Description

[Technical Field]

[0001] The present invention relates to a channel fixing fixture and a channel fixing method for fixing the end of a channel extending between a pair of furring strips to the furring strips. [Background technology]

[0002] Warehouses, factories, and other buildings often use steel-frame construction, in which exterior wall materials are supported by multiple studs and multiple furring strips that span between the studs and are fixed at their ends to the studs. In these buildings, no interior wall materials are used, so the studs and furring strips are exposed. Therefore, when installing equipment such as wiring boxes, wiring panels, fire alarms, and electrical conduits inside the walls, channels to support the equipment are installed between the furring strips.

[0003] The so-called C-channel, which allows for easy attachment and detachment of equipment, is often used as a channel, and in order to secure the channel to an object, a metal fitting is known in which one end of the L-shaped bent piece is secured to the channel and the other end is secured to the surface of the object, such as a furring strip, against which the end of the channel abuts (for example, Patent Document 1). [Prior art documents] [Patent documents]

[Effects of the Invention]

[0019] According to the inventions described in claims 1 and 12, the steel fixing portion that fixes the channel is configured to have a rail portion that extends in the depth direction of the furring strip. Therefore, by fixing the channel at any position on the rail portion, it is possible to install the channel at any position in the depth direction of the furring strip, and ultimately it is possible to provide a channel fixing fitting that is highly versatile.

[0020] According to the invention described in claim 2, the channel can be fixed simply by inserting the end of the channel between a pair of side panels which are rail portions, sliding it to the desired position, and inserting and tightening screws into the holes provided in the pair of side panels, thereby making it possible to easily adjust the depth-wise position of the furring strip.

[0024] According to the invention described in claim 6, since there is only one side panel which is the rail portion, processing is easy, and the channel can be fixed by simply sliding it to any position along the side panel and inserting and tightening a square U-bolt into the hole provided in the side panel, making it possible to easily adjust the position of the furring strip in the depth direction.

[0025] According to the invention described in claim 7, the rail portion is a rail channel material that extends in the depth direction of the furring strip, and the fixing member for attaching the channel to the rail channel material is slidably attached to the rail channel material. Therefore, unlike when the channel is attached with a screw or bolt, the attachment position of the channel is not limited to the position or size of the hole for inserting the screw or bolt, and the depth direction position of the furring strip can be adjusted more accurately and easily.

[0026] According to the invention described in claim 8, the channel fixing portion provided on the fixing member comprises a channel insertion portion that is inserted into the channel and a screw hole provided in the channel insertion portion, and the channel insertion portion is screwed into the channel insertion portion and pressed against the lip portion of the channel to fix it, which makes it easy to work with and allows the channel fixing bracket to be easily attached to the channel.

[0027] According to the invention described in claim 9, the channel fixing portion provided on the fixing member comprises a channel abutment portion that abuts against the front portion where the opening of the channel is provided, and a pressure plate that is housed within the channel, and the lip portion of the channel is clamped and fixed between the pressure plate and the channel abutment portion, so that load is applied only to the lip portion, suppressing load on other parts of the channel and making it possible to prevent deformation of the channel, etc.

[0031] The present invention will be described below based on the illustrated embodiments.

[0032] (Embodiment 1) Fig. 1 is a first perspective view (A) and a side view (B) showing a channel fixing bracket 1 according to this embodiment, and Fig. 2 is a perspective view showing a state in which a channel C is fixed between a pair of furring strips F1 and F2 by the channel fixing bracket 1. This channel fixing bracket 1 is a bracket for fixing and supporting a channel C, which is used to support various devices, electrical conduits, etc., between a pair of furring strips F1 and F2.

[0033] Here, a pair of furring strips F1, F2 are architectural steel members that are inserted between multiple partition walls (not shown) and fixed at their ends to the partition walls, supporting the exterior wall material E (shown by hatching in Figure 2) together with the partition walls, and are used in steel-frame buildings. The furring strips F1, F2 are horizontal furring strips that are arranged in a roughly horizontal direction and have a roughly U-shaped cross section, consisting of a channel with lips that face each other from both edges.

