Description

Technical Field

[0001] This utility model relates to the field of building envelope technology, and in particular to an exterior wall panel. Background Technology

[0002] Exterior wall panels are a type of paneling that is laid on the outside of building walls and has functions such as sound insulation, waterproofing, fireproofing, heat insulation, or decoration.

[0003] Patent document CN 100526254 C discloses a lightweight waterproof wall panel made of waterproof material. One end of the panel has a groove, and the other end has a protrusion. Multiple panels are connected by embedding the protrusion into the groove. When rainwater or other liquids flow onto the lightweight waterproof wall panel, they run down the surface and are less likely to seep into the other side of the panel, thus preventing liquid from entering the interior through the building walls.

[0004] However, since the surface of the wall panel is not perfectly smooth, when liquid flows on the surface of the wall panel, it will form meandering flow lines, which will cause the liquid to stay on the wall panel for a long time and increase the risk of it entering the other side of the wall panel through the joints. Utility Model Content

[0005] The purpose of this utility model is to provide an exterior wall panel that allows liquid flowing onto the surface of the panel to flow away in a timely manner, preventing it from flowing from the joint gaps to the other side of the panel.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Exterior wall panels, including:

[0008] The body has a first end and a second end opposite to each other, as well as a third end and a fourth end opposite to each other. The first end is provided with a protrusion, and the second end is provided with a groove. The protrusion of one body can be inserted into the groove of the other body.

[0009] A drainage groove is provided on the plate surface of the main body. The drainage groove extends in a straight line on the plate surface of the main body and extends to the end faces of the third end and the fourth end.

[0010] Optionally, the angle between the wall and the bottom of the drainage trough is an obtuse angle.

[0011] Optionally, the body is provided with fastening holes, and a fastener is inserted into both the fastening holes on one body and the fastening holes on another body.

[0012] Optionally, it may also include a reinforcing layer, which is laid on the surface of the body.

[0013] Optionally, it also includes a thermal insulation layer, the body has a hollow structure, the body has an opening that communicates with the inner cavity of the body, and the thermal insulation layer is disposed inside the inner cavity of the body.

[0014] Optionally, the insulation layer is made of a two-component foaming agent.

[0015] Optionally, it also includes a sealing element for closing the opening on the body.

[0016] Optionally, the body is provided with a support portion, which is located inside the cavity of the body and is respectively connected to the inner walls of two plates of the body.

[0017] Optionally, it also includes an edge-trimming body, one end of which has a flat end face, and the opposite end is provided with the protrusion or the groove.

[0018] Optionally, it also includes a connector, through which the edge-finishing body and the exterior wall surface are connected.

[0019] The beneficial effects of this utility model are:

[0020] The exterior wall panel provided by this utility model includes a main body. When a protrusion of one main body is inserted into a groove of another main body, the two main bodies are connected. A drainage groove is provided on the surface of the main body. When rainwater or other liquids flow onto the surface of the main body, they collect in the drainage groove. Because the drainage groove extends in a straight line on the surface of the panel, reaching the end faces of the third and fourth ends, the liquid collected in the drainage groove flows away along the length of the drainage groove, preventing it from lingering on the surface of the main body and avoiding it from flowing to the other side of the main body through the connection gap between the two main bodies, thus affecting the waterproofing effect of the wall panel.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1-3 As shown, this embodiment provides an exterior wall panel for installation on the exterior of a building wall. The exterior wall panel includes a body 1, which has opposing first and second ends, as well as opposing third and fourth ends. The first end has a protrusion 13, and the second end has a groove 14. The protrusion 13 of one body 1 can be inserted into the groove 14 of another body 1, thereby achieving a quick and convenient connection between the two bodies 1. A drainage channel 15 is provided on the surface of the body 1, extending in a straight line to the end faces of the third and fourth ends. When rainwater or other liquids flow onto the surface of the body 1, they collect in the drainage channel 15 and flow along the length of the drainage channel 15.

[0038] When the protrusion 13 of one body 1 is inserted into the groove 14 of another body 1, the two bodies 1 are connected. A drainage groove 15 is provided on the surface of the body 1. When rainwater or other liquids flow onto the surface of the body 1, they will collect in the drainage groove 15. Since the drainage groove 15 extends in a straight line on the surface of the body 1 and extends to the end faces of the third and fourth ends, the liquid collected in the drainage groove 15 will flow away along the length of the drainage groove 15 and will not stay on the surface of the body 1 for too long. This prevents it from flowing to the other side of the body 1 through the connection gap between the two bodies 1, thereby affecting the waterproof effect of the wall panel.

[0039] In this embodiment, the surface of the body 1 is rectangular, and the drainage channel 15 extends along the length of the body 1. When the exterior wall panel is laid on the building wall, the length of the body 1 is vertical, thereby accelerating the flow of liquid collected in the drainage channel 15. Exemplarily, multiple drainage channels 15 are provided.

