Description

Technical Field

[0001] This utility model relates to the field of wall technology with moisture-proof function, and in particular to a wall with moisture-proof function. Background Technology

[0002] The existing patent publication number (CN222206848U) discloses a moisture-proof wall, including a wall assembly, a water-absorbing layer, a heat transfer assembly, and an evaporator. The wall assembly includes a first wall and a second wall, with a cavity formed between them. The water-absorbing layer is disposed within the cavity. One end of the heat transfer assembly is located on the outer surface of the wall assembly, and the other end extends into the cavity. The evaporator is disposed on the wall assembly. The heat transfer assembly conducts external heat to the water-absorbing layer, causing the moisture on the water-absorbing layer to evaporate and be discharged through the evaporator. The moisture-proof wall provided above absorbs heat from sunlight through the heat transfer assembly and conducts it to the water-absorbing layer, raising the temperature in the water-absorbing layer and accelerating the vaporization of water. The gaseous water enters the evaporator and then condenses back into water, which is discharged to the outside. This method solves the problem of water easily remaining inside the wall.

[0003] However, we know that the existing wall structure is a reinforced concrete frame with latex paint and mortar coating applied to the outside of the concrete. The patented structure mentioned above is completely detached from the existing technology, has very low practicality, and is very expensive.

[0004] This proposal is put forward in order to improve and optimize the above-mentioned problems or shortcomings. Utility Model Content

[0005] A moisture-proof wall, comprising a cement wall layer made of reinforced concrete;

[0006] A latex paint layer is provided on the surface of the cement wall layer, and a moisture-proof composite wallpaper is attached and fixed to the outside of the latex paint layer by adhesive.

[0007] The moisture-proof composite wallpaper is composed of a multi-layer structure, including at least one moisture-absorbing layer, whose moisture absorption performance is higher than that of the latex paint layer.

[0008] Preferably, the moisture-proof composite wallpaper includes non-elasticized chemical fiber fabric, breathable membrane, and polyethylene composite wallpaper, wherein the polyethylene composite wallpaper is located on the outermost side, and the non-elasticized chemical fiber fabric is bonded to the moisture-absorbing foam layer.

[0009] Preferably, the breathable membrane is provided with vent holes at intervals. When the humidity outside the wall is greater than the humidity inside the wall, the breathable membrane will partially isolate it and allow some moisture to be absorbed inward through the vent holes. This is to facilitate the breathing and ventilation of the cement wall layer, because cement still needs to maintain a reasonable humidity after it has been poured and formed.

[0010] Preferably, the non-elasticized synthetic fiber fabric and the breathable membrane are bonded together with waterproof adhesive, and the breathable membrane and the polyethylene composite wallpaper are bonded together with waterproof adhesive.

[0011] Preferably, the back of the non-elasticized synthetic fiber fabric is provided with water-absorbing flocked fibers, which are embedded in the moisture-absorbing foam layer. Specifically, the moisture-proof composite wallpaper is attached to the moisture-absorbing foam layer before it is fully formed, so that the water-absorbing flocked fibers are partially embedded in the moisture-absorbing foam layer. The moisture-absorbing foam layer is then formed and fixed.

[0012] Preferably, the fibers on the absorbent flocked fibers are located between the breathable membrane and the adhesive surface of the polyethylene composite wallpaper through the air pores.

[0013] The advantages and positive effects of this utility model are:

[0014] This application is a reasonable and scientific innovative improvement based on the existing wall structure. By attaching moisture-absorbing and water-repellent composite wallpaper to the surface of the wall, most of the moisture is excluded, while ensuring that the concrete wall has a certain degree of breathability. Compared with the existing technology, it effectively improves the moisture-proof performance of the cavity during the plum rain season and reduces the occurrence of mold, blistering and peeling on the cavity surface.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0020] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movement of the components in a specific posture (as shown in the accompanying drawings); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance. The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings:

[0021] like Figure 1-2 As shown, the wall with moisture-proof function described in this utility model includes a cement wall layer 10 made of reinforced concrete.

[0022] A latex paint layer 11 is provided on the wall surface of the cement wall layer 10, and a moisture-proof composite wallpaper 13 is attached and fixed to the outside of the latex paint layer 11 by adhesive.

[0023] The moisture-proof composite wallpaper 13 is composed of a multi-layer structure, including at least one moisture-absorbing layer, whose moisture absorption performance is higher than that of the latex paint layer 11.

[0024] Preferably, the moisture-proof composite wallpaper 13 includes a non-elasticized chemical fiber fabric 16, a breathable membrane 15, and a polyethylene composite wallpaper 14, wherein the polyethylene composite wallpaper 14 is located on the outermost side, and the non-elasticized chemical fiber fabric 16 is bonded to the moisture-absorbing foam layer 12.

[0025] Preferably, the breathable membrane 15 is provided with breathable holes 17 at intervals. When the humidity outside the wall is greater than the humidity inside the wall, the breathable membrane 15 will partially isolate it and allow some moisture to be absorbed inward through the breathable holes 17. This is to facilitate the breathing and ventilation of the cement wall layer 10, because the cement still needs to maintain a reasonable humidity after it is poured and formed.

[0026] Preferably, the non-elasticized synthetic fiber fabric 16 and the breathable membrane 15 are bonded together with waterproof adhesive, and the breathable membrane 15 and the polyethylene composite wallpaper 14 are bonded together with waterproof adhesive.

[0027] Preferably, the back of the non-elastic synthetic fiber fabric 16 is provided with water-absorbing flocked fibers 18, which are embedded in the moisture-absorbing foam layer 12. Specifically, the moisture-proof composite wallpaper 13 is attached to the moisture-absorbing composite covering wallpaper 13 during the stage when the moisture-absorbing foam layer 12 is not fully formed, so that the water-absorbing flocked fibers 18 are partially embedded in the moisture-absorbing foam layer 12. The moisture-absorbing foam layer 12 is then formed and fixed.

[0028] Preferably, the fibers on the absorbent flocked fibers 18 are partially located between the breathable membrane 15 and the adhesive surface of the polyethylene composite wallpaper 14 through the air vents 17.

[0029] It should be emphasized that the embodiments described in this utility model are illustrative rather than limiting. Therefore, this utility model is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this utility model are also within the scope of protection of this utility model.
