AI Technical Summary
During the dismantling of the steel structure roof, the lack of stable safety cable anchors led to uncertainty in the safety of construction workers.
Safety columns are installed on the steel structure roof, and safety cables are fixedly installed through the safety columns to form an I-shaped safety cable structure, including ridge safety cables, eaves safety cables, and movable safety cables. Together with the safety belts of the construction workers, this ensures the safety of the construction workers during the demolition process.
This allows construction workers to operate flexibly throughout the entire demolition process, ensuring construction safety and avoiding the risk of falling due to excessively long safety cables.

TECHNICAL FIELD
[0001] The utility model belongs to the field of steel structure building, relates to a steel structure roof dismantling structure, in particular to a safety cable structure in steel structure roof dismantling. BACKGROUND
[0002] The plant of steel structure building is the common building structure in industrial building, many large-scale warehouse, production base, power plant all adopt steel structure building, the interior space span of steel structure building is big, the space utilization is good, and can be on site fast erection, disassembly and maintenance, the mode is flexible. The roof of large-span steel structure building plant adopts steel truss erection, then the purlin is laid on the top of steel truss, and the roof panel is laid on the purlin. Under normal circumstances, the roof panel has enough bearing capacity and can be walked by construction personnel. When the roof needs to be maintained or the equipment in the plant needs to be hoisted from the roof, the roof needs to be dismantled, and the roof panel needs to be sequentially removed during construction. During the dismantling process, the roof panel is removed from above by the construction personnel, and the steel truss and the purlin are removed from below. During the dismantling process, the connection of the roof panel is damaged, the bearing capacity of the roof is uncertain, and the construction personnel need to have enough safety measures when working.

In addition, the safety cables are flexible in construction range due to their sliding property.
[0004] The utility model adopts the technical scheme that a safety cable structure in steel structure roof dismantling, the roof sequentially comprises a steel truss, a purlin and a roof panel from bottom to top, the roof has a to-be-removed area, one end of the to-be-removed area near the ridge is provided with corbels outward on two columns on both sides of the to-be-removed area, the two corbels are both fixedly installed with fixed columns upward, and a ridge safety cable is arranged between the top portions of the two fixed columns. One end of the to-be-removed area near the eave is provided with corbels outward on two columns on both sides of the to-be-removed area, the two corbels are both fixedly installed with fixed columns upward, and an eave safety cable is arranged between the two fixed columns. An active safety cable is arranged between the ridge safety cable and the eave safety cable, the two ends of the active safety cable are buckled on the ridge safety cable and the eave safety cable by means of a quick release buckle, and a safety belt on a construction personnel is buckled on the active safety cable by means of the quick release buckle.
[0005] During the dismantling process of the roof structure, the roof panel is dismantled from above, and during the dismantling, the area to be dismantled is sequentially dismantled from high to low from the ridge side to the eave side, and the roof panel at the same height is sequentially dismantled from left to right or from right to left. Therefore, during the dismantling process, the construction personnel will work in sequence from high to low, and each height will be gradually constructed horizontally, and the construction steps will cover the entire area to be dismantled, therefore, the safety cable must adapt to the activity requirements in the entire area to be dismantled, and cannot be too long because the activity range is too large, and cannot play the role of preventing falling. In the application, the fixed transversely arranged ridge safety lock and eave safety lock are used, and the movable safety cable at both ends slides transversely along the ridge safety lock and eave safety lock, forming a safety cable structure in the shape of an I-shaped beam, and the movable safety cable connected in the middle can move transversely, and the active buckle of the safety belt of the construction personnel moves longitudinally on the movable safety cable, forming a safety cable system that can move and adjust longitudinally and transversely, ensuring the safety of the construction personnel, and allowing the construction personnel to flexibly work in the entire area to be dismantled, and ensuring construction safety.
[0006] As preferred, the ridge safety cable is higher than the roof height at the ridge end.
[0007] As preferred, the eave safety cable is higher than the roof height at the eave end.
[0008] As preferred, the fixed column is located outside the area to be dismantled, and the eave safety lock and the ridge safety lock both cover the entire range between the two sides of the area to be dismantled.
[0009] As preferred, a protective shed is arranged above the roof area to be dismantled, and the fixed column, the ridge safety cable, the eave safety cable and the movable safety cable are all arranged inside the protective shed.
[0010] As preferred, the protective shed comprises a roof truss and a film covering the surface of the roof truss, the outermost roof truss foot is supported on a corbel, and the fixed column is arranged inside the outermost roof truss,
[0011] As preferred, the ridge safety cable, the eave safety cable and the movable safety cable are all made of stainless steel cable.
[0012] The safety cable system in the utility model ensures the safety of the construction personnel, allows the construction personnel to flexibly work in the entire area to be dismantled, and ensures construction safety. BRIEF DESCRIPTION OF DRAWINGS
