In Patent Literature 1, the outside of the panel holding frame corresponding to the glass core is fixed to the surface using rivets, and the inside of the panel is fixed to the surface using screws.

JP 2015-140533 A

  A fixing member such as a rivet or a screw for holding the glass core material may be a design constraint. In this regard, the structure disclosed in Patent Literature 1 arranges picture frames on both the outside and the inside of the room so that rivets, screws, and the like are not visible from the outside. However, in the structure of Patent Literature 1, work for fixing a fixing member such as a rivet or a screw is required on both sides (indoor and outside) of the door body, and a step of attaching a cover such as a frame to both sides of the door body also occurs. .

  There is a case where a cover such as a frame is not necessary for the function or design on one side surface of the door body (for example, the indoor side surface). Therefore, it is conceivable to mechanically fix only one side of the door body with rivets or screws, but there is a possibility that the surface material on the side not fixed by the fixing member is likely to be warped due to fire or the like.

  An object of the present invention is to provide a door body which can appropriately fill gaps by a heated foam material even when the surface material is warped due to a fire or the like and which can achieve both improvement in fire protection and design.

  The present invention relates to a door (for example, a door 10 to be described later) that is openably and closably attached to a frame (for example, a frame 2 to be described later), and an opening for a window (for example, an opening 21 to be described later). Is formed, one side surface material (for example, an outdoor surface material 20 described later) disposed on one side, and an opening for a window (for example, an opening 31 described later) are formed, and disposed on the other side. Other surface material (for example, an outdoor surface material 20 described later), and a glass surface material (for example, described later) disposed between the one surface material and the other surface material at a position corresponding to the opening. Glass surface material 60), a glass core material surrounding the glass surface material between the one-side surface material and the other-side surface material (for example, a glass core material 70 described later), the one-side surface material, and the A one-side heated foam material (for example, an outdoor heated foam material 120 described later) disposed between glass core materials, And a second-side heated foam material (for example, an indoor-side heated foam material 130 described later) disposed between the surface material and the glass core material, wherein one side surface of the glass core material is the one-side surface material. And the other side surface is fixed to the inner surface of the other side surface material by an adhesive, and the foam amount of the other side heated foam material is the same as that of the one side. The present invention relates to a door configured to be larger than the foaming amount of a side heating foam material.

  The door body includes a cover (for example, a molding 11 described later) that covers a portion of the one side surface material to which the fixing member is fixed, and a buffer disposed at least between the other side surface material and the glass surface material. (For example, Norseal 82 described later).

  ADVANTAGE OF THE INVENTION According to the door body of this invention, even if the surface material warps due to a fire or the like, it is possible to achieve both fire prevention and design improvement in which the gap can be properly filled with the heated foam material.

  Hereinafter, a fitting 1 provided inside a frame opening formed in a building and provided with a door body 10 that can be opened and closed will be described as an embodiment of the present invention.

  FIG. 1 is a view of a fitting 1 provided with a door body 10 according to the present embodiment as viewed from the outdoor side. As shown in FIG. 1, the fitting 1 includes a frame 2 fixed to the building side, and a door 10 attached to the frame 2 so as to be openable and closable.

  The frame 2 is framed in a rectangular shape by an upper frame 3 and a lower frame 4 as horizontal frames, a vertical frame 5 on a hanging side, and a vertical frame 6 on a door side.

  The door body 10 is a hinged door that is suspended inside the frame body 2 via a hinge 96 fixed to the vertical frame 5 on the hanging side.

  An upper cylinder lock 92, a handle 93, and a lower cylinder lock 94 are arranged on the door tip side of the door body 10 in order from the top. Further, a post 85 is disposed slightly below the center of the door body 10.

  The outdoor-side surface material (one-side surface material) 20 of the door body 10 is made of a steel plate, and an opening 21 for the window 50 is formed. The molding 11 is attached to the left and right sides of the window 50 of the outdoor facing material 20. In the present embodiment, the mall 11 is provided with a pair of vertically elongated members extending from the upper end to the lower end of the outdoor surface member 20.

  FIG. 2 is an enlarged view of the window 50 of the door body 10 of the present embodiment and its surroundings as viewed from the indoor side. As shown in FIG. 2, the indoor-side surface material (other-side surface material) 30 of the door body 10 is also made of a steel plate, and has an opening 31 for forming the window 50. The cover such as the mall 11 is not attached to the indoor side surface material 30 of the present embodiment.

  Next, a detailed configuration of the window 50 will be described. FIG. 3 is a cross-sectional view showing the window 50 of the door body 10 of the present embodiment and its surroundings. FIG. 4 is a longitudinal sectional view showing the window 50 of the door body 10 of the present embodiment and its surroundings.

