The optimal price, the most complete protection, Address: Changsha steel market Yili Logistics Park, Mr. Chen: 15111375176,13973198271 QQ: 173469790 www.hnssdgroup.com tube rack, is a building pipe rack pipe levy, mainly used to produce building site support, is a hot strip after Process rolled products. Generally bundle for 91. Each length of 6 m, is a pipe. Q235B material for pipe rack. Implementation of the standards is GB / T13793-2008 straight seam welded steel pipe. When selling mostly denominated in theoretical weight. The outside diameter of 48MM. The main production base in Tianjin, Tangshan and pipe rack. Also known as the scaffold tube, steel pipe scaffold. Currently national standards scaffold tube weight per meter for 3.84kg, a thickness of 3.5mm. Together with supporting the use of fasteners. Rack uses: rack tube means for workers to operate the construction site and resolve the vertical and horizontal transport and erection of various bracket. Generic term construction industry, refers to the construction site for use in exterior walls, interior or story high places can not direct the construction. Mainly for construction workers to work up and down or perimeter security net maintenance and installation of components such as high altitude, that white is put on airs, scaffold production of materials usually have: bamboo, wood, steel or synthetic materials. Some projects also used as a template to use scaffolding, in addition to the advertising industry, municipal, transportation roads and bridges, mining and other sectors are also widely used. Tube rack features: choose different types of construction scaffolding and templates for different purposes bracket. Currently, the use of a bridge support bracket scaffold Bowl majority, but also the use of scaffolding gantry. Main floor scaffolding structure construction scaffolding fastener mostly scaffolding pole vertical distance is generally 1.2 ~ 1.8m; horizontal distance is generally 0.9 ~ 1.5m. Advantages shelf pipe: steel tubular scaffolding 2) easy assembly and disassembly, erection and flexible. Due to the length of pipe is easy to adjust, easy to connect fasteners, which can be adapted to a variety of flat facades of buildings and structures with scaffolding. 3) Comparison of the economy. Processing is simple, a lower investment cost; if well-designed scaffold geometry, focus on improving the utilization of steel turnover, the amount of material can also achieve better economic results. Fastener steel frame construction steel equivalent per square meter is about 15 kg. Pipe rack design: 1) for heavy scaffolding should have a clear understanding, if the slab thickness generally exceeds 300mm, it should be considered in accordance with the heavy scaffolding design change, scaffolding load over 15KN / mm2, the design should organize experts. To make it clear to those parts of the pipe carrying a greater impact on the change in length, should be considered for the template bracket: a horizontal bar top centerline length of the anchor from a template should not be too long, generally less than 400mm is appropriate (in the new specification may have to be revised), generally the top and bottom step by step maximum force, should be the main computing point pole calculations. When dissatisfied group carrying capacity requirements should reduce vertical and horizontal spacing to increase the pole, reduce or increase the horizontal bar pitches. At present, the prevalence of substandard steel scaffolding, fasteners, backwater and the end of care, such as the quality of materials, the actual construction of the theoretical calculation does not take into account these, it is best to take certain safety factor in the design calculations. ● ensure cash supply, resource channels open ● Special specifications can be ordered ● User agreement requires new indoor storage, the introduction of advanced handling equipment ● owned four trucks, * transportation, delivery ● holidays as usual delivery
