In daily life, zippers are often used to connect two different components such as hooks and hooks, but in the field of construction engineering, fasteners are also very important construction auxiliary tools, mainly new fasteners, steel pipe scaffolding Fasteners, cast steel fasteners, concrete, steel pipe scaffolding as a common construction component, the main function is to fix steel pipe fasteners scaffolding, then, let's understand the basic knowledge and precautions of steel pipe fastener scaffolding together!

Definition and classification of 1. steel pipe fastener scaffold

The steel pipe fastener scaffold is a connector connecting the rail and the sleeper. Its function is to fix the rail on the sleeper, fix the gauge, prevent the vertical and horizontal movement of the rail relative to the sleeper, and is mostly used to fix the steel pipe scaffold with an outer diameter of 48mm in construction projects. The main fasteners commonly used in scaffolding in domestic construction projects are right-angle fasteners (cross fasteners and directional fasteners, rotating fasteners, movable fasteners and universal fasteners, straight fasteners and direct fasteners 3 kinds.

1. The right-angle fastener is connected to two fasteners forming a vertical cross steel pipe.

2. Rotate the fastener to connect two steel pipes crossing at any angle.

3. The butt fastener connects 2 butt steel pipe fasteners.

Quality standard for 2. steel pipe fastener scaffold

Steel pipe fasteners and scaffolding connectors are mostly used in construction, electric power, municipal administration, water conservancy, chemical industry, metallurgy, coal and ship projects involving peripheral protection structures, construction platforms, safety barriers, formwork supports, foundation pit support and other safety protection parts. Therefore, it plays an important role in various safety construction and protection work. Steel pipe scaffolding

3. steel pipe fastener scaffold use matters needing attention

To improve the product quality of fasteners and the safety in use, it is necessary to strictly control not only the quality of fastener products, but also the use of fasteners. The correct use method not only ensures the safety of construction, but also helps to extend the life of fasteners. The following five-point steel pipe scaffold fastener use matters needing attention is worth the construction unit strictly abide by and master.

1. Before the construction of steel pipe fastener scaffold, the construction plan shall be formulated, and a more strict and thorough construction plan shall be formulated. If the scheme is not well formulated, unexpected safety incidents may occur during construction.

2. Install steel pipes and fasteners used for fastener-type formwork, and conduct sampling inspection before use. Check whether the quality and appearance of steel pipes and fasteners meet the standards by sampling. The quantity of sampling inspection shall be carried out in accordance with the relevant provisions, and the sampling inspection shall be carried out according to a certain proportion, and those that have not been inspected or failed in the inspection shall not be used.

3, often check the appearance quality of fasteners. The surface of the fastener shall be subject to anti-rust treatment (asphalt coating is not allowed). The paint shall be uniform and beautiful, and there shall be no paint pile and iron exposure. The contact part between the fastener and the steel pipe shall not have oxide scale, and the accumulated oxidation area of other parts shall not exceed 150 mm2; Do not use fasteners with cracks, deformation and bolt slippage to avoid construction failures and accidents caused by using these unqualified fasteners. 4. The adhesive surface of the fastener and the steel pipe shall be strictly reshaped to ensure the sliding and tensile performance requirements of the fastener. The movable part can be flexibly rotated. The gap between the two rotating surfaces of the rotating fastener shall be less than 1mm.

5. Regarding the loading capacity of fasteners, the construction load of the working layer shall meet the design requirements and shall not be overloaded. A certain weight cannot be loaded. Scaffolding shall not be attached to formwork supports. During the connection, certain treatment is carried out to ensure the reasonable bearing weight of the fastener.

Manufacturers of construction fasteners call for strict quality control in the production process to ensure that all fasteners meet national quality standards. At the same time, it is recommended that construction personnel purchase regular qualified products, operate in strict accordance with construction requirements, minimize the number of fastener recycling, avoid excessive use of fasteners leading to fatigue damage, safe production, and prevent accidents.

The above introduction is the basic knowledge and precautions of steel pipe fastener scaffolding. If you need to know more, please feel free to contact us!
