Abstract

<P>PROBLEM TO BE SOLVED: To provide an outer wall structure according to the external insulation method, which can use the same sash and accessories as those employed in the internal insulation method, and can reduce various costs for production, control, and construction. <P>SOLUTION: In the outer wall structure according to the external insulation method, a sash bearing frame 10 formed of a skeleton mounting portion mounted on a building skeleton, and a window frame mounting portion in which a sash window frame is mounted, is arranged in an outer wall opening A. A depth dimension from a skeleton outdoor surface to a peripheral outdoor-side edge of the sash bearing frame 10 is set to a value larger than a depth dimension from the skeleton outdoor surface to an outer wall surface, and at least a waterproof tape 42 is stuck to an area between an outdoor surface of a heat insulating material 5 and the sash bearing frame 10. Thus, the difference between a depth dimension from the skeleton to an outer wall material according to the internal insulation method, and the depth dimension according to the external insulation method, can be absorbed by the sash bearing frame 10, and the same window frame is available in both the internal and external insulation methods, which contributes to reduction in the type of window frame, thereby leading to reduction in production cost and control cost. <P>COPYRIGHT: (C)2003,JPO

が生じやすかった。BACKGROUND ART In recent years, heat insulation performance has been emphasized in order to form a comfortable living space and reduce energy used for heating and cooling to save energy. Here, as a heat insulating method for the outer wall portion of the building, an inner heat insulating method and an outer heat insulating method have been conventionally used.
In addition, the inner insulation method and the outer insulation method, in a narrow sense, means to insulate the heat storage body like concrete construction,
It is used by distinguishing it from the filling heat insulation (inner heat insulation) and the outer heat insulation (outer heat insulation) when there is no heat storage body such as a steel structure or a wooden structure, but in the present invention, the filling heat insulation method and the inner heat insulation method in a narrow sense are collectively referred to as the inner heat insulation method. The external insulation method and the external insulation method in a narrow sense are collectively referred to as the external insulation method. The inner insulation method is to arrange a heat insulating material between the structural frames or inside the room. Usually, a fiber type (glass wool, etc.) heat insulating material is filled between the frames (between pillars, etc.) for construction. Often. In this inner insulation method, the cost of the heat insulating material is low, so the cost of the heat insulating material can be reduced. However, the structure such as pillars becomes a heat bridge and the heat insulation performance cannot be so high, or the inside of the wall is cooled by the outside air, so that condensation occurs when indoor air (humidity) flows into this wall. There is. Therefore, a moisture-proof treatment must be performed by attaching an airtight moisture-proof film to the indoor surface of the wall so that the air in the room does not enter the wall body, and the construction cost is also high. Furthermore, since it is not possible to place heat insulation materials continuously on pillars, etc., in order to carry out construction so that there are no gaps between the heat insulation material and the structure, there is a part that depends on the skill of the builder and skill is required. It was easy for the workers to have variations in quality.

いる。Therefore, in recent years, an outer insulation method which is more excellent in heat insulation performance has been used. The outer insulation method is to arrange a heat insulating material on the outdoor side of the structural body.
In general, an external construction method in which a plastic heat insulating plate material such as foamed plastic is stretched outside the body is common. And
In the external insulation method, the entire building is covered with a heat insulating material, so the heat capacity is large and the room temperature can be stabilized,
Since there is no heat bridge and the heat insulation line is continuous, the heat insulation performance can be improved and internal condensation is less likely to occur.
Furthermore, since the heat insulating plate itself has a high moisture permeability resistance, and the air (humidity) on the indoor side hardly reaches near the outdoor surface where the temperature of the heat insulating material is low, it is possible to reduce the time and effort of the moistureproof treatment, and the durability is high. There is also an effect that airtightness is good. For this reason,
In recent years, as compared with the inner insulation method, the outer insulation method, which has excellent heat insulation performance and generates less dew condensation, is often used.

