本発明は、建築現場又は建築物の壁面工事等に使用する
足場板に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a scaffold board used for construction sites or wall construction of buildings.
従来、この種の足場板は、その素材として鋼製、合板製
又はアルミニウム合金製のものが使用されていた。Conventionally, this type of scaffolding board has been made of steel, plywood, or aluminum alloy.
前記鋼製の足場板は、高所等においても取扱いが容易な
ように比較的薄肉厚の鋼板を用いて構成されているので
、天板の幅方向両側に折返し部を設けて剛性を高めるよ
うにしている。しかしながら、この両側の折返し部では
強度的に充分ではなく、特に足場板は使用時の荷重が中
央部に集中するため、大きな衝撃が加わると中央部が折
損することがあり、これを解決するため全長にわたって
別体の補強を取付けていたが、これは重量が極端に重く
なり、実用性が損なわれ、そして、鋼製の足場板は、腐
食し易く、耐久性に劣るという問題点があった。The above-mentioned steel scaffolding board is constructed using a relatively thin steel plate so that it can be easily handled even in high places. I have to. However, these folded parts on both sides are not strong enough, especially when the scaffold board is in use, the load is concentrated in the center, so if a large impact is applied, the center may break. Separate reinforcements were installed along the entire length, but this added to the extremely heavy weight, impairing practicality, and the steel scaffolding plates were prone to corrosion and had poor durability. .
前記合板製の足場板は、やや軽量化を図れるが、雨水等
にさらされると特に腐り易く、耐久性に劣るのみでなく
１強度が低いという問題点があった。Although the scaffold board made of plywood can be somewhat lightweight, it is particularly prone to rot when exposed to rainwater, etc., and has problems in that it is not only inferior in durability but also has low strength.
前記アルミニウム合金製の足場板は、比較的軽量なもの
が得られるが、前記鋼製の足場板と同様に強度的に充分
でなく、これを防止するため種々の補強をしなければな
らない、また製造に際しては、押出成形により成形しな
ければならないため、その製造のための設備投資費が多
額となり易く、何よりも素材のアルミニウムが鉄よりは
るかに高く、自ずとその製品である足場板が高価格にな
らざるを得ないという問題点があった。Although the aluminum alloy scaffolding board is relatively lightweight, it is not strong enough like the steel scaffolding board, and various reinforcements must be applied to prevent this. When manufacturing, it must be formed by extrusion molding, which tends to require a large amount of capital investment, and above all, the material aluminum is much more expensive than steel, which naturally makes the scaffolding board that is the product expensive. There was a problem that it had to be done.
そこで現場としては軽いアルミニウムの足場板を希望し
ても、最終的には価格面から、腐食し易い鉄や水を吸収
すると重くなる合板の足場板に流れ易かつった。For this reason, although the site requested lightweight aluminum scaffolding boards, in the end, due to price considerations, it was easy to go with steel, which corrodes easily, or plywood scaffolding, which becomes heavy when it absorbs water.
本発明は、上記問題点を解決するもので、低価格且つ量
産可能とし、全く腐食せずに強度が高く軽量化を図るこ
とのできる足場板を提供することを目的とする。The present invention solves the above-mentioned problems, and aims to provide a scaffolding board that can be mass-produced at low cost, has high strength, and is lightweight without corroding at all.
上記目的を達成するための本発明に係る足場板の構成は
、足場板本体が繊維強化プラスチック材料により成形さ
れてなるものである。In order to achieve the above object, the scaffold board according to the present invention has a structure in which the scaffold board main body is molded from a fiber-reinforced plastic material.
次に１本発明の一実施例を図面に基づいて説明する。 Next, one embodiment of the present invention will be described based on the drawings.
