Abstract
The utility model relates to a novel groove-shaped keel device, which comprises a primary keel and a secondary keel which are connected by a plug structure; the primary keel and the secondary keel are respectively bent by one plate into a structure which is subsequently provided with a ceiling, a connecting rib, a splint, and a T-shaped cross section; the upper end surface of the splint of the secondary keel is provided with a first back-bending groove along the length direction, and the upper end surface of the splint of the primary keel is provided with a second back-bending groove along the length direction; and a position on the splint of the primary keel in which the secondary keel is plugged is further provided with a third back-bending groove which is matched with the first back-bending groove. The primary keel or the secondary keel is bent by the plate, the cost is low, and the process is simple. The secondary back-bending groove of the primary keel and the third back-bending groove of the secondary keel are matched at a corresponding position on the plug structure; and the ceiling hanging effect is better if the novel groove-shaped keel device is used to hang the ceiling in a crossed way.
Description
Technical field
The utility model relates to a kind of new grooved keel device.
Background technology
As shown in Figure 1, original grooved black line baking vanish keel by the 9 common compactings of a slice color coating steel band 6 and a slice galvanized steel strip form, cost height, technology trouble.In addition, the black line in original grooved black line baking vanish keel is by in the keel forming process, and pitch-dark scrawling formed at the external surface of coloured coating steel band 6 upper surfaces 7 upper grooves 8.As shown in Figure 2, original grooved black line baking vanish keel are behind furred ceiling, and the black line 8 of main joist and secondary joist infall is to disconnect mutually, can not connect, and has had a strong impact on the attractive in appearance of furred ceiling.Finishing is being required more and more higher today, and original grooved black line baking vanish keel can not satisfy user's requirement far away.
The utility model content
The technical problems to be solved in the utility model provides that a kind of cost is low, technology is simple, and black line keel device attractive in appearance.
In order to address the above problem, the utility model provides a kind of new grooved keel device, comprise the main joist and the secondary joist that connect by connected structure, described main joist and described secondary joist are respectively by what the bending of sheet material formed has furred ceiling successively, the cross section of dowel and supporting plate is the structure of T-shape, be provided with the first back bending groove along its length in the supporting plate upper surface of described secondary joist, be provided with the second back bending groove along its length in the supporting plate upper surface of described main joist, also be provided with the 3rd back bending groove that matches with the described first back bending groove in the position of the described secondary joist of pegging graft on the supporting plate of described main joist.
Preferably, described connected structure comprises and is arranged on the gap on the main joist and is arranged on projection on the secondary joist.
Preferably, the width of the described first back bending groove, the second back bending groove and the 3rd back bending groove all equates.
The utlity model has following advantage:
1, the utility model main joist and secondary joist adopt all that the bending of sheet material forms, cost is low, technology is simple;
2, the 3rd back bending groove of second back bending groove of main joist and secondary joist mates on the connected structure relevant position in the utility model, when using the utility model to intersect furred ceiling, and the furred ceiling better effects if;
3, connected structure of the present utility model comprises the projection of the gap and the secondary joist of main joist, and it is simple, reliable to peg graft;
4, the width of the first back bending groove, the second back bending groove and the 3rd back bending groove all equates in the utility model, makes two keel more attractive in appearance when intersecting.
