Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is mainly used for building materials such as equilateral angles (equal angle steel) when there is no dimensional allowance on the top surface of building materials such as equilateral angles in building structures. The present invention relates to a hanging bolt support fitting suitable for supporting hanging bolts of cable racks, lighting equipment, and wiring parts.

(Prior Art) Conventionally, when there is no dimensional clearance on the upper surface of the building material such as an equilateral angle, as shown in FIG. Is engaged with the side U-shaped engaging plate 32, and the side of the hanging bolt support metal fitting 33 is clamped to the lower side of the vertical piece C, and the metal body 34 having a substantially U-shape facing upward is sandwiched from below to form the auxiliary metal fitting. It was supported by being tightened by the support screw 36 together with the screw plate 35 in the lower part of 31.

(Problems to be solved by the invention) However, when supporting a hanging bolt D such as a cable rack, a lighting fixture, and a wiring component on the construction material A such as an equilateral angle, the lower side 37 of the engaging plate 32 of the auxiliary metal fitting 31 and Since the length of the side edge 38 cannot be adjusted in the longitudinal direction, the hooking plate 3 of the auxiliary metal fitting 31 is supported in accordance with various sizes in the width direction of the horizontal piece B and the vertical piece C of the building material A such as an equilateral angle for supporting.
Since the sizes of the lower side 37 and the side 38 of the second side in the longitudinal direction have to be changed, the hanging plate 32 is made to correspond to various sizes in the width direction of the horizontal piece B and the vertical piece C of the building material A such as an equilateral angle. It was necessary to prepare some auxiliary metal fittings 31 having different longitudinal sizes of the lower piece 37 and the side edge 38.

Therefore, the present invention was devised in order to solve the above-mentioned problems, and when supporting hanging bolts such as cable racks, lighting fixtures, wiring parts, etc. on construction materials such as equilateral angles, As shown in Fig. 6, some auxiliary metal fittings with different sizes in the longitudinal direction of the lower piece and side piece of the hanging plate are prepared to correspond to various sizes in the width direction of the horizontal piece and the vertical piece of construction material such as equilateral angles. (EN) Provided is a hanging bolt support fitting that can be used for various sizes in the width direction of a horizontal piece and a vertical piece of a construction material such as an equilateral angle without placing.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention fits an L bolt that is fitted on the outer side of a construction material such as an equilateral angle and a fitting from the inside of a construction material such as an equilateral angle. It is composed of a metal fitting main body that supports both ends of the L bolt together and a suspension support for supporting a hanging bolt that is connected to the center of the metal fitting main body. Long holes are provided at both ends of the metal fitting body, and each threaded portion of the L bolt is movably supported by a nut in each long hole of the metal fitting body.

(Operation) The present invention, when the suspension bolts such as cable racks, lighting fixtures, wiring parts, etc. are supported on the construction material such as the equilateral angle by the above-mentioned technical means, the construction material such as the equilateral angle can be leveled horizontally. The metal fitting body can be moved within the range of each long hole in correspondence with various sizes of the strip and the vertical strip in the width direction.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the hanging bolt support metal fitting of the present invention is fitted from the inside of the building material A such as an L-bolt 1 which is fitted to the outside of the building material A such as an equilateral angle and the like. A metal fitting body 2 which is supported by both ends of the L bolt 1
And a hanging bolt D that is connected to the central portion side of the metal fitting body 2.
It is composed of a suspension support 3 for support.

The L bolt 1 is formed in an L shape from a horizontal portion 5 having a threaded portion 4 at a tip portion and a vertical portion 7 having a threaded portion 6 at a lower end portion.

Further, in the metal fitting body 2, a vertical plate 10 having a long hole 9 formed at the center is bent at the upper end of the swash plate 8, and at the lower end of the swash plate 8, a long hole 11 is formed at the center. A horizontal plate 12 having a plurality of holes is formed by folding, and at both side edges of the swash plate 8, two side plates 14 having two connecting holes 13 at the center in the width direction are formed at appropriate intervals in the longitudinal direction. The vertical plate 10 and the horizontal plate 12 are bent on the same bending side, and the side edges of each side plate 14 are provided with notches 15 for escape of the horizontal side B and the vertical side C of the construction material A, respectively. Has been formed.

Further, the suspension support 3 has a bottom plate 17 having a support hole 16 for the suspension bolt D at the center thereof and a connecting hole 18 at the upper end thereof.
Is formed into a substantially U-shape on the front surface from the side plates 19 respectively bored.

The threaded portion 4 of the horizontal portion 5 of the L bolt 1 is movably inserted into the long hole 9 of the vertical plate 10 of the metal fitting body 2 formed as described above, and the long hole of the horizontal plate 12 of the metal fitting body 2 is inserted. 1
The screw portion 6 of the vertical portion 7 of the L bolt 1 is movably inserted into the nut 1 to be supported by the nuts 20 and 21, respectively.
3, the connection holes 18 of both side plates 19 of the suspension support 3 are connected via connection bolts 22 and nuts 23.

(Effect of the Invention) Since the present invention is configured as described above, the L bolt 1 is fitted to the outside of the construction material A such as an equilateral angle when used, as shown in FIGS. 3 and 4. Also, by fitting from inside the construction material A such as an equilateral angle, the threaded portions 4 and 6 at both ends of the L bolt 1 are movably inserted into the elongated holes 9 and 11 at both ends of the metal fitting body 2. When the suspension bolts D such as cable racks, lighting fixtures, wiring parts, etc. are supported on the construction material A such as an equilateral angle by supporting the nuts 20 and 21, respectively, the construction material A such as an equilateral angle is horizontal. Since the metal fitting body 2 can be moved within the range of the elongated holes 9 and 11 in correspondence with various sizes of the strip B and the vertical strip C in the width direction, the lower strip 37 and the side 38 of the engaging plate 32 as in the conventional case. Please prepare some auxiliary metal fittings 31 with different sizes in the longitudinal direction. Instead, it can be used for various sizes in the width direction of the horizontal side B and the vertical side C of the construction material A such as an equilateral angle.
