Abstract
Description
Technical Field
[0001] This utility model relates to the field of building materials and building energy conservation technology, and in particular to a thermal insulation type building exterior wall. Background Technology
[0002] Building exterior walls are the external envelope of a building. With the increasing requirements for building energy conservation, the thermal insulation performance of building exterior walls, as an important component of the building envelope, has a significant impact on building energy consumption. Currently, the main thermal insulation methods for building exterior walls on the market are internal insulation and external insulation.
[0003] A search revealed Chinese Patent Publication No. CN204826394U, which discloses an exterior wall for buildings, comprising a keel frame, an insulation layer inside the keel frame, an outer concrete layer on the outer wall of the insulation layer, an I-beam frame at the top of the keel frame, wire mesh layers on the open sides of the I-beam frame, a fireproof layer on the outer side of the wire mesh layer, a fireproof layer on the top of the keel frame on the same side as the outer concrete layer, and camphor wood block layers on the middle and bottom of the keel frame on the same side as the outer concrete layer. This utility model employs a fireproof layer on the outside of the keel frame and the wire mesh. The wire mesh layer facilitates the adhesion of the fireproof layer, preventing material from entering the inner cavity of the frame and reducing the load-bearing capacity of the keel frame, resulting in a lighter wall. A camphor wood block layer on the same side as the outer concrete layer prevents insect infestation of the decorative layer, ensuring its integrity and thus increasing the wall's lifespan. However, in practical use, while the camphor wood block layer improves the wall's lifespan, it suffers from poor heat insulation in high summer temperatures and insufficient thermal insulation in cold winters, leading to increased building energy consumption.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a thermally insulated building exterior wall, comprising a wall 1. A thermal insulation mechanism 2 is provided at the bottom of the inner wall of the wall 1 to improve the thermal insulation performance of the wall 1. A weathering mechanism 3 is provided on the front side of the wall 1 to improve the weather resistance of the front side of the wall 1. The thermal insulation mechanism 2 includes a gel board 201, the top of which is fixedly connected to the front side of the inner top wall of the wall 1. The gel board 201 enhances thermal insulation. A rock wool board 202 is fixedly connected to the rear side of the gel board 201. Multiple fireproof strips 203 are fixedly connected to both the front and rear sides of the rock wool board 202. The connection between the rock wool board 202 and the multiple fireproof strips 203... The following measures can effectively improve the fire resistance of the interior wall 1. A fixing plate 204 is fixedly connected to the rear side of the rock wool board 202, and multiple polyurethane foam boards 205 are fixedly connected to the front side of the fixing plate 204. The connection of multiple polyurethane foam boards 205 can further improve the heat preservation purpose. A pressure-resistant component 206 is provided on the rear side of the fixing plate 204. The pressure-resistant component 206 includes a carbon fiber board 2061. The front side of the carbon fiber board 2061 is fixedly connected to the rear side of the fixing plate 204. With the cooperation of multiple carbon fiber boards 2061, the pressure resistance of the rear side of the inner wall of the wall 1 can be increased, and the pressure damage on the rear side of the wall 1 can be reduced. Multiple arc-shaped grooves 2062 are equidistantly opened on the rear side of the carbon fiber board 2061.
[0040] Specifically, the insulation mechanism 2 at the bottom of the inner wall of wall 1 is composed of multiple layers of materials, which synergistically enhance the insulation and protection performance of wall 1. The gel board 201, fixed to the front of the inner top wall of wall 1, effectively blocks heat transfer due to its material properties, achieving insulation function. The rock wool board 202 connected to the back of the gel board 201 has multiple fireproof strips 203 fixed on its front and back sides, which enhances the fire resistance of the interior of wall 1 and reduces the risk of fire. The fixing plate 204 on the back of the rock wool board 202 serves as a support component, and multiple polyurethane foam boards 205 fixed on the front further enhance the insulation effect by utilizing their low thermal conductivity. The fixing plate 204 on the back of the fixing plate 204 The compression-resistant component 206, with carbon fiber plate 2061 as its core, is connected to the fixing plate 204 on its front side. Multiple carbon fiber plates 2061, with their high strength characteristics, increase the compression resistance of the rear side of the inner wall of the wall 1 and reduce the damage caused by external pressure to the rear side of the wall 1. Multiple arc-shaped grooves 2062, which are equidistantly opened on the rear side of the carbon fiber plate 2061, further disperse stress through optimized structural design, improve the overall structural stability of the wall 1, and enable the insulation mechanism 2 to achieve efficient insulation while taking into account fire prevention and compression resistance. The weather-resistant mechanism 3 set on the front side of the wall 1 works in conjunction with the insulation mechanism 2 to ensure the performance of the wall 1 from different dimensions.
[0041] Reference Figure 1 , Figure 2 and Figure 5The weather-resistant structure 3 includes a polymer waterproof membrane 301. The rear side of the polymer waterproof membrane 301 is fixedly connected to the front side of the wall 1, which effectively improves the waterproof effect of the structure. A fixed frame 302 is fixedly connected to the front side of the polymer waterproof membrane 301. Multiple high-strength grid plates 303 and connecting grid plates 304 inside the fixed frame 302 can form a rectangular grid structure, thereby improving the impact resistance of the weather-resistant structure 3. Multiple high-strength grid plates 303 are fixedly connected to the left side of the inner wall of the fixed frame 302, and multiple connecting grid plates 304 are fixedly connected to the top inner wall of the fixed frame 302. A fiber cement board 305 is fixedly connected to the front side of the fixed frame 302. The fiber cement board 305 can further improve the strength of the structure and increase its service life. The multiple high-strength grid plates 303 and multiple connecting grid plates 304 are fixedly connected on one side and form a rectangular grid structure.
