A three-dimensional recessed keel structure and assembly thereof

Abstract

The utility model relates to the technical field of building keel, disclose a kind of three-dimensional recess keel structure and its assembly, the bottom recess is established in the bottom of main keel;The top of main keel is equipped with main keel clamping groove, main keel is equipped with connecting assembly by main keel clamping groove, and main keel is connected between suspended ceiling frame by connecting assembly between connection.This utility model adopts unique structure design, the reverse trapezoidal structure of main keel clamping groove and the upper and lower connecting bottom plate of connecting assembly are closely matched, and multiple fastening bolts are evenly distributed and fastened connection, and the connecting strength of main keel and connecting assembly is strengthened.Meanwhile, inside connecting assembly is restricted by connecting rod, limiting groove, limiting threaded rod and other components, effectively prevent relative displacement and shaking between components, so that main keel, connecting assembly and suspended ceiling frame form stable whole, significantly improve the stability of suspended ceiling connection, avoid the problem that traditional connection mode is prone to loose and large gap.
