Embodiment

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

[0032] Such as Figure 4 , Figure 5 As shown, the one-layer reinforced platform 1 includes a 15mm thick steel plate 1 and an L50 angle steel, which is welded horizontally and vertically into a mesh layer, and the angle steel spacing is 300mm (the horizontal and vertical is 300*300mm). The lower layer of the angle steel mesh layer is provided with a wood board, the upper layer is welded with a 10mm thick steel plate, a cement mortar leveling adhesive layer is laid on the second layer of the steel plate, and a 15mm thick steel plate at the support point of the platform is reinforced. The anchor bolt is reinforced and welded with the L50 angle steel to ensure the bearing point of the bearing. The upper part of the steel plate is a cement ...

Abstract

The invention discloses a support-free steel structure spiral staircase, which comprises a reinforced platform (1), stair steps (2), skirting waistline (3), railing handrails (5), the skirting waistline (3) The lower corner is welded to a reinforced platform (1); the stair steps (2) are welded to the skirting waistline (3), and multiple support columns (6) are arranged on both sides of the stair steps (2); The supporting column (6) is embedded in the skirting line (3) and fixed by welding, the supporting column (6) and the skirting line (3) are provided with grooves, the glass guardrail (4) is embedded in the groove, and the railing handrail (5) Fix it on the glass guardrail (4) through the connector. The invention can ensure the load bearing and force requirements, realize the feasibility of support-free technology, reduce the construction period, and reduce the construction difficulty; and can effectively prevent the occurrence of common quality problems caused by unbalanced force and fracture, and control the problem of serious material loss.

Description

Technical field [0001] The invention relates to a spiral staircase with a support-free steel structure. Background technique [0002] At present, for the traditional steel structure spiral staircase installation technology, the traditional installation method is to adopt a large arc and a middle column to support, or design a force part in the middle of the staircase for support, of which the larger arc rotates The stairs occupies a large area and the consumables and the force method are single, and the force part of the middle part of the prop up affects the decorative effect, which does not reflect the decorative grade of the design, destroys the overall coordination and design effect, and affects the steel structure spiral staircase. The construction technology only stays on the basis of simple shape and single force structure. The construction is difficult, the process is complicated and lengthy, and the material loss is serious. [0003] The traditional steel structure spiral...
