Description

[Detailed description of the invention] Industrial applications The present invention relates to a filling material for gaps between tiles on the roof of a house.

Conventional technology The gaps between tiles on the roof of a house have traditionally been filled with "plaster".This method involves adding water to the "plaster" and applying it with a trowel, which is complicated and time consuming. It takes,
In addition to getting your hands dirty, there were other drawbacks such as the "plaster" freezing in winter or in cold regions, making it impossible to work.

Purpose of the Invention The present invention aims to solve the drawbacks of conventional "plaster" use, and provides a filling material for gaps between roof tiles that is easy to handle and can be easily installed even in winter or in cold regions. It is in.

Structure of the Invention As a result of intensive research to achieve the above object, the present inventor used a flexible member in which one or more surfaces of the flexible member were formed into an uneven shape and covered with a coating layer made of rubber or the like, When this is used to fill the gaps between tiles, it can be easily installed by simply compressing and inserting the tiles, and since the surface is coated with water-resistant synthetic resin, metal or rubber, it is waterproof and the top It is compressed uniformly and can seal gaps without being irregularly compressed due to surface irregularities and causing large wrinkles locally. It was also found that installation is easy even in winter or in cold regions. The present invention was completed based on this knowledge.

The filling material for gaps between roof tiles of the present invention will be explained based on the drawings. Figure 1 shows an embodiment in which the unevenness is mountain-shaped, and Figure 2 shows an embodiment in which the unevenness is table-shaped. It is used. The uneven shape is not limited to this, and any shape may be used as long as it achieves the object of the present invention.

In the figure, 2 indicates a flexible member. This flexible member is
f 1/7 + Polyolefin polymers such as polypropylene and polyvinyl chloride, plastic foams such as polyurethane resins, synthetic rubbers such as chloroprene rubber and ethylene propylene rubber, and foams such as natural rubber. . Open cell foam that can be compressed more freely than closed cell foam (closed cell ratio 50% or less, preferably 3
0% or less). Also, the density of the foam is 0. The hardness at 50% compression is preferably 2009/am2 or less. If the density is less than 0.01, when compressed with tiles or the like, the stress resulting from the density is small, and the hardness decreases significantly over a long period of time, causing the material to fall off. Moreover, if the density is 0.2 or more, the hardness resulting from the density will be large and the tiles on the top surface will not be stably installed.

Furthermore, if the compression ratio becomes 5 times, compression becomes impossible.

If the hardness at 50% compression exceeds 200 f/cm2, the hardness will be too great when placing tiles on the top surface, and compression will not be sufficient. Moreover, workability becomes worse.

In addition, the material is not limited to foam, and may be a woven structure made of paper or resin, or a rutted fiber made of glass fiber or the like.

The shape of the flexible member is square! Rectangular and circular.

Any shape such as an ellipse is possible.

If the foam is polyurethane foam, it may be a general-purpose polyether/polyester foam, but it is recommended to use a foam like the one below that is waterproof even if the surface skin layer is torn. preferable. That is, polyurethanes using hydrophobic polyols as raw materials, such as polybutadiene polyurethane and low dimer acid polyurethane t, are preferred.

In addition, even general-purpose polyurethane is mainly composed of a polyether polyol or polyester polyol or an amphiphilic compound obtained by addition-polymerizing 90 mol% or more of an alkylene oxide having 3 or more carbon atoms, and a polyisonanate compound, and further has a melting point or Substances consisting essentially of hydrocarbons with a softening point of 150°C or lower and a boiling point of 200°C or higher at normal pressure (e.g., one or more selected from the group consisting of evaporates, asphalt, oils, petroleum resins, animal and vegetable oils, and dialkyl phthalates) are added. An open-cell polyurethane foam obtained by foaming, comprising: 1. A polyurethane foam having an air permeability of 20 cc/crn2/sec or less at an i 0 U thickness is preferred.

1 in the figure is a water-resistant synthetic resin coated on the uneven surface.

For example, polyethylene resin? This is a coating layer made of silicone resin v-fluororesin, metal, rubber, or the like. This layer prevents rainwater from entering. This layer may be provided not only on the uneven surface but also on the side surfaces or the entire surface as the case may be. Further, an adhesive layer may be further provided on the surface, side surfaces, or upper and lower surfaces of this coating material.

FIG. 3 is a perspective view when filling the gap with the gap filling material of the present invention. 3 indicates the filling material of the present invention +4+5 indicates the roof tile.

That is, after the gap filler 3 of the present invention made of a long material is arranged in the length direction where the gap occurs, the tiles 4 are sequentially stacked and compressed. As shown in FIG. 3, by locating the concavo-convex portions on the sides, they are compressed uniformly and come into close contact with the tiles, thereby preventing the infiltration of rainwater.

In addition, since the gap filler has uneven parts, when compressed, the surface coating layer (1) is folded uniformly without causing local wrinkles, and only the inner surface of the flexible member 2 is folded. It will be compressed, improving durability and making construction easier.

Effects of the Invention The gap filling material of the present invention can be compressed uniformly by simply compressing it, and can be easily filled into gaps between roof tiles with a good appearance.
The uneven surface allows it to come into close contact with tiles, and the uneven surface is covered with a water-resistant coating, improving durability and making it waterproof.

Has a dustproof effect. Further, excellent effects such as being usable even in winter or in cold regions can be achieved.
