Description

Technical Field

[0001] This application belongs to the field of building structure technology, and specifically relates to wall systems. Background Technology

[0002] Wall systems are comprehensive structural systems used in construction for the enclosure, decoration, and protection of interior and exterior walls. They typically consist of a base layer, a functional layer, and a decorative layer. Among these, sandwich panel wall systems integrate insulation and decoration, making them a widely used wall construction method in the construction industry. In existing sandwich panel wall systems, the panels are usually laid horizontally, and a strip is used to cover the seam between two horizontal panels. The strip is pressed tightly between the two panels to form a seal, which can solve the problem of water seepage in the seam to some extent. However, over time, material aging or deformation can cause the strip to lose its seal, significantly increasing the likelihood of water seepage. Therefore, frequent inspections and maintenance by construction personnel are required, resulting in high maintenance costs. Utility Model Content

[0003] In view of at least one of the above-mentioned defects or deficiencies in the prior art, this application provides a wall system that is beneficial to enhance the waterproof structure of the wall, improve the waterproof effect, and reduce maintenance costs.

[0004] To achieve the above objectives, this application provides a wall system comprising:

[0005] Purlins;

[0006] Multiple wall sandwich panels are spliced ​​and laid on the purlins;

[0007] Tongue and groove joints are formed between two wall sandwich panels that are vertically joined together;

[0008] The center seam is formed between two wall sandwich panels that are spliced ​​together laterally and intersects with the tongue and groove joint;

[0009] A fastening strip assembly covers the center seam from the outside of the wall sandwich panel and has its side edges overlapping the wall sandwich panel on both sides of the center seam;

[0010] Adhesive tape, used to bond the fastener assembly to the wall sandwich panel; and

[0011] A sealing block is used to fill the junction of the tongue and groove and the center seam.

[0012] In some embodiments, the outer end face of the sealing block is flush with the outer surface of the wall sandwich panel, and the side edge of the fastening strip assembly overlaps the wall sandwich panel and covers the sealing block.

[0013] In some embodiments, the tape is also adhered between the fastener assembly and the sealing block.

[0014] In some embodiments, the vertical ends of the sealing block abut against the respective ends of the two wall sandwich panels that are vertically spliced ​​together.

[0015] In some embodiments, the tape is a butyl tape.

[0016] In some embodiments, the sealing block is a foam sealing block.

[0017] In some embodiments, the fastener assembly includes:

[0018] The fastener body includes a fastener insert portion embedded in the central seam and side edge portions overlapping both sides of the central seam;

[0019] The fastener is threaded through the fastener insert and the purlin.

[0020] In some embodiments, the fastener assembly further includes:

[0021] The buckle cover has a buckle groove formed on the outer side of the buckle insert portion. The buckle cover is fastened in the buckle groove and is used to cover the buckle connecting piece.

[0022] In some embodiments, in the vertically spliced ​​first wall sandwich panel and second wall sandwich panel, the splicing portion of the first wall sandwich panel has a tenon, and the splicing portion of the second wall sandwich panel has a groove. The tenon and the groove are interlocked. The outer side of the tenon has a step. The groove and the step define the tongue and groove joint.

[0023] In some embodiments, the wall system further includes a sandwich panel connector that passes through and fixes the tenon to the purlin, the groove covering the sandwich panel connector.

[0024] In the wall system of this application, by adding adhesive tape between the fastener assembly and the wall sandwich panel, the fit between the fastener assembly and the wall sandwich panel is improved, effectively preventing rainwater from seeping into the cavity through the joint. Simultaneously, the tape forms a continuous, flexible sealing layer, effectively compensating for gap widening caused by thermal expansion and contraction or deformation between the two materials, enhancing the environmental adaptability of the wall system, extending its service life, and reducing maintenance costs. Furthermore, by setting a sealing block at the intersection of the tongue and groove joint and the joint, the seepage path can be effectively blocked, preventing rainwater from seeping into the joint through the tongue and groove joint, further improving the waterproofing effect of the wall system.

[0025] Other features and advantages of the embodiments of this application will be described in detail in the following detailed description section. Attached Figure Description

[0031] Detailed Implementation

[0032] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0033] The present application will now be described in detail with reference to the accompanying drawings and exemplary embodiments.

