Abstract

The utility model discloses a rotary stairway. One end of a steel end plate is hinged and fixed with a small end of a bone junction through a fastening screw rod. A big end of the bone junction is hinged and fixed with the small end of a next bone junction through the fastening screw rod. A plurality of bone junctions are stacked into a pedal keel, a pedal is fixed on a horizontal panel of the bone junctions and an upright post with a stairway handrail is fixed and arranged on the pedal. The utility model can not be limited by layouts, and can be arbitrarily rotated according to needs and personal aesthetic points. Thus the utility model has the advantages of space saving, various modeling, flexibility and convenience, simple installation, short building period, low cost, normalized design of universal components and easy organization and manufacture.

Description

Rotary stairway

The utility model relates to stair, especially a kind of stair that can rotate arbitrarily with the need.

In the building of small-sized dwelling house, villa; the design scheme of stair, difficulty of construction, institute take up space and decoration level etc. is occupied critical role; the most difficulty of construction of present stair are bigger; waste takes up space; and the general layout difference in various rooms; design scheme is also different, is difficult to make Normalized Design and large-scale production, thereby makes its integrated cost higher.

The purpose of this utility model is that a kind of novel stair will be provided, it not only gives indoor achievements elegance, luxurious decorated style, main is that its saving takes up room, and be not subjected to the restriction of layout, can be according to layout needs and any rotation direction Site Design of individual aesthetic standard, various shapes, flexible, it is installed simply simultaneously, and the duration is short, and cost is lower, it is the assembly type stair, standardization universal component design is easy to tissue production, has fire prevention, mothproof, anticorrosion, moistureproof, wear-resisting robust characteristics in addition.

The purpose of this utility model is achieved in that a kind of Rotary stairway, comprise one group of pedal, column and balustrade, steel end plate one end is hinged and fix by nut by the small end of fastening screw and bone knot, the small end that the big end of bone knot is tied by fastening screw and next bone is hinged and fix by nut, several bone knots are stacked to the pedal keel with the bone knot, on the horizontal panel of bone knot, be fixed with pedal, be installed with the column of band balustrade on it again.

The described steel end plate other end is fixed on top layer beam or upper strata crossbeam and the ground by expansion bolt.

The big end of described bone knot fixes on the ground by set bolt.

The bone knot is the support with supporting capacity that is welded with steel pipe and steel plate.

The height of bone knot is the calibrated altitude of broadstep.

Be provided with the profile housing in bone knot outside.

The pedal that this bone is tied, sideboard, handrail and column all adopt inorganic composite materials to be made.

The utility model is because several bones knot is stacked to the pedal keel with the bone knot, and each bone knot is rotatable in the horizontal direction, so it is not subjected to the restriction of layout, can design definite rotation direction arbitrarily according to field layout needs and individual aesthetic standard, various shapes, flexible, and also saving takes up room; Because it is the assembly type stair, the universal component design that standardizes is easy to tissue production, and it is installed simply simultaneously, and the duration is short, and cost is lower; Because pedal, sideboard, handrail and column that this bone is tied, all adopt inorganic composite materials to be made, can not only give indoor achievements elegance, luxurious decorated style, main is, and it also has fire prevention, characteristics such as mothproof, anticorrosion, moistureproof, wear-resisting and sturdy and durable.

Below in conjunction with concrete structure and the operating principle of accompanying drawing detailed description according to the Rotary stairway that the utility model proposes.

Fig. 1 is the side-looking partial sectional view of the utility model stair;

Fig. 2 is the vertical view of the utility model stair;

Fig. 3 is one of rotation form;

Fig. 4 is two of a rotation form;

Fig. 5 is three of a rotation form;

Fig. 6 is four of a rotation form;

As shown in Figure 1, 2, a kind of Rotary stairway comprises one group of fastening screw 1, one group of bone knot 2, steel end plate 3, one group of pedal 4, column 5, balustrade 6 and set bolt 7.

Steel end plate 3 one ends are fixed on the top layer beam 9 by expansion bolt 8, and the other end is hinged and fix by nut with the small end of bone knot 2 by fastening screw 11, and during nut on unclamping screw rod, rotatable bone is tied required direction; During nut on tightening screw rod, can the bone knot is fixing, the big end of bone knot 2 is hinged and fix by nut with the small end of next bone knot 2 by fastening screw 1, by that analogy, the big end of N bone knot 2 that contacts with ground fixes on the ground by set bolt 7, can form rotation form such as Fig. 3,4,5,6 stair like this.

On the horizontal panel of bone knot 2, be fixed with wooden pedal 4 of inorganic generation, be installed with the column 5 of band sideboard 61 and balustrade 6 on it again by wood screw 10.

Bone knot 2 is the supports with supporting capacity 21 that are welded with steel pipe and steel plate, and the height of its bone knot 2 is pressed the calibrated altitude design of broadstep, and it is 2 stacked that a plurality of bones are tied, and is generally 12-15, use with quadrat method fixedly connected, formation pedal keel.Because of its bone knot and bone knot along the steel pipe center, can horizontally rotate, thus can reach the purpose of multidirectional rotation, its rotation direction determine the back earlier fixedly the first order mark time skeleton on the ground, the afterbody bone of marking time is tied and is utilized the steel end plate to be fixed on upper strata crossbeam or the ground to get final product.

Tie 2 outsides at bone and be provided with profile housing 22, the design of profile housing 22 can be consistent with the house fitting style, or design on demand.

In addition, the profile housing of bone knot 2, pedal on the support (stair tread), sideboard, handrail, column, all adopt inorganic composite materials to make, this material prescription can adopt light-burning magnesium powder 40%, magnesium chloride 18%, sawdust 40%, after fully stirring, glass fiber 2% and a small amount of waterproofing admixture insert moulding form, and make steelframe bone knot 2 be in the tram, curing molding gets final product, this material possesses fire prevention, waterproof, mothproof, anticorrosion, can follow closely, can saw, performance such as wear-resisting, its surface is suitable for all kinds of oiling coating and decorates, in order to emphasize wood effect, make pedal, column, during handrail, its surface is cast with the wood grain veinpatterns design that the convex-concave degree of depth is the 0.2-1 millimeter, thereby makes it harmonious with other decoration of room.

But use this inorganic many rotation directions of Dai Mu stair simplified design difficulty, saving takes up room, and beautifies the room class, and batch process can standardize, Site Design is installed, and simplifies difficulty of construction, improves speed of application, reduce cost,, reduce fire and take place for country saves timber resources.
