Summary of the Invention

Problems to be Solved by the Invention

[0004] For fittings as described above, in order to improve their design properties, slimming of the frame member is desired. However, when the frame member is slimmed, the strength of the member decreases, and there is a possibility that the support strength of the face material becomes insufficient. In addition, such insufficient strength can occur not only when the frame member is slimmed, but also, for example, in fittings that receive strong wind pressure on high floors and the like.

[Modes for carrying out the invention]

[0010] Hereinafter, preferred embodiments of the surface material support structure and surface material support method according to the present invention will be described in detail with reference to the attached drawings.

[0011] As shown in Figure 1, the panel support structure 10 according to this embodiment can be applied to, for example, a door or window that separates the interior and exterior of a house or shop. The door or window 12 comprises an opening frame 14 fixed to an opening in the building frame, and an interior sash 16 and an exterior sash 17 that are slidably supported inside the opening frame 14. In this embodiment, an example is given of applying the panel support structure 10 to a sliding window door or window 12 in which the sashes 16 and 17 are slidably supported from left to right inside the opening frame 14. In addition to sliding windows, other examples of applications for the panel support structure 10 include single-hung windows, fixed windows, double-hung windows, casement windows and other rotating windows, doors, and the like.

[0012] First, let me explain the overall structure of the door / window 12.

[0013] The opening frame 14 is constructed by framing the upper frame 14a, the lower frame 14b, and the left and right vertical frames 14c and 14d around the perimeter, forming a rectangular opening on the inside.

[0014] In this application, the prospective direction refers to the indoor-outdoor direction of the fitting 12, that is, the direction from the indoor side to the outdoor side or the reverse direction (the direction indicated by the arrow Z in the figure), and the prospective plane refers to the plane extending along the prospective direction. The finding direction is the direction orthogonal to the prospective direction. In the case of a vertically long vertical frame 14c or the like, it refers to the left-right direction orthogonal to its longitudinal direction (the direction indicated by the arrow X in the figure), and in the case of a horizontally long upper frame 14a or the like, it refers to the up-down direction orthogonal to its longitudinal direction (the direction indicated by the arrow Y in the figure). The finding plane refers to the plane along the finding direction. The inner peripheral side refers to the inner part of the opening frame 14 which is a frame-shaped member. The outer peripheral side refers to the outer part of the opening frame 14 which is a frame-shaped member.

[0015] The frames 14a to 14d can be formed of extruded members of a metal material such as aluminum or extruded members of a resin material such as vinyl chloride resin (PVC). The frames 14a to 14d may have a composite structure in which the surface of the metal material is covered with a resin material. The outer peripheral sides of the frames 14a to 14d of the opening frame 14 are fixed to the building body with fixtures such as screws or nails.

[0016] The inner shutter 16 includes a face material 20, an upper frame 22a, a lower frame 22b, a door end frame 22c, and a calling frame 22d that surround the four circumferences of the face material 20.

[0017] The face material 20 is, for example, a two-layer laminated glass in which a pair of plate glasses 20a and 20b face each other with a spacer part 20c interposed therebetween (see FIG. 2). The face material 20 may be single-layer or three or more layers. The spacer part 20c has, for example, a configuration in which the outer peripheral side of a spacer enclosing a desiccant is sealed with a sealing agent. The face material 20 can also be made of materials other than glass, such as punched metal, resin panel, or wooden panel.

[0018] Frames 22a to 22d can be formed from extruded metal profiles or extruded resin profiles such as polyvinyl chloride (PVC). Frames 22a to 22d may also be composite structures in which the surface of a metal material is covered with a resin material. As shown in Figure 2, the meeting frame 22d has an opening groove 24 that opens toward the inner circumference. The opening groove 24 is the part into which the edge 26 of the facing material 20 is inserted and held. The other frames 22a to 22c also have opening grooves similar to the opening groove 24, into which the edge of the facing material 20 is inserted and held.

[0019] The outer sliding door 17 comprises a facing material 28 and an upper frame 30a, a lower frame 30b, a door edge frame 30c, and a meeting frame 30d that surround the four sides of the facing material 28. The outer sliding door 17 may have the same or similar configuration as the inner sliding door 16 described above, so a detailed explanation is omitted. The sliding doors 16 and 17 can slide within the opening frame 14 by providing, for example, guide grooves on the outer circumference of the upper frames 22a and 30a for sliding the guide rail on the upper frame 14a side, and door rollers on the outer circumference of the lower frames 22b and 30b.

[0020] Next, the panel support structure 10 will be described.

[0021] In this embodiment, the meeting stile 22d of the inner shoji screen 16 is used as an example of the frame material to which the panel support structure 10 is applied. The frame material to which the panel support structure 10 is applied may also be the meeting stile 30d of the outer shoji screen 17, or other stiles 22a-22c, 30a-30c. Below, as shown in Figure 2, the panel support structure 10 will be described using the meeting stile 22d of the inner shoji screen 16 as an example.

