Description

Technical Field

[0001] This invention belongs to the field of skylight construction technology, and in particular relates to a large-angle, ultra-large area openable roof skylight system. Background Technology

[0002] Openable skylights are movable units that can be manually or electrically controlled to improve indoor temperature, humidity, and environment under different weather conditions. Openable roofs are increasingly used in public buildings such as airports, conference and exhibition centers, and stadiums. With the development of architecture, the application of irregularly shaped and sloping roofs is becoming more widespread. Modern architecture emphasizes a simple and grand style, and the number of skylight compartments and their application areas are getting larger. This poses a significant challenge to the overall structural rationality of the skylight system and places increasingly higher demands on long-term smoke control and exhaust. While openable skylights achieve ventilation, lighting, and smoke control, leakage is a critical and difficult problem that urgently needs to be solved. Existing skylight systems rely solely on their own waterproofing, without considering how rainwater can drain after seepage. Long-term accumulation of rainwater can easily lead to leakage hazards. Moreover, existing skylight systems designed for steeply sloping roofs cannot complete the opening of the smoke storage compartment within the time limits allowed by fire safety regulations, failing to achieve the required smoke exhaust effect and posing safety hazards. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a large-area, tilt-angle, openable roof skylight system that, while achieving ventilation and lighting functions, solves the problems of smoke prevention and exhaust during the long opening time of large-area, tilt-angle skylights and the tendency for leakage.

[0004] The present invention achieves the above-mentioned technical objectives through the following technical means.

[0005] A large-area, tilt-angle, operable roof skylight system includes fluorocarbon-coated welded steel pipes. Multiple fluorocarbon-coated welded steel pipes are welded and fixed at both ends to the main steel structure of the roof. Near the upper end of each fluorocarbon-coated welded steel pipe, multiple sets of fluorocarbon-coated square steel are symmetrically welded to both sides, forming the main and secondary keel structure of the roof skylight system. A continuous transition channel steel is welded and fixed to the upper end of each fluorocarbon-coated welded steel pipe. A custom-made waterproof aluminum alloy support frame is installed along the entire length of the transition channel steel. Aluminum alloy fixing frames are embedded on both sides of the custom-made waterproof aluminum alloy support frame, and aluminum alloy opening sashes are installed on the aluminum alloy fixing frames, forming the skylight frame. Insulating tempered laminated glass is embedded between adjacent aluminum alloy opening sashes. An electric window opener is installed between the fluorocarbon-coated welded steel pipe and the skylight frame.

[0006] Furthermore, the customized waterproof aluminum alloy support frame includes a heat insulation pad, an aluminum alloy pad, a customized EPDM rubber strip, and a base A. The heat insulation pad is located in the middle and is arranged along the entire length. The aluminum alloy pad is arranged along the upper end of the fluorocarbon-coated welded steel pipe. The aluminum alloy pad is fixed to the base A by machine screws. A customized EPDM rubber strip is also embedded between the heat insulation pad and the base A.

[0007] Furthermore, the main frame of both the aluminum alloy fixing frame and the aluminum alloy opening sash is provided with multiple drainage holes that are interconnected. A secondary water guide groove is formed between the aluminum alloy fixing frame and the aluminum alloy opening sash, and the secondary water guide groove is connected to the drainage holes for the discharge of condensate inside the window frame. A water collection groove is reserved on the main frame of the aluminum alloy fixing frame, and the water collection groove is connected to the drainage holes for the discharge of condensate.

[0008] Furthermore, the main frame of the aluminum alloy fixing frame is also provided with four thermal insulation strips for achieving thermal break insulation.

[0009] Furthermore, three EPDM rubber strips are provided at the contact position between the aluminum alloy opening fan and the aluminum alloy fixing frame for waterproofing; the aluminum alloy opening fan is also provided with a condensate collection tank for collecting condensate.

[0010] Furthermore, the lower end of the electric window opener is hinged to the fluorocarbon-coated welded steel pipe via a connecting steel component and screws, and the upper end of the electric window opener is fixed to the skylight frame via a base B. The base B is connected to the electric window opener via bolts and to the skylight frame via small custom-made steel components.

[0011] Furthermore, a 2mm thick insulating pad is provided between the customized waterproof aluminum alloy support frame and the conversion channel steel.

[0012] Furthermore, the customized waterproof aluminum alloy support frame is fixed to the conversion channel steel by multiple self-tapping screws, with the spacing between the self-tapping screws not exceeding 30cm.

[0013] The present invention has the following beneficial effects:

[0014] This invention employs a combined waterproofing and drainage design for its skylight system, enhancing its leak-proof capabilities. Thermal insulation is achieved through the use of insulating pads and strips, while a high-power electric window opener with a controlled opening stroke and thrust enables time-limited opening of large-area skylights with steep inclines. The aluminum alloy frame incorporates secondary water channels and drainage holes. Rainwater flows through these holes to a collection trough and is then guided through an organized drainage system to the gutter, achieving a superior combination of waterproofing and drainage. This system provides ventilation and lighting while addressing the requirements for smoke extraction during extended opening times and the potential for leakage in large-area skylights with steep inclines.

[0015] The electric window opener of this invention has a linkage function with the fire alarm system. During fire smoke exhaust, the electric window opener can centrally open the skylights of the corresponding areas according to the smoke control zone through linkage with the fire control center or manual alarm button. The electric window opener adopts both manual and linkage control modes, and is equipped with wind and rain sensors and temperature sensors to ensure that indoor temperature and humidity can be controlled and indoor lighting and ventilation requirements can be met.

