Description

Technical Field

[0001] The present invention is a divisional application of 2023110900138, and belongs to the technical field of energy-saving doors and windows, and specifically relates to an integrated external sunshade device that integrates heat-insulating doors and windows with external sunshade roller blinds. Background Art

[0002] External shading has a very significant energy-saving effect and is considered to be the most ideal passive energy-saving measure for window openings. For example, in a building with a 10% window-to-wall ratio, the window opening is the weakest link in the building envelope, and 44.4% of energy consumption is usually lost at the window opening. In the environment of vigorously promoting and implementing building energy conservation, various forms of external shading facilities have been widely used on the external windows of residential buildings in the hot summer and cold winter areas in the south and the Yangtze River Basin, among which external shading roller blinds are the most widely used.

[0003] However, most of the current external sunshade roller blinds are installed on the outer window openings of the building's exterior windows or on the exterior walls. This installation method brings the following problems: (1) The shape and color of the external sunshade device affect the overall visual effect of the building's exterior; (2) The retractable and extended space of the external sunshade device interferes with the opening and closing space of the exterior window. Once a failure occurs during use, it is easy to be blocked by the door and window, making it difficult to repair; (3) When the roller blind box and the building's exterior window are installed side by side in the building's window opening, because the sum of the depths of the two is greater than the wall thickness, the roller blind box is often forced to extend out of the exterior wall, affecting the visual effect of the building's exterior wall; (4) When using rear anchors for installation, the exterior wall insulation layer is damaged, which will reduce the insulation effect of the building's exterior wall, or damage the exterior wall waterproof layer. This will lead to water leakage and seepage on the exterior walls of buildings in the future; (5) The roller shutter boxes and guide rails are not firmly anchored, which can easily cause the roller shutter parts, components and even products to loosen and fall off; (6) When installed in the window opening, it blocks part of the lighting area of ​​the exterior window; (7) When installed on the exterior wall, it increases the windward area of ​​the exterior shading device; (8) When the roller shutter fails, personnel must climb outside the building window to repair or remove it, which is very dangerous when used for repairs on high-rise buildings; (9) When installed in the window opening, the width and height of the exterior shading roller shutter are often determined by measuring the actual size of the hand-painted window opening rough surface. It is impossible to unify the size, which makes it difficult to use standardized and mass production and processing methods, which is inconvenient for production management and cost control.

[0004] To this end, the applicant has integrated the design, manufacture and installation of external sunshade products with the building's external windows, and installed the external sunshade products on the external windows in the factory, which not only solves the above-mentioned problems, but also facilitates manufacturing, transportation and installation. After installation, the entire building facade has a beautiful and uniform appearance, and the external sunshade roller blinds are integrated with the building's external windows, forming an integrated structure on the building's facade, which makes it easier to reflect the overall design and quality of the building. In addition, in the architectural design stage, it is designed as a whole with the building's thermal insulation and waterproofing structures, and installed in place at one time in the construction stage, saving installation time. For example, the Chinese patent document CN107044251A provides an external sunshade roller blind system that can be installed as a whole with doors and windows and is easy to maintain, which has been actually applied in many projects and has been widely praised by the owners.

[0005] The applicant pays attention to user feedback and data accumulation during the product promotion process, continuously invests in research and development to optimize and improve the product in order to obtain a better user experience, and injects innovative technology to continuously enhance the competitiveness and added value of the product.

DETAILED DESCRIPTION

[0035] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] like Figure 1-6 As shown, an integrated external shading device is proposed in an embodiment of the present invention, which aims to realize the assembly of the external shading device in the window opening of a building, enhance the visual integration effect between the device and the building wall, improve the thermal insulation performance at the window opening, and reduce the energy consumption of the building.

[0037] An integrated external sunshade device proposed in the embodiment of the present invention abandons the split design and installation method of traditional external sunshade products, combines the window machine into one, simplifies the engineering design and construction process, avoids damage to the external wall due to secondary construction, and improves construction efficiency. The integrated sunshade device uses a closed box body with an inner circle and an outer square formed by splicing a top plate, an outer plate, a bottom plate, an inspection plate and two end seats as a rolling shutter box, connects the top plate to the building wall structure, connects the top of the door and window to the bottom plate, and fits the outer plate to the external wall insulation layer, so that the outdoor side of the rolling shutter box is directly covered by the overall external wall insulation layer, which improves the visual integration effect between the device and the building wall, improves the thermal insulation performance at the window opening, and reduces the building energy consumption.

