Description

[Technical Field]

[0001] The present invention relates to a renovation fitting in which at least a portion of an existing frame material is covered with a new frame material, and a method for constructing the renovation fitting. [Background technology]

[0002] When renovating a fixture, the existing frame material of the existing frame is left in the building, and new frame material of a new frame is installed, covering at least a portion of the existing frame material. Next, an exterior material (for example, an outer frame) is installed on the exterior side of the building, and a door body for renovation is installed. Furthermore, as a structure for such renovated fixtures, a frame member installation structure has been known in the past in which a new frame is installed on the inner periphery of the existing frame, and a frame member, which is an exterior material, is attached to the new frame (see Patent Document 1).

[0003] In the conventional frame member mounting structure described in Patent Document 1, a spacer is interposed between the existing frame and the new frame, and the exterior side of the spacer is sealed with a sealant. In this way, the spacer placement and sealing with a sealant, which are incidental to the installation of the new frame member in the building, are carried out on the existing frame member side of the existing frame, which is the outer periphery of the new frame member. Furthermore, the frame member is fixed and connected to the exterior side of the new frame member with connecting screws, and the frame member covers the existing frame member from the exterior side.

[0004] However, if components such as door hinges are placed on the exterior facing of the new frame, or if the exterior facing is slimmed down as a result of the new frame being slimmer, it may be difficult to connect the frame members to the exterior facing of the new frame. In such cases, it is necessary to connect the frame members to a location other than the exterior facing of the new frame. However, if the shape of the new frame is changed to connect the frame members, depending on the shape of the new frame, it may become difficult to perform additional work on the outer periphery of the new frame, which may affect the workability of the renovation fittings.

[0010] An embodiment of a remodeling fixture and a method for constructing the remodeling fixture of the present invention will be described with reference to the drawings. The renovated fixture of this embodiment is a fixture that has been renovated from an existing fixture installed in a building with a new fixture for renovation, and comprises an existing frame material of the existing frame and a new frame material of the new frame. The renovated fixture is also installed in the building using the renovated fixture installation method of this embodiment. Below, two embodiments of the renovated fixture and the installation method for the renovated fixture will be explained, taking the case where the renovated fixture is a renovated door as an example. Therefore, the existing fixture is an existing door, and the new fixture is a newly installed door.

[0011] (First embodiment) FIG. 1 is a front view showing a remodeling fitting 1 of the first embodiment, showing the schematic configuration of the remodeling fitting 1 installed in a building 10 as seen from outside the room. As shown in the figure, the remodeled fitting 1 is an entrance door installed at the entrance of a building 10, and is positioned between the interior (indoor) and exterior (outdoor) of the building 10. The remodeled fitting 1 is also a single-leaf door, and is installed at an opening 11 of the building 10.

[0012] When the remodeling fitting 1 installed in the building 10 is viewed from the front, the direction that is up and down is the up-down direction R, and the direction that is left and right is the left-right direction S. In Figure 1, the up-down direction R is the vertical direction, and the left-right direction S is the horizontal direction. The indoor / outdoor direction is the indoor / outdoor direction (indoor / outdoor direction) of the remodeling fitting 1 installed in the building 10. Furthermore, the indoor / outdoor direction is the front-to-back direction (depth direction) and the thickness direction of the remodeling fitting 1 when viewed from the front of the remodeling fitting 1 installed in the building 10, and in Figure 1 is the horizontal direction perpendicular to the left-to-right direction S. In this way, the directions related to the remodeling fitting 1 are specified as the directions when it is installed in the building 10. Furthermore, the indoor side and outdoor side of the remodeling fitting 1 are the indoor side and outdoor side when it is installed in the building 10.

[0013] The renovated fixture 1 comprises an existing frame of an existing fixture (not shown in Figure 1) and a new fixture 2 used to renovate the existing fixture. The new fixture 2 comprises a new frame 3 that renovates the existing frame, and a door body 4 (shown by a two-dot chain line) that opens and closes by pivoting. The new frame 3 is a square opening frame (new door frame) that surrounds the door body 4. The door body 4 is a panel body that can be opened and closed, and is connected to the new frame 3 by multiple hinges 4A and 4B so that it can be opened and closed. The hinges 4A and 4B are pivot hinges that connect the upper and lower parts of the door body 4 to the new frame 3.

