[Modes for carrying out the invention]

[0009] The embodiments of this disclosure will be described below with reference to the drawings. However, this disclosure is not limited in any way to the embodiments described below, and may be implemented with appropriate modifications without departing from the spirit of this disclosure.

[0010] [First Embodiment] As shown in Figure 1, the curtain wall 100 comprises a curtain wall body 120 and a plurality of fasteners 70. Hereafter, as shown in Figure 4, the "front," "back," "left," and "right" directions when viewing the curtain wall body 120 from the front will be simply referred to as "front F," "back B," "left L," and "right R," respectively. Therefore, in the following, the "front-back direction FB" is the thickness direction of the curtain wall body 120, and the "left-right direction LR" is the width direction of the curtain wall body 120.

[0011] The curtain wall body 120 comprises mullions 122 arranged in the left-right direction (LR), transoms 123 arranged in the vertical direction, and multiple panels 125 such as glass panels. Each mullion 122 extends in the vertical direction. Each transom 123 extends in the left-right direction (LR). Each panel 125 is provided in the portion enclosed by two mullions 122 arranged in the left-right direction (LR) and two transoms 123 arranged in the vertical direction.

[0012] Hereinafter, a portion mainly composed of each panel 125 at a predetermined height is referred to as a "wall unit 120u". That is, each wall unit 120u includes one panel 125 and its peripheral portion. The fastener 70 is provided between the wall units 120u arranged in the left - right direction LR.

[0013] The building body 130 includes, for example, a building body main body 135 such as a steel frame, and a building body separate part 132 attached to the building body main body 135.

[0014] As shown in FIG. 4, the mullion 122 protrudes rearward from the rear surface of the curtain wall main body 120. The material of each mullion 122 is aluminum or the like. As shown in FIG. 5, the curtain wall 100 includes a bracket 20 for each fastener 70. Both the bracket 20 and the fastener 70 are made of high - strength aluminum.

[0015] As shown in FIG. 5, the bracket 20 includes a bracket base 22 extending in the vertical direction, and a bracket protrusion 25 protruding rearward B from the upper end of the bracket base 22. The bracket base 22 is fixed to the mullion 122 with bolts 19 or the like. A through - hole 251 extending in the vertical direction is provided in the bracket protrusion 25. A self - weight receiving bolt 28 extending in the vertical direction is passed through the through - hole 251 from above. A nut 281 is screwed onto a portion of the self - weight receiving bolt 28 located below the through - hole 251. The upper surface of the nut 281 abuts against the lower surface of the bracket protrusion 25. The lower end of the self - weight receiving bolt 28 abuts against the upper end of the fastener 70.

[0016] As shown in FIG. 7, the fastener 70 includes a fastener main body 60, a fastener separate part 30, a left - right slide engagement part 40, and a separate body fixing part 50.

[0017] The fastener body 60 comprises a body base 65 and a body riser 62. The body base 65 extends in the left-right direction (LR) and the front-back direction (FB). As shown in Figure 5, the body riser 62 protrudes upward from the front end of the body base 65. As shown in Figure 7, this body riser 62 extends in the left-right direction (LR).

[0018] The separate fastener section 30 comprises a separate horizontal section 35 and a separate vertical section 32. The separate horizontal section 35 extends along the upper surface of the main body base 65 in the left-right direction (LR) and the front-rear direction (FB). As shown in Figure 5, the separate vertical section 32 extends upward from the front end of the separate horizontal section 35 along the rear surface of the main body riser section 62. As shown in Figure 7, this separate vertical section 32 extends in the left-right direction (LR).

[0019] Hereinafter, the sliding of the separate fastener part 30 in the left-right direction (LR) relative to the fastener body 60 will simply be referred to as "left-right sliding." The left-right dimensions (LR) of the separate fastener part 30 are smaller than the left-right dimensions (LR) of the fastener body 60, within the range that allows for left-right sliding.

[0020] The left and right sliding engagement portion 40 shown in Figure 7 is a part that allows the separate fastener portion 30 to be slidably engaged with the fastener body 60 during the construction of the curtain wall 100. The left and right sliding engagement portion 40 includes left and right elongated holes 46 and rails 43.

