Description
【発明の詳細な説明】 本発明は金属補強合成木材の製造方法に関する。[Detailed description of the invention] The present invention relates to a method for producing metal-reinforced synthetic wood.
従来木材は建材はかりでなく冷凍車、トラック、コンテ
ナ等の荷台、建築現場における足場板として広く一般に
用いられている。ところで、木材を冷凍車の荷台として
用いる場合には、その湿気により＋ｔ；Ｉｌり易く、寿
命が短かいという問題があった。Traditionally, wood has been widely used not only as building material scales but also as loading platforms for refrigerated cars, trucks, containers, etc., and as scaffolding boards at construction sites. By the way, when wood is used as a loading platform for a refrigerated vehicle, there is a problem in that it tends to rot due to moisture and has a short lifespan.
また、荷台として用いる場合には毛羽立ちや木目により
商品を傷つけたり、さらに足場板として用いる場合には
強度に問題があった。In addition, when used as a loading platform, the product may be damaged due to fuzz and wood grain, and when used as a scaffolding board, there are problems with strength.
また、最近ＦＲＰ （ガラス繊維強化グラスチ、り）を
用いた合成木材が提案されているが、このＦＲＰ全用い
た合成木材は高価−であるという欠点がある。Furthermore, synthetic wood using FRP (glass fiber reinforced glass) has recently been proposed, but this synthetic wood made entirely of FRP has the drawback of being expensive.
本発明は上記実１ｉ！７に始みてなされたもので、湿気

いることができる。The metal-reinforced synthetic wood of the present invention is produced by housing the metal bodies assembled as ribs in a mold of a molding machine, injecting a synthetic resin raw material into the mold, and performing reaction injection molding in the core mold. Ru. Here, as the synthetic resin raw materials, polyols and incyanates for forming polyurethane foams can be used.

This is the older brother of Kozu ω・11′. This frame is made up of 4 pieces, consisting of 5 horizontal members 1 and 2 vertical members 2 that reinforce the yellow wood at both ends. Grooves corresponding to the board width and thickness of the l'i vertical frame 2 are formed at both ends of each horizontal member 1, and the vertical members 2 fit into the grooves of each borrowed material 1, and each horizontal member 1 The horizontal members 1 are reinforced in a sandwiching manner, and the quality of both the horizontal members 1 and the vertical members 2 is high carbon steel, which is carbon 1 special steel.

In this case, holes corresponding to the plate width and plate thickness of the vertical members 20 are formed at both ends of each horizontal member 10, and the vertical members 20 are aligned with the holes of the +f and l members 10 ILQ, and the horizontal members 20 are 10 is reinforced.

may be completed. However, in this case, the bolt hole is
It is preferable to make the diameter of the delt sufficiently larger than the diameter of the delt used so that the diameter of the delt is not exposed. These girth holes can be formed in the same manner in the structure shown in FIG.

To support. This can prevent the skeleton from being exposed from the urethane synthetic resin after reaction injection molding of the urethane synthetic resin in the mold described later, and the hole 11 can also be used as a bolt hole after molding. can.

る。Once the framework is assembled into the mold, a synthetic resin raw material that corrugates the framework is then injected into the mold. In this example, since polyurethane foam is used as the synthetic resin, polyol and isocyanate are used as the injection raw materials, and polyaddition reaction, foaming reaction, and crosslinking reaction are performed from these raw materials lO in the mold. The resulting cured polyurethane foam covers the skeleton.

This framework is encapsulated by polyurethane foam 30. That is, the entire upper surface of the metal-reinforced synthetic wood is made of polyurethane foam 30 and has a plate shape of a predetermined thickness, and a cavity S is formed between the ribs on the lower surface. This cavity S has the advantage of improving ventilation and draining water.

いため、合成木材には破壊がみられなかった。As is clear from Table 1, there is a proportional relationship between the iii artificial nail and the deflection up to a load of 900 Ky, and when #3K exceeds this, the proportional relationship breaks down. This shows that the elastic limit is around a load of 950K9.However, since this Amstra testing machine can only test up to 1 ton, no breakage was observed in the synthetic wood.

Destruction was seen on JR 341.
すなわち、上記金属補強ウレタン合成木材とアビトン板
