Service tower base installation and protective barrier assembly therefor

Abstract

A protective barrier assembly is especially adapted for service tower installations. A pair of pre-cast quasi-U-shaped shells, mate to form a vertically extending enclosure. A pair of caps bridges the shells. A retention rim of the caps extends around the periphery of the enclosure at the upper end. A post for the service tower projects through an opening in the caps. The shells are substantially identical reinforced concrete structures. The caps may also be identical.

1 . A protective barrier assembly comprising:
 a pair of substantially identical pre-cast quasi-U-shaped shells matable in end-to-end relationship to form a vertically extending enclosure with an upper end; and   a pair of caps covering said upper end, each said cap bridging said shells and cooperating to define a central opening and a retention rim extending about the periphery of the enclosure at the upper end of said shells.   
   
   
       2 . The barrier assembly of  claim 1 , wherein said caps are substantially identical. 
   
   
       3 . The barrier assembly of  claim 1 , wherein said caps each have a plate and fasteners extend through the plate for securing together said caps. 
   
   
       4 . The barrier assembly of  claim 1 , wherein the shells have a rectangular opening with a recess, and upon mating said shells form a pair of access openings. 
   
   
       5 . The barrier assembly of  claim 4  further comprising an access cover covering each said access opening and received in a said recess. 
   
   
       6 . The barrier assembly of  claim 1 , wherein the shells are formed from reinforced concrete. 
   
   
       7 . The barrier assembly of  claim 1  wherein each shell is an integral one piece structure comprising an extended wall, a rounded wall and a truncated wall. 
   
   
       8 . The barrier assembly of  claim 7  wherein said rounded wall defines a notch and carrier bar is anchored to said shell and extends across said notch. 
   
   
       9 . The barrier assembly of  claim 7  wherein said extended wall is defined by a rectangular recess. 
   
   
       10 . A service tower base installation comprising:
 a mounting platform;   a tower pole mounted to said platform; and   a protective barrier comprising a pair of substantially identical pre-cast members forming an enclosure surrounding said platform and extending above said platform and having a cover bridging said pre-cast members and defining an opening through which said pole vertically projects.   
   
   
       11 . The base installation of  claim 10  wherein said opening defines a gap surrounding said pole. 
   
   
       12 . The base installation of  claim 10  further comprising a bracket having flanges and a connecting a bottom end of the pole, said flanges receiving fasteners anchored to the mounting platform. 
   
   
       13 . The base installation of  claim 10  wherein the barrier is a modular construction formed from two pairs of substantially identical members. 
   
   
       14 . The base installation of  claim 10  wherein said enclosure contains an electrical box. 
   
   
       15 . The base installation of  claim 10  wherein said protective barrier has an access opening at opposed sides thereof. 
   
   
       16 . The base installation of  claim 10  wherein each pre-cast member has a rounded end portion integrally connecting with an extended side and a truncated side parallel to said extended side.
