Description

Technical Field

[0001] This utility model belongs to the field of construction safety protection technology, specifically relating to a scaffolding construction safety fall prevention device. Background Technology

[0002] Scaffolding (or scaffolding) refers to various supports erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It is a common term in the construction industry, referring to the various supports used on construction sites for exterior walls, interior decoration, or areas with high ceilings where direct construction is not possible. When using scaffolding, fall protection nets are also installed underneath it to catch workers in case of accidental falls and reduce the occurrence of safety accidents.

[0003] Chinese patent CN216766857U discloses a safety device for preventing scaffolding erectors from falling from heights. This device utilizes a combination of side sliding rods, side sliding blocks, movable sliding rods, and netting sliding blocks. When a worker falls onto the safety net, the side sliding blocks move inwards, compressing a first spring. The netting sliding blocks on both sides then move inwards, compressing a second spring, causing the safety net to envelop the worker. This allows the first and second springs to absorb a significant amount of impact force, reducing the risk of the safety net breaking and improving the device's safety. However, in the aforementioned patent, the protective frame is installed on horizontal bars. However, during scaffolding erection, the horizontal or vertical bars are not yet continuously erected, preventing the early formation of a continuous horizontal structure suitable for attaching safety belts, posing a safety hazard and reducing the effectiveness of the scaffolding. This application proposes an alternative technical solution to address this problem. Utility Model Content

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The scaffolding construction safety fall prevention device shown includes a horizontal bar 1, a support bar 2, a footboard 3, a protective component, and a limiting component.

[0021] A first sliding fixing device 4, movably installed between the horizontal bar 1 and the support bar 2, constitutes the scaffold body. In this embodiment, there are four horizontal bars 1 and four support bars 2, arranged perpendicularly in two rows and two columns. Two perpendicularly intersecting horizontal bars 1 are connected to one support bar 2 through the first sliding fixing device 4. The first sliding fixing device 4 can be a disc fastener, which can flexibly adjust the mating position between the horizontal bar 1 and the support bar 2.

[0022] The tops of the two parallel horizontal bars 1 are fitted with scaffold boards 3 via a second sliding fixing device 5. The second sliding fixing device 5 may also be a disc fastener.

[0023] Two sleeves 6 are fixedly installed on the top of the scaffold board 3. Uprights 7 are inserted into the inside of the two sleeves 6, and safety ropes 8 are fixedly installed on the opposite side of the two uprights 7. Fixing pins 9 are inserted into the inside of each sleeve 6.

[0024] Both uprights 7 have through holes on their interiors and on the opposite side of the sleeve 6. Both sleeves 6 have insertion grooves on their interiors. That is, on the two opposite sidewalls of the sleeve 6 in the radial direction, one has a through hole and the other has an insertion groove. The fixing pin 9 passes through the through hole of the sleeve 6, then through the through hole of the upright 7, and then into the insertion groove of the sleeve 6, so as to fix and limit the upright 7.

[0025] In addition, there are six fixing pins 9, which are symmetrically distributed inside the two sleeves 6, and the outer side of the safety rope 8 is fixedly installed with an adjusting buckle 10.

[0026] With the protective components, while laying the scaffold boards 3, the safety rope 8 provides a device for operators to attach safety belts, ensuring the safety of scaffold erectors at an earlier stage, thereby improving the effectiveness of scaffold use.

[0027] In use, the horizontal bar 1 and the support bar 2 are adjusted and installed using the first sliding fixing device 4. Then, the scaffold board 3 is adjusted and fixed to the horizontal bar 1 using the second sliding fixing device 5. Next, the upright 7 is inserted into the sleeve 6 and fixed inside the sleeve 6 using the fixing pin 9. Then, the safety rope 8 is fixed between the two uprights 7 using the adjusting buckle 10 to form a passage. Then, the operator fastens the safety belt to the safety rope 8, thereby ensuring the safety of the scaffold erecting personnel.

[0028] The limiting assembly includes L-shaped mounting brackets 11 that are fixedly installed on both sides of the sleeve 6. Compression springs 12 are fixedly installed on opposite sides of the two L-shaped mounting brackets 11. Limiting plates 13 are fixedly installed on opposite sides of the two compression springs 12. The interior of the two sets of L-shaped mounting brackets 11 is provided with first sliding grooves. The limiting plates 13 are slidably connected to the L-shaped mounting brackets 11 through the first sliding grooves.

[0029] Each of the two limiting plates 13 has a clamping plate 14 fixedly installed on one side opposite to the other. A ball bearing is rolled on the bottom of the clamping plate 14. A second sliding groove is opened at the bottom of the inner wall of the sleeve 6, and the ball bearing is slidably connected to the sleeve 6 through the second sliding groove, which provides guidance for the movement of the clamping plate 14 and makes the movement of the clamping plate 14 more convenient.

[0030] In addition, through holes are provided on both sides of the two sleeves 6, and the clamping plate 14 extends into the inside of the sleeve 6 through the through holes to facilitate the initial positioning of the upright 7 inserted into the sleeve 6, so as to facilitate the fixed installation of the upright 7. A connecting plate 15 is fixedly installed at the bottom of the two limiting plates 13, and a handle 16 is fixedly installed at the bottom of the two connecting plates 15.

[0031] The limiting component facilitates the initial limiting of the upright 7, fixing the upright 7 inside the sleeve 6, improving the stability of the upright 7 installation, and further enhancing the safety of scaffolding use.

[0032] In use, by pulling the handle 16, the two limiting plates 13 on both sides of the sleeve 6 are moved in opposite directions, so that the clamping plate 14 moves synchronously and the compression spring 12 is compressed. Then, the upright 7 is inserted into the sleeve 6. Then, the handle 16 is released, so that the compression spring 12 is reset and the two clamping plates 14 are moved closer together. The clamping part of the clamping plate 14 initially limits the upright 7, which facilitates the fixed installation of the upright 7.

[0033] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
