Description

Technical Field

[0001] This utility model relates to the field of exterior wall brick technology, specifically to a nano-hydrophobic building exterior wall brick. Background Technology

[0002] Building exterior wall bricks refer to building materials used for the decoration and protection of building exteriors. They possess multiple attributes such as decorativeness, functionality, and durability, and are widely used on the exterior surfaces of various buildings, including residential, commercial, and public facilities. However, a drawback is that while adding nano-hydrophobic materials (usually liquid) to the brick raw materials can extend their service life, the large amount of these materials used leads to higher costs. Furthermore, uneven mixing can result in areas lacking hydrophobic properties. To address these shortcomings, existing technology (application number: 201821925414.5, authorized announcement) provides solutions. (Chinese patent dated November 19, 2019) Nano-hydrophobic building exterior wall bricks feature hemispherical protrusions on the outer surface of the brick substrate. These protrusions serve to guide the installation, ensuring that the bricks are laid facing outwards to avoid incorrect orientation. The nano-hydrophobic layer is applied only to the outer surface of the brick substrate and the hemispherical protrusions, significantly reducing the amount of nano-hydrophobic material used and further simplifying manufacturing. This avoids uneven mixing that could lead to localized lack of hydrophobic function. The mesh grooves guide excess nano-material during the processing of the hydrophobic layer and further enhance the hydrophobic properties of the surrounding area.

[0003] Existing technologies improve hydrophobicity by applying a hydrophobic layer of nanomaterials to the outer surface of the exterior wall brick substrate and on hemispherical protrusions. However, this hydrophobic layer may gradually fail, at which point rainwater on the wall surface cannot be discharged through active drainage paths. It is easy for water to accumulate in the brick joints and uneven interfaces, seeping into the interior of the wall and causing mold, freeze-thaw damage, and insufficient drainage efficiency. Furthermore, traditional adhesive or dry-hanging processes for exterior wall bricks require individual calibration and positioning, relying on adhesives or keels for fixation. This results in a long construction cycle and high skill requirements for workers. Therefore, we proposed nano-hydrophobic building exterior wall bricks, which can effectively solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a nano-hydrophobic building exterior wall tile to solve the problem mentioned in the background art that the hydrophobic layer may gradually fail. At this time, rainwater on the wall surface cannot be discharged through the active drainage path, and it is easy to form a water film in the brick joints and uneven interfaces, which can penetrate into the interior of the wall and cause mold and freeze-thaw damage, resulting in insufficient drainage efficiency. In addition, the traditional pasting or dry hanging process for exterior wall tiles requires each tile to be calibrated and positioned, and relies on adhesives or keels for fixation, which results in a long construction cycle and high technical requirements for workers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nano-hydrophobic building exterior wall brick, comprising a brick body, wherein a locking block and a locking groove are respectively provided on the outer side of the brick body, and water guiding grooves are equally spaced on the surface of the brick body; further comprising: a protrusion fixed on the side of the locking block, a deep groove being provided inside the brick body on the side of the locking groove, and a limiting block being provided on the inner wall of the deep groove, a return spring being installed between the end of the limiting block and the inner wall of the deep groove, and a water-draining rod being fixedly connected at equal intervals on the surface of the brick body between every two water guiding grooves.

[0006] Preferably, the card block and the card slot are arranged in an "L" shape, and the card block and the card slot are connected by an interlocking mechanism, and adjacent bricks are assembled together by the card block and the card slot.

[0007] Preferably, the limiting block is slidably disposed on the inner wall of the deep groove, and the end of the limiting block away from the reset spring extends into the interior of the slot, and the protrusion is in contact with the end of the limiting block.

[0008] Preferably, the hydrophobic rod and the water guide groove are both vertically arranged on the surface of the brick, and a transition layer is bonded to the outer surface of the brick, and the side of the transition layer away from the brick is coated with a nano-hydrophobic coating.

[0009] Preferably, an air layer is provided in the middle of the brick body, and a sound insulation layer is provided on one side of the air layer inside the brick body, and a heat insulation layer is connected to the other side of the air layer inside the brick body.

[0010] Preferably, the sound insulation layer is made of rock wool, and the thermal insulation layer is made of EPS polystyrene board.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the nano-hydrophobic building exterior wall brick adopts a novel structural design, the specific details of which are as follows:

[0012] (1) By designing multiple water-guiding channels on the surface of the brick, a directional drainage path is formed, which quickly guides rainwater from the brick surface to the bottom of the exterior wall, reducing the retention time of water on the brick surface and in the gaps. At the same time, the installed water-draining rods can quickly guide rainwater to the interior of the water-guiding channels, preventing water from spreading on the brick surface. Furthermore, a nano-hydrophobic coating is set on the surface of the brick, which can form a hydrophobic barrier, and the transition layer can buffer external impacts and prevent damage to the nano-hydrophobic coating structure.

[0013] (2) Adjacent bricks are quickly assembled together by L-shaped blocks and slots, which facilitates construction. When the blocks are inserted into the slots, the protrusions on the blocks will squeeze the limiting blocks, causing them to move. When the protrusions move from one side of the limiting blocks to the other side, the limiting blocks are reset by the spring force of the reset spring and block the protrusions, thus generating effective constraint forces in both the horizontal and vertical directions, ensuring that the bricks remain stable under loads such as wind pressure and vibration.

