A mounting bracket composed of a holding member for holding a mounting member such as a pipe and a fastening bolt has been known for a long time.

In the conventional mounting bracket as described above, the holding member composed of two members, a receiving member and a holding member, is connected to each other with a fastening bolt at the site with a mounting member such as a pipe sandwiched between them. Yes, for example, in a state where a mounting member such as a pipe is sandwiched between a receiving member and a holding member, this holding member cannot be temporarily fixed to the U-shaped clamp, and the mounting member is always temporarily received with a hand. There is a problem that the workability is poor and it is difficult to work efficiently because the work must be maintained.

The present invention proposes a mounting bracket such as a pipe that can solve the above-mentioned conventional problems, and the mounting bracket such as a pipe according to the present invention has a relationship with an embodiment described later. For the sake of clarity, the reference numerals used in the description of the embodiment are shown in parentheses, and are provided with a U-shaped continuous recessed space (4) inside and on the mounting plate (5). It consists of a U-shaped clamp (1) that is fitted and fixed with a fixing bolt (6), a holding tool (2) that holds a mounting member (14) such as a pipe, and a fastening bolt (3). In 1), there is a sub-plate part (8) facing the main plate part (7) through which the fixing bolt (6) is screwed through, and a connecting plate part (8) that connects these main plate parts (7) and the sub-plate part (8). A connecting hole (11) is provided in at least one of the plates of 9), and the holding tool (2) mainly includes a holding portion (15, 16) for holding the mounting member (14). It is composed of two sub-pinching members (12,13), and the tip of these main-sub-pinching members (12,13) in front of the pinching portion (15,16) projects outwardly away from each other. Locking pieces (18, 19) to be inserted into the connecting hole (11) are provided, and the sub-pinching member (13) has an overhanging portion (24) for preventing slippage at the end behind the pinching portion (16). The main sandwiching member (12) is provided with a bendable extension plate portion (22) that extends from the end rearward of the sandwiching portion (15) to the side of the sub-pinching member (13). An engaging hole (23) through which a portion of the sub-pinching member (13) adjacent to the retaining overhanging portion (24) penetrates through the extending plate portion (22) is formed in the extending plate portion (22). It is provided in a long hole shape along the extending direction, and is provided between the holding portion (15) of the main holding member (12) and the extending plate portion (22), and the holding portion (13) of the sub holding member (13). One of the spaces between the 16) and the retaining portion (24) is provided with a long hole (20) long in the length direction of the holding member (12, 13), and the other is penetrated. A screw hole (21) is provided, and the fastening bolt (3) is configured such that the tip side penetrating the elongated hole (20) screw-penetrates the penetrating screw hole (21).

In the above configuration, the holding tool composed of two main and sub holding members is integrated by the fastening bolt whose tip end side penetrating the elongated hole of one holding member screwed through the through screw hole of the other holding member. Moreover, the portion of the sub-pinching member adjacent to the retaining overhang portion penetrates the engagement hole of the extension plate portion of the main pinching member, so that the two main and sub-pinching members have the fastening bolt. It is in a state where it cannot rotate relative to the circumference of. If the fastening bolt is twisted back within a range that does not come off from the through screw hole in this state, there are a long hole through which the fastening bolt penetrates and a long hole-shaped engaging hole in the extension plate portion. Can be used to relatively open the two main and sub-holding members so that the locking pieces at the tips thereof are separated from each other. By widening the distance between the tips of the two main and sub holding members in this way, the mounting member (piping, etc.) can be relatively inserted between the holding portions from the tip side of both holding members. Of course, when the spread between the tips of the two main and sub holding members is small, the mounting member can be inserted from the side between the holding portions of both holding members.

After that, by sandwiching the tip ends of the two main and sub-holding members with fingertips and bringing the locking pieces at the tips of both holding members close to each other, the locking pieces at the tips of both holding members can be attached to the mounting member (piping, etc.). ) Can be inserted into the connecting hole of the U-shaped clamp previously attached to the structural steel or the like to which it should be attached. From this state, hold the rear end side of both holding members with your fingertips, spread the tip side of both holding members using the mounting member (piping, etc.) sandwiched by both holding members as a fulcrum, and lock the tips of both holding members. When the piece is inserted into the back side of the connecting hole of the U-shaped clamp, the extension plate portion of the main clamp member is rearward with the inside of the overhanging portion for preventing the rear end of the sub-pinching member as a bent position.

