以下、本発明のアンカー受圧板の製造方法について、図面を参照しつつ説明する。
図１〜７は、本発明に係るアンカー受圧板の製造方法について一連の工程を例示する説明図である。図中における符号１はプレス成形型の下型、符号２はプレス成形型の筒型、符号３はプレス成形型の上型、符号４はプラスチック廃材の粉砕物を含有する樹脂材料、符号５はＦＲＰ、符号６はエジェクターである。
尚、上記プレス型はアンカー受圧板を上下逆転して成形するようになっているので、下型１はアンカー受圧板の上面及び斜面に対応し、上面に相当する部分１１及び斜面に相当する部分１２，１２を有している。また、上型３はアンカー受圧板の下面に対応している。 Hereinafter, the manufacturing method of the anchor pressure receiving plate of this invention is demonstrated, referring drawings.
FIGS. 1-7 is explanatory drawing which illustrates a series of processes about the manufacturing method of the anchor pressure receiving plate which concerns on this invention. In the figure, reference numeral 1 is a lower mold of the press mold, reference numeral 2 is a cylinder of the press mold, reference numeral 3 is an upper mold of the press mold, reference numeral 4 is a resin material containing a pulverized plastic waste, and reference numeral 5 is FRP, code 6 is an ejector.
Since the press die is formed by turning the anchor pressure plate upside down, the lower die 1 corresponds to the upper surface and the inclined surface of the anchor pressure plate, and the portion 11 corresponding to the upper surface and the portion corresponding to the inclined surface. 12 and 12. The upper die 3 corresponds to the lower surface of the anchor pressure receiving plate.

以下本発明に係るアンカー受圧板の製造方法の一例について工程を追って説明する。
先ず第１の工程として、図１に示す上面に相当する部分１１にＦＲＰ５を３プライ（ハンドレイアップで３層）形成し、必要に応じて金属板（図示せず）を積層する。この場合、上記ＦＲＰ５は、図示するように上面に相当する部分１１のみならず、斜面１２及び側面１５に相当する部分にも形成すると、得られるアンカー受圧板の強度が向上する点で好ましい。また、ＦＲＰ５をハンドレイアップする前に、予め下型内の表面にゲルコートを施しておくと、表面の外観が向上する点で好ましい。 Hereinafter, an example of a method for manufacturing an anchor pressure receiving plate according to the present invention will be described in the order of steps.
First, as a first step, three plies (three layers by hand layup) of FRP 5 are formed on a portion 11 corresponding to the upper surface shown in FIG. 1, and a metal plate (not shown) is laminated as necessary. In this case, it is preferable that the FRP 5 is formed not only in the portion 11 corresponding to the upper surface as shown in the figure but also in the portions corresponding to the inclined surface 12 and the side surface 15 in that the strength of the obtained anchor pressure receiving plate is improved. Further, it is preferable to apply a gel coat to the surface in the lower mold in advance before the hand laying up of the FRP 5 in terms of improving the appearance of the surface.

上記金属板の形状としては、例えば図１０〜１２のアンカー受圧板に例示するようなリブ付き鉄板２０や平鉄板２１の形状など適宜の形状のものを用いることができる。   As the shape of the metal plate, for example, an appropriate shape such as the shape of the ribbed iron plate 20 or the flat iron plate 21 as exemplified in the anchor pressure receiving plate of FIGS.

次に、第２の工程として、図２に示すようにプラスチック廃材の粉砕物を含有する樹脂材料４を充填して図３に示すように上型３を用いてプレス成形してＦＲＰと一体化する。この場合、プレス圧力は、特に限定されないが、通常２〜５ＭＰａとされる。また、図８に示すように、プレスする際に上型３を押さえるために用いるプレス板１６のサイズは、必ずしも上型３と同じである必要はなく、上型３より小さなサイズであってもよい、この場合、プレス後の養生時に押さえ１７を用いると、上型３が固定され安定して養生することができる点で好ましい。   Next, as a second step, as shown in FIG. 2, the resin material 4 containing the pulverized plastic waste material is filled and press-molded using the upper die 3 as shown in FIG. 3 to be integrated with the FRP. To do. In this case, the press pressure is not particularly limited, but is usually 2 to 5 MPa. Further, as shown in FIG. 8, the size of the press plate 16 used for pressing the upper die 3 during pressing is not necessarily the same as that of the upper die 3, and may be smaller than the upper die 3. In this case, it is preferable to use the presser 17 during curing after pressing because the upper mold 3 can be fixed and stably cured.

