Abstract: The invention relates to a room cell for use in the modular construction of buildings, which comprises a base plate and side walls enclosing a usable interior space, wherein the load-bearing components of some and preferably all side walls are formed by panels of cross-laminated timber, wherein the room cell comprises a duct for accommodating cables and pipes passing through the room cell from top to bottom, wherein the duct is confined on its bottom by a duct floor or on its top by a duct ceiling, and wherein the duct floor or the duct ceiling comprise a step projecting upwards or downwards, respectively, into the duct.

Abstract: A method of manufacturing wall elements for buildings, cross laminated timber panels of a specific width and length stocks in a store, and the panels are sawed up transversely to the longitudinal direction to obtain cross laminated timber panels of the same width and smaller length. A plurality of panels are placed onto a conveying track transversely to the direction of running, and indeed such that the panels are flush at the top and bottom and the side edges of consecutive panels contact one another. The panels on the conveying track are connected along the contacting longitudinal sides to form a cross laminated timber apron. The apron is sawed up transversely to the direction of running of the conveying track to obtain cross laminated timber boards of a defined width.

Abstract: A module for use in the erection of buildings in modular construction has a parallelepiped-shaped basic design and has outer walls, a floor, and a ceiling, with the supporting components of some, and preferably all, of the outer walls being cross laminated timber boards. The module includes a useful area and at least two separate vertical ducts, with both vertical ducts running through the module from bottom to top and each being included between at least one outer wall and at least one duct wall.