[0034] like Figures 1 to 3As shown, an exemplary embodiment of this application provides a wall system, which mainly includes purlins 1, multiple wall sandwich panels 2, tongue and groove joints 3, center seams 4, fastening strips 5, adhesive tape 6, and sealing blocks 7. The purlins 1 are used to fix the wall substrate. Multiple wall sandwich panels 2 are spliced ​​and laid on the purlins 1. A tongue and groove joint 3 is formed between two wall sandwich panels 2 spliced ​​vertically. A center seam 4 is formed between two wall sandwich panels 2 spliced ​​horizontally. The center seam 4 intersects with the tongue and groove joint 3. In other words, the wall sandwich panels 2 are rectangular sandwich panels. When splicing, the right-angled sides of the rectangular sandwich panels are aligned in pairs to form mutually perpendicular center seams 4 and tongue and groove joints 3. Both can be regarded as splicing seams of the sandwich panels. The fastening strip assembly 5 covers the center seam 4 from the outside of the wall sandwich panel 2. The side edges of the fastening strip assembly 5 overlap the wall sandwich panels 2 on both sides of the center seam 4. In other words, the fastening strip assembly 5 spans the center seam 4 and overlaps the wall sandwich panels 2 on both sides, thereby covering the center seam 4 for waterproofing. Adhesive tape 6 is applied between the fastening strip assembly 5 and the wall sandwich panel 2, and sealing block 7 fills the junction of the tongue and groove joint 3 and the center seam 4.

[0035] See Figure 2 The tape 6 is installed along the edge of the wall sandwich panel 2. When the fastener assembly 5 is aligned with the center seam 4, the two sides of the fastener assembly 5 are pressed against the tape 6, thus seamlessly connecting the edges of the fastener assembly 5 with the wall sandwich panel 2, achieving a higher degree of fit and effectively preventing rainwater from seeping into the wall from the joint between the fastener assembly 5 and the wall sandwich panel 2. Simultaneously, the tape 6 has the characteristics of a flexible material. When the fastener assembly 5 deforms due to thermal expansion and contraction or impact, causing the gap to widen, the tape 6 can compensate and fill the widened gap in a timely manner, preventing leakage at that location. This improves the environmental adaptability of the wall system, extends its service life, and reduces later maintenance costs.

[0036] See Figure 1 and Figure 3 The sealing block 7 is set at the end of the tongue and groove joint 3, which is the junction of the tongue and groove joint 3 and the middle seam 4. Therefore, the sealing block 7 can block the connection between the tongue and groove joint 3 and the middle seam 4, prevent rainwater from flowing into the middle seam 4 from the tongue and groove joint 3, and then seep into the inner wall, thereby further improving the waterproof effect of the wall system.

[0037] In this embodiment, the wall sandwich panels 2 are laid horizontally. Correspondingly, the purlins 1 may include horizontal purlins 101 and vertical purlins 102. The horizontal purlins 101 are fixedly laid on the wall or other fixed structure, and the vertical purlins 102 are laid alternately on the horizontal purlins 101. Two wall sandwich panels 2 that are spliced ​​together horizontally are both installed on the same vertical purlin 102, so that the center seam 4 is aligned with the vertical purlin 102.

[0038] The outer end face of the sealing block 7 at least partially abuts against the inner side of the fastener assembly 5, thereby ensuring that there is no gap between the sealing block 7 and the fastener assembly 5 that communicates with the tongue and groove 3, preventing rainwater from seeping in from between the sealing block 7 and the fastener assembly 5. The sealing block 7 can be a small piece only located at the end of the tongue and groove 3, or it can be a strip extending laterally from the end of the tongue and groove 3. Moreover, the sealing block 7 can be filled into the tongue and groove 3 through various processes. For example, when using a foam sealing block 7, the sealing block 7 can be directly inserted into the tongue and groove 3. When using an adhesive sealing block 7, the sealing block 7 can be formed in the tongue and groove 3 by dispensing adhesive. These details will not be elaborated further here.

[0039] Furthermore, the outer end face of the sealing block 7 is flush with the outer surface of the wall sandwich panel 2, and the outer edge of the fastening strip assembly 5 overlaps the wall sandwich panel 2 and covers the sealing block 7. This design, where the two interfaces of the sealing block 7 and the wall sandwich panel 2 are flush, prevents the sealing block 7 from protruding outwards, thus avoiding gaps formed by the fastening strip assembly 5 overlapping the wall sandwich panel 2 and preventing leaks.

[0040] When the outer end face of the sealing block 7 abuts against the inner side of the snap strip assembly 5, the tape 6 is also adhered between the snap strip assembly 5 and the sealing block 7. In other words, the tape 6 is not only set on the edge of the wall sandwich panel 2, but also on the outer end face of the sealing block 7, so that the snap strip assembly 5 and the sealing block 7 form a seamless connection, further ensuring the waterproof effect.

