Auxiliary device for building interior decoration

Abstract

The invention discloses an auxiliary device for building interior decoration, which comprises at least two expansion joints vertically propped between two indoor walls; the transverse rods are fixed between the two telescopic joints and serve as keel supports of the ceiling frame; the vertical rods are fixed between the two indoor wall bodies and serve as another keel support of the ceiling frame; the vertical rods and the transverse rods are arranged in a staggered mode to form the ceiling frame, and the buckle plates are placed in grids of the ceiling frame. A traditional ceiling joist structure is changed, the structure that the telescopic joints abut against the wall faces, and then the buckle plate is installed between the two telescopic joints is adopted, holes do not need to be punched in the wall faces to install supporting angle steel and the like, and the wall faces are protected against damage; the expansion joint can be well and rapidly disassembled and assembled, and construction gas supply for ceiling installation is greatly shortened; the telescopic keel is simple in structure, telescopic, adjustable in length and capable of adapting to indoor spaces of different sizes, labor hours are saved, and the keel installation cost is reduced.
