Description

Technical Field

[0001] This invention relates to a prefabricated frame square timber grid-graphite polystyrene-reinforced foamed ceramic board composite wall panel and its construction method, belonging to the field of prefabricated building structure engineering technology. Background Technology

[0002] Bamboo grows quickly and is a rapidly renewable material. Most coastal areas and islands have limited load-bearing capacity and high ecological protection requirements, resulting in the construction of mostly low-rise or multi-story buildings. The climate and environmental conditions in coastal areas are relatively complex, and adverse factors such as salt spray erosion affect the mechanical properties and lifespan of building structures.

[0003] Foamed ceramic materials are made from silicon-based tailings as the main raw material. Through high-temperature melting, crystallization, foaming and other processes, a porous structure insulation layer and decorative surface layer are formed. The resulting material is weather-resistant, corrosion-resistant, fire-resistant, heat-insulating, and has a surface texture similar to marble. It is very suitable for use in building exterior wall components, especially in coastal areas where it has good corrosion resistance against salt spray erosion.

[0004] Current technical bottlenecks: (1) In the common timber frame-concrete sandwich polystyrene composite wall panel structure in engineering, the concrete is relatively heavy, and the thermal insulation performance, especially the salt spray erosion resistance, of the concrete is far inferior to that of foamed ceramic panels. (2) When foamed ceramic panels are used as enclosure decorative wall panels in engineering, they fail to play their seismic role because they are not reinforced by high-ductility mortar. (3) High-performance composite wall panels that combine bamboo plywood, wood, reinforced foamed ceramic panels, and sandwich insulation materials are in short supply. Summary of the Invention

[0016] Compared with the prior art, the present invention relates to a prefabricated frame square timber grid-graphite polystyrene-reinforced foamed ceramic panel composite wall panel and its construction method, which has the following advantages: (1) In the prefabricated frame square timber grid-graphite polystyrene-reinforced foamed ceramic board composite wall panel of the present invention, the reinforced foamed ceramic board serves as the first line of earthquake resistance, and the frame square timber grid serves as the second line of earthquake resistance, significantly improving the structural earthquake resistance performance.

[0017] (2) The high-ductility mortar surface layer of the steel wire mesh with shear keys and dovetail interlocking frame of the present invention can significantly improve the deformation capacity and load-bearing capacity of foamed ceramic materials. Combined with the frame square wood grid, it can be used as an exterior wall with an integrated surface texture similar to marble, which is earthquake-resistant, enclosure, heat preservation and decoration. It overcomes the disadvantages of dry-hanging marble exterior walls, such as heavy weight, easy hollowing, poor thermal performance, high cost, easy falling off, and serious consumption of natural resources. After the assembly gaps of adjacent reinforced foamed ceramic panels are sealed with viscoelastic structural adhesive, it can be waterproof, allow small deformation expansion or contraction under temperature action, and avoid direct compression and misalignment between the assembled reinforced foamed ceramic panels under horizontal earthquake action. This improves the overall earthquake toughness of the assembled square wood grid-graphite polystyrene-reinforced foamed ceramic panel combination wall, significantly reduces the damage under the action of a large earthquake, and achieves the performance-oriented design goal of rapid and low-cost repair.

[0018] (3) The frame timber grid is assembled by connecting steel plates, which is convenient for construction. The reinforced foamed ceramic panel unit, which matches the size of the timber grid, is small in size and easy to hoist. The reinforced foamed ceramic panel with dovetail interlocking frame is connected to the timber grid with self-tapping screws, which is convenient for assembly, reliable for connection and cost reduction. Compared with the traditional concrete ribbed composite shear wall, the self-weight of the timber grid is significantly reduced. The timber grid is covered by reinforced foamed ceramic panels, which effectively blocks the cold bridge effect and significantly improves the heat preservation and fire resistance.

[0033] The inner leaf frame square timber frame (1) and the outer leaf frame square timber frame (2) are formed by square timber frame beams (3) and square timber frame columns (4) connected by self-tapping screws (15) through node steel plates (5).

[0034] The square timber frame beams (3) and square timber frame columns (4) are rectangular cross-section wooden members. The square timber frame beams (3) and square timber frame columns (4) can be made of wood with high strength and toughness, which is not easily deformed and wear-resistant, such as fir and pine. Environmentally friendly preservatives such as alkaline quaternary ammonium copper are used to prevent the wood from rotting and becoming moldy, and fireproof and weather-resistant coatings are applied to the surface of the wood.

[0036] The aforementioned foamed ceramic board (6) with decorative surface layer is a weather-resistant, corrosion-resistant, fire-resistant, heat-insulating board with a marble-like surface texture, formed by using silicon-based tailings as the main raw material and undergoing high-temperature melting, crystallization, and foaming processes to create a porous structure insulation layer integrated with a decorative surface layer. The porous foamed ceramic part and the high-density ceramic surface layer of the foamed ceramic board have thicknesses of 95mm and 5mm respectively, with a total thickness of 100mm. The high-density ceramic has a compressive strength higher than 30MPa, and the porous foamed ceramic has a compressive strength of 3.5~7.5MPa. The inner surface of the foamed ceramic board (6) with decorative surface layer is machined with dot-matrix distributed cylindrical grooves, with a diameter and depth of 40mm. The frame is also machined with grooves, the cross-sectional shape of which is a right trapezoid with a depth of 40mm and an acute angle of 45°.

