Description

Technical Field

[0001] This invention relates to the field of building wall technology, specifically to a waterproof structure and prefabricated wall assembly system. Background Technology

[0002] In modular prefabricated walls, related technologies often employ a light steel frame to bear its own weight and horizontal forces. The frame is filled with traditional insulation materials such as rock wool and glass wool, while the exterior consists of composite structural panels and a decorative surface layer, forming a non-load-bearing wall. The outer composite structural panels, decorative surface layer, and insulated frame are stacked and arranged parallel to each other. The outer edges of the panels and the corresponding door and window joints are typically flush and bonded with sealant. The inventors believe that with the ends of each panel perpendicular to its extension direction flush and only sealed with sealant, the sealant is prone to aging and peeling over long-term use, posing a risk of water seepage into the prefabricated wall structure. This results in low waterproofing performance and poor waterproofing effectiveness. Summary of the Invention

[0026] The technical solution provided by this invention has the following advantages:

[0027] 1. The waterproof structure provided by the present invention includes a bracket assembly and a sealing plate assembly. The bracket assembly includes a first bracket and a second bracket, either bracket being adapted to be built into a wall assembly. The first bracket and the second bracket are fixedly connected, and the outer end faces of the first bracket and the second bracket are offset from each other. The first bracket and the second bracket together form at least one semi-closed receiving groove. The sealing plate assembly is used to abut and seal the end face of either bracket. The sealing plate assembly has a bent portion, which is conformally arranged to the receiving groove.

[0028] The waterproof structure of this system uses a semi-enclosed receiving groove formed by the first and second supports in the support assembly. The sealing plate assembly abuts and seals the corresponding end face of the support assembly. The sealing plate assembly has a bent part that is correspondingly and conformally connected to the receiving groove. The sealing plate assembly resists external rainwater and other moisture to effectively prevent water from penetrating into the receiving groove and the support assembly. The receiving groove on the support assembly can create an uneven end face on the support assembly and facilitate the contact design between the bent part and the receiving groove on the support assembly, which is beneficial to improving the waterproof performance and waterproof effect of the wall assembly with the waterproof structure.

[0029] 2. The waterproof structure provided by the present invention, in the direction from the inner side to the outer side of the waterproof structure, the height of the first end face of the first bracket is greater than the height of the third end face of the second bracket; a first receiving groove is formed on the upper outer edge of the first bracket and the upper outer edge of the second bracket; in the direction from the inner side to the outer side of the waterproof structure, the height of the second end face of the first bracket is greater than the height of the fourth end face of the second bracket, and a second receiving groove is formed on the lower outer edge of the first bracket and the lower outer edge of the second bracket. By staggering the end faces of the first bracket and the second bracket in the height direction, a first receiving groove and a second receiving groove are formed on the upper outer edge and the lower outer edge of the bracket assembly, respectively. In the direction from the inner side to the outer side of the waterproof structure, the height of the first end face is greater than the height of the third end face, and the height of the second end face is greater than the height of the fourth end face. The receiving groove is set on the side of the waterproof structure close to the external wall. The sealing plate assembly is equipped with a bent portion to abut and close any receiving groove, thereby forming a waterproof structure with a lower outer side and a higher inner side on the upper outer edge and the lower outer edge of the bracket assembly. This facilitates the drainage of rainwater and other moisture to the external wall, thereby improving the waterproof performance.

[0030] 3. The waterproof structure provided by the present invention further includes a first grouting layer and a second grouting layer. The first grouting layer is filled and disposed within a first support; the first grouting layer is adapted to form a load-bearing structure; the second grouting layer is filled and disposed within a second support, and the second grouting layer is adapted to form a thermal insulation structure. By pouring and filling rigid concrete into the first support to solidify and connect the first support to form a load-bearing structure, the first grouting layer is disposed on the inner side of the waterproof structure. By pouring and filling thermal insulation grout into the second support to solidify and connect the second support to form a thermal insulation structure, the second grouting layer is disposed on the outer side of the waterproof structure, thereby enabling the wall assembly to have good load-bearing capacity and thermal insulation effect.

[0031] 4. The waterproof structure provided by this invention further includes a vacuum plate and a heat insulation plate. An installation space is provided between the first and second supports. Each support is configured as a rectangular frame structure. The vacuum plate extends along its height plane and is assembled within the installation space. Multiple heat insulation plates are configured, with adjacent heat insulation plates spaced apart. The heat insulation plates are fixedly connected to the support assembly, and each heat insulation plate is perpendicular to the extension surface of the vacuum plate. By isolating the heat transfer between the first and second supports along the extension surface of the vacuum plate parallel to the rectangular frame structure, and by isolating the heat transfer between the support assemblies along the extension surfaces perpendicular to the vacuum plate, cold bridges are avoided within the structure, which is beneficial for improving the thermal insulation effect of the wall assembly.

