Description

TECHNICAL FIELD OF THE INVENTION The present invention relates to a window structure in a building, and more particularly, to improvement of a window frame mounting structure.

Technical background of the invention and its problems When building windows in a building such as a house, recently, in order to improve workability, a window frame to which a glass door or the like is preliminarily integrally attached is used. The windows can be easily constructed by nailing them to the mounting wood. Moreover, in order to facilitate the mounting of the window frame, the size of the window frame mounting wood is made wider than that of the window frame.

However, for this reason, in the conventional window structure, a gap is formed between the upper end or side end of the window frame and the window frame mounting wood, and a heat insulating defect is generated at this portion, and the airtightness is impaired. It has the inconvenience.

In order to eliminate such inconvenience, conventionally, hard foamed urethane is injected into such a gap portion by field construction. However, in the case of a window structure in which hard foam urethane is injected by on-site construction,
It is difficult to control the temperature of the rigid urethane foam, and the foaming pressure becomes uneven so that the gap cannot be sufficiently filled, or if it is injected too much, it will protrude from the gap and impair the appearance of the window.

It is also possible to pack glass wool or the like in such a gap portion, but the glass wool sticks into the hand of the operator and the construction is complicated, and if the glass wool absorbs water due to rain pits or the like, the adjacent wood will rot. Or
It has a disadvantage that it may cause mold.

The purpose of the present invention is to eliminate the disadvantages of the prior art, and while the window frame is easy to install, there is almost no gap between the window frame and the window frame mounting wood. It is an object of the present invention to remarkably improve the heat insulating property or airtightness of this portion and to provide a window structure having excellent durability.

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a window frame mounting lumber and a window frame between a window frame mounting lumber formed so as to surround a window frame to be mounted. It is characterized by interposing a soft foam plastic material having closed cells over the entire area on the surface facing the frame and having a thickness of the lower side smaller than the thicknesses of the other three sides.

According to the structure of the window according to the present invention, the soft foam plastic material is pre-attached around the window frame in a factory or the like,
Or, if this is attached to the window frame mounting wood by on-site construction and the window frame is mounted on the window frame mounting wood, the soft foamed plastic material will provide a good seal between the wooden frame and the window frame. , The installation work of the window frame is completed easily. For this reason, the airtightness in the peripheral portion of the window frame is significantly improved. In addition, since the soft foam plastic material having closed cells has excellent heat insulating property, the heat insulating property around the window frame is also significantly improved. Furthermore, since the soft foam plastic material having closed cells has good water resistance, it does not absorb moisture, does not rot adjacent wood, and improves the durability around the window.

In addition, the present invention forms a protruding portion on the outer periphery of the window frame, which protrudes outward and comes into contact with the front surface of the window frame mounting wood and is nailed, and the protruding portion and the window frame mounting wood. It is also possible to interpose a soft foam plastic material having closed cells between and.

According to the structure of the window according to the present invention, even the space between the protruding portion for nailing the window frame to the window frame mounting wood and the window frame mounting wood can be well sealed. , The airtightness is further improved.

Detailed Description of the Invention Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

FIG. 1 is a sectional view of an essential part of a window structure according to an embodiment of the present invention.

The illustrated embodiment shows an example of a window structure in a wooden house, and a window frame 6 in which a screen door 2 and sliding doors 4 and 5 made of glass doors and the like are unitized is a lintel 8 as a window frame mounting wood.
And the case where it is attached to the structural plywood 10.

In this embodiment, the structural plywood 10 is stretched on the wall of the building,
A heat insulating material 14 is arranged between the structural plywood 10 and the pillar 12. A siding material 16 is arranged on the outdoor side of the pillar 12.

The window frame 6 according to the present embodiment is attached to the window frame body 18 that holds the sliding doors 4 and 5 and the screen door 2 and the outer periphery of the window frame body 18, and is nailed to the structural plywood 10 and the lintel 8. And a window frame auxiliary body 20 having a protruding portion 22 of.

The lintel 8 as wood for mounting the window frame extends along the entire shape of the window frame 6 and has an inner peripheral dimension slightly wider than the outer periphery of the window frame main body 18 to facilitate the mounting of the window frame 6. Has been.

In particular, in this embodiment, the first airtight sheet 24 made of a soft foam plastic material having closed cells is interposed between the upper end or the side end of the window frame body 19 and the lintel 8.
The first airtight sheet 24 preferably has a thicker wall thickness in a normal state than the gap between the window frame body 18 and the lintel 8. This is because the gap is satisfactorily sealed by being interposed between the window frame main body 18 and the lintel 8 and being compressed. The thickness of the foam, which is an airtight sheet, may be determined based on its easiness of compression.

