b< c=>Shelf pipe
b< c=> is a kind of construction pipe covering the building pipe. It is mainly used to make construction site supports. It is made of hot-rolled strip steel after processing. finished product. Usually one bundle is the root. The length of each pipe is meters and it is a type of welded pipe. The material is B frame tube. The implementation standard is B/straight seam electric welded steel pipe. Sales are often priced based on theoretical weight. The outer diameter size is. The main production bases are in Tangshan and Tianjin. Also called scaffolding tube, scaffolding steel pipe. At present, the weight of the national standard scaffolding pipe per meter is..., and the thickness is... Use together with fasteners.

b Shelf pipes refer to various supports erected at the construction site for workers to operate and solve vertical and horizontal transportation . A general term in the construction industry refers to a construction site used on exterior walls, interior decoration, or places where direct construction is impossible due to high floor heights. It is mainly used for construction workers to work up and down or to maintain peripheral safety nets and install components at high altitudes. To put it bluntly, it is to build scaffolding. Scaffolding materials usually include: bamboo, wood, steel pipes or synthetic materials, etc. Scaffolding is also used as a template in some projects. In addition, it is also widely used in the advertising industry, municipal administration, traffic roads and bridges, mining and other departments.

b Fastener type steel pipe scaffolding) is easy to assemble and disassemble, and is flexible to erect. Because the length of the steel pipe is easy to adjust and the fasteners are simple to connect, it can be adapted to scaffolding for buildings and structures of various planes and elevations. ) is relatively economical. The processing is simple and the one-time investment cost is low. If the geometric dimensions of the scaffolding are carefully designed and attention is paid to improving the turnover rate of steel pipes, the amount of material used can also achieve better economic results. The fastener steel pipe frame is equivalent to approximately kilograms of construction steel per square meter.

b) You should have a clear understanding of heavy-duty scaffolding. Generally, if the thickness of the floor exceeds Consider designing according to heavy-duty scaffolding. If the scaffolding load exceeds /, the design plan should be organized for expert demonstration. It is necessary to distinguish which parts of the steel pipe length change have a greater impact on the load-bearing. For the formwork support, it should be considered: the distance between the center line of the top horizontal rod and the formwork support point should not be too long, generally less than 100% (it may be required in the new specification) (revised), when calculating vertical poles, the top step and the bottom step generally bear the greatest force and should be used as the main calculation points. When the bearing capacity does not meet the group requirements, vertical poles should be added to reduce the vertical and horizontal spacing, or horizontal poles should be added to reduce the step distance. . Theoretical calculations during construction do not take these into account, so it is best to adopt a certain safety factor during the design calculation process.
