Description

Technical Field

[0001] This application relates to the field of building materials technology, and in particular to a waterproof exterior wall that is easy to install. Background Technology

[0002] In existing wall waterproofing structures, the compression sealing gasket method is commonly used for waterproofing. This involves placing a sealing gasket between two walls and then pressing the two walls together, allowing the sealing gasket to tightly fill the gap between the two walls under pressure, thus achieving a waterproofing effect.

[0003] In practical applications, the force on the wall is provided by the installation position of the wall. If the length of the wall plus the thickness of the sealing gasket is greater than the length of the installation position, the wall will compress the sealing gasket due to the force from the installation position after it is installed. This causes the sealing gasket to generate elastic force on the walls on both sides, achieving the effect of fixing and waterproofing. This structure is easy to install.

[0004] However, this connection method is unstable. When more than two walls need to be connected, each wall cannot be positioned relative to the others before installation is complete, which adds trouble to the installation process. At the same time, relying solely on the elasticity generated by the sealing gasket for fixation makes the wall unstable and affects its use. Therefore, it is necessary to provide a waterproof exterior wall with a stable connection method that is easy to install to solve the problem of unstable connection between walls.

[0046] A wall has a first surface and a second surface located on a side opposite to the first surface, the direction from the first surface to the second surface being denoted as the first direction;

[0047] The first connector has a first limiting step hole, and the axis of the first limiting step hole is set along the first direction;

[0052] The aforementioned easy-to-install waterproof exterior wall, by adding a fastener between two wall sections, provides additional constraint when the walls are connected, increasing the stability between the walls and thus solving the problem of weak connections between them.

[0053] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] Please see Figures 1-6This application provides an easy-to-install waterproof exterior wall 100, including a wall body 1, a first connector 2, a second connector 3, a fixing member 4, and a sealing gasket 5. The wall body 1 has a first surface 11a and a second surface 11b located on the side opposite to the first surface 11a, and the direction from the first surface 11a to the second surface 11b is denoted as the first direction. The first connector 2 has a first limiting step hole 21, and the axis of the first limiting step hole 21 is arranged along the first direction. The second connector 3 has a second limiting step hole 31, and the axis of the second limiting step hole 31 is arranged along the first direction. The fixing member 4 has a first positioning part 41 and a second positioning part 42 at both ends, respectively. The first positioning part 41 can be received in the first limiting step hole 21, and the second positioning part 42 can be received in the second limiting step hole 31. The sealing gasket 5 is disposed on the second connector 3 and located on the side of the second connector 3 away from the first connector 2. The first positioning part 41 of the fixing part 4 is fixed to the first limiting step hole 21 of the previous wall 1, and the second positioning part 42 of the fixing part 4 is fixed in the second limiting step hole 31 of the next wall 1, so as to fix the two adjacent walls 1.

[0055] Specifically, this is a fundamental component of the exterior wall system, having two surfaces, namely a first surface 11a and a second surface 11b, and a direction along a first direction. These walls 1 can be the exterior walls of a building, serving to provide isolation and protection for the building structure. First connector 2 and second connector 3 are elements for connecting the walls 1, each having a first limiting step hole 21 and a second limiting step hole 31. The axes of these holes are arranged along the first direction, allowing for the positioning of the fastener 4. The fastener 4 is an assembly for securing two adjacent walls 1. It includes a first positioning part 41 and a second positioning part 42, which connect to the first limiting step hole 21 and the second limiting step hole 31, respectively. This helps ensure a firm and stable connection between the two walls 1. A sealing gasket 5 is installed on the second connector 3, on the side away from the first connector 2. The sealing gasket 5 serves as a waterproof seal, effectively preventing moisture from penetrating to the connection point of the walls 1, thereby enhancing the waterproof performance of the entire system.

[0056] In one specific example, the first positioning part 41 has a first conical surface 411 and a second conical surface 412. The first conical surface 411 is disposed at the end of the first positioning part 41 away from the second positioning part 42, and the second conical surface 412 is disposed at the end of the first positioning part 41 close to the second positioning part 42.

[0057] The second positioning part 42 has a third conical surface 421 and a fourth conical surface 422. The third conical surface 421 is located at the end of the second positioning part 42 away from the first positioning part 41, and the fourth conical surface 422 is located at the end of the second positioning part 42 close to the first positioning part 41.

