Description

[Technical Field]

[0001] The present invention relates to a construction method for installing a frame member for providing a top-hung sliding door that opens and closes an opening formed in a wall or partition, and to a sliding door unit. [Background technology]

[0002] Walls, partitions, etc. are provided to separate "predetermined spaces" such as rooms, while openings are formed in the walls, partitions, etc. to allow access to the "predetermined spaces." In addition, such openings are sometimes provided with opening / closing bodies that open and close the openings. One such opening and closing body is a top-hung sliding door, and Patent Document 1 discloses a technique for improving the workability of installing a frame (a pre-assembled frame) for a sliding door.

[0003] [Patent Document 1] Patent No. 6228493 Summary of the Invention [Problem to be solved by the invention]

[0004] For example, when installing a sliding door in a toilet booth, it is usually installed on the inside of the booth. If it were installed on the outside, the sliding door mechanism would be on the outside, making it easier to access from the outside, which is undesirable from a security standpoint (and taking separate measures to prevent this would be costly). When trying to install a sliding door inside a small space such as a toilet booth, the working space is also limited. The technology disclosed in Patent Document 1 involves assembling a four-sided frame in advance and then attaching it, but installing such a pre-assembled frame can be difficult or impossible in environments with limited work space. Also, installing a pre-assembled frame is not necessarily easy to do by one person.

[0005] In view of the above, the present invention aims to provide a construction method and a sliding door unit that are easy to install frame members for providing a sliding door even in a relatively small work space, or a construction method and a sliding door unit that are easy to install frame members even when the installation is done by one person.

DETAILED DESCRIPTION OF THE INVENTION

[0026] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be realized, and are not intended to limit the scope of the present invention.

[0027] 1 to 3 are diagrams showing an installed state of a sliding door unit according to an embodiment of the present invention, with FIG. 1 being a front view, FIG. 2 being a cross-sectional view, and FIG. 3 being a vertical cross-sectional view. In this embodiment, a toilet booth is used as an example of a location where the sliding door unit 1 is installed. The toilet booth is formed by being partitioned with a panel body 2 and has an opening that serves as an entrance and exit, and the sliding door unit 1 is provided as an overhead sliding door that opens and closes this opening. The sliding door unit 1 is installed on the indoor side of the toilet booth. Note that Figure 2 shows an example of a toilet booth where two sides are partitioned by panel bodies (the other two sides are formed by the building frame (not shown) or the like). As shown in Figures 1 to 3, the sliding door unit 1 includes: Sliding door 14 and A guide rail (guide member) 13 that slides the sliding door 14 in an overhead manner; a guide rail (guide member) 13 for installing the guide rail (guide member) 13 at the top of the opening G; The vertical frame 11 is a vertical frame that forms the door stop of the sliding door 14, and is equipped with an upper frame load-receiving portion 113 (see Figure 8) at the top that supports one end of the upper frame 12 when the upper frame 12 is installed above the opening G.

[0028] The vertical frame 11 and the transom 12 are frame members for installing a top-hung sliding door. The present invention mainly relates to the frame members and the construction method for installing them.

[0029] The frame 11 is installed on the wall surface (side panel 2S2) on the side of the opening G via a C channel 111, and forms a door stop on the door tip side of the sliding door . As shown in the cross-sectional views of Figures 6(b) and 7(b), the vertical frame 11 is basically a hollow member, and both end sides of the wall-facing side surface 115 extend toward the wall, thereby forming recesses 114 that open toward the wall. The recesses 114 are portions that receive and engage the C-channels 111, and are formed with protrusions 1141 on the inner surface that come into contact with the C-channels 111. This makes it easy to insert the C-channels 111 into the recesses 114, and allows the vertical frame 11 to engage with the C-channels 111 without rattle. Additionally, thread grooves 116 are formed on the inner surface of the hollow portion of the vertical frame 11 to receive tapping screws for attaching the top surface member. The screw grooves 116 are formed along the longitudinal direction (vertical direction) of the vertical frame 11 and also function as protrusions that come into contact with the C-channels 112, which are floor fixing members, thereby allowing the vertical frame 11 to engage with the C-channels 112 without rattle. Here, the screw grooves are configured to also have the function of coming into contact with the C-channels 112, but it goes without saying that the member that comes into contact with the C-channels 112 may be formed separately from the screw grooves. Furthermore, the protrusions 1141 that come into contact with the C-channels 111 inside the recesses 114 may be configured as screw grooves. An upper frame load receiving portion 113 (see Figure 8), which is an L-shaped member (angle bar), is attached to the upper part of the vertical frame 11 to support one end of the transom 12 when assembling the transom 12. In addition, the vertical frame 11 is configured as a door stop on the door edge side, and is equipped with a recess formed at the point where the door edge of the sliding door 141 comes into contact, and a key engagement hole 118 that engages with a key provided on the sliding door 141.

