Description

Technical Field

[0001] The present application relates to the technical field of stone-like paint construction, and in particular to a deep groove construction process of stone-like paint based on a thermal insulation layer. Background Art

[0002] In wall decoration projects, in order to improve the beauty and durability of buildings, people are increasingly choosing to use imitation stone paint instead of dry hanging stone. Imitation stone paint is gradually gaining popularity in the market because of its appearance comparable to stone, convenient and fast construction, and low cost. At present, when implementing the imitation stone paint construction process, flat seam process or deep groove process is often used.

[0003] The flat seam process refers to a Chinese patent document with publication number CN101319552A, which discloses a method for constructing exterior walls of buildings with real stone paint imitating facing bricks. The exterior wall is used as the base surface, and the exterior wall base is coated and polished flat with putty. A primer layer is placed on it with a primer, and then elastic grids are made on the primer layer. Masking paper strips are elastically pasted according to the grids. After that, imitation stone paint is sprayed. After spraying, the masking paper strips are torn off in time, and decorative grooves are left at the paper strips. Finally, one side of the topcoat is sprayed.

[0004] The deep groove process refers to the Chinese patent document with publication number CN113062544A, which discloses a stone-like paint groove construction process, which involves installing a concave metal strip on the wall and applying putty on the wall for priming and leveling, with a putty layer thickness of 4 to 6 mm; then spraying the stone-like paint.

[0005] Among them, the flat seam process has thin separation seams and is difficult to control the flatness, so the imitation stone effect is poor, while the deep groove process has better appearance and flatness. However, when there is a wall decoration of the insulation layer on the exterior wall, the outer surface of the insulation layer has requirements for hanging weight, and the putty leveling layer of the deep groove process is thicker, which is easy to affect the stability of the insulation layer. Summary of the invention

[0006] In order to improve the stability of the thermal insulation layer when it is decorated with imitation stone paint, the present application provides a deep groove construction process of imitation stone paint based on the thermal insulation layer.

[0007] The present application provides a stone-like paint deep groove construction process based on an insulation layer, which adopts the following technical solutions: A stone-like paint deep groove construction process based on an insulation layer comprises the following steps: Install the insulation layer, and install multiple insulation boards on the wall surface in sequence to form an insulation layer; Open the concave dividing grooves and groove the surface of the insulation board according to the designed grid size; Embed the process strips, embed the process strips with grooves into the separation grooves on the surface of the insulation board, so that the grooves of the process strips face the external environment of the insulation board, and the side of the process strips away from the wall protrudes from the outer surface of the insulation board, and the sides of the process strips on the same insulation board away from the wall are flush; Scrape the leveling layer and use the leveling slurry to scrape the surface of the insulation board. Use the side of the process strip away from the insulation board as the reference point for the flatness of the leveling slurry, so that the finished surface of the leveling layer is flush with the side of the process strip away from the wall; Spray the imitation stone paint layer, and spray paint on the finished surface of the leveling layer and the grooves of the process strips.

[0008] By adopting the above technical solution, by directly grooving and inlaying process strips on the surface of the insulation board, the insulation board can be used as a part of the imitation stone board, that is, the thickness of the leveling layer can be reduced, thereby reducing the weight of the leveling layer and improving the stability of the insulation layer. At the same time, through the reference role of the process strips, the flatness of the scraping and leveling can be indicated to improve the flatness of the leveling layer.

[0009] Optionally, in the step of installing the insulation layer, the insulation board is adhered to the wall surface by bonding mortar; before the step of scraping the leveling layer, it also includes: installing anchors, and the anchors fix the insulation board to the wall with no less than 6 anchors / ㎡.

[0010] By adopting the above technical solution, by using a combination of bonding mortar and anchors when installing the insulation layer, the connection strength between the insulation board and the wall is enhanced, the risk of the insulation layer falling off is further reduced, and the safety and reliability of the overall construction are improved.

[0011] Optionally, in the step of installing the insulation layer, the upper and lower layers of the insulation board are staggered; and in the step of opening the concave dividing groove, the dividing groove is staggered with the edge line of the insulation board.

