Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated staircase that is mainly constructed inside a building and can be assembled.

[0002]

2. Description of the Related Art As a conventional technique, since it is welded, fixed and integrated in a factory, it has to be transported by a large vehicle to a construction site, which is difficult. Further, particularly when a spiral staircase is installed inside a building, the spiral staircase is an obstacle because it is installed at the first stage and then the surrounding area is constructed. Furthermore, after installation, it is likely to be damaged or soiled, requires a great deal of labor and cost for curing, and has various problems in practical use.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and since the purpose thereof is an assembling type, it can be easily and quickly installed in a building, especially after the building is installed, and is not necessarily large in size for transportation. It provides a prefabricated staircase that does not require a car and does not worry about damage or dirt, and is particularly effective for installation in narrow spaces, and because the treads are directly attached to the handrails, it can be installed in a compact size, and is a transparent polycarbonate honeycomb. By using as a tread, it is possible to provide a light-weight prefabricated staircase that does not block light.

[0004]

[Means for Solving the Problems] As a means for achieving the above-mentioned object, a stair consisting of a pillar main body in which a handrail is provided between two pillars, and an inner end portion of a tread plate is attached to the handrail. It must be equipped with a mounting part for mounting tools. The pillar of the pillar body, which consists of two or more pillars, is provided with a mounting part for mounting the fitting at the inner end of the tread, and the pillar can be used as a handrail. In addition, the outer end of the tread should be provided with a fixing part that is attached to a wall surface or the like. The mounting part must have an insertion hole. Furthermore, the fixed part should have a locking piece. The structure of pillars and handrails must be a front ladder type. Furthermore, the arrangement of the columns must be substantially circular in plan. The arrangement of the columns is a polygonal shape in a plane. Besides, the tread is
It is characterized by having a transparent polycarbonate honeycomb.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the prefabricated staircase of the present invention will be described below in detail with reference to the drawings. This prefabricated staircase 1
Is composed of a column main body 2 and a tread 4. The pillar main body 2 is formed by providing handrails 3−− made of square pipes at required intervals between two pillars 2a made of square pipes facing each other. Sideboards of each handrail 3 have a step-like shape which will be described later. The mounting portion 3a is formed by inserting the mounting tool provided at the inner end portion of the mounting hole into the mounting portion 3a, and the mounting portion 3a is configured as a front ladder type. The tread plate 4 is provided with a fitting 4a1 by an insertion plate at an inner end portion of a flat plate-shaped tread body 4a, and a fixing portion 4a2 by an L-shaped locking piece attached to a metal fitting provided on a wall surface or the like at an outer end portion. It is provided. In addition,
The tread 41 in the landing is larger than the tread 4,
Similar fixing portions 41a2 are provided at five locations around the periphery.

An example of use of the above-mentioned assembled staircase will be described.
For example, when constructing a staircase in a building (not shown), the pillar body 2 is fixed to the anchor A that is provided in advance by a nut N. After that, the attachment 4 of the tread 4 is attached to the attachment portion 3a of the handrail 3.
a1 and then the fixing portion 4a2 of the tread 4 to the wall K
Complete the installation by inserting it into the metal fitting K1 attached to. When using the stairs thus completed, it is sufficient to hold the handrail 3 provided between the columns 2a and go up and down the stairs.
You can put small items on the top of the and use it as a shelf.

Next, another embodiment will be described. The assembling-type staircase 21 has columns 22a of a column body 22 formed by arranging columns 22a made of square pipes at required intervals in a substantially circular plane shape.
On the side surface of the, a mounting portion 23a is provided by a vertical insertion hole into which a vertical insertion plate of an attachment provided at an inner end of a step plate, which will be described later, is inserted. Further, the tread 24 has a plane fan shape and a reinforcing plate 24a1 provided on the bottom surface, and a vertical insertion plate 24b1 and receiving plates 24b2 and 24b2 fixed by bolts at the inner end of the tread body 24a formed in a side T shape. Naru attachment 2
4b is provided.

This prefabricated staircase 21 is suitable for a spiral staircase, and the pillars 22a are used instead of handrails when going up and down, so that it is easy to move up and down, and it is generally used at the upper part of the outer end of the tread body as necessary. A handrail may be provided.

Next, another form of tread will be described. The tread plate 34 has a core made of polycarbonate honeycomb 34a and upper and lower faces of which polycarbonate flat plates 34b and 34b are fixed to each other with an adhesive or the like, both of which are transparent.

The tread plate 34 is lightweight, has high strength, and is transparent, so that the upper light source can be effectively used to the lower part.

In the above embodiment, the support column is not limited to the square pipe but may be a round pipe. Further, the mounting portion provided on the handrail or the column, the mounting member for the tread, and the fixing portion may have other forms as long as they have similar functions and effects. further,
The arrangement of the columns is not limited to the substantially circular shape in the plane, and may be a quadrangular shape in the plane.

[0012]

EFFECTS OF THE INVENTION 1. By providing a handrail between columns, stairs can be constructed even in a narrow place, and small articles can be placed on the upper surface of the handrail to be used as a shelf. 2. The installation is easy and the assembly can be done in a short time by the combination of the foot plate mounting tool, the fixing part and the column mounting part. 3. There are few parts, resulting in a significant cost reduction. 4. Each part is subdivided so that it can be carried into a narrow space. 5. It can be installed permanently or temporarily and can be easily disassembled. 6. Strength can be obtained with a small number of parts by making the pillar body a ladder type. 7. By arranging the pillars in a substantially circular shape or a polygonal shape in a plane, various needs can be met. 8. The footboard can be attached directly to the support, the support can be used as a handrail, and efficient construction can be performed. 9. The tread plate is made of transparent polycarbonate honeycomb so that it is light and durable and can effectively use light.
