The construction fastener belongs to the field of construction machinery parts

   Construction fasteners can be steel, wood, bamboo materials, each piece should not be greater than 30kg. Stamping steel footboard material should be the symbol of the current national standard "carbon structural steel" (GB / T700) in the Q235-A grade steel requirements, construction fasteners must have sufficient strength, durability, and a certain flexibility, and effective Keep a reliable connection between the rail and the sleeper. In addition, also requires less fast parts of the system, the device is simple, easy assembly. Bowl buckle connection is simple, commonly used in domestic construction fastener cast iron production. Which can be adapted to a variety of flat, facade of the buildings and structures with scaffolding. Comparison of economy. Simple processing.

   The form bracket of the construction fastener type steel pipe stent must be provided with a horizontal and vertical sweeping pole. Longitudinal sweeping pole should be fixed at right angles to the base of the epithelium is not greater than 200mm on the pole, the horizontal sweep pole should also be used at right angle fasteners fixed in the vertical sweeping pole below the pole.

   The second is in the smelting → tapping → casting process in the implementation of multiple deoxidation, the third in the ladle with the casting, depending on the deoxidation situation, the use of cast steel, With the addition of aluminum deoxidation; sand casting, heat treatment after cooling with the furnace. This method is reasonable, the process parameters are appropriate, the efficiency is high and the cost is low, the fastener strength is high, the toughness is good, it is the ideal product of high-rise and super high-rise building construction.

   The construction fastener belongs to the field of construction machinery parts, which consists of two sub-fasteners. The lower part of each sub-fastener is connected with the live bolt, and the big end is connected with the upper fastener with the opening and the thrust surface , Between the two sub-threaded riveting joints, and at any angle rotation. The construction fastener ensures that the steel pipe and the fastener are in contact with the state, the area is large, to overcome the cast iron fastener and steel pipe was point or line fit shortcomings, eliminating the risk of steel pipe slippage, Thus ensuring the safety of the construction fastener and repeat the effective use of the whole parts of the construction by the passivation and galvanized double anti-corrosion treatment, long life, far more than the life of cast iron fasteners; construction fasteners using new connections, The new nut ensures that in the case of deformation of the steel pipe, fasteners can always be fixed firmly fixed, eliminating the possibility of steel slippage. machinery parts
