Compared with concrete structures, prefabricated steel structures are lighter in self-weight and lower in foundation cost; they are more convenient to assemble.

[0003] As is well known, in most public places, the columns are usually cylindrical in shape and are made by means of concrete pouring. In order to meet the different needs of people, sometimes it is necessary to transform the cylindrical column into a square column to meet the requirements of decoration and practical applications. With the rise of prefabricated steel structures, the prefabricated column-wrapping structure is a column structure used in prefabricated buildings, which mainly plays a decorative role and does not need to play a supporting role, and it is also more and more widely used in the construction field.

At present, most traditional column-wrapping structures are traditional decoration processes, using reinforced concrete columns, making a light steel keel, and outsourcing aluminum plastic panels, etc. However, there are very few conversion processes for prefabricated steel structures, and there are also few suitable conversion components for reference. Installation accuracy cannot be guaranteed only relying on the technical experience of construction workers. Therefore, this application aims to provide a prefabricated steel structure construction structure and scheme that can be adopted when a cylindrical column needs to be wrapped into a square column during the decoration process, and it conforms to the characteristics of fast installation and quick disassembly of prefabricated steel structures.

Fireproof paint is sprayed on the outer side of the round steel column 1, and the material of the pre-welded hoop member 2 is stainless steel.

[0038] The pre-welded hoop member 2 of the present invention is the main conversion component for changing a cylindrical column into a square column. The pre-welded hoop member 2 includes a right-angle angle code 21, a three-fold bending member 22, and a flat joint member 23 that are cooperatively connected. The right-angle angle code 21 is welded and fixed on the round steel column 1, the three-fold bending member 22 is fixed on the right-angle angle code 21, one end of the flat joint member 23 is fixed on the three-fold bending member 22, and the other end is fixed on the three-fold bending member 22 of the adjacent pre-welded hoop member 2. The present invention adopts a combined technical solution of pre-welding and hooping, making use of the advantages and compensating for the disadvantages, and the overall structure is more stable;

[0039] Among them, the right-angle angle code 21 includes a first side plate 211 and a second side plate 212 that are vertically arranged, and vertical waist-shaped holes 4 are provided on both the first side plate 211 and the second side plate 212; the three-fold bending member 22 is a three-bending structure, including a first folding plate 221, a second folding plate 222, a third folding plate 223, a fourth folding plate 224, a fifth folding plate 225, and a sixth folding plate 226 that are sequentially vertically arranged.
