Furthermore, the present invention relates to a molded article of a wood preservative to be placed in wood.

が生ずる。 It is known to preserve wooden structures by impregnating the wood with wood preservatives such as metal salts or creosote, but this method becomes less effective over time, and the lack of preservatives is primarily due to moisture loss. , appears in areas where raindrops or condensate tend to collect. For example, in the case of railway sleepers, several years after the sleepers are installed, corrosion or decay occurs at the bottom of the substrate that holds the rails.

がその他の防腐剤から形成されない。 According to the present invention, a method is provided for preserving wood from rot that is likely to occur due to moisture by inserting a wood preservative into the pores of the wood. A molten wood preservative, which is solid at room temperature, is used for insertion. A preferred wood preservative that makes up at least the majority of the melt used in this invention is boron oxide. Boron oxide (B 2 O 3 ) itself is glassy,
That is, it is a molten substance, but it can be used as a powder, usually in the form of discrete particles. The injection material element according to the invention is generally in molten form. That is, it is formed from discrete particles of boron oxide (which is fused) or a single element but no other preservative.

Moisture in wood placed outdoors dissolves rapidly, whereas molten fillers dissolve more slowly and therefore may provide protection for longer periods of time. The life of other particulate wood preservatives can be similarly extended by bringing them into the molten state.

These materials are either melted with the boron oxide or incorporated as discrete particles in a molten matrix of boron oxide. These usually contain small amounts of metal oxides that have one or both of the following effects:

を用いることが好ましい。 The melt according to the invention is formed as a plug or filler to match the shape of the hole drilled in the wood. The most preferred form of this plug is a rod or cylinder, for example, a round rod whose overall length is greater than its maximum width, and other forms include a lump, a pellet, and a pellet. These preformed elements are formed by extruding a molten wood preservative and by compression molding particulate material in a mold which is heated and melted into a unitary structure. Preferably, boron oxide is used to melt the particulate material.
この要素を孔中に挿入したのち、水分が直接入
らないように蓋によつて孔部を覆う。鉄道の枕木
を例にとつて以下に述べるように、1以上の成形
体を挿入しうる。 After the element is inserted into the hole, the hole is covered with a lid to prevent direct moisture from entering. One or more shaped bodies can be inserted, as described below using the example of railway sleepers.

