Description

Technical Field

[0001] The utility model relates to the technical field of building connection structures, in particular to an adjustable fixing structure of a roof grid. Background Art

[0002] Building roofs, especially Chinese-style building roofs, are equipped with roof grilles with a certain inclination angle. For decorative and aesthetic reasons, the lower end of the roof grille is also equipped with an overhanging eaves. The traditional fixed structure of the roof grille is usually to set a heightened main steel structure on the side of the building roof close to the main body of the building, and fix it by setting connectors and transfer structures between the main steel structure and the roof grille. The transfer structure needs to be designed and molded according to the slope of the roof grille. The transfer structure produced by one mold opening can only be applied to roof grilles with a fixed slope. If the slope of the roof grille changes, the transfer structure needs to be redesigned and molded accordingly to adapt to roof grilles with different slopes, which leads to an increase in the mold opening amount and cost of the profile factory, and also causes an extension of the construction time. Utility Model Content

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned prior art and provide an adjustable fixing structure for the roof grille, which can solve the problem that the traditional fixing structure of the roof grille needs to open the mold multiple times to adapt to roof grilles with different slopes when the slope of the roof grille changes.

[0004] To this end, the utility model adopts the following technical solutions:

[0005] The roof grid is adjustable and fixed in structure, including a main steel structure, a connecting piece, and a transition structure. The transition structure includes a first transition piece, a second transition piece, and an intermediate transition piece. The intermediate transition piece is a cylindrical structure. The first transition piece includes a first arc-shaped connecting part and a first supporting part for connecting the connecting piece. The second transition piece includes a second arc-shaped connecting part and a second supporting part for connecting the roof grid. The inner diameters of the first arc-shaped connecting part and the second arc-shaped connecting part are the same and are both compatible with the outer diameter of the intermediate transition piece. The intermediate transition piece is fixed between the first arc-shaped connecting part and the second arc-shaped connecting part. The second arc-shaped connecting part can rotate around the intermediate transition piece.

[0006] On the basis of adopting the above technical solutions, the present invention can also adopt the following further technical solutions, or use these further technical solutions in combination:

[0007] The first supporting portion is a "concave" shaped structure, and a first hollow portion is provided between the first supporting portion and the first arc-shaped connecting portion. The first supporting portion is fitted with the upper surface of the connecting member below it and the two are fixedly connected by a plurality of bolts, and one end of the bolt is located in the first hollow portion.

[0008] The second supporting portion is a "concave" shaped structure, and a second hollow portion is provided between the second supporting portion and the second arc-shaped connecting portion. The second supporting portion is fitted with the lower surface of the roof grille above it and the two are fixedly connected by a first screw, and one end of the first screw is located in the second hollow portion.

[0009] The first arc-shaped connecting portion is fixedly connected to the intermediate transition piece by a plurality of second screws.

[0010] Both ends of the arc of the first arc-shaped connecting portion extend beyond the first supporting portion.

[0011] The second arc-shaped connecting portion is fixedly connected to the intermediate transition piece by a plurality of second screws.

[0012] Both ends of the arc of the second arc-shaped connecting portion extend beyond the second supporting portion.

[0013] The intermediate adapter is a hollow cylinder.
