An embodiment of the frame will be described with reference to FIGS. 1 to 4. In this embodiment, a frame of a partition plate provided in an apartment house such as a condominium will be described as an example.
As shown in FIG. 1, the partition plate P installed on the balcony B of the condominium has a frame body 10. The frame body 10 is composed of a pair of left and right vertical frames 11, a pair of upper and lower horizontal frames 12, and an intermediate frame 13 arranged between the pair of horizontal frames 12. The frames 11, 12, and 13 are formed by, for example, extruding an aluminum alloy material. In the frame body 10, the plate members 20 are supported by the frames 11, 12, and 13 in a vertically arranged state. The plate material 20 includes a first plate material 21 arranged above and a second plate material 22 arranged below. The plate material 20 is, for example, a nonflammable caucal plate or a flexible plate. In the present embodiment, the thickness of the second plate material 22 (for example, 4 mm) is formed thinner than the thickness of the first plate material 21 (for example, 5 mm), and the second plate material 22 is formed more than the first plate material 21. It is configured to be easy to break through. The partition plate P is fixed to the wall surface of the balcony B via the fixing metal fittings 30 attached to the pair of vertical frames 11. In the following, the thickness direction of the plate material 20 is simply referred to as the thickness direction.

As shown in FIG. 2, the vertical frame 11 includes a first main body portion 40 having a closed cross-sectional structure and a pair of support walls 45 formed in a shape protruding from the first main body portion 40 and arranged to face each other. have. The portion of the first main body 40 to which the pair of support walls 45 are connected is referred to as a connecting wall 41.

The pair of support walls 45 face each other in the thickness direction (vertical direction in FIG. 2). The pair of support walls 45 includes a pair of first support portions 46 constituting the opening 50, and a second support portion 47 located between the first support portion 46 and the first main body portion 40. The first support portion 46 is composed of an inlet end portion 46A constituting an opening and a curved portion 46B connected to the inlet end portion 46A. The inlet end portion 46A has a shape in which the distance between the inlet ends 46A is wider toward the tip side (left side in FIG. 2). The curved portion 46B has a substantially arc shape curved so that the distance between the central portions is widest. In the first support portion 46, the distance D1 between the inlet end portions 46A is the narrowest. In the pair of first support portions 46, each of the inlet end portion 46A and the curved portion 46B is formed in a curved shape so as to change the distance between the entrance end portion 46A and the curved portion 46B in the thickness direction.

The second support portion 47 includes a pressing portion 47A connected to the curved portion 46B and a fixing portion 47B connected to the pressing portion 47A. The fixed portion 47B is connected to the first main body portion 40 and extends in parallel with each other. The pressing portions 47A approach each other once from the proximal end side connected to the fixed portion 47B to the distal end side connected to the curved portion 46B, but then expand so as to be separated from each other. As described above, the holding portion 47A has a curved shape in which the central portion is constricted. That is, the second support portion 47 is formed in a curved shape so that the distance between the holding portion 47A and the facing support portion changes. In the second support portion 47, the gap D2 of the constricted portion of the holding portion 47A is the narrowest, and this gap D2 is narrower than the gap D1 of the inlet end portion 46A of the first support portion 46 (D1> D2). .. Therefore, the pair of second support portions 47 support the plate material 20 at intervals narrower than the interval at which the pair of first support portions 46 support the plate material 20.

That is, when the thin second plate material 22 is inserted inward through the openings 50 of the pair of support walls 45, it passes between the first support portions 46 and reaches between the second support portions 47. To reach. Therefore, the second plate member 22 is sandwiched and supported in the thickness direction by the pressing portion 47A of the second supporting portion 47. In the state where the second support portion 47 sandwiches the second plate material 22 in the thickness direction, the pressing portion 47A and the second plate material 22 may be in contact with each other, or the pressing portion 47A and the second plate material 22 may be in contact with each other. A predetermined clearance may be provided between them.

Further, as shown in FIG. 3, since the first plate material 21 is thicker than the second plate material 22, the first support portion is inserted into the back side through the openings 50 of the pair of support walls 45. It is in a state of hitting the curved portion 46B of the 46, and does not reach between the second support portions 47. Therefore, the first plate member 21 is sandwiched and supported in the thickness direction by the inlet end portion 46A of the first support portion 46. In the state where the first support portion 46 sandwiches the first plate material 21 in the thickness direction, the inlet end portion 46A and the first plate material 21 may be in contact with each other, or the inlet end portion 46A and the first plate material 21 may be in contact with each other. A predetermined clearance may be provided between the and. The shape of the curved portion 46B is preset so as to have an insertion amount that can appropriately support the first plate material 21 in the frame body 10 when the first plate material 21 is inserted until it is abutted against the curved portion 46B. There is.