[0014] (3) The sound insulation layer can absorb sound waves and reduce the amount of sound transmitted through the wall to achieve the purpose of noise reduction. The heat insulation layer can significantly reduce the heat transfer coefficient of the wall, which can reduce the thermal expansion and contraction stress of the main structure caused by temperature changes and extend the service life of the building. At the same time, the air layer set inside the brick can utilize the low thermal conductivity and convection characteristics of air to form a dynamic heat buffer layer. When combined with the heat insulation layer, it can form a "static air heat insulation layer" to further enhance thermal resistance. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] Please see Figures 1-6 The present invention provides the following technical solution: a nano-hydrophobic building exterior wall brick;

[0024] Example 1: To address the issue that in existing technologies, the hydrophobic layer may gradually fail, preventing rainwater from draining through active drainage paths. This leads to the formation of stagnant water films at brick joints and uneven surfaces, which can seep into the wall, causing mold growth and freeze-thaw damage, resulting in insufficient drainage efficiency. Furthermore, traditional adhesive or dry-hanging methods for exterior wall tiles require individual alignment and positioning, relying on adhesives or joists for fixation, resulting in long construction cycles and high skill requirements for workers. Therefore, the following solution is disclosed for reference. Figures 1-4 and Figure 6 As shown, it includes a brick body 1, with a locking block 2 and a locking groove 3 respectively provided on the outer side of the brick body 1, and water guiding grooves 8 are opened at equal intervals on the surface of the brick body 1; it also includes: the locking block 2 and the locking groove 3 are arranged in an "L" shape, and the locking block 2 and the locking groove 3 are connected by an interlocking connection, and adjacent brick bodies 1 are assembled together by the locking block 2 and the locking groove 3. A water-draining rod 7 is fixedly connected at equal intervals between every two water guiding grooves 8 on the surface of the brick body 1. The water-draining rod 7 and the water guiding groove 8 are both arranged vertically on the surface of the brick body 1. A transition layer 9 is bonded to the outer surface of the brick body 1, and the side of the transition layer 9 away from the brick body 1 is coated with a nano hydrophobic coating 10.

[0025] By designing multiple water-guiding channels 8 on the surface of the brick body 1, a directional drainage path is formed, which quickly guides rainwater from the brick surface to the bottom of the exterior wall, reducing the retention time of water on the brick surface and in the gaps. At the same time, the installed water-draining rods 7 can quickly guide rainwater into the interior of the water-guiding channels 8, preventing water from spreading on the brick surface. Furthermore, by applying a nano-hydrophobic coating 10 to the surface of the brick body 1, a hydrophobic barrier can be formed, and the transition layer 9 can buffer external impacts and prevent damage to the nano-hydrophobic coating 10 structure. Then, adjacent brick bodies 1 can be quickly joined together by inserting L-shaped clips 2 into the clip slots 3, which facilitates construction.

[0026] Example 2: Unlike Example 1, this example uses a limiting block 5 to block and limit the protrusion 4, which can generate effective restraint force in both the horizontal and vertical directions, ensuring that the brick 1 remains stable under loads such as wind pressure and vibration. See details... Figure 2 , Figure 3 and Figure 5As shown, a protrusion 4 is fixed on the side of the card block 2. A deep groove is opened inside the brick body 1 on the side of the card slot 3. A limit block 5 is provided on the inner wall of the deep groove. A reset spring 6 is installed between the end of the limit block 5 and the inner wall of the deep groove. The limit block 5 is slidably disposed on the inner wall of the deep groove. The end of the limit block 5 away from the reset spring 6 extends into the interior of the card slot 3. The protrusion 4 is in contact with the end of the limit block 5.

[0027] When the L-shaped locking block 2 is precisely inserted into the locking slot 3, the end of the protrusion 4 will press against the limiting block 5, forcing the limiting block 5 to overcome the preload of the return spring 6 and slide horizontally along the deep groove. When the protrusion 4 passes the highest point of the limiting block 5, the return spring 6 releases its elastic force instantly, driving the limiting block 5 to reset and block and limit the protrusion 4, thereby generating effective constraint force in both the horizontal and vertical directions, ensuring that the brick 1 remains stable under loads such as wind pressure and vibration.

[0028] Example 3: Unlike Example 2, this example utilizes a sound insulation layer 11 and a heat insulation layer 13 to achieve both noise reduction and heat preservation. See details below. Figure 6 As shown, an air layer 12 is provided in the middle of the interior of the brick body 1, and a sound insulation layer 11 is provided on one side of the air layer 12 inside the brick body 1, and a heat insulation layer 13 is connected to the other side of the air layer 12 inside the brick body 1. The sound insulation layer 11 is made of rock wool material, and the heat insulation layer 13 is made of EPS polystyrene board material.

[0029] The sound insulation layer 11 absorbs sound waves and reduces the amount of sound transmitted through the wall, thus achieving noise reduction. The thermal insulation layer 13 significantly reduces the heat transfer coefficient of the wall, which can reduce the thermal expansion and contraction stress caused by temperature changes in the main structure and extend the service life of the building. At the same time, the air layer 12 set inside the brick body 1 can utilize the low thermal conductivity and convection characteristics of air to form a dynamic thermal buffer layer. When combined with the thermal insulation layer 13, it can form a "static air insulation layer" to further enhance thermal resistance.