[0034] The channel C is a long body with a generally U-shaped cross section and opposing lip portions C1 formed at both edges. That is, side portions C3 extend generally perpendicularly from both edges of the band-shaped back portion C2. Furthermore, opposing short-side lip portions C1 extend from the edges of the opposite side of the back portion C2 of each side portion C3, generally parallel to the back portion C2 or folded inward, to form the opposing short-side lip portions C1. In this embodiment, the channel C is positioned so that its opening, i.e., the opening side with the lip portions C1, faces the front. The channel C is fixed at any position between the front and back of the furring strips F1 and F2, i.e., at any position in the depth direction perpendicular to the longitudinal direction of the furring strips F1 and F2.

[0035] Below, we will explain the lower channel fixing bracket 1 that fixes the channel C to the lower furring strip F1. Note that the upper channel fixing bracket 1 that fixes the channel C to the upper furring strip F2 is the same one used upside down, so a detailed explanation will be omitted.

[0036] The channel fixing bracket 1 comprises a furring strip fixing portion 2, a steel fixing portion 3 consisting of a rail portion 31 and a fixing member 32, a connecting portion 4, and a screw 5. The furring strip fixing portion 2 is formed by bending a substantially rectangular metal plate in the length direction, and the pair of left and right side panels 311 that make up the rail portion 31 are formed by bending the plate at two points in the width direction, with connecting portions 4 provided at the portions that connect the furring strip fixing portion 2 and the pair of side panels 311. The thickness and width of the plates that make up the furring strip fixing portion 2, the pair of side panels 311, and the connecting portion 4 are set so as to obtain the strength necessary to fix and support a channel C that supports various devices such as wiring boxes.

[0037] The furring strip fixing part 2 is arranged to hang down in a substantially vertical direction from one end of the connecting part 4 and abuts against the front surface F11 of the furring strip F1. Two screw insertion holes 21 are provided at the left and right ends of the furring strip fixing part 2. The number of screw insertion holes 21 is not limited to two, and may be one located approximately in the center of the furring strip fixing part 2, or three or more.

[0038] As shown in Figure 1, the pair of side panels 311 are provided to rise substantially vertically from both sides of the connecting portion 4, and when the fitting 1 is attached to the furring strip F1, they extend in the depth direction of the furring strip F1. Such a pair of side panels 311 are formed by bending both sides of a plate-like body so that they rise. Here, the plate-like body refers to the plate material that is used to form the pair of side panels 311 and the connecting portion 4. The distance between one side panel 311 and the other side panel 311 is formed slightly larger than the width dimension of the channel C, and when the channel fixing fitting 1 is attached to the channel C, the end of the channel C is inserted between the pair of side panels 311.

[0039] Three elongated holes 3111 are formed at any position in the longitudinal direction of the pair of side panels 311 (the direction that corresponds to the depth direction of the furring strip F1 when the fitting 1 is attached to the furring strip F1), and when attaching the channel fixing fitting 1 to the channel C, it is fixed by inserting a screw 321, which is the fixing member 32, into one of the holes 3111 and tightening it. For example, a drill screw is used as the screw 321.

[0040] The pair of side panels 311 have holes 3111 formed in the longitudinal direction, into which the screws 321 are inserted, making it easy to adjust the position of the furring strip F1 in the depth direction. The shape of the holes 3111 is not limited to an elongated hole, and may be, for example, a horizontally elongated oval. The number of holes 3111 is also not limited to three, and may be less than three or four or more depending on the length of the side panels 311 and the size of the holes 3111.

[0041] The connecting part 4 is connected to the lower ends of the pair of side panels 311 and the upper ends of the furring strip fixing parts 2, and is provided so as to extend substantially horizontally. The length of the connecting part 4 in the depth direction of the furring strip F1 is set to be equal to or greater than the length of the length of the side panels 311 in the longitudinal direction, and equal to or less than the depth length of the furring strip F1.

[0042] Next, the fixing of the channel C by the channel fixing metal fitting 1 will be described with reference to FIG.

[0043] First, the end of the channel C is inserted between the pair of side plates 311 so that the lip portion C1 of the channel C faces the furring strip fixing portion 2 side (front side) of the channel fixing bracket 1, and slid to any position, and screws 321 are inserted into holes 3111 provided in the pair of side plates 311 to fix the channel C to the channel fixing bracket 1. Furthermore, although not described in detail, the upper end of the channel C is fixed to the channel fixing bracket 1 in a similar manner.

