Description

Technical Field

[0001] The present invention relates to a construction method of a fitting for connecting two fitting frames through a vertical post.

Background Art

[0002] When connecting the fitting frames of two fittings such as a window frame and a door frame and installing them in a building, a vertical post may be used. In such a fitting construction method, for example, before installing the two fitting frames, the vertical post is installed at a position between the two fitting frames, and the two fitting frames are respectively attached to the vertical post. The two fitting frames are connected by the vertical post, and the two fitting frames and the vertical post are installed in the building. Further, as a fitting provided with a vertical post, conventionally, an intermediate partition panel for connecting adjacent panels through a vertical post is known (see Patent Document 1).

[0003] In the conventional intermediate partition panel described in Patent Document 1, the panel has a fitting frame including a vertical frame, and the vertical post fits into the vertical frames of two adjacent fitting frames. The protruding strip portion of the continuous window vertical post cover is inserted between the vertical frames of the two fitting frames, and the inner plane portion of the continuous window vertical post cover adheres to the outer side surface of the vertical frame, so that the fitting frame and the panel are positioned. However, in the conventional intermediate partition panel, when the vertical post is installed on the floor separated from a reference location such as a wall portion or a column of the building, it is difficult to position the vertical post. As a result, when the installation position of the vertical post is deviated from the regular installation position, there is a concern that a misalignment may occur in the installed fitting frame in a state where the vertical post is fitted between the vertical frames of the two fitting frames. Further, due to the construction errors of each of the vertical post and the two fitting frames, there is also a concern that the two fitting frames and the vertical post are installed in a state where a gap is generated between the vertical post and the fitting frame. In such a case, there may also be a problem in the appearance of the intermediate partition panel.

Figure 6A shows the first joinery frame 12 and the mullion 30 before installation into building 2, while Figures 6B, 7A, and 7B show the first joinery frame 12, the second joinery frame 22, and the mullion 30 in the intermediate stages of installation into building 2.

[0043] As shown in the diagram, when installing the joinery, before installing the first joinery frame 12 and the second joinery frame 22 into the building 2, the first joinery frame 12 is attached to the mullion 30 using the mounting fixture 42 (see Figure 3), thereby pre-connecting the mullion 30 to the first joinery frame 12 (see Figure 6A). At that time, the mullion 30 is positioned along one of the pair of vertical frames 15 and 16 of the first joinery frame 12 (here, the second vertical frame 16), and the second vertical frame 16 is attached to the mullion 30, connecting the mullion 30 to the second vertical frame 16. In addition, the engaging portion 16C of the second vertical frame 16 is engaged with the positioning portion 35 of the mullion 30, and with the second vertical frame 16 positioned relative to the mullion 30, the mullion 30 is connected to the second vertical frame 16. As a result, the mullion 30 is held in place by the second vertical frame 16 and the first joinery frame 12.

[0044] Next, the first door frame 12 and the mullion 30 are moved toward their installation positions in the building 2 (see Figure 6B). The first door frame 12 is also moved toward the door frame fixing section 2A of the building 2, and the first vertical frame 15 of the first door frame 12 is positioned along the door frame fixing section 2A (see Figure 7A). Subsequently, the first vertical frame 15 is fixed to the door frame fixing section 2A using the fixing device 40 (see Figure 2), and the first door frame 12 is fixed to the door frame fixing section 2A via the first vertical frame 15. When fixing the first door frame 12 to the door frame fixing section 2A, first the first vertical frame 15 is temporarily fixed to the door frame fixing section 2A using the fixing device 40, and then the first door frame 12 is temporarily fixed to the door frame fixing section 2A via the first vertical frame 15. In temporary fixing, the fastener 40, which is a screw, is only temporarily tightened without being fully tightened, and the first vertical frame 15 and the first door frame 12 are temporarily fixed (temporarily fastened) to the door frame fixing part 2A by the loosened fastener 40.

