Description

Technical Field

[0001] This utility model relates to the field of building materials technology, and in particular to an external wall protection panel with drainage function and an external wall insulation system. Background Technology

[0002] During the construction of underground parking garages, protective panels are attached to the exterior walls to protect them and meet requirements for insulation and waterproofing. For example, Chinese Patent Publication No. CN218622745U describes a prefabricated parking garage with drainage-functional exterior wall protective panels and a parking garage exterior wall protection system. The protective panels consist of a protective panel, a middle panel, and an adhesive layer. In use, the protective panels are first bonded to the surface of the exterior wall using the adhesive layer. However, the protective panels are usually made of plastic. During assembly and use, plastic is prone to bending and deformation due to prolonged exposure to sunlight, resulting in bulges in the middle. Thus, in rainy conditions, rainwater is trapped by the uneven structure formed by the deformation of the protective panels, preventing rapid and effective drainage and leading to low reliability of the protective panels. Therefore, how to design a technology to improve the drainage performance of exterior wall protective panels to enhance their reliability is the technical problem this utility model aims to solve.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0042] like Figures 1-5 As shown, one embodiment of this application provides an exterior wall protection panel with drainage function, comprising:

[0043] The protective plate 1 has an inwardly flanged structure 11 on its edge, and a drainage groove 16 is provided on the outer surface of the protective plate 1. The drainage groove 16 forms a corresponding protrusion structure 17 on the inner surface of the protective plate 1.

[0044] Insulation board 2, the thickness of the insulation board 2 is not less than the thickness of the protective board 1, and the insulation board 2 is provided with a groove structure that matches the protrusion structure 17;

[0045] The insulation board 2 is attached to the inner surface of the protective board 1, the protruding structure is located in the groove structure, and the inner flange structure is arranged on the outer side of the side wall of the insulation board.

[0046] Specifically, a protective plate 1 is provided on the outer surface of the insulation board 2 in the exterior wall protective panel to shield and protect the insulation board 2. A drainage groove 16 is formed on the outer surface of the protective plate 1. During use, when two exterior wall protective panels are spliced ​​together, the drainage groove 16 will be connected accordingly, so that the water accumulated on the outer surface of the protective plate can be effectively drained smoothly through the drainage groove 16.

[0047] Meanwhile, as the drainage groove 16 is formed during the process of forming the protective plate 1, a corresponding protrusion structure 17 will be formed on the inner surface of the protective plate 1. Thus, the protrusion structure 17 formed on the inner surface of the protective plate 1 has a relatively wide width, and therefore, the protrusion structure 17 can provide better protection against bending deformation of the protective plate.

[0048] Furthermore, the drainage trough 16 includes a first water trough 161 and a second water trough 162 arranged in a cross manner, and correspondingly, the protrusion structure 17 includes a first protrusion 171 and a second protrusion 172 arranged in a cross manner.

[0049] The first protrusion 171 and the second protrusion 172 are located in the corresponding groove structure;

[0050] The first water tank is connected to the corresponding cross-arranged second water tank.

[0051] Specifically, by providing a first water trough 161 and a second water trough 162 arranged in a cross pattern on the outer surface of the protective plate, drainage can be achieved from different directions. Correspondingly, the first protrusion 171 and the second protrusion 172 arranged in a cross pattern can also more effectively strengthen the structure of the protective plate to provide better resistance to deformation.

[0052] During use, the two external wall protection panels with drainage function are spliced ​​together, and the two corresponding first water channels 161 on the two protection panels 1 are connected together, and the two corresponding second water channels 162 on the two protection panels 1 are connected together.

[0053] Based on the above technical solution, optionally, the inner surface of the protective plate 1 is also provided with a plurality of raised first reinforcing ribs 12 and a plurality of second reinforcing ribs 13, wherein the first reinforcing ribs 12 and the second reinforcing ribs 13 are arranged in a cross pattern.

[0054] The insulation board 2 is provided with a plurality of first grooves (not shown) and a plurality of second grooves (not shown), and the first grooves and the second grooves are arranged intersectingly;

[0055] The first reinforcing rib 12 is located in the corresponding first groove, and the second reinforcing rib 13 is located in the corresponding second groove.

