BACKGROUND OF THE INVENTION
The present invention relates to a method for repairing a metal sash window in which a shoji is mounted on a metal sash frame so as to be opened and closed.
[0002]
[Prior art]
As a sash window, for example, a sliding window is known in which an indoor shoji and an outdoor shoji are attached to a sash frame that is an upper frame, a lower frame, and left and right vertical frames.
The above-mentioned sliding window is made of an aluminum extruded shape with an upper frame, a lower frame, and a vertical frame, a metal sliding window with a metal sash frame made of steel, and the upper frame, the lower frame, and the vertical frame with a heat insulating shape. A heat insulating sliding window with a heat insulating sash frame is known.
[0003]
In the above-mentioned metal sliding window, if the temperature difference between the indoor and the outdoor is large, the outdoor cool air is transmitted to the indoor side of the sash frame and condensation occurs on the indoor side of the sash frame. Even if the temperature difference between the room and the outdoor is large, the outdoor cold air is not transmitted to the indoor side of the sash frame, and no condensation occurs on the indoor side of the sash frame. Used in cold regions where the temperature difference from the outside is large.
[0004]
[Problems to be solved by the invention]
In recent years, even in a relatively warm area where the temperature difference between the room and the outside is small, the metal sliding window has been replaced with a heat insulating sliding window in order to make the living space comfortable.
Various methods have been proposed for refurbishing the above-described metal sliding window into an adiabatic sliding window.
For example, it has been proposed that a heat insulating sash frame of a heat insulating sliding window is attached to a metal sash frame of a metal sliding window to form a heat insulating sliding window.
[0005]
However, as described above, attaching the heat-insulating sash frame to the metal sash frame is a laborious operation and takes time, which adversely affects the daily life of the resident.
That is, since the above-described renovation work is generally performed while a person is living, if the renovation takes a long time, the daily life of a long-time resident is adversely affected.
In addition, it is necessary to use a heat-insulating sash frame and the above-mentioned difficult work takes time and the construction cost is high, so that the conventional repair method becomes expensive.
[0006]
The present invention has been made to solve the above-mentioned problems, and its purpose is to enable a simple operation to be performed in a short time and to renovate a metal sash window to a heat insulating sash window without using a heat insulating sash frame. It is to provide a method for repairing sash windows.
[0007]
[Means for Solving the Problems]
As a result of diligent research and experiments regarding the renovation of the above-described metal sash window to the heat insulating sash window, the present inventors found the following and reached the present invention.
A heat-insulated sash window that has been modified by attaching a heat-resistant sash frame to a conventional metal sash frame has excellent heat insulation properties, and no condensation occurs on the indoor side of the sash frame even when the temperature difference between the room and the room is large.
The heat-insulated sash window refurbished as described above naturally did not cause condensation on the indoor side of the sash frame even when the temperature difference between the room and the room was small, but it was noted that the temperature difference between the room and the room was small. However, when the heat transfer between the indoor side and the outdoor side of the heat-insulating sash frame is changed, even if it is a heat-insulating sash frame that conducts heat more easily than the conventional heat-resistant sash frame, condensation is formed on the indoor side of the sash frame. Did not occur.
[0008]
As a result of further research and experimentation in view of the foregoing, it is difficult to transfer heat to the indoor side and the outdoor side of the existing metal sash frame without attaching a heat-insulating sash frame. When the temperature difference is small, it has been found that no condensation occurs on the indoor side of the sash frame, and the present invention has been achieved.

DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of a method for repairing a metal sash window to a heat insulating sash window will be described.
1 and 2 are vertical and horizontal sectional views of a metal sash window, for example, a metal sliding window. A metal sash frame 3 of the metallic sliding window is attached to the opening 2 of the building housing 1. This metal sash frame 3 is composed of an upper frame 4, a lower frame 5, and a vertical frame 6. A bracket 7 connected to each frame is welded to an anchor 8 embedded in the building frame 1 to attach the metal sash frame 3. ing.
The inner sash 9 and the outer scabbard 10 are attached to the metal sash frame 3 to form a metal sliding window.
The inner and outer children 9 and 10 are schematically shown in FIGS.
[0018]
The upper frame 4, the lower frame 5, and the vertical frame 6 include a frame main body facing in the indoor exterior direction, a plurality of inwardly facing pieces, and a shoji holding member, and are made of a metal such as an aluminum extruded shape or steel. The shoji holding member is a member that holds the shoji in the sash frame in a closed state.
