Masteel fasteners are a kind of fittings used with rack pipes. Masteel fasteners produced by Yanxin Senyu are relatively rigid. After two corrections, the central axis is thickened and the hoop is thickened. In addition, the screws and nut washers used by the Masteel fasteners are all standard parts. There is no need to find the weight of the accessories. We all know that the correct use of Martensitic fasteners is conducive to prolonging life, so how should it be used?
1. Maanshan Iron and Steel Fasteners, that is, fastener-type steel pipe template brackets, must have a construction plan prepared before construction, and formulate a relatively strict and thorough construction plan. If the plan is not formulated well, some unexpected events may occur during construction.
2. Appearance quality requirements of Maanshan Iron and Steel Fasteners: The appearance quality of fasteners is often tested. If there are cracks, deformations or bolts with sliding threads, it is strictly prohibited to use them; in order to prevent construction failures and accidents when using these unqualified fasteners.
3. Assembling of Maanshan Iron and Steel Fasteners: The steel pipes and fasteners used in the fastener-type template bracket must be sampled before use to check whether the quality and appearance of the steel pipes and fasteners meet the standards. The number of random inspections shall be performed in accordance with relevant regulations. A certain percentage of samples are tested, and they are not allowed to use without testing or failing the test.
4. Regarding the load capacity of the Masteel fasteners, the construction load on the working layer should meet the design requirements and should not be overloaded. It must bear a certain weight. The scaffolding must not be connected to the formwork bracket. When connecting, certain treatment must be performed to ensure the reasonableness of the fasteners. Carrying weight.
The new national standard scaffolding fastener is strictly tested by the National Engineering Supervision and Inspection Center. It has good sliding resistance, drop resistance and deformation resistance. It is suitable for a variety of construction projects and can effectively improve the stability of scaffolding and the safety of construction personnel.
The commonly used domestic Martensite fasteners are made of cast iron, and their mechanical properties should be in accordance with "Steel Pipe Scaffolding Fasteners" (GB15831-2006). The material is not lower than KT330-08. At present, the fastener varieties on the market are mixed, with varying quality. Manufacturers use gray cast iron and ground channel steel to make fasteners, and their mechanical properties are difficult to meet the requirements and are not produced in accordance with national standards.
