Abstract
The invention relates to the setting 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.
Claims32
A vibrator for vibrating a bar, including a vibrator housing, means for vibrating said housing, and means associated with said housing for contacting said bar, said vibrator housing being adapted to seat over an end of the bar, a bore extending at least part way through said housing and is open to receive an end of the bar, and a plug is retained within the housing and wherein the bore is provided in the plug.
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, and a bore extends at least part way through said housing and is open to receive an end of the member, and wherein the member is a reinforcing bar and wherein a plug is retained within the housing and the bore is provided in said plug.
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.
