Description

Technical Field

[0001] This invention relates to the field of building structure engineering technology, and in particular to an integrated frame-decorative load-bearing wall panel, its structural system, and assembly method. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] With the advancement of industrialized construction, prefabricated steel structure buildings have been widely used due to their advantages such as fast construction speed, environmental protection and energy saving, and good seismic performance.

[0004] Currently, traditional steel structure modules often employ the method of welding square steel pipe diagonal braces in the middle of the steel frame to resist lateral forces, followed by building walls to enclose the braces. This construction method has the following shortcomings. Firstly, the rigid insertion of the diagonal braces directly disrupts spatial continuity, completely eliminating its adaptability to large open spaces. Furthermore, the braces themselves obstruct the view, preventing the installation of doors and windows in that area, severely compressing the building's functional layout flexibility and failing to meet the modern demand for transparency and flexibility. Secondly, the connection process between the diagonal braces and steel columns and beams is particularly cumbersome—it requires precise diagonal cutting of the braces and the creation of welding slits, followed by the addition of diagonal rigid connectors at corners as transition welding points. These multiple processes significantly lengthen the processing cycle and demand high skill levels from workers, making it susceptible to structural instability due to operational errors. Third, the connection process between the enclosure and the interior decoration is also inefficient: fixed-station processes such as masonry, plastering, grooving of electromechanical pipelines, and construction of the finishing layer need to be completed in sequence in the diagonal bracing area. Each step is closely linked but lacks the possibility of parallel operation. Delays in the preceding steps often lead to idle work, which reduces the overall installation efficiency and increases labor and time costs, which runs counter to the "highly efficient integration" concept pursued by modern prefabricated buildings. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings mentioned above by providing an integrated frame-decorative load-bearing wall panel, its structural system, and assembly method.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: a frame-decorative load-bearing integrated wall panel, comprising a wall panel frame formed by horizontal beams and columns connected end to end and enclosing it, wherein one or more columns are vertically arranged inside the wall panel frame, and the horizontal distance between each column is equal; A horizontal keel is installed within the wall panel frame. The end of the horizontal keel is provided with an angle bracket for connecting to the column on the adjacent side. The column and the horizontal keel are divided into several zones within the wall panel frame for filling the insulation layer. Wall panels are located in each of the aforementioned zones and cover the surface of the wall panel frame.

[0007] Furthermore, the transverse beams are located on the short side of the wall panel frame and are arranged vertically opposite each other, and the outer end faces of the two transverse beams are provided with multiple connection holes a.

[0008] Furthermore, the corner bracket is provided with tie rods on the end faces of the horizontal keel and the column, and bolts are provided on the tie rods to form a tie rod bolt group.

[0009] Furthermore, the corner brackets are symmetrically arranged on both sides of the intersection of the transverse keel and the column, and are connected into a whole by the through tie rod bolt group to form a three-dimensional grid-like force transmission path.

[0010] Furthermore, the transverse beams, the columns, and the transverse keels are all made of steel profiles.

[0011] A frame-decorative integrated wall panel structure system that works in conjunction with a steel frame to bear loads includes a steel frame and a frame-decorative integrated wall panel, wherein the steel frame comprises: The bottom frame is composed of a bottom beam and box corners. Multiple secondary beams are provided inside the bottom frame, and the multiple secondary beams are evenly distributed on the bottom frame. The top frame is composed of a top beam and box corners, and multiple purlins are evenly arranged inside the top frame; Steel columns, fixedly connected to the upper and lower distributed box corners, are used to distribute at the four corners of the steel frame and support the bottom frame and the top frame.

[0012] Furthermore, the opposing surfaces of the bottom beam and the top beam are provided with a plurality of connecting holes b, the spacing of each connecting hole b being matched with the spacing of each connecting hole a and inserted accordingly; The connecting holes a and b, located on the same axis, are fastened with tie rod bolts to ensure that the upper and lower ends of the integrated frame-decorative load-bearing wall panel are rigidly connected to the bottom beam and the top beam, and the integrated frame-decorative load-bearing wall panel is assembled onto the steel frame.

[0013] Furthermore, the bottom beam is a C-shaped steel, the secondary beam is an H-shaped steel, and the purlin is a C-shaped steel.

[0014] A method for assembling a structural system specifically includes the following steps: S1, the cutting, slitting of steel columns, box corners, bottom beams, secondary beams, top beams and purlins are completed in the factory; S2, weld 5 steel plates with a thickness of 16mm into box corners; S3, weld the four bottom beams to the four box corners respectively to form the bottom frame, and weld multiple secondary beams to the web of the bottom beams inside the bottom frame to form a grid structure; S4. Weld the four top beams to the four box corners respectively to form the top frame, and weld multiple purlins evenly along the length of the top beams inside the top frame; S5, hoist the bottom frame to the final assembly area, weld 4 steel columns to the 4 corners of the bottom frame, then hoist the top frame to the top of the steel columns, and weld the steel columns to the corners of the top frame to form a steel frame; S6, use columns and horizontal beams to weld together to form a wall panel frame, and add columns and horizontal keels inside the wall panel frame to form a grid. At the same time, use tie rod bolt groups to symmetrically fix angle brackets on both sides of the intersection of the horizontal keel and the column. S7, the insulation layer is filled in the partitions separated by columns and horizontal keels within the wall panel frame, and wall panels are installed on both sides of the wall panel frame to form a frame-decorative load-bearing integrated wall panel. S8. Assemble the integrated frame-decorative load-bearing wall panel in the steel frame, aligning the pre-drilled connection holes a on the transverse beams with the pre-drilled connection holes b on the bottom and top beams. At the same time, use tie rod bolts to fasten the integrated frame-decorative load-bearing wall panel to the steel frame, forming an integral load-bearing unit.