[0042] Specifically, the polymer waterproof membrane 301 is fixed to the front of the wall 1 from the rear. The dense structure of the polymer material forms a waterproof barrier, effectively preventing water penetration and improving the waterproof performance of the front of the wall 1. The fixing frame 302 on the front of the polymer waterproof membrane 301 serves as a support structure. Multiple high-strength grid plates 303 fixed on the left side of its inner wall and multiple connecting grid plates 304 fixed on the inner top wall are perpendicularly intersected to form a rectangular grid structure. The high strength of the grid plates disperses external impact force, enhances the impact resistance of the weather-resistant mechanism 3, and reduces the damage to the front of the wall 1 caused by external forces. The fiber cement board 305 fixed on the front of the fixing frame 302 uses cement as a matrix and incorporates fiber materials. It has both high strength and weather resistance, further improving the overall structural strength and resisting the erosion of wind, sun and rain in the long-term natural environment. This extends the service life of the weather-resistant mechanism 3 and the wall 1, achieving comprehensive enhancement of waterproof, impact-resistant and weather-resistant functions.
[0043] Reference Figure 1 , Figure 4 and Figure 5 The insulation mechanism 2 also includes a silicone sealing layer 207, the rear side of which is fixedly connected to the front side of the gel plate 201; the bottom wall of the wall 1 is fixedly connected with multiple connecting steel bars 4 at equal intervals, and the top wall of the wall 1 is provided with multiple connecting grooves 5 at equal intervals, the bottom ends of the multiple connecting steel bars 4 respectively engaging with the corresponding connecting grooves 5.
[0044] Specifically, the connection of the silicone sealing layer 207 can effectively increase the sealing of the interior of the wall 1 and reduce the penetration of moisture. By connecting the bottom end of the reinforcing bar 4 to the corresponding connecting groove 5, the connection strength is improved when connecting the wall 1.
[0045] Reference Figure 1 , Figure 2 and Figure 3The weathering mechanism 3 also includes two acrylic coated boards 306, the rear sides of which are fixedly connected to the upper and lower ends of the front side of the fiber cement board 305 respectively; the gel board 201 and the fixing board 204 are at the same height, and the multiple polyurethane foam boards 205 are all designed with equidistant symmetry.
[0046] Specifically, the acrylic coating board 306 can improve the UV resistance of the front side of the wall 1, and the multiple polyurethane foam boards 205 are all designed with equal spacing and symmetry, which improves the uniformity of the thermal insulation effect.
[0047] Working principle: The insulation mechanism 2 at the bottom of the inner wall of wall 1 achieves insulation, fireproofing, and pressure resistance through the synergistic effect of multiple materials. The gel board 201, fixed to the front of the inner top wall of wall 1, effectively blocks heat transfer using its own material properties, initially achieving a heat insulation effect. The rock wool board 202 connected to the back of the gel board 201 has multiple fireproof strips 203 fixed on its front and back sides, which enhance the fire resistance of the interior of wall 1 with their own flame-retardant properties. The fixing plate 204 behind the rock wool board 202 serves as a support structure, and the multiple polyurethane foam boards 205 fixed to its front side further reduce heat conduction due to their extremely low thermal conductivity. The thermal insulation performance of wall 1 is significantly improved. In the compression-resistant component 206 set on the rear side of the fixing plate 204, the front side of the carbon fiber plate 2061 is connected to the fixing plate 204. Multiple carbon fiber plates 2061 increase the compression strength of the rear side of the inner wall of wall 1 with their high strength characteristics, reducing damage caused by external pressure. The arc-shaped grooves 2062 equidistantly opened on the rear side of the carbon fiber plate 2061 effectively disperse stress through optimized structural design, further improving the overall structural stability of wall 1. The various components of the thermal insulation mechanism 2 work together in many aspects, including thermal insulation, fire resistance, and compression stability, to improve the performance of wall 1, reduce building energy consumption, and extend service life.
[0048] Furthermore, the polymer waterproof membrane 301 forms a continuous waterproof barrier through the dense structure of the polymer material, reducing the entry of moisture into the interior of the wall 1. Multiple high-strength grid plates 303 fixed inside the fixing frame 302 are vertically and intersectingly connected with multiple connecting grid plates 304 to form a rectangular grid structure. The high strength of the grid plates disperses external impact forces, improving the impact resistance of the front side of the wall 1 and reducing damage to the wall 1 from external impacts. The fiber cement board 305 fixed to the front side of the fixing frame 302, with cement as the base material and fiber reinforcement material, has high strength and weather resistance, further enhancing the structural strength of the front side of the wall 1, resisting natural environmental erosion, and extending the service life of the wall 1. Through the synergistic effect of waterproof barrier, impact dispersion and structural reinforcement, the various components achieve comprehensive protection for the wall 1.
