[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mounting structure for a lower window sash frame and an outer wall material.

[0002]

[Prior art]

 FIG. 2 shows a conventional mounting structure of a lower window sash frame and an outer wall material. In FIG. 2, reference numeral 1 denotes a lower window sash frame as a lower frame of the window frame, which has a drainer 11 projecting to the outside of the room, a downward projecting piece 12 formed on the lower front part, and projecting downward. The lower end on the indoor side is located on the outer surface side of the base material 21 as the lower lateral furring strip. Reference numeral 3 denotes an outer wall material, which is located on the outer surface side of the base material 22 as a vertical furring strip provided below the base material 21 as a lower horizontal furring strip, and is self-drilling screwed from the outer surface side. It is fixed to the base material 22 by a stopper 41. The upper end portion 31 of the outer wall member 3 is disposed between the lower protruding piece 12 and the base material 21 as the lower lateral furring strip, and the upper end portion 31 and the lower protruding piece 12 are connected to each other. A space between them is filled with a waterproof sealing material 5 made of caulking.

FIG. 3 shows another conventional mounting structure of the lower window sash frame and the outer wall material. In FIG. 3, reference numeral 23 is a base material 22 as a vertical furring strip, that is, a base material as a secondary furring strip fixed to the primary furring strip, which is provided to make the mounting surface of the outer wall material 3 flat. There is. In this mounting structure, the outer wall member 3 is fixed to the flat mounting surface 24 of the base member 23 as a secondary furring strip by using a stopper 42 made of a special rivet such as valve tight. Since other configurations are substantially the same as those in FIG. 2, corresponding parts are designated by the same reference numerals and detailed description thereof is omitted.

[0004]

[Problems to be solved by the device]

 However, the conventional mounting structure described in FIG. 2 has the following problems. (1) Since the head portion 41a of the stopper 41 made of a self-drilling screw is exposed to the outer surface side of the outer wall material 3 below the lower protruding piece 12, the head portion 41a can be seen from the outside and the appearance becomes poor. Not only that, its head 41a is easily wet by rainwater and easily rusts. (2) When the outer wall material 3 is a heat insulating outer wall material in which a heat insulating material 34 such as a foamed resin is sandwiched between a surface material 32 and a back surface material 33 made of steel plates as shown in the figure, the stopper 41 is the outer wall material. When the outer wall member 3 penetrates the outer wall member 3 and is screwed into the base member 22, the surface member 32 of the outer wall member 3 is recessed to form a recess 35. (3) Rainwater invades from the gap formed at the screwed portion of the stopper 41 in the outer wall material 3, and when the outer wall material 3 is a heat insulating outer wall material, the heat insulating material 34 is moistened to reduce the heat insulating performance, In some cases, rainwater may reach the indoor side. (4) When the outer wall material 3 is a heat insulating outer wall material, the stopper 41 penetrating the outer wall material 3 serves as a heat transfer path and impairs the heat insulating performance of the outer wall material 3.

The other conventional mounting structure described with reference to FIG. 3 has the following problems. (1) Since a special rivet such as a valve tight is used for the stopper 42, not only the stopper 42 becomes expensive, but also a large number of stoppers 42 are required to fix the outer wall material 3 per sheet. Further, a special tool dedicated to the stopper 42 is required, and an additional base material 23 as a secondary furring strip must be provided in order to make the mounting surface of the outer wall material 3 flat. (2) Since the stopper 42 made of a special rivet such as valve tight tightens only the back surface material 33 of the outer wall material (heat insulating outer wall material) 3, the heat insulating material 34 is peeled from the back surface material 33 or the surface material 32 is removed. May be pulled toward the interior of the room and the surface material 32 may be distorted as shown by the phantom line A in FIG. (3) Since it is necessary to make a pilot hole on the back side of the outer wall member 3 and fasten the stopper 42 made of a special rivet such as valve tight to the pilot hole, not only is it difficult to perform the construction, but also the outer wall member 3 It is necessary to construct scaffolds on both the front and back sides of the construction.

By the way, Japanese Patent Laid-Open No. 4-261989 discloses a head part of a stopper in which a cover plate that straddles an outer wall material and a lower protruding piece is attached, and the outer wall material is fixed to a base material by the cover plate. It is described to cover. However, this device has a problem that the head of the rivet is exposed to the outside to make it unattractive because the cover plate is fixed to the lower projecting piece with a rivet.

The present invention basically employs the mounting structure described with reference to FIG. 2, but an object thereof is to solve the above-mentioned various problems all at once with a very simple structure. To do.

[0008]

[Means for Solving the Problems]

 The mounting structure of the lower window sash frame and the outer wall material according to the present invention includes a lower projecting piece formed on the lower front portion of the lower window sash frame and a lower projecting piece provided on the indoor side of the lower projecting piece. In the mounting structure of the outer wall material and the lower window sash frame for arranging the upper end portion of the outer wall material between the base material and the base material, there is a mounting portion projecting to the outside of the room at the upper part of the vertically extending receiving plate body. The receiving plate body of the receiving plate is positioned on the outer surface of the upper end portion of the outer wall material, and the upper end portion of the outer wall material is attached to the base material with a fastener such as a screw from the outer surface of the receiving plate body to cover the front side of the fastener. Of the cover plate having an attachment piece to be attached to the attachment portion of the receiving plate on the upper portion of the cover plate body extending downwardly and attached to the attachment portion of the receiving plate with a fastener such as a screw. Fill the space between the upper part and the lower protruding piece with a waterproof sealing material, and the space between the lower part of the cover plate and the outer wall material. It is obtained by filling a waterproof sealing material.

