Abstract
The invention relates to a cradle construction device replacing a reinforced concrete beam bottom protection layer and a cradle construction method. The cradle construction device comprises angle steel pieces and hook bolts. The two angle steel pieces are welded together at the position close to two end faces of the angle steel pieces through two straight-strip-shaped steel connecting plates, and a straight joint is formed between the two angle steel pieces. The hook bolts penetrate through the straight joint of the two angle steel pieces. Threads which are matched with adjusting nuts in size are arranged on straight hook parts of the upper portions of the hook bolts in a machining mode. The adjusting nuts can rotate at the positions of the straight hook parts, where the threads are machined, of the upper portions of the hook bolts. Square steel base plates are installed between the adjusting nuts and the angle steel pieces, the straight hook parts of the upper portions of the hook bolts penetrate through central holes of the square steel base plates, and bent hook parts of the lower portions of the hook bolts can hook vertical reinforcing ribs. The cradle construction device is easy to manufacture, convenient to install, strong in pertinence and simple to operate, improves construction efficiency, guarantees project quality and reduces project cost.
