Description

[Technical Field]

[0001] The present disclosure relates to a method for assembling a glass door. [Background technology]

[0002] Glass doors are made up of a glass panel and a frame material surrounding the glass panel, and are used in many building fixtures, such as sliding doors in automatic door systems and glass shoji screens in window systems.

[0003] For example, as described in JP 2020-90773 A (Patent Document 1), the edge of a glass panel that constitutes a glass door is inserted and held in a panel holding groove provided in a frame material that constitutes a frame material. The gap between the edge of the panel surface of the glass panel and the panel holding groove is sealed with a sealant. The sealant ensures waterproofness and airtightness between the glass panel and the frame material, and also fixes the glass panel and the frame material together.

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-90773 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventionally, glass doors are assembled by inserting the edge of the glass panel into a panel holding groove provided in the frame, then applying a sealant between the edge of the panel surface of the glass panel and the panel holding groove, and allowing the sealant to dry and harden.

[0006] However, it takes several days for the sealant to completely dry and harden. Therefore, after the sealant is applied, the glass door must be left in the same position as when the sealant was applied, for example, leaning against the stand, and cannot be moved for several days. Therefore, to assemble multiple glass doors, multiple stands are required, and a large assembly space is required.

[0007] The present disclosure has been made to solve the above-mentioned problems, and aims to provide a method for assembling a glass door that can reduce the amount of assembly space required.

[0008] In recent years, there has been an increasing demand for frameless glass doors, reducing the visibility of the frame material surrounding the glass panel in order to enhance the design of automatic door and window systems. To address this issue, one approach to reducing the visibility of the frame material is to make the frame width smaller than that of conventional frame structures (for example, 25 mm or less). However, frame materials with narrower frame widths have reduced rigidity and are more prone to bending. This makes it difficult to properly control the positional relationship between the frame material and the glass panel when applying a sealant, and makes it difficult to create a space between the panel retaining groove and the edge of the panel surface for applying the sealant. This can lead to poor workability when assembling glass doors using conventional assembly methods. Therefore, an object of the present disclosure is to provide a glass door assembly method that can suppress a decrease in workability even when frame materials with a small clearance width are used as needed. [Means for solving the problem]

[0009] A glass door assembly method according to one aspect of the present disclosure includes an inserting step, an adhering step, a sealant application step, and a sealant drying step. The inserting step is a step of inserting an end of the glass panel into a panel holding groove provided in the frame member. The bonding step is a step of injecting an adhesive into a gap between the panel holding groove and the edge of the glass panel after the inserting step, and hardening the adhesive. The sealant application step is a step of applying a sealant between the edge of the panel surface of the glass panel and the panel holding groove after the bonding step. The seal drying step is a step of drying the seal material after the seal application step.

[0010] In the glass door assembling method according to one aspect of the present disclosure, a narrow stile with a viewing width (W) of 25 mm or less can be used as the stile material.

[0011] In a glass door assembly method according to one aspect of the present disclosure, the panel retaining groove and the end of the glass panel can be bonded together so as to surround the end of the glass panel on three sides in the cross section of the frame. In this case, the glass panel can have a first panel surface, a second panel surface facing the opposite side to the first panel surface in the plate thickness direction, and a panel end surface, and the panel retaining groove can have a first groove inner surface, a second groove inner surface facing the first groove inner surface, and a groove bottom surface. The adhesive is used to bond between the edge of the first panel surface and the inner side of the first groove, between the edge of the second panel surface and the inner side of the second groove, and between the panel end face and the groove bottom face, thereby bonding the end of the glass panel so that it surrounds it from three sides. Furthermore, in this case, the bottom surface of the groove can have a crank-shaped cross section in the cross section of the frame member. The cross section of the frame member refers to a cross section obtained by cutting the frame member along an imaginary plane perpendicular to the longitudinal direction of the frame member.

[0012] In a glass door assembly method according to one aspect of the present disclosure, after inserting the end of the glass panel into the panel holding groove, the frame and the glass panel can be temporarily fixed together using a jig such as a band or fastener. In this case, the temporary fixation can be released after the adhering step and before the sealant application step.