[0056] Specifically, the first reinforcing rib 12 and the second reinforcing rib 13 of the protective plate 1 can effectively improve the structural strength of the protective plate 1. At the same time, the inner flange structure 11 of the protective plate 1 can not only improve the structural strength, but also protect the edge of the insulation plate 2.

[0057] The first reinforcing rib 12 and the second reinforcing rib 13 are distributed on the inner surface of the protective plate 1, excluding the area of ​​the protruding structure 17, so as to further strengthen the structure of the area separated from the protruding structure 17 from the inner surface of the protective plate 1 when the area of ​​the protective plate 1 is large.

[0058] Preferably, the first reinforcing rib 12 is provided with at least one first stress relief port 121; and / or, the second reinforcing rib 13 is provided with at least one second stress relief port 131; and / or, the inner flange structure 11 is provided with at least one third stress relief port 111.

[0059] Specifically, since the first reinforcing rib 12, the second reinforcing rib 13 and the inner flange structure 11 on the corresponding side of the protective plate 1 are all extended along the length or width of the protective plate 1, during the process of thermal expansion of the protective plate 1 under sunlight, one or more of the first reinforcing rib 12, the second reinforcing rib 13 and the inner flange structure 11 are provided with stress relief notches, which can effectively disperse the thermal stress generated by the plate under temperature changes.

[0060] The following explanation uses the first reinforcing rib 12 as an example. The first reinforcing rib 12 can extend along the length of the protective plate 1, and at least one first stress relief port 121 is provided on the first reinforcing rib 12. During use, the exterior wall protective plate is attached to the exterior wall of the building. After being exposed to sunlight, the protective plate 1 and the insulation plate 2 of the exterior wall protective plate absorb heat and their temperatures rise, causing the materials to thermally expand.

[0061] Because the coefficients of thermal expansion of the protective plate 1 and the insulation plate 2 may differ (the protective plate 1 is generally made of plastic, while the insulation plate 2 is generally made of polyurethane or insulation cotton), and because the first reinforcing rib 12 acts as a reinforcing structure to rigidly constrain the protective plate 1, and because the overall width of the first reinforcing rib 12 is relatively small, its resistance to deformation is lower compared to the protruding structure 17. Therefore, by providing a first stress relief port 121 on the first reinforcing rib 12, during thermal expansion, the first stress relief port 121 cuts off the continuous rigid structure of the first reinforcing rib 12, dividing it into multiple relatively independent small segments.

[0062] When the temperature rises, the stress generated by the thermal expansion of the protective plate 1 is no longer completely restrained by the first reinforcing rib 12, but can be released through local elastic deformation or small displacement near the first stress release port 121.

[0063] Similarly, the function of providing a second stress relief port 131 on the second reinforcing rib 13 and a third stress relief port 111 on the inner flange structure 11 can be referred to the description of the first reinforcing rib 12, and no limitations are made here.

[0064] Furthermore, when the first stress relief port 121 is provided on the first reinforcing rib 12; the first reinforcing rib 12 is provided with a first notch, and the first notch forms the first stress relief port 121; or, the first reinforcing rib 12 includes multiple first rib segments, and a first interval is formed between two adjacent first rib segments, and the first interval forms the first stress relief port 121.

[0065] Specifically, there are several ways to form the first stress relief outlet 121 on the first reinforcing rib 12. For example, a first notch can be formed directly on a complete first reinforcing rib 12 by cutting, and the first notch can be used as the first stress relief outlet 121. Alternatively, during the injection molding process of the insulation board 2, the mold can be designed so that the injection-molded first reinforcing rib 12 has a segmented structure, so as to form a first gap between two adjacent first rib segments, and the first gap can be used as the first stress relief outlet 121.

[0066] Furthermore, when the second reinforcing rib 13 is provided with the second stress relief port 131; the second reinforcing rib 13 is provided with a second notch, the second notch forming the second stress relief port 131; or, the second reinforcing rib 13 includes multiple second rib segments, with a second gap formed between two adjacent second rib segments, the second gap forming the second stress relief port 131.

