Effect of the Invention

[0012] Next, the effects of the present invention will be described with reference to the drawings. Note that the reference symbols in the parentheses are those of the embodiments described below, but the present invention is not limited thereto.

[0013] According to the invention of claim 1, when the insertion portions (22a, 22b) of the first member (2) are inserted into the guide portions (32a, 32b) of the second member (3), the first member (2) and the second member (3) are prevented from shifting left and right, so there is no need to fasten the first top surface portion (22) and the second top surface portion (32) together with bolts.

[0014] Furthermore, since the first top surface portion (22) and the second top surface portion (32) are not fastened together by bolts, when adjusting the width (W) between the first member (2) and the second member (3) to match the shape of the seam portion (H), there is no need to take the trouble of temporarily removing the bolts fastening the top surfaces together, as was done in the past.

[0015] Therefore, according to the present invention, the mounting bracket can be made to require less work when installed on a grooved folded-plate roof.

[0016] According to the device of claim 2, the mounting bracket can be easily manufactured.

[0017] According to the invention of claim 3, the bottom surface portion has three surfaces, namely, the inclined portion (21a, 31a), the vertical portion (21b, 31b), and the return portion (21c, 31c). Therefore, there are many parts that can abut against the seam-type folded-plate roof (R) and the seam portion (H). Moreover, since the three surfaces, namely, the inclined portion (21a, 31a), the vertical portion (21b, 31b), and the return portion (21c, 31c), are all formed to extend upward, the bottom surface portion can abut against the seam-type folded-plate roof (R) and the seam portion (H) over a wide range (L) in the vertical direction. Therefore, it can be stably installed on seam-type folded-plate roofs (R) and seam portions (H) of various shapes.

[0018] According to the invention of claim 4, various structures can be installed on the grooved-plate roof (R).

[0019] According to the invention of claim 5, the mounting bracket can be used in a variety of ways. For example, when attaching a long board extending upward to a grooved folded-plate roof (R), it can be supported at two points, so the attached long board will not rotate. It can also be used in other ways as needed, such as passing a cable through the bolt hole. Furthermore, the mounting bracket can be made lighter. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] Hereinafter, an embodiment of a mounting bracket according to the present invention will be described in detail with reference to the drawings. In the following description, when directions such as up, down, left and right are indicated, they refer to the up, down, left and right directions indicated by arrows in the drawings.

[0022] <Overview of mounting brackets> As shown in Fig. 1(a), a mounting bracket 1 according to this embodiment is installed in a seam H of a seam-type folded-plate roof R. This mounting bracket 1 is composed of a first member 2 and a second member 3. The first member 2 and the second member 3 will be described below.

[0023] <First component> First, a description will be given of the first member 2. As shown in Fig. 1(b), the first member 2 is formed in a U-shape by a first bottom surface portion 21 that abuts against the seam portion H, a first top surface portion 22 that faces the first bottom surface portion 21, and a first side surface portion 23 that connects the first bottom surface portion 21 and the first top surface portion 22.

[0024] First, as shown in FIG. 1(b), the first bottom surface portion 21 includes an inclined portion 21a, a vertical portion 21b, and a return portion 21c. As shown in FIG. 1(b), the inclined portion 21a extends from the lower end of the first side surface portion 23. More specifically, as shown in FIG. 1(b), the inclined portion 21a extends upwardly at an incline such that an angle 21d formed by the inclined portion 21a and the first side surface portion 23 is an acute angle (see also FIG. 2(a)). As shown in FIG. 1(b), the vertical portion 21b extends vertically upward from the other end of the inclined portion 21a (see also FIG. 2(a)). As shown in FIG. 1(b), the return portion 21c extends toward the first side surface portion 23, with one end connected to the other end of the vertical portion 21b. In this embodiment, the return portion 21c has a curved surface that is convex toward the seam portion H (see FIG. 2(a)).

