Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically a building construction scaffold that prevents falling. Background Technology

[0002] In the construction industry, working at heights is an extremely common part of the work. Whether it's erecting the main structure of a building, renovating the exterior walls, or installing and maintaining equipment, construction workers need to use specialized scaffolding as a support platform for these high-altitude operations. The structural stability, safety features, and ease of operation of the scaffolding directly affect the efficiency of high-altitude work and the safety of personnel, making it an indispensable core auxiliary equipment in the construction process. Among these, the ground-mounted, modular scaffolding, which allows construction workers to directly step on it for work, is widely used in low- and medium-altitude construction scenarios due to its flexible setup and wide adaptability, becoming the main working platform on-site.

[0003] Traditional construction scaffolds lack comprehensive fall protection structures. During construction, construction materials such as wrenches, bolts, cement blocks, and pipes can easily fall from the gaps in the footboards, the sides of the scaffold, or the bottom, creating a risk of falling objects from height. This can not only injure construction workers on the ground and damage surrounding construction equipment, but also cause safety accidents on the construction site and increase construction safety management costs. Summary of the Invention

[0049] Example

[0050] Please see Figures 1-8As shown, the present invention provides a technical solution: a construction scaffold for preventing falling objects, comprising: a support rod 1, including a connector 12 fixedly arranged on the support rod 1; a fall prevention mechanism, including a fall prevention net 201 arranged on the support rod 1 for preventing objects from falling during construction; a support component, including a foot pedal 301 arranged in the middle of the support rod 1 for providing support during construction; and a locking assembly for locking the assembled fall prevention mechanism.

[0051] It should be noted that the support rod 1 is a vertical load-bearing structure, and the connector 12 is fixedly connected to the support rod 1 at intervals, providing a locking point for the connector 202; the fall protection mechanism is detachably assembled on the connector 12 of the support rod 1, and the support component is horizontally erected in the middle of the fall protection mechanism. The locking assembly locks the spliced ​​fall protection mechanism, the diagonal tie rod 13, and the spliced ​​support rod 1. With the support rod 1 as the vertical support, the fall protection mechanism is built through the connector 12, and the support component is erected in the middle to form a working surface. The locking assembly locks each spliced ​​component, forming an integrated construction frame structure, determining the core components of the construction frame and the basic functions of each component, realizing modular combination, and ensuring the basic load-bearing and fall protection functions.

[0052] In this embodiment, specifically: the fall protection mechanism further includes: a connecting rod 202, both ends of which are snapped onto the connecting member 12, and the fall protection net 201 is arranged inside the connecting rod 202; a central shaft 203, which is rotatably connected to the connecting rod 202, and one end of the fall protection net 201 is fixedly arranged on the central shaft 203, and the fall protection net 201 is wound around the central shaft 203; a limiting groove 204, which is formed at one end of the central shaft 203 for limiting the central shaft 203; a bolt 205, which is threaded through and connected to the connecting rod 202, and the lower end of the bolt 205 is snapped onto the limiting groove 204; and a torsion spring 206, one end of which is fixedly arranged on the central shaft 203, and the other end of which is fixedly arranged on the connecting rod 202.

[0053] Pulling the anti-fall net 201 causes the central shaft 203 to rotate and twist the torsion spring 206. After the anti-fall net 201 is unfolded to the specified length, tightening the bolt 205 causes the lower end to engage with the limiting groove 204 to lock the central shaft 203, thus fixing the unfolded state of the anti-fall net 201. Loosening the bolt 205 causes the torsion spring 206 to return the torque, causing the central shaft 203 to reverse, thus realizing the automatic winding of the anti-fall net 201. This allows the anti-fall net 201 to be internally stored and adjustable in unfolding, preventing damage from external exposure, extending its service life, and ensuring precise fixing of the unfolded length of the anti-fall net 201. The storage operation is also convenient.

[0054] In this embodiment, specifically: the limiting groove 204 is provided with several sets.

