Abstract

(57) [Summary] [Purpose] The present invention relates to an eaves ventilation panel that has been improved for easy installation on the eaves ceiling surface. [Structure] A synthetic resin eaves ventilation hole panel in which a mounting frame is provided around a panel having ventilation holes through which air flows on the front surface side and the back surface side, and a mounting screw formed in the mounting frame. An eaves ventilation hole panel with a structure that has an axial protrusion on the inside diameter of the hole.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an eaves ventilation panel that is easy to install on the eaves ceiling surface in an eaves ventilation panel that is attached to ventilation holes formed in the eaves ceiling for the purpose of ventilation inside and outside the eaves of a building.

[0002]

[Prior art]

 Conventional eaves-ventilation hole panels are of a type that a mounting frame is provided around a panel having ventilation holes, and is attached to the eaves ceiling surface through a mounting screw hole formed in the mounting frame. Is.

[0003]

[Problems to be solved by the device]

 However, in order to attach such an eaves ventilation panel to the eaves ceiling face up, press the eaves ventilation panel in place with one hand while using the other hand to install a screw hole. The screw must be screwed with a screwdriver while inserting the screw into the screw, and in such a work, there is a high possibility that the screw will come out of the screw hole and fall by the time the screwdriver is screwed in, and workability is poor. In view of such drawbacks, the present invention is to improve the eaves ventilation panel so that it can be easily attached.

[0004]

[Means for Solving the Problems]

 The present invention relates to a synthetic resin eaves ventilation hole panel in which a mounting frame is provided around a panel having ventilation holes on the front surface side and the back surface side. Provided is an eaves ventilation panel having a structure in which an axial protrusion is provided on the inner diameter of the screw hole.

【Example】

 An embodiment of the present invention will be described in detail with reference to the drawings. The eaves ventilation hole panel 1 is integrally formed by injection molding of synthetic resin, and a plurality of grooves 2 are formed in a rectangular panel. The front plate 3 and the back plate 4 are arranged in different steps, a large number of ventilation holes 5 are opened on the side surface of the groove 2 through connecting pieces 6, and a mounting frame 7 is provided around the rectangular panel. A screw hole 8 for attachment is formed at a predetermined position of the frame 7.

The screw holes 8 are formed with four protrusions 9 on the inner diameter in the axial direction at 90-degree intervals at four positions. The protrusion 9 can be easily integrally formed of synthetic resin when the main body of the eaves ventilation hole panel 1 is molded, and the size and the number thereof can be appropriately designed.

In order to mount the eaves ventilation panel 1 toward the ventilation hole formed in the eaves ceiling, first insert the screw 10 with the tip end thereof toward the screw hole 8 and rotate the screw 10 a little. The screw thread at the tip bites into the tip of the protrusion 9, and the screw 10 is temporarily fixed in the screw hole 8. At this time, the bite force of the screw thread at the tip of the screw 10 into the protrusion 9 is not so strong, and the size of the protrusion 9 is adjusted so that it can be easily rotated with a fingertip.

In this state, even if the eaves ventilation hole panel 1 is turned upside down, the screw 10 does not come out of the screw hole 8. Therefore, there is no risk of the screw 10 falling even if the eaves ventilation panel 1 is pressed toward the ventilation hole formed on the roof of the eaves, and the screw 10 can be easily screwed with one hand using a screwdriver. Installation on the ceiling is extremely easy.

[0009]

[Effect of device]

 As described above, according to the eaves ventilation hole panel of the present invention, the tip of the mounting screw is bite into the screw hole and temporarily fixed, so that the screw is screwed in when the mounting work is performed in the upright direction. Has the advantage of being easy.
