BACKGROUND ART Buildings such as restaurants and coffee shops may have sloped ceilings, and special inserts must be used to suspend lighting equipment and other fixtures from the sloped ceiling.

When installing a general insert into a formwork, the contact surface that comes into close contact with the formwork is perpendicular to the axis of the female thread provided inside, but inserts that are buried in a sloped ceiling Both must be sloped according to the slope of the ceiling.

A conventional insert buried in a sloped ceiling has a structure as shown in FIG. 14.

This insert has a seat plate 52 with respect to the main body 51.
The seat plate 52 of the main body 51 is inclined and integrally formed.
For this reason, many types of inserts with different angles of inclination of the seat plate 51 are manufactured and prepared, and the one corresponding to the angle of inclination of the ceiling to be buried is selected and used.

Inserts with such a structure require the manufacture and preparation of many types of inserts with different angles of inclination relative to the main body 51, which increases manufacturing costs and makes it difficult to store and manage the various types of inserts. Become.

[Problem to be solved by the invention]

An object of the present invention is to make it possible to vertically hang a hanging rod on a sloped ceiling having a wide range of slope angles using one type of insert.

[Means to solve the problem]

The insert according to the present invention includes a slider in which an arcuate slide body is provided at the lower end of a hollow main body, and a female threaded part is provided on the inner circumferential surface of the main body to be screwed into a hanging rod; It consists of a pedestal having a slide guide surface on its upper surface that corresponds to the slide body of the slider, and the inclination of the slider can be adjusted by sliding the slide body along the slide guide surface of the pedestal. It is characterized by being configured so that it can be fixed to formwork.

[Operation of the Invention] First, the pedestal is fixed to a predetermined position of the inclined formwork via a fixing means.

The pedestal and the slider are connected to each other so that the sliding body of the slider can slide along the slide guide surface of the pedestal, and the vertical cross-sectional shape of the slide guide surface provided on the pedestal is arc-shaped. Therefore, the slider slides in the circumferential direction.

The slider is slid relative to the pedestal until the axis of the female screw portion provided on the slider becomes vertical, and in this state the slider is fixed to the formwork via the fixing means.

Now, the axis of the female thread provided on the slider is vertical, and the pedestal and slider are
Each is fixed to the formwork via fixing means. After concrete is poured, the formwork is removed and the male threaded portion at the tip of the hanging rod is screwed together with the female threaded portion of the slider, so that the hanging rod is suspended vertically from the insert buried in the concrete.

In this way, by sliding the slider in the circumferential direction, the position of the slider relative to the pedestal can be freely changed and both can be fixed to the formwork. can always be vertical, and one type of insert makes it possible to hang the hanging rod vertically on sloped ceilings of various angles of inclination.

Also, unlike the method of fixing the insert to the inclined formwork described above, it is possible to temporarily hold the pedestal with one hand and adjust the inclination of the slider with the other hand, and then attach both the pedestal and slider to the formwork at the same time. It is possible to fix it.

〔Example〕

An insert according to the invention is shown in FIGS. 1-13.

The insert according to the present invention includes a pedestal A that is directly fixed to the formwork 22, and a slider B that is slidably fitted to the pedestal A via a slide body 13 in the circumferential direction.

As shown in Figures 1 to 3, the pedestal A
The bottom surface of the main body 1 is open and flat, and the top surface thereof is provided with a shallow groove 2, and the bottom surface of the groove 2 serves as a first slide guide surface 3. This first slide guide surface 3
The longitudinal cross-sectional shape of is in the form of a circular arc with a radius R,
In the center thereof, an elongated hole through which a hanging rod 24 (described later) is inserted is provided in the curved direction of the first slide guide surface 3. The opposing inner walls of the shallow groove portion 2 whose bottom surface is the first slide guide surface 3 are in an undercut shape, and this portion serves as a fitting recess into which a slide body 13 of a slider B, which will be described later, is fitted. 5 is formed.

Second slide guide surfaces 6 are provided on both sides of the first slide guide surface 3, respectively. The second slide guide surface 6 is curved in the same direction as the curve direction of the first slide guide surface 3, and is inclined along the width direction so that the inner side is higher than the outer side. A groove 8 is provided in the center of the second slide guide surface 6 in a curved direction to facilitate driving of the nail 7.

The main body 1 of the pedestal A is provided with a fixing body 9 for fixing to the formwork 22. This fixed body 9 has a long hole 10 for inserting the nail 7 and a formwork 22.
A nail extraction hole 11 for extracting the nail 7 from the fixed body 9 after removal is provided continuously.

As shown in FIGS. 1, 4 to 6, the main body 12 of the slider B has a cylindrical shape, and a slide body 13 is integrally provided at the lower end thereof. The vertical cross-sectional shape of the lower surface of this slide body 13 is the same as the vertical cross-sectional shape of the first slide guide surface 3 provided on the pedestal A, and is in the shape of a circular arc with a radius R. Both side end surfaces of the slide body 13 are tapered and form fitting protrusions 14 corresponding to the fitting recesses 5 of the pedestal A.

