Description

Technical Field

[0001] The invention relates to the technical field of building decoration materials, and in particular to a simulated stone exterior wall decoration method. Background Art

[0002] With the continuous development of the construction industry, the requirements for building decoration materials are increasing day by day. The application of traditional dry hanging stone in high-rise and home decoration is limited due to its high cost, complex installation and heavy weight. Therefore, simulated stone is widely used in building exterior wall decoration as a substitute for traditional stone.

[0003] There are many problems with simulated stone in the prior art: poor simulation, poor texture and grain; complex construction, high requirements for construction technology; poor durability, easy to age after long-term exposure to harsh environments. In response to such problems, the present invention aims to create a new simulated stone exterior wall decoration method with high simulation, convenient construction, strong durability and environmental protection by updating the stone structure layer, so as to meet the diversified needs of modern buildings for beauty, economy and environmental protection.

[0007] Step 2: Construction of fiber reinforcement layer and environmentally friendly adhesive layer. Select high-quality reinforced fiber mesh cloth anti-cracking material, lay it on the base treatment layer, ensure there are no wrinkles and bubbles, and use environmentally friendly adhesive material to stick it to the base layer.

Use vibration and pressing technology to ensure that the base layer is dense and free of voids and reaches the required thickness and flatness.

[0046] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0047] Reference Figure 1 , a simulated stone exterior wall decoration method, comprising the following steps:

[0048] Step 1: Clean the base construction, remove dust, oil and other debris, check the flatness and strength of the base, ensure that the base is dry, select a suitable base treatment material, apply it evenly on the base, and ensure that the base treatment layer is dry and solidified.

[0049] Specifically, during the construction of the clean base, a level meter is used to accurately measure and check the flatness of the base, and the error is controlled within ±3mm. A rebound hammer is used to perform multi-point tests to test the strength to ensure that the strength of the base concrete reaches more than 90% of the design standard.

[0050] Preferably, after cleaning the base layer, the base layer is lightly polished to increase the adhesion of the base treatment material.

[0051] Furthermore, by testing and processing the base layer, the flatness and strength of the base layer are ensured, which has the effect of improving the adhesion and durability of the final decorative layer.

[0052] Step 2: Construction of fiber reinforcement layer and environmentally friendly adhesive layer. Select high-quality reinforced fiber mesh cloth anti-cracking material, lay it on the base treatment layer, ensure there are no wrinkles and bubbles, and use environmentally friendly adhesive material to stick it to the base layer.

[0053] Specifically, different specifications of reinforced fiber mesh cloth are selected according to the size and stress of the exterior wall. For large-area exterior walls, mesh cloth with larger mesh size (such as 10mm×10mm) and higher strength is selected to improve the overall crack resistance.

[0054] Furthermore, the use of high-quality reinforced fiber mesh cloth and environmentally friendly adhesive materials has the characteristics of providing additional crack resistance and reducing cracks caused by temperature changes or external forces.

[0055] Preferably, before laying the reinforced fiber mesh cloth, it is pre-soaked to better combine with the environmentally friendly adhesive material. The soaking time is controlled to be 5-10 minutes, and the diluent matching the adhesive material is used for soaking.

[0056] Furthermore, when pasting the reinforced fiber mesh cloth, the pasting method is adopted from the middle to both sides to avoid wrinkles. At the same time, a special scraper is used to evenly scrape the environmentally friendly adhesive material on the mesh cloth to ensure that the thickness of the adhesive material is uniform and controlled at 1-2mm.

[0057] Step three, construction of natural stone powder base layer, prepare natural stone powder, resin and other raw materials, mix them evenly according to the matching ratio, lay them on the reinforced fiber layer, and use automatic coating equipment to coat the mixed material on the fiber reinforcement layer and the environmentally friendly bonding layer to form a base layer. Use vibration, pressing and other processes to ensure that the base layer is dense and free of voids and reaches the required thickness and flatness.

[0058] Specifically, when preparing raw materials such as natural stone powder and resin, the natural stone powder is screened to remove large particles of impurities to ensure that the particle size of the stone powder is between 0.1-0.5mm. The resin is quality tested to check its viscosity, curing time and other indicators to ensure that it meets the construction requirements.

[0076] A connecting beam 20 is fixedly connected to the lower surface of the mobile mounting frame 16, and multiple connecting beams 20 are evenly distributed on the lower surface of the mobile mounting frame 16. A working beam 21 is fixedly connected to the upper surface of the mobile mounting frame 16, and the two working beams 21 are symmetrically distributed with the axis of the connecting beam 20 as the center.

[0078] A discharge cavity is formed on the surface of the pressurizing connection block 23 , and inner walls of the plurality of discharge cavities are fixedly connected to the inner wall of the mixing box 22 and the inner wall of the discharge pressurizing frame 24 , respectively, and the inner wall of the discharge cavity is circular.

