Ceiling joist assembly

Abstract

The invention belongs to the field of indoor integrated ceiling decoration, and particularly relates to a ceiling joist assembly. The ceiling joist assembly comprises a main joist, a triangular joist and hanging rod installation holes, and is characterized in that the triangular joist is composed of a triangular joist top plane, two symmetrical triangular joist side faces and a bottom groove, the main joist comprises an upper plate, a lower plate and a middle plate, the hanging rod installation holes are formed in the upper plate of the main joist, 45-degree overturn hanging buckles and perpendicular overturn hanging buckles are arranged on the middle plate and are arranged in an alternate mode, the arc-shaped bending direction of each 45-degree overturn hanging buckle and the arc-shaped bending direction of the adjacent perpendicular overturn hanging buckle are opposite, and every two adjacent 45-degree overturn hanging buckles or every two adjacent perpendicular overturn hanging buckles are in the same shape. The ceiling joist assembly has the advantages that the varieties of installation materials are reduced, installation can be conveniently achieved, various hanging pieces and the main joist are integrated, and the situation that the hanging pieces are pulled straight when bearing too large force or bearing force for a long time can not occur.

Description

technical field [0001] The invention belongs to the field of indoor integrated suspended ceiling decoration, and in particular relates to a hanging item keel assembly. Background technique [0002] During the interior decoration of the house, the ceiling will be decorated with a suspended ceiling. A good and reasonable suspended ceiling design can make up for the shortcomings of the original building structure, such as being too high and too wide. Thermal insulation and other effects. The traditional integrated suspension keel structure is difficult to meet the needs of multi-level ceilings. When encountering special roof structures, for example, the roof is relatively high, there are many columns and girders, and the turning cannot be handled. When air conditioners, bathroom heaters, and sprinkler equipment affect the ceiling structure, Large changes or even reinstallation are required, and the installation of ceilings or electrical appliances is very inconvenient. The in...

Problems solved by technology

In the current existing technology, the ceiling installation of the integrated suspension item mainly uses the connection and fixation of the light steel keel and the triangular keel to complete the keel frame structure. It is time-consuming and laborious to install during the installation process. There are many kinds of auxiliary parts such as triangular hanging parts and main bone hanging parts, and the stability of the frame structure after installation is not enough. The design of the suspended ceiling will be greatly restricted, and it cannot fully meet the various requirements of customers. It is very difficult to disassemble and refit. inconvenient

[0003] China CN202370146U provides an installation structure for an integrated ceiling keel, including a main triangular keel, an auxiliary triangular keel, a connecting piece, a hook, and a screw. In the elastic chamber, the connecting piece is provided with a first connecting hole for the auxiliary triangular keel to be inserted, and the hook is provided with a second connecting hole for the main triangular keel to be inserted, and the first elastic safety piece and the second elastic safety piece are added. The first elastic safety piece is stuck between the auxiliary triangular keel and the connecting piece, the U-shaped mouth of the first elastic safety piece is stuck outside the arc edge at the end of the main triangular keel elastic cavity, and the elastic cavity is locked, and the second elastic safety piece is stuck Between the main triangle keel and the hook, although the overall stability and firmness have been improved, the required auxiliary parts have been reduced to a certain extent, and the cost has been saved, but a large number of hanging parts are still used, and there is no fundamental solution The complexity of the installation of the integrated ceiling keel, and because the hanger is easy to be straightened, the stability and firmness of the keel need to be further improved
