Description

The waterproofing method of buildings}

The present invention relates to a waterproof construction method of a building for preventing leakage caused by cracks (cracks) generated on the bottom or corners of a building, and more specifically, the projections and latents of a base surface. A pretreatment step of removing a factor that inhibits adhesion, such as dirt; Filling silica between cracks or cracks generated; Applying and curing a low viscosity permeable primer on the base surface; Attaching a reinforcing tape to a site where cracks or cracks have occurred or a site where a further crack has occurred; Mixing and applying a urethane resin and a silica-based inorganic filler; And a step of applying a urethane resin, and further comprising a step of installing a glass fiber mesh having a honeycomb structure after the reinforcing tape attaching step, if necessary, to perform waterproofing, thereby forming a base surface and a resin coating layer. It is to be separated, and the waterproof construction method of the building to obtain the effect of preventing the leakage phenomenon occurs even if cracks or cracks due to the elasticity of the reinforcing tape and the glass fiber mesh of the honeycomb structure.

In general, the roof of a building has a waterproof function to prevent precipitation, reduces the heat load of solar radiation caused by sunlight, and insulates to keep the heat inside or block the outside heat, and the roof by snow load and weather load. Considering the ability to handle the loading load acting on the surface, a waterproof construction using a suitable waterproof method and waterproofing material is being performed.

Conventional roof waterproofing includes rubber asphalt waterproofing, urethane coating waterproofing, asphalt waterproofing (heating method) construction methods. Deterioration such as swelling, cracking, peeling, and fracture occurs due to chemical and physical deterioration factors and external force (eye, rain), which causes dissimilar materials such as parapat and drain, and stress concentrations. There are many leaks.

On the other hand, the sheet waterproofing method is also used a lot, as the waterproof sheet used for the waterproof sheet is generally used a lot of improved asphalt sheet excellent in waterproof performance, but poor in construction.

There are two types of improved asphalt sheet methods that can be applied only by peeling the release paper from a sheet having a self-adhesive property or a method using a hot melt asphalt or an adhesive. Currently, the most commonly used waterproof sheet construction method is a method of spreading and attaching the sheet to the concrete slab in a molten state by heating the asphalt attached to the back of the waterproof sheet with a propane gas burner (torch burner).

Such improved asphalt has a problem of poor installation efficiency and difficulty in securing watertightness of the joint part because the asphalt must be subjected to reinforcement work after the front attachment to the concrete slab of each asphalt sheet and the joint part treatment between the asphalt sheets.

On the other hand, when the waterproof construction is performed by the conventional general waterproof construction method, because the base surface and the coating layer or the base surface and the sheet layer is closely coupled, if the crack or crack occurs on the base surface or the crack or crack already generated If it proceeds, the coating layer or the sheet layer ruptures or is damaged, causing leakage, which has a disadvantage in that the waterproof effect is not continuous.

Therefore, an object of the present invention is that the leakage does not occur even if cracks or cracks are generated, and if the cracks or cracks that have already occurred further progress, there is no rupture or breakage of the coating layer or the sheet layer, so that the waterproofing effect can be obtained. To provide a waterproof construction method.

In order to easily achieve the above object as well as other objects that can be easily expressed, the present invention includes a pre-treatment step of removing factors such as adhesion on the base surface, latent (latent), dirt, etc. inhibiting adhesion; Filling silica between cracks or cracks generated; Applying and curing a low viscosity permeable primer on the base surface; Attaching a reinforcing tape to a site where cracks or cracks have occurred or a site where a further crack has occurred; Mixing and applying a urethane resin and a silica-based inorganic filler; And a step of applying a urethane resin, and further comprising a step of installing a glass fiber mesh having a honeycomb structure after the reinforcing tape attaching step, if necessary, to perform waterproofing, thereby forming a base surface and a resin coating layer. The separation and the elasticity of the fiberglass mesh of the reinforcing tape and the honeycomb structure to obtain the effect of preventing the leakage phenomenon occurs even if cracks or cracks.

The waterproof construction method of the building according to the present invention allows the base surface and the resin coating layer to be separated, and the leakage phenomenon does not occur even if cracks or cracks occur due to the elasticity of the reinforcing tape and the glass fiber mesh of the honeycomb structure. You can get it.

The waterproof construction method of the building according to the present invention includes a pretreatment step of removing factors such as protrusions, latents, dirt, etc., which hinder adhesion to the base surface 1; Filling silica 4 between cracks or cracks 3 generated; Applying a low viscosity permeable primer to the base surface 1 and curing to form a low viscosity permeable primer layer 5; Attaching the reinforcing tape 6 to the site where the crack or crack 3 has occurred or the site where the additional crack has occurred; Mixing and applying a urethane resin and a silica-based inorganic filler to form a waterproof layer 7; And it is characterized by consisting of the step of applying a urethane resin.

In addition, the waterproof construction method according to the present invention may add a step of installing a glass fiber mesh (mesh: 8) of the honeycomb structure after the step of attaching the reinforcing tape.

