Description

Technical Field

[0001] The invention relates to the technical field of building engineering, in particular to a construction process of an integrated board with a composite stone facing. Background Art

[0002] With the rapid development of the construction industry, the performance requirements of exterior wall finishing materials are increasing day by day, requiring materials to have excellent decorative effects, and also to take into account functions such as lightweight, thermal insulation, waterproof and durable. Although traditional stone veneers have beautiful appearance and natural texture, they are heavy, difficult to construct, and difficult to meet the needs of modern buildings for energy conservation, environmental protection and multi-functional integration. Therefore, they are gradually developing towards composite stone veneer integrated panels. However, the construction process of existing composite stone veneers still has room for improvement.

[0003] The current composite stone veneer panels are directly pasted with adhesive mortar. Some panels are fixed by a single anchor or are not sealed, which can easily lead to loose bonding or water seepage in the joints. In addition, the existing technology lacks the integrated design of intelligent modules, and the functionality of the panels is relatively single, making it difficult to adapt to the needs of green buildings for intelligent temperature control, humidity control and photovoltaic power generation. At the same time, most traditional panels use non-recyclable core materials or high-carbon emission materials with limited service life, making it difficult to achieve environmental protection and sustainable development after construction. Therefore, there is an urgent need for a composite stone veneer integrated panel solution with efficient construction technology, comprehensive functions and environmental protection. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a construction process for an integrated board with a composite stone veneer, which solves the problems of low construction efficiency, insufficient functionality of the board and poor environmental performance in the prior art.

Intelligent function installation: embed photovoltaic modules, phase change temperature control modules or humidity control modules according to design requirements and connect to the building function system; S7, Quality acceptance: Check the flatness, verticality and joint sealing effect of the board to ensure the installation quality; S8.

[0007] Preferably, the number of the anchors is 4-6 per square meter, and they are installed at the edge and the middle of the plate.

[0008] Preferably, the width of the seam of the board material is 5-8 mm, and the seam is filled with waterproof sealant or a flexible sealing strip.

[0009] Preferably, the base layer treatment comprises the following steps: (1) Clean the surface of the base layer to remove dust, oil and loose particles; (2) Use mortar to repair uneven areas and ensure that the surface flatness error of the base does not exceed ±3 mm.

[0019] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Please refer to the attached Figure 1 The embodiment of the present invention provides a construction process of an integrated board with a composite stone veneer, which relates to an efficient installation process of an integrated board with a composite stone veneer, and improves the construction efficiency, decorative effect and multi-functional integration capability of the exterior wall decorative board by optimizing the construction steps, material configuration and intelligent module embedding. The implementation method is described in detail below in combination with specific steps.

[0021] 1. Material Preparation Before construction begins, prepare the required materials, including composite stone veneer integrated panels, bonding mortar, anchors and sealing materials.

[0022] Composite stone facing integrated board: This board consists of stone flakes (3-5 mm), a lightweight insulation core material (such as aerogel composite material or honeycomb aluminum core material) and a glass fiber reinforced composite board on the back.

[0023] Bonding mortar: Use high-performance bonding mortar to ensure that its bonding strength meets ≥0.8 MPa. Control the mortar consistency according to the product instructions. The recommended water-cement ratio is 0.25:1.

[0024] Anchors: Special anchors are made of stainless steel, which is highly corrosion-resistant and meets the needs of plate fixing.

[0025] Sealing materials: including waterproof sealant (silicone sealant or polyurethane sealant) and flexible sealing strips, used to fill the board seams.

[0026] 2. Basic processing Base treatment is the basic work to ensure the firm bonding of the board, including: Clean the base surface: Use a brush or high-pressure air equipment to clean the wall dust, oil stains and release agent residues.

[0027] Remove the loose particles on the surface of the base.

[0028] Flatness repair: If the wall surface is uneven with an error of more than ±3 mm, use cement mortar or leveling putty to repair it; After repair, the base layer should be fully maintained to ensure that its strength and bonding properties meet the construction requirements.

[0029] Apply interface agent: If the wall base is too smooth (such as concrete base), an interface agent needs to be applied to improve the bonding strength of the mortar.

