DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded ceiling for hanging and supporting a ceiling-mounted air conditioner, a ceiling-mounted lighting fixture, a ceiling-mounted duct, and the like to a girder member above a ceiling finishing material. The present invention relates to a hanging device such as a type air conditioner.

[0002]

2. Description of the Related Art Conventionally, when a ceiling-mounted air conditioner is suspended and supported on a girder member above a ceiling finishing material, for example, a long member 1 having an open lower end as shown in FIGS. The two long members 1 are arranged in parallel with each other, and both ends of each long member 1 in the longitudinal direction are placed on lower end flanges 3 and 3 of girders 2 and 2 such as H-section steels. The upper end of the total threaded rod 5 is connected to two appropriate positions in the length direction of the member 1 via the nut member 4, and the lower ends of the four total threaded rods 5 are extended from the ceiling embedded type air conditioner 6 by the bracket 7. Insert the nut 8 into the hole
By screwing them together. More specifically, the elongate member 1 is cut in advance so as to match the dimension between the girders 2, 2, and an opening formed for embedding the ceiling-embedded air conditioner 6 in the ceiling finishing material 9. 10, the long member 1 is inserted, and both ends of the long member 1 in the length direction are placed on the lower end flanges 3 of the beam members 2. The elongate member 1 is provided with a claw piece 12 having an opening at a lower end along a length direction and bent inward at an acute angle at a lower end of the left and right side plate portions 11 in a side shape. It is positioned at two appropriate positions in the length direction of the long member 1 and placed on the claw pieces 12 on both sides,
The upper end of each threaded rod 5 is screwed into each nut member 4. At this time, the upper end of each threaded rod 5 strongly contacts the inner surface of the plate portion 13 at the upper end of the elongated member 1, and the entire threaded rod 5 is tightened until each nut member 4 strongly contacts the claw piece 12. As a result, the full threaded rod 5 is connected to the elongated member 1, and the lower end of the four full threaded rods 5 suspends and supports the ceiling-mounted air conditioner 6.

[0003]

However, in the above-described structure for suspending and supporting the conventional ceiling-mounted air conditioner, the long member 1 is cut in advance so as to match the dimension between the beam members 2. It is necessary to insert the elongated member 1 through an opening 10 formed in the ceiling finishing material 9 so that both ends in the longitudinal direction of the elongated member 1 are placed on the lower end flanges 3 of the girder members 2. There was a problem that the work of placing was troublesome. The reason for this is that the length of the elongated member 1 is longer than the length between the distal ends of the lower end flanges 3 and 3 of the girder members 2 and 2, and both ends in the length direction of the elongate member 1 are connected to the lower end flanges of the girder members 2 and 2. 3,3
In order to place the elongate member 1 on the upper side, the work must be performed while the oblong member 1 is inserted obliquely from the opening 10. There is a problem that the work of placing both ends in the longitudinal direction of the member 1 on the lower end flanges 3 and 3 of the beam members 2 and 2 is extremely troublesome.

The present invention solves such a problem, and easily suspends a ceiling-mounted air conditioner, a ceiling-mounted lighting fixture, a ceiling-mounted duct, and the like to a girder above a ceiling finishing material. It is an object of the present invention to provide a suspending device such as a ceiling-mounted air conditioner for supporting.

[0005]

A sliding member, a nut member fixedly welded to a side portion of the sliding member so that a female screw hole faces up and down, and a lower end of a rod-shaped body whose upper end is screwed into the female screw hole of the nut member. Is connected to a suspended body such as a ceiling-mounted air conditioner, and the suspended body is suspended. Further, according to the present invention, the elongate member is fixed to a required length by tightening a tightening screw which is screwed into a female screw hole provided near one end of one of the cylindrical members which is the entrance side of the other cylindrical member. The gist of the above is as follows. Further, the present invention provides that the installation plate is attached to the lower surface at the other end of the one cylindrical member and the other end opposite to the one end of the other cylindrical member which is the entrance / exit side to the one cylindrical member. It is an abstract. Further, the present invention is characterized in that a through hole is formed in a plate portion forming an upper surface at the other end of one cylindrical member and the other end of the other cylindrical member.

With this configuration, the elongated member supported by the girder above the ceiling finishing material can be positioned between the supporting members such as the girder in a state where the length is reduced in advance. The long members can be easily supported on the girder etc. compared to the conventional example. As a result, the ceiling-mounted air conditioner, the ceiling-mounted lighting equipment, the ceiling-mounted ducts, etc. can be used for the girder above the ceiling finishing material. Can be easily suspended and supported.
