Description

The present invention relates to building material shapes and building fixtures.

Some fittings, such as shoji screens, have a frame that supports the edge of a surface material such as a glass sheet between a metal molded part on the outside of the room, which is made of metal, and a resin molded part on the inside of the room, which is made of resin. This type of fitting has the advantage that the metal molded part and the resin molded part suppress heat transfer from the inside to the outside of the room, making it possible to prevent condensation from forming inside the room, for example, even when the temperature outside is lower than the temperature inside the room (see, for example, Patent Document 1).

JP 2006-180269 A

As mentioned above, in fittings where the facing is supported between the metal molded part and the resin molded part, it is necessary to ensure the rigidity of the resin molded part as much as possible when considering wind pressure resistance. This means that the external dimensions of the frame tend to become larger, which not only reduces the lighting area of the shoji screen, but also results in a large amount of exposed frame from the frame, which is undesirable in terms of appearance quality.

In view of the above-mentioned circumstances, the present invention aims to provide a building material and building fixture that can improve insulation and wind pressure resistance without increasing the external dimensions.

In order to achieve the above object, the fitting material of the present invention is a fitting material that supports the edge of a panel by sandwiching it between a metal forming part formed from metal and a resin forming part formed from resin, and the metal forming part has a metal base part arranged along the projection direction, a first metal support wall part arranged to cover one surface of the panel by extending from one edge of the metal base in a direction toward the inner periphery, and a second metal support wall part arranged to cover the other surface of the panel by extending from the other edge of the metal base in a direction toward the inner periphery, and the resin forming part is supported by the metal forming part so as to cover the second metal support wall part.

According to the present invention, the first metal support wall portion and the second metal support wall portion of the metal molding portion are arranged to cover both surfaces of the face material, so there is no need to give the resin molding portion sufficient rigidity to withstand large wind pressure. This allows the resin molding portion to be made smaller, and makes it possible to improve insulation and wind pressure resistance without increasing the external dimensions.

The following describes in detail preferred embodiments of the fittings and fittings according to the present invention with reference to the attached drawings. For convenience, the terms "prospect direction" and "visible direction" may be used below. The "prospect direction" is the direction along the depth of the fittings, as shown by arrow A in the figure. A surface along the prospective direction may be referred to as a "prospect surface." The "prospect direction" is the direction perpendicular to the prospective direction for items that extend horizontally, such as a sill frame. For items that extend vertically, such as a vertical frame, the horizontal direction perpendicular to the prospective direction is called the "prospect direction." A surface along the prospective direction may be called a "prospect surface."

Figures 1 to 5 show a fitting constructed with shaped members according to an embodiment of the present invention. The fitting illustrated here is called a vertical sliding window, and comprises a frame 10 and a paper screen 20. The frame 10 is constructed by assembling an upper frame (shaped member) 11, a lower frame (shaped member) 12, and left and right vertical frames (shaped members) 13 all around. The paper screen 20 is constructed by assembling an upper frame (fittings shaped member: horizontal frame) 22, a lower frame (fittings shaped member: horizontal frame) 23, and left and right vertical frames (fittings shaped members) 24 all around a rectangular surface member 21 such as double-glazed glass.

The upper frame 11, lower frame 12, and left and right vertical frames 13 that make up the frame body 10 are all composite types that include metal frame sections 11M, 12M, and 13M made of extruded shapes formed from metal such as aluminum alloy, and resin frame sections 11P, 12P, and 13P made of extruded shapes formed from resin. Note that the vertical frames 13 in the embodiment are configured to be symmetrical with each other, so the left and right frames will be described with the same reference numerals.

The metal frame portion 11M of the upper frame 11 has an upper frame metal base plate portion 11Ma and an upper frame metal inner peripheral plate portion 11Mb. The upper frame metal base plate portion 11Ma is a flat plate extending almost horizontally along the projection direction. The portion of the outer periphery of the upper frame metal base plate portion 11Ma that faces the outside of the room defines a hollow portion on the outer periphery of the upper frame 11. The upper frame metal inner peripheral plate portion 11Mb is a flat plate extending from approximately the center of the projection surface on the inner periphery of the upper frame metal base plate portion 11Ma toward the inner periphery, and is molded integrally with the upper frame metal base plate portion 11Ma.

