Mode for Carrying Out the Invention

[0009] Hereinafter, the mounting bracket and the method for manufacturing a building using the mounting bracket will be described with reference to the drawings as appropriate. For ease of explanation, in the embodiment, as shown in FIG. 2, the horizontal direction orthogonal to the longitudinal direction L of the mounting bracket 1 with respect to the building member (C-shaped steel 20) is the left-right (width) direction W, and the vertical direction is the up-down (height) direction H.

[0010] As shown in FIG. 1, the mounting bracket 1 of the embodiment is used in a method for manufacturing a building in which a C-shaped steel 20 as a building member is attached to an H-shaped steel 10 as a member to be attached. First, the H-shaped steel 10 as a member to be attached to which the mounting bracket 1 is attached in the embodiment is long and mainly used for the building frame and support structure of the building. The H-shaped steel 10 has a vertical wall-shaped web 12, a flat upper flange 11 connected to the upper edge of the web 12, and a flat lower flange 13 connected to the lower edge of the web 12, and is formed so that the longitudinal sectional shape is an H shape.

[0011] In addition, the C-shaped steel 20 as a building member of the embodiment has a lip groove-shaped steel having a C-shaped longitudinal sectional shape. The C-shaped steel 20 is made of a material such as a lightweight steel frame that can be drilled with screws 5 so that the mounting bracket 1 can be fixed by screwing. Furthermore, a flat wall material (not shown) is arranged below the C-shaped steel member 20 of the embodiment. These wall materials include a pair of runners arranged vertically, a plurality of studs erected between the upper and lower runners, and a facing material attached to the side surfaces of the runners and studs. The runners and studs are made of grooved or square steel. The upper runner of the C-shaped steel member 20 is attached with the groove opening facing downward. Thereby, the wall material is attached to the H-shaped steel member 10 of the building via the C-shaped steel member 20 and the mounting bracket 1.

[0012] Next, the configuration of the mounting bracket 1 of the embodiment of the present invention will be described. In the embodiment, as shown in FIG. 1, a pair of left and right mounting brackets 1 are respectively provided at one end 10a or the other end 10b of the lower flange 13 of the H-shaped steel member 10. As shown in FIG. 3(a) or (c), the mounting bracket 1 of the embodiment is formed symmetrically left and right with the same shape and is configured to be provided at either one end 10a or the other end 10b.

[0013] And each mounting bracket 1 includes a bracket lower part 2 disposed below the H-shaped steel member 10 to which the C-shaped steel member 20 is fixed, and a bracket upper part 3 continuously provided on the bracket lower part 2. Among these, the bracket upper part 3 is disposed above the lower flange 13 of the H-shaped steel member 10 by bypassing one end 10a or the other end 10b of the H-shaped steel member 10 (see FIG. 2).

[0014] As shown in FIG. 3(b) or (d), the mounting bracket 1 is formed in a substantially U-shape in side view, and a recess provided in the middle part in the vertical direction is open toward the H-shaped steel member 10 side. Then, the inside of this recess is inserted into each end 10a, 10b of the lower flange 13.

[0015] Further, the lower metal fitting 2 has a pair of lower side wall portions 2a, 2a which are spaced apart from each other (see Fig. 3(c)). Furthermore, the upper metal fitting 3 has a pair of upper side wall portions 3a, 3a provided continuously with the pair of lower side wall portions 2a, 2a, and an upper wall portion 3b connecting the upper ends of the pair of upper side wall portions 3a, 3a. And the interval W1 between the pair of upper side wall portions 3a, 3a is formed to be smaller than the interval W2 between the pair of lower side wall portions 2a, 2a (see Fig. 2).

[0016] As shown in Fig. 2, the interval between the pair of lower side wall portions 2a, 2a is equivalent to the width dimension W3 of the C-shaped steel member 20. A plurality of screw insertion holes 2f are formed in the lower side wall portion 2a. And screws 5 are respectively inserted into these screw insertion holes 2f and fixed to the side surfaces 20c, 20d of the C-shaped steel member 20 by screwing. In this way, when the lower metal fitting 2 sandwiches the C-shaped steel member 20 between the pair of lower side wall portions 2a and is fixed by screwing, each lower side wall portion 2a can abut against the side surfaces 20c, 20d on both the left and right sides of the C-shaped steel member 20 and be fixed in a stable state.

