Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a structure of a sleeve portion of a door frame, such as a wooden door frame for an entrance, which improves the corrosion resistance of the lower end of the door frame.

[Background technology] The structure of the lower part of a conventional door frame is shown in Fig. 11 and Fig. 1.
Shown in Figure 2. In the sleeve portion 9 of the door frame, the vertical frame 1
A wooden lower stile 4 is installed between the lower end of the door 7 and the lower end of the mullion 3, and the lower end of this lower stile 4 is buried in the mortar floor 6. At the opening 23 of the door 7, the mortar floor 6 A stepped portion 8 was provided at the top. However, in the sleeve part 9, the lower end of the constructed upper and lower stile 4 is embedded in the mortar floor 6, so if water flows onto the floor of the entrance, the lower end of the upper and lower stile 4 can be directly removed. When the lower end of the lower frame 4 gets wet with water for a long period of time, the wooden lower frame 4 corrodes, and the painted surface of the lower frame 4 becomes discolored and deteriorates due to the alkaline components contained in the mortar.

In addition, as another conventional example, for example,
Publication No. 119082 and Japanese Utility Model Application No. 57-146682 disclose that a wooden frame material is provided between one vertical frame and the mullion of a sliding door, and a metal end cap is constructed on the bottom surface of the frame material. In addition, a rail stand is provided between the lower ends of the other vertical frame and the mullion.
However, in the above conventional example, if the rail stand and end cap were buried in the floor, the upper edges of the rail stand and end cap would be at almost the same height as the floor, When water flows into
The wooden frame material at the same height as the floor surface gets wet with water, making it impossible to waterproof the frame material, and causing problems such as corrosion and discoloration of the wooden lower stile. on the other hand,
If the upper edge of the end cap is buried above the floor surface, the upper edge of the rail base will protrude above the floor surface, and as a result, waterproofing of the lower stile and removal of the rail base from the floor surface will result. There is a problem that it is not possible to simultaneously satisfy both of the requirements for preventing protrusion.
Furthermore, conventional end caps are largely exposed to the outside, and this poses a problem in that the installation of the end caps interferes with the appearance of the sliding door.

[Purpose of the invention] The present invention has been developed in view of the above points, and is made by attaching a hakama made of metal such as stainless steel with excellent corrosion resistance to the underside of the wooden lower stile. Not only can it prevent corrosion by preventing it from getting wet directly with water, but it can also prevent the bottom frame from protruding above the floor, and it also creates a sense of unity between the bottom frame and the metal hakama. It is an object of the present invention to provide a structure of a sleeve part of a door frame that can prevent the door frame from being largely exposed toward the outdoors.

[Disclosure of the invention] That is, the structure of the sleeve portion of the door frame 10 according to the invention is such that a wooden upper frame is constructed between the upper end portions of a pair of wooden vertical frames 1, 1, and a wooden upper frame is constructed between the vertical frames 1, 1. A wing wall 12 is attached to the part surrounded by one vertical frame 1, the upper frame 2, and the mullion 3 of a door frame 10 formed by hanging a wooden mullion 3 downward from the lower surface of the upper frame 2. At the same time, a wooden lower stile 4 is constructed between the lower ends of the one vertical frame 1 and the mullion 3, and a metal hakama 5 with excellent corrosion resistance is attached to the lower surface of the lower stile 4. vertical frame 1
A lower frame 11 is constructed between the lower ends of the mullion 3 and the upper edge 1 of the hakama 5, which supports the lower surface of the lower frame 4.
8 is set higher than the upper edge 27 of the lower frame 11, and the lower part of the hakama 5 and the lower part of the lower frame 11 are placed on the floor 6.
At the same time, a protrusion 17 is provided hanging downwardly on the outdoor side A of the lower stile 4, and a recessed step 50 for accommodating the protrusion 17 is provided on the upper edge of the outdoor side A of the hakama 5. By burying the lower frame 11 in the floor 6 so that the upper edge 27 of the lower frame 11 is almost flush with the floor 6, the upper edge 18 of the hakama 5 is raised above the floor 6. It can be floated, prevents the lower stile 4 from getting wet even if water flows on the floor 6, prevents the lower frame 11 from protruding upward from the floor 6, and can be attached to the lower surface of the lower stile 4. The above object is achieved by preventing the metal hakama 5 from being largely exposed toward the outdoor side A.