  As shown in FIG. 3 and FIG. 4, the window 50 mainly includes a glass face material 60 and a glass core material 70 arranged so as to surround four circumferences of the glass face material 60.

  First, the glass face material 60 will be described. The glass surface material 60 is a light transmitting portion that forms a lighting window. In the present embodiment, the glass surface material 60 is a so-called double glazing.

  A nor seal 82, a bead 81, an outdoor heating foam material 120, and a waterproof material 80 are provided on the inner surface of the outdoor surface material 20 as a configuration for fixing the glass surface material 60. The nor seal 82, the bead 81, the outdoor heating foam material 120, and the waterproof material 80 are all mounted in a rectangular frame shape.

  A nor seal 82, a bead 81, and a heated indoor foam material 130 are provided on the inner surface of the interior surface material 30 as a configuration for fixing the glass surface material 60. The nor seal 82, the bead 81, and the indoor heating foam 130 are all mounted in a rectangular frame shape.

  The outdoor outer seals 82 are attached to the four sides of the opening 21 on the inner surface of the outdoor surface material 20. Similarly, the indoor side nor seal 82 is attached to the four sides of the opening 31 on the inner side surface of the indoor side surface member 30. Both the indoor side and outdoor side nor seals 82 are made of a material having flexibility, absorb variations in glass shape and glass pressure, and cause distortion in the outdoor side surface material 20 and the indoor side surface material 30. It functions as a cushioning material to prevent such a situation.

  The outdoor-side bead 81 is attached to the four seals of the opening 21 on the inner side surface of the outdoor-side surface member 20 so that a part (outside) of the bead overlaps with the nor seal 82. Similarly, the exterior bead 81 is affixed such that a part (outside) of the bead 81 overlaps the four seals of the opening 21 on the inner surface of the exterior surface material 20 so as to partially overlap the nor seal 82.

  The outdoor-side heated foam material 120 is disposed on four sides so as to surround the outer surface of the nor seal 82 on the outdoor side. In the present embodiment, the outdoor-side heated foam material 120 and the outdoor-side nor seal 82 have a positional relationship in which their end faces are in contact with each other, and their thicknesses are also substantially equal.

  The water blocking material 80 is arranged between the outdoor surface material 20 and the glass face material 60. The water blocking material 80 of the present embodiment is attached to the four sides of the opening 21 on the inner side surface of the outdoor surface member 20. The outdoor bead 81 is disposed adjacent to the outer surface of the bead 81, so that the outdoor surface is in contact with the outdoor heated foam 120 and the nor seal 82. The water blocking material 80 prevents rainwater or the like from entering from the opening 21 of the outdoor surface material 20.

  The indoor-side heated foam material 130 is arranged on four sides so as to surround the outer surface of the indoor-side nor seal 82. In the present embodiment, the indoor-side heated foam material 130 and the indoor-side nor seal 82 are in a positional relationship where the end faces are in contact with each other, and their thicknesses are also substantially equal. Since the water-stopping material 80 is not disposed on the indoor side, the outdoor-side surface of the indoor-side heated foam material 130 is located at a position facing the glass surface material 60.

  Next, the glass core material 70 will be described. The glass core member 70 is formed in a rectangular frame shape, and is arranged between the outdoor side surface member 20 and the indoor side surface member 30 so as to surround the end surface of the glass surface member 60.

  On the inner peripheral surface of the glass core material 70, a tape-like heated foam material 71 is arranged. The heated foam 71 is bonded and fixed over four sides of the inner peripheral surface of the glass core 70. In this embodiment, the heating foam 71 is also fixed to the glass core 70 by the setting block 72 having a substantially U-shaped cross section.

  A plurality of setting blocks 72 are arranged at intervals on the inner peripheral surface of the glass core material 70, and are fixed so that the heated foam material 71 is suppressed in the groove portions. In the present embodiment, two setting blocks 72 are arranged on the left and right inner surfaces extending vertically and two on the lower inner surface extending horizontally.

  The glass core 70 is formed in a flange shape on both the outside and the inside of the room, and a double-sided tape (not shown) is attached to this portion. That is, in the glass core material 70, each of the outdoor-side surface material 20 and the indoor-side surface material 30 is bonded and fixed by the adhesive of the double-sided tape.

  The glass core material 70 has its outdoor surface fixed by a rivet 200 as a fixing member. The positions where the rivets 200 are driven are on both sides in the left-right direction of the glass core material 70 and are set to positions that are hidden by the molding 11. In the present embodiment, the plurality of rivets 200 are driven so as to penetrate the outdoor surface material 20 according to the position of the outdoor end surface of the glass core material 70, and the glass core material 70 is solidified inside the door body 10. You.

