Description

The present invention relates to building materials, and more specifically to structures for connecting building materials such as frames and stiles.

Shoji and FIX windows are constructed by framing horizontal building materials and vertical building materials around four sides of a face material such as glass. As a method for connecting horizontal building materials and vertical building materials, it is common to arrange horizontal building materials between the vertical building materials and connect them to each other. Each building material is provided with an integrally molded plate-shaped abutment part on one edge in the perspective direction, for example, the edge on the outdoor side, and a ridged edge on the other edge in the perspective direction, for example, the edge on the indoor side. is mounted, and the edge of the face material is supported between the plate-like contact portion and the ridge (see, for example, Patent Document 1). Note that the expected direction is a direction along the depth of the fittings.

Chinese Utility Model No. 209483036

By the way, some building materials are designed to improve their strength by providing hollow parts along their length. For example, in Patent Document 1, a hollow part is provided in a horizontal building material. Here, as described in Patent Document 1, the end surface of the plate-like contact part provided on the building material in the vertical direction comes into contact with the plate-like contact part provided on the building material in the horizontal direction. In the case of coupling, it is sufficient to simply cut the plate-like contact portions of the building materials in the vertical direction. However, in fittings, for example, when connecting plate-like abutting parts of vertical frames with continuous plate-like abutting parts having hollow parts, there are cases where the plate-like abutting parts provided on vertical building materials On the other hand, there are some that are connected so that the end surfaces of the plate-like contact portions provided on the horizontal building materials are in contact with each other. In this case, it is necessary to cut the plate-shaped abutment part with respect to the horizontal building material, and also cut out the wall part located on the extension of the plate-shaped abutment part in the hollow part. Therefore, in such a connection structure, the end portion of the hollow portion provided in the horizontal building material is opened, and this open portion is covered with the plate-like contact portion provided in the vertical building material. It is fine if the vertical building materials and the horizontal building materials are molded with high accuracy and these building materials are connected with high precision, but depending on errors in molding or connecting, the hollow part may remain open. There is a concern that water may enter through the hollow portion, leading to problems with watertightness. The above-mentioned problem is not limited to the case where a hollow part is provided only in the horizontal building material, but when the plate-like contact part of the first building material that does not have a hollow part is continuous, If a second building material having a hollow portion is connected to a first building material, the same problem may occur regardless of the extending direction of the building material.

In view of the above-mentioned circumstances, the present invention aims to provide a fitting in which a first building material and a second building material are connected in a state in which the plate-like abutment portion of the first building material, which does not have a hollow portion, is continuous, without compromising watertightness.

In order to achieve the above-mentioned object, the fitting of the present invention comprises a first building material having a plate-shaped abutment portion extending inward from one edge portion in the projection direction and arranged so that its inner surface faces one surface of the face material, and a second building material having a hollow portion provided along its length, in which the first building material and the second building material are connected to each other with the second building material protruding from the part that is on the inner periphery of the first building material, and an end portion of the second building material is joined to the first building material with the outer surface along the projection direction of the wall portion that constitutes the hollow portion facing the inner surface of the plate-shaped abutment portion, and an attachment is attached to the outer surface of the second building material with its end face facing the extended end portion of the plate-shaped abutment portion, and the attachment extends inward from one edge portion in the projection direction of the second building material so as to face one surface of the face material .

According to the present invention, since the plate-like contact portion of the second building material is molded as a separate attachment, the plate-like contact portion of the first building material is continuous without cutting out the hollow portion of the second building material. It becomes possible to connect the second building material and the first building material in this state, and there is no fear that watertightness will be impaired.

The fittings illustrated here are called continuous windows, which are constructed by arranging three independent frames 10A, 10B, and 10C side by side on the left and right, and connecting them to each other via a connecting member 1. It has a rectangular shape close to a square.