[0013] In the glass door assembly method according to one aspect of the present disclosure, the adhesive can be injected from above while the thickness direction of the glass panel is aligned with the vertical direction. Alternatively, in a glass door assembly method according to one aspect of the present disclosure, the adhesive can be injected from both left and right sides or one side of the glass panel while the thickness direction of the glass panel is aligned in the left-right direction.

[0014] In the glass door assembling method according to one aspect of the present disclosure, the seal drying step can be carried out in a location different from the seal application step.

[0015] In the glass door assembly method according to one aspect of the present disclosure, the adhesive can be injected into multiple locations along the longitudinal direction of the frame material. Alternatively, in a glass door assembly method according to one aspect of the present disclosure, the adhesive can be injected at only one location along the length of the frame, or it can be injected along the entire length of the frame.

[0016] In the glass door assembly method according to one aspect of the present disclosure, in the inserting step, when the end of the glass panel is inserted into the panel holding groove, a plurality of spacer blocks can be sandwiched between the groove bottom surface of the panel holding groove and the panel end surface of the glass panel, with gaps between the blocks. Also, in the bonding step, the adhesive can be injected into the gaps between the blocks to bond the groove bottom surface and the panel end surface. [Effects of the Invention]

[0017] According to the glass door assembling method according to one aspect of the present disclosure, it is possible to reduce the assembly space required.

[0018] Furthermore, the glass door assembly method according to one aspect of the present disclosure can prevent a decrease in the workability of the glass door assembly work even when using frame materials with a small visibility width. [Brief explanation of the drawings]

[0020] [First example of embodiment] A first example of the embodiment will be described with reference to FIGS.

[0021] In this example, a sliding door 1 incorporated into an automatic door system will be used as an example of a glass door. However, the assembly method of the present disclosure can also be applied to other glass doors, such as glass shoji screens and glass doors, in addition to sliding doors.

[0022] below, sliding door After explaining the overall structure of the sliding door 1, the method of assembling the sliding door 1 will be explained. In the following description, the vertical and horizontal directions refer to the directions when the sliding door 1 is viewed from the front after being installed in an automatic door system. The out-of-plane direction refers to the depth direction (thickness direction) of the sliding door 1.

[0023] [Sliding door structure] The sliding door 1 has a glass panel 2 and a frame member 3 surrounding the periphery of the glass panel 2.

[0024] Glass Panel The glass panel 2 is a single-pane glass and is configured in a rectangular plate shape. However, the glass panel may also be a double-glazed glass. Furthermore, the shape of the glass panel is not limited to a rectangular plate shape, and other shapes may also be adopted.

[0025] The glass panel 2 has a first panel surface 4, a second panel surface 5 facing the opposite side to the first panel surface 4 in the thickness direction of the glass panel 2, a pair of side end faces 6, an upper end face 7, and a lower end face 8.

[0026] The first panel surface 4 and the second panel surface 5 constitute both surfaces in the thickness direction of the glass panel 2. A pair of side end surfaces 6, an upper end surface 7, and a lower end surface 8 respectively constitute the four sides of the glass panel 2. The outer peripheral edges of the first panel surface 4 and the second panel surface 5 are connected to the pair of side end surfaces 6, the upper end surface 7, and the lower end surface 8, respectively.

[0027] The pair of side end faces 6 extend in the vertical direction and are arranged parallel to each other. The upper end face 7 and the lower end face 8 extend in the left-right direction and are arranged parallel to each other. The side end face 6 is arranged at right angles to the upper end face 7 and the lower end face 8, respectively.

[0028] 《Stile frame material》 The frame material 3 has a pair of vertical frames 9, an upper frame 10, and a lower frame 11. The pair of vertical frames 9, the upper frame 10, and the lower frame 11 are connected at their respective ends to form a rectangular frame.

[0029] In this example, as will be described later, the assembly method of the present disclosure is applied to the process of assembling the glass panel 2 and the vertical frame 9. Therefore, the vertical frame 9 corresponds to the frame material recited in the claims, and the side end surface 6 of the glass panel 2 corresponds to the panel end surface recited in the claims. However, the assembly method of the present disclosure is not limited to the process of assembling the vertical frame and the glass panel, and can also be applied to the process of assembling the upper frame and / or the lower frame and the glass panel.

