[0013] The exterior cover 112 that constitutes the upright 11 is made of a metal material such as aluminum alloy, and has an exterior appearance wall (cover wall) 112a that covers the exterior connecting parts of the left and right vertical frames 23, 34, and tight materials s112, s112 that abut against the left and right vertical frames 23, 34 are provided on the indoor side of the exterior appearance wall 112a.

[0014] The exterior cover 112 is placed on the exterior side of the mounting steel material 111 and fixed to the mounting steel material 111 with screws b2, b2, and the watertight materials s112, s112 are pressed against the exterior sides of the left and right vertical frames 23, 34 to maintain watertightness on the exterior side of the connecting parts of the vertical frames 23, 34.

[0015] The left and right through anchors 12, 12 are made of a metal material such as steel, are arranged on the left and right sides of the mounting steel material 111, and are fixed to the mounting steel material 111 with screws b3. As shown in FIG. 2, the through anchor 12 of this embodiment has a longitudinal dimension that is shorter than the longitudinal dimension of the mounting steel material 111, enabling it to be connected to the vertical member mounting members (anchors) 5, 5 at the upper and lower positions of the mounting steel material 111 using screws b1, b1.

[0016] The left and right vertical frames 23, 34 are held by the exterior cover 112 on the exterior side, and are attached to the left and right sides of the vertical member 1 by being fixed to the through anchors 12 with screws b4 on the interior side. The vertical frames 23, 34 attached to the left and right sides of the vertical member 1 have an exterior cover 112 arranged on the exterior side of the connecting portion, and an interior member 7 with a fireproof board 71 inside is arranged on the interior side of the connecting portion.

[0017] As described above, the connecting 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.

[0018] (Vertical frame connection using vertical members) The 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, as shown in Figures 4 and 5, and is a long member with a rectangular cross-section and a hollow shape. The manufacturing method of the mounting steel member 111 is not limited.

[0019] As shown in Figures 4 and 5, the outdoor cover 112 that constitutes the upright 11 has an outdoor visible wall 112a, two left and right visible walls 112b, 112b that protrude upward and downward toward the room from the indoor side of the outdoor visible wall 112a, and protrusions 112c, 112c that extend left and right from the outer surfaces of the two left and right visible walls 112b, 112b.

[0020] The outdoor cover 112 has weatherstripping material mounting grooves 112d, 112d provided along the longitudinal direction on the indoor side of the outdoor outdoor visible wall 112a in a portion extending to the left of the left visible wall 112b, and in a portion extending to the right of the right visible wall 112b, and weatherstripping materials s112, s112 are attached to the weatherstripping material mounting grooves 112d, 112d.

[0021] The protrusion 112c of the outdoor cover 112 has a receiving portion 112g at its tip which has an indoor side piece 112e and an outdoor side piece 112f and opens to the left and right, and a guide surface 112h is formed on the inside of the indoor side piece 112e which slopes toward the outside as it enters the inside of the receiving portion 112g.

[0022] The exterior cover 112 is placed on the exterior side of the mounting steel material 111, and with the exterior side of the mounting steel material 111 inserted between the left and right concealed walls 112b, 112b, the left and right side surfaces of the mounting steel material 111 are fixed to the left and right concealed walls 112b, 112b with screws b2.

[0023] The upright 11, formed by fixing an exterior cover 112 to the exterior side of the mounting steel material 111, has as a whole a main body portion 11a, an exterior cover portion 11b having an exterior visible wall 112a located on the exterior side of the main body portion 11a and extending in the left-right direction, and left and right protrusions 112c, 112c located on the sides of the main body portion 11a.

[0024] As shown in Figures 4 and 5, the through anchor 12 is a member with an L-shaped cross section having a projection wall 12a and an attachment portion 12b that continues from the exterior end of the projection wall 12a and bends toward the vertical frame, and is a long member with a length dimension shorter than that of the upright 11. The left and right through anchors 12, 12 have their projection walls 12a, 12a abutted against the indoor sides of the left and right projection walls of the mounting steel material 111 and are fixed in place by screws b3, b3.

