Description

Technical Field

[0001] This invention relates to the field of prefabricated buildings, and more particularly to a quick-installation lightweight keel wall system with high airtightness and high watertightness. Background Technology

[0002] Traditional light steel keel walls often use flat splicing or simple overlapping methods, sealed on the outside with sealant. This connection method has through gaps, and when the sealant ages, rainwater can directly seep into the room. Especially in humid or rainy environments, moisture can easily penetrate through the joints, leading to problems such as internal corrosion and mold, affecting structural safety and service life. Furthermore, this connection method is prone to micro-deformation under extreme temperature differences or vibrations, causing joint misalignment and seal failure, resulting in substandard airtightness and watertightness. This method of sealing with external sealant cannot allow for repeated disassembly and reuse of the wall. Most light steel keel walls use fixed connections (such as welding and riveting), which can easily damage the keel or finishing layer during disassembly, making modular maintenance or flexible space adjustment difficult. Summary of the Invention

[0030] like Figure 1 As shown, the quick-installation lightweight keel wall system with high airtightness and high watertightness performance includes at least two wall panels 100. A tongue-and-groove assembly 200 is provided between two adjacent wall panels 100 to seal the gap between them. The two adjacent wall panels 100 are connected by at least one sealing and pressing connection assembly 300. The sealing and pressing connection assembly 300 includes two wall connectors 310, a tensioning connector 320, and two adjusting members 330. The two wall connectors 310 are connected to the two adjacent wall panels 100 in a one-to-one correspondence, and the tensioning connectors 320 are connected to the two wall connectors 310. The adjusting members 330 are connected to the tensioning connectors 320 and the corresponding wall connectors 310. The adjusting members 330 are used to change the position of the corresponding wall connectors 310 relative to the tensioning connectors 320 to change the gap between the two adjacent wall panels 100.

[0031] The present invention provides a quick-installation lightweight keel wall system with high airtightness and watertightness, which improves the assembly efficiency of the wall system, enables quick installation and disassembly without damaging the main structure, completely eliminates any wet work, and facilitates modular maintenance or flexible space adjustment. By setting a tongue-and-groove component 200 between two adjacent wall sections 100, the tongue-and-groove component 200 seals the gap between the two adjacent wall sections 100. By adjusting the position of the corresponding wall connector 310 relative to the tension connector 320 through the adjusting component 330, the gap between the two adjacent wall sections 100 is changed, so that the tongue-and-groove component 200 presses the sealing strip 230. This assembly method not only improves the sealing performance of the wall section 100, but also effectively improves the installation accuracy of the quick-installation lightweight keel wall section 100, avoiding problems such as uneven wall surface installation and joint cracking caused by splicing of the wall section 100.

[0032] In one embodiment of the present invention, such as Figure 1 , Figures 6 to 8 As shown, the wall connector 310 is provided with a first threaded hole 311, and the tension connector 320 is provided with a strip-shaped through hole 321. The strip-shaped through hole 321 extends along the width direction of the wall 100, that is, along... Figure 1 Extending left and right in the middle, a fixing bolt 322 is provided in the strip-shaped through hole 321, which is threaded into the first threaded hole 311. When the fixing bolt 322 is loosened, the position of the corresponding wall connector 310 relative to the tension connector 320 can be changed by adjusting the adjusting component 330, thereby changing the gap between the convex tongue and groove 210 and the concave tongue and groove 220, and thus changing the pressure on the sealing strip 230. By fine-tuning the position of the wall connector 310 by adjusting the adjusting component 330, the size of the gap between the convex tongue and groove 210 and the concave tongue and groove 220 can be precisely controlled, thereby ensuring that the sealing strip 230 can be evenly pressurized and achieve a good sealing effect. This adjustability not only improves the air tightness and water tightness of the wall 100, but also enhances the overall stability and reliability of the wall 100 system. By precisely controlling the pressure on the sealing strip 230 through the adjusting component 330, it is ensured that the sealing strip 230 operates within a reasonable pressure range, avoiding damage caused by excessive compression or stretching, thereby extending the service life of the sealing strip 230 and thus improving the service life of the entire wall system 100. When the fixing bolt 322 is fixed, the wall connector 310 is fixed to the tension connector 320, and the gap between the protruding tongue and groove 210 and the concave tongue and groove 220 no longer changes.

[0033] Since the wall connector 310 and the tension connector 320 are connected by fixing bolts 322, a detachable connection between two adjacent walls 100 is realized. After the wall 100 is made, it can be assembled on site without the need to install the keel 130, insulation and decorative panels on site. It is especially suitable for prefabricated houses or mobile buildings that require repeated disassembly and assembly.