[0022] Prior to describing the panel support structure 10, a specific example of the configuration of the meeting stile 22d to which the panel support structure 10 is applied will be described. As shown in Figure 2, the meeting stile 22d has a bottom wall 32 and side walls 33, 34 that form an opening groove 24, and has a roughly U-shaped cross-section.

[0023] The bottom wall 32 is a wall portion that runs along the depth direction (indoor-outdoor direction) of the meeting stile 22d. The bottom wall 32 forms the bottom surface 24a of the opening groove 24. The side walls 33 and 34 are wall portions that run along the visibility direction of the meeting stile 22d. The side walls 33 and 34 are projections that protrude inward from both ends of the bottom wall 32 in the depth direction. The side wall 33 on the indoor side forms the indoor side surface 24b of the opening groove 24. The side wall 34 on the outdoor side forms the outdoor side surface 24c of the opening groove 24. One of the side walls 33 and 34 may be made of a trim strip.

[0024] Engaging pieces 33a and 34a are formed protruding from the tip of the side walls 33 and 34, respectively. The engaging pieces 33a and 34a are projections for attaching the bead material 40 and 41, which will be described later. The engaging pieces 33a and 34a are not shown in Figure 2(A), and the same applies to the right diagram in Figures 4(A) to (C) and Figure 7 to 12 (A).

[0025] Reference numeral 36 in Figure 2 indicates a smoke deflector. The smoke deflector 36 combines with a smoke deflector provided on the meeting stile 30d of the outer shoji screen 17, which faces the meeting stile 22d when the shoji screens 16 and 17 are fully closed. The smoke deflector 36 of the inner shoji screen 16 is provided on the exterior-facing surface of the meeting stile 22d. The smoke deflector of the outer shoji screen 17 is provided on the interior-facing surface of the meeting stile 30d.

[0026] As shown in Figure 2, the surface material support structure 10 of this embodiment may include bead materials 40, 41, bottom adhesive members 42, 43, side adhesive members 44, 45, and a solid member 46.

[0027] In Figures 2(A) and 2(B), adhesive members 42-45 are shown with hatching, while the cross-sectional hatching of the meeting stile 22d and bead members 40, 41 is omitted. In Figure 2(A), the illustration of side adhesive members 44, 45 is omitted. Figures 7-12 are illustrated in the same way as Figure 2.

[0028] The bead materials 40 and 41 are airtight materials called glazing beads or packing. The bead materials 40 and 41 are made of, for example, rubber or soft resin. The bead materials 40 and 41 are press-fitted between the face material 20 and the side walls 33 and 34, and support the edge portion 26 of the face material 20 within the opening groove 24. The indoor bead material 40 is sandwiched between the indoor surface 20d of the face material 20 and the inner surface (indoor side surface 24b) of the side wall 33. The outdoor bead material 41 is sandwiched between the outdoor surface 20e of the face material 20 and the inner surface (outdoor side surface 24c) of the side wall 34.

[0029] The adhesive members 42-45 can be formed from, for example, a sealant. In this embodiment, the adhesive members 42-45 use, for example, a moisture-curing, one-component sealant. The adhesive members 42-45 can also use a reaction-curing, two-component sealant. However, as will be described later, the support strength of the surface material 20 in the surface material support structure 10 of this embodiment is high due to the support action of the bead materials 40, 41 and the adhesive members 42-45. Therefore, in this embodiment, the adhesive members 42-45 can use a one-component sealant, which is less adhesive in strength than a two-component sealant but is less expensive and easier to handle.

[0030] The bottom adhesive members 42 and 43 are filled between the edge surface 26a of the surface material 20 and the bottom surface 24a of the opening groove 24, and bond the two together. One bottom adhesive member 42 supports the area of ​​the edge surface 26a closer to the indoor side (first range A1). The other bottom adhesive member 43 supports the area of ​​the edge surface 26a closer to the outdoor side (second range A2). The bottom adhesive members 42 and 43 are arranged point-symmetrically to each other in a plan view of the bottom surface 24a and are arranged alternately in a staggered pattern along the longitudinal direction of the meeting stile 22d.

[0031] Here, the first range A1 can be rephrased as the range that includes the portion of the edge surface 26a that is on the indoor side of the center in the indoor-outdoor direction, and in the configuration example shown in Figure 2, this range is from near the center of the surface material 20 in the Z direction to the indoor side surface 20d. Similarly, the second range A2 can be rephrased as the range that includes the portion of the edge surface 26a that is on the outdoor side of the center in the indoor-outdoor direction, and in the configuration example shown in Figure 2, this range is from near the center of the surface material 20 in the Z direction to the outdoor side surface 20e.