[0021] As shown in Figure 5, the left and right elongated holes 46 are provided in the middle of the main body rising portion 62 in the vertical direction. These left and right elongated holes 46 penetrate the main body rising portion 62 in the front-rear direction FB. As shown in Figure 7, the left and right elongated holes 46 extend in the left-right direction LR. The separate vertical portion 32 is attached to the bracket 20 by bolts 29 that pass through these left and right elongated holes 46. Specifically, the screw-to-receive member 291 is attached to the inside of the bracket 20 so that it is exposed at the rear B. The separate vertical portion 32 is provided with through holes 321 that penetrate in the front-rear direction FB. The through holes 321 communicate with the left and right elongated holes 46. The bolts 29 are passed through these through holes 321 and the left and right elongated holes 46. The front end of the bolt 29 is screwed into the screw-to-receive member 291, thereby attaching the separate vertical portion 32 to the bracket 20.

[0022] The rail 43 shown in Figure 7 is provided at the upper end of the main body riser portion 62. Specifically, as shown in Figure 5, the upper end of the main body riser portion 62 is provided with an upper end projection 63 that protrudes to the rear B. This upper end projection 63 extends in the left-right direction LR. The rail 43 is provided on the lower surface of this upper end projection 63. The rail 43 is in the shape of a grooved wall that is recessed upwards. As shown in Figure 7, the rail 43 extends in the left-right direction LR along the upper end projection 63.

[0023] As shown in Figure 5, the upper end of the separate vertical portion 32 is positioned inside the rail 43. This causes the separate fastener portion 30 to be sandwiched between the rail 43 and the main body base 65. As a result, the separate fastener portion 30 engages with the fastener body 60 shown in Figure 7 in a way that allows it to slide left and right.

[0024] The separate fixing part 50 shown in Figure 7 prevents it from sliding left or right. In this embodiment, the separate fixing part 50 is one or more screws or bolts. Specifically, as shown in Figure 5, the separate horizontal part 35 is provided with a through hole 351 that penetrates in the vertical direction. The main body base 65 is provided with an engagement hole 651 that communicates with the through hole 351. The separate fixing part 50, which is a screw or bolt, is fixed to the main body base 65 by engaging with the engagement hole 651 after passing through the through hole 351. As a result, the separate fastener part 30 is fixed to the fastener body 60 shown in Figure 7 in a way that prevents it from sliding left or right.

[0025] As shown in Figure 5, the lower end of the self-weight support bolt 28 abuts against the portion located on the back side of the rail 43 on the upper surface of the main body rising portion 62.

[0026] As shown in Figure 7, the curtain wall 100 further includes a front-to-back sliding engagement portion 80 and a main body fixing portion 90. Hereinafter, the sliding of the fastener body 60 in the front-to-back direction FB relative to the building structure 130 will simply be referred to as "front-to-back sliding".

[0027] The front-to-rear sliding engagement portion 80 is a part that allows the fastener body 60 to slide back and forth against the building structure 130 during the construction of the curtain wall 100. Specifically, in this embodiment, the front-to-rear sliding engagement portion 80 includes two front-to-rear elongated holes 82 provided in the main body base portion 65, and a total of two bolts 85, one for each of the front-to-rear elongated holes 82.

[0028] Two front and rear elongated holes 82 are provided at the rear of the main body base 65, spaced apart in the left-right direction (LR). Each front and rear elongated hole 82 extends in the front-rear direction (FB). As shown in Figure 5, each front and rear elongated hole 82 penetrates the main body base 65 in the vertical direction. Through holes 1321 are provided in the frame 130, communicating with the front and rear elongated holes 82. Each bolt 85 is passed through the through holes 1321 and the front and rear elongated holes 82 from below. A nut 851 is screwed onto the top of the bolt 85. In this way, the fastener body 60 engages with the frame 130 shown in Figure 7, allowing it to slide back and forth within the range of the front and rear elongated holes 82.

[0029] The main body fixing portion 90 shown in Figure 6 prevents it from sliding back and forth. Specifically, in this embodiment, the main body fixing portion 90 includes a plurality of upper surface grooves 98 and a total of two engaging members 94, one for each of the front and rear elongated holes 82. The plurality of upper surface grooves 98 are provided on the upper surface of the main body base portion 65. Each upper surface groove 98 extends in the left-right direction LR. As shown in Figure 5, the plurality of upper surface grooves 98 are arranged side by side in the front-rear direction FB. Each upper surface groove 98 is recessed downwards.

[0030] As shown in Figure 5, each engaging member 94 is provided with a through hole 941 through which a bolt 85 passes. Each engaging member 94 is interposed between a nut 851 and an upper groove 98. Thus, each engaging member 94 is attached to the building structure 130 by a bolt 85 while positioned on the upper groove 98. An underside groove 95 is provided on the underside of the engaging member 94.

