FINISH WORK EXECUTING METHOD FOR RISER DEVICE, BEARING DEVICE, BEARING STAND DEVICE, AND CONCRETE STAIRWAY, TO BE USED FOR FINISH WORK EXECUTION FOR CONCRETE STAIRS

摘要

PURPOSE:To enable the work of concrete stairway with high precision, to be executed by executing the finish work of the concrete stairway easily and quickly, even without skillful workers, and by regulating the positions of risers to be the riser sections of the concrete stairway, easily fixed. CONSTITUTION:On the front side of the stepped sections of roughly constructed concrete stairway 4, via a bearing device 2, a riser 10 is set at a required distance, and a void section is formed between the front face 41 of the stepped section and the riser 10, so that the upper side section 13 of the riser 10 may be made higher than the upper face 42 of the stepped section by a required level. Then, on the upper face 42 of the stepped section, mortar is placed, and the void section is filled up with the mortar, and on the upper face 42, a tread is formed, and the surface 100 of the riser 10 is set as a riser face, and the stairway is constructed.
