Abstract

The invention discloses a medium-long rib prefabricated bottom plate hoisting structure and a construction method thereof. The medium-long rib prefabricated bottom plate hoisting structure comprises structural beams, wherein the structural beams are arranged side by side, a medium-long rib prefabricated bottom plate is in lap joint with the upper parts of the structural beams, detachable angle steel is arranged at the upper edges of the end faces, which face each other, of the structural beams, the end faces of one side of the detachable angle steel are attached to the end faces of the structural beams, the end faces of the other sides of the detachable angle steel are attached to the lower end face of the medium-long rib prefabricated bottom plate, the detachable angle steel is provided with a jacking structure which is used for tightly attaching the detachable angle steel to the medium-long rib prefabricated bottom plate, and a hoisting structure is arranged on the upper end face of the medium-long rib prefabricated bottom plate. Steel pipes with semicircular holes are additionally arranged in the short edge direction of the prefabricated bottom plate, so that the height of materials in the short edge direction of the prefabricated bottom plate is increased, the bending resistance is improved, the problem of damage caused by hoisting in the short edge direction of the prefabricated bottom plate is effectively solved, and additionally, the width of the produced prefabricated bottom plate is large.

Description

technical field [0001] The invention relates to the field of prefabricated assembled concrete structure buildings, in particular to a mid-length rib prefabricated floor hoisting structure and a construction method thereof. Background technique [0002] At present, in the actual prefabricated concrete buildings, the ribbed prefabricated floor has the advantages of prefabricated ribs, good bending resistance, and large applicable span. Therefore, various types of ribbed prefabricated floor are widely used. However, among the many ribbed precast floor structures and construction methods, few involve the hoisting structure of the ribbed precast floor and the connection method between the ribbed precast floor and the beam, and there is a lack of a complete set of construction methods corresponding to the ribbed precast floor. Contents of the invention [0003] The object of the present invention is to provide a medium-long-rib prefabricated bottom plate hoisting structure provi...
