Two-stage joints protection system for a water-tight buildings

摘要

Two-stage joints protection system for a water-tight buildings,trench for sealing joints (7) between the prefabricated concrete parts (6), as well as for the joints behind the barrel protection and for additional protection of the sealed with them, joints (7) against external influences,characterized bya flat joints protection profile (1) made from an elastic plastic, on one side with an average over the entire length of the joints protection profile (1) and running to the underside of open, rectangular recess (2), wherein the center of the recess (2) a wedge-shaped recess as a bending notch (3) is formed, and wherein the thickness of the joints protection profile (1) of a wedge shape to the two outer sides (5) and reduced towards the underside of the two outer sides (5) of the joints protection profile (1) is formed to be flat and on the two outer edges of the joints protection profile (1) downwardly projecting, wedge-shaped closure strips (4) are formed, whereby to the underside of the joints protection profile (1) a flat profile trough (14) is formed to closely - and adhesive composition (11) is filled to be flat, and thus a ready-to-assemble joints for sealing element (15) is produced, for example, and as a result of which the central recess (2) of the joints protection profile (1) with the application of the tightly - and adhesive composition (11) a joints for sealing profile (9) is formed and to the adjoining outer edges in each case a joints behind the barrel protection strips (10) is formed, to the underside of the joints protection profile (1), on the applied tightly - and adhesive composition (11) at the outer edges by means of the wedge-shaped closure strips (4) is limited, an air - and moisture-proof sealing foil (12) is mounted, and wherein for storage and transport of the joints for sealing elements (15),this in the required lengths are made and in air - and moisture-tight foils or foil hoses are packaged and / or welded, so that a transport - and the use of a finished joints for sealing element (15) is produced, which in the case of the assembly, only on the joint to be sealed (7) has to be pressed, and wherein during the mounting on the construction site for the joints to the protection profile (1) surfaces which come to rest on the joint flanks of the precast concrete elements (6) a treatment with a promoter of the coating is carried out, and then the joints for sealing element (15) with the applied to the underside of the tightly - and adhesive composition (11) on the side of the medium to be sealed and to be flat filled joint (7) of the precast concrete elements (6) is applied and is pressed by means of which, in the joint to be sealed (7) which in the downwardly open recess (2) of the joints protection profile (1) of the joints, which is formed a sealing profile (9) on the upper side of the joint to be sealed (7) is pressed, and in which at both sides of the joints formed a sealing profile (9), on the upper side of the precast concrete elements (6), joints behind the barrel protection strips (10) are formed and wherein at the abutting edges of the joints protection profile (1) for protection against moisture by the sealing strips of plastic can be adhesively bonded, which on both sides of the butt joints at least 5 cm, and wherein during the application of the joints for sealing element (15) in the case of an angular gap (7), mounted between the horizontal prefabricated concrete parts (6) or a base plate (8) and then abutting, vertically disposed prefabricated concrete parts (6), a bead-like strips a tightly - and adhesive composition (11) on the angular gap (7) is applied, whereby, when the application of the joints protection profile (1) on the angular floor joint (7) a groove (13) is formed.
