Abstract

A kit for assembling timbers into a play structure is disclosed. The kit includes a frame bracket which has a frame segment joined at a right angle to a beam segment. The frame segment has four nail or screw holes and the beam segment has two nail or screw holes. The beam segment has a square bolt hole for receiving a carriage bolt. The frame segment is adapted to joining two timbers into an A-frame so formed to a transverse overhead laminated beam. The kit also has a frame brace with a body plate having a flange joined to it at such an angle that when the body is placed flat on the A-frame, the flange lies flat on the beam. The frame brace has nail or screw holes and bolt holes in both the body and the flange. The kit also contains rectangular flat beam clamps adapted to attachment across the laminations of the beam so as to restrict the separating of the laminations. The beam clamps have at least two nail holes and a central bolt hole. The bolt hole being circular on the beam clamp for use with the frame bracket and oblong for use with a swing hanger.