[0058] Specifically,

[0059] The first positioning part 41 has two different conical surfaces: a first conical surface 411 at one end and a second conical surface 412 at the other end. These conical surfaces provide precise positioning and alignment during installation, ensuring accurate connection between the wall components 1. The conical surface design ensures accurate positioning of the wall components 1, reducing installation errors and the need for adjustments. This helps simplify the installation process and improve system stability.

[0060] The second positioning part 42 also has two different conical surfaces, with a third conical surface 421 at one end and a fourth conical surface 422 at the other end. These conical surfaces function similarly to the first positioning part 41, providing precise positioning and alignment. The conical surface design of the second positioning part 42, combined with that of the first positioning part 41, ensures a stable and accurate connection between the walls 1. This helps simplify the installation process and reduces the need for maintenance and repair.

[0061] In one specific example, the fixing member 4 further includes a positioning rod portion 43, the two ends of which are fixedly connected to the first positioning portion 41 and the second positioning portion 42, respectively;

[0062] The angle between the first conical surface 411 and the axis of the positioning rod 43 is denoted as e, and e satisfies the relationship: 20°≤e≤30°;

[0063] The angle between the second conical surface 412 and the axis of the positioning rod 43 is denoted as f, and f satisfies the following relationship: 70°≥f≥50°;

[0064] The angle between the third conical surface 421 and the axis of the positioning rod 43 is denoted as g, and g satisfies the relationship: g≤30°;

[0065] The angle between the fourth conical surface 422 and the axis of the positioning rod 43 is denoted as h, and h satisfies the relationship: h≥50°.

[0066] Specifically, the positioning rod 43 is connected to the fixing member 4 and is used to enhance the connection between the walls 1. It provides additional support and stability, ensuring that the connection between the walls 1 will not loosen. Through the positioning rod 43, the connection between the walls 1 is more secure, reducing the impact of vibration and external pressure on the connection, and improving the stability and durability of the system. The relationship 20°≤e≤30° specifies the range of the included angle between the first conical surface 411 and the positioning rod 43, ensuring that the first conical surface 411 can be smoothly inserted into the first hole 211, and is also used for precise positioning of the wall 1 connection. The included angle between the second conical surface 412 and the axis of the positioning rod 43 is denoted as f, and f satisfies the relationship 70°≥f≥50°. The included angle range of the second conical surface 412 is related to the positioning rod 43 and is used to ensure the stability of the wall 1 connection. The setting of the included angle range ensures that the connection between the walls 1 is not easily loosened during installation, improving the reliability of the system. The angle between the third conical surface 421 and the axis of the positioning rod 43 is denoted as g, which satisfies the relationship: g ≤ 30°. By limiting the range of the angle, the stability and reliability of the connection can be ensured, and errors during installation can be reduced. The angle between the fourth conical surface 422 and the axis of the positioning rod 43 is denoted as h, which satisfies the relationship: h ≥ 50°. The range of the angle between the fourth conical surface 422 and the positioning rod 43 defines the angle between them, ensuring the firmness of the connection. Setting the range of the angle helps prevent the connection from loosening under external stress, improving the reliability and stability of the system.

[0067] In a specific example, the first stepped hole has a first hole 211 and a second hole 212, the first hole 211 and the second hole 212 are connected, and the radius a of the first hole 211 and the radius b of the second hole 212 have a relationship of a < b.

[0068] The second stepped hole has a third hole 311 and a fourth hole 312, and the radius c of the cross-sectional circle of the third hole 311 and the radius d of the cross-sectional circle of the fourth hole 312 have a relationship of c < d.

[0069] Specifically, the first stepped hole has a first hole 211 and a second hole 212, which are connected. The radius 'a' of the first hole 211 and the radius 'b' of the second hole 212 have a < b relationship. This feature describes the internal structure of the first stepped hole, which includes two holes with different radii. By setting holes with different radii, the connection of the wall 1 can be made easier during installation. The smaller hole is used for alignment and positioning, while the larger hole is used to accommodate the connector, increasing the reliability of the connection. The second stepped hole has a third hole 311 and a fourth hole 312, where the radius 'c' of the cross-sectional circle of the third hole 311 and the radius 'd' of the cross-sectional circle of the fourth hole 312 have a c < d relationship. This feature describes the internal structure of the second stepped hole, which includes two holes with different cross-sectional radii. The holes with different cross-sectional radii can be used to enhance the reliability of positioning and connection. The smaller hole is used for accurate positioning, while the larger hole is used to accommodate the fastener 4, thereby improving the stability of the connection.

