To achieve the above object, the holder for hanging bolts for ceilings, etc. of the present invention has the following features: (1) Projects from below between the opposing walls of the receiving groove of the mounting member and rotates approximately at right angles to engage in the receiving groove. A hanging nut with a flange on the top and a pair of locking protrusions projecting laterally on the bottom; a locking plate having a pair of upright pieces that regulates the locking plate; ■ a coil spring disposed on the lower surface of the locking plate to bias the locking plate upward; and ■ an engagement recess that snaps into the locking protrusion. is provided on the inner circumferential side of the upright one wall, and an annular handle body with an annular groove formed on the outer circumferential side of the upright one wall into which the lower end of the coil spring fits, and a breakable bottom surface. A protective cap is provided with a gate piece and is integrally attached to the lower surface side of the handle body. Further, the protective cap may be colored differently depending on the object to be hung and held.

[For production]

The hanging bolt receiver of the present invention has a hanging nut and a handle body with a protective cap configured separately, and after the locking plate and the coil spring are inserted into the hanging nut, the coil spring is held in a compressed state. Push the locking protrusion of the suspension nut into the engagement recess of the handle body, use the elasticity of the upright wall to snap it into place, and then release the compressed state of the coil spring to release the lower end of the coil spring. It is assembled and put into use by fitting it into the annular groove of the handle body. On this occasion,
The coil spring that fits into the annular groove on the outer peripheral surface of the upright wall restricts the elasticity of the upright wall, so the locking protrusion is irremovably fitted into the engagement recess, so that the hanging nut and It is firmly and irremovably connected to the handle body with a protective cap.

In addition, the protective cap that is integrally attached to the bottom of the handle body prevents the condensation prevention material from getting stuck inside the hanging nut even when sprayed with dew condensation prevention material. There is no fear, and even when attaching the hanging bolt to the hanging nut, the gate piece can be pushed through and the hanging bolt can be easily screwed into the hanging nut.

Furthermore, if the protective cap is colored differently depending on the type of object to be hung, such as the ceiling, hanging rack for electrical wiring, air conditioning piping, water piping, fire prevention piping, etc., you can color the protective cap differently. You can quickly and easily hang and hold the corresponding object using the mark.