The resin frame portion 11P of the upper frame 11 is provided between the inner peripheral edge of the upper frame metal inner peripheral plate portion 11Mb and the interior edge of the upper frame metal substrate portion 11Ma, and has an upper frame resin protrusion portion 11Pa and an upper frame resin substrate portion 11Pb. The upper frame resin protrusion portion 11Pa has a cross section that is approximately rectangular. The upper frame resin substrate portion 11Pb extends from the corner on the outer peripheral side of the upper frame resin protrusion portion 11Pa, which is the interior corner, toward the outer peripheral side, and then extends toward the interior side. This resin frame portion 11P is attached to the inner peripheral portion of the metal frame portion 11M of the upper frame 11, with the upper frame resin protrusion portion 11Pa protruding from the inner peripheral edge of the upper frame metal inner peripheral plate portion 11Mb to the inner peripheral side, and the extended edge of the upper frame resin substrate portion 11Pb protruding beyond the edge of the upper frame metal substrate portion 11Ma to the interior side.

The metal frame portion 12M of the lower frame 12 has a lower frame metal base plate portion 12Ma and a lower frame metal inner peripheral plate portion 12Mb. The lower frame metal base plate portion 12Ma is a plate-like portion that extends in a projected direction and gradually downwards toward the outside of the room. The lower frame outer peripheral hollow portion 12Mc is formed on the outer peripheral side of the lower frame metal base plate portion 12Ma, which faces the outside of the room. The lower frame metal inner peripheral plate portion 12Mb is a flat plate-like portion that extends from approximately the center of the projected surface on the inner peripheral side of the lower frame metal base plate portion 12Ma toward the inner peripheral side. The lower frame inner peripheral hollow portion 12Md is formed on the inner peripheral side of the lower frame metal base plate portion 12Ma, which faces the inside of the room from the lower frame metal inner peripheral plate portion 12Mb.

The resin frame portion 12P of the lower frame 12 is provided to cover the entire inner circumferential surface of the lower frame inner circumferential hollow portion 12Md and extends almost horizontally along the projection direction. The edge portion of the resin frame portion 12P located on the indoor side protrudes further into the room than the portion of the lower frame inner circumferential hollow portion 12Md located on the indoor side.

The metal frame portion 13M of the vertical frame 13 has a vertical frame metal base plate portion 13Ma, a vertical frame metal inner plate portion 13Mb, and a vertical frame metal inner plate portion 13Mc. The vertical frame metal base plate portion 13Ma is a flat plate extending almost vertically along the projection direction. The vertical frame metal inner plate portion 13Mb is a flat plate extending from approximately the center of the projection surface on the inner periphery of the vertical frame metal base plate portion 13Ma toward the inner periphery. The vertical frame metal inner plate portion 13Mc is a flat plate extending from the edge portion on the interior side of the vertical frame metal base plate portion 13Ma toward the inner periphery.

The resin frame portion 13P of the vertical frame 13 is provided to cover the entire inner peripheral surface from the vertical frame inner metal plate portion 13Mb to the vertical frame inner metal plate portion 13Mc, and extends almost vertically along the projection direction. The edge portion located on the indoor side of the resin frame portion 13P of the vertical frame 13 protrudes toward the indoor side beyond the vertical frame inner metal plate portion 13Mc.

As shown in Figures 4 to 8, the upper frame 22, lower frame 23, and left and right vertical frames 24 that make up the shoji screen 20 are, like the frame body 10, composite types that include metal molded parts 22M, 24M made of extruded material molded from a metal such as an aluminum alloy, and resin molded parts 22P, 24P made of extruded material molded from a resin. In the embodiment, the upper frame 22 and the lower frame 23 are configured to be symmetrical to each other, and the vertical frames 24 are configured to be symmetrical to each other. Therefore, only the upper frame 22 and one of the vertical frames 24 will be described, and the lower frame 23 will be given the same reference number as the upper frame 22, and the vertical frames 24 on the left and right will be given the same reference number.

