(54) CRSHYA-TERRACE

one

The invention relates to the construction, and more specifically to the design of the roof-terraces of residential and public buildings.

A roof terrace is known that contains supporting flooring, parsizolation, thermal insulation, multi-layer rolled carpet glued on cement sheath, and floor slabs laid on concrete posts supported on rolled carpet 1.

The main disadvantages of this roof are non-industrial, multi-functional, high cost, relatively short lifespan (as practice shows, its durability is no more than 5-10 years), useful and temporary loads are transferred directly to the roofing carpet, which leads to its premature wear, seasonality of execution of works.

The closest technical solution to the invention is a flat Kafi, a roof containing a ribbed support floor, a waterproofing carpet, floor slabs and a catchment tray, the floor plates being placed on parallel edges of the flooring precoated by bending the waterproofing carpet having 3 % slope in the direction of the catchment tray 2,

The disadvantages of this solution are also the laboriousness of the construction, the fragility of the roofing carpet, the transfer of the entire load directly to the waterproofing carpet, the seasonality of the work, as well as

About the complexity of the constructive solution of double water flow, on the floor slabs and partly along the channels-trays arranged under the floor slabs, for which catchment trays are made along

15 roofs in two Russ.

The purpose of the invention is to reduce labor consumption and increase the durability of the roof terrace.

This goal is achieved by

20 that in the roof terrace, containing supporting ribbed flooring, thermal insulation laid on the supporting floor, waterproofing, catchment tray and floor plates, floor plates are made with grooves for water drainage and placed on the longitudinal edges of the flooring, asbestos-cement waterproofing corrugated sheets located under the floor slabs on the transverse

30 fins of the flooring, yukushchikh razuyu height, providing a slope in the direction of the catchment tray.

FIG. Figure 1 shows reinforced concrete ribbed slab, total. Fig 2, a roof plan, (in the left part of the drawing shows the layout of the floor slabs, and in the right part - asbestos-cement corrugated sheets); in fig. 3 - section A-A; figure 4 - section bb in figure 2.

The roof terrace contains supporting plates of the coating, having longitudinal 1. And transverse 2 ribs, thermal insulation material 3, catchment tray 4, asbestos-cement corrugated sheets 5 and floor plates 6.

The roof terrace is made of prefabricated reinforced concrete slabs. The space between the longitudinal 1 and transverse 2 ribs is filled with insulating material 3, the thickness of which increases along the slope to the ridge. Then, asbestos-cement sheets 5 are placed on reinforced concrete slabs 4 and transverse ribs 2 providing 3% of the slope to the catchment trays 4. After this, floor slabs 6 are laid out on the longitudinal ribs 1. Thus, the rain and melt water seeps in through the grooves between the horizontally installed slabs of the floor, rolls onto asbestos cement corrugated sheets 5, then flows to the catchment trays 4 and is removed through the water intake devices 7.

The proposed construction in the roofs of terraces as a water-insulating layer to use unconventional. Material - asbestos cement, which has durability, biostability and low cost. Here, the need for a paroizolation, cement-bonding and gluing of a multi-layer roll roof is completely eliminated. In the described construction, asbestos cement sheets are protected from direct mechanical and atmospheric influences. The presence of a heat insulating layer of variable thickness allows a decrease in the thermal resistance of the roof in its lower parts, which eliminates icing in the direction of melt water and significantly reduces the asbestos cement roofing and uses it in operating roofs.

Due to the fact that asbestos cement sheets do not need special fastenings, but are loosely laid with a slight bias on the transverse fins of the slab, there are no obstacles to the free deformation of f asbestos cement sheets, usually due to the formation of cracks and lowering of the roof durability. In this construction, not only the underfloor space is ventilated, but also, and very importantly, the under-roofing layer through continuous air channels formed by waves of asbestos cement sheets. Such ventilation contributes to the intensive drying of the heat insulating material and the creation of a normal temperature and humidity regime and makes it possible to produce a device at different times of the year.

Thanks to the fact that the roof floor

0 is laid on the bearing flooring and more durable and relatively cheap materials are used, the durability of the whole structure is increased, and due to

From the design and increase of the assembly, the labor intensity is reduced by 50% and the cost by 25-30% compared with the known solution.
