climbing stairs, walking stairs or platforms, and the monotowers or double towers or trellis are applicable to the employment of occasions with various heights.

Description

technical field [0001] The invention relates to a supporting device, in particular to a metal bracket or scaffold applicable to building construction or other fields. Background technique [0002] In the single or double towers or scaffolds made of metal materials used in building construction, interior and exterior wall decoration and maintenance, stage frame layout or exhibition shelves, and high-altitude operations of ball table frames, iron pipes are generally used as scaffolds. The basic components are to expand the height and width of the scaffold by sequentially connecting iron pipes of different lengths by welding. Obviously, for aluminum alloy profiles, magnesium alloy profiles, steel castings, It is obviously not feasible to adopt this method for composite pipes such as aluminum die-casting parts and plastic steel pipes and aluminum-plastic pipes. At the same time, in order to reduce the workload and labor intensity of on-site construction, the scaffolding using i...

Problems solved by technology

At the same time, in order to reduce the workload and labor intensity of on-site construction, the scaffolding using iron pipes as the basic components is generally welded with several iron pipes in the factory to form a frame-type integrated component. The problem of its own large specific gravity makes the scaffolding parts using this kind of integrated components labor-intensive and difficult to construct in the process of handling and assembling, and it cannot be folded and piled up in storage, which takes up a lot of space and increases storage costs. And when this single tower, twin towers or scaffolding are to be disassembled and transported after use, due to the characteristics of welding that cannot be disassembled arbitrarily, the scaffolding of this structure can only be used as non-reusable or fixedly connected. Parts or time-consuming and labor-intensive dismantling methods at the expense of damaging parts and increasing handling difficulties

Moreover, the support frame made of iron pipe is easy to rust and stick to cement and other sundries, which not only affects the appearance of the support frame body, but also reduces the service life of the support frame body.
