Description

Technical Field

[0001] This application relates to the field of building exterior wall insulation construction technology, and in particular to a waterproof structure and construction method for an integrated exterior wall insulation and decoration panel. Background Technology

[0002] External wall insulation has become one of the main methods for achieving building energy conservation, leading to the widespread adoption of integrated insulation and decorative panels. These panels are a new type of building material that combines decoration, energy saving, insulation, fire resistance, waterproofing, and environmental protection. They consist of a decorative layer and an insulation substrate. The decorative layer can be made of fluorocarbon coatings, stone-like paint, ceramic thin plates, etc., depending on the specific needs. They offer advantages such as thermal insulation, energy saving, waterproofing, moisture resistance, strong corrosion resistance, environmental friendliness, economy, durability, light weight, and excellent decorative effect.

[0003] Currently, integrated thermal insulation and decorative panels are primarily installed onto the exterior wall substrate using L-shaped support fasteners. The joints between the panels are sealed with sealant to prevent water seepage.

[0004] Gaps may appear in the sealant during caulking, and the sealant will also age over time, causing gaps to appear at the joints of the insulation and decorative panels, resulting in poor water resistance of the integrated insulation and decorative panels. Summary of the Invention

[0005] To improve the water-proofing effect of integrated thermal insulation and decorative panels, this application provides a water-proofing structure and construction method for integrated thermal insulation and decorative panels for exterior walls.

[0006] On the one hand, the waterproof structure of the integrated exterior wall insulation and decoration panel provided in this application adopts the following technical solution:

[0007] A waterproof structure for an integrated exterior wall insulation and decoration panel includes horizontal mounting plates, vertical mounting plates, and sealing strips. Multiple horizontal mounting plates are pre-embedded at horizontal intervals on the exterior wall. Each horizontal mounting plate has a T-shaped cross-section. The vertical section of the horizontal mounting plate is flush with the exterior wall, while the horizontal section extends away from the exterior wall. A water-blocking block with a right-angled trapezoidal cross-section is provided on the upper surface of the horizontal section, with its lowest inclined end away from the exterior wall. A water-blocking plate is provided on the lower surface of the horizontal section, away from the exterior wall. A first sealing groove is formed at the top of the water-blocking block, and a second sealing groove is formed on the lower surface of the horizontal section. The vertical mounting plate is formed by connecting a web perpendicular to the exterior wall and a wing plate parallel to the exterior wall. The vertical mounting plate is vertically snapped between two adjacent horizontal mounting plates. A third sealing groove is formed on the web of the vertical mounting plate. The first, second, and third sealing grooves are interconnected, and each contains the sealing strip.

[0008] Preferably, the lower end of the water baffle is inclined, and the lower end of the water baffle is far from the outer wall.

[0009] Preferably, the water-blocking block is hollow.

[0010] Preferably, the inner side of the wing plate has multiple water guide grooves along the vertical direction.

[0011] Preferably, the bottom of the wing plate is attached to the inclined side of the water-blocking block.

[0012] Preferably, adhesive grooves are provided on both sides of the web and on both sides of the vertical section.

[0013] Preferably, both the water-blocking block and the water-blocking plate have notches for accommodating the vertical mounting plate, the vertical section has a card interface for inserting the web plate, and the vertical section is also provided with a fixing component for fixing the web plate inserted into the vertical section.

[0014] Preferably, sealant is applied between the upper and lower ends of the web and the horizontal section.

[0015] Preferably, the fixing component includes a spring and a steel ball. Fixing grooves with inclined bottom walls are provided on both sides of the card interface. The fixing grooves are deeper on the side closer to the outer wall and shallower on the side farther away from the outer wall. The first spring and the steel ball are both located in the fixing grooves. One end of the spring is connected to the vertical section and the other end is connected to the steel ball, so that the steel ball always has a tendency to move away from the outer wall.