As a result, the postures of both holding members are fixed to the mounting member (piping, etc.), the holding tool holding the mounting member (pipe, etc.) is temporarily fixed to the U-shaped clamp, and the hand is temporarily fixed to the U-shaped clamp. Can be separated.

If the holding tool that holds the mounting member (pipe, etc.) is temporarily fixed to the U-shaped clamp as described above, the mounting member (pipe, etc.) is fixed to the clamp after correcting the position in the length direction. A bolt is screwed in to forcibly move the rear end sides of both holding members extending rearward from the mounting member (pipe, etc.) closer to each other and enter the back side of the connecting hole of the U-shaped clamp. By forcibly opening the tip end side of both holding members provided with the locking pieces and pressing them against the inner peripheral surface of the connecting hole, the holding tool that holds the mounting member (pipe, etc.) at a predetermined position is said. Can be completely fixed to the U-shaped clamp. The extension plate portion of the main holding member bent outward for temporary fixing may be left as it is, but if it gets in the way, it may be returned to its original posture. When it becomes necessary to remove the attached mounting member (piping, etc.), if the extension plate portion is in a bent state, twist the fastening bolt with the extension plate portion returned to its original posture. In a state where the fastening of the rear end side of both holding members is released, the tip end side of both holding members is sandwiched between the fingertips, and both locking pieces are moved close to each other, the locking of the tip side of both holding members is performed. The piece may be pulled out from the connecting hole of the U-shaped clamp, and the holding tool may be removed from the U-shaped clamp.

As described above, according to the mounting bracket for piping and the like of the present invention, not only the two main and sub holding members constituting the holding tool are integrated by the fastening bolts, but also both holding members are around the fastening bolts. Since it does not rotate relative to each other, the operation of connecting to the U-shaped clamp can be performed easily and efficiently. Moreover, when the mounting member (piping, etc.) is sandwiched between the sandwiching parts of the two main and sub sandwiching members, the space between the two sandwiching members can be greatly widened, so that the mounting member (piping, etc.) can be placed from the side with respect to the sandwiching tool. In addition to inserting it, it is also possible to fit the middle part of the mounting member (such as piping) into the holding tool. Then, before screwing in the fastening bolt, it is possible to easily connect the holding tool in the state of holding the mounting member (pipe, etc.) to the U-shaped clamp and temporarily fix it, so that workability is significantly improved. After correcting the mounting position of the mounting member (piping, etc.) in the temporarily fixed state, the mounting member (piping, etc.) can be securely fixed to the U-shaped clamp simply by screwing in the fastening bolt.

The elongated hole (20) is provided in the main sandwiching member (12), and the through screw hole (21) is provided in the sub-pinching member (13), whereby the elongated hole (12) is provided in the main sandwiching member (12). Since the protruding direction of the fastening bolt (3) from 20) on the head side and the extending direction of the extending plate portion (22) provided on the main holding member (12) are opposite to each other, both of them are mutually exclusive. There is no risk of interference, and the extension plate portion can be easily configured.

Further, the connecting hole (11) of the U-shaped clamp (1) is circular, and the holding portion (15, 16) of the two main and sub holding members (12, 13) is connected to the locking piece (18, 19). The portion of can be formed into an arc-shaped cross section that fits in the circular connecting hole (11) so as to be relatively rotatable. According to this configuration, the holding tool is rotated with respect to the connecting hole of the U-shaped clamp while increasing the strength on the tip side of both holding members, and the angle of the mounting member (pipe, etc.) held by the holding member is adjusted. It can be adjusted. Further, in addition to this configuration, the holding portion (15, 16) of the two main and sub holding members (12, 13) has an arc shape that protrudes outward, and the holding portion (15) having an arc shape.
