BACKGROUND OF THE INVENTION
The present invention relates to a grill mounting part for use during construction of a ventilation system and a grill mounting method using the same.
[0002]
[Prior art]
In recent years, the airtightness of houses has progressed, and there is a need for mechanical ventilation using power from conventional natural ventilation that uses natural buoyancy and buoyancy of air due to the difference between indoor and outdoor temperatures. Has occurred.
[0003]
However, the following problems have been pointed out regarding the ventilation method of houses.
When the air conditioning for buildings currently used is used for a house, the high equipment cost and the operating cost become a problem, and it is extremely difficult to put it to practical use.
In addition, when local exhaust used in factories or the like is used as it is in a house, construction costs and operation costs are expensive, which is a major obstacle to the spread of ventilation systems.
Furthermore, there are few residential ventilation systems and ventilation components, so new developments must be made.
[0004]
Next, problems in the construction method of the ventilation system are shown below.
Since the ventilation system has just been introduced into the house, the construction work of the house and the piping work are not integrated, causing various problems.
In particular, with the ceiling and the inner wall attached, the problem is how to find the duct arranged on the back side and connect it to the grill, and how to attach the grill.
In the case of a house, when the ceiling or inner wall is pasted, the piping on the back side cannot be seen at all and cannot be touched.
Moreover, it is difficult to enter the piping space on the back side.
[0005]
For this reason, the grill insertion pipe protrudes from the plate-like building member which is a ceiling board or a wall board, the plate-like building member is lifted to a predetermined position, the position of the grill insertion pipe is accurately marked, and lowered to the floor A method of attaching a grill after drilling a bracket insertion hole in a plate-shaped building member based on the marking and attaching the plate-shaped building member is performed.
However, the work process is complicated, tends to be complicated, and is extremely inefficient.
Furthermore, construction costs and construction costs are also expensive, which is not realistic.
[0006]
In addition, as a simpler method than the above, the position of the grill insertion pipe is accurately marked in advance on a plate-like building member such as a ceiling plate or a wall plate, and after the plate-like building member is pasted, A bracket insertion hole is drilled in a building member and a grill is attached.
However, since the duct pipe 36 used for piping does not have a degree of freedom and is fixed to a column, a hook, or a beam, the tolerance for drilling the ceiling plate is only in mm.
It is also extremely difficult to accurately indicate the position of the insertion hole of the grill.
[0007]
Furthermore, there is also a problem in the strength of the gypsum board used for the plate-like building member that is a ceiling board or a wall board.
The gypsum board is generally known to be fragile, and as shown in FIG. 7, since the allowance between the plate-like building member 40 (gypsum board) and the bracket 34 can be only a few mm, the mounting of the bracket 34 Due to the shear stress generated at the time or when the grill is attached / detached, the end portion 46 of the bracket insertion hole of the plate-like building member 40 (gypsum board) in contact with the bracket 34 is easily broken and broken, making it difficult to attach the grill.
[0008]
From the above, ventilation systems are entering the home, but the development and construction methods of compact and inexpensive models and ventilation systems are still in the developing stage.
[0009]