[0040] Furthermore, the angle between the wall and the bottom of the drainage trough 15 is an obtuse angle, which facilitates the collection of liquid on the plate surface.

[0041] Furthermore, the main body 1 is made of antibacterial high-strength aluminum alloy, which has high strength and good environmental performance.

[0042] In this embodiment, both the protrusion 13 and the groove 14 are of the same length as the body 1, so that the two bodies 1 are tightly connected. For example, sealant can also be applied to the side wall of the protrusion 13 and the groove wall of the groove 14, so that the protrusion 13 is firmly connected after being inserted into the groove 14.

[0043] Furthermore, such as Figure 1 As shown, a fastening hole 12 is provided on the body 1. A fastener is inserted into the fastening hole 12 on one body 1 and the fastening hole 12 on the other body 1, thereby strengthening the connection between the two bodies 1. In this embodiment, the fastening hole 12 is provided on the groove wall of the groove 14 and the side wall of the protrusion 13. Exemplarily, the fastener includes a bolt.

[0044] Furthermore, the exterior wall panel also includes a reinforcing layer, which is laid on the surface of the main body 1 to increase the strength of the main body 1 and extend its service life. At the same time, the reinforcing layer can also improve the appearance of the main body 1 and serve a decorative purpose. In this embodiment, the reinforcing layer can be obtained by spraying real stone paint, or by roller coating / heat transfer printing and other processes.

[0045] Furthermore, such as Figure 1 As shown, the exterior wall panel also includes an insulation layer 3. The main body 1 has a hollow structure with an opening that connects to the inner cavity of the main body 1. The insulation layer 3 is disposed within the inner cavity of the main body 1, enabling the exterior wall panel to simultaneously provide insulation and reduce heat loss from the room. In this embodiment, the insulation layer 3 fills the entire inner cavity of the main body 1, resulting in good insulation performance. For example, the opening is located at the third end of the main body 1.

[0046] Specifically, the insulation layer 3 is made of a two-component foaming agent, which is a foaming agent composed of two components and has the effects of being soft, waterproof, heat-insulating, and flame-retardant.

[0047] Furthermore, the exterior wall panel also includes a sealing element, which is used to seal the opening on the main body 1. After the insulation layer 3 is filled, the sealing element is used to seal the opening to prevent water from entering the insulation layer 3. In this embodiment, the sealing element is made of antibacterial high-strength aluminum alloy, which has high strength and good environmental performance.

[0048] Furthermore, such as Figure 1 and Figure 2 As shown, a support portion 11 is provided on the main body 1. The support portion 11 is located inside the cavity of the main body 1 and is connected to the inner walls of the two plates of the main body 1 respectively, which increases the strength of the main body 1 and prevents the surface of the main body 1 from collapsing. In this embodiment, the support portion 11 is plate-shaped, and one end of the support portion 11 is supported at the bottom of the drainage groove 15.

[0049] Furthermore, such as Figure 4 As shown, the exterior wall panel also includes an edge trimming body 2. One end of the edge trimming body 2 is flat, and the other end is provided with a protrusion 13 or a groove 14, so that the outer edge of the edge trimming body 2 after being connected to the body 1 is flat and can better fit the shape of the exterior wall surface. The other structures of the edge trimming body 2 in this embodiment are the same as those of the body 1.

[0050] Furthermore, the exterior wall panel also includes a connector 4, which connects the edge trim body 2 to the exterior wall surface. For example... Figures 5-10 As shown, this embodiment provides six forms of connector 4. Figure 5 and Figure 6 Connector 4 is suitable for connecting the edge trim body 2 to the flat exterior wall surface. Figures 7-10 The connector 4 is suitable for connecting the edge trim body 2 to the corner of the exterior wall. Further, the edge trim body 2 is clamped on the connector 4, and the connector 4 and the exterior wall surface are connected by expansion bolts or ordinary screws. For example, the connector 4 can clamp the edge trim body 2 with a thickness of about 30mm.

[0051] The processing and installation process of the exterior wall panels provided in this embodiment is roughly as follows:

[0052] The first step is to obtain the body 1 using an extrusion process; the second step is to fill the inner cavity of the body 1 with the insulation layer 3 through the opening and seal the opening with a sealing piece; the third step is to spray a reinforcing layer on the surface of the body 1; the fourth step is to insert the protrusion 13 on one body 1 into the groove 14 on another body 1 and connect multiple bodies 1 by using fasteners through the fastening holes 12 on the two bodies 1; the fifth step is to connect the body 1 with the edge trimming body 2 and install the edge trimming body 2 on the exterior wall surface using a connector 4.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
