Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-vibration field edge and anti-vibration ceiling structure.

[0002]

2. Description of the Related Art In a building, in order to prevent vibration of the upper floor from being transmitted to the ceiling material of the lower floor and causing noise in the lower floor space, a vibration-proof ceiling structure with improved sound insulation performance of the upper and lower floors is adopted. There is.

A conventional vibration-proof ceiling structure is disclosed in Japanese Patent Laid-Open No. 55-1.
As described in Japanese Patent No. 32835, ceiling hanging metal fittings are provided on the upper floor floor beams, and the ceiling hanging metal fittings support a field edge having an inverted T-shaped cross section. There are those that place and fix ceiling materials. The ceiling hanging metal fittings are scattered between the upper floor and the lower floor ceiling material, and the vibration propagation path area from the upper floor to the lower floor ceiling material is small, and the vibration from the upper floor to the lower floor ceiling material is reduced. It reduces the transmission of.

[0004]

However, the prior art has the following problems. The work of installing the ceiling hanging metal fittings on the floor beams of the upper floor and the work of supporting the field edge on the ceiling hanging metal fittings are required, resulting in a large number of construction steps. It is necessary to intersperse a large number of ceiling suspension fittings between the upper floor and the ceiling material of the lower floor, resulting in a large number of construction steps.

It is an object of the present invention to simplify the construction and construction of a vibration-proof ceiling structure.

[0006]

The present invention according to claim 1 is an anti-vibration field edge formed by interposing a damping material between the upper field edge material and the lower field edge material and integrating them.

The present invention according to claim 2 provides a vibration-proof ceiling structure in which a lower floor ceiling material is arranged below an upper floor material.
The anti-vibration field edge according to claim 1 is interposed between the upper floor material and the lower floor ceiling material, and the upper field edge material of the anti-vibration edge is attached to the upper floor material,
The lower floor ceiling material is attached to the lower field edge material of the anti-vibration field edge.

[0008]

According to the present invention, there are the following actions. It is only an improvement on the traditional field used to attach the ceiling material, and does not require new construction. The anti-vibration field edge is simply a vibration damping material interposed between the Ueno edge material and the lower field edge material, and has a simple and inexpensive structure. The vibration of the upper floor is damped by the damping material on the edge of the vibration isolation field, and is prevented from being transmitted to the ceiling material of the lower floor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a schematic view showing an example of a vibration-proof ceiling structure, FIG. 2 is a view taken along the line II-II of FIG. 1, and FIG.
FIG. 4 is a schematic view showing an example of an anti-vibration field edge along the line III.

The vibration-proof ceiling structure shown in FIGS. 1 to 3 has the upper floor 11
Is transmitted to the ceiling material 21 of the lower floor to prevent noise in the lower floor space. At this time, the upper floor 11 is a wooden structure, and the floor covering 14 is fixed to the upper surface of the floor frame 13 composed of the floor beams (and floor joists) 12 with an adhesive or nailing.

However, in the present embodiment, the vibration isolation field edge 30 is interposed between the upper floor floor beam (and floor joist) 12 and the lower floor ceiling material 21. As shown in FIG. 4, the anti-vibration field edge 30 includes a damping material 33 interposed between an upper field edge material 31 made of plywood and a lower field edge material 32 made of wooden beams, and these three members are bonded by an adhesive. It is an integrated adhesive. Then, the upper field edge material 31 of the vibration isolation field edge 30 is nailed to the lower surface of the upper floor floor beam (or floor joist) 12, and the lower floor ceiling material 21 is attached to the lower surface of the lower field edge material 32 of the vibration isolation field edge 30. Nailed up.

As the damping material 33 which constitutes the vibration-proof field edge 30, a synthetic rubber, a soft synthetic resin, or a sheet-like material in which a metallic filler such as iron is mixed with a mixture of synthetic rubber and a soft synthetic resin is adopted. it can.

Specifically, the upper floor floor beam (or floor joist)
A plurality of anti-vibration field edges 30 having an interval of 455 mm were provided in the direction orthogonal to 12. At this time, a soft vinyl chloride sheet having a loss coefficient of 3% or more was adopted as the damping material 33.

The operation of this embodiment will be described below. This is merely an improvement of the field edge that has been conventionally used to attach the ceiling material 21, and does not require new construction. The anti-vibration field rim 30 is only integrated by interposing the damping material 33 between the Ueno rim material 31 and the lower rim material 32,
The structure is simple and inexpensive. The vibration of the upper floor 11 is damped by the damping material 33 of the vibration isolation field edge 30 and is suppressed from being transmitted to the lower ceiling material 21.

The anti-vibration field edge 30 is made by attaching a wood-based Ueno edge material 31 to the floor beam (or floor joist) 12 by nailing, and can be easily attached anywhere on the floor frame 13. It is also easy to construct in terms of points.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration of the present invention is not limited to this embodiment, and changes in design within the scope not departing from the gist of the present invention can be made. Even if it exists, it is included in the present invention. For example, (1) the upper floor may consist of a steel frame structure and the steel frame floor material may be attached with the Ueno edge material of the vibration isolation field edge, and (2) the upper floor may have a steel frame structure. The wooden floor joists provided in the floor frame composed of the steel floor beams may be attached with the upper edge material of the vibration isolation field edge. Moreover, it is not always necessary that the upper and lower sill edges of the anti-vibration field edge are made of wood.

Further, in the vibration-proof field edge, the damping material is not integrated with the upper-field edge material and the lower-field edge material by using an adhesive, but by fusion-bonding with the damping material itself in a heat-softened state. It may be

As described above, according to the method of the present invention, the structure and the construction of the vibration-proof ceiling structure can be simplified.
