いて、符号４で表示される部分は接着剤層である。A gypsum board composite, which is a laminate of a sheet-like thermosetting resin foam layer and a gypsum board, is a gypsum board with reinforcing paper as shown by reference numeral 1 in FIG. 2, that is, a gypsum board 2.
A gypsum board 1 with reinforcing paper 3 pasted on the upper surface, lower surface, and both sides in the longitudinal direction is 50 to 608C.
Then, a thermosetting foaming resin liquid is supplied to the upper surface of the gypsum board with reinforcing paper 1, and if necessary, non-woven fabric, metal foil 2 and synthetic resin are applied to the two sides of the foaming resin liquid. By supplying a surface material such as a film and heating it between two upper and lower steel endless belt conveyors in a heat curing furnace, the thermosetting foamable resin is foamed and hardened to form a sheet. It was obtained by forming a thermosetting resin foam layer and then cutting it into a predetermined size. In addition, in the reinforced paper-covered gypsum board 1 shown in FIG. 2, the portion indicated by the reference numeral 4 is an adhesive layer.

ード複合体の製造方法が利用されている。For this reason, as shown in FIG. 3, the lower stage made of steel has side seal belts 5, 5 made of rubber or soft plastic with an inverted-shaped cross section and an inverted-shaped cross section that are in contact with or fixed to both edges in the longitudinal direction. A method for manufacturing a gypsum board composite in which leakage of the aforementioned thermosetting resin liquid is prevented by using an endless belt conveyor 6, i.e. a rubber (for example, S
General rubber such as BR, heat-resistant rubber such as fluororesin, reinforced rubber reinforced with nylon fiber or glass fiber, etc.)! f. The lower end endless belt conveyor 6 (7) in which the side seal belt 5 made of soft plastic is made of steel.
The gypsum board 8 with reinforcing paper is placed on the lower endless belt conveyor 6 with side seal belts 5 that are in contact with or fixed to both edges in the longitudinal direction, and then thermosetting foam is applied to the top surface of the gypsum board 8. After supplying the foamable resin liquid 9 and, if necessary, supplying a face material 10 on the upper surface of the foamable resin liquid 9, the upper endless belt conveyor 11 is further brought into contact with the foamable resin liquid 9, and the foaming resin liquid 9 is passed through a heating curing furnace. A method for manufacturing a gypsum board composite is used in which the thermosetting foamable resin is foamed and hardened.
ところで、前記従来のサイドシールベルト付きの下段エ
ンドレスベルトコンベヤーヲ使用する石膏ボード複合体
の製造方法においては、サイドシールベルトの寸法精度
、経時寸法変化。By the way, in the method of manufacturing a gypsum board composite using the conventional lower endless belt conveyor with side seal belts, the dimensional accuracy of the side seal belts and dimensional changes over time are limited.
更には蛇行等が原因で、石膏ボードの上面に供給した熱

悪い石膏ボード複合体が得られ易いという欠点を有して
いる。Furthermore, due to meandering, etc., it is impossible to completely seal the thermosetting foaming resin liquid supplied to the top surface of the gypsum board, and the end of the gypsum board still has stains in the longitudinal direction, making the gypsum board composite This has the disadvantage that a gypsum board composite tends to have poor adhesion at the abutting portions when they are brought into contact during construction.

う経費アップが生ずるという欠点を有している。Therefore, in order to eliminate the leakage of the foaming resin liquid from the gap between the side seal belt and the gypsum board, a gap between the side seal belt and the gypsum board and between the side seal belt and the resulting thermosetting resin foam layer is required. A method of contacting a series of synthetic resin films between the two is considered, but not only is it still not possible to completely eliminate the leakage of the foaming resin liquid, but the synthetic resin film in contact is consumed. This method has the disadvantage of increasing costs.

面との間に漏れるのを防止するものである。The method for manufacturing a gypsum board composite of the present invention is such that the reinforcing paper attached to the top surface of the gypsum board has extending portions protruding from both edges in the longitudinal direction of the top surface of the gypsum board. The gypsum board with reinforcing paper is in contact with or is fixed to the gypsum board with reinforcement paper, and side seal belts made of rubber or soft plastic having an inverted cross section and an inverted cross section are in contact with or are fixed to both edges of the belt conveyor in the longitudinal direction. By placing the reinforcing paper on the lower endless belt conveyor so that the extending portion of the reinforcing paper affixed to the upper surface of the gypsum board is in contact with the upper surface of the mutually opposing inner step portion of the side seal belt. This prevents the thermosetting foamable resin liquid supplied to the upper surface of the gypsum board from leaking between the side seal belt and the side surface in the longitudinal direction of the gypsum board.
