Description

A clip-on keel connector

technical field

The utility model belongs to the technical field of architectural decoration, and relates to an integrated suspended ceiling installation system, more specifically to a clamping type keel connector.

Background technique

The keel referred to in the field of architectural decoration technology is a building material used to support the shape and fix the structure, and is mostly used as the skeleton and base material of the suspended ceiling in interior decoration. The indoor ceiling adopts the keel and gypsum board structure system. There are suspenders fixed at a certain distance below the roof surface. Because the keel is provided with a snap-in groove, it is used to connect the triangular keel through a connecting piece, so it is also called a snap-in keel. The so-called triangular keel is a long strip-shaped member whose cross section is similar to an inverted hollow triangle, and the lower corner is disconnected. During installation, the clip-type keel is clamped to the connector, and the connector is provided with a groove that can accommodate the triangular keel. The triangular keel passes through the groove, and the left and right slopes of its triangular cross-section form a hanging rib, which is hung on the On the side wall of the groove, the triangular keel is suspended under the clip-type keel; the ceiling decorative panel, also known as the decorative panel, its frame is fixed in the cavity of the triangular keel.

Chinese patent document "CN204804142U", on November 25, 2015, disclosed "a triangular keel connection structure", including a triangular keel and a keel pendant, the keel pendant includes a base plate and a connecting plate, and a card slot is provided on the connecting plate, and The triangular keel in the card slot is fixedly connected to the installation station through the connecting strip on the keel hanger. The keel hanger proposed by this technical solution is the keel connector, and its disadvantage is that it needs to be fixed separately, and its structural strength is not good. In the existing integrated ceiling structure, the use of keel connectors is relatively large, and the installation efficiency of the keel connectors that need to be fixed is obviously not satisfactory. The triangular keels are designed to be parallel to each other. This determines that the 4 sides of the veneer can only be hung on the triangular keel with one pair of sides to support the weight of the veneer itself. When mounting heavy decorative panels and ceiling appliances such as lamps, ventilation fans, and bathroom heaters, the firmness and safety are affected, which brings great inconvenience to the installation of integrated ceilings. In the absence of major technological breakthroughs in the integrated ceiling structure, it is necessary to improve the overall strength of the structure, especially the connection strength between the triangular keel and the clip keel, and between the triangular keel and the frame of the veneer.

Contents of the invention

The technical problem to be solved by the utility model is that the structure of the existing keel connector is complex and the strength is not good, thereby providing a snap-fit keel connector and its construction method, which has a simpler structure, is safer and more reliable, and has better strength .

In order to achieve the above purpose, the utility model adopts the following technical scheme: a clip-on keel connector, including a part connected to the clip-type keel and a part connected to the triangular keel, the keel connector is provided with a horizontal block, and the horizontal block A pair of sides are respectively provided with vertical upward vertical blocks, and the upper end of the vertical blocks is bent inward to form a card slot adapted to the tongue-and-groove opening of the clip-type keel; the other pair of horizontal blocks are respectively provided with a pair of downward bending The hanging blocks, each pair of hanging blocks form a triangular keel hanging groove suitable for the cross-sectional shape of the triangular keel.

In order to improve the structural strength between the triangular keel and the cassette keel, the keel connector is redesigned in this technical solution. The keel connector includes a horizontal block. The upper part of the horizontal block is designed to be used to clamp the structure of the snap-type keel. It includes a pair of vertical upward vertical blocks. The tongue and groove of the clip-type keel; the lower part of the horizontal block is designed to connect the structure of the triangular keel, including two pairs of hooking blocks, and a triangular keel hanging groove adapted to the cross-sectional shape of the triangular keel is formed between each pair of hooking blocks , so that the triangular keel can pass through the mounting groove smoothly, and the hanging rib of the triangular keel can just hang on the mounting block. After such a design, the card-type keel and the triangular keel are connected together at right angles by the keel connector, and the keel connector will not be twisted due to force, which will eventually cause the card-type keel and the triangular keel to be pulled and twisted and lose their due strength. In the overall structure of the suspended ceiling, such a design can provide better strength without adding parts.

Preferably, the number of rebates adapted to the distance between the card slots is not less than 2. It is recommended that the spacing should not be less than 2 tongue and groove lengths to increase strength.

Preferably, the horizontal block is also provided with an inner block; the thickness of the inner block is adapted to the gap between the two sides of the clip keel. In this scheme, the inner stopper is arranged between the two sides of the cassette keel. After the longitudinal positioning is realized by tongue-and-groove clamping between the keel connector and the snap-in keel, this scheme further performs horizontal positioning between the keel connector and the snap-in keel.

Preferably, the inner stopper includes sidewalls of the inner stopper respectively in contact with the two sides of the clip keel, and a compression elastic element abuts between the sidewalls of the two inner stoppers. When using the scheme of setting the inner block between the two sides of the cassette keel, the elastic element in this scheme will support the gap between the side walls of the inner block, so that the side wall of the inner block and the inner wall of the side of the cassette keel An interference fit is formed between them, which strengthens the positioning effect to a greater extent.

A clip-on keel connector of the utility model has simple structure, ingenious design, and reasonable layout. Only the parts themselves can be effectively connected by clipping, and the auxiliary fixing parts of the traditional keel connector are omitted. Faster installation. At the same time, the clip-on keel connector is structurally designed to intersect the clip-on keel and the triangular keel, which largely avoids the possibility of distortion of the structural parts and provides better strength.

To sum up, the beneficial effects of the utility model are: the structure is simpler, safer and more reliable, and has better strength.
