The application relates to the technical field of building construction safety protection, and discloses a center column installation turnover cantilever protection device, which comprises steel belts, angle steels, square steel pipes, bolts, round steel pipes and steel sheet nets, wherein the steel belts are arranged in a plurality of strips, are fixed in a hoop around the outer wall of the center column, and are connected into a hoop clamp through the bolts at the two ends; the angle steels serve as main cantilever beams, the vertical limbs of the angle steels are connected with the steel belts through the bolts, and the horizontal limbs of the angle steels are extended to form a cantilever platform; the square steel pipes are connected at the end portions of the horizontal limbs of the angle steels and form an annular outer frame with the adjacent angle steels; the round steel pipes are arranged in a hoop to form a horizontal support system; and the steel sheet nets are laid on the platform surface as a bottom plate for the walking and material placing of workers. The application can provide a working platform and falling protection device which are directly fixed on the installed center column segment, and solve the problems of high cost, slow erection, high risk in the air and poor turnover in the prior art.

The utility model relates to a truss assembly jig frame, belongs to the technical field of building construction, and particularly relates to an adjustable assembly type truss assembly jig frame which comprises a base transverse rod and a truss and further comprises a base transverse rod. The supporting vertical rods are installed at the bottom of the base transverse rod through bolts in a threaded mode, and a pair of supporting vertical rods are installed on the base transverse rod in a threaded mode; the number of the lug plates is multiple, and the lug plates are arranged on the surface of the base cross rod and one side of the supporting vertical rod; the T-shaped steel plate is welded on one side of the cross rod of the base; according to the utility model, the effects of no need of welding and repeated use are achieved, and the problems that the existing jig frame design is suitable for a conventional truss, but the requirement for supporting a special-shaped structure or an ultra-large span is possibly insufficient, the adjustment depends on a gear rack system, and the locking mechanism is possibly abraded and the risk of loosening is generated due to long-term use or frequent adjustment are solved.
