Description

Technical Field

[0001] This invention relates to the field of building decoration technology, and more specifically, to a method for constructing facing bricks based on a cement board substrate. Background Technology

[0002] Ordinary brick walls are a commonly used building material in construction, possessing advantages such as simple construction, convenient installation, and low cost. They are widely used in civil, commercial, and public buildings. Ordinary brick walls use ordinary red bricks, and the construction method includes the following steps: At the construction site, accurate measurements are first taken using a level and chalk line to draw a plan of the wall and floor. Then, the bricks are grouped. Before starting to lay the wall, the bricks are classified according to size, shape, and color to ensure that there are no inconsistencies in color or mismatched brick sizes, greatly reducing the number of adjustments and corrections and improving efficiency. Finally, after installing the building fasteners, the wall is laid. Summary of the Invention

[0003] In view of this, the present invention proposes a method for constructing facing bricks based on a cement board base, which aims to solve the problem of the cumbersome and inefficient construction of existing wall bricks that require brick-by-brick transfer.

[0004] This invention proposes a method for constructing facing bricks based on a cement board substrate. The method includes: using a light steel keel as the framework and cement board as the wall panel; cleaning and caulking the cement board substrate; applying an interface agent to the cleaned and caulked cement board surface to form an interface agent layer; applying mortar to the interface agent layer based on the wall leveling thickness to form a cement board leveling layer, ensuring the overall flatness and verticality of the wall meet preset requirements; applying a waterproof coating to the cement board leveling layer to form a waterproof layer; and using an adhesive mortar to lay the facing bricks on the waterproof layer, and caulking the gaps between the facing bricks with a grout.

[0005] Furthermore, in the above-mentioned method for constructing facing bricks based on cement board substrates, when cleaning and caulking the cement board substrate: first, the cement board substrate is cleaned to remove surface debris; then, the nail holes on the surface of the cement board are covered with cement slurry; finally, the joints of the boards are caulked with crack-resistant mortar, and a layer of fiberglass mesh is pressed inside during the caulking process.

[0006] Furthermore, in the above-mentioned method for constructing facing bricks based on cement board substrates, when using an interface agent to fill the joints of the boards and pressing a layer of fiberglass mesh into the joints: the joint filling is completed in three steps. First, the joints of the cement board are filled with crack-resistant mortar, and the mesh is embedded in the mortar, and then covered with crack-resistant mortar to ensure that the finished surface is flush with the surface of the cement board. Second, after the first layer of crack-resistant mortar has solidified and dried completely, a second layer of crack-resistant mortar is applied to the surface. The second layer of crack-resistant mortar is 50mm wider on each side than the first layer, and the width of each side is greater than or equal to 200mm. Third, after the second layer of crack-resistant mortar has solidified and dried completely, a third layer of crack-resistant mortar is applied to the surface. The third layer should be 50mm wider on each side than the second layer, and the width of each side is greater than or equal to 300mm. The surface is smoothed and finished before the third layer of mortar is completely dry.

[0007] Furthermore, the above-mentioned method for constructing facing bricks based on a cement board substrate, wherein the adhesive slurry formed by mixing adhesive is used to lay the facing bricks on the waterproof layer, and the gaps between the facing bricks are filled with grout, includes: before construction, marking elevation control lines around the perimeter of the wall and pre-laying the facing bricks with reference to the elevation control lines; first adding water to the mixing bucket, then adding adhesive, and using a mixer to mix the two evenly until creamy, letting it stand for 5-10 minutes after mixing, and then mixing again to obtain the adhesive slurry; the water and adhesive... The mixing ratio is 25%~27%; for formal tiling, first use the straight edge of a notched trowel to forcefully scrape a thin layer of the mixed adhesive slurry onto the base surface, and then use the notched edge of the trowel to comb the adhesive slurry into even, straight stripes on the base surface; after the wall tiles have dried, grout them; first grout the horizontal joints, then the vertical joints, and the grouting depth should be 1mm below the surface of the wall tiles; when grouting the wall tiles, wipe the mortar off the surface of the wall tiles with a cotton cloth; 10 days after grouting, use a neutral detergent or a 20% concentration of dilute hydrochloric acid to clean any remaining dirt, and then rinse with clean water.

[0008] Furthermore, in the above-mentioned method of constructing facing bricks based on cement board substrate, when laying the bricks, a layer of adhesive slurry is vigorously scraped onto the back of the facing brick material larger than 200mm*200mm, the facing brick material is then pasted on, and it is pressed firmly, or a tool is used to completely adhere the facing brick material to the waterproof layer.

