Abstract

PROBLEM TO BE SOLVED: To reduce the material loss of a block, simplify its execution and obtain its excellent outer appearance of the exterior block by a method wherein the filling of a hydraulic substance in layers in a form and the spraying of a water-based substance upon each layer are repeated alternately. SOLUTION: In a prepared form 1 made of an organic foamed material so as to form a relief pattern onto the inner surface of the form, a hydraulic substance 3, the amount of which is metered so as to make a predetermined thickness, is filled in layers so as to make a filled surface horizontal. Next, a water-based substance 4 is sprayed in the layer of the hydraulic substance 3 by an amount, which is sufficient for hardening the hydraulic substance 3 through infiltration. Next, the filling process of the hydraulic substance 3 and the spraying process are carried out again so as to successively repeat both the processes until a predetermined height is obtained. After the execution of the final spraying process and a predetermined curing, an exterior block 5 is obtained. Thus, the exterior block 5 can be formed at low cost under the condition that its execution is very simple and its material loss is small. The external appearance of the obtained block 5 has a natural drape and handle.

As a filling method, the hydraulic substance 3 is measured so as to have a predetermined thickness, and is filled so that the surface is horizontal. By making the surface horizontal, the sprayed water-based substance uniformly penetrates to the surface. The thickness of the layer varies depending on the hydraulic substance 3, but is preferably 50 to 200 mm in the case of cement. If the thickness is less than 50 mm, the man-hour is required if the height of the external building block is high, and if it exceeds 200 mm, the cement hardening reaction becomes insufficient.