枠を用いることができる。By the way, in the external heat insulation method, the heat insulating material and the outer wall material are sequentially arranged on the outdoor side of the body, and an air layer (a ventilation layer) is usually provided between the outer wall material and the heat insulating material. ,
The thickness from the skeleton to the outer wall is larger than that of the inner insulation method. For this reason, in the case of the outer insulation method, the following sash accommodation, which is different from the case of the inner insulation method, has been adopted. A first method is to use a sash window frame having a large prospective dimension (indoor / outdoor dimension) according to the thickness dimension of the outer wall portion. That is, the end surface of the outer wall material is waterproofed by filling a backup material and a sealing material with the window frame of the sash. Therefore, it is necessary to extend the window frame to the arrangement position of the outer wall material (position in the prospective direction). The second method is to fix a connecting plate material corresponding to the thickness dimension of the heat insulating material to a building body such as a pillar with a nail or the like, and attach a sash window frame to the connecting plate material. In this case, the size from the mounting position of the window frame to the position of the outer wall material can be made the same as that of the inner heat insulating system, so that the window frame having the same expected size can be used.

ないという問題もあった。However, according to the first method, it is necessary to prepare window frames having different expected dimensions for the inner insulation method and the outer insulation method. In order to make it selectable depending on the construction area, there is a problem that a plurality of types of window frames must be manufactured and prepared, resulting in high manufacturing costs and management costs. On the other hand, in the second method, since the window frame is supported by the connecting plate member fixed to the frame body such as a pillar with nails or the like, a sufficient long-term support strength is provided especially when a double-layered glass sash having a large load is attached. There was a problem that it was difficult to verify whether it could be secured. In addition, since this connecting plate is fixed to the skeleton at the site, it takes a lot of work at the site,
There were also problems that the construction period could not be read and work costs increased. Furthermore, since the position of the window frame of the sash moves to the outside of the building by the thickness of the connecting plate, accessories such as window frames arranged on the inside are used during the internal insulation method. There is also a problem that it is necessary to prepare a connecting plate material having a larger prospective dimension by the thickness dimension of the connecting plate material.

や気密性に優れた外壁構造にできる。According to the present invention, there is provided an outer insulation type outer wall structure in which a heat insulating material is arranged on the outer side of a frame of a building, and an outer wall material is arranged on the outer side of the heat insulating material. In the opening, a sash support frame including a skeleton mounting part to be mounted on the skeleton of the building and a window frame mounting part to which the window frame of the sash is mounted, and the outer peripheral surface of the sash support frame is the sash supporting frame. The expected dimension from the outdoor surface to the outdoor edge of the outer peripheral surface of the sash support frame is set to be equal to or greater than the expected dimension from the outer surface of the skeleton chamber to the outer wall surface, and it extends across the outdoor surface of the heat insulating material and the sash support frame. At least a waterproof tape is attached. Here, the outer peripheral surface of the sash support frame is a side surface facing the heat insulating material and the outer wall material arranged around the sash support frame. That is, of the two side surfaces (inner peripheral surface and outer peripheral surface) along the indoor / outdoor direction in each frame member, this is the side surface facing the outer peripheral side of the frame. In the present invention, since the sash support frame is interposed between the window frame and the outer wall material, the end face of the outer wall material can be stored by filling the seal material between the outer wall material and the sash support frame. Therefore, even in the outer insulation method in which the estimated size from the frame to the outer wall material is larger than that in the inner insulation method, the sash support frame can absorb the difference in size, and the window frame itself can be the same in each method. Can be used,
The number of window frames can be reduced, and manufacturing costs and management costs can be reduced. Further, since the window frame is fixed to the sash support frame made of a metal material such as aluminum, the support strength can be improved compared to the case where it is supported by the conventional wooden connecting plate material, and the weight is large. Even a sash incorporating a double glazing can be stably supported for a long period of time. Further, unlike the conventional method, it is possible to save the labor of attaching the connected timber on site, predict the construction period, and reduce the work cost. In particular, when connecting timber is used, first, firmly fix the timber to the frame such as a pillar with nails, screws, adhesives, etc., and then fix the window frame to the timber with screws. In contrast to this, in the present invention, for example, after the support frame is fixed to the window frame with screws or the like in advance and integrated, the support frame can be attached to the frame such as a pillar, and the attachment work to the frame side Since it is required only once, the labor can be saved, the construction period can be shortened, and the cost can be reduced. In addition, since the waterproof tape is attached over the heat insulating material and the sash support frame, it is possible to reliably block the space between the heat insulating material and the sash support frame for waterproofing in the external heat insulation method, and to provide heat insulation and airtightness. Excellent outer wall structure.

