本発明は軽量サンドイッチ構造体を形成する複合建築材
に関する。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to composite building materials forming lightweight sandwich structures.
複合建築材を構成するサンドイッチ構造体、特にハニカ
ム心材を用いたものは軽量であり、圧縮強度が強く広く
用いられる。Sandwich structures constituting composite building materials, especially those using honeycomb core materials, are lightweight and have high compressive strength, and are widely used.
しかしながら、このようなサンドイッチ構造体はハニカ
ム心材と表面材との接着面積が少なく接着力が弱く、引
張り強度に対して弱く、また曲げ強度も弱いという問題
点を有する。However, such a sandwich structure has problems in that the adhesion area between the honeycomb core material and the surface material is small, the adhesive strength is weak, the tensile strength is low, and the bending strength is also low.
又吸音、断熱効果を向上することを目的として、ハニカ

は充填材の表面を表面板に接着固定する。この場合充填
材はハニカム心材と表面板との接着強度に寄与しない、
したがって、従来と同様の問題点を残している。In addition, for the purpose of improving sound absorption and heat insulation effects, it has already been proposed that the cell voids of a honeycomb core material are filled with fillers such as organic or inorganic foam particles or fiber materials (Japanese Utility Model Publication No. 44-23165). After the filling material is filled into the cell voids of the honeycomb core material, an adhesive is sprayed onto both sides of the filling material to adhesively fix the surface of the filling material to the surface plate. In this case, the filler does not contribute to the adhesive strength between the honeycomb core and the surface plate.
Therefore, the same problems as before remain.
また、ハニカム心材として心材自身を部分的に補強する
目的で必要個所に凹段部を形成、凹断面硬質発泡樹脂を
流し込んで後プレス発泡させ硬質発泡樹脂を充填するも
のも既に提案されている。In addition, a honeycomb core material has already been proposed in which concave steps are formed at necessary locations for the purpose of partially reinforcing the core material itself, and a concave cross-section hard foam resin is poured into the honeycomb core material, followed by press foaming and filling with the hard foam resin.
（実公昭５７−４５１６２）
この提案においては、ハニカム心材自体の部分的な補強
目的は達成されるが複合建築材における表面材とハニカ
ム心材との接着強度は強化されない。(Utility Model Publication No. 57-45162) In this proposal, the purpose of partially reinforcing the honeycomb core material itself is achieved, but the adhesive strength between the surface material and the honeycomb core material in the composite building material is not strengthened.

次に他方の表面板１の裏面に接着剤を塗布する、この表
面板１を接着剤面がハニカム心材２と接するように載置
する。Next, an adhesive is applied to the back surface of the other surface plate 1, and this surface plate 1 is placed so that the adhesive surface is in contact with the honeycomb core material 2.
フオームプラスチック原体は接着剤の硬化温度より高い
温度で発泡するものを選択することが好ましい。It is preferable to select a foam plastic material that foams at a temperature higher than the curing temperature of the adhesive.

ク原体３が発泡し、その発泡圧によってセル壁を変形し
てしまいハニカム心材２のもつ本来の圧縮強度を低下し
てしまうためである。This is because, during the next process of hot pressing, the foam plastic material 3 foams before the surface plate 1 and the honeycomb core material 2 are hardened and bonded, and the foaming pressure deforms the cell walls, causing the honeycomb core material 2 to This is because the original compressive strength it has is reduced.

で充填するとともに表面板裏面との接着を行なう。The sandwich laminate composed of the surface plates 1 and 1 and the honeycomb core material 2 is inserted into a hot press and heat-pressed, and the adhesive hardens to bond the surface material and the honeycomb core material, and the cell voids of the honeycomb core material are formed. The foam plastic material inside is foamed, the void is filled with the foam plastic material, and the foam plastic material is bonded to the back surface of the top plate.
また製造方法においてハニカム心材両面に接着剤を塗布
し５表面板に載置戸フオームプラスチック原体の挿入、
更に表面板を蔵置後に熱圧締しても行なえる。In addition, in the manufacturing method, adhesive is applied to both sides of the honeycomb core material, and the mounting door form plastic material is inserted into the 5-face plate.
Furthermore, this can also be done by hot pressing the surface plate after storage.

が同時になされ生産性が向上する。By putting the foam plastic material into the cell voids of the honeycomb core material and heat-pressing it, the adhesion between the honeycomb core material and the top plate, the foaming of the material, and the adhesion to the cell wall surface board are achieved simultaneously, improving productivity. do.

て、表面板とハニカム心材との 接着面積が少なくな
るため接着力が弱く、かつ、引張り強度が弱い、曲げ強
度が弱いという従来の問題点を解決できた。- Since the foam plastic is foamed inside the cell gap, it is simultaneously filled into the cell gap and adhered to the cell wall and surface plate, achieving complete integration. Therefore, the conventional problems of weak adhesive strength, low tensile strength, and low bending strength due to the reduced bonding area between the surface plate and the honeycomb core material could be solved.

ため、ハニカム心材２はセル壁を破壊されることなく本
来の強度を保持できる。- Since a foam plastic material whose foaming temperature is higher than the curing temperature of the adhesive is used, the adhesive hardens before the foam plastic material foams when heat-pressed. Therefore, the honeycomb core material 2 can maintain its original strength without destroying the cell walls.
■ 断熱、吸音性も向上する。■ Improved insulation and sound absorption properties.

着剤を裏面に塗布された表面板を載置する。Styrene beads (expansion ratio: 60 times) with a particle size of 2 cm, obtained by mixing polystyrene with a foaming agent, are inserted into the cell voids of the Al honeycomb. Furthermore, a top plate whose back surface is coated with the same adhesive as before is placed on top of it.

材が容易に得られた。The laminate is inserted into a hot press and heat-pressed at 120°C for 5 minutes to harden the adhesive and foam the styrene beads.) In this way, the surface plate, honeycomb core, and core cell voids are filled. By integrating the styrene foam, a lightweight composite building material with improved strength and excellent sound absorption and heat insulation properties was easily obtained.
