Description

この発明は、例えば、鉄道のレールに貼着されて制振材を固定するための固定具および固定方法に関する。   The present invention relates to, for example, a fixing tool and a fixing method for fixing a damping material by being attached to a rail of a railway.

実現場のレールに制振材を貼り付ける防音方法の場合、表面状態が劣悪（錆、ほこり）であるため、接着力の低下や施行不良による制振材の脱落の危険があった。これを防止するために固定具が用いられている。固定具は、レールの両側から板状部材を別々にあてがい、これら両板状部材をボルトおよびナットによって締付けるようにしていた（例えば、特許文献１参照。）。 In the case of the soundproofing method in which the damping material is attached to the rail in the realization field, the surface condition is inferior (rust, dust), so there is a risk of the damping material falling off due to a decrease in adhesive force or poor enforcement. Fixing tools are used to prevent this. In the fixing tool, plate members are separately applied from both sides of the rail, and both the plate members are tightened with bolts and nuts (see, for example, Patent Document 1).

このようなやり方では、施工が煩雑であること、ボルトおよびナットが緩むためにメンテナンスが必要であること等の問題点があった。
特開平１１−１３２２７３号公報 In such a method, there are problems such as complicated construction and the need for maintenance because bolts and nuts are loosened.