[0015] The beneficial effects of this invention are reflected in: The integrated frame-decorative load-bearing wall panel of this invention is rigidly connected to the bottom and top beams of the steel frame via connection holes a on its upper and lower horizontal beams and connection holes b on the bottom and top beams, using tie rod bolt assemblies. This allows the wall panel, as part of the structure, to bear vertical and horizontal loads, forming an integral whole with the steel frame to jointly resist external loads. Compared with traditional diagonal bracing steel modules, this significantly improves the overall rigidity and load-bearing capacity of the structural system, while ensuring spatial continuity and meeting the functional requirements of large open spaces in buildings. On-site bolt connections shorten the construction period, improve installation efficiency, and reduce labor and time costs. Furthermore, within the wall panel frame, columns, horizontal keels, and symmetrically arranged corner brackets and tie rod bolt assemblies form a three-dimensional grid-like force transmission path, ensuring that the load can be efficiently transferred from the wall panel to the internal skeleton and then to the main steel frame.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1 , Figure 2 The present invention discloses a frame-decorative integrated wall panel, including a wall panel frame, a horizontal keel 9, an insulation layer 10 and a wall decoration panel 11.

[0020] The wall panel frame is a frame structure formed by welding horizontal beams 7 and columns 8 one end to the other, which serves as the main load-bearing boundary of the integrated frame-decoration load-bearing wall panel.

[0021] To enhance the vertical load-bearing capacity of the integrated frame-decorative wall panel and to divide the interior space, one or more vertical columns 8 are installed within the wall panel frame. The horizontal distance between each column 8 is equal to ensure uniform stress distribution. Horizontal joists 9 are installed inside the wall panel frame via corner brackets 13 and connected to the columns 8 on the nearest side. Specifically, as shown... Figure 2As shown, angle brackets 13 are symmetrically installed on both sides of the intersection of the horizontal keel 9 and the column 8. Holes are drilled on both perpendicular surfaces of the angle brackets 13 to install tie rods 14, which penetrate the end faces of the horizontal keel 9 and the column 8 respectively, and are secured with bolts 15. The tie rods 14 and bolts 15 together form a tie rod bolt assembly. This symmetrical arrangement and through-connection method connects the horizontal keel 9 and the column 8 into a whole, forming a three-dimensional grid-like force transmission path, ensuring effective load transfer.

[0022] The wall panel frame is divided into several square sections by columns 8 and horizontal keels 9. These sections are filled with insulation layers 10. If materials such as rock wool and polyurethane are used, the thermal insulation requirements of the building can be met.

[0023] Furthermore, wall panels 11 (such as cement fiberboard, stone panels, metal panels, etc.) are located in each zone and cover the outer surface of the wall panel frame, forming the decorative surface layer of the building. Loads (such as wind loads and seismic forces) are first applied to the wall panels 11, then transferred to the grid framework composed of columns 8 and horizontal joists 9, and then converged through columns 8 and horizontal beams 7, and finally transferred to the main structure through connecting holes a12.

[0024] Preferably, the transverse beam 7, the column 8, and the transverse keel 9 are all steel profiles, such as square steel pipes, H-beams, or C-beams, which have the advantages of high strength and easy processing.

[0025] like Figure 3-5 As shown, this application also provides a structural system including the above-mentioned integrated frame-decorative load-bearing wall panel, including a steel frame and one or more integrated frame-decorative load-bearing wall panels assembled on the steel frame.

[0026] The steel frame includes: Bottom frame: It is welded from bottom beam 3 and box corners 2. The bottom beam 3 is connected end to end with the four box corners 2 to form a rectangular frame. Multiple secondary beams 4 are also provided inside the bottom frame. The secondary beams 4 are evenly distributed and welded to the web of the bottom beam 3 to form a grid structure, which is used as the bottom support.

[0027] Top frame: It is welded from the top beam 5 and the box corner 2. The structure is also connected end to end and welded to the box corner 2 at the four corners. Multiple purlins 6 are evenly arranged inside the top frame to support the upper carrier (roof panel or floor slab).

[0028] Steel column 1: There are four columns in total, which are vertically welded to the four box corners 2 of the bottom frame, and their tops are welded to the four box corners 2 of the top frame, thus connecting the bottom frame and the top frame into a whole space steel frame.