[0079] An extrusion shaft 26 is sleeved on the inner wall of the discharge chamber, and one end of multiple extrusion shafts 26 penetrates and extends to one side surface of the mixing box 22.

[0088] Specifically, the automatic coating equipment works as follows during the construction process: first, a mixture of natural stone powder and resin is added to the mixture box 22, and then the PLC controller 3 is programmed according to the wall height to be coated and the amount of the mixture added to the mixture box 22.

[0089] After the PLC controller 3 is programmed, the PLC controller 3 automatically controls the winding reduction motor 10, the servo electric cylinder 19, the discharging reduction motor 30 and the vibration motor 34 to work. During coating, the servo electric cylinder 19 is first controlled by the PLC controller 3 to work, and the push rod in the servo electric cylinder 19 is extended or retracted to drive the mobile mounting seat to move linearly along the surface of the load-bearing support beam 15, drive the mixing box 22 and the coating frame 25 to move, and adjust the distance between the coating frame 25 and the wall.

The mixed material enters the pressurizing frame through the discharge cavity, and the internal volume of the pressurizing frame is gradually reduced to pressurize the mixed material. The pressurized mixed material enters the coating frame 25, and the coating frame 25 discharges the material and contacts the wall for coating. During the process, the PLC controller 3 synchronizes the winding reduction motor 10 to work, and the winding reduction motor 10 drives the cable winding wheel 9 to rotate. The cable winding wheel 9 synchronously winds up the two lifting cables 11, driving the lifting mounting seat 12 to move upward along the inner wall of the fixed gantry 4, so that the mixture extruded out of the coating frame 25 contacts the wall from bottom to top, and the wall surface is coated with the mixture. During the coating process, the PLC controller 3 controls the vibration motor 34 to work. After the mixture is coated on the wall, the mixture is maintained by the vibration pressure plate 32, and the vibration force generated by the vibration motor 34 is transmitted to the vibration pressure plate 32, and the vibration pressure plate 32 contacts the mixture to compact the mixture.

[0091] By setting up automatic coating equipment, when constructing the natural stone powder base layer, the mixture can be automatically coated on the fiber reinforcement layer and the environmentally friendly bonding layer. During the coating process, the mixed coating is compacted by the vibration motor 34, and the mixture is automatically smoothed by the vibration pressure plate 32, so as to achieve a better effect of simulated stone exterior wall decoration construction.

[0092] Step 4: Construction of color adjustment layer and texture simulation layer. Select appropriate inorganic pigments or color pastes for color adjustment according to design requirements, conduct appearance inspection to ensure uniform color, realistic texture, absence of defects such as bubbles and cracks, and perform performance tests. Apply pigments or color pastes evenly on the base layer, or use spray painting, embossing and other technologies to form a texture effect.

[0093] Specifically, in the construction of the color adjustment layer and the texture simulation layer, when selecting inorganic pigments or color pastes, in addition to considering the color, the light resistance, weather resistance and alkali resistance should also be considered.

[0094] Preferably, a small area sample test is carried out before construction, and the color change is observed after being exposed to the natural environment for a period of time.

[0095] Step 5. Construction of weather-resistant protective layer and waterproof and dustproof surface layer. Select suitable weather-resistant protective material and evenly apply the weather-resistant protective material on the color adjustment and texture simulation layer. Ensure that the protective layer is dry and solidified to play its protective role. Evenly apply the waterproof and dustproof material on the weather-resistant protective layer to form a smooth and impermeable surface layer. Wait for the surface layer to dry and solidify before inspecting and cleaning.

[0096] Specifically, during the construction of the weatherproof protective layer and the waterproof and dustproof surface layer, weatherproof protective materials should be selected according to local climatic conditions. If the local ultraviolet radiation is strong, weatherproof protective materials with high ultraviolet absorption capacity should be selected, such as acrylic materials containing special ultraviolet absorbers. When selecting waterproof and dustproof materials, consider their compatibility with weatherproof protective materials and conduct compatibility tests to ensure that no chemical reaction occurs between the two.

[0097] Furthermore, by setting up a weather-resistant protective layer and a waterproof and dustproof surface layer, and selecting materials with excellent weather resistance and waterproof performance, it is ensured that the exterior wall decoration can maintain a good appearance and performance under various climatic conditions. This has the characteristics of improving the overall durability of the building exterior wall and reducing maintenance costs.

[0098] By setting steps one to five, in the construction of simulated stone exterior wall decoration, not only the quality and durability of the decoration are improved, but also the construction efficiency and environmental friendliness are improved, while maintaining cost-effectiveness, thereby achieving the effect of meeting the needs of modern buildings for high-performance exterior wall decoration.
