FIELD: construction.
SUBSTANCE: invention relates to window and door sliding blocks used for installation as windows, doors or partitions in building structures for various purposes, in particular, in residential premises. Sliding unit located between the floor and ceiling surfaces contains a movable block with sheet elements installed in a fixed frame, which contains an outer bowl and an inner bowl connected to each other by means of non-metallic frame inserts. Each bowl is provided with a support surface with a track profile installed on it, on which a longitudinal guide is fixed, and the movable block is made in the form of external and internal sash profiles fastened to sheet elements and interconnected by means of non-metallic inserts of the block, and is installed between the bowls of the fixed frame. Each sash profile is provided with supporting shelves interacting with the end surfaces of the sheet element, and limiting shelves interacting with the front surface of the sheet element and located on the side of the sheet element facing the bowl of the fixed frame. The movable block is equipped with roller bearings mounted on the longitudinal guides of the fixed frame, and the track profiles of the outer and inner bowls are interconnected by means of a non-metallic guide insert. The unit is equipped with a contact seal installed between the inner surface of the bowl and the outer surface of the bounding flange of the sash profile facing it, and the inner and outer bowls of the frame, as well as the limiting shelves of the sash profile of the block, have outer edges facing the center of the front surface of the sheet element and located along the edges of the leaf element. In this case, the distance "A" from the supporting surface of the bowl, located below the floor level, to the outer edge of the limiting shelf located along the floor surface, at least the outer sash profile of the block, does not exceed the distance "B" from the same supporting surface of the bowl to the outer edge the outer bowl of the frame, and the distance "B" does not exceed the distance "C" from the same supporting surface of the bowl to the floor surface.
EFFECT: increase in the resistance to heat transfer through a sliding assembly designed to provide the required strength and rigidity characteristics using metal structural elements with high heat transfer coefficients.
