Problems solved by technology
The manufacture of the hollow slab girder pedestal is labor-intensive and time-consuming, and wedge-shaped blocks are installed at the bottom of both ends of the beam to adjust the transverse slope and longitudinal slope of the beam body. Coupled with the influence of the intersection angle of the beam body, the production of the pedestal is quite troublesome

Embodiment Construction
[0018] see figure 1 , the structural form of the highway hollow slab beam combined movable pedestal in the present embodiment is: a reinforced concrete pedestal foundation 5 is set, and the pedestal foundation 5 is set as a "convex" shape on the front section seat, the middle section seat and the rear section seat along the length direction , the top steel plate 6 laid on the pedestal foundation 5 and the pedestal foundation 5 respectively form a front section cavity and a rear section cavity at the positions of the front section seat and the back section seat.
[0019] In the cavity of the front section, the plane sand body 2a satisfying the vertical and horizontal slope is formed by filling fine sand, and the front steel plate 7a is set on the plane sand body 2a; the front section of the top steel plate 6 is supported by the front steel plate 7a;
[0020] In the cavity of the back stage, the step surface sand body satisfying the longitudinal and transverse slopes is formed b...

Abstract
The invention discloses a combined moving pedestal for road hollow-slab beams. The combined moving pedestal provided with a reinforced concrete pedestal base is characterized in that a front base, a middle base and a rear base form a lengthwise T-shape of the pedestal base, a top steel plate laid on the pedestal base forms a front cavity and a rear cavity, respectively with the front and rear bases of the pedestal base, the front cavity is filled with fine sand and provided with a front steel plate, the rear cavity is filled with fine sand to form a stepped sand member, a lower stepped sand member is provided with a rear steel plate, a length-adjustable upper stepped sand member is adapted to the middle of the pedestal base, and the top steel plate is disposed on the moving pedestal. The combined moving pedestal is, in certain range, applicable to production of road hollow-slab beams different in length.
Description
technical field [0001] The invention relates to a construction platform for hollow plate beams of highways. Background technique [0002] The production of highway hollow slab beams is generally carried out on the pedestal, including steel bar binding, vertical formwork, pouring concrete, tensioning and grouting, and curing. However, in highway engineering, the beam spans need to be designed with different intersection angles according to the site topography, so the beam lengths of hollow slab beams with the same span are not the same. The manufacture of the hollow slab beam pedestal is labor-intensive and time-consuming, and wedge-shaped blocks are installed at the bottom of both ends of the beam to adjust the transverse slope and longitudinal slope of the beam body. Coupled with the influence of the intersection angle of the beam body, the production of the pedestal is quite troublesome. Contents of the invention [0003] In order to avoid the disadvantages of the above...
