Far-field protective structure dismantling flying stones

Abstract

The invention discloses a far-field protective structure dismantling flying stones. The structure comprises a steel tube rack, a bottom rod, an oblique rod, a cross rod and a buckling device. The right side edge of the steel tube rack fixes a grass curtain through the buckling device, a locking device is arranged on the inner side edge of the buckling device, and the locking device comprises a spring groove formed in the inner side wall of the buckling device; a locking spring is arranged in the spring groove, the outer side end of the locking spring is fixedly connected to a slide block, the slide block is located in the spring groove and can slide in the spring groove, the outer side end of the slide block is fixedly connected to a supporting rod, the outer side end of the supporting rod is fixedly connected to a locking head, a ball groove is formed in the side edge of the locking head, and a ball is arranged in the ball groove. A main body of the structure is in a form of a steel tube with the grass curtain, so that the stress capacity is strong, the cost is low, and the structure has popularizing and using value.

Description

technical field [0001] The invention relates to the field of steel frame structures, in particular to a far-body protection structure for removing blasting flying stones. Background technique [0002] With the development of my country's economy and technology, in order to eliminate backward production capacity, promote the transformation of industrial structure, beautify the urban landscape, and enhance the image of the city, some backward buildings and structures are blasted and demolished. The surrounding environment is complex and there are many buildings and structures that need to be protected. Recently, in order to further avoid the flying rocks generated during demolition and blasting from causing personal injury to surrounding personnel and damage to structures, it is necessary to set up a steel pipe bent protective structure between the building to be demolished and the protected building during blasting to control the impact of blasting flying rocks. Destruction of ...

AI Technical Summary

Problems solved by technology

[0003] The current blasting protection measures are relatively simple, such as the domestic patent 201521033273.2, the protection structure proposed by it is only a sponge layer sandwiched between the fixed net and the protective net. This protective measure has no support and its force-bearing capacity is weak. In actual use, it is easy to damage and poses a threat to the safety of surrounding buildings and personnel

Another example is the protective measures proposed in the domestic patent 201420155655.1. This method is to use springs to connect adjacent stainless steel plates. This method itself has a high strength, but it is easy to fall over after being stressed, and it needs to be repaired in time. It is inconvenient to use, and stainless steel The cost is high, the cost of use is relatively high, and it is not suitable for promotion
