Concrete embodiment

With reference to each accompanying drawing, the suspension type light steel paired joist that is the U font for cross section, the dual-side of rider keel generally is used for cooperating and hangs in the corresponding screens in main joist dual-side lower edge, the utility model is roughly the same with prior art interconnecting on the mode of major and minor keel, and its main improvement is on the finishing bottom surface of rider keel U font cross section.

Make up metope in order directly to carry dalle, as when making up ceiling, the utility model is specially on the finishing face of the base of rider keel U font cross section formation, be on the finishing bottom surface 11 of common described rider keel 3, be provided with the integrally formed buckling plate 2 in a plurality of and described finishing bottom surface at interval in an orderly manner, this buckling plate is when making, can directly rely on the finishing bottom surface that the dash area punching press among Fig. 2 is sheared and form, make buckling plate pass through its joint face (or fillet) and keep being connected getting final product with the finishing bottom surface.After the punching moulding, the feasible finishing bottom surface and the joint face of buckling plate, longitudinal section such as Fig. 1 or shown in Figure 3 of bearing surface, be the zigzag structure, that is to say, buckling plate is  shape with the vertical sectional shape of the bearing surface 22 of the joint face 21 of fitting up the bottom surface, buckling plate, so just can utilize the bearing surface of buckling plate directly to carry dalle.Need to prove that described zigzag,  shape structure only are the convenience in order to narrate; concrete structure or shape obviously are not absolute strictness; even, the bearing strength that guarantees buckling plate leaves the chamfering round edge for should making the knuckle place of zigzag,  shape; buckling plate is also non-absolute parallel with the finishing bottom surface of rider keel, and the minor variations of these details certainly should be still within protection domain of the present utility model

For light-duty colloid dalle, as the PVC decorative board material, its cross sectional shape can customize arbitrarily, in order to cooperate, bring into play advantage of the present utility model better, can be with reference to Fig. 3 and Fig. 4, the cross sectional shape that is dalle 5 is: an end has groove, and the top 51 of groove can cooperate button to inject on the buckling plate bearing surface 22 of rider keel 3; The other end 53 is thin slightly, can be plugged in the groove of next dalle and carries in the bottom 52 of next dalle groove, and overlap joint forms the ceiling surface of a gapless mutually according to this.

With reference to Fig. 4, in order to make that dalle can be not only convenient but also carry securely in buckling plate, the utility model makes the middle part 221 of the bearing surface 22 of buckling plate swell slightly especially, the finishing identity distance that makes the front end of buckling plate bearing surface 22 and rider keel is from more bigger, so that the groove top of PVC decorative board material can be directed when mounted and successfully insert in the buckling plate, that is to say, the vertical sectional shape of bearing surface roughly is  or ⌒ shape structure, the advantage of this structure also has: when the groove top of PVC decorative board material was all carried on buckling plate, the middle part of swelling slightly on the buckling plate can clamp the PVC decorative board material more securely, on the finishing bottom surface attached to rider keel.

In the accompanying drawing 2 of the present utility model, the face profile shape of above-mentioned buckling plate presents square or rectangular shape, obviously, the cross section structure of the finishing bottom surface of buckling plate and rider keel relation can strike out other different contour shapes according to user's hobby, as long as all can reach improvement purpose of the present utility model and design function as mentioned above.

Because the sheet material of light steel paired joist itself is thinner, has certain elasticity and plasticity, button bit Plate up, down all can be twisted certain amplitude around joint face, therefore making, punching press, When shearing buckling plate, preferably buckling plate is arranged on equidistantly on the described finishing bottom surface advantage Easy to make and cost lower, if do not need to use some button bits on the finishing bottom surface Plate can be when installing the PVC decorative board material, this buckling plate manually up turned round got back to false keel The inside of U font cross section get final product, very convenient. The utility model is particularly suitable for using The light-duty colloid of PVC is decorated the occasion that sheet material makes up ceiling, and is not difficult to find out that it is dismantled also Quite save trouble, make things convenient for.
