〔技術分野〕
この発明は木製枠材の外側に形成した防火目地
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a fireproof joint formed on the outside of a wooden frame material.
従来、防火目地としては、第１図に示すよう
に、無機外装材１，２と木製枠材３で形成される
目地４を金属製目地棒５で覆うようにしたものが
ある。しかし、この金属製目地棒５が目立ちすぎ
て外観上好ましくないという問題がある。
Conventionally, as shown in FIG. 1, there is a fireproof joint in which a joint 4 formed of inorganic exterior materials 1 and 2 and a wooden frame material 3 is covered with a metal joint bar 5. However, there is a problem in that the metal joint bar 5 is too conspicuous and undesirable in terms of appearance.
また、従来他の防火目地として、２枚の外装材

填し、さらに粒状材料と接着剤を介して化粧材料
を塗布したものが提案されている（特開昭52−
036822号公報）。これによれば、目地部分が目立
たないという効果が得られる。しかし、充填材と
して有機質のものを用い、また接着剤も有機材料
であるため、木製枠材の防火性が悪いという問題
点がある。 In addition, as other fire prevention joints, one has been proposed in which an organic filler is filled in a joint formed between two exterior materials and a wooden frame material, and a decorative material is further applied via granular material and adhesive. (Unexamined Japanese Patent Publication No. 1973-
Publication No. 036822). According to this, it is possible to obtain the effect that the joint portion is not noticeable. However, since an organic material is used as the filler and the adhesive is also an organic material, there is a problem that the fire resistance of the wooden frame material is poor.
そこで、目地に充填する充填材と外装材とその
外面の外装塗装との全てに無機材料を用いるもの
を考えた。 Therefore, we considered using inorganic materials for the filler filling the joints, the exterior material, and the exterior coating on the outside.
しかし、無機外装塗装から無機充填材にわたつ

から木製枠材の表面までひび割れが連続すると、
このひび割れ部で耐火性が低下し、木製枠材が燃
え易い。 However, cracks occur from the inorganic exterior coating to the inorganic filler, and the fire resistance decreases in these cracks, causing the inner wooden frame material to catch fire. That is, the inorganic exterior coating and the inorganic filler in the joints may crack due to deterioration over time or due to differences in thermal expansion between various parts during a fire. In particular, inorganic exterior coatings are prone to cracking. Even if these cracks occur individually in the inorganic exterior coating or inorganic filler, if they are not connected to each other, the fire will not spread to the wooden frame material in the event of a fire. However, if the inorganic exterior material and the inorganic filler are in direct contact with each other, cracks are likely to spread to both. In this way, if cracks continue from the outer surface of the inorganic exterior material to the surface of the wooden frame material,
These cracks reduce fire resistance, making the wooden frame material more likely to catch fire.
この発明は、目地が目立たず、木製枠材の防火
性に優れ、特にひび割れを防止してひび割れ部分
で防火性が低下することが防止できる防火目地を
提供することを目的とする。
An object of the present invention is to provide a fireproof joint in which the joint is inconspicuous and has excellent fireproofing properties for a wooden frame material, and in particular can prevent cracking and prevent the fireproofing property from deteriorating at the cracked part.

In the fire prevention joint of the present invention, a groove is formed in the wooden frame material to match the joint formed by two inorganic exterior materials and a wooden frame material, and the groove and the joint are formed to a depth where the entrance portion of the joint remains. is filled with an inorganic filler, the entrance portion of the joint is filled with an organic sealant, and the sealant and the inorganic exterior material are covered with an inorganic exterior coating.

装材と、無機外装塗装と、目地の無機充填材とに

らに、シーリング材で防水性が得られる。 According to the configuration of the present invention, since the inorganic exterior coating is provided to cover the joint sealing material and the inorganic exterior material, the joints are not noticeable and the appearance is good. Furthermore, since inorganic materials are used for the inorganic exterior material, the inorganic exterior coating, and the inorganic filler for the joints, it has good fire resistance. Additionally, the sealant makes it waterproof.

あつても、耐火性を低下させる問題がない。 Moreover, an organic sealant is used between the inorganic exterior coating and the inorganic filler, and this sealant is less prone to cracking than inorganic materials. Therefore, cracks caused in the inorganic exterior coating or the inorganic filler due to aging or overheating are prevented from being transmitted between the two. Therefore, it is possible to alleviate the possibility that the fire resistance of the wooden frame material will deteriorate due to cracks occurring continuously from the inorganic exterior coating to the inorganic filler. Although an organic sealant is used, the surrounding area is entirely covered with inorganic materials such as inorganic exterior paint, inorganic filler, and inorganic exterior material, and the amount of sealant used is small. Therefore, even if the sealant is flammable, there is no problem of lowering the fire resistance.
さらに、木製枠材には目地と合致する溝を設

とができる。 Furthermore, the wooden frame material has grooves that match the joints, and the inorganic filler is filled from the joints to the grooves, so even though some of the joints are filled with sealant, the inorganic filler is thick. This also makes it possible to alleviate cracks and improve fire resistance.

This prevents cracks caused by aging or overheating from propagating between the two. Therefore, it is possible to alleviate the possibility that cracks would occur continuously from the inorganic exterior coating 9 to the inorganic filler 7 and the fire resistance of the wooden frame material 3 would deteriorate. Although organic sealant 8 is used, its surroundings are covered with inorganic exterior paint 9, inorganic filler 7, and inorganic exterior material 2, which are all inorganic materials, and the amount of sealant 8 used is small. Therefore, even if the sealing material 8 is flammable, there is no problem of deterioration of fire resistance.
