Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hanging anchor used when hanging various articles from the ceiling of a building or the like.

Conventionally, hanging anchors used when hanging various items from the ceiling of a building, etc., have one end buried in the base of a ceiling slab, etc., or a threaded part cut into one end and attached to the base. It was fixed to the base by screwing directly into the base. However, when fixing by burying, there are disadvantages in that burying the hanging anchor is time-consuming and the anchor position cannot be easily changed after burying.On the other hand, fixing by screwing in In some cases, the suspension has a low hanging strength and is therefore unsuitable for suspending heavily loaded articles.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and an object of the present invention is to provide a hanging anchor that is easy to attach and remove and has high hanging strength.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

In Fig. 1, reference numeral 1 indicates a base made of concrete or the like for fixing the hanging anchor 2, and 3 indicates a steel plate, such as stainless steel, buried in the base l.The steel plate 3 is bent and directed downward. A plurality of dovetail grooves 5 having openings 4 are formed.

The hanging anchor 2 according to the present invention has a head 6 that engages with a dovetail groove 5 formed in the base 1. This head 6 has the same inclination as the angle 0 formed by the pair of opposing side walls 5a, 5a of the dovetail groove 5 described above, and its width dimension 11 is
It is formed into a trapezoidal shape in front view with inclined surfaces 7, 7 smaller than the groove width dimension 12 on two opposing surfaces, and is fixed to the tip of the anchor body 2a by appropriate means. There is.

When attaching the hanging anchor 2 configured in this way to the base 1, after inserting the head 6 of the hanging anchor 2 through the opening 4 of the dovetail groove 5 in the state shown by the chain line in FIG.
When the head 6 of the hanging anchor 2 is rotated by 90° (the state shown by the solid line in FIG. 1) and the anchor body 2a is pulled downward, the inclined surface 7° 7 of the head 6 is aligned with the dovetail 5. side wall 5a of
, 5a in a wedge-like manner, and is fixed by screwing the nut 2c for preventing backtracking.

FIG. 1 shows an embodiment in which a hanging anchor 2 according to the present invention is used to suspend and arrange a crosspiece 8 for supporting a ceiling panel (not shown) on a ceiling. In this case, the entire length of the rod-shaped anchor body 2a is threaded, and the thread constitutes the support means 9. Therefore, the above-mentioned crosspiece 8 can be disposed on the ceiling simply by fixing both ends thereof to the auxiliary tool IO screwed onto the screw of the anchor body 2a.

2 and 3 show a second embodiment of the hanging anchor 2 according to the present invention, in which a reinforcing member 11 is fitted into the anchor body 2a of the hanging anchor 2. The plate material 12 of the reinforcing tool 11 is formed of a thin iron plate or the like with a generally U-shaped cross section and an open end widened, and a reinforcing plate 13 is fixed to the upper edge of the plate material 12.

In order to attach the hanging anchor 2 according to this embodiment to the base 1, first, as shown in FIG. 3(a), the plate 12 is elastically bent and inserted through the opening 4 of the dovetail groove 5. Third
As shown in Figure (b), the plate material 12 expands due to its restoring force and comes into contact with the side walls 5a, 5a of the dovetail groove 5. After this, the anchor body 2a is further pushed upward, the head 6 is rotated 90 degrees (Fig. 3(C)) to the state shown in Fig. 3(d), and the anchor body 2a is further pulled downward. , the inclined surface 7° 7 of the head 6 presses the reinforcing plate 13 of the reinforcing tool II laterally, and the inclined surfaces 7, 7 press the side wall 5a of the dovetail groove 5 through the reinforcing plate 13,
It is fixed in a state where it is in contact with 5a.

In this way, the inclined surfaces 7, 7 of the head 6 and the side wall 5a of the dovetail groove 5
, 5a through the reinforcing plate 13,
Side wall 5a of dovetail groove 5.

The load area applied to 5a becomes larger, and deformation and damage to the side walls 5a, 5a can be prevented.

FIG. 4 shows an embodiment of a hanging anchor 2 used when hanging articles with a small load from a ceiling, a shelf, or the like.

In this case, the lower end of the hanging anchor 2 is bent into a hook shape to form a support means 97, so that an appropriate article can be suspended from the support means 9.

On the other hand, in the base 1 of the ceiling panel or shelf board, a plurality of holes 14 are bored at predetermined intervals and widen upward, and the holes 14 have an inclined side wall as shown in FIG. 4(c). 5
A holder 15 having short dovetail grooves 5 formed with a and 5a on two opposing surfaces is fitted.

Therefore, in order to suspend an article from a ceiling panel or the like, the hanging anchor 2 may be attached to the dovetail groove 5 located at a required location in the same manner as shown in FIG.

Since the present invention is configured as described above, it is not only easy to attach and remove from the base, but also has extremely high hanging strength compared to the fixing method of screwing bolts etc., and can be used over a wide range. It has great utility value.
