Description of the Related Art Conventionally, a free access floor board has been used which is laid on a floor surface of a building at regular intervals in order to carry out wiring and piping of office equipment or underfloor air conditioning. For this type of floor board, in order to ensure sufficient load bearing capacity, an adhesive such as a moisture-curing one-component polyurethane adhesive is applied to the back side of the floor board made of calcium silicate board or cement board. It is widely used that the reinforcing steel plates are integrally attached via the intermediary of both, but when both plates are attached, a roll coater or the like is attached to one of the two adhering surfaces of the two plates to be adhered to each other. It is manufactured by applying an adhesive agent by, and then press-bonding both plates by a press or the like, and sticking them together.

ととなる。However, as described above, this kind of floor board is particularly commonly used when the floor board and the reinforcing steel sheet are manufactured by simply pressing the floor board and the reinforcing steel sheet with an adhesive. Since the curing speed of polyurethane adhesives and the like is slow, a pressure bonding time of 10 to 20 hours is usually required to completely bond the floor substrate and the reinforcing substrate, and it takes time to bond both plates. Therefore, it has a problem of poor productivity. Also, if the pressure bonding time is shortened to improve the productivity, the curing of the adhesive is insufficient and sufficient adhesive strength between the two plates cannot be obtained, which in turn causes a part of the reinforcing steel plate to float from the floor-substrate. This causes a problem that the reinforcing effect of the reinforcing steel plate is not exhibited.

性が悪くなるという問題を有している。On the other hand, in order to increase the curing speed of the adhesive, it is sufficient to add a curing catalyst to the adhesive, but in this case, the viscosity of the adhesive increases during storage and the adhesive easily cures. In addition to the problem of the storage stability of the adhesive, the adhesive attached to the roll coater also easily hardens, resulting in poor workability.