[0030] Each of the vertical frame 9, the upper frame 10 and the lower frame 11 is made of an aluminum alloy.

[0031] In addition, to make the left and right vertical stiles 9 of the sliding door 1 less noticeable, the width (W) of the vertical stiles 9 is set to 25 mm or less, which is smaller than the width (35 mm) of the vertical stiles of a conventional sliding door. In other words, a so-called narrow width stile is used as the vertical stile 9. Specifically, the ratio of the width to the vertical length of the vertical stile 9 (W / L) can be set to 0.0083 or less. In this example, the width of the vertical stile 9 is set to 9 mm, and the vertical length (L) of the vertical stile 9 is set to 3000 mm. Therefore, the ratio of the width to the vertical length of the vertical stile 9 (W / L) is 0.003.

[0032] The vertical frame 9 comprises a pair of rectangular cylindrical portions 12a, 12b that extend vertically and are spaced apart from each other in the out-of-plane direction, and a connecting plate portion 13 that connects these rectangular cylindrical portions 12a, 12b.

[0033] The connecting plate portion 13 has a crank-shaped cross section in the cross section of the vertical frame 9. The middle portion of the connecting plate portion 13 in the out-of-plane direction is configured as a flat plate, while the ends on both sides of the connecting plate portion 13 in the out-of-plane direction are bent in a generally L-shaped cross section. The cross section of the vertical frame 9 refers to the cross section when the vertical frame 9 is cut along an imaginary plane perpendicular to the longitudinal direction of the vertical frame 9.

[0034] The vertical frame 9 has a panel holding groove 14a on the inner peripheral portion of the vertical frame 9 surrounded on three sides by the two rectangular tubular portions 12a, 12b and the connecting plate portion 13.

[0035] The panel retaining groove 14a has a first groove inner surface 15 formed by the inner surface of one rectangular tubular portion 12a, a second groove inner surface 16 formed by the inner surface of the other rectangular tubular portion 12b, and a groove bottom surface 17 formed by the inner peripheral surface of the connecting plate portion 13, and has an approximately U-shaped outline in the cross section of the vertical frame 9.

[0036] The groove bottom surface 17 is formed by the inner peripheral surface of the connecting plate portion 13, and therefore has a crank-shaped cross section in the transverse section of the vertical frame 9.

[0037] The left-right side edges of the glass panel 2 are inserted and held in the panel holding grooves 14a. Specifically, the side edges of the glass panel 2 are held in the panel holding grooves 14a by adhesive 19 and a pair of sealants 20a, 20b, with spacer blocks 18 sandwiched between the side end faces 6 and the out-of-plane middle portions of the groove bottom surfaces 17.

[0038] A plurality of spacer blocks 18 are provided in the longitudinal direction of the vertical frame 9, with inter-block gaps 21 between them. A plurality of inter-block gaps 21 (approximately two to five) are provided, and are arranged at equal intervals in the longitudinal direction of the vertical frame 9. Specifically, the inter-block gaps 21 are arranged at intervals of 400 mm to 700 mm, preferably at intervals of 500 mm to 600 mm. The length of each inter-block gap 21 is approximately 20 mm to 60 mm, preferably approximately 30 mm to 50 mm. The interval between the inter-block gaps 21 refers to the distance (pitch) between the centers of adjacent inter-block gaps 21. The length of the inter-block gap 21 refers to the length between the end faces of adjacent spacer blocks 18.

[0039] The adhesive 19 bonds and fixes the panel holding groove 14a and the side edge of the glass panel 2 together.

[0040] In this example, the adhesive 19 bonds and fixes the panel holding groove 14a to the side end of the glass panel 2 at portions that align with the inter-block gaps 21 in the longitudinal direction of the stile 9. In other words, the adhesive 19 bonds and fixes the panel holding groove 14a to the side end of the glass panel 2 at multiple locations that are offset from the spacer blocks 18 in the longitudinal direction of the stile 9. In other words, the adhesive 19 is filled in the inter-block gaps 21 and the panel holding groove 14a.

[0041] The adhesive 19 bonds the innermost portion of the panel holding groove 14a to the side edge of the glass panel 2 in a manner surrounding the side edge of the glass panel 2 from three sides in the cross section of the vertical frame 9.

