Description

  The present invention relates to a structure for attaching an air-conditioning ventilation duct to the back of a ceiling.

  Conventionally, in the ceiling structure, as shown in FIG. 11, the ceiling finishing material 5 is fixed to the field edge 4, and the field edge 4 hangs on the field edge receiver 3. A suspension member 2 is hung on the field edge receiver 3, and the suspension member 2 is fixed to the ceiling slab 1.

The air conditioning ventilation duct 6 is fixed to a duct receiver 7, and the duct receiver 7 is supported by being suspended from the ceiling slab 1.

Therefore, the air-conditioning ventilation duct 6 and the ceiling finishing material 5 are individually suspended from the ceiling slab 1.

As described above, in the structure in which the ceiling finishing material is suspended, the suspension member is swung by vibration such as an earthquake, and the ceiling finishing materials, the ceiling finishing material and the wall surface, or the outlet of the air conditioning ventilation duct and the ceiling finishing material are used. May collide and fall.

For this reason, in addition to the suspension member, a seismic reinforcement member is attached to the field receiver to prevent the suspension member from swinging (Patent Document 1).

In order to avoid the concentration of seismic stress and the like, it is necessary that the seismic reinforcement member be arranged evenly with respect to the average load of the ceiling finishing material.

In addition, the air-conditioning ventilation duct is required to be arranged so that fresh air is uniformly supplied to the living space from the outlet.

Therefore, the arrangement plan of the air-conditioning ventilation duct and the seismic reinforcement member is equally arranged with respect to the ceiling finishing material, but the arrangement plan of the air-conditioning ventilation duct cannot be applied by avoiding the suspension members as in the prior art.

JP 2009-267737 A.

There are the following problems in installing the air-conditioning ventilation duct in the ceiling space to which the seismic reinforcement member as described above is attached.
<1>
In addition to the suspension support for the ceiling finishing material, it is necessary to attach a suspension member for the air conditioning ventilation duct.
<2>
The work of hanging the ceiling finishing material and the work of installing the air conditioning ventilation duct are performed separately. In many cases, the workers are different, and adjustment of each other's work is necessary.
<3> Since the seismic reinforcement member is attached to the ceiling finishing material in addition to the suspension support material, the space for arranging the air conditioning ventilation duct is narrowed.

The mounting structure of the air-conditioning ventilation duct of the present invention that solves the above-described problems is such that the outer surface of the air-conditioning ventilation duct is attached to the side surface of the seismic reinforcing member having one end fixed to the field receiver and the other end fixed to the ceiling slab. It is the attachment structure of the air-conditioning ventilation duct characterized by doing.
Moreover, the said earthquake-proof reinforcement member and the said air-conditioning ventilation duct are fixed with a sticking member.
The air conditioning ventilation duct is made of cardboard.

Since the air-conditioning ventilation duct mounting structure of the present invention is as described above, the following effects can be obtained.
<1>
Since the air-conditioning ventilation duct is attached to the seismic reinforcement member, the air-conditioning ventilation duct can be installed simultaneously with the installation of the ceiling finishing material.
<2>
Since the same worker installs the ceiling finishing material and the air-conditioning ventilation duct, work adjustment is unnecessary, so that cost reduction can be achieved.
<3>
Since the air-conditioning ventilation duct is arranged in a space region surrounded by the earthquake-resistant reinforcing member and the suspension member of the ceiling finishing material, the air-conditioning ventilation duct can be arranged without considering the arrangement position of the suspension member of the ceiling finishing material and the earthquake-proof reinforcement member.
<4>
By using a lightweight air-conditioning ventilation duct, there is no load burden on the seismic reinforcement member, and the earthquake resistance is not affected.

  Hereinafter, preferred embodiments of an air-conditioning ventilation duct mounting structure according to the present invention will be described in detail with reference to the drawings.

<1> Overall configuration.
The mounting structure of the air-conditioning ventilation duct 6 of the present invention is a structure in which the air-conditioning ventilation duct 6 is adhered and fixed to the seismic reinforcing member 8.

<2> Hanging ceiling finishing materials.
Attach a field edge to the ceiling finishing material and hang a field edge on the edge.
The suspension member fixed to the floor slab and suspended is fixed to the field receiver.

<3> Installation of the seismic reinforcement member 8.
The seismic reinforcement member 8 is attached in two directions (for example, a direction orthogonal to the field receiving direction and a direction orthogonal to the field receiving direction, or a direction orthogonal to each other by being rotated by 45 ° with respect to the field receiving direction).

  One end of the seismic reinforcement member 8 is fixed to the field receiver 3, and the other end is attached obliquely upward to the ceiling slab 1, and the seismic reinforcement member is fixed in a substantially V shape or an inverted C shape in one direction.

  When the seismic reinforcement member 8 cannot be directly fixed to the field receiver 3 depending on the mounting direction, the field receiver 3 is provided with the field receiver 3 and the seismic reinforcement member 8 is fixed to the field receiver 31. May be.

  Further, the seismic reinforcing member 8 is for suppressing the vibration of the field receiver 3 and is preferably a square steel pipe, angle steel or groove steel having a strength higher than that of the field receiver 3.

  Since the air conditioning ventilation duct 6 is attached to the seismic reinforcement member 8, a duct made of a material that does not place a load on the seismic reinforcement member 8 is preferable, and a corrugated duct is most suitable.

  In addition, it is assumed that the lightweight cardboard air-conditioning ventilation duct 6 vibrates slightly due to the airflow in the duct by using the hook-and-loop fastener. However, since the hook-and-loop fastener has vibration-proof properties, it is transmitted to the seismic reinforcement member 8. There is also an effect of preventing vibration of the ceiling finishing material 1.
