Description

Steel structure roof double C-shaped purlin hanging pipe installation support and hanger device

technical field

The utility model belongs to the technical field of installation and construction of suspended pipe support and hangers, in particular to a support and hanger device for installing double C-shaped steel hanging pipes on steel structure roofs.

Background technique

During the construction process of the erection support and hanger system of the suspended pipeline line inside the traditional steel structure building, it is basically necessary to add a corresponding number of structural secondary beams on the steel structure column and main beam, so as to provide stress nodes for the later installation of the top pipeline line; In this way, the load of the suspended pipeline inside the building can be indirectly transmitted to the main stress-bearing structure of the building through the support and hanger system connecting the primary and secondary beams, and most of the connection nodes in the above-mentioned processes are welded connections. This method makes the suspended pipe completely separate from the roof structure during the overall erection process, so the construction according to the above method will not affect the quality of the final product of the roof structure.

However, the above method has obvious disadvantages, such as: increasing the difficulty of the overall design; adding a certain amount of secondary beams only to install the pipeline, which not only increases the construction cost, but also increases the load of the overall building; and correspondingly increases the construction cost. The labor cost and later maintenance cost of the enterprise; it is not conducive to the promotion of green buildings and carbon comprehensive energy-saving and environmental protection development in the construction industry, so the traditional installation method of pipe supports and hangers is no longer suitable for today's light steel roof buildings such as factories and exhibition halls construction of things.

Relying on a research and development base project, the research on the pipe support and hanger system under the steel structure roof was carried out. The factory building project is a metal roof, and the outer eaves and curtain walls are also made of metal. The overall building is a cuboid building. The bearing structural beams of the partial roof are flat C-shaped steel purlins, and the building height is between 14.5m and 21.7m. The height of the flat C-shaped thin steel purlin metal structure roof is 14.5m, and there are many types of equipment in the factory building. Therefore, cable pipelines, ventilation pipelines, water supply and drainage pipelines and other pipelines are laid very densely. Directly hang and lay along the C-shaped thin steel purlins on the roof. Moreover, the roof purlin is a single C-shaped thin steel building material component. After calculation, the load borne by the C-shaped thin steel purlin is relatively low, and a single C-shaped thin steel purlin cannot bear the total load brought by the pipeline in the overlapping parts of the pipeline. , and because the C-shaped thin steel purlins are mostly placed sideways with openings during the construction process, the left and right sides of the C-shaped thin steel purlins are asymmetrical. If the purlin rolls over and loses stability, it will cause serious damage to the overall quality of the roof, affect the comprehensive use function in the later stage, and pose serious safety hazards. Therefore, the conventional support and hanger pipeline installation construction technology cannot solve the problems encountered in current construction projects.