For example, the upper frame 4 has a frame main body 4a facing in the indoor exterior direction, an indoor inwardly facing piece 4b provided integrally with the frame main body 4a, and a member for holding the inner limb 9; 10 is an extruded aluminum member provided with a member for holding 10, that is, an outer rail upper rail 4 d and an outdoor inward facing piece 4 e.
The lower frame 5 includes a frame main body 5a facing toward the inside of the room, a room-side inward piece 5b provided integrally with the frame main body 5a, and members for holding the inner shoji 9, that is, an inner pouch lower rail 5c and an outer shoji 10. It is an aluminum extruded shape member provided with a member to be held, that is, an outer shroud lower rail 5d and an outdoor inward facing piece 5e.
The vertical frame 6 includes a frame main body 6a facing in the indoor outer direction, an indoor inward piece 6b provided integrally with the frame main body 6a, a member for holding a shoji, that is, an intermediate inward piece 6c, and an outdoor inward piece 6d. Aluminum extruded profile.
[0019]
A method of repairing the metal sliding window to a heat insulating sliding window will be described.
The inner impeller 9 and the outer imperial child 10 are removed, and the upper frame 4, the lower frame 5, and the vertical frame 6 are processed so that heat is hardly transmitted to the indoor side portion and the outdoor side portion. For example, the holes 11 are respectively machined in a plurality of portions spaced in the longitudinal direction in the middle of the interior and exterior direction of the frame main bodies 4a, 5a, and 6a of the respective frames. This hole 11 is a slit-like hole that is short in the indoor exterior direction and long in the longitudinal direction.
This slit-shaped hole 11 is processed by a grinder, a saver saw, a plasma cutting machine or the like.
That is, the above-described refurbishment work is often performed in a state where a person lives in the room, and it is preferable to process by a processing method that does not generate a flame or a spark.
[0020]
Thereby, the continuous area of the indoor side part and the outdoor side part of the upper frame 4, the lower frame 5, and the vertical frame 6 is reduced, and heat is not easily transmitted between the outdoor side part and the indoor side part of the metal sash frame 3. Become.
[0021]
The slit-shaped hole 11 is closed with a heat insulating material 11a. For example, a heat insulating material such as urethane resin is injected and filled, or a molded product of a heat insulating material such as resin or rubber is fitted to close the slit-shaped hole 11.
As a result, it is possible to compensate for a decrease in strength of each frame and to improve the appearance by closing the hole 11.
[0022]
Heat is transmitted to the indoor side and the outdoor side of the frame body 4a, 5a, 6a by continuously forming (that is, cutting) the slit-shaped hole 11 in the middle of the frame main body 4a, 5a, 6a in the longitudinal direction. You may make it not .
[0023]
An inner cover 12 having heat insulating properties and a surface (surface exposed to the room) that is difficult to transmit heat is attached to the indoor side portions of the upper frame 4, the lower frame 5, and the vertical frame 6.
For example, the resin cover 14 is fitted and attached to the surface of the cover 13 of an aluminum extruded shape member. A heat insulating resin such as urethane is sprayed on the back surface of the cover 13 of the extruded aluminum member, or a heat insulating material formed on the back surface is provided. The inner cover 12 is made of wood or synthetic wood.
[0024]
Finally, the inner shroud 9 and the outer shoji 10 removed as described above are attached to the metal sash frame 3.
This sliding window is difficult for heat to be transferred between the indoor side and the outdoor side of the metal sash frame 3, so that when there is a temperature difference between the indoor and the outdoor, the outdoor cold air is transferred to the indoor side of the metal sash frame 3. When the temperature difference between the room and the outside is small, condensation does not occur on the indoor side of the metal sash frame 3.
Therefore, it is suitable as a heat insulation sliding window used in a relatively warm area where the temperature difference between the room and the room is small.
[0025]
The above-mentioned existing shoji 9 and outer shoji 10 are metal shojis in which aluminum extrusions and steel ridges are assembled and glass is mounted on the inside. Since heat is easily transmitted to the outside, the inner sliding door 9 and the outer sliding door 10 can be replaced with a heat insulating door so that the heat insulating sliding window can be improved.
For example, it may be replaced with a shoji that does not easily transmit heat to the indoor side and the outdoor side such as a heat-insulating shoji using a heel made of a heat insulating shape.
