Description

Technical Field

[0001] This utility model belongs to the field of steel structure ceiling structure, and specifically relates to a rhomboid grid steel structure ceiling transition layer structure. Background Technology

[0002] In modern architecture, large suspended ceiling structures are widely used in roof systems for high-ceilinged spaces, while interior ceiling decoration is generally carried out through transfer layer structures.

[0003] The existing technology can be referred to the patent with announcement number CN211286250U, which discloses a ceiling transition layer structure. It is fixed to the bottom of the building by a hanging column 20, and a grid frame is fixed below the hanging column to form a transition layer. For concrete roof structures, it is fixed by embedded parts 10. However, for steel structure roofs, the hanging column is directly welded to the steel beam of the steel structure, which has the disadvantages of difficult overhead welding construction and low structural strength. Utility Model Content

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rhomboid grid steel structure ceiling transition layer structure, including steel beams, top keel, vertical keel, horizontal keel, beam side closing main keel and beam side closing secondary keel. The top keel is fixedly welded to the top of the steel beam, the vertical keel is fixedly welded to the top keel and extends downward to the bottom of the steel beam, the horizontal keel is fixed at the bottom of the vertical keel below the steel beam, the beam side closing main keel connected to the steel beam is fixed on the vertical keel near the steel beam, the beam side closing secondary keel is fixed at the bottom of the beam side closing main keel, the beam side closing secondary keel is fixed with a hook, the top of the hook is fixed to the beam side closing secondary keel with screws, the bottom of the hook is fixed to the threaded hanger with a nut, and the threaded hanger is fixed through the horizontal keel.

[0006] By adopting the above technical solution, this application sets a top keel on the top of the steel beam, and the top keel and vertical keel are pre-welded. Then the top keel is welded to the steel beam, changing the overhead welding to the downward welding, which greatly reduces the construction intensity. In addition, the arrangement of the main keel and the secondary keel at the beam side end makes the overall stability higher and has better practicality. Honeycomb aluminum panels can be installed under the horizontal keel, and aluminum single panels can be installed under the secondary keel at the beam side end.

[0007] Preferably, the steel beams form a prismatic structure, and the top keel is arranged along the width direction of the prismatic structure.

[0008] By adopting the above technical solutions, the steel structure can be customized in shape, and the arrangement of the top keel can be made reasonable.

[0009] Preferably, a number of reinforcing longitudinal keels are provided between the horizontal keels. The reinforcing longitudinal keels include intermediate longitudinal keels perpendicular to the horizontal keels and beam-side longitudinal keels parallel to the steel beams, thereby forming three reinforcing longitudinal keels on the inner side of each rhombus. The reinforcing longitudinal keels are welded to the reinforcing horizontal keels.

[0010] By adopting the above technical solution, the three reinforced longitudinal keels connect the transverse keels, giving the whole structure a high degree of integrity and stability.

[0011] Preferably, the top of the main keel at the beam side closing point and the vertical keel are reinforced with diagonal bracing.

[0012] By adopting the above technical solution, the structural strength of the main keel and vertical keel at the beam side closing is improved.

[0013] Preferably, two rows of secondary beam-side joists are provided between the main beam-side joists and the top aluminum single-panel beam-side joists.

[0014] By adopting the above technical solution, the stability of the aluminum plate installed below the main keel at the beam side is high.

[0015] Preferably, the top keel, vertical keel, horizontal keel, main keel at the beam side, and secondary keel at the beam side are all square tubes.

[0016] By adopting the above technical solution, the materials are readily available and the structure has high strength.

[0017] The beneficial effects of this utility model are reflected in the following: This application sets a top keel on the top of the steel beam, and the top keel and vertical keel are welded in advance. Then the top keel is welded to the steel beam, which changes the overhead welding to the downward welding, greatly reducing the construction intensity. In addition, the arrangement of the main keel and the secondary keel of the beam side closing makes the overall stability higher and has better practicality. Honeycomb aluminum panels can be installed under the horizontal keel, and closing aluminum panels can be installed under the secondary keel of the beam side closing.
