Description

Technical Field

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

[0002] Developing efficient, earthquake-resistant, and energy-saving prefabricated structural systems is a crucial measure for promoting the modernization and industrialization of the construction industry. Researching and developing high-performance prefabricated low-rise, multi-story earthquake-resistant, and energy-saving residential buildings is an urgent need for promoting the industrialization of low-density urban and county-level residential construction. my country has a coastline of 18,400 kilometers, with over 6,500 islands, including various islands. The coastal zone, consisting of the coastline and islands, accounts for approximately 13% of the country's total area. Most coastal foundations and islands have relatively low bearing capacity and high ecological protection requirements, thus the buildings constructed there are mostly low-rise and multi-story structures. The climate and environmental conditions in coastal areas are relatively complex, and adverse factors such as salt spray corrosion affect the mechanical properties and service life of building structures. Foamed ceramic materials, using silica-based tailings as the main raw material, undergo high-temperature melting, crystallization, and foaming processes to form a porous structure integrating an insulation layer and a decorative surface layer. This results in weather-resistant, corrosion-resistant, fire-resistant, and heat-insulating slabs with a marble-like surface texture, making them ideal for use in building exterior wall components, especially in coastal areas where they exhibit excellent corrosion resistance against salt spray corrosion.

[0003] Current technical bottlenecks: (1) In the common light steel frame-concrete sandwich polystyrene composite wall panel structure in engineering, the concrete is relatively heavy, and the thermal insulation performance of the concrete, especially its resistance to salt spray erosion, 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. Summary of the Invention

[0004] This invention proposes a prefabricated light steel frame-light steel lattice reinforced foamed ceramic panel composite wall panel structure. The prefabricated frame light steel lattice-graphite polystyrene-reinforced foamed ceramic panel composite wall panel is mainly used as the outer cladding wall panel for low-rise and multi-story light steel frame structures. It integrates structural, thermal insulation, decorative, and enclosure functions; it is lightweight, earthquake-resistant, fire-resistant, and corrosion-resistant; and is easy to assemble and construct. It has two lines of earthquake resistance: the reinforced foamed ceramic panel is the first line of defense, and the light steel lattice frame is the second line of defense.

[0005] This invention relates to a prefabricated frame-light steel grid-graphite polystyrene-reinforced foamed ceramic panel composite wall panel and its construction method, comprising a light steel grid, reinforced foamed ceramic panels, calcium silicate boards, and graphite polystyrene boards; the light steel grid is divided into an inner leaf frame light steel grid and an outer leaf frame light steel grid; the inner leaf frame light steel grid and the calcium silicate boards are connected by self-tapping screws to form a composite inner leaf panel. The outer leaf frame light steel grid and the reinforced foamed ceramic panels are connected by self-tapping screws to form a composite outer leaf panel. The composite inner leaf panel and the composite outer leaf panel are connected by graphite polystyrene boards.

[0006] Furthermore, the light steel frame is composed of light steel frame units arranged and combined. Each light steel frame unit is welded together from light steel frame beams and light steel frame columns, and adjacent light steel frame units share light steel frame beams and light steel frame columns.

[0007] Furthermore, the reinforced foamed ceramic board is composed of a foamed ceramic board with a decorative surface layer and a reinforced high-ductility mortar board; the foamed ceramic board with a decorative surface layer and the reinforced high-ductility mortar board are connected by shear keys and dovetail interlocking with dovetail interlocking frames.

[0008] Furthermore, the light steel frame is made of square steel tubes, and self-tapping screws pass through the square steel tubes of the outer leaf frame light steel frame. The frame light steel frame-reinforced foamed ceramic board with decorative surface layer and the reinforced high-ductility mortar board form a frame light steel frame-reinforced foamed ceramic board connection node. This connection node is a self-tapping screw connection structure between the light steel frame and the reinforced foamed ceramic board, which is a steel-high-ductility mortar combined connection structure.

[0009] Furthermore, the combined outer leaf plate, the combined inner leaf plate, and the graphite polystyrene board are connected as a whole by expanding foam.

[0010] Furthermore, the thickness of the reinforced connection type high ductility mortar plate is not less than 20mm, including an internal wire mesh, steel strips welded around the wire mesh, and a dovetail interlocking frame around the steel strips.

