Description

Technical Field

[0001] This utility model relates to a building lighting, heat insulation, and waterproof window well, belonging to the field of window well technology. Background Technology

[0002] Skylights are architectural features used in underground space engineering. Through the combination of overhead skylights and skylight structures, natural light is introduced into the underground space to improve lighting conditions. They also provide insulation and waterproofing, making them a key component of underground space building structures.

[0003] Currently, lighting in underground spaces mainly relies on traditional skylights, which typically consist of the skylight body and a roof lighting structure. While these systems provide basic lighting, they suffer from several significant drawbacks: Existing skylights often have flat or simple sloping windows, limiting their ability to refract and diffuse natural light. When light strikes at a small angle, localized areas of intense light or darkness can easily form inside the skylight, leading to uneven lighting in the underground space and even glare or shadows. This fails to meet the demands for high-quality lighting. Furthermore, the lack of reliable sealing between the skylight and the waterproof membrane layer allows hot and cold air to easily transfer through gaps, increasing energy consumption in the underground space. Utility Model Content

[0005] This utility model provides a building lighting, heat preservation and waterproof window well, which includes a basement wall and a lighting component. The basement wall is provided with a window well. The lighting component includes a lighting window and a suspended ceiling. The lighting window and the suspended ceiling are located at the top and bottom of the window well, respectively. The lighting window is pyramidal and fixedly connected to the basement wall. The window well includes an upper window well and a lower window well. The lower window well is trumpet-shaped.

[0006] A waterproof and thermal insulation component is installed between the window well and the basement wall. The waterproof and thermal insulation component extends along the outer surface of the window well to the bottom of the ceiling. A drainage pipe is installed inside the basement wall that penetrates the waterproof and thermal insulation component. The waterproof and thermal insulation component includes a waterproof membrane layer, a cement mortar plaster layer, and a graphite polystyrene board. The cement mortar plaster layer and the waterproof membrane layer are arranged sequentially from the outside to the inside on the waterproof and thermal insulation component. The graphite polystyrene board is located on the side of the waterproof and thermal insulation component closest to the window well and contacts the window well to insulate the window well.

[0007] Preferably, the window well is integrally formed, the upper window well is connected to the bottom of the skylight, and the upper window well and the lower window well are fixedly connected.

[0008] Preferably, the light-transmitting window is a convex pyramid shape, the lower window well expands linearly from top to bottom, and the lower window well is fixedly connected to the ceiling.

[0009] Preferably, the cement mortar plaster layer is located on the outside of the basement wall to enhance the flatness of the structural surface and provide a stable base layer for the waterproof membrane layer.

[0010] Preferably, a sealant is provided between the graphite polystyrene board and the waterproof membrane layer for sealing.

[0011] Preferably, the bottom of the skylight is provided with a support assembly, which includes a first support rod and a second support rod.

[0014] The beneficial effects of this utility model are:

