Description

Изобретение относитс к строительству , а именно к конструкции солнцезащитных устройств.The invention relates to the construction, in particular to the construction of sun-protection devices.

Известно солнцезащитное устройство , содержащее оконную коробку, на внешней стороне которой расположен поворотный экран 1.Known sunscreen device containing a window box, on the outer side of which is a rotating screen 1.

Недостаток известного устройства заключаетс в его низкой эффективности солнцезащиты и незначительной циркул ции воздушных потоков.A disadvantage of the known device lies in its low efficiency of the sun shade and insignificant circulation of air currents.

Целью изобретени вл етс повышение эффективности солнцезащиты светопроема и улучшение циркул ции воздушных потоков.The aim of the invention is to increase the efficiency of the sun shine of the aperture and to improve the circulation of air currents.

Поставленна цель достигаетс тем, что оконна коробка выполнена по периметру с выступом, а поворотный экран выполнен из светопрозрачных покрытых солнцезащитной пленкой пластин, шарнирно прикрепленных к выступу, при этом суммарна площадь пластин соответствует площади оконного проема.The goal is achieved by the fact that the window box is made around the perimeter with a protrusion, and the pivoting screen is made of translucent sun-coated plates hinged to the protrusion, with the total area of the plates corresponding to the area of the window opening.

На фиг. 1-3 изображена оконна коробка с поворотным экраном в трех проекци х; фиг. 4 - фрагмент фасада здани .FIG. 1-3 shows a window box with a rotating screen in three projections; FIG. 4 - fragment of the facade of the building.

Солнцезащитное устройство включает оконную коробку 1 с двойным остеклением 2, выступ 3, поворотный экран 4.The sun protection device includes a window box 1 with double glazing 2, a ledge 3, a pivoting screen 4.

Оконную коробку 1 с прикреплент ным в ней выступом 3 устанавливают в светопроем стены здани 5. Выступ 3 выполнен по периметру окон ого проема и выходит за пределы плоскости стены здани .По кра м выступа 3 шарнирно по горизонтальной оси вращени установ10 лен поворотный экран 4 из прозрачных, покрытых солнцезащитной пленкой пластин .A window box 1 with a protrusion 3 attached thereto is installed in the light-opening of the walls of the building 5. The protrusion 3 is made around the perimeter of the window opening and extends beyond the plane of the wall of the building. At the edge of the protrusion 3, a pivoting screen 4 of transparent covered with sunscreen plates.

Поворотный экран 4 может состо ть Swivel screen 4 may consist

15 из 2-х или более пластин, причем их суммарна площадь соответствует площади оконного проема.15 of 2 or more plates, and their total area corresponds to the area of the window opening.

Обрамл ющий по контуру оконную коробку 1 выступ 3 обеспечивает за20 тенение светопроема от пр мых солнечных лучей и служит основой дл креплени светопрозрачного солнцезащитного экрана, а также дл креплени сплошного непрозрачного экрана 6 The contour-framing window box 1 of the protrusion 3 provides for obstruction of the light aperture from direct sunlight and serves as the basis for mounting the translucent sunscreen, as well as for attaching a solid opaque screen 6

25 дл солнцезащиты стен. Выступ 3 может быть выполнен, например, из железобетона , а также из дерева, металла или пластмассы.25 for wall shading. The protrusion 3 can be made, for example, of reinforced concrete, as well as wood, metal or plastic.

Claims

30 s-pedaling way. During the daytime in summer, the pivoting screen 4 is set to the position / shown in FIG. 1. The falling sun rays are reflected from the outer surface of the plates of the screen 4. The sun irradiated part of the plate partially heats up, thus forming a temperature difference between the shadow screen and the surface-irradiated plate of the screen 4. As a result, an uneven heating of the air near them occurs, thus occurs around the plates screen 4. the movement of air, as the more heated air tends to rise upwards, and the cold one moves downward. The movement of the air flow removes part of the heat from the outer surface of the glazing of the window box 1 and reduces its heating temperature. Consequently, the transparent glass plates of the screen 4 operate in the summer as a sunscreen for the light aperture, exclude direct sunlight from entering the light aperture, and create convective air flows that remove heat from the outer glazing surface of the window box 1 even in the absence of wind. In this case, with an increase in the number of plates of the screen 4, the effect of convective heat removal increases. In the cold season, for example, in winter, the front screen 4 is set to the position shown in FIG. 2 (left) - strictly vertically, forming a closed air gap between the plates of the screen 4, the glazing 2 of the window box 1 and the protrusion 3. Thus, the heat absorbing plates of the screen provide additional heat influx by radiation through the air gap between it and the glazing. In addition, a translucent screen of heat-proof glass plates with an air gap and double glazing is a multi-layered external fence with sufficient heat transfer resistance equal to the heat transfer resistance of the outer walls, calculated according to winter heat transfer conditions. Claims of the invention A sun-protection device comprising a window box, on the outer side of which a rotatable screen is located, characterized in that, in order to increase the efficiency of the aperture sun shade and improve air flow circulation, the window box is made around the perimeter with a protrusion, and the rotary screen is made of translucent covered sunscreen film-ting, pivotally attached to the ledge, with the total area of the plates corresponds to the area of the window opening.
