Abstract: A masonry wall is provided with a plurality of passageways. At least one reinforcement member is provided in each of the passageways. The reinforcement members include a first group of reinforcement members each having a centre line on the first side of a midplane of the wall and a second group of reinforcement members each having a centre line on the second side of the midplane. The passageways include slots that are open horizontally to the first side of the wall only. The second group of reinforcement members are arranged in passageways located spaced from the second wall surface opposite of the first wall surface. The reinforcement members in the passageways are each embedded in an adhesive substance bonded to the reinforcement members and to an inner surface of the passageway in which the reinforcement member is provided.

Abstract: A floor assembly comprising at least one plate, at least one girder connected to said plate, which girder is provided with at least one passage extending transversely to the girder and which supports at least one removable panel. The floor assembly further comprises at least one section supported by at least one girder, which section extends in a direction transversely to the girder. Said section comprises a separating segment and first and second supports located on either side of said separating segment, wherein said first and said second support are located at different heights relative to an upper side of the separating segment. The first support supports the panel, whilst the second support supports a stonelike floor. The second support is located near a bottom side of the separating segment remote from the upper side.

Abstract: The invention relates to a concrete lining element for a drilled tunnel, which element is formed as a ring segment and is internally reinforced, and a plurality of which ring segments can be joined together to form a ring, and a plurality of rings can be joined to form the lining for the drilled tunnel and wherein, in order to couple adjacent rings at the intermediate ring joint, each element is provided at one side bordering the ring joint with at least one projection, and at the opposed side with a corresponding recess to admit the projection of an adjacent element. The height of the projection, respectively the depth of the recess on the respective side is between 30 and 60 mm, and the projection, respectively the recess at the transition from its top, respectively its bottom to its side walls, possesses rounded comers, having a radius of rounding of between 5 and 50 mm.
