Description

Technical Field

[0001] This utility model belongs to the field of modular building, and in particular relates to a modular wall assembly structure. Background Technology

[0002] With societal development and the accelerating pace of urban renewal, modular building systems that are detachable and flexibly adjustable have gained widespread application. Wall panel systems, as a crucial component of buildings, serve multiple functions including enclosure, room partitioning, sound insulation, and thermal insulation. However, in current technologies, the installation methods for wall panel systems are relatively fixed, and wall panel designs are often closely linked to the overall structure and layout. This makes it difficult to disassemble and reuse wall panels individually, hindering replacement and adjustment for later maintenance or changes in usage needs, thus limiting the flexible use of modular buildings. Furthermore, wall panels, doors, and windows are often assembled on-site, resulting in low construction efficiency and difficulty in ensuring quality control. Additionally, cold bridges exist at the connection points between wall panels and the structure, affecting energy efficiency and increasing maintenance costs. Utility Model Content

[0028] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0029] This utility model proposes a modular wall assembly structure for use in modular buildings. Figure 1 A plan view of a modular building is shown. The modular building is a single-span structure, including modular wall panels 10 and corner columns 20 set at the corners of the building. Several modular wall panels 10 are provided between adjacent corner columns 20. Adjacent modular wall panels 10 are connected to each other by male and female socket joints to form a whole wall. Modular wall panels 10 are connected to the two adjacent side facades of each corner column 20.

[0030] The modular wall assembly structure proposed in this utility model includes a corner connection unit and a top connection unit; wherein, the corner connection unit includes a modular wall panel 10 and a corner post 20, and the modular wall panel 10 is connected to the corner post 20 in pairs through a connecting component 60; the top connection unit includes a modular wall panel 10, a horizontal beam 40 and a top plate 50, and the modular wall panel 10 is connected to the horizontal beam 40 and the top plate 50 in pairs through a connecting component 60.

[0031] Through the above technical solution, the modular wall panel 10 is assembled and connected with the corner column 20, horizontal beam 40, and top plate 50, thus forming corner connection units and top connection units, ensuring that these structures are reliably connected in pairs. This not only improves the stability and safety of the overall structure, but also allows for the flexible removal of any modular wall panel 10 as needed without affecting the overall structure, facilitating wall panel maintenance and replacement. Furthermore, it allows for adjustments to the building structure according to actual needs, enabling combinations of different modular building structures and enhancing the flexibility and convenience of using modular buildings.

[0032] Furthermore, the modular wall assembly structure proposed in this utility model also includes a central connecting unit, which comprises modular wall panels 10 and central columns 30. The modular wall panels 10 are connected to the central columns 30 in pairs via connecting components 60. Specifically, Figure 2Another modular building structure is shown, which is a multi-span structure including modular wall panels 10, corner columns 20 located at the corners of the building, and central columns 30 spaced apart between the corner columns 20. Several modular wall panels 10 are provided between adjacent corner columns 20, between adjacent corner columns 20 and central columns 30, or between adjacent central columns 30. Each corner column 20 connects two modular wall panels 10, and each central column 30 connects three modular wall panels 10. This design allows for the flexible removal of any modular wall panel 10 as needed without affecting the overall structure, enabling adjustments to the internal structure and layout of the modular building. This facilitates diverse room layouts and functions, significantly improving the flexibility and convenience of using modular buildings.

[0033] like Figure 3 As shown in this application, the modular wall panel 10 includes a standard modular wall panel 11, and a window-mounted modular wall panel 12 and a door-mounted modular wall panel 13 manufactured based on the standard modular wall panel 11. Several modular wall panels 10 are assembled and connected to form an inner wall panel 90 and an outer wall panel 80. Through the above technical solution, the wall panel system in the modular building can be divided based on the standard modular wall panel 11 to form wall panels of standard specifications. Components such as doors and windows are combined with the wall panel system and assembled in the factory. After being transported to the construction site, the standard modular wall panel 11, the window-mounted modular wall panel 12, and the door-mounted modular wall panel 13 can be combined and expanded as needed to form walls with different functions. When the functional layout requirements of the building change, the above three types of wall panels can be arranged and assembled in different ways to form a new building layout.

[0034] The aforementioned connecting component 60 includes a first outer corner connector 62, a second outer corner connector 63, and an inner corner connector 61. In the corner connecting unit, the two side facades of the corner post 20 are respectively provided with the first outer corner connector 62 and the second outer corner connector 63. The ends of the two outer wall panels 80 are respectively embedded inside the first outer corner connector 62 and the second outer corner connector 63. The inner facades of the two modular wall panels 10 are connected as one unit through the inner corner connector 61.

