Conventionally, to create a pattern such as a brick shape on the exterior wall of a building, a joint material is pasted on the exterior wall base material such as concrete, mortar, PC board, slate board, ALC board, etc., and then cement-based, acrylic, etc. The so-called joint design spraying method is used, in which a spraying material such as silica is sprayed and the joint material is peeled off before the spraying material sets.
As described in Publication No. 48-43453, a release layer with adhesive properties is provided on one side of a base sheet, a pressure-sensitive adhesive layer is provided on the back side of the base sheet, a sheet with a pattern cut out is laminated, and a release layer is further placed on top of that. A transfer sheet made of laminated paper is used.

ない等の欠点があつた。 However, since the above sheet has a cut-out pattern, the pattern of the image (the shape of the joints) tends to deform when the release paper is peeled off and the sheet is pasted onto the exterior wall base material, so it is difficult to maintain the shape and paste it onto the exterior wall base material. It was difficult. In addition, since the sheet with the pattern cut out is made of a thin plastic sheet, it has poor adhesion to the exterior wall base material and may peel off during work. There were drawbacks such as chipping and the shape of the joint material not being sharp.

なされている。 Further, the adhesive force between the adhesive layer 31 and the foam sheet 1 is greater than the adhesive force between the adhesive layer 2 and the release sheet 5, and is smaller than the adhesive force between the adhesive layer 2 and the exterior wall base material to be pasted. The release sheet 5 can be peeled off without removing the joints 11 or the scraps 12 of the foam sheet 1, and the release sheet 5 is peeled off and the adhesive layer 2 is applied to the exterior wall base material to be pasted. When the see-through film 3 is peeled off after the sides have been attached, it can be peeled off together with the lees extraction part 12, leaving the joint part 11 behind.

Those having a foaming ratio of 5 to 20 times are preferable because they have excellent properties such as stiffness, elongation, flexibility, and ability to fit curved surfaces and uneven surfaces. Further, the foam sheet 1 may be reinforced on one or both sides with a synthetic resin film, paper, nonwoven fabric, or the like. The thickness of the foam sheet 1 may be appropriately determined depending on the thickness of the spray material to be sprayed, but it is generally 0.5 to 3 mm, and 0.8 to 1.5 mm is preferably used.

Since the structure of the adhesive sheet for architectural joints of the present invention is as described above, when the release sheet is removed, the joints and scraps are not removed together with the release sheet, and the shape of the joints is deformed. Therefore, even if the shape is complex or large, it can be applied uniformly to the exterior wall base material without deforming the joint shape, and since the joint part is made of foam sheet, it can be applied evenly to the exterior wall base material. It can be applied reliably even if the material has unevenness, it will not fall off during spraying, the scum will be reliably removed when removing the see-through film, and the thickness of the spraying material will be lower than the thickness of the material being sprayed. By making the foam sheet a little thicker, the sides and edges of the sprayed material will not be chipped when removing the joint area after spraying.
従つて本考案の建築目地用粘着シートを使用す