る。Here, on the outer peripheral surface of the sash support frame, there is formed a protruding piece portion that protrudes in a direction substantially orthogonal to the outer peripheral surface, and the outer surface of the chamber is substantially flush with the outer surface of the heat insulating material.
It is preferable that the waterproof tape is attached across the outdoor surface of the heat insulating material and the outdoor surface of the protruding piece portion. If the sash support frame is provided with the protruding piece portion, the waterproof tape can be applied in a flat state, each waterproof tape can be reliably applied without a gap, and the workability on site can be improved.

The corner member of the sash support frame may be provided with a corner member that closes the gap between the waterproof tapes that are attached along the respective frames of the sash support frame while being bent and attached in a shape. In the present invention as described above, since the waterproof tape is attached over the outdoor surface of the heat insulating material and the outer peripheral surface of the sash support frame that is substantially orthogonal to the outdoor surface, the waterproof tape is bent into an L-shaped cross section. Will be done. For this reason,
At the corners (four corners) of the sash support frame, that is, at the portions where the waterproof tapes arranged along the upper and lower frames of the sash support frame and the waterproof tapes arranged along the vertical frame cross each other, the waterproof tape is Since it is bent, a part of the waterproof tape must be cut and overlapped, and a pinhole is formed at that part. However, in the present invention, since the corner member for closing the pinhole (gap) is provided, it is possible to secure the waterproof performance with the corner member without generating the pinhole in the waterproof tape,
It is possible to prevent deterioration of airtightness and waterproof performance.

It is preferable that it is attached over the outer peripheral surface of the support frame. Even when a moisture permeable waterproof sheet is attached to the outdoor surface of the heat insulating material to further improve the airtightness, it is preferable to attach the edge of the moisture permeable waterproof sheet to the sash support frame portion to prevent a gap or the like. . When sticking such a moisture-permeable waterproof sheet across the heat insulating material and the sash support frame, if the protruding piece portion is provided, the moisture-permeable waterproof sheet should be attached in a flat state like a waterproof tape. The tapes and sheets can be securely attached without any gaps, and the workability on site can be improved. Further, when the moisture-permeable waterproof sheet is attached across the heat insulating material and the sash support frame by bending it in an L shape like the waterproof tape and attaching the same, a corner member is provided to provide the sash support frame. No pinholes are formed at the corners, and the gap can be reliably closed.

壁構造と同じ作用効果を奏することができる。The sash support frame of the present invention is substantially the same as the skeleton attachment portion attached to the skeleton of the building, the window frame attachment portion to which the window frame of the sash is attached, and the outdoor surface of the heat insulating material disposed outside the skeleton. It is characterized in that it is provided with a protruding piece portion having an outdoor surface that is flush with one another, and a decorative surface portion exposed to the outside of the room. Here, the estimated size from the frame mounting portion to the outdoor end of the sash support frame is usually set to be equal to or larger than the estimated size from the frame chamber outer surface to which the sash support frame is attached to the outer wall surface. By interposing the sash support frame of the present invention between the window frame and the outer wall material, the accommodation of the end surface of the outer wall material can be processed by filling a sealing material between the outer wall material and the sash support frame. Therefore, even in the outer insulation method in which the estimated size from the frame to the outer wall material is larger than that in the inner insulation method, the sash support frame can absorb the difference in size, and the window frame itself can be the same in each method. Since it can be used, the number of window frames can be reduced, and the manufacturing cost and management cost can be reduced. In addition, the sash that incorporates a large number of double glazings can be stably supported for a long period of time, the on-site work such as sticking waterproof tape can be saved, the construction period can be shortened, and the cost can be reduced. The same effect as the outer wall structure can be obtained.

