Description

Technical Field

[0001] The present invention relates to a fitting structure for installing fittings at an outer wall opening of a building and a method for manufacturing the same.

Background Art

[0002] Generally, a fitting device installed at an outer wall opening of a building has airtightness and watertightness to a degree that prevents the intrusion of rain and wind, but does not have a water-stopping performance that prevents water increased by a typhoon or the like from entering from the outside to the inside of the building. In recent years, there are cases where existing fitting devices as described above are required to have a water-stopping performance that prevents water intrusion due to increased water level. Therefore, in such cases, for example, by applying the structure of Patent Document 1, a newly installed door frame that is slightly smaller is fixed inside the door frame of the existing door device, and a door body is fitted inside this newly installed door frame via a watertight material with high water-stopping performance. This has been proposed.

Best Mode for Carrying Out the Invention

[0008] Next, embodiments according to the present invention will be described in detail with reference to the drawings.

[0009] The fitting structure 1 shown in FIG. 1 includes an existing frame 10 fixed to the opening Xb of the wall portion Xa of the housing X, a plurality of anchor members 20 having one end side passed through the upper frame 12 and the vertical frames 11, 11 of the existing frame 10 and connected to the wall portion X, a new frame 30 connected to the other end side of each anchor member 20 via a connecting member 40 inside the frame of the existing frame 10, a gap filling material 50 provided in the gap between the existing frame 10 and the new frame 30 to tightly seal the gap, and a fitting main body 60 that tightly closes the inside of the frame of the new frame 30 (see FIGS. 1 to 3).

[0010] In the fitting structure 1 of the illustrated example, among the existing left and right vertical frames 11, 11, upper frame 12, and lower frame 15 (see FIG. 6), the inside of the vertical frames 11, 11 and the upper frame 12 is covered by the new vertical frames 31, 31 and the upper frame 32, and the existing lower frame 15 is replaced with a new lower frame 33 (see FIG. 2). With this configuration, the height of the upper surface (sill folding surface) of the lower frame 33 is made to match that of the existing lower frame 15. As another example, it is also possible to adopt a configuration in which the inside of the existing vertical frames 11, 11, upper frame 12, and lower frame 15 is covered by new vertical frames, upper frames, and lower frames, respectively.

[0011] The housing X is, for example, a building made of reinforced concrete and has a rectangular opening Xb in the wall portion Xa whose outer surface is exposed outdoors.

[0012] Before installing the new frame 30, the existing frame 10 includes, as shown in FIG. 6, left and right vertical frames 11, 11, an upper frame 12 that laterally connects these vertical frames 11, 11 at the upper end side, and a lower frame 15 that connects the vertical frames 11, 11 at the lower end side. Each of these vertical frames 11, upper frame 12, and lower frame 15 is formed in a long shape by a hard metal material (for example, iron, stainless steel, aluminum, an alloy containing any of these, etc.).

[0013] The upper frame 12 is integrally composed of an upper frame main body 12a with a substantially concave cross-section extending outward from the frame and a suspension-shaped reinforcing member 12b straddling the opening of the upper frame main body 12a in the viewing direction (see FIGS. 2 and 6).

[0014] The inner surface of the upper frame main body 12a on the inner side of the frame is formed in a stepped shape that narrows the vertical width toward the indoor side. The surface facing the outdoors in this stepped portion functions as a door-stop surface for receiving the closed furniture body 60.

[0015] A plurality of reinforcing members 12b are provided at intervals in the circumferential direction of the existing frame 10 (in the longitudinal direction of the upper frame main body 12a according to the illustrated example). Each reinforcing member 12b is formed in a rectangular plate shape, and one end side and the other end side thereof are joined to the upper frame main body 12a by welding or the like, respectively.

[0016] As shown in FIG. 6, the upper frame 12 having the above-described configuration is connected to the inner edge of the opening Xb in the wall portion Xa via the existing anchor member 13 and the connecting member 14.

[0017] And between the existing frame 10 and the opening Xb, the existing mortar M1 is filled so as to fill the space therebetween.

