[Prior art]

 For buildings, for example, high-rise buildings, it is necessary to waterproof the roof and veranda after building the building. In the case of concrete buildings, the underlay to be waterproofed is made of concrete, so waterproofing is performed using asphalt.However, in the case of wooden houses, plywood panels etc. are often placed on the base of the veranda. It is not recommended to use asphalt for waterproofing because it is used.

[0005] Recently, an FRP waterproofing method for waterproofing using fiber reinforced plastic has been put to practical use, and has been tending to be used for waterproofing works such as verandas of wooden houses.

Conventionally, in this type of FRP waterproofing method, cleaning of a base, application of a primer resin and curing for 0.5 to 1 hour, application of an undercoat resin, application of glass cloth, application of an undercoat resin, and 1 to 2 hours Waterproofing work was carried out through the steps of curing, defoaming, applying an intermediate coating resin, curing for 1 to 2 hours, surface polishing (sanding treatment), and applying a top coat resin.

[0005]

[Problems to be solved by the invention]

 However, in the conventional FRP waterproofing method, a synthetic resin is directly applied to the underlying plywood panel or concrete to form a waterproof layer. When transmitted to the waterproof layer, cracks and the like enter the waterproof layer, and if the crack is large, water leakage may occur.

[0006] Further, in the conventional FRP waterproofing method, most of the work is performed on the construction site, so the work efficiency is poor, the construction time is long, and if the waterproof part is wet with rainwater or the like, it will be dried. There was also a problem that construction could not be started.

Further, in the conventional FRP waterproofing method, it is necessary to polish the surface of the intermediate coating resin layer before applying the top coat resin. However, when the intermediate coating resin layer is polished, a large amount of dust is generated. However, there was a problem that it was difficult to perform waterproofing work in dense residential areas.

The inventors of the present invention have developed a waterproofing method capable of efficiently performing an operation in a short time, generating almost no dust and odor, and guaranteeing excellent waterproofing performance.

The present invention provides a soft resin used in a waterproofing method capable of efficiently performing an operation in a short time in such a situation, hardly generating dust and odor, and guaranteeing excellent waterproof performance. The task is to provide a panel.

[0010]

[Means for Solving the Problems]

 Therefore, the soft resin panel for waterproofing work according to the present invention is a soft resin panel used for waterproofing work, a plurality of which are arranged side by side and integrated with each other. It is manufactured in a substantially rectangular shape with a thickness of a predetermined size and a reinforcing fiber is interposed in the middle in the thickness direction, and a part of the reinforcing fiber protrudes from one side or two orthogonal sides of the rectangular shape. The protruding reinforcing fibers are overlapped on the adjacent soft resin panel or on the reinforcing fibers protruding from the adjacent soft resin panel, and a waterproof resin material is applied to a portion where the reinforcing fibers are overlapped. Thus, adjacent soft resin panels can be integrated with each other.

One of the features of the present invention is that the undercoat and the undercoat resin material are not applied to the waterproof portion, but have the undercoat resin layer, the reinforcing fiber and the layer corresponding to the intermediate coating resin layer and the reinforcing fiber in the conventional method. A flexible resin panel is manufactured in advance at a factory or the like, and it is lined up in a waterproof area, and the reinforcing fiber of the soft resin panel is overlapped with the adjacent soft resin panel or its reinforcing fiber, and a resin material is applied. The soft resin panels of the present invention can be integrated with each other to a size that covers the waterproof part.

As a result, the application of the primer resin and the curing for 0.5 to 1 hour, the curing of the undercoat and the intermediate coating resin in the conventional method are not required, and the work process is simplified and the construction time is greatly reduced. Can be. According to the experiments conducted by the present inventors, it was confirmed that the conventional method could take about 7 hours to waterproof 10 m ² , whereas the present invention could complete the work in about 3 hours. Was.