部分に流れ落ちるため、前述の通り外部に排出できる。Here, the support lower frame 12, as shown in FIG. 4, comprises two hollow portions and a concave groove portion 123. Then, the upper surface of the first hollow portion, that is, the groove portion 1
The bottom surface of 23 is an inclined surface that decreases toward the outdoor side. Therefore, if a water drainage hole is formed in the outdoor-side upright portion 123B that divides the recessed groove portion 123 and the second hollow portion, the contact portion between the support lower frame 12 and the outdoor end of the window lower frame 22 will be temporarily moved. Even if water enters, the water is collected in the groove 123, flows along the inclined surface, and can be discharged to the outside of the wall through the second hollow portion. That is, the recessed groove portion 123 has a certain depth and a certain volume so that the water does not overflow to the indoor side even if a certain amount of water enters. The stepped portion 113 of the upper support frame 11 is inclined so as to move away from the upper surface of the upper window frame 21 toward the indoor side. And the sealing material 1 on the indoor side
Reference numeral 14 is in contact with a mounting piece 214 that stands upright from the upper surface of the window upper frame 21. For this reason, the window upper frame 2
Even if rainwater infiltrates from the contact portion between the outer frame 1 and the outdoor part 113B due to the capillary phenomenon or the like, the space between the window upper frame 21 and the support upper frame 11 becomes large due to the inclined surface, so that the capillary phenomenon occurs at that portion. Does not occur, and since the rainwater is blocked by the mounting piece 214, it is possible to prevent the water from leaking to the indoor side. Similarly, in the support vertical frame 13, the step portion 133 is also obliquely inclined so as to move away from the side surface (vertical surface) of the window vertical frame 23 toward the indoor side. The sealing material 134 on the indoor side is the mounting piece 2 of the vertical window frame 23.
It is in contact with 34. Therefore, even if rainwater enters from the contact portion between the projection 133B and the vertical window frame 23 due to a capillary phenomenon, the rainwater will be absorbed by the vertical window frame 23 and the vertical support frame 13.
Reaches a large space between which the capillary phenomenon does not occur, and falls downward due to gravity, and the concave groove portion 123 of the supporting lower frame 12 is reached.
As it flows down to a part, it can be discharged to the outside as described above.

く、工程調整も不要にでき、工期短縮も実現できる。According to this embodiment, the following effects can be obtained. (1) In the outer insulation method, the window frame 20 is not directly attached to the frame of the building but is attached via the sash support frame 10. Therefore, the sash support frame 10 is used for parting off the outer wall material 7. Can be done by For this reason,
Unlike the prior art, the window frame used in the outer insulation method does not need to have a larger prospective dimension than the window frame in the inner insulation method, and the window frame 20 common to each method can be used. The number of types can be reduced, and manufacturing costs and management costs can be reduced. Furthermore, the position of the window frame 20 is almost the same as when the mounting pieces 214, 224, 234 of the window frame 20 are directly mounted on the building body (column 2, lintel 3, window stand 4), so the window frame 20 Window frame 20 such as 217, 227, 237
The interior of the room can be shared with the case of the internal insulation method, and these accessories can also be shared. For this reason,
Regardless of whether the inner insulation construction method or the outer insulation construction method is adopted, accessories such as the window frame 20 and the window frames 217, 227, 237 can be shared, so that the number of parts can be reduced and the cost can be reduced. Management from design to construction can be labor-saving. (2) Since the window frame 20 is fixed to the sash support frame 10 made of aluminum, it is possible to improve the support strength as compared with the case where it is supported by a conventional wooden connecting plate material, and a large weight of double glazing glass. Even a sash incorporating 34 can be stably supported for a long period of time. In addition, since the window frame 20 may be attached to the sash support frame 10 in advance, the sash support frame 10 with the window frame 20 integrated may be attached to the skeleton of the building. On-site work can be reduced, work costs can be reduced, the construction period can be predicted easily, process adjustments can be eliminated, and the construction period can be shortened.