[0014] The door body 4 is disposed inside the new frame 3 (opening 3A), and opens and closes by moving between the outside of the room and the new frame 3 side (inside of the room) by rotating around two upper and lower hinges 4A, 4B. When opening and closing, the door body 4 moves (rotates) from a closed position inside the new frame 3 toward an open position outside the room to open, and moves from the open position toward the closed position on the new frame 3 side to close. The closed position of the door body 4 is the position where the door body 4 is located when the door body 4 is closed (fully closed position), and the open position of the door body 4 is the position where the door body 4 is located when the door body 4 is opened (fully open position). The door body 4 opens and closes by moving between the closed position and the open position by rotating. The opening 3A of the new frame 3 is opened and closed by the door body 4 opening and closing.

[0015] The new frame 3 has four new frame members 20, 30, 40 (a new upper frame member 20, a new lower frame member 30, and a pair of new vertical frame members 40) that are combined with each other. The opening 3A is formed in a rectangular shape by the new frame members 20, 30, 40 and the new frame 3, and is located inside the new frame 3. The new frame members 20, 30, 40 are frame members (new frame components) that make up the new frame 3, and are arranged along the outer periphery of the door body 4. The new upper frame member 20 and the new lower frame member 30 are new horizontal frame members located at the top and bottom of the new frame 3, and extend in the horizontal direction (left-right direction S). The pair of new vertical frame members 40 are new side frame members located on the left and right sides of the new frame 3, and extend in the vertical direction (up-down direction R). The ends of the new upper frame member 20, the new lower frame member 30, and the left and right new vertical frame members 40 are connected to form a framework for the new frame members 20, 30, 40. The door body 4 is connected to one of the pair of new vertical frame members 40 by hinges 4A and 4B.

The outer frame 64 is attached to the connecting member 70 on the outdoor side of the connecting member 70, is held by the connecting member 70, and is connected to the new vertical frame member 40 via the connecting member 70.

[0039] The connecting material 70 is located at the outside end of the new vertical frame material 40, extends in the longitudinal direction of the new vertical frame material 40, and is provided over the entire longitudinal direction of the new vertical frame material 40. The connecting material 70 also has an attachment portion 71 that is attached to the new vertical frame material 40, and an attachment portion 72 to which the outer frame 64 is attached. The connecting material 70, attachment portion 71, and attachment portion 72 are located on the outer periphery of the new vertical frame material 40 relative to the outer periphery-side projection portion 46 and the outside-side projection portion 43 of the new vertical frame material 40, and the connecting material 70 and attachment portion 71 are arranged in the outer periphery-side projection portion 46.

[0040] The attachment portion 71 protrudes from the mounting portion 72 toward the inside of the room and is arranged along the projection direction G of the new vertical frame member 40. The attachment portion 71 is also located at the outside end of the outer periphery projection portion 46, is attached to the outer periphery projection portion 46, and is held by the outer periphery projection portion 46 and the new vertical frame member 40. In this way, the connecting member 70 is located on the outer periphery of the outer periphery projection portion 46 and is attached to the outer periphery projection portion 46, connecting the outer frame 64 to the outer periphery projection portion 46.

[0041] The mounting portion 72 is located on the exterior side of the mounting portion 71 and is positioned adjacent to the exterior-facing portion 43 of the new vertical frame member 40 on the outer periphery of the new vertical frame member 40. The mounting portion 72 is an exterior-facing piece that is positioned along the facing direction F of the new vertical frame member 40 and is continuous with the exterior-facing portion 43 in the facing direction F of the new vertical frame member 40. The mounting portion 72 is connected to the exterior end of the mounting portion 71 and protrudes from the mounting portion 71, the exterior-facing portion 43, and the outer periphery-side facing portion 46 in the facing direction F of the new vertical frame member 40. The outer frame 64 abuts against the mounting portion 72 from the exterior side and is attached to the mounting portion 72 by screws 6F, which are fasteners, and is held by the mounting portion 72 and the connecting member 70. The screws 6F are covered and shielded from the exterior side by covering materials 65 attached to the outer frame 64.