[0034] Furthermore, the wall connector 310 is integrally formed with the wall 100. The wall connector 310 and the wall 100 are formed simultaneously during the manufacturing process, eliminating the need for additional connector installation steps, which greatly improves production efficiency and reduces production costs.

[0035] In one embodiment of the present invention, such as Figure 7 As shown, the adjusting component 330 includes an adjusting bolt, the wall connector 310 is provided with a second threaded hole 312, and the tensioning connector 320 is provided with a third threaded hole 323. The adjusting bolt is arranged along the width direction of the wall 100, and the adjusting bolt is threadedly engaged with the second threaded hole 312 and the third threaded hole 323. When the adjusting bolt is rotated, the position of the corresponding wall connector 310 relative to the tensioning connector 320 can be changed under the action of the threads.

[0036] The adjusting bolts simplify and precisely adjust the position between the wall connector 310 and the tensioning connector 320. By rotating the adjusting bolts, the wall connector 310 can be fine-tuned in the width direction of the wall 100, thereby precisely controlling the gap between adjacent walls 100. This precise adjustment capability effectively solves sealing problems caused by dimensional errors or construction deviations during the installation of the wall 100, ensuring that the airtightness and watertightness of the wall 100 meet design requirements and significantly improving the overall performance of the wall 100. During the installation of the wall 100, various complex situations may be encountered, such as inconsistent flatness of the wall 100 and minor deviations in installation position. The fine-tuning function of the adjusting bolts allows construction workers to quickly adapt to these changes without large-scale disassembly or reprocessing of the wall 100, thus greatly improving construction efficiency and reducing construction costs.

[0037] In one embodiment of the present invention, such as Figure 7As shown, the sealing and clamping connection assembly 300 also includes a column clamping member 340, which is U-shaped or C-shaped. Both ends of the column clamping member 340 are connected to the tensioning connection member 320 by bolts to clamp the column 350 between the column clamping member 340 and the tensioning connection member 320. To improve the connection strength between two adjacent wall sections 100, the two adjacent wall sections 100 are connected by two sealing and clamping connection assemblies 300. The two sealing and clamping connection assemblies 300 are arranged at intervals along the height direction of the wall section 100, and both sealing and clamping connection assemblies 300 are connected to the column through the column clamping member 340. The column clamping member 340 significantly enhances the connection strength between the wall 100 and the column. By firmly clamping the column between the column clamping member 340 and the tensioning connector 320, the connection between the wall 100 and the column becomes more stable, effectively resisting external forces such as horizontal loads and seismic forces, thereby improving the overall seismic and wind resistance performance of the wall 100 system. Furthermore, the column clamping member 340 and the tensioning connector 320 are connected by bolts. This detachable connection method not only facilitates installation and disassembly but also allows adjustment of the clamping force between the column clamping member 340 and the column according to actual needs, further enhancing the reliability of the connection between the wall 100 and the column.

[0038] In one embodiment of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the tongue-and-groove assembly 200 includes a convex tongue-and-groove 210 and a concave tongue-and-groove 220. The convex tongue-and-groove 210 is disposed on the side of one wall 100 closer to the other wall 100 in two adjacent wall sections 100; the concave tongue-and-groove 220 is disposed on the side of the other wall 100 closer to the first wall 100 in two adjacent wall sections 100. Specifically, as... Figure 5 As shown, a raised tongue-and-groove joint 210 is located on the left side of the right wall 100, and a recessed tongue-and-groove joint 220 is located on the right side of the left wall 100. When the walls 100 are joined, the raised tongue-and-groove joint 210 and the recessed tongue-and-groove joint 220 interlock. To facilitate joining with other walls 100, a raised tongue-and-groove joint 210 is located on the left side of the left wall 100, and a recessed tongue-and-groove joint 220 is located on the right side of the right wall 100. Both the raised tongue-and-groove joint 210 and the recessed tongue-and-groove joint 220 are made of materials with low thermal conductivity and a certain strength, such as rigid PVC or polycarbonate plastic. The material of the raised tongue-and-groove joint 210 and the recessed tongue-and-groove joint 220 is determined according to the thickness of the wall 100, and they are made of solid material.

