Description

Technical Field

This invention is related to a polycarbonate plate with a pendentive form which may be used as roof skylight in all types of roofs and between the roofing panels.
The invention is especially related to a polycarbonate pendentive roof skylight which is used as a ceiling cover in the roofs and enables householders to make use of sunlight thanks to its transparent structure, can be mounted easily without any steel skeleton or any additional structuring and have a high load bearing feature and endurance.

Prior Art

In prior art, there are various lighting systems used to take advantage of sunlight from the roof of buildings. Among these systems, polycarbonate roof skylights with a pendentive form are frequently preferred. Pendentive is the structure which is formed by clustered arcs in architecture and which generally functions as roof cover. Polycarbonate skylights with this form are applied to the highest level of roofs, namely the ridge point.
There are various deficiencies of prior art applications of roof skylights. One of these deficiencies is that, the load bearing feature of the prior art systems is not sufficient. Therefore, these systems are reinforced by applying aluminum or steel skeleton under the panel. However, such an application complicates the installation process, increases the installation time and labour. Therefore, the current systems are not economic. Besides that, the present systems can not be mounted onto every sort of panel roof.
Because of their flat structure, currently used inter panel polycarbonate plates can not be used in flat or low sloped roofs due to precipitation. The difficulty of differentiation from the dirty panels due to environmental factors during a walk for checking and the risks they pose in terms of job security and the low light they receive are among the other disadvantages of the current systems.
Consequently, as a result of the need for new structures which would eliminate the aforementioned drawbacks and offer solutions to the existing systems in the roof skylight structures installed onto the roofs to make use of sunlight, new systems have been developed.

Object Of The Invention

The present invention relates to the polycarbonate roof light with pendentive form meeting the said needs, eliminating all disadvantages and providing some extra advantages.
An object of the invention is to provide more light to the interior spaces thanks to the pendentive form structuring of the roof light which includes a convex surface.
The purpose of the invention is to increase the bearing characteristic and strength of the roof skylight which is designed in pendentive form with thick walls.
Another object of the invention is to obtain flexibility in manufacturing process by producing the roof skylight according to the requested dimensions and thus, to make it complying with all sorts of panels.
Another object of the invention is to save labour and time by the ability to mount the roof skylight with pendentive form especially into the narrow and small areas easier and cheaper.
Another object of the invention is to provide more heat and sound insulation in the application field of the roof light.
Thanks to the connecting lugs which provide water isolation naturally owing to their special form, a more economic roof skylight is intended in terms of water sealing.
By the virtue of the invention, the roof skylight is mounted easier and cheaper without any aluminum or steel skeleton under the panel during the mounting.
An object of the invention is to reduce the possible job safety risks while walking on the roof, since it can be distinguished from the other dirty panels easily.
With the present invention, a pendentive roof skylight is obtained onto which a ventilation hatch can be mounted easily and which can be mounted onto all sorts of panels easily.
In the current pendentive skylight applications, the maximum plate thickness is 6mm while in the present invention, a structuring with high insulation whose thickness may be up to 20 mm is targeted.
Another object of the invention is to easily apply the pendentive skylight as a light band in the bowless roofs and membrane roofs.
The present invention is a pendentive shaped roof skylight which may be used as a skylight in all sorts of roof types and between the roofing panels and made of polycarbonate etc. transparent material in order to realize all the advantages which are explained above and will be understood from the detailed description given below, wherein said invention comprises the following:

hollow chambers between a concave and a convex surface, stacked one on another and side by side forming an arc shape,
at least one connection region which is located on both ends of the curved shape formed by the said chambers and which provides the mounting of the skylight to the floor.

In the preferred embodiments of the invention, there are isolation lugs which are integral (one piece) with the ends of the connection regions and form an eave structure for water sealing by sloping downwards.
The structural and the characteristic features and all advantages of the invention will be understood more clearly with the detailed description written by referring to the following figures and therefore, the evaluation needs to be done by taking these figures and the detailed description into consideration.

Detailed Description Of The Invention

In this detailed description, preferred embodiments of the roof light with pendentive form according to the invention are described only for a better understanding of the subject without constituting any restrictive effect.
This invention is a polycarbonate panel (1) with a pendentive form which may be used as roof light in all types of roofs and between the roofing panels. In Figure 1, side profile view of a preferred embodiment of the roof skylight (1) with pendentive shape subject to the invention is given. Roof skylight (1) is made of polycarbonate material. Since it is a transparent material, it transmits light.
As it may be seen from Figure 1, the main body of the roof skylight (1) subject to the invention consists of small chambers (6) between a concave surface (2) and a convex surface (3). This structure forms an arc as a whole. The small chambers (6) arranged side by side within this form resembles the arc shape called pendentive in architecture. Pendentive form is used in architecture since ancient times and it is used for transferring the weight and the loads to the floor.
Connection regions (4), which mount the skylight (1) to the roof or to the floor of the panel, are located on both sides of the curved body in pendentive form. The said connection region (4) is insulated and have thick walls. Isolation lugs (5) are located in both ends of the roof skylight (1). Said isolation lugs (5) are designed for water sealing. Isolation lugs (5) are one piece with the curved panel body of the skylight (1) and they are adjacent to the connection region (4). Isolation lugs extend from the connection region (4) -designed parallel to the floor- with a predetermined slope and thus form an eave structure.
In Figure 2, side profile view of a cross section of the polycarbonate roof skylight (1) with pendentive shape subject to the invention is given. In said cross section the horizontal and vertical partition walls (7, 8) forming the chambers (6) are seen. The horizontal and vertical partition walls (7,8) intersect each other vertically and thus, they form the rectangular shaped (from the side profile) chambers (6). The said chambers (6) form the curved pendentive form by being aligned side by side beginning from one connection region (5) of the roof sky light (6) to the other and this form may be as thick as 20 mm. This structuring gives extra strength to the skylight (1) and it also reduces the weight and enhances the heat insulation of the skylight (1). Additionally, by the virtue of created arc structure, there will not be any precipitation accumulation on the roof skylight (1) and thus, it will be possible to use it even on the roofs with little or no slope.
The highly durable structure obtained by the arc structure provides an easy mounting of the roof skylight (1) without using any steel skeleton or any additional structure. This new structuring which may be constructed even in narrow and small areas provides a decrease in the labor costs and shortens the mounting time. The arched structure, which is formed by hollow chambers (6) and has a thickness up to 20 mm, enhances both the heat insulation and the sound insulation and it also allows the indoor environments to benefit more from the sunlight by letting more sunlight enter into the indoor environment from the roof.
The polycarbonate roof skylight (1) with pendentive form subject to the invention easily complies with all sorts of panels since it may be manufactured in the desired dimensions. Being one piece and having connection lugs at the side parts, the roof skylight (1) makes the water sealing easier and more economic. The pendentive skylight (1) may be easily used as a light band on the roofs with no slope or on the membrane roofs.
