Furthermore, the end part of the screw rod inclined strut is propped against a steel bar embedded in the bottom plate to resist the lateral pressure of cast-in-place concrete.
Furthermore, the main beam and the secondary beam are connected through high-strength bolts, so that the shearing resistance is high.
Further, the secondary beam is arranged according to the longitudinal interval of the full support, the support bottom support falls on the central line of the secondary beam, and the structure adaptability and the stability are strong.
Further, raise the stand, raise the girder, raise the overhead part that the secondary beam is constituteed and through the rational distribution interval, avoid excavation supporting steel bracing.
Further, the bracing sets up in raising the stand and raising between the girder, and the part stability is raised in the reinforcing.
Furthermore, the stay bar is arranged between the upright post and the inclined strut, so that the stability of the upright post during pouring is enhanced.
Furthermore, the secondary beam is manufactured into a through long form at the foundation-pit-free support steel inclined strut section, and the lifting part is not required to be arranged.
Furthermore, the tripod is made of channel steel in a welding mode, and stability is high.
Furthermore, the cross braces are made of angle steel and arranged between the tripods, so that the stability of the frame body is enhanced.
The invention has the beneficial effects that:
the movable support platform suitable for the box type structure is reasonable in structure, rapid in field assembly and high in practicability, and the elevated part ingeniously avoids a foundation pit supporting structure, so that the problem that the traditional full-hall support is irregularly erected in the area is solved; the platform is matched with the self-locking hydraulic jack and the lifting movable trolley to work, so that the stability under the condition of large load during pouring can be met, the integral formwork erecting, formwork removing and moving operation of a large-span formwork support system can be realized, and the construction efficiency is improved; platform assembly and full framing set up one shot forming, follow-up need not to dismantle the adjustment repeatedly, reduces personnel's input by a wide margin, effectively reduces high altitude construction volume.
