Abstract
The invention discloses a tensioning table base device for a box girder oblique web vertical finish rolling deformed steel bar. The tensioning table base device comprises an upper oblique plate (1). The lower face of the left side of the upper oblique plate (1) is connected with a left side panel (2), and the lower face of the right side of the upper oblique plate (1) is connected with a right side panel (3). The lower face of the middle portion of the upper oblique plate (1) is connected with a left side oblique supporting plate (4) and a right side oblique supporting plate (5). The middle lower position of the upper face of the upper oblique plate (1) is connected with a limiting plate (7). An upper oblique plate circular hole (8) is formed in the center position of the upper oblique plate (1). By means of the tensioning table base device, tensioning of the box girder oblique web vertical finish rolling deformed steel bar can be achieved, and the whole table base structure is good in stress, convenient to use, light, high in tensioning speed and high in work efficiency.
Description
technical field [0001] The invention relates to a box girder vertical finish-rolled threaded steel tensioning platform device. Background technique [0002] The traditional box girder web-only vertical finish-rolled rebar tensioning pedestal is bulky, inconvenient to move and has low work efficiency; The traditional straight web vertical finish-rolled rebar tensioning pedestal is used to be processed into the geometric form of a horse stool. From the structural form, the tensioning force pedestal is easy to deform, and the structural geometric form is an unstable structure. Excessive deformation of the pedestal is harmful to the Tensioning vertical prestress causes loss effect, so a kind of vertical finish-rolled rebar tensioning pedestal device for box girder oblique web is specially developed and designed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a tensioning stand device for the vertical finish-rolled ...
