Definitions
- the present invention relates to a precast concrete-concrete staircase block used for casting stairs in place and a stairway construction method using the same.
- the above-mentioned conventional method is not suitable for construction when the temperature difference is extremely large or especially in the area where freezing occurs.
- An improved method over the above conventional method is the method using an L-shaped stair block (L-shaped stair method, see Fig. 5). This is a precast with a cross-sectional shape of 90 ° counterclockwise for the ascending stairs (90 ° clockwise for the reverse L-shape). There o
- stairs are a means of traffic on slopes, and shortening the period is an absolute condition. Especially in the case of renovation of stairs in existing residential areas, it is necessary to minimize the period during which all roads are closed. In this case, it is desirable that new stairs can be constructed continuously from one end while using the old stairs partially.
- the conventional method described above has sufficiently responded to such a request due to various construction reasons.
- the staircase block according to the above-mentioned known technology is transported by human power. ⁇ It is too heavy for installation, and the gap between adjacent blocks is easy to shift, and a gap such as air bubbles between the base concrete surface and the backside of this staircase block. Problems have been experienced, such as the tendency to peel off and to easily cause peeling due to the expansion of residual air and infiltration moisture. Disclosure of the invention
- the problem to be solved by the present invention is to overcome the problems of the above-mentioned prior art staircase block, and to carry it manually. ⁇ Reduce the weight so that it can be installed. That there is no gap between adjacent blocks after construction, and that the floating of the blocks due to heat and cold does not cause peeling. Means for solving the problem
- the above-mentioned problem is to reduce the weight by forming large depressions on the riser surface and the back surface of the block, and to form a groove on the side surface of the block to prevent misalignment that connects adjacent blocks with mortar.
- the problem can be solved by a staircase block in which a radius (partially cylindrical concave surface) having a predetermined radius is formed at the inner corner of the depression on the back surface so that a corner that prevents filling of the bonding mortar is prevented.
- the staircase block according to the present invention has a height of 330 kg in length and a weight of 26 kg, which can be carried by human power, due to the weight reduction effect of the depression formed on the rise surface and the back surface. enter. This is a great advantage for construction on slopes where heavy equipment is difficult to enter.
- the mortar to be laid under the block is filled to every corner of the recessed space and does not form a cavity, so it is hot and hot.
- ⁇ Expansion in cold weather Residual air and moisture in the cavities that cause destruction can be eliminated in advance.
- a third step is to place a spirit level along the front edge of the stepping surface of the temporarily placed stair block and strike it with a sand hammer while checking the horizontal level to adjust the corner of the riser surface to the specified height.
- the fourth step is to use a slant (gradient measuring instrument) to pull out and adjust the camber so that the stepping surface has a constant gradient.
- a slant gradient measuring instrument
- the sixth step in which the camber is removed and mortar is pierced into that part, the seventh step in which the media between the adjacent stair blocks is firmly pierced using plywood or the like to complete the installation, and
- Example 1 This is a stair construction method using a stair block that includes a work completion process of cleaning sand and trash before finishing the image.