[0031] When the bolt 85 shown in Figure 5 is loosely tightened, forward and backward sliding is permitted by the forward and backward sliding engagement portion 80. On the other hand, when the bolt 85 is tightly tightened, the lower groove 95 engages with the portion between the upper grooves 98 on the upper surface of the fastener body 60, making forward and backward sliding impossible.

[0032] The configuration and effects of this embodiment are summarized below.

[0033] The left-right sliding engagement portion 40 shown in Figure 7 engages the separate fastener portion 30 with the fastener body 60 so that it can slide left and right. The separate fixing portion 50 prevents this left-right sliding. Therefore, when constructing the curtain wall 100, the left-right sliding engagement portion 40 can be used to slide the separate fastener portion 30 with respect to the fastener body 60 in the left-right direction (LR). Thus, the position of the separate fastener portion 30 can be adjusted in the left-right direction (LR). In this state, the left-right sliding can be prevented by installing the separate fixing portion 50. Therefore, the curtain wall body 120 can be fixed to the building structure 130 at the desired left-right position by means other than welding. This improves work efficiency and avoids welding problems.

[0034] The procedure described herein constitutes the implementation of a curtain wall construction method. Specifically, this curtain wall construction method includes the steps of performing left-right sliding using the left-right sliding engagement portion 40, and then disabling left-right sliding by installing the separate fixing portion 50. The left-right sliding step described here may be performed, for example, when the separate fastener portion 30 is attached to at least the curtain wall body 120 and the fastener body 60 is attached to the building structure 130, or when only one of these is performed.

[0035] The left and right sliding engagement portion 40 shown in Figure 7 engages the separate fastener portion 30 with the rear surface of the main body rising portion 62 so as to be slidable from side to side. The main body rising portion 62 is provided with left and right elongated holes 46. The separate fastener portion 30 supports the curtain wall body 120 via bolts 29 that pass through the left and right elongated holes 46. Thus, the configuration in which the separate fastener portion 30 is positioned behind the main body rising portion 62 B, as in this embodiment, can be easily realized.

[0036] As shown in Figure 7, the left-right sliding engagement portion 40 includes a rail 43 that extends in the left-right direction LR at the rear of the main body rising portion 62. The upper end of the separate vertical portion 32 engages with the rail 43 so as to be slidable from left to right. Thus, in the embodiment where the separate fastener portion 30 is located at the rear B of the main body rising portion 62, the left-right sliding engagement portion 40 can be realized simply.

[0037] As shown in Figure 7, the separate fixing part 50 is a screw or bolt that fixes the separate horizontal part 35 to the main body base 65. Therefore, the separate fixing part 50 can be implemented simply.

[0038] As shown in Figure 5, the lower end of the self-weight support bolt 28 abuts against the portion located on the back side of the rail 43 at the upper end of the main body rising portion 62. Therefore, the portion of the fastener 70 that abuts against the lower end of the self-weight support bolt 28 can be secured by utilizing the structure for left and right sliding.

[0039] The front-to-back sliding engagement portion 80 shown in Figure 6 engages the fastener body 60 with the building structure 130 so that it can slide back and forth. The body fixing portion 90 prevents this front-to-back sliding. Therefore, when constructing the curtain wall 100, the front-to-back sliding engagement portion 80 can be used to slide the fastener body 60 in the front-to-back direction FB relative to the building structure 130. As a result, the position of the fastener 70 can be adjusted in the front-to-back direction FB. In this state, by installing the body fixing portion 90, the front-to-back sliding can be prevented. Therefore, the curtain wall body 120 can be fixed to the building structure 130 at the desired front-to-back position by means other than welding.

[0040] The procedure described herein constitutes the implementation of a curtain wall construction method. Specifically, the construction method for the curtain wall 100 includes the steps of performing a forward and backward sliding action using the forward and backward sliding engagement portion 80, and then disabling the forward and backward sliding action by installing the main body fixing portion 90. The forward and backward sliding action described herein may be performed, for example, with the fastener separate portion 30 attached to the curtain wall body 120, or before it is attached.

[0041] As shown in Figure 6, the front and rear sliding engagement portion 80 includes front and rear elongated holes 82 provided in the fastener body 60 and a bolt 85 that engages with the frame 130 after passing through the front and rear elongated holes 82. Thus, the front and rear sliding engagement portion 80 can be realized simply.

