Abstract

PURPOSE:To prevent unsolidified concrete from leaking out of a space between the abutting sides of adjacent forms in the case where the plural forms are arranged in parallel to each other in forming a concrete wall having an irregular surface. CONSTITUTION:The side end edge 21b of a water nonabsorbent soft sheet 21 having a projection 21a or a protrusive stripe on its surface is turned around the side of a form 22 to form a form sealing part. The projection 21a or the protrusive stripe is provided on a section except the side end edge 21b of the soft sheet 21. Thus the sealing part formed of the soft sheet 21 can prevent unsolidified concrete from leaking.

2. Description of the Related Art Conventionally, in order to form a wall surface of a tile, first, uncured concrete is placed in a mold and then the mold is removed to construct a concrete wall. Then, as shown in FIG. 9, the base mortar 2 is applied to the wall surface of the concrete wall 1, and the tile 4 having the attached mortar 3 on the back surface is pressed against the base mortar 2. Further, as shown in FIG. 10, the base mortar is omitted, and the tile 4 is directly attached to the concrete wall 1 only by the attachment mortar 3.

As a method for placing wall concrete, which solves such a problem and is suitable for constructing a wall surface to be tiled, that is, it is possible to form a wall surface which is extremely excellent in the bondability with the base mortar and the adhesive mortar. In the method for placing wall concrete in which uncured concrete is placed in the formwork, the applicant attaches a plurality of non-water-absorptive soft sheets having a large number of protrusions or ridges on the inner surface of the formwork. In addition, a method for placing wall concrete was proposed in which a dovetail hole or a dovetail groove-shaped recess was formed on the concrete surface after hardening (Japanese Patent Application No. 2-78379.
That. ).

According to the method of the above-mentioned prior application, as shown in FIG. 5, on the inner surface of the mold 10 for placing uncured concrete,
A soft sheet 11 having a large number of projections or ridges 11a is attached, and thereafter, as shown in FIG. 6, uncured concrete 12 is placed, so that the surface of the concrete wall 13 after demolding is shown in FIG. As described above, the unevenness (concave portion 13a) derived from the protrusion or the ridge of the soft sheet is formed.
Since this soft sheet is non-water-absorbent, it has good releasability (releasing property) from concrete.

For this reason, when a plurality of molds are arranged in parallel with their side surfaces abutting against each other, a gap is created between the abutting side faces, and the uncured concrete may leak into this gap. In the method of the above-mentioned prior application, a sheet is attached in order to provide unevenness on the concrete wall. As a method for attaching the sheet, there are partial fastening with staples or an adhesive. With either of these methods of stapling and adhesive, the concrete will be partially torn or peeled off due to the force at the time of pouring the concrete, the concrete will flow between the sheet and the formwork, and the sheet will not be easily sunk into the concrete structure (embedded). There was a risk that