[0032] The bottom adhesive member 42 on the interior side is positioned opposite the first range A1 of the edge surface 26a in a plan view of the bottom surface 24a shown in Figure 2(A). In other words, the bottom adhesive member 42 is positioned opposite the edge surface 26a of the interior side glass plate 20a. This allows the bottom adhesive member 42 to bond the glass plate 20a to the bottom surface 24a. The bottom adhesive member 43 on the exterior side is positioned opposite the second range A2 of the edge surface 26a in a plan view of the bottom surface 24a. In other words, the bottom adhesive member 43 is positioned opposite the edge surface 26a of the exterior side glass plate 20b. This allows the bottom adhesive member 43 to bond the glass plate 20b to the bottom surface 24a.

[0033] One side adhesive member 44 is filled between the indoor surface 20d of the facing material 20 and the indoor side surface 24b of the opening groove 24 on the outer circumference of the bead material 40, thereby bonding the two together. The other side adhesive member 45 is filled between the outdoor surface 20e of the facing material 20 and the outdoor side surface 24c of the opening groove 24 on the outer circumference of the bead material 41, thereby bonding the two together. The application range of the side adhesive members 44 and 45 in the Y direction is, for example, the total length of the application range of the bottom adhesive members 42 and 43 in the Y direction (see Figure 4(B)). As a result, a portion of the side adhesive member 44 is in contact with and integrated with the bottom adhesive member 42, and a portion of the side adhesive member 45 is in contact with and integrated with the bottom adhesive member 43.

[0034] The solid member 46 is fixed to the bottom surface 24a of the opening groove 24 and interposed between the bottom surface 24a and the edge surface 26a. The solid member 46 is, for example, a block-shaped part made of rubber or resin. The solid member 46 shown in Figure 2 uses a setting block commonly used to support surface materials. The solid member 46 is a guide component that allows for easy visual control of the application range of the adhesive members 42-45, and significantly improves the efficiency of the application work of the bottom adhesive members 42 and 43 in particular. The solid member 46 also has the function of reducing the amount of bottom adhesive members 42 and 43 used.

[0035] As shown in Figure 2(A), the solid member 46 may have a first portion 46a and a second portion 46b. The portions 46a and 46b are made of separate parts. In this embodiment, portions 46a and 46b are each made of the general-purpose setting blocks described above, thereby reducing the cost of parts. As shown in Figure 7, the portions 46a and 46b of the solid member 46 may be made of a single integrally molded part, as in the solid member 60.

[0036] The first part 46a is positioned to fill the area from near the center of the surface material 20 in the Z direction to the exterior side surface 24c in a plan view of the bottom surface 24a. The second part 46b is positioned to fill the area from near the center of the surface material 20 in the Z direction to the interior side surface 24b in a plan view. Parts 46a and 46b are positioned point-symmetrically in a plan view and are arranged in a staggered pattern along the longitudinal direction of the meeting stile 22d.

[0037] Thus, the solid member 46 has staggered portions 46a and 46b. For this reason, the surface material support structure 10 has non-placement portions 48a and 48b formed between the bottom surface 24a and the edge surface 26a in the installation range of the solid member 46 in the Y direction. The first non-placement portion 48a is the area adjacent to the indoor side of the first portion 46a and is located opposite the first range A1 of the edge surface 26a. The second non-placement portion 48b is the area adjacent to the outdoor side of the second portion 46b and is located opposite the second range A2 of the edge surface 26a. The first non-placement portion 48a is filled with bottom adhesive member 42. The second non-placement portion 48b is filled with bottom adhesive member 43.

[0038] Next, the method for supporting the facing material to construct the facing material support structure 10 will be explained with reference to Figures 3 to 6.

[0039] First, as shown in Figure 3, the solid member 46 is attached to the meeting stile 22d, which is the frame material to which the surface material support structure 10 is applied. The solid member 46 can be fixed to the bottom surface 24a of the opening groove 24 using an adhesive member 50. The adhesive member 50 can be the same or similar sealing material as adhesive members 42 to 45.

[0040] As shown in Figure 3(A), the adhesive member 50 is applied to the surface of the solid member 46 by manually squeezing it out from, for example, the tip nozzle 52a of the container tube 52. The adhesive member 50 may also be applied using an application tool such as a sealing gun. As shown in Figure 3(B), the solid member 46 is bonded to the bottom surface 24a with the side to which the adhesive member 50 has been applied. The solid member 46 is arranged in a staggered pattern with portions 46a and 46b as described above. The installation locations and number of solid members 46 along the entire length of the meeting stile 22d can be appropriately changed according to the strength required to support the surface material 20. In this embodiment, the boundaries of portions 46a and 46b are installed so as to be approximately at the center in the longitudinal direction of the meeting stile 22d (see also Figures 1 and 5).

[0041] Next, as shown in Figure 4, adhesive members 42-45 are applied to the bottom surface 24a and side surfaces 24b, 24c of the opening groove 24. The adhesive members 42-45 can also be applied from the tip nozzle 52a of the tube 52.

