Bed base rescrewed

The screws on one side of the bed frame have all come out, so the base with slats is no longer attached to the bed fram itself. Its a weird bed, its like the slats are in a box and the box screws into the frame. Additionally, part of the box part has snapped and would need to be connected back together somehow, with maybe a bracket or something? This is the part that needs to be screwed into the frame, so something to support the structural integrity is important
