Claims

(54) REINFORCED CONCRETE PANEL OF THE COVERING The invention relates to the construction, in particular to the construction of the panel covering the building or construction of full factory readiness. Ferro-concrete prestressed TT-type coating panels of a length of 12 and 15 m are known in construction. The disadvantage of such a coating is that under construction conditions laying of insulation and waterproofing is performed. In addition, these panels do not have ribs on the slab shelf, providing drainage organization. Closest to the present invention is an H-shaped reinforced concrete covering panel, including longitudinal beams, integrally joined by a slab, and a heater 21. The disadvantage of this construction is that the insulation is located on the slab on top and for waterproofing the panel it is necessary to perform work on the installation of an additional layer of plating. In this case, the manufacture of the panel requires additional labor costs for laying insulation, waterproofing, and an increased consumption of materials for asbestos cement sheathing. The purpose of the invention is to simplify manufacture and increase industrial output while reducing material intensity. This goal is achieved by the fact that a reinforced concrete H-shaped covering panel, including longitudinal beams, integrally joined by a slab, and insulation, the panel is equipped with a sleeve of profiled sheets, in which the insulation is enclosed, while the insulation is located on one side of the plate, the ends of the sleeve are monolithic in the longitudinal beams, and one of the profiled sheets - in the slab. FIG. Figure 1 shows schematically the cover panel, top view; in fig. 2 section B-B Ia FIG. one; in fig. 3 and 4, sections A-A and B-B in FIG. one; in fig. 6 joint of two panels. 392 The panel includes longitudinal prestressed beams 1 combined by a connecting slab 2. The longitudinal beams together form a H-shaped joint with a connecting plate. Under the bonding plate there is a holder 3 of metal profiled sheets 4 and 5, between which a thermal insulating element 6 is placed. The holder is recessed into longitudinal ribs. In this case, the metal sheet 4 is connected to the bonding plate, and the metal profiled sheet 5 is supported at the longitudinal base and carries insulation, for example, foam polystyrene. At first, longitudinal beams are molded to the installation level of the cage with thermal insulation, then the cage is placed on the mold cess and the concreting is continued until the panel is fully ready. To prevent the insulation from being saturated with moisture during concreting, the longitudinal edges of the sleeve are wrapped with sealing tape. The coating panel is made of concrete mixed on strong aggregates. Portland cement M-500 is recommended as a mortar. The plate has a technological bias 1; 100 for the discharge of precipitation. On top of the slab, on the two sides, in the longitudinal direction, the upper part of the longitudinal beams 7 is molded, intended to improve the drainage and. high-quality waterproofing of the joint, which is carried out in construction. Roof panels are mounted with a gap of 8 between the longitudinal edges. 4 After concreting the stitches on the upper edges of the longitudinal edges of the panel, in order to seal the joint, tape 9 is glued (four layers of tape in two rows with an overlap). Thermal analysis of the coating panel revealed a favorable temperature distribution on the surface of the plate. Reinforced concrete insulated non-roll-out H-shaped panel has a high degree of prefabrication, can be used on the construction site as a finished product, which does not require any additional operations, except for sealing joints. Invention Reinforced concrete H-shaped cover panel, including longitudinal beams, integrally joined by a slab, and insulation, which, in order to simplify the manufacturing and control of industry, while reducing material intensity, the panel is equipped with a clip of profiled sheets, in which insulation, while insulation is located on one side of the slab, the ends of the cage are embedded in the longitudinal beams, and one of the profiled sheets is in the slab.