[0017] The lower metal fitting 2 also includes a pair of extending portions 2d which extend inward from the upper end portions 2c of the pair of lower side wall portions 2a respectively and are continuous with the lower end portions 3c of the pair of upper side wall portions 3a. The extending portion 2d of the embodiment has a bent shape at two locations between the upper end portion 2c of the lower side wall portion 2a and the extending portion 2d, and between the extending portion 2d and the lower end portion 3c of the upper side wall portion 3a. Therefore, the lower metal fitting 2 can support the upper metal fitting 3 on the upper surface of the C-shaped steel member 20 without causing it to deform and fall to the left and right in the width direction.

[0018] Furthermore, as shown in FIG. 2, the extending portion 2d can be brought into surface contact with the upper surface of the C-shaped steel member 20 by two bending shapes. Therefore, in the mounting bracket 1 of the embodiment, the lower side wall portion 2a of the bracket lower part 2 is brought into contact with the left and right side surfaces of the C-shaped steel member 20 to regulate the mounting position in the width direction W. In addition, the mounting bracket 1 can regulate the mounting position in the vertical direction H by bringing the extending portion 2d of the bracket lower part 2 into contact with the upper surface of the C-shaped steel member 20. Therefore, when the mounting bracket 1 is placed so as to straddle the upper part of the C-shaped steel member 20, it is positioned at a desired position vertically and horizontally. Further, the mounting bracket 1 supports the bracket upper part 3 vertically and horizontally by bringing the two orthogonal surfaces of the pair of lower side wall portions 2a and the extending portion 2d into surface contact with the C-shaped steel member 20. For this reason, when screwing, the bracket upper part 3 does not tilt as in the conventional case. Therefore, the bracket lower part 2 can be accurately attached to the C-shaped steel member 20 in a more stable state.

[0019] The bracket lower part 2 is provided with a pair of pressure receiving portions 2e. As shown in FIG. 3(c), the pressure receiving portions 2e extend inward from the upper end portions 2c of the pair of lower side wall portions 2a, respectively. The bracket lower part 2 is formed to be flat in the width direction W with a gap therebetween in a state where the inner end faces face each other. The pressure receiving portion 2e of the embodiment can be brought into surface contact with the upper surface of the C-shaped steel member 20 together with the extending portion 2d when the bracket lower part 2 of the mounting bracket 1 is attached to one end side 20a or the other end side 20b of the C-shaped steel member 20 in advance. For this reason, for example, the possibility that the mounting bracket 1 falls inward due to the weight of the bolt member 4b is reduced. Therefore, screwing can be easily performed in a more stable state, and the screwed mounting bracket 1 is accurately fixed at a desired position in a state straddling one end side 20a or the other end side 20b of the C-shaped steel member 20.

[0020] Furthermore, the mounting bracket 1 is provided with a clamping portion 4. The clamping portion 4 includes a female screw portion 4a provided on the upper wall portion 3b, a bolt member 4b that is installed in the female screw portion 4a and is movable forward and backward in the vertical direction H with respect to the member to be mounted, and a lock nut 4c that is screwed onto the bolt member 4b. The upper wall portion 3b of the embodiment is provided with a female screw portion 4a that communicates vertically in a portion extending inward from the upper side wall portion 3a of the upper portion 3 of the bracket.

[0021] Therefore, for example, when the bolt member 4b of the clamping portion 4 of the embodiment is advanced downward from the upper portion 3 of the bracket, the C-shaped steel member 20 can be clamped in cooperation with the lower portion 2 of the bracket. Thereby, the mounting bracket 1 can be attached to the lower flange 13 of the H-shaped steel member together with the C-shaped steel member 20. At this time, the pressure receiving portion 2e can receive the tightening force applied to the end portion of the lower flange 13 directly below the bolt member 4b. Therefore, a stronger and more accurate attachment can be performed.

[0022] Next, a manufacturing method of a building in which the C-shaped steel member 20 is attached to one end portion 10a and the other end portion 10b of the H-shaped steel member 10 using the mounting bracket 1 of the embodiment shown in FIG. 4 will be described here in accordance with the attachment order. In the manufacturing method of the building according to the embodiment, first, as shown in FIG. 4(a), the lower portion 2 of the first mounting bracket 1 is preliminarily fixed to one end side 20a of the C-shaped steel member 20 with screws 5.