[0009] Furthermore, in the above-mentioned method for constructing facing bricks based on cement board substrates, the facing brick material is pasted on before the adhesive that has been applied and combed into stripes has formed a film and is sticky to the touch during the actual brick laying. If the adhesive has already formed a film, the adhesive slurry is applied again and the stripes are combed.

[0010] Furthermore, in the above-mentioned method for constructing facing bricks based on cement board substrates, gaps are left when the facing bricks are pasted during the actual tiling process. During construction, plastic cross clips are selected to control the gap width according to the gap width, and plastic clips are set at each cross intersection. The facing bricks in the same segment or block are all laid from bottom to top. A straightedge is placed at the bottom edge of the second-to-last row of facing bricks to support the second row of facing bricks, and a horizontal line is drawn on the top edge of the facing bricks as the standard for laying.

[0011] Furthermore, the above-mentioned method for constructing facing bricks based on cement board substrates, wherein the step of applying an interface agent to the surface of the cement board after cleaning and joint treatment, and forming an interface agent layer on the cement board surface, includes: after performing nail hole rust prevention treatment and joint filling treatment on the cement board surface, cleaning the cement board surface again; preparing the interface agent and stirring it with an electric device until a uniform slurry is formed, obtaining an interface agent slurry; wherein the ratio of water to interface agent dry powder is 0.5:1; applying the uniformly stirred interface agent slurry to the cement board surface using a roller or brush; simultaneously performing roughening treatment during the brushing process; and curing after the interface agent is applied.

[0012] Furthermore, the above-mentioned method for constructing facing bricks based on a cement board substrate, wherein the mortar is applied to the interface agent layer based on the wall leveling thickness to form a cement board leveling layer to ensure that the overall flatness and verticality of the wall meet the preset requirements, includes: after the coating surface dries, using a 1:2 dry-hardened cement mortar to create mortar spots on the interface agent surface; according to the mortar mixing ratio, water is first added to the mixing bucket, and crack-resistant mortar is used, with uniform mixing while adding the crack-resistant mortar, the water-to-mortar ratio being 1:2.5, and the mortar consistency not exceeding 35mm; after the mortar is completely added, mechanical mixing is used, and the mixing time after the addition is greater than or equal to 2 seconds. Minutes; using a suitable trowel, apply the well-mixed mortar to the wall surface. The number of coats depends on the desired leveling thickness, ensuring the overall flatness and verticality of the wall meet requirements. Allow 2-3 hours between coats. For the final coat, level and compact the mortar, filling and smoothing any pits or sand holes to ensure a smooth surface. Depending on the ambient temperature, spray water on the mortar surface within 24 hours of completion to keep it moist. Only proceed with subsequent waterproofing work after the surface is completely dry.

[0013] Furthermore, the above-mentioned method for constructing facing bricks based on cement board substrate, wherein the waterproof coating is rolled onto the cement board leveling layer to form a waterproof layer, includes: using polymer cement waterproof coating for wall waterproofing, preparing it according to its preset configuration requirements, the waterproof coating including liquid and powder, the liquid and powder being mixed in a required ratio of 1:1.2; rolling the waterproof coating, the thickness of the waterproof coating layer being greater than or equal to 1.5mm.

[0014] This invention provides a method for constructing facing bricks based on a cement board substrate. Using a light steel keel as the framework, cement board as the wall panel, and facing bricks as the facing material, a lightweight partition wall is formed. The construction method includes cement board substrate treatment, wall surface coating with an interface agent, wall mortar leveling, waterproofing layer construction, and laying of facing bricks. Compared to ordinary brick wall construction methods, this method offers numerous advantages, including reduced building energy consumption, better seismic performance, improved stability, and guaranteed project quality, making it highly worthy of widespread application. This construction method optimizes traditional brick wall laying, improving construction efficiency, reducing building energy consumption, enhancing seismic performance, and ensuring project quality. It solves the problem of the tedious and inefficient process of bricklaying, which requires transferring bricks one by one. Furthermore, this lightweight partition wall, due to its light weight, thin wall body, easy assembly and disassembly, and flexible design, can be widely used in interior decoration design and construction. In addition, this method also has the following effects:

[0028] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0029] See Figures 1 to 2 This figure illustrates the process of a method for constructing facing bricks based on a cement board substrate, as provided in an embodiment of the present invention. As shown, the construction method includes the following steps:

[0030] The construction steps for the cement board base layer are as follows: S1, light steel keel is used as the framework, cement board is used as the wall panel, and the cement board base layer is cleaned and caulking is performed.

