Description

External wall waterproofing method

The invention relates to a method for treating a waterproof leaking project; in particular, a method for treating a waterproof leaking method for a wall of a building.

Most of the conventional buildings are made of bricks or cement coated with steel bars, and then the outer wall surface is covered with tiles according to the needs of use. Although the reinforced concrete itself has a waterproof effect, it must be used when the knot is complete. When a building is damaged due to an earthquake or is in disrepair, it will cause cracks in the building. When it is raining or humid, water or moisture will seep from the cracks in the building, causing the building to leak water. Buildings have more or less problems with water leakage. Most people think that as long as the tile is attached, it can have the effect of waterproofing. However, even if the tile is attached, the water will still enter the outer wall through the gap of the tile, causing water leakage or wall cancer, and the tile The crack on the outer wall is covered, but the crack cannot be easily observed.

In addition, after the external wall waterproofing repair, the problem often arises: because the wall surface of the outer wall is easily covered with moss, dirt and powder layer and difficult to remove, resulting in poor construction of the waterproof operation. Even if the waterproofing operation is completed, there is still the possibility of peeling off; in addition, because the external wall is affected by the sun, rain, and day and night temperature difference, new cracks are likely to occur even after the waterproofing operation is completed. The leaking situation reappeared.

In view of this, the inventors have conceived and further studied, and finally invented a method for external wall waterproofing.

The invention provides a method for waterproofing external wall, the main purpose of which is to enable the outer wall to have a good application surface during waterproof construction, to avoid spalling due to poor application surface after the completion of construction; The surface of the wall is easily cracked again due to the effects of sun, rain and temperature difference between day and night.

To achieve the foregoing objective, the present invention provides an external wall waterproofing method comprising the steps of: high pressure cleaning; cleaning the impurities on the application surface of the outer wall with a high pressure water column; and then applying a substrate to the substrate. The surface of the outer wall is used to level the unevenness on the outer wall; the fiberglass mesh is laid outside the substrate with a fiberglass mesh to increase the crack resistance; the high tension composite glue is applied to the composite rubber a fiberglass mesh, the glass fiber mesh is bonded to the substrate, and the gap of the glass fiber mesh is flattened; the middle layer is cured, and the fixing material is uniformly coated on the composite rubber, and the fixing material is applied The thickness is between 0.5mm and 1.5mm to fix the composite glue and the glass fiber mesh; and the top coat is coated on the fixing material with a heat-insulating frost, the heat-insulating frost has high heat-proof effect and high Force, hydrophobic, water resistant and good ductility.

The invention utilizes the provided external wall waterproofing method to obtain the effect that the powder layer and the dust on the application surface are sprayed off by cleaning the application surface of the outer wall with a high-pressure water column, and the invention has good Applied surface; and on the substrate A fiberglass mesh is laid outside to reinforce the structure of the outer wall by the high tensile strength of the fiberglass mesh to avoid cracks.

A preferred embodiment of the external wall waterproofing method of the present invention is as shown in Figs. 1 to 4, and is applied as a waterproof layer 50 outside the outer wall 30. The application method comprises the following steps: high pressure cleaning 201, followed by bottom Material 202, crack treatment 203, elastic waterproof material 204, glass fiber mesh 205, high tension composite adhesive 206, intermediate curing 207, and topcoat 208, wherein: The high pressure cleaning 201 cleans the impurities 32 on the application surface 31 of the outer wall 30 by the high pressure water column 41, and the impurities 32 include moss, dirt, powder layer or other impurities or contaminants, etc.; There should be no existence of any impurities 32 between the faces 31. Otherwise, the adhesion of the application surface 31 may be affected by the contamination of the materials in the subsequent construction, thereby causing poor waterproofing effect, resulting in a decrease in the waterproof life of the outer wall 30; The adhesion between the waterproof layer 50 and the outer wall 30 is implemented. Therefore, the inventor of the present invention thoroughly cleans the impurities 32 on the outer wall 30 with the high-pressure water column 41, and reduces the powder layer and dust of the original outer wall by high-pressure washing. Therefore, the application surface 31 can have a better adhesion surface; then the substrate 202 is coated with a substrate 52 on the application surface 31 of the outer wall 30 to level the unevenness on the outer wall 30. In order to provide a better adhesive surface, in this embodiment, the inventor of the present invention uses cement as the substrate 52; the crack treatment 203 checks whether there is a crack 33 on the application surface of the outer wall 30, and each of the cracks 33 Filling the process to reinforce the structural weakness of the outer wall 30 And according to the material at the corner of each weak point to determine the waterproof construction method to increase the strength of waterproofing, this case is to fill the crack 33 on the application surface 31 with the Silicone 51 to ensure that there is no crack 33 on the external wall 30 after construction; If there is a crack 33 on the outer wall 30 after the construction, when the outer wall 30 is affected by the sun, the rain, and the temperature difference between day and night, the stress is easily concentrated at the crack 33, so that the crack 33 is enlarged, resulting in water leakage, and therefore, the crack 33 The filling is one of the steps necessary for waterproof construction; the elastic waterproof material 204 is coated on the substrate with a waterproof material 53 52; a fiberglass mesh 205 is laid on the substrate 52 and the waterproof material 53 by a fiberglass mesh 54. The outer wall 30, the substrate 52 and the waterproof material 53 are supported by the strength of the fiberglass mesh 54 to provide tensile stress. In order to increase the crack resistance, the outer wall 30 is again cracked due to external force after the construction; the high tension composite glue 206 is applied to the glass fiber mesh 54 by the composite glue 55, so that the glass fiber mesh 54 is tightly bonded to the bottom. The material 52 and the waterproof material 53 and flatten the gap of the glass fiber mesh 54; the middle layer is cured 207, which is uniformly coated on the composite glue 55 by a fixing material 56, and the thickness of the fixing material 56 is introduced. Between 0.5 mm and 1.5 mm, and preferably 1 mm, to fix the composite glue 55 and the glass fiber mesh 54; and a top coat 208, which is coated with a heat-insulating cream 57 on the fixing material 56, the partition Hot Cream 57 has high heat resistance, high adhesion, hydrophobicity, water resistance and good ductility.

In addition, a protective layer may be further coated on the waterproof layer 50 to increase the service life of the waterproof layer 50, and the service life of the waterproof layer 50 may be extended after the construction; The series of materials must be constructed under the condition that the concrete is wet. Other waterproof materials must be placed under the strong surface of the joint surface to continue the construction to maintain the waterproof effect of the waterproof material. In addition, in order to complete the integrity of the waterproof material, in addition to the cement series The waterproof material of cement mortar can be used for waterproofing under the condition that the concrete surface is slightly rough. The sheet material or the coating material must be completely waterproof before the surface can be applied to achieve waterproofing. The effect.

It is worth noting that since the case supports the outer wall 30, the substrate 52 and the waterproof material 53 by the strength of the fiberglass mesh 54, providing tensile stress to increase the crack resistance, therefore, the crack treatment 202 step is unnecessary. The step can be replaced by the glass fiber mesh 205, so that the construction time can be saved, and at the same time, the quality of the construction can be ensured.

From the above, it is known that the present invention truly conforms to "industrial availability," "novelty," and "progressiveness", and submits an invention patent application in accordance with the law, praying for review and early granting of a patent, and it is truly sensible.