A conversion channel steel 3 is welded and fixed to the upper end of each fluorocarbon-coated welded steel pipe 1. The conversion channel steel 3 is arranged along the entire length of the fluorocarbon-coated welded steel pipe 1 and is used to connect the upper and lower structures, transmit force, and adjust the finished surface elevation.

[0024] like Figure 1 , 2 As shown, a custom-made waterproof aluminum alloy support frame 4 is installed along the entire length of the surface of the conversion channel steel 3 using self-tapping screws. The custom-made waterproof aluminum alloy support frame 4 includes a heat insulation pad 41, an aluminum alloy pad 42, a machine screw 43, a custom EPDM rubber strip 44, and a base A45. The heat insulation pad 41 is located in the middle of the custom-made waterproof aluminum alloy support frame 4 and is arranged along the entire length to achieve the thermal break effect. The aluminum alloy pad 42 is arranged along the upper end of the fluorocarbon sprayed welded steel pipe 1. The aluminum alloy pad 42 is fixed to the heat insulation pad 41 on the base A45 by the machine screw 43. A custom EPDM rubber strip 44 is also embedded between the heat insulation pad 41 and the base A45.

[0025] like Figure 1 , 3 As shown, aluminum alloy fixing frames 5 are embedded on both sides of the customized waterproof aluminum alloy support frame 4 and fixed by machine screws 43. An aluminum alloy opening sash 6 is installed on the aluminum alloy fixing frame 5. The aluminum alloy fixing frame 5 and the aluminum alloy opening sash 6 together form the skylight window frame. The aluminum alloy fixing frame 5 serves as the fixed window frame of the hollow tempered laminated glass 7, and the aluminum alloy opening sash 6 serves as the operable window sash of the hollow tempered laminated glass 7. The aluminum alloy fixing frame 5 and the aluminum alloy opening sash 6 are fixed by hinges.

[0026] like Figure 1 , 3 As shown, the main frame of both the aluminum alloy fixed frame 5 and the aluminum alloy operable sash 6 is provided with multiple interconnected drainage holes 52. A secondary water guide groove 51 is formed between the aluminum alloy fixed frame 5 and the aluminum alloy operable sash 6. The secondary water guide groove 51 is connected to the drainage holes 52 for the drainage of condensate inside the window frame. The customized window frame profile of the aluminum alloy fixed frame 5 has a reserved water collection groove 53. The water collection groove 53 is connected to the drainage holes 52 for the drainage of condensate. The main frame of the aluminum alloy fixed frame 5 is also provided with four thermal insulation strips 54 for thermal break insulation of the window system.

[0027] like Figure 1 , 3As shown, the aluminum alloy openable fan 6 includes three EPDM rubber strips 61 disposed at the contact position with the aluminum alloy fixed frame 5 for waterproofing; it also includes a condensate collection tank 62 for collecting condensate.

[0028] like Figure 1 As shown, the hollow tempered laminated glass 7 is embedded between adjacent aluminum alloy operable windows 6 to form a complete unit for windproofing, rainproofing and light transmission; the traditional warm method of installation is adopted, and the fixing is achieved by connecting the sub-frame and the pressure plate. The pressure plate is used to position the glass panel to achieve the purpose of positioning and installation. This part is the conventional installation structure and installation method.

[0029] like Figure 1 As shown, the lower end of the electric window opener 8 is hinged to the fluorocarbon-coated welded steel pipe 1 via a connecting steel part 81 and screws. The upper end of the electric window opener 8 is fixed to the skylight frame via a base B82. The base B82 is bolted to the electric window opener 8 and welded to the skylight frame via small custom-made steel parts. The electric window opener 8 is a conventional and general-purpose device, and its structure will not be described in detail. The electric window opener 8 is the power unit of the entire roof skylight system. It is connected to the intelligent control system such as the fire control module and, combined with the detection data from the wind and rain sensors and temperature sensors installed outdoors, controls the opening of the skylight system to adjust the indoor temperature, humidity, and lighting conditions, realizing the joint control opening and closing of the skylight and the fire-fighting opening and closing function. This part is not within the scope of protection of this invention and will not be described in detail.

[0030] Before installing the custom waterproof aluminum alloy support bracket 4, a 2mm thick isolation pad is placed on the surface of the conversion channel steel 3. Then, the base A45 of the custom waterproof aluminum alloy support bracket 4 is fixed on the conversion channel steel 3 with self-tapping screws, with the interval between the self-tapping screws not exceeding 30cm.

[0031] After the aluminum alloy internal drainage profile is installed and its dimensions are verified to be within acceptable limits, the custom EPDM rubber strips 44 are installed. Installation proceeds from low to high, with the vertical strips following the slope, followed by the horizontal strips. The vertical and horizontal strips overlap, ensuring the drainage channel is unobstructed and allowing condensate from the window system to drain through controlled channels from the lower side. The custom waterproof aluminum alloy support frame 4 has drainage channels on both sides to collect seepage rainwater and ultimately direct it into the gutter. Rainwater flows through the drain holes 52 to the collection trough 53 and is then guided to the gutter through organized drainage.

[0032] The embodiments described above are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Any obvious improvements, substitutions or modifications that can be made by those skilled in the art without departing from the essence of the present invention shall fall within the protection scope of the present invention.
