Japanese Patent No. 5419790

  By the way, in general, in a joint formed by adjacent outer wall materials on the outer wall of a building, a gasket which is a fixed sealing material is used as a water stop means, whereas it is formed between the outer wall materials around the door frame. In such joints, a wet sealant is used as a water stop means. This is presumably because the joint space is formed around the door frame depending on the shape of the door frame, so that it is difficult to install the fixed sealing material. Further, if there is a protruding portion that protrudes into the joint space in the door frame, there is a concern that the fixed sealing material may be crushed by the protruding portion and the fixed sealing material may be damaged.

  The present invention has been made in view of the above circumstances, and its main purpose is to ensure high water stopping performance at the joint between the outer wall surface material around the joinery frame while simplifying the configuration. An object is to provide a joiner frame mounting structure for a building.

  Hereinafter, means and the like effective for solving the above-described problems will be described while showing functions and effects as necessary. In the following, for ease of understanding, the reference numerals of the corresponding components in the embodiments of the invention are appropriately shown in parentheses, but are not limited to the specific configurations shown in parentheses.

1st invention is the fitting frame attachment structure of the building (10) by which a fitting frame (14) is attached to the opening part (12) for entrances and exits formed in the building outer wall (11),
The building outer wall includes a plurality of outer wall members (21) having an outer wall surface material (22) and an outer wall frame (23), and an inner wall member (24) provided on the indoor side of the outer wall member. In the matching outer wall member, the outer wall frames are connected to each other,
A position of a base frame (31), which is a base for mounting the joinery frame, is fixed to the outer wall frame of the outer wall member adjacent to the opening, and is arranged side by side with the outer wall surface material on the outdoor side of the base frame The joinery frame is provided in
The indoor side surface facing the indoor side in the base frame is located at the same position in the wall thickness direction with respect to the indoor side surface of the outer wall frame, whereas the outdoor side surface facing the outdoor side and serving as the attachment surface of the joinery frame Is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame, and a gasket (27) is attached to a joint between the outer wall surface material and the joinery frame.

  When a joinery frame is attached to the opening of the building outer wall, in order to simplify the configuration, the outer wall frame and the base frame are fixed in the same manner as the outer wall frames are fixed to each other by adjacent outer wall members. It is desirable that In this case, the indoor side surface of the base frame and the indoor side surface of the outer wall frame are at the same position in the wall thickness direction, so that the same surface of the frame is used as a reference from the indoor side area of the outer wall member to the indoor side area of the joinery frame. Thus, the inner wall member can be provided and the inner wall member in the vicinity of the opening can be easily attached.

  Moreover, regarding the water stop structure around the joinery frame, the outer wall surface material of the outer wall member and the joinery frame are arranged side by side, and a gasket (a fixed water stop member) is provided at a joint formed between them. In this case, depending on the shape and position of the joinery frame, there is a concern that a biased pressing with respect to the gasket occurs, and that the gasket may be damaged.

  In this respect, in the present invention, the outdoor side surface that faces the outdoor side of the base frame and serves as the attachment surface of the joinery frame is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame. Joints will be formed at sites that are difficult to receive. Therefore, it is possible to suppress the occurrence of uneven pressing on the gasket, and the gasket can be appropriately attached at the joint between the outer wall surface material and the joinery frame. As described above, high water-stopping performance can be ensured at the joint between the outer wall surface material around the joinery frame while simplifying the configuration.

  In the above configuration, the joinery frame is provided with a water-stop portion that stops water on the base frame in the vicinity of the boundary between the outer wall frame and the base frame, so that rainwater from between the joinery frame and the base frame, etc. Can be prevented. In this case, an appropriate water-stopping structure can be realized around the joinery frame by making the joint gasket between the outer wall surface material and the joinery frame a primary seal and a water-stop portion for the base frame in the joinery frame as a secondary seal. .

  Here, in the joinery frame, when the water stop portion is provided in the protruding portion that protrudes to the outer wall frame side rather than the side surface portion, the water stop portion near the boundary between the outer wall frame and the base frame is joined. This is a preferable configuration for stopping water. In this case, in the structure in which the water stop portion of the joinery frame protrudes to the joint side, there is a concern about interference between the protruding portion (water stop portion) and the gasket in the joint, but as described above, the outdoor side surface of the base frame Is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame, the protruding portion (water stop portion) and the gasket do not interfere with each other, and the damage of the gasket due to the interference can be suppressed.

  According to a fourth aspect of the present invention, in the joinery frame, the side surface portion is separated from the outer wall frame, whereas the protruding portion is in contact with the outer wall frame.