[0039] Using convex tongue and groove joint 210 and concave tongue and groove joint 220 as edge sealing materials has the following advantages: First, the tongue and groove joints 210 and 220 are made of insulation material 140, which effectively blocks heat conduction. In the traditional wall structure 100, the edge joists 130 are usually made of metal materials, which have high thermal conductivity and are prone to forming cold bridges, leading to heat loss and indoor temperature fluctuations. This invention uses a material with low thermal conductivity as the edge sealing material, which can significantly reduce the cold bridge effect, reduce heat transfer, and thus improve the thermal insulation performance of the wall 100.

[0040] Secondly, the convex tongue and groove joint 210 and the concave tongue and groove joint 220 are made of solid materials, which have high strength and stability. They can not only withstand the pressure during the splicing of the wall 100, but also maintain the structural integrity of the wall 100 during its use, avoiding sealing failure due to material deformation or damage. In addition, the use of solid materials also enhances the impact resistance of the tongue and groove joint, making it better adaptable to complex construction environments and usage conditions.

[0041] Finally, the convex tongue and groove joint 210 and the concave tongue and groove joint 220 are in close contact, forming a good sealing effect. This sealing method can not only effectively prevent air penetration, but also prevent moisture intrusion, thereby further improving the waterproof performance of the wall 100 and extending the service life of the wall 100.

[0042] In one embodiment of the present invention, such as Figure 3 As shown, a sealing strip 230 is provided on the side of the protruding tongue and groove 210 facing the concave tongue and groove 220. There are three sealing strips 230. The three sealing strips 230 are arranged at intervals along the thickness direction of the wall 100 and extend along the height direction of the wall 100. The material of the sealing strip 230 is EPDM rubber, but it can also be other materials.

[0043] In one embodiment of the present invention, such as Figure 2 As shown, the wall 100 includes an interior panel 120, an exterior panel 110, at least two joists 130, and insulation material 140. The exterior panel 110 is parallel to and spaced apart from the interior panel 120. At least two joists 130 are spaced apart between the exterior panel 110 and the interior panel 120. In this embodiment, two joists 130 are provided between the exterior panel 110 and the interior panel 120. Of course, the number of joists 130 is not limited to this; it can also be three, four, or more. The spaced arrangement of the joists 130 not only provides sufficient support for the wall 100 but also effectively disperses the external forces on the wall 100, avoiding deformation or damage caused by excessive local stress. Two keels 130 are set in parallel, and the insulation material 140 is set between the two adjacent keels 130. The insulation material 140 fills the gap between the keels 130 to form a continuous insulation layer, which effectively blocks the heat transfer path and reduces heat loss, thereby significantly improving the insulation performance of the wall 100.

[0044] In one embodiment of the present invention, such as Figure 2 As shown, both the exterior trim panel 110 and the interior trim panel 120 have a connecting edge 150 that protrudes relative to the keel 130. Specifically, the left side of both the exterior trim panel 110 and the interior trim panel 120 protrudes relative to the keel 130 to form a connecting edge 150, and the right side of both the exterior trim panel 110 and the interior trim panel 120 protrudes relative to the keel 130 to form a connecting edge 150. The width of each connecting edge 150 is equal, and the width of the connecting edge 150 between the exterior trim panel 110 and the interior trim panel 120 is equal. In this embodiment, the width of the connecting edge 150 is 10-15mm.

[0045] Two recessed cavities 211 are provided on both the side of the protruding tongue and groove joint 210 facing the wall 100 and the side of the recessed tongue and groove joint 220 facing the wall 100. The depth of the recessed cavities 211 is 10-15mm. The connecting edges 150 of the exterior trim panel 110 and the interior trim panel 120 are respectively inserted into the corresponding recessed cavities 211, thereby realizing a quick connection between the wall 100 and the protruding tongue and groove joint 210 and the recessed tongue and groove joint 220. By providing protruding connecting edges 150 on both sides of the interior trim panel 120 and the exterior trim panel 110, and having them inserted into the recessed cavities 211 of the protruding tongue and groove joint 210 and the recessed tongue and groove joint 220, a quick connection between the wall 100 and the tongue and groove assembly 200 is achieved. This snap-fit ​​connection method not only simplifies the installation process, but also reduces the reliance on tools during installation, making the splicing of the wall 100 more efficient and convenient. Construction workers can quickly complete the assembly of the wall 100, greatly shortening the construction time and improving construction efficiency.

