[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deck insert which is attached to a deck plate arranged on a ceiling or the like and is used for suspending a channel or an angle member for attaching a ceiling material or the like.

[0002]

2. Description of the Related Art For attaching a hanging tool to a deck plate, there are known a hanging type utilizing the cross-sectional shape of the deck plate and a hanging type attaching an opening in the deck plate. The present invention belongs to the latter type.

The earliest type of mounting the deck plate through the opening is to fix a long bolt to the opening of the deck plate through a washer. Since adjustment of the hanging position is complicated in this type, insert metal fittings are attached to the opening of the deck plate in advance by fixing means using springs, and bolts of arbitrary length can be attached to the insert metal fittings. It came to be used the model of attaching. Such types of deck inserts are described in Japanese Utility Model Laid-Open No. 58-130502, Japanese Utility Model Laid-Open No. 5-54701 and the like.

[0004]

In the deck insert described in the above publication, the length of the insert metal fitting protruding into the deck plate and embedded in the cast slab concrete is constant. Therefore, for example, in the case of placing a heat insulating material on the deck plate and placing concrete on this heat insulating material, use a deck insert with insert metal fittings that are as long as the thickness of the heat insulating material. You have to do it. Therefore, it is necessary for the manufacturer of the deck inserts to prepare various types of insert fittings having different lengths, which is inconvenient in terms of inventory management.

In the technique described in Japanese Utility Model Publication No. 8-10090, in the above case, the length of the insert fitting is always constant, but the length of the fixing means for fixing the insert fitting to the deck plate is adjusted. And is adapted to accommodate different thicknesses of insulation. That is, a plurality of overhanging pieces that are locked to the lower side of the deck plate are prepared, and the overhanging pieces of the first or second step are deformed while being forcedly inserted into the through holes provided in the heat insulating material to form two steps. The structure is designed so that the lower side of the deck plate is supported by the projecting pieces of the third to third steps so that the spring of the fixing means works, and the difference in the thickness of the heat insulating material is dealt with. According to this technique, for example, in the mode in which the lower side of the deck plate is supported by the overhanging piece in the first stage, the overhanging pieces in the second and third steps are unnecessary, and in the aspect in which the overhanging piece is supported in the second stage, It is not preferable from the viewpoint of resource saving because the third overhanging piece is unnecessary.

[0006] In view of the above, the present invention is advantageous in inventory management as a position on the side of manufacturing and selling deck inserts,
Another object of the present invention is to provide an improved deck insert that does not have any inconvenience in terms of resource saving.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a deck insert according to the present invention will be described with reference to FIG. The deck insert 10 according to the present invention comprises an insert metal fitting 11 and a fixing means 12 for fixing the insert metal fitting 11 to an opening 21 prepared in the deck plate 20. Fixing means 12
Has a hollow portion 13 for inserting and holding the lower part of the insert fitting 11, and has a tubular body 15 having a flange 14 at the upper end, and is attached to the outer periphery of the tubular body 15, and the flange 14 and the movable plate 1 are attached.
6, a spring 17 for urging in the direction of separating the 6 and the tubular body 15.
And a support member 19 which is fixed near the lower end of the deck plate and supports the lower side of the deck plate 20 at the tip of the overhanging piece 18.

To attach the illustrated deck insert 10 to the deck plate 20, a circular opening 21 is preliminarily formed in the mountain portion of the deck plate 20. The diameter of the opening 21 is set so that the base end of the support member 19 can be inserted.

To attach the deck insert 10 to the deck plate 20 as shown, the deck plate 20
The lower end of the support member 19 is inserted from the upper side of the opening 21 provided in the and is strongly pushed downward. Then, the overhanging piece 18 of the supporting member 19 passes through the opening 21 while deforming, and returns to the open state again as shown in the drawing. If the insertion is stopped in this state, the movable platen 16 acts in the direction pressing the deck plate 20 by the urging force of the spring 17, so that the deck plate 20 is supported between the deck plate 20 and the supporting member 19 which supports the deck plate 20 from below. Is strongly sandwiched, and the tubular body 15 is fixed. Therefore, the insert fitting 11 held by the tubular body 15 is arranged at a predetermined height position from the deck plate 20.

A lower side of the insert fitting 11 is hollow, and a female screw is provided in this hollow portion. Therefore, by engaging the male screw of the bolt 30 with this female screw, the ceiling plate or the like can be suspended.

The insert fitting 11 is inserted into the hollow portion 13 of the tubular body 15 up to the position of the stopper 13A,
A plurality of types of insert metal fittings 11 having different lengths from the lower end to the head are prepared. Therefore, as shown in FIG. 1, in a mode in which concrete is poured directly above the deck plate 20, a relatively short insert fitting 11 is used. For example, a heat insulating material or the like is arranged on the deck plate 20. In the embodiment, the insert fitting 11 having a length corresponding to the thickness of the heat insulating material is used. Further, the insert metal fitting 11 having an appropriate length is used corresponding to the setting in the situation of the concrete burying depth for maintaining the strength.