[0012] By adopting the above technical solution, through the staggered distribution of the upper and lower layers of the insulation board and the staggered distribution of the dividing groove and the edge line of the insulation board, the cracking problem caused by stress concentration at the joints of the insulation boards is reduced, and the overall strength and durability of the insulation layer are improved.

[0013] Optionally, in the step of applying the leveling layer, the leveling slurry includes anti-cracking mortar and putty material, wherein the anti-cracking mortar is first applied to the surface of the insulation board, and after the anti-cracking mortar is dried, the putty material is applied on the anti-cracking mortar and leveling is performed.

[0014] By adopting the above technical scheme, the leveling slurry adopts a combination of anti-cracking mortar and putty material, which not only improves the anti-cracking performance of the leveling layer, but also enhances the flatness and adhesion of the leveling layer, providing a good foundation for the subsequent spraying of the imitation stone paint layer.

[0015] Optionally, when applying anti-cracking mortar on the surface of the insulation board, first apply the base anti-cracking mortar, then press the mesh cloth on the base anti-cracking mortar, and then scrape the surface anti-cracking mortar and completely cover the mesh cloth.

[0016] By adopting the above technical solution, mesh cloth is pressed into the anti-cracking mortar to form a double anti-cracking layer, which further improves the anti-cracking ability and durability of the leveling layer and further ensures the stability and service life of the insulation layer.

[0017] Optionally, two opposite sides of the process strip are provided with mesh cloth extending to the surface of the insulation board, and the mesh cloth pressed onto the bottom anti-cracking mortar overlaps with the mesh cloth on the process strip.

[0018] By adopting the above technical solution, the mesh cloth on the process strip is overlapped with the mesh cloth on the bottom anti-cracking mortar, so that the continuous distribution of the mesh cloth on the surface of the insulation board is achieved, the leveling layer is not prone to damage due to crack expansion, and the overall construction quality is improved.

[0019] Optionally, before the step of spraying the imitation stone paint layer, the step also includes: cleaning the process strips, tearing off the protective film in the grooves of the process strips, and cleaning the floating slurry in the grooves of the process strips.

[0020] By adopting the above technical solution, the groove of the process strip is cleaned before spraying the imitation stone paint, ensuring that there are no impurities in the groove, which is conducive to the uniform spraying and firm adhesion of the imitation stone paint, and improves the decorative effect and durability of the imitation stone paint layer.

[0021] Optionally, after the step of spraying the imitation stone paint layer, the step further includes: polishing and painting the process strips, polishing the inner wall of the process strips after the imitation stone paint is completely dry, and then brushing the grinding paint inside the polished process strips.

[0022] By adopting the above technical solution, the inner wall of the process strip is polished and painted with grinding paint after the imitation stone paint is completely dry, which further improves the appearance texture of the process strip and the coordination with the imitation stone paint layer.

[0023] Optionally, in the step of spraying the imitation stone paint layer, a penetrating primer, an intermediate paint and an imitation stone paint are sprayed sequentially on the finished surface of the leveling layer and the grooves of the process strips.

[0024] By adopting the above technical scheme, by spraying penetrating primer, intermediate paint and imitation stone paint in sequence, not only the adhesion and durability of the imitation stone paint layer are enhanced, but also the color of the imitation stone paint layer is made fuller and the texture is more realistic, achieving a decorative effect comparable to stone.

[0025] Optionally, the process strip has outer edges on both sides, and in the step of embedding the process strip, when the process strip is embedded in the dividing groove, the outer edges abut against the outer side of the insulation board.

[0026] By adopting the above technical solution, when the process strip is embedded, the outer edge abuts against the outer side of the insulation board, which not only helps to maintain the stability of the process strip, but also can limit the distance of the process strip embedded in the insulation board.

