【考案の詳細な説明】
本考案は、住宅等の上階床面からの衝撃音や上
下階間の透過音を緩和あるいは軽減する床下地構
造に関するものである。[Detailed Description of the Invention] The present invention relates to a subfloor structure that alleviates or reduces impact noise from the floor surface of an upper floor of a house or the like and sound transmitted between upper and lower floors.
床面の防音対策としては、遮音と防振との両者
を考慮する必要がある。 As soundproofing measures for floors, it is necessary to consider both soundproofing and vibrationproofing.
その方法として、弾力性と遮音性とを有するゴ
ムシートや発泡樹脂シートを床下地材の上面に敷
きつめればよいが、一枚のシートで大なる衝撃を
緩和するには厚さが大になり、シートが高価にな
るとともに、大面積のシートを敷きつめることは
作業性が極めて悪いという不具合が生じる。 One way to do this is to lay elastic and sound-insulating rubber sheets or foam resin sheets on the top of the subflooring material, but a single sheet is too thick to cushion a large impact. In addition, the sheets become expensive, and the workability of laying sheets over a large area is extremely poor.
また、ゴム脚等の弾性脚体を設けたパネルを下
地材上に並設して衝撃力を緩和することも考えら

程度の軽衝撃力の緩和には効果を発揮するが、床
上で跳びはねる際に生じる様な重衝撃力に対して
は、パネルが衝撃の反動であばれを生じ易くパネ
ル自体が振動してしまうという問題があつた。 It is also possible to reduce the impact force by installing panels with elastic legs such as rubber legs on the base material. However, there was a problem in that the panel was susceptible to cracks due to the reaction of the impact, causing the panel itself to vibrate when subjected to heavy impact forces such as those generated when jumping on the floor.
本考案は前記の問題点に鑑みてなされたもの

造を提供しようとするものである。 The present invention was developed in view of the above-mentioned problems, and consists of installing a floor panel with a plurality of elastic legs in parallel on the top surface of the subfloor material, and horizontally suspending a plate-like body on the top surface of the floor panel. By fixing the rubber mats in parallel on the upper surface of this plate-like body, the impact force peak generated on the floor by the legs and the rubber mats can be reduced, and the vibration damping effect of the mats can be used to reduce the impact force. The rubber mats prevent the vibration of the floor panels, and the rubber mats block the transmitted sound passing between the floor panels, and the elastic legs prevent vibrations from propagating to the plate-like subflooring material due to the reaction of the impact force. The purpose of the present invention is to provide a subfloor structure that prevents panels from floating or rising by fixing plate-like bodies.
つぎに、本考案を実施例である図面にしたがつ

て目すきあるいは突きつけで固定してある。 FIG. 1 shows a first embodiment of the flooring structure according to the present invention, in which a plate-shaped flooring material 2 made of plywood or particle board is horizontally suspended over the entire surface of a joist 1. A floor panel 3 having elastic legs 4 made of a plurality of elastic bodies such as anti-vibration rubber on the lower surface is fixed to the upper surface of the floor panel 2 by applying adhesive to the elastic legs 4 and fixing the floor panel 3 with an adhesive. be.

弾性と粘着性を有するとともに、硬化後において

の弾性コーキング剤８を充填してもよい。 Then, a plate-like body 5 made of plywood or the like is placed on the floor panel 3 with the joints of the floor panel 3 horizontally placed, and nails 6 are placed.
After sewing, a rubber mat 7 is stuck on the top surface of the plate-like body 5 or a gap of 2 to 3 mm is created. Note that the joints of the rubber mat 7 have elasticity and adhesive properties such as acrylic, silicone, urethane, butyl rubber, etc. to improve the airtightness of the rubber mat 7, and even after curing, the rubber An elastic caulking agent 8 which is softer and more easily deformed than the mat 7 may be filled.

ントロールすることができる。 Further, the rubber mat 7 has a thickness of 5 mm or more,
Preferably, the thickness is 5 to 30 mm from the viewpoint of workability and sound insulation. Furthermore, the specific gravity is preferably 1.4 to 1.7. If the specific gravity is less than 1.4, sufficient sound insulation cannot be obtained unless the thickness of the pine is increased, resulting in poor workability; if it exceeds 1.7, the elasticity of the pine is low, resulting in poor vibration isolation, and the weight of the pine becomes large. This is because the workability deteriorates. In this case, the specific gravity can be controlled by adding metal powder, metal oxide powder, inorganic powder, etc.
なお、ゴム製マツト７の損失係数は、0.2以上
の粘性の高いものが、振動の吸収性が大きく好ま

Then, while microphones were installed on the first floor, an impact was applied to each of the floor surfaces, and the intensity (dB) of the impact sound generated at that time was measured. Figure 3 shows the measurement results when the impact was applied by a tapping machine as a lightweight impact source, and Figure 4 shows the measurement results when the tire was dropped as a weight impact source.
These are displayed in comparison with the JISA1419 sound insulation class of buildings. The data of the present invention is curve a marked with ◎, the data of comparative example 1 is curve b marked with □, and the data of comparative example 2 is curve c with marked x. It is.

地材への振動を効果的に防止して優れた床下地と
することができる。 As is clear from the above explanation, according to the flooring structure of the present invention, a floor panel with elastic legs is provided on the upper surface of the plate-shaped flooring material, and the plate-shaped body is fixed to the upper surface of the floor panel with nails, etc. The panels are joined to each other using a rubber mat with a thickness of 5 to 30 mm on the top surface of the plate-like body.The elastic legs and the rubber mat weaken the impact on the floor, and The vibration of the panel caused by the rubber mat is absorbed by the vibration damping effect of the rubber mat, so the floor panel does not vibrate due to the reaction of the impact force, and the vibration isolation (vibration isolation) of the elastic legs prevents it from vibrating. The effect is fully exhibited, and vibrations to the plate-like flooring material can be effectively prevented and an excellent flooring material can be obtained.
さらに、各床パネルの上面を合板等の板状体で
結合したものであるので、衝撃力が一枚の床パネ

とともに、床パネルの接合部を板状体とゴム性マ

透過音を遮断して遮音性に優れた床下地とするこ
とができるものである。 Furthermore, since the top surface of each floor panel is joined with a plate-like material such as plywood, the impact force is not concentrated on a single floor panel, which reduces the generation of impact noise. Since it is double-covered with a plate-shaped body and a rubber mat, it is possible to block sound transmitted from the joint part and provide a floor base with excellent sound insulation properties.