[0042] As shown in Figure 4(A), the bottom adhesive member 42 is applied to the first portion 46a and the adjacent first non-placed portion 48a, and the bottom adhesive member 43 is applied to the second portion 46b and the adjacent second non-placed portion 48b. The bottom adhesive members 42 and 43 are applied while visually confirming the solid member 46 and the non-placed portions 48a and 48b, so as to fill the non-placed portions 48a and 48b. This allows the bottom adhesive members 42 and 43 to be easily applied to the desired application area. At this time, the application thickness of the bottom adhesive members 42 and 43 is the same as or slightly thicker than the thickness of the solid member 46. This allows the application thickness of the bottom adhesive members 42 and 43 to be easily controlled to the thickness necessary for reliable adhesion between the bottom surface 24a and the edge surface 26a (see Figures 2(B) and 6).

[0043] As shown in Figure 4(B), it is preferable to apply the side adhesive members 44 and 45 after applying the bottom adhesive members 42 and 43. The side adhesive member 44 is applied linearly along the longitudinal direction (Y direction) of the indoor side surface 24b of the opening groove 24. The side adhesive member 45 is applied linearly along the longitudinal direction (Y direction) of the outdoor side surface 24c of the opening groove 24. The side adhesive members 44 and 45 are applied along the sides 24b and 24c while visually confirming the installation range of the solid member 46 in the Y direction. This makes it easy to apply the side adhesive members 44 and 45 to the desired application range.

[0044] In this process, it is preferable to apply a small amount of the side adhesive members 44 and 45 to areas where it is difficult to insert the tip nozzle 52a after inserting the surface material 20 into the opening groove 24. Specifically, the side adhesive members 44 and 45 should be applied to the parts hidden on the outer circumference side of the engaging pieces 33a and 34a on the sides 24b and 24c. In other words, the surface material support method of this embodiment involves performing the application process of the side adhesive members 44 and 45 in two stages. The application process shown in Figure 4(B) above corresponds to the first application process of the side adhesive members 44 and 45. Hereinafter, the side adhesive members 44 and 45 applied in the first application process may be referred to as the previous process side adhesive members 44a and 45a.

[0045] As shown in Figure 4(C), it is preferable to apply adhesive member 54 to the surface of the solid member 46 facing the edge surface 26a before or after the application process of adhesive members 42 to 45 shown in Figures 4(A) and 4(B). The adhesive member 54 is for bonding the solid member 46 to the edge surface 26a and increasing the support strength of the surface material 20. The same or similar sealing material as that used for adhesive members 42 to 45 can be used for adhesive member 54. The thickness of adhesive member 54 is thinner than that of bottom adhesive members 42 and 43 by the thickness of the solid member 46. Therefore, the adhesive member 54 can be applied to the surface of portions 46a and 46b, for example, in a meandering or wave-like shape, thereby reducing the amount of sealing material used.

[0046] Next, assemble the inner sliding door 16 as shown in Figure 5.

[0047] As shown in Figure 5(A), the upper frame 22a and lower frame 22b are assembled to the meeting frame 22d, which is equipped with adhesive members 42-45 and solid member 46. This makes the frames 22a, 22b, and 22d U-shaped. Next, the facing material 20 is inserted into the opening grooves of the upper frame 22a and lower frame 22b from the ends, and the edge portion 26 is inserted into the opening groove 24 of the meeting frame 22d. At this point, at least the edge surface 26a of the facing material 20 is bonded to the bottom surface 24a of the opening groove 24 by the bottom adhesive members 42 and 43. At this stage, the side adhesive members 44 and 45 consist only of the side adhesive members 44a and 45a from the previous step, and their coating thickness is thin (see Figures 4(B) and 4(C)). Therefore, although the surface 20d and 20e of the facing material 20 may be bonded to some extent to the side bonding members 44a and 45a of the previous process, the bonding strength is not sufficient.

[0048] As shown in Figure 5(B), the door frame 22c is assembled to the upper frame 22a and the lower frame 22b. As a result, the inner sliding door 16 is temporarily supported on all four sides of the facing material 20 by the rectangular frame-shaped frames 22a to 22d.

[0049] As shown in Figure 5(C), the bead materials 40 and 41 are pressed into the gap between the face material 20 and the side walls 33 and 34. The bead materials 40 and 41 are ring-shaped to match the frame shape of, for example, the frames 22a to 22d. Therefore, the bead materials 40 and 41 are pressed into each frame 22a to 22d as appropriate. This almost completes the assembly of the inner sash 16. At this time, it is preferable not to press the bead materials 40 and 41 into the parts where adhesive members 42 to 45 and solid members 46 are provided, but to leave some degree of flexure to form flexible portions 40a and 41a.