[0027] In summary, the present application includes at least one of the following beneficial effects: 1. By directly grooving and embedding process strips on the surface of the insulation board, the thickness of the leveling layer is greatly reduced, so it is not easy for the process strips and the leveling layer to crack due to excessive deadweight. At the same time, the use of bonding mortar combined with anchors to fix the insulation board, and the double anti-cracking layer composed of anti-cracking mortar and mesh cloth further enhances the connection strength and anti-cracking ability of the insulation layer, and improves the stability and durability of the insulation layer; 2. By setting an outer edge on the process strip, the distance at which the process strip is embedded in the insulation board can be indicated, thereby improving the neatness and stability of the process strip and preventing the process strip from tilting during installation.

[0030] The following is combined with Figure 1-7 This application is described in further detail.

[0031] Please refer to Figure 1 , Figure 1 A schematic flow chart of the steps of an embodiment of a stone-like paint deep groove construction process based on a thermal insulation layer provided by the present invention.

[0032] In a specific embodiment, the stone-like paint deep groove construction process based on the thermal insulation layer includes: S1, installing the insulation layer, installing multiple insulation boards 1 in sequence on the wall surface to form the insulation layer.

[0033] It should be noted that in this step, bonding mortar needs to be prepared first, and the amount prepared at one time must be used up within 60 minutes. The insulation board 1 is bonded to the surface of the wall base using the bonding mortar and the point frame method, and the bonding area of ​​the insulation board 1 is not less than 60%. After the insulation board 1 is bonded, adjacent insulation boards 1 abut against each other, and the outer surface of the insulation board 1 is flush and vertical.

[0034] S2, opening the concave dividing groove 2, and groove the surface of the insulation board 1 according to the designed grid size.

[0035] It should be noted that before grooving, first draw lines according to the grid size requirements and the width of the selected process strip 3 to guide the grooving. When the insulation board 1 is an organic material such as an extruded board, EPS polystyrene board, etc., a hot melt knife is used for grooving; when the insulation board 1 is a Class A material such as rock wool, glass wool board, etc., a plumber's grooving machine is used for grooving. It should be noted that the grooving width and depth should be greater than the selected process strip by 3mm-5mm.

[0036] S3, embed the process strip 3 with a groove into the dividing groove 2 on the surface of the insulation board 1, so that the groove of the process strip 3 faces the external environment of the insulation board 1, and the side of the process strip 3 away from the wall protrudes from the outer surface of the insulation board 1, and the side of the process strip 3 on the insulation board 1 on the same plane away from the wall is flush.

[0037] Among them, refer to Figure 2 The process bar 3 is a strip structure with a groove, and an outer edge 6 extends from the outer wall of the process bar 3. The outer edge 6 is sheet-shaped and fixed on the outer walls of both sides of the process bar 3, and a plurality of through holes (not shown in the figure) are opened on the outer edge 6.

[0038] It should be noted that before the process strip 3 is embedded in the dividing groove 2, a vertical and horizontal reference line is first hung on the insulation board 1 to control the process strip 3 to be on the same plane vertically. Then the dividing groove 2 of the insulation board 1 is filled with bonding mortar, and the side of the process strip 3 away from the groove opening is squeezed into the mortar of the dividing groove 2, and the outer edge 6 is against the outside of the insulation board 1. The side of the process strip 3 close to the groove opening is limited by the outer edge 6 and is also located outside the insulation board 1, and the outer edge 6 and the insulation board 1 are filled with bonding mortar. The structure of the process strip 3 embedded in the insulation board 1 is shown in FIG. Figure 3 .

[0039] In addition, the process strips 3 are linear, cross, T-shaped, and W-shaped. A linear process strip 3 is used in a dividing groove 2 extending in a straight line; a cross or T-shaped process strip 3 is used when a dividing groove 2 is connected horizontally and vertically; and a W-shaped process strip 3 is used in a dividing groove 2 at a positive corner of a wall.

[0040] S4: Install anchors 5, and fix the insulation board 1 to the wall with no less than 6 anchors / ㎡.