The metal forming part 22M of the upper frame 22 has a horizontal metal base 22Ma, a first horizontal metal support wall part (first metal support wall part) 22Mb, a second horizontal metal support wall part (second metal support wall part) 22Mc, and a horizontal metal outer peripheral wall part 22Md. The horizontal metal base 22Ma has a cross section that is hollow and has a substantially rectangular shape, and is configured so that the long side of the rectangle is along the projection direction. Only one screw hole 22Me is provided inside the hollow of the horizontal metal base 22Ma. The screw hole 22Me is a part into which a screw S is screwed when connecting with the vertical frame 24, and is formed in a corner part on the outer periphery side of the hollow interior and on the exterior side of the room. The first horizontal metal support wall part 22Mb is a plate-like shape that extends in the projection direction from a corner part on the exterior side and on the inner periphery side of the horizontal metal base 22Ma toward the inner periphery side. The extending edge of the first horizontal metal support wall 22Mb is slightly bent toward the inside of the room. The second horizontal metal support wall 22Mc is provided on the part located on the inside of the room on the projection surface on the inner periphery side of the horizontal metal base 22Ma. The base end of the second horizontal metal support wall 22Mc extends toward the inner periphery side and then toward the inside of the room, thereby forming a horizontal groove portion 22Mf that is along the projection direction between the horizontal metal base 22Ma and the horizontal metal base 22Ma and opens to the inside of the room. The tip end of the second horizontal metal support wall 22Mc extends in the projection direction from a part that is outside the room from the projection surface of the horizontal metal base 22Ma facing the room toward the inner periphery side. The protruding dimension of the second horizontal metal support wall 22Mc from the horizontal metal base 22Ma is set to be smaller than that of the first horizontal metal support wall 22Mb. The horizontal metal outer peripheral wall portion 22Md extends in the viewing direction from the corner that is on the outdoor side and on the outer peripheral side of the horizontal metal base portion 22Ma toward the outer peripheral side.

The resin molded portion 22P of the upper frame 22 has a horizontal resin base 22Pa, a horizontal support protrusion 22Pb, a horizontal engagement piece portion 22Pc, and a horizontal hook portion 22Pd. The horizontal resin base 22Pa is in the form of a plate extending along the viewing direction. This horizontal resin base 22Pa has two ribs 22Pe extending along the length of the upper frame 22 on the viewing surface facing the room. The extension length of the horizontal resin base 22Pa is set so that when the outer peripheral edge is abutted against the inner peripheral surface of the horizontal metal base 22Ma, the inner peripheral edge exceeds the second horizontal metal support wall portion 22Mc and is approximately the same as the first horizontal metal support wall portion 22Mb. The horizontal support protrusion 22Pb extends from the inner peripheral edge of the horizontal resin base 22Pa toward the outside of the room. The horizontal engagement piece 22Pc extends from the edge of the horizontal resin base 22Pa toward the outside of the room. The horizontal hook portion 22Pd extends from the visible surface of the horizontal resin base 22Pa facing the outside of the room toward the outside and then bends toward the outside. In more detail, when the edge of the horizontal resin base 22Pa that is the outer periphery is abutted against the visible surface that is the inner periphery of the horizontal metal base 22Ma, the horizontal hook portion 22Pd protrudes toward the outside from a portion that is on the inner side of the tip edge of the second horizontal metal support wall portion 22Mc, and the extended edge of the bent portion is located on the outer side of the tip edge of the second horizontal metal support wall portion 22Mc.

