Apparatus and method for construction of buildings to give the appearance of full log construction. Conventional wall studs are assembled in basically a conventional manner except that the corner is assembled in an "open" manner rather than the usual "closed" assembly, so that the corner studs form a V which opens toward the outside of the building. A corner block assembly, having been pre-assembled, is then inserted into this open corner. The corner block assembly extends vertically coextensive...

A tendon for prestressed concrete wherein inorganic particles are coated on an outer surface of a rod made of fiber reinforced plastic through a plastic adhesive layer. The inorganic particles are formed with minute rugged surface portions on the outer surface of the tendon for prestressed concrete, the rugged surface portions being firmly adhered to concrete. The inorganic particles are coated on the whole outer surface of the tendon for prestressed concrete, on the fixed portions at both ends,...

A corner piece for connecting adjacent hollow spacer members to form a spacer frame used in the construction of thermally insulated windows. The corner piece includes horizontal and vertical legs forming a right angle. One end of each leg has a cutting edge. When the ends of each leg are inserted into a hollow spacer which has internal partitions, the sharpened cutting edge is able to cut around the adjacent partition and thus enter the spacer fully. The corner piece is constructed in a manner w...

A profile consisting of two sections (1, 2) joined together. One section (1) is an open hollow section with an inner contour which is uniform with and somewhat bigger than the outer contour of the other section (2) and where the opening (4) is arranged so that two identical profiles can be telescoped into each other. According to the invention the other section (2) is solid or a closed hollow section. The opening (4) of the open hollow section (1), has a width which is somewhat bigger than the w...
