（産業上の利用分野）
本発明は、建物の床部骨を構成する床板材の目地構造に
関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a joint structure of floorboard materials that constitute the floor bones of buildings.
（従来の技術）
従来の板材の目地構造としては、例えば、実公昭６３−
９６８９号公報等に記載されているようなものが知られ
ている。(Prior art) As a conventional joint structure of plate materials, for example,
The one described in Japanese Patent No. 9689 and the like is known.

造となっていた。In this conventional structure, recesses are formed on mutually opposing side surfaces of adjacent plate materials, and a sealing material is provided in each recess along the inner surface shape of the recess. The plates were joined with the sealing materials butted against each other, and the refractory material was provided in the gap formed between the sealing materials.
（発明が解決しようとする課題）
ところで、このような従来の目地構造を有する板材を床

の目地構造にあっては、耐火材がシール材によ・って上
下から挟まれているので、火災発生時には最初に耐火材
より下側に位置するシール材が燃焼する可能性が高い。(Problems to be Solved by the Invention) By the way, when a board material having such a conventional joint structure is used as a floor board material, the refractory material will be sandwiched from above and below by the sealing material. In addition, since flames burn upward, floorboard materials are almost always exposed to fire from the bottom when a fire occurs on a lower floor. However, in such a conventional joint structure, the fireproofing material is sandwiched between the sealing material from above and below, so in the event of a fire, the sealing material located below the fireproofing material will burn first. Probability is high.
従って、火災が小火で済んだとしても、シール材が燃焼
することにより防水機能が半減するという問題があった
。Therefore, even if the fire is a small flame, there is a problem in that the sealing material burns and the waterproof function is reduced by half.
本発明は上記のような問題に着目し、耐火材によってシ
ール材を完全に保護し、小火発生後もシ−ル材の防水機
能が低下することのない床板材の目地構造を提供するこ
とを目的としている。The present invention has focused on the above-mentioned problems, and provides a joint structure for floorboard materials in which the sealing material is completely protected by a fireproof material, and the waterproof function of the sealing material does not deteriorate even after a small fire occurs. It is an object.