[0025] The vertical frames 23, 34 of the left and right sliding windows 2, 3 have concealed walls 23a, 34a, indoor-side concealed walls 23b, 34b extending in the inner and outer periphery directions from the indoor-side ends of the concealed walls 23a, 34a, outdoor-side concealed walls (outdoor-side concealed pieces) 23c, 34c extending in the inner and outer periphery directions from the outdoor-side ends of the concealed walls 23a, 34a, and outer-periphery-side concealed pieces (indoor-side concealed pieces) 23d, 34d extending in the outer periphery direction from the outer periphery side closer to the room of the concealed walls 23a, 34a.

[0026] The vertical frames 23, 34 are arranged on the left and right sides of the upright 11, the tips of the exterior facing walls (exterior facing pieces) 23c, 34c are received in the receiving portions 112g of the exterior cover 112, and the outer peripheral facing pieces (interior facing pieces) 23b, 34b are abutted against the mounting portions 12b of the through anchors 12, 12 from the interior side, and are connected to the vertical member 1 by screws b4, b4 from the interior side.

[0027] The vertical member 1 to which the vertical frames 23, 34 are attached has the exterior side of the exterior facing wall (exterior facing piece) 23c, 34c of the vertical frames 23, 34 abutting or pressed against the exterior piece 112f of the receiving portion 112g of the exterior cover 112, and the tight materials s112, s112 provided on the indoor side of the exterior facing wall (cover wall) 112a is pressed against the exterior side of the exterior facing wall 23c, 34c of the vertical frames 23, 34.

[0028] (Steps for connecting windows using vertical members) An example of the construction procedure for the connection part of the sliding window of the fire prevention equipment of this embodiment will be described with reference to the drawings. Note that the connection procedure for the left and right vertical frames to the vertical member 1 is the same, so in the following explanation, the vertical frame 23 connected to the right side of the vertical member 1 will be used.

[0029] As shown in Figure 6(a), prior to connecting the left and right vertical frames 23, 34 of the vertical member 1, the through anchors 12 are fixed to the left and right sides of the mounting steel material 111 of the upright 11 with screws b3, and the exterior cover 112 is fixed to the outside of the room with screws b2. Then, the vertical frame 23 is positioned on the left and right sides of the vertical member 1, approaching it from the right side and indoor side (arrow x1) so that the outer peripheral end of the outdoor viewing wall (outdoor viewing piece) 23c is inserted into the receiving portion 112g of the outdoor cover 112.

[0030] As the vertical frame 23 is brought closer to the vertical member 1, the outer peripheral end of the outdoor facing wall (outdoor facing piece) 23c of the vertical frame 23 is inserted into the receiving portion 112g of the outdoor cover 112. However, as shown in FIG. 6(b), a guide surface 112h is formed at the entrance of the receiving portion 112g of the outdoor cover 112, so that the outer peripheral end of the outdoor facing wall 23c can be smoothly guided into the receiving portion 112g without letting it slip away.

[0031] With the outer peripheral end of the outdoor facing wall 23c of the vertical frame 23 inserted into the receiving portion 112g of the outdoor cover 112, the vertical frame 23 is brought even closer to the vertical member 1 (arrow x2) so that the outer peripheral facing piece (indoor facing piece) 23d passes through and abuts against the indoor side of the mounting portion 12b of the anchor 12, as shown in Figure 7(a).

[0032] At this time, the outer peripheral end of the outdoor visible wall 23c of the vertical frame 23 approaches the outdoor exterior piece 112f within the receiving portion 112g, but since the weatherstripping material s112 provided on the outdoor cover 112 is positioned inside the room rather than the indoor side of the outdoor exterior piece 112f of the receiving portion 112g, the outdoor visible wall 23c abuts against the weatherstripping materials s112, s112 before abutting against the outdoor exterior piece 112f.

