Hoisting structure of UHPC short rib precast slab
The invention discloses a hoisting structure of a UHPC short rib precast slab, which comprises a UHPC short rib precast slab, a plurality of internal thread hoisting connecting devices are symmetrically embedded in the upper plane of the UHPC short rib precast slab with the central axis as the symmetry axis, and a rigid hanging bracket is arranged on the upper plane of the UHPC short rib precast slab and tightly attached to the UHPC short rib precast slab. The rigid hanging bracket is connected with the UHPC short rib precast slab into a whole after being connected with the internal thread hoisting connecting device through the connecting rod, and hoisting equipment hooks the rigid hanging bracket to hoist the UHPC short rib precast slab. According to the hoisting structure of the UHPC short rib precast slab, the cross arm, the screw rod and the internal thread hoisting connecting device pre-buried in the UHPC short rib precast slab are closely connected between the rigid hanging bracket and the UHPC short rib precast slab, and the rigid hanging bracket and the UHPC short rib precast slab are connected into a whole, so that the rigidity of the UHPC short rib precast slab is enhanced; and the phenomena of difficult demolding, cracking of the bottom of the prefabricated slab and the like caused by too large deformation of the UHPC short rib prefabricated slab in the hoisting process are avoided.
本发明公开了一种UHPC矮肋预制板吊装结构，包括UHPC矮肋预制板，所述UHPC矮肋预制板上平面以中轴线对称预埋有若干个内螺纹吊装连接装置，在UHPC矮肋预制板上平面贴紧UHPC矮肋预制板设置有刚性吊架，所述刚性吊架通过连接杆与内螺纹吊装连接装置连接后与UHPC矮肋预制板连接成一整体，起吊设备钩吊刚性吊架实现UHPC矮肋预制板吊装。本发明的UHPC矮肋预制板吊装结构，刚性吊架与UHPC矮肋预制板之间采用横担、螺杆与预埋在UHPC矮肋预制板内的内螺纹吊装连接装置密贴连接，刚性吊架与UHPC矮肋预制板连接形成整体，加强了UHPC矮肋预制板的刚度，避免了UHPC矮肋预制板在吊装过程中因变形太大导致脱模困难、预制板底部开裂等现象。