[0044] Next, the channel C, with channel fixing brackets 1 attached to both ends, is inserted between a pair of furring strips F1 and F2, and the furring strip fixing parts 2 are abutted against the front faces F11 and F21 of the furring strips F1 and F2. Then, screws 5 are inserted into the screw insertion holes 21 of the furring strip fixing parts 2 and screwed into the furring strips F1 and F2. For example, drill screws are used as the screws 5. In this way, the channel C can be installed at any position in the depth direction of the furring strips F1 and F2. Note that the channel C may be fixed to the channel fixing brackets 1 after the channel fixing brackets 1 are fixed to the furring strips.

[0045] (Variation 1-1) 3(A) to 3(D) are perspective views showing a modified example 1-1 of the channel fixing metal fitting 1 according to the first embodiment.

[0046] In the channel fixture 1 of embodiment 1 described above, the pair of side plates 311 were formed by bending both sides of a plate-like body, but in this modified example, they are formed by cutting and raising the inside of the plate-like body. The distance between one side plate 311 and the other side plate 311 is made slightly larger than the width dimension of the channel C, just like the channel fixture 1 shown in Figure 1, and when attaching the channel fixture 1 to the channel C, the end of the channel C is inserted between the pair of side plates 311.

[0047] In the channel fixing bracket 1 of Modification 1-1, the connecting portion 4 extends outside the pair of side plates 311, so the channel C can be stably fixed by the channel fixing bracket 1. Furthermore, the channel fixing bracket 1 of Modification 1-1 can be formed so that the installation positions of the pair of side plates 311 can be adjusted in the width and length directions of the connecting portion 4. Specifically, as shown in FIG. 3(A), the pair of side plates 311 can be formed across the entire length of the connecting portion 4, as shown in FIG. 3(B), the pair of side plates 311 can be formed with a space on the front side of the connecting portion 4 in the length direction, as shown in FIG. 3(C), the pair of side plates 311 can be formed with a space on the rear side of the connecting portion 4 in the length direction, as shown in FIG. 3(D), or the pair of side plates 311 can be formed with a space on both the front and rear sides of the connecting portion 4 in the length direction.

[0048] The fixing of the channel C by the channel fixing bracket 1 of Modification 1-1 and the attachment of the channel C to the furring strips F1 and F2 are the same as those of the channel fixing bracket 1 of the first embodiment described above, and therefore will not be described here.

[0049] (Variation 1-2) FIG. 4 is a perspective view showing a modified example 1-2 of the channel fixing metal fitting 1 according to the first embodiment.

[0050] The channel fixing bracket 1 of Modification 1-2 is a split type channel fixing bracket 1 formed by splitting the channel fixing bracket 1 of the above-mentioned first embodiment (see FIG. 1), in which a pair of side panels 311 are formed by bending both sides of a plate-like body, for example, by cutting it at approximately the center in the width direction of the connecting part 4. This type of channel fixing bracket 1 comprises a first fitting 1a comprising a furring strip fixing part 2a, one side panel 311a, and a screw 321a, and a second fitting 1b comprising a furring strip fixing part 2b, the other side panel 311b, and a screw 321b.

[0051] The channel fixing bracket 1 of variant 1-2 can be adapted to channels C of various sizes (widths) because the distance between one side panel 311a and the other side panel 311b (i.e., the distance between the first bracket 1a and the second bracket 1b) can be adjusted as desired.

[0052] Next, the fixing of the channel C by the channel fixing metal fitting 1 of the modified example 1-2 will be described.

[0053] First, one end of the channel C is slid to a desired position on the side panel 311a of the first bracket 1a, and a screw 321a is inserted into a hole 3111a in one of the side panels 311a to secure the channel C to the first bracket 1a. Next, the other end of the channel C is slid along the side panel 311b of the second bracket 1b, and a screw 321b is inserted into a hole 3111b in the side panel 311b at a position where the furring strip fixing portion 2a of the first bracket 1a and the furring strip fixing portion 2b of the second bracket 1b are flush with each other, thereby securing the channel C to the second bracket 1b. The process of attaching the channel C fixed to the channel fixing bracket 1 in this way to the furring strips F1 and F2 is omitted because it is the same as the channel fixing bracket 1 in the first embodiment described above.

[0054] As explained above, according to the channel fixing bracket 1 of this embodiment, the steel fixing portion 3 that fixes the channel C is configured to have a pair of side panels 311 as rail portions 31 extended in the depth direction of the furring strips F1 and F2.Therefore, by fixing the channel C at any position on the pair of side panels 311, it is possible to install the channel C at any position in the depth direction of the furring strips F1 and F2, and ultimately it is possible to provide a channel fixing bracket 1 that is highly versatile.

