Description of the Related Art As an assembly type of curved staircase of this type, conventionally, a girder material is projected to a cylindrical boss and a step plate is supported by this girder material, and the cylindrical boss is connected by a bolt. However, there is one in which a curved staircase is formed by stacking upward and changing the angle of the projecting direction of the girder material to sequentially change the angle of the step plate (see US Pat. No. 3,667,176). According to such a configuration, there is an advantage that a curved staircase having an arbitrary number of steps can be obtained by appropriately changing the number of stacked steps of the cylindrical boss.

It is only necessary to stack (11) and change the angle of each girder (12) (13), and if the number of each boss (11) (11) is further increased, a spiral staircase can be constructed. . Further, as shown in FIG. 7, when the circumference of the bent portion (5) is at a right angle, from the center of the bent portion, that is, the center of the boss (11) to the tip of the second girder (13). The length will be different for each plate support unit (27), but in this case,
The second girders (13) having different lengths may be connected to the respective first girders (12). In this case, the boss (1
The same material can be used for 1) and the first girder material (12).
Further, since the outer peripheral side of the step plates (4a) (4b) is wider than the center thereof, the horizontal portion (18) of the sasara (17) attached to the second girder (13) side is correspondingly widened. ) Is
It is longer than the horizontal part (18) of the first sasara (16). Also in this case, if the widths of the step plates (4a) (4b) ... Are different, it is sufficient to replace and install another sasara having a different length of the horizontal portion (18), or the step plates ( 4a)
(4b) If the heights are different, the vertical parts (19) with different lengths may be exchanged and used.

る。EFFECTS OF THE INVENTION According to the present invention, it is not necessary to connect the bosses one by one while stacking the bosses one by one, and the bosses can be stacked at once and then tightened and fixed at the same time by the through bolts. Moreover, before tightening the through bolt, or by loosening the through bolt,
Since each boss can be rotated in the horizontal direction to adjust the angle of the girder member, it is not necessary to assemble the girder member while always measuring the angle accurately in advance.

効果がある。In particular, in the present invention, since a plurality of sasara are attached across the upper girder material and the lower girder material or the sasara, the step plate can be firmly supported and the girder material and the sasara can be securely supported by the step plate. Since the upper surface is covered and the front surface of the girder material is covered with the sliding plate, the frame composed of the girder material and the salsa is not visible from the up-and-down side, and the appearance is good. Therefore, if the girder material and the sasara are made of high-strength metal, and the steps and indentations are made of wooden boards, it is possible to provide a curved staircase with an excellent appearance that can also be used as a decorative staircase inside a house. You can Further, the indentation plate is fitted and attached so as to straddle the groove on the back surface of the upper step plate and the groove on the upper surface of the lower step plate. There is an effect that it is securely fitted and held inside.