[0046] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the sidewall of the cavity 211 is provided with multiple elastic limiting members 212, and the connecting edge 150 is provided with multiple recesses 160. The multiple elastic limiting members 212 are embedded in the multiple recesses 160 one by one. Specifically, the elastic limiting member 212 includes a compression spring and a small ball. The sidewall of the cavity 211 is provided with multiple grooves. The distance between the groove and the outer edge of the cavity 211 is 5mm. The multiple grooves are arranged at intervals along the height direction of the wall 100. The compression spring is placed in the groove, and the small ball is placed at the opening of the groove. The opening diameter of the groove is smaller than the diameter of the small ball. The small ball abuts against the compression spring, so that part of the small ball protrudes from the opening of the groove. Multiple recesses 160 are arranged at intervals along the height direction of the wall 100. The distance between two adjacent recesses 160 is 50-100mm, and the distance between a recess 160 and the keel 130 is 5mm. The position of the recesses 160 corresponds one-to-one with the position of the elastic limiting member 212. The depth of the recesses 160 is 1-2mm.

[0047] When the connecting edge 150 is inserted into the corresponding cavity 211, the ball embeds itself into the corresponding groove, forming a self-locking mechanism. This self-locking mechanism not only effectively prevents the wall 100 from loosening due to vibration or external forces during use, but also ensures a tight connection between the wall 100 and the tongue-and-groove assembly 200, thereby improving the overall strength and stability of the wall 100. Furthermore, this connection method eliminates the need for additional fasteners or complex installation tools; simply inserting the connecting edge 150 into the cavity 211 causes the ball to automatically embed into the recess 160, achieving a quick connection. This quick connection method simplifies the installation process, reduces installation time, and improves construction efficiency, making it particularly suitable for the rapid construction of large-scale prefabricated buildings.

[0048] In one embodiment of the present invention, such as Figure 2 As shown, multiple recesses 160 are distributed on both sides of the connecting edge 150 and spaced apart along the height direction of the wall 100, with the recesses 160 on both sides of the connecting edge 150 arranged alternately. Compared to aligning the recesses 160 on both sides of the connecting edge 150 in a straight line, arranging the recesses 160 alternately on both sides of the connecting edge 150 has the following two advantages: Firstly, the alternating arrangement of the recesses 160 allows for a deeper recess without increasing the panel thickness, enabling the elastic limiting member 212 (such as a small ball) to be more firmly embedded in the recess 160, thereby providing stronger connection strength and stability. The deeper recesses 160 not only enhance the connection reliability between the wall 100 and the tongue-and-groove assembly 200, but also effectively prevent loosening of the connection due to external impact or vibration, further improving the overall performance of the wall 100 system.

[0049] On the other hand, the alternating arrangement of the recesses 160 on both sides of the connecting edge 150 can make the stress distribution between the wall 100 and the tongue and groove assembly 200 more uniform, which can disperse the stress and make the stress of the wall 100 more evenly distributed throughout the connecting area when subjected to external force. It also improves the overall deformation resistance of the wall 100, so that it can maintain good stability under various usage conditions.

[0050] The following is combined with Figures 1 to 8 A method for assembling a quick-installation lightweight keel wall with high airtightness and high watertightness is described in a specific embodiment: The exterior panel 110 and the interior panel 120 have a connecting edge 150 that protrudes relative to the keel 130. The width of the connecting edge 150 is 10mm. The recesses 160 on both sides of the connecting edge 150 are arranged alternately. Multiple recesses 160 are arranged at equal intervals along the height direction of the wall 100. The distance between the recess 160 and the keel 130 is 5mm. The distance between two adjacent recesses 160 is 100mm. The depth of the recess 160 is 2mm.

[0051] In the production process, the exterior trim panel 110 is first laid flat. The keel 130 is then placed on top of the exterior trim panel 110 at the designed spacing. Next, the interior trim panel 120 is laid flat on top of the keel 130. The connecting edge 150 of one side of the interior trim panel 120 and the exterior trim panel 110 is inserted into the cavity 211 of the protruding tongue and groove 210. The connecting edge 150 of the other side of the interior trim panel 120 and the exterior trim panel 110 is inserted into the cavity 211 of the recessed tongue and groove 220, allowing the small ball to embed into the corresponding recess 160, thus achieving the connection between the wall 100 and the protruding tongue and groove 210 and the recessed tongue and groove 220. Foamed polyurethane is poured into the wall 100 through the pouring port. The interior trim panel 120, the exterior trim panel 110, and the keel 130 are bonded and positioned by the polyurethane. The protruding tongue and groove 210 and the recessed tongue and groove 220 serve as templates for polyurethane pouring, filling the cavities with polyurethane. After pouring, a complete, straight wall 100 is formed.
