Abstract
Description
Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to an ALC lightweight partition wall for use in modular buildings and a building module having the same. Background Technology
[0002] In the field of modular concrete building technology, autoclaved lightweight concrete (ALC) panels are commonly used as lightweight partition materials for the internal walls of modules. Their primary function is to separate different building spaces. These panels are generally installed on-site during the finishing stage after the prefabricated modules are completed, and ALC panels are often joined using a dry-joint method, with joint treatment to achieve a smooth surface.
[0003] However, while this construction method performs quite well in traditional building projects, it faces challenges in modular construction due to the transportation and hoisting of modular units. Specifically, due to the inertial forces during transportation and the weight of the modules during hoisting, the joints between ALC panels are prone to cracking. This not only affects the finishing quality, acceptance standards, and appearance of the modular units, but in severe cases, it can also damage the panels themselves, resulting in unnecessary economic losses.
[0004] Furthermore, traditional dry-joint methods rely on precise alignment and rigid fasteners such as bolts or nails, which require drilling into the ALC sheet, increasing the risk of damage. Moreover, during long-distance transport or hoisting operations in complex terrain, vibration and impact can further exacerbate stress concentration at the joints between the sheets, leading to crack propagation and even sheet breakage.

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a lightweight partition wall for modular buildings, which solves the technical problem that traditional lightweight partition walls mostly use dry connection methods, resulting in cracking during transportation due to inertial forces and the self-weight of the modules during hoisting.

[0018] (III) Beneficial Effects
[0019] The beneficial effects of this utility model are:

[0028] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.
[0029] Example 1
[0030] like Figure 1 , Figure 2 and Figure 4 As shown in this embodiment, an ALC lightweight partition wall for modular buildings includes multiple partition wall bodies 4 connected sequentially. A grouting space 41a is provided at the connection point of adjacent partition wall bodies 4 for grouting. Grouting material 6 for connecting two adjacent partition wall bodies 4 can be injected into the grouting space 41a. The grouting space 41a is formed by a grouting channel 41 vertically opened on the side wall of the partition wall body 4. By providing grouting spaces 41a between adjacent partition wall bodies 4 and filling and fixing them with grout 6, the structural strength and stability of the ALC lightweight partition wall are effectively improved, reducing the risk of displacement or damage caused by external factors. Its wet connection method not only achieves a stable connection between the partition wall bodies 4 but also avoids joint cracking caused by inertial forces during transportation and the self-weight of the modules during hoisting, improving the overall quality of the modular building. It also significantly reduces the risk factor during transportation and the maintenance cost of the modular building, possessing significant engineering application value, thereby improving the decoration quality, acceptance standards, and appearance of the modular building. Meanwhile, by combining modular design with on-site grouting, the advantages of rapid installation of modular buildings are maintained, while ensuring flexibility and adaptability on the construction site, thus improving installation efficiency. Chamfers are provided at all four corners of the partition wall body 4 to prevent cracking caused by mutual compression between adjacent partition wall bodies 4 during transportation, especially at the four corners where cracking is highly likely due to mutual compression, thereby reducing the damage rate of the partition wall body 4.
[0031] Furthermore, the transverse cross-section of the grouting channel 41 is semi-circular, which helps guide the grout 6 to flow evenly and fully fill the entire grouting space 41a. Compared to square or other shaped cross-sections, the semi-circular grouting channel 41 reduces the resistance of the grout 6 during the filling process, ensuring that the grout 6 can flow smoothly and unobstructedly to fill every corner, thereby improving the connection quality. The diameter of the grouting space 41a ranges from 40mm to 50mm, which ensures optimal material utilization while maintaining structural strength, so as to accommodate sufficient grout 6. It should be noted that the transverse cross-section of the grouting channel 41 can also be other shapes, but semi-circular is preferred.
[0032] Furthermore, such as Figure 2 As shown, the ALC lightweight partition wall is also provided with a joint space 41b. The joint space 41b is located at the joint of each two adjacent partition wall bodies 4. The joint space 41b is coated with a filling material 7 for sealing the joint space 41b. It can not only effectively prevent moisture and other liquids from penetrating into the interior of the partition wall body 4, but also smooth the joint between adjacent partition wall bodies 4 and prevent grout leakage during subsequent grouting operations.