First, a pretreatment step is performed to remove factors that hinder adhesion such as protrusions, latents, and dirt on the base surface 1 to be waterproofed.

That is, the waterproof construction method of the present invention, which is a kind of waterproof coating method, inhibits adhesion of the reinforcement tape 6 or the urethane resin because the reinforcement tape 6 should be attached to the base surface 1 or urethane resin should be applied. The foreign substance to be removed should be removed in advance.

In addition, it is preferable to remove all the waterproof construction materials when re-installing the base surface where the waterproof construction has already been carried out, and even in the case of new buildings, it is preferable to perform pretreatment because there are many foreign substances in the base surface during construction.

As a pretreatment step for removing a factor that hinders adhesion of the base surface 1, any method commonly used in the art to which the present invention pertains may be used.

After the above pretreatment step, silica 4 is filled between cracks or cracks 3 generated. Silica-based fillers, cement mortar, etc. may be used instead of the silica (4), and if not filled between the cracks or cracks (3) generated, not only problems such as sound insulation and heat insulation, but also become difficult to uniform waterproof construction Disadvantages arise.

Other additives such as thickeners, waterproofing agents, rust inhibitors, and the like commonly used in the art to which the present invention pertains may be added to the silica (4), silica fillers, cement mortars, and the like.

However, in the case of new buildings without cracks or cracks 3, the step of filling silica (4), silica-based filler or cement mortar is omitted, and the low-viscosity permeability to the base surface (1) immediately after the pretreatment step The primer is applied and cured to grow.

After filling the silica (4), silica filler or cement mortar between the cracks or cracks (3) as described above, by applying a low-viscosity permeable primer to the entire base (1) and curing the low-viscosity permeable primer (5) Form a layer.

The steps of filling the silica 4 between the cracks or cracks 3 generated and applying and curing the low viscosity permeable primer on the base surface 1 may be reversed.

The reason for applying the low viscosity permeable primer is to easily apply the resin to be applied later on the base surface 1, and to improve the adhesive force. Low viscosity permeable primer (5) can be used all of those commonly used in the art to which the present invention belongs, and are not particularly limited.

The method of applying the low viscosity permeable primer is not particularly limited, and all of the methods commonly used in the art to which the present invention pertains may be used, and in the present invention, a coating roller is used.

After applying the low-viscosity permeable primer, the reinforcing tape 6 is attached to the site where the crack or crack 3 has occurred or the site where the additional crack has occurred.

The reinforcing tape 6 has an adhesive property on one surface (the surface adhered to the base surface), and the other surface (the upper surface) is coated so that any resin can be used in the future. Although it is not specifically limited, Width 10? 50 mm, thickness 0.5? It is effective that it is about 3.0 mm.

In addition, the reinforcing tape 6 is preferably made of a flexible material in the width direction in order to maintain the bonded state with the base surface even if cracks or cracks 3 occur or further progress.

In addition, the reinforcing tape 6 has no adhesive ability at the center portion in the width direction, and only cracks or cracks 3 and the reinforcing tape 6 are configured to have no adhesive ability at both end portions thereof. effective.

In particular, when the wall 2 is connected to the base surface 1 in the vertical direction, and the crack occurs in the corner portion between the base surface 1 and the wall 2 is shown in Fig. 6 or 7 As described above, it is preferable that both sides of the reinforcing tape 6 are bonded to the base surface 1 and the wall 2 while being separated without being bonded to the edge portion.

After adhering the reinforcing tape 6 as described above, the urethane resin and the silica-based inorganic filler are mixed and applied to form the waterproof layer 7. In this case, the urethane resin and the silica-based inorganic filler can be used both the urethane resin and the silica-based inorganic filler for waterproof construction commonly used in the technical field to which the present invention belongs, and select and apply an excellent waterproof effect, and apply The thickness is not particularly limited, but 1.5? 2.0 mm is preferable and 2? It may apply | coat repeatedly three times.

The method of forming the waterproof layer 7 may also use all methods commonly used in the art to which the present invention pertains, such as spray coating and roller coating.

After forming the waterproof layer 7 as mentioned above, the urethane resin used at the time of forming the waterproof layer 7 is made into 2? Repeated coating and curing three times to form a protective layer (not shown) to complete the waterproof construction.

Meanwhile, as another embodiment of the present invention, as shown in FIG. 5, the glass fiber mesh having a honeycomb structure after attaching the reinforcing tape 6 to the site where the crack or the crack 3 is generated or the site where the additional crack is expected to occur. You can also add steps to install (mesh: 8).

That is, the honeycomb structured glass fiber mesh (mesh 8) is installed on the reinforcing tape 6, and cured while impregnating a mixture of a urethane resin and a silica-based inorganic filler, and a fiberglass mesh having a honeycomb structure. 8) Because it has excellent elasticity in all directions, even if cracks or cracks (3) are severely generated, the waterproof layer (7) is protected as it increases, and the waterproofing effect is continuously displayed.