The metal forming portion 24M of the vertical frame 24 has a vertical metal base 24Ma, a first vertical metal support wall portion (first metal support wall portion) 24Mb, a second vertical metal support wall portion (second metal support wall portion) 24Mc, and a vertical metal outer peripheral wall portion 24Md. The vertical metal base 24Ma is a generally flat plate extending in the projection direction. The edge portion of the vertical metal base 24Ma located on the indoor side is slightly bent toward the inner periphery. The first vertical metal support wall portion 24Mb extends in the projection direction from the edge portion of the vertical metal base 24Ma that is on the outdoor side toward the inner periphery. The extending edge portion of the first vertical metal support wall portion 24Mb is slightly bent toward the indoor side. The second vertical metal support wall portion 24Mc is provided on the portion located on the indoor side of the projection surface that is on the inner periphery side of the vertical metal base 24Ma. The base end of the second vertical metal support wall 24Mc extends toward the inner periphery and then toward the interior side, forming a vertical groove 24Me that runs along the front direction between the vertical metal base 24Ma and the vertical metal base 24Ma and opens toward the interior side. The tip of the second vertical metal support wall 24Mc extends from a portion that is on the exterior side of the edge of the vertical metal base 24Ma that faces the interior of the room toward the inner periphery in the approximate front direction. The protruding dimension of the second vertical metal support wall 24Mc from the vertical metal base 24Ma is set to be smaller than that of the first vertical metal support wall 24Mb. The vertical metal outer peripheral wall 24Md extends in the front direction from the edge of the vertical metal base 24Ma that is on the exterior side toward the outer periphery. As is clear from FIG. 6, the distance a from the facing surface of the first vertical metal support wall 24Mb that faces the room to the facing surface of the second vertical metal support wall 24Mc that faces the room is configured to be approximately equal to the distance b from the facing surface of the first horizontal metal support wall 22Mb that faces the room to the facing surface of the second horizontal metal support wall 22Mc that faces the room on the upper frame 22 and the lower frame 23.

As shown in Figures 4 to 8, the resin molded portion 24P of the vertical frame 24 has a vertical resin base 24Pa, a vertical support protrusion 24Pb, a vertical engagement piece 24Pc, and a vertical hook portion 24Pd. The vertical resin base 24Pa is flat and extends along the viewing direction. The extension length of the vertical resin base 24Pa is set so that when the outer peripheral edge is abutted against the inner peripheral surface of the vertical metal base 24Ma, the inner peripheral edge exceeds the second vertical metal support wall 24Mc and is approximately the same as the first vertical metal support wall 24Mb. The vertical support protrusion 24Pb extends from the inner peripheral edge of the vertical resin base 24Pa toward the outside of the room. The vertical engagement piece 24Pc extends from the outer peripheral edge of the vertical resin base 24Pa toward the outside of the room. The vertical hook portion 24Pd extends from the visible surface of the vertical resin base 24Pa facing the outside of the room toward the outside and then bends toward the outer periphery. In more detail, when the edge portion on the outer periphery of the vertical resin base 24Pa is abutted against the visible surface on the inner periphery of the vertical metal base 24Ma, the vertical hook portion 24Pd protrudes toward the outside from a portion that is on the inner periphery side of the tip edge of the second vertical metal support wall portion 24Mc, and the extended edge portion of the bent portion is located on the outer periphery side of the tip edge of the second vertical metal support wall portion 24Mc.

The upper and lower frames 22 and 23 are disposed at the upper and lower edges of the panel 21 in which the glazing channel 1 is disposed, between the first horizontal metal support wall 22Mb and the second horizontal metal support wall 22Mc of the metal molding portion 22M, and the second horizontal metal support wall 22Mc supports the resin molding portion 22P, so that the upper and lower edges of the panel 21 are disposed. When supporting the resin molding portion 22P, the horizontal engagement piece 22Pc is inserted into the horizontal groove portion 22Mf, and then the horizontal hook portion 22Pd is engaged with the second horizontal metal support wall portion 22Mc. If the base end of the second horizontal metal support wall 22Mc is crimped while the horizontal engagement piece 22Pc is inserted into the horizontal groove 22Mf, the horizontal engagement piece 22Pc can be prevented from escaping from the horizontal groove 22Mf, and there is no risk of the resin molded part 22P falling off from the metal molded part 22M. Similarly, the vertical frame 24 is disposed on both side edges of the face material 21 by disposing the left and right side edges of the face material 21, on which the glazing channels 1 are disposed, between the first vertical metal support wall 24Mb and the second vertical metal support wall 24Mc of the metal molded part 24M, and supporting the resin molded parts 24P on the second vertical metal support wall 24Mc.