[0011] Furthermore, there is an assembly seam of not less than 20mm between each reinforced foamed ceramic panel. The inner area of ​​the assembly seam is filled with foam adhesive, and the outer area of ​​the assembly seam is sealed with structural adhesive.

[0012] Furthermore, the shear key is an interface reinforcement structure between the reinforced connection type high ductility mortar plate and the foamed ceramic plate with decorative surface layer; the foamed ceramic plate with decorative surface layer has pre-reserved dot-matrix distributed cylindrical grooves, and the high ductility mortar cylinders poured into the cylindrical grooves form shear keys.

[0013] Furthermore, the dovetail-interlocking frame is a frame reinforcement structure between the reinforced connection type high ductility mortar board and the foamed ceramic board with decorative surface layer, and also serves as a connection structure with the light steel frame; the cross-sectional shape of the dovetail-interlocking frame is a right-angled trapezoidal groove.

[0014] The prefabricated frame-type light steel grid-graphite polystyrene-reinforced foamed ceramic panel combination wall panel and its construction method are as follows: Step 1: Weld the light steel frame beams and light steel frame columns to form a light steel frame, which is divided into inner leaf frame light steel frame and outer leaf frame light steel frame; Step 2: Prepare the wire mesh with bent ends and weld steel strips around the wire mesh; Step 3: Using calcium silicate board, graphite polystyrene board, and foamed ceramic board with decorative surface layer, cylindrical grooves and trapezoidal dovetail grooves are machined on the inner side and frame of the foamed ceramic board with decorative surface layer, respectively. Step 4: Place the decorative foamed ceramic panel with its inner side facing up and the decorative side facing down on the mold table. Apply interface adhesive to the inner side of the decorative foamed ceramic panel. Lay and weld the bent wire mesh at the ends of the steel strips. The mold table is equipped with a dovetail interlocking frame structure corresponding to the dovetail groove. Pour high-ductility mortar and cure it to form a reinforced high-ductility mortar panel. The reinforced high-ductility mortar panel and the decorative foamed ceramic panel are assembled and connected through the dovetail groove to form a reinforced foamed ceramic panel. Step 5: Use self-tapping screws to connect the reinforced foamed ceramic board to the light steel frame of the outer leaf frame to form the combined outer leaf board; use self-tapping screws to connect the calcium silicate board to the light steel frame of the inner leaf frame to form the combined inner leaf board. Step 6: Transport the combined outer blades, combined inner blades, and graphite polystyrene boards to the construction site; Step 7: Apply dotted foam adhesive to the surface of the light steel frame beams, light steel frame columns and reinforced foamed ceramic panels of the combined outer leaf plate, and fill the cavity of the combined outer leaf plate with the outer surface of the graphite polystyrene board. Step 8: Apply dotted foam adhesive to the inner surface of the graphite polystyrene board, and fill the cavity of the combined inner blade plate with the inner surface of the graphite polystyrene board. Step 9: First fill the assembly joint between adjacent reinforced foamed ceramic panel units with expanding foam, then use structural adhesive to grout the joints to complete the construction of the prefabricated frame-graphite polystyrene-reinforced foamed ceramic panel wall panel.

[0015] Compared with the prior art, the present invention relates to a prefabricated frame light steel grid-graphite polystyrene-reinforced foamed ceramic panel composite wall panel and its construction method, which has the following advantages: (1) In the prefabricated frame light steel grid-graphite polystyrene-reinforced foamed ceramic panel composite wall panel of the present invention, the reinforced foamed ceramic panel serves as the first line of earthquake resistance, and the light steel grid frame serves as the second line of earthquake resistance. The prefabricated frame light steel grid-graphite polystyrene-reinforced foamed ceramic panel composite wall panel has the integrated functions of earthquake resistance, heat preservation, decoration, and enclosure, and has the technical characteristics of light weight, good earthquake and fire resistance, and convenient assembly and construction.