いて形成される。 Preferably, a plurality of holes are formed and each hole is filled with at least one melt. For example, in the case of a railroad sleeper with a square base plate, two holes may be provided on each side of the base plate, with the holes facing downward into the sleeper and inward toward the center of the base plate. Ru.
本発明による溶融体は従来の木材防腐剤よりも
多くの利点を有する。本発明の挿入体は溶融状態
にあるので、詰め物の密度が高く、したがつて、
木材防腐剤の所定重量による容積が粒状材料より
も小である。このため、詰め物が置かれる孔部が
小さく形成でき、木材の機械的強度を低下させる
おそれがない。小さい孔は大きい孔よりも速く、
安価に形成できる。また、溶融体は、粒状体より
も木材中の湿分による溶解の速度が遅いが、他方
では、菌類が発生しやすい木材の部分に所望の濃
度の殺菌剤を維持しうるように溶解する。 The melt according to the invention has many advantages over conventional wood preservatives. Since the insert of the present invention is in a molten state, the filling is dense and therefore
The volume by weight of the wood preservative is smaller than that of the particulate material. Therefore, the hole in which the stuffing is placed can be formed small, and there is no risk of reducing the mechanical strength of the wood. Small holes are faster than large holes,
Can be formed inexpensively. The molten material also dissolves more slowly than the granular material due to moisture in the wood, but on the other hand, it dissolves in a manner that maintains the desired concentration of fungicide in areas of the wood that are susceptible to fungus growth.
酸化硼素は、それ自体が活性成分である硼酸を
生成するように木材中の水分に溶解する。硼酸
は、木材中に含まれる自由水の量により定められ
る割合で木材中に拡散する。即ち木材の湿度が高
い程、木材中での防腐剤の移動が速くなる。溶融
した酸化硼素1mlは、3mlの硼酸を生成する。 Boron oxide dissolves in the moisture in the wood to produce boric acid, which itself is the active ingredient. Boric acid diffuses into the wood at a rate determined by the amount of free water contained in the wood. That is, the higher the humidity of the wood, the faster the preservative will move through the wood. 1 ml of molten boron oxide produces 3 ml of boric acid.
シリカを混入することにより酸化硼素プラグの
溶解速度が遅くなりプラグの寿命を延長させう
る。ペースト状の硼酸が5年間、使用できる場
合、本発明によるプラグは12ないし15年間使用可
能である。 By incorporating silica, the dissolution rate of the boron oxide plug can be slowed down and the life of the plug can be extended. If pasty boric acid can be used for 5 years, the plug according to the invention can be used for 12 to 15 years.
木材防腐剤の所要重量が小さいため、溶融プラ
グを入れるための孔部を小さく形成することがで
き、このため木材に機械的損傷および劣化を与え
ることが少ない。 Due to the low weight requirement of the wood preservative, the holes for the molten plugs can be made smaller, thereby causing less mechanical damage and deterioration to the wood.
もし本発明の溶融体中に、酸化硼素よりも溶解
性の高い木材防腐剤を酸化硼素とともに用いるな
らば、溶解性の低い酸化硼素中に埋め込まれてい
るため拡散速度は緩慢である。 If a wood preservative that is more soluble than boron oxide is used in the melt of the present invention, the rate of diffusion will be slow because it is embedded in the less soluble boron oxide.
本発明の好ましい態様は、以下の実施例に述べ
るように、防腐剤は木材中にあらかじめあけた棒
状の孔部に挿入される均質成分の棒状体である。 In a preferred embodiment of the present invention, as described in the examples below, the preservative is a homogeneous rod-shaped body inserted into a rod-shaped hole previously drilled in the wood.
この防腐剤プラグを木材中に挿入したのちプラ
スチツク又は他の適切な材料の蓋部材で密閉す
る。防腐剤が木材中に拡散しつくしたときは、蓋
を取り外して、孔部中に新しいプラグを挿入する
だけでよい。 The preservative plug is inserted into the wood and sealed with a closure of plastic or other suitable material. When the preservative has diffused into the wood, simply remove the lid and insert a new plug into the hole.
以下において本発明の実施例を、鉄道の枕木を
例に説明するが、本発明はのちに述べるその他の
木材構造物に適用可能である。 Embodiments of the present invention will be described below using railway sleepers as an example, but the present invention is applicable to other wooden structures that will be described later.
ほとんど使用されない軌道上の枕木の寿命は数
10年とされているが、枕木を使用可能な状態に置
く場合、ほとんどの枕木に、約10ないし15年後に
木材防腐剤を施す必要がある。 The lifespan of railway sleepers, which are rarely used, is several
Although it is said to last for 10 years, most sleepers need to be treated with a wood preservative after about 10 to 15 years if they are to be kept in a usable condition.
鉄道の枕木の腐朽は、軌道の基板の周囲部から
始まる。とくに、基板を枕木に固定するねじ孔の
近くの部分に生ずる。 Decay of railway sleepers begins at the periphery of the track base. This occurs especially near the screw holes that secure the board to the railroad ties.
鉄道の枕木に用いるための本発明による代表的
なプラグは、長さが80mm、直径が12mmの円筒形に
形成される。この重さは約16gである。 A typical plug according to the invention for use in a railway sleeper is formed into a cylindrical shape with a length of 80 mm and a diameter of 12 mm. This weight is approximately 16g.

なる。 Typically, eight holes, two on each side of each rectangular board, are formed to a depth less than half the thickness of the sleeper. Each hole is just wide enough to receive a plug and is angled downwardly toward a position below the center of the substrate as shown. Each hole is
The wood preservative is drilled into the lower part of the board so that it can be applied directly to the areas most susceptible to decay. This area also protects water-soluble preservatives from soaking in water if the sleeper is placed in an area prone to heavy rain. Because water condenses at the bottom of the substrate, the bottom of the substrate contains the most moisture, which facilitates the diffusion of wood preservatives from the sleepers.

が、溶融化プラグはその位置で安定される。 A plug according to the invention is inserted into each hole and the hole is covered with a lid. If the holes are drilled to a length exceeding 150-200 mm, which is required if the holes are formed at a sharp slope from the vertical direction, two or three short rods may be used in each hole. . Powdered inserts or paste wood preservatives are susceptible to compaction by the pressure transmitted from the wood sleepers as the train passes, whereas the fused plugs are stabilized in position.
本発明の溶融体の別の利点は、これが少なくと

For use in railway sleepers, round bars with a mass of 10 to 100 grams are suitable. For use in window frames and doors, round bars with a mass in the range of 1 to 10 grams are suitable, for example a round bar with a weight of 2 to 2.5 grams, a length of 18 mm and a diameter of 9 mm. Used appropriately.