[0042] As shown in Figure 6, the main body fixing portion 90 includes a plurality of upper grooves 98 and an engaging member 94. The plurality of upper grooves 98 are arranged in the front-to-back direction FB on the upper surface of the fastener body 60. Each upper groove 98 extends in the left-to-right direction LR. As shown in Figure 5, the engaging member 94 is attached to the frame 130 with the engaging member 94 positioned on the upper grooves 98. The lower surface of the engaging member 94 is provided with a lower groove 95 that engages with the space between the upper grooves 98 on the upper surface of the fastener body 60. Thus, the main body fixing portion 90 can be realized simply.

[0043] [Second Embodiment] Next, a second embodiment will be described with reference to Figures 8 and 9. This embodiment will be described based on the first embodiment, focusing on the differences, and explanations of points that are the same as or similar to the first embodiment will be omitted as appropriate.

[0044] As shown in Figure 9, the bracket 20 extends in the left-right direction (LR). The bracket 20 has two vertically elongated holes 222 spaced apart in the left-right direction (LR). As shown in Figure 8, each vertically elongated hole 222 extends in the vertical direction.

[0045] As shown in Figure 8, the separate fastener portion 30 is located in front F of the main body rise portion 62. As shown in Figure 9, the separate fastener portion 30 extends in the left-right direction LR. The separate fastener portion 30 has two through holes 302 spaced apart in the left-right direction LR. Each through hole 302 penetrates the separate fastener portion 30 in the front-rear direction FB. Each through hole 302 communicates with the upper and lower elongated holes 222. A bolt 29 is passed through these through holes 302 and the upper and lower elongated holes 222. The separate fastener portion 30 is attached to the bracket 20 by screwing a nut 292 onto the tip of the bolt 29.

[0046] The left-right sliding engagement portion 40 shown in Figure 9 engages the fastener separate portion 30 with the front surface of the main body rising portion 62 so that it can slide left and right. The left-right sliding engagement portion 40 comprises an upper rail 43u and a lower rail 43d, as shown in Figure 8. Specifically, an upper projection 63u protruding forward F is provided at the upper end of the main body rising portion 62. A lower projection 63d protruding forward F is provided at the lower end of the main body rising portion 62. These upper projection 63u and lower projection 63d each extend in the left-right direction LR. An upper rail 43u is provided on the lower surface of the upper projection 63u. A lower rail 43d is provided on the upper surface of the lower projection 63d. The upper rail 43u has a grooved wall surface that is recessed upward. The lower rail 43d has a grooved wall surface that is recessed downward. The upper rail 43u extends in the left-right direction (LR) along the upper projection 63u. The lower rail 43d extends in the left-right direction (LR) along the lower projection 63d.

[0047] As shown in Figure 8, the upper end of the separate fastener portion 30 is positioned inside the upper rail 43u. The lower end of the separate fastener portion 30 is positioned inside the lower rail 43d. As a result, the separate fastener portion 30 engages with the fastener body 60 in a way that allows it to slide left and right.

[0048] As shown in Figure 9, the separate fixing part 50 is one or more screws or bolts. The separate fixing part 50 fixes the upper end of the fastener separate part 30 to the upper end of the main body rising part 62 in a way that prevents it from sliding left or right.

[0049] As shown in Figure 8, the lower end of the self-weight support bolt 28 abuts against the portion located on the back side of the upper rail 43u on the upper surface of the main body rising portion 62.

[0050] The configuration and effects of this embodiment are summarized below.

[0051] The left and right sliding engagement portion 40 shown in Figure 9 engages the separate fastener portion 30 with the front surface of the main body rising portion 62 in a way that allows it to slide left and right. As a result, the configuration in which the separate fastener portion 30 is positioned in front of the main body rising portion 62, as in this embodiment, can be easily realized.

[0052] As shown in Figure 8, the left-right sliding engagement portion 40 includes an upper rail 43u provided at the front of the upper end of the main body rise portion 62 and a lower rail 43d provided below it. The upper end of the separate fastener portion 30 engages with the upper rail 43u so as to be slidable left and right. The lower end of the separate fastener portion 30 engages with the lower rail 43d so as to be slidable left and right. Thus, in the embodiment where the separate fastener portion 30 is positioned in front of the main body rise portion 62, the left-right sliding engagement portion 40 can be simply realized.

[0053] As shown in Figure 9, the separate fixing part 50 is a screw or bolt that fixes the separate fastener part 30 to the main body riser part 62. Therefore, the separate fixing part 50 can be implemented simply.