[0045] The first vertical frame 15 and the first door frame 12 are temporarily fixed to the door frame fixing part 2A of the building 2 in a displaceable manner. Next, the positions of the first vertical frame 15 and the first door frame 12 are adjusted with respect to the door frame fixing part 2A to position them in the installation location on the building 2. At this time, for example, an adjustment material such as a spacer is inserted between the door frame fixing part 2A and the first vertical frame 15 to adjust the distance between the door frame fixing part 2A and the first vertical frame 15. In this way, the position of the first vertical frame 15 is adjusted with respect to the door frame fixing part 2A to position the first vertical frame 15 along the vertical direction R. Subsequently, the first vertical frame 15 is permanently fixed to the door frame fixing part 2A with the fixing device 40, and the first door frame 12 is permanently fixed to the door frame fixing part 2A via the first vertical frame 15. In this final fixing process, the fastener 40 is tightened to complete the final fixing, and the first vertical frame 15 and the first door frame 12, whose positions have been adjusted, are permanently fixed (final fixing) to the door frame fixing part 2A using the fastener 40.

[0046] Next, the mullion 30 is positioned relative to the first joinery frame 12, and placed in its installation location on the building 2. This positions the mullion 30 relative to the building 2, including the floor 2B. At this time, for example, the position of the mullion 30 in the left-right direction S and the depth direction T is adjusted and determined based on the dimensions (length) of the horizontal frame 14 of the first joinery frame 12 and the first vertical frame 15 positioned along the vertical direction R. The mullion 30 is also moved together with the second vertical frame 16 to adjust its position, including its inclination. In this way, the position of the mullion 30 is adjusted relative to the first joinery frame 12, positioning the mullion 30 in its installation location and arranging it along the vertical direction R.

[0047] Next, the positioned mullion 30 is fixed to the building 2 with a fixing member 50 (see Figure 3). The fixing member 50 is attached to the mullion 30 and the floor portion 2B of the building 2 inside the recess 38 of the mullion 30. The mullion 30 is fixed to the floor portion 2B of the building 2 by the fixing member 50 and held in place in the installation position on the building 2. Subsequently, the second door frame 22 is moved toward the installation position on the building 2 (see Figure 7B). The second door frame 22 is also moved toward the mullion 30 so that the first vertical frame 26 of the second door frame 22 is positioned along the mullion 30. In this state, the positions of the first vertical frame 26 and the second door frame 22 are adjusted with respect to the mullion 30 to position the first vertical frame 26 and the second door frame 22 in the installation position on the building 2.

[0048] Next, the second door frame 22 is attached to the mullion 30 using the mounting bracket 43, connecting the mullion 30 to the second door frame 22. At this time, the first vertical frame 26 of the second door frame 22 is positioned along the mullion 30, the first vertical frame 26 is attached to the mullion 30, and the mullion 30 is connected to the first vertical frame 26. The second door frame 22 is connected to the first door frame 12 by the mullion 30, connecting the first door frame 12 and the second door frame 22 via the mullion 30. In addition, the first door frame 12 is fixed to the ceiling 2C of the building 2, and the second door frame 22 is fixed to the floor 2B, ceiling 2C, and wall 2D of the building 2. In this way, the first door frame 12, the second door frame 22, and the mullion 30 are installed in the building 2. In building 2, the second joinery frame 22 attached to the mullion 30 covers and shields the fixing material 50 for securing the mullion 30.

[0049] In the joinery installation method described above, by using the first joinery frame 12 as a reference, the mullion 30 connecting the two joinery frames 12 and 22 can be easily positioned, and the two joinery frames 12 and 22 and the mullion 30 can be installed accurately in the building 2. Furthermore, by adjusting the position of the temporarily fixed first joinery frame 12 using the joinery frame fixing part 2A as a reference, the first joinery frame 12 is permanently fixed to the joinery frame fixing part 2A, and the first joinery frame 12 can be installed accurately in the building 2.

