Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of scaffolding protection devices, and in particular relates to a scaffolding gap protection device and its usage method. Background Technology
[0002] In the construction industry, scaffolding, as an important temporary support structure for high-altitude operations, is widely used in various stages such as main structure construction, facade decoration, and equipment installation. Scaffolding is typically erected along the perimeter of the building, inevitably creating gaps of a certain width between it and the main structure. These gaps mainly arise from factors such as the complex shape of the building structure, diverse facade variations, and the overlapping of different construction processes. According to current construction safety regulations, these gaps must be effectively sealed to prevent workers from falling and to prevent accidents caused by falling construction materials, tools, and other objects. Therefore, how to safely, reliably, and efficiently protect the gaps between scaffolding and the structure has always been one of the key technical issues in construction safety management.
[0003] Currently, in practical engineering, the sealing of the aforementioned gaps typically employs a "fixed component + safety net" approach. This involves pre-embedding connectors in the main structure or setting fixing points through subsequent installation of expansion bolts, and then fixing the safety net between these fixing points using wire binding or hanging methods to cover the gap area. However, this existing technology still has several shortcomings in practical application. Regarding the "fixed component + safety net" approach, firstly, the embedded components need to be laid out in advance during the main structure construction phase, or expansion bolts need to be installed later through drilling. This not only increases the construction process but also easily damages the structure itself, making the construction cumbersome and time-consuming. Secondly, the safety net relies mainly on binding or hanging methods for fixation, resulting in a relatively dispersed stress system and poor overall stability. Under impact loads, it is prone to local loosening or even failure, making it difficult to meet high-standard safety protection requirements. Furthermore, these fixed components and safety nets are usually difficult to reuse, resulting in significant losses after removal, leading to high construction costs and low resource utilization efficiency. Summary of the Invention

Detailed Implementation
[0021] In the following description, embodiments of the scaffold gap protection device and its usage method of the present invention will be described with reference to the accompanying drawings.
[0022] The embodiments described herein are specific implementations of the present invention, used to illustrate the concept of the invention, and are illustrative and exemplary, and should not be construed as limiting the implementation or scope of the invention. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.
[0023] The accompanying drawings in this specification are schematic diagrams to aid in illustrating the concept of the invention, and schematically show the shapes of the various parts and their interrelationships. Please note that, in order to clearly demonstrate the structure of the components in the embodiments of the invention, the drawings are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0024] The following combination Figures 1 to 12 This invention describes a scaffold gap protection device and its usage method according to an embodiment, which includes: The cantilever adapter 6 includes a connecting plate and two side plates, which are respectively connected to both sides of the connecting plate. The side plates are provided with a pin hole 61 and an adjustment hole 62. The pin hole 61 is a round hole, and the adjustment hole 62 is an arc-shaped structure. The pin hole 61 is located between the connecting plate and the adjustment hole 62. The upright connection device includes a clamp 1 and a clamp locking bolt 4. The clamp 1 is fixedly connected to the connecting plate of the cantilever pole connector. The clamp 1 includes a first clamp 1 and a second clamp 1. One side of the first clamp 1 and the second clamp 1 are connected by a hinge shaft 2, and the other side is connected by the clamp locking bolt 4. The scaffold upright 3 is fixed in the clamp 1 of the upright connection device. In a further preferred embodiment, such as... Figure 3 The diagram also includes a rubber pad 5, which is positioned between the clamp and the scaffold upright. The rubber pad eliminates the gap between the clamp and the scaffold upright, improving the stability of the connection between them. Figure 1 As shown, scaffold boards 15 are installed on the frame composed of scaffold uprights and scaffold horizontals, and construction workers carry out construction on the scaffold boards.