[0030] As shown in Figure 3, the transom 12 is installed on the wall (upper panel 2T) above the opening G, and is a member that supports the guide rail 13 that slidably suspends the sliding door 14, the automatic closing device (a mechanical mechanism that allows the sliding door 14 to close automatically and slowly) 15, etc. Also, a cover 16 is attached to the transom 12 to cover the guide rail 13 and other mechanical parts. 12, the transom 12 is basically a hollow member, and includes a beam 121 on the underside of which the guide rail 13 and the like are attached, and a mounting plate 122 that serves as the mounting surface for the wall surface (upper panel 2T). The transom 12 is formed with protrusions that serve as positioning members such as the guide rail 13 to be attached, thread grooves for tapping screws, screw holes, and a partition plate that is provided within the hollow for reinforcement.

[0031] The sliding door mechanism supported by the frame member (guide rail 13, sliding door 14, automatic closing device 15, and associated components, etc.) can be any mechanism, so detailed explanation will be omitted here. In this embodiment, a double sliding door having sliding doors 141 and 142 and equipped with an automatic closing device is used as an example, but the present invention is not limited to this and any sliding door can be used.

[0032] Figures 4 to 11 are explanatory diagrams illustrating a construction method for installing the frame members (jam 11 and transom 12) of the sliding door unit 1. Note that the layout is reversed from left to right compared to Figures 1 to 3, but this does not result in any conceptual difference.

[0033] First, the vertical frame 11 is installed on the wall surface (side panel 2S2) on the side of the opening G. In this embodiment, a C-channel (vertical frame base material) 111 is used to install the vertical frame 11 on the wall surface (side panel 2S2). Also, a C-channel 112 is used as a floor fixing member to prevent the vertical frame 11 from shaking (shaking around the attachment part to the wall surface).

[0034] FIG. 4 is an explanatory diagram relating to the installation of a C channel 111, which is a vertical frame base material, in which FIG. 4(a) is a perspective view seen from the interior side of the toilet booth, and FIG. 4(b) is a cross-sectional view. As shown in FIG. 4, the C channel 111 is fixed to the side panel 2S2 that is the side portion of the opening G by being fastened with a plurality of screws. Figure 5 is an explanatory diagram regarding the installation of the C channel 112, which is a floor fixing member, where Figure 5(a) is an oblique view seen from the inside of the toilet booth, Figure 5(b) is an enlarged view of the lower end portion of Figure 5(a), and Figure 5(c) is a cross-sectional view. As shown in Figure 5, the C channel 112 is oriented so as to be perpendicular to the wall surface of the side panel 2S2, and is positioned so that one end engages with the C channel 111, and is fixed by being screwed to the floor surface.

[0035] 6 and 7 are explanatory diagrams relating to the installation of the vertical frame 11, with Fig. 6(a) and Fig. 7(a) being perspective views seen from the inside of the toilet booth, and Fig. 6(b) and Fig. 7(b) being cross-sectional views. As shown in Figures 6 and 7, the vertical frame 11 is slid toward the wall surface (side panel 2S2) to engage the vertical frame 11 with the C channel 111 and C channel 112. Because each component has the configuration described above, this operation is easy to perform and the vertical frame 11 can be engaged with the C channel 111 and C channel 112 without any rattle. At the lower end of the vertical frame 11, the side surface 115 of the vertical frame 11 is cut out, so that when the vertical frame 11 is slid into engagement, the side surface 115 does not interfere with the engagement of the C channel (floor fixing member) 112 at the bottom of the vertical frame 11. After sliding the vertical frame 11 into the C channel 111 and the C channel 112 to engage them, the vertical frame 11 is fixed to the C channel (vertical frame base material) 111 by screwing the vertical frame 11 and the C channel 111 together with a plurality of screws, as shown in Fig. 7. The vertical frame 11 and the C channel (floor fixing member) 112 may also be fixed together with screws or the like.

