Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to an external protective insulation layer installation structure. Background Art

[0002] Insulation board is a kind of building material. During construction, the insulation board needs to be installed on the outer surface of the exterior wall. When installing the insulation board on the exterior wall, glue is used to bond the wall and the insulation board, and then holes are drilled in the wall and the insulation board. The insulation board is fixed to the wall with expansion bolts, and then the exposed anchors are sealed and covered with sealant. This method of installing the insulation board will still cause water seepage after the sealant ages.

[0003] Chinese patent publication number CN102505766B discloses a device for installing and fixing exterior wall insulation panels, comprising a pressing piece, a wall fixing piece, and a connecting piece. The pressing piece has a pressing piece perpendicular to the main body at its tail end, and a fixing hole at its head end. One end of the connecting piece has an external thread, and the other end has an axial groove that divides the end into at least two elastic pieces. Each elastic piece has a barbed protrusion axially disposed on its outer surface that mates with the fixing hole. The wall fixing piece has an expansion joint at its head end, an internal thread at its tail end face, and a fixing hole that penetrates the expansion joint at its bottom wall. The fixing piece also includes an expansion nail that can be inserted into the fixing hole. This installation and fixing device significantly enhances the strength of the insulation board because the pressing piece is pre-buried in the insulation board. It also ensures that the insulation board is on the same horizontal plane during installation. It eliminates the need to damage the outer surface of the insulation board, making the wall more aesthetically pleasing after installation.

[0004] The above-mentioned external wall insulation board installation and fixing device is connected to the insulation board by the pressing piece that passes through the insulation board and the connecting piece and the wall fixing piece to achieve the installation of the insulation board, and waterproof sealing is achieved by applying insulation board mortar material on the outside of the insulation board. This installation method still requires drilling holes in the insulation board. If the insulation board mortar material is damaged or cracked in the later stage, water seepage will still occur. There are still certain deficiencies in the waterproof installation of the insulation board. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0020] Unless otherwise specifically stated, the relative arrangement of the parts and steps, the numerical expressions and the numerical values ​​set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The techniques, methods and equipment known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and equipment should be considered as part of the authorization specification. In all examples shown and discussed here, any specific values ​​should be interpreted as being merely exemplary and not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0021] In the description of the present invention, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.
