Lap beam connectors for allowing two beams to be joined together without having to use external fasteners such as screws. Each beam has at least one internal pair of receptacles for slidably receiving each end of a plate therein. The plate can be secured to inner walls of the beams by a crimping tool, and the like. The plate allows the weight of the beams and any structure being built to be distributed over the length of the beam instead of just being directly on the ends of the beams. The receptacles can be substantially U-shaped with triangular shaped sidewalls. Another part of the invention allows for attaching two U-shaped beam half sections together by having a nesting ledges/receptacles on at least one of the legs of one beam half sections. While the legs of each beam half overlapped against each other, the nesting ledges/receptacles hold the beam half legs to be held to fixed locations. Fasteners such as screws can be driven through the sides of the beam half legs to interlock the beam half sections to one another. An internal strap can be used to add strength to the beam which will allow the beam to span farther, while further securing beam half sections together.