[0037] The high-ductility mortar (7) is a fiber-reinforced composite material with cement, quartz sand, etc. as the matrix. The high-ductility mortar (7) is 20mm thick and is bonded to the interface adhesive on the inner side of the foamed ceramic board (6) with decorative surface layer. The high-ductility mortar (7) poured into the cylindrical groove and the right-angled trapezoidal groove of the frame of the foamed ceramic board respectively forms shear keys (11) and dovetail-interlocking frame (12). The high-ductility mortar has the mechanical characteristics of good deformation and high strength. Combined with the interface reinforcement measures of interface adhesive, shear keys (11) and dovetail-interlocking frame (12), the deformation capacity of the foamed ceramic board (6) with decorative surface layer can be significantly improved, and its brittle fracture characteristics can be improved.

[0038] The wire mesh (8) is a galvanized orthogonal wire mesh arranged in the middle of the thickness of the high-ductility mortar (7). The wire mesh diameter is 1.5mm~2mm and the spacing is 50mm. The wire mesh (8) is bent 135° towards the foamed ceramic board at the position of the dovetail interlocking frame (12) for anchoring. The length of the wire mesh anchored in the dovetail interlocking frame (12) is not less than 50mm. The wire mesh (8) can improve the deformation capacity of the high-ductility mortar (7) and reduce the shrinkage of the high-ductility mortar (7) under alternating cold / heat and dry / wet conditions, thereby enhancing the stress performance of the reinforced foamed ceramic board (10).

[0039] The steel strip (9) is a long strip of thin steel plate welded around the wire mesh (8). The steel strip (9) is welded to the side of the wire mesh (8) near the foamed ceramic board and is located in the high ductility mortar (7) with dovetail interlocking frame (12). The steel strip (9) is 40 mm wide and 3 mm thick.

The reinforced high-ductility mortar panel consists of an internal wire mesh panel with a thickness of not less than 20mm, steel strips welded around the wire mesh, and a frame with dovetail interlocking around the perimeter. Shear keys are set between the foamed ceramic panel and the high-ductility mortar, which improves the shear resistance and coordinated deformation capacity of the interface between the foamed ceramic and the high-ductility mortar. The constraint frame formed by the high-ductility mortar with dovetail interlocking, the wire mesh, and the steel strips enhances the interlocking bonding capacity between the foamed ceramic panel and the high-ductility mortar surface layer, and provides strong edge constraint for the foamed ceramic panel, significantly improving the deformation capacity and load-bearing capacity of the foamed ceramic panel. The reinforced foamed ceramic panel (10) has the technical advantages of integrating structure, enclosure, decoration, and insulation.

[0041] The shear key (11) is an interface reinforcement structure between the reinforced connection type high ductility mortar plate and the foamed ceramic plate. The foamed ceramic plate has a dot matrix of cylindrical grooves with a diameter and depth of 40 mm and a spacing of 300 mm. After the high ductility mortar (7) is poured into the inner side of the foamed ceramic plate (6) with decorative surface layer, the high ductility mortar (7) enters the cylindrical groove. After the high ductility mortar (7) solidifies, it forms a shear key.

The edge of the foamed ceramic board (6) with decorative surface layer is grooved, with a right-angled trapezoidal cross-section, a depth of 40mm, and an acute angle of 45°. Steel strips (9) are welded onto the wire mesh (8) in the area of ​​the dovetail-interlocking frame (12), and the wire mesh (8) is bent 135° inwards into the groove. After pouring high-ductility mortar (7), a trapezoidal cross-section steel-high-ductility mortar composite frame strip is formed. The dovetail interlocking frame (12) enhances the interlocking bonding ability between the high ductility concrete surface layer and the foamed ceramic board, providing stronger edge constraints for the foamed ceramic board, which can significantly improve the stress performance of the foamed ceramic board and reduce the risk of damage to the reinforced foamed ceramic board (10) during transportation and installation; the dovetail interlocking frame (12) enables efficient self-tapping screw assembly connection between the frame square timber grid (1) and the reinforced foamed ceramic board (10).

[0043] The bamboo plywood (13) is a board made of bamboo as the main structural and filling material and formed under high pressure. A standard 20mm thick bamboo plywood is used and self-tapping screws (15) are used to fasten it to the inner leaf frame square wood frame (1).

[0044] The graphite polystyrene board (14) is a thermal insulation material that fills the cavity of the reinforced foamed ceramic board (10) and the bamboo plywood (13). The graphite polystyrene board (14) is bonded to the square timber frame beams (3) and square timber frame columns (4) with foam adhesive around its perimeter. Its inner and outer surfaces are bonded to the reinforced foamed ceramic board (10) and the bamboo plywood (13) with foam adhesive, respectively. The thermal conductivity of the graphite polystyrene board (14) should be lower than 0.047 W / (m·K), and its fire resistance rating should reach B1 level.

[0045] The self-tapping screw (15) is a 6.3mm diameter self-tapping screw. It is used for fastening the inner leaf frame square wood frame (1) and bamboo plywood (13), and for fastening the outer leaf frame square wood frame (2) and reinforced foamed ceramic board (10).

[0046] The foaming adhesive (16) is a moisture-curing polyurethane elastic sealing foam material. It fills the 80mm depth of the assembly seam of adjacent reinforced foamed ceramic plate (10) units, which can block the cold bridge of the assembly seam of adjacent reinforced foamed ceramic plate (10) units and improve the thermal insulation performance of the structure. The structural adhesive (17) is a high-performance silicone structural adhesive that fills the surface of the assembly joint of adjacent reinforced foamed ceramic board (10) units to a depth of 20mm. After the assembly joint is sealed with viscoelastic structural adhesive (17), it can be waterproof, allow small deformation expansion or contraction under temperature action, and avoid direct compression and displacement between the assembled reinforced foamed ceramic boards under horizontal earthquake action, thereby improving the overall seismic toughness of the assembled frame square wood grid-graphite polystyrene-reinforced foamed ceramic board composite wall panel.