[0026]
Since the above-mentioned heat insulating shoji has a larger expected dimension (dimension in the indoor exterior direction) than the metal shoji, it may not be held by the shoji holding member of the metal sash frame 3. For example, it may not be held in a closed state by being attached to each of the above-described upper rail and lower rail.
In this case, the shoji holding member is removed from the frame main body of each frame forming the metal sash frame 3 by cutting or the like, and the shoji holding member having a size and shape corresponding to the heat insulating shoji is attached to the frame main body.
[0027]
For example, as shown in FIGS. 3 and 4, the inner frame 4c, the upper frame 4d of the upper frame 4, the upper rail 4d of the outer frame, the lower rail 5c of the lower frame 5, the lower rail 5d of the outer frame, and the middle frame 6 Each piece 6c is removed by cutting with a cutter or the like.
On the frame body 4 a of the upper frame 4, an upper arm holding member 23 provided with an inner rail upper rail 21 and an outer arm upper rail 22 is attached to a mounting plate 20 with a screw or the like.
On the frame main body 5 a of the lower frame 5, a shijiji holding member 27 having an inner pouch lower rail 25 and an outer pouch lower rail 26 is attached to the mounting plate 24 with screws or the like.
A vertical shoji holding member 30 provided with an inward piece 29 on the mounting plate 28 is attached to the frame main body 6a of the vertical frame 6 with a screw or the like.
[0028]
The mounting position of the upper shoji holding member 23 in the indoor / outdoor direction and the interval between the upper inner rail 21 and the upper rail 22, the inner mounting position of the lower shoji holding member 26, the lower inner arm rail 25 and the outer shoji. The distance from the lower rail 26 and the mounting position of the longitudinal shoji holding member 30 in the indoor / outdoor direction are values corresponding to the expected dimensions of the heat insulating shoji.
[0029]
In this case, the hole 11 is formed closer to the interior of the frame body 4a, 5a, 6a than the respective shoji holding members.
By doing in this way, even if each shoji holding member is a metal such as an aluminum extruded profile or steel, the outdoor cold air is not transmitted to the indoor side portion of each frame through the shoji holding member.
[0030]
In the case described above, if the outdoor inward pieces 4e, 5e, 6d of each frame are obstructive, they are cut and removed.
Each shoji holding member has a shape having an outdoor inward piece.
[0031]
By doing in this way, the metal sash frame 3 can be fitted with a heat-insulating shoji with different expected dimensions from the metal shoji, for example, a heat-insulating shroud 9 and an external shoji 10 and held in the metal sash frame 3 in a closed state. it can.
[0032]
If each of the shoji holding members is made of metal and heat is not easily transmitted to the indoor side portion and the outdoor side portion, the heat insulating property is further improved.
For example, as shown in FIGS. 5 and 6, the mounting plate 20 for the upper shoji holding member 23, the mounting plate 24 for the lower shoji holding member 27, and the mounting plate 28 for the vertical shoji holding member 30 are connected to the indoor side member. 20a, 24a, 28a and outdoor members 20b, 24b, 28b are heat-insulated members connected by heat- insulating materials 20c, 24c, 28c .
[0033]
In this case, the holes 11 formed in the frame main bodies 4a, 5a, 6a of the respective frames of the metal sash frame 3 are the heat insulating materials 20c, 28c of the mounting plates 20, 24, 28 (that is, the indoor side portion and the outdoor side). The same position in the indoor and outdoor direction.
[0034]
Although the sliding window has been described in the above-described embodiment, the present invention can also be applied to a sash window such as a rotating window, a folding window, and an inside / outside-down window.
[0035]
【The invention's effect】
According to the first aspect of the present invention, heat is not easily transmitted to the indoor side portion and the outdoor side portion of the metal sash frame by the machined hole. Therefore, when the temperature difference between the room and the outdoor is small, the metal sash is caused by the cold air in the room. It is possible to prevent condensation on the indoor side of the frame.
Therefore, by processing a hole in the metal sash frame, it can be repaired to a heat insulating sash window, and it can be repaired in a short time, and there is no need to attach a heat insulating sash frame.
Therefore, it can be constructed in a short time with a simple work, and the metal sash window can be renovated to a heat insulating sash window without using the heat insulating sash frame.
[0036]
According to the second aspect of the present invention, since the hole processed in the metal sash frame is closed by the heat insulating material, the strength reduction of the metal sash frame due to the hole processing can be compensated, and the appearance is good without seeing the hole.