  Since the side surface portion of the joinery frame is separated from the outer wall frame, it is easy to secure a desired joint size when forming the joint between the outer wall surface material and the side surface portion of the joinery frame. Further, since the protruding portion is in contact with the outer wall frame, the position of the water stop portion is as close as possible to the outer wall frame side, which is advantageous in securing water stop performance at the boundary portion between the outer wall frame and the base frame. It becomes.

  According to a fifth aspect of the present invention, the joinery frame includes a frame main body (41) opposed to a peripheral end surface of the door member (15), and an eye plate member (42, 42) provided on the opposite side of the door member across the frame main body. 43), and the frame body has an extension portion (41c) that overlaps the base frame on the indoor side of the eye plate member, and the eye plate member is integrated with the frame body. The distal end portion of the extending portion protrudes to the outer wall frame side as the protruding portion from the side surface portion formed by the eye plate member.

  In the above configuration, the joinery frame includes a frame body facing the peripheral end surface of the joinery, and a face plate member provided on the opposite side of the door member across the frame body, and the frame body extends further. Has a protruding part. In this case, since the extending portion extends so as to overlap the base frame on the indoor side of the eye plate member, the extension portion can be easily fixed to the base frame (and hence the water stop portion). In addition, in the state in which the eye plate member is integrated with the frame body, the distal end portion of the extending portion becomes a protruding portion and protrudes to the outer wall frame side from the side surface portion of the eye plate member. A suitable water stop can be realized in the vicinity of the boundary of the joint with the frame.

  According to a sixth aspect of the present invention, the outer wall frame and the base frame are each made of channel steel, and the webs of the respective frames are joined together so that the web width of the outer wall frame is the same as the base frame. What is smaller than the web width is used.

  In the above configuration, since the web width of the base frame is smaller than the web width of the outer wall frame, the indoor side surface of the base frame is at the same position in the wall thickness direction with respect to the indoor side surface of the outer wall frame, and A configuration in which the side surface is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame can be easily realized.

The indoor side extending portion 41 b is a portion that supports the door weather strip 47 provided on the indoor side of the door body 15.

  The outer wall side extending portion 41 c is a portion to which the eye plate receiver 43 is coupled. Further, the outer wall side extending portion 41 c is a portion extending so as to overlap the outdoor side flange of the base frame 31 on the indoor side of the eye plate receiver 43, in other words, between the eye plate receiver 43 and the base frame 31. It is a part which overlaps both of these. In a state where the eye plate receiver 43 is coupled to the outer wall side extending portion 41c, the engagement portion 41d provided on the outer wall side extending portion 41c side is engaged with the engagement portion provided on the eye plate receiver 43 side. The joining portion 43a is engaged, whereby the joined state of both members is maintained. Further, in a state where the eye plate receiver 43 is coupled to the outer wall side extending portion 41 c, they overlap in the wall thickness direction, and in this state, the outer wall side extending portion 41 c and the eye plate receiver 43 are attached to the base frame 31. On the other hand, it is fixed with screws 48.

  Further, a housing portion 41e is formed at the distal end of the outer wall side extending portion 41c on the indoor side, that is, the side facing the base frame 31, and a long plate-like gasket 49 is housed in the housing portion 41e. ing. In this case, in a state where the vertical frame body 41 is attached to the base frame 31, the gasket 49 seals (stops water) the outdoor side flange surface of the base frame 31.

  In a state in which the eye plate receiver 43 is integrated with the vertical frame body 41, the front end portion of the outer wall side extending portion 41c protrudes from the end surface (corresponding to the side surface portion) of the eye plate receiver 43, and the front end portion is the outer wall frame. 23 abuts against the outer surface of the web. Accordingly, water can be stopped at the door frame 14 on the outer wall panel 21 side, that is, in the vicinity of the boundary between the outer wall frame 23 and the base frame 31. In this case, the sealing gasket 27 between the outer wall surface material 22 and the door frame 14 is used as a primary seal, and the gasket 49 of the outer wall side extending portion 41c is used as a secondary seal. It is illustrated.

  In addition, the waterproof sheet 50 is stuck continuously from the outdoor side flange of the outer wall frame 23 to the outdoor side flange of the base frame 31. In this case, the waterproof sheet 50 is sandwiched between the outer wall frame 23 and the outer wall surface material 22 on the outdoor flange side of the outer wall frame 23, and the lower frame 31 and the outer wall are positioned on the outdoor flange side of the lower frame 31. A water stop sheet 50 is sandwiched between the side extension 41c.

