AI Technical Summary

Technical Problem

When existing floor decking is connected and fixed to the truss, protrusions or holes are often left when it is dismantled, requiring secondary treatment, which affects construction costs and the quality of the building's appearance.

Method used

The structure uses a floor deck and a bracket for fixing. The rubber layer at the bottom of the bracket gradually increases in thickness. An interference fit is used to achieve a stable connection. The elastic recovery of the rubber layer helps to prevent the formation of protrusions or holes. At the same time, annular protrusions and caps protect the connecting components to ensure connection stability and prevent foreign objects from entering.

Benefits of technology

It achieves a robust connection without the need for secondary processing, protects the strength of the concrete surface and the quality of the building's appearance, reduces construction costs and time, and enhances the reliability and reusability of the connection.

Abstract

This application relates to a floor decking and bracket fixing structure, belonging to the field of building formwork technology. It includes a floor decking body, concrete pads, bracket assemblies, connecting assemblies, and a truss body. This application utilizes a design where the locking rod slides along the external threaded pipe, with a gradually thickening rubber layer at its bottom. When inserted into the positioning hole, it tightly adheres to the inner wall for a stable connection. During removal, the elastic recovery of the rubber layer allows for detachment, preventing protrusions or holes from remaining on the surface of the floor decking body and eliminating secondary processing steps. The annular protrusion limiting the locking rod improves connection stability, and the cap prevents foreign objects from falling into the threaded hole, optimizing practical use. The first and second locking slots precisely position the truss body, enhancing overall stability. All components are reliably connected, and there is no damage after removal. This saves construction time and costs while protecting the strength of the concrete surface and the building's appearance quality, making it significantly more practical than traditional connection methods.