After the upper frame 22, lower frame 23, and left and right vertical frames 24 are arranged around the four periphery of the facing material 21, the screw S is screwed into the screw hole 22Me of the upper frame 22 and the screw hole 22Me of the lower frame 23 through the vertical metal base 24Ma of the vertical frame 24, respectively, so that the upper frame 22, lower frame 23, and left and right vertical frames 24 are connected to each other, and it is possible to form the shoji screen 20. As shown in Figures 1 to 3, in this embodiment, the edges located on the innermost side of the resin molded portion 22P of the upper frame 22, the resin molded portion 22P of the lower frame 23, and the resin molded portion 24P of the left and right vertical frames 24 are each configured to be located on the outer side of the opening formed by the frame body 10. The shoji 20 is supported so that it can be opened and closed relative to the frame 10 by interposing friction stays 2 between the upper frame 22 and the upper frame 11, and between the lower frame 23 and the lower frame 12. The position of the shoji 20 relative to the frame 10 is adjusted so that when the shoji 20 is closed, the innermost edges of the resin molded part 22P of the upper frame 22, the resin molded part 22P of the lower frame 23, and the resin molded parts 24P of the left and right vertical frames 24 do not protrude from the innermost projection surfaces of the upper frame 11, lower frame 12, and left and right vertical frames 13 that constitute the frame 10. This makes it difficult to see the upper frame 22, lower frame 23, and left and right vertical frames 24 when the fitting is viewed from the inside of the room, which is advantageous in terms of appearance quality and also has the advantage of ensuring a large proportion of the daylighting area.

In the shoji screen 20 constructed as described above, the resin molded parts 22P, 24P are arranged to cover the parts of the second horizontal metal support wall part 22Mc and the second vertical metal support wall part 24Mc that face the room in all of the upper frame 22, lower frame 23, and left and right vertical frames 24, which is advantageous in terms of thermal insulation. This makes it possible to prevent condensation from occurring inside the room, for example, even when the temperature outside the room is lower than the temperature inside the room. Moreover, the first horizontal metal support wall part 22Mb and the first vertical metal support wall part 24Mb of the metal molded parts 22M, 24M are arranged to cover the edge part of the surface of the panel 21 that faces the outside, and the second horizontal metal support wall part 22Mc and the second vertical metal support wall part 24Mc are arranged to cover the edge part of the surface of the panel 21 that faces the room. As a result, the metal molded parts 22M and 24M can withstand strong wind pressure, and there is no need to ensure that the resin molded parts 22P and 24P have sufficient rigidity to withstand strong wind pressure. Therefore, the resin molded parts 22P and 24P do not need to have hollow spaces, and can be simply plate-shaped, making it possible to reduce the size, and improving insulation and wind pressure resistance without increasing the external dimensions of the upper frame 22, lower frame 23, and left and right vertical frames 24.

Furthermore, at each corner of the shoji screen 20, the first horizontal metal support wall portion 22Mb of the upper frame 22 and the first horizontal metal support wall portion 22Mb of the lower frame 23 are joined to the first vertical metal support wall portion 24Mb of the vertical frame 24 on the outside of the room, and the second horizontal metal support wall portion 22Mc of the upper frame 22 and the second horizontal metal support wall portion 22Mc of the lower frame 23 are joined to the second vertical metal support wall portion 24Mc of the vertical frame 24 on the inside of the room. Therefore, even if only one screw S is screwed into each of the screw holes 22Me, there is no risk of the upper frame 22 or the lower frame 23 rotating around the longitudinal axis relative to the vertical frame 24, which is more advantageous in terms of wind pressure resistance.

