Description
Technical Field
[0001] This utility model relates to the field of modular building technology, and in particular to a lightweight partition wall for modular buildings that is easy to dismantle and modify. Background Technology
[0002] In recent years, modular construction has developed rapidly. Modular construction is a construction method that breaks down a building into independent modules (such as rooms, units, or functional components), prefabricates them in a factory, and then transports them to the site for assembly. The final result is a building entity that meets safety, reliability, and related functional requirements. Compared with traditional construction methods, modular integrated construction has advantages such as high construction efficiency, resource conservation, environmental friendliness, and civilized construction. Lightweight partition walls are a core component in concrete modular construction that enables flexible space division, taking into account characteristics such as lightweight, strength, sound insulation, and rapid installation.
[0003] Currently, lightweight partition walls in conventional modular concrete buildings typically have ring beams at their top and bottom, with a height of 250mm. The purpose of these ring beams is to ensure good integrity between the concrete portion of the lightweight partition wall and the autoclaved lightweight concrete (ALC) partition wall panel. However, some projects require subsequent demolition and alteration; however, demolishing the lightweight partition walls of the concrete modules in these projects is difficult. Because the ring beam is cast integrally with the concrete module, demolition requires breaking the concrete, which can easily damage the reinforcing steel in the main structure and is difficult to remove. Furthermore, ALC panels have weak impact resistance, resulting in low overall rigidity of the lightweight partition wall after installation, making it prone to localized damage during demolding, transportation, and hoisting.

[0038] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0039] Example:
[0040] like Figure 1As shown, this embodiment provides a lightweight partition wall for modular buildings that is easy to dismantle and modify. The lightweight partition wall includes, from top to bottom, a horizontally arranged upper ring beam 2, a lower ring beam 5, multiple ALC (Alternating Current Carbide) slabs 3 and multiple structural columns 4 vertically arranged between the upper ring beam 2 and the lower ring beam 5, as well as multiple first connecting components 6 and multiple second connecting components 7. The ALC slabs 3 and structural columns 4 are arranged alternately in the transverse direction. The ALC slab 3 is formed by connecting multiple ALC slabs 31 transversely. The multiple first connecting components 6 are used to longitudinally connect the ALC slab 3 to the upper ring beam 2 and the lower ring beam 5. The multiple second connecting components 7 are used to transversely connect the ALC slab 3 to two adjacent structural columns 4. The upper ring beam 2, the lower ring beam 5, and the structural columns 4 are formed by casting and curing based on the ALC slab 3. By extensively arranging ALC panels 31 and compressing the height of the upper ring beam 2 and lower ring beam 5, most of the concrete walls in the modular building are replaced with easily removable ALC panels 31, meeting different demolition and modification needs in actual projects and significantly expanding the application scenarios of the module. The lightweight partition wall of this application has wide applications, significantly reduced weight, and is easy to install. Furthermore, the removal of the ALC panels 31 in the lightweight partition wall is also relatively convenient, allowing for flexible adaptation to the demolition and modification needs of different projects. Multiple first connecting components 6 can longitudinally connect the ALC panels 31 to the upper ring beam 2 and lower ring beam 5, while multiple second connecting components 7 can laterally connect adjacent ALC panels 31 to the structural columns 4. The lightweight partition wall utilizes a reinforced connection technology between the ALC panels 31 and concrete, enhancing the connection between the ALC panels 31 and the upper ring beam 2, and between the structural columns 4 and the lower ring beam 5, thereby increasing the rigidity of the lightweight partition wall. This ensures that the deformation of the lightweight partition wall under various transportation conditions after production, such as horizontal and vertical lifting, meets quality control standards, and overall improves the production precision of the concrete module products.
[0041] Preferably, such as Figure 1 As shown, the lightweight partition wall for modular buildings, which is easy to dismantle and modify, also includes a beam formwork 1, which is horizontally positioned at the top of the upper ring beam 2. Of course, the top of the upper ring beam 2 can also be other structures.
[0042] It should be noted that in the process of making lightweight partition walls for modular buildings that are easy to dismantle and modify, the ALC whole panel 3 is placed in the casting mold. After the ALC whole panel 3 is connected with the first connecting component 6 and the second connecting component 7, concrete is poured to form the beam mold 1, the upper ring beam 2, the lower ring beam 5 and the structural column 4 to form the lightweight partition wall.
[0043] In a preferred embodiment of this utility model, the height of the upper ring beam 2 and the lower ring beam 5 is less than 250mm, and an ALC plate 3 is formed by connecting at least three ALC plates 31 horizontally in sequence.
[0044] It should be noted that the specifications of the upper ring beam 2, the lower ring beam 5, and the ALC slab 3 are determined based on the on-site construction and construction drawings, and the specific specifications are not limited here.