[0055] It should also be understood that the limiting grooves 204 are evenly opened along the circumference of the end of the central shaft 203, and the size of each set of limiting grooves 204 matches the lower end of the bolt 205 to achieve locking of the central shaft 203 at different rotation angles.

[0056] In this embodiment, specifically, the free end of the anti-fall net 201 is T-shaped.

[0057] In addition, the free end of the anti-fall net 201 is a rigid T-shaped structure with a width greater than the opening width of the slot 207 and less than the inner cavity width of the slot 207, thus achieving a snap-fit ​​and preventing detachment. After the anti-fall net 201 is unfolded, the free end T-shaped structure is inserted along the opening of the slot 207 and snaps into the inner cavity. The size difference prevents the anti-fall net 201 from falling off the slot 207 under external force, thus achieving a firm snap-fit ​​of the free end of the anti-fall net 201, avoiding loosening and displacement of the anti-fall net 201, ensuring protective stability, and the snap-fit ​​operation is simple, improving the unfolding and fixing efficiency.

[0058] In this embodiment, the fall protection mechanism further includes a slot 207, which is through-cut and arranged on one side of the connecting rod 202, and the T-shaped structure of the free end of the fall protection net 201 is engaged with the slot 207.

[0059] It should be noted that the slot 207 is a through slot that passes through the side wall of the connecting rod 202. The slot opening is a trapezoidal structure that is narrow on the outside and wide on the inside. It engages with the T-shaped structure at the free end of the anti-fall net 201, and its opening position matches the unfolding direction of the anti-fall net 201.

[0060] In this embodiment, specifically: the support component further includes: a locking rod 302, which is fixedly arranged at both ends of the foot pedal 301 and used to limit the foot pedal 301; and a locking groove 303, which is formed on the connecting rod 202 and the locking rod 302 is locked in the locking groove 303.

[0061] Specifically, the locking rods 302 at both ends of the foot pedal 301 are aligned with the locking grooves 303 on the connecting rod 202, and the foot pedal 301 is pressed to make the locking rods 302 engage in the locking grooves 303, thereby achieving horizontal setting and limiting of the foot pedal 301 and preventing the foot pedal 301 from slipping.

[0062] In this embodiment, specifically: the connecting rod 202 is provided in several groups, namely A connecting rod 202 and B connecting rod 202, and the snap-fit ​​groove 303 is provided in several groups on the A connecting rod 202.

[0063] It should also be understood that the connecting rods 202 are divided into two types, A and B. Connecting rod A is a horizontal main connecting rod 202, with the snap-fit ​​groove 303 evenly opened along the length of the connecting rod 202. Connecting rod B is a longitudinal connecting rod 202, which is perpendicularly spliced ​​with connecting rod A to form a square protective frame. Connecting rod B does not have snap-fit ​​groove 303. Connecting rod A is snapped onto the connector 12 of the support rod 1 along the width direction of the construction frame, and multiple footboards 301 are erected through the snap-fit ​​groove 303. Connecting rod B is snapped onto the connector 12 along the length direction of the construction frame, and is perpendicularly spliced ​​with connecting rod A. Anti-fall nets 201 are arranged inside both connecting rods A and B to form all-round protection.

[0064] In this embodiment, the locking assembly specifically includes: a plug rod 401, which locks the connecting rod 202 spliced ​​on the connector 12; a limiting plate 402, which is rotatably connected to one end of the plug rod 401 to prevent the plug rod 401 from falling off; and a groove 403, which is formed and arranged at one end of the plug rod 401 to accommodate the limiting plate 402.

[0065] In addition, the insertion rod 401 passes through the connecting rod 202 and the through hole of the connector 12 to achieve initial engagement. The limiting plate 402 is rotated out of the groove 403 and rotated to a 90-degree vertical position. Its own weight prevents the insertion rod 401 from falling off and locks the connecting rod 202 and the connector 12. When disassembling, the limiting plate 402 is rotated back into the groove 403 and the insertion rod 401 is pulled out.

[0066] In this embodiment, specifically: the insertion rod 401 is inserted through the through hole opened between the connecting rod 202 and the connector 12.