[0016] On the other hand, this application provides a construction method for an integrated exterior wall insulation and decoration panel, including the following steps:

[0017] S1: Prefabricate horizontal and vertical mounting plates according to design requirements, and prefabricate matching base plates, and groove the base plates on both sides according to design requirements; S2: During exterior wall construction, embed multiple horizontal mounting plates into the exterior wall at intervals according to design requirements; S3: Install the base plate between two adjacent horizontal mounting plates; S4: Install the vertical mounting plate between two horizontal mounting plates and where it is in contact with the vertical side of the base plate.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. The sloped design of the water-blocking plate and water-blocking block prevents rainwater from penetrating the exterior wall against gravity along the horizontally installed plate during rainy weather, thus forming the first layer of waterproof structure.

[0020] 2. The substrate is snapped into place within the rectangular space enclosed by two adjacent horizontal mounting plates and two adjacent vertical mounting plates. At this time, the sealing strips in the first sealing groove, the second sealing groove, and the third sealing groove are also connected and bonded together in sequence, so that the substrate has a good anti-permeability effect on all sides. The sealing strips form a second layer of anti-water seepage structure on all sides.

[0021] 3. The web of the vertical mounting plate has adhesive grooves on both sides along the vertical direction. The vertical section of the horizontal mounting plate also has adhesive grooves on both sides along the length of the horizontal mounting plate. Silicone sealant is applied to the adhesive grooves. The silicone sealant forms a third waterproof structure between the horizontal mounting plate, the vertical mounting plate and the substrate. The three-layer waterproof structure provides a good waterproof effect. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a waterproof structure for an integrated exterior wall insulation and decoration panel, referring to... Figures 1-3The waterproof structure of the integrated exterior wall insulation and decoration panel includes a horizontal mounting plate 1, a vertical mounting plate 2, and a sealing strip 3. Multiple horizontal mounting plates 1 are pre-embedded at equal intervals along the horizontal direction on the exterior wall according to design requirements. The cross-sectional shape of the horizontal mounting plate 1 is T-shaped. The vertical section 11 of the horizontal mounting plate 1 is flush with the exterior wall, and the horizontal section 12 of the horizontal mounting plate 1 is located in the middle of the vertical section 11 and extends away from the exterior wall. Embedded reinforcing bars are installed on the side of the vertical section 11 facing the exterior wall, and these reinforcing bars are embedded in the exterior wall during construction. The cross-sectional shape of the vertical mounting plate 2 is also T-shaped. The vertical mounting plate 2 is composed of a web plate 21 perpendicular to the exterior wall and a wing plate 22 parallel to the exterior wall. The vertical mounting plate 2 is vertically snapped between two adjacent horizontal mounting plates 1, supporting the two adjacent insulation board substrates on the left and right sides and filling the gap between the two substrates. The substrate is located within the rectangular space enclosed by two adjacent vertical mounting plates 2 and two adjacent horizontal mounting plates 1. When installed in place, the outer side of the substrate is flush with the outer side of the wing plate 22 and the outer side of the horizontal section 12.

[0031] Reference Figure 2 and Figure 3 A water-blocking block 13 with a right-angled trapezoidal cross-section is provided on the upper surface of the horizontal section 12. The lower base of the water-blocking block 13 is fixedly connected to the horizontal section 12, and the lowest inclined end of the water-blocking block 13 is away from the outer wall. The water-blocking block 13 is made of aluminum alloy and is hollow to reduce the overall structural weight. Diagonal braces for reinforcement are provided inside the water-blocking block 13 to improve the overall structural strength. A water-blocking plate 14 is provided on the lower surface of the horizontal section 12 away from the outer wall. The water-blocking plate 14 is a rectangular long plate, and its outer side is flush with the outer side of the horizontal section 12. When the thermal insulation decorative panel substrate is installed on the outer wall, the upper end of the substrate is clamped to the upper horizontal mounting plate 1 by the water-blocking plate 14, and the lower end of the substrate is clamped to the lower horizontal mounting plate 1 by the water-blocking block 13, thereby fixing the substrate. Simultaneously, combined with... Figure 1 A vertical mounting plate 2 is installed between two horizontally adjacent base plates, fixing the left and right sides of the base plates. The lower end of the water-blocking plate 14 is inclined, and the distance between the lower end of the water-blocking plate 14 and the outer wall is large, while the distance between the upper end of the water-blocking plate 14 and the outer wall is small. During rainy weather, rainwater flows downward along the base plates. At this time, under the action of the inclined surface of the water-blocking block 13, the rainwater cannot move towards the outer wall along the upper surface of the horizontal mounting plate 1; at the same time, the inclined surface of the lower end of the water-blocking plate 14 also prevents rainwater from penetrating towards the outer wall against gravity; therefore, the water-blocking plate 14 and the inclined surface of the water-blocking block 13 form the first layer of waterproof structure.

