[0030] The internal cover 14 is positioned on the indoor side of the upright 11 and is fixed to the mounting steel material 111 by screw b7 at the left-right central position of the indoor side cover part 14a, and is fixed to the vertical frames 23, 34 and the vertical frame connecting materials 12, 12 by screws b8, b8 at the left and right positions of the indoor side cover part 14a.

[0031] An external cover 13 is attached to the exterior side of the upright 11, and an internal cover 14 is attached to the interior side of the upright 11, so that the left and right vertical frames 23, 34 attached to the left and right sides of the upright 11 so as to be movable in the forward direction are clamped from inside and outside the room and positioned at the optimal position in the forward direction and attached to the vertical member 1.

[0032] The vertical frames 23, 34 attached to the vertical member 1 have the protrusions 13d, 13e of the external cover 13 abutting or press-contacting the outdoor side surfaces of the outdoor side visible walls 23c, 34c from the outside of the room, and the tight materials s13, s13 provided on the indoor side of the cover wall 13a of the external cover 13 are press-contacting the outdoor side surfaces of the outdoor side visible walls 23c, 34c.

[0033] (Manufacturing method of connecting equipment) An example of a method for manufacturing the fire protection equipment of this embodiment will be described with reference to the drawings. The mounting steel material 111 is fixed to a pair of vertical mounting members 5, 5 fixed to the opening A with screws b1, b1 (see Figures 2 and 3), and an external cover mounting material 112 is fixed to the outdoor side wall with screws b2, as shown in Figure 6 (a). In addition, the fire prevention equipment can be installed to the opening A by fixing the sliding windows 2, 3 to the left and right sides of the vertical member 1 to form a continuous window, and then welding the vertical member mounting members 5, 5 fixed to the mounting steel material 111 with screws b1, b1 to a steel material etc. fixed to the main body.Alternatively, the mounting steel material 111 etc. can be attached to the opening A at a stage before forming the continuous window, and then the sliding windows 2, 3 can be fixed to the left and right sides of the vertical member 1 to form a continuous window.The timing of fixing the vertical member 1 or the continuous window to the opening A is not limited.

[0034] Step 1: Attach the left and right vertical frame connectors 12, 12 to the upright 11 using screws b3, b3. The left and right vertical frame connecting members 12, 12 are arranged on the left and right sides of the mounting steel member 111 of the upright 11 so that the projecting walls 12a of the vertical frame connecting members 12 abut against the left and right side surfaces of the mounting steel member 111, and are fastened from the left and right sides with screws b3, b3 through the long holes 12d, 12d, so that the members are attached so as to be movable in the projecting direction.

[0035] Step 2: The left and right vertical frames 23, 34 are attached to the left and right vertical frame connectors 12, 12 attached to the left and right sides of the upright 11. The left and right vertical frames 23, 34 are placed on the left and right positions of the left and right vertical frame connectors 12, 12 attached to the left and right of the upright 11. At this time, as shown in Figure 6 (b), the room-side visible walls 23b, 34b of the left and right vertical frames 23, 34 abut the room-side surfaces of the room-side mounting parts 12b, 12b of the vertical frame connectors 12, 12, and the room-side bent pieces 23e, 34e of the left and right vertical frames 23, 34 abut the room-side surfaces of the room-side mounting parts 12c, 12c of the vertical frame connectors 12, 12.

[0036] Then, the indoor side mounting portions 12b, 12b of the left and right vertical frame connecting members 12, 12 and the indoor side visible walls 23b, 34b of the vertical frames 23, 34 are screwed from the indoor side with screws b4, and the outdoor side mounting portions 12c, 12c of the left and right vertical frame connecting members 12, 12 and the outdoor side visible walls 23c, 34c of the vertical frames 23, 34 are screwed from the outdoor side with screws b5, thereby attaching the left and right vertical frames 23, 34 to the vertical frame connecting members 12, 12. At this time, since the external cover 13 is not attached to the upright 11, the left and right vertical frames 23, 34 can be easily fastened to the vertical frame connecting members 12, 12 with screws, etc.

[0037] Step 3: Attach the external cover 13 to the outside of the post 11. As shown in Figure 7(a), the vertical frame connecting materials 12, 12 and the vertical frames 23, 34 are moved toward the room relative to the mounting steel material 111 (arrow x1) so that the screw b3 used to attach the vertical frame connecting material 12 is positioned on the outside of the long hole 12d provided in the concealed wall 12a of the vertical frame connecting material 12, and the external cover mounting material 112 protrudes outside the room further than the left and right vertical frame connecting materials 12, 12.

[0038] As shown in Figure 7 (b), the engaging portions 13f, 13g of the external cover 13 are engaged with the engaging portions 112d, 112e of the external cover mounting material 112 protruding to the outside of the room of the left and right vertical frame connecting materials 12, 12, and the left concealed wall 112c of the external cover mounting material 112 and the left concealed wall 13c of the external cover 13 are screwed together with screw b6 to fix the external cover 13 to the outside of the upright 11.