[0045] In order to vertically connect each ALC plate 3, the upper ring beam 2, and the lower ring beam 5 into a single unit, such as... Figure 1 , Figure 3 and Figure 4 As shown, the first connecting assembly 6 includes a first anchor bar 61. Semi-open through holes are formed at adjacent side ends of the two ALC plates 31, and the semi-open through holes of the two ALC plates 31 are joined to form a first mounting through hole 311. The upper and lower parts of the first anchor bar 61 are located inside the upper ring beam 2 and the lower ring beam 5, respectively, and the middle part of the first anchor bar 61 penetrates the first mounting through hole 311.
[0046] Specifically, the first anchor bar 61 has a U-shaped structure. The upper and lower parts of the first anchor bar 61 are parallel to the upper ring beam 2 and the lower ring beam 5, and are located inside the upper ring beam 2 and the lower ring beam 5, respectively. The middle part of the first anchor bar 61 passes through the first mounting through hole 311.
[0047] To further strengthen the connection between the ALC plate 3 and the upper ring beam 2 and lower ring beam 5, and to enhance the mechanical interlocking at the joint, such as... Figure 5 As shown, the first connecting assembly 6 also includes a plurality of first connecting members 62. A plurality of first connecting members 62 are arranged at intervals along the length direction of the upper and lower ends of the ALC plate 3. The plurality of first connecting members 62 are all arranged vertically. One end of the first connecting member 62 is located inside the upper ring beam 2 or the lower ring beam 5, and the other end is located inside the ALC plate 3.
[0048] Preferably, such as Figure 5 As shown, the first connector 62 is a pin. The flat end of the pin is located inside the upper ring beam 2 or the lower ring beam 5, and the pointed end of the pin is located inside the ALC plate 3. Of course, the first connector 62 can also be other structures, as long as it can enhance the mechanical engagement between the ALC plate 3 and the upper ring beam 2 and the lower ring beam 5.
[0049] In a preferred embodiment of this utility model, the number of the first connecting components 6 is 2 sets.
[0050] In order to horizontally connect each ALC plate 31 and the structural columns 4 on both sides into one unit, such as Figure 6As shown, the second connecting assembly 7 includes a lateral tightening screw 71 and two tightening nuts 72. Each ALC plate 31 has a second mounting through hole 312 in the horizontal direction. The lateral tightening screw 71 connects adjacent ALC plates 31 sequentially through the second mounting through holes 312. The tightening nuts 72 at both ends of the lateral tightening screw 71 engage with the tightening screws to tighten multiple ALC plates 31, forming a complete ALC plate 3. The two ends of the lateral tightening screw 71 and the two tightening nuts 72 are located in the structural columns 4 on both sides of the complete ALC plate 3.
[0051] To prevent stress concentration at the contact surface caused by directly tightening the tightening nut 72, which could lead to the crushing of the ALC plate 31, such as... Figure 6 As shown, the second connecting assembly 7 also includes two gaskets 74, which are respectively sleeved on both ends of the transverse tightening screw 71 and located between the ALC plate 3 and the tightening nut 72 to expand the force-bearing area.
[0052] To further strengthen the connection between the ALC slab 3 and the structural column 4, and to enhance the mechanical interlocking at their junction, such as... Figure 7 As shown, the second connecting assembly 7 also includes a plurality of second connectors 73. A plurality of second connectors 73 are arranged at intervals along the vertical direction of the side of the ALC plate 3. The plurality of second connectors 73 are all arranged horizontally. One end of the second connector 73 is located inside the structural column 4, and the other end is located inside the ALC plate 3.
[0053] Preferably, such as Figure 7 As shown, the second connector 73 is a pin, with its flat end located inside the structural column 4 and its pointed end located inside the ALC plate 3. Of course, the second connector 73 can also be other structures, as long as they enhance the mechanical engagement between the ALC plate 3 and the structural column 4 at their junction.
[0054] To reconcile the deformation differences between ALC plate 31 and structural column 4, such as Figure 6 and Figure 7 As shown, the second connecting component 7 also includes an alkali-resistant fiberglass mesh 75, which covers the connection between the ALC panel 3 and the structural column 4 to distribute stress to the entire alkali-resistant fiberglass mesh 75 and inhibit crack propagation.
[0055] In a preferred embodiment of this utility model, the number of second connecting components 7 is 3 sets. For example... Figure 1 As shown, the second connecting components 7 are arranged in parallel at intervals on the ALC board 3, and are respectively arranged at the top, middle and bottom positions of the ALC board 3.
[0056] To further enhance the integrity of the lower ring beam 5 and structural column 4, such as Figure 1 and Figure 2As shown, the lightweight partition wall for modular buildings that is easy to dismantle and modify also includes multiple vertically arranged second anchor bars 8. One end of the second anchor bar 8 is set inside the structural column 4, and the other end is set inside the lower ring beam 5 to connect the structural column 4 and the lower ring beam 5.
[0057] Preferably, such as Figure 1 As shown, the second anchor bar 8 has an L-shaped structure. The horizontal end of the second anchor bar 8 is located inside the lower ring beam 5, and the vertical end of the second anchor bar 8 is located inside the structural column 4 and the lower ring beam 5.