[0023] At this time, when the first mounting bracket 1 straddles the one end side 20a, the extension portion 2d and the pressure receiving portion 2e are in surface contact with the upper surface of the C-shaped steel member 20 with their respective flat lower surface sides, and the first mounting bracket 1 is placed in a stable state. Furthermore, the pair of lower side wall portions 2a, 2a of the lower portion 2 of the bracket sandwich the C-shaped steel member 20 therebetween and are in contact with the left and right side surfaces 20c, 20d from the left and right. Therefore, the mounting bracket 1 is fixed to the C-shaped steel member 20 with screws in a stable state. Therefore, the first mounting bracket 1 can be easily fixed to one end side 20a of the C-shaped steel member 20 with accurate mounting accuracy without being deformed or tilted as in the conventional case.

[0024] Next, the first mounting fitting 1 slides from the right side to the left side in FIG. 4 and positions the upper part 3 of the fitting above the end 10a on one side of the H-shaped steel member 10. As shown in FIG. 4(b), the first mounting fitting 1 rotates the bolt member 4b of the clamping portion 4 to move the lower end downward and clamps the H-shaped steel member 10 between the pressure receiving portion 2e. At this time, the bolt member 4b can be advanced and retracted as appropriate to adjust the clamping force. When the mounting fitting 1 is temporarily fixed to the end of the lower flange 13, the C-shaped steel member 20 can be temporarily arranged so as not to fall below the H-shaped steel member 10. Thus, the operator can perform the mounting operation of the next second mounting fitting 1 with both hands.

[0025] The second mounting fitting 1 is arranged at the end 10b on the other side of the H-shaped steel member 10. At this time, the second mounting fitting 1 is slid from the left side to the right side in FIG. 4. Thereby, the pressure receiving portion 2e of the mounting fitting 1 is inserted into the gap 30 formed between the lower surface side of the end 10b on the other side of the H-shaped steel member 10 and the upper surface side of the other end side 20b of the C-shaped steel member 20.

[0026] Then, as shown in FIG. 4(c), the bolt member 4b of the second mounting fitting 1 is tightened to temporarily fix the mounting fitting 1 to the end of the lower flange 13. In this way, since the H-shaped steel member 10 is clamped by the clamping portion 4, the second mounting fitting 1 is temporarily arranged. Next, the lower part 2 of the second mounting fitting 1 is screwed and fixed to the other end side 20b of the C-shaped steel member 20 with screws 5. At this time, there is no possibility that the second mounting fitting 1 will tilt as in the conventional case. Therefore, the second mounting fitting 1 can be screwed and fixed in a stable state to the left and right side surfaces 20c, 20d (see FIG. 1) of the other end side 20b at a desired position.

[0027] Further, with the C-shaped steel member 20 temporarily arranged horizontally, for the first mounting bracket 1 and the second mounting bracket 1, the bolt members 4b of the respective clamping portions 4 are fully tightened. After the full tightening, locking is performed using a lock nut 4c screwed onto the bolt member 4b. Thereby, the upper bracket portion 3 can clamp the lower flange 13 of the H-shaped steel member 10 together with the lower bracket portion 2 by the clamping portion 4. That is, the upper bracket portion 3 has the distance W1 between the upper side wall portions 3a, 3a set to be smaller than the distance W2 between the lower side wall portions 2a, 2a, improving rigidity. For this reason, even when the force for tightening the bolt member 4b acts as a reaction force, deformation of the mounting bracket 1 is suppressed. Also, when fixing the C-shaped steel member 20, as shown in FIG. 2, the pressure receiving portion 2e of the mounting bracket 1 is sandwiched between the lower flange 13 of the H-shaped steel member 10 and the upper surface of the side surface portion 22 of the C-shaped steel member 20. For this reason, the possibility that the upper bracket portion 3 is deformed so as to fall to the left and right or front and back in the width direction W can be further reduced, improving the mounting accuracy.

[0028] As described above, in the mounting bracket 1 of the embodiment, the distance W1 between the upper side wall portions 3a is set to be smaller than the distance W2 between the lower side wall portions 2a. For this reason, when the mounting bracket 1 is mounted on the C-shaped steel member 20 in advance, it is stably placed so as to straddle. Therefore, there is no possibility of being mounted in an inclined manner as in the prior art, and the mounting accuracy when screwing is good. Also, when attaching the C-shaped steel member 20 to the H-shaped steel member 10, since the rigidity of the upper bracket portion 3 is improved, deformation such as falling in the front, rear, left, and right directions and deformation such that the upper wall portion 3b bends in the out-of-plane direction are less likely to occur. Therefore, the mounting bracket 1 can accurately and firmly fix the C-shaped steel member 20 to the H-shaped steel member 10. Furthermore, in the construction method of a building using the mounting bracket 1 of the embodiment, construction can be performed using a plurality of mounting brackets 1 having the same shape, such as the first mounting bracket 1 and the second mounting bracket 1. Therefore, the member efficiency is good.