[0018] The existing anchor member 13 (see FIG. 6) is a shaft-shaped member made of a hard metal material. One end side of this anchor member 13 is embedded in the existing mortar M1 and the wall portion Xa. Also, the other end side of the anchor member 13 protrudes from the inner surface of the opening Xb.

[0019] The connecting member 14 is a shaft-shaped member made of a hard metal material. One end side and the other end side of this connecting member 14 are joined to the anchor member 13 and the existing frame 10 (specifically, the upper frame 12) by welding or the like, respectively (see FIG. 6).

[0020] Each vertical frame 11 is integrally composed of left and right vertical frame bodies 11a, 11a extending in a long shape in the vertical direction, similar to the upper frame 12, and a plurality of reinforcing members (not shown) fixed to the outer portion of each vertical frame body 11a. This vertical frame 11 connects the plurality of reinforcing members to the wall portion Xa by anchor members 13, connecting members 14, etc., respectively.

[0021] Before the installation of the new frame 30 (see Fig. 6), the existing lower frame 15 is provided so as to receive the lower end portions of the left and right vertical frames 11, 11. The lower half side of this lower frame 15 is integrally fixed to the floor portion Xc by existing anchor members 13, connecting members 14, etc., similar to the upper frame 12 of the existing frame 10 (see Fig. 6).

[0022] Between the lower frame 15 and the floor portion Xc, the existing mortar M1 is filled so as to cover the anchor members 13, connecting members 14, etc. And inside the existing frame 10, an existing fixture body 16 in a substantially rectangular plate shape is mounted so as to be openable and rotatable. The lower frame 15 is removed by a process described later and replaced with the lower frame 33 of the new frame 30.

[0023] The anchor member 20 is a shaft-like member for fixing the new frame 30 to be described later to the wall portion Xa, and one end side thereof is inserted from the inside of the frame into the existing frame 10, the existing mortar M1, and the wall portion Xa (see Fig. 2). A male screw portion is provided on the other end side of the anchor member 20, and a nut-like member 21 is screwed onto this male screw portion.

[0024] The new frame 30 is configured in a substantially rectangular frame shape in front view by vertical frames 31, 31 on both left and right sides, an upper frame 32 connecting these vertical frames 31, 31 in the horizontal direction on the upper end side, and a lower frame 33 connecting the vertical frames 31, 31 in the horizontal direction on the lower end side (see Fig. 1). The vertical frame 31, the upper frame 32, and the lower frame 33 are each formed in a long shape by a hard metal material (for example, iron, stainless steel, aluminum, an alloy containing any of these, etc.).

[0025] Note that the new frame 30 illustrated in FIG. 1 has a so-called horizontal-win configuration, but it is also possible to adopt a vertical-win configuration. Further, the new frame 30 may be configured such that the separate vertical frames 31, 31, the upper frame 32, and the lower frame 33 are connected at the site or the like. Alternatively, a part or all of the vertical frames 31, 31, the upper frame 32, and the lower frame 33 may be integrally joined in advance.

[0026] The upper frame 32 is integrally composed of an upper frame body 32a having a substantially concave cross section with an opening facing the outside of the frame (upper side according to FIG. 2) and a suspension-like reinforcing member 32b straddling the opening of the upper frame body 32a in the prospective direction.

[0027] The inner surface (lower side according to FIG. 2) of the upper frame body 32a is formed in a stepped shape that narrows the vertical width toward the indoor side. A watertight material fitting portion 32a1 for fitting an elastic packing 35 described later is provided at a portion facing the outside in this stepped portion.

[0028] The watertight material fitting portion 32a1 has a substantially horizontally concave vertical cross section with an opening facing the outside, and is continuous in the extending direction (lateral width direction) of the upper frame 32.

[0029] A plurality of reinforcing members 32b are provided at intervals in the circumferential direction of the new frame 30 (longitudinal direction of the upper frame body 32a according to the illustrated example). Each reinforcing member 32b is a plate-like member having an appropriate cross-sectional shape (crank-shaped cross section according to FIG. 2), and one end side and the other end side thereof are joined to the upper frame body 32a by welding or the like, respectively.

[0030] The upper frame 32 configured as described above is integrally fixed to the wall portion Xa by the anchor member 20, the connecting member 40, and the like described above.

