When laying foundations with the aid of pillars (10) driven into the ground, a collar (12) is placed around each pillar (10) at a predetermined distance from the pillar's (10) upper end (11). A hat (13) is then put on the pillar, which on its top has an opening (14) and in its base a recess (15), connected to the opening (14). The recess (15) is so dimensioned that there is space between the periphery of the pillar and the sides of the recess (15) and between the end surface (11) of the pillar and the bottom (16) of the recess; the hat is then placed on the end of the pillar with its base resting against the collar (12). After placing a beam (17, 18) on the hat (13), concrete is injected through an opening (19) which goes through the beam (17, 18) and is arranged to be above the centre of the hat's opening (14), so that the said spaces and openings are filled with concrete, whereby beam (17, 18), hat (13) and pillar (10) are connected rationally and at low cost.<IMAGE> |