[0042] Specifically, the adhesive 19 bonds between the left-right side edge portions of the first panel surface 4 and the first groove inner surface 15, between the left-right side edge portions of the second panel surface 5 and the second groove inner surface 16, and between the side end surface 6 and the groove bottom surface 17. The portion of the adhesive 19 that bonds the side end surface 6 of the glass panel 2 and the groove bottom surface 17 of the panel holding groove 14a fills the gap 21 between the blocks.

[0043] The adhesive 19 used in this example can be of any type as long as it has a shorter drying time (hardening time) than the sealing materials 20a and 20b, but for example, ``Hardlock (two-component type)'' manufactured by Denka Co., Ltd. can be used.

[0044] The sealants 20a and 20b are disposed closer to the opening of the panel holding groove 14a than the adhesive 19. The sealant 20a seals the gap between the side edge of the first panel surface 4 and the first groove inner surface 15 over the entire length. The sealant 20b seals the gap between the side edge of the second panel surface 5 and the second groove inner surface 16 over the entire length.

[0045] The upper frame 10 has a panel holding groove 14b that opens downward. The upper end of the glass panel 2 is inserted and held in the panel holding groove 14b. Specifically, the upper end of the glass panel 2 is held in the panel holding groove 14b by a pair of sealing materials 20c, 20d and a pair of backup materials 22a, 22b.

[0046] The sealant 20c contacts the backup material 22a and forms a seal between the upper edge of the first panel surface 4 and the panel retaining groove 14b over the entire length. The sealant 20d contacts the backup material 22b and forms a seal between the upper edge of the second panel surface 5 and the panel retaining groove 14b.

[0047] The lower frame 11 has a panel holding groove 14c that opens upward. The lower end of the glass panel 2 is inserted into and held in the panel holding groove 14c. Specifically, the lower end of the glass panel 2 is held in the panel holding groove 14c by a pair of seal members 20e, 20f and a pair of backup members 22c, 22d, with a spacer block 23 sandwiched between the lower end face 8 and the groove bottom of the panel holding groove 14c.

[0048] Sealant 20e contacts back-up material 22c and provides a seal between the lower edge of first panel surface 4 and panel retaining groove 14c over the entire length. Sealant 20f contacts back-up material 22d and provides a seal between the lower edge of second panel surface 5 and panel retaining groove 14c over the entire length.

[0049] [How to assemble a sliding door] Next, a description will be given of a method for assembling the sliding door 1 of this embodiment. In this embodiment, in order to assemble the sliding door 1 having the above-described configuration, an insertion process, an adhesion process, a sealant application process, and a sealant drying process are carried out in this order.

[0050] <Insertion process> In the insertion step, the side edge of the glass panel 2 is inserted into the panel holding groove 14a of the vertical frame 9. For this purpose, a plurality of spacer blocks 18 are attached in advance to the groove bottom surface 17 of the panel holding groove 14a, leaving a predetermined gap 21 between the blocks. In addition, a mark is attached using masking tape or the like to a portion of the vertical frame 9 that is visible from the outside and that aligns with the gap 21 between the blocks in the longitudinal direction.

[0051] In the insertion process of this example, not only are the side ends of the glass panel 2 inserted into the panel holding groove 14a of the vertical frame 9, but also the upper end of the glass panel 2 is inserted into the panel holding groove 14b of the upper frame 10, and the lower end of the glass panel 2 is inserted into the panel holding groove 14c of the lower frame 11. For this purpose, one of the pair of backup members 22a, 22b (22a or 22b) is attached in advance to the panel holding groove 14b of the upper frame 10. In addition, one of the pair of backup members 22c, 22d (22c or 22d) and the spacer block 23 are attached in advance to the panel holding groove 14c of the lower frame 11. The other backup material 22b (or 22a) of the pair of backup materials 22a, 22b, and the other backup material 22d (or 22c) of the pair of backup materials 22c, 22d are attached after the ends of the glass panel 2 are inserted into the panel holding grooves 14b, 14c.