[0054] As shown in Figure 8, the lower end of the self-weight support bolt 28 abuts against the portion located on the back side of the upper rail 43u at the upper end of the main body rising portion 62. Therefore, the portion of the fastener 70 that abuts against the lower end of the self-weight support bolt 28 can be secured by utilizing the structure for left and right sliding.

[0055] [Third Embodiment] Next, a third embodiment will be described with reference to Figures 10 and 12. This embodiment will also be described based on the first embodiment, focusing on the differences, and explanations of points that are the same as or similar to the first embodiment will be omitted as appropriate.

[0056] As shown in Figure 10, the fastener body 60 consists only of the body base 65 as in the first embodiment, and does not have the body riser portion 62 as in the first embodiment. Therefore, the body riser portion 62 as in the first embodiment is not interposed between the bracket base 22 and the separate vertical portion 32.

[0057] The left-right sliding engagement portion 40 shown in Figure 12 engages the separate fastener portion 30 with the upper surface of the front end of the fastener body 60 so that it can slide left and right. The left-right sliding engagement portion 40 includes a front rail 43f and a rear rail 43b. Specifically, as shown in Figure 10, a front projection 63f is provided on the front end of the upper surface of the fastener body 60, projecting upward. A rear projection 63b is provided on the upper surface of the fastener body 60 at a point B behind the front projection 63f, projecting upward. As shown in Figure 12, these front projection 63f and rear projection 63b each extend in the left-right direction LR. As shown in Figure 10, the front rail 43f is provided on the rear surface of the front projection 63f. The rear rail 43b is provided on the front surface of the rear projection 63b. The front rail 43f is a grooved wall surface that is recessed toward the front F. The rear rail 43b is a grooved wall that is recessed towards the rear B. As shown in Figure 12, the front rail 43f extends in the left-right direction L and R along the front projection 63f. The rear rail 43b extends in the left-right direction L and R along the rear projection 63b.

[0058] As shown in Figure 10, the front end of the separate horizontal section 35 is positioned inside the front rail 43f. The rear end of the separate horizontal section 35 is positioned inside the rear rail 43b. As a result, the separate fastener section 30 engages with the fastener body 60 shown in Figure 12 in a way that allows it to slide left and right.

[0059] As shown in Figure 12, the separate fixing part 50 is one or more screws or bolts. The separate fixing part 50 fixes, for example, the separate horizontal part 35 to the upper surface of the front end of the fastener body 60 so that it cannot slide from side to side.

[0060] As shown in Figure 10, the lower end of the self-weight support bolt 28 abuts against the upper surface of the separate vertical section 32.

[0061] The configuration and effects of this embodiment are summarized below.

[0062] The left and right sliding engagement portion 40 shown in Figure 12 engages the separate fastener portion 30 with the upper surface of the front end of the fastener body 60, enabling it to slide left and right. As a result, the configuration in which the separate fastener portion 30 is positioned on the front end of the fastener body 60, as in this embodiment, can be easily realized.

[0063] As shown in Figure 10, the left-right sliding engagement portion 40 includes a front rail 43f provided on the upper part of the front end of the fastener body 60 and a rear rail 43b provided therebelow B. The front end of the separate horizontal portion 35 engages with the front rail 43f in a left-right slidable manner. The rear end of the separate horizontal portion 35 engages with the rear rail 43b in a left-right slidable manner. Thus, in the embodiment where the separate fastener portion 30 is placed on top of the front end of the fastener body 60, as in this embodiment, the left-right sliding engagement portion 40 can be simply realized.

[0064] As shown in Figure 12, the separate fixing part 50 is a screw or bolt that fixes the separate horizontal part 35 to the fastener body 60. Therefore, the separate fixing part 50 can be implemented simply.

[0065] As shown in Figure 10, the lower end of the self-weight support bolt 28 abuts against the upper end of the separate vertical part 32. Therefore, the portion of the fastener 70 that abuts against the lower end of the self-weight support bolt 28 can be secured using the separate vertical part 32.

[0066] [Other embodiments] The above embodiments can be implemented with modifications, for example, as follows.

[0067] The separate fixing part 50 shown in Figures 5 and 9 may be changed from a screw or bolt to an adhesive that bonds and fixes the separate fastener part 30 to the fastener body 60. The main body fixing part 90 may also be changed to an adhesive that bonds and fixes the fastener body 60 to the frame 130.