[0025] The cantilever pole has one end connected to the cantilever pole adapter 6 via a pin 7. After the support angle of the cantilever pole is adjusted, the cantilever pole and the cantilever pole adapter 6 are fixed using a limiter 8 installed in the adjustment hole 62. By setting the limiter in the adjustment hole, quick locking is achieved after the cantilever pole angle is adjusted, making the structure stable and reliable, avoiding the loosening problem existing in traditional binding methods, thereby improving the structural rigidity and safety of the overall protective device. Figure 1 and Figure 3 In a preferred embodiment shown, the cantilever includes a main cantilever 9 and a secondary cantilever 10; one end of the secondary cantilever 10 is inserted into one end of the main cantilever 9, and the main cantilever 9 and the secondary cantilever 10 are fixed by a positioning bolt 11. For example, the connecting ends of the main cantilever and the secondary cantilever are respectively provided with equally spaced through holes, and the positioning bolt is inserted into the through holes to connect and fix the main cantilever and the secondary cantilever. By designing the cantilever as an insertable telescopic structure of the main cantilever and the secondary cantilever, and fixing it with positioning bolts, the length of the cantilever is adjustable, thereby adapting to the gap width requirements in different construction scenarios, improving the versatility and reusability of the device. Figure 10 In one specific embodiment shown, the end of the main boom 9 away from the secondary boom 10 is provided with a connecting part 91. The connecting part 91 is provided with a through hole and a limiter insertion hole 92. The pin 7 is inserted into the pin hole 61 of the boom adapter 6 and the through hole of the main boom 9 respectively. The limiter 8 is a screw, which is inserted into the adjustment hole 62 of the boom adapter 6 and the limiter insertion hole 92 of the main boom 9 respectively.
[0026] A locking ring 12 is fixed to the other end of the cantilever pole; a steel cable 13 is installed inside the locking ring 12; and a safety net 14 is connected to the cantilever pole and the steel cable 13. By setting a locking ring at the far end of the cantilever pole and connecting it with the steel cable and safety net, a stable force-bearing system is formed, making the force on the safety net more concentrated and reasonable, effectively dispersing the impact load of falling objects, and improving the load-bearing capacity and impact resistance of the protection system.
[0027] In the scaffold gap protection device of the above embodiment, the cantilever is in an inclined position. When a falling object hits the safety net, the impact force is transmitted through the cantilever to the position connected to the cantilever adapter, which can easily cause the cantilever to rotate undesirably, and in more serious cases, may cause the safety net to fail. In order to avoid the problem of insufficient stability when using a limiter to fix the cantilever and the cantilever adapter, the inventors further improved the above embodiment by including a cantilever anti-reverse device 16. The cantilever anti-reverse device 16 includes a ratchet 162 and a ratchet tooth 165. The ratchet 162 is fixedly connected to the pin 7, and the ratchet tooth 165 is fixed to the side plate of the cantilever adapter 6. The cantilever can rotate unidirectionally relative to the cantilever adapter 6 through the cooperation of the ratchet 162 and the ratchet tooth 165.
[0028] In another embodiment, the inventor provides a different structure for the rod anti-reverse device 16. The rod anti-reverse device 16 includes a connecting seat 161, a ratchet 162, a return spring 164, and a ratchet tooth 165. The connecting seat 161 includes two side bosses 1611, each with a mounting groove 1612. The side bosses 1611 are fixedly connected to the side plate of the rod adapter 6. The ratchet 162 is fixedly connected to the pin 7 and is located between the two side bosses 1611. The ratchet tooth 165 and the return spring 164 are installed in the mounting groove 1612 of the side bosses 1611. One end of the return spring 164 abuts against the ratchet tooth 165, and the other end of the return spring 164 abuts against the connecting seat 161. Figure 11 and Figure 12 As shown, the ratchet 165 has a trapezoidal structure, which includes an inclined plane 1653. (Combined with...) Figure 7 As shown, ratchet 165 can be inserted into the ratchet and control the ratchet to rotate only in one direction. When the ratchet needs to be rotated, the meshing ratchet teeth are separated from the ratchet. For example, a pull rod hole is provided at the corresponding position of the connecting seat, and the ratchet teeth are moved by the pull rod connected to the ratchet teeth. In a preferred embodiment of the invention, two ratchet teeth are provided that are radially symmetrical with respect to the ratchet. The ratchet is positioned by the two ratchet teeth, so that the ratchet is subjected to force balance and the problem of tooth dislodgement is easily caused by single ratchet positioning is avoided. By setting a lifting rod anti-reverse device (ratchet and ratchet structure), the lifting rod can only rotate in one direction. When subjected to external force impact, it can effectively prevent the lifting rod from rotating in the opposite direction, avoid the safety net from loosening or even failing due to angle changes, and significantly improve the reliability of protection. By introducing a return spring and connecting seat structure into the anti-reverse device, the ratchet teeth can automatically reset and re-engage with the ratchet after the external force is released, thereby realizing the automatic locking function, reducing manual intervention, and improving the safety and stability of the device.
