Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to opening structures such as windows, doorways, and skylights provided in buildings.

[Conventional technology]

A window frame will be described as an example of a conventional frame used in the above-mentioned opening structure of a building. Conventionally, as a window frame, a vertical frame is fixed to both ends of an upper frame, and both ends of the lower frame are fixed to the lower ends of these vertical frames, and the upper frame and the vertical frame are connected to the peripheral wall part and the peripheral wall part. It is known that the sash bar is integrated with a flange portion projecting from the outdoor side end portion at right angles to the outer peripheral side of the frame body.

In addition, as shown in Utility Model Publication No. 176976,
There is also known a window frame in which protrusions having short protruding heights are protruded from a plurality of locations in the width direction of the flange portion on the outdoor side surface of the flange portion of the vertical frame.

There is also an opening structure in which the former conventional window frame is fitted into a peripheral wall of an opening in a building, and the flanges of the upper frame and vertical frame are covered with exterior mortar from the outdoor side, leaving the inner peripheral edges.

In addition, in the latter conventional window frame, the peripheral wall portion is fitted into the opening of the building, and at the flange portion of the vertical frame, the outdoor side surface of the protrusion is brought into contact with the frame-shaped finishing material.

[Problems to be Solved by the Invention] However, in the former structure of openings in buildings using window frames, rainwater and the like seeps into the room from the exterior material through the space between the exterior mortar and the flange. Therefore, waterproofing treatment is carried out, such as covering the joint corner of the exterior mortar and the flange with caulking material, but it is time-consuming to install, and the caulking material deteriorates due to long-term use, causing rainwater to leak out. seeps into the room from between the flange portion and the exterior mortar, causing rain leaks.

Furthermore, even in the case of the opening structure of a building using the latter window frame, rainwater seeps in between the protrusion provided on the flange of the window frame and the finishing material. Therefore, instead of using a finishing material, it may be possible to cover the flange by filling the exterior mortar between the protrusions.In this way, it is possible to considerably prevent rainwater from seeping in between the exterior mortar and the flange. , When a force is applied to at least one of the upper frame, vertical frame, and exterior mortar to separate them in the indoor/outdoor direction, a gap is likely to form between the flange portion and the exterior mortar, and rainwater etc. seeps through the gap. It was hot.

The present invention solves the above-mentioned problems, and even if a force is applied to separate the flange portions and the exterior mortar provided on the upper frame and vertical frame of a frame such as a window frame, the flange portion and the exterior mortar are not connected to each other. It is difficult for gaps to form between them, making it difficult for rainwater to enter the interior of the room from the joints between the flanges of the upper frame and vertical frame and the exterior mortar that covers them, and also to prevent rainwater from seeping into the upper corners of the frame. It is an object of the present invention to provide a building opening structure that can actually prevent openings without complicating the frame structure.

[Means for solving problems]

In the opening structure of a building according to the present invention, the upper frame and the vertical frame are integrally formed with a peripheral wall part and a flange part bent at right angles and protruding from the outdoor end of the peripheral wall part toward the outer peripheral side of the frame body, Draining ridges are formed on the flange portions of the upper frame and the vertical frame in parallel with each other at multiple locations in the width direction of the flange portions, protruding outward from the outdoor surface along the longitudinal direction thereof, and the draining ridges have tips. It is constructed of an integrally molded product with an inclination toward the periphery of the frame, and isosceles right triangular draining ridge cutouts are formed at the upper end of the flange portion of the vertical frame, and these draining ridge cutouts are Overlap the protruding ends of the isosceles right triangle provided at both ends of the flange part of the upper frame,
The upper end of the draining ridge provided on the flange of the vertical frame and both ends of the draining ridge provided on the flange of the upper frame,
These protrusions abut each other over the entire length protruding from the flange portion, fixing both ends of the upper frame and the upper end of the vertical frame, and fixing both ends of the lower frame to the lower end of the vertical frame to form a rectangular shape. The upper frame, the lower frame, and the peripheral wall of the vertical frame are fitted into the opening of the building, and the frame is fixed to the member surrounding the opening, and the flanges of the upper frame and the vertical frame are fitted into the opening of the building. All of the draining ridges installed in the building are embedded in the exterior mortar that covers the exterior side of the building's exterior wall.

[Effect]

In the opening structure of a building according to the present invention, when a force is applied to at least one of the upper frame, the vertical frame, and the exterior mortar to separate them in the indoor-outdoor direction, the plurality of draining ridges embedded in the exterior mortar are activated. Due to the slope, compressive force is applied to the exterior mortar between the draining ridge and the flange, making it difficult for gaps to form between the flange and the exterior mortar, allowing rainwater to seep in between them. can be reliably prevented. In addition, since the tips of the draining ridges provided on the flanges of the upper frame and the vertical frame have slopes toward the periphery of the frame, water such as rainwater flows from the periphery of the frame toward the outer periphery. Even if water attempts to pass between the flange portion and the exterior mortar, the slope of the draining ridges causes water to return to the periphery of the frame body, making it difficult for water to flow beyond the draining ridges to the outer periphery. moreover,
An isosceles right triangular draining ridge cutout is formed at the upper end of the flange of the vertical frame, and the isosceles right triangular protruding ends provided at both ends of the upper frame flange are overlapped with these drainer ridge cutouts. , the upper end of the draining ridge provided on the flange of the vertical frame and both ends of the draining ridge provided on the flange of the upper frame were butted together over the entire length of these ridges protruding from the flange. Water that is prevented from entering the outer periphery of the upper frame by the draining ridges on the frame bends from both ends of the draining ridges on the upper frame to the upper end of the draining ridges on the vertical frame and flows down along these draining ridges. Even if the draining ridges on the vertical frame and the upper frame are slanted, water such as rainwater will not easily leak from the butting portions to the width direction of the flange portion and to the outside of both ends of the flange portion of the upper frame. are formed at multiple locations on the flange portion, and water leakage at the upper corners of the frame can be reliably prevented. Furthermore, since the draining ridge can be integrally molded with the flange portion, the structure of the frame body is hardly complicated.