[0032] 5. A prefabricated wall assembly system, comprising a doorway wall assembly, a window wall assembly, and an open wall assembly, wherein each wall assembly is configured with a waterproof structure.

[0033] In this prefabricated wall assembly system, each wall assembly is equipped with a waterproof structure. The support components of the waterproof structure form a receiving groove, which is abutted against the sealing support components by the sealing plate components. The bending part and the receiving groove are in corresponding contact and matching. The sealing plate components are used to block external rainwater and other moisture, so as to effectively prevent water from penetrating into the wall assembly and give the wall assembly good waterproof performance.

[0057] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0058] Example 1

[0059] This embodiment provides a waterproof structure, including a support assembly and a sealing plate assembly. The sealing plate assembly blocks external rainwater and other moisture to effectively prevent water from penetrating into the support assembly. The support assembly encloses one or more semi-enclosed receiving grooves. The sealing plate assembly is used to abut against and seal the end face of the support assembly. The sealing plate assembly has a bent portion that is conformally arranged to the receiving groove.

[0060] In this embodiment, as Figure 1 and Figure 2As shown, the bracket assembly includes a first bracket 11 and a second bracket 12, each bracket being adapted to be embedded in the wall assembly; the end faces of the first bracket 11 and the second bracket 12 are staggered in the height direction; a receiving groove is provided on the side of the waterproof structure near the external wall surface; in the direction from the inner side to the outer side of the waterproof structure, the height of the first end face of the first bracket 11 is greater than the height of the third end face of the second bracket 12; the upper outer edge of the first bracket 11 and the upper outer edge of the second bracket 12 form a first receiving groove; the first end face is configured as the upper end face of the first bracket 11, and the third end face is configured as the upper end face of the second bracket 12. The sealing plate assembly includes a first sealing plate 21, the first sealing plate 21 being configured to abut against the first end face and the third end face respectively on its lateral end face facing the upper outer edge of the first bracket 11 and the upper outer edge of the second bracket 12 in its extending direction; the first sealing plate 21 has a first bent portion, the first bent portion being abutted within the first receiving groove.

[0061] like Figure 1 and Figure 2 As shown, in the direction from the inner side to the outer side of the waterproof structure, the height of the second end face of the first bracket 11 is greater than the height of the fourth end face of the second bracket 12. A second receiving groove is formed on the lower outer edge of the first bracket 11 and the lower outer edge of the second bracket 12. The second end face is configured as the lower end face of the first bracket 11, and the fourth end face is configured as the lower end face of the second bracket 12. The sealing plate assembly includes a second sealing plate 22, which is disposed in its extending direction with the lateral end faces of the lower outer edges of the first bracket 11 and the second bracket 12 respectively abutting against the second end face and the fourth end face; the second sealing plate 22 has a second bent portion, which abuts within the second receiving groove.

[0062] like Figure 1 and Figure 2 As shown, the upper and lower end faces of any bracket can be configured to be parallel to the horizontal plane, and the left and right end faces of any bracket can be configured to be parallel to the plane perpendicular to the horizontal plane. The bracket is configured as a keel structure. In this embodiment, the first bracket 11 and the second bracket 12 can adopt a galvanized light steel frame, which can be configured as a rectangular steel pipe or a cold-formed thin-walled steel section.

[0063] In some embodiments, when the first support 11 and the second support 12 can adopt a rectangular frame structure of the same size, the first support 11 and the second support 12 can be staggered vertically along the horizontal plane extension direction, with the first support 11 located at the high position of the structure and the second support 12 located at the low position of the structure, thereby forming the aforementioned first receiving groove and second receiving groove.

[0064] As a variation, the end faces of the first bracket 11 and the second bracket 12 are offset in the horizontal direction to form a receiving groove, and the sealing plate assembly is configured with a conformable sealing plate to abut and seal the receiving groove.

[0065] In this embodiment, as Figure 2 As shown, the first bracket 11 and the second bracket 12 are configured to be fixedly connected, and the first bracket 11 and the second bracket 12 are assembled into a whole by fasteners such as self-tapping screws or by welding.

[0066] like Figure 2 As shown, the sealing plate assembly also includes a side sealing plate 23, which extends along the height direction. The first sealing plate 21 and the second sealing plate 22 extend along the horizontal direction. The two ends of the side sealing plate 23 are fixedly abutted against the first sealing plate 21 and the second sealing plate 22, respectively.

