Description

[Detailed description of the device]

[0001]

[Industrial application] The present invention is designed to be installed under a deck plate with a trapezoidal cross section that is stretched on the ceiling of a concrete building.
The present invention relates to a means for attaching a hanging member to a lower surface of a deck plate for suspending a ceiling plate, a pipe, an air conditioning duct and the like with the hanging member.

[0002]

2. Description of the Related Art Conventionally, as a means for attaching a suspension member such as a long bolt and a stretchable suspension rod to the lower surface of a deck plate, a means for welding one end of the suspension member to a flat portion of the deck plate is generally adopted. .

[0003]

However, this conventional welding means is troublesome and troublesome as a field work, and the thickness of the deck plate is 0.8 to 1.6 mm.
Since it is thin, the welding strength is weak because the welding is often not performed due to the possibility of fusing during welding work, and even when sufficient welding is possible, when a heavy object is hung by the hanging member. In some cases, the deck plate was bent and it was not possible to suspend it in the normal position. It is an object of the present invention to provide an attachment means that can easily attach a suspension member to a deck plate and that has high suspension support strength.

[0004]

Means for Solving the Problems As a means for achieving the above object, the present invention provides a pair of locking plates having a locking bit projecting at one end and a flange at the other end, and the flange end portions. When the two locking plates are opened in a straight line, the width between the locking bit end portions of both locking plates is approximately equal to the bottom width of the valley of the deck plate. Both flanges, when the two locking plates are opened in a straight line,
Suspended for mounting on a deck plate, which are in a positional relationship of abutting against each other to prevent further opening, and which are equipped with bolts and nuts for fastening both flanges in abutting state and connecting one end of the suspending member Suggest a bracket. An embodiment of the present invention will be described below with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 and 2, the hanging bracket of the present invention is a bracket body (1) shown in FIGS.
And the tightening bolt (2) and nut (3) shown in FIG.
Composed of and. The bracket body (1) is a pair of rectangular plate-like locking plates (4), (4) hinge-connected, and the locking plates (4), (4) are rectangular locking plate bodies (5). ) Each has a locking bit (6) projecting from one end, and a flange (7) having a bolt through hole (8) projecting from the other end at a right angle to the main body (5). The hinge joint plates (9), (9) and (10), (10) are provided at the left and right ends of the flanges (7), (7) of the main body (5), (5), respectively, and these joints are provided. The plates are hingedly connected by a hinge shaft (11).

In this case, the pair of locking plates (4),
When (4) is opened in a straight line as shown by a virtual line in FIG. 1 (a), the locking bits (6), (6) of both locking plate bodies (5), (5) are opened. The width between the two ends is
The lower surface of the deck plate (P) shown in (a) and (b) is made substantially equal to the bottom width (d) of the trough (V).

Further, the flanges (7) and (7) are
When the pair of locking plates (4), (4) are opened from the state shown by the solid line in FIG. 1 (a) to the straight line of the imaginary line, they abut against each other and the locking plates (4), (4) ) Is in a positional relationship that prevents further opening.

The operation of the above example will be described below together with a usage example. As shown in FIG. 3 (a), with the locking plates (4) and (4) of the bracket body (1) opened at 90 degrees, the tips of both locking plates (4) and (4) are connected to the deck plate ( The lower surface of (P) is brought into contact with the bottom surface of the trough (V), and in that state, the hinge connecting portion of the bracket body (1) is pushed upward to bring the tips of both locking plates (4) and (4) into the trough ( V) While sliding on the bottom surface, expand the opening angle of both locking plates (4), (4) and finally push until both locking plates (4), (4) form a straight line. When unfolded, both locking bits (6) and (6) at the end of the locking plate are located on the left of the bottom of the valley (V), as shown in FIG.
Engage and lock into the right-hand corners. In this case, when pushing up the hinge connecting portion of the bracket body (1),
As the opening angles of the two locking plates (4) and (4) expand, the pressing force of the two locking bits (6) and (6) in the horizontal direction increases, so that the locking bits (6). , (6) easily bite into the deck plate (P) member. In that state, the fastening bolt (2) is passed through the bolt through holes (8), (8) of both flanges (7), (7), and the upper end of the suspension rod (R) is attached to the protruding portion of the bolt (2). After locking the parts, the nut (3) is screwed and the flanges (7) and (7) are fastened.

The above bracket is provided with both locking bits (6),
Since it will be supported by both side wall portions (S) and (S) of the valley portion of the deck plate (P) via (6), it is possible to suspend a considerably heavy object on the suspension rod (R). It will be possible.

When it is desired to change the mounting position of the suspension rod (R), the fastening bolts (2) and nuts (3) are removed, and the hinge connecting portion of the bracket body (1) is pulled downward to lock them together. If the opening angles of the plates (4) and (4) are fitted, both the locking bits (6) and (6) will be separated from the biting part.

As another embodiment of the present invention, an example in which the margin of the locking bits (6) and (6) can be adjusted can be obtained. As an example, the structure is such that a pin having a locking bit at its tip is slidably held on the locking plate body, and the rear end of the pin is pushed forward and backward by an adjusting screw.

[0012]

[Effects of the Invention] According to the suspension bracket to be mounted on the deck plate of the present invention, both locking plates can be locked to the deck plate by a simple operation of abutting against the deck plate and expanding, and detached from the deck plate. Also, after locking, it will be supported by both side walls of the valley of the deck plate via the locking bits of both locking plates, so mounting with high suspension strength can be realized. .