The integrated soft resin panel is preferably elastically bonded with an elastic adhesive of a predetermined size scattered on the base. The elastic adhesive absorbs the sway even if a large sway due to an earthquake or the like acts, making it difficult for the integrated resin panel itself to exert a large sway, and the integrated resin panel itself has a certain degree of softness. Therefore, cracks and the like hardly occur in the resin panel, and excellent waterproof performance can be guaranteed. Here, the elastic adhesive refers to an adhesive that maintains the required elasticity even after the bonding is completed.

The same resin material is preferably applied to integrate the softened resin panel at the work site. It is only necessary to polish the surface of the resin material applied to the overlapping portion of the reinforcing fiber and the soft resin panel, which can prevent dust and odor, and can easily perform waterproofing work even in dense residential areas. is there.

The soft resin panel according to the present invention has a great effect when applied to waterproofing work on a veranda of a new wooden house or a rooftop of a building, but can be similarly applied to repair work of a waterproof part.

A veranda or a roof generally comprises a flat part and a rising part. When waterproofing work is performed on a veranda or a roof, a reinforcing fiber is formed in a substantially rectangular plane and in the middle in the thickness direction. Fixing the waterproof waterproof soft resin panel to the rising portion, and causing the reinforcing fibers protruding from the soft resin panel on the base to overlap the soft resin panel at the rising portion; and A step of applying a waterproof resin material to a portion where the reinforcing fibers are stacked to integrate adjacent soft resin panels with each other.

Usually, in a wooden house, a drainage is often provided between a veranda and an entrance or between a veranda and an outer wall. Therefore, it is preferable to arrange the upper edge of the soft resin panel at the rising portion inside the drainage hardware to prevent moisture such as rainwater from entering the room. When there is no drainage between the veranda and the outer wall, the upper edge of the soft heavy panel at the rising portion is preferably arranged in the outer wall.

Further, a waterproof structure obtained by the soft resin panel according to the present invention is also novel. That is, according to the present invention, of the portion including the base and the rising portion, at least a waterproof structure provided on the base, and a waterproof layer of a predetermined size in which a waterproof layer is disposed in a dotted shape on the base. The waterproof layer is elastically bonded by an elastic adhesive, and the waterproof layer is composed of at least two layers, a lower layer and a top coat layer. The lower layer has a substantially rectangular shape in a plane and a reinforcing fiber is interposed in the middle in the thickness direction. A plurality of waterproof soft resin panels in which a part of the reinforcing fibers protrude from one side or two sides orthogonal to the rectangular shape are arranged, and the protruding reinforcing fibers of the soft resin panel overlap the adjacent soft resin panels. In addition, it is possible to provide a waterproof structure for a building characterized by being formed by applying a resin material exhibiting waterproofness to a portion where the reinforced fibers are overlapped and integrally formed with each other.

This waterproof structure further includes a rising waterproof layer covering the rising portion. The rising waterproof layer has a substantially rectangular shape in a plane at the rising portion and a reinforcing fiber is interposed in the middle in the thickness direction. A plurality of waterproof soft resin panels in which a part of the reinforcing fibers protrude from one side or two sides orthogonal to each other are arranged, and the reinforcing fibers protruding from the soft resin panel are superposed on the lower soft resin panel. Preferably, a resin material exhibiting waterproofness is applied to a portion where the reinforcing fibers are overlapped, integrated with each other, and a top coat layer is formed thereon.

In addition, in the waterproofing method and structure using the soft resin panel according to the present invention, since the resin material is not applied to the waterproof portion, the waterproofing work can be performed even when the waterproofing portion is wet with rainwater or the like. It can be started, but in this case, it is better to have a structure that releases rainwater etc. to the atmosphere. Therefore, it is preferable that a part of the rising waterproof layer be provided with a ventilation part which constitutes a ventilation space between the rising part of the building and the place where water protection is required.

The material of the soft resin panel may be a resin material used for waterproofing work, and a high water-resistant vinyl ester resin for intermediate coating used for waterproofing a roof, a roof or a veranda, and methyl ethyl ketone peroxide. It is preferable to use a kneaded product with a curing agent.