[0015] This utility model provides a building lighting, heat insulation, and waterproof window well. The lighting window is convexly pyramidal, which refracts natural light with a small angle of incidence into the window well at a larger angle, effectively expanding the effective lighting time and range, allowing the basement to obtain more abundant and uniform natural light. The lower window well is funnel-shaped, expanding linearly from top to bottom. Combined with the suspended ceiling, direct light is refracted a second time, transforming into diffused light, further improving the uniformity of light in the basement and avoiding localized overly bright or dark areas. A waterproof and heat-insulating component is installed between the window well and the basement wall. A graphite polystyrene board is attached to the outside of the window well, effectively preventing the transfer of heat between the interior and exterior, providing good heat insulation. The graphite polystyrene board has excellent heat insulation performance and stability, maintaining its insulation effect for a long time, reducing basement energy consumption and improving indoor comfort. The waterproof and heat-insulating component includes a waterproof membrane layer and a cement mortar plaster layer. The cement mortar layer enhances the smoothness of the structural surface, providing a stable base layer for the waterproof membrane layer. This allows the waterproof membrane layer to better adhere to the structural surface, improving the integrity and sealing of the waterproof layer. A sealing block is installed at the top of the waterproof and thermal insulation component, providing a comprehensive seal and effectively preventing the intrusion of moisture, debris, and plant roots, thus protecting the integrity of the waterproof and thermal insulation component. A metal mesh is installed between the cement mortar layer and the waterproof membrane layer, covering the membrane layer. The flexible deformation of the metal mesh blocks the penetration of the main root while allowing fine roots to bypass it, forming a "soft and hard" barrier that effectively prevents damage to the waterproof membrane layer from plant roots. A support component is installed at the bottom of the skylight, including a first support rod and a second support rod. Through cross-setting and rigid connection, a spatial truss structure is formed, significantly enhancing the overall stability of the skylight and extending its service life.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1: This utility model provides a building lighting, heat insulation and waterproof window well, which includes a basement wall 1 and a lighting component 2. The basement wall 1 is provided with a window well 11, which is integrally formed. The lighting component 2 includes a lighting window 21 and a ceiling 22, wherein the lighting window 21 and the ceiling 22 are located at the top and bottom of the window well 11, respectively. The lighting window 21 is in the shape of an outwardly convex pyramid and is fixedly connected to the basement wall 1. The window well 11 includes an upper window well 111 and a lower window well 112. The upper window well 111 is connected to the bottom of the lighting window 21 and is rectangular. The lower window well 112 is located at the bottom of the upper window well 111 and is fixedly connected to the upper window well 111. The lower window well 112 is in the shape of a trumpet and expands linearly outward from top to bottom. The ceiling 22 is located at the bottom of the lower window well 112 and is fixedly connected to the lower window well 112.

[0023] A waterproof and thermal insulation component 3 is installed between the window well 11 and the basement wall 1. The waterproof and thermal insulation component 3 extends along the outer surface of the window well 11 to the bottom of the suspended ceiling 22. A drainage pipe 12 is installed inside the basement wall 1, and the drainage pipe 12 passes through the waterproof and thermal insulation component 3. The waterproof and thermal insulation component 3 includes a waterproof membrane layer 31, a cement mortar plaster layer 32, and a graphite polystyrene board 33. The cement mortar plaster layer 32 and the waterproof membrane layer 31 are arranged sequentially from the outside to the inside on the outside of the waterproof and thermal insulation component 3. The graphite polystyrene board 33 is located on the inside of the waterproof and thermal insulation component 3, close to the window well 11, to insulate the window well 11. A sealant 34 is provided between the graphite polystyrene board 33 and the waterproof membrane layer 31 for sealing.

[0024] In use, the skylight 21 is pyramidal in shape and works in conjunction with the upper window well 111 and lower window well 112 to prevent direct sunlight from creating localized strong light or dark areas, which can lead to poor lighting uniformity and potentially glare or shadows. The pyramidal structure refracts natural light with a small angle of incidence into the window well 11 at a larger angle, expanding the effective lighting time and range. The lower window well 112 expands linearly from top to bottom, and together with the suspended ceiling 22, it further refracts direct sunlight into diffused light, improving the uniformity of light in the basement and preventing localized overexposure. If the light is too bright or too dark, the gap between the basement wall 1 and the window well 11 is waterproofed and insulated by using a waterproof and thermal insulation component 3. The graphite polystyrene board 33 is attached to the outside of the window well 11 for thermal insulation, and the waterproof membrane layer 31 is waterproofed. A layer of cement mortar plaster 32 is built on the outside of the basement wall 1 to enhance the flatness of the structural surface and provide a stable base layer for the waterproof membrane layer 31. A drainage pipe 12 is installed inside the basement wall 1 to observe the waterproof and thermal insulation component 3, drain any water that may seep in, and prevent long-term erosion of the structure by water accumulation.