The frame body 10A, located on the left side when viewed from the outside, is formed into a rectangular shape by framing all around with left and right vertical frames (first building materials) 11A, 12A that are connected vertically and top and bottom, and top and bottom horizontal frames 13A, 14A that are arranged between the vertical frames 11A, 12A. Furthermore, two interlocking members (second building materials) 15A, 16A are arranged above and below between the vertical frames 11A, 12A, and support rectangular surface materials 17 on the upper, middle, and lower levels. Similarly, the frame body 10B arranged in the center is rectangular by framing the four sides of the left and right vertical frames (first building materials) 11B, 12B that are continuous from top to bottom, and the upper and lower horizontal frames 13B, 14B that are arranged between the vertical frames 11B, 12B, and further two upper and lower joiners (second building materials) 15B, 16B are arranged between the vertical frames 11B, 12B, and the upper, middle, and lower stages support rectangular surface materials 17. The frame body 10C arranged on the right side is rectangular by framing the four sides of the left and right vertical frames 11C, 12C that are continuous from top to bottom, and the upper and lower horizontal frames 13C, 14C that are arranged between the vertical frames 11C, 12C, and further two upper and lower joiners 15C, 16C are arranged between the vertical frames 11C, 12C, and the upper, middle, and lower stages support rectangular surface materials 17. These frame bodies 10A, 10B, 10C have in common that the upper and lower horizontal frames 13A, 14A, 13B, 14B, 13C, 14C and two interlocking members 15A, 16A, 15B, 16B, 15C, 16C each protrude from the inner periphery of the vertical frames 11A, 12A, 11B, 12B, 11C, 12C and are connected to each other. The dimensions along the length of the vertical frames 11A, 12A, 11B, 12B, 11C, 12C and the dimensions along the length of the horizontal frames 13A, 14A, 13B, 14B, 13C, 14C are almost the same for the three frame bodies 10A, 10B, 10C, and the vertical positions of the interlocks 15A, 16A, 15B, 16B, 15C, 16C and the interlocks 15A, 16A, 15B, 16B, 15C, 16C are also almost the same for the three frame bodies 10A, 10B, 10C.

The frame body 10A located on the left side as viewed from the outside and the frame body 10B located in the center have fixed windows formed by the upper, middle, and lower sections using the surface material 17. The frame body 10C located on the right side as viewed from the outside has fixed windows formed by the surface material 17 on the upper and lower sections. The middle section of the frame body 10C located on the right side has a shoji screen 20 supported on all four sides of the surface material 17 by left and right vertical frames 21, 22 and upper and lower horizontal frames 23, 24. Although not shown in the figure, this shoji screen 20 forms a vertical sliding window that opens to protrude to the outside of the room using an opening and closing mechanism installed between the frame body 10C. The left and right vertical frames 11C, 12C and upper and lower transoms 15C, 16C on which the shoji screen 20 is installed have door stops 18 that protrude from the edges located on the inside of the room toward the inner periphery. These door stoppers 18 are configured so that their inner peripheral edges are almost flush with the inner peripheral edges of the frames 21, 22, 23, and 24 that make up the shoji screen 20, and can cover and conceal the frames 21, 22, 23, and 24 of the shoji screen 20 when viewed from inside the room. As is clear from the figure, the surface materials 17 used for these eight fixed windows and the surface material 17 used for one sliding window are configured so that the outer dimensions and dimensions along the projection direction are almost the same, and each is disposed in a position that is biased toward the outside of the room from the middle of the frames 10A, 10B, and 10C in the projection direction. In the example shown in the figure, double-glazed glass is used for all the surface materials 17, but surface materials other than double-glazed glass may be used. In addition, the reference number 19 in the figure denotes a setting block that positions the surface material 17 relative to the frame bodies 10A, 10B, and 10C, the transoms 15A, 16A, 15B, 16B, 15C, and 16C, and the shoji screen 20, and is arranged so as to partially abut the end surface 17a of the surface material 17 at an appropriate location.

The "visible direction" here is the direction along the depth of the fixture, as shown by arrow A in the figure. A surface along the visible direction may be referred to as a "visible surface." In this embodiment, the term "finding direction" is also used. In the case of something that extends horizontally, such as horizontal frame 13A or lattice 15A, the "finding direction" is the direction along the top and bottom perpendicular to the visible direction. In the case of something that extends vertically, such as vertical frame 11A, the "finding direction" is the horizontal direction perpendicular to the visible direction. A surface along the visible direction may be referred to as a "finding surface."

