ある。``Means for Solving the Problems'' Therefore, the present invention was proposed to solve the above-mentioned disadvantages, and its configuration is such that one corner of the tread having a triangular cross section is set at an angle close to 90 degrees. ,
On the symmetrical slope, concrete treads with one end of anchors buried at regular intervals and the other end protruding were fabricated in advance, and placed in a flat formwork with a concave cross section that would form the slope of the staircase. filled with concrete,
During the hardening of the concrete, a large number of treads are arranged in parallel by placing the sloping part of the tread and burying the protruding part of the anchor in the concrete, and then removing the mold after the concrete has hardened. . Therefore, the treads are manufactured using a formwork with a constant triangular cross section, so it is possible to make beautiful treads in advance.Concrete is poured into the flat formwork, and before it hardens, the treads are lined up and anchored. Since the protruding portion of the mold is buried and removed from the mold after hardening, it can be manufactured easily and can be made strong. Moreover, there is no fear that the formwork will burst because no great pressure is applied to the lower part of the formwork.

The formwork that forms the tread is triangular in cross section, with the bottom corner at an angle close to 90 degrees, the inside of which is filled with concrete 2, one end of the anchor 3 is inserted into the concrete 2, and the other The tread plate 4 is manufactured in advance by making the end protrude, hardening, and demolding. Next, concrete 7 is filled into the flat formwork 6 with a concave cross section that forms the sloped part 5 of the stairs, and before this concrete 7 hardens, the previously manufactured treads 4 are arranged in a stair-like manner to form the anchors 3. The protruding portion is buried in concrete 7, hardened, and removed from the mold after hardening. Reference numeral 8 denotes an auxiliary rod used together with the formwork 1, which cuts and smooths the lower end of the front surface of the tread plate 4 so that it can be stably placed on the rear of the lower tread plate 4, and has a triangular cross section. . To use this, as shown in FIG. 7, the upper part of the concrete 2 placed in the formwork 1 is pressed against the edge of the formwork 1. 9 is a reinforcing bar.
