[0002] Indoor decorative ceilings occupy a large proportion in today's increasingly rich architectural effects. The ceiling structure is a structural system that transfers the load to the floor of the building structure through ceiling decoration materials such as primary and secondary keels, hangers, and fixed points. There are two commonly used connection methods between the ceiling and the structure: one is to pre-embed anchor bars on the floor, weld one end of the hanger to the pre-embedded anchor bars, and the other end of the hanger is connected to the ceiling; the other is to fix the angle code to the floor by installing mechanical bolts, so that one end of the hanger is fixedly connected to the angle code and the other end is connected to the ceiling. Most of the existing public technologies are the above two connection methods, but these two connection methods are suitable for floors with reinforced concrete on the upper part. According to the specifications, it is not advisable to drill holes on the floor during the construction of steel structure floors to avoid affecting the structural stress. Therefore, the above two conventional connection methods are not suitable for steel structure floors. For this, it is necessary to develop a connection method for the ceiling and structure suitable for steel structure floors to solve the problem that holes cannot be drilled in steel structure floors and the ceiling structure lacks anchor points.

Figure 1-3 , the preferred embodiments of the utility model are further described in detail:

[0025] like Figure 1-3 As shown, a preferred steel structure floor decoration hanging connection assembly of the utility model includes a C-shaped hanger 2, a conversion beam 3 and a hanger 4, wherein the C-shaped hanger 2 is hung on the lower flange of the H-shaped steel beam 1, the lower end of the C-shaped hanger 2 is connected to the conversion beam 3, and the lower end of the conversion beam 3 is connected to the hanger 4.

[0026] The C-type hangers 2 are arranged in pairs, and the upper hanging arms of the two C-type hangers 2 arranged in pairs are symmetrically hung on the lower flange of the H-shaped steel beam 1. The C-type hangers 2 are made of 5# galvanized channel steel, the length of the hanging arms is not less than 50mm, and the surface treatment is hot-dip galvanizing. The thickness of the galvanized layer is 80μm. The upper hanging arm and the lower hanging arm of the C-type hanger 2 each have a bolt hole. The bolt hole of the upper hanging arm has an aperture size of 6mm. The bolt hole is used as a connecting hole to insert a non-slip bolt 5 that matches its thread. The bolt hole of the lower hanging arm has an aperture size of 10mm and is connected to a connecting bolt 6 as a fixing hole. An elastic gasket 7 is installed between the H-shaped steel beam 1 and the C-type hanger 2. The elastic gasket 7 is made of rubber and has a specification of 50mm×50 mm×5mm, a bolt hole is opened in the middle of the elastic gasket 7 for inserting the anti-slip bolt 5, and the bolt hole on the elastic gasket 7 can effectively prevent the C-type hanger 2 from slight slipping, and the anti-slip bolt 5 adopts an M6 bolt, and the anti-slip bolt 5 is provided with an anti-loosening spring 9, and the top end of the anti-loosening spring 9 is against the screw head at the top of the anti-slip bolt 5, and the bottom end of the anti-loosening spring 9 is against the top surface of the hanging arm on the C-type hanger 2. After the suspension rod 4 is subjected to force, the C-type hanger 2 and the elastic gasket 7 are connected and fixed to the H-shaped steel beam 1 with the anti-slip bolt 5 with the anti-loosening spring 9 through the reserved bolt hole, and the anti-loosening spring 9 applies its own elastic force to the anti-slip bolt 5 and the elastic gasket 7, so as to prevent the C-type hanger 2 from slipping through the elastic force.

[0027] The conversion beam 3 is made of 8# galvanized channel steel, with a length of 300mm, and is surface treated with hot-dip galvanizing. The thickness of the galvanized layer is 80μm. A plurality of connection holes are opened on the upper part of the conversion beam 3. The plurality of connection holes are opened at intervals and arranged in a row along the axial direction of the conversion beam 3. The distance between the centers of two adjacent connection holes is 30mm, and the aperture size of the connection hole is 10mm. The fixing hole of the lower hanging arm of the C-shaped pendant 2 is vertically aligned with the connection hole on the upper part of the conversion beam 3. The aligned fixing hole and the connection hole are fixedly connected by connecting bolts 6. The connecting bolts 6 are M8 bolts. A matching nut is fixed to the upper surface of the hanging arm and the lower surface of the upper part of the conversion beam 3, respectively, and gaskets are arranged between the C-shaped hanger 2 and the matching nut and between the conversion beam 3 and the matching nut, respectively. The arrangement of the gasket can make the fixing effect of the connecting bolt 6 better; a hanger rod hole is opened in the middle position of the lower part of the conversion beam 3, and a hanger rod 4 with a thread passes through the hanger rod hole, and the hanger rod 4 is fixed with fixing nuts 8 on the upper and lower sides of the hanger rod hole. This double-nut fixing method can not only make the hanger rod 4 more firmly fixed on the conversion beam 3, but also can change the hanging length of the hanger rod 4 by adjusting the fixing nut.

[0028] Both the C-shaped hanger 2 and the conversion beam 3 are made of channel steel. The channel steel has great rigidity and better bearing effect. At the same time, the upper and lower hanging arms of the channel steel have a certain distance and are grooved, which is convenient for the installation of the connecting bolts 6 and the fixing nuts 8. The channel steel is galvanized to achieve a good anti-corrosion effect and increase the service life.