In the embodiment, a thermal expansion member 30 is disposed in the portion of the first horizontal metal support wall portion 22Mb of the upper frame 22 and the lower frame 23 facing the second horizontal metal support wall portion 22Mc. Similarly, a thermal expansion member 31 is disposed in the portion of the first vertical metal support wall portion 24Mb of the vertical frame 24 facing the second vertical metal support wall portion 24Mc. The thermal expansion members 30, 31 are non-combustible or flame-retardant fire-resistant members that expand due to heat, and are provided continuously over almost the entire length of the first horizontal metal support wall portion 22Mb and the first vertical metal support wall portion 24Mb. As the thermal expansion members 30, 31, for example, a thermally expandable graphite-containing foam material can be used. Therefore, when exposed to high temperatures such as during a fire, the resin molding parts 22P, 24P will melt or burn, but the expanded thermal expansion members 30, 31 can be filled between the first horizontal metal support wall part 22Mb and the second horizontal metal support wall part 22Mc and between the first vertical metal support wall part 24Mb and the second vertical metal support wall part 24Mc. This makes it possible to prevent a fire from penetrating the inside and outside of the room without providing a separate reinforcing material, and improve fire resistance. In the figure, reference numeral 32 denotes a thermal expansion member provided on the visible surface facing the room of the horizontal metal outer peripheral wall part 22Md of the upper frame 22 and the lower frame 23, reference numeral 33 denotes a thermal expansion member provided on the part of the upper frame 11 and the lower frame 12 facing the thermal expansion member 32, and reference numeral 34 denotes a thermal expansion member provided on the visible surface facing the outside of the room of the vertical frame metal inner peripheral plate part 13Mb of the vertical frame 13. Although not shown in the figure, these thermal expansion members 32, 33, and 34 are continuously provided over almost the entire length of the upper frame 22, lower frame 23, upper frame 11, and lower frame 12.

Furthermore, in the upper frame 22 and the lower frame 23, the horizontal metal base 22Ma of the metal molded portion 22M is configured to have a roughly rectangular hollow shape, and the facing surface 22Mg that faces the room is exposed to the outside on the outer periphery side of the resin molded portion 22P. Therefore, when attaching parts to the upper frame 22 or the lower frame 23, processing such as removing the resin molded portion 22P is not necessary, and for example, a metal arm that connects the operating handle 3 for opening and closing the shoji screen 20 and the lower frame 23 can be easily and securely attached to the metal molded portion 22M of the lower frame 23.

In the above-mentioned embodiment, a vertical sliding window is exemplified, but the present invention is not limited to this, and can be applied to other fittings such as sliding windows and fixed windows. In this case, it is not necessarily required to apply it to all four surrounding shaped members (frames and frames), but it is sufficient to apply it to at least one shaped member. Furthermore, when the shaped member of the present invention is used as the frame of a shoji screen, the frame that constitutes the frame body does not necessarily have to include a metal frame portion and a resin frame portion. Furthermore, although the embodiment is arranged to provide thermal expansion members in appropriate locations, it is not necessarily required to provide thermal expansion members.

As described above, the building material shape of the present invention is a building material shape that supports the edge of a panel material by sandwiching it between a metal molding part molded from metal and a resin molding part molded from resin, and is characterized in that the metal molding part has a metal base part arranged along the projecting direction, a first metal support wall part arranged to cover one surface of the panel material by extending from one edge of the metal base in a direction toward the inner circumference, and a second metal support wall part arranged to cover the other surface of the panel material by extending from the other edge of the metal base in a direction toward the inner circumference, and the resin molding part is supported by the metal molding part so as to cover the second metal support wall part.
According to this invention, since the first and second metal support walls of the metal molded part are arranged to cover both surfaces of the face material, it is not necessary to give the resin molded part rigidity to withstand large wind pressure. Therefore, the resin molded part can be made smaller, and it is possible to improve the insulation and wind pressure resistance without increasing the external dimensions.

