2. Description of the Related Art Metal fittings used for mounting a ceiling base, equipment piping, etc. on a steel folding plate are insert metal fittings that are fixed and fixed at a predetermined position of a formwork before placing concrete concrete. , There is a hole anchor that is used by driving it into a predetermined position after pouring concrete.

[0003]

Since the position of the insert metal fitting is determined before the concrete is poured into the frame, it is difficult to deal with design changes and the hole anchor is driven by using a special device. It takes a lot of work to perform.

Moreover, since they are embedded in the skeleton concrete, they are not very flexible, and even if the metal fittings are slightly inclined, the inclination of the supporting members screwed into the metal fittings is significant. It may be difficult to install due to deviation.

The present invention was conceived in order to solve the above-mentioned conventional problems, and the purpose thereof is to be able to fit and mount in the lower groove of a steel folding plate when necessary, and to mount it after mounting. Also in the above, it is to provide a new universal hanging metal fitting that can freely change the angle of the inner threaded metal fitting, and a method of mounting the metal fitting.

[0006]

One of the features of the present invention according to the above object is that a supporting piece is provided at the lower center of a main body having a quadrangular cross section, and an inner screw metal fitting is movable on the supporting piece. It is a free hanging metal fitting that is axially mounted and has an engaging piece of a required width protruding from the center of both sides of the main body, the end surface of which is formed in a reverse taper.

Another feature of the present invention is that while a steel folding plate such as a deck plate is formed into a dovetail groove in cross section,
A flexible hanging metal fitting to be attached to the steel folding plate, a main body with a quadrilateral cross section and an inner threaded metal fitting movably hung downward
The end faces protruding from the center of both sides of the main body consist of engaging pieces with reverse taper of the required width, and the free hanging metal fittings are coated with adhesive on the main body and inserted into the lower groove of the steel folding plate in parallel. Then, the main body is brought into contact with the top plate and is rotated in the lateral direction to engage the engaging piece with the tapered side surface of the lower groove, and by the engagement and fixing with the adhesive, the free hanging metal fitting is made of a steel folding plate. It is in the method installed in.

[0008]

[Operation] In the above free hanging metal fittings, the inner threaded metal fittings are movably attached to the support piece, so the direction of the inner threaded fittings is not limited to one direction, and the support rods within the allowable rotation range, etc. Can be connected.

With respect to the steel folding plate, since the main body is fixed to the top plate of the lower groove with an adhesive, natural disengagement and lateral displacement of the engagement due to vibration are prevented, and the mounting position remains unchanged. , Can hold its position for a long time.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 in the drawing denotes a universal hanging metal fitting, in which a supporting piece 3 is provided at the lower center of a main body 2 made of a hollow steel material having a quadrangular cross section. A cap nut-shaped inner screw fitting 5 having a connecting piece 4 integrally formed on the upper portion thereof is attached to the supporting piece 3 by pivotally mounting the connecting piece 4 with a rivet 6.

Further, engagement pieces 7, 7 having a required width and having an end surface formed in an inverse taper are provided at the central portions on both sides of the main body 2 in a protruding manner.
The engagement pieces 7, 7 are formed with both ends of a steel material 8 having a plane shape molded into a boat shape, and the steel material 8 is inserted into the main body and protruded from both sides of the main body.

As shown in FIG. 2, such a free hanging metal fitting 1 is attached to a steel folding plate 9 such as a deck plate, a support rod 10 is screwed to an inner screw metal fitting 5, and a ceiling base material 11 is attached.
It can be used as a hanging metal fitting. In this case, the cross-sectional shape of the steel folding plate 9 is formed into a dovetail groove shape, and the lower groove 1
2, the main body 2 of the free hanging metal fitting 1 and the engaging pieces 7, 7 are accommodated, and the end surfaces of the engaging pieces 7, 7 are tapered side surfaces 13, 13.
Contact with.

FIG. 3 and subsequent figures show the procedure for attaching the flexible hanging fitting 1 to the lower groove 12. First, an epoxy adhesive 14 is applied to the top plate of the main body 2. Next, the main body 2 is inserted into the lower groove 12 in parallel with the lower groove, and the top plate is strongly abutted on the top plate 15 of the lower groove 12 via the adhesive 14.

After the contact, as shown in FIG. 4, the main body 2 is horizontally rotated horizontally by about 90 degrees. As a result, the engagement pieces 7, 7 on both sides are engaged with the tapered side surfaces 13, 13 of the lower groove 12, as shown in FIGS. 5 and 6.

When the adhesive 14 hardens and the top plate of the main body 2 and the top plate 15 of the lower groove 12 adhere to each other, the main body 2 cannot rotate. The engaging pieces 7 and 7 disengage from the tapered side surfaces 13 and 13,
The free hanging bracket 1 does not fall off the steel folding plate 9.

Although the boat-shaped steel material 8 in the main body 2 is integrally welded to the main body 2, it may be left fitted in some cases, and at this time, after the attachment, before the adhesive 14 is hardened. If so, the main body 2 can be slid using the steel material 8 as a guide to correct the lateral position.

Further, in the universal hanging metal fitting 1 of the present invention, if the receiving metal fitting is formed in the shape of a dovetail groove into which the main body 2 and the engaging pieces 7, 7 can be inserted and engaged, the receiving metal fitting is held by the body side Since it can be attached to a steel folding plate, it is not limited to a steel folding plate.

[0018]

As described above, according to the present invention, the support piece 3 is provided at the lower center of the main body 2 having a quadrilateral cross section, and the inner screw fitting 5 is movably attached to the support piece 3. , The free hanging metal fitting 1 is constructed by projecting engaging pieces 7, 7 of which the end faces are formed in a reverse taper at the center portions on both sides of the main body 2, and the steel folding plate 9 has a dovetail groove-shaped cross section. Since the free hanging metal fitting 1 is formed on the lower groove 12 of the steel folding plate 9 by both engagement and adhesion, the following effects are obtained.

The inner screw fitting attached to the lower side of the main body is
Since it moves to the left and right with the shaft attachment part as a fulcrum, its direction is not limited to one direction, and it is possible to connect the support rod and the like within the rotation allowable range, so there is no particular problem even if the main body is installed at an inclination. It never happens.

Since the main body can be engaged by simply inserting the main body into the dovetail-shaped receiving metal fitting and rotating it horizontally, no special means is required for the mounting operation, and the mounting can be done by groping. Therefore, the mounting work can be completed in a short time.

Since the adhesive is also used to engage in the lower groove of the steel folding plate, the main body does not naturally rotate due to vibration and the engaging piece does not come off the tapered side surface, and the engaging state does not change. It can be maintained for a long time.

Since it can be attached to the steel folding plate when the ceiling base is constructed, it can be adapted to design changes, and the installation work is easier than when using insert fittings or hole anchors. As a result, the cost is significantly reduced in combination with labor saving.
