Method for constructing shape steel telescopic device for elevated highway bridge floor
The invention discloses a method for constructing a shape steel telescopic device for an elevated highway bridge floor. The telescopic device is structurally axially symmetrical, a Z-shaped steel beam is installed on the upper portion of the telescopic device, the two ends of a rebar ring are welded to backrests on the two sides of the steel beam respectively, a ring body of the rebar ring penetrates the bottom of the steel beam, an L-shaped embedded steel bar is welded to the outer side of the rebar ring, and a trapezoidal ribbing steel plate is welded to the edge of the steel beam. A layer of quick concrete is poured from the bottom of the ribbing steel plate to the bottom surface of the Z-shaped steel beam, a layer of elastic concrete is poured on the upper portion of the quick concrete and is poured to be level with the bridge floor of an elevated highway bridge. During the construction, the telescopic device installation and bridge floor pavement are performed simultaneously, the quick concrete is poured in a reserved groove of the telescopic device; and after asphalt is spread, the groove is cut again and removed and filled with elastic concrete. Because the telescopic device installation and bridge floor pavement are performed simultaneously, concrete of the telescopic device and the bridge floor pavement can be fully maintained, hidden engineering danger is reduced, the construction quality is guaranteed, and the maintenance cost after completion is reduced.