[0025] As described above, the first bottom surface portion 21 has three surfaces, the inclined portion 21a, the vertical portion 21b, and the return portion 21c. In this way, the first bottom surface portion 21 has many portions that come into contact with the grooved folded-plate roof R or the grooved portion H. Moreover, since the three surfaces, the inclined portion 21a, the vertical portion 21b, and the return portion 21c, all extend upward, the first bottom surface portion 21 can come into contact with the grooved folded-plate roof R or the grooved portion H over a wide range in the vertical direction (see L shown in FIG. 2(a)). This point will be explained in comparison with a conventional mounting fixture using FIG. 2.

[0026] First, the conventional mounting bracket 1A and mounting bracket 1B will be described. As shown in FIG. 2(b), the first bottom surface portion 21A of the conventional mounting bracket 1A has only two surfaces, a horizontal surface 21aA and a vertical surface 21bA. Moreover, the range LA in the vertical direction in which the bracket can abut against the grooved folded-plate roof R or the grooved portion H is narrow. For this reason, as shown in FIG. 2(b), when the grooved portion H is clamped using the conventional mounting bracket 1A, the tip of the vertical surface 21bA abuts against the grooved portion H, but the horizontal surface 21aA does not abut against the grooved folded-plate roof R (the same is true for the second bottom surface portion 31A, as shown in FIG. 2(b)). Therefore, the grooved folded-plate roof R cannot support the mounting bracket 1A from below, which causes the mounting bracket 1A to wobble.

[0027] Also, as shown in FIG. 2(c), the first bottom surface portion 21B of another conventional mounting bracket 1B can be considered to have three surfaces: the first horizontal surface 21aB, the vertical surface 21bB, and the second horizontal surface 21cB. However, the vertical range LB in which it can abut against the grooved folded-plate roof R or the grooved portion H is still narrow. For this reason, as shown in FIG. 2(c), when the grooved portion H is clamped using another conventional mounting bracket 1B, the corner formed by the second horizontal surface 21cB and the vertical surface 21bB abuts against the grooved portion H, but the first horizontal surface 21aB does not abut against the grooved folded-plate roof R (the same is true for the second bottom surface portion 31B, as shown in FIG. 2(c)). Therefore, the grooved folded-plate roof R cannot support the mounting bracket 1B from below, which causes the mounting bracket 1B to wobble.

[0028] On the other hand, the mounting bracket 1 shown in FIG. 2(a) has three surfaces: an inclined portion 21a, a vertical portion 21b, and a return portion 21c. In addition, since the three surfaces of the inclined portion 21a, the vertical portion 21b, and the return portion 21c all extend upward, the vertical range L in which the mounting bracket 1 can abut against the grooved folded-plate roof R or the grooved portion H is wide (the length from the corner 21d to the upper end of the return portion 21c is long). For this reason, as shown in FIG. 2(a), when the grooved portion H is clamped using the mounting bracket 1, the bottom surface portion 21 (the corner 21d formed by the inclined portion 21a and the first side surface portion 23) abuts against the grooved folded-plate roof R. Therefore, since the grooved folded-plate roof R supports the mounting bracket 1 from below, the mounting bracket 1 can be stably attached.

[0029] In this way, the first bottom surface portion 21 of the mounting bracket 1 of this embodiment shown in Figure 2(a) is structured to be more stably attached to the grooved-plate roof R than the conventional first bottom surface portion 21A and first bottom surface portion 21B.

[0030] 1(b), the first top surface portion 22 has a U-shape in plan view that opens toward the second member 3 due to a notch K provided on the first top surface portion 22. This forms a pair of left and right insertion portions 22a, 22b (a pair of left and right insertion portions as viewed from the second member 3) that extend toward the second member 3.

[0031] Finally, as shown in Fig. 1(b), the first side surface portion 23 is provided with a bolt hole 23a. This bolt hole 23a is formed on the same axis as the bolt hole 33a provided in the second side surface portion 33 of the second member 3 (see line S shown in Fig. 1(b)).