[0041] It should be noted that, refer to Figure 4 In this embodiment, the anchor 5 is an anchor bolt, and the anchor 5 is evenly distributed on the insulation board 1 in a plum blossom shape. At least two anchors 5 should be added to the joint position of the positive corner edge on each side of the door and window openings for reinforcement. The effective anchoring depth of the anchor bolt for the base wall is not less than 50mm, and the diameter of the anchor plate is not less than 60mm. When the anchor point encounters the process strip 3, the anchor point is offset, and part of the anchor bolt can pass through the outer edge 6 through the through hole, and the anchor plate is pressed against the outer side of the outer edge 6, thereby improving the connectivity between the outer edge 6, the insulation board 1 and the wall, so as to further improve the stability of the process strip 3 and the insulation board 1.

[0042] S5, scraping the leveling layer 4, using the leveling slurry to scrape the surface of the insulation board 1, using the side of the process strip 3 away from the wall as a reference point for the flatness of the leveling slurry, so that the finished surface of the leveling layer 4 is flush with the side of the process strip 3 away from the insulation board 1; S6, spraying a stone-like paint layer, spraying paint on the finished surface of the leveling layer 4 and the grooves of the process strips 3.

[0043] Further, in step S1, referring to Figure 4 , Figure 4 The blue line separates the separation groove 2. When the insulation boards 1 are pasted, the upper and lower layers are offset from each other, specifically, the junction of the two adjacent insulation boards 1 in the upper layer is opposite to the middle of the insulation board 1 in the lower layer. In step S2, the separation groove 2 opened on the surface of the insulation board 1 is offset from the edge line of the insulation board 1 itself to improve the stability of the joint between the two adjacent insulation boards 1 and improve the stability of the process strip 3 in the separation groove 2.

[0044] Further, in step S5, the leveling slurry includes anti-cracking mortar and putty material, and step S5 includes step S501 and step S502 which are performed successively. Step S501: Apply anti-cracking mortar on the surface of the insulation board 1, and apply it separately to each grid. At the same time, the anti-cracking mortar covers the outer edge 6 on the process strip 3, and the outer surface of the anti-cracking mortar does not exceed the side of the process strip 3 away from the insulation board 1. Step S502: After the anti-cracking mortar is dry, use a scraper to scrape the putty material to the outer surface of the anti-cracking mortar separately for each grid according to the grid effect. Take the side of the process strip 3 away from the insulation board 1 as the reference point, and scrape the outer surface of the putty material to be flush with the side of the process strip 3 away from the insulation board 1.

[0045] Furthermore, in step S501, the anti-cracking mortar is applied twice. The first time, 2mm-3mm of the bottom anti-cracking mortar is applied to the outside of the insulation board 1. When the bottom anti-cracking mortar is not dry, a single mesh cloth is pressed into the bottom anti-cracking mortar. The mesh cloth is within 20mm of the grid edge line, and the process strip 3 has 100mm mesh cloth on both sides to overlap the mesh cloth pressed into the bottom anti-cracking mortar. The overlap width is not less than 80mm to improve the crack resistance of the process strip. After the mesh cloth is pressed in, the second surface anti-cracking mortar is applied, and the surface anti-cracking mortar is scraped with a scraper so that the surface anti-cracking mortar completely covers the mesh cloth. It should be noted that the total thickness of the leveling layer 4 is controlled to be 3mm-5mm.

[0046] Furthermore, after step S5 and before step S6, step S51 is further included: cleaning the process strip 3, tearing off the protective film in the groove of the process strip 3, and cleaning the slurry in the groove of the process strip 3. In this step, the slurry in the groove that is difficult to fall off can be cleaned by grinding the inner wall of the groove with a grinding tool.

[0047] Further, the paint in step S6 includes a penetration primer, an intermediate paint, and a lychee-faced stone paint. Therefore, step S6 includes steps S601, S602, and S603 that are performed in sequence. Step S601: Use a pneumatic gun to spray the penetration primer. During spraying, the construction is carried out according to the principle of first up and then down, first left and then right, and first corners and then large surfaces. After the penetration primer is completely dry, the next process is carried out. Step S602: Use a pneumatic gun to spray the intermediate paint. The spraying principle is consistent with the spraying principle of the penetration primer, and the intermediate paint is sprayed at least twice. After the intermediate paint is completely dry, the next process is carried out. Step S603: Use a spray gun to spray the imitation stone paint. The distance between the nozzle and the wall is between 30cm-60cm. During spraying, the axis of the nozzle is perpendicular to the wall, and the spray gun moves at a uniform speed parallel to the wall.

