Abstract
Ladder frames for shoring structures are assembled into towers using cross-braces clamped to the columns of the frames. The towers several tiers high are braced one to another by secondary braces, also clamped to the columns of the frames. Disclosed is a connector that permits two secondary braces to be joined to the column at a single location. The connector is such that one secondary brace is set to lie horizontally, whereas the other may lie diagonally. The connector includes bands which may be clamped and tightened onto the columns and braces, and the tightening means is not detachable from the connector; clamping wedges and bolts are provided which are all captive.
Claims10
Connector for shoring structures and the like, comprising:
- a first band, arranged in two parts which are pivotedly connected to be movable to allow the band to be fitted onto and around a vertical column;
- a first means for tightening the two parts of the first band together so that the band grips the column;
- a second band, secured to the first band, and arranged in two parts that are movable to allow the second band to be fitted onto and around a first brace of smaller section than the column;
- a second means for tightening the two parts of the second band together so that the second band grips the first brace independently of the means for tightening the first band;
- a third band, secured to the first band independently of the second band, and arranged in two parts that are movable to allow the third band to be fitted onto and around a further brace of smaller section than the column;
- and
- a third means for tightening the two parts of the third band together so that the third band grips the further brace, independently of the first means for tightening the first band, and independently of the second means for tightening the second band;
- said second and third bands are positioned on opposite sides of the pivotal connection
- wherein said second band is spaced, in the circumferential sense relative to the column, at right angles to the said third band;
- wherein said second and third bands are each at substantially the same height, relative to said first band;
- and wherein the axis of the column and the axis of said first brace are spaced slightly apart from each other at right angles to each other when viewed from above, and wherein the axis of the column and the axis of said further brace are space slightly apart from each other at right angles to each other when viewed from above;
- whereby said column and said first and further braces may be placed with their respective axes all mutually perpendicular one to another, when viewed from above along the axis of said column, and said axes substantially intersect one another at said connector.
