  The structure of the conventional spiral staircase is a structure that supports the weight of the main body with a central support column, and therefore reinforcement work for the installation location was indispensable.

  Furthermore, the conventional spiral staircase has many problems that cannot be avoided, such as welding work on site and handling heavy objects.

  It was almost impossible to change the specifications of the conventional spiral staircase on site because of the large amount of equipment and a lot of work.

  The conventional spiral staircase is simple and has good design due to the structure of the step board, handrail and support column, but it has a shape that has many gaps and falls on the step board, and the placed object may fall down.

The fan-like spiral structure of the present invention is a fan-like spiral structure formed by stacking a plurality of fan-like flat plate bodies having the same shape, and the fan-like flat plate is used for fixing the main body at a constant radius from a central point. A plurality of holes are provided, and a component unit in a state in which a fixing bolt is fixed with a nut in the body fixing hole of the flat plate of the same shape is formed, and the component unit is overlapped and fixed while being shifted by a predetermined angle, A fan-shaped spiral is formed with the thickness of the flat plate body, and further, a support hole is formed at the center point of the fan-shaped flat plate, a support column is set up in the support hole, and the component units are stacked and fixed while being shifted by a certain angle. A step is formed by forming a step by attaching a step plate to the step using a mounting bracket .

  It can be used as a staircase by attaching a step board and a handrail to the fan-like spiral structure of the present invention.

  According to the present invention, the carrying-in operation is dramatically improved over the conventional spiral staircase even in a narrow carry-in route where only a narrow house / elevator cannot be installed.

  In the present invention, in order to achieve efficient construction, the load is supported at one point, and the structure is a fan-like structure in which the main body 1 is stacked while being shifted at a fixed angle with the center as a support column 1. Since it is dispersed in the shape of the main body, it is possible to simplify the reinforcement work of the floor that supports the pillars necessary for the conventional spiral staircase.

  Since the fan-shaped spiral structure of the present invention is of a laminated type, there is no gap in the spiral portion, so it is possible to ensure privacy from below, and furthermore, a small space is created below when a corrugated plate is attached. By installing a lighting fixture, the user's night vision can be secured and the interior can be used as an interior.

  As an example of the fan-shaped spiral structure according to the present invention, fixing bolts are fixed to a plate of the same component with a nut with respect to a plurality of holes that are located on a radius with respect to an arbitrarily determined center point. By fixing the components while shifting them at a fixed angle, they are molded into a fan-like spiral with the thickness of the main body, and the load on the floor is distributed by dispersing the excess weight on the floor with the installation area of the plate-shaped molded parts of the main body. It has been reduced.

  Moreover, it is a fan-shaped spiral structure of the shape which can be used as a stair by attaching a step board and a handrail to a spiral structure.

  In the spiral structure as an embodiment of the present invention, the bolt 2 is applied to the part of the flat plate main body 1 in the second hole from the front of the spiral traveling direction. It becomes possible by long fixing bolts and nuts, and it is possible to change the right and left rotations of the spiral by changing the back and front of the flat plate body and fan-like without changing the number and shape of parts It is the flat plate main body which aimed at multifunctionalization of the member of a spiral structure.

  It also relates to fan-shaped spiral structures composed of single tubes and bolts, and because of the small number of parts, it is easy to manage construction failures and missing parts. Shipment management in unit sales such as a spiral staircase becomes easy, and it is possible to improve the efficiency of work on site. Other than the flat plate body 1, since it is a commercial product, there is little loss and the cost can be reduced.

  The process of fixing two places with the assembly fixing nut 4 while stacking the main body 1 is connected to each other in a spiral manner, so that when the number increases, the weight is balanced and the strength increases and the fixing main part is fixed. Fan-shaped spiral structure with excellent strength and workability because it is moved to the outer periphery.

  According to the present invention, the fan-shaped spiral structure distributes the weight to the center specific to the spiral to the outer periphery and moves the weight to the entire outer surface and the part installation surface, so that the load from the top is reduced and treated as a guide. Because it does not require strength, considering the length and weight that can be loaded even with long pillars, it can be connected to the desired length using a joint etc. at the site, and a fan-like spiral structure that can be almost constructed if it is a loading route that allows humans to pass .