[0042] The mounting portion 72 has a groove 73 that is cut when adjusting the dimension of the mounting portion 72. Here, the dimension of the mounting portion 72 is the dimension of the mounting portion 72 in the view direction F of the new vertical frame member 40. The mounting portion 72 also has a plurality of grooves 73 for cutting (breaking off) that are formed at intervals from one another in the view direction F of the new vertical frame member 40. The plurality of grooves 73 extend in the longitudinal direction of the new vertical frame member 40 and are formed parallel to one another on the mounting portion 72. The dimension of the mounting portion 72 in the view direction F of the new vertical frame member 40 can be adjusted by cutting at the grooves 73. When cutting the mounting portion 72, the mounting portion 72 is cut along the grooves 73 using a cutting tool (for example, a cutter), or the mounting portion 72 is broken off at the grooves 73. In this way, by cutting the mounting portion 72 at the groove portion 73, the dimension of the mounting portion 72 in the viewing direction F of the newly installed vertical frame material 40 and the protruding dimension of the mounting portion 72 protruding from the mounting portion 71 are adjusted.

[0043] The outer peripheral projection 46 of the new vertical frame member 40 has an engagement groove 47 with which the mounting portion 71 of the connecting member 70 engages. The engagement groove 47 is located at the outdoor end of the outer peripheral projection 46, extends in the longitudinal direction of the new vertical frame member 40, and is open toward the outdoor side. The engagement groove 47 is formed in a concave shape that is recessed toward the indoor side, and is positioned facing the outdoor side. The outer peripheral projection 46 is bent at the engagement groove 47 in the viewing direction F of the new vertical frame member 40.

[0044] The mounting portion 71 of the connecting member 70 has a retaining portion 74 that protrudes toward the interior side of the room and a fixing portion 75 that is fixed to the new vertical frame member 40. The mounting portion 71, retaining portion 74, and fixing portion 75 are located on the interior side of the mounting portion 72. The retaining portion 74 is inserted into the engagement groove portion 47 of the outer peripheral projection portion 46 from the exterior side of the room, engages with the engagement groove portion 47 inside the engagement groove portion 47, and is held by the engagement groove portion 47 and the outer peripheral projection portion 46. To hold the retaining portion 74 in the engagement groove portion 47, the mounting portion 71 of the connecting member 70 is slid along the outer peripheral projection portion 46 from the exterior side to the interior side of the room, and the retaining portion 74 is inserted into the inside of the engagement groove portion 47 from the exterior side of the engagement groove portion 47. This positions the retaining portion 74 in a position where it engages with the engagement groove portion 47 (a position inside the engagement groove portion 47).

[0045] The retaining portion 74 is located on the outdoor side of the fixing portion 75, and is located between the mounting portion 72 and the fixing portion 75 in the projection direction G of the new vertical frame member 40. The fixing portion 75 is located on the indoor side of the retaining portion 74 and the engaging groove portion 47, and is fixed to the outer peripheral projection portion 46 of the new vertical frame member 40 by a fastener, a screw 6G. The mounting portion 71 of the connecting member 70 is attached to the outer peripheral projection portion 46 and the new vertical frame member 40 by the engagement of the retaining portion 74 with the engaging groove portion 47 and the fixation of the fixing portion 75 to the outer peripheral projection portion 46, and is held by the outer peripheral projection portion 46 and the new vertical frame member 40.

[0046] The fasteners for the fixing portions 75 are screws 6G, which are arranged along the viewing direction F of the new vertical frame member 40. The screws 6G are inserted through insertion holes 48 formed in the outer peripheral projection portion 46 and attached to screw holes 76 formed in the fixing portions 75. The fixing portions 75 have guide grooves 77 formed between the insertion holes 48 and the screw holes 76, and the screws 6G are inserted through the insertion holes 48 and guided to the screw holes 76 by the guide grooves 77. The screws 6G are also inserted through the insertion holes 48 from the inner peripheral side of the new vertical frame member 40 and screwed into the screw holes 76. As a result, the screws 6G are threaded into the screw holes 76 and attached to the screw holes 76. The fixing portions 75 are fixed to the outer peripheral projection portion 46 by the screws 6G, for example, at two locations spaced apart in the longitudinal direction of the new vertical frame member 40.

[0047] 7 to 9 are cross-sectional views showing the construction procedure for the remodeling fitting 1 of the first embodiment, and each shows an intermediate stage in the construction of the remodeling fitting 1. FIG. As shown in the figure, when constructing the renovated fitting 1, reinforcing members 61 are fixed to the existing vertical frame members 53 remaining in the building 10 (see FIG. 7). Next, new vertical frame members 40 are placed at the installation location in the building 10, and ancillary work is carried out on the outer periphery of the new vertical frame members 40 (see FIG. 8). The ancillary work is work carried out on the outer periphery of the new vertical frame members 40 as ancillary to the installation of the new vertical frame members 40 in the building 10.

