Abstract In order to create a service girder intended for use in the field of application of the conventional squared timbers and usable for such tasks, having dimensions in the range of approximately 10 to 20 cm in height, which is more econ- omical in use, after consideration of all the important practical aspects, than the formerly used squared timbers, a service girder of wood, which is connected with an upper flange and a lower flange and a flat solid web linking these two flanges which is linked to the flanges by a plu- rality of tongues engaging in said flanges and bonded over the entire length of said girder, wherein the web consists of plywood or of a plate of three wooden layers bonded to- gether and wherein the wood fibers of the outer layers run perpendicularly to the fibers of the center layer, and the flanges are in each case composed of several wooden layers, of which the wood fibers extend substantially in the longi- tudinal direction of the girder, is further developed in such a way that each flange (1, 2) consists of at least three wooden layers (5, 6, 7) and the wood fibers (F5, F6, F7) of each adjacent ?ir of wooden layers are mutually inclined at an angle of about 10° to 15°.
