Description

[Technical field]

[0001] The present invention relates to a shaped steel support device that is attached to light-gauge shaped steel used as a base material for furring strips, purlins, etc., and that mainly supports electric wires, piping, etc. [Background technology]

[0002] Light-gauge steel used as base materials for buildings includes light-gauge channel steel and lip-gauge steel, and is mainly used for furring strips, purlins, double ceilings, etc.

[0003] The hanging hardware for lip channel steel described in Patent Document 1 is configured to attach a hanging hardware for suspending a hanging bolt to lip channel steel (lightweight steel). That is, this hanging hardware uses a roughly U-shaped gripping member that is attached along the outer shape of the lip channel steel. This gripping member is provided with a pair of locking pieces that lock onto the lip of the lip channel steel, and a bolt hole is drilled in the lower end of the gripping member. Then, a bolt is inserted into this bolt hole to screw a plate welded to the end of the hanging bolt.

[0004] Moreover, the lip channel steel mounting fixture described in Patent Document 2 is a mounting fixture that supports an electric conduit to a lip channel steel. This mounting fixture is provided with a mounting fixture that places and supports an electric conduit on the upper surface of the lip channel steel with the opening facing downward, and is configured to be fixed to the lip side of the lip channel steel.

[0005] On the other hand, a support bracket 100 shown in Fig. 13 is used as a metal fitting for supporting an electric conduit to a light-gauge steel channel. This support bracket 100 is a metal fitting for supporting an electric conduit to a light-gauge steel channel R (light-gauge steel) used as a joist support material. This support bracket 100 is composed of a gripping member 110 and a connecting and locking portion 120.

[0006] The gripping member 110 has an abutment portion 111 that abuts against the web R2 of the light channel steel R, and a locking portion 112 that is previously locked to one flange R1 of the light channel steel R, and a bolt hole 113 is drilled in the gripping member 110 on the lower end side of the abutment portion 111. (Documents for the web R2 are attached.)

[0007] The connecting and locking part 120 is formed as a separate part from the gripping member 110, and is a part that locks to the other flange R1 of the light channel steel R. This connecting and locking part 120 is provided with a locking part 121 having a substantially U-shaped cross section that locks to the flange R1, and a screw hole 122 into which a connecting bolt 200 is screwed. The connecting and locking part 120 is screwed to the gripping member 110 side by the connecting bolt 200 inserted into the bolt hole 113 of the gripping member 110, thereby locking the locking part 121 of the connecting and locking part 120 to the flange R1. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Utility Model Application Publication No. 5-27480 [Patent Document 2] Patent No. 3874700 Summary of the Invention [Problem to be solved by the invention]

[0009] The hanging fittings and support fittings described in Patent Documents 1 and 2 are both fixed using a pair of lips that are bent inward from the flange tip of the lip channel steel. Therefore, it is not possible to support electric conduits, etc., on a light channel steel that does not have a lip.

[0010] On the other hand, the conventional support fitting shown in Fig. 13 is configured to support electric conduits or the like on a light-gauge steel R without a lip. However, there was a problem that the work of attaching this support fitting to the light-gauge steel R required a lot of work. That is, the connecting and locking part 120, which is configured as a separate part from the gripping member 110 of the support fitting, is temporarily fixed by screwing a connecting bolt 200 to the lower end of the gripping member 110. Next, the connecting and locking part 120 in the temporarily fixed state is operated to engage with the end of the flange R1, and while maintaining this engaged state, the connecting and locking part 120 is screwed to the gripping member 110. Therefore, this series of attachment operations required a lot of work.

[0011] Furthermore, since the locking portion 112 formed on the gripping member 110 is formed by bending the tip of the gripping member 110, when a large load is applied to the locking portion 112, the bent portion of the locking portion 112 tends to gradually open, which may reduce the support strength.

[0012] SUMMARY OF THE PRESENT EMBODIMENT The present invention has been made to solve the problems of the related art, and has an object to provide a support for shaped steel which is extremely easy to attach to light-gauge shaped steel and has excellent supporting strength. [Means for solving the problem]

[0013] In order to achieve the above-mentioned object, the first means of the present invention is a support 1 to be attached to the outside of a structural steel, which comprises an engaging portion 10 that engages with one flange R1 of the structural steel, an abutment body 20 that abuts from the engaging portion 10 to the outside of the web R2 of the structural steel, and a crimping and fixing portion 30 that is freely swingable at the end of the abutment body 20 and is crimped and fixed to the end of the other flange R1, and a fixing screw 40 is provided on the abutment body 20 to screw the crimping and fixing portion 30, so that when the fixing screw 40 is tightened, the crimping and fixing portion 30 can swing to the crimping position of the flange R1.

[0014] The second means is a support 1 to be attached to a structural steel, which comprises a contact body 20 that contacts one end side of the width portion of one flange R1 of the structural steel, and a crimping fixing portion 30 that is freely swingable provided on the contact body 20 and can be engaged with the other end of the width portion of the flange R1.

[0015] The third means is provided so that the crimping and fixing portion 30 is swung by a pressing means to the crimping position of the flange R1.

