Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0013] See also Figure 1 , an embodiment of the present invention provides an operating room air supply ceiling installation method, comprising: S1. Reasonably design the position of the air supply ceiling 1 according to the layout of the operating room, and set the hanger 3 on the concrete floor 2 based on the designed position and the structure of the air supply ceiling 1.

[0014] In practice, the hanger 3 is in an inverted L-shape or a T-shape, and the process of setting the hanger 3 on the concrete floor 2 includes: After the structural reinforcement of the concrete floor 2 is tied, the installation position of the hanger 3 is determined based on the designed position and the structure of the air supply ceiling 1; Tie and fix the top cross bar in the hanger 3 to the structural reinforcement at the determined installation position; The concrete floor slab 2 is supported by a formwork, and a through hole is reserved at the position of the hanger 3 in the middle of the formwork so that the hanger can pass through the through hole; After the concrete floor 2 is formed, a rubber sleeve is placed on the hanger 3 and the rubber sleeve is inserted into the hole to prevent leakage, and concrete is poured to embed the hanger 3 in the concrete floor 2.

[0015] In this implementation, the hanger rod 3 is connected to the structural steel bars in the concrete floor slab 2 as a whole and is pre-embedded in the concrete floor slab 2, which greatly improves the installation strength of the hanger rod 3.

[0016] S2. According to the designed position and structure of the air supply ceiling 1, a diagonal line of the air supply ceiling 1 is laid out on the concrete floor slab, and a hanging rod is respectively arranged on the concrete floor slab 2 at a certain distance outside the two ends of the diagonal line.

[0017] S3. Fix two hand hoists 4 on the provided hanging rods respectively.

[0018] During implementation, the suspension rod can be fixed with expansion bolts. When the expansion bolts are fixed on the concrete floor, a hanging ring can be tied to the expansion bolts with wire, and the hanging ring can be pressed against the concrete floor 2 with the nut on the expansion bolt to ensure a firm connection, and the hand winch 4 is hung on the hanging ring.

[0019] The hanging rod can also be made of a U-shaped ring, which is also fixed in the concrete floor by pre-embedded means. When fixing, the U-shaped ring is tied and fixed to the structural steel bars of the concrete floor. When the concrete floor is supported by formwork, a long hole is reserved at the position of the U-shaped ring. After the U-shaped ring passes through the long hole, a rubber plug of a suitable shape is used to seal the long hole, and concrete is poured after sealing.

[0020] S4, fix a set of diagonal parts of the air supply ceiling 1 to the lifting chain of the hand chain hoist 4, such as Figure 2 As shown, the manual chain of the hand chain hoist 4 is pulled synchronously and slowly to ensure that the air supply ceiling 1 is lifted smoothly and slowly.

[0021] During the actual hoisting process, workers can hold a push rod against one side of the air supply ceiling 1 to improve the hoisting stability.

[0022] S5, when the air supply ceiling 1 is lifted to the lower side of the suspension rod 3, the position of the air supply ceiling 1 is adjusted so that the mounting hole in the air supply ceiling 1 is aligned with the suspension rod 3; S6. After the air supply ceiling 1 is raised to the designed elevation, Figure 3 As shown, a nut is screwed into the suspension rod 3 to fix the air supply ceiling 1. After the fixing is completed, the hand chain hoist 4 is removed. At this point, the installation of the air supply ceiling 1 is completed.

[0023] During implementation, when the air supply ceiling 1 needs to be maintained or replaced, the hand winch 4 is fixed on the set hanging rod, and the lifting chain of the hand winch 4 is fixed to a set of diagonals of the air supply ceiling 1. The nuts on the suspension rod 3 are slowly loosened in a diagonal manner so that the lifting chain gradually bears the weight. After the nuts on the suspension rod 3 are completely removed, the manual chain of the hand winch 4 is slowly pulled synchronously to lower the air supply ceiling 1 smoothly and slowly to the ground.