[0032] In addition, as shown in FIG. 1(b), the first side portion 23 has another bolt hole 23b formed below the bolt hole 23a. In this way, since the first side portion 23 has a plurality of bolt holes formed in a vertical line, the mounting bracket 1 can be used in a variety of ways. For example, a long board (not shown) extending perpendicularly to a grooved folded-plate roof R (see FIG. 1(a)) can be stably attached to the mounting bracket 1. That is, if the first side portion 23 only has the bolt hole 23a, even if the long board (not shown) is fixed to the bolt hole 23a using a bolt, there is a risk that the long board (not shown) will rotate around the bolt hole 23a. However, since the mounting bracket 1 has the bolt holes 23a and 23b, the long board (not shown) can be supported at two points, so there is no risk of the long board rotating. In addition, it can be used in a manner as needed, such as passing a cable through this bolt hole 23b. Furthermore, the mounting bracket can be made lighter.

[0033] The first member 2 is composed of the first bottom surface portion 21, the first top surface portion 22, and the first side surface portion 23 as described above (see FIG. 1(b)).

[0034] <Second member> Next, the second member 3 will be described. As shown in Fig. 1(a), the second member 3 is formed in a U-shape by a second bottom surface portion 31 that abuts against the seam portion H, a second top surface portion 32 that faces the second bottom surface portion 31, and a second side surface portion 33 that connects the second bottom surface portion 31 and the second top surface portion 32.

[0035] 1(b), the second bottom surface portion 31 includes an inclined portion 31a, a vertical portion 31b, and a return portion 31c. The configurations of the inclined portion 31a, the vertical portion 31b, and the return portion 31c are the same as those of the inclined portion 21a, the vertical portion 21b, and the return portion 21c of the first member 2, and therefore will not be described.

[0036] Next, as shown in FIG. 1(b), the second top surface portion 32 includes a pair of left and right guide portions 32a, 32b. The guide portions 32a, 32b are for inserting the insertion portions 22a, 22b provided on the first top surface portion 22 of the first member 2. In this embodiment, the guide portions 32a, 32b are formed by cutting and bending. That is, two cuts are formed on each of the left and right sides of the second top surface portion 32 (the left and right sides as viewed from the first top surface portion 22), and the remaining cut portions are bent downward to form the guide portions 32a, 32b. Since the guide portions are formed by cutting in this manner, it is easy to form the guide portions.

[0037] A gap equal to or larger than the plate thickness of the insertion portions 22a, 22b is formed between the guide portions 32a, 32b and the back surface 32c of the second top surface portion 32. This allows the first member 2 to freely slide in the opposing direction (the front-rear direction shown in FIG. 1(b)) relative to the second member 3. Therefore, the width W (see FIG. 1(b)) of the space between the first bottom surface portion 21 and the second bottom surface portion 31 can be easily adjusted according to the shape of the seam portion H to be clamped.

[0038] 1(b), the second top surface portion 32 is formed with two different sized bolt holes 32d, 32e. Since bolt holes of different sizes are formed in this way, by using the mounting bracket 1, various members can be attached to the grooved folded-plate roof R (see FIG. 1(a)) for the installation of a structure.

[0039] When the first top surface portion 22 and the second top surface portion 32 are placed together, the bolt holes 32d, 32e overlap the cutout portion K. Therefore, there is no need to form bolt holes in the first top surface portion 22 at locations corresponding to the bolt holes 32d, 32e, which makes manufacturing easier.

[0040] Finally, the second side surface portion 33 is provided with a bolt hole 33a. This bolt hole 33a is formed on the same axis as the bolt hole 23a provided in the first side surface portion 23 of the first member 2 (see line S shown in FIG. 1(b)).

[0041] 1(b), another bolt hole 33b is formed below the bolt hole 33a in the second side surface portion 33. The advantages of the bolt hole 33b in the second side surface portion 33 are similar to those of the bolt hole 23b in the first side surface portion 23 (see FIG. 1(b)), and therefore will not be described here.

