Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a structure for supporting a ceiling plate away from a concrete slab or beam for the purpose of sound and vibration isolation.

(Prior Art) Structures have been known in which the ceiling panels of houses or condominiums are supported away from concrete slabs or beams to reduce noise, vibration, etc. from the floors above.

Specifically, as shown in FIG. 2, an anchor bolt 21 is screwed onto a slab 20, a hanging tool 22 is attached to the anchor bolt 21, and a ceiling board 24 is attached to the lower surface of the field edge 23. Noen Uke 2
5, and the field edge receiver 25 is supported by the lower end of a bolt 27 inserted through the hanging tool 22 via a spring 26.

(Problem to be solved by the invention) In the above-mentioned conventional hanging structure, since the frame support is supported by bolts extending downward from the hanging tool, the interval between the slab 20 and the ceiling board 24 is It must be at least greater than the height of the hanging fixture 22, the length of the bolts 21, 27, and the height of the edge 23 and edge support 25, and as a result, the height of the slab 20 and the ceiling board 24 The gap, that is, the ceiling width increases, and the ceiling plate 24 is relatively lowered, resulting in a problem that the volume of the room becomes smaller.

(Means for Solving the Problems) In order to solve the above problems, the hanging structure of the ceiling board according to the present invention includes forming the main body of the hanging tool in a U-shape, forming an insertion hole in the lower part, A metal fitting is installed through this insertion hole and a through hole provided in an elastic body installed in the main body, and the mounting metal fitting is extended horizontally from this metal fitting, and at least a part of it in the height direction is attached to the above-mentioned hanging metal fitting. A field edge receiver placed eccentrically with respect to the axis of the hanger was fixed so as to overlap with the hanging tool, a field edge was attached so as to intersect with the field edge receiver, and the ceiling board was attached to the lower surface of this field edge.

(Example) An example of the present invention will be described below based on FIG. 1.

Fig. 1 is a partially cutaway side view of the suspension structure according to the present invention. In the figure, 1 is a concrete slab (including a beam), and a hanging device 2 is connected to the concrete slab 1. The board 3 is suspended and supported.
That is, the ceiling board 3 is attached to the lower surface of a field edge 4, and this field edge 4 is attached to the lower surface of the field edge receivers 5 arranged so as to intersect with each other. Supported by 7.

The main body 8 of the hanging tool 2 is formed by bending a metal plate into a U-shape, and an anchor bolt 9 is fixed to the upper surface of the upper plate portion 8a.
The hanging tool 2 is attached to the slab 1 by screwing into the hole-in anchor 10 buried in the slab. A bolt insertion hole 11 is formed in the lower plate portion 8b of the main body 8, and an elastic body 13 provided with an adapter 12 is loaded inside the main body 8. Elastic body 13
has a square block shape, and is made by compressing glass wool 13a and coating the surface with rubber 13b, and has the bolt insertion hole 11 in the center.
A through hole 14 corresponding to the through hole 1 is drilled, and this through hole 1
4 into which the cylindrical portion 12a of the adapter 12 is fitted. A female screw portion is carved into the inner peripheral surface of the cylindrical portion 12a of the adapter, and a circular flange portion 12b is provided at the upper end portion of the cylindrical portion 12a.
2b comes into contact with the upper surface of the elastic body 13.

A bolt 15 is screwed into the cylindrical portion 12a of the adapter 12 from below, and the base end of the mounting bracket 7 is supported by the lower end of the bolt 15 via double nuts 16,16. The mounting bracket 7 has a plate shape, extends in the horizontal direction, and its tip fits into a notch 5a formed in the field edge receiver 5, and supports the upper surface of the notch 5a of the field edge receiver 5 from below with a screw 6.

Here, the field edge receiver 5 is arranged at a position eccentric from the position directly below the hanging tool 2, and the position of the field edge receiver 5 in the height direction is such that at least a part thereof overlaps with the hanging tool 2 when viewed from the horizontal direction. do.

In the illustrated example, a notch 5a is formed in the field edge receiver 5, and the mounting bracket 7 is made to face inside this notch 5a, but the notch 5a is not formed and the mounting bracket 7 is directly inserted into the field edge receiver. The edge support 5 may be supported by screws or the like against the lower surface of the frame support 5. In addition, to finely adjust the vertical position of the mounting bracket 7, use the double nut 1.
6 and 16, and if the amount of adjustment is large, the amount of entry of the bolt 15 into the cylindrical portion 12a may be adjusted.

(Effects of the invention) As explained above, according to the invention, in a structure in which a ceiling board is suspended and supported from a concrete slab or a beam via a hanging tool, the position of the edge support of the ceiling board is set directly below the hanging tool. It is eccentric from the position to the side, and at least a part of the field edge receiver overlaps the hanging tool when viewed from the horizontal direction, and the field edge receiver is supported by a mounting bracket extending horizontally from the hanging tool. Therefore, the space between the slab or beam and the ceiling board, that is, the width of the ceiling, can be narrowed to allow the ceiling board to be suspended and supported, thereby increasing the relative height of the ceiling board while achieving sound and vibration isolation. It is possible to increase the volume of the room.

In addition, it has a vibration-proof structure in which the load of the ceiling plate is applied to the elastic body attached to the hanging body which is bent into a U-shape, and the load of the ceiling plate is maintained through the elastic body.
The hanging tool itself has high durability, and there is no risk that the elastic body will fall off even when subjected to lateral forces such as earthquakes, making it highly reliable.
