Description

Technical Field

[0001] The invention belongs to the field of construction devices, and in particular relates to an adjustable purlin support and a construction method thereof. Background Art

[0002] With the continuous development of production and the improvement of people's social activities, it is necessary to build large-span industrial plants, exhibition halls, stadiums, raw material storage yards and greenhouses and other buildings and structures to meet the growing needs of production and people's lives. The grid structure is the best choice for large-span open-air storage yards and greenhouses because of its unique advantages such as light weight, short construction period, low cost, good seismic performance and high rigidity. Therefore, large-span grid installation technology has become a current development trend. The most common one is the bolt ball grid. Because the size of the sphere of the bolt ball grid is different, in order to ensure the smooth installation surface of the external color steel plate, a grid project purlin is usually designed with hundreds of specifications. The height difference of the bolt ball plane is compensated by the height difference of the purlin. There are tens of thousands of them installed on site, which is a relatively complicated task and requires a lot of manpower time for processing and assembly. Most of the existing purlins are prefabricated in factories. First, there is a certain error in the height of the purlin, which will cause the height of the grid after installation to be uneven and require manual cutting. Second, grids of different sizes require purlins of different sizes. Such production cannot be standardized and the production is relatively complicated. Therefore, it is necessary to explore and design a height-adjustable purlin for factory processing to reduce the workload of processing and classification. Summary of the invention
