Description

Keel connecting structure for grid suspended ceiling

Technical Field

The utility model relates to a furred ceiling technical field, in particular to fossil fragments connection structure that grid furred ceiling was used.

Background

The grid suspended ceiling has the advantages of clear level, strong stereoscopic impression, novel structure, fire prevention, moisture prevention, good ventilation and the like, is suitable for suspended ceiling decoration in places such as various superstores, leisure clubs, bars, airports, office buildings and the like, and is favored.

Grid furred ceiling is fixed many vertical jibs on indoor roof usually in the installation, then, sets up at jib tip and hangs the piece, and the rethread bolt or screw are fixed the main joist on hanging the piece to realize the installation of main joist. And then the auxiliary keel and the grid unit are assembled on the main keel through bolts. However, the installation method using bolts or screws is troublesome, and it is inconvenient for an operator to install the keel and the ceiling, which takes a lot of time. And the main keel, the auxiliary keel and the grid unit are usually not on the same layer, which affects the appearance and occupies a large amount of space. In order to solve the problem, the chinese patent CN204139417U adopts the concept that the main keel has an inverted U-shaped cross section, the grating slat has a U-shaped cross section, and the two sides of the U-shaped opening are formed with access structures adapted to the slot structures. Adopt slot structure and access structure fixed connection between grid slat and the main joist, compare with traditional screw fixation mode and have the installation effectiveness high, dismantle advantages such as convenient, but main joist and grid slat are still at two layers, and fixed mode is unstable, under the grid action of gravity, have the possibility that takes place to drop.

In addition, the whole top network of the grid suspended ceiling can be independently disassembled and assembled by the small grids, and the design ensures that the ceiling is very convenient for air conditioning, fire protection and maintenance of other pipes and electrical appliances. However, the small square grids are not suitable for special-shaped roof structures, and can only be used for sawing keels on site if oblique angles are met, and the small square grids need to be matched by multiple persons during installation, so that time and labor are wasted.

In a word, the main problem that current grid suspended ceiling's fossil fragments connection structure exists is: 1. the main keel needs to be installed firstly, the auxiliary keel and the grid unit need to be installed, cooperation of multiple persons is needed in the installation process, operation is complex, and time and labor are wasted. 2. When encountering a special-shaped structure, the grid small square is not suitable, and the keel needs to be sawed on site according to the actual shape, which is very inconvenient. 3. The existing main keel and the grid unit are arranged in an upper layer and a lower layer, so that the appearance is influenced, and the space is wasted.

In view of this, the invention provides a keel connecting structure which is simpler in structure, simpler and more convenient to operate, saves time, and is suitable for a special-shaped structure and attractive in appearance.
