Abstract
Form panel supporting walers (32, 34) are secured in crossed relationship by an assembly having inner and outer right angle-shaped members (10, 12) engageable with opposite sides of the walers, and clamp means to draw the members toward one another. The clamp means comprise a bar (18) fixed to one of the members (10) and extending slidably through the other of the members (12), and a wedge (24) extending through the bar (18) for engagement with said other member (12).
Claims11
An assembly for securing a pair of walers in crossed relationship, said assembly comprising:
- a first member having converging outwardly facing surfaces complementally engageable with the crossed walers to one side thereof, said outwardly facing surfaces of said first member defining a first angle therebetween;
- a bar secured to said first member and extending outwardly from the outwardly facing surfaces thereof;
- a second member received on said bar and having inwardly facing converging surfaces defining a second angle therebetween, said inwardly facing surfaces of the second member being complementally engageable with the crossed walers to the side thereof opposite said one side and said second member being movable relative to said bar to bring the outwardly facing surfaces of the first and second members into simultaneous engagement with opposite sides of the crossed walers, said first and second angles being essentially equal;
- and means to secure said second member to said bar to maintain the first and second members in such engagement.
An assembly for securing a pair of walers in crossed relationship to one another, said assembly comprising:
- a first member of right angle-shaped configuration having converging outwardly facing external surfaces complementally engageable with the crossed walers to one side thereof, said external surfaces defining a first angle therebetween;
- a flat bar fixedly secured to and extending from the external surfaces of the first member for passage between the walers;
- a second right angle-shaped member slidably received on the bar, said second member having converging inwardly facing surfaces defining a second angle therebetween, and inwardly facing surfaces of the second member being complementally engageable with the crossed walers to the side thereof opposite said one side, said first and second angles being essentially equal;
- and means to force said second member toward the first member.
An assembly for securing a pair of walers in crossed relationship to one another, said assembly comprising:
- a first angle-shaped member having converging outwardly facing surfaces complementally engageable with the crossed walers to one side thereof, said outwardly facing surfaces defining a first angle therebetween;
- a second angle-shaped member having inwardly facing converging surfaces defining a second angle therebetween, said inwardly facing surfaces of the second member being complementally engageable with the crossed walers to the side thereof opposite said one side, said first and second angles being essentially equal;
- and means to selectively draw the first and second members toward one another.