[0052] As shown in Fig. 6, the insertion step is performed by placing the glass panel 2 on a workbench 25 with the plate thickness direction aligned with the vertical direction. Specifically, with the glass panel 2 placed on the workbench 25, the side ends of the glass panel 2 are inserted into the panel holding grooves 14a of the pair of vertical frames 9, the upper end of the glass panel 2 is inserted into the panel holding grooves 14b of the upper frame 10, and the lower end of the glass panel 2 is inserted into the panel holding grooves 14c of the lower frame 11. In this way, the pair of vertical frames 9, upper frame 10, and lower frame 11 are attached so as to cover the four sides of the glass panel 2, respectively. Then, the respective ends of the pair of vertical frames 9, upper frame 10, and lower frame 11 are connected by screws or the like.

[0053] In this example, when the side end of the glass panel 2 is inserted into the panel holding groove 14a of the vertical frame 9, a plurality of spacer blocks 18 are sandwiched between the side end face 6 of the glass panel 2 and the groove bottom face 17 of the vertical frame 9. Furthermore, when the upper end of the glass panel 2 is inserted into the panel holding groove 14b of the upper frame 10, a pair of backup members 22a, 22b hold the upper end of the glass panel 2 in the thickness direction (vertical direction) of the glass panel 2. Furthermore, when the lower end of the glass panel 2 is inserted into the panel holding groove 14c of the lower frame 11, a pair of backup members 22c, 22d hold the lower end of the glass panel 2 in the thickness direction of the glass panel 2, and sandwich a spacer block 23 between the lower end face 8 of the glass panel 2 and the groove bottom face of the lower frame 11.

[0054] In the insertion step of this example, after inserting the side end of the glass panel 2 into the panel holding groove 14a, the vertical frame 9 and the glass panel 2 are temporarily fixed together. Specifically, as shown in Fig. 7, a band 26, which is a jig, is wrapped around the pair of vertical frame 9 and glass panel 2, thereby temporarily fixing the vertical frame 9 and the glass panel 2 together. The band 26 can be wrapped around a portion of the vertical frame 9 adjacent to the inter-block gap 21 in the longitudinal direction.

[0055] When temporarily fixing the vertical frame 9 and the glass panel 2, a joint gap 24 for injecting adhesive 19 is formed in the gap between the panel holding groove 14a and the side end of the glass panel 2. In other words, the gap between the panel holding groove 14a and the side end of the glass panel 2 is divided into the joint gap 24 for injecting adhesive 19 and the other portion.

[0056] Specifically, as shown in FIG. 8 , first jig members 27 are clamped on both sides of a portion of the gap between the side edge of the first panel surface 4 and the first groove inner surface 15 that aligns with the inter-block gap 21 in the longitudinal direction of the stile 9. Furthermore, a second jig member 28 is clamped in a range including a portion of the gap between the side edge of the second panel surface 5 and the second groove inner surface 16 that aligns with the inter-block gap 21 in the longitudinal direction of the stile 9. This forms a joint gap 24 that includes the inter-block gap 21 in the portion of the gap between the panel holding groove 14a and the side end of the glass panel 2 that aligns with the inter-block gap 21 in the longitudinal direction of the stile 9. The joint gap 24 has a substantially U-shaped cross section in the transverse cross section of the stile 9. A backup material made of urethane foam resin can be used for the first jig member 27 and the second jig member 28.

[0057] When the glass panel 2 is placed on the workbench with the second panel surface 5 facing upward, the first jig members 27 can be clamped on both sides of the portion between the side edge of the second panel surface 5 and the second groove inner surface 16 that aligns with the inter-block gap 21 in the longitudinal direction of the vertical frame 9, and the second jig member 28 can be clamped in a range including the portion between the side edge of the first panel surface 4 and the first groove inner surface 15 that aligns with the inter-block gap 21 in the longitudinal direction of the vertical frame 9.

[0058] In addition, masking tape is applied to the surface of the vertical frame 9, the first panel surface 4, and the second panel surface 5 to prevent the adhesive 19 from adhering thereto during the bonding process.

[0059] <Adhesion process> In the bonding process, adhesive 19 is injected into the joint gaps 24 and allowed to harden within the joint gaps 24. In this example, joint gaps 24 are provided at multiple locations along the longitudinal direction of the vertical stile 9 within the gaps between the panel holding grooves 14a and the side ends of the glass panel 2. For this reason, adhesive 19 is injected into each of the multiple joint gaps 24.