[0039] Step 4: The left and right vertical frame connecting members 12, 12 are moved to the outside of the room, and the outside facing surfaces of the outside facing walls 23c, 34c of the vertical frames 23, 34 are abutted against the protrusions 13d, 13e of the external cover 13. As shown in Figure 8 (a), the vertical frame connecting materials 12, 12 and the vertical frames 23, 34 are moved toward the outside relative to the mounting steel material 111 (arrow x2) so that the screw b3 attaching the vertical frame connecting material 12 is positioned on the inside of the long hole 12d provided in the visible wall 12a of the vertical frame connecting material 12, and the outside visible surfaces of the outside visible walls 23c, 34c of the left and right vertical frames 23, 34 are abutted against the protrusions 13d, 13e provided on the inside of the cover wall 13a of the external cover 13.

[0040] At this time, by abutting the protrusions 13d, 13e of the external cover 13 against the visible surfaces of the outdoor side visible walls 23c, 34c of the vertical frames 23, 34 from the outside of the room, the protrusions 13d, 13e can be abutted against the visible surfaces of the outdoor side visible walls 23c, 34c of the vertical frames 23, 34 even if there are manufacturing errors in the external cover 13 or the vertical frames 23, 34.In addition, the left-right position of the vertical frames 23, 34 can be adjusted within the width of the protrusions 13d, 13e, so that the gap between the protrusions 13d, 13e and the outdoor side visible walls 23c, 34c of the vertical frames 23, 34 can be reliably sealed.

[0041] Step 5: Fix the inner cover 14 to the indoor side of the post 11. The internal cover 14 is brought closer from the inside of the room (arrow x3) to the upright 11, which has vertical frames 23, 34 attached to the left and right, and the indoor side cover part 14a of the internal cover 14 is screwed to the indoor side wall of the upright 11 with screws b7, so that the left and right vertical frames 23, 34 are sandwiched between the external cover 13 and the internal cover 14, as shown in Figure 8 (b). Finally, the indoor side cover portion 14a of the internal cover 14 is fixed to the indoor side mounting portions 12b, 12b of the left and right vertical frame connecting members 12, 12 and the indoor side visible walls 23b, 34b of the vertical frames 23, 34 with screws b8.

[0042] The left and right vertical frames 23, 34 are clamped between the external cover 13 and the internal cover 14, so that the exterior visible walls 23c, 34c abut against the protrusions 13d, 13e of the external cover 13 and are positioned in the forward direction, and the tight materials s13, s13 provided on the interior side of the cover wall 13a of the external cover 13 are crushed in an appropriate state and pressed against the exterior visible surfaces of the exterior visible walls 23c, 34c of the left and right vertical frames 23, 34. An example of the procedure for the manufacturing method for one vertical member of the fire protection system of this embodiment has been described above.

[0043] -Second embodiment- The connecting structure of the vertical frames in the connecting equipment of the second embodiment will be described with reference to Figs. In addition, the same components as those in the connection facility of the first embodiment are denoted by the same reference numerals in the drawings, and some of the description will be omitted.

As shown in Figure 12(a), a mounting steel material 111 is fixed to a pair of vertical mounting members 5, 5 fixed to the opening A with screws b1, b1, and an external cover mounting material 112 is fixed to the outdoor side wall with screws b2.

[0060] Step 1: Attach the left and right vertical frame connectors 12, 12 to the upright 11 fixed to the opening A using screws b3, b3. The left and right vertical frame connecting members 12, 12 are positioned on the left and right side surfaces of the mounting steel member 111 of the upright 11 so that their projecting walls 12a, 12a abut, and are fastened from the left and right using screws b3, b3 through the long holes 12d, 12d, so that the members are attached so that they can be moved in the projecting direction.

[0061] Step 2: Attach the left and right vertical frames 23, 34 to the left and right vertical frame connectors 12, 12 attached to the left and right sides of the upright 11. As shown in Figure 12 (b), left and right vertical frames 23, 34 are placed on the left and right positions of the left and right vertical frame connecting members 12, 12 attached to the left and right sides of the upright 11, and the indoor side mounting portions 12b, 12b of the left and right vertical frame connecting members 12, 12 and the indoor side visible walls 23b, 34b of the vertical frames 23, 34 are screwed from the indoor side with screws b4, and the outdoor side mounting portions 12c, 12c of the left and right vertical frame connecting members 12, 12 and the outdoor side visible walls 23c, 34c of the vertical frames 23, 34 are screwed from the outdoor side with screws b5, thereby attaching the left and right vertical frames 23, 34 to the vertical frame connecting members 12, 12.

[0062] Step 3: Attach the external cover 13 to the outside of the post 11. As shown in Figure 13(a), the vertical frame connecting material 12 and the vertical frames 23, 34 are moved toward the room relative to the mounting steel material 111 (arrow x1) so that the screw b3 used to attach the vertical frame connecting material 12 is positioned on the outside of the long hole 12d provided in the concealed wall 12a of the vertical frame connecting material 12, and the external cover mounting material 112 protrudes outside the room further than the left and right vertical frame connecting materials 12, 12.

