PURPOSE: A prefabricated streetlamp post is provided to reduce maintenance costs by individually replacing upper and lower posts and to prevent the upper post from being horizontally rotated. CONSTITUTION: A prefabricated streetlamp post is composed of a lower post(1) and an upper post(2). A key groove(3) is formed in the top end of the lower post. Both sides of the key groove are rounded so that a key(4) can be easily inserted. The key is arranged on the bottom inner surface(2') of the upper post. A C-shaped reinforcing cover, which has the same diameter as the outer diameter of the key, is welded in the inner side of the key groove. When the key is inserted into the key groove, the reinforcing cover completely covers the key.