[0048] Furthermore, after step S6, step S7 is also included: the process strip 3 is polished and painted. After the imitation stone paint is dried, the inner wall of the process strip 3 is polished, and then the grinding paint is applied inside the polished process strip 3.

[0049] Reference Figure 2 Furthermore, a decorative strip 7 extending together with the process strip 3 is fixed in the groove of the process strip 3. The decorative strip 7 has at least two and is respectively located at two opposite corners of the groove. The two sides of each decorative strip 7 that are far from each other are respectively connected to the two adjacent inner side walls of the process strip 3, so that the groove of the process strip 3 is stepped, so as to improve the three-dimensional effect of the process strip 3. The outer surface of the decorative strip 7 and the outer surface of the outer edge 6 are provided with a plurality of convex strips 8 protruding from the surface of the decorative strip 7. The convex strips 8 serve as anti-slip structures to prevent the paint on the surface of the decorative strip 7 from falling off easily. The convex strips 8 also enhance the connectivity between the outer edge 6 and the leveling layer 4, so that the leveling layer 4 is not easily displaced relative to the outer edge 6.

[0050] Reference Figure 5 Furthermore, the process bar 3 is equipped with a protective cover 9, which corresponds to the process bar 3, and the size of the protective cover 9 is adapted to the groove of the process bar 3, so as to be detachably connected to the groove of the process bar 3. The protective cover 9 is connected to the process bar 3 after step S3 and before step S5, so that the protective cover 9 is inserted into the groove to close the opening of the groove; and the protective cover 9 is removed from the process bar 3 after step S5. Therefore, when scraping the leveling layer 4, the scraped slurry is not easy to enter the groove of the process bar 3 through the blocking of the protective cover 9, so as to improve the neatness of the groove and reduce the need for cleaning and polishing the groove.

[0051] The protective cover 9 includes a cover plate 10, an abutting protrusion 11 and an interlocking assembly 12. The cover plate 10 is in the shape of a plate with a width and size corresponding to the width size of the groove. The abutting protrusion 11 is integrally formed on the peripheral side of the cover plate 10 and extends in a direction perpendicular to the plate surface of the cover plate 10, and the abutting protrusion 11 is used to abut against the decorative strip 7. Specifically, the cover plate 10 and the abutting protrusion 11 are inserted into the corresponding process strip 3, and the side of the abutting protrusion 11 away from the cover plate 10 abuts against the side of the decorative strip 7 close to the groove opening, so that the side of the cover plate 10 away from the decorative strip 7 is flush with the side wall of the process strip 3 at the groove opening, so that when the slurry at the outer edge 6 is scraped, the excess slurry can be scraped onto the surface of the cover plate 10, and then the slurry is scraped away from the surface of the cover plate 10, so as to improve the convenience and flatness of scraping the slurry at the outer edge 6.

[0052] Reference Figure 5 and Figure 6The interlocking assembly 12 includes a limiting column 121, a clamping plate 122, an elastic member 123, an adjustment seat 124, a rotating shaft 125, a handle 126, a mounting seat 127 and a locking bolt 128. Specifically, there are two limiting columns 121, which are fixed on the side of the cover plate 10 facing the abutting protrusion 11, and the two limiting columns 121 are symmetrical along the center line of the cover plate 10, and the length direction of the limiting columns 121 is perpendicular to the plate surface direction of the cover plate 10, and the two limiting columns 121 are distributed along the width direction of the cover plate 10.

