も容易である。According to the present invention, there is provided an inverted groove-shaped ceiling frame (1) formed by a top wall (4) and side walls (5) extending downward from both ends of the top wall, and a pipe penetrating pipe. A substantially rectangular plate-shaped pipe holding member (14) having a hole (16) is provided, the pipe holding member (14) being parallel to the top wall (4) of the ceiling frame (1) and the top wall. The first fixing screw (29) is slidably fitted in the guide groove (15) between the receiving portions (13) extending in opposite directions from the side wall portion (5). The pipe holding member (14) is screwed into the screw hole (22) in the vertical direction of (14) from below, and its tip is pressed against the back surface of the top wall (4) of the ceiling frame (1) to thereby move the pipe holding member (14) to the ceiling frame. The pipe holding member (14) is fixed to the ceiling frame (1) by pressing it against the receiving part (13) of the sprinkler (2). For lighting equipment (41) Wiring, which is used in the wiring or the like for fire alarm equipment (46), further ceiling frame - the pipe through hole of the top wall portion of the beam (1) (4) (6)
And the second fixing screw (34) is passed through the pipe through hole (16) of the pipe holding member (14) and the horizontal screw hole of the pipe holding member (14).
Screw in (24) from outside and insert the tip into a pipe (3,40,45)
The pipe (3, 40, 45) is configured to be fixed to the pipe holding member (14) by pressing the pipe (3, 40, 45) on the outer periphery of the ceiling frame (1). It can be firmly fixed in a stable state without wobbling, and its fixing structure is simple and its fixing work is easy. The present invention also provides the pipe holding member
(14) is further concentric with the pipe through-hole (16) and communicates with the upper opening surface of the through-hole (16) and opens at the upper surface of the pipe holding member (14) to open the pipe (3, 40, 45) has an enlarged hole (18) surrounding it, and the sealing material (35) is in a liquid state in an annular space (19) between the enlarged hole (18) and the pipe (3, 40, 45). By pouring and hardening it to have a soft elasticity, the pipe through hole (16) of the pipe holding member (14) and the pipe (3, 40, 4)
5) It is configured to block the flow of air from the gap between the joining surface and the sealing work is easy,
And the cleanliness of the indoor air is kept high. According to the present invention, furthermore, the pipe through-hole (6) in the top wall (4) of the ceiling frame (1) is formed to have the same diameter as the enlarged hole (18) of the pipe holding member (14), Sealing material is also provided in the annular space (7) between the pipe through hole (6) and the pipe (3,40,45).
(35) is poured in a liquid state and hardened so as to have a soft elasticity so that air is prevented from flowing through a gap between the joint surface between the pipe holding member (14) and the ceiling frame (1). With this configuration, the air cleanliness in the room can be kept higher in addition to the ease of the sealing operation. The present invention also provides that the ceiling frame (1) has an inverted T-shaped groove (8) at substantially the center of the top wall (4) for engaging with the head (11) of the suspension rod (10). An engaging wall portion (9) is continuously provided, and the engaging wall portion (9) is provided.
Since the pipe through-hole (12) concentric with the pipe through-hole (6) of the ceiling frame (1) is also formed, the ceiling frame (1) can be easily suspended and the pipe ( 3,40,45)
The sealing work between the holding frame (14) and the ceiling frame (1) is also easy.
