Abstract

The purpose of the invention is to provide a double-skinned design the roofs on a very rugged layout, where known methods cannot be performed with great savings in building materials, energy and laboriousness. This is achieved by the roof of which the upper shell is formed by plates mounted on a supporting spatial structure formed by * bar elements whose height is at least from the perimeter of the building decreases towards the roof the gullies, the plates consisting of at least three bars spaced apart apart in one "area to which they are the filling elements are deformable joints and boards are formed into the top surface of the top roof mantle.

Description

The invention relates to a double-skin roof, pronouns for residential buildings.

Previously known flat roof designs on residential buildings have the greatest number of defects compared to other parts of the building, especially in the field of thermal and waterproofing technology. · In the first case, the user complains about cold and unfavorable comfort in the roofs; surface condensation, etc., which usually leads to serious hygienic and aesthetic defects, if not damages directly. that lay on the roof slope on a pair of longitudinal reinforced concrete beams placed on the top floor ceiling panels and in the middle place the panels on the roof gutter · However, this system can only be used for single rectangular roofs I have floor plans that have few penetrations, where it is possible to set up a roof gutter and therefore for most roofs / unusual. This deficiency is trying to solve the double-skin roof of the second type so that the ceiling of the last floor is fitted with rectified

welded nuts on one end and supporting flanges on the other, which are pushed onto the shank of the bolt, which is welded to the steel foot, which is connected to the other foot by stirrups made of reinforcing steel. on them at corners ·

To prevent corrosion and to ensure stiffness of the supports, the steel structure is concreted to the height of the welded feet · This system eliminates the deficiency of the first system, but is too laborious both in the production of steel supports and steel consumption ·

The above-mentioned drawbacks and disadvantages are eliminated by the two-floor Roof / Λnames for residential buildings _? the upper shell of which is formed by slabs arranged on a supporting spatial structure, formed by rod elements »whose height ae at least from the perimeter of the building decreases towards the roof drain, the essence of which is» deformed elm plates consist of at least three bars spaced apart one baldness of the game roof cladding »to which are the infill elements attached? the boards are deformed with other joints and the boards are formed into the shape of the upper surface of the upper roof cladding * with a waterproofing layer on the side of the infill facing away from the molding »

The advantages of the double-walled roof according to the invention lie mainly in the fact that it allows to make double-walled roofs at extremely low frequency of prefabricated elements on very rugged ground plans - where known methods cannot be carried out. removes completely concrete roof gutters »pairs of reinforced concrete beams, rectifying steel supports | and thus a lot of labor / production both during production and assembly, but also high demands on scarce building materials and energy ·

An exemplary embodiment of a double-skin roof according to the invention is shown schematically in the attached drawing, wherein Figs. 1 and 2 show axonometric views of the roofs; Figs. 3,4,5 and 6 are views of deformable slabs; Figs. 7, 8, 11 and 12 transverse vertical panel sections before installation on the roof structure and figs · 9, 10, 13 after installation on the roof structure ·

According to the illustration, the two-pane roof for residential buildings consists of wooden rods 2 and J whose height decreases from the periphery towards the roof outlet 3. According to Fig. 1, the rods 2 are fastened directly to the ceiling structure J and according to ebr · 2 are bar elements J maturing on supports J5 t> * whose height decreases towards the roof outlet being attached thereto elastic plate £, which pe attachment you the officials / warped ruled surfaces 2 »j * ⁿ ^ are provided with at least one the waterproofing layer J and, if necessary, the penetration 8, wherein the roof perimeter is formed by elements 11 with vent holes 10 and the bar elements 2 are interspersed by spacers Γ2 and the bar elements J are braced with rods 13 and

In accordance with FIGS. 3, 4, 7, 8, 9 and 10, the boards 80 are attached to the strips 44, as shown in FIG. 5, 6, 11, 12 and 13, boards 16 are fastened to the strips 14 and are provided with a waterproofing layer.
