Construction made of individual parts whereby the individual parts are at least partly made of wood-concrete-composites (100, 200, 300, 400, 500, 600, 701, 702, 703, 760, 770, 801, 802, 803, 860, 870, 910, 920, 930, 940, 950, 960, 970, 980, 1030, 1031, 1032, 1033, 1034, 1035, 1100) made up of at least one wooden construction part (110, 773, 873, 912, 922, 943, 952, 982, 1110. 210, 310, 311, 962, 963, 972, 973, 974) with a wood cross section (410, 510, 610, 721, 722, 723, 762, 821, 822, 823, 872) and a concrete construction part (101, 201, 202, 911, 921, 941, 942, 943, 981, 871, 1120, 301, 961, 971) with a concrete cross section (420, 520, 620, 711, 712, 713, 811, 812, 813, 861). Whereby the wood-concrete-composite elements are at least partly prefabricated and then assembled in the factory or later on the construction site. and are characterised by the fact that the connections or couplings (641, 642) of the individual construction parts with each other and /or with other construction parts are provided with a force fit through the transmission of forces via the concrete cross section (520, 771, 871), whereby there is a transmission of forces between each of the wood cross sections and the concrete cross sections to absorb vertical forces, and the transmission of forces is provided essentially in the end part of the wood cross section whereby the transmission of forces occurs solely via the concrete cross section by means of steel moulded parts that are anchored in the concrete and screwed into the wood or occurs solely via the concrete cross section by means of steel moulded parts, which are slit and glued into the wood and anchored in the concrete or occurs partially via the wood cross section as well as the concrete cross section by means of at least one perforated steel plate, which is slit and glued into the end-grain, whereby the load point at the front end is introduced by, for example, at least one perforated steel plate, which is slit and glued into the end-grain, whereby the combined effect is produced by means of expanded metals (432, 433) that are slit and glued or occurs partially via the concrete cross section and partially via the wood cross section by means of corresponding cut-outs in the wall-side concrete plate, into which the wood beam cross sections protrude or occurs partially via the concrete cross section and partially via the wood cross section by means of a joist hanger in the wall-side head beam orcan occur solely via the wood cross section through a choice of either the underside, front end or combination of these, whereby the corresponding force coupling in the form of reinforcement steel, which is glued into the wood at the end of the concrete cross section, enables a force to be transmitted with the wood cross section or is transferred solely via the concrete cross section and can occur either on the underside and/or front end, whereby a corresponding suspension mounting in the form of a nail plate, which is pressed into and glued onto both sides of the wood cross section, or steel moulded parts, which are screwed onto the wood and anchored in the concrete, or steel moulded parts, which are slit and glued into the wood and anchored in the concrete, enables a force to be transmitted from the wood cross section into the concrete cross section.