[0060] In this example, as shown in Figure 7, the bonding process is carried out without moving the glass panel 2 and the frame material 3 from the workbench 25 used in the insertion process, and the adhesive 19 is injected into the joint gap 24 from above.

[0061] Specifically, adhesive 19 is injected into joint gaps 24 between the side edges of the first panel surface 4 and the first groove inner surface 15, using the portion between the pair of first jig members 27 (the portion indicated by arrow X in FIG. 8) as an inlet. The injected adhesive 19 passes through inter-block gaps 21 and reaches the portion between the side edges of the second panel surface 5 and the second groove inner surface 16. The adhesive 19 then hardens in the inter-block gaps 21, which are the portions between the side edges of the first panel surface 4 and the first groove inner surface 15, the portions between the side edges of the second panel surface 5 and the second groove inner surface 16, and the portions between the side end surfaces 6 and the groove bottom surface 17.

[0062] The adhesive usually dries and hardens within a few hours. The hardening time varies depending on the type, but for example, when "Hardlock (two-component type)" manufactured by Denka Co., Ltd. is used as the adhesive 19 in this example, it dries and hardens within about 15 to 30 minutes.

[0063] As a result, the adhesive 19 bonds between the side edges of the first panel surface 4 and the first groove inner surface 15, between the side edges of the second panel surface 5 and the second groove inner surface 16, and between the side end surface 6 and the groove bottom surface 17. As a result, the frame material 3 (a pair of vertical stiles 9, an upper stile 10, and a lower stile 11) is adhesively fixed to the glass panel 2.

[0064] The adhesive 19 that has reached the portion between the side edge of the second panel surface 5 and the second groove inner surface 16 is prevented from dripping out of the joint gap 24 by the second jig member 28. In other words, the second jig member 28 blocks the exit of the joint gap 24.

[0065] After the adhesive 19 has hardened, it is left for several tens of minutes (for example, 30 minutes or more), and then the first jig member 27 and the second jig member 28 are removed, and the masking tape is removed. The band 26 is also removed, and the temporary fixation between the vertical frame 9 and the glass panel 2 is released. Note that even if the bonding work needs to be redone after the adhesive 19 has hardened, the adhesive 19 can be softened and cut by heating it with a tool such as a hot gun, making it easy to redo the bonding work.

[0066] <Seal application process> After the bonding step, as shown in FIG. 9, the glass panel 2 and the frame material 3 are moved from the workbench 25 to the stand 29, and in a state where they are leaned against the stand 29, a sealant application step is carried out.

[0067] In the sealant application process, a sealant is applied between the outer peripheral edge of the first panel surface 4 and the frame member 3. Specifically, a sealant 20a is applied between the side edge of the first panel surface 4 and the first groove inner surface 15. A sealant 20c is also applied between the upper edge of the first panel surface 4 and the panel holding groove 14b. Furthermore, a sealant 20e is applied between the lower edge of the first panel surface 4 and the panel holding groove 14c.

[0068] Next, a sealant is applied between the outer peripheral edge of the second panel surface 5 and the frame member 3. Specifically, sealant 20b is applied between the side edge of the second panel surface 5 and the second groove inner surface 16. Also, sealant 20d is applied between the upper edge of the second panel surface 5 and the panel holding groove 14b. Furthermore, sealant 20f is applied between the lower edge of the second panel surface 5 and the panel holding groove 14c.

[0069] In this example, after the sealing materials 20a to 20f are applied using a seal gun or the like, the shapes of the sealing materials 20a to 20f are adjusted using a spatula or the like.

[0070] It does not matter whether the step of applying a sealant between the outer peripheral edge of the first panel surface 4 and the frame material 3 and the step of applying a sealant between the outer peripheral edge of the second panel surface 5 and the frame material 3 are performed in order. The structure of the mount 29 is not particularly limited and can be changed as appropriate.

[0071] <Seal drying process> After the sealant application step, a sealant drying step is carried out to dry the sealants 20a to 20f.

