度試験を行った。1. In order to understand the basic performance of the wood-reinforced laminated veneer, a 3 mm thick rotary veneer is dipped in water-soluble phenolic resin solutions for impregnation with different concentrations and then thickened with a hot plate press. 2.0 mm, 1.5 mm, and 1.0 mm (compressibility of 33%, 50%, and 67%, respectively) are heated and compressed to produce wood-reinforced veneers, and promotion of these wood-reinforced veneers. A deterioration test (dimensional stability test against heat and water) and a bending strength test were performed.

いた。Further, the springback sharply decreased as the impregnation rate (weight ratio of the resin solid content to the total dry weight of the veneer) increased. Here, considering springback 5% as the upper limit of the allowable dimensional change of the material, when the compression rate is 67%, the impregnation rate is around 17% or higher, and when the compression rates are 33% and 50%, the impregnation rate is around 25% or higher. , Each of which achieved this condition.

A value of not less than kgf / cm 2 was obtained, and no difference was observed depending on the concentration of the resin liquid. The bending Young's modulus also increases in proportion to the total dry specific gravity of the wood-reinforced single plate, and when the total dry specific gravity is 1.0, a value close to 300 tf / cm 2 is obtained, and when the resin liquid concentration is 15% or less. Although there was no difference depending on the concentration, there was a tendency for the resin liquid concentration to decrease slightly when the concentration was 30%.

合具（以下「木質接合具」という。）を採用することに
より、従来の金属性接合具（金具）による接合と比較し
て、次のような効果が期待できる。1. By adopting a joining tool (hereinafter referred to as "wood joining tool") including a wood joining plate 7, a wood joining pin 10 and a wood gusset 11 formed of a wood-reinforced single-layer laminated material, a conventional metal joining tool ( The following effects can be expected as compared with joining with metal fittings).
【００５７】（１） 建築物の施工性の向上 大型の金具は、重量が大きく、高所の大規模架構上での
取付け作業には施工面での種々の困難を伴うことが多
い。これに対して木質接合具は重量が小さいために取付
け作業は比較的容易に行うことができ、施工性や作業安
全性が大幅に向上する。(1) Improving the workability of buildings Large metal fittings are heavy, and mounting work on a large-scale frame at a high place often involves various difficulties in terms of construction. On the other hand, since the wooden connector has a small weight, the mounting work can be performed relatively easily, and workability and work safety are significantly improved.

となる。このことが、建て上げ後の建造物の初期ガタの
原因となる場合がある。(2) Improvement of pre-drilling and associated problem of initial rattling of buildings In the case of metal fittings, holes to pass bolts and drift pins are separately drilled in members to be joined with metal fittings ( Drilling). At that time, considering the construction error, the diameter of the hole
It is necessary to make a hole larger than the diameter of the bolt to be used. This may cause the initial rattling of the building after it is built.
【００５９】木質接合具にあっては、容易に穿孔できる
ために、軽量化により施工性の向上と相まって、施工時

問題も改善される。Since the wooden connector can be easily pierced, it is possible to integrally pierce with a member to be joined at the time of construction because the weight is reduced and the workability is improved.
Pre-drilling that takes into account construction errors is no longer necessary, and the problem of initial play is improved.
【００６０】（３） 耐火性が優れている 金具が露出している場合は、金属製であるために火災時
の高温により容易に軟化して接合機能を喪失し、建造物
の倒壊の原因となる場合がある。(3) Excellent fire resistance When the metal fittings are exposed, since they are made of metal, they are easily softened by the high temperature at the time of fire and lose their joining function, causing the collapse of the building. May be.

きる。The surface of the wood connector burns in the event of a fire, but the combustion action does not reach the inside due to the action of the carbonized layer formed on the surface. Therefore, assuming a fire in the cross-sectional thickness of the wood connector, and allowing for a suitable burning margin, the bonding function can be maintained well even in a fire.
【００６２】固定用に、ボルトやドリフトピンに代え、
木質接合ピン１０を使用すると、さらに耐火面で有効で
ある。For fixing, instead of bolts and drift pins,
Use of the wood joining pin 10 is more effective in terms of fire resistance.
【００６３】（４） 結露を生じない 同じく金具が露出している場合は、寒冷時に金具の表面
に結露を生じやすく、往々にして接合部分の木部の腐朽
を誘発することがある。(4) No Dew Condensation Similarly, when the metal fitting is exposed, dew condensation is likely to occur on the surface of the metal fitting in cold weather, and this often induces decay of the wood of the joint portion.
【００６４】木質接合具は通常の状態では表面に結露を
生じることはなく、このような問題は解決される。In the normal condition, the wooden connector does not cause dew condensation on the surface, and such a problem is solved.

損なう場合がある。2. Splints and plywood gussets are sometimes used as joints for columns and beams or joints for joints.However, since these joints have low strength, safety is expected to ensure the required joint strength. It is necessary to increase the thickness and area of the cross section, and this may impair the aesthetics of the building, especially where it is visible.

れる。Since the wood connector made of the wood-reinforced single-ply laminated material has greater strength performance than ordinary wood,
It may be much smaller in size than conventional splints or plywood gussets, and such aesthetic problems are considerably improved.

When gluing laminated lumber for large-section structures into an arch type, curved gluing units that have been curved in advance at the factory may be brought into the construction site, but large members are subject to the Road Traffic Law. It may be impossible to carry because of conflict.

る。Then, the straight-through laminated wood which is easy to carry or the curved laminated wood of a size that can be carried is divided and carried in, and the wood connector is used as a connecting medium, and the resorcinol resin adhesive or bolts are used. If drift joints, wood jointing pins, etc. are used together for on-site joining, it will be possible to make on-site production of curved structural laminated wood with the same shape and function as those produced in advance at the factory.

止でき、寸法精度が向上する。4. In the heating / pressing process of the hot plate press, the water content of the resin-impregnated veneer is reduced by performing several breathing steps of decompressing after the completion of pressurization, thus reducing the finished water content of the wood-reinforced veneer laminate ,
It is possible to prevent puncture due to the residual water vapor pressure when decompressing, and improve dimensional accuracy.

A wood reinforced veneer laminated material with a thin metal plate such as aluminum or a reinforcing material inserted such as fiber can improve the strength performance as compared with the case of using only wood and also has excellent workability and durability of the wood reinforced veneer laminated material. It does not impair the dew condensation property, and therefore can be effectively used when high strength is required.