  A vertical frame plate 42 is attached to the plate holder 43. In this case, in a state where the vertical frame eye plate 42 is coupled to the eye plate receiver 43, the engaged portion 43b provided on the eye plate receiver 43 side is provided on the vertical frame eye plate 42 side. The engaging portion 42a is engaged so that the coupled state of both members is maintained. Further, in a state in which the vertical frame eye plate 42 is coupled to the eye plate receiver 43, the protrusion portion 41 f provided on the vertical frame body 41 side is hooked with the hook portion 42 b provided on the vertical frame eye plate 42 side. As a result, the vertical frame plate 42 is integrated with the vertical frame main body 41. In the state in which the vertical frame plate 42 and the plate holder 43 are integrated, a substantially flat surface is formed by the side surface (the left side surface in the drawing) of these members on the outer wall panel 21 side.

  Further, in the state where the door frame 14 is attached to the outer wall 11, the joint water stop around the door frame 14, that is, the joint water stop between the front end face of the outer wall material 22 and the side surface of the door frame 14 is stopped. In this embodiment, the water stop structure using the gasket 27 is used in the joint as in the joint between the outer wall surfaces 22. That is, generally, the joint around the entrance door may be provided with a wet seal using a caulking material or the like, unlike the joint between the outer wall materials 22, but in this embodiment, the wet seal is used instead. The water is to be stopped with a dry seal. The gasket 27 provided at the joint between the outer wall materials 22 and the gasket 27 provided at the joint around the door frame 14 may be the same member including the cross-sectional shape, or may be different members. .

  Hereinafter, the water stop structure around the door frame 14 will be described in detail. In addition, the structure of FIG. 5 is demonstrated previously as a comparative example of a water stop structure, and the structure of this embodiment is demonstrated after that. 5A is a cross-sectional view showing a configuration of a comparative example in the vicinity of the opening of the outer wall 11, and FIG. 5B is a cross-sectional view showing a configuration of joints around the door frame.

  In FIG. 5A, the configuration of the base frame 31 is different from the configuration of FIG. 3, and in the configuration of FIG. 3, a grooved steel having a size smaller than that of the outer wall frame 23 (that is, the base frame 31). 5 (a), the base frame 31A is made of the same size steel as the outer wall frame 23. On the other hand, in the configuration shown in FIG. In this case, the outer wall frame 23 and the base frame 31A have the outdoor side flanges arranged side by side at the same position in the wall thickness direction, and in this state, the front side end face of the outer wall surface material 22 and the side surface of the door frame 14 A gasket 27A is provided at the joint between the two.

  Here, a joint space (that is, an accommodation space for the gasket 27 </ b> A) is formed between the entrance-side end surface of the outer wall surface material 22 and the side surface of the door frame 14 depending on the shape of the door frame 14. In the configuration of FIG. 5, as described above, the distal end portion of the outer wall side extending portion 41 c protrudes from the end surface of the eye plate receiver 43, and therefore a part of the joint space is formed by the distal end portion of the outer wall side extending portion 41 c. Is narrowed (see FIG. 5B). That is, a joint having a predetermined width dimension (for example, 10 mm) is formed between the entrance side end surface of the outer wall surface material 22 and the side surface of the door frame 14, but the end portion of the outer wall side extending portion 41c protrudes. As a result, the joint width is narrowed locally.

  Therefore, in the configuration of FIG. 5, in a state where the gasket 27A is housed in the joint space between the entrance side end surface of the outer wall surface material 22 and the side surface of the door frame 14, a part of the gasket 27A is the outer wall side extending portion 41c. It is crushed by the tip. That is, interference between the gasket 27 and the outer wall side extending portion 41c occurs. As a result, the gasket 27A is damaged, and there is a concern that the water stop performance is deteriorated.

  On the other hand, in the configuration of the present embodiment, as shown in FIG. 3, groove steel having a size smaller than the outer wall frame 23 (that is, groove steel having a small web width) is used as the base frame 31. Even if the front end portion of the outer wall side extending portion 41c protrudes, the gasket 27 is suitably provided regardless of the configuration.

  That is, in the configuration of FIG. 3, the outdoor side flange of the base frame 31 is shifted to the indoor side with respect to the outdoor side flange of the outer wall frame 23. Has a structure in which the eye plate support 43) faces each other. In this state, a gasket 27 is provided at the joint between the front end surface of the outer wall surface material 22 and the side surface of the door frame 14. In this case, the end portion of the outer wall side extending portion 41c does not exist in the accommodating portion of the gasket 27, and interference between the gasket 27 and the outer wall side extending portion 41c is avoided.