[0031] The connecting member 40 connects the other end side of the anchor member 20 and the upper frame 32 of the new frame 30. Specifically, this connecting member 40 includes a base member 41 provided on the other end side of the anchor member 20, and a joining member 42 having one end joined to the base member 41 and the other end joined to the upper frame 32 of the newly installed frame 30.

[0032] The base member 41 is formed in a plate shape from a hard metal material, is annularly mounted on the lower end side of the anchor member 20, and is sandwiched and fixed between the upper frame body 12a and the nut-shaped member 21. This base member 41 can be in any of the modes shown in FIGS. 4(a) to (c).

[0033] The base member 41 shown in FIG. 4(a) is formed in a rectangular flat plate shape and has a through hole 41a for inserting the anchor member 20 near its center. A plurality of such base members 41 are provided corresponding to a plurality of anchor members 20 along the circumferential direction of the existing frame 10. Each base member 41 has the anchor member 20 inserted through the through hole 41a and is sandwiched and fixed between the existing frame 10 and the nut-shaped member 21. A joining member 42, which will be described later, is joined to each of the plurality of base members 41.

[0034] The base member 41' shown in FIG. 4(b) is formed in an angled shape with a reinforcing piece 41b provided on the base member 41 and is used in substantially the same manner as the base member 41. This base member 41' has the reinforcing piece 41b arranged downward facing the vertical frame 31, has the anchor member 20 inserted through the through hole 41a, and is sandwiched and fixed between the existing frame 10 and the nut-shaped member 21.

[0035] The base member 41'' shown in FIG. 4(c) extends in the circumferential direction of the existing frame 10 so as to straddle a plurality of anchor members 20 and has a plurality of through holes 41a spaced apart in the extending direction. For this base member 41'', the anchor members 20 are respectively inserted through the plurality of through holes 41a, and the nut-shaped member 21 that screws onto the anchor member 20 is tightened, whereby it is sandwiched and fixed between the existing frame 10 and the nut-shaped member 21. And a plurality of joining members 42, which will be described later, are provided on this base member 41'' at intervals in the extending direction of the base member 41''.

[0036] The joint member 42 is a shaft-shaped member made of a hard metal material. One end side and the other end side of this joint member 42 are joined to the base member 41 (41' or 41") and the reinforcing member 32b, respectively, by welding or the like (see Fig. 2).

[0037] Also, each vertical frame 31 is integrally composed of left and right vertical frame bodies 31a, 31a extending in a long shape in the vertical direction, similar to the upper frame 32, and a plurality of suspension-shaped reinforcing members 31b fixed to the outer frame portions of the respective vertical frame bodies 31a. Each of the plurality of reinforcing members 31b is connected to the wall portion Xa by an anchor member 20, a connecting member 40, etc.

[0038] The surface on the inner side of the frame of the vertical frame body 31a (left side according to Fig. 3) is formed in a stepped shape that narrows the lateral width toward the indoor side. On the portion facing the outdoors in this stepped portion, a watertight material fitting portion 31a1 for fitting the elastic packing 35 described later is provided. This watertight material fitting portion 31a1 has a substantially horizontally concave cross-section facing the outdoor side, similar to the watertight material fitting portion 32a1 of the upper frame 32, and is continuous in the extending direction (vertical direction) of the vertical frame 31.

[0039] Also, the lower frame 33 is integrally composed of a lower frame body 33a having a substantially reverse concave cross-section with the opening facing the outer side of the frame (lower side according to Fig. 2), and a suspension-shaped reinforcing member 33b straddling the opening of the upper frame body 32a in the prospective direction.

[0040] The surface on the inner side of the frame of the lower frame body 33a (upper side according to Fig. 2) is formed in a stepped shape that narrows the vertical width toward the indoor side. On the portion facing the outdoors in this stepped portion, a watertight material fitting portion 33a1 for fitting the elastic packing 35 is provided.

[0041] The watertight material fitting portion 33a1 has a substantially horizontally concave cross-section facing the outdoor side, similar to the watertight material fitting portion 32a1 of the upper frame 32, and is continuous in the extending direction (lateral width direction) of the lower frame 33.

