Embodiment Construction
[0030] like figure 1 , figure 2 , image 3 as well as Figure 4 As shown, the unilateral jacking safety protection device 1 of the large-span reticulated shell structure 3 of the present invention includes a plurality of safety sections 1-1 connected in sequence from top to bottom, and a connection transition is inserted at the upper end of the top safety section 1-1. Pipe 1-3, a supporting rib 1-4 is fixed on the outer side of the connecting transition pipe 1-3, and the supporting rib 1-4 is in contact with the surface of the flange 1-2 at the upper end of the safety joint 1-1, thereby restricting the At the position of the connecting transition pipe 1-3, a semicircular groove 1-11 is opened at the top of the connecting transition pipe 1-3, and a horizontal connecting horizontal pipe 1-5 is placed in the semicircular groove 1-11. Both ends of 5 are provided with U-shaped cards 1-6, the U-shaped cards 1-6 are fixed on the flange 1-2 at the upper end of the safety section 1...

The invention relates to a safety protection device for unilateral jacking of a large-span reticulated shell structure and a safety jacking method. The safety protection device comprises a plurality of safety sections connected in sequence, and a connecting transition pipe is inserted into the upper end of the safety section located at the top. A supporting rib is arranged on the outer side of the connecting transition pipe, the supporting rib is in contact with the surface of the flange at the upper end of the safety joint, a semicircular groove is opened at the top of the connecting transition pipe, and a connecting horizontal pipe is arranged in the semicircular groove. The two ends of the connecting horizontal pipe are provided with U-shaped cards, which are fixed on the flange plate at the upper end of the safety joint, and the two ends of the connecting horizontal pipe are fixedly connected with support ribs, and one side of the support ribs is an arc. A pair of wedge-shaped blocks are arranged below the safety section located at the bottom, and sleepers are arranged below the wedge-shaped blocks. The safety protection device of the present invention can effectively support the reticulated shell structure under the condition that the local jacking device is unstable, so as to avoid the occurrence of accidents.
Description
technical field [0001] The invention relates to a reticulated shell structure jacking technology, in particular to a large-span reticulated shell structure unilateral jacking safety protection device and a safe jacking method. Background technique [0002] In the process of unilateral jacking of the large-span reticulated shell structure, the ball node at one end of the reticulated shell is used as a hinge point, which is located on the support to form a hinge axis as a whole, and the other end is jacked up. The method of unilateral jacking is the largest. The advantages are that workers assemble on the ground, the work surface is large, the work efficiency is high, and the safety risk is small. The disadvantage is that when the jacking device is jacked up, the apex will be displaced horizontally and laterally. If the adjustment is not timely or the external force interferes greatly, the jacking device is easy to become unstable, resulting in safety accidents. At the same t...