[0055] Furthermore, according to the channel fixing bracket 1 of this embodiment, the end of the channel C can be inserted between a pair of side panels 311, which are the rail portion 31, and slid to any position, and the channel C can be fixed simply by inserting and tightening screws 321 into the holes 3111 provided in the pair of side panels 311, making it possible to easily adjust the depthwise position of the furring strips F1 and F2.

[0056] Furthermore, with the channel fixture 1 according to this embodiment, the pair of side plates 311 that make up the rail portion 31 can be formed by bending both side pieces of a plate-like body, making processing easy.

[0057] Furthermore, according to the channel fixing bracket 1 relating to a modified example of this embodiment, the pair of side panels 311 that make up the rail portion 31 can be formed by cutting and raising the inside of a plate-shaped body, which makes processing easier and makes it possible to adjust the installation positions of the pair of side panels 311 in the width and length directions of the connecting portion 4.

[0058] Furthermore, according to another modified example of the channel fixing bracket 1 of this embodiment, the channel fixing bracket 1 is divided into two parts, the first bracket 1a and the second bracket 1b, and therefore can be used for channels C of various sizes (widths).

[0059] (Embodiment 2) A channel fixing bracket 1A according to this embodiment differs from embodiment 1 in that only one side panel 311 is provided as the rail portion 31, and in that a square U-bolt is used as the fixing member 32A. As the other components are the same as those of the channel fixing bracket 1 according to embodiment 1, detailed explanation of each component will be omitted.

[0060] 5A is a perspective view of a channel fixing metal fitting 1A according to a second embodiment of the present invention, and FIG. 5B is a perspective view showing the channel fixing metal fitting 1A according to the second embodiment attached to a channel C.

[0061] As shown in Figure 5 (A), the channel fixing bracket 1A of this embodiment comprises a furring strip fixing portion 2, a side panel 311 which is a rail portion 31, a square U-shaped bolt 322 and a nut which are fixing members 32A, a connecting portion 4, and a screw 5.

[0062] The side panel 311 is provided on only one widthwise side of the connecting part 4, rising approximately vertically from the connecting part 4, and extends in the depth direction of the furring strip F1 when the fitting 1A is attached to the furring strip F1. Because only one side panel 311 is required, the channel fixing fitting 1A according to this embodiment is easier to process.

[0063] The side panel 311 may be formed by bending one side edge of a plate-like body so that it stands up, as shown in Fig. 5(A), or may be formed by cutting and raising the inside of a plate-like body (not shown). In the latter case, it becomes possible to adjust the installation position of the side panel 311 in the width direction and length direction of the connecting part 4. Note that the plate-like body here refers to the plate material that is the material for the side panel 311 and the connecting part 4.

[0064] Next, the fixing of the channel C by the channel fixing metal fitting 1A will be described with reference to FIG. 5(B).

[0065] First, one end of the channel C is slid to any position on the side panel 311 so that the lip portion C1 of the channel C faces the furring strip fixing portion 2 side (front side) of the channel fixing bracket 1A, and square U-bolt 322 is inserted into hole 3111 provided in the side panel 311 while straddling the channel C, and then tightened with a nut to fix the channel C to the channel fixing bracket 1A. The process of attaching the channel C fixed to the channel fixing bracket 1A in this way to the furring strips F1, F2 is omitted because it is the same as the channel fixing bracket 1 in the first embodiment described above.

[0066] As explained above, according to the channel fixing bracket 1A of this embodiment, like the channel fixing bracket 1 of embodiment 1, it is possible to install the channel C at any position in the depth direction of the furring strips F1 and F2, which in turn has the effect of making it possible to provide a channel fixing bracket 1A that is highly versatile.In addition, since there is only one side panel 311 which is the rail portion 31, processing is easy, and the channel C can be fixed by simply sliding it to any position along the side panel 311 and inserting and tightening the square U-bolt 322 into the hole 3111 provided in the side panel, thereby making it possible to easily adjust the position of the furring strips F1 and F2 in the depth direction.

[0067] (Embodiment 3) A channel fixing bracket 1B according to this embodiment differs from embodiment 1 in that a rail channel material 312 is used as the rail portion 31, and that a channel fixing portion 323 and a rail fixing portion 324 are used as the fixing member 32B. As the other components are the same as those of the channel fixing bracket 1 according to embodiment 1, detailed explanation of each component will be omitted.