A pair of fixing bodies 15 for fixing the slider B itself to the formwork 22 are integrally provided on the slide body 13 and protrude laterally from both sides of the slide body 13 . When the pedestal A and the slider B are fitted together, the lower surface of the solid body 15 comes into close contact with the second slide guide surface 6 provided on the pedestal A.

Therefore, the fixed body 15 is inclined along the width direction of the slide body 13 so that the upper surface faces outward. The fixed body 15 is provided with a nail hole 16 facing inward (see FIG. 6). The reason why the nail holes 16 are directed inward in this way is to avoid interference with the flange 19 in the post-surgery process and to facilitate the nailing work for fixing the slider B to the formwork 22. .

An anchor body 17 is attached to the main body 12 of the slider B.
This anchor body 17 is provided with a female screw portion 18 and a flange portion 19.

When the fitting protrusions 14 provided on both side end faces of the slide body 13 of the slider B are fitted into the fitting recesses 5 provided in the opposing inner walls of the groove 2 of the pedestal A, as shown in FIG. As shown in FIG. 10, the slide body 13 of the slider B can slide along the first slide guide surface 3 of the pedestal A, and the pedestal A and the slider B are connected to each other.

When sliding the slide body 13 of the slider B along the first slide guide surface 3 of the pedestal A,
The slider B rotates in the circumferential direction of a circle having a radius R and centered on the center C of the arc that is the longitudinal section of the first slide guide surface 3 of the pedestal A. As a result, the female threaded portion 1 provided on the slider B
The position of the axis 21 of 8 changes with respect to the pedestal A.

In order to bury the insert consisting of the pedestal A and the slider B in a sloped ceiling, first insert the fixing body 9 provided in the pedestal A into the elongated hole 10, as shown in FIGS. 10 and 11. Nails 7 are inserted and the pedestal A is temporarily fixed to the inclined formwork 22 using the nails 7. Next, the axis 21 of the female threaded portion 18 provided on the slider B (see Fig. 11)
Slide slider B with respect to pedestal A so that it is perpendicular. Finally, when the nails 7 are inserted and driven into the nail holes 6 of the pair of fixed bodies 15 provided on the slider B, they pass through the grooves 8 provided on the second slide guide surface 6 of the pedestal A and form the formwork. Nail 7 on 22
is entered.

As a result, the pedestal A, which was temporarily fixed to the formwork 22, is fixed, and at the same time, the slider B, which was slidably connected to the pedestal A, is also fixed to the formwork 22. When concrete 23 is poured in this state, the pedestal A and slider B are buried in the concrete 23 as one body.

After pouring the concrete 23, the formwork 22 is removed, and then the nail 7 driven into the fixed body 9 of the pedestal A is moved along the elongated hole 10 to the side of the main body 1 of the pedestal A, and the head of the nail 7 is removed. When the hanging rod 24 is pulled out from the nail extraction hole 11 and the hanging rod 24 is screwed into the female threaded part 18 of the slider B, the hanging rod 24 and the nail 7 should not interfere with each other.

When the male threaded portion 24a of the hanging rod 24 is screwed into the female threaded portion 18 of the slider B through the elongated hole 4 provided in the first slide guide surface 3 of the pedestal A, the first
As shown in FIG. 2, a hanging rod 24 is vertically suspended from an insert consisting of a pedestal A and a slider B.

FIG. 13 shows an insert according to the present invention embedded in a sloped ceiling having a slope angle θ ₂ smaller than the slope angle θ ₁ of the sloped ceiling shown in FIG. 12, and a hanging rod 24 suspended from this insert. It is a sectional view of the state.

In this way, by sliding the slider B in the circumferential direction, the position of the slider B with respect to the pedestal A can be freely changed, and both A and B can be moved into the formwork 2.
2, the axis 21 of the female threaded part 18 provided on the slider B can always be vertical, and with one type of insert, it can be attached to a hanging rod on a sloped ceiling with various slope angles. 24 can be hung vertically.

Since the inclination angle of the inclined ceiling surface is often a specific angle, the fitting recess 5 of the pedestal A and the slider B
A small protrusion and a recess into which the small protrusion is fitted are provided at predetermined positions on each part of the fitting protrusion 14 in the curved direction of the first slide guide surface 3, and the slider B is slid. At this time, by lightly fitting the small protrusion and the recess, the axis 21 of the female thread 18 provided on the slider B can be easily made vertical. Further, if scales are provided on the pedestal A and the slider B, the inclination of the slider B can be easily adjusted.

Note that the connection structure between the pedestal and the slider is not limited to the above-described fitting structure, and the pedestal and the slider do not necessarily have to be connected.

〔Effect of the invention〕

In the insert according to the present invention, the slider provided with the female threaded portion that is screwed into the hanging rod is configured to be slidable in the circumferential direction, so that the axis of the female threaded portion provided on the slider is always kept vertical. Can be fixed to formwork.

Therefore, by using one type of insert, the hanging rod can be vertically hung on a sloped ceiling having various slope angles.
