: Purpose of shelf tubes: Shelf tubes 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. &<: Characteristics of scaffolding tubes: Different types of engineering construction use scaffolding and formwork supports for different purposes. At present, most bridge supports use bowl-buckle scaffolding, and some also use portal scaffolding. Most of the floor-standing scaffolding used in the construction of the main structure uses fastener scaffolding. The longitudinal distance of the scaffolding poles is generally .~. The horizontal distance is generally .~. &<: Advantages of shelf tubes: Fastener-type steel tube 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. &<: Design of shelf tubes:) You should have a clear understanding of heavy-duty scaffolding. Generally, if the thickness of the floor exceeds, you should 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 length from the center line of the top horizontal bar to 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. <: At present, it is common for domestic scaffolding to have substandard materials such as steel pipes, fasteners, jacks and bottom brackets. These are not taken into account in theoretical calculations during actual construction. It is best to adopt a certain safety factor in the design calculation process.