[0068] Figure 6 is an oblique view (A) of a channel fixing bracket 1B relating to an embodiment of the present invention, and an oblique view (B) showing the state in which a channel C is fixed to a lower furring strip F1 using a channel fixing bracket 1B relating to embodiment 3.

[0069] The channel fixing bracket 1B according to this embodiment comprises a furring strip fixing portion 2, a rail channel material 312 which is a rail portion 31, a channel fixing portion 323 and a rail fixing portion 324 which are fixing members 32B, and a screw 5.

[0070] The rail channel 312 is a long body with a generally U-shaped cross section, with opposing lip portions 312a formed at both end edges. That is, side portions 312c extend generally perpendicularly from both edge portions of a strip-shaped back portion 312b, and opposing short-side lip portions 312a extend from the edge of each side portion 312c opposite the back portion 312b, generally parallel to the back portion 312b or folded inward, to the back portion 312b. The back portion 312b of the rail channel 312 serves as the connecting portion 4 in the channel fixing fittings 1 and 1A according to the first and second embodiments.

[0071] The fixing member 32B is formed into a substantially L-shape by bending a substantially rectangular metal plate material at one location in the length direction. The fixing member 32B includes a channel fixing portion 323 provided at one end and a rail fixing portion 324 provided at the other end. The channel fixing portion 323 serves to fix the end of the channel C, and the rail fixing portion 324 serves to fix the channel C at any position on the rail channel member 312. If the lip portions of the rail channel member 312 and the channel C have the same structure, the channel fixing portion 323 and the rail fixing portion 324 of the fixing member 32B can be interchanged. In this case, both the fixing surface 3231 and the fixing surface 3241 are provided with a notch through which the lip portion 312a can pass. Furthermore, it is preferable to use the same screws 6 and 7, which will be described later.

[0072] 6(A), the channel fixing portion 323 includes a channel insertion portion 323a and a screw hole 323b provided in the channel insertion portion 323a. The channel insertion portion 323a includes a fixing surface 3231 and a pair of abutment portions 3232 bent upward from both sides of the fixing surface 3231 so as to be perpendicular to the fixing surface 3231. When a screw 6 is threaded into the screw hole 323b provided in the fixing surface 3231 of the channel insertion portion 323a and the tip of the screw 6 is pressed against the inner wall surface of the back surface C2 of the end of the channel C, the pair of abutment portions 3232 of the channel insertion portion 323a are pressed against the lip portion C1 of the channel C, and the fixing member 32B (channel fixing portion 323) is fixed to the end of the channel C. For example, a set screw is used as the screw 6.

[0073] 6(A), the rail fixing portion 324 includes a rail insertion portion 324a and a screw hole 324b provided in the rail insertion portion 324a. The rail insertion portion 324a includes a fixing surface 3241 and a pair of abutment portions 3242 bent upward from both sides of the fixing surface 3241 so as to be perpendicular to the fixing surface 3241. Then, screws 7 are threaded into the screw holes 324b provided in the fixing surface 3241 of the rail insertion portion 324a, and the rail insertion portion 324a is inserted into the rail channel member 312 and slid. At an arbitrary position, the tip of the screw 7 is pressed against the inner wall surface of the back surface portion 312b of the rail channel member 312, whereby the pair of abutment portions 3242 of the rail insertion portion 324a are pressed against the lip portion 312a of the rail channel member 312, and the channel C is fixed to the rail channel member 312. The screw 7 may be, for example, a set screw.

[0074] Next, the fixing of the channel C by the channel fixing metal fitting 1B will be described with reference to FIG. 6(B).

[0075] First, the end of the channel C is fixed to the channel fixing portion 323 of the fixing member 32B so that the lip portion C1 of the channel C faces the furring strip fixing portion 2 side (front side) of the channel fixing bracket 1B. The method of fixing the channel C to the channel fixing member 32B (channel fixing portion 323) is as described above. Next, the channel C is fixed to the rail channel material 312 by the rail fixing portion 324 of the fixing member 32B. The method of fixing the channel C to the rail channel material 312 is as described above. The process of attaching the channel C fixed to the channel fixing bracket 1B in this way to the furring strips F1, F2 is omitted because it is the same as the channel fixing bracket 1 of the first embodiment described above.

[0076] (Variation 3-1) FIG. 7 is a perspective view showing a modified example 3-1 of the channel fixing metal fitting 1B according to the third embodiment.