[0029] Therefore, the mounting bracket 1 of the embodiment can exhibit practically useful effects such as improving the mounting accuracy and easily attaching the construction member to the member to be attached.

[0030] As described above, the mounting bracket 1 of the embodiment is for attaching the C-shaped steel member 20 as a construction member to the H-shaped steel member 10 as a member to be attached. The mounting bracket 1 is disposed below the member to be attached, and includes a lower bracket portion 2 on which the construction member is fixed, and an upper bracket portion 3 that is continuously provided with the lower bracket portion 2, bypasses the end portion of the member to be attached, and is disposed above the member to be attached. Further, the mounting bracket 1 includes a clamping portion 4 that is provided on the upper bracket portion 3 and clamps the member to be attached in cooperation with the lower bracket portion 2. The lower bracket portion 2 has a pair of lower side wall portions 2a, 2a that are spaced apart from each other. The upper bracket portion 3 has a pair of upper side wall portions 3a, 3a that are continuously provided with the pair of lower side wall portions 2a, 2a, and an upper wall portion 3b that connects the upper ends of the pair of upper side wall portions 3a, 3a. And, the interval W1 between the pair of upper side wall portions 3a, 3a is smaller than the interval W2 between the pair of lower side wall portions 2a, 2a.

[0031] According to this mounting bracket 1, the upper wall portion 3b whose both sides are connected by the pair of upper side wall portions 3a having a smaller interval W1 than the interval W2 between the lower side wall portions 2a, 2a can improve the rigidity in the out-of-plane direction. For this reason, the deformation of the upper bracket portion 3 is suppressed, and when the member to be attached is clamped by the clamping portion 4 in cooperation with the lower bracket portion 2, the mounting accuracy is improved and the construction member can be easily attached to the member to be attached.

[0032] Further, the lower bracket portion 2 includes a pair of extending portions 2d that extend inward from the upper end portions 2c of the pair of lower side wall portions 2a and are continuous with the lower end portions 3c of the pair of upper side wall portions 3a. For this reason, it bends at two locations between the upper end portion 2c of the lower side wall portion 2a and the extending portion 2d, and between the extending portion 2d and the lower end portion 3c of the upper side wall portion 3a, and the rigidity of the mounting bracket 1 can be further improved. Further, by bringing the extending portion 2d into contact with the upper surface of the construction member, the lower bracket portion 2 can be attached to the construction member in a more stable state.

[0033] Furthermore, specifically, in the mounting bracket 1 of the embodiment, due to two bends, two continuously orthogonal planes, namely a pair of lower side wall portions 2a and extension portions 2d, are formed. Therefore, by making surface contact with the C-shaped steel member 20 respectively, the positioning accuracy is improved, and the upper part 3 of the bracket does not tilt as in the prior art. Thus, the lower part 2 of the bracket can be more securely attached to the construction member in a more stable state.

[0034] Furthermore, the lower part 2 of the bracket includes a pair of pressure-receiving portions 2e that extend inward from the upper end portions 2c of the pair of lower side wall portions 2a respectively and are arranged between the construction member and the member to be attached. Therefore, by bringing the pair of pressure-receiving portions 2e into contact with the upper surface of the construction member, the lower part 2 of the bracket can be attached to the construction member in a more stable state. Also, in the attached state, a pair of pressure-receiving portions 2e arranged between the construction member and the member to be attached are clamped between the construction member and the member to be attached. Thus, the mounting bracket 1 and the construction member can be more stably attached to the member to be attached.

[0035] And the clamping portion 4 includes a female screw portion 4a provided on the upper wall portion 3b and a bolt member 4b that is installed on the female screw portion 4a and can move forward and backward with respect to the member to be attached. Therefore, the clamping portion 4 can move the bolt member 4b forward and backward with the female screw portion 4a provided on the upper wall portion 3b to temporarily arrange or fix the mounting bracket 1 to the member to be attached.