[0063] As shown in Figure 13 (b), the engaging portions 13f, 13g of the external cover 13 are engaged with the engaging portions 112d, 112e of the external cover mounting material 112 protruding to the outside of the room of the left and right vertical frame connecting materials 12, 12, and the concealed wall 112b of the external cover mounting material 112 and the concealed wall 13b of the external cover 13 are screwed together with screws b6 to fix the external cover 13 to the outside of the upright 11.

[0064] Step 4: The left and right vertical frame connecting members are moved to the outside of the room, and the outside facing surfaces of the outside facing walls 23c, 34c of the vertical frames 23, 34 are abutted against the protrusions 13d, 13e of the external cover 13. As shown in Figure 14(a), the vertical frame connecting material 12 and the vertical frames 23, 34 are moved toward the outside relative to the mounting steel material 111 (arrow x2) so that the screw b3 attaching the vertical frame connecting material 12 is positioned on the inside of the long hole 12d provided in the visible wall 12a of the vertical frame connecting material 12, and the outside visible surfaces of the outside visible walls 23c, 34c of the left and right vertical frames 23, 34 are abutted against the protrusions 13d, 13e provided on the inside of the cover wall 13a of the external cover 13.

[0065] Step 5: Fix the inner cover 14 to the indoor side of the post 11. The internal cover 14 is brought closer from the inside of the room (arrow x3) to the upright 11, which has vertical frames 23, 34 attached to the left and right, and the indoor side cover part 14a of the internal cover 14 is screwed to the indoor side wall of the upright 11 with screws b7, so that the left and right vertical frames 23, 34 are sandwiched between the external cover 13 and the internal cover 14, as shown in Figure 14(b). Finally, the indoor side cover portion 14a of the internal cover 14 is fixed to the indoor side mounting portions 12b, 12b of the left and right vertical frame connecting members 12, 12 and the indoor side visible walls 23b, 34b of the vertical frames 23, 34 with screws b8. An example of the procedure for the manufacturing method of one vertical member of the connecting equipment according to the second embodiment has been described above.

[0066] (Effect of the fire prevention equipment of the embodiment) As described above, in the connecting equipment of the embodiment, the vertical frames 23, 34 of the left and right windows 2, 3 are connected via steel mounting materials 111 and left and right vertical frame connecting materials 12, 12, so that the left and right windows 2, 3 can be firmly connected. In addition, since the left and right vertical frame connecting members 12, 12 are fixed to the mounting steel member 111 with screws, no techniques such as welding are required to fix the vertical frame connecting members 12, and by making the mounting holes long holes, the position can be adjusted, improving workability. In the connecting equipment of this embodiment, the space between the vertical frames 23, 34 of the left and right windows 2, 3 is blocked along the entire length by the steel mounting material 111 and the left and right vertical frame connecting materials 12, 12, so that no gaps are created between the left and right windows 2, 3 that would connect the inside and outside of the room in the event of a fire, improving fire prevention performance.

[0067] In the connecting equipment of this embodiment, the outdoor sides of the vertical frames 23, 34 of the left and right windows 2, 3 are covered by an external cover 13, and the protrusions 13d, 13e on the external cover 13 abut the outdoor facing surfaces of the vertical frames 23, 34, so that no gaps are created between the vertical frames 23, 34 and the external cover 13, preventing the intrusion of flames from outside and improving fire resistance.

[0068] In the connecting equipment of this embodiment, the outdoor connecting portion of the vertical frames 23, 34 of the left and right windows 2, 3 is covered with an external cover 13 provided with a dry watertight material s13, and the vertical frames 23, 34 are sandwiched between the internal cover 14 and the external cover 13 to press the dry watertight materials s13, s13 against the vertical frames 23, 34, thereby making the equipment watertight, thereby improving watertightness performance with simple construction.

[0069] In the connecting equipment of this embodiment, the protrusions 13d, 13e on the external cover 13 abut against the outdoor facing surfaces of the vertical frames 23, 34 from the outside of the room, thereby enabling the external cover 13 to be positioned in the forward direction, and the dry watertight material s13 can be pressed against the vertical frames 23, 34 in an optimal condition, thereby improving fire resistance and watertightness through simple construction.

[0070] In the connecting equipment of this embodiment, the external cover 13 is attached after the vertical frames 23, 34 are attached to the uprights 11, so that the external cover 13 does not get in the way when attaching the vertical frames 23, 34, improving workability.

[0071] The shapes and configurations of the members constituting the connection facility of the present invention are not limited to those of the above-described embodiment. In other words, the cross-sectional shape and configuration of the mounting steel material 111 of the upright 11 and the external cover mounting material 112, the vertical frame connecting material 12, the external cover 13, and the internal cover 14 may be changed to match the shape and configuration of the outer periphery of the left and right vertical frames 23, 34.

[0072] Although the first and second embodiments of the connecting equipment have been described above, it goes without saying that these do not limit the invention described in the claims and are to be treated as examples. [Explanation of symbols]