[0050] Next, as shown in Figure 6, a second coating process is performed on the side adhesive members 44 and 45. In Figure 6, the solid member 46 is not shown, and only the bottom adhesive members 42 and 43 are shown between the edge surface 26a and the bottom surface 24a. The lower diagram enclosed by the dashed line in Figure 6(A) is an enlarged view showing the cross-sectional shape of the part enclosed by the dashed line in the upper diagram.

[0051] As shown in Figure 6(A), the second coating step for the side adhesive members 44 and 45 is performed by inserting the tip nozzle 52a into the gap formed by the flexible portions 40a and 41a. If the flexible portions 40a and 41a are not formed in the press-fitting step of the bead material 40 and 41 shown in Figure 5(C), it is advisable to pull up a portion of the already pressed-fitted bead material 40 and 41 to form the flexible portions 40a and 41a before the second coating step.

[0052] The second application step of the side adhesive members 44 and 45 involves filling the gaps between the pre-process side adhesive members 44a and 45a applied in the first application step and the surfaces 20d and 20e of the facing material 20 with the side adhesive members 44 and 45. Hereinafter, the side adhesive members 44 and 45 applied in the second application step may also be referred to as the post-process side adhesive members 44b and 45b. The post-process side adhesive members 44b and 45b are applied in sufficient quantities to reliably fill the gaps between the pre-process side adhesive members 44a and 45a and the facing material 20. As a result, the pre-process side adhesive members 44a and 45a and the post-process side adhesive members 44b and 45b are integrated to form the side adhesive members 44 and 45.

[0053] Next, as shown in Figure 6(B), the flexible portions 40a and 41a of the bead materials 40 and 41 are pressed into the space between the surfaces 20d and 20e and the side walls 33 and 34 from the inner circumference side of the side adhesive members 44 and 45. As a result, the side adhesive members 44 and 45 are compressed by the bead materials 40 and 41, and securely bond the surfaces 20d and 20e of the facing material 20 to the sides 24b and 24c of the opening groove 24. Consequently, a facing material support structure 10 is formed in which the facing material 20 is firmly supported within the opening groove 24 by the bead materials 40 and 41 and the adhesive members 42 to 45.

[0054] As described above, the panel support structure 10 of this embodiment includes bead materials 40 and 41 sandwiched between the surfaces 20d and 20e of the panel material 20 and the side walls 33 and 34 of the opening groove 24 of the frame material (for example, the meeting stile 22d). Furthermore, the panel support structure 10 includes bottom adhesive members 42 and 43 filled between the edge surface 26a of the panel material 20 and the bottom surface 24a of the opening groove 24, and side adhesive members 44 and 45 filled on the outer circumference of the bead materials 40 and 41 between the surfaces 20d and 20e of the panel material 20 and the side surfaces 24b and 24c of the opening groove 24.

[0055] With this type of panel support structure 10, the edge 26 of the panel 20 is supported within the opening groove 24 together with the bead material 40, 41 using adhesive members 42-45 on three sides, thereby increasing the support strength of the panel 20. Therefore, the panel support structure 10 can firmly support the panel 20 even with frame materials such as the meeting stile 22d, which has a slimmed-down width and a reduced depth of the opening groove 24, as shown in Figure 2(B). The panel support structure 10 is also effective when applied to joinery that is subjected to high wind pressure.

[0056] In particular, the meeting stile 22d is not supported by the frames 14a to 14d of the opening frame 14, unlike the other stiles 22a to 22c, and is exposed independently on the inside of the opening frame 14 (see Figure 1). For this reason, the meeting stile 22d is particularly prone to bending and warping due to the slimming of its visible width and the effects of wind pressure, resulting in a problem where the support of the facing material 20 is less stable than that of the other stiles 22a to 22c. Therefore, it is preferable to provide the facing material support structure 10 at least on the meeting stile 22d (30d). In this way, the joinery 12 can increase the support strength of the facing material 20 as a whole while minimizing the increase in parts cost and labor cost due to the use of adhesive members 42 to 45 and solid members 46.

[0057] Thus, from the viewpoint of the support strength of the surface material 20 in the surface material support structure 10, the solid member 46 is not essential. However, by using the solid member 46 in the surface material support structure 10, the application range and amount of adhesive members 42-45 can be easily controlled by visual inspection. In other words, the surface material support structure 10 does not require the use of measuring instruments for applying adhesive members 42-45. As a result, the surface material support structure 10 improves work efficiency and also achieves cost reduction by optimizing the amount of adhesive members 42-45 used. Furthermore, in the surface material support structure 10, the solid member 46 is placed on the bottom surface 24a, and bottom adhesive members 42 and 43 are provided in the non-placement areas 48a and 48b, which are the gaps between the solid member 46. This further reduces the amount of bottom adhesive members 42 and 43 used. Moreover, the application thickness of the bottom adhesive members 42 and 43 can be easily controlled to be the same as or greater than the thickness of the solid member 46 by visually inspecting it. Therefore, the coating thickness of the bottom adhesive members 42 and 43 can be smoothly controlled to ensure sufficient adhesive strength, further improving and stabilizing the support strength of the surface material 20. In addition, variations in quality due to the operator performing the coating work of the adhesive members 42 to 45 can be suppressed.

