Embodiment 1

[0030] To deal with mildew at the corner of the inner wall 900x800mm, the maintenance steps are as follows:

[0031] 1) Within the area of ​​1000x1000mm on the exterior wall corresponding to mildew and its surroundings, hit the wall with a hand hammer to hear the echo of "Weng Weng" in many places. It is preliminarily judged that there may be internal voids or pine looseness. Use a hand hammer to pierce a steel needle into the wall to investigate the depth of the cavity or crack at the deepest point of 200mm, and determine the defect range to be 1000x1000mm around the mildew.

[0032] 2) see figure 2 , on the outer wall, use an electric drill to drill 20 injection molding holes from the periphery of the determined defect range of 1000x1000mm, the hole distance is 200mm, the hole diameter is 30mm, and the maximum depth is 210mm, which is less than 1 / 2 of the wall thickness (the measured wall thickness is 450mm). Effectively frame the defect within the processing range; punch ...

Embodiment 2

[0037] The range of mildew at the treatment window is 800x100mm, and the maintenance steps are as follows:

[0038] 1) In the 900x120mm range of the outer wall corresponding to mildew and its surroundings, no obvious "Weng Weng" echo can be heard when hitting the wall with a hand hammer using the percussion method. It is preliminarily judged that there may be internal looseness or cracks. Use the hand hammer to pierce the steel needle into the deepest hole or crack of the wall to check the depth of 180mm, and determine the defect range to be 900x120mm around the mildew.

[0039] 2) see image 3 , on the outer wall, use an electric drill to drill 8 injection molding holes from the periphery of the determined defect range of 900x120mm, the hole distance in the length direction is 300mm, the hole distance in the width direction is 120mm, the hole diameter is 30mm, and the maximum depth is 200mm, which is less than 1 / 2 of the thickness of the wall (measured The thickness of the w...

Abstract

The invention relates to a maintenance method for building interior wall surface mildewing and belongs to the technical field of buildings. Polyvinyl chloride (PVC) filler or a water-soluble polyurethane grouting material is sprayed into a wall through an injection molding machine or a grouting machine, and hidden danger, namely, holes or looseness or cracks inside the wall, causing interior wall mildewing is eliminated. Compared with the prior art, the maintenance method has the beneficial effects that the interior wall surface mildewing problem caused by water leakage or cold penetration generated due to the interior defects such as the holes, looseness and cracks of the building wall can be effectively solved through the method.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a maintenance method for mildew on the inner wall surface of a building. Background technique [0002] Due to the influence of factors such as material selection, improper construction, or long-term rain in the rainy season or long-term wind, rain, and sun, the building walls are likely to have cavities, pine cracks, water leakage, and through-cold, which will cause internal wall surfaces. Mildew not only pollutes the environment, endangers personal health, reduces the strength of the wall, but also affects the appearance of the interior. At present, for internal defects in the wall, such as hollows, looseness or cracks in the corners, doorways, and window sills, it is difficult to find them due to technical or other reasons. Even if they are found, the traditional maintenance method is to fill them up with mortar, and some say more. Apply a layer of waterproof paint, and rede...