[0077] In this modification 3-1, the configurations of the channel fixing portion 323A and the rail fixing portion 324A differ from those of the channel fixing metal fitting 1B of the third embodiment described above.

[0078] 7, the channel fixing portion 323A of the modified example 3-1 includes a channel contact portion 323c and a pressure plate 323d. The channel contact portion 323c includes a fixing surface 3231a and a pair of contact portions 3232a bent downward from both sides of the fixing surface 3231a so as to be perpendicular to the fixing surface 3231a. The width of the channel contact portion 323c is at least wider than the distance between the lip portions C1 of the channel, and more preferably slightly wider than the width of the channel C. Furthermore, the channel contact portion 323c and the pressure plate 323d are provided with a screw insertion hole 3233 and a screw hole 3234, respectively.

[0079] Then, the pressing plate 323d is inserted from the end of the channel C, the channel abutting portion 323c is positioned so as to abut against the front portion where the opening of the channel C is provided, and the screws 6 inserted into the screw insertion holes 3233 provided in the channel abutting portion 323c are screwed into the screw holes 3234 provided in the pressing plate 323d, thereby fixing the fixing member 32B (channel fixing portion 323A) to the end of the channel C. Note that the pressing plate 323d may be pushed in from the end of the channel C in a state where it is temporarily fixed to the channel abutting portion 323c with the screws 6.

[0080] 7, the rail fixing portion 324A of the modified example 3-1 includes a rail contact portion 324c and a pressure plate 324d. The rail contact portion 324c includes a fixing surface 3241a and a pair of contact portions 3242a bent downward from both sides of the fixing surface 3241a so as to be perpendicular to the fixing surface 3241a. The width of the rail contact portion 324c is at least wider than the distance between the lip portions 312a of the rail channel member 312, and more preferably slightly wider than the width of the rail channel member 312. The rail contact portion 324c and the pressure plate 324d are provided with a screw insertion hole 3243 and a screw hole 3244, respectively.

[0081] Then, the presser plate 324d is inserted from the end of the rail channel 312, the rail abutment portion 324c is positioned so as to abut against the upper surface portion of the rail channel member 312 where the opening is provided, the presser plate 324d and the rail abutment portion 324c are slid, and at any position, the screws 7 inserted into the screw insertion holes 3243 provided in the rail abutment portion 324c are screwed into the screw holes 3244 provided in the presser plate 324d, thereby fixing the channel C to the rail channel member 312. Note that the presser plate 324d may be inserted from the end of the rail channel member 312 in a state where it is temporarily fixed to the rail abutment portion 324c with the screws 7.

[0082] In a configuration like the channel fixing bracket 1B of embodiment 3 described above, in which a channel insertion portion 323a and a screw hole 323b are used as the channel fixing portion 323 and the screw 6 is pressed against the inner wall surface of the back surface C2 of the channel C, there is a risk of the channel C being deformed if the screw 6 is overtightened. In contrast, the channel fixing bracket 1B of modification 3-1 uses a channel abutting portion 323c and a pressing plate 323d inserted into the channel C as the channel fixing portion 323A, and the lip portion C1 is sandwiched and fixed between the pressing piece 323d and the channel abutting portion 323c, so that a load is applied only to the lip portion C1 of the channel C, suppressing the load on other portions of the channel C and making it possible to prevent deformation of the channel C.

[0083] Similarly, in a configuration like the channel fixture 1B of embodiment 3 described above, in which the rail fixing portion 324 uses the rail insertion portion 324a and the screw hole 324b, and the screw 7 is pressed against the inner wall surface of the back portion 312b of the rail channel 312, there is a risk of the rail channel 312 being deformed if the screw 7 is overtightened. In contrast, the channel fixture 1B of modification 3-1 uses the rail abutting portion 324c and the pressure plate 324d inserted into the rail channel 312 as the rail fixing portion 324A, and the lip portion 312a is sandwiched and fixed between the pressure plate 324d and the rail abutting portion 324c. This means that a load is applied only to the lip portion 312a of the rail channel 312, suppressing the load on other portions of the rail channel 312 and making it possible to prevent deformation of the rail channel 312.

[0084] Regarding the fixing of the channel C by the channel fixing bracket 1B of the modified example 3-1, since it is the same as the channel fixing bracket 1 of the above-mentioned embodiment 1, except for the method of fixing the channel C by the channel fixing portion 323A and the method of fixing the channel C to the rail channel material 312 by the rail fixing portion 324A, a detailed description will be omitted.