[0050] The mullion 30 is positioned along the second vertical frame 16 of the first joinery frame 12 and connected to the second vertical frame 16, thereby preventing gaps from forming between the mullion 30 and the second vertical frame 16, and enabling the mullion 30 and the second vertical frame 16 to be installed in the building 2 with high precision. By engaging the engaging portion 16C of the second vertical frame 16 with the positioning portion 35 of the mullion 30, the second vertical frame 16 can be easily positioned relative to the mullion 30, and the mullion 30 can be accurately connected to the second vertical frame 16. The fixing material 50 is shielded by the second joinery frame 22, preventing exposure of the fixing material 50 and improving the aesthetic appearance of the mullion 30 in the connecting joinery 1.

[0051] Furthermore, the first door frame 12 and the second door frame 22 are not limited to the examples in the first embodiment, and can be implemented as various door frames. For example, the first door frame 12 may be a door frame configured in the same way as the second door frame 22, or it may be a door frame having upper and lower horizontal frames and a pair of vertical frames. Also, the second door frame 22 may be a door frame without vertical members 28 and horizontal members 29, or it may be a door frame configured in the same way as the first door frame 12. The mullion 30 may be fixed to either the floor 2B or the ceiling 2C of the building 2 by the fixing member 50, or it may be fixed to both the floor 2B and the ceiling 2C of the building 2.

[0052] Next, the installation method for joinery according to other embodiments will be described. In the following installation methods for joinery, the same matters as in the installation method for joinery of the first embodiment will be omitted, and the differences from the installation method for joinery of the first embodiment will be mainly described. Furthermore, with respect to the following installation methods for joinery, the same names and reference numerals as those used in the installation method for joinery of the first embodiment will be used for components corresponding to the components of the installation method for joinery of the first embodiment.

[0053] (Second Embodiment) Figure 8 is a cross-sectional view showing the connecting joinery 1 of the second embodiment, and, similar to Figure 2, shows the connecting joinery 1 cut along the horizontal plane.

[0054] As shown in the figure, in the connecting joinery 1 of the second embodiment, the mullion 30 differs from the mullion 30 of the first embodiment. The mullion 30 does not have the first projection 33 of the mullion 30 of the first embodiment and does not form the mounting groove portion 30A of the mullion 30 of the first embodiment. The second vertical frame 16 of the first joinery frame 12 is attached to the mullion 30 by contacting the first side portion 31 and the second projection 34 of the mullion 30. The recess 38 of the mullion 30 is formed in a concave shape between the first side portion 31 and the second side portion 32 and is provided on one side of the mullion 30 in the depth direction T (the visible portion of the mullion 30). The recess 38 opens at the visible portion of the mullion 30 and is open toward one side in the depth direction T. The fixing member 50 is positioned inside the recess 38 of the mullion 30 and is located between the first side portion 31 and the second side portion 32 of the mullion 30.

[0055] The connecting joinery 1 includes a cover 60 attached to the mullion 30. The cover 60 extends in the longitudinal direction of the mullion 30 and is fitted into and locked in a recess 38 of the mullion 30. The cover 60 is attached to the recess 38 and the mullion 30, closing the opening of the recess 38 and forming a storage space 61 between the recess 38 and the cover 60. The fixing member 50 is positioned inside the storage space 61, which is a void, and is housed in the storage space 61. In this state, the fixing member 50 is positioned in the area of ​​the mullion 30 that is covered by the cover 60 (inside the recess 38), and is located between the recess 38 of the mullion 30 and the cover 60.

[0056] The cover 60 covers the recess 38 and the fixing member 50 on one side of the mullion 30 in the depth direction T, shielding and concealing the recess 38 and the fixing member 50. The mounting pieces 51 and 52 of the fixing member 50 and the head of the mounting fixture 44 are positioned inside the recess 38 and are covered and shielded by the cover 60. During the installation of the joinery, after fixing the positioned mullion 30 to the building 2 with the fixing member 50, the cover 60 is attached to the recess 38 and the mullion 30, and the fixing member 50 is covered and shielded by the cover 60. Therefore, the cover 60 prevents the fixing member 50 from being exposed, improving the aesthetic appearance of the mullion 30 in the connecting joinery 1.
