【考案の詳細な説明】
この考案は、鉄骨旗の耐火被覆保護装置に関す
るものである。[Detailed Description of the Invention] This invention relates to a fireproof covering protection device for a steel flag.
倉庫建物は、柱を鉄骨鉄筋コンクリート造と
し、その梁を純鉄骨造とする場合が多い。このよ
うなむき出しの鉄骨梁は、火災等による高熱を受
けた際、熱変形し、それに起因する建物の一部倒
壊を招く恐れがある。このため鉄骨梁の耐火被覆
としてアスベスト吹付およびアスベスト板粘着等
が行なわれている。 In warehouse buildings, the columns are often made of steel reinforced concrete and the beams are made of pure steel. When such exposed steel beams are exposed to high heat due to a fire or the like, there is a risk that they will be thermally deformed, leading to partial collapse of the building. For this reason, asbestos spraying and asbestos plate adhesion are used as fireproof coatings for steel beams.
従来例えば、前記耐火被覆が施された倉庫にお
いて、フオークリフト等の搬送車を使用する際、
同搬送車がしばしば鉄骨梁脚部に衝突し、その衝
撃によつて耐火被覆の損傷を見ていた。 Conventionally, for example, when using a transport vehicle such as a forklift in a warehouse with the fireproof coating,
The transport vehicle often collided with the steel beam legs, and the impact caused damage to the fireproof coating.
この考案は、前記事情に鑑み創案されたもので
耐火被覆を搬送車等の衝突による損傷から保護し
得る鉄骨梁の耐火被覆保護装置を提供し、前記問
題を解消することを目的とするものである。 This invention was devised in view of the above-mentioned circumstances, and aims to solve the above-mentioned problem by providing a fire-resistant coating protection device for steel beams that can protect the fire-resistant coating from damage caused by collisions with transport vehicles, etc. be.
以下、この考案を図示する実施例に基づき説明
する。 This invention will be explained below based on illustrated embodiments.

石綿吹付けによる耐火被覆３が施され、その下部
フランジ４ｂの下面および前記耐火被覆３の下縁
を覆うようにして耐衝撃性、耐火性の板状の保護
板５が固着されている。 In Fig. 1, there is an upper flange 4a on the surface of the steel beam 2 supporting the upper concrete slab 1.
A fire-resistant coating 3 is applied by spraying asbestos except for the upper surface and the lower surface of the lower flange 4b, and an impact-resistant and fire-resistant plate is applied to cover the lower surface of the lower flange 4b and the lower edge of the fire-resistant coating 3. A protective plate 5 of the shape is fixed.
ところで保護板５はメツシユ筋入りコンクリー
ト板、あるいは無機質フアイバー補強コンクリー
ト板等によつて成型されその取付に際しては接着
剤を使用して接着するか保護板５に設けられた鉄
板と鉄骨梁とを溶接すること等により固定する。 By the way, the protection plate 5 is formed of a mesh reinforced concrete plate or an inorganic fiber reinforced concrete plate, and when it is attached, it is attached using an adhesive or the steel plate provided on the protection plate 5 and the steel beam are welded. Fix it by doing something like this.
この考案は以上の構成からなり、鉄骨梁下部に
耐火性とともに耐衝撃性の保護板を取付けて耐火
被覆を補強しているので損傷を受ける恐れがな
い。またその保護板は予め板状のものを鉄骨梁の
フランジ下面にフランジ下面より耐火被覆厚さだ
け大きくして固定すればよく、石綿吹付けを行な
う場合の定規および受け板の役目をもたらし施工
性が向上する。 This invention has the above-mentioned structure, and since a fireproof and impact-resistant protection plate is attached to the lower part of the steel beam to reinforce the fireproof coating, there is no risk of damage. In addition, the protective plate can be fixed in advance to the lower surface of the flange of the steel beam by making it larger than the lower surface of the flange by the thickness of the fireproof coating, and it serves as a ruler and receiving plate when asbestos spraying is performed, making construction easier. will improve.