上記プレス後の養生条件としては、特に限定されないが、上記樹脂材料４がウレタン樹脂などの熱硬化性材料を含有する場合には、硬化反応を促進するため、例えば図８（ｂ）に例示するように、下型１の上面に相当する部分１１や斜面１２に相当する部分及び上型３の内部に加熱ヒーター１８を設けることが好ましい。   The curing conditions after the pressing are not particularly limited. However, when the resin material 4 contains a thermosetting material such as a urethane resin, the curing reaction is promoted, for example, as illustrated in FIG. As described above, it is preferable to provide the heater 18 in the portion 11 corresponding to the upper surface of the lower die 1, the portion corresponding to the inclined surface 12, and the inside of the upper die 3.

また、筒型２は、図８（ｂ）に示すように、下型１の側面部１５表面より内側にＦＲＰ５の厚さに相当する分だけ突出させて設置されると、上型３を押し下げる際にＦＲＰ５を引っ掛けることを防止できる点で好ましい。   Further, as shown in FIG. 8B, when the cylindrical mold 2 is installed so as to protrude from the surface of the side surface portion 15 of the lower mold 1 by an amount corresponding to the thickness of the FRP 5, the upper mold 3 is pushed down. At this time, it is preferable in that FRP 5 can be prevented from being caught.

次に、第３の工程として、図４に示すように、樹脂材料４の上面に相当する部分がＦＲＰ５で補強された成形物を脱型し、図５に示すように成形物の下面に相当する部分にＦＲＰ１３を３プライ（ハンドレイアップで３層）積層する。上記脱型時には、脱型を容易にするために、図４に示すようにエジェクター６，６が用いられることが好ましい。   Next, as a third step, as shown in FIG. 4, the molded product in which the portion corresponding to the upper surface of the resin material 4 is reinforced with FRP 5 is removed, and as shown in FIG. 5, it corresponds to the lower surface of the molded product. 3 layers of FRP13 (3 layers by hand layup) are laminated on the part to be processed. At the time of demolding, in order to facilitate demolding, it is preferable to use ejectors 6 and 6 as shown in FIG.

得られた成形物は図６に示すように適宜の形状でアンカー挿通孔１９が穿孔されアンカー受圧板が得られる。また、本発明のアンカー受圧板は図７に示すように、必要に応じて、下面部に相当する側のＦＲＰ１３に接して更に発泡体１４が貼り付けられ積層されたものであってもよい。この場合、得られるアンカー受圧板の軽量性が向上する点で好ましい。   As shown in FIG. 6, the obtained molded product has an anchor insertion hole 19 having an appropriate shape to obtain an anchor pressure receiving plate. Further, as shown in FIG. 7, the anchor pressure receiving plate of the present invention may be a laminate in which a foam 14 is further adhered and laminated in contact with the FRP 13 on the side corresponding to the lower surface portion, as necessary. In this case, it is preferable at the point which the lightweight property of the anchor pressure-receiving plate obtained improves.

また、上面部の強度を補強するために、例えば図９に示すように、支持鉄板２３で上面２６が補強されたものであってもよい。   Moreover, in order to reinforce the intensity | strength of an upper surface part, as shown, for example in FIG. 9, the upper surface 26 may be reinforced with the support iron plate 23. FIG.

更に、本発明のアンカー受圧板は図１２に例示するように、外表面が弾性樹脂２４で被覆されたものであってもよい。弾性樹脂２４で被覆されることにより、施工時の変形に対して弾性樹脂２４が追従し易く、上面や斜面など外表面の凹み等が発生し難くなり外観を向上することができる。   Furthermore, the anchor pressure receiving plate of the present invention may have an outer surface coated with an elastic resin 24 as illustrated in FIG. By covering with the elastic resin 24, the elastic resin 24 can easily follow the deformation at the time of construction, and the outer surface such as the upper surface and the inclined surface is less likely to be generated and the appearance can be improved.

本発明のアンカー受圧板及びその製造方法によれば、プラスチックの廃材を多量に用いることが可能となり、軽量性と経済性を兼ね備えたアンカー受圧板を提供することができ、プレス成形により成形することが出来るので、成形時に廃材が発生し難く、成形が容易なアンカー受圧板及びその製造方法を提供することができる。   According to the anchor pressure plate and the manufacturing method thereof of the present invention, it is possible to use a large amount of plastic waste material, and it is possible to provide an anchor pressure plate having both light weight and economy, and molding by press molding. Therefore, it is possible to provide an anchor pressure receiving plate that is less likely to generate waste during molding and can be easily molded, and a method for manufacturing the anchor pressure receiving plate.

このため、廃棄物のリサイクルが容易となり、環境に対する負荷低減に貢献することができる。   For this reason, it becomes easy to recycle waste, and it can contribute to the reduction of the burden on the environment.
