Description

Article 30, paragraph 2 of the Patent Act is applicable. Published in the "Notice of the end of sales of the light channel steel conduit support bracket "T38"" of the Negros Electric Co., Ltd. product catalog issued on December 1, 2020.

The present invention relates to a support for shaped steel that is attached to light-gauge shaped steel used as a base material for furring strips, purlins, etc., and is used primarily to support electrical wires, piping, etc.

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

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.

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 supports the electric conduit by placing it on the upper surface of the lip channel steel with the opening facing downward, and is configured to be fixed to the lip edge of the lip channel steel.

On the other hand, the support bracket 100 shown in FIG. 13 is used as a bracket for supporting electric conduits on light-gauge steel. This support bracket 100 is a bracket for supporting electric conduits on light-gauge steel R (light-gauge steel) used as a siding support material. This support bracket 100 is composed of a gripping member 110 and a connecting and locking portion 120.

The gripping member 110 has an abutment portion 111 that abuts against the web R2 of the light channel steel R, and an engagement portion 112 that is pre-engaged with one of the flanges 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 web R2 attached)

The connecting and locking portion 120 is a separate member from the gripping member 110, and is a member that locks to the other flange R1 of the light channel steel R. This connecting and locking portion 120 is provided with a locking portion 121 with a generally 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 portion 120 is screwed to the gripping member 110 side with the connecting bolt 200 inserted into the bolt hole 113 of the gripping member 110, thereby locking the locking portion 121 of the connecting and locking portion 120 to the flange R1.

Japanese Utility Model Application Publication No. 5-27480 Patent No. 3874700

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 electrical conduits, etc., on light channel steel that does not have a lip.

On the other hand, the conventional support fitting shown in FIG. 13 is configured to support electric conduits or the like on a light channel steel R without a lip. However, there was a problem in that the work of attaching this support fitting to the light channel 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 it to the lower end of the gripping member 110 with a connecting bolt 200. 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 installation operations required a lot of work.

Moreover, the locking portion 112 formed on the gripping member 110 is formed by bending the tip of the gripping member 110. Therefore, when a large load is applied to the locking portion 112, the bent portion of the locking portion 112 tends to gradually open, and there is a risk that the support strength will decrease.

The present invention was created to solve the problems of the past, and aims to provide a support for lightweight shaped steel that is extremely easy to attach to the steel and has excellent support strength.

The first means of the present invention to achieve the above-mentioned object is a support 1 attached to the outside of a shaped steel, which is provided with an engaging portion 10 that engages with one flange R1 of the shaped steel, an abutment body 20 that abuts from the engaging portion 10 to the outside of the web R2 of the shaped steel, and a crimping and fixing portion 30 that is provided at the end of the abutment body 20 so as to be able to swing 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 the crimping and fixing portion 30 can swing to the crimping position of the flange R1 when the fixing screw 40 is tightened.

The second means is a support 1 that is attached to a shaped steel and includes a contact body 20 that contacts one end of the width of one flange R1 of the shaped steel, and a crimping and fixing part 30 that is pivotally attached to the contact body 20 and can be engaged with the other end of the width of the flange R1.

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

The abutment body 20 of the fourth means is equipped with an abutment piece 22 that abuts against the outside of the steel section on one end side of the width portion of the flange R1.

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

The crimping and fixing portion 30 of the sixth means has a bending portion 31 that is freely bent and extended from the end of the abutment body 20, a fixing portion 32 that is bent and extended from the bending portion 31, and a swinging portion 33 that is bent and extended from the fixing portion 32 and has a crimping portion 35 that is crimped to the other flange R1.

The abutment body 20 of the seventh means has a long hole 21, the fixing portion 32 has a screw hole 34, and a fixing screw 40 for screwing the crimping fixing portion to the abutment body is inserted into the long hole 21 and screwed into the screw hole 34.

The abutment body 20 of the eighth means is formed by bending the engaging portion 10 .

The ninth means includes a locking portion 10 that locks onto one flange R1 of the shaped steel.

The tenth means includes a locking claw for fixing the crimping and fixing part 30 to the abutment body 20 when the crimping and fixing part 30 is swung to the crimping position of the flange R1.

In the eleventh means, a support device attached to the outside of a structural steel having two flange R1 ends comprises a bent piece 11 with a notch 11A that hooks onto and engages with one of the flange R1 ends of the structural steel, an abutment body 20 that abuts against the web R2 of the structural steel, and a crimped and fixed part 30 that can be engaged with the other flange R1 end of the structural steel.After the bent piece 11 is engaged with one of the flange R1 ends of the structural steel, when a fixing screw 40 provided on the support device is tightened, the crimped and fixed part 30 is crimped onto the other flange R1 end of the structural steel, and the structural steel is attached to the structural steel.

According to the present invention, the support fitting of the present invention can be attached to the flange of lightweight steel very easily. Moreover, the strength of the part that engages with the flange and the support strength of the part that connects the support member that supports the electric conduit, etc. can be increased.