[0070] In one specific example, one end of the first hole 211 is connected to the outside, and the other end is connected to the second hole 212;

[0071] One end of the third hole 311 is connected to the outside, and the other end is connected to the fourth hole 312;

[0072] The first positioning part 41 can abut against the inner wall of the second hole 212, and the second positioning part 42 can abut against the inner wall of the fourth hole 312.

[0073] Specifically, the first positioning part 41 is inserted into the first limiting step hole 21 from the end of the first hole 211 that connects to the outside, until the second conical surface 412 is completely inserted into the second hole 212. When the fixing member 4 is subjected to a force parallel to the first direction and pointing outward from the bottom of the first hole 211, the second conical surface 412 will abut against the bottom surface of the second hole 212, thereby preventing the first positioning part 41 from sliding out of the first limiting step hole 21. The second positioning part 42 is inserted into the second limiting step hole 31 from the side of the third hole 311 that connects to the outside. When the fixing member 4 is subjected to a force parallel to the first direction and pointing outward from the bottom of the third hole 311, the fourth conical surface 422 will abut against the bottom surface of the fourth hole 312, thereby preventing the second positioning part 42 from sliding out of the second limiting step hole 31.

[0074] In one specific example, the first connector 2 is provided with a positioning protrusion 22, the length direction of which is arranged along the first direction;

[0075] The second connector 3 has a positioning groove 32, and the positioning protrusion 22 of the preceding wall 1 can be received in the positioning groove 32 of the following wall 1 and fit against the inner wall of the positioning groove 32.

[0076] Specifically, the first connector 2 is provided with a positioning protrusion 22, the length direction of which is arranged along the first direction. The main function of this feature is to provide positioning and orientation for the fastener 4. The positioning protrusion 22, in conjunction with the positioning groove 32, ensures accurate positioning of the connection. By providing the positioning protrusion 22 on the first connector 2, the stability and accuracy of the connection can be ensured. It helps reduce incorrect assembly and improves the efficiency and accuracy of installation. The second connector 3 is provided with a positioning groove 32. The positioning protrusion 22 of the preceding wall 1 can be received within the positioning groove 32 of the following wall 1 and fit against the inner wall of the positioning groove 32. This feature is used to receive and fix the positioning protrusion 22, ensuring a firm and accurate connection between the two adjacent walls 1. When the positioning protrusion 22 is inserted into the positioning groove 32, it makes close contact with the inner wall of the groove, providing additional stability. By using the combination of the positioning protrusion 22 and the positioning groove 32, accurate positioning and fixation between the two adjacent walls 1 are ensured. This can improve the stability and strength of the wall system and reduce displacement caused by external factors (such as wind and vibration).

[0077] In a specific example, the first connector 2 is provided with a first boss 23, and the first limiting step hole 21 is formed on the first boss 23;

[0078] The second connector 3 has a first groove 33, and the second limiting step hole 31 is formed in the first groove 33;

[0079] The positioning protrusions 22 are arranged in two rows, and the two rows of positioning protrusions 22 are respectively provided on both sides of the first boss 23. The positioning grooves 32 are arranged in two rows, and the two rows of positioning grooves 32 are respectively provided on both sides of the first groove 33.

[0080] The first boss 23 is connected to the first groove 33 on the previous wall 1 via a keyway.

[0081] Specifically, the first connector 2 is provided with a first boss 23, and a first limiting step hole 21 is formed on the first boss 23. The first boss 23 is used to receive and support the first positioning part 41, ensuring the stable positioning of the fastener 4. The combination of the first limiting step hole 21 and the first boss 23 can achieve reliable fixation. This ensures that the fastener 4 has accurate positioning and stability in the connection between the walls 1. The first boss 23 provides solid support, which helps to maintain the verticality and positional consistency of the walls 1. The second connector 3 is provided with a first groove 33, and a second limiting step hole 31 is formed in the first groove 33. The first groove 33 is used to receive and position the first positioning part 41, ensuring the stable position of the fastener 4. The combination of the second limiting step hole 31 and the first groove 33 realizes the reliability of the connection. This ensures that the fastener 4 has accurate positioning and stability in the connection between the walls 1. The first groove 33 provides additional support, helping to maintain the verticality and positional consistency of the walls 1. The positioning protrusions 22 are arranged in two rows, respectively on both sides of the first boss 23. The positioning grooves 32 are also arranged in two rows, respectively on both sides of the first groove 33. These multiple rows of positioning protrusions 22 and positioning grooves 32 ensure a stronger and more stable connection between the wall components 1. They provide additional support and positioning functions. The multiple rows of positioning protrusions 22 and positioning grooves 32 help to distribute forces during the connection, improving its stability. They also provide a larger connection area, helping to resist external stresses.