[0067] like Figure 1 As shown, the waterproof structure also includes a panel assembly, which includes a first panel 31 and a second panel 32 arranged at intervals; any panel is fixedly connected to a support assembly; in the direction from the inside to the outside of the waterproof structure, the first panel 31, the first support 11, the second support 12 and the second panel 32 are stacked in sequence.

[0068] In one implementation, such as Figure 3 and Figure 4 As shown, the sealing plate assembly is configured to seal and wrap the outer edge end face of the bracket assembly. For example, the first sealing plate 21, the second sealing plate 22, and the two side sealing plates 23 wrap the upper and lower and left and right end faces of the first bracket 11 and the second bracket 12.

[0069] As a variation, the bracket assembly also includes a third bracket, which is disposed between the first panel 31 and the first bracket 11. The inner side of the third bracket is fixedly connected to the first panel 31, and the outer side of the third bracket is fixedly connected to the first bracket 11. The third bracket and the first bracket 11 are staggered along the horizontally extending surface. The height of the upper end face of the third bracket is greater than the height of the upper end face of the first bracket 11, forming a receiving groove with a higher inner side and a lower outer side at the upper outer edge of the third bracket and the first bracket 11. Furthermore, the height of the lower end face of the third bracket is greater than the height of the lower end face of the first bracket 11, forming another receiving groove with a higher inner side and a lower outer side at the lower outer edge of the third bracket and the first bracket 11.

[0070] As a variation, the support assembly also includes a fourth support, which is disposed between the second panel 32 and the second support 12. The inner side of the fourth support is fixedly connected to the second support 12, and the outer side of the fourth support is fixedly connected to the second panel 32. The fourth support and the second support 12 are staggered along the horizontally extending surface. The height of the upper end face of the second support 12 is greater than the height of the upper end face of the fourth support, forming a receiving groove with a higher inner side and a lower outer side at the upper outer edge of the second support 12 and the fourth support. Furthermore, the height of the lower end face of the second support 12 is greater than the height of the lower end face of the fourth support, forming another receiving groove with a higher inner side and a lower outer side at the lower outer edge of the second support 12 and the fourth support.

[0071] In this embodiment, the receiving groove is set on the side of the waterproof structure close to the external wall, and the sealing plate assembly is equipped with a bending part to abut and close any receiving groove, thereby forming a waterproof structure with a lower outer edge and a higher inner edge on the upper and lower outer edges of the bracket assembly, which is conducive to the discharge of rainwater and other moisture to the external wall, thereby improving the waterproof performance.

[0072] The waterproof structure provided in this embodiment forms a semi-enclosed first receiving groove located on the upper outer edge of the support assembly and a second receiving groove located on the lower outer edge of the support assembly by the first bracket 11 and the second bracket 12. The first sealing plate 21 and the second sealing plate 22 abut against the upper and lower end faces of the first bracket 11 and the second bracket 12 respectively for sealing. The first sealing plate 21 has a first bent portion, which connects to the first receiving groove, and the first receiving groove provides a supporting abutment surface. The second sealing plate 22 has a second bent portion, which connects to the second receiving groove, and the second receiving groove provides a connecting surface. Thus, the sealing plate assembly blocks external rainwater and other moisture, effectively preventing water from penetrating into the receiving groove and the support assembly. The receiving groove on the support assembly can create an uneven end face on the support assembly and facilitate the contact design between the bent portion and the receiving groove on the support assembly, which is beneficial to improving the waterproof performance and waterproof effect of the wall assembly with the waterproof structure.

[0073] In this embodiment, the first receiving groove can be configured as a stepped structure. The first receiving groove has a first groove surface and a second groove surface that are perpendicularly arranged. The first groove surface is a portion of the first support 11 abutting against the lateral end face facing the second support 12, exposing the connection between the first support 11 and the second support 12. The second groove surface is the upper end face of the second support 12. In some embodiments, the first groove surface and the second groove surface can be inclined to each other. The first groove surface is arranged along the height, and the second groove surface is inclined to the horizontal plane. The inclination angle can be set from 10 degrees to 80 degrees.

[0074] As a variation, the first receiving groove can be configured as a multi-layer stepped structure. The multi-layer stepped structure has a lower horizontal height along the direction from the inside to the outside of the waterproof structure to form a waterproof structure that is higher on the inside and lower on the outside, which facilitates the discharge of rainwater and other moisture to the outer wall surface.

