[0016] As described above, the fire prevention equipment of this embodiment is configured such that the left and right sliding windows 2, 3, which are fire-resistant fittings, are connected by a vertical member 1 equipped with mounting steel, and the indoor and outdoor sides of the connecting parts of the sliding windows 2, 3 are covered by an indoor side member 7 and an outdoor side cover 112, thereby forming a fitting with fire-resistant performance as a whole. The structure of the connection portion of the vertical members 1 between the vertical frames 23, 34 of the left and right sliding windows 2, 3 will be further explained below.

[0017] (Vertical frame connection structure using vertical members) The interior-side mounting steel member 111 constituting the mullion 11 is formed by connecting two U-shaped steel members facing each other and by welding or screwing, etc., as shown in Figures 4 and 5, and is a long member with a rectangular cross-section and hollow shape. The manufacturing method of the interior-side mounting steel member 111 is not limited. The interior side mounting steel material 111 has bolt through holes 111a formed at appropriate positions in the vertical direction, penetrating in the prospective direction. In FIG. 4, fastening means such as screws for fastening the interior side member 7 to the vertical member 1 are omitted.

[0018] As shown in Figures 4 and 5, the outdoor cover 112 that constitutes the upright 11 has an outdoor appearance wall (cover wall) 112a, a hollow main body portion 112b with a hollow cross-section that protrudes toward the room from the indoor side of the outdoor appearance wall 112a, and protrusions 112c, 112c extending in the left and right directions from the left and right side surfaces of the hollow main body portion 112b.

[0019] In this embodiment, the outdoor cover 112 is formed from an indoor portion having a hollow main body portion 112b with a width dimension smaller than the left and right width dimensions of the indoor side mounting steel material 111, and an outdoor portion having a width dimension larger than the left and right width dimensions of the indoor side mounting steel material 111, and the protrusion pieces 112c are provided on the left and right side surfaces of the outdoor portion.

[0020] The outdoor cover 112 has tension material mounting grooves 112d, 112d provided along the longitudinal direction on the indoor side of the outdoor visible wall 112a at a portion extending to the left and right beyond the hollow main body portion 112b, and tension material s112, s112 is attached to the tension material mounting grooves 112d, 112d. The exterior cover 112 is provided with bolt holes 112e in the interior wall of the hollow main body portion 112b into which bolts b2 are screwed.

[0021] The outdoor cover 112 is placed on the outdoor side of the indoor mounting steel material 111 so that the hollow main body portion 112b is positioned on the outdoor side of the indoor mounting steel material 111, and is attached to the indoor mounting steel material 111 by screwing a bolt b2 that passes through the bolt through hole 111a from the indoor side of the indoor mounting steel material 111 into a bolt hole 112e provided in the hollow main body portion 112b of the outdoor cover 112.

[0022] As shown in Figures 4 and 5, the through anchor 12 has a concealed wall 12a, an indoor side mounting portion 12b where the indoor side end of the concealed wall 12a is bent toward the vertical frame and continues, and an outdoor side mounting portion 12c where the outdoor side end of the concealed wall 12a is bent toward the vertical frame and continues, and is a long member having approximately the same length dimension as the indoor side mounting steel material 111.

[0023] The left and right through anchors 12, 12 are abutted against the left and right visible walls of the indoor mounting steel material 111 at the indoor side of the visible walls 12a, 12a and fixed with screws b3, b3, and the outdoor side portions of the through anchors 12, 12 extend further outside the room than the indoor side mounting steel material 111.

[0024] The vertical frames 23, 34 of the left and right sliding windows 2, 3 have front walls 23a, 34a, interior front walls 23b, 34b, and exterior front walls 23c, 34c, with bent pieces 23d, 34d bent toward the outside of the room being provided on the outer periphery of the interior front walls 23b, 34b, and bent pieces 23e, 34e bent toward the inside of the room being provided on the outer periphery of the exterior front walls 23c, 34c.

[0025] The vertical frames 23, 34 are arranged on the opposite side of the left and right through anchors 12, 12, and on the inside of the room, the inside visible wall 23b, 34b is abutted against the inside mounting portions 12b, 12b of the through anchors 12, 12 from the outside of the room, and is fixed from the inside of the room with screws b4. In addition, on the outside of the room, the vertical frames 23, 34 have the outside bent pieces 23e, 34e abutting the outside mounting portions 12c, 12c of the through anchors 12, 12 from the outside of the room, and the outside visible walls 23c, 34c are fixed to the outside mounting portions 12c, 12c with screws b5.