[0082] In a specific example, a second protrusion 12 is provided on the first surface 11a, and a third protrusion 13 is provided on the second surface 11b. A second groove 24 is provided on the first connector 2, and a third groove 34 is provided on the second connector 3. The second protrusion 12 can be received in the second groove 24, and the third protrusion 13 can be received in the third groove 34.

[0083] Specifically, a second boss 12 is provided on the first surface 11a, and a third boss 13 is provided on the second surface 11b. The second boss 12 and the third boss 13 provide an additional connection point for supporting and fixing the wall 1. These bosses enhance the stability and connection strength of the wall 1. They provide additional support between the two walls 1, helping to reduce the impact of external stress on the wall 1. A second groove 24 is provided on the first connector 2, and a third groove 34 is provided on the second connector 3. The second groove 24 and the third groove 34 are provided to accommodate the second boss 12 and the third boss 13, ensuring that they can be firmly positioned during the connection process. These grooves help ensure the stable positioning of the bosses, providing a reliable way to connect the wall 1. They reduce uncertainty during installation and ensure the accuracy of the connection.

[0084] In a specific example, let the thickness of the gasket 5 be i, the depth of the first hole 211 be j, the depth of the third hole 311 be k, and the length of the positioning rod portion 43 be n, satisfying the relational expression: j + k < n ≤ j + k + i.

[0085] Specifically, the gasket 5 is usually used to create a waterproof isolation layer to prevent moisture from penetrating into the interior of the wall 1. The thickness of the gasket 5 refers to the thickness of the cushion layer of the sealing layer. Appropriately selecting and configuring the thickness of the gasket 5 can ensure the waterproof effect and enhance the waterproof performance of the system. A thicker gasket 5 generally provides better watertightness. The first hole 211 is a key component in the connection system, and the depth refers to the vertical distance of the hole. Controlling the depth of the first hole 211 can affect the insertion depth of the connecting member and the connection between the wall 1. The correct setting of the depth helps to ensure the firmness and reliability of the connection. The third hole 311 is also a key component of the connection system, and the depth refers to the vertical distance of the hole. Appropriately setting the depth of the third hole 311 is crucial for ensuring the stability and reliability of the connection system. Its depth, together with the depths of other holes, determines the accurate positioning of the connecting member. The positioning rod portion 43 is an element for connecting the fixture 4, and its length determines the relative position between the fixtures 4. The length of the positioning rod portion 43 affects the alignment and connection of the fixtures 4, ensuring the correct spacing between the walls 1. An appropriate length can enhance the stability of the connection. The relational expression j + k < n ≤ j + k + i reflects the relationship between various parameters, requiring the length (n) of the positioning rod portion 43 to be within an appropriate range to maintain the stability of the waterproof exterior wall system, the reliability of the connection, and the waterproof performance.

[0086] In a specific example, both the first connecting member 2 and the second connecting member 3 are bolted to the wall 1.

[0087] Specifically, this feature relates to the function of bolting the first connecting member 2 and the second connecting member 3 of the waterproof exterior wall to the wall 1. This connection method has the following functions and beneficial effects. By using bolt connection, the first connecting member 2 and the second connecting member 3 can be firmly fixed to the wall 1, thereby providing the stability of the entire waterproof exterior wall system. This is crucial for maintaining the stability of the connection of the wall 1 under various environmental conditions, especially under external pressure or vibration. Bolt connection usually provides a reliable connection method and can maintain the integrity of the waterproof exterior wall for a long time. This ensures that the system is not easily loosened or damaged by external forces. Bolt connection is usually easy to install and maintain. This helps to quickly install the waterproof exterior wall and reduces the construction period of the building project. Bolt connection is applicable to various types of walls 1, including walls 1 with different materials and structures. This provides greater flexibility to meet the needs of different projects.

[0088] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