[0038] like Figure 1 As shown, the integrated external sunshade device is fixedly connected into one by a system window and an external sunshade roller blind. The roller blind box 1 of the external sunshade roller blind is fixedly installed on the top of the inward opening window 8, and the guide rail 4 is fixedly installed on both sides of the window frame. The cross-section of the guide rail 4 is L-shaped, and has a mounting section and a guide section that are perpendicular to each other. The top of the mounting section is fixedly connected to the end seat 2, and one side wall of the mounting section is fixedly connected to the window frame. The guide section has grooves for accommodating the two side edges of the foam curtain sheet 10.

[0039] like Figure 2 As shown, the shutter box body 1 is designed to be a structure assembled of four pieces of wood-plastic profiles, namely, a top plate 11, an outer plate 12, a bottom plate 13 and an inspection plate 6, wherein the outer contour of the top plate 11 is L-shaped, the outdoor side is directly connected to the vertical outer plate 12, and the indoor side extends downward by about 1 / 4 of the entire box height, and is designed with a sealing groove and a connecting groove, and the connecting groove and the protrusion on the inspection plate 6 form a detachable hinge structure, a plurality of cavities are arranged inside the inspection plate 6, the whole is thickened, and the bottom extends to be flush with the shutter box body 1, and the two ends of the shutter box body 1 are fixed with an end seat 2 and an end seat 2 connecting plate 3. The inner surfaces of the top plate 11, outer plate 12, bottom plate 13 and inspection plate 6 of the rolling shutter box 1 are all arc surfaces. Starting from the inner surface of the bottom plate 13, the curvature of the cylindrical surface of each plate increases in equal sections, and the adjacent cylindrical surfaces are smoothly connected, so that the gap between the inner cavity surface of the curtain box and the cylindrical surface formed by the winding of the rolling shutter, whose generatrix is ​​similar to the Archimedean spiral, is close to uniform, and the capacity of the curtain box for the rolling shutter is maximized.

[0040] like Figure 2As shown, the interior of the sealed box body has a rolling curtain cavity for accommodating the foam curtain sheet 10 and the roller 7, and the bottom of the rolling curtain cavity is provided with a slot for the foam curtain sheet 10 to enter and exit. The head end of the rolling curtain structure formed by sequentially connecting the foam curtain sheets 10 is connected to the side wall of the roller 7, and the tail end of the rolling curtain structure is provided with a bottom beam 21. On the one hand, the bottom beam 21 is conducive to improving the tension of the foam curtain sheet 10 in the vertical direction, so that each foam rolling curtain 10 is fully unfolded during the rolling process; on the other hand, the bottom beam 21 is convenient for the rolling curtain structure to contact with the frame of the door and window, which is conducive to further improving the sealing of the tail end of the rolling curtain structure.

[0041] like Figure 3 As shown, screws are arranged in a triangle on the end seat 2 connecting plate 3, and the screws are respectively connected to the two reinforcing steels lined in the top plate 11 and the two ends of a reinforcing steel lined in the bottom plate 13 to form a reinforced frame. The two reinforcing steels lined in the top plate 11 are used to receive the fixing screws of the installation angle code 14, and the reinforced steel lined in the bottom plate 13 is used to receive the installation screws of the window frame. In this way, the entire rolling shutter box 1 is used as a structural component installed between the top of the building window opening and the top frame of the door and window to receive the installation of the door and window. The lining steel frame and the end seat 2 connecting plate 3 form an lining reinforcement frame to strengthen the structural strength of the rolling shutter box 1, and the lining steel frame is used to bear the force to ensure that it is used as a connection and force-bearing component for fixing the door and window to the building.

[0042] like Figure 4 As shown, the top of the inspection panel 6 has a hook-shaped structure that forms a detachable hinge with the top plate 11, and the outside of the inspection panel 6 is installed with an inspection decorative cover 5. The inspection decorative cover 5 is made of aluminum profiles with the same material and surface treatment as the door and window profiles, and the inspection panel 6 is completely surrounded by the inspection decorative cover 5 on the indoor side, so that a visually integrated and easy-to-maintain structure is formed on the indoor side. An aluminum alloy trim strip 19 is installed on the indoor side of the top plate 11, and its bottom edge is raised, close to the top of the inspection cover, and the raised reinforcement ribs on one side are embedded in the leveling layer and the paint layer of the indoor wall, and the bottom has a structure that forms a hinge with the inspection decorative cover 5.

[0043] The ratio of the height of the indoor side of the shutter box 1 covered by the inner wall paint layer 16 to the total height of the shutter box 1 is greater than 0.5 and less than 0.8. In this way, the indoor side of the shutter box 1 is composed of the inspection plate 6 and the lower hanging section of the L-shaped top plate 11, which is conducive to coating the outer side of the lower hanging section with an inner wall insulation layer, thereby reducing the exposed area of ​​the shutter box 1 on the indoor side and improving the visual style integration effect.

