Abstract
The invention relates to the of poured concrete and the need to avoid air pockets and voids within the setting slurry. At least one reinforcing rod, and preferably a grid of rods, is embedded in the poured concrete. The setting slurry is vibrated by vibrating the rod or grid. A vibrator receives the protruding end of the rod and is vibrated to vibrate the rod.
Claims79
For vibrating a bar, a vibrator including a vibrator housing, means for vibrating said housing, and means associated with said housing for contacting said bar.
A vibrator as claimed in claimed 10, wherein the securing elements are bolts.
A vibrator including a vibrator unit, a housing coupled to said unit, and means within said housing for engaging a member to be vibrated whereby vibrations from said vibrator unit may be transmitted to said member.
A vibrator including a casing, vibration inducing means within said casing, a housing secured to said casing to be vibrated thereby and means within said housing for engaging and vibrating a member.
A vibrator including an elongated casing, a shaft extending longitudinally within said casing for rotation therein, an eccentric weight associated with said shaft for rotation thereby to create vibrations, a housing secured to said casing, and a plug secured within said housing and having at least one bore arranged to receive one end of a bar.
A vibrator including a casing, a rotatable eccentric within said casing, a housing secured to said casing, a plug secured within said housing, said plug having at least one bore extending at least partially therethrough and dimensioned to receive one end of a reinforcing bar whereby vibration created by rotation of said eccentric will be transmitted to said reinforcing bar.
A method of vibrating a member including the steps of placing a vibrator in contact with said member and vibrating said vibrator to vibrate said member.
A method of vibrating a bar including the steps of seating one end of said bar in a housing and vibrating said housing to impart vibrations said bar.
A method of setting concrete including the steps of providing at least one reinforcing bar, pouring wet concrete around said bar at least partially to embed said bar, seating a protruding end of said bar in a vibrator housing, and vibrating said vibrator housing to impart vibrations to said at least partially embedded bar.
