Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for hanging and supporting a pipe or wiring work.

[0002]

2. Description of the Related Art In a building air conditioner, for example, a large number of outdoor units are installed on a roof, and refrigerant pipes are connected between indoor units on each floor and corresponding outdoor units on the roof.

[0003] In the piping work of the refrigerant pipes, refrigerant pipes and the like from the indoor units on each floor are joined together in a pipe duct penetrating the building in the height direction, and the pipes are piped to the roof. As shown in FIG. 10, a large number of refrigerant pipes 6, 6,... Are collectively piped along a refrigerant pipe rack 1 provided on the rooftop. The refrigerant pipe rack 1 connects the lower parts of the two parallel parent girders 2 and 2 with a plurality of child girders 3 at predetermined intervals, and a roof cover 4 for protecting from rain, dust and sunlight.
2 are fixed to the upper part, and are supported by portal-type racks 5, 5,..., And the refrigerant pipes 6, 6,.

A number of outdoor units 10, 10,... Are installed along the refrigerant pipe rack 1, and the refrigerant pipes 6, 10,.
6,... Are pulled out and connected.

Conventionally, a pipe 2 from the refrigerant pipe rack 1 to the outdoor unit 10 is formed by drilling a hole 2a in the parent girder 2 of the refrigerant pipe rack 1, bending the refrigerant pipe 6 out of the hole 2a, and drawing it out. The support up to the outdoor unit 10 is supported by the support 11, and a U-shaped duct 12 for protecting from rain, dust and sunlight is placed on the refrigerant pipe 6 and supported by the support 11. Since the support base 11 is placed on the rooftop floor and is not anchor-supported because of the waterproof structure on the roof, the end 12a of the U-shaped duct is inserted into the hole of the main girder 2 of the refrigerant pipe rack 1. The frame 12a was fixed to the edge of the frame 2a by a fixing frame 13 to prevent the duct 12 and the support base 11 from shaking or falling due to strong wind or the like. (Note that in FIG. 10, reference numeral 14 denotes a laying plate supported by the support base 11.)

[0006]

However, as described above, the parent girder 2 is perforated for each of the outdoor units 10, 10,...
The operation of fixing the end 12a of the duct 12 with the fixing frame 13 is extremely complicated and time-consuming.

For this reason, this drilling process is stopped, and the refrigerant pipe 6 is bent down to the lower side of the child beam 3 of the refrigerant pipe rack 1,
If the main girder 2 is bent horizontally and pulled out from below the main girder 2 and connected to the outdoor unit 10, complicated work such as drilling of the main girder 2 becomes unnecessary.

However, when the refrigerant pipe 6 is drawn laterally from below the main girder 2 as described above, the end 12a of the duct 12 covering the refrigerant pipe 6 is not fixed to the refrigerant pipe rack 1 and is in a free state. In addition, since the support base 11 supporting the refrigerant pipe 6 is not anchored due to the waterproof structure on the roof, the duct 12 and the support base 11 swing when receiving a strong wind on the roof, and the refrigerant pipe 6 or Duct 12, support 1
1 may be damaged.

For this reason, it is necessary to suspend the end of the duct 12 from the parent girder 2 of the refrigerant pipe rack 1 to prevent the duct 12 from shaking due to strong wind or the like. SUMMARY OF THE INVENTION An object of the present invention is to provide a hanging support capable of hanging and supporting a supported body simply and reliably.

[0010]

In order to achieve the above object, a hanging support of the present invention has insertion holes at both ends, an upper bracket suspended from above and supported by both ends of the upper bracket. A bending fitting which is inserted into the insertion hole and can be bent at both ends, comprising a receiving bracket for receiving the supported body from below, and a state where the supported body is received by the receiving bracket from below. Then, the bending and locking portions at both ends of the receiving metal fitting are inserted into the insertion holes at both ends of the hanging body suspended and supported from above, and locked by bending. The supported member can be reliably suspended and supported only by an extremely simple operation of inserting and bending the bending engagement portions at both ends of the receiving metal fitting through the insertion holes at both ends of the upper metal fitting.