[0030] 3. Line positioning Mark horizontal and vertical reference lines on the base surface according to the construction drawings to ensure the accurate installation position of the panels.

[0031] Use a laser level to calibrate the layout to avoid installation deviation due to cumulative errors.

[0032] The grid size of the wall marking should be consistent with the board specifications and take into account the board joint width (5-8 mm).

[0033] 4. Panel installation 4.1 Applying bonding mortar Mix 1 bag of dry mortar with 0.25 bags of water, and stir evenly. Let it stand for 5 minutes and then stir again before use.

[0034] Use a toothed spatula to evenly apply the bonding mortar on the back of the composite board. The thickness of the mortar should be controlled at 3-5 mm to avoid mortar overflow due to excessive thickness.

[0035] 4.2 Board pasting According to the positioning of the lines, fit the mortar-coated board to the surface of the base.

[0036] Use a rubber hammer to gently tap the surface of the board to ensure that the mortar is dense and there are no hollows.

[0037] 4.3 Anchor Fixing Install anchors at the edge and middle of the board. It is recommended to set 4-6 anchor points per square meter.

[0038] Use an electric hammer to drill holes at the junction of the plate and the base layer. The hole diameter should be slightly larger than the diameter of the anchor to ensure that the anchor is firmly embedded in the base layer.

[0039] 4.4 Plate seam treatment Leave a 5-8 mm expansion joint between adjacent panels to meet the needs of thermal expansion and contraction.

[0040] Fill the gap with waterproof sealant, and the surface of the sealant should be smooth and beautiful.

[0041] 5. Smart function installation 5.1 PV Panel Embedding If the panel is designed with integrated photovoltaic function, the flexible thin-film photovoltaic modules will be embedded into the back of the panel before installation; the outer layer of the photovoltaic modules will be covered with a transparent protective film to prevent scratches during construction.

[0042] The photovoltaic module cables are introduced into the indoor power system through the panel seams, connected to the inverter, and the photovoltaic system's power generation efficiency is tested.

[0043] 5.2 Phase change temperature control module embedding Microcapsule phase change material is pre-embedded in the thermal insulation core of the board, and the melting point of the material is set at 20-30°C, which is used to adjust the indoor temperature.

[0044] During construction, ensure that the temperature control module is fully integrated with the plate and do not damage the module shell.

[0045] 5.3 Embedding the Self-humidification Function The thermal insulation core material is compounded with the hygroscopic material, wherein the hygroscopic material is made of porous silicon-based material and treated with a super-hydrophobic coating.

[0046] After the humidity control module is constructed, a performance test is carried out to verify whether its moisture absorption / desorption rate meets the design requirements.

[0047] 6. Quality Inspection Installation quality check: Use a spirit level to check the flatness and verticality of the plate; the deviation should be less than ±2 mm.

[0048] Check the sealing of the board seams to ensure that there are no voids or bubbles in the sealant.

[0049] Functional module acceptance: Photovoltaic power generation efficiency test: Detect the power output of photovoltaic modules under standard lighting conditions.

[0050] Temperature control module test: Use temperature sensors to record the effect of environmental changes on the phase change material.

[0051] Humidity Control Module Test: Verify the response rate and capacity of the humidity control module under different ambient humidity.

[0052] 7. Post-maintenance Avoid strong impact or vibration within 7 days after the installation of the panels to ensure that the bonding mortar and anchors are cured.

[0053] Check the integrity of the sealant regularly and repair any aging or cracking that is found.

[0054] Perform maintenance on embedded PV panels and temperature control modules once a year, clean the surface of the PV panels and check the cable connections.

[0055] Technical principle Lightweight and high-strength design: Aerogel or honeycomb aluminum core materials are used to reduce the weight of the panels while ensuring that the compressive strength is not less than 100 MPa.

[0056] Intelligent function realization: Indoor temperature regulation is achieved by utilizing the heat absorption / exothermic characteristics of phase change materials; energy collection is achieved by photovoltaic modules; humidity control is achieved by combining hygroscopic materials with super-hydrophobic coatings.