[0033] Furthermore, such as Figure 2 , Figure 4 and Figure 5 As shown, the chamfers at the four corners of the partition wall body 4 are obtuse angles. This prevents adjacent partition wall bodies 4 from cracking due to mutual compression during transportation, especially at the four corners where cracking is highly likely to occur. This reduces the damage rate of the partition wall body 4. Compared to sharp right angles, obtuse angles reduce stress concentration and lower the risk of cracking caused by external forces during transportation and hoisting, thereby improving the overall durability and safety of the partition wall body 4.
[0034] This embodiment features vertically extending grouting grooves 41 on both side walls of each partition wall body 4. The two grouting grooves 41 between adjacent partition wall bodies 4 together form a grouting space 41a. This transforms the current dry connection between adjacent partition wall bodies 4 into a wet connection, avoiding drilling holes in the ALC lightweight partition wall and preventing cracking during hoisting and transportation, thus reducing the risk of damage. Furthermore, by chamfering the four corners of the partition wall body 4, cracking and damage to the ALC lightweight partition wall caused by corner-to-corner compression during hoisting and transportation are prevented. This effectively avoids stress concentration at the joints of the ALC lightweight partition wall, preventing crack propagation or even breakage. Additionally, a filler material 7 is applied to the grouting space 41b, making the connection between adjacent partition wall bodies 4 more secure and robust. It should be noted that the filler material can be an ALC-specific grout.
[0035] Example 2
[0036] like Figure 1 As shown, a building module with ALC lightweight partition wall in this embodiment includes the ALC lightweight partition wall in embodiment one, and also includes a top plate 1, a bottom plate 3 and a wall panel 2 connecting the top plate 1 and the bottom plate 3.
[0037] Specifically, the top plate 1 and the bottom plate 3 correspond to the top and bottom of the ALC lightweight partition wall, respectively. Both the top plate 1 and the bottom plate 3 are equipped with multiple vertically arranged connectors 5. Each connector 5 on the top plate 1 corresponds one-to-one with the connectors 5 on the bottom plate 3, ensuring that each connector 5 can be placed within the grouting space 41a. This makes the ALC lightweight partition wall more stable when connected to the top plate 1 and the bottom plate 3, improving the stability of the building module. Preferably, as follows... Figure 5 As shown, each connector 5 is placed at a depth of not less than 40mm within the top plate 1 and bottom plate 3, which greatly enhances the fixing effect of the connector 5, providing stronger pull-out resistance and higher shear strength. This makes the connection between the ALC lightweight partition wall and the top plate 1 and bottom plate 3 more robust and reliable, effectively improving the structural stability and safety of the modular building. Multiple connectors 5 on the top plate 1 and bottom plate 3 are respectively located within the grouting space 41a. By setting multiple vertically arranged connectors 5 on both the top plate 1 and bottom plate 3, and placing these connectors within the grouting space 41a, the multiple connectors 5 can also be wrapped around the grouting material 6 when it is injected into the grouting space 41a between two adjacent partition wall bodies 4. This improves the connection strength between the ALC lightweight partition wall and the top plate 1 and bottom plate 3, enhances the vertical structural stability of the entire building module, and makes the building module more robust and reliable.
[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the top and bottom of the partition wall body 4 are fixedly connected to the bottom of the top plate 1 and the top of the bottom plate 3 respectively through fixing material 8. This significantly improves the structural stability of the lightweight partition wall, ensuring that the partition wall can not only withstand vertical pressure but also effectively resist horizontal forces, thus improving the overall safety of the building. Compared with traditional complex connection methods, this reduces the time for on-site adjustment and calibration, improving work efficiency. The fixing material 8 includes polymer mortar and a special grout. During application, polymer mortar is first used to seal the gaps between the top plate 1 and bottom plate 3 and the ALC lightweight partition wall, and then the special grout is applied as a primer, thereby fixing the top plate 1 and bottom plate 3 to the ALC lightweight partition wall using the fixing material 8.
[0039] Furthermore, connector 5 is a connecting steel bar, which provides stronger tensile and shear strength, ensuring a firm connection between the partition wall bodies 4 and between the partition wall and the top slab 1, bottom slab 3, and wall panel 2. Connector 5 is coaxial with the grouting space 41a, which further enhances the consistency and stability of the overall structure and effectively improves the overall compressive and seismic performance of the building module.
