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 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 indoor side mounting steel material 111 has bolt through holes 111a that penetrate in the prospective direction at appropriate positions in the vertical direction.
[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 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-right direction from the left and right side surfaces of the main body portion 112b.
[0019] In this embodiment, the outdoor cover 112 is formed from an indoor portion having a small width dimension in the main body 112b and an outdoor portion having a larger width dimension than the indoor portion, and the protrusions 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 left and right beyond the 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 a bolt hole 112e in the interior wall of the main body 112b into which the bolt b2 is screwed.
[0021] The exterior cover 112 is placed on the exterior side of the interior mounting steel material 111, and is attached to the interior mounting steel material 111 by screwing a bolt b2 that passes through the bolt through hole 111a from the interior side of the interior mounting steel material 111 into a bolt hole 112e provided in the main body 112b of the exterior 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 opposite 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 fixed with screws b3, b3 by abutting the concealed walls 12a, 12a against the left and right concealed walls of the indoor side mounting steel material 111, 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 concealed walls 23a, 34a, interior concealed walls 23b, 34b, and exterior concealed walls 23c, 34c, and bent pieces 23d, 34d bent toward the outside are provided at the outer peripheral ends of the interior concealed walls 23b, 34b. In addition, the vertical frames 23, 34 have exterior sight walls 23c, 34c that extend further outward than the interior sight walls 23b, 34b, and are provided with bent pieces 23e, 34e at the outer periphery of the exterior sight walls 23c, 34c that are bent toward the inside of the room and then bent further outward.
[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 fixed with screws b4, b4. In addition, the vertical frames 23, 34 are connected from the outside of the room by screws b5, b5 with the outside-side bent pieces 23e, 34e abutting the outside-side mounting portions 12c, 12c of the through anchors 12, 12 from the outside of the room.
[0026] The vertical member 1 to which the left and right vertical frames 23, 34 are attached is arranged so that the indoor side portion of the main body 112b of the outdoor cover 112 is positioned between the left and right through anchors 12, 12 extending from the indoor side mounting steel material 111 to the outdoor side, and the outdoor side portion of the main body 112b is positioned on 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 main body 112b of the outdoor cover 112 and the left and right through anchors 12, 12, and between the outdoor side portion of the main body 112b and the left and right vertical frames 23, .
[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] (Steps for connecting windows using 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 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 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 bent pieces 23e, 34e 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 portion of the main body 112b is inserted between the outdoor mounting portions 12c, 12c of the left and right through anchors 12, 12, and the outdoor portion is inserted between the outdoor visible walls 23c, 34c of the left and right vertical frames 23, 34.
[0033] As shown in Figure 7(b), the exterior cover 112 with the main body 112b inserted between the left and right through anchors 12, 12 and the exterior facing walls 23c, 34c of the left and right vertical frames 23, 34 has the weatherstripping materials s112, s112 provided on the indoor side of the exterior facing wall (cover wall) 112a abutting the exterior side of the 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 main body 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 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 the outer periphery of the indoor side projection walls 23b, 34b is provided with bent pieces 23d, 34d that bend toward the outside of the room. The vertical frames 23, 34 of this embodiment differ from the vertical frames 23, 34 of the previous embodiment in that the outer periphery of the exterior side view walls 23c, 34c is provided with bent pieces 23e, 34e that bend toward the interior side of the interior side view walls 23b, 34b.
[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 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 an indoor side portion of the main body 112b having a width dimension smaller than the indoor side mounting steel material 111, and an outdoor side portion of the main body 112b having a width dimension larger than the indoor side mounting steel material 111, 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]
