Description

    The present invention relates to an assembly-type staircase suitable for manufacturing a staircase whose direction of travel changes depending on the height of a spiral staircase or the like.

    A conventional spiral staircase has a complicated structure. In particular, when a wall surface is provided on a staircase or a handrail is attached to prevent a fall or the like, the structure becomes more complicated and expensive.

    Therefore, most of them are spiral staircases that have the same direction when climbing the stairs and rise at a certain rotation angle, and there are almost no stairs that change the ascending direction or change the rotation angle when climbing. Even if it exists, the production is cumbersome and extremely expensive.

    The present invention provides an assembling-type staircase that can easily manufacture various staircases such as a staircase whose rising direction changes midway.

    The assembly type staircase of the present invention is configured such that each staircase member constituting the staircase is sequentially stacked, and each staircase member is rectangular, or one of the lateral sides of the rectangle or It is composed of a stepped plate having both sides inclined and L-shaped left and right stepboard support members that support the left and right end surfaces of the stepboard, and the left and right stepboard support members are in the vertical direction of equal length. The extending longitudinal support part is formed in an L-shape consisting of a lateral support part extending in a horizontal direction of an appropriate length according to the lengths of the left and right end faces of the step plate. A plurality of members are sequentially stacked, and on the upper end surface of the vertical support portion of the L-shaped step plate support member of one stair member, the tip portion of the lateral support portion of the end surface support member of the other stair member The upper and lower staircase members are stacked and fixed by this means. And it forms a step by returning Ri.

    In the assembly-type staircase of the present invention formed in this way, when all the staircase members have a rectangular shape with the same step plate surface shape, the staircase rises and falls on a straight line.

    In addition, if each staircase member has a stepped plate surface shape that is inclined in the horizontal direction and has the same shape (a shape having the same inclination angle), it is counterclockwise or clockwise depending on the inclination direction. Become a spiral staircase that rises. Here, depending on the angle of the tilt direction, a spiral staircase with a gentle turning direction (rotation angle when ascending / descending) or a spiral staircase with a strong turning direction is obtained.

    Further, by sequentially changing the inclination angle of the step plate, a staircase whose turning angle changes is obtained.

    Further, by combining the change in the inclination angle and the change in the inclination direction, for example, a spiral staircase that changes from clockwise to counterclockwise is obtained.

    Further, by combining the shape of the step plate with a rectangle and an inclined shape, a stair that rises linearly and rises spirally from the middle can be formed.

    According to the assembly-type staircase of the present invention, by selecting the shape of the step board of each stair member constituting the staircase or by making the shape of the step board different, the stair ascending and descending linearly, the turning direction, etc. Various staircases such as different spiral staircases can be easily manufactured.

    Moreover, the assembly-type staircase of this invention can be easily attached by joining and fixing a handrail etc. to the horizontal support part of the L-shaped support member of each staircase member. Moreover, the handrail can be attached even in the case of a spiral staircase, and can be easily attached.
