However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.
[0015] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.
[0016] Example 1
[0017] See Figure 1 and Figure 2As shown in this embodiment, a safety fall arrestor for high-rise building construction includes a left fall arrestor plate 1 and a right fall arrestor plate 2. A plurality of middle fall arrestor plates 3 are provided between the right fall arrestor plate 2 and the left fall arrestor plate 1. A row of first ear plates 4 arranged vertically at intervals is provided on the left and right sides of each middle fall arrestor plate 3. A row of second ear plates 5, matching the first ear plates, is provided on the right side of the left fall arrestor plate 1 and the left side of the right fall arrestor plate 2. A plurality of middle fall arrestor plates 5, each passing through the first ear plates, are provided between the left fall arrestor plate 1 and the adjacent middle fall arrestor plate 3. The left rope loop 6 of the second ear plate and the first ear plate; the right fall protection plate 2 and the adjacent middle fall protection plate 3 are provided with several right rope loops 7 that pass through the second ear plate and the first ear plate respectively; the two adjacent middle fall protection plates 3 are provided with several middle rope loops 8 that pass through the two first ear plates respectively; the left side of the left fall protection plate 1 is provided with an upper left fixed ear plate 9 arranged upwards and a lower left fixed ear plate 10 arranged downwards; the right side of the right fall protection plate 2 is provided with an upper right fixed ear plate 11 arranged upwards and a lower right fixed ear plate 12 arranged downwards.
[0018] Furthermore, the left fall arrestor plate 1, the right fall arrestor plate 2, and the middle fall arrestor plate 3 are each provided with a first hole 13, a second hole 14, two third holes 15, two fourth holes 16, and two fifth holes 17 that extend from front to back. The first hole and the second hole are arranged symmetrically from left to right and extend vertically. The two third holes are arranged symmetrically from top to bottom and are located to the left of the first hole. The two fourth holes are arranged symmetrically from top to bottom and are located between the first hole and the second hole. The two fifth holes are arranged symmetrically from top to bottom and are located to the right of the second hole.
[0019] Furthermore, the upper ends of the third hole 15, the fourth hole 16 and the fifth hole 17 arranged at the top are uniformly connected to the outside; the lower ends of the third hole 15, the fourth hole 16 and the fifth hole 17 arranged at the bottom are uniformly connected to the outside.
[0020] Furthermore, mounting holes 18 are provided on the upper left fixing ear plate 9, the lower left fixing ear plate 10, the upper right fixing ear plate 11, and the lower right fixing ear plate 12.
[0021] In this implementation plan, firstly, expansion bolts with hooks are driven into adjacent beams and columns. Then, the device is unfolded, and its two ends are connected to the expansion bolts with hooks to form a guardrail structure for fall protection. As bricks are gradually laid up below the device, the connecting lower left fixed ear plate 10 and lower right fixed ear plate 12 can be removed, and the device can be flipped up 180°. The new position after the flip is then connected using expansion bolts with hooks to the beams and columns. Finally, the expansion bolts with hooks are connected to the flipped-up lower left fixed ear plate 10 and lower right fixed ear plate 12, and this process is repeated.
[0022] The first hole 13, the second hole 14, the third hole 15, the fourth hole 16 and the fifth hole 17 are designed so that the left fall arrestor plate 1, the right fall arrestor plate 2 and the middle fall arrestor plate 3 can deform outward to a certain extent when subjected to end face impact, so as to dissipate the impact force and achieve the effect of collision prevention and impact resistance.
[0023] The present invention relates to a safety fall arrest device for high-rise building construction. This fall arrest device is easy to install, has a good blocking effect, good rebound, and can be retracted and extended. When retracted, it is small in size, easy to transport, and has complete overall functions and strong practicality.