[0036] Figures 8 to 11 are explanatory diagrams regarding the installation of the transom 12, with Figure 8 being an oblique view seen from the inside of the toilet booth, Figure 9(a) being an enlarged front view of the joint between the vertical frame 11 and the transom 12, Figure 9(b) being a vertical cross-sectional view of the same part, Figure 10 being an oblique view seen from the inside of the toilet booth, Figure 11(a) being an enlarged oblique view of the joint between the vertical frame 11 and the transom 12, Figure 11(b) being an enlarged front view of the joint between the vertical frame 11 and the transom 12, and Figure 11(c) being a vertical cross-sectional view of the same part. As mentioned above, an upper frame load receiving portion 113 is provided on the top of the vertical frame 11, and this upper frame load receiving portion 113 is inserted into the inside of the beam portion 121 of the crossbeam 12, which is a hollow member (see Figures 8 and 9). This allows the upper frame load receiving portion 113 to support one end of the crossbeam 12, which improves the workability of installing the crossbeam 12. Furthermore, because the upper frame load receiving portion 113 is installed at a predetermined height based on a pre-designed position, the crossbeam 12 can be positioned at an accurate height. One end of the transom (upper frame) 12 is supported by the upper frame load receiving portion 113, and then the transom (upper frame) 12 is installed above the opening G. More specifically, with one end of the transom 12 hooked onto the frame load receiving portion 113, another point of the transom 12 is supported by hand, and while leveling the transom 12, the mounting plate 122 of the transom 12 is screwed to the wall surface (upper panel 2T) with multiple screws SC (Figure 10). The work can be done relatively easily even by a single worker. In addition, a cushioning sheet (a PVC sheet in this embodiment) is pre-attached to the back side of the mounting plate 122 to absorb the effects of small irregularities and steps on the wall surface (panel body) (for example, steps that occur at the end portions of each panel body), and the PVC sheet is placed between the mounting plate 122 and the wall surface. As shown in Figure 11, the installation of the vertical frame 11 and the transom 12 is completed by fastening the transom (upper frame) 12 to the upper frame load-receiving portion 113 with screws SC. When screwing the upper frame load-receiving portion 113 and the transom 12 together, the side of the transom 12 and the side of the vertical frame 11 are joined together so that there is no gap between them, allowing the vertical frame 11 to be installed at a closer to a right angle to the wall surface.

[0037] As described above, according to the sliding door unit 1 and its installation method of this embodiment, one end of the transom 12 can be supported by the upper frame load-receiving portion 113, which makes it easy to install the transom 12. The transom 12 can be a long member depending on the size of the opening G, and the task of installing it at a predetermined height (a relatively high position) while leveling it horizontally can tend to be a complicated job, but according to this embodiment, this task is easy to do and can be easily performed by one person. As a result, even in a relatively small work space such as a toilet booth, the installation of the frame members for installing the sliding door is easy and can be performed easily by one person. Furthermore, since the upper frame load receiving portion 113 is attached at a predetermined height based on a design in advance, the interlock 12 can also be positioned at an accurate height. Note that "the upper frame load receiving portion 113 is attached to the vertical frame 11 in advance" includes not only the case where the upper frame load receiving portion 113 is attached to the vertical frame 11 at the time of shipping from the factory, but also the case where the upper frame load receiving portion 113 is attached to the vertical frame 11 at the construction site (at least before the interlock 12 is attached).

[0038] As another configuration for making it easier to hold the transom when installing it, the transom may be hooked onto a fastener such as a screw provided on the wall surface. More specifically, a step of providing a fastener that protrudes partially from the wall surface above the opening within the range where the upper frame is to be installed (for example, by driving a screw with its head protruding from the wall surface); The construction method may also include a step in which the upper frame is provided with a hanger portion, and the hanger portion is hooked onto a part of the fastening body, and then the upper frame is installed above the opening. FIG. 12 is a diagram relating to the construction method, and is a vertical cross-sectional view showing the state in which the transom 12 is installed on the wall surface (upper panel 2T) above the opening G. A hanger portion 123 is formed as a recess on the surface of the crossbeam portion 121 of the crossbeam 12 that faces the wall surface. One or more screws SC are driven into the wall surface (upper panel 2T) at a position opposite the hanger part 123, and the hanger part 123 is hooked onto the screw SC at a position where the screw SC protrudes from the wall surface to support the lintel 12, and in this state, the mounting plate 122 of the lintel 12 is screwed to the wall surface. This improves the workability of installing the transom even when no vertical frame is provided. Of course, it can also be used in conjunction with the provision of a vertical frame (when using the upper frame load-receiving portion). Here, the hanger portion 123 is a recessed portion, but the present invention is not limited to this, and any configuration that can hook onto a part of a fastener protruding from a wall surface is possible. For example, the hanger portion may be formed by forming a hole in the eyelet 12 large enough to allow part of the fastener to pass through. Also, although a screw is used as the fastener, the present invention is not limited to this (for example, a nail may be used).

[0039] In cases where a partition is made up of panels, such as a toilet booth, there may be no panel above the opening (it may be open). Without an upper panel or coping, a transom cannot be installed. Therefore, we will explain how to install a panel above the opening so that a transom can be installed when the top of the opening is open.