[0016] (2) Shear keys are set between the foamed ceramic board and the high-ductility mortar, which improves the shear resistance and synergistic deformation capacity of the interface between the foamed ceramic and the high-ductility mortar, and avoids the peeling of the mortar layer and cracking of the foamed ceramic due to the difference in shrinkage performance between the two. The combined frame formed by the high-ductility mortar with dovetail interlocking frame, the wire mesh and the steel strip enhances the interlocking bonding capacity between the foamed ceramic board and the high-ductility mortar surface layer, and provides strong edge restraint for the foamed ceramic board, which significantly improves the deformation capacity and load-bearing capacity of the foamed ceramic board. The dovetail interlocking frame with built-in steel strip is connected to the light steel frame with self-tapping screws, which is reliable in terms of force, significantly improves the assembly construction speed and reduces the construction cost.

[0017] (3) The light steel frame is welded in the factory. The reinforced foamed ceramic panel unit, which matches the size of the light steel frame, is small and easy to hoist. The foamed ceramic panel with decorative surface layer of this invention is combined with reinforced high-ductility mortar panels and then combined with the light steel frame. 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. The assembly gaps of adjacent reinforced foamed ceramic panels are sealed with viscoelastic foam and structural adhesive. This not only makes it waterproof, but also allows for small deformation expansion or contraction under temperature action. It also avoids direct compression and displacement between the assembled reinforced foamed ceramic panels under horizontal earthquake action. This improves the overall seismic toughness of the assembled frame light steel frame-graphite polystyrene-reinforced foamed ceramic panel composite wall panel and significantly improves the ability of the composite wall panel to resist large earthquakes.

[0025] Inner leaf frame light steel frame 1 and outer leaf frame light steel frame 2: formed by welding light steel frame beams 3 and light steel frame columns 4; Reinforced foamed ceramic board 9: It is composed of foamed ceramic board 5 with decorative surface layer, high ductility mortar 6, wire mesh 7, and steel strips 8. Shear keys 10 are distributed in a dot matrix pattern on the reinforced foamed ceramic board 9. The edge of the reinforced foamed ceramic board 9 is provided with a dovetail interlocking frame 11.

[0026] The reinforced foamed ceramic board 9 is connected to the outer leaf frame light steel frame 2 by self-tapping screws 14; the calcium silicate board 12 is connected to the inner leaf frame light steel frame 1 by self-tapping screws 14.

[0027] Graphite polystyrene board 13 fills the cavity between reinforced foamed ceramic board 9 and calcium silicate board 12; Foam 15 and structural adhesive 16 are used to fill the assembly seams of adjacent reinforced foamed ceramic panel units 9.

[0028] The inner leaf frame light steel grid 1 and the outer leaf frame light steel grid 2 are formed by welding light steel grid beams 3 and light steel grid columns 4. The light steel grid beams 3 and light steel grid columns 4 are square steel tubes with a cross-sectional dimension of 80mm × 40mm × 4mm. The steel strength grade of the light steel grid members should preferably be Q335 grade steel.

[0029] The aforementioned foamed ceramic panel 5 with decorative surface layer is a weather-resistant, corrosion-resistant, fire-resistant, heat-insulating panel with a marble-like surface texture, formed by using silica-based tailings as the main raw material and undergoing high-temperature melting, crystallization, and foaming processes to create a porous structure with an integrated insulation layer and decorative surface layer. The foamed ceramic panel consists of porous foamed ceramic and a high-density ceramic surface layer, with a total thickness of 100mm. The 5mm thick surface layer is made of high-density ceramic with a marble-like texture. The high-density ceramic has a compressive strength higher than 30MPa, while the porous foamed ceramic has a compressive strength of 3.5~7.5MPa. The inner surface of the foamed ceramic panel 5 has machined dot-matrix distributed cylindrical grooves, each 40mm in diameter and depth. The frame is machined into right-angled trapezoidal dovetail grooves, 40mm deep and at a 45° angle.

[0030] The aforementioned reinforced high-ductility mortar panel 6 is a fiber-reinforced composite material with cement, quartz sand, and other materials as the matrix. The reinforced high-ductility mortar panel 6 has a thickness of 20mm. It is cast together with the decorative foamed ceramic panel 5 after an interfacial adhesive is applied. During casting, high-ductility mortar cylindrical shear keys 10 filled with cylindrical grooves in the foamed ceramic panel and dovetail-interlocking frame 11 with high-ductility mortar poured into right-angled trapezoidal dovetail grooves in the foamed ceramic panel frame are formed. The high-ductility mortar possesses good deformation and high strength mechanical characteristics. Combined with the interfacial adhesive, shear keys 10, and dovetail-interlocking frame 11, these are all interfacial reinforcement measures to significantly improve the deformation capacity of the decorative foamed ceramic panel 5 and reduce its brittleness.

