ABSTRACT:
For power transmission between a wooden beam and another building component, for example another wooden beam, a blind bore and a vent bore opening into the bottom of the bore are formed in the wooden beam. An insert body is pushed into the blind bore. This body comprises two spaced end plates whose outer cross-section corresponds to the cross-section of the blind bore, and at least one, preferably four, power-transmitting bars whose ends are welded to the opposing sides of the end plates. Bar dowels are then driven in from the side of the wooden beam so as to penetrate spaces between adjacent power-transmitting bars. Epoxy resin is then pressed into the blind bore from the outside until the entire blind bore and preferably also part of the vent bore are filled in with resin. When the resin has hardened, the resin body and the steel parts form a composite body. Connecting members may be attached to the outer end part.