[0053] There are two clamping plates 122, and the two clamping plates 122 slide on the two limiting columns 121 along the width direction of the cover plate 10 respectively. Specifically, a limiting groove 13 is opened on one side of the clamping plate 122, and the limiting column 121 is pressed into the limiting groove 13 at one end away from the cover plate 10 and slides in the limiting groove 13 along the width direction of the cover plate 10 to guide the moving direction of the clamping plate 122, and the part of the limiting column 121 pressed into the limiting groove 13 is in a dovetail shape with the thickness gradually increasing away from the cover plate 10, and the cross-section of the limiting groove 13 is in a dovetail shape adapted to the limiting column 121, thereby limiting the limiting column 121 from leaving the limiting groove 13.

[0054] The adjustment seat 124 is in the shape of an elliptical plate, and is located between the two clamping plates 122. The axis of the adjustment seat 124 is parallel to the length direction of the limiting column 121, and the ends of the two clamping plates 122 that are close to each other are respectively abutted against the opposite sides of the outer peripheral wall of the adjustment seat 124. The rotating shaft 125 is coaxially fixed to the adjustment seat 124, and the rotating shaft 125 is simultaneously rotatably connected to the cover plate 10, and the end of the rotating shaft 125 away from the adjustment seat 124 passes through the cover plate 10 and extends to face the side of the cover plate 10 that is away from the abutting protrusion 11.

[0055] By rotating the rotating shaft 125, the two ends of the long axis or the two ends of the short axis of the adjustment seat 124 can be opposite to the clamping plate 122. The elastic member 123 is a spring, and the elastic member 123 is connected between two adjacent clamping plates 122 to always give the two clamping plates 122 an elastic force to move toward each other, so that the two clamping plates 122 always abut against the outer peripheral wall of the adjustment seat 124 during the rotation of the adjustment seat 124.

[0056] Reference Figure 5 and Figure 7 The mounting seat 127 is U-shaped and fixed on the side of the cover plate 10 away from the abutting protrusion 11, so that the U-shaped opening of the mounting seat 127 faces the cover plate 10. The end of the rotating shaft 125 away from the adjusting seat 124 passes through the mounting seat 127, and the end of the rotating shaft 125 away from the adjusting seat 124 is fixed to the handle 126.

[0057] The handle 126 is in the shape of a square rod, and the locking bolt 128 is threadedly inserted through the handle 126 along the axis direction parallel to the rotation axis 125, and two insertion holes 14 are provided on the surface of the mounting seat 127 opposite to the locking bolt 128, and the insertion holes 14 are used for the locking bolt 128 to be inserted.

[0058] When the protective cover 9 is inserted into the groove until the contact protrusion 11 contacts the decorative strip 7, the handle 126 is rotated to drive the rotation and the adjustment seat 124, and the handle 126 is rotated until the locking bolt 128 is opposite to one of the insertion holes 14, and the locking bolt 128 is threadedly moved to be inserted into the insertion hole 14. At this time, the two ends of the long axis of the adjustment seat 124 contact the two clamping plates 122 respectively, so that the two clamping plates 122 are pushed away from each other by the adjustment seat 124 to contact the outer walls of the two decorative strips 7 away from the groove opening, and the end of the clamping plate 122 away from the adjustment seat 124 contacts the side of one of the convex strips 8 on the decorative strip 7 away from the groove opening, so that the protective cover 9 is restricted from being outwardly separated from the groove by the contact between the clamping plate 122 and the convex strip 8, so that the protective cover 9 is positioned relative to the process strip 3.

[0059] When the protective cover 9 needs to be removed after the slurry is scraped, the locking bolt 128 is first threadedly moved away from the mounting seat 127, and then the handle 126 is rotated 90 degrees to make the locking bolt 128 face the other insertion hole 14, and the locking bolt 128 is inserted into the other insertion hole 14. During the process, the handle 126 drives the adjustment seat 124 to rotate until the two ends of its short axis are respectively opposite to the two clamping plates 122, so that the two clamping plates 122 are pulled toward each other by the elastic member 123. At this time, the distance between the two ends of the two clamping plates 122 that are away from each other is less than the minimum distance between the decorative strips 7 on both sides of the groove, thereby pulling the protective cover 9 outward, that is, the protective cover 9 can be separated from the process strip 3.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
