Multi-layer large-span assembly building structure

Abstract

The invention discloses a multi-layer large-span assembly building structure which comprises a box body and a paint spraying nozzle. The multi-layer large-span assembly building structure further comprises a storage box, a vertical rack, a first gear, a first belt pulley, a second belt pulley, a second gear, a third gear, a first half-tooth gear, a second half-tooth gear, a transverse rack, a paint box and an oil cylinder. A to-be-painted part is taken out from the storage box, the storage box moves upwards, the vertical rack moves upwards, the first gear rotates, the first belt pulley rotates, the second belt wheel rotates, the second gear rotates, and the first half-tooth gear rotates; and the third-gear rotates, the second half-tooth gear rotates, when the first half-tooth gear is engaged with the transverse rack, the transverse rack moves leftwards, paint flows into the paint spraying nozzle, the paint spraying nozzle sprays paint to the part, rotation of the second gear enables the third gear to rotate and the second half-tooth gear to rotate, and when the second gear is engaged with the transverse rack, the transverse rack moves rightwards, and the paint flows into the oil cylinder from the paint box. According to the scheme, the structure is simple, and power resources are saved.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a multi-layer and large-span assembled building structure. Background technique [0002] With the continuous development of society and the vigorous development of the construction industry, people pay more and more attention to architectural aesthetics, and multi-layer and large-span assembly building structures have gradually become the mainstream of architecture. Multi-storey and long-span assembly building structures are mostly used in large-span workshops, aircraft assembly workshops and large warehouses in industrial buildings. Nowadays, multi-layer and long-span assembly building structures are one of the important symbols of a country's architectural technology level. [0003] The existing multi-storey and long-span assembly building structure includes: multi-layer long-span concrete honeycomb hollow sandwich floor and grid frame, each long-span concrete honeycomb hollo...

Problems solved by technology

However, for some metal parts, the metal parts are easy to get rusty. In the prior art, the surface of the metal parts is usually painted in the factory, and then transported to the construction site. The paint on the metal surface is easily damaged and unsightly during transportation.
