Shelf pipe Shelf pipe is a kind of building pipe and floor shelf pipe. It is mainly used to make construction site supports. It is a product rolled from hot-rolled strip steel after processing. Usually one bundle is the root. The length of each pipe is meters and it is a type of welded pipe. The material is shelf tube. The implementation standard is /straight seam electric welded steel pipe. Sales are often priced based on theoretical weight. The outer diameter size is. The production base is located in the Shengshida factory building of Hunan Steel Market. Shelf pipes are also called scaffolding pipes and scaffolding steel pipes. At present, the national standard scaffolding pipe has a weight per meter and a thickness of . Used together with fasteners, the fasteners operated by our company mainly include cross buckles, direct buckles, and universal buckles. When selling rack tubes, they can also be sold with fasteners.
Purpose of rack pipes
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. 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 Pipes
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
The fastener-type steel tube scaffolding is easy to assemble and disassemble, and is flexible in erection. 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 those parts where the change in the length of the steel pipe has a greater impact on the load-bearing. For the formwork support, it should be considered that 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%. (This 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 requirements of the group, 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 unqualified materials such as steel pipes, fasteners, jacks and bottom brackets. The current actual construction The theoretical calculation does not take these into account, so it is best to take a certain safety factor in the design calculation process.

Fastener-type steel pipe scaffolding
Scaffolding and support frames composed of fasteners and steel pipes that are erected for construction and bear loads are collectively referred to as scaffolding. Fasteners are fasteners that are fastened with bolts.
Introduction The commonly used fastener-type steel pipe scaffolding in China is made of cast iron, and its mechanical properties should comply with the "Steel Pipe Scaffolding Fastener-type Steel Pipe Scaffolding" () material no less than. It is also required that the fastener-type steel pipe scaffolding system has fewer parts, is simple to install, and is easy to disassemble. In addition to cast iron fastener-type steel pipe scaffolding, there are also steel fastener-type steel pipe scaffolding. Steel fastener-type steel pipe scaffolding is generally divided into cast steel fastener-type steel pipe scaffolding and steel plate stamping and hydraulic fastener-type steel pipe scaffolding. The production process of cast steel fastener-type steel pipe scaffolding is roughly the same as that of cast iron, while steel plate stamping and hydraulic fasteners Type steel tube scaffolding is made of steel plates pressed through stamping and hydraulic technology. Steel fastener type steel pipe scaffolding has superior properties, such as break resistance, slip resistance, deformation resistance, detachment resistance, rust resistance, etc.
Fasteners are connections between steel pipes. There are three types of fasteners, namely right-angle fasteners, rotating fasteners, and butt fasteners
Right-angle fasteners are used to connect two vertically intersecting steel pipes. It relies on the friction between the fastener and the steel pipe to transmit the load.
Rotating fasteners are used to connect two steel pipes that intersect at any angle
Butt fasteners are used to connect two long steel pipes butt joints.