[0085] (Variation 3-2) FIG. 8 is a perspective view showing a modified example 3-2 of the channel fixing metal fitting 1B according to the third embodiment.

[0086] Channel fixing bracket 1B of modified example 3-2 differs from channel fixing bracket 1B of embodiment 3 described above (see FIG. 6 ) in that fixing member 32B is formed by combining channel fixing portion 323 of channel fixing bracket 1B of embodiment 3 described above with rail fixing portion 324A of channel fixing bracket 1B of modified example 3-1. The configuration of each part of channel fixing bracket 1B of modified example 3-2 and the fixing of channel C by channel fixing bracket 1B of modified example 3-2 are the same as those for channel fixing bracket 1B of embodiment 3 described above, so a description thereof will be omitted.

[0087] The rail fixing portion 324 of the channel fixing metal fitting 1B of the third embodiment described above may be combined with the channel fixing portion 323A of the channel fixing metal fitting 1B of the modified example 3-1 to form a fixing member 32B (not shown).

[0088] As explained above, according to the channel fixing bracket 1B of this embodiment, like the channel fixing bracket 1 of embodiment 1, it is possible to install the channel C at any position in the depth direction of the furring strips F1, F2, and thereby it is possible to provide a channel fixing bracket 1B that is highly versatile.In addition, the rail portion 31 is a rail channel material 312 that extends in the depth direction of the furring strips F1, F2, and the fixing member 32B for attaching the channel C to the rail channel material 312 is slidably attached to the rail channel material.Therefore, unlike when the channel C is attached with screws or bolts, the attachment position of the channel is not limited to the position or size of the hole for inserting the screw or bolt, and it is possible to adjust the position in the depth direction more accurately and easily.

[0089] Furthermore, according to the channel fixing bracket 1B of this embodiment, the channel fixing portion 323 provided on the fixing member 32B has a channel insertion portion 323a that is inserted into the channel and a screw hole 323b provided in the channel insertion portion, and the channel insertion portion 323a is screwed into the screw 6 and pressed against the lip portion C1 of the channel C to fix it, which improves workability and allows the channel fixing bracket 1B to be easily attached to the channel C.

[0090] Furthermore, according to the channel fixing fitting 1B of this embodiment, the channel fixing portion 323 provided on the fixing member 32B comprises a channel abutment portion 323c that abuts against the front portion where the opening of the channel C is provided, and a pressure plate 323d that is housed within the channel C, and the lip portion C1 of the channel C is sandwiched and fixed between the pressure plate 323d and the channel abutment portion 323c, so that a load is applied only to the lip portion C1, suppressing the load on other parts of the channel C and making it possible to prevent deformation of the channel C, etc.

[0091] Furthermore, according to the channel fixing bracket 1B of this embodiment, the rail fixing portion 324 provided on the fixing member 32B has a rail insertion portion 324a that is inserted into the rail channel material 312, and a screw hole 324b provided in the rail insertion portion 324a, and the rail insertion portion 324a is screwed into the screw 7 and pressed against the lip portion 312a of the rail channel material 312 to fix it, which improves workability and allows the channel C to be easily attached to the rail channel material 312.

[0092] Furthermore, according to the channel fixing bracket 1B of this embodiment, the rail fixing portion 324 provided on the fixing member 32B comprises a rail abutment portion 324c that abuts against the upper surface portion of the rail channel material 312 where the opening is provided, and a pressure plate 324d that is housed within the rail channel material 312, and the lip portion 312a of the rail channel material 312 is sandwiched and fixed between the pressure plate 324d and the rail abutment portion 324c, so that a load is applied only to the lip portion 312a, and loads on other portions of the rail channel material 312 are suppressed, making it possible to prevent deformation of the rail channel material 312, etc.

[0093] Although the embodiments of the present invention have been described above, the specific configuration is not limited to the above embodiments, and the present invention also includes design changes within the scope of the present invention. For example, in the above embodiments, the opening side of the channel C faces forward, but the opening side may face sideways or backward. In this case, the shape of the steel material fixing portion 3 must be appropriately changed depending on the orientation of the opening side of the channel C.

[0094] Also, although the fixing of the channel C to the horizontal furring strips has been described, it is also applicable to the case where the channel C is fixed between a pair of vertical furring strips. [Explanation of symbols]
