Abstract

The invention discloses a temporary prestress device for a segmental prefabricated assembled beam. The invention belongs to the field of segmental prefabricated assembled beam installation. The temporary prestress device for the segmental prefabricated assembled beam comprises a pouring column, a column body template and a driving motor, a first section of prefabricated assembled beam is fixedly mounted at the top end of the pouring column; and the column body template is fixedly mounted in the outer side surface of the pouring column. According to the scheme, a hydraulic lifting system composed of a third adjusting rod, a second adjusting rod and a hydraulic rod is arranged, so that the installation height can be conveniently adjusted, installation is convenient, a winding shaft is arranged so that the applied prestress is adjusted to sound a steel rope, so that the tension degree of the prestress applying steel rope can be effectively adjusted, maintenance and installation are convenient, the prestress applying steel rope is extruded and fixed by deforming the fixing shaft, then the position of the prestress applying steel rope can be effectively fixed and positioned, and long-term prestress application is facilitated.

Description

Technical field [0001] The invention relates to the field of installation of segmented prefabricated assembled beams, and more specifically, to a temporary prestressing device for segmented prefabricated assembled beams. Background technique [0002] During the construction of pre-stressed concrete beams constructed by segmental prefabrication assembly method, the glue joints between the prefabricated segments need to be subjected to a certain temporary pre-pressure, so that the epoxy resin sealant is cured under pressure. At present, the anchoring methods used to apply temporary prestress mainly include concrete anchor blocks, movable steel pedestals with embedded U-shaped anchor bolts, and movable steel pedestals with reserved anchoring holes; [0003] The movable steel pedestal for pre-embedded U-shaped anchor bolts. The U-shaped anchor bolts extend out of the surface of the precast concrete section. It is necessary to drill holes in the corresponding position of the formwork, w...
