Concrete Columns
EFCO-FORMS WITH SVRLS-4000 HIGH FREQUENCY VIBRATORS
|
JOB SITE:
Renovation of bridge
columns on Rt. 95 Conn
PROBLEM: Internal vibrators would not reach bottom of column due to reinforcement bars. SOLUTION: Model SVRLS-4000 (Page 6) was recommended. VIBCO designed a special bracket to be attached to the EFCO form and fit between two horizontal stiffeners. When loosening the clamping bolts it could be removed and moved up the form as the pour progressed. A total of B vibrators were used ? one on each side. vibrators were started when the concrete reached them and continued until it reached the next group of vibrators 6? up. They were then stopped and moved 6? above top row of vibrators. Vibration time approx. 5 mm. Concrete was trucked in from local ready mixed plant. (6? slump) RESULT: Columns came out perfect. The customers word was - "They look just like marble..." |
