Abstract

[Problem] To provide a mullion structure that can reduce the size in the visible direction while ensuring strength. [Solution] The mullion structure 30 comprises a frame 2, a glass panel 4 disposed within the frame 2, and a mullion 3 disposed to the side of the glass panel 4 and extending in the depth direction. The mullion 3 has a mullion body 31 having an indoor portion 32 disposed on the indoor side X2 of the glass panel 4 and a depth-extending portion 33 that extends from the indoor portion 32 through the glass panel 4 to the outdoor side X1 in the depth direction, an insulating member 34 disposed on the outdoor side X1 of the glass panel 4 and on the outside in the visibility direction of the depth-extending portion 33, and a metal outer metal frame member 35 disposed on the outside of the insulating member 34.

Claims (4)

  1. Frame and, A glass panel placed inside the aforementioned frame, A mullion structure comprising a mullion positioned to the side of the glass panel and extending in the depth direction, The aforementioned mullion is, A mullion body having an indoor portion positioned on the indoor side of the glass panel, and a portion extending in the depth direction from the indoor portion through the gap between the glass panels to the outdoor side in the depth direction, An insulating member is provided which is located on the outdoor side of the glass panel and on the outside in the visible direction of the portion extending in the depth direction, A mullion structure comprising a metal outer metal frame member disposed on the outside of the aforementioned heat insulating member.
  2. The mullion structure according to claim 1, wherein the outer metal frame member is pressed against the interior side, thereby pressing the exterior surface of the glass panel against the exterior metal frame member and the interior portion to fix the end of the glass panel.
  3. The mullion structure according to claim 2, wherein the insulating member, together with the outer metal frame member, has a rigid resin member that pushes the exterior surface of the glass panel toward the interior, thereby fixing the end of the glass panel to the interior portion.
  4. The glass panel comprises two of the aforementioned glass panels, The two glass panels are arranged within the frame, adjacent to each other with a predetermined gap between them in the visible direction. The mullion structure according to claim 1 or 2, wherein the mullion is positioned to the side of the two glass panels and between the two glass panels.

Description

This disclosure relates to a mullion structure. Conventionally, a mullion structure is known in which a mullion is placed between two glass panels provided within a frame (see, for example, Patent Document 1). In the mullion structure described in Patent Document 1, a thermal insulation structure is achieved by a bridge structure in which a thermal insulation member is placed between the aluminum profile on the exterior side and the aluminum profile on the interior side of the mullion. Japanese Patent Application Publication No. 8-68264 This is a perspective view of the door/window of the first embodiment, seen from the outside.This is a cross-sectional view taken along line A-A in Figure 1.This is a cross-sectional view taken along line B-B in Figure 1, which is a transverse cross-sectional view of the mullion structure of the first embodiment.This is a cross-sectional view of the mullion structure of the second embodiment, which corresponds to the cross-sectional view taken along line B-B in Figure 1 of the first embodiment. The embodiments of this disclosure will now be described in detail with reference to the drawings. The first embodiment of the joinery 1 will be described. In this specification, "face direction" refers to the surface direction of the glass panel 4 in the joinery 1 fitted into an opening formed in the wall of a building, and "depth direction" refers to the thickness direction (i.e., depth direction) of the surface material. The "depth direction" is also the interior-exterior direction. "Face surface" refers to the exterior and interior surfaces of the joinery 1, respectively, and "depth surface" refers to the surface of the joinery 1 extending in the interior-exterior direction. In the drawings, the exterior side of the joinery 1 is referred to as exterior side X1, and the interior side of the joinery 1 is referred to as interior side X2. As shown in Figure 1, the window fixture 1 is composed of a series of windows and comprises a frame 2 attached to an opening in the building structure (not shown), multiple mullions 3 that divide the frame 2 into multiple areas in the left-right direction, and multiple glass panels 4 positioned between the frame 2 and the mullions 3. The frame 2 is constructed by framing an upper frame 21, a lower frame 22, and left and right vertical frames (not shown) in a rectangular shape. As shown in Figure 1, the multiple mullions 3 are arranged within the frame 2 and extend vertically. The multiple mullions 3 are positioned at intervals along the horizontal direction of the frame 2, dividing the frame 2 into multiple horizontal regions. Within the frame 2, a glass panel 4 is placed inside the area enclosed by the frame 2 and the mullions 3, thereby forming multiple fixed window sections 40. These fixed window sections 40 are non-opening and non-closable windows. The mullion structure 30 of mullion 3 will now be explained. In the mullion structure 30 shown in Figure 3, the side of the mullion 3 facing the center line C is referred to as the "inside in the left-right direction," and the side of the mullion 3 moving away from the center line C in the left-right direction is referred to as the "outside in the left-right direction." As shown in Figure 1, the mullion structure 30 comprises a frame 2, two glass panels 4 arranged adjacent to each other within the frame 2 at a predetermined distance in the left-right direction (lateral direction) of the visible surface, and a mullion 3 positioned between the two glass panels 4 on the left-right side and extending vertically. As shown in Figures 2 and 3, the glass panel 4 is a double-glazed panel in which a glass plate 41 on the indoor side X2 and a glass plate 42 on the outdoor side X1 are arranged with a predetermined gap between them by interposing a spacer 43. As shown in Figures 1 to 3, the mullion 3 is formed extending in the vertical direction. The upper end of the mullion 3 is connected to the upper frame 21 of the frame 2, and the lower end is connected to the lower frame 22 of the frame 2. As shown in Figures 2 and 3, the mullion 3 is formed extending in the depth direction and comprises a metal mullion body 31, a pair of heat-insulating resin structures 34 (heat-insulating members), a pair of metal outer metal frame members 35, and a metal outdoor-side cover portion 36. In the depth direction, the mullion 3 is formed to protrude outward from the glass panel 4. The mullion body 31, the pair of heat-insulating resin structures 34, the pair of outer metal frame members 35, and the outdoor cover portion 36 extend in the vertical direction. The mullion body 31 has an indoor portion 32 and an extension portion 33 in the depth direction. The metal mullion body 31, the pair of metal outer metal frame members 35, and the metal outdoor cover portion 36 are formed from extruded profiles of a metal material such as aluminum. As shown in Figure 3, the indoor portion 32 is positioned on the indoor side X2 of the two glass