[0048] Here, as an additional task, the work of inserting spacers 60 is performed. At that time, the spacers 60 are inserted between the existing vertical frame member 53 and the new vertical frame member 40 (the outer peripheral projection portion 46) from the outside of the room, and the spacers 60 are positioned between the existing vertical frame member 53 and the new vertical frame member 40. In addition, adjustment work is performed on the new vertical frame member 40 to adjust the state of the new vertical frame member 40 so that it can be installed in the building 10. The adjustment work on the new vertical frame member 40 includes, for example, adjusting the distortion of the new vertical frame member 40 and adjusting the position of the new vertical frame member 40. Next, the new vertical frame member 40 is attached to the reinforcing member 61, and the new vertical frame member 40 is attached to the skeleton 12 of the building 10 with the mounting members 5, and the new vertical frame member 40 is installed in the building 10.

[0049] Sealing work is performed on the outer periphery of the new vertical frame member 40, and a sealant is applied to seal the waterproof areas with the sealant. On the indoor side of the new vertical frame member 40, the inner frame 63 is fixed to the skeleton 12 of the building 10. On the outdoor side of the existing vertical frame member 53, connecting members 70 are attached to the new vertical frame member 40 on the outer periphery of the new vertical frame member 40 (see Figure 9). Next, the outer frame 64 is attached to the connecting members 70, and the outer frame 64 is connected to the new vertical frame member 40 by the connecting members 70 (see Figure 4). In this way, the renovated fitting 1 is installed at the location of the new vertical frame member 40.

[0050] In the remodeled fitting 1 described above, the connecting member 70 enables the outer frame 64 to be connected to a location other than the exterior facing portion 43 of the new vertical frame member 40. Furthermore, the connecting member 70 is attached to the new vertical frame member 40 as a separate member from the new vertical frame member 40, and incidental work can be easily performed on the outer periphery of the new vertical frame member 40 without the connecting member 70 attached to the new vertical frame member 40. This ensures the ease of installation of the remodeled fitting 1. The outer frame 64 can also be easily connected to the new vertical frame member 40 via the connecting member 70. This facilitates installation of the remodeled fitting 1, improving its ease of installation.

[0051] The outer frame 64 can be easily attached to the mounting portion 72 of the connecting material 70 on the outdoor side of the mounting portion 71 of the connecting material 70 attached to the outer periphery projection portion 46 of the new vertical frame member 40, and the outer frame 64 can also be easily connected to the outer periphery projection portion 46 of the new vertical frame member 40. In addition, the groove portion 73 provided in the mounting portion 72 makes it easy to cut the mounting portion 72 and adjust the dimensions of the mounting portion 72 by cutting. This makes it easy to adjust the dimensions of the mounting portion 72 even when it is necessary to adjust the dimensions of the mounting portion 72 in accordance with the distance between the wall surface of the building 10 and the outer periphery projection portion 46.

[0052] By engaging the holding portion 74 of the mounting portion 71 with the engaging groove portion 47 of the outer peripheral projection portion 46 from outside the room, the mounting portion 71 of the connecting material 70 can be easily mounted from outside the room to the outer peripheral projection portion 46 of the new vertical frame member 40. By fixing the fixing portion 75 of the mounting portion 71 to the outer peripheral projection portion 46, the mounting portion 71 of the connecting material 70 can also be stably mounted to the outer peripheral projection portion 46 of the new vertical frame member 40.

[0053] When the screw 6G is attached to the screw hole 76 of the fixing portion 75, the screw 6G pushes the fixing portion 75 in a direction away from the outer peripheral projection portion 46. At that time, the movement of the fixing portion 75 is restricted by the retaining portion 74 of the mounting portion 71, which engages with the engagement groove portion 47 of the outer peripheral projection portion 46. Furthermore, by pressing the mounting portion 72 of the connecting material 70 from the outside of the room, movement of the connecting material 70 and the fixing portion 75 is easily prevented. This allows the screw 6G to be smoothly screwed into the screw hole 76, and the screw 6G can be easily attached to the screw hole 76. Therefore, the fixing portion 75 of the connecting material 70 can be easily fixed to the outer peripheral projection portion 46 of the new vertical frame member 40 using the fixing device, the screw 6G. Even when the wall surface of the building 10 is located close to the outer peripheral projection 46 of the newly installed vertical frame member 40 and the connecting material 70 is placed in the gap between the wall surface of the building 10 and the outer peripheral projection 46, the fixing work of the fixing portion 75 can be performed on the inner peripheral side of the newly installed vertical frame member 40 using the screw 6G.