Since the pair of horizontal frames 12 have the same configuration as the vertical frame 11 described above, detailed description thereof will be omitted, and then the configuration of the intermediate frame 13 will be described.
As shown in FIG. 4, the intermediate frame 13 has a second main body portion 60 having a closed cross-sectional structure and a pair of support walls 45 formed in a shape protruding from the second main body portion 60 and arranged to face each other. .. The pair of support walls 45 includes a pair of upper support walls 45A having a shape protruding upward from the second main body portion 60, and a pair of lower support walls 45B having a shape protruding downward from the second main body portion 60. The configuration of the upper support wall 45A and the lower support wall 45B is the same as the configuration of the pair of support walls 45 of the vertical frame 11 described above. Therefore, the same components as those of the vertical frame 11 are designated by the same reference numerals, and the description thereof will be omitted. The pair of upper support walls 45A support the lower peripheral edge portion of the first plate member 21 by the first support portion 46 facing in the thickness direction (left-right direction in FIG. 4). Further, the pair of lower support walls 45B support the upper peripheral edge portion of the second plate member 22 by the second support portion 47 facing in the thickness direction.

The intermediate frame 13 is also provided with a screw fastening wall 61 connected to the second main body 60. The screw fastening wall 61 is provided along a direction (horizontal direction in FIG. 4) orthogonal to the arrangement direction (vertical direction in FIG. 4) between the upper support wall 45A and the lower support wall 45B. Further, the intermediate frame 13 is also provided with a peripheral side wall 62 connecting the tip of the upper support wall 45A and the tip of the lower support wall 45B. In the intermediate frame 13, a closed cross-sectional structure is formed by the main body portion, the upper support wall 45A, the peripheral side wall 62, the lower support wall 45B, and the screw fastening wall 61. As a result, in the intermediate frame 13, the rigidity of the upper support wall 45A and the lower support wall 45B is increased.

Next, the operation and effect of this embodiment will be described.
(1) In the present embodiment, the pair of support walls 45 of the frame body 10 are provided with a first support portion 46 and a second support portion 47 having a narrower interval than the first support wall. Therefore, it is possible to set the plate thickness of the plate material that can be supported by the support wall 45 of the frame body 10 in two stages. Therefore, the plate materials 20 having different thicknesses such as the first plate material 21 and the second plate material 22 can be supported by one frame body 10, and the versatility can be enhanced. In addition, as the structure of the conventional frame, the space between the pair of support walls is set large with a margin, and the difference in the thickness of the plate is absorbed by the packing embedded in the gap between the plate and the frame. The configuration is practical. According to the present embodiment, since it is possible to cope with the difference in the plate thickness of the plate material 20 without providing the packing, it is possible to contribute to the reduction of the number of parts as compared with the conventional frame body.

(2) In the present embodiment, each of the support portions of the first support portion 46 and the second support portion 47 is formed in a curved shape so that the distance between the first support portion 46 and the second support portion 47 changes. Therefore, the first support portion 46 and the second support portion 47 that support the plate material 20 tend to bend in the thickness direction. Therefore, when the plate material 20 is assembled to each of the support portions 46 and 47, it is possible to absorb the dimensional tolerance in the thickness of the plate material 20 and the thickness of the coating film formed on the surface of the plate material 20. Therefore, it can contribute to further improvement of versatility of the frame body 10.

(3) In the present embodiment, the inlet end portion 46A of the first support portion 46 constituting the opening 50 through which the plate material 20 is inserted and the holding portion 47A serving as the entrance of the second support portion 47 are expanded toward the tip side. Formed into a shape. Therefore, when the plate member 20 is inserted, it is easy to be guided between the first support portions 46 and between the second support portions 47. Therefore, it is possible to improve the assembling property of the plate material 20 to the pair of support walls 45.

This embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
-In the above embodiment, the frame body 10 may have a core material for reinforcement inside the first main body portion 40. For example, as shown in FIG. 5, a core material 70 having the same length as the vertical frame 11 is inserted and arranged inside the first main body portion 40 of the vertical frame 11. The core material 70 includes a pair of engaging portions 71 having substantially the same outer shape as the inner peripheral shape of a part of the first main body portion 40, and a connecting portion 72 connecting the pair of engaging portions 71. It is composed of a pair of lining portions 73 that protrude from the connecting portion 72 and come into contact with the inner peripheral surface of the connecting wall 41 of the first main body portion 40. The core material 70 may be made of the same material as the first main body 40 or a different material. In this way, by providing the core material 70 for reinforcement inside the main body portion of the frame body 10, the rigidity of the main body portion can be improved. Therefore, it is not necessary to change the outer shape of the frame 10 in order to secure the rigidity that can withstand the influence of wind pressure or the like in the partition plate P installed on the upper floors of the condominium, and the frame 10 is also used in high-rise buildings. A sense of unity can be ensured.

The cross-sectional shape of the core material 70 can be changed as appropriate. That is, one of the engaging portion 71 and the backing portion 73 may be omitted. Further, the core material 70 is not limited to the vertical frame 11, but may be provided in the horizontal frame 12 or the intermediate frame 13. When provided in the intermediate frame 13, a closed cross-sectional structure composed of a second main body 60, an upper support wall 45A, a peripheral side wall 62, a lower support wall 45B, and a screw fastening wall 61, not limited to the inside of the second main body 60. It is also possible to install it inside.

The shape of the pair of support walls 45 is not limited to that of the above embodiment. For example, the distance D1 of the inlet end portion 46A may be narrower than the distance D2 of the holding portion 47A depending on the amount of elastic deformation when the plate material 20 is assembled to the first support portion 46. Even with such a configuration, it is possible to realize a configuration in which the pair of second support portions 47 support the plate material 20 at intervals narrower than the interval at which the pair of first support portions 46 support the plate material 20. Further, the inlet end portion 46A and the pressing portion 47A may not be formed in a shape that expands toward the tip side, or the fixing portion 47B may be formed in a curved shape.

Further, as another configuration of the pair of support walls, for example, the configuration shown in FIG. 6 can be adopted. That is, in the pair of support walls 85, the pair of first support portions 86 constituting the opening 50 are configured to extend in parallel. Further, the pair of second support portions 87 is composed of a fixed portion 87B extending in parallel from the first main body portion 40 and a bent portion 87A extending from the fixed portion 87B in a direction orthogonal to the extending direction of the fixed portion 87B. The distance between the fixed portions 87B is made narrower than the distance between the first support portions 86. According to such a configuration, the pair of support walls 85 have a shape extending in a straight line instead of a curved shape, and the second support portion 87 is formed in a stepped shape so as to have a narrower interval than the first support portion 86. To. Even with such a configuration, the pair of second support portions 87 can support the plate material 20 at intervals narrower than the interval at which the pair of first support portions 86 support the plate material 20.

-The main body of the frame 10 does not necessarily have to have a closed cross-sectional structure. For example, the main body may be composed of only a connecting wall 41 connecting a pair of support walls 45.
-The material constituting the frame body 10 may be a metal other than an aluminum alloy or a resin. Further, the frame body 10 may be made of a material different from metal or resin. Further, the manufacturing method of the frame body 10 is not limited to the extrusion molding, and a press molding, a molding method using a 3D printer, or the like can be appropriately adopted.

In the above embodiment, a configuration in which a pair of support walls 45 having a first support portion 46 and a second support portion 47 are provided on all of the pair of vertical frames 11, the pair of horizontal frames 12, and the intermediate frame 13 is exemplified. However, it goes without saying that the same operation and effect as in (1) above can be obtained if the pair of support walls 45 described above is provided in at least a part of each frame constituting the frame body 10.

-It is also possible to provide a plurality of intermediate frames 13 in the frame body 10. Further, in the frame body 10, at least one of a pair of vertical frames 11, a pair of horizontal frames 12, and an intermediate frame 13 may be omitted.

In the above embodiment, the frame body 10 that supports the first plate material 21 and the second plate material 22 having different thicknesses as the plate material 20 is exemplified. The frame is not limited to supporting plate materials having different thicknesses, and may be configured to support plate materials having the same thickness. For example, in the frame body 10, it is also possible to adopt a configuration in which two first plate members 21 are supported side by side. Further, the frame body may be configured to support one plate material or three or more plate materials.
