［産業上の利用分野］
本発明は、建物の鉄骨を耐火材で被覆する耐火
被覆工法の改良に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an improvement in a fireproof coating method for covering the steel frame of a building with a fireproof material.
［従来の技術］

維フエルト材を貼付ける工法が開示されている。[Conventional technology] Conventionally, as a fireproof coating method for steel frames, Japanese Patent Application Laid-open No. 57-
No. 197349 and Japanese Unexamined Patent Application Publication No. 1973-112947 disclose a method of pasting fiber felt material.

けることができる、ことなどが挙げられている。 The fireproof coating method described in JP-A No. 57-197349 uses a fiber felt material made of layers of inorganic fibers such as rock wool, ceramic fiber, and glass wool as the fireproof material, and binds the fiber felt material with an inorganic adhesive or This is a method of attaching the fiber felt material to the steel frame using welding pins, and the advantages of using the fiber felt material are that it has excellent performance as a fireproof covering material for the steel frame, can be easily cut with a knife or scissors, and is free from dust. It can be attached without any gaps to the curved or bent parts of the steel frame, it has the effect of absorbing noise and vibration inside the building, and it is lightweight, so there is less load on the steel frame. , and that it can be easily attached with adhesive or welding pins.

よいから、作業性によいことが挙げられている。 The fireproof coating method described in JP-A No. 60-112947 uses a coating material in which cement is dispersed and supported in fiber welt material, which is attached to the steel surface while soaked with water, and shaped by the hardening of the cement. It is a construction method that forms a fireproof coating layer with a constant level of fire resistance, and its effects include that until the fiber felt material is soaked with water, it is relatively lightweight and easy to transport to and from the site. During construction, it is said that it is easy to work because it is only necessary to soak the fiber felt material in water and attach it to the steel surface.
［発明が解決しようとする課題］
しかし、前者の工法で使用する繊維フエルト材

ら、鉄骨の屈曲部、角度、曲面部に対する屈曲性
が良いといつても完全なものではない。また、取
り扱い中、あるいは切断時に多少の粉塵を発生す
る。[Problem to be solved by the invention] However, since the fiber felt material used in the former construction method is made by hardening fibers in layers, it has good flexibility against bends, angles, and curved surfaces of the steel frame. It's not always perfect. Also, some dust is generated during handling or cutting.
また、後者の工法は、バインダーとしてセメン

内部にまでセメントを均一に分散させることは非
常に難しく、被覆層はセメントの硬化により形成
は一定したものとなるが、強固な成形体とはなら
ない。 In addition, in the latter method, cement is used as a binder, and the cement is dispersed and supported in the fiber felt material in a powder state, so it is extremely difficult to uniformly disperse the cement inside the fiber felt material, and the coating layer Although the formation becomes constant as the cement hardens, it does not result in a strong molded body.
また、繊維層内に単に分散状態に置かれている
セメントは、繊維フエルト材の輸送時や取り扱い
中に脱落するので、施工後の被覆層の強度低下を
招くばかりでなく、施工現場にて水を含ませるた
め、被覆層の物性が現場での作業条件に影響され
易いという欠点がある。 In addition, cement that is simply dispersed within the fiber layer falls off during transportation or handling of the fiber felt material, which not only reduces the strength of the coating layer after construction, but also causes water to leak at the construction site. The disadvantage is that the physical properties of the coating layer are easily influenced by on-site working conditions.
［発明の目的］
