Title: Soundproof wall having concrete support and the method
Inventor: KANG HYUN SUK
IPC: E02D27/42
Filed: 2021-05-04
Abstract: The present invention relates to a soundproof wall pillar and a construction method for the same. The soundproof wall pillar can shorten a work process since an existing process of fixing a pillar to a fixed foundation by coupling an anchor bolt and a nut is unnecessary as the soundproof wall pillar is applied with a method of directly embedding and fixing a lower end of the pillar into the fixed foundation. Also, the soundproof wall panel maintains a strong fixing force in comparison with a coupling method of the anchor bolt and the nut by direct embedment of the pillar. Moreover, the soundproof wall panel reduces a risk of an accident and improves work convenience by having the light pillar. The soundproof wall panel also improves construction efficiency of a soundproof wall by reducing manufacturing costs since the anchor bolt, the nut, a support plate, and a rib are not used. To achieve the purpose of the present invention, the soundproof wall pillar supports a soundproof plate so that a piled state of the soundproof plate performing a soundproof function and a sound absorbing function is maintained as the soundproof wall pillar is erected vertically on the fixed foundation. The soundproof wall pillar includes: multiple fixing posts integrated in a shape of being asymmetric to each other; and a coupling unit coupling the multiple fixing posts in the vertical longitudinal direction and maintaining mutually complementary erection on the multiple fixing posts.