[0042] The second member 3 is composed of the second bottom surface portion 31, the second top surface portion 32, and the second side surface portion 33 as described above (see FIG. 1(b)).

[0043] <Installation method> A worker can install the mounting bracket 1 composed of the first member 2 and the second member 3 as described above on a grooved folded-plate roof R as follows.

[0044] First, the worker places the first member 2 and the second member 3 opposite each other, sandwiching the seam portion H of the seam-type folded-plate roof R (see FIG. 1(a)). Then, insert the insertion portion 22a into the guide portion 32a and the insertion portion 22b into the guide portion 32b so that the first top surface portion 22 of the first member 2 and the second top surface portion 32 of the second member 3 overlap (see FIGS. 1(a) and 1(b)). Once this work is completed, even if the worker releases his or her hands from the mounting bracket 1, the first member 2 and the second member 3 will not shift left or right from each other.

[0045] The first top surface portion 22 of the first member 2 and the second top surface portion 32 of the second member 3 are not fastened with bolts. Therefore, the width W (see FIG. 1(b)) of the space between the first bottom surface portion 21 of the first member 2 and the second bottom surface portion 31 of the second member 3 can be easily adjusted to match the shape of the seam portion H by simply sliding the first member 2 and the second member 3 back and forth relative to each other.

[0046] Next, the worker inserts the bolt B through the bolt hole 23a formed in the first side surface portion 23 of the first member 2 and the bolt hole 33a formed in the second side surface portion 33 of the second member 3, and fastens the washer Z and the nut N to the bolt B from the second member 3 side (see Figs. 1(a) and 1(b)). As a result, the first bottom surface portion 21 of the first member 2 and the second bottom surface portion 31 of the second member 3 tightly hold the seam portion H of the seam-type folded-plate roof R.

[0047] The worker then uses the bolt holes 32d and 32e in the second top surface portion 32 of the second member 3, the bolt holes 33a and 33b in the second side surface portion 33, and the bolt hole 23a in the first side surface portion 23 to attach various members for installing the structure to the grooved folded plate roof R. When using the bolt hole 33a provided in the second side surface portion 33 of the second member 3, it is necessary to first attach the members for installing the structure to the bolt B inserted into the bolt hole 33a, and then fasten the washer Z and the nut N to the bolt B.

[0048] According to the present embodiment described above, when the insertion portions 22a, 22b of the first member 2 are inserted into the guide portions 32a, 32b of the second member 3, the first member 2 and the second member 3 are prevented from shifting left and right, so there is no need to fasten the first top surface portion 22 and the second top surface portion 32 together with bolts.

[0049] Furthermore, since the first top surface portion 22 and the second top surface portion 32 are not fastened together by bolts, when adjusting the space width W (see Figure 1 (b)) between the first bottom surface portion 21 of the first member 2 and the second bottom surface portion 31 of the second member 3 to match the shape of the seam portion H, there is no need to go to the trouble of first removing the bolts fastening the top surfaces together, as was done in the past.

[0050] As described above, according to this embodiment, the mounting bracket 1 can be installed on a grooved folded-plate roof R with less labor required.

[0051] <Description of Modifications> The mounting fixture shown in this embodiment is merely an example, and various modifications and alterations are possible within the scope of the gist of the present invention described in the claims of the utility model registration. For example, in this embodiment, the guide parts 32a and 32b (see FIG. 1(b)) are provided by bending the left and right sides of the second top surface part 32 downward by bending. However, the guide parts may be provided by a different method. For example, the guide parts may be provided by bending the left and right sides of the second top surface part 32 upward instead of downward. However, it is preferable to provide the guide parts 32a and 32b (see FIG. 1(b)) by bending them downward as in this embodiment, because it is easier to place a heavy object on the second top surface part 32.