[0031] The aforementioned wire mesh 7 is a galvanized orthogonal wire mesh arranged in the middle of the thickness of the reinforced high-ductility mortar board 6. The wire mesh diameter is 1.5mm~2mm, and the spacing is 50mm. At the position of the dovetail-interlocking frame 11, the wire mesh 7 is bent 135° towards the foamed ceramic board side for anchoring, and the length of the wire mesh anchored within the dovetail-interlocking frame 11 is not less than 50mm. The wire mesh 7 can enhance the deformation capacity of the reinforced high-ductility mortar board 6 and its resistance to shrinkage under alternating cold / heat and dry / wet conditions, while also enhancing the load-bearing performance of the reinforced foamed ceramic board 9.

[0032] The steel strip 8 is a long, thin strip of steel plate welded around the wire mesh 7. The steel strip 8 is welded to the side of the wire mesh 7 near the foamed ceramic board, and is located in the reinforced connection type high ductility mortar board 6 with dovetail interlocking frame 11. The steel strip 8 is 40mm wide and 3mm thick.

[0033] The reinforced foamed ceramic panel 9 is composed of a foamed ceramic panel with a decorative surface layer and a reinforced high-ductility mortar panel. 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 perimeter frame with dovetail interlocking. Shear keys are set between the foamed ceramic panel and the high-ductility mortar, improving 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 bonding ability between the foamed ceramic panel and the high-ductility mortar surface layer, and provides strong edge constraint for the foamed ceramic panel, significantly improving its deformation capacity and load-bearing capacity. The reinforced foamed ceramic panel 9 has the technical advantages of integrating structure, enclosure, decoration, and insulation.

[0034] The shear key 10 is an interface reinforcement structure between the reinforced high-ductility mortar plate and the foamed ceramic plate. The foamed ceramic plate has pre-reserved cylindrical grooves with a diameter and depth of 40mm and a spacing of 300mm. After high-ductility mortar is poured into the inner side of the foamed ceramic plate 5 with decorative surface layer, the high-ductility mortar is poured into the cylindrical grooves and solidifies to form the shear key.

[0035] The dovetail-interlocking frame 11 serves as a reinforcement and connection structure for the foamed ceramic panel. The edge of the decorative foamed ceramic panel 5 has a machined groove with a right-angled trapezoidal cross-section, a depth of 40mm, and an angle of 45°. Steel strips 8 are welded to the wire mesh 7 within the area of ​​the dovetail-interlocking frame 11, and the wire mesh 7 is bent 135° inwards into the groove. After pouring high-ductility mortar, a trapezoidal cross-section steel-high-ductility mortar composite frame strip is formed. The dovetail-interlocking frame 11 enhances the bonding ability between the high-ductility concrete surface layer and the foamed ceramic panel, providing strong edge restraint for the foamed ceramic panel and significantly improving its load-bearing capacity. The dovetail-interlocking frame 11 also provides a reliable structure for the self-tapping screw assembly connection between the outer leaf frame light steel grid 2 and the reinforced foamed ceramic panel 9.

[0036] The calcium silicate board 12 is a silica-calcium board formed by molding and steam curing using fly ash, cement, and reinforcing fiber materials. This invention uses a 20mm thick standard fire-resistant calcium silicate board. The calcium silicate board 12 has a strength of not less than 30MPa and is fastened to the inner leaf frame light steel frame 1 using self-tapping screws 14.

[0037] The graphite polystyrene board 13 is an insulation material filling the cavity between the reinforced foamed ceramic board 9 and the calcium silicate board 12. The graphite polystyrene board 13 is bonded to the light steel frame beams 3 and light steel frame columns 4 around its perimeter using expanding foam. Its inner and outer surfaces are bonded to the reinforced foamed ceramic board 9 and the calcium silicate board 12 respectively using expanding foam. The thermal conductivity of the graphite polystyrene board 13 should preferably be lower than 0.047 W / (m·K), and its fire resistance rating should reach B1.