[0058] Incidentally, the surface material 20 has a two-layer structure in which the thickness of a single sheet of glass 20a, 20b is thin (see Figure 2(B)). Therefore, it is preferable that the portions 46a, 46b of the solid member 46 be arranged in a staggered pattern. As a result, the unplaced portions 48a, 48b, into which the bottom adhesive members 42, 43 are filled, are also arranged in a staggered pattern symmetrically to each other in a plan view of the bottom surface 24a. As a result, even with the surface material 20 as described above, the adhesive area between the edge surfaces 26a of each sheet of glass 20a, 20b and the bottom adhesive members 42, 43 can be reliably secured. Furthermore, because the staggered arrangement of the bottom adhesive members 42, 43 equalizes the adhesive strength of the edge surfaces 26a of the surface material 20 in the indoor-outdoor direction, the support stability of the surface material 20 is improved.

[0059] In the surface material support structure 10, the bottom adhesive members 42, 43 and the side adhesive members 44, 45 can be in contact with each other. In this case, the adhesive members 42-45 are continuous from the bottom surface 24a to the side surfaces 24b, 24c of the opening groove 24, and the adhesive strength to the surface material 20 is further improved.

[0060] The panel support method of this embodiment includes the steps of applying adhesive members 42-45 (pre-process side adhesive members 44a, 45a) to the bottom surface 24a and side surfaces 24b, 24c of the opening groove 24, respectively, and then inserting the edge portion 26 of the panel material 20 into the opening groove 24 and bonding at least the edge surface 26a of the panel material 20 to the bottom surface 24a with bottom adhesive members 42, 43. Furthermore, the panel support method includes the step of applying side adhesive members 44, 45 (post-process side adhesive members 44b, 45b) between the surfaces 20d, 20e of the panel material 20 and the side walls 33, 34 to bond the surfaces 20d, 20e to the side surfaces 24b, 24d. The bead materials 40, 41 are press-fitted from the inner circumference after the post-process side adhesive members 44b, 45b are applied.

[0061] As described above, the panel support method of this embodiment performs the application process of the side adhesive members 44 and 45 in two stages. This optimizes the amount of the side adhesive members 44a and 45a applied in the first application stage, preventing contamination of the surrounding area when the edge 26 of the panel 20 is inserted into the opening groove 24. This is because if a large amount of side adhesive members 44 and 45 is filled when inserting the panel 20 into the opening groove 24, there is a concern that the side adhesive members 44 and 45 may overflow from the gap between the panel 20 and the side walls 33 and 34, causing contamination of the surrounding area. Thus, the panel support method of this embodiment can suppress the occurrence of such work defects. Furthermore, in this panel support method, the second application stage of the side adhesive members 44 and 45 is performed after inserting the panel 20 into the opening groove 24. This ensures the final amount of side adhesive members 44 and 45 filled, and also ensures the support strength of the panel 20.

[0062] In this surface material support method, the bead material 40 and 41 are pressed into the inner circumference of the side adhesive members 44 and 45 after the second coating process. This allows the bead material 40 and 41 to apply pressure to the side adhesive members 44 and 45 from the inner circumference, ensuring a sufficient degree of filling of the side adhesive members 44 and 45. As a result, the side adhesive members 44 and 45 can be filled without any gaps. However, in this second coating process, the surface material 20 can get in the way, making it difficult to insert the tip nozzle 52a into the gaps. However, in this surface material support method, the side adhesive members 44a and 45a from the previous process have already been injected into the areas where it is difficult to insert the tip nozzle 52a during the first coating process. Therefore, there is no problem with insufficient filling of the final side adhesive members 44 and 45.

[0063] The shape and arrangement of the solid members are not limited to the solid members 46 shown in Figure 2 above. Modified examples of the solid members will be described below with reference to Figures 7 to 12.

[0064] The solid member 60 shown in Figure 7 has a first part 60a and a second part 60b that have different shapes from the first part 46a and second part 46b of the solid member 46 shown in Figure 2. Parts 60a and 60b may be molded integrally rather than being separate parts. Parts 60a and 60b each have a vertical wall portion 60c that rises in the X direction at the ends facing the sides 24b and 24c of the opening groove 24. The height of the vertical wall portion 60c is lower than the height from the bottom surface 24a to the engaging pieces 33a and 34a. By having the vertical wall portion 60c, the amount of side adhesive members 44 and 45 used in the solid member 60 can be reduced.