[Example] The present invention will be described in detail below based on the illustrated example. As shown in FIGS. 1 and 2, a door frame 10
It is constructed by framing a pair of wooden vertical frames 1, 1, an upper frame 2, and a lower frame 11 made of stainless steel. A mullion 3 is hung downward from the bottom surface of the upper frame 2 between the vertical frames 1 and 1, and the lower end of the mullion 3 and one of the vertical frames 1
A lower stile 4 is installed between the lower end portions of the . A wing wall 12 (see FIGS. 7 to 9) is provided between the vertical frame 1, the mullion 3, the upper frame 2, and the lower stile 4. An L crosspiece 13 and a hakama 5 are attached to the lower surface of the lower frame 4. As shown in FIG. 3, a recess 14 is formed on the lower surface of the lower stile 4 over the entire length, and has a cross section of approximately L.
A fitting protrusion 15 is provided on the upper part of the L crosspiece 13 formed in the mold.
is formed, and with the fitting protrusion 15 fitted and inserted into the recess 14 of the lower stile 4, the L crosspiece 13 is fixed with a fixing tool 16 such as a wood screw. Further, the lower surface of the L crosspiece 13 is set flush with the indoor lower surface of the lower stile 4, and the lower surface of the L crosspiece 13 on the outdoor side has a protrusion 1.
7 protrudes downward over the entire length. The hakama 5 is formed by bending a metal plate with excellent corrosion resistance such as stainless steel, and has a long piece 19 hanging downward from the indoor end of the protruding piece 18, and a short piece 20 from the outdoor end of the protruding piece 18. is hung downward, and a horizontal piece 20 extends from the lower end of the short piece 20 to the outdoor side A, and as shown in FIG. 2, the horizontal piece 21 and the short piece 20 form an L-shaped cross section. A recessed step portion 50 is formed. Since the protrusion 17 of the lower stile 4 is accommodated in the recessed step 50 provided on the upper edge of the outdoor side A of the hakama 5, the metal hakama 5 is largely exposed toward the outdoor side A. is prevented. Further, a front piece 22 is formed to hang downward from the tip of the horizontal piece 20. When constructing this hakama 5, as shown in FIGS. 2 to 4, the projecting piece 18 of the hakama 5 is
3 and the lower surface of the lower stile 4, and L
With the lower surface of the protrusion 17 of the crosspiece 13 in contact with the upper surface of the horizontal piece 21, a fastener 16 such as a wood screw is screwed into the lower side of the protrusion 18 of the hakama 5 to secure the hakama 5 to the lower frame 4. Then, the lower ends of the long piece 19 and the front piece 22 of the hakama 5 are buried in the floor surface 6 finished with mortar, tiles, or the like. Therefore, protrusion 1 of hakama 5
The upper surface of the lower stile 8 is located above the floor surface 6 as shown in FIG. 2, and the lower surface of the lower stile 4 is not in contact with the floor surface 6.

Next, to show the structure of the opening 23 of the door 7 of the door frame 10, a lower frame 11 made of a metal plate with excellent corrosion resistance such as stainless steel is constructed between the mullion 3 and the lower end of the vertical frame 1. has been done. This lower frame 11 is formed by bending a metal plate, and as shown in FIG. 6, a rising piece 25 is bent upward from the indoor end of the lower piece 24 that slopes slightly downward toward the outdoor side. At the same time, a hanging piece 26 hangs downward from the outdoor end of the lower piece 24, and a floor piece 27 extends laterally from the upper end of the rising piece 25, and a door stop 28 is attached to the outdoor end of the floor piece 27. It is formed by folding the floor pieces 27 over each other, and a vertical piece 29 is further suspended from the indoor end of the floor piece 27. As shown in FIG. 5, lower frame mounting fittings 30 are fixed to the lower surface of both ends of the lower frame 11. As shown in FIG. When installing the lower frame 11 between the lower ends of the vertical frame 1 and the mullion 3, place the lower frame 11 between the vertical frame 1 and the mullion 3, and place the lower frame 11 under the lower frame mounting bracket 30. The doorstop member 31 is attached to the inner surface of the vertical frame 1 while aligning the end surface and the lower end surfaces of the vertical frame 1 and the mullion 3 flush with each other.
The lower frame 11 is arranged so that the front side of the door stop part 28 of the lower frame 11 is flush with the front side of the door stop part 28 of the lower frame 11. Then, the lower frame mounting fittings 30 are fixed to the side surfaces of the vertical frame 1 and the mullion 3 from the inside using fixing tools 16 such as wood screws. In addition, the vertical piece 29 and the hanging piece 2 of the lower frame 11
6 is buried and fixed in the floor surface 6 of mortar or the like. Then, attach the door stop beat 34 to the front side of the rising piece 25 of the lower frame 11 with a fastener 1 such as a wood screw.
It is fixed at 6.