[0016] The abutment body 20 of the fourth means is provided with an abutment piece 22 that abuts against the outer side of the shaped steel on one end side of the width portion of the flange R1.

[0017] The contact body 20 of the fifth means is bent on the outside of one end side of the width portion, and is provided with a connection port 2 for connecting a support member Q on this bent surface.

[0018] The crimping and fixing portion 30 of the sixth means has a bending portion 31 extending freely and bendably from the end of the abutment body 20, a fixing portion 32 extending and bent from the bending portion 31, and a oscillating portion 33 equipped with a crimping portion 35 extending and bent from the fixing portion 32 and crimped to the other flange R1.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0026] The present invention relates to a support bracket 1 which is attached to light channel steel R used, for example, as a base material for furring strips, purlins, etc., to support electric conduits, etc., and which has a connection port 2 to which a support member Q which supports, for example, an electric conduit as a supported member P is connected (see Figure 7).

[0027] The main components of this support fitting 1 are a locking portion 10, a contact body 20, and a crimping and fixing portion 30, which can be integrally formed from a strip-shaped metal plate (see FIG. 1).

[0028] That is, the locking portion 10 is a portion that locks onto one flange R1 of the light channel steel R (see FIG. 4). The locking portion 10 has a pair of bent pieces 11 bent from the left and right side edges on the tip side of the locking portion 10, and a notch 11A formed in each bent piece 11 into which the tip side of one flange R1 is inserted (see FIG. 2). Furthermore, the bent pieces 11 are provided with an abutment piece 11B that abuts against the upper surface of the flange R1 via the notch 11A, and a locking piece 11C that locks onto the inside of the flange R1.

[0029] As shown in Fig. 3, one flange R1 of the light groove steel R is inserted into this notch 11A. Then, the abutment pieces 11B abut against the outside of the flange R1, and the locking pieces 11C lock onto the inside of the flange R1 (see Fig. 4). As a result, when a load is applied from the locking portion 10 in the direction of the light groove steel R, the pair of abutment pieces 11B support the load.

[0030] On the other hand, locking piece 11C is locked to the inside of flange R1, thereby preventing misalignment of locking portion 10. Furthermore, when a large load is applied to locking piece 11C, the load is also applied to abutting piece 11B via notch 11A, and the entire bent piece 11 is structured to support the load, preventing deformation of abutting piece 11B and notch 11A and providing strong support.

[0031] The abutment body 20 is bent from the engaging portion 10 and is a portion that abuts against the outside of the web R2 of light-gauge steel (see FIG. 4). This abutment body 20 is provided with a long hole 21 through which the fixing screw 40 is inserted, and a pair of abutment pieces 22 that abut against the web R2 (see FIG. 1). The abutment pieces 22 are bent and extended from both longitudinal side edges of the abutment body 20, and form a gap between the web R2 and the abutment body 20 by abutting against the web R2 (see FIG. 4). This gap is used to connect the support member Q to the connection port 2 provided in the abutment body 20 (see FIGS. 5 and 6).

[0032] The connection port 2 is formed in the engaging portion 10 as well as in the contact body 20 (see FIG. 1). A support member Q that supports a supported member P such as an electric conduit is connected to the connection port 2 (see FIGS. 5 and 6). The support member Q shown in FIG. 5 is a support member Q used when supporting a pipe or the like using a cable tie. That is, a cable tie is inserted into an insertion port Q1 formed in the support member Q, and the cable tie is used to support the pipe, cable, or the like.

[0033] 6 shows an example in which a pipe support fitting that directly supports a pipe is used as the support member Q. When such a pipe support fitting is used as the support member Q, the supported member P (electric conduit) is directly supported via the support member Q to the support fitting 1 attached to the light channel steel R (see FIG. 7). In this way, by connecting various types of support members Q to the connection port 2, it becomes possible to support various types of supported members P corresponding to the support member Q.

[0034] The connecting port 2 in the illustrated example has a reinforcing ring 2A formed along the inside of the circular opening edge, which has a thickness that protrudes toward the light channel steel R (see FIG. 2). This reinforcing ring 2A increases the strength of the connecting port 2 and increases the plate thickness of the locking part 10 and the abutting body 20 that form the connecting port 2. As a result, even if a support member Q cannot be connected with the plate thickness of the locking part 10 due to plate thickness restrictions, it can be connected by increasing the plate thickness of the connecting port 2 part with the reinforcing ring 2A. The diameter of the connecting port 2 can be changed arbitrarily depending on the type of support member Q, and it is also possible to form a connecting port 2 with a small diameter when using a bolt or the like as the support member Q, in addition to the illustrated example.

[0035] The crimping and fixing part 30 is a part provided at the end of the contact body 20 so as to be able to swing (see FIG. 4). Furthermore, a fixing screw 40 is inserted into an elongated hole 21 formed at the end side of the contact body 20, and this fixing screw 40 is screwed to the crimping and fixing part 30. When the fixing screw 40 is tightened, the crimping and fixing part 30 swings, and the crimping and fixing part 30 is crimped and fixed to the end of the other flange R1 of the flange R1.