[0035] Specifically, such as Figure 4As shown, the first outer corner connector 62 and the second outer corner connector 63 are both arranged along the height direction of the corner post 20, preferably located on the two adjacent sides of a corner of the corner post 20 near the interior, and the first outer corner connector 62 and the second outer corner connector 63 are aligned with the corner. One of the exterior wall panels 80 is connected to the corner post 20 through the first outer corner connector 62, and the other exterior wall panel 80 is connected to the corner post 20 through the second outer corner connector 63. The two exterior wall panels 80 are connected by an inner corner connector 61, realizing that each structural component in the corner connection unit is connected in pairs. This not only makes the connection more stable, but also allows any exterior wall panel 80 to be removed or replaced as needed without affecting other structural components, in order to meet usage requirements.

[0036] Preferably, in a specific embodiment, the inner corner connector 61 and the first outer corner connector 62 are L-shaped, and the second outer corner connector 63 is U-shaped. Both the first outer corner connector 62 and the second outer corner connector 63 are adapted to the ends of the modular wall panel 10. In use, the outer side of one facade of the first outer corner connector 62 is attached to one side facade of the corner post 20 and fixed to the corner post 20 by fasteners 70. Preferably, the fasteners 70 are screws and are evenly distributed along the height direction of the first outer corner connector 62. At the same time, the other facade of the first outer corner connector 62 is located on the side away from the corner post 20 and closer to the interior. One end of an exterior wall panel 80 is respectively attached to the inner side of the two facades of the first outer corner connector 62 and fixed by fasteners 70 passing through the other facade of the first outer corner connector 62. The first outer corner connector 62 is fixed; the opening of the second outer corner connector 63 faces the other outer wall panel 80, and the outer side of one of its facades is attached to the other side facade of the corner post 20 and fixed to the corner post 20 by fasteners 70; one end of the other outer wall panel 80 is attached to the inner side of the two facades of the second outer corner connector 63 respectively, and fixed to the second outer corner connector 63 by fasteners 70 passing through the other two facades of the second outer corner connector 63; the sides of the two outer wall panels 80 that are close to each other are attached to the outer side of the inner corner connector 61 respectively, and connected by fasteners 70; preferably, one facade of the inner corner connector 61 is attached to the outer side of the second outer corner connector 63, and the fasteners 70 pass through the inner corner connector 61 and the second outer corner connector 63 to fix them to the corresponding outer wall panels 80.

[0037] Furthermore, such as Figure 5As shown, in the central connecting unit, the two opposite ends of the central column 30 are connected to two exterior wall panels 80 via a first outer corner connector 62 and a second outer corner connector 63, respectively. The connection method is the same as that of the corner connecting unit and will not be described in detail here. Unlike the corner connecting unit, the side facade of the central column 30 near the interior is also provided with an exterior wall connector 64, with both ends of the exterior wall connector 64 connected to the two exterior wall panels 80. Preferably, the inner sides of the two exterior wall panels 80 are aligned with the side facade of the central column 30 near the interior. The exterior wall connector 64 is a flat plate component. The central section is connected to the column via fasteners 70. One end of the fastener is connected to an outer wall panel 80, and the other end is attached to the outside of a second outer corner connector 63, through which the fastener 70 passes to another outer wall panel 80. Inner corner connectors 61 are respectively located on both sides of the inner wall panel 90. One side of the inner corner connector 61 is attached to an outer wall connector 64 and connected to the central column 30 via fasteners 70. The other side of the inner corner connector 61 is attached to and connected to the inner wall panel 90. Through this technical solution, the two outer wall panels 80 in the central connection unit are connected to the central column 30 respectively and to each other. The inner wall panel 90 is connected to the two outer wall panels 80 and the central column 30 respectively via the inner corner connectors 61 and the outer wall connectors 64. By removing the inner corner connectors 61, the inner wall panel 90 can be removed to facilitate maintenance, replacement, and adjustments to the interior layout.

[0038] Furthermore, such as Figure 6 As shown, the top connection unit includes an exterior wall top unit, which includes an exterior wall panel 80, a horizontal beam 40, and a top plate 50. The connection assembly 60 also includes a Z-shaped connector 65. The top plate 50 is fixed to the horizontal beam 40 and the inner side of the exterior wall panel 80 through the Z-shaped connector 65. The exterior wall panel 80 is fixed to the lower part of the horizontal beam 40 through the first outer corner connector 62. Specifically, the Z-shaped connector 65 includes a vertical plate and two horizontal plates connected to both ends of the vertical plate and extending in opposite directions. The upper horizontal plate is attached to and connected to the horizontal beam 40 by fasteners 70. One end of the top plate 50 rests on the upper part of the lower horizontal plate and is fixed to the horizontal plate by fasteners 70. The horizontal plate of the first outer corner connector 62 is located at the lower part of the horizontal beam 40, and the vertical plate is located on the side away from the top plate 50, forming a space with the vertical plate of the Z-shaped connector 65 to accommodate the exterior wall panel 80. Preferably, the top of the exterior wall panel 80 is attached to the horizontal plate, the vertical plate of the first outer corner connector 62, and the vertical plate of the Z-shaped connector 65, and is fixed to the vertical plate of the first outer corner connector 62 and the vertical plate of the Z-shaped connector 65 by fasteners 70, respectively. Preferably, a waterproof component is also provided between the outer side of the exterior wall panel 80 and the horizontal beam 40 to improve the waterproof effect of the connection.