[0041] When the sealing block 7 is a prefabricated component, the sealing block 7 is inserted entirely into the tongue and groove 3. At this time, the vertical ends of the sealing block 7 respectively abut against the ends of the two wall sandwich panels 2 that are spliced ​​together vertically. This design can prevent the sealing block 7 from moving laterally and fix the sealing block 7 relative to the wall sandwich panel 2. On the other hand, it can eliminate the gap between the sealing block 7 and the wall sandwich panel 2 and completely prevent the tongue and groove 3 from connecting with the middle seam 4, so as to ensure the waterproof effect of the sealing block 7.

[0042] In one embodiment, tape 6 is butyl tape. As is known to those skilled in the art, butyl tape has high adhesion, aging resistance and low water vapor permeability, adapts to long-term outdoor temperature changes, avoids cracking of the adhesive layer, and effectively solves the defects of traditional silicone tape being prone to aging and PVC tape having insufficient adhesion, which will not be elaborated further here.

[0043] In one embodiment, the sealing block 7 is a foam sealing block made of closed-cell foam material, which combines elastic compression recovery and waterproofing. After being inserted into the tongue and groove joint 3, the foam sealing block can adapt to the deformation of the gap, so that the vertical ends of the sealing block abut against the respective ends of the two wall sandwich panels 2, eliminating the gap between the sealing block 7 and the wall sandwich panels 2. Moreover, the foam sealing block has minimal expansion and contraction under natural conditions, exhibiting excellent environmental adaptability.

[0044] In one embodiment, the fastener assembly 5 is fixed to the purlin 1 by a connecting piece. Specifically, refer to... Figure 2 The fastening strip assembly 5 includes a fastening strip body 501 and a fastening strip connecting member 503. The fastening strip body 501 includes a fastening strip embedding part embedded in the center seam 4 and side edge parts overlapping on both sides of the center seam 4. The fastening strip connecting member 503 connects the fastening strip embedding part to the purlin 1. Thus, the fastening strip body 501 and the purlin 1 are rigidly connected by the fastening strip connecting member 503, thereby enhancing the wind resistance and pressing the fastening strip body 501 against the wall sandwich panels 2 on both sides to prevent gaps and leakage. During installation, the fastening strip body 501 is first aligned and covered with the center seam 4, the side edge parts of the fastening strip body 501 are pressed against the edges of the wall sandwich panels 2 on both sides, and then the fastening strip connecting member 503 is used to connect the fastening strip body 501 to the purlin 1 for fixation.

[0045] In this embodiment, the fastener connecting member 503 can be a self-tapping screw that directly drills holes in the fastener body 501 and the purlin 1, or it can be a bolt assembly, etc., which is not limited in this application.

[0046] Furthermore, referring to Figure 2 The fastener assembly 5 also includes a snap-on cover 502. A snap-on groove is formed on the outer side of the fastener insert. The snap-on cover 502 is fastened into the snap-on groove and is used to cover the fastener connecting member 503 to prevent the fastener connecting member 503 from being corroded by moisture. Moreover, the snap-on cover 502 is detachable, which takes into account both the convenience of installation and the ease of maintenance.

[0047] In one embodiment, reference is made to... Figure 3 In the vertically spliced ​​first and second wall sandwich panels, the splicing portion of the first wall sandwich panel has a tenon 201, and the splicing portion of the second wall sandwich panel has a groove 202. The tenon 201 and the groove 202 form an interlocking fit. The outer side of the tenon 201 has a step, and a tongue and groove 3 is defined between the groove 202 and the step. With this design, the two wall sandwich panels 2 can be interlocked using mortise and tenon joints to achieve self-positioning of the vertical splicing, reducing installation deviation. At the same time, the tongue and groove 3 forms a cavity that facilitates water drainage and prevents capillary seepage.

[0048] Furthermore, referring to Figure 3 The wall system also includes a sandwich panel connector 203, such as a self-tapping screw, that connects and fixes the tenon 201 to the purlin 1. The groove 202 covers the sandwich panel connector 203. With this design, the sandwich panel connector 203 can be hidden between the two wall sandwich panels 2 to prevent exposure and corrosion. At the same time, the groove 202 can cover and protect the connection point while maintaining the water-guiding function of the tongue and groove joint 3.