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

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

That is, the locking portion 10 is a portion that locks to one of the flanges R1 of the light channel steel R (see FIG. 4). This locking portion 10 has a pair of bent pieces 11 that are bent from the left and right side edges of 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 of the flanges R1 is inserted (see FIG. 2). In addition, the bent pieces 11 are provided with an abutment piece 11B that abuts against the top surface of the flange R1 via this notch 11A, and a locking piece 11C that locks to the inside of the flange R1.

As shown in Figure 3, one flange R1 of the light groove steel R is inserted into this notch 11A. Then, the abutment piece 11B abuts against the outside of this flange R1, and the locking piece 11C locks into the inside of the flange R1 (see Figure 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.

On the other hand, the locking piece 11C prevents the locking part 10 from shifting position by locking to the inside of the flange R1. In addition, when a large load is applied to the locking piece 11C, the load is also applied to the abutting piece 11B via the notch 11A, and the entire bent piece 11 is structured to support the load, preventing deformation of the abutting piece 11B and notch 11A and providing strong support.

The abutment body 20 is bent from the engaging portion 10 and abuts against the outside of the web R2 of the light-gauge steel (see FIG. 4). This abutment body 20 has 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 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 on the abutment body 20 (see FIG. 5 and FIG. 6).

The connection port 2 is formed not only in the contact body 20 but also in the locking portion 10 (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 piping, etc., 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 piping, cables, etc.

The support member Q shown in Figure 6 shows an example in which a pipe support fitting that directly supports the 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 (electrical conduit) is directly supported via the support member Q to the support fitting 1 attached to the light channel steel R (see Figure 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.

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 groove 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 abutment 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. In addition, the diameter of the connecting port 2 can be changed arbitrarily depending on the type of support member Q, and in addition to the illustrated example, 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.

The crimping and fixing part 30 is a part that is provided at the end of the abutment body 20 so that it can swing freely (see FIG. 4). Furthermore, a fixing screw 40 is inserted into a long hole 21 formed at the end side of the abutment 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 other end of the flange R1.

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 the end of the abutment body 20 in a freely bending manner. The fixing part 32 is extended from the bending part 31 and forms 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 an approximately right angle with the fixing part 32.

Also, as shown in FIG. 8, the oscillating part 33 may be formed at an angle from the fixed part 32 (second embodiment). In other words, it is sufficient that the oscillating part 33 and the fixed part 32 are configured to move together regardless of the angle.

The procedure for installing the support bracket 1 of the present invention is explained 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 portion 10 (see Figure 3). At this time, the fixing portion 32 is screwed into the fixing screw 40 with the crimping portion 35 of the crimping fixing portion 30 open enough not to touch the other flange R1.

Next, the abutment piece 22 of the abutment body 20 is abutted against the web R2 of the light groove steel R, and the fixing screw 40 is tightened (see Figure 4). Then, the oscillating part 33 of the crimping fixing part 30 gradually approaches the abutment body 20, and the crimping part 35 is crimped against the other flange R1. When the crimping part 35 is crimped against the flange R1 in this way, the installation is complete. Therefore, the work of installing the support bracket 1 to the light groove steel R is an extremely simple task of simply engaging the engaging part 10 with the flange R1 of the light groove steel R and tightening the fixing screw 40.

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

Figures 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 oscillated by a pressing means instead of a fixing screw 40. The pressing means includes bending by hand and fastening with a bolt or the like. The configuration other than the crimping and fixing part 30, such as the configuration of the locking part 10 and the contact body 20, is the same as the previous embodiments.

The crimping and fixing part 30 of the third embodiment shown in Figures 9 and 10 has a configuration similar to that of 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 onto the back surface of the abutment body 20, and the crimping and fixing part 30 is fixed (see Figure 10). The locking claw 36 shown 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.

The crimping and fixing part 30 of the fourth embodiment shown in Figures 11 and 12 has the same configuration as the crimping and fixing part 30 of the third embodiment, and is equipped with a locking claw 36. The difference in the configuration is that the crimping and fixing part 30 is provided with a bending part 31 (see Figure 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 with a gap between the fixing part 32 and the abutment body 20, and the crimping and fixing part 30 is fixed (see Figure 11). The locking claw 36 shown 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 locks from the center part of the crimping and fixing part 30 to the long hole 21 provided in the abutment body 20.

The contact body 20 shown in the figure has 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 roughly V-shape on the side outside the web R2, and provide multiple connection ports 2 on this bent surface (not shown).

In the examples, the light-weight steel is attached to a light-weight groove steel R, but it can also be attached to a lip groove steel. It can also be attached to an H-shaped steel or an angle steel. In this way, the embodiments of the present invention are not limited to the examples shown in the drawings, and non-lightweight steel is also possible, and design changes are free to the extent that they do not change the gist of the present invention.
