According to Patent Description No. 178256, there is a frame known, made of metal sections used for production of fireproof front windows and doors or glazed roofs characterised by having protective panels or other profiles made of heat-absorbing hydrophilic material of a high water content, or panels or other profiles comprising some heat-absorbing hydrophilic material of a high water content, installed on the internal and/or external surfaces of aluminium sections.

Set of frame and wing sections and elements in fireproof construction according to the invention consists of two kinds of shell-like sections set alternately : one section of a given shape in a frame and a wing. Frame sections of different shapes are bound together with thermic separators and an outside profile cover plate through rivets, while on the other side they are bound with a heat-expanding element set on the thermic separator and frame sections.

Elements that cool the sections are set in spaces between them. Heat- expanding elements that press the cooling elements against section walls are set in the cavities between internal projections of thermic separators. A wing consists of sections of varied shapes bound together with thermic separators where a heat-expanding element is set on the external surface and on the internal side sections are connected with the binding wall by a rivet and a screw. A fireproof pane, fixed with pane-holding laths with gaskets, is set in the space between sections and ceramic plates. A heat-expanding element is placed between the fireproof pane and the wall that binds sections from inside while gaskets are set in C-shaped cavities at the section ends and cooling elements are set in the sections. The sections, the profile cover plate, the angle section binding wall and thermic separators are permanently joined while other elements are freely set in the space they occupy. The profile cover plate, the binding wall and angle sections are made of infusible material.

The advantage of the aforementioned solution consists in providing the required insulation of a given room from the other part of a building in case of fire and a possibility of using sections, insulation profiles, ceramic plates and thermic separators of repeatable shapes both for frame and wing construction.

The object of the invention is presented as the example product in the drawing, where Fig. 1 shows a set of frame and wing sections and elements in fireproof construction presented in cross section of the frame and wing.

A set of frame sections in fireproof construction according to the invention consists of sections 1 and 2 of varied shapes bound together with thermic separators 3 and with externally binding profile cover plate 4 through a rivet 5. A heat-expanding element 6 is set on the other side, on the thermic separator 3 and on frame sections 1 and 2; section cooling elements 8 are set between thermic separators 3 and in frame sections 1 and 2 while heat- expanding elements 9 that press the cooling elements 8 against walls of sections 1 and 2 are set in cavities 7 between internal projections of thermic separators 3. The wing consists of sections 1'and 2'of varied shapes bound together with thermic separators 3'with a heat-expanding element 6'set on the external surface. From the internal side, sections 1'and 2'are connected with a binding wall 10'by a rivet 5'and a screw 11. A fireproof pane 14, fixed with pane-holding laths 15 with gaskets 16, is set in the space between angle sections 12 and ceramic plates 13. A heat-expanding element 17, which closes the space between the fireproof pane 14 and the binding wall 10, is placed between the fireproof pane 14 and the wall 10 that binds sections 1 and 2 from inside. Gaskets 19 are set opposite each other in C-shaped cavities 18 at the ends of sections 1 and 1'. Cooling elements 20 and 20'are set in the sections 1, 1', 2 and 2'. The sections 1, 1', 2 and 2', the profile cover plate 4, the binding wall 10, angle sections 12, as well as thermic separators 3 and 3'are permanently joined together while other elements are freely set in the space they occupy. The profile cover plate 4, the binding wall 10 and angle sections 12 are made of infusible material.

In case of fire the method of operation of the set of fireproof wall sections and elements consists in the fact that under the influence of heat affecting the set surface, the elements 6, 6', 9 and 17 expand their volume filling up the space they occupy and sealing it. The cooling elements 8 and 8'and 2 and 2' cool down the walls of sections 1, 1', 2 and 2'.
