Description

  The present invention relates to a mounting bracket for a piping bracket that supports piping in which cables and the like are laid.

  In general, laying of piping lines, such as electrical wiring work indoors and outdoors in houses, buildings, factories, and the like, is performed through wire cables in previously laid piping materials when interior work is completed. In addition, a communication cable piping line made of a metal cable, an optical cable, or the like used for a LAN (Local Area Network) or a WAN (Wide Area Network) is performed through a communication line in a piping material laid in advance.

  Conventionally, a piping bracket for attaching the piping material to a wall surface has been proposed (see Patent Documents 1 to 4).

Japanese Utility Model Publication No. 3-63017 (FIGS. 1 and 2) Japanese Utility Model Publication No. 3-63018 (Figs. 1 and 2) Japanese Utility Model Publication No. 3-63019 (FIGS. 1 and 2) Japanese Utility Model Publication No. 4-86041 (Figs. 1 and 2)

Here, the bracket for piping is used as follows.
A plurality of brackets 100 shown in FIG. 8A are fixed to substantially the same level of the wall surface, and the cable rack 101 is mounted on the plurality of brackets 100 and fixed. Further, a piping material constituting a piping line is placed and fixed on the cable rack 101, and a power line or a communication line is passed through the piping material. Further, the piping material may be directly fixed on the bracket 100.

  The conventional bracket 100 is composed of a single plate whose side surface is formed in a substantially triangular shape. Therefore, many brackets with different lengths of the sides protruding in the horizontal direction from the wall surface are prepared according to the width of the cable rack and the like. Since the bracket is used in a large amount, a remainder often occurs after the completion of construction.

  Therefore, it is possible to divert the surplus brackets to other sites. However, since it is necessary to select a bracket having a desired size from among a large variety of brackets for surplus, it is very complicated and is not generally performed. For this reason, it is difficult to reuse the extra bracket.

On the other hand, when there are obstacles such as wall irregularities or existing pipes, it is necessary to shift the mounting level of the bracket in the vertical direction in order to avoid the obstacles, which makes the finish unsightly.
Therefore, as shown in FIG. 8B, it is conceivable to use a rod-shaped beam 105 and a stay 106 in order to avoid the obstacle. That is, it is conceivable that the beam 105 is mounted so as to protrude in the horizontal direction, and a stay 106 that reinforces the beam 105 is mounted obliquely so that an obstacle is sandwiched between the beam 105 and the stay 106.
The stay 106 supports the beam 105 by a wall-side fastening fitting 107 that fastens the stay 106 and the wall surface 6 and a protruding-side fastening fitting 108 that fastens the beam 105 and the stay 106.

  However, since the length of the stay 106 and the mounting angle of the stay 106 change according to the size of the cable rack 101, the size of the obstacle, and the like, it is necessary to prepare the fasteners 107 and 108 at various angles. In addition, it is necessary to select the fasteners 107 and 108 that match the mounting angle of the stay 106, which makes the mounting operation extremely complicated and impractical.

  Accordingly, a main object of the present invention is to provide a mounting bracket for a piping bracket that can reduce the construction cost and has high workability.

  In order to achieve the above object, the mounting bracket for a piping bracket of the present invention is a mounting bracket for mounting a bracket that is fixed to a predetermined wall surface and supports the piping, and has a length that protrudes horizontally from the wall surface. A fixing bracket that supports an end portion of the wall surface of the long beam, a first hinge member that rotatably supports an end portion of the long stay protruding obliquely upward from the wall surface, and the beam And a second hinge fitting that rotatably couples the ends on the protruding side opposite to the wall-side end of the stay, the first hinge fitting at a position directly below the fixing bracket. A vertical lower plate portion fixed to the wall surface, and a first oblique plate portion that is rotatable with respect to the vertical lower plate portion via a first pin and fixed to an end portion on the wall surface side of the stay, The second hinge bracket is the end of the beam on the protruding side It includes a movable horizontal plate portion, and said to movable horizontal plate portion second oblique plate portion fixed to an end portion of the protruding side of the rotatable said stay via a second pin secured to.

According to the present invention, even when the dimensions of the beam and the stay are different, the angle between the stay and the wall and the stay and the beam can be freely changed by the first and second hinge fittings. The size of the bracket can be created at the work site.
In addition, it is convenient because there is no need to assemble a bracket that can change the mounting angle of the stay on site.
Further, the beam and stay can be manufactured by cutting a general-purpose hanger rail that is generally used at the work site.

  Moreover, since the bracket mounting bracket can correspond to various angles, even if the mounting bracket is left, it can be diverted to other sites. Also, the hanger rail is highly versatile and can be used for other sites. Therefore, unlike the conventional example, a situation in which brackets having different sizes do not occur does not occur, and the cost can be significantly reduced.

Furthermore, even when there are obstacles such as wall irregularities and existing cables, it is necessary to change the mounting level of this mounting bracket by placing the obstacle so that it is sandwiched between the beam and the stay. It is convenient because the piping material can be attached to the stay.
In addition to the vertical wall surface, the bracket can be attached to a slope.