[0031] Specifically, such as Figure 3 As shown, light steel keel can be used as the framework in building 1, and cement board 2 can be used as the wall panel to complete the construction of the wall as a whole. The cement board base is cleaned and caulking is performed. When cleaning and caulking the cement board base, the cement board base, namely cement board 2, can be cleaned first to remove surface debris. For example, a clean broom can be used to clean the cement board base, namely cement board 2, to remove surface dust, water stains, etc. Then, cement slurry is used to cover the nail holes on the surface of the cement board to prevent rust. Finally, crack-resistant mortar is used to caulking the joints of the boards, and a layer of fiberglass mesh is pressed inside during the caulking process.

[0032] Specifically, when using an interface agent to caulking the joints of the cement board, and embedding a layer of fiberglass mesh during the caulking process, the caulking can be completed in three steps as required. First, fill the joints of the cement board with crack-resistant mortar, embedding the mesh, and then cover with more crack-resistant mortar, ensuring the finished surface is flush with the cement board surface. The width of the first layer of crack-resistant mortar should be 100mm. Second, after the first layer of crack-resistant mortar has solidified and dried completely, apply a second layer of crack-resistant mortar. The second layer should be 50mm wider on each side than the first layer, and each side should be at least 200mm wide. Third, after the second layer of crack-resistant mortar has solidified and dried completely, apply a third layer of crack-resistant mortar. The third layer should be 50mm wider on each side than the second layer, and each side should be at least 300mm wide. Smooth and finish the surface before the third layer of mortar is completely dry. The crack-resistant mortar can be DP-HR crack-resistant mortar.

[0033] In step S2 of the interface agent application, an interface agent is rolled onto the surface of the cement board after cleaning and joint treatment to form an interface agent layer on the surface of the cement board.

[0034] Specifically, after cleaning the surface of the cement board and treating the joints in step S1, an interface agent, i.e., an interface agent slurry, is rolled onto the surface of the cement board 2. After the interface agent slurry dries, an interface agent layer 3 is formed on the surface of the cement board 2.

[0035] In cement board leveling step S3, based on the wall leveling thickness, mortar is applied to the interface agent layer to form a cement board leveling layer, ensuring that the overall flatness and verticality of the wall meet the preset requirements.

[0036] Specifically, based on the wall leveling thickness, mortar is applied onto the interface agent layer 3 to form a cement board leveling layer 4, ensuring that the overall flatness and verticality of the wall meet the preset requirements. The number of mortar applications can be determined based on the wall leveling thickness. Depending on the ambient temperature, the mortar surface is sprayed with water within 24 hours of completion to keep it moist and prevent cracking. The next step of waterproofing construction can only proceed after the surface is completely dry.

[0037] Waterproofing construction step S4: Apply the waterproof coating to the cement board leveling layer by roller to form a waterproof layer.

[0038] Specifically, after the cement board leveling layer 4 is completely dry, the waterproof coating is rolled onto the cement board leveling layer to form the waterproof layer 5. For areas such as pipes penetrating the external wall, embedded parts, and door and window openings, reinforcement treatment should be applied, ensuring that the coating extends upwards by at least 300mm. The surface of the waterproof coating should be smooth and uniform, free from defects such as drips, exposed substrate, bubbles, wrinkles, and curling edges. According to the drawings, the thickness of the waterproof layer 5 should not be less than 1.5mm, that is, the thickness of the waterproof layer 5 is greater than or equal to 1.5mm.

[0039] In step S5, the tiling bricks are laid on the waterproof layer using an adhesive mortar formed by mixing adhesives, and the gaps between the tiling bricks are filled with grout.

[0040] Specifically, an adhesive mortar is formed by mixing adhesives, and the facing bricks are laid on the waterproof layer 5, forming a facing brick layer 7. An adhesive layer 6, formed by the solidified adhesive mortar, is then created between the waterproof layer 5 and the facing brick layer 7. Grout is then used to fill the gaps between the facing bricks. Before laying the wall tiles, a layout plan needs to be developed. The layout principles are as follows: In general, bricks should be laid from the doorway in whole bricks towards the interior, symmetrically centered. If there are columns or column grids, the joints should be centered. Wall tiles should not contain narrow bricks less than 1 / 3 of their length. Non-whole bricks should be placed in secondary areas at the ends of the wall or in corners. Materials with the same width module should be used for both walls and floors to ensure continuous and seamless joints.