[0040] Figures 13 to 16 are explanatory diagrams regarding the installation of the transom panel, with Figures 13 and 14 being cross-sectional views of the open portion O at the top of the opening of the toilet booth, Figure 15 being a cross-sectional view of the same location with the transom panel installed, and Figure 16 being a front view. In this method, a transom panel 172 is used, which has slide engaging portions 171 attached to both ends of the open portion O at the top of the opening, and engaged portions 1721 that engage with the slide engaging portions 171 at both ends. The slide engagement portion 171 is a square pipe-shaped member, and is connected to the panel body (side panel 2S1, It has a thickness about half that of the 2S2. The transom panel 172 is basically a panel body similar to the side panels 2S1 and 2S2, and has engaged portions 1721, which are recesses that receive the slide engaging portions 171, formed on both end surfaces thereof. As shown in Figure 13, when there is no panel body above the opening, leaving an open area O, slide engagement portions 171 are attached to both ends of the open area O (i.e., the end faces of the side panels 2S1 and 2S2) (Figure 14). Next, adhesive is applied to one or both of the slide engaging portion 171 and the engaged portion 1721, and the transom panel 172 is slid from bottom to top to engage the engaged portion 1721 with the slide engaging portion 171. Once the transom panel 172 is placed in the specified position, screws are inserted through both the slide engaging portion 171 and the engaged portion 1721 within the range where the transom (upper frame) 12 will be installed (screws SC in Figures 15 and 16). Note that the fasteners that fasten the slide engaging portion 171 and the engaged portion 1721 are not limited to screws (nails, etc. may be used). Furthermore, the fasteners are used to hold the transom panel 172 in place until the adhesive hardens, and are not essential. This allows the transom panel 172 to be fixed to the top of the opening, and a transom (upper frame) can be installed for the transom panel 172. According to the above method, it is possible to prevent the components for installing the transom panel from appearing on the design surface, resulting in excellent design properties. It is more preferable to set the fastener that passes through both the slide engaging portion 171 and the engaged portion 1721 as a fastener for hooking the hanger portion 123 described in FIG.

[0041] In the case of the present embodiment, in which the upper frame load receiving portion 113 is provided so as to protrude from the side of the vertical frame 11 and is inserted into the hollow crossbeam 12 (beam portion 121), the vertical frame 11 cannot be removed unless the crossbeam 12 is removed. In this case, if the vertical frame is deformed or damaged by being hit by an object or the like, removing and attaching the crossbeam is necessary to replace the vertical frame. FIG. 17 shows a configuration that allows the vertical frame to be replaced in such a case without the need to remove and attach the transom. The transom 12 shown in Figure 17 has a slit 124 formed therein to allow the upper frame load-receiving portion 113 (a member for supporting the transom) to pass through so that the vertical frame 11 can be removed by sliding it away from the opening wall surface. As a result, as shown in Figure 17(b), by removing the screws SC that fasten the upper frame load-receiving portion 113 to the interlining 12 and then removing the screws that fasten the vertical frame 11 to the C channel (vertical frame base material) 111, the vertical frame 11 can be removed by sliding it forward (away from the wall surface) without having to remove or attach the interlining 12.

[0042] In the embodiment, an example is given in which the upper frame load-receiving portion is constructed by attaching an L-shaped member (angle member), but the present invention is not limited to this, and any shaped member that can support the interlock (upper frame) can be used. Furthermore, in the embodiment, an upper frame load-receiving portion is provided so as to protrude from the side of the vertical frame and is configured to be inserted into the hollow interior of the crossbeam, but the present invention is not limited to this. For example, a portion protruding toward the crossbeam (upper frame) may be provided and supported by a hole (or upper end) provided in the vertical frame. In this case, the hole (or upper end) of the vertical frame corresponds to the "upper frame load-receiving portion provided in the vertical frame." Note that, in a configuration in which a portion protruding toward the crossbeam is provided and inserted into a hole provided in the vertical frame, the "slit" described in Figure 17 would be provided on the vertical frame.

[0043] In the embodiment, a toilet booth has been described as an example of the installation location of the sliding door unit, but the installation target of the sliding door unit of the present invention is not limited to this and it can be used for any opening (an opening formed in a wall or partition that separates a "specified space" such as a room).

[0044] In this embodiment, an example is given in which the vertical frame is installed on a wall surface via a C channel (vertical frame base material), but the present invention is not limited to this, and for example, the vertical frame base material may be made of components of other shapes and installed on a wall surface, or the vertical frame may be attached directly to the wall surface (without using a vertical frame base material). Similarly, in this embodiment, a C-channel is used as a floor fixing member to prevent the vertical frame from shaking, but the present invention is not limited to this, and for example, members of other shapes may be used as floor fixing members, or the vertical frame may be fixed directly to the floor surface. Note that a configuration for preventing the shaking of floor fixing members, etc. is not essential. [Explanation of symbols]