Further, between the lower end of the window frame main body 18 and the lintel 8, a second airtight sheet 25 made of a soft foam plastic material having closed cells is interposed like the first airtight sheet 24. This second airtight sheet 25 is interposed. The second airtight sheet 25 is preferably thin in view of stable accommodation of the window frame, and for example, a sheet of about 1 mm is preferably used. This is because the weight of the window frame 6 including the sliding doors 4 and 5 acts on the second airtight sheet 25, and if the sheet 25 is too thick, the attachment becomes unstable.

Further, in the present embodiment, the third airtight sheet 26 is provided between the projecting portion 22 formed on the window frame auxiliary body 20 and the structural plywood 10.
And the protruding portion 22 is nailed to the structural plywood 10 in this state. Third airtight sheet 26
Like the first and second airtight sheets 24 and 25, it is made of a soft foam plastic material having closed cells.
The thickness is preferably about 1 mm. If it is too thick, the nailing of the protruding portion 22 may be insufficient.

These first, second and third airtight sheets 24, 25, 26 are made of a soft foam plastic material having closed cells, so that not only excellent airtightness but also excellent heat insulation and water resistance are provided. Have However, the second and third hermetic sheets 25,26
In that case, since the wall thickness is thin, a high degree of heat insulation cannot be expected. However, these second and third airtight sheets 2
Since there is almost no gap in the portion where the 5,26 are mounted, heat insulation is not so required, and there is no problem because airtightness and water resistance are sufficient.

The soft foamed plastic material having the closed cells that constitutes the first, second and third airtight sheets 24, 25 and 26 is as follows.
Polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP) and the like are exemplified, and among them, PVC and the like, which are excellent in economic efficiency, are preferably used.

Such first, second and third airtight sheets 24, 25 and 26 are the second
As shown in the figure, it is preferable to stick it on the outer periphery of the window frame 6 at the factory before shipping, but it should be stuck on the spot on the lintel 8 and the structural plywood 10 as the wood for mounting the window frame. May be. As a means for sticking, a means using an adhesive, a means using these sheets 24, 25, 26 themselves as a sticking sheet, or the like can be adopted.

According to the structure of the window according to the present embodiment, the first and second airtight sheets 24 and 25 made of the soft foam plastic material are pre-attached around the window frame body 18 in a factory or the like, Alternatively, if this is attached to the lintel 8 as the window frame mounting wood by site construction and the window frame 6 is attached to the lintel 8 as the window frame mounting wood and the structural plywood 10, the soft foam plastic With the first and second airtight sheets 24 and 25 made of material sealing the wood and the window frame 6 in a good condition, the window frame mounting operation is easily completed. Therefore, the airtightness around the window frame 6 is significantly improved. Further, since the airtight sheets 24 and 25 made of the soft foamed plastic material having the closed cells have excellent heat insulating property, the heat insulating property around the window frame 6 is remarkably improved. Furthermore, since the airtight sheets 24 and 25 made of soft foamed plastic material having closed cells have good water resistance, they do not absorb moisture and do not spoil the adjacent wood. The durability of the surrounding area is also improved.

Moreover, according to the structure of the window according to the present embodiment,
Since the third airtight sheet 26 also provides good sealing up to the space between the protruding portion 22 for nailing the window frame 6 to the structural plywood 10 as the window frame mounting wood and the structural plywood 10. , The airtightness is further improved.

It should be noted that the present invention is not limited to the above-described embodiments, but can be variously modified within the scope of the present invention.

For example, the window frame 6 is not limited to the shape shown in FIG. 1, but other commonly used window frames may be used. The doors attached to the window frame are not limited to the sliding doors 4 and 5, and may be open doors. Further, the present invention can be applied not only to wooden buildings but also to other buildings. However, the present invention is applied to a building in which the window frame mounting portion is made of wood.

Effects of the Invention As described above, according to the present invention, the window frame can be easily and stably attached to the inside of the window frame mounting wood, and moreover, the window frame can be mounted between the window frame and the window frame mounting wood. It is possible to prevent the formation of gaps and significantly improve the heat insulating property or airtightness of this portion. Further, since the water is not absorbed in such a gap portion, the durability of the window is also improved.

Further, even the space between the projecting portion for nailing the window frame to the window frame mounting wood and the window frame mounting wood can be well sealed with the soft foam plastic material to further improve the airtightness. .