[0042] A plurality of reinforcing members 33b are provided at intervals in the circumferential direction of the new frame 30. Each reinforcing member 33b is a plate-like member having an appropriate cross-sectional shape (in accordance with FIG. 2, substantially L-shaped in cross section), and one end side and the other end side thereof are joined to the lower frame body 33a by welding or the like, respectively.

[0043] The lower frame 33 configured as described above is fixed to the bottom surface of the recess Xc1 of the floor portion Xc by new anchor members 37 and connecting members 38 and the like. And between the lower frame 33 and the floor portion Xc, new mortar M2 is filled so as to cover the anchor members 37 and the connecting members 38 and the like. Note that, as the new anchor members 37 and connecting members 38, members substantially the same as the existing anchor members 13 and connecting members 14 may be used.

[0044] The gap filling material 50 is provided in the space between the existing upper frame 12 and the new upper frame 32, and in the space between the existing vertical frame 11 and the new vertical frame 31. This gap filling material 50 includes new mortar M2 filled closer to the indoor side of the space, waterproof material 51 filled closer to the outdoor side of the space, and backup material 52 provided between these mortar M2 and waterproof material 51, and closes the gap between the existing frame 10 and the new frame 30 in a watertight manner.

[0045] The new mortar M2 may be a general cement mortar obtained by kneading sand (fine aggregate), cement, and water. Preferably, a mortar having good strength and waterproofness, such as polymer cement mortar or resin mortar, is selected.

[0046] The waterproof material 51 is a caulking material that cures in an elastic state after filling to exhibit waterproofness, and includes, for example, silicon, modified silicon, epoxy, etc. as raw materials.

[0047] The backup material 52 may be any material that partitions the waterproof material 51 and the mortar M2. For example, it is possible to use a polyethylene foam, wood, or other solid materials. This backup material 52 is inserted between the upper frame 12 and the upper frame 32 from the outdoor side and is positioned in contact with the flange portion 32a2 facing outward of the upper frame 32 (see Fig. 2). Similarly, the backup material 52 is inserted between the vertical frame 11 and the vertical frame 31 from the outdoor side and is positioned in contact with the flange portion 31c facing outward of the vertical frame 31 (see Fig. 3).

[0048] The elastic packing 35 is fitted into the watertight material fitting portions 33a1 of the upper frame 32, the watertight material fitting portions 31a1 of the left and right vertical frames 31, and the watertight material fitting portion 33a1 of the lower frame 33, and is configured in a rectangular frame shape when viewed from the front along the new frame 30. This elastic packing 35 is formed of an elastic material such as rubber or an elastomer resin, and is sandwiched between the closed furniture body 60 and the new frame 30 and elastically deformed to maintain watertightness between them.

[0049] The furniture body 60 constitutes a door body having an appropriate thickness from a front plate and a back plate spaced apart in the thickness direction and a frame member or the like therebetween. One end side in the lateral width direction of this furniture body 60 is supported by one vertical frame 31 of the new frame 30 via a hinge (not shown), and by rotating about this support portion, the space inside the new frame 30 is closed or opened. This furniture body 60 is loosely fitted inside the new frame 30 in the closed state and is pressed against the elastic packing 35 to close the inside of the new frame 30 in a substantially watertight manner.

[0050] <Regarding the manufacturing method> Next, the manufacturing method features of the furniture structure 1 having the above configuration will be described in detail. First, in an existing furniture structure (see Fig. 6), the existing furniture body 16 is removed from the existing frame 10.

[0051] Next, the lower frame 15 of the existing frame 10 is removed (see Fig. 7). Specifically, chisel off the mortar M2 that fixes the lower frame 15, cut the connection parts between the connecting member 14 and the lower frame 15, the connection parts between the lower frame 15 and the vertical frame 11, etc., remove the lower frame 15, and also remove the existing connecting member 14, anchor member 13, etc. by cutting or the like.

[0052] Next, chisel off the floor part Xc to form a recess Xc1 into which the lower frame 33 of the newly installed frame 30 can be inserted (see Fig. 8).