Therefore, a lower stile 4 is constructed between the lower ends of the vertical frame 1 and the mullion 3 of the door frame 10, a metal hakama 5 is attached to the lower surface of the lower stile 4, and the lower part of the hakama 5 is covered with mortar, tiles, etc. By embedding them in the formed floor surface 6, the lower stile 4 and the L crosspiece 13 are not directly buried between the floor surfaces 6. That is, as shown in FIG. 2, the upper edge (projection) 18 of the hakama 5 is
1, so if the upper edge 27 of the lower frame 11 is buried so as to be almost flush with the floor 6, the upper edge of the hakama 5 18 can be constructed by floating it above the floor surface 6. Therefore, even if water flows onto the floor surface 6, the lower stile 4, which is higher than the floor surface, is prevented from getting wet, making it possible to waterproof the lower stile 4, and preventing corrosion, discoloration, etc. of the wooden lower frame 11. At the same time, it is possible to reliably prevent
The upper edge 27 of the lower frame 11 is at the same height as the floor 6, and the lower frame 11 can be prevented from protruding above the floor 6 while waterproofing the lower stile 4. Even if water flows from the entrance to the door frame 10 side, for example when the entrance is washed with water or in the case of rain, the lower stile 4 will not get wet with water. There is no need to worry about it rotting even if it is formed with. Furthermore, it is not affected by adverse effects such as discoloration due to alkaline components contained in the mortar. Also, mullion 3
By installing the lower frame 11 between the vertical frame 1 and the lower end of the vertical frame 1, the door 7 hits the door stop beat 34 attached to the front side of the rising piece 25 when the door 7 is opened or closed, making the door 7 airtight. It can be closed easily, and there is also the advantage that there is no need to finish the stepped portion 8 with mortar or the like as in the past, and workability can be improved. That is, conventionally,
At the opening 23 of the door 7, as shown in FIG. 12b, a step 8 is finished with mortar so that it runs along the lower edge of the door 7 when the door 7 is closed. By forming a door stop portion 28 on the frame 11 against which the lower end of the door 7 comes into contact, mortar finishing is not required. On the other hand, the second
As shown in the figure, the floor surface on the outdoor side A is normally constructed lower than the indoor side B, and in this invention,
A protrusion 17 is provided hanging downwardly on the outdoor side A of the lower stile 4,
By providing the recessed step part 50 (short piece 20, horizontal piece 21) for accommodating the protrusion 17 on the upper edge of the outdoor side A of the hakama 5, the metal-made hakama 5 attached to the lower surface of the lower frame 4
can be covered and hidden by a protrusion 17 hanging downward from the lower stile 4, and the metal hakama 5 can be prevented from being largely exposed toward the outdoor side A by using the lower stile 4. Moreover, by storing the protrusion 17 in the recessed step 50 of the hakama 5, a sense of unity can be obtained between the protrusion 17 and the hakama 5, and as a result, the lower frame 4 and the hakama 5 are integrated in appearance, and are made of metal. There is an advantage that the hakama 5 can be constructed without interfering with the appearance of the wing wall 12 (FIG. 7), which is mainly made of wood.

[Effects of the invention] As described above, the present invention has the following features: When installing the door frame on the floor, bury the bottom of the bottom frame in the floor so that the top edge of the bottom frame is almost flush with the floor. By simply doing this, the upper edge of the hakama can be raised above the floor. As a result, even if water flows onto the floor, the upper edge of the hakama, which is higher than the floor, will not get wet, making it possible to waterproof the lower sill, and the structure does not allow the lower sill to protrude upwards from the floor. As a result, it is possible to achieve both waterproofing of the lower frame and prevention of protrusion of the lower frame at the same time. Therefore, even if water flows into the entrance, for example, the lower stile will not get wet.
Even if the door frame has a wooden lower stile, there is no need to worry about the lower stile corroding or the painted surface of the lower stile becoming discolored or deteriorating due to alkaline components contained in mortar. Although the structure does not allow the frame to protrude from the floor, the wooden lower stile is effective in preventing corrosion of the lower stile and discoloration and deterioration of the painted surface.
It can be constructed without interfering with the appearance of the wing walls, which are mainly made of wood. Furthermore, since a protrusion is provided hanging downwardly on the outdoor side of the lower stile, and a recessed step is provided on the upper edge of the hakama on the outdoor side to accommodate the above-mentioned protrusion, the metal attached to the lower surface of the lower stile is A metal hakama can be covered up by a protruding part hanging down below the lower stile, and the lower stile can be used to prevent the metal hakama from being largely exposed toward the outdoors. Moreover, since the structure is such that the protrusion that hangs down below the lower stile is housed in the recessed step provided on the upper edge of the outdoor side of the hakama, a sense of unity between the protrusion and the hakama can be obtained. As a result, the lower stile and the hakama become integrated in appearance, and as a result, the metal hakama of the present invention can be constructed without interfering with the appearance of the outer wall, which is mainly made of wood. be. .