[0009]

[Action]

 According to the above configuration, the following effects are achieved. (1) The cover plate helps to hide the heads of fasteners such as screws that attach the outer wall material to the base material so that they cannot be seen from the outside. In addition, the space between the upper part of the cover plate and the lower protruding piece, and the space between the lower part of the cover plate and the outer wall material are filled with waterproof seal material, so the head of the stopper may get wet with rainwater or the outer wall material. Since rainwater is prevented from reaching the screwed part of the stopper to the head, it is prevented that the head of the stopper gets wet with rainwater and rusts or rainwater enters the screwed part. (2) Since the upper wall of the outer wall member is located on the outer surface and the upper end of the outer wall member is attached to the base material from the outer surface of the receiving plate main body with the stopper, a dent may be formed in the outer wall member by tightening the stopper. This is prevented by the backing plate body.

[0010]

【Example】

 FIG. 1 shows a mounting structure of a lower window sash frame and an outer wall material according to an embodiment of the present invention. Since this mounting structure basically complies with the mounting structure described with reference to FIG. 2, parts corresponding to those in FIG. 2 are designated by the same reference numerals. Next, differences from the mounting structure shown in FIG. 2 will be mainly described.

In this mounting structure, in addition to the members used in the mounting structure of FIG. 2, a receiving plate 6, a cover plate 7, and waterproof sealing materials 81 and 82 made of caulking material are used.

The backing plate 6 has a backing plate main body 61 and a mounting portion 62 on the top of the backing plate main body 61, and the backing plate main body 61 is projected above the outer wall member 3 in a posture extending in the vertical direction. The outer wall member 3 is positioned on the outer surface of the upper end portion 31 of the outer wall member 3 in this state, and the stopper 41 made of a self-drill screw is driven (screwed) from the outer surface of the receiving plate body 61 to move the upper end portion 31 of the outer wall member 3 to the vertical furring strip. Is attached to the base material 22. As described above, when the stopper 41 is screwed into the outer wall material 3 or the base material 22 from the outer surface of the receiving plate body 61, the situation where the receiving plate body 61 or the outer wall material 3 is recessed and a dent is not caused. Further, the mounting portion 62 projects to the outside of the room.

After attaching the receiving plate 6 and the outer wall member 3 with the stopper 41, the cover plate 7 is attached. The cover plate 7 has a cover plate body 71 and a mounting piece 72, and the cover plate body 71 is positioned so as to cover the front of the stopper 41 and extend downward thereof. Is attached to the attachment portion 62 of the receiving plate 6 with a stopper 9 such as a screw.

The space between the upper part of the cover plate 7 and the lower protruding piece 12 of the lower window sash frame 1 is filled with the waterproof sealing material 81, and the space between the lower part of the cover plate 7 and the outer wall member 3 is filled. The waterproof sealing material 82 is filled in the above.

With this configuration, the cover plate 7 covers the head portion 41 a of the stopper 41 that attaches the outer wall member 3 to the base material 22, so that the head portion 41 a of the stopper 41 cannot be seen from the outside. It looks good. Since the stopper 41 is housed in the closed space surrounded by the cover plate 7, the receiving plate 6 and the waterproof sealing material 82, the head 41a of the stopper 41 is wetted by rainwater or the stopper 41 against the outer wall member 3 is covered. The rainwater is prevented from reaching the screwed-in portion, so that the head 41a of the stopper 41 gets wet with rainwater and rusts, or rainwater penetrates into the screwed-in portion and the outer wall material (insulated outer wall material) The situation of impairing the heat insulation performance does not occur.

By the way, in this embodiment, the lower end portion of the cover plate body 71 is folded back inward, and the waterproof sealing material 82 is filled between the folded back piece portion 73 and the outer wall member 3. By doing so, the lower end surface of the cover plate main body 71 is housed in the closed space and is not exposed to the outside, so there is an advantage that the end surface does not get wet and get rusted. It should be noted that at least the outer surface of the cover plate 7 is subjected to rust prevention treatment such as painting.

Further, in this embodiment, a gap S 1 is secured between the cover plate body 71 and the head 41a of the stopper 41. Therefore, the heat inside the room is prevented from directly escaping to the outside through the stopper 41, and even if the outer wall material 3 is a heat insulating outer wall material, it is driven into the outer wall material 3. The stopper 41 does not significantly reduce the heat insulating performance of the outer wall member 3.

[Effect of device]

 According to the mounting structure of the lower window sash frame and the outer wall material according to the present invention, the following effects are exhibited. (1) The head of a fastener such as a screw that attaches the outer wall material to the base material is covered by the cover plate so that it cannot be seen, so that the appearance is improved. (2) Since the head of the stopper and the screwed-in portion of the stopper are housed in a closed space closed by a cover plate and a waterproof sealing material, the head of the stopper gets wet with rainwater and rusts. Such a situation does not occur. In addition, since rainwater does not enter the screwed part of the stopper, it prevents rainwater from reaching the room through the screwed part, and even if an outer wall material is used as the heat insulating material, its heat insulation performance is improved. Does not decrease significantly. (3) Since the upper wall of the outer wall material is positioned on the outer surface and the upper edge of the outer wall material is attached to the base material from the outer surface of the receiving plate main body with the stopper, the outer wall material will have a dent when the stopper is tightened. Absent. (4) Since it is not necessary to use a special rivet such as a valve tight for mounting the outer wall material, there is no room for the problem of the mounting structure described in FIG.