[0033] Thereafter, the outer peripheral end piece 23d of the vertical frame 23 and the mounting portion 12b of the through anchor 12 are fastened together from the inside of the room using the screws b4. The vertical frame 24 is attached by pressing the exterior side of the exterior exterior wall 23c against the exterior piece 112f of the receiving portion 112g as shown in Figure 7 (b) by tightening the outer circumferential piece 23d to the mounting portion 12b of the through anchor 12 with a screw b4.

[0034] The vertical frame 23 attached to the vertical member 1 is restricted from further movement as the exterior side of the exterior visible wall 23c of the vertical frame 23 abuts against the exterior piece 112f of the receiving portion 112g, and the exterior visible wall (outside visible piece) 23c is pressed and welded in an appropriate manner against the watertight material s112 provided on the exterior cover 112, thereby maintaining a watertight condition on the exterior side of the connection between the vertical frames 23, 34. 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.

[0035] (Effect of the fire prevention equipment of the embodiment) As described above, in the connecting equipment of this embodiment, the vertical frames 23, 34 of the left and right windows 2, 3 are connected via steel mounting materials 111 and through anchors 12, 12, so that the left and right windows 2, 3 can be firmly connected. Furthermore, 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 through anchors 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.

[0036] 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 outdoor cover 112, and a receiving portion (protrusion) 112c provided on the outdoor cover 112 abuts against the outdoor exterior walls (outdoor exterior pieces) 23c, 34c of the vertical frames 23, 34. As a result, no gaps are created between the vertical frames 23, 34 and the outdoor cover 112, preventing the intrusion of flames from outside and improving fire resistance.

[0037] The connecting equipment of this embodiment covers the outdoor-side connecting parts of the vertical frames 23, 34 of the left and right windows 2, 3 with an outdoor-side cover 112 equipped with dry watertight material, and by fixing the vertical frames 23, 34 to the uprights 11, the watertight material s112 is pressed against the outdoor-side faces of the vertical frames 23, 34, thereby improving the watertight performance with simple construction.

[0038] The connecting equipment of this embodiment can receive the outdoor facing wall (outdoor facing piece) 23c, 34d of the vertical member 1 using the receiving portion 112g provided on the outdoor cover 112, and then fix the indoor side of the vertical frames 23, 34 with screws, making it easy to position the vertical frames 23, 34 in the projecting direction relative to the vertical member 1, and since the fixing of the vertical frames 23, 34 to the vertical member 1 is completed by the connection on the indoor side, installation is easy.

[0039] The connecting equipment of this embodiment can position the outdoor cover 112 in the forward direction by having the receiving portion 112g provided on the outdoor cover 112 abut against the outdoor side surfaces of the vertical frames 23, 34, and can press the dry watertight material against the vertical frames 23, 34 in an optimal condition, thereby improving fire resistance and watertightness with simple construction.

[0040] The shape and configuration of each member of the connection equipment of the present invention are not limited to the shape and configuration of each member of the connection equipment of the above embodiment. For example, the exterior facing piece of the vertical frame of the present invention may be formed by a facing piece extending from the outer periphery of the concealed wall in the outer periphery direction, similar to the interior facing piece, and the interior facing piece of the vertical frame may be formed by an interior facing wall that continues from the interior end of the concealed wall, similar to the exterior facing piece.

[0041] Furthermore, the shape and configuration of the upright of the present invention are not particularly limited, and the upright may have any shape and configuration as long as it is formed by connecting the mounting steel material and the exterior cover or by forming it as a single piece, so that the upright 11 has a main body portion 11a and an exterior cover portion 11b, and has an exterior visible wall and left and right protrusions located on the interior side of the wall. For example, a protrusion may be provided on the mounting steel material 111 by welding or the like, and the main body portion 11a and the outdoor cover portion 11b of the upright 11 and the protrusion may be formed as a single unit. 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]