[0044] like Figure 5 and Figure 6As shown, the integrated sunshade door and window rolling system of the present invention can integrate the external sunshade roller blinds and doors and windows during factory manufacturing, that is, the roller blinds are fixedly connected to the inner lining steel of the bottom plate 13 of the roller blind box 1 from the top of the window frame with screws, and the guide rails 4 are fixed on both sides of the window frame. The overall thickness of the roller blind box 1 is about 200mm, which is the same thickness as the most commonly used wall in buildings, ensuring that the inside and outside of the wall are flush after installation. After the outdoor insulation layer and the indoor paint layer are constructed, the roller blind box can be integrated with the wall.

[0045] During installation, firstly, the angle bracket 14 is fixed to the inner lining steel of the top plate 11 with screws at the top of the rolling shutter box 1, and then the angle bracket 14 is inserted into the two sides of the wall at the top of the window hole, and the angle bracket 14 is fixed to the wall with expansion bolts. Then, the two sides of the window frame, the guide rail 4, and the bottom of the window frame are installed on the energy-saving auxiliary frame 20 in the window hole / door hole.

[0046] When installed in this way, the roller shutter box 1 is flush with the inside and outside of the building wall. After the external sunshade and system window are installed as one, the external wall insulation layer 15 and the internal wall paint layer 16 are constructed, and the internal wall leveling and paint layer are formed with the edge of the inspection cover using the edge strip 19. The external wall insulation layer 15 is constructed at the bottom end of the front plate (at the curtain plate exit) and the enclosure 17 is used to form a closing edge. A T-shaped decorative strip of the same material as the window frame can also be installed between the outdoor side of the bottom plate 13 and the window frame, and a water stop is provided at the bottom of the decorative strip, so that all exposed parts of the roller shutter box 1 are integrated with the visual style of the window frame.

[0047] A trim strip 19 is installed on the indoor side of the top plate 11, and its bottom has a raised edge as a stop for the inner wall leveling layer and the plaster layer, and its side wall has a protrusion for embedding the inner wall leveling layer; the inspection decorative cover 5 and the trim strip 19 are made of aluminum profiles with the same material and surface as the door and window profiles, and the inspection plate 6 is completely surrounded by the inspection decorative cover 5 on the indoor side. The trim strip 19 and the inspection decorative cover 5 allow the roller shutter box 1 to be partially buried in the inner wall on the indoor side, and the exposed part forms a first step transition with the inner wall and a second step transition with the doors and windows. The inner wall-inspection decorative cover 5-doors and windows form an indoor structure that is visually integrated and easy to inspect; the bottom plate 13 of the outer panel 12 is installed with a panel 17, and the panel 17 has a drip groove and is connected to the outer wall insulation layer 15, and the roller shutter box 1 on the outdoor side is completely hidden in the outer wall insulation layer 15.

[0048] The top plate 11, bottom plate 13, outer plate 12, and inner inspection plate 6 of the rolling shutter box 1 are all made of high thermal resistance materials, and multiple cavities that can increase thermal resistance are set on the profile section. The outdoor side of the rolling shutter box 1 is directly covered by the overall exterior wall insulation layer 15, and the inner inspection plate 6 on the indoor side is designed with a sealing structure and a thickened and enlarged cavity, which eliminates the thermal bridge between the rolling shutter window and the indoor room, has excellent air tightness and thermal insulation, and has a very good effect on energy saving. In addition, a strong air insulation layer is formed between the glass window and the rolling shutter window, which can effectively block the exchange of cold and hot air flows between indoor and outdoor, and realize thermal insulation functions. Further improve the overall performance of ultra-low energy consumption buildings.

[0050] When an integrated external sunshade device proposed in the embodiment of the present invention is used, the split design and installation method of traditional external sunshade products is abandoned, and the window machine is integrated into one, which simplifies the engineering design and construction process, avoids damage to the external wall due to secondary construction, and improves construction efficiency. The traditional external installation method is changed to an embedded wall installation method to avoid the safety hazard of falling of later products and improve product safety. The complex structure of the facade is simplified to enhance the integration effect.

[0051] The rolling shutter box adopts hollow plastic wood profiles with good thermal resistance as the main structure, which ensures the strength of the box and the thermal insulation performance of the box. The product is designed with an indoor maintenance window that is easy to open, which is conducive to the later wiring construction and maintenance. The rolling shutter box is embedded with a steel frame, which can not only strengthen its own strength, but also ensure the strength of the connection with the window frame. At the same time, the wire pressing openings at the joints of the profiles of the rolling shutter box are sealed with rubber sealing strips and dripping mouths.