[0040] Furthermore, the connector 5 has a diameter of 8mm-16mm, which provides sufficient tensile and shear strength while maintaining appropriate flexibility to adapt to various stress changes that may be encountered during the transportation and hoisting of modular buildings. The connector 5 has a length of 500mm-1000mm, forming a stable anchor point, enhancing the connection strength between the ALC lightweight partition wall and the building module, and improving the safety and stability of the overall structure. Currently, during on-site construction, connector 5 with a diameter of 8mm and a length of 700mm is generally selected, which is sufficient for the connection of most partition wall bodies 4.
[0041] Furthermore, such as Figure 3 As shown, the inner wall of wall panel 2 is connected to the leftmost partition wall body 4. The inner wall of wall panel 2 has a concave-convex mating surface 21, which can be roughened to increase the contact area between the wall and the grouting material 6. This ensures an effective connection between the partition wall body 4 and wall panel 2 when the grouting material 6 is subsequently injected into the grouting space 41a, increasing the adhesion between the grouting material 6 and the wall. The depth of the concave-convex mating surface 21 ranges from 4mm to 6mm, ensuring sufficient embedding depth for the grouting material 6. This increases the contact area between the grouting material 6 and the concave-convex mating surface 21 of wall panel 2, making the connection between the partition wall body 4 and the wall more compact and robust, thus significantly enhancing the stability of the modular building.
[0042] In this embodiment, multiple connectors 5 are pre-embedded on both the top plate 1 and the bottom plate 3, and each connector 5 is located within the grouting space 41a. When grouting is poured into the grouting space 41a, the grouting material 6 can wrap around the connector 5, thereby fixing the connector 5 within the grouting space 41a. This allows the ALC lightweight partition wall to be stably connected to the top plate 1 and the bottom plate 3. Furthermore, by grouting the leftmost partition wall body 4 to the inner wall of the wall with grouting material 6, and by providing a concave-convex joint surface 21 on the inner wall of the wall panel 2, the contact area between the grouting material 6 and the wall and the grouting channel 41 can be increased. This allows the ALC lightweight partition wall to form an integral structure with the top plate 1, wall panel 2, and bottom plate 3, thereby improving the structural stability of the ALC lightweight partition wall with the top plate 1, wall panel 2, and bottom plate 3, and making the building module more stable and safer.
[0043] Example 3
[0044] Based on the ALC lightweight partition wall in Example 1 and the building module in Example 2, the installation procedure is as follows:
[0045] The following describes the partition wall body 4 connected to the wall panel 2. First, the inner wall of the wall panel 2 is roughened to form a concave-convex joint surface 21, with a depth ranging from 4mm to 6mm. Then, holes are drilled at multiple corresponding positions at the bottom of the top plate 1 and the top of the bottom plate 3, and a connector 5 is inserted into each hole. Part of the connector 5 is pre-embedded and fixed within the top plate 1 and the bottom plate 3, with a pre-embedded length of not less than 40mm, while the other part extends beyond the bottom of the top plate 1 and the top of the bottom plate 3. After the connector 5 is fixed, a partition wall body 4 is placed on the bottom plate 3, and the connector 5 is placed within the grouting groove 41 and coaxially aligned. Meanwhile, the top and bottom of the partition wall body 4 are fixed to the bottom of the top plate 1 and the top of the bottom plate 3 respectively using mortar. Then, the gaps between the top and bottom of the partition wall body 4 and the bottom of the top plate 1 and the top of the bottom plate 3 are sealed and leveled using fixing material 8. That is, polymer mortar is first used to seal the gaps, and then a special grouting agent is used to apply a base coat and level it. Then, the grouting space 41b between the wall panel 2 and the partition wall body 4 is filled and connected by filling material 7, thereby leveling the grouting space 41b and preventing grout leakage during grouting. Finally, after filling is completed, grouting material 6 is injected into the grouting space 41a using a special grouting gun. Grouting material 6 is mixed on-site with masonry mortar and has a strength of not less than M7.5. After grouting material 6 is completely air-dried, the connection between the leftmost partition wall body 4 and the wall panel 2 is completed.