In this embodiment, the above-mentioned horizontal frames 13A, 14A, 13B, 14B, 13C, 14C, vertical frames 11A, 12A, 11B, 12B, 11C, 12C, lattice beams 15A, 16A, 15B, 16B, 15C, 16C, horizontal frames 23, 24, vertical frames 21, 22 (hereinafter, when these are collectively referred to, simply as building materials M) are configured to include an outdoor element M1 arranged on the outdoor side, an indoor element M2 arranged on the indoor side, and a connecting element (insulating material) M3 arranged between the outdoor element M1 and the indoor element M2. The outdoor element M1 and the indoor element M2 are extruded shapes formed from a metal such as an aluminum alloy, and each is configured to have a substantially uniform cross-sectional shape along the entire length along the longitudinal direction. Each of the outdoor element M1 and the indoor element M2 has a hollow portion M1a, M2a in the longitudinal direction over the entire length. The hollow portions M1a, M2a form a space that is closed around the periphery and open only at both end faces of the building material M. The connecting element M3 is molded from a heat insulating material such as resin, and constitutes each building material M by connecting the outdoor element M1 and the indoor element M2 that are molded separately. The connecting element M3 is configured so that the dimension along the projection direction is approximately the same for all building materials M. In this embodiment, the dimension along the projection direction of the outdoor element M1 is configured to be shorter than that of the indoor element M2 so that the connecting element M3 is arranged opposite the end face 17a of the face material 17.

As in this embodiment, if all the building materials M are composed of an outdoor element M1, an indoor element M2, and a connecting element M3, by changing the connecting element M3 to one having a different dimension in the perspective direction, the outdoor element It is possible to configure a plurality of types of fittings having different dimensions in the prospective direction without changing M1 and indoor element M2.

In this embodiment, battens having the same configuration (hereinafter referred to as horizontal battens 30A when distinguishing) are applied to the horizontal building materials M such as the horizontal frames 13A, 14A, 13C, 14C and the lattice 15A, 16A, 15C, 16C, and battens having the same configuration but different from that applied to the horizontal building materials M (hereinafter referred to as vertical battens 30B when distinguishing) are applied to the vertical frames 11A, 12A. For the shoji screen 20, the horizontal battens 30A are applied to both the vertical frames 21, 22 and the horizontal frames 23, 24. The horizontal spur 30A is formed by integrally molding the support portion 31, the inner engagement piece 32, the outer engagement piece 33, and the cover portion 34. The support portion 31 extends from the exterior element M1 toward the inner periphery along the viewing direction, and is arranged to face the outer surface 17c of the surface material 17. The inner engagement piece 32 and the outer engagement piece 33 engage with the spur engagement portion M1b provided on the exterior element M1, thereby maintaining the horizontal spur 30A attached to the exterior element M1. The vertical spur 30B has the same support portion 31, inner engagement piece 32, and outer engagement piece 33 as the horizontal spur 30A, but has an auxiliary cover portion 35 instead of the cover portion 34. The auxiliary cover portion 35 extends toward the outer periphery as an extension of the support portion 31, and is provided so that the surface facing the outside of the room is located on the same plane as the support portion 31, and is configured to have a shorter extension length than the cover portion 34.

The outer surfaces along the facing direction coincide with each other, and these outer surfaces constitute the facing surface 11Ba facing the outdoors. The distance 11Bc from the finding surface 11Ba of the vertical frame 11B facing the outdoors to the finding surface 11Bb of the indoor element (first indoor element) M2 facing the indoors via the connecting element (insulating material) M3 is the expected distance of the frame 10B. Matches the dimension along the direction.

On the other hand, the outdoor element (second outdoor element) M1 of the vertical frame 15B has a dimension along the direction of the vertical frame 11B that corresponds to the plate thickness of the fixed contact portion M1c provided on the vertical frame 11B. It is configured to be shorter than element M1. The dimensions along the prospective direction of the indoor element (second indoor element) M2 and the connecting element (insulating material) M3 of the open space 15B are almost the same as those of the vertical frame 11B. Therefore, the distance 15Bc from the outer surface along the finding direction of the wall located on the outdoor side in the hollow part M1a, which is the finding surface 15Ba of the outdoor element M1, to the finding surface 15Bb facing indoors of the indoor element M2 is is shorter than the dimension along the expected direction.

