The difference between octagon bar and other multilateral rod

Octagon bar and other polygon pole when zoned bisectrix? Must be careful crossing scale accurate? Uniform line number whether right? Not much? Cannot little. When the steel plate bending careful point of view? To lap seam is flat and level. Welding inspection of joint machine each

 octagon bar' Anise rod, mainly used for the installation of cameras and fixed lights, traffic signs is widely used as the main purposes. 】 And other polygon pole when zoned bisectrix? Must be careful crossing scale accurate? Uniform line number whether right? Not much? Cannot little. When the steel plate bending careful point of view? To lap seam is flat and level. When welding inspection of the joint machine parts can be normal? Especially the pressure bands and pulleys. If found the problem? Need immediate repair? Can't repair? A change in a timely manner. Check whether there is any problem on flux. Such as solder wetting required drying? Such as the flux by oil pollution and presents the oxidation slag? The contaminated local can't use. At the end of the rod joint? According to the drawings can count number is correct? When the pile pole? Should prevent the rod presents the impact? Will never allow bands appear rugged phenomenon as a result of strokes. 1, control rod is used for outdoor surveillance cameras distance monitoring equipment of columnar stent generally use cross arm 6 meters 1 meter to stop manufacturing. No special circumstances all monitoring poling 【 Monitoring poling also called monitoring pole, divided into anise monitoring pole, circular tube monitoring, monitoring such as diameter rod, variable diameter monitoring pole, conical monitoring pole, highly general for 3 - 6 meters, mainly for road transportation, intersection, schools, government, community, factories, frontier defense, airports where the surveillance camera. 】 Embedded parts for C25 concrete, concrete reinforced by agree with national standard and the wind begged. In the cement for ordinary Portland cement, 425 【 Ordinary Portland cement, the silicate cement clinker, 5% 20% of the hybrid materials and a moderate amount of gypsum made of mill hydraulic cementing materials. 】 。 The ratio of concrete and minimum cement dosage should be agree with GBJ204 - The rules of the 83; 2, must have outstanding grounding best plus import lead exposed ( Don't go advocated conducting rod body) , the grounding resistance less than 4 o 3, embedded anchor bolt 【 Mechanical components are installed on the concrete foundation, the bolt of the J shape, one end of the l-shaped embedded in concrete are used. 】 Above the flange thread bandaging outstanding for damage. Figure positioned properly monitor based on embedded parts equipment embedded parts, ensure the arm stretched out straight direction and driveway ( Or by the engineer begged) Anchor bolt as the main reinforcement; 4, control rod foundation concrete surface roughness is less than 5 mm/m try to stick to stud embedded parts. Embedded parts flange low out of the air around 20 ~ 30 mm, reoccupy C25 fine stone concrete cover the reinforced rib, in order to prevent the water; 5, beside the lever and control box, 【 The control box is used widely. 】 Beside, cable bend, cable pipe' Cement cable pipe also known as power line cable, power cable pipe, cement pipe, cement cable, power cable pipe cement, etc. 】 Straight line length beyond 50 meters or two cable tube is not in the same plane are more than 100 mm apart, must set hand hole Wells [ Hand hole Wells is refers to the buildings or for the convenience of laying cable in municipal engineering, build the can't go to people, can only be reached in the well and convenient threading, general is given priority to with cement block structure. 】