[0032] Reference Figure 2 and Figure 3A first sealing groove 131 is formed at the top of the water-blocking block 13 along its length. A sealing strip 3, made of polyethylene foam, is installed in the first sealing groove 131. The polyethylene foam can deform to a certain extent while effectively preventing water penetration and avoiding rainwater seeping into the inner side of the substrate. A second sealing groove 121 for accommodating the sealing strip 3 is formed on the lower surface of the horizontal section 12. The second sealing groove 121 is vertically opposite to the first sealing groove 131. A third sealing groove 211 for accommodating the sealing strip 3 is formed on both sides of the web 21 of the vertical mounting plate 2 along its length. The first sealing groove 131, the second sealing groove 121, and the third sealing groove 211 are connected and each contains a sealing strip 3.

[0033] During substrate installation, sealing strips 3 are glued and installed in the first sealing groove 131, the second sealing groove 121, and the third sealing groove 211, and glue is applied to the ends of the sealing strips 3. The substrate is snapped into place within the rectangular space enclosed by two adjacent horizontal mounting plates 1 and two adjacent vertical mounting plates 2. At this time, the sealing strips 3 in the first sealing groove 131, the second sealing groove 121, and the third sealing groove 211 are also connected and glued together in sequence. The sealing strips 3 are provided on all four edges of the substrate, so that the substrate has a good anti-permeability effect on all four sides. The sealing strips 3 form a second layer of waterproof structure.

[0034] Reference Figure 3 Multiple water guide grooves 23 are vertically formed on the inner side of the wing plate 22 of the vertical mounting plate 2. Combined with... Figure 2 and Figure 4 The bottom of the wing plate 22 is also inclined, and the bottom of the wing plate 22 is in contact with the inclined side of the water-blocking block 13. When rainwater seeps into the space between the base plate and the wing plate 22, the water guide channel 23 prevents the rainwater from continuing to seep into the inside of the vertical mounting plate 2. The seeping water will collect at the water guide channel 23 and flow downward along the water guide channel 23 until it flows to the inclined surface of the water-blocking block 13, and then is discharged along the inclined surface of the water-blocking block 13.

[0035] Reference Figure 2 and Figure 3On both sides of the web 21 of the vertical mounting plate 2, adhesive application grooves 4 are formed along the vertical direction. On both sides of the vertical section 11 of the horizontal mounting plate 1, adhesive application grooves 4 are also formed along the length of the horizontal mounting plate 1. During substrate installation, silicone sealant is applied to the adhesive application grooves 4. The adhesive application grooves 4 can hold more sealant and increase the contact area, resulting in better adhesion between the horizontal mounting plate 1, the vertical mounting plate 2, and the substrate. The silicone sealant forms a third waterproof layer between the horizontal mounting plate 1, the vertical mounting plate 2, and the substrate, further improving waterproof performance. Simultaneously, the bonding location is on the side of the substrate closest to the wall. Compared to traditional caulking processes, the sealant does not directly contact external moisture or sunlight, extending its service life and slowing down its aging.