  As described above, the outside surface of the glass core 70 is mechanically fixed by the rivet 200, and the inside surface is adhesively fixed. The method of fixing the glass core 70 on the outside and the inside of the room is different. Is different. The position where the rivet 200 is driven is hidden inside the mounting position of the molding 11, so that the rivet 200 cannot be visually recognized from the outside when the molding 11 is attached (see FIG. 1).

  Next, the relationship between the foaming amounts of the outdoor heating foam 120 and the indoor heating foam 130 will be described. The outdoor heating foam material 120 and the indoor heating foam material 130 are made of an epoxy resin, polyvinyl chloride (PVC), or the like. In the present embodiment, the outdoor heating foam 120 and the indoor heating foam 130 have the same expansion ratio, and the foaming amount is adjusted according to the size.

  The outdoor-side heated foam material 120 and the indoor-side heated foam material 130 have substantially the same thickness, and the amount of foaming is adjusted according to the area of the surface facing the indoor side or the outdoor side.

  More specifically, as shown in FIG. 3, the horizontal length W2 of the indoor heating foam 130 is greater than the horizontal length W1 of the outdoor heating foam 120. In addition, as shown in FIG. 4, the vertical length h2 of the indoor heating foam 130 is longer than the vertical length h1 of the outdoor heating foam 120. That is, by setting the area of the indoor-side heated foam material 130 to be larger than the area of the surface of the outdoor-side heated foam material 120 facing the inside and outside, the amount of foaming on the indoor side is set to be large.

According to the embodiment described above, the following effects can be obtained.
The door body 10 has an opening 21 for a window, an outdoor surface material 20 disposed on one side (outdoor), and an opening 31 for a window, and disposed on the other side (indoor). Outdoor surface material 20, a glass surface material 60 disposed at a position corresponding to the openings 21 and 31 between the outdoor surface material 20 and the indoor surface material 30, an outdoor surface material 20 and the indoor surface A glass core material 70 surrounding the glass face material between the surface materials 30, an outdoor heating foam material 120 disposed between the outdoor surface material 20 and the glass core material 70, an indoor surface material 30 and the glass core material 70, a room-side heated foam material 130 disposed between the two. The glass core member 70 has its outdoor surface fixed by a rivet 200 penetrating the outdoor surface material 20 and its indoor surface fixed to the inner surface of the indoor surface material 30 by an adhesive of a double-sided tape. . The indoor heating foam 130 has a foaming amount larger than that of the outdoor heating foam 120.

Accordingly, while the glass core 70 is largely supported by the rivet 200 on the outside of the room, the glass core 70 is stably held inside the door body 10 by adhesive fixing on the indoor side, and In this case, the rivet 200 does not appear on the outdoor surface material 20, so that the design can be freely performed without any restrictions.
Further, even if the indoor side surface material 30 to which the rivet 200 is not fixed is warped due to a fire, the gap generated due to the warpage can be sufficiently filled by the indoor side heated foam material 130 having a larger foaming amount than the outdoor side.
Further, since the mechanical fixing using the rivet 200 is performed only on one side, the number of times of performing the rivet fixing is reduced, and the step of attaching the molding or the frame on the indoor side can be omitted, and the productivity is improved.

  The door body 10 of the present embodiment includes a molding 11 that covers a place where the rivet 200 is fixed on the outdoor side surface member 20, and a nor seal 82 disposed at least between the indoor side surface member 30 and the glass surface member 60. .

  Thus, the rivet 200 is hidden by the molding 11 on the outdoor side, and a design in which the rivet 200 does not appear on the indoor side can be realized, and the glass pressure received by the interior surface material 30 can be received by the nor seal 82. Can be effectively prevented from being distorted in the indoor-side surface material 30 to which no is attached.

  As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited to the above-described embodiments, and can be appropriately changed.

  In the above-described embodiment, the adjustment of the foaming amount of the outdoor-side heated foam material 120 and the indoor-side heated foam material 130 is performed by differentiating the area (size). However, the adjustment is not limited to this method. An appropriate method can be adopted. For example, the amount of foaming can be adjusted by changing the length in the horizontal direction or the length in the vertical direction.

  Further, the amount of foaming can be adjusted by making the materials of the outdoor-side heated foam material 120 and the indoor-side heated foam material 130 different in expansion ratio. Moreover, the foaming amount may be adjusted by stacking heat-foamed materials having the same shape in the thickness direction. Further, the foaming amount may be adjusted by combining these methods.

  In the above embodiment, the glass core 70 is configured such that the outdoor side is fixed by the rivet 200 as a fixing member and the indoor side is bonded and fixed, but the fixing method can be appropriately changed depending on the layout and design. For example, a configuration may be adopted in which the inside of the glass core material 70 is fixed with rivets 200 and the outside of the glass core is bonded and fixed.

  In the above-described embodiment, the rivet 200 is used as a fixing member. However, other types of mechanical fixing such as screws, screws, nails, and the like can be used as the fixing member.
