Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building prefabricated wall panels, and more specifically, to a steel corrugated wall panel and a prefabricated wall panel assembly. Background Art
[0002] Existing steel corrugated wall panels use 0.8-1.2mm galvanized steel sheets as the base, which are then sheared and bent to form panels. However, some decorative projects require extra-long and extra-wide steel corrugated wall panels, such as lobbies and cross-floor spaces. From a visual perspective, the design requires that the wall panels should not be processed in blocks, and their dimensions will far exceed the conventional panel sizes, reaching requirements of 2m in width and 6m in height. The conventional factory dimensions of steel corrugated walls are 100-1200mm in width and 100-2400mm in height, with an overall panel thickness of 12mm. Existing steel corrugated wall panels are mainly subjected to stress at the bending parts of the steel sheets, and their overall mechanical strength is not high. When the width and height exceed the conventional dimensions, the steel corrugated wall panels will be affected by gravity, temperature, and external forces during production, transportation, handling, and installation, resulting in bending, sagging, deformation, and twisting of the panels, which seriously affects the quality acceptance after installation.
[0003] The main mechanical properties of existing steel corrugated wall panels rely on the steel plate bending structure and composite steel corrugations. If you want to increase the mechanical properties of ultra-wide and ultra-high wall panels (such as compressive strength, bending resistance, elastic modulus, etc.), simply increasing the thickness of the steel plate and the thickness of the steel corrugations will lead to excessive increase in construction costs, poor cost-effectiveness, and installation difficulties caused by the overall weight being too heavy. Taking the steel corrugated wall panel 1200*4000mm as an example, the galvanized steel plate is 0.8mm thick (including corrugated plate), and the total weight is about 40KG; the steel plate thickness is 1.5mm (including corrugated plate), and the corresponding total weight is about 77KG.

[0029] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and specific embodiments, but are not intended to limit the present application.
[0030] The terms "first," "second," and similar terms used in this application do not denote any order, quantity, or importance, but are used only to distinguish. The terms "include," "comprise," and similar terms mean that the elements preceding the term include the elements listed after the term, and do not exclude the possibility of also including other elements.
[0031] like Figure 1 、 Figure 2 and Figure 3 As shown, according to an embodiment of the present application, a steel corrugated wall panel is provided, which includes a corrugated board 1, a connector 2, a bending plate 3 with a U-shaped cross-section and a first panel 4, the first panel 4 includes an outer display surface and an inner surface, the first panel surface of the bending plate 3 is attached to the side edge position of the inner surface of the first panel 4, and the bending plate 3 is extended along the edge of the first panel 4, the corrugated board 1 is attached to the inner surface of the first panel 4, and the corrugated board 1 is extended along the height direction of the first panel 4, the U-shaped opening of the bending plate 3 faces the corrugated board 1, the U-shaped inner cavity of the bending plate 3 is filled with concrete 5, and the connector 2 is connected to the second panel surface of the bending plate 3.
[0032] The outer display surface is generally the side that can be seen by the user after being decorated on the wall 15, and the inner surface is generally the side facing the wall 15 after being decorated on the wall 15. A bending plate 3 is set at the side edge of the panel surface of the first panel 4, and the first panel surface of the bending plate 3 is attached to the inner surface of the first panel 4. Concrete 5 is poured into the inner cavity of the bending plate 3, and the connector 2 is connected to the second panel surface of the bending plate 3. When installing the steel corrugated wall panel, it is only necessary to insert the connector 2 into the corresponding structure. The various structures of the present application cooperate with each other, and compared with conventional steel corrugated wall panels of the same thickness, the overall mechanical properties of the steel corrugated wall panel in terms of bending resistance, folding resistance and compression resistance can be improved, and the mechanical properties of the steel corrugated wall panel do not need to be improved by increasing the thickness of the steel corrugated wall panel.
[0033] Even when the panel width is extra-long, such as 2m, there's no need to increase the panel thickness (the thickness of a conventional 1.2m panel can be maintained) while still maintaining good mechanical properties. Therefore, compared to increasing the thickness of the steel plate to improve mechanical properties (e.g., a 2m width with a larger thickness leads to greater overall weight), this approach can reduce the weight of the overall steel corrugated wall panel, providing reliable mechanical support for the production, transportation, and installation of extra-wide and extra-long steel corrugated wall panels.