[0039] Furthermore, such as Figure 7As shown, the top connection unit also includes an inner wall top unit, which includes an inner wall panel 90, a horizontal beam 40, and a top plate 50. The connection assembly 60 also includes C-shaped connectors 66. The top plate 50 is fixed to the lower part of the horizontal beam 40 by the C-shaped connectors 66. The inner wall panel 90 is provided with inner corner connectors 61 on both sides. The inner corner connectors 61 are respectively attached to the C-shaped connectors 66 and connected to the top plate 50. Specifically, the openings of the C-shaped connectors 66 are arranged opposite to each other and are respectively fixed to the lower part of the horizontal beam 40. The ends of the two top plates 50 extend into the openings of the C-shaped connectors 66 and are fixed to the two top plates 50 by fasteners 70. The two inner corner connectors 61 are respectively connected to the C-shaped connectors 66 and form a space for installing the inner wall panel 90. The inner wall panel 90 is fixed by the fasteners 70. Preferably, the inner corner connectors 61 are connected to the top plate 50 by passing through the C-shaped connectors 66 with the fasteners 70.

[0040] It is understood that the top connecting unit, corner connecting unit and middle connecting unit in this application do not conflict with each other. The two ends of the same outer wall panel 80 or inner wall panel 90 constitute corner connecting units and / or middle connecting units, and the top end constitutes a top connecting unit.

[0041] Furthermore, thermal insulation pads are attached to the outer sides of the inner corner connector 61, the first outer corner connector 62, and the second outer corner connector 63, making the connection between the structural components in the top connection unit, the corner connection unit, and the middle connection unit tighter, achieving a good sealing effect, reducing thermal bridges at the connection points, and improving the energy-saving effect of the modular building.

[0042] The modular wall assembly structure proposed in this application includes the following steps:

[0043] S1. Standard modular wall panels 11 are manufactured in the factory, and door and window openings are made in the standard modular wall panels 11. The doors and windows are installed in the door and window openings respectively, forming a structure as shown in the figure. Figure 3 The wall panel 13 with a door and the wall panel 12 with a window are shown.

[0044] In this embodiment, the standard modular wall panel 11 is a 4m×7m steel structure sandwich wall panel. According to the requirements, two standard modular wall panels 11 are connected and expanded into a 2m×4m×7m wall panel, and three standard modular wall panels 11 are connected and expanded into a 3m×4m×7m wall panel, which serve as the interior wall panel 90 and the exterior wall panel 80 of the modular building.

[0045] Before installing the doors and windows onto the standard modular wall panel 11, the door and window openings should be edge-wrapped.

[0046] S2. Complete the assembly of the central column 30, corner column 20 and horizontal beam 40;

[0047] After the standard modular wall panel 11, the door-mounted modular wall panel 13, and the window-mounted modular wall panel 12 are manufactured, they are brought to the construction site together with other structural components of the modular building at a uniform speed for the installation of the main frame. The central column 30, corner column 20, and horizontal beam 40 should all be assembled before the modular wall panel 10 is installed.

[0048] S3. Install the connecting assembly 60 on the corner post 20 and the middle post 30;

[0049] Specifically, such as Figure 4 As shown, a first outer corner connector 62 and a second outer corner connector 63 are installed on the two sides of the corner of the corner column 20 near the interior side. Before installation, thermal insulation pads are pasted on the outside of the first outer corner connector 62 and the second outer corner connector 63, and then the two are fixed to the corner column 20 with self-tapping screws. Similarly, a first outer corner connector 62 and a second outer corner connector 63 are installed on the two opposite sides of the middle column 30.

[0050] S4. Install the connecting component 60 on the horizontal beam 40 corresponding to the outer wall panel 80;

[0051] According to the intended installation position of the exterior wall panel 80, the first outer corner connector 62 is installed at the lower part of the corresponding horizontal beam 40. Similarly, before installation, the thermal insulation pad is pasted on the outside of the first outer corner connector 62.

[0052] S5. Starting from one side of a corner post 20, install modular wall panels 10 sequentially in one direction until the initial fixing of the exterior wall panels 80 is completed.

[0053] In this application, the installation direction can be to install the modular wall panels 10 one by one along the clockwise or counterclockwise direction of the building exterior wall 80, and to install the standard modular wall panels 11, the door-equipped modular wall panels 13 and the window-equipped modular wall panels 12 in the preset positions according to the design.

