BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to civil engineering and marine concrete structures such as tunnels, piers, bridge girders, and slopes, and concrete structures such as buildings and condominiums. The present invention relates to a mortar construction method and a mortar layer structure used for attaching a mortar reinforcing material such as a lath to a mortar applied to a structure to which a reinforced sheet is adhered, such as an outer wall of a wooden house, when the mortar is applied.

2. Description of the Related Art Conventionally, as an example of this type of structure, a civil engineering concrete structure is exemplified. As means for reinforcing an existing or newly installed pier, a carbon fiber sheet, an aramid fiber sheet, or the like is provided on the surface of the structure (the concrete surface of the pier). It is common practice to attach a reinforced sheet. Furthermore, since there is a risk that the reinforced sheet may spread due to a fire, the Fire Services Act stipulates that a mortar layer be applied over the reinforced sheet.

[0003] As a method of applying such mortar,
As shown in FIG. 13, the reinforcing sheet 34 impregnated with an adhesive 32 such as an epoxy resin is
Penetrate an anchor 35 into the structure 31, and anchor and support a mortar reinforcing material 36 such as a lath on the anchor 35,
A method of laying the mortar from above by wet or dry spraying or plastering iron plastering or the like and laying the mortar layer 38 is also conceivable.However, according to such a construction method, the insertion hole for inserting the anchor has a reinforcing sheet. In this case, the fibers constituting the reinforced sheet are cut off, resulting in a problem that the strength is reduced, which is not preferable.

[0004] Therefore, an adhesive primer having excellent adhesiveness to mortar is applied to a reinforced sheet adhered with an epoxy resin or the like, and the primer is evenly finished with a trowel or the like. A mortar reinforcing material consisting of a mesh sheet, which is a fiber-reinforced plastic molded product, is adhered, and mortar is laid from above by means of spraying or the like,
There is also a method of constructing a mortar layer.

However, in the above-mentioned mortar application method (method of applying a primer on a reinforcing sheet and attaching a mortar reinforcing material), an adhesive primer excellent in adhesiveness to the mortar is applied. Even when the adhesive such as an epoxy resin to which the reinforcing sheet is adhered is cured to completely form the plastic layer, the chemical adhesive force between the adhesive and the primer is significantly reduced. Therefore, it is difficult for the mortar to firmly adhere to the surface of the reinforcing sheet, and there is a possibility that the mortar layer may peel off or float.

Further, in the above-mentioned construction method, it is necessary to apply and finish an adhesive primer on the reinforced sheet, which not only complicates the work, but also cures the cold-setting resin impregnated in the reinforced sheet. Until this process is performed, the adhesive primer cannot be applied, resulting in a disadvantage that the application time is long.

The present invention has been made in view of the above-mentioned problems, and when a mortar layer is applied to a structure to which a reinforced sheet is adhered, the mortar layer can be easily formed without deteriorating the effect of the reinforced sheet. It is another object of the present invention to provide a mortar construction method capable of performing a thick construction. It is still another object of the present invention to provide a mortar layer structure in which mortar applied on a reinforcing sheet is difficult to peel off.
