CCTV’s SUPPORTS

Metal support of sheet of polygonal or troncoconical section.

In one or several sections, depending on the height.
When they go in several sections they are superimposed with overlapping by mechanical tracter. 

Heights: 

           Troncoconical up to 12 meters. 

           Poligonal up to 20 meters. It´s possible it is possible to concrete from 12 meters to minimize the oscillations of the support.

In its upper end it has a support plate prepared for fixing a CCTV camera, previous design. And a window for output of internal cables and connection to camera.

At its lower end the support is prepared with an anchor plate reinforced with brackets for fixing to the foundation block by means of anchor bolts.

The placement of the control boxes frame support is done at the desired height.

The support design and calculation is performed in accordance with the harmonized standards EN 40-3-1 and EN 40-3-3. 

The corrosion protection is according UNE ISO 1461 standard which is guaranteed by galvanized immersion in molten zinc.

For the calculation of the foundation, we proceed to the calculation using the method Sulzberger, which is based on a verified experimentally principle that for limited inclinations of the joint support-foundation at an angle “a” relative to the vertical, such that “tg alpha”, the field behaves elastic. 

This calculation method establishes an equilibrium condition that must be met: 

Me/MV= c.s 

Where:

Mv is the overturning moment of the structure. 
Me is moment to balance or stabilizing terrain. 
c.s is the safety factor, which is set to 1.5.