[0041] See Figure 4 This is a flowchart of the interface agent application steps provided in an embodiment of the present invention. As shown in the figure, interface agent application step S2 includes the following sub-steps:

[0042] Step S21, cleaning the cement board surface, involves cleaning the cement board surface again after treating the nail holes for rust prevention and caulking the joints. Specifically, after treating the nail holes for rust prevention and caulking the joints, repeat step one to clean the cement board surface again, ensuring it is clean, free of loose parts, dust, and grease. The construction environment must be dry, with a relative humidity of less than 70%, and should be well-ventilated. The temperature of the cement board substrate and the surrounding environment should not be lower than 5°C; otherwise, heating measures must be taken.

[0043] In step S22, the interface agent is prepared by stirring with an electric mixer until a uniform slurry is formed, resulting in an interface agent slurry. The ratio of water to interface agent dry powder is 0.5:1. Specifically, the preparation must be strictly in accordance with the interface agent preparation requirements. For each 20 kg bag of powder, add 10 liters of water, i.e., water: interface agent dry powder = 0.5:1. Stirring must be performed using an electric mixer until a uniform slurry is achieved.

[0044] Step S23: Apply the interface agent by roller or brush, using a roller or brush to apply the well-mixed interface agent slurry to the surface of the cement board. During the application process, simultaneously roughen the surface. Specifically, use a roller or brush to apply the well-mixed slurry to the surface of the cement board, brushing in sequence to ensure no areas are missed. Note that during the application process, roughen the surface to prepare for subsequent mortar application. After application, keep the coated surface dry for approximately 12 hours.

[0045] Step S24 is the curing process after the interface agent is applied. Specifically, after applying the interface agent, adequate ventilation is required, and natural curing is sufficient. Only after the coated surface is completely dry (appearing grayish-black) can subsequent mortar leveling be carried out.

[0046] See Figure 5 This is a structural schematic diagram of the cement board leveling step provided in an embodiment of the present invention. As shown in the figure, the cement board leveling step S3 includes the following sub-steps:

[0047] Step S31: After the coated surface has dried, use a 1:2 dry-hardened cement mortar to create mortar patches on the interface agent surface. Specifically, to ensure a smooth surface for the subsequent mortar leveling, use a 1:2 dry-hardened cement mortar to create mortar patches approximately 50mm in size, square in shape, with a horizontal spacing of 1.5m to facilitate mortar leveling.

[0048] In mortar mixing sub-step S32, according to the mortar mix ratio, first add water to the mixing bucket. Use crack-resistant mortar, adding it while simultaneously stirring evenly. The water-to-mortar ratio is 1:2.5, and the mortar consistency should not exceed 35mm. After the mortar is completely added, use mechanical stirring, with a stirring time of at least 2 minutes after all materials have been added. Specifically, according to the mortar mix ratio requirements, first add clean water to a clean mixing bucket. Use dedicated crack-resistant mortar, adding it while simultaneously stirring evenly. The water-to-mortar ratio is 1:2.5 (by volume), and the mortar consistency should not exceed 35mm. After all materials have been added, use mechanical stirring, with a stirring time of at least 2 minutes after all materials have been added to ensure uniform mixing, free from lumps, color differences, and large gravel. Note that the mixed mortar must be used within 1 hour to prevent solidification.

[0049] In mortar plastering step S33, using a suitable trowel, apply the evenly mixed mortar to the wall surface. The number of coats depends on the desired leveling thickness, ensuring the overall flatness and verticality of the wall meet requirements. Allow 2-3 hours between coats. The final coat of mortar should be used for overall leveling and compaction, filling and smoothing any pits or sand holes to ensure a smooth surface. Depending on the ambient temperature, spray water on the mortar surface within 24 hours of completion to keep it moist. Only proceed with subsequent waterproofing work after the surface is completely dry. Specifically, the overall flatness and verticality must meet requirements. A 2-3 hour interval is required between coats. The final coat of mortar should be used for overall leveling and compaction, filling and smoothing any pits or sand holes to ensure a smooth surface. Depending on the ambient temperature, the surface of the mortar should be sprayed with water within 24 hours of completion to keep it moist and prevent cracking. The next step of waterproofing construction can only be carried out after the surface is completely dry.

[0050] See Figure 6 This is a flowchart of the waterproofing construction steps provided in an embodiment of the present invention. As shown in the figure, waterproofing construction step S4 includes the following sub-steps:

[0051] In step S41, the wall waterproofing uses polymer cement waterproofing coating, which is prepared according to its preset configuration requirements. The waterproofing coating includes liquid and powder components, which are mixed in a required ratio of 1:1.2. Specifically, the wall waterproofing uses polymer cement waterproofing coating, which is prepared according to its configuration requirements. This type of waterproofing consists of liquid and powder components, which are mixed in a required ratio of 1:1.2 to ensure uniform mixing and no lumps.

