Description

Technical Field

[0001] This invention relates to a prefabricated truss light steel frame-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, green, and energy-saving prefabricated structural systems is an important measure to promote 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 to promote the industrialization of urban low-density housing and county-level residential construction.

[0003] my country has a long coastline, and most coastal foundations and islands have limited bearing capacity and high requirements for ecological environmental protection. Therefore, most of the houses built are low-rise or multi-story buildings. The climate and environmental conditions in the coastal areas are relatively complex, and adverse factors such as salt spray erosion affect the mechanical performance and service life of the building structure.

[0004] 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.

[0005] 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

[0006] This invention proposes a prefabricated truss light steel frame-graphite polystyrene-reinforced foamed ceramic panel composite wall panel, mainly used as the outer wall panel for low-rise and multi-story light steel frame structures. It is assembled from inner leaf truss light steel frame combined with calcium silicate board (inner leaf panel), outer leaf truss light steel frame combined with reinforced foamed ceramic panel (outer leaf panel), and sandwich graphite polystyrene board. The inner and outer leaf truss light steel frame is welded from square steel tubes. The reinforced foamed ceramic panel is composed of a foamed ceramic panel with a decorative surface layer and a high-ductility mortar board with shear keys. The high-ductility mortar board consists of an inner wire mesh with a thickness of not less than 20mm, steel strips welded around the wire mesh, and a dovetail-interlocking frame around the perimeter. The prefabricated truss light steel frame-graphite polystyrene-reinforced foamed ceramic panel combination wall panel integrates structural, thermal insulation, decorative, and enclosure functions. It is lightweight, has good earthquake resistance, fire resistance, and corrosion resistance, and is easy to assemble and construct. It has three lines of earthquake protection: the reinforced foamed ceramic panel is the first line of protection, the support rods of the truss light steel frame are the second line of protection, and the truss light steel frame is the third line of protection.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A prefabricated truss-graphite polystyrene-reinforced foamed ceramic panel wall panel includes a light steel frame, reinforced foamed ceramic panels, calcium silicate boards, and graphite polystyrene boards. The light steel frame is divided into inner-leaf truss light steel frame and outer-leaf truss light steel frame. The inner-leaf truss light steel frame is connected to the calcium silicate boards via self-tapping screws to form a combined inner-leaf panel. The outer-leaf truss light steel frame is connected to the reinforced foamed ceramic panels via self-tapping screws to form a combined outer-leaf panel. The combined inner-leaf panel and the combined outer-leaf panel are connected by graphite polystyrene boards. The light steel frame is composed of light steel frame units arranged and combined; each light steel frame unit is composed of light steel frame beams and light steel frame columns welded vertically in sequence, as well as light steel frame diagonal support rods welded along the light steel frame beams and light steel frame columns.

[0008] Furthermore, the prefabricated truss-graphite polystyrene-reinforced foamed ceramic panel wall panel is characterized by the existence of shared light steel frame beams and light steel frame columns between adjacent light steel frame units.

[0009] 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.

[0010] 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 truss 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 composite connection structure.

[0011] Furthermore, the combined outer leaf plate, the combined inner leaf plate, and the graphite polystyrene board are connected as a whole by expanding foam.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] Furthermore, the method for constructing the prefabricated truss-graphite polystyrene-reinforced foamed ceramic panel wall panel includes the following: Step 1: Weld the light steel frame beams and columns perpendicular to each other, and weld the light steel frame diagonal support rods to the light steel frame beams and columns at an angle to form a light steel frame; it is divided into inner leaf truss light steel frame and outer leaf truss 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 outer leaf truss light steel frame to form a combined outer leaf panel; use self-tapping screws to connect the calcium silicate board to the inner leaf truss light steel frame to form a combined inner leaf panel. 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 surfaces of the light steel frame beams, light steel frame columns, light steel frame diagonal support rods 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 truss-graphite polystyrene-reinforced foamed ceramic panel wall panel.