[0065] The solid member 62 shown in Figure 8 has a roughly crank shape in a plan view of the bottom surface 24a. The solid member 62 has a rod-shaped base 62a extending in the Y direction along the center of the edge surface 26a in the indoor-outdoor direction, and rod-shaped first portion 62b and second portion 62c projecting in the indoor-outdoor direction from the end of the base 62a, respectively. The portions 62b and 62c of the solid member 62 are arranged point-symmetrically with respect to the longitudinal center of the base 62a. In the solid member 62, the portion enclosed by the base 62a, the first portion 62b, and the indoor side surface 24b is the first unplaced portion 48a. In the solid member 62, the portion enclosed by the base 62a, the second portion 62c, and the outdoor side surface 24c is the second unplaced portion 48b. The solid member 62 is formed as a narrow rod shape overall, which facilitates installation on the bottom surface 24a. The solid member 62 increases the contact area with the bottom surface 24a and edge surface 26a of the bottom adhesive members 42 and 43, thereby improving the support strength of the surface material 20.

[0066] The solid member 64 shown in Figure 9 has a roughly cross shape in a plan view of its base surface 24a. The solid member 64 has both line symmetry and point symmetry in a plan view of its base surface 24a. As a result, the solid member 64 forms two first non-placed portions 48a and two second non-placed portions 48b aligned in the Y direction. In other words, the solid member 64 divides the application area of ​​the base adhesive members 42 and 43 into four sections. By dividing the base adhesive members 42 and 43 into smaller portions, the solid member 64 can shorten the curing time for each portion.

[0067] The solid member 66 shown in Figure 10 has a first part 66a and a second part 66b that have different shapes from the first part 46a and second part 46b of the solid member 46 shown in Figure 2. The solid member 66 has a point-symmetric shape in a plan view of the bottom surface 24a. Parts 66a and 66b are molded as a single unit. The solid member 66 can reduce the curing time of the bottom adhesive members 42 and 43 by reducing their application area, and further reduce the amount used.

[0068] The solid member 68 shown in Figure 11 has a substantially H-shape in plan view of the bottom surface 24a. The solid member 68 has both line symmetry and point symmetry in plan view. The solid member 68 has a pair of notches 68a and 68b in the portion that contacts the bottom surface 24a. The notches 68a and 68b form unplaced portions 48a and 48b, respectively, into which the bottom adhesive members 42 and 43 are filled. The solid member 68 has vertical wall portions 68c that rise in the X direction at the ends facing the sides 24b and 24c of the opening groove 24. Each vertical wall portion 68c has a notch 68d into which the side adhesive members 44 and 45 are filled in part. The height of the vertical wall portions 68c is lower than the height from the bottom surface 24a to the engaging pieces 33a and 34a. The solid member 68 has bottom adhesive members 42 and 43 filled in the notches 68a and 68b, and side adhesive members 44 and 45 filled in the notches 68d of the vertical wall portion 68c. This allows the solid member 68 to reduce the amount of adhesive members 42 to 45 used while increasing the contact area with the edge surfaces 26a and surfaces 20d and 20e of the adhesive members 42 to 45.

[0069] The solid member 70 shown in Figure 12 has a first part 70a and a second part 70b that have different shapes from the first part 46a and second part 46b of the solid member 46 shown in Figure 2. The parts 70a and 70b of the solid member 70 have a trapezoidal shape when viewed from above the base surface 24a. The solid member 70 has a point-symmetrical shape when viewed from above the base surface 24a. The bottom adhesive member 42 can be applied in a trapezoidal shape along the slanted sides on both sides from the bottom of the second part 70b. The bottom adhesive member 43 can be applied in a trapezoidal shape along the slanted sides on both sides from the bottom of the first part 70a. In this way, each part 70a and 70b of the solid member 70 can be configured in a shape other than rectangular.

[0070] As described above, the panel support structure according to the first aspect of the present invention is a panel support structure that supports the edge of a panel with an opening groove of a frame material, wherein the frame material has a bottom wall that forms the bottom surface of the opening groove, a first side wall that forms the indoor side surface of the opening groove, and a second side wall that forms the outdoor side surface of the opening groove, and the panel support structure comprises a first bead material sandwiched between the indoor surface of the panel material and the first side wall, a second bead material sandwiched between the outdoor surface of the panel material and the second side wall, a bottom adhesive member filled between the edge surface of the panel material and the bottom surface of the opening groove, a first side adhesive member provided on the outer circumference of the first bead material and filled between the indoor surface of the panel material and the indoor side surface of the opening groove, and a second side adhesive member provided on the outer circumference of the second bead material and filled between the outdoor surface of the panel material and the outdoor side surface of the opening groove. With this configuration, the facing material is supported within the opening groove together with the bead material using adhesive members on three sides, thereby increasing the support strength of the facing material.