[0036] Also, the distance W2 between the pair of lower side wall portions 2a is equal to the width dimension W3 of the construction member, and the pair of lower side wall portions 2a are respectively fixed to both side surfaces of the construction member. Therefore, the lower part 2 of the bracket can sandwich the construction member between the pair of lower side wall portions 2a and stably fix the lower side wall portions 2a on the left and right to the respective side surfaces 20c and 20d. Thus, the mounting bracket 1 can further stably improve the mounting accuracy to the member to be attached.

[0037] Furthermore, the method for manufacturing a building attaches C-shaped steel members 20 to one end portion 10a and the other end portion 10b of an H-shaped steel member 10 using mounting brackets 1. The method for manufacturing a building includes a step of fixing the bracket lower portion 2 of the first mounting bracket 1 to one end side of the C-shaped steel member 20. Also, the method for manufacturing a building includes a step of arranging the bracket upper portion 3 of the first mounting bracket 1 above the upper side of one end portion 10a of the H-shaped steel member 10, clamping the H-shaped steel member 10 with the clamping portion 4, and temporarily arranging the C-shaped steel member 20 below the H-shaped steel member 10. Furthermore, the method for manufacturing a building includes a step of arranging the second mounting bracket 1 at the other end portion 10b of the H-shaped steel member 10 and temporarily arranging the second mounting bracket 1 by clamping the H-shaped steel member 10 with the clamping portion 4. Also, the method for manufacturing a building includes a step of fixing the other end side 20b of the C-shaped steel member 20 to the bracket lower portion 2 of the second mounting bracket 1, and a step of firmly tightening the clamping portion 4 for the first mounting bracket 1 and the second mounting bracket 1.

[0038] In such a method for manufacturing a building, when attaching the C-shaped steel member 20 to the H-shaped steel member 10, the bracket lower portion 2 of the first mounting bracket 1 is fixed in advance to one end side 20a of the C-shaped steel member 20. In this step, the first mounting bracket 1 is accurately fixed to one end side 20a of the C-shaped steel member 20 in a stable state. Therefore, in the step of arranging the bracket upper portion 3 of the first mounting bracket 1 above the upper side of one end portion 10a of the H-shaped steel member 10, when the H-shaped steel member 10 is clamped with the clamping portion 4, the C-shaped steel member 20 is temporarily arranged at a desired position below the H-shaped steel member 10.

[0039] Furthermore, in the step of arranging the second mounting bracket 1 at the other end portion 10b of the H-shaped steel member 10, the second mounting bracket 1 can be easily temporarily arranged by clamping the H-shaped steel member 10 with the clamping portion 4. And in the step of fixing the other end side 20b of the C-shaped steel member 20 to the bracket lower portion 2 of the second mounting bracket 1, the second mounting bracket 1 is accurately fixed to one end side 20a of the C-shaped steel member 20 in a stable state.

[0040] And in the step of firmly tightening with the clamping portion 4, the first mounting bracket 1 and the second mounting bracket 1 firmly tighten their respective clamping portions 4 to firmly attach the C-shaped steel member 20 to a desired position of the H-shaped steel member 10. Specifically, in the embodiment, the distance W1 between the upper wall portions 3a is set to be smaller than the distance W2 between the lower wall portions 2a of the mounting bracket 1, and the upper wall portion 3b whose both sides are connected to the upper ends thereof improves the out-of-plane rigidity. Therefore, the mounting bracket 1 can exhibit sufficient rigidity against the tightening force of the bolt member 4b. Thus, the pair of mounting brackets 1 can firmly attach one end side 20a and the other end side 20b of the C-shaped steel member 20 to the accurate positions below the H-shaped steel member 10.

[0041] Therefore, the mounting bracket of the embodiment and the manufacturing method of the building using the mounting bracket can exhibit practically useful effects such as improving the mounting accuracy and easily attaching the building member to the member to be mounted.

[0042] The present invention is not limited to the above-described embodiments, and various modifications are possible. The above-described embodiments are illustrated for easy understanding and explanation of the present invention, and are not necessarily limited to those having all the configurations described. Also, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. Also, a part of the configuration of each embodiment can be deleted, or other configurations can be added or replaced. Possible modifications to the above embodiments are, for example, as follows.

[0043] In the embodiment, the C-shaped steel member 20 has been described as the building member, but it is not particularly limited thereto. For example, it may be any shape of building member such as other shaped channel members having a U-shaped longitudinal cross-sectional shape, angle members, or square pipe members. Furthermore, the building member of the embodiment has been described by showing the C-shaped steel member 20 for attaching studs of wall materials etc. as the use, but it is not particularly limited thereto.