  The difference between the web width of the outer wall frame 23 and the web width of the base frame 31, that is, the setback amount on the outdoor side of the base frame 31 with respect to the outer wall frame 23 is preferably 5 to 20 mm, for example. Depending on the web width difference between the outer wall frame 23 and the base frame 31, the amount of outdoor protrusion of the door frame 14 with respect to the outer wall surface material 22 changes. In this case, the amount of outdoor protrusion of the door frame 14 is reduced by the amount that the web width of the base frame 31 is made smaller than the web width of the outer wall frame 23.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  In the mounting structure of the door frame 14 on the outer wall 11, the indoor side surface of the base frame 31 and the indoor side surface of the outer wall frame 23 are at the same position in the wall thickness direction, so that the door frame 14 can be moved from the indoor area of the outer wall panel 21. The inner wall panel 24 can be provided up to the indoor area with reference to the same surface of each of the frames 23 and 31, and the inner wall panel 24 in the vicinity of the opening can be easily attached.

  Further, regarding the water stop structure around the door frame 14, the outdoor side surface of the base frame 31 is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame 23. A joint will be formed. Therefore, it is possible to suppress the occurrence of uneven pressing on the gasket 27, and the gasket 27 can be appropriately attached at the joint between the outer wall surface material 22 and the door frame 14. As described above, high water-stopping performance can be secured at the joint between the outer wall surface material 22 around the door frame 14 while simplifying the configuration.

  In addition, since the outdoor side surface of the base frame 31 is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame 23, the amount of outdoor protrusion of the door frame 14 is increased with the door frame 14 attached to the base frame 31. Reduced. Therefore, for example, when the door frame 14 is attached to the building unit at the unit manufacturing factory, it is possible to obtain an effect that the damage of the door frame 14 during transportation of the building unit can be suppressed.

  The side surface portion of the door frame 14 facing the end surface of the outer wall surface material 22 (specifically, the side surface portions of the vertical frame eyeplate 42 and the eyeplate receiver 43) is arranged in the in-plane direction of the outer wall 11. The end face and the outer wall frame 23 are fixed to the base frame 31 so as to face each other. Thereby, in the side part of the door frame 14, a joint is formed not by the corner part but by the intermediate part. Therefore, the gasket 27 is sandwiched between the end surface of the outer wall surface material 22 and the side surface portion of the door frame 14 in an appropriate contact state, and the gasket 27 is also properly formed at the joint between the outer wall surface material 22 and the door frame 14. Can be attached.

  Since the door frame 14 is provided with a gasket 49 that stops water on the base frame 31 in the vicinity of the boundary between the outer wall frame 23 and the base frame 31, intrusion of rainwater or the like from between the door frame 14 and the base frame 31 Can be suppressed. In particular, since the gasket 49 is provided in the protruding portion that protrudes to the outer wall frame 23 side from the side surface portion in the door frame 14, further optimization of the water stop is performed in the vicinity of the boundary portion between the outer wall frame 23 and the base frame 31. Can be planned.

  Here, in the configuration in which a part of the outer wall side extending portion 41c having the gasket 49 protrudes toward the joint, there is a concern about interference between the protruding portion and the gasket 27 in the joint. Since the outdoor side surface is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame 23, the projecting portion and the gasket 27 in the joint do not interfere with each other, and damage to the gasket 27 caused by the interference can be suppressed.

  Since the side surface portion of the door frame 14 is separated from the outer wall frame 23, it is easy to secure a desired joint size when forming a joint between the outer wall surface material 22 and the side surface portion of the door frame 14. It becomes. Further, since the distal end portion (protruding portion) of the outer wall side extending portion 41 c is in contact with the outer wall frame 23, the position of the gasket 49 is as close to the outer wall frame 23 as possible, and the outer wall frame 23 and the base frame 31. This is advantageous in ensuring water stoppage performance at the boundary between the two.

  In the vertical frame main body 41 of the door frame 14, the outer wall side extending portion 41 c extends so as to overlap the base frame 31 on the indoor side of the eye plate receiver 43, so that the outer wall side extending portion 41 c of the base frame 31 Fixing (as a result, fixing of the gasket 49) can be easily performed. Further, in the state in which the eye plate receiver 43 is integrated with the vertical frame body 41, the front end portion of the outer wall side extending portion 41c becomes a protruding portion, and is closer to the outer wall frame 23 side than the side surface portion of the eye plate receiver 43. Since it protrudes, suitable water stop is realizable in the boundary part vicinity of the joining of the outer wall frame 23 and the base frame 31. FIG.

  Since the groove frame steel having a web width smaller than the web width of the outer wall frame 23 is used as the base frame 31, the indoor side surface of the base frame 31 is at the same position in the wall thickness direction with respect to the indoor side surface of the outer wall frame 23. The configuration in which the outdoor side surface of the base frame 31 is shifted to the indoor side with respect to the outdoor side surface of the outer wall frame 23 can be easily realized.
