Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for installing coffered ceilings. Background Technology

[0002] Modern large-scale public building ceiling decoration styles can generally be divided into five types: flat ceilings, partial ceilings, grid ceilings, coffered ceilings, and irregular-shaped ceilings. Coffered ceilings, as one of these five types, are very popular. Coffered ceilings involve partial ceiling installation around the perimeter of a room, and can be designed as one or two layers. This decoration can increase the feeling of height in the space and also change the lighting effect inside the room.

[0003] However, since most coffered ceilings are now partial ceilings, they are generally installed in smaller indoor spaces, resulting in a smaller workload. They are usually installed manually by small construction teams using measuring tapes, which is a relatively rough construction method and lacks standardized construction control. When coffered ceilings are installed continuously in buildings with larger indoor spaces, it can lead to excessive accumulation of errors, making it difficult to guarantee the construction quality. Summary of the Invention

[0004] To address the problem that existing coffered ceiling construction methods are difficult to apply to continuous coffered ceiling construction projects in buildings with large interior spaces, this invention proposes a coffered ceiling installation method.

[0009] S5~The surveying and layout workers use measuring instruments to measure and record the relative axis elevation dimensions of the top and bottom openings of each caisson unit;

[0010] S6~ transports the horizontal and vertical keels, beam wrapping slabs, and coffered ceiling bottom slabs to the construction site;

[0013] S9~The beam cladding plates are installed on the bottom and both sides of the longitudinal keel, and the algae well bottom plates are installed between the adjacent beam cladding plates, and the construction is completed.

[0014] Preferably, in step S1, after the transverse keel, longitudinal keel, beam cladding plate and algae well bottom plate are prefabricated, the quantity, specification and appearance quality of the prefabricated transverse keel, longitudinal keel, beam cladding plate and algae well bottom plate are pre-inspected one by one, and the plate and rod that do not meet the quality standard are replaced.

[0015] Preferably, before pre-inspecting the algae well bottom plate and the beam cladding plate, the algae well bottom plate and the beam cladding plate are numbered and pre-arranged according to the construction drawing, and then pre-inspected.

[0016] Preferably, in S6, after the transverse keel, longitudinal keel, beam cladding plate and algae well bottom plate are transported to the construction site, the standard degree and uniform degree of the transverse keel, longitudinal keel, beam cladding plate and algae well bottom plate are detected according to the algae well unit record data in S5, and the plate or rod with large deviation is corrected.

[0017] Preferably, before S7 construction, the straightness of the horizontal steel wire is detected and corrected, and then the installation of the transverse keel is started.

[0018] Preferably, after S7 is completed, the straightness of the spliced transverse keel is detected according to the construction drawing and the measurement data in S5, and the transverse keel exceeding the error is corrected.

[0019] Preferably, after S8 is completed, the straightness of the spliced longitudinal keel is detected according to the construction drawing and the measurement data in S5, and the longitudinal keel exceeding the error is corrected.

[0020] Preferably, in S9, the aluminum alloy hanging piece is first installed on the longitudinal keel, and then the beam cladding plate and the algae well bottom plate are fixed on the aluminum alloy hanging piece.

[0021] Preferably, the aluminum alloy hanging piece is a mouth-shaped rod frame extending in the front and back directions, and the aluminum alloy hanging piece is sleeved on the longitudinal keel;