[0067] In this embodiment, specifically: a foot pad 11 is inserted into the bottom of the support rod 1, a diagonal tie rod 13 is inserted between the connectors 12 on every two sets of support rods 1, and the diagonal tie rod 13 is limited by a locking assembly. The lower end of the support rod 1 has a square structure, and the upper end of the support rod 1 has a corresponding square groove for splicing multiple sets of support rods 1 and limiting them by a locking assembly.

[0068] Among them, the foot pad 11 is an anti-slip foot pad with anti-slip texture on the bottom and a plug groove on the top that matches the bottom of the support rod 1; the diagonal tie rod 13 is a metal load-bearing rod with both ends snapped together with the connector 12, and diagonally connects to the connector 12 of the adjacent support rod 1 to form a triangular structure; the square structure at the lower end of the support rod 1 is perfectly matched with the size of the square groove at the upper end, and the splicing is seamless.

[0069] Working principle or structural principle: In use, firstly, the A connecting rods 202 on both sides are snapped into the connectors 12 on the two sets of support rods 1. Then, the insert rod 401 is inserted into the through holes at both ends of the connector 12 and the A connecting rod 202. The limiting plate 402 is rotated. Through the eccentric connection between the limiting plate 402 and the insert rod 401, one side of the limiting plate 402 is made vertical by its own weight, thereby preventing the insert rod 401 from falling off and ensuring the stability of the splicing of the A connecting rod 202 and the support rod 1.

[0070] When every two sets of support rods 1 are spliced ​​together as one unit by connecting rod A 202, connecting rod B 202 is used to splice the two sets of support rods 1 that have been spliced ​​together by the above steps, so that the four sets of support rods 1 form a square support structure through connecting rod A 202 and connecting rod B 202. Then, a set of diagonal tie rods 13 are inserted into one side of the connector 12 on both sets of support rods 1 and limited by the insert rod 401, which further improves the overall stability of the support rods 1.

[0071] Then, the bolt 205 is turned and rotated. The bolt 205 moves upward through the threaded connection to the connecting rod 202. When the lower end of the bolt 205 disengages from the limiting groove 204, the anti-fall net 201 on the A connecting rod 202 is pulled. The anti-fall net 201 drives the central shaft 203 to rotate on the connecting rod 202 and twists the torsion spring 206. When the T-shaped structure at one end of the anti-fall net 201 is engaged in the slot 207 opened on the corresponding set of A connecting rods 202 at the bottom, the bolt 205 is turned in the opposite direction. When the bolt 205 is re-engaged in the corresponding limiting groove 204, the anti-fall net 201 is limited. Next, the locking rods 302 on both sides of the foot pedal 301 are passed through the mesh holes on the anti-fall net 201 and engaged in the locking groove 303. The setting of three sets of foot pedals 301 can provide support for construction personnel and materials, and the foot pedals 301 can simultaneously limit the extended anti-fall net 201.

[0072] Repeat the above steps when pulling the anti-fall net 201 on the B connecting rod 202. When pulling the anti-fall net 201 on the B connecting rod 202, the pulled-out anti-fall net 201 should pass around the bottom of the three sets of foot pedals 301 and be snapped into the slots 207 on the B connecting rod 202 which are diagonally set on the support rod 1. The anti-fall net 201 on the A connecting rod 202 protects the sides of the foot pedal 301. The anti-fall net 201 on the B connecting rod 202 protects the rear side and the bottom of the foot pedal 301, which can prevent items and construction personnel on the foot pedal 301 from falling and improve the safety of construction.

[0073] Furthermore, the bottom of the support rod 1 has a square structure, and multiple sets of support rods 1 can be spliced ​​together through the square groove at the upper end of the support rod 1 and limited by the insertion rod 401 passing through the through hole, so as to increase the construction support height of the support rod 1. At the same time, the bottom of the support rod 1 is provided with foot pads 11 to improve the support stability of the bottom of the support rod 1. The bottom of the foot pads 11 can also be provided with universal wheels with self-locking function (not shown in the figure) to facilitate the movement of the assembled support rod 1.
