Ornamental Concrete Columns
|
PROBLEM: Internal rebars made it difficult to use internal vibrators and the form was also too tall for internal vibrators to reach bottom. The columns came out with large voids and unvibrated surfaces. SOLUTION: Contractor had large compressor on job site and 2 pneumatic model SVRLS 4000 high frequency vibrators were recommended mounted on a clamp-on bracket with a lug bracket. Lug-bracket was chosen so that contractor could move the same vibrators to other permanently mounted lug brackets on his wall forms. Vibrators were mounted 2? from bottom and 7? from bottom then moved 5 each time. Vibrators were stared when concrete reached them and stopped when concrete reached the opposite higher vibrator which then was started. RESULT: Excellent surface finish was achieved without any rework. Concrete completely consolidated. |