[0029] To achieve coordinated load-bearing between the wall panel and the steel frame, multiple connection holes b are provided on the opposing surfaces of the bottom beam 3 and the top beam 5 (i.e., the upper flange of the bottom beam 3 and the lower flange of the top beam 5), as well as transverse beams 7 located at the upper and lower ends of the wall panel frame. Multiple connection holes a12 are machined on the outer end faces of both the upper and lower transverse beams 7. The spacing of these connection holes a12 perfectly matches that of the connection holes b, serving as a key interface for connecting the integrated frame-decorative load-bearing wall panel to the steel frame.

[0030] Preferably, the bottom beam 3 and purlin 6 can be made of C-shaped steel, and the secondary beam 4 can be made of H-shaped steel, in order to obtain good load-bearing performance and facilitate connection.

[0031] In conjunction with the above structure, this application also provides a method for assembling the structural system, specifically including the following steps: S1, in the factory, completes the cutting, slitting work of all components (steel column 1, box corner 2, bottom beam 3, secondary beam 4, top beam 5, purlin 6, transverse beam 7, column 8, transverse keel 9, etc.) according to the design drawings.

[0032] S2, five 16mm thick steel plates are cut to the design dimensions and welded into a hexahedral box corner 2. Box corner 2 serves as a key node of the frame, possessing good strength and rigidity.

[0033] S3. Weld the four bottom beams 3 to the four box corners 2 respectively to form a rectangular bottom frame. Then, within the bottom frame, weld the two ends of multiple secondary beams 4 to the webs of the two opposite bottom beams 3 to form a grid structure. At this point, the prefabrication of the bottom frame unit is completed.

[0034] S4. Using a method similar to step three, weld the four top beams 5 to the four box corners 2 respectively to form the top frame. Then, within the top frame, weld multiple purlins 6 evenly along the length of the top beams 5, thus completing the prefabrication of the top frame unit.

[0035] S5. In the final assembly area, first hoist the bottom frame into place and fix it. Then, vertically weld four steel columns 1 to the four corners 2 of the bottom frame. Next, hoist the top frame to the top of the steel columns 1, and weld the upper ends of the steel columns 1 to the corresponding corners 2 of the top frame, thus forming a complete steel frame.

[0036] S6. In the factory area, columns 8 and horizontal beams 7 are welded together to form the outer frame of the wall panel. Inside the wall panel frame, internal columns 8 and horizontal keels 9 are installed according to design requirements to form a grid for dividing the area. At the same time, at each junction of the horizontal keel 9 and the column 8, corner brackets 13 and tie rod bolt groups are used for symmetrical fixing to ensure reliable connection.

[0037] S7. Insulation layer 10 is filled into the partition separated by column 8 and horizontal keel 9. Then, wall panel 11 is assembled on the outer surface of the wall panel frame by adhesive or mechanical connection, thereby completing the prefabrication of the frame-decorative load-bearing integrated wall panel.

[0038] S8. Transport / hoist the aforementioned integrated frame-decorative load-bearing wall panel to the corresponding position on the steel frame. Position the integrated frame-decorative load-bearing wall panel so that its upper and lower transverse beams 7 align with the upper flange of the bottom beam 3 and the lower flange of the top beam 5, respectively. Align the connecting holes a12 on the upper and lower transverse beams 7 with the connecting holes b on the bottom beam 3 and top beam 5 of the steel frame. Then, insert tie rod bolt sets (tie rods 14 and bolts 15) into each aligned hole and tighten them, thereby achieving a rigid connection between the integrated frame-decorative load-bearing wall panel and the steel frame. This connection method allows the integrated frame-decorative load-bearing wall panel to reliably transmit shear force, axial force, and bending moment, forming a unified load-bearing unit working together with the steel frame.

[0039] Finite element analysis was performed on steel modules using integrated frame-decorative load-bearing wall panels and steel modules with added diagonal bracing to evaluate the structural performance of the two structures under typical loads.

[0040] See Figure 6-9 This structural system is mainly used in low-rise and multi-story buildings. Based on existing actual working conditions, the total load to be borne by the upper part of the module is set at 1000kN, and the upper load to be shared by a single node is 250kN. In the analysis of applied lateral forces, for the traditional steel module with diagonal bracing, when the lateral force increases to 67.64kN, the structural constraint reaction force no longer increases, indicating that the stress limit has been reached. At this point, the corresponding lateral displacement of the structure is 141mm. For the steel module using the integrated frame-decorative load-bearing wall panel, when the lateral displacement reaches 149mm, the applied lateral force is 92.2kN, and the node reaches the stress limit. Comparing the ultimate lateral bearing capacity of the two structures, it can be seen that the lateral bearing capacity of the structure using the integrated frame-decorative load-bearing wall panel is increased by 36.31% compared to the diagonal bracing scheme. This indicates that under the same vertical load conditions, the integrated frame-decorative load-bearing wall panel not only meets the decorative function but also significantly enhances the overall lateral stiffness and load-bearing capacity of the module, exhibiting better comprehensive performance advantages.

[0041] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0042] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0043] Additionally, "multiple" refers to two or more.
