Abstract

PROBLEM TO BE SOLVED: To improve binding efficiency by moving a forming end surface of a trowel on placed mortar in a contact condition to form linear waveforms of non-angular curvature at ridge parts and trough parts, pressing a unit slate on it, and binding it while adjusting a level to other slates. SOLUTION: A forming end surface 3 of a trowel 1 is moved in contact with an upper surface of mortar applied on a base surface, and plural linear waveforms having a similar form to sine curves are formed at ridge parts and trough parts. Next, a slate is pressed and placed on a formed surface of the linear waveforms, and it is bound while adjusting a level of it to other slates already provided. The slates are thus positioned to a uniform level, and in pressing and placing them, it is smoothly moved to flow to the ridge part while preventing breakage of mortar to eliminate bubbles, etc., for providing a uniform binding surface. A ratio of height of the ridge parts and height of the trough parts to a reference surface as a mark for final installation of the slates is set at 6:4 in forming the waveforms. Push-in quantity of the slates is thus increased, and a level adjustment range is enlarged, thereby level adjustment of the slates can be easily performed.

For this reason, it is necessary to press the unit stone plate 10 to a certain height in order to adjust the level. However, in the case of the conventional molding surface F2 formed in a square shape, the peaks 12a and the valleys 1 are formed.
Since the volume ratio with 2b is the same, it can be pushed only up to about half the height of the mortar molding surface.

[0007] Further, in such a square molding surface F2,
As shown in FIG. 4B, when the unit stone plate 10 is pressed and placed on the mortar forming surface F2, the rectangular mountain portion 11 collapses, and the mortar collapsed from the side surface moves as indicated by an arrow. However, since the mortar that has collapsed from the top does not fall evenly into the valley, when the unit stone plate 10 is pressed and placed on the mortar molding surface F2, bubbles are mixed in the mortar in the bonding portion, and the bonding strength is reduced. Occurs.

In order to further secure the level of the unit stone plate 10, when the unit stone plate 10 is further pushed in, the unit stone plate 1
Since the mortar is moved in the direction of the arrow (left side) internally by the pressing force of 0, another unit stone slab 10 (left side in the figure) already laid is pushed up and the level of the laid slab is disturbed. Have the problem that