[0029] In the aforementioned scaffolding gap protection device, when it is necessary to separate the ratchet from the ratchet and rotate the ratchet, it is necessary to operate two independent ratchets separately to disengage them from the ratchet. A single person cannot operate the ratchet and rotate the ratchet simultaneously; at least two people are required, increasing the difficulty and cost of use. In a further preferred embodiment, a winding device 163 is also included. The winding device 163 includes a winding wheel 1631, which is mounted on the outside of the connecting seat 161. A pull rope connecting ring 1652 is provided at the end of the ratchet 165 away from the ratchet 162. A pull rope hole 1613 is provided on the connecting seat 161. One end of the pull rope 166 is connected to the winding wheel 1631, and the other end is connected to the pull rope connecting ring 1652. By rotating the winding wheel, the pull rope can simultaneously drive the ratchet to move and disengage from the ratchet, thereby enabling one-handed operation of the ratchet and one-handed operation of the rotating ratchet, achieving the purpose of single-person construction. In a further preferred embodiment, a pull rope connecting block 1633 is provided on the outer side of the winding reel 1631, and one end of the pull rope 166 is connected to the pull rope connecting block 1633 of the winding reel. The pull rope connecting block can prevent the stretched end from disengaging from the winding reel.
[0030] In a further preferred embodiment, such as Figure 11 and Figure 12 As shown, the end of the ratchet 165 furthest from the ratchet 162 has a spring mounting groove 1651. A pull rope connecting ring 1652 is positioned within the spring mounting groove 1651, and one end of the return spring 164 is also mounted within it. The inner diameter of the return spring 164 is larger than the length of the pull rope connecting ring 1652. Mounting the return spring within the spring mounting groove prevents displacement, thus providing a stable thrust to the center of the ratchet. Positioning the pull rope connecting ring within the spring mounting groove and placing it inside the return spring allows for the fixation of the tension end without affecting the return spring's function, enabling the tension to pull on the center of the ratchet. In short, by rationally arranging the return spring and pull rope connecting ring within the spring mounting groove of the ratchet, the return spring operates stably while effectively transmitting tension, thereby improving the mechanism's structural compactness and operational reliability.
[0031] In a further preferred embodiment of the scaffold gap protection device, the winding device 163 further includes an operating wheel 1632, which is fixed to the outside of the winding wheel 1631. The outer surface of the operating wheel 1632 is provided with anti-slip protrusions, and the winding wheel is driven by the operating wheel.
[0032] This invention also provides a method for using a scaffold gap protection device, which is the same as the scaffold gap protection device described in the above embodiment. The method includes steps of fixing the upright connecting device to the scaffold upright 3, and adjusting the relative angle between the cantilever rod and the cantilever rod adapter 6 and fixing the position of the cantilever rod using a limiter 8. When the angle of the cantilever rod needs to be adjusted, firstly, the operating wheel 1632 and the winding wheel 1631 are rotated. The pull rope 166 pulls the ratchet 165 away from the ratchet 162. After the ratchet 165 disengages from the ratchet 162, the relative angle between the cantilever rod and the cantilever rod adapter 6 is readjusted. Then, the operating wheel 1632 is released, and the return spring 164 pushes the ratchet 165 into the ratchet 162.
[0033] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the invention to achieve the purpose of the invention.
