摘要： A freestanding, adjustable, modular spiral staircase embodied in a unique method of spiral staircase design is provided. The steps of the spiral staircase are arrayed and supported in a circular pattern around a central column with the outside edges or leading or trailing corners of the steps are supported by three peripheral columns, while step posts interconnect adjacent steps. Many parts are interchangeable and the steps adjustable to allow for shortening or lengthening the staircase. The base of the staircase unit is heavy to provide maximum stability and to prevent tipping.

摘要： Described herein are systems and methods of manufacturing a spiral staircase assembly for custom projects. A method may include coupling a plurality of stairs to a center column such that distances between adjacent stairs of the plurality of stairs deviates less than ½″ to meet code. A method may further include cutting the center column after coupling the plurality of stairs to the center column to form a first center column and a second center column. A method may further include welding a female column coupling to a first end of the first center column and welding a male column coupling to a first end of the second center column. The male column coupling is configured to couple to the female column coupling such that when the male column coupling is coupled to the female column coupling, distances between adjacent stairs of the plurality of stairs deviates less than ½″.

摘要： A kit of parts for securing a plurality of fixtures to an elongate support member is described. The kit of parts comprises a plurality of attachment members. Each attachment member comprises an aperture for receiving the elongate support member and a fixing detail adapted to attach a fixture to the attachment member. The aperture is larger than a lateral dimension of the elongate support member to provide a gap between the attachment member and elongate support member when received in the aperture. The kit of parts also comprises a plurality of locking elements. Each locking element is adapted to be received in the aperture in the gap between the attachment member and the elongate support member to secure the attachment member to the elongate support member by friction. Further, each attachment member is adapted to engage an adjacent attachment member when secured to the elongate support member by at least one said locking element to form a hollow column secured around the elongate support member for supporting a plurality of fixtures.

摘要： A step for modular staircases, preferably produced by moulding using a thermoplastic technopolymer, comprises at least a main body (11) and a spacer (12). The main body (11) comprises at least a tread surface (Ha) and a hollow portion (lib) extending vertically with an internal thread (111), whilst the spacer (12) has an external thread (121) matching that of the hollow portion (lib) of the main body (11), allowing the spacer (12) and the hollow portion (lib) to be screwed together The hollow portion (lib) and the spacer (12) also have ends (112,122) which do not interact, shaped to match one another, to allow vertical stacking of two or more steps (10), thus obtaining a modular staircase (1), complete with a landing (20) produced in a similar way to the step (10).

摘要： A do-it-yourself spiral staircase has a central column (1) made of a hollow steel tube or pipe, which extends between a support (2; 7; 16) on a lower floor and a landing plate or end tread (3) on an upper floor of a residence or office building. The individual treads (4) are distributed along the column between spacer sleeves (5; 5'). The steel tube or pipe is divided into two tubular sections, of which one tubular section (11; 15; 15'; 20) has an excess length and can be shortened at its free end for adjustment to the required height of the spiral staircase to the size required at the construction site, whereas the other, ready-made tubular section (10; 18) is telescopically attached to the tubular section which has been shortened. At least two mutually aligned or registering bores are provided. Each bore passes radially through its respective telescopically engaging tubular parts. A highly hardened locking pin or split sleeve (14; 14') is driven or pressed into the aligned bores to provide an elastic bias to securely connect both tubular sections with each other at the construction site.
