Method for manufacturing brakeless lightweight concrete poles

Abstract

A method of manufacturing concrete lightweight pole 5 and 3 respectively related to electric concrete pole to carry luminaries (street lights), power lines, communication cables and traffic signal lights. This new manufacturing method is using any size steel bars reinforcements 6 in the longitudinal direction of the pole with the horizontal stirrups 8 to adjust strength. This metallic structure secured with wire size 1/16″ diameter is combined with a lightweight high performance fiber cellular concrete mixture 4 , to form after 16 to 24 hours period curing process time, a lightweight unbreakable concrete pole with maximum bending movement.

1 - A method of manufacturing a lightweight concrete pole, unbreakable, solid, strong and easy to handle, particularly an electric pole that can carry luminaries (streets lights), power lines communication cables and traffic signal lights. These poles can be used anywhere, therefore safe and not being an hazard to traffic compared to others. The materials that go into the manufacturing of these poles are: 
 Lightweight fiber cellular concrete mixture  4  (FRCC) weighting 73 lbs/ft3 with adjustable density up to 7000 PSI    Any size diameter ordinary steel bars  6  and  8  combination are used as structural metallic reinforcement. Said, ordinary ½″ and ⅝″ or ¾″ diameter steel bars are used to form a metallic longitudinal structure  6  and ¼″ ordinary diameter steel bars are used to form square or circular stirrups  8  are horizontal reinforcements. This metallic structure is tied and secured with wire size 1/16″ diameter.    
   
   
       2 - A lightweight concrete pole according to  claim 1  made of fiber reinforced cellular concrete  4  contains the following raw materials: thermoflex additive, Portland cement, lightweight aggregate, synthetic fiber (such as polypropylene fiber), fine sand and water.  
   
   
       3 - A lightweight concrete pole according to  claim 1  that have the ability to adjust its vertical and horizontal strength and improve its elasticity by: 
 a) Adjusting stirrups  8  gaps in vital section h 2  of the pole.    b) Placing large diameter steel bars ( 6 , 8 ) longitudinally or vertically.
