What is the standard specification of hexagonal mesh machine

Specification of professional skills for preventing highway bridges from being caught. Preventing from being caught is applicable to the overpass bridge with concrete protective fence. The spacing of anti falling net is set at 2m. Pay attention to the proper maintenance of the anchor bolts with expansion screws. The anti catching upright rod and butt plate, the galvanized flat steel of grounding device shall be welded into one, and the butt plate shall be fixed by expansion screws; Except that standard parts and expansion screws are solved by hot galvanizing.
Other prefabricated components of hexagonal mesh machine shall be hot-dip galvanized before plastic plating. The dotted line in the figure is the bend of butt plate. The grounding resistance of the anti falling object net is required to be less than 10. If it fails to meet the requirements, the amount of galvanized angle steel of the grounding body can be increased. The angle steel spacing is 5m, and the galvanized flat steel is used for butt joint. The length of the grounding device at the top of each anti falling object net is just the same as that of the galvanized angle steel. Take the bill of quantities of on-site practical activities as the standard. If you have any questions and interpretation rights, please contact the overall planning staff immediately.
All steel prefabricated members shall be made of A3 steel, and their physical properties shall comply with the provisions of GB / t13793. Before welding, it is required to correct the verticality of each individual member and remove the burrs. The welding position of electric welding is too slippery, and there are no welding defects such as weld beading, desoldering, air outlet hole, etc. the overall correction shall be carried out after the construction and assembly welding. The overall warpage after plastic surgery shall not exceed 7mm. The plastic coating must be symmetrical, soft and bright, without pinhole and fluidity deposition. The thickness of the coating is > 0.25mm, and the color is emerald green. It seems that the regulations refer to GB / t18226 anti corrosion skills for steel components of highway traffic engineering for details.
The hexagonal mesh machine manufacturer solves the problem of hot galvanizing the standard parts to prevent being caught. The amount of galvanizing is 120g / ㎡. A throwing support is set every 60m or turn vertically, and the diagonal support is produced by the manufacturer's supporting facilities. The bottom end of the anti grabbing upright pole is perforated, with a diameter of 11mm. When the engineering construction equipment erect the pole, it passes through 30cm long building reinforcement to improve the reliability of the upright pole.