[0054] Specifically, a corner post 20 is selected as the starting point for installation. The modular wall panel 10 is embedded inside the first outer corner connector 62 on the side of the selected installation direction, and the modular wall panel 10 is fixed to the first outer corner connector 62 using self-tapping screws. Then, the next modular wall panel 10 is installed. When installing to the middle post 30, the modular wall panel 10 is embedded in the second outer corner connector 63 on the corresponding side of the middle post 30, and another modular wall panel 10 is installed in the first outer corner connector 62 on the opposite side. Then, the outer wall connector 64 is fixed to the first outer corner connector 62 and the second outer corner connector 63 on both sides of the middle post 30 using self-tapping screws, and is inserted into the corresponding modular wall panel 10. The outer side of the modular wall panel 10 is also fixed by self-tapping screws passing through the first outer corner connector 62 and the second outer corner connector 63. Similarly, when installing to the corner post 20, the two modular wall panels 10 are respectively embedded in the first outer corner connector 62 and the second outer corner connector 63 and fixed by the outer self-tapping screws. Then, the inner corner connector 61 is installed at the angle formed by the two modular wall panels 10 and fixed by the self-tapping screws. The self-tapping screw on one of the outer walls 80 passes through the inner corner connector 61 and the second outer corner connector 63 at the same time.

[0055] S6. Fix the exterior wall panels 80 one by one to the horizontal beam 40;

[0056] Specifically, the upper end of the exterior wall panel 80 is inserted into the inner side of the first outer corner connector 62 at the lower part of the corresponding horizontal beam 40, and then fastened with self-tapping bolts.

[0057] S7. Install the top plate 50 corresponding to the external wall panel 80;

[0058] Specifically, Z-type connector 65 is installed on horizontal beam 40, and then one end of top plate 50 is inserted into the inside of Z-type connector 65. Z-type connector 65 and top plate 50 are fastened together with self-tapping bolts at the bottom. Z-type connector 65 is then fixed to the inside of exterior wall panel 80 with self-tapping bolts.

[0059] S8. Install the top plate 50 corresponding to the inner wall panel 90;

[0060] Specifically, C-type connectors 66 are installed on the horizontal beam 40, and then one end of each of the two top plates 50 is inserted into the corresponding C-type connectors 66.

[0061] S9. Install the inner wall panel 90 on the central column 30 and connect the inner wall panel 90 and the top plate 50.

[0062] Specifically, a modular wall panel 10 is temporarily placed at its intended installation location. Inner corner connectors 61 are installed on both sides of the end of the modular wall panel 10 closest to the central column 30, so that the inner corner connectors 61 are respectively attached to the outer wall connectors 64. Automatic bolts are installed on both sides of the inner corner connectors 61 to fix them to the modular wall panel 10 and the central column 30. Then, the modular wall panels 10 are connected one by one to form an inner wall panel 90. Next, the inner corner connectors 61 are placed on one side of the top of the inner wall panel 90 and fixed to the inner wall panel 90 using automatic bolts. Another automatic bolt is used to pass the inner corner connectors 61 through the C-shaped connectors 66 and fix them to the top plate 50. Then, the same method is used to install the inner corner connectors 61 on the other side of the top of the inner wall panel 90. The installation of all the inner wall panels 90 can be completed using the above method.

[0063] Through the above technical solution, this application forms a corner connection unit, a top connection unit, and a middle connection unit, realizing the assembly connection between modular wall panels, corner columns, middle columns, horizontal beams, and top panels. This ensures that the structural components of the corner connection unit, top connection unit, and middle connection unit are reliably connected in pairs, improving the stability and safety of the overall structure. Furthermore, without affecting the overall structure, any modular wall panel can be flexibly removed as needed, facilitating the maintenance and replacement of the wall panels. This allows for more convenient adjustments to the internal structure and layout of the modular building, enabling diversified room layouts and functions, and significantly enhancing the flexibility and convenience of using modular buildings.

[0064] By setting up standard modular wall panels, as well as window-mounted and door-mounted modular wall panels made based on the standard modular wall panels, the wall panel system can be divided based on the standard modular wall panels, forming wall panels of standard specifications. This facilitates assembly in the factory and transportation to the construction site for assembly, forming walls with different functions and improving construction efficiency. When the functional layout requirements of the building change, the above three types of wall panels can be arranged and combined in different ways to form a new building layout.

[0065] By setting up connecting components, a tight connection between different structural components is achieved. By attaching thermal insulation gaskets to the outer sides of the inner corner connector, the first outer corner connector, and the second outer corner connector, a good sealing effect is achieved, reducing thermal bridges at the connection points and improving the energy-saving effect of modular buildings.