[0034] The first panel is generally a galvanized steel plate, but may also be a steel plate of other materials. The steel corrugated wall panel of the present application comprises a first panel and concrete 5, which can reduce costs and has a higher cost-performance ratio compared to the solution of thickening the panel as a whole.
[0035] In some embodiments, the outer display surface of the first panel 4 may be covered with a PVC film or the like to decorate the outer display surface.
[0036] like Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, the bending plate 3 includes a first side plate 6 and a second side plate 7 attached to the first panel 4. In the extension direction perpendicular to the bending plate 3, the width of the second side plate 7 is greater than the width of the first side plate 6. The larger width of the second side plate 7 facilitates the stability of the fixing of the bending plate 3 to the first panel 4.
[0037] In some embodiments, the bent plate 3 and the first panel 4 are bonded together using glue, such as PUR glue. In some embodiments, the corrugated board 1 and the first panel 4 can be bonded together using glue, such as PUR glue, and then hot-pressed. In some embodiments, the corrugated board 1 can be a corrugated board.
[0038] like Figure 1As shown, in some embodiments, a strip-shaped fixing body can be provided on the first panel 4 , and the fixing body is passed through the second side plate 7 of the bent plate 3 to strengthen the connection between the bent plate 3 and the first panel 4 .
[0039] In some embodiments, the width of the first panel 4 along the direction perpendicular to the height is 0.1-2 m. The width adaptability of the first panel 4 of the present application is good, and it can be used for ultra-wide panels of 2 m, and can also be used for panels with a width less than 1.2 m.
[0040] In some embodiments, the height of the first panel 4 is 100-2400 mm, and the overall thickness of the panel is 0.5-12 mm. Compared with conventional steel corrugated wall panels of the same thickness, the overall mechanical properties in terms of bending, folding and compression resistance are better.
[0041] In some embodiments, concrete 5 is made of ultra-high performance concrete (UHPC). UHPC is a high-strength, high-toughness, low-porosity, cement-based material. Its basic formulation principle is to achieve ultra-high strength and durability by increasing the fineness and activity of its constituents, eliminating the use of coarse aggregate, and minimizing internal pores and microcracks. UHPC offers exceptional performance, including high strength, fire resistance, explosion resistance, hail resistance, chemical corrosion resistance, high durability, aesthetics, ductility, and sustainability. Steel fibers play a key role in enhancing the toughness, deformation properties, and impact resistance of ultra-high-strength concrete.
[0042] The steel fiber in the UHPC can specifically be a copper-plated microfilament steel fiber, the copper-plated microfilament steel fiber has a length of 12-14 mm, a diameter of 0.18-0.23 mm, and a tensile strength of ≥3000 grade.
[0043] Ultra-high performance concrete (UHPC) can be classified as T / CECS 10107-2020. The corresponding expansion grades include UF1, UF2, and UF3. UF1 corresponds to an expansion S < 650mm, UF2 to an expansion 650 ≤ S < 750mm, and UF3 to an expansion S ≥ 750mm. The corresponding compressive strength grades include UC1, UC2, UC3, and UC4. UC1 corresponds to a compressive strength of 100MPa ≤ f < 120MPa, UC2 to 120MPa ≤ f < 150MPa, UC3 to 150MPa ≤ f < 180MPa, and UC3 to a compressive strength f ≥ 180MPa.
[0044] The performance of the ultra-high performance concrete (UHPC) model T / CECS 10107-2020 used in this application was tested, and the results are shown in the following table.
[0045]
[0046] Ultra-high performance concrete can be poured into the U-shaped cavity of the bent plate, vibrated and cured for about 28 days before being assembled onto the steel corrugated wall panel.
[0047] like Figure 4 As shown, in some embodiments, a U-shaped groove 8 is provided at the edge of the first panel 4 along the extending direction of the edge, and the U-shaped bent plate 3 fits into the U-shaped groove 8 of the first panel 4. The notch of the U-shaped groove 8 faces the corrugated board 1. The provision of the U-shaped groove 8 can better secure the bent plate 3 and improve the stability of the connection between the bent plate 3 and the first panel 4.
[0048] like Figure 5 、 Figure 7 、 Figure 8 and Figure 9 As shown, according to an embodiment of the present application, a prefabricated wall panel assembly is further provided. The prefabricated wall panel assembly includes the steel corrugated wall panel of any embodiment of the present application and a keel 9. The keel 9 is connected to the wall surface, and the extension direction of the keel 9 is consistent with the extension direction of the plug-in component 2 of the steel corrugated wall panel. The plug-in component 2 is connected to the keel 9 to fix the steel corrugated wall panel. The keel 9 is fixed to the wall surface, and the plug-in component 2 is connected to the keel 9, thereby fixing the steel corrugated wall panel to the wall surface.
