Prefabricated element of perimeter masonry, particularly for dry stone walling

摘要

In the present invention, there is disclosed a prefabricated element of perimeter masonry, particularly for dry stone walling and with preserved possibility to make additionally a monolith therefrom by a sealing compound wherein the invented element is made of exactly cast supporting sections (1) having the form of rectangular slabs with a system of vertical cavities performed in the interspace thereof consisting of at least single-row system of bottle-shape cavities formed by cast PET bottles (2). Distribution of the PET bottles (2) is identical in each the prefabricated element used, whereby the PET bottle (2) necks are oriented in the same direction. Both bottoms and necks of the PET bottles (2) are in contact with upper, respectively lower wall of the prefabricated element and therefore the height module of the prefabricated element corresponds to the height of the used PET bottles (2). Horizontal channels (3) having the form of grooves are performed along face walls on the side of the PET bottle (2) necks between the rows of the vertical cavities. In extension of the longitudinal axial plane of at least one PET bottle (2) row, the first lateral contact wall (7) of the prefabricated element is provided with a vertical locking groove (8) and the other lateral contact wall (9) is provided with a locking camber (10). Said locking camber (10) has at its top portions a cylindrical shape that is coaxial with the nearest cast PET bottle (2). The width of the locking groove (8) in the first lateral contact wall (7) is greater than the width of the corresponding locking camber (10) in the other lateral contact wall (9) of the adjacent prefabricated element. After horizontal pressing of the adjacent prefabricated element, these differences in shape form a system of vertical channels (4) in which enter the horizontal channels (3). The size of the locking groove (8) and that of the locking cambers (10) and their distance from longitudinal axes of the neighboring PET bottles (2) are determined so that when horizontal pressure is applied to the adjacent prefabricated elements the mutual position of the internal vertical bottle-shaped cavities is identical with the mutual position of the vertical cavities of the prefabricated element disposed ane above other.
