Curing sheets are used for curing equipment and construction objects. Usually, as the material of these curing sheets, flame-retardant sheet materials are often used from the viewpoint of safety. The flame-retardant sheet material is a sheet formed by adding a flame-retardant agent such as a halogen type to a heat-fusible plastic such as polyethylene, polystyrene, or polypropylene, and a plasticizer for the purpose of flexibility. In some cases, reinforcing fibers are embedded inside.

を手作業で貼り付ける方法が一般に採用されている。The curing sheet is used for the purpose of covering the object to be cured from the outside to prevent physical damage and to maintain an appropriate hardening rate of concrete. It is necessary to appropriately cut the sheet material in accordance with the above, and to join necessary parts to each other to form a predetermined shape. In order to easily bond the curing sheet at a construction site or the like, a method of manually attaching a joining tape such as a flame-retardant tape to the joining portion of the sheet materials is generally adopted.

After curing, the sheet material and the joining tape had to be separated and discarded separately. In addition, there is a problem that unevenness is likely to occur in the bonded portion of the joint portion, moisture and dust enter the inside through the bonding gap to cause dew condensation on the surface of the device, or cause functional failure of the device.

する。Further, even when the films are bonded evenly, there is a problem that the adhesive strength of the bonding tape is deteriorated due to the deterioration of the bonding tape, and the curing effect due to the peeling of the bonded portion is deteriorated. Then, these problems can similarly occur in sheet materials used for purposes other than curing. Therefore, an object of the present invention is to solve such a problem in the conventional joining of sheet materials, and an object thereof is to provide a new sheet material joining apparatus therefor.
