During hoisting, use flexible red webbing to bind the unit components, and prevent the steel wire rope from directly contacting the stainless steel surface to prevent indentation and scratches. Fit the connecting pipe 3 of the decorative round tube 1 onto the positioning piece to complete the positioning of the decorative round tube 1. Adjust the decorative round tube 1 so that the connecting groove of the decorative round tube 1 coincides with the sliding groove of the positioning block. Insert the adjusting screw into the connecting groove and the sliding groove, and adjust the decorative round tube 1 along the extension direction of the sliding groove to adjust the... The spacing between the decorative round tube 1 and the spiral staircase 2 allows the construction workers to adjust the decorative round tube 1 according to the drawing requirements, making the arrangement of several decorative round tubes 1 more layered. After the decorative round tubes 1 are installed, the fixing nuts can be screwed on both sides of the decorative round tube 1. By screwing the fixing nuts, the fixing nuts on both sides of the decorative round tube 1 clamp the connecting pipe 3 to prevent the decorative round tube 1 from shaking during subsequent use. Then, each of the decorative round tubes 1 is installed in sequence to complete the decoration of the spiral staircase 2.

[0030] Furthermore, the bottom of the connecting pipe 3 has an opening, which makes it convenient for construction workers to install the connecting pipe 3 on the fixing block.

[0031] Furthermore, the connector 5 is provided in two rows. After the connector 5 is installed, a decorative panel is provided. When installing the connector, the two connectors are respectively placed on the upper and lower parts of one side of the spiral staircase in its suspended state, and the decorative panel is placed between the two connectors 5 placed vertically. Preferably, the decorative panel is fixed to the connector 5 by welding or by bolts. Weather-resistant neutral silicone sealant is applied at the junction of the decorative panel and the connector 5. The sealant is a stainless steel-specific adhesive of the same color to ensure overall waterproofness. The decorative panel can be an aluminum plate.

The decorative round tube 1 is hoisted to the predetermined installation position using hoisting equipment. During hoisting, flexible red webbing is used to bind the unit components, and direct contact between the steel wire rope and the stainless steel surface is prohibited to prevent indentations and scratches. The connecting pipe 3 of the decorative round tube 1 is fitted onto the positioning component to complete the positioning of the decorative round tube 1. The decorative round tube 1 is adjusted so that the connecting groove of the decorative round tube 1 coincides with the sliding groove of the positioning block. The adjusting screw is inserted into the connecting groove and the sliding groove, and the decorative round tube 1 is adjusted along the extension direction of the sliding groove to adjust the decorative round tube. The distance between the decorative tube 1 and the spiral staircase 2 allows the construction workers to adjust the decorative tube 1 according to the drawing requirements, making the arrangement of several decorative tubes 1 more layered. After the decorative tubes 1 are installed, the fixing nuts can be screwed on both sides of the decorative tube 1. By screwing the fixing nuts, the fixing nuts on both sides of the decorative tube 1 clamp the connecting pipe 3 to prevent the decorative tube 1 from shaking during subsequent use. Then, each decorative tube 1 is installed in sequence to complete the decoration of the spiral staircase 2.