[0036] The illustrated crimping and fixing part 30 includes a bending part 31, a fixing part 32, and a swinging part 33 (see FIG. 2). The bending part 31 is a part that is extended from an end part of the contact body 20 so as to be freely bent. The fixing part 32 is extended from the bending part 31 and has a screw hole 34 for screwing the fixing screw 40. The swinging part 33 is provided with a crimping part 35 that is extended from the fixing part 32 and is crimped to the other flange R1. The swinging part 33 is a part that moves together with the fixing part 32 in the direction of the flange R1 by tightening the fixing screw 40. The swinging part 33 shown in FIG. 4 is formed so as to form a substantially right angle with the fixing part 32.

[0037] 8, the swinging portion 33 may be formed at an angle from the fixed portion 32 (second embodiment). In other words, it is sufficient that the swinging portion 33 and the fixed portion 32 move together regardless of the angle.

[0038] The procedure for attaching the support bracket 1 of the present invention will be described with reference to Figures 3 and 4. The worker holds the support bracket 1 and inserts the tip of one flange R1 of the light channel steel R into the notch 11A of the locking part 10 (see Figure 3). At this time, the fixing part 32 is screwed into the fixing screw 40 with the crimping part 35 of the crimping fixing part 30 open so as not to touch the other flange R1.

[0039] Next, the abutment piece 22 of the abutment body 20 is abutted against the web R2 of the light channel steel R, and the fixing screw 40 is tightened (see FIG. 4). Then, the oscillating portion 33 of the crimping fixing portion 30 gradually approaches the abutment body 20, and the crimping portion 35 is crimped against the other flange R1. When the crimping portion 35 is crimped against the flange R1 in this manner, the attachment is complete. Therefore, the work of attaching the support bracket 1 to the light channel steel R is an extremely simple task of merely engaging the engaging portion 10 with the flange R1 of the light channel steel R, and tightening the fixing screw 40.

[0040] The fixing screw 40 is inserted through the elongated hole 21 of the contact body 20. Therefore, when the fixing screw 40 is tightened, the crimping fixing part 30 gradually moves along the elongated hole 21 (see FIG. 4). The illustrated fixing screw 40 is a tapping screw, so that the screw hole 34 formed in the crimping fixing part 30 can be tightened even if it is a hole that is simply opened with a drill or the like. This fixing screw 40 may be attached later. It is also possible to use a metric screw for the fixing screw 40.

[0041] 9 to 12 show a third and fourth embodiment of the present invention. In both of these embodiments, the crimping and fixing part 30 is swung by a pressing means instead of the fixing screw 40. The pressing means includes bending by hand and fastening with a bolt or the like. The configurations other than the crimping and fixing part 30, such as the configurations of the locking part 10 and the contact body 20, are the same as those of the previous embodiments.

[0042] The crimping and fixing part 30 of the third embodiment shown in Figures 9 and 10 has almost the same configuration as the crimping and fixing part 30 of the previous embodiment, but in particular, the bending part 31 is of a minimum size, there is no screw hole 34, and instead has a locking claw 36 (see Figure 9). When the crimping and fixing part 30 is bent by placing a hand on the swinging part 33 and the crimping part 35 is swung to the crimping position of the flange R1, the locking claw 36 locks with the back surface of the abutment body 20, and the crimping and fixing part 30 is fixed (see Figure 10). The illustrated locking claw 36 is provided on one side edge of the fixing part 32, but the locking claw 36 may be provided on both sides of the fixing part 32.

[0043] The crimping and fixing part 30 of the fourth embodiment shown in Figs. 11 and 12 has the same configuration as the crimping and fixing part 30 of the third embodiment, and includes the locking claw 36. The difference in the configuration is that the crimping and fixing part 30 is provided with a bending part 31 (see Fig. 11). Therefore, when the crimping and fixing part 30 is bent by placing a finger on the swinging part 33 and the crimping part 35 is swung to the crimping position of the flange R1, the locking claw 36 locks with the abutment body 20 in a state where a gap is generated between the fixing part 32 and the abutment body 20, and the crimping and fixing part 30 is fixed (see Fig. 11). The locking claw 36 shown in the figure is provided on one side edge of the crimping and fixing part 30, but it may be provided on both sides, and it is also possible to configure it so that it is locked from the center part of the crimping and fixing part 30 to the long hole 21 provided in the abutment body 20.

[0044] The contact body 20 shown in the figures is provided with a connection port 2 for connecting the support member Q (see Figs. 9 to 12). It is also possible to provide the contact body 20 with a shape that is bent in a generally V-shape on the outer side of the web R2, and provide a plurality of connection ports 2 on this bent surface (not shown).

[0045] In the embodiment, the example is shown as being attached to a light-weight groove steel R as a lightweight shaped steel, but it is also possible to attach it to a lip groove steel. It is also possible to attach it to an H-shaped steel or an angle steel. In this way, the embodiments of the present invention are not limited to the illustrated examples, and non-lightweight shaped steel is also possible, and design changes are free to the extent that they do not change the gist of the present invention.
