[0002] The racks used in building construction are the structures on which construction workers stand while working. If a worker slips and falls from a rack while working, they could end up on another rack or fall to the ground, potentially causing serious injury.

[0003] A Chinese patent with announcement number CN219431438U discloses a safety anti-fall device for building construction, including a receiving net bag located below a current loading rack and above a loading rack adjacent to the current loading rack. One end of the receiving net bag is detachably connected to a vertical frame, and the other end is connected to an end of the loading rack close to the outer wall of the house. The receiving net bag is in a suspended state, each of the horizontal bars is connected to a connecting node, and one end of the receiving net bag is provided with a plurality of hooks, each of the hooks is hooked to a connecting node to detachably connect the receiving net bag to the vertical frame.

[0004] While this device can provide safety protection for construction workers by providing catch nets, companies generally recycle catch nets to save costs, leading to constant disassembly and reassembly. Because the catch nets are flexible, when a large number of them are disassembled and stored, hooks and latches can penetrate the net holes, causing them to become tangled and cluttered. This makes it more difficult for workers to separate the individual catch nets when the device is used again, reducing their user experience. Summary of the Invention

[0022] The technical solution of the present utility model will be further described below in conjunction with the embodiments.

[0023] As shown in the figure, the safety anti-falling device for building construction described in the utility model includes a loading rack 1, a plurality of cross bars 2 fixed on the loading rack 1 and extending to be connected to the outer wall, a cross beam 3 crossing the cross bars 2, and a plurality of receiving net bags 4 connected to the cross bars 2 and the outer wall. A first reel 5 and a second reel 6 for rolling up the receiving net bags 4 are respectively provided on both sides.

[0024] The first reel 5 and the second reel 6 are respectively arranged on both sides of the receiving net bag 4 away from and close to the outer wall.

[0025] Clamps for gripping the crossbeam 3 are movably mounted at both ends of the first reel 5. The clamps comprise two arcuate clamping blocks 7, which are mounted and rotatably offset by pins and arranged in opposition to each other. The ends of the two clamping blocks 7 are secured by bolts 8. By placing the two clamping blocks, the crossbeam of the carrier is placed between the two clamping blocks, which are then fixed in place by bolts, thereby securing one end of the receiving net to the carrier.

[0026] The end of the first reel 5 is rotatably connected to a connecting plate 9 fixed on the clamping jaw. A first spring rod 10 is provided at the central axis of one end of the first reel 5 , and the telescopic end of the first spring rod 10 is plugged into the connecting plate 9 .

[0027] One side of the connecting plate 9 close to the first spring rod 10 is evenly provided with annular first slots 11 around the central axis of the first spring rod 10 , and the telescopic end of the first spring rod 10 is fixedly mounted with a first protrusion 12 that is plugged into the first slot 11 .

[0028] The two ends of the second reel 6 are rotatably mounted with a rotating base 13. Slots 14 are provided at the bottom of the rotating base 13 at positions corresponding to the crossbar 2. The rotating base 13 and the crossbar 2 are connected by pins 15 passing through the slots 14. The rotation of the rotating base can drive the pins to rotate. After finding the appropriate angle, the rotating base is then plugged into the crossbar and fixed. The pins are used to fix the rotating base to the exterior wall, thereby fixing one side of the device to the exterior wall. However, if the rotating base cannot rotate, then the device will be greatly limited in fixing to the crossbar.

[0029] A second spring rod 16 is provided at the central axis of one end of the second reel 6. The telescopic end of the second spring rod 16 engages with the rotating base 13. Second retaining grooves 17 are evenly distributed annularly around the central axis of the second spring rod 16 on the side of the rotating base 13 near the second spring rod 16. A second protrusion 18 is fixedly mounted on the telescopic end of the second spring rod 16 to engage with the second retaining groove 17.

[0030] Nylon buckles 19 are provided between several adjacent receiving net bags 4, and the reels at adjacent positions are fixed by pin plugging, which can connect two adjacent receiving net bags 4. When construction workers accidentally fall between two receiving net bags 4, they can still be protected.

[0031] The working principle of the anti-falling device described in the utility model is as follows:

[0032] By setting two reels on both sides of the receiving net bag, the receiving net bag can be wound flatly on the surface of the reels, which can achieve the effect of orderly storing the receiving net bags. Specifically, when disassembling, the clamping claws are removed from the state of clamping the loading rack, and the pins are pulled out from the slots. At this time, the receiving net bag can be detached from the building support. The telescopic end of the spring rod is moved to disengage it from the slot, and then the two reels are continuously rotated to wrap the receiving net bag around the reels until the two reels contact each other. At this time, the telescopic end of the spring rod is inserted into the slot. Under the obstruction of the rotating seat and the clamping claws, the reels cannot rotate, and the receiving net bags are all wrapped around the reels. At this time, several receiving net bags are placed in a storage box. Adjacent receiving net bags are not likely to interfere with each other, thus completing the orderly storage of the receiving net bags. In addition, by setting a pin to fix the rotating seat and the cross bar together, one end of the receiving net bag can be fixed to the cross bar, wherein the pin and the rotating seat are slidably installed. This technical solution can also realize the separate storage of the pin by pulling out the pin, further avoiding interference between the pin and the receiving net bag.

[0033] During use, due to construction errors, the distance between the rack and the exterior wall can be inaccurate. To keep all the nets taut, the degree of rotation of the reels needs to be adjusted, thereby adjusting the length of the nets opened. Adjusting the reels' angles to keep the nets taut, inserting the protrusions into the slots secures the two reels relative to the rotating base and the clamping claws, respectively, preventing them from rotating. Furthermore, keeping the nets taut prevents them from swaying due to wind, which could interfere with construction workers.
