摘要:
The invention relates to a method and arrangement for installing an energy exchange unit (4) to a roof (2) of a building (1), and to an energy exchange element (3). In the arrangement the energy exchange unit (4) is supported on the roof trusses (10) in the installation area (5) such that bottom surface (31) of the energy exchange unit (4) is positioned between upper surface of the roof trusses (10) of the roof (2) and bottom surface of the battens (12) of the roof (2).

The present invention refers to joints between profile sheets (1) used for roofing, the joints being perpendicular to the roof ridge, and to providing support in the ridge direction for the profile sheets. The invention is based on providing the profile sheet (1) comprising, as viewed from above, a designed transverse profiling (7), with such a shape of the longitudinal profiling (4) at the lateral edges (2, 3) of the profile sheet (1), which enables overlapping profile sheets adjacent to each other in the ridge direction, in such a way, that the folds (12) of the longitudinal profiling (4) overlap only partly. Thus a larger effective width is achieved as well as an improved support in the ridge direction of adjacent profile sheets (1).

The invention relates to roofing that comprises two or more sandwich elements (2) that are tightly attached to each other and comprise a first sheet (4) forming an outer roof surface, a second sheet (6), and filling material (10) between the first and second sheets (4, 6). According to the invention, at least the first sheet (4) of the sandwich element (2) is furnished with water-proofing.

The invention relates to tubular piles encased in concrete, which comprise a metal pile tube (2) to be driven into soil, and in the upper end of the said tube an aperture for feeding liquid concrete mass into the pile tube interior (12). The lower end of the pile tube is provided with a pile shoe (1) comprising a longitudinal tip section (3) with uniform broadness and a ferrule (6), the maximum diameter (D1) of which is bigger than the outer diameter (D2) of the pile tube, and flow apertures (7), which are arranged above the lowermost upwards free base (24) of the ferrule and pass through the circumferential surface (23) of the said pile tube extension for the out-flow of concrete mass. The distance (L1) of the pile shoe from the tool tip (10) is at least five times the outer diameter (D2) of the pile tube.
