Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a ventilation port component used for forming a ventilation opening for attic ventilation in an eave ceiling of a building such as a house.

[0002]

[Problems to be solved by conventional techniques and devices]

 If an eaves ceiling is attached to the eaves, it is preferable to provide ventilation holes on the eaves ceiling for ventilation in the attic. However, eaves ceilings are the most vulnerable places to spread fire in the event of a fire in a neighboring house.Therefore, regulations on the use of fireproof materials for eaves ceiling panels and the size of ventilating vents, etc. Have various restrictions. For this reason, even though it is known that it is desirable to provide a ventilation opening on the eave ceiling, there are many cases where it is usually unnecessary to provide a ventilation opening due to the troublesome design and construction.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an eaves ceiling ventilation port component that can easily provide a ventilation port that conforms to regulations in terms of fire protection and the like. Another object of the present invention is to provide an eaves ceiling ventilation member having a simple structure and excellent workability.

[0004]

[Means for Solving the Problems]

 The technical means of the eaves ceiling ventilation component of the present invention consists of a metal surface plate and a non-combustible backing material.The ventilation holes are formed on the surface plate with the size and spacing that conform to the regulations. Therefore, the backing material is stuck to the back of the face plate except for the ventilation holes.

[0005] Furthermore, the ventilation port may be constituted by a large number of elongated holes, and each hole may be formed by a pressing process in which cuts are made on both side edges. Further, mounting feet may be continuously provided on the edge of the surface plate. The backing is preferably made of gypsum board.

[0006]

[Embodiment of the invention]

 The embodiment of the eaves ceiling ventilation opening component of the present invention will be described based on the example of the drawings. As shown in the cross-sectional view of FIG. 1, the member of the present invention is a long material having an appropriate length (1820 mm in the embodiment), a metal surface plate 1 such as stainless steel, and a gypsum board. And a backing material 2 made of non-combustible material. Both edges of the surface plate 1 extend in the rear direction to form mounting feet 3 and 4.

As shown in FIG. 2, ventilation holes 5 of an appropriate size are formed on the surface plate 1 at appropriate intervals. It should be noted that the size of the ventilation port 5 and the interval at which the ventilation port 5 is formed are related to fire protection, and thus must be carefully set in accordance with the regulations. In the embodiment, the ventilation holes 5 have a size of 194 × 49 mm, and are formed at equal intervals with an interval of 261 mm. Further, as shown in the rear view of FIG. 3 and the cross-sectional view of FIG. 1, the detailed shape of the ventilation port 5 is a shape in which a number of elongated holes 6 are arranged. It is formed by indentation processing in which a cut is made. Therefore, the air passing through the hole 6 cannot pass through at once, but once hits the pushing surface, passes through the gap formed on the side surface. For this reason, although the air permeability is slightly inferior, it is excellent in terms of fire prevention.

[0008] The backing material 2 made of gypsum board or the like is provided according to laws and regulations in order to improve fire resistance, but is not attached to the position of the ventilation port 5 as shown in FIG. , Opening 7. In the embodiment, as shown in FIG. 3, the opening 7 is not formed in one piece of the backing material 2, but the backing material 2 is divided into a plurality of pieces and the ventilation holes 5 are left. The opening 7 is formed by lining.

Next, a method of mounting the member of the present invention will be described. FIG. 4 is an example of an attachment example. In FIG. Reference numeral 10 denotes an eave ceiling plate, 11 denotes a field edge, 12 denotes a field edge receiver, 13 denotes a nose concealing base, 14 denotes a nose concealment, and 15 denotes a fitting. That is, when the eaves ceiling plate 10 is stretched, only the width of the ventilation opening component is left on a part of the ceiling surface, and the ventilation opening component is attached and fixed to the lower surface of the remaining portion. In this case, various methods such as nailing the feet 3 and 4 to each member of the building can be adopted as the fixing means. In the embodiment, a method of opening and fixing the separate mounting brackets 15 is adopted, but the fixing method is free and is not limited to the embodiment. Further, in the embodiment, the formation position of the ventilation port is provided next to the fasciae 14, that is, on the side of the eaves. However, it can be provided at the center of the eave ceiling or on the wall side. .

The present invention is not limited to the above-described embodiment, but can be freely modified and implemented within the scope of the claims of the present invention. In particular, the material of the surface plate 1, the size, shape, and forming method of the ventilation port 5, the material of the backing material 2, the backing method, and the mounting position and fixing method of the ventilation port components to the eaves ceiling are free. It is.

[0011]

[Effect of the invention]

 The ventilation port component of the present invention is a long plate that is provided with a ventilation port that conforms to the regulations in advance. This makes it very easy to form ventilation openings that meet the regulations on the eaves ceiling, which is very convenient for building design and construction. In addition, the present invention is excellent in fire resistance because the back surface of the metal surface plate is lined with a non-combustible material. In addition, the present invention has practical advantages such as simple structure, low production cost, and low cost.

According to the second aspect, the hole formed in the ventilation port is not completely penetrated, so that the flame does not enter the ceiling at once at the time of a fire, and is excellent in fire prevention.

According to the third aspect, since the foot portion is provided, it is convenient for mounting and fixing, and the efficiency at the time of construction can be improved.

According to the fourth aspect, since the backing material is made of a gypsum board, sufficient fire resistance can be obtained and the production cost is also advantageous.
