What are the main construction and installation steps of video surveillance pole

The main construction and installation steps of the video surveillance pole are as follows: first dig a foundation pit, then embed the floor cage, then pour concrete, and finally fix the pole on the installation surface of the floor cage.

The reinforcement cage of the foundation should be taken fixed measures before pouring concrete, and at the same time to ensure that the reinforcement pet foundation roof plane level, that is, the level in the foundation roof vertical two direction measurement, observe the bubble must be centered; Monitoring pole embedded parts of the foundation concrete pouring must be dense, concrete empty drum is prohibited.

The bolts that fix the pole on the floor cage should not be smaller than M20, and the height of the threaded part extending out of the floor cage foundation is greater than 70mm. The strength grade of all the nuts, gaskets and other structural parts used should not be lower than 8.8 and have the ability of anti-corrosion for more than five years.

Since the height of the video surveillance pole is roughly between 4 and 6 meters, the overall verticality requirement is not too high, so as not to affect the use and beauty of the appropriate, when formulating the standard of verticality deviation may consider more aesthetic factors.

When the vertical deviation of the pole is about 1%, it is almost undetectable visually, while when the deviation reaches 2%, the human eye can easily detect the tilt of the pole. Therefore, it is appropriate to set the standard of verticality deviation as 1%, which will greatly improve the construction requirements and thus affect the progress of the project.

The perpendicularity control method of flange and rod body in the production and processing of conical pipe pole

To ensure that the vertical rod is vertical to the horizontal plane, the most important point is to ensure that the vertical rod mounting flange is vertical to the main shaft before leaving the factory. If this verticality is not effectively guaranteed, then the vertical of the rod after installation will appear completely out of control. The perpendicularity of the rod mounting flange and the rod body depends largely on the welding process between them.

At present, most separate rod manufacturers do not pay enough attention to the welding of flange and rod body, which is embodied in the lack of test tooling and method standards. This method describes the specific operation procedures for confirming the verticality between flange and pole body before welding, and the method is simple and easy to implement.