[0071] The frame material may be configured to include a solid member interposed between the bottom surface and the edge surface, wherein the installation area of ​​the solid member along the longitudinal direction of the frame material is provided with a non-placement area between the bottom surface and the edge surface where the solid member is not placed, and the bottom adhesive member may be filled at least in the non-placement area. In this configuration, the application area and amount of the bottom adhesive member can be easily controlled by visual inspection, improving work efficiency and optimizing the amount of adhesive member used.

[0072] The non-placed portion includes a first non-placed portion facing a first range that includes the portion located on the indoor side of the center of the edge surface in the indoor-outdoor direction, and a second non-placed portion facing a second range that includes the portion located on the outdoor side of the center of the edge surface in the indoor-outdoor direction. The bottom adhesive member may be configured to fill each of the first non-placed portion and the second non-placed portion. This ensures that the indoor and outdoor ends of the edge surface of the surface material are securely bonded together with the bottom adhesive member.

[0073] The solid member may have a symmetrical shape in a plan view with respect to the bottom surface, and the first non-placed portion and the second non-placed portion may be configured to be symmetrical with respect to the bottom surface. This allows for equalization of the adhesive strength of the edge surface of the surface material in the indoor and outdoor directions by the bottom adhesive member, thereby improving the support stability of the surface material.

[0074] The solid member may have a first portion adjacent to the outdoor side of the first non-placed portion and a second portion adjacent to the indoor side of the second non-placed portion, wherein the first portion and the second portion have point-symmetrical shapes with respect to the bottom surface, and the first non-placed portion and the second non-placed portion have point-symmetrical shapes with respect to the bottom surface. This configuration allows the bottom surface adhesive members to be arranged in a staggered pattern, further equalizing the adhesive strength of the edge surfaces of the surface material in the indoor-outdoor direction.

[0075] The solid member may be composed of a setting block that supports the edge surface. In this case, the solid member can be replaced with a setting block used in other parts, thereby reducing component costs.

[0076] The bottom adhesive member and the first side adhesive member may be in contact with each other, and the bottom adhesive member and the second side adhesive member may also be in contact with each other. In this configuration, the adhesive members are continuous from the bottom to the side of the opening groove, further improving the adhesive strength.

[0077] The frame material may be the meeting stile of at least one of the two sliding screens that make up a sliding window, in which the two screens are arranged to slide left and right. This ensures support strength, especially at the meeting stile, which is particularly prone to instability in supporting the facing material among the frames that make up the sliding window.

[0078] A second aspect of the present invention relates to a method for supporting a panel material, wherein the edge of the panel material is supported by an opening groove of a frame material, the frame material having a bottom wall that forms the bottom surface of the opening groove, a first side wall that forms the indoor side surface of the opening groove, and a second side wall that forms the outdoor side surface of the opening groove, and the method for supporting the panel material comprises the steps of applying an adhesive member to the bottom surface, indoor side surface and outdoor side surface of the opening groove, inserting the edge of the panel material into the opening groove after the application step, and bonding at least the edge surface of the panel material to the bottom surface with the adhesive member, and the bonding part The method includes the steps of: bonding the panel to the frame material by applying an adhesive between the indoor surface of the panel and the first side wall after the bonding step, thereby bonding the indoor surface of the panel to the indoor side surface of the opening groove, and applying an adhesive between the outdoor surface of the panel and the second side wall, thereby bonding the outdoor surface of the panel to the outdoor side surface of the opening groove; and pressing in a first bead material between the indoor surface of the panel and the first side wall, and pressing in a second bead material between the outdoor surface of the panel and the second side wall after the bonding step to the frame material. With this method, by performing the application step of the side adhesive material in two stages, work efficiency can be increased while ensuring the final amount of side adhesive material filled, thereby increasing the support strength of the panel material.

[0079] Prior to the coating step, a solid member is placed on the bottom surface of the opening groove to be interposed between the bottom surface and the edge surface of the surface material, and a non-placement area is provided in the installation range of the solid member along the longitudinal direction of the frame material where the solid member is not placed. The adhesive member to be applied to the bottom surface in the coating step is applied to at least the non-placement area, and the thickness of the adhesive member applied in the non-placement area may be the same as or greater than the thickness of the solid member. This allows for easy visual control of the application range and amount of the bottom surface adhesive member, improving work efficiency.

[0080] It should be noted that the present invention is not limited to the embodiments described above, and can be freely modified without departing from the spirit of the invention.

[0081] The above examples illustrate solid members 46 having two parts 46a and 46b. For example, the solid member 46 may be configured by arranging three or more parts 46a and 46b alternately in the Y direction, and the same applies to other solid members 60, etc. In other words, three or more unplaced parts 48a and 48b may be arranged in the Y direction.

[0082] In the above example, the panel support structure 10 is applied to a frame, but the frame material to which it can be applied may also be a frame material that constitutes an opening frame fixed to the building structure. [Explanation of Symbols]