[0026] The vertical member 1 to which the left and right vertical frames 23, 34 are attached is arranged such that the indoor side portion of the hollow main body portion 112b of the outdoor cover 112 is positioned between the left and right through anchors 12, 12 extending toward the outdoor side from the indoor side mounting steel material 111, and the outdoor side portion of the hollow main body portion 112b is positioned outside the outdoor side of the through anchors 12, 12, and is arranged between the outdoor side visible walls 23c, 34c of the left and right vertical frames 23, 34.

[0027] At this time, gaps (play) are provided between the indoor side portion of the hollow main body portion 112b of the outdoor cover 112 and the left and right through anchors 12, 12, and between the outdoor side portion of the hollow main body portion 112b and the left and right vertical frames 23, 34.

[0028] The vertical member 1 connecting the left and right vertical frames 23, 34 has protrusions 112c, 112c provided on the outside part of the outside cover 112 abutting or press against the outside surfaces of the outside visible walls 23c, 34c of the left and right vertical frames 23, 34 so that they overlap, and the tight materials s112, s112 provided on the indoor side of the outside visible wall 112a are pressed against the outside surfaces of the outside visible walls 23c, 34c of the vertical frames 23, 34.

[0029] (Procedure for connecting windows with vertical members) An example of a construction procedure for the connection between the left and right sliding windows of the fire prevention equipment of this embodiment will be described with reference to the drawings. As shown in Figure 6 (a), prior to connecting the left and right vertical frames 23, 34, the through anchors 12, 12 are fixed to the left and right side surfaces of the interior mounting steel material 111 of the upright 11. The left and right through anchors 12, 12 have their blind walls 12a, 12a fixed to the left and right blind walls of the interior mounting steel material 111 with screws b3, b3, and the exterior parts extend further outside than the interior mounting steel material 111. Then, the left and right vertical frames 23, 34 are brought close from the outside of the room to the through anchors 12, 12 fixed to the inside mounting steel material 111 (arrow x1) and placed on the left and right of the vertical material 1.

[0030] As shown in Figure 6 (b), the left and right vertical frames 23, 34 arranged on the left and right of the vertical member 1 have their indoor side visible walls 23b, 34b abutting against the outdoor side surfaces of the indoor side mounting portions 12b, 12b of the through anchors 12, 12, and their outdoor side bent pieces 23e, 34e abutting against the outdoor side surfaces of the outdoor side mounting portions 12c, 12c of the through anchor 12.

[0031] Then, the indoor side mounting portions 12b, 12b of the through anchor 12 and the indoor side visible walls 23b, 34b of the vertical frames 23, 34 are fixed from the indoor side with screws b4, and the outdoor side mounting portions 12c, 12c of the through anchor 12 and the outdoor side visible walls 23c, 34c of the vertical frames 23, 34 are fixed from the outdoor side with screws b5.

[0032] Next, as shown in FIG. 7(a), the outdoor cover 112 is attached from the outdoor side to the indoor side mounting steel material 111 and the through anchors 12, 12 to which the vertical frames 23, 34 are fixed on the left and right (arrow x2). At this time, the outdoor cover 112 is installed so that the indoor side portion of the hollow main body portion 112b is inserted between the front walls 12a, 12a of the left and right through anchors 12, 12, and the outdoor side portion is inserted between the outdoor side front walls 23c, 34c of the left and right vertical frames 23, 34.

[0033] In the outdoor cover 112, in which the hollow main body portion 112b is inserted between the left and right through anchors 12, 12 and the outdoor exterior facing walls 23c, 34c of the left and right vertical frames 23, 34, as shown in Figure 7 (b), the tight materials s112, s112 provided on the indoor side of the outdoor exterior facing wall (cover wall) 112a abut against the outdoor exterior faces of the outdoor exterior facing walls 23c, 34c of the left and right vertical frames 23, 34.

[0034] Then, bolt b2 is inserted from the inside of the room through the bolt through hole 111a of the inside mounting steel material 111 (arrow x3) and screwed into the bolt hole 112e in the inside wall of the hollow main body portion 112b of the outside cover 112, and the outside cover 112 is pulled toward the inside mounting steel material 111 and attached.

[0035] When the exterior cover 112 is pulled toward the inside of the room, the protrusions 112c, 112c on the left and right sides of the hollow main body 112b abut against the exterior visible walls 23c, 34c of the left and right vertical frames 23, 34 so that they overlap from the outside of the room, restricting further movement toward the inside of the room and positioning it in the forward direction.

[0036] At this time, gaps (play) are provided between the outdoor cover 112 and the through anchors 12,12 and the left and right vertical frames 23,34, and the protrusions 112c,112c abut against the outdoor exterior visible walls 23c,34c of the vertical frames 23,34 so as to overlap from the outside of the room. Therefore, even if there are manufacturing errors in the outdoor cover 112 or the vertical frames 23,34, the errors can be absorbed by the degree of overlap between the protrusion 112c and the vertical frames 23,34, and the left-right position of the vertical frames 23,34 can be adjusted within the width of the protrusion 112c, so that the gap between the protrusion 112c and the outdoor exterior visible walls 23c,34c of the vertical frames 23,34 can be reliably sealed.