[0038] The self-tapping screw 14 is a 6.3mm diameter self-tapping screw. It is used for fastening the inner leaf frame light steel frame 1 and the calcium silicate board 12, as well as for fastening the outer leaf frame light steel frame 2 and the reinforced foamed ceramic board 9.

[0039] The foam 15 is a moisture-curing polyurethane elastic sealing foam material that fills the 80mm depth of the assembly seam between adjacent reinforced foamed ceramic plate 9 units, thereby blocking the cold bridge between the assembly seams of adjacent reinforced foamed ceramic plate 9 units and improving the thermal insulation performance of the structure. The structural adhesive 16 is a high-performance silicone structural adhesive that fills the surface of the assembly joint of adjacent reinforced foamed ceramic panel 9 units to a depth of 20mm. After the assembly joint is sealed with viscoelastic structural adhesive 16, it can be waterproof, allow small deformation expansion or contraction under temperature, and avoid direct compression and displacement between the assembled reinforced foamed ceramic panels under horizontal seismic action, thereby improving the overall seismic toughness of the assembled frame light steel grid-graphite polystyrene-reinforced foamed ceramic panel composite wall panel.

Place spacers between the steel wire mesh and the foamed ceramic board, and support templates around the decorative foamed ceramic board.

[0042] Step 4: Prepare high-ductility mortar and pour it into the inner side of the foamed ceramic board with decorative surface layer.

[0047] Step 9: First fill the assembly joint between adjacent reinforced foamed ceramic panel units with expanding foam, then use structural adhesive to grout the joints, thus completing the construction of the prefabricated frame light steel grid-graphite polystyrene-reinforced foamed ceramic panel composite wall panel.

Next, design and perform stress calculations on the connection node structure. Finally, based on the design scheme of the wall panels and their assembly connection nodes, draw detailed structural drawings and carry out fabrication, transportation, and on-site assembly construction.

Apply interface adhesive to the inside of the foamed ceramic panel with decorative surface layer layer. Lay and weld the end of the steel strip and bend the wire mesh.

Step 2: Prepare the wire mesh (7) with bent ends, and weld steel strips (8) around the wire mesh (7); Step 3: Using calcium silicate board (12), graphite polystyrene board (13), and foamed ceramic board with decorative surface layer (5), cylindrical grooves and trapezoidal dovetail grooves are machined on the inner side and the frame of the foamed ceramic board with decorative surface layer (5); Step 4: Place the decorative foamed ceramic board (5) with its inner side facing up and its decorative side facing down on the mold table. Apply interface adhesive to the inner side of the decorative foamed ceramic board (5). Lay and weld the end of the steel strip (8) with bent wire mesh (7). The mold table is equipped with a dovetail interlocking frame (11) structure corresponding to the dovetail groove. Pour high-ductility mortar and cure it to form a reinforced connection type high-ductility mortar board (6). The reinforced connection type high-ductility mortar board (6) and the decorative foamed ceramic board (5) are assembled and connected through the dovetail groove to form a reinforced foamed ceramic board (9). Step 5: Use self-tapping screws (14) to connect the reinforced foamed ceramic board (9) to the outer leaf frame light steel frame (2) to form a combined outer leaf board; use self-tapping screws (14) to connect the calcium silicate board (12) to the inner leaf frame light steel frame (1) to form a combined inner leaf board; Step 6: Transport the combined outer leaf plate, combined inner leaf plate, and graphite polystyrene board (13) to the construction site; Step 7: Apply dotted foam adhesive to the surface of the light steel frame beam (3), light steel frame column (4) and reinforced foamed ceramic board (9) of the combined outer leaf plate, and fill the cavity of the combined outer leaf plate with the outer surface of the graphite polystyrene board (13). Step 8: Apply dotted foam adhesive to the inner surface of the graphite polystyrene board (13) and fill the cavity of the combined inner leaf plate with the inner surface of the graphite polystyrene board (13). Step 9: First fill the assembly joint between adjacent reinforced foamed ceramic panel units with foam adhesive (15), then use structural adhesive (16) to grout the joint, and complete the construction of the prefabricated frame-graphite polystyrene-reinforced foamed ceramic panel wall panel.