  Furthermore, it is preferable that the flat plate body of the fan-shaped spiral structure is attached using an adhesive and a screw in addition to the fixing nut.

  Next, the actual situation of the present invention will be described with reference to the drawings. FIG. 1 is an overview of a state as a staircase with a step plate attached to a fan-like spiral structure according to an embodiment of the present invention, and is an example of clockwise stacking construction. See Figure 1

  The fan-shaped spiral structure unit of the present invention is formed by overlapping a plurality of flat plate main bodies 1 by joining them with bolts 2 and main body fixing nuts 3 and fixing them to the support column 1 in a spiral shape.

The bolt 2 used by the fan-shaped spiral structure is
FIG. 11 in which the length of ((number of outer peripheral holes−2) × thickness of flat plate body 1) + (thickness of nut 3 × 2) is preferable.

  With respect to a plurality of regularly spaced holes located on a certain radius with respect to the center of the support hole 11H of the flat plate body 1 of the fan-shaped spiral structure, the maximum is the direction of overlapping the second hole from the spiral direction. The bolt 2 is fixed with the main body fixing nut 3 in the extended state. See Figs. 4, 5, 6 and 7 (common to all construction methods)

  By fixing the bolts 2 in the second and fourth holes from the end of the spiraling direction in the above parts with the fixing nut 4, the second hole from the end is set to 2 from the number of outer peripheral holes. By fixing the number of the subtracted number and fixing the number of the fourth hole from the last by subtracting 4 from the number of the outer peripheral holes, it is possible to keep the tightening condition at the connecting portion well. See FIG.

  Furthermore, it is preferable that the flat plate body of the fan-shaped spiral structure is attached using an adhesive and a screw in addition to the fixing nut.

  According to the fan-shaped spiral structure of this embodiment, the construction method of stacking from below and the construction method of connecting in a suspended state from above can be selected without changing the number of parts and the shape of the flat plate body.

  Furthermore, according to the fan-shaped spiral structure of the embodiment, the clockwise and counterclockwise construction methods can be selected without changing the number of parts and the shape of the flat plate body.

In the case of FIG. 4, first, align the parts of the flat plate body 1 with the center as a reference, place the outer peripheral hole for fixing the body in front of the fourth hole from the back of the spiral traveling direction, and attach all the bolts 2. Next, all the holes on the outer periphery of the flat plate body are drilled into large holes, aligned with the holes and pillars in the spiral direction, and fixed to the floor with screws and adhesive, and the bolt 2 and nut 3 are attached to the flat plate body 1 described above. The parts are stacked with the holes shifted from the direction of the spiral, the assembly fixing nuts 4 are attached to the second and fourth from the end of the spiral, and the second extra bolt is cut and stacked. The cutting work after the completion of the cutting of the plurality of bolts initially attached is eliminated, and the working efficiency can be improved. Refer to FIG. 3 and FIG.

FIG. 3 will be described as an example.
When fixing from 1H to 10H, 1H and 3H are large holes that hide the nut 4 of the lower part, 2H and 4H are small holes for fixing the main body, and 5H, 6H, and 7H are all Through holes for screw bolts, 8H is a large hole that hides the fixing nut 3 of the lower main body, 9H is a small hole for mounting the whole screw bolt 2 to the main body fixing nut 3, and 10H is a large hole that hides the main body fixing nut 3 when the next main body is mounted In the case of construction, the use of holes is common to both clockwise and counterclockwise directions. See Figure 3

  Therefore, there is no limit on the number of holes. The more holes, the more the number of pieces that can be sandwiched in one piece, and the strength will increase, but the accuracy will not be achieved. A moderate number of holes is preferred because no longer occurs.

  The fan-like spiral structure can be changed by changing the long direction of the bolt 2 to which the flat plate body is attached in the reverse direction in order to change the clockwise FIG. 4 to the counterclockwise FIG. See FIG. 3, FIG. 4, and FIG.

  Further, stacking the fan-shaped spiral structure (clockwise) Fig. 4 is hung by replacing the bolt in the second hole from the front in the direction of travel and replacing the bolt second in the direction of travel. Lowering construction (clockwise up) The parts shown in FIG. 6 can be easily changed.