[0052] In step S42, the waterproof coating is applied by roller, with a thickness of 1.5mm or more. Specifically, the waterproof coating should be applied in sequence to form waterproof layer 5. For areas such as pipes penetrating external walls, embedded parts, and door / window openings, reinforcement treatment should be applied, extending upwards by at least 300mm. The surface of the waterproof coating should be smooth, uniform, and free from defects such as drips, exposed substrate, bubbles, wrinkles, and curling edges. According to the drawings, the thickness of the waterproof coating should not be less than 1.5mm.

[0053] See Figure 7 This is a flowchart of the brick-laying steps provided in an embodiment of the present invention. As shown in the figure, brick-laying step S5 includes the following sub-steps:

[0054] Step S51: Before construction, mark the elevation control lines around the perimeter of the wall and pre-lay the facing bricks according to these lines. Specifically, before formal tiling, the facing bricks should be rigorously selected based on the design drawings, considering factors such as color, texture, and surface smoothness. Before construction, mark the elevation control lines around the perimeter of the wall (based on the 1000mm line on the wall). Refer to the control lines marked on-site and pre-lay the bricks according to the drawings to achieve the best effect. The facing bricks should be neatly stacked in the tiling sequence and ready for use. Generally, there should be no broken bricks or bricks smaller than half a brick; try to place half-bricks on surfaces that are not directly visible.

[0055] In material preparation sub-step S52, first add water to the mixing bowl, then add the adhesive. Use a mixer to mix the two until they reach a creamy consistency. After mixing, let it stand and mature for 5-10 minutes, then mix again to obtain an adhesive slurry. The water-to-adhesive ratio is 25%-27%. Specifically, the water-to-adhesive ratio is approximately 25%-27% (one 25kg bag of high-performance multi-functional adhesive is mixed with approximately 6.25-6.75kg of water). First, add a certain amount of water to a clean mixing bowl, then add an appropriate amount of adhesive. Use a low-speed electric mixer to mix the two until they reach a creamy consistency. After mixing, let it stand and mature for 5-10 minutes, then mix slightly before use. The prepared material should be used within 2 hours.

[0056] Step S53 for laying facing tiles: For the actual tile laying, use the straight edge of a notched trowel to firmly scrape a thin layer of the mixed adhesive mortar onto the substrate, then use the notched edge of the trowel to comb the adhesive mortar into even, straight stripes on the substrate. Specifically, for the actual tile laying, first use the straight edge of a notched trowel to firmly scrape a thin layer of the mixed adhesive mortar onto the substrate, then use the notched edge of the trowel to comb an appropriate amount of mortar into even, straight stripes on the substrate. For large-sized facing tiles (larger than 200mm*200mm), a layer of adhesive needs to be firmly scraped onto the back before pasting the facing tile, pressing firmly, or using a rubber mallet, vibrator, or other tools to completely adhere the facing tile. Note: Facing tile pasting should be completed before the applied and combed adhesive has formed a film and is tacky to the touch. If it has already formed a film (is not tacky), fresh mortar needs to be applied again and the stripes combed. When installing wall tiles, a 2mm gap must be left. During installation, select appropriate plastic cross clips according to the gap width, and place plastic clips at each cross intersection. Tiles within the same section or block should be installed from bottom to top. Place a straightedge at the bottom edge of the second-to-last row of tiles to support it, and use a horizontal line drawn along the top edge of the tiles as a standard for installation.

[0057] Step S54 of the grouting process involves grouting the walls after the tiles have dried. First, grout the horizontal joints, then the vertical joints, with the grout depth 1mm below the surface of the tiles. While grouting, wipe the mortar off the tile surface with a cotton cloth. Ten days after grouting, use a neutral detergent or a 20% diluted hydrochloric acid solution to clean any remaining dirt, then rinse thoroughly with clean water. Specifically, grouting should be done approximately 24 hours after the tiles have dried. Use the grout color selected by the homeowner, grouting the horizontal joints first, then the vertical joints, with the grout depth approximately 1mm below the surface of the tiles. Wipe the mortar off the tile surface with a cotton cloth immediately after grouting. More than 10 days after grouting, use a neutral detergent or a 20% diluted hydrochloric acid solution to clean any remaining dirt, then rinse thoroughly with clean water.
