Description

Technical Field

[0001] The invention relates to the technical field of suspended ceilings, and in particular to a connection structure between a conversion layer and a main structure in a curved suspended ceiling and a construction method. Background Art

[0002] In the current field of building technology, in the curved aluminum ceiling project, especially in the transition layer construction involving the curved aluminum plate and the inclined structure, the traditional construction method mostly relies on the direct steel frame welding on site according to the inclined cylindrical steel structure and the curved aluminum plate transition layer. The main installation method is that the transition layer steel frame is directly welded to the main structure without the use of combined clamps. Subsequently, the transition layer is connected to the aluminum plate through the hanger.

[0003] The disadvantage of the existing practice is that after the transfer layer is directly welded on the main steel structure, it is difficult to adjust the elevation of the transfer layer according to the height difference of the main steel structure on site. After welding, the size of the transfer layer is fixed and lacks room for adjustment, which makes it difficult to accurately control the size of the inclined surface of the surface aluminum plate.

[0004] This method is not only inefficient, but also has a low error tolerance rate, which further increases the complexity of the subsequent aluminum plate ordering and on-site installation. Especially during the installation stage, the gaps between aluminum plates are difficult to control accurately, resulting in unsatisfactory construction results and may even affect delivery. Especially when it comes to the corner treatment between multiple aluminum plates, it is more likely to have problems with height differences and misaligned seams. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects of the prior art and provide a connection structure and construction method between a conversion layer in a curved ceiling and a main structure, so as to solve the problems of low efficiency and low fault tolerance of the existing method.

[0006] The technical solution for achieving the above-mentioned purpose is: a connection structure between the transition layer in the curved ceiling and the main structure, comprising: two groups of grabbing parts, the two groups of grabbing parts are respectively connected to the transition layer, and the two groups of grabbing parts are arranged opposite to each other; a T-shaped connecting part, the T-shaped connecting part is arranged between the two groups of the grabbing parts, and the two sides of the upper end of the T-shaped connecting part are respectively clamped on the two groups of the grabbing parts; a base, the base is horizontally arranged, and the upper end of the base is connected to the bottom end of the T-shaped connecting part; a U-shaped steel plate, the upper end of the U-shaped steel plate is connected to the bottom end of the base, and the inner wall of the U-shaped steel plate is supported on the bottom of the main structure.

[0007] In a connection structure between a transition layer and a main structure in a curved ceiling of the present invention, a grabbing piece is used to connect the transition layer, a U-shaped steel plate and a base are used to support the bottom of the main structure, and the transition layer and the main structure are connected by a T-shaped connecting piece, which can effectively compensate for the error between the main structure and the transition layer during on-site construction, improve construction efficiency, and ensure installation quality.

[0008] A further improvement of the connection structure between a conversion layer and a main structure in a curved ceiling of the present invention is that two square tubes are arranged opposite to each other in the conversion layer, and the connection structure includes: a groove is formed at one end of each group of the grabbing members, and the groove corresponds to the end of the square tube.

[0009] A further improvement of the connection structure between the conversion layer and the main structure in a curved ceiling of the present invention is that the frame structure of the main structure is arranged below the two square passages, and the connection structure includes: the frame structure is connected to the bottom end of the base.

[0010] A further improvement of the connection structure between the transfer layer and the main structure in a curved ceiling of the present invention comprises: a plurality of diagonal bracing angle steels are arranged between the frame structure and the base.

[0011] A further improvement of the connection structure between the conversion layer and the main structure in the arc-shaped ceiling of the present invention lies in that the frame structure is arranged in parallel with the base.

[0012] A further improvement of the connection structure between the transfer layer and the main structure in a curved ceiling of the present invention is that the curvature of the bottom of the frame structure matches and corresponds to the curvature of the U-shaped steel plate.

[0014] A further improvement of the connection structure between the inner conversion layer and the main structure of the arc-shaped suspended ceiling of the present invention lies in that the grabbing piece and the T-shaped connecting piece are connected by bolts.

[0015] A further improvement of the connection structure between the inner conversion layer and the main structure of the arc-shaped suspended ceiling of the present invention is that a plurality of connection holes are provided on the grabbing member for the bolts to pass through.