[0036] Reference Figure 4 and Figure 5 Both the water-blocking block 13 and the water-blocking plate 14 have notches for accommodating the vertical mounting plate 2. The vertical section 11 of the horizontal mounting plate 1 has a locking interface 111 for inserting the web plate 21. A fixing component is also provided on the vertical section 11 to fix the web plate 21 inserted into the vertical section 11. Sealant is applied between the upper and lower ends of the web plate 21 and the horizontal mounting plate 1, so that when the vertical mounting plate 2 is inserted into the horizontal mounting plate 1, the sealant seals the gap between the vertical mounting plate 2 and the horizontal mounting plate 1, further improving the water-proof effect.

[0037] Reference Figure 5 The fixing component includes a spring 51 and a steel ball 52. Fixing grooves 112 with inclined bottom walls are provided on both sides of the vertical section 11 and the card interface 111. The fixing groove 112 is deeper on the side closer to the outer wall and shallower on the side farther away from the outer wall. The first spring 51 and the steel ball 52 are both located in the fixing groove 112. The diameter of the steel ball 52 is smaller than the deepest point of the fixing groove 112 but larger than the shallowest point of the fixing groove 112. One end of the spring 51 is connected to the vertical section 11 and the other end is connected to the steel ball 52. The spring 51 makes the steel ball 52 always have a tendency to move away from the outer wall.

[0038] When the vertical mounting plate 2 is inserted into the horizontal mounting plate 1, the web plate 21 pushes the steel ball 52 towards the outer wall. At this time, the gap between the steel ball 52 and the bottom wall of the fixing groove 112 and the web plate 21 tends to increase, and the vertical mounting plate 2 can be smoothly inserted into the locking interface 111. After the vertical mounting plate 2 is inserted into place, the steel ball 52, under the action of the spring 51, is in contact with the bottom wall of the locking interface 111 on one side and with the web plate 21 on the other side. Thus, when the vertical mounting plate 2 tends to move away from the outer wall, the web plate 21 tends to drive the steel ball 52 to move away from the outer wall. At this time, the steel ball 52 clamps and fixes the vertical mounting plate 2 onto the horizontal mounting plate 1.

[0039] The implementation principle of the waterproof structure of the integrated exterior wall insulation and decoration panel in this application embodiment is as follows: The inclined surfaces of the water-blocking plate 14 and the water-blocking block 13 prevent rainwater from penetrating the exterior wall against gravity along the horizontal mounting plate 1 during rainy weather, thus forming the first layer of waterproof structure. The base plate is snapped into place within the rectangular space enclosed by two adjacent horizontal mounting plates 1 and two adjacent vertical mounting plates 2. At this time, the sealing strips 3 in the first sealing groove 131, the second sealing groove 121, and the third sealing groove 211 are also sequentially connected and adhered to one side. This design ensures good impermeability around the substrate, with the sealing strip 3 forming a second layer of waterproof structure around the perimeter. The web 21 of the vertical mounting plate 2 has adhesive grooves 4 on both sides along the vertical direction, and the vertical section 11 of the horizontal mounting plate 1 also has adhesive grooves 4 on both sides along the length of the horizontal mounting plate 1. Silicone sealant is applied to the adhesive grooves 4, forming a third layer of waterproof structure between the horizontal mounting plate 1, the vertical mounting plate 2, and the substrate. This three-layer waterproof structure provides excellent waterproofing.

At the same time, prefabricate base plates that are compatible with horizontal mounting plate 1 and vertical mounting plate 2, and open corresponding grooves on the upper and lower sides of the base plates.

[0042] S2: During the construction of the exterior wall, the pre-embedded steel bars of the horizontal installation plate 1 are built into the exterior wall, and the spacing of multiple horizontal installation plates 1 is selected according to the design requirements.

[0043] S3: A sealing strip 3 is bonded to the first sealing groove 131 on the water-blocking block 13, the second sealing groove 121 on the lower surface of the horizontal section 12, and the third sealing groove 211 on the web plate 21, and adhesive is applied to the end of the sealing strip 3.