[0053] Next, as shown in Fig. 9, install a newly provided anchor member 37 on the bottom surface of the recess Xc1 of the floor part Xc. Also, drill upward continuous holes in the existing upper frame 12, the existing mortar M1, and the wall part Xa, and insert and fix the anchor member 20 into these holes. That is, one end side of the anchor member 20 penetrates the existing frame 10 (upper frame 12) and is connected to the building structure X (wall part Xa). Then, a base member 41 or the like is attached to this anchor member 20.

[0054] Next, as shown in Fig. 10, fit and position the newly provided lower frame 33 in the lower recess Xc1, and weld a connecting member 38 between this lower frame 33 and the anchor member 37 to fix the lower frame 33. On the other hand, newly provided vertical frames 31, 31 and an upper frame 32 are installed and positioned above the lower frame 33.

[0055] After that, inside the frame of the existing frame 10, the newly installed frame 30 is connected to the other end side of the anchor member 20. More specifically, weld a connecting member 40 between the base member 41 on the side of the existing upper frame 12 and the newly provided upper frame 32 (see Fig. 10), and between the base member 41 on the side of the existing vertical frame 11 and the newly provided vertical frame 31 (see Fig. 3) respectively to fix the newly provided vertical frame 31 and upper frame 32.

[0056] Next, as shown in Fig. 11, a backup material 52 and a waterproof material 51 are inserted into the gaps between the existing upper frame 12 and the newly provided upper frame 32, and between the existing vertical frame 11 and the newly provided vertical frame 31 from the outdoor side (see Fig. 6) respectively. Then, mortar M2 is filled between the newly installed lower frame 33 and the recess Xc1 and hardened. Furthermore, mortar M2 is also filled and hardened from the indoor side between the existing upper frame 12 and the newly installed upper frame 32, and between the existing vertical frame 11 and the newly installed vertical frame 31.

[0057] Next, as shown in FIG. 12, an elastic packing 35 is fitted to the newly installed frame 30, and the fixture body 60 is suspended via a hinge (not shown).

[0058] <Function and Effect> According to the fixture structure 1 with the above configuration and its manufacturing method, the vertical frame 31 and the upper frame 32 of the newly installed frame 30 can be directly and promptly connected to the wall portion Xa of the building body X by the newly installed anchor member 20, the connecting member 40, etc. Also, the lower frame 33 of the newly installed frame 30 is directly and promptly connected to the floor portion Xc of the building body X by the newly installed anchor member 37, the connecting member 38, etc. Therefore, the newly installed frame 30 can be firmly connected to the building body X, the workability is good, and as a result, it is possible to prevent the existing frame 10 and the newly installed frame 30 from coming off the building body X due to water pressure.

[0059] <Modification Example> According to the above embodiment, the existing frame 10 and the newly installed frame 30 are connected via the base member 41 and the joint member 42. However, as another example, the base member 41 can be omitted, and the joint member 42 can be directly connected (such as welded) to the anchor member 20 and the newly installed frame 30, or the base member 41 and the joint member 42 can be omitted, and the anchor member 20 can be directly connected to the newly installed frame 30.

[0060] The existing frame 10 in the illustrated example has a so-called vertical-win configuration, but the fixture structure 1 according to the present invention is also applicable to an existing frame with a horizontal-win configuration. Similarly, the newly installed frame 30 in the illustrated example has a so-called horizontal-win configuration, but the fixture structure 1 according to the present invention can also have a vertical-win newly installed frame.

[0061] According to the above embodiment, the object to be mounted such as the existing frame 10 is the concrete structure X. However, as another example of this structure X, it is also possible to use a wooden building, other buildings, vehicles, ships, etc. For these other examples, waterproof treatment is performed on the wall portion Xa around the opening Xb and between the existing frame 10 and the opening Xb as necessary.

[0062] In the above embodiment, the fitting structure according to the present invention is applied to a hinged door. However, the fitting structure according to the present invention can also be applied to, for example, a sliding door, a folding door, or other fittings.

[0063] In the above embodiment, the fitting body 60 (door body) in the new frame 30 is provided so as to be openable and closable. However, as another example, it is also possible to configure a so-called built-in fitting in which the fitting body in the new frame 30 is non-openable and non-closable.

[0064] Further, the present invention is not limited to the above-described specific configuration, and can be appropriately changed without changing the gist of the present invention.
