Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rooftop soundproof floorboard for reducing the rooftop noise of a building.

[Conventional technology]

In recent years, the number of sports facilities such as golf and tennis practice fields constructed on the rooftop of a building has been increasing, and the influence of noise generated thereby on the downstairs has become a problem.

In particular, the impact sound generated when a ball such as golf or tennis falls on the floor plate sounds remarkably loud, which may lead to noise pollution.

Therefore, conventionally, as shown in FIG. 7, plywood 7 is laid on the upper surface of the concrete slab 4 on the roof of the building,
A surface material 3 such as artificial grass is laid on the upper surface of the plywood 7 to reduce noise.

[Problems to be solved by the device]

However, such conventional floorboards do not sufficiently reduce the impact sound of golf and tennis balls, and because plywood (wood) is used, corrosion is fast and durability is low, so maintenance costs are high, etc. There was a problem.

Therefore, an object of the present invention is to provide a rooftop soundproof floorboard that exhibits a sufficient soundproofing effect against rooftop noise, has high durability, and is easy to apply.

[Means for Solving the Problems]

A resin-laminated steel sheet obtained by compounding a viscoelastic polymer material in a laminate type between a pair of thin steel sheets is called a vibration-damping steel sheet because it exhibits excellent effects in terms of vibration-damping performance. , Is being spread in various fields such as building materials.

The mechanism of noise reduction of such a vibration damping steel plate is already known and will not be described in detail.However, during vibration, the intermediate resin layer undergoes shear displacement due to bending deformation, and vibration energy is converted into heat energy. Then, the vibration of the thin steel plate is attenuated. This vibration-damping steel plate does not produce the high-pitched sound peculiar to the steel plate even when hit.

The inventors have conducted extensive research to prevent noise on the rooftop of the building. As a result, they found that the damping steel plate was applied as a soundproof floor plate for rooftops.

This invention was made based on the above-mentioned findings, and a plurality of ribbed grooved damping steel plates formed of a horizontal flange and L-shaped webs on both sides of the flange,
For mounting the plurality of damping steel plates in parallel with each other,
A groove-shaped connecting lateral stop metal fitting in which two adjacent webs of the plurality of vibration damping steel plates are freely fitted, and the plurality of vibration damping steel plates arranged in parallel on the upper surface of the upper side through the connecting lateral stop metal fitting without a gap. It is characterized by comprising a surface material laid on the upper surface of the.

Next, the invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a soundproof floor board for a roof of the present invention, FIG. 2 is a perspective view of a main part showing a relationship between a vibration damping steel plate and a connecting lateral stopper, and FIG. FIG. 4 is a perspective view showing a main part front view, FIG. 4 is a perspective view showing a connecting lateral stopper fitting, and FIG. 5 is a main part perspective view showing a state in which an end plate steel plate is attached. A surface material is partially omitted in FIG. 1, and an end plate steel plate is omitted in FIG.

As shown in FIGS. 1 to 5, the present invention comprises a damping steel plate 1, a connecting lateral stop metal fitting 2, and a surface material 3.
4 is a concrete slab on the rooftop.

The vibration-damping steel plate 1 is formed in a rip groove shape including a horizontal flange 1a and L-shaped webs 1b on both sides of the flange 1a. Further, the tip 1c of the web 1b is bent inward. The upper surface of the flange 1a has a V for increasing elasticity.
A mold groove 1d is provided.

The connecting lateral stop fitting 2 is made of a groove-shaped steel plate. The webs 1b, 1b of two vibration damping steel plates 1 adjacent to each other can be freely fitted to the inner surface of the flange 2a of the connecting lateral stop fitting 2.

A plurality of connecting lateral stoppers 2 are arranged on the upper surface of the rooftop concrete slab 4 at predetermined intervals, and a plurality of damping steel plates 1 are mounted on the connecting lateral stopper 2 with two webs 1b adjacent to each other. They are placed side by side without any gap.

End plate steel plates 5 are vertically provided on both open side surfaces of the vibration damping steel plate 1 via groove-shaped vertical stoppers 6 to form a space with a concrete slab 4 formed by the vibration damping steel plate 1. It is partitioned.

A surface material 3 such as artificial turf is laid on the upper surface of a vibration damping steel plate 1 which is arranged in parallel on the upper surface of a rooftop concrete slab 4 without a gap.

As the connecting lateral stopper metal fitting 2, as shown in FIG. 6, it is also possible to use one having a shape in which the upper part of the web is curved and inclined toward the outside so as to be expanded to the outside. By using this connecting lateral stop metal fitting 22, the web 1b of the damping steel plate 1 can be smoothly fitted into the connecting lateral stop metal fitting 22.

The damping steel plate 1 used in the present invention has a soundproof effect of 0.
A thickness of about 5 to 6 mm is suitable. For example, a vibration-damping steel plate in which a 0.1 mm rubber-based viscoelastic body is laminated and composited between a pair of 0.6 mm steel plates is used.

In addition, the soundproof floorboard for rooftop of the present invention has a size of one piece of the vibration-damping steel plate 1 of 2 m × 24 cm in consideration of use conditions, workability, etc.
It is advantageous in terms of transportation to have a size of about the same.

The rooftop soundproofing floor plate of the present invention laid on the upper surface of the rooftop concrete slab 4 is firmly fixed by the connecting lateral stop metal fittings 22 and the vertical metal fittings 6, and lateral deviation and vertical deviation are extremely unlikely to occur.

[Effect of device]

Since this device is constructed as described above,
It has the following useful effects.

The vibration-damping steel plate makes it possible to suppress the impact sound from the ball downstairs to an extremely low level, and eliminates noise pollution.

Since the work is just to fit the damping steel plate, which can be easily carried by humans, into the stopper, the work process is omitted, and the workability is extremely good.

Corrosion resistance and durability are dramatically improved compared to wood.

Total cost such as durability, maintenance and workability is low and it is economically excellent.