[0037] With the exterior cover 112 positioned in the forward direction by the protrusion 112c, the watertight material s112 provided on the interior side is crushed and pressed in an appropriate manner against the exterior sides of the exterior visible walls 23c, 34c of the left and right vertical frames 23, 34, maintaining a watertight condition on the exterior side of the connecting parts of the vertical frames 23, 34.

[0038] Thereafter, the indoor side component 7 is attached to the indoor side of the connecting portion of the left and right vertical frames 23, 34 using fixing means such as screws, completing the installation. An example of the construction procedure for the connection portion of the left and right sliding windows of the fire prevention equipment of this embodiment has been described above.

[0039] (Effect of the fire prevention equipment of the embodiment) As described above, in the fire prevention equipment of this embodiment, the vertical frames 23, 34 of the left and right windows 2, 3 are connected via the steel indoor mounting steel material 111 and the through anchors 12, 12, so that the left and right windows 2, 3 can be firmly connected. In the fire prevention equipment of this embodiment, the entire length between the vertical frames 23, 34 of the left and right windows 2, 3 is sealed by the steel indoor mounting material 111 and the through anchors 12, 12, so that no gaps connecting the indoors and outdoors are created between the left and right windows 2, 3 in the event of a fire, thereby improving fire prevention performance.

[0040] In the fire prevention equipment of this embodiment, the outdoor side of the vertical frames 23, 34 of the left and right windows 2, 3 are covered by an outdoor cover 112, and since the protrusions 112c on the outdoor cover 112 abut against the outdoor sides of the vertical frames 23, 34, no gaps are created between the vertical frames 23, 34 and the outdoor cover 112, thereby preventing the intrusion of flames from outside and improving fire prevention performance.

[0041] In the fire prevention equipment of this embodiment, the outdoor-side connecting parts of the vertical frames 23, 34 of the left and right windows 2, 3 are covered with an outdoor-side cover 112 equipped with a dry-tight material, and the outdoor-side cover 112 is pulled toward the inside of the room and fixed to the indoor-side mounting steel material 111, thereby pressing the dry-tight material against the vertical frames 23, 34 to make it watertight. Therefore, by fixing the outdoor-side cover 112, watertightness of the vertical frames 23, 34 can be ensured, and watertight performance can be improved with simple construction.

[0042] In the fire protection equipment of this embodiment, the protrusion 112c on the exterior cover 112 abuts against the exterior surfaces of the vertical frames 23, 34, allowing the exterior cover 112 to be positioned in the forward direction, and the dry watertight material can be pressed against the vertical frames 23, 34 in an optimal condition, thereby improving fire protection performance and watertightness with simple construction.

[0043] (Other embodiments) The shapes and configurations of the members constituting the fire protection system of the present invention are not limited to those of the above-described embodiment. For example, the cross-sectional shapes of the indoor side mounting steel material 111, the outdoor side cover 112, and the through anchors 12, 12 may be changed to match the shape and configuration of the outer periphery of the left and right vertical frames 23, 34.

[0044] As shown in Figure 8, the vertical frames 23, 34 of the fire protection equipment of this embodiment have projection walls 23a, 34a, indoor side projection walls 23b, 34b, and outdoor side projection walls 23c, 34c, and bent pieces 23d, 34d bent toward the outside are provided at the outer peripheral ends of the indoor side projection walls 23b, 34b. The vertical frames 23, 34 of this embodiment differ from the vertical frames 23, 34 of the previous embodiment in that the exterior sight walls 23c, 34c extend more toward the outer periphery than the interior sight walls 23b, 34b, and bent pieces 23e, 34e are provided at the outer periphery ends of the exterior sight walls 23c, 34c, which are bent toward the room and then bent further toward the outer periphery.

[0045] The through anchor 12 in this embodiment may be a long member having a projection wall 12a, an indoor side mounting portion 12b where the indoor side end of the projection wall 12a is bent toward the vertical frame and continues, and an outdoor side mounting portion 12c where the outdoor side end of the projection wall 12a is bent toward the opposite vertical frame and continues, in accordance with the shape of the outer periphery of the vertical frames 23, 34.

[0046] In addition, the outdoor cover 112 may have a T-shaped hollow portion overall, with an indoor portion having a width dimension smaller than the spacing between the outdoor mounting portions 12c, 12c of the through anchor 12 whose hollow main body portion 112b is fixed to the indoor mounting steel material 111, and an outdoor portion having a width dimension larger than that, in accordance with the shape of the through anchor 12 and the vertical frames 23, 34.

[0047] In addition, it goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