When connecting the blind 15B configured as described above to the vertical frame 11B, as shown in FIG. 7-1 and FIG. Processing is performed to cut out the support rib M1d. Further, the edge engaging portion M2d provided on the indoor element M2 is also processed to remove all of the area in which the blind 15B is provided.

If a screw is screwed into the screw hole Mc of the blank 15B through the vertical frame 11B from this state, the blank 15B protrudes from the prospective surface 11Bd which is the inner peripheral side of the vertical frame 11B, as shown in Figure 7-3. The two can be connected to each other in the state. At this time, the finding surface 11Bb of the vertical frame 11B facing the interior and the finding surface 15Bb of the blind 15B facing the room are in agreement with each other, and in the outdoor element M1 of the blind 15B, the outer surface 15Ba of the hollow portion M1a facing the outdoors is , comes into contact with the inner surface M1f facing the interior of the fixed abutting portion M1c with the support rib M1d removed. Therefore, from this state, if separate fixed contact members 50 are attached to the respective attachment engaging portions M1e of the upper and lower hollow portions M1a exposed to the outside of the room 15B, as shown in FIG. The vertical frame 11B and the blind 15B can be connected in a state where the fixed abutting portion M1c of the vertical frame 11B is continuous between the upper and lower horizontal frames 13B and 14B. At this time, by bringing the edge end surface 50a of the fixed abutting member 50 into contact with the extending end surface M1g of the fixed abutting portion M1c protruding from the vertical frame 11B, they can be connected to the outside of each other without a gap between them. The facing outer surfaces 11Ba and 50b are located on substantially the same plane, which is preferable in terms of appearance quality.

As mentioned above, the gable 15B has hollow portions M1a, M2a in both the outdoor element M1 and the indoor element M2, respectively, which is advantageous in improving the strength of the fitting. Moreover, the wall portion located on the outdoor side in the hollow portion M1a of the outdoor element M1 is not cut out, and the gable 15B is connected so that the fixed abutment portion M1c provided on the vertical frame 11B protrudes from the inner peripheral visible surface 11Bd of the vertical frame 11B in a state where it is continuous from top to bottom, so there is no concern that water from outside will seep into the fitting through the hollow portion M1a of the gable 15B.

It is possible to apply in the same way between the eyes 15A and 16A, and also between the vertical frames 11C and 12C and the no eyes 15C and 16C in the right frame 10C. . That is, in the left frame 10A, the ribs 30 protruding from the vertical frames 11A and 12A correspond to plate-like contact portions. Therefore, if the support ribs of the ridges 30 are removed and the blinds 15A and 16A are connected, the ridges 30 of the vertical frames 11A and 12A are continuous between the upper and lower horizontal frames 13A and 14A, and the vertical frame 11A , 12A and the blinds 15A, 16A can be connected. In the right frame 10C, the fixed abutting members 70 protruding from the vertical frames 11C and 12C correspond to plate-like abutting portions. Therefore, by connecting the blinds 15C and 16C with the support ribs of the fixed abutment members 70 removed, the fixed abutment members 70 of the vertical frames 11C and 12C will be connected between the upper and lower horizontal frames 13C and 14C. It becomes possible to connect the vertical frames 11C, 12C and the blinds 15C, 16C in this state. In other words, the attachment may be integrally molded with the building material, or it may be something that is engaged like a rib or something that is fixed with a screw like a fixed abutment member. In addition, when the attachment is a ribbed edge, the opposing attachment does not need to be a ribbed edge, and may be formed integrally with the building material, or may be a separate item fixed with screws.

In addition, in the embodiment mentioned above, although the continuous window provided with three frame bodies 10A, 10B, and 10C is illustrated, this invention is not limited to this. Moreover, although the building material M is exemplified as one in which an outdoor element M1 and an indoor element M2 are connected by a connecting element M3 made of a heat insulating material, it is not necessarily necessary to have a connecting element.
