ASEISMATIC APPARATUS OF WATER SUPPLY AND DRAINAGE PIPES

摘要

An earthquake-proof apparatus of a pipe for water supply and drainage is provided to make the pipe maintained in the initial constructed state without deformation caused by such external force as an earthquake, depression of a geological stratum, or vibration, to prevent soil from coming into the pipe in installing the apparatus, and to prevent vibration from being given to the lower side from the upper side. An earthquake-proof apparatus of a pipe for water supply and drainage comprises a semicircular pipe support(10) arranged in a state of covering the lower part of the pipe for water supply and drainage; a pedestal part(20) having a pedestal(21) arranged to the lower side of the pipe support in a spaced state; a shock-absorbing part(30) having springs(32) arranged between spring fixing caps(31); and a cover(11) arranged to the top surface of the pipe for water supply and drainage in a close contact state. The pedestal part has a pair of side pedestals(22) whose lower ends are hingably combined with both sides of the pedestal and the side pedestals are installed to both sides of the pipe support in a spaced part. The spring fixing caps are symmetrically attached to the sides and lower part of the pipe support, and to the inside of the pedestals and the side pedestals. The cover has a close contact part(12) to close a space between the pipe support and the side pedestals.