[0072] In this example, by performing the bonding process before the sealant application process, the glass panel 2 and the frame material 3 including the vertical stiles 9 are bonded and fixed together, so that the glass panel 2 and the frame material 3 can be moved after the sealant 20a-20f has been applied. Therefore, in this example, the sealant drying process is performed in a location different from the sealant application process. Specifically, as shown in Fig. 10, the glass panel 2 and the frame material 3 are moved from the stand 29 where the sealant application process was performed to the transport vehicle 30, and are left on the transport vehicle 30 for several days to dry the sealant 20a-20f.

[0073] The transport vehicle 30 can be moved from the space where the platform 29 is installed to an unused space in a factory, or from the factory to an installation site for an automatic door device. In other words, the time spent transporting the sliding door 1 can be used for the seal drying process. The structure of the transport vehicle 30 is not particularly limited and can be modified as appropriate. Furthermore, the seal drying process can be performed in a location different from the transport vehicle.

[0074] In this example, the sliding door 1 is assembled through the steps described above.

[0075] In the present embodiment as described above, the space required for assembling the sliding door 1 can be saved. That is, in this example, an adhesive process not employed in conventional assembly methods is provided before the sealant application process, and the glass panel 2 and the frame member 3 including the vertical stile 9 are adhesively fixed together. Therefore, after the sealants 20a-20f have been applied, the glass panel 2 and the frame member 3 can be removed from the frame 29 before the sealants 20a-20f dry. Therefore, even when assembling multiple sliding doors 1, fewer frame members 29 are required than the number of sliding doors 1 to be assembled (a minimum of one is required). This allows for space saving when assembling the sliding doors 1.

[0076] Furthermore, although the sliding door 1 of this example uses a stile 9 with a narrow find width, by adhesively fixing the glass panel 2 and the stile 9 together in the bonding process, the positional relationship between the glass panel 2 and the stile 9 can be properly regulated before the sealant application process. As a result, before the sealant application process, spaces for applying the sealants 20a, 20b can be formed between the side edges of the first panel surface 4 and the first groove inner surface 15, and between the side edges of the second panel surface 5 and the second groove inner surface 16. Therefore, even when a stile 9 with a narrow find width is used, the ease of assembly of the sliding door 1 can be prevented from being reduced.

[0077] In this example, the vertical frame 9 and the glass panel 2 are temporarily fixed using the band 26 during the insertion process, which prevents the positional relationship between the vertical frame 9 and the glass panel 2 from becoming improper during the bonding process. Also, the attachment position of the band 26 that temporarily fixes the vertical frame 9 and the glass panel 2 is set at a position away from the position where the adhesive 19 is injected, which prevents the band 26 from getting in the way during the bonding process. Furthermore, the adhesive 19 hardens in a shorter time than the sealants 20a to 20f, which sufficiently prevents a decrease in the workability of the assembly work of the sliding door 1.

[0078] Furthermore, in this example, the seal drying process can be performed on the transport vehicle 30, so the transport time of the sliding door 1 can be used for the seal drying process. Therefore, the lead time of the sliding door 1 can be shortened.

[0079] In this example, the adhesive 19 bonds the panel holding groove 14a of the vertical frame 9 to the side edge of the glass panel 2 so as to surround the side edge of the glass panel 2 from three sides in the cross section of the vertical frame 9, thereby ensuring a sufficient bonding area between the vertical frame 9 and the panel holding groove 14a and ensuring the bonding strength between the vertical frame 9 and the panel holding groove 14a. Furthermore, in this example, the cross section of the groove bottom surface 17 of the panel holding groove 14a is crank-shaped, so that a sufficient bonding area between the vertical frame 9 and the panel holding groove 14a can be ensured and the bonding strength can be increased.

[0080] Although the embodiments of the present disclosure have been described above, the technical concept of the present disclosure is not limited to these and can be modified as appropriate.

[0081] The technical concept of the present disclosure is not limited to the assembly method described in the embodiment. For example, other processes can be inserted between each process. Furthermore, the position of the glass panel in each process is not limited to the position described in the embodiment and can be changed as appropriate. Furthermore, although the embodiment describes a case where the technical concept of the present disclosure is applied to an assembly process of a vertical frame and a glass panel, the technical concept of the present disclosure is not limited to a vertical frame and can be applied to an assembly process of other frame materials and a glass panel.