[0025] Compared with existing technologies, the skylight 21 is convex pyramidal in shape, which can refract natural light with a small angle of incidence into the window well (11) at a larger angle, effectively expanding the effective lighting time and range, so that the basement can obtain more sufficient and uniform natural light, reducing the dependence on artificial lighting and reducing energy consumption. The upper window well 111 is rectangular and connects to the bottom of the skylight 21, playing a role in initially guiding the light in. The lower window well 112 is located at the bottom of the upper window well 111 and is trumpet-shaped, expanding linearly outward from top to bottom. This combined structure, along with the skylight 21, further optimizes the light propagation path, allowing light to be distributed more evenly after entering the window well, avoiding areas that are too bright or too dark, and improving the overall uniformity of light in the basement. The suspended ceiling 22, located at the bottom of the lower window well 112, works in conjunction with the lower window well 112 to refract direct light a second time, converting it into diffused light, thus improving the lighting environment of the basement. A waterproof and thermal insulation component 3 is installed between the window well 11 and the basement wall 1, and this component extends along the outer surface of the window well 11 to the bottom of the suspended ceiling 22, achieving full coverage of the gap between the window well and the basement wall, effectively blocking light from entering the basement. The intrusion of external moisture and hot and cold air improves the overall waterproof and thermal insulation performance of the window well. The cement mortar plaster layer 32 is built on the outside of the basement wall 1, which enhances the flatness of the structural surface and provides a stable base layer for the waterproof membrane layer 31. This allows the waterproof membrane layer 31 to better adhere to the structural surface, improving the integrity and sealing of the waterproof layer. It effectively prevents moisture from seeping in from the gap between the basement wall 1 and the window well 11, extending the service life of the window well. The graphite polystyrene board 33 is located on the inside of the waterproof and thermal insulation component 3, close to the window well 11, and adheres to the outside of the window well 11. It can effectively prevent the transfer of heat between the inside and outside, and play a good thermal insulation role. The graphite polystyrene board 33 has excellent thermal insulation performance and stability, and can maintain its thermal insulation effect for a long time, reducing the energy consumption of the basement and improving the indoor comfort. A sealant 34 is applied between the graphite polystyrene board 33 and the waterproof membrane layer 31 for sealing, which further enhances the internal sealing of the waterproof insulation component 3, prevents the penetration of moisture and air between layers, and improves the reliability and durability of the entire waterproof insulation system. When moisture seeps in, the drain pipe 12 can drain the moisture in time, preventing water accumulation from damaging the window well structure and the basement environment, ensuring the normal use of the window well and the dryness and comfort of the basement.

[0026] Example 2: In the above example, the window well 11 is insulated and waterproofed by the waterproof and heat-insulating component 3. However, when using the traditional waterproof membrane layer 31, it relies on the material itself to resist the penetration of green plant roots. However, strong roots can still slowly penetrate, which cannot meet the needs of the entire life cycle of the building. Therefore, this application example is optimized based on the above example.

[0027] In this embodiment, a support component 23 is provided at the bottom of the light-transmitting window 21. The support component 23 is fixedly connected to the bottom of the light-transmitting window 21 and supports the top of the light-transmitting window 21. The support component 23 includes a first support rod 231 and a second support rod 232. The two first support rods 231 are arranged in a planar intersection. The two ends of the first support rod 231 are fixedly connected to the bottom of the light-transmitting window 21 respectively. The bottom of the second support rod 232 is fixedly connected to the intersection of the two first support rods 231, and its top is fixedly connected to the top of the light-transmitting window 21.