[0067] Specifically, there are several ways to form the second stress relief outlet 131 on the second reinforcing rib 13. For example, a second notch can be formed directly on a complete second reinforcing rib 13 by cutting, and the second notch can be used as the second stress relief outlet 131. Alternatively, during the injection molding process of the insulation board 2, the mold can be designed so that the injection-molded second reinforcing rib 13 has a segmented structure, so as to form a second interval between two adjacent second rib segments, and the second interval can be used as the second stress relief outlet 131.

[0068] Furthermore, when the inner flange structure 11 is provided with the third stress relief port 111; the inner flange structure 11 is provided with a third notch, the third notch forming the third stress relief port 111; or, the inner flange structure 11 includes multiple first flange segments, and a third interval is formed between two adjacent first flange segments, the third interval forming the third stress relief port 111.

[0069] Specifically, there are several ways to form the third stress relief port 111 on the inner flange structure 11. For example, the third notch can be formed directly on the inner flange structure 11 by cutting, and the third notch can be used as the third stress relief port 111. Alternatively, during the injection molding process of the insulation board 2, the mold can be designed so that the injection-molded inner flange structure 11 is segmented, so as to form a third gap between two adjacent first flange segments, and the third gap can be used as the third stress relief port 111.

[0070] Based on the above technical solution, optionally, the protective plate 1 has a quadrilateral structure;

[0071] The inner flange structure 11 of one pair of adjacent edges of the protective plate 1 is an overlapping support flange, and the overlapping support flange forms an overlapping step surface 112.

[0072] The outer side of the inner flange structure 11 of one pair of adjacent edges of the protective plate 1 is also provided with an overlapping extension edge 14. The overlapping extension edge 14 extends outward along the plane of the protective plate 1, and an overlapping flange 141 is provided on the overlapping extension edge 14.

[0073] The height of the overlapping flange 141 is smaller than the height of the inner flange structure 11.

[0074] Specifically, in order to meet the connection requirements of two adjacent exterior wall protective panels, an overlapping step surface 112 can be formed on one pair of adjacent inner flange structures 11 of the protective panel 1, while an overlapping flange 141 can be formed on the outer side of the other pair of adjacent inner flange structures 11. During assembly, the overlapping flange 141 of one exterior wall protective panel will overlap the overlapping step surface 112 of the other exterior wall protective panel.

[0075] Furthermore, an anti-detachment space 15 is formed between the overlapping flange 141 and the relatively arranged inner flange structure 11, and a protruding limiting rib 113 is provided on the overlapping step surface 112.

[0076] For two overlapping exterior wall protective panels, the limiting rib 113 of one of the exterior wall protective panels is located in the anti-detachment space 15 of the other exterior wall protective panel.

[0077] Specifically, after the two exterior wall protective panels are joined together, the limiting baffle 113 will be inserted into the corresponding anti-detachment space 15. In this way, the limiting baffle 113 can cooperate with the overlapping flange 141 to prevent the two exterior wall protective panels from detaching.

[0078] Furthermore, at least one fourth stress relief port (not shown) is provided on the overlapping flange 141.

[0079] Furthermore, the overlapping flange 141 is provided with a fourth notch, which forms the fourth stress relief port; or, the overlapping flange 141 includes multiple second flange segments, and a fourth interval is formed between two adjacent second flange segments, which forms the fourth stress relief port.

[0080] Specifically, by additionally providing a fourth stress relief port on the overlapping flange 141, the fourth stress relief port can reduce the bulging of the protective plate 1 when it is heated and expands.

[0081] In another embodiment of this application, the protective plate 1 and the insulation plate 2 are also connected together by nails or screws.

[0082] Specifically, to more effectively prevent bulging of the protective plate 1, a mechanical connection can be used to reinforce the connection between the protective plate 1 and the insulation plate 2 at locations prone to bulging. For example, the protective plate 1 can be further connected to the insulation plate 2 in the middle area using nails or screws. That is, after the insulation plate 2 is glued to the protective plate 1, nails or screws are then tightened onto the outside of the protective plate 1 to ensure a more secure connection between the protective plate 1 and the insulation plate 2.

[0083] An embodiment of this application also provides an external wall protection system, including a plurality of the above-mentioned external wall protection panels, wherein two adjacent external wall protection panels are connected together.

[0084] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions claimed in this application.

[0085] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
