Dedules generally refer to the middle connection parts connected to the two components. In the construction engineering, it is mostly used in the fixation of steel pipes with φ48mm φ48mm in the construction project.Dednesses) docking deductions (direct deductions of one word deduction) and scaffolding fasteners.
Scooter deduction weight
According to the national current standard steel pipe deduction, the weight standard is 2.2 pounds of cross deduction and 2.5 catties of docking deductions.Rotate 2.5 catties.Performance name buckle type Performance requirements Requirements to reverse the rigidity of the right -angle torque of 900N · m, when the ⊙≤4 ° C tensile docking P = 4.0kn, △ ≤ 2.0mm pressure -resistant base P = 50.0kn, each part shall not destroy the fastener (Except for the base), it must be tested by the 65N · m torque torque and is not allowed to be damaged.
Types of scaffolding
The commonly used fasteners are cast iron.At present, there are many types of fasteners, mainly new types of fastening, steel pipe scaffolding parts, casting steel buckle, T -type building buckle, concrete pillow buckle, wooden pillow buckle, rail buckle, Fharoto buckle, Mal steel bucklePieces, scaffolding parts, railway buckles, steel plate stamping fasteners, docking fasteners, rotating fasteners, right -angle buckles.
Scaffolding price
1. Chenguang national standard buckle building scaffolding brand: nb model: 48 type: scaffold buckle fastener form: right -angle buckle material: Malga load: 1000 quotation: 3 yuan/piece
Standard of scaffolding
1. The steel pipe scaffolding must be produced in accordance with the patterns approved by the prescribed procedures. The material of the fastening casting should be made of GB9440. The mechanical properties specified by the prescribed forged cast iron or ZG230-450 cast steel in GB11352 should be made.The fitting surface of the buckle and the steel pipe must be strictly shaped, and the requirements of fastening and tensile performance should be ensured.2. The mechanical properties of the buckle and the base should meet the requirements. The deduction (except outside the base) must pass the test pressure test of the 65N · m torque torque. It is not allowed to be damaged.Cracks exist.The open distance between the cover and the seat must not be less than 49mm, the fastening parts are not allowed to have shrinkage in the main parts, the sand eye with a deduction surface is greater than 10mm, and the cumulative area should not be greater than 50m㎡.The area of ??area should not be greater than 150m㎡.
