DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a rectangular air vent in air conditioning.

[0002]

2. Description of the Related Art A rectangular air vent in an air conditioner has a variable airfoil type called a universal type, a fixed airfoil type called a slit type, a punching type, etc., depending on the members used for the face. For example, a description will be given of a punching type. As shown in FIG.
The shutter 103 includes a shutter frame 102 that supports the shutter 01, a face 103 formed of a punching plate that forms a blowing surface, and the like.

In FIG. 1, reference numeral 104 denotes an air vent box connected to a duct 105 and suspended from a slab 106. A short pipe 107 having a short cross section is dropped on the lower surface of the air vent box 104. ing. The outer peripheries of the air vent box 104, the duct 105, and the short pipe 107 are covered with a heat insulating material 108 and are kept warm. In FIG.
09 is a ceiling base, 110 is a ceiling board provided on the indoor side surface of the ceiling base 109, and 113 is a packing.

A conventional method of mounting such a rectangular ventilation opening will be described with reference to FIG. 12 and the following drawings. First, as shown in FIG. The air vent box 104 is suspended from the slab 106 in accordance with the floor ink thus discharged, and then the air vent box 104 and the duct 105 are kept warm.

[0005] Next, as shown in FIG.
9 and the ceiling base 1
At 09, a rectangular marking indicating the opening position of the base is made, and the opening is reinforced with the opening reinforcing material 112 on the ceiling base 109 using the mark as a mark. Then, as shown in FIG. 14, the ceiling base 109 is opened according to the marking.

Next, as shown in FIG. 15, the lower surface of the air vent box 104 is opened, and the short pipe 107 having a rectangular cross section is lowered to the lower surface of the ceiling base 109. This work is performed through a gap in the base of the ceiling.

[0007] The outer periphery of the short pipe 107 and the vicinity of the connecting surface with the short pipe 107 on the lower surface of the air vent box 104 are kept warm by a heat insulating material. Then, as shown in FIG. Is attached to the ceiling board 110.

Next, a board opening size is drawn on the ceiling board 110 in accordance with the above mentioned floor ink. That is, the rectangular ink is transferred to the board surface. Thereafter, the ceiling board 110 is opened according to the opening size as shown in FIG. Thereafter, as shown in FIG. 18, the shutter 101 of the air vent is attached, and finally, the face 103 is attached as shown in FIG.

[0009]

However, such a conventional method has the following problems. First, when drawing the opening size of the rectangular ventilation opening on the board 110, the operation is difficult because the opening shape is rectangular. For example, in the present situation, first, two sets of parallel lines are drawn, and a rectangle is drawn using the intersections as the four vertices of the opening rectangle. Therefore, the parallel lines protruding outside the opening must be erased with an eraser or the like, and the board surface is often contaminated. Furthermore, since the ruler is drawn in close contact with the outside of the opening to draw parallel lines and the like, if the ruler is dirty, the board surface may still be soiled. In addition, since the work is performed with a ruler in one hand and a pencil in one hand, the work on the board is considered to be extremely difficult work in view of the upward work. Moreover, since the opening operation itself is performed by a rotary saw, the rectangular opening must be performed by dividing four sides into four times, which is troublesome.

As is apparent from the above description, in the conventional method, a step of lowering the short pipe 107 and performing a heat retaining process is interposed between the working step of the ceiling base and the attaching step of the board 110. Considering that the former two processes are construction work and the latter process is air conditioning work, such a mixture of construction work and air conditioning work many times on the way in terms of productivity and work efficiency. Not preferred.

An object of the present invention is to solve the drawbacks of the conventional mounting method, such as the complicated opening work and the low productivity.

[0012]

SUMMARY OF THE INVENTION Therefore, the present invention provides a method for attaching a rectangular ventilation opening in the following manner. That is, in the method of attaching a rectangular ventilation opening connected to the ventilation opening box to the ceiling surface, a circular ink is put out, an opening operation is performed on a ceiling base according to the ink, and a ceiling board is attached after the opening operation, The ink was transferred to the ceiling board, the ceiling board was opened, the lower surface of the air vent box was further opened, and a short pipe with a circular cross section with a shutter was attached to the lower surface of the air vent box. The outer circumference of the pipe and the vicinity of the mounting portion between the short pipe and the air vent box are kept warm, and then a cone is fixed to the short pipe, and a rectangular face is mounted on the cone.

[0013]

[Action] Inking on the floor surface according to the ceiling plan, basement of the ceiling,
Since the openings in the ceiling board are all circular, the compass can be used for inking with one hand, and there is no extra line outside the opening. Further, the opening operation with a saw can be easily performed. In addition, there is no need for air conditioning work such as installation of short pipes or heat insulation between construction work such as installation of a ceiling base and opening work of an opening to a ceiling board.
