Embodiment

[0031] Example: such as figure 1 , figure 2 , image 3 Shown: a support-free steel structure spiral staircase, which includes a reinforced platform 1, stair treads 2, skirting waistline 3, glass guardrail 4, railing handrail 5, support column 6.

[0032] Such as Figure 4 , Figure 5 As shown, one layer of reinforced platform 1 includes 15mm thick steel plate 1 and L50 angle steel. The angle steel is welded horizontally and vertically to form a mesh layer, and the angle steel spacing is 300mm (300*300mm horizontally and vertically). The lower layer of the angle steel mesh layer is equipped with a woodworking board, and the upper layer is welded with a 10mm thick steel plate 2. On the second layer of the steel plate, a cement mortar leveling and pasting layer is laid. Anchor bolts are reinforced and welded with L50 angle steel to ensure the force support of the bearing point. The upper part of the steel plate is a cement mortar leveling adhesive layer, and the surface of t...

Abstract

The invention discloses a non-support steel-structure spiral staircase comprising a first-layer reinforcing platform (1), stair steps (2), skirting waist lines (3) and handrails (5). The lower corners of the skirting waist lines (3) are welded to the first-layer reinforcing platform (1). The stair steps (2) are welded to the skirting waist lines (3). Two sides of the stair steps (2) are provided with a plurality of supporting columns (6). The supporting columns (6) are embedded in the skirting waist lines (3) in a weld fixing manner and are provided with grooves with the skirting waist lines (3). Glass guardrails (4) are embedded in the grooves. The handrails (5) are fixed on the glass guardrails (4) through connectors. The non-support steel-structure spiral staircase has the advantages that force bearing requirements can be guaranteed, non-support technical feasibility is realized, construction period is shortened, and construction difficulty is reduced; the quality defects of break due to unbalanced force bearing can be prevented effectively, and the problem that material consumption is high is controlled.

Description

technical field [0001] The invention relates to a support-free steel structure spiral staircase. Background technique [0002] At present, for the installation technology of the traditional steel structure spiral staircase, the traditional installation method is to use a large arc and support it with a column in the middle, or design a force-bearing part in the middle of the staircase to support it, and the rotation with a large arc Stairs occupy a large area and have single consumables and force-bearing methods, and the force-bearing part propped up in the middle affects the decorative effect, does not reflect the decorative grade of the design, and destroys the overall coordination and design effect. The advanced construction technology only stays on the basis of simple shape and single stress structure. The construction is difficult, the process is complicated and lengthy, and the material loss is serious. [0003] The installation of traditional steel structure spiral s...