The present invention is also characterized in that, in the above-mentioned building fixture shape material, the metal base portion is provided with a facing surface that is exposed to the outside and is located on the outer periphery side of the resin molding portion.
According to this invention, it is easy to attach parts to the sight surface of the profile. In this case, the metal base does not necessarily have to be configured to have a hollow portion, and it is sufficient that the sight surface is simply provided along the sight direction from the edge of the metal base.

The present invention is also characterized in that, in the above-mentioned building fixture shape, a thermally expandable member is provided on an inner surface of the first metal support wall portion that faces the second metal support wall portion.
According to this invention, when exposed to high temperatures, the expanded thermally expandable member can be filled between the first metal support wall portion and the second metal support wall portion, making it possible to improve fire resistance without providing a separate reinforcing material.

The present invention is also characterized in that, in the above-mentioned building material, the resin molded portion has an engaging piece portion extending toward the first metal support wall portion on its outer peripheral edge portion, and the second metal support wall portion has a groove portion into which the engaging piece portion can be inserted between the metal base portion, and the resin molded portion is supported by the metal molded portion by engaging the inner peripheral edge portion with the second metal support wall portion with the engaging piece portion inserted into the groove portion.
According to this invention, the molded resin portion can be securely attached to the molded metal portion.

Furthermore, the fitting according to the present invention is characterized in that at least one of the vertical and horizontal frames constituting the shoji screen is made using the fitting shape material described above.
According to this invention, since the first and second metal support walls of the metal molded part are arranged to cover both surfaces of the face material, it is not necessary to give the resin molded part rigidity to withstand large wind pressure. Therefore, the resin molded part can be made smaller, and it is possible to improve the insulation and wind pressure resistance without increasing the external dimensions.

Furthermore, the fitting according to the present invention is characterized in that the above-mentioned fitting shaped material is applied to both of the two vertical frames and two horizontal frames that make up the shoji screen.
According to this invention, it is possible to prevent the size of the resin molded parts from increasing around all four sides, which has the advantage that it is possible to increase the light-gathering area for a shoji screen with the same external dimensions.

The present invention is also characterized in that, in the above-mentioned building fixture, the first metal support wall portion and the second metal support wall portion of the horizontal frame are arranged between the first metal support wall portion and the second metal support wall portion of the vertical frame, and the horizontal frame and the vertical frame are joined in a state in which the first metal support wall portions abut each other and the second metal support wall portions abut each other.
According to this invention, the first metal support wall portion and the second metal support wall portion are overlapped at the joint between the horizontal and vertical frames, which makes the horizontal and vertical frames firmly joined, which is advantageous in terms of wind pressure resistance.

Furthermore, the present invention is characterized in that, in the above-mentioned building fixture, the building fixture shape material constituting the horizontal frame has a hollow metal base, and within the hollow interior of the metal base, there is provided only one screw hole along the longitudinal direction, into which a screw is screwed to connect to the vertical frame.
According to this invention, the external dimensions of the hollow portion can be kept small, making it possible to miniaturize the shoji screen. Moreover, since the first metal support wall portion and the second metal support wall portion are overlapped at the joint between the horizontal frame and the vertical frame, even if a screw is screwed into only one screw hole, there is no concern that the horizontal frame will rotate around the shank of the screw relative to the vertical frame.

Furthermore, the present invention is characterized in that, in the above-mentioned fittings, the shoji screen is arranged relative to the frame body so that the edge portion located on the innermost periphery of the resin molded portion is flush with the innermost visible surface of the shaped material constituting the frame body, or is located more outer than the innermost visible surface of the shaped material constituting the frame body.
According to this invention, it becomes difficult to visually recognize the horizontal and vertical frames that make up the shoji screen, which is advantageous in terms of appearance quality.