[0017] Compared with the prior art, the present invention relates to a prefabricated truss light steel frame-graphite polystyrene-reinforced foamed ceramic panel composite wall panel and its construction method, which has the following advantages: (1) In the prefabricated truss light steel frame-graphite polystyrene-reinforced foamed ceramic panel composite wall panel of the present invention, the truss light steel frame diagonal support rods serve as the first line of earthquake resistance, the reinforced foamed ceramic panels serve as the second line of earthquake resistance, and the light steel frame serves as the third line of earthquake resistance. The prefabricated truss light steel frame-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.

[0018] (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.

[0019] (3) The truss light steel frame is welded in the factory. The reinforced foamed ceramic panel unit, which matches the size of the truss light steel frame, is small in size 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 light steel frame. It can be used as an exterior wall with a marble-like surface texture that integrates earthquake resistance, 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 misalignment between the assembled reinforced foamed ceramic panels under horizontal earthquake action. This improves the overall seismic toughness of the assembled truss light steel frame-graphite polystyrene-reinforced foamed ceramic panel composite wall, and significantly improves the ability of the composite wall panel to resist large earthquakes.

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] Prefabricated truss light steel frame - graphite polystyrene - reinforced foamed ceramic panel composite wall panel ( Figure 1 ), Truss light steel frame - reinforced foamed ceramic board combined outer leaf plate ( Figure 2 ), truss light steel frame grid - calcium silicate board inner leaf composite panel ( Figure 3 ), reinforced foamed ceramic board ( Figure 4 ), Truss light steel frame - reinforced foamed ceramic panel connection node ( Figure 5 ): Inner leaf truss light steel frame (1), outer leaf truss light steel frame (2), light steel frame beam (3), light steel frame column (4), light steel frame diagonal support rod (5), foamed ceramic board with decorative surface layer (6), reinforced connection type high ductility mortar board (7), wire mesh (8), steel strip (9), reinforced foamed ceramic board (10), shear key (11), frame with dovetail interlocking (12), calcium silicate board (13), graphite polystyrene board (14), self-tapping screw (15), foaming adhesive (16), structural adhesive (17).

[0027] The inner leaf truss light steel frame (1) and the outer leaf truss light steel frame (2) are formed by welding light steel frame beams (3), light steel frame columns (4), and light steel frame diagonal support rods (5); Reinforced foamed ceramic board (10): It is composed of a foamed ceramic board with decorative surface layer (6), a reinforced and connected high ductility mortar board (7), a wire mesh (8), and a steel strip (9). The reinforced foamed ceramic board (10) has a dot matrix distribution of shear keys (11), and the edge of the reinforced foamed ceramic board (10) is provided with a dovetail interlocking frame (12).

[0028] The reinforced foamed ceramic board (10) is connected to the outer leaf truss light steel frame (2) by self-tapping screws (15); the calcium silicate board (13) is connected to the inner leaf truss light steel frame (1) by self-tapping screws (15).

[0029] A graphite polystyrene board (14) is filled in the cavity between a reinforced foamed ceramic board (10) and a calcium silicate board (13); Foam (16) and structural adhesive (17) are used to fill the assembly seams of adjacent reinforced foamed ceramic plate (10) units.

[0030] The inner leaf truss light steel frame (1) and outer leaf truss light steel frame (2) are formed by welding light steel frame beams (3), light steel frame columns (4), and light steel frame diagonal support rods (5). The light steel frame beams (3) and light steel frame columns (4) are square steel tubes with a cross-sectional dimension of 80mm×40mm×4mm. The light steel frame diagonal support rods (5) are square steel tubes with a cross-sectional dimension of 40mm×40mm×4mm. The steel strength grade of the light steel frame members should preferably be Q335 grade steel.