[0075] In this embodiment, the receiving groove is configured as a stepped structure, and correspondingly, the bending portion is also configured as a stepped structure, such as... Figure 1 As shown, the first sealing plate 21 and the second sealing plate 22 adopt a Z-shaped stepped structure; the first sealing plate 21 and the second sealing plate 22 are made of non-metallic fiber insulation material. The first sealing plate 21 is fixed to the upper end of the bracket assembly by fasteners such as rivets, and the second sealing plate 22 is fixed to the lower end of the bracket assembly by fasteners such as rivets. The side sealing plates 23 can be made of non-metallic fiber insulation board, and the two side sealing plates 23 are fixed to the two sides of the bracket assembly by fasteners such as rivets.

[0076] In another embodiment, the receiving groove is configured as an inclined groove structure, and the bending portion is also configured as an inclined groove structure.

[0077] like Figure 1 As shown, the waterproof structure also includes a first grouting layer 15 and a second grouting layer 16. The first grouting layer 15 is filled and disposed within the first support 11; the first grouting layer 15 is adapted to form a load-bearing structure. The second grouting layer 16 is filled and disposed within the second support 12; the second grouting layer 16 is adapted to form a thermal insulation structure. By pouring and filling rigid concrete into the first support 11 to solidify and connect the first support 11 to form a load-bearing structure, the first grouting layer 15 is disposed on the inner side of the waterproof structure. By pouring and filling thermal insulation grout into the second support 12 to solidify and connect the second support 12 to form a thermal insulation structure, the second grouting layer 16 is disposed on the outer side of the waterproof structure, thereby giving the wall assembly good load-bearing capacity and thermal insulation effect.

[0078] In some embodiments, the first grouting layer 15 uses a lightweight concrete grout with a fire rating of Class A, a density of not less than 600 kg / m³, a compressive strength of not less than 2.0 MPa, and a thermal conductivity of not more than 0.14 W / (mK), while also serving as sound insulation, heat preservation, and structural support. The material is neutral to slightly alkaline to provide additional protection against corrosion.

[0079] In some embodiments, the second grouting layer 16 is made of lightweight concrete thermal insulation grout with a fire rating of Class A, a density of no more than 300 kg / m³, and a thermal conductivity of no more than 0.065 W / (mK), serving as a filler and auxiliary insulation agent; the material is neutral to slightly alkaline to provide additional protection for the structure's corrosion resistance.

[0080] like Figure 1 As shown, the waterproof structure also includes a vacuum plate 13 and a heat insulation plate 14. An installation space is provided between the first bracket 11 and the second bracket 12. Each bracket is configured as a rectangular frame structure. The vacuum plate 13 extends along its height plane and is assembled within the installation space. Multiple heat insulation plates 14 are provided, with adjacent heat insulation plates 14 spaced apart. The heat insulation plates 14 are fixedly connected to the bracket assembly, and each heat insulation plate 14 is perpendicular to the extension surface of the vacuum plate 13. Specifically, the heat insulation plates 14 are fixedly connected between the first bracket 11 and the second bracket 12. The vacuum plate 13 isolates heat transfer between the first bracket 11 and the second bracket 12 along its extension surface parallel to the rectangular frame structure, and the multiple heat insulation plates 14 isolate heat transfer between the bracket assemblies along their extension surfaces perpendicular to the vacuum plate 13. This effectively blocks internal and external heat conduction, preventing the formation of cold bridges within the structure, which is beneficial for improving the thermal insulation effect of the wall assembly. A gap is provided between the first bracket 11 and the second bracket 12 to form the aforementioned installation space. In this embodiment, the size of the gap is not specifically limited.

[0081] In some embodiments, the vacuum plate 13 is made of a material with a thermal conductivity of no more than 0.005 W / (mK), and the core material of the vacuum plate 13 is mainly composed of fumed silica. The vacuum plate 13 is protected with a surface inorganic coating.

[0082] The insulation board 14 can be made of non-metallic Class A flame-retardant fiber reinforced material, such as fiberglass or basalt. The insulation board 14 can be used to connect the first support 11 and the second support 12 to transfer the horizontal load within the structure and bear the self-weight of the external wall decoration layer, the second panel 32, the second grouting layer 16 and the second keel, so that the load is transferred to the first support 11.

[0083] The first panel 31 can be made of oriented strand board, profiled steel sheet, high-density calcium silicate board, or gypsum board. It can serve as the substrate for the interior decorative layer of the wall, the template for the first grouting layer 15, and also act as the wall structure skin. The second panel 32 can be made of oriented strand board, profiled steel sheet, or high-density calcium silicate board. It can serve as the substrate for the exterior decorative layer of the wall, the template for the second grouting layer 16, and also act as the wall structure skin.
