A kit for constructing scaffolding using pieces of lumber of standard sizes, comprising:
- a) a plurality of right angle brackets, each comprising a first hollow sleeve for slidably receiving a first piece of lumber and a second hollow sleeve secured at right angles to said first hollow sleeve for slidably receiving a second piece of lumber, a pin associated with each of said first and second hollow sleeves, said first and second hollow sleeves being each provided with a hole for receiving said pin;
- b) a plurality of base elements each comprising a third hollow sleeve for slidably receiving an end of a piece of lumber, a ground-engaging element connected to said third hollow sleeve, and a pin, wherein said third hollow sleeve is provided with a hole for receiving said pin;
- and
- c) a plurality of bracing elements for bracing against a vertical surface, each comprising a fourth hollow sleeve for slidably receiving an end of a piece of lumber, a surface-engaging element connected to said fourth hollow sleeve, and a pin, wherein said fourth hollow sleeve is provided with a hole for receiving said pin.
The kit for constructing scaffolding of claim 3 further comprising cotter pin means for securing each of said pins in said holes.
A right angle bracket for use in erection of scaffolding, wherein said scaffolding is erected using a plurality of lumber pieces of pre-determined standard cross-sectional dimensions, said bracket comprising a first hollow sleeve sized to slidably receive a first of said pieces of lumber, a second hollow sleeve secured at right angles to said first hollow sleeve for slidably receiving a second of said pieces of lumber, and a pin associated with each of said first and second hollow sleeves, said first and second hollow sleeves being each provided with a hole for receiving said pins.