[0054] The exterior material is not limited to the outer frame 64, but may be other exterior material (for example, decorative material) connected to the new vertical frame material 40 by the connecting material 70. Furthermore, the new vertical frame material 40 is not limited to a composite frame material with a composite structure having a metal frame portion 41 and a resin frame portion 42, but may be other new vertical frame material (for example, a frame material with an insulating bridge structure, a frame material made of a single member).

[0055] In the first embodiment, an example in which the present invention is applied to the new vertical frame member 40 has been described, but the present invention is not limited to the new vertical frame member 40 and can also be applied to other new frame members (for example, the new upper frame member 20). The new frame member to which the present invention is applied may be any one of the multiple new frame members provided in the new frame 3, or may be multiple new frame members. The present invention is not limited to remodeled doors and can also be applied to other remodeled fittings equipped with exterior materials.

[0056] (Second embodiment) Next, we will explain the renovated fitting 1 and the construction method for the renovated fitting 1 of the second embodiment. In the renovated fitting 1 and the construction method for the renovated fitting 1 of the second embodiment, we will omit explanations of the same matters as in the construction method for the renovated fitting 1 and the renovated fitting 1 of the first embodiment, and will mainly explain matters that differ from the construction method for the renovated fitting 1 and the renovated fitting 1 of the first embodiment. Furthermore, with regard to the renovated fitting 1 of the second embodiment, the same names and symbols as the configurations of the renovated fitting 1 of the first embodiment will be used for the components that correspond to the components of the renovated fitting 1 of the first embodiment.

[0057] Figure 10 is a cross-sectional view showing a portion of the renovated fitting 1 of the second embodiment including an existing vertical frame member 53 and a new vertical frame member 40, and similarly to Figure 4, shows one of a pair of existing vertical frame members 53 and one of a pair of new vertical frame members 40. Figure 11 is a cross-sectional view showing the pivoting door body 4 of the renovated fitting 1 of the second embodiment, and schematically shows the door body 4 in three locations that have moved due to the pivoting movement.

[0058] As shown in the figures, in the renovated fitting 1 of the second embodiment, the position of the connecting member 70 is different from the position of the connecting member 70 of the first embodiment (see FIG. 4). The connecting member 70 is arranged on the outer periphery of the new vertical frame member 40, on a position on the indoor side of the outdoor facing portion 43 of the new vertical frame member 40, and is attached to the new vertical frame member 40. The connecting member 70, attachment portion 71, and mounting portion 72 are located on the indoor side (the side of the existing vertical frame member 53) of the outdoor facing portion 43 of the new vertical frame member 40, and are arranged spaced apart from the outdoor facing portion 43 on the indoor side. At a position inside the room rather than the outside viewing portion 43 of the newly installed vertical frame material 40, the mounting portion 72 protrudes from the outer peripheral viewing portion 46 in the viewing direction F of the newly installed vertical frame material 40, and the outer frame 64 is attached to the mounting portion 72 of the connecting material 70 and is connected to the outer peripheral viewing portion 46 of the newly installed vertical frame material 40 by the connecting material 70.

[0059] The door body 4 has a decorative element 4E that protrudes toward the exterior. The decorative element 4E is a decorative component (decorative element) that decorates the door body 4 and is attached to the exterior surface of the door body 4 that faces the exterior. When the door body 4 is fully open, the decorative element 4E protrudes from the door body 4 toward the exterior frame 64 on the interior side and is positioned opposite the exterior frame 64 in the indoor-outdoor direction T. Here, the connecting element 70 connects the exterior frame 64 to the new vertical frame member 40 at a position on the interior side of the exterior visible portion 43 of the new vertical frame member 40, thereby positioning the exterior frame 64 closer to the building 10 (exterior wall surface 13). Therefore, even if the door body 4 has a protruding portion such as the decorative element 4E on the exterior side, it is possible to prevent the protruding portion of the door body 4 from hitting and interfering with the exterior frame 64 when the door body 4 is open.
