(54) ROOFING WIRELESS COATING PLATE

one

The invention relates to building structures of coatings over industrial, public. and residential buildings.

The technical solution of slabs of coatings in the form of three-layer slabs is known based on the use of flat, large-sized asbestos cement sheets and various foams 1.

The disadvantages of this solution are the low carrying capacity of the slabs, the increased labor intensity and the cost of manufacturing the roof covering.

The closest in technical essence to the invention is the technical solution of the roofing non-roll bar covering, including the upper and lower supporting elements, the layer of thermal insulating material between them and the connecting parts. The upper and lower bearing elements are interconnected by means of wooden ffpycKOB. The upper and lower or one of the bearing elements can be made of flat, profiled sheets of slate, galvanized sheet or other materials. In construction, these plates are laid on pre-mounted metal or reinforced concrete girders.

located from each other no more than 4m 2.

The disadvantages of this solution are the increased complexity and cost of roofing, as well as their low carrying capacity, and therefore they are not used for overlapping large spans.

The aim of the invention is to reduce the laboriousness and cost of construction, as well as to expand the field of application of roofing non-roll slabs.

The goal is achieved by the fact that in a roofless wallless slab of a coating including upper and lower load-bearing elements, a layer of thermal insulation material between them 15 and fasteners, the pin is equipped with reinforced concrete ribs and anchors connecting the supporting elements with the fins, and the supporting elements are supported on reinforced concrete ribs with complete overlapping of the support surface of the latter, while the edges of the plate are curved.

FIG. 1–4 — two panels of each side of the plate are shown, section; in fig. 5 — slab-edge joint assembly; in fig. 6 - plate, longitudinal section. The roofing non-roll-over slab includes the upper slab 1, which serves as the roof, the lower slab 2, the thermal insulation layer between the slabs 3, connecting elements 4, reinforced concrete ribs 5 with reinforcement 6, anchor 7, connecting slabs 1 and 2 with ribs 5. Joints the slabs are overlapped with a splash 8. Initially, a three-layer slab with anchors 7 is made at the junctions with the ribs 5, then in the inverted form the NII with RSIRI U, OalCm D x-mch -...-l-he lay on the bottom of the formwork fittings and pallets are installed forming internal s side faces of the ribs, the ribs produced concreting. Other technological schemes for the manufacture of ribbed plates are also possible. The upper and lower plates can be made of corrugated or flat slate, of profiled tin, of rolled aluminum, of cement, of glass cement, of glass-reinforced plastics, of plywood or of other materials. Polystyrene, slag wool and various other materials can be used as thermal insulation between the plates. Such plates can be used for both planar coatings and curved surface coatings. Accordingly, they have straight or curved ribs. Depending on the span of the slab, as well as on the type of coating, they can be performed only with the contour, they can Dblil JJltinl IVJt / IDJXW IVVfi 1 J - "or with contour and intermediate edges. When plates are used for spatial coatings, diagonal ribs can also be arranged in them. The solidity of the combination of a three-layer slab with a reinforced concrete edge is achieved by the adhesion of hardening concrete to the material of the slab by releasing anchor bolts from the slab into the ribs. To increase adhesion, the bottom plate surface may have a special groove. Anchor bolts can be simply embedded in the ribs. This is possible when anchor bolts are passed through special tubes laid in the ribs. The plate is pressed against the rib with the help of nuts that are screwed onto the bolts. This invention allows overlapping large spans with roofless slabs. In this case, can not replace reinforced concrete slabs. Three-layer slabs with reinforced ribs are considerably lighter than conventional reinforced concrete slabs, which allows for a reduction in the consumption of steel for the installation of coatings. In this case, there is no need to perform work on the construction site on the device of thermal insulation of the coating, according to the way f J, .. -, about the leveling tie and the device of the roofing roof. The economic effect from the use of a roofless non-roll three-layer slab with reinforced concrete fins is determined by the reduction in the labor intensity of construction work and the reduction in the consumption of steel and concrete.