[0049] like Figure 6 As shown, in some embodiments, the prefabricated wall panel assembly further includes a leveling member 16, which is fixedly connected to the wall surface, and the keel 9 is connected to the leveling member 16. For example, the leveling member 16 may include an angle piece and a fixing tube, wherein the angle piece connects the wall surface and the fixing tube. The fixing tube may be a square hollow tube.
[0050] like Figure 9 and Figure 10 As shown, in some embodiments, the keel 9 and the leveling member 16 can be connected by angle pieces and screws. The angle piece connects the keel 9 and the fixing tube. Then, one screw is inserted through the angle piece and the fixing tube, and another screw is inserted through the angle piece and the keel 9.
[0051] In some embodiments, the keel 9 is made of a black line keel or other materials.
[0052] like Figure 3 As shown, in some embodiments, the connector 2 is a plate with an L-shaped cross-section. The plate of the connector 2 extends along the second surface of the bent plate 3. The plate of the connector 2 includes a fixed plate 10 and a plug-in plate 11. The plug-in plate 11 extends into and is connected to the keel 9. The fixed plate 10 of the connector 2 can be attached to the second surface of the bent plate 3 to improve the stability of the connection between the connector 2 and the bent plate 3.
[0053] like Figure 5 and10 As shown, in some embodiments, the keel 9 is provided with a first socket and a locking portion 12. The end of the plug-in board 11 is provided with a plug-in portion. After the plug-in portion is inserted into the keel 9 through the first socket, the locking portion 12 locks the plug-in portion. For example, the plug-in portion of the plug-in board 11 has a curved structure. The locking portion 12 has a hook-shaped structure. After the plug-in portion is inserted into the keel 9, the hook-shaped structure of the locking portion 12 can block the curved plug-in portion, thereby securing the steel corrugated wallboard to the keel 9.
[0054] In some embodiments, the keel 9 may be a hollow tube with a first strip-shaped opening along its extension direction, so that the plug-in board 11 can extend into the keel 9 through the first opening. The keel 9 may have two first openings to facilitate connection of two adjacent steel corrugated wall panels to the same keel 9.
[0055] like Figure 1 、 Figure 3 and 10 As shown, in some embodiments, at least two blocks 13 are provided on the second plate surface of the bending plate 3. At least two blocks 13 are provided through the fixing plate 10, and the blocks 13 extend along the height direction of the first panel 4. A groove 14 is provided on the keel 9 at a position opposite to the plug-in component 2. When the keel 9 is connected to the plug-in component 2, the two blocks 13 at least partially extend into the groove 14 to limit the relative movement between the keel 9 and the plug-in component 2 along the height direction perpendicular to the first panel 4. The interlocking portion and the locking portion 12 are used to limit the movement of the steel corrugated wall panel perpendicular to the wall surface, and the cooperation of the blocks 13 and the groove 14 is used to limit the movement along the wall surface perpendicular to the height direction of the first panel 4, so as to improve the stability of the connection between the steel corrugated wall panel and the wall surface. The two blocks 13 can resist the two ends of the groove 14.
[0056] In some embodiments, the barrier 13 is a curved strip plate. The fixed end of the strip plate is fixedly connected to the bent plate 3, and the movable end of the strip plate is closer to the side edge of the first panel 4 relative to the fixed end. Generally, the movable end is oriented toward the adjacent first panel 4, which not only limits the displacement of the steel corrugated wall panels but also maintains a stable gap between adjacent steel corrugated wall panels. The strip plate is inserted through the fixed plate 10 to facilitate the securing of the bent plate 3 and the fixed plate 10.
[0057] like Figure 9 and 10 As shown, in some embodiments, connectors 2 and bent plates 3 with U-shaped cross sections can be provided on each side edge of the first panel 4 to secure the two ends of the steel corrugated wallboard. The two side edges of the first panel 4 can be the first side edge and the second side edge, respectively. The movable end of the strip plate retainer 13 at the first side edge faces toward the first panel 4 adjacent to the first side edge. The movable end of the strip plate retainer 13 at the second side edge faces toward the first panel 4 adjacent to the second side edge.