[0031] The aforementioned foamed ceramic panel (6) with decorative surface layer is a weather-resistant, corrosion-resistant, fire-resistant, heat-insulating, and marble-textured panel formed by using silicon-based tailings as the main raw material and undergoing high-temperature melting, crystallization, and foaming processes. It integrates a porous insulation layer with a 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. A 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, and the porous foamed ceramic has a compressive strength of 3.5~7.5MPa. The inner surface of the foamed ceramic panel (6) is machined with dot-matrix distributed cylindrical grooves, each 40mm in diameter and depth. The frame is machined into a right-angled trapezoidal dovetail groove with a depth of 40mm and an angle of 45°.

[0032] The reinforced high-ductility mortar panel (7) is a fiber-reinforced composite material with cement, quartz sand, etc. as the matrix. The reinforced high-ductility mortar panel (7) is 20mm thick. The reinforced high-ductility mortar panel (7) and the foamed ceramic panel (6) with decorative surface layer are bonded together after the interface is coated with adhesive. During the casting process, a high-ductility mortar cylindrical shear key (11) filled with the cylindrical groove of the foamed ceramic panel and a dovetail interlocking frame (12) with high-ductility mortar poured into the right-angled trapezoidal dovetail groove of the foamed ceramic panel frame are formed. The high-ductility mortar has the mechanical characteristics of good deformation and high strength. Combined with the interface adhesive, shear key (11) and dovetail interlocking frame (12), which are all interface reinforcement measures, the deformation capacity of the foamed ceramic panel (6) with decorative surface layer is significantly improved, and its brittleness is reduced.

[0033] The wire mesh (8) is a galvanized orthogonal wire mesh arranged in the middle of the thickness of the reinforced high-ductility mortar board (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 enhance the deformation capacity of the reinforced high-ductility mortar board (7) and its shrinkage resistance under alternating cold / heat and dry / wet conditions, while also enhancing the stress performance of the reinforced foamed ceramic board (10).

[0034] 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 reinforced connection type high ductility mortar board (7) with dovetail interlocking frame (12). The steel strip (9) is 40mm wide and 3mm thick.

[0035] The reinforced foamed ceramic panel (10) 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 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 frame, 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 forms a strong edge constraint on the foamed ceramic panel, which significantly improves 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.

[0036] The shear key (11) is an interface reinforcement structure between the reinforced 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 is poured into the inner side of the foamed ceramic plate (6) with decorative surface layer, the high-ductility mortar is poured into the cylindrical groove and solidifies to form the shear key.

[0037] The dovetail-interlocking frame (12) is a reinforced and connected structure for the foamed ceramic board. The edge of the foamed ceramic board (6) with decorative surface layer is machined with a groove. The groove has a right-angled trapezoidal cross-section, a depth of 40mm, and an 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° 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 (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 and significantly improving its load-bearing capacity. The dovetail-interlocking frame (12) provides a reliable structure for the self-tapping screw assembly connection between the outer leaf truss light steel frame (2) and the reinforced foamed ceramic board (10).

[0038] The calcium silicate board (13) is a silicon-calcium board formed by molding and steam curing with fly ash, cement, and reinforcing fiber materials. The present invention uses a 20mm thick standard fire-resistant calcium silicate board. The calcium silicate board (13) has a strength of not less than 30MPa. It is fastened to the inner leaf truss light steel frame (1) with self-tapping screws (15).

[0039] The graphite polystyrene board (14) is a thermal insulation material filling the cavity between the reinforced foamed ceramic board (10) and the calcium silicate board (13). The graphite polystyrene board (14) is bonded to the light steel frame beam (3), light steel frame column (4), and light steel frame diagonal support rod (5) by foam adhesive around its perimeter. Its inner and outer surfaces are bonded to the reinforced foamed ceramic board (10) and the calcium silicate board (13) by 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.

[0040] The self-tapping screw (15) is a 6.3mm diameter self-tapping screw. It is used for fastening the inner leaf truss light steel frame (1) and calcium silicate board (13), and for fastening the outer leaf truss light steel frame (2) and reinforced foamed ceramic board (10).

[0041] 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 truss light steel frame-graphite polystyrene-reinforced foamed ceramic board composite wall panel.