[0028] A sealing block 35 is provided on the top of the waterproof and thermal insulation component 3. The sealing block 35 is fixedly connected to the side wall of the window well 11 and the top of the basement wall 1 to seal the top of the waterproof and thermal insulation component 3, preventing water from entering and plant roots from entering the gap between the basement wall 1 and the window well 11 through the top of the waterproof and thermal insulation component 3 and causing damage to the waterproof and thermal insulation component 3. A metal mesh 36 is provided between the cement mortar plaster layer 32 and the waterproof membrane layer 31. The metal mesh 36 covers the waterproof membrane layer 31. The flexible deformation of the metal mesh 36 blocks the penetration of the main root of the root system, while allowing the fine roots to bypass it. The physical barrier forces the roots to change their growth direction and avoid directly penetrating the waterproof membrane layer 31.

[0029] In use, the first support rod 231 is fixedly connected to the bottom of the skylight 21, and the second support rod 232 supports the skylight 21. The rigid connection with the intersection point forms a spatial truss to further increase the stability of the skylight 21. The sealing block 35 is located above the basement wall 1 and is fixedly connected to the basement wall 1 and the window well 11. The sealing block 35 covers the top of the waterproof and thermal insulation component 3 to prevent plant roots or other debris from entering the gap between the basement wall 1 and the window well 11 and damaging the waterproof and thermal insulation component 3. A metal mesh 36 is provided between the cement mortar plaster layer 32 and the waterproof membrane layer 31, which can effectively intercept the roots of plants planted around the basement wall 1, forming a "soft and hard combination" barrier. This not only avoids hard collisions that could damage the waterproof membrane layer 31, but also utilizes the ductility of metal to adapt to the micro-deformation of the foundation, preventing plant roots from directly piercing the waterproof membrane layer 31.

[0030] Compared with existing designs, by setting a support component 23 at the bottom of the skylight 21, and through the combination of the first support rod 231 and the second support rod 232, an effective support system is formed for the skylight 21, significantly enhancing the overall stability of the skylight 21, extending its service life, and reducing the repair and replacement costs caused by damage to the skylight 21. The two first support rods 231 are arranged in a planar cross configuration, with both ends fixedly connected to the bottom of the skylight 21. This cross configuration can evenly distribute the external force on the skylight 21 to each support point, optimizing the force transmission path, improving the stability and reliability of the support, and reducing the risk of deformation of the skylight 21 due to excessive local stress. The bottom of the second support rod 232 is fixedly connected to the intersection of the two first support rods 231, and the top is fixedly connected to the top of the skylight 21, and to the first support rod 232. The rod 231 forms a spatial truss structure, further enhancing the vertical stability of the skylight 21. It effectively resists the weight of the skylight 21 itself and external vertical pressure, ensuring the skylight 21 remains flat and stable during long-term use, guaranteeing both lighting performance and the overall safety of the building. A sealing block 35 is installed on the top of the waterproof and thermal insulation component 3, fixedly connected to the side wall of the window well 11 and the top of the basement wall 1, providing a comprehensive seal to the top of the waterproof and thermal insulation component 3. This effectively prevents the intrusion of moisture, debris, and plant roots, protecting the integrity of the waterproof and thermal insulation component 3, extending its service life, ensuring the dryness and insulation effect of the basement, and reducing maintenance and energy consumption costs caused by damage to the waterproof and thermal insulation component. A metal mesh 36 is installed between the cement mortar plaster layer 32 and the waterproof membrane layer 31, covering the waterproof membrane layer 31. The metal mesh 36 utilizes its flexible deformation to prevent the main root from penetrating while allowing fine roots to bypass it, forcing the roots to change their growth direction through a physical barrier, preventing direct penetration of the waterproof membrane layer 31. This "soft and hard" barrier design effectively prevents plant roots from damaging the waterproof membrane layer 31, ensuring the waterproof performance of the waterproof insulation component 3. It also utilizes the ductility of metal to adapt to slight foundation deformation, avoiding cracks between the waterproof membrane layer 31 and the metal mesh 36 caused by foundation deformation. This further improves the reliability and durability of the waterproof insulation component 3, extends the service life of the building, and reduces maintenance costs and risks caused by plant roots damaging the waterproof layer.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
