DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, a preferred embodiment of the ventilation structure will be described with reference to the drawings. FIG. 1 is a perspective view schematically illustrating a ventilation structure, FIG. 2 is a partial cross-sectional view illustrating a configuration of a connection portion between an upper end of a lower floor and a lower end of an upper floor, and FIG. 3 is a back side of an outer wall panel. FIG. 4 is a diagram for explaining the configuration, and FIG. 4 is a diagram for explaining a ventilation passage formed when the outer wall panels are made continuous.
[0014]
Prior to the description of the ventilation structure according to the present invention, the configuration of the outer wall panel will be described with reference to FIG. In the figure, the outer wall panel 1 can selectively use a precast concrete (PC) panel or a lightweight cellular concrete (ALC) panel which is a concrete-based panel. In this embodiment, an ALC panel is used as the outer wall panel 1.
[0015]
The outer wall panel 1 has a preset dimension and is formed in a panel shape, and a design pattern is formed on the outdoor side surface as necessary. Further, a notch 3 is formed at an end portion in the left-right direction on the indoor side surface (back surface) 1 a of the outer wall panel 1.
[0016]
In particular, a chamfered portion is generally formed at the left and right ends of the outer wall panel 1, and the notch 3 is formed with a larger dimension than the chamfered portion, but a new processing step is added. There is no need to change the processing dimension in the chamfered portion forming step. For this reason, productivity is not inhibited.
[0017]
Moreover, when using when constructing the target building, it is preferable to use the same outer wall panel 1 in which the notch 3 is formed at the same position on the back surface 1a. Thus, by using the outer wall panel 1 of the same specification, It is possible to configure a ventilation passage by communicating the notch 3 in the vertical direction.
[0018]
The notch 3 formed in the outer wall panel 1 has a function of forming a ventilation passage on the back surface 1a of the outer wall panel 1, and the shape and dimensions of the notch 3 can be used as long as this function can be exhibited. It is not intended to limit. In particular, the notch 3 is configured to be able to communicate vertically with a portion corresponding to the floor connecting the lower floor and the upper floor.
[0019]
When forming the notch 3 in the process of manufacturing the outer wall panel 1, it is advantageous to form the notch 3 in the process of continuously moving the tool. . In particular, by forming the notch 3 over the entire length of the outer wall panel 1 in this manner, even when a heat insulating material or a sound absorbing material is installed along the back surface 1a of the outer wall panel 1, a passage for ventilation is reliably ensured. Is possible.
[0020]
An outer wall panel 1 arranged on the top floor (second or third floor) of the building, and a ventilation port 4 (see FIG. 1) is provided in the vicinity of the upper end of the outer wall panel 1 arranged in a preset part. The ventilation port 4 communicates the outside air with the indoor side. In a building such as a general house, sufficient ventilation can be expected by the above configuration. However, in the case of a building that requires more ventilation, it is preferable to form the ventilation opening 4 in the vicinity of the upper end portion of the outer wall panel 1 corresponding to each level. Thus, even when the ventilation ports 4 are formed for each level, the absolute number can be reduced as compared with the number of conventional ventilation ports.
[0021]
Next, the ventilation structure will be described. The upper flange 11a of the beam 11 constituting the building frame is attached with a piece-shaped support 12 that supports the lower end of the outer wall panel 1 arranged on the upper floor, and the lower flange 11b is mounted on the lower floor. A piece-like support fitting (not shown) that supports the upper end portion of the outer wall panel 1 to be arranged is attached. When there is a possibility that the receiving metal 12 is disposed at a position facing the notch 3 formed in the outer wall panel 1, it is preferable to form a ventilation hole or a notch 12a in the receiving metal 12 in advance. .
[0022]
In this embodiment, the metal fittings for attaching the outer wall panel 1 to the beam 11 do not have to be special, and may be metal fittings that are generally used. And the outer wall panel 1 arrange | positioned at each hierarchy is attached to the beam 11 with the corresponding metal fitting 12 and the support metal fitting, respectively.
[0023]
The beam 11 is provided with a mortar blocking member 13 for preventing the mortar from entering the notch 3 formed in the outer wall panel 1 attached to the beam 11, and the mortar blocking member 13 constitutes a floor. This prevents the mortar that is placed from entering the notch 3.
[0024]
That is, a plurality of floor panels 14 are laid on the upper flange 11a of the beam 11 and fixed by a predetermined means, and a mortar 15 is placed on a plane constituted by these floor panels 14 to form a floor slab. When the mortar 15 placed at this time adheres to the back surface 1a of the outer wall panel 1, the mortar 15 may enter the notches 3 and close them. However, by providing the mortar prevention member 13, the mortar is prevented from flowing out. It is possible to eliminate this fear.
[0025]
The mortar blocking member 13 may be any member that can prevent the mortar that has been placed from entering the notch 3 formed in the outer wall panel 1. Therefore, the mortar blocking member 13 may be, for example, a plate-like member attached over the entire length of the beam 11, or may be a piece-like member arranged for each notch 3.
[0026]
When the outer wall panel 1 is attached to the receiving bracket 12 of the beam 11, the mortar blocking member 13 may abut against the back surface 1a of the outer wall panel 1, and the notch 3 formed on the back surface 1a of the outer wall panel 1 and the mortar blocking member By 13, it becomes possible to secure a passage where the mortar 15 does not enter.
[0027]
In a building constructed as described above, continuous ventilation is required from the ventilation port 17 formed on the foundation 16 to the outer wall panel 1 on the first floor, the beam 11 and the ventilation port 4 formed on the outer wall panel 1 on the second floor. It is possible to ensure ventilation along the arrow b in FIG.
[0028]
Therefore, the ventilation port formed at the upper end portion of the outer wall panel 1 corresponding to the first floor, the ventilation port formed at the lower end portion of the outer wall panel 1 corresponding to the uppermost floor, and the outer wall panel 1 corresponding to the intermediate floor. It is no longer necessary to form ventilation openings formed at both upper and lower end portions, and the processing cost for the outer wall panel 1 can be reduced.
[0029]
【The invention's effect】
As described above in detail, in the ventilation structure according to the present invention, when the outer wall panel is attached to the lower floor and the upper floor by forming notches on both sides in the left-right direction on the back surface of the outer wall panel, these floors are Regardless of the floor to be configured, it is possible to configure a passage communicating in the vertical direction.
[0030]
For this reason, the passage for ventilation which was conventionally independent for every floor can be connected from a lower floor to the top floor, and the vent formed in each floor can be excluded in connection with this. Therefore, there are not many ventilation openings in the outer wall panel, and the design can be improved. Moreover, since processing for the outer wall panel can be reduced, the cost can be reduced. Furthermore, since the opening part in an outer wall can be decreased, the invasion of rain water to the indoor side can be prevented.
[0031]
Also, by providing a mortar blocking member at the connection site between the outer wall panel and the floor, the mortar placed when the upper floor is constructed does not enter the notch formed in the outer wall panel, and these notches It is possible to secure a passage for ventilation formed through the.
[0032]
In addition, when the notch formed on the back surface of the outer wall panel is formed over the entire length in the vertical direction of the outer wall panel, the top and bottom A passage for ventilation that penetrates in the direction can be secured.
