[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] refer to Figure 1-3 A steel mesh scaffolding connector with an upper support and lower hook structure includes a connecting body 1, an upper support component 2, a lower hook component 4, and a connecting component 5. The connecting body 1 is the core load-bearing frame of the connector, used to integrate the upper support component 2, the lower hook component 4, and the connecting component 5, ensuring that the various structures work together to achieve a stable connection between the steel mesh 3 and the scaffolding. The upper support component 2 is located on the top of one side of the connecting body 1, and supports the steel mesh 3. The upper support component 2 can support the weight of the steel mesh 3, providing a vertical support foundation for the steel mesh 3 and avoiding... As the steel mesh 3 falls downwards due to its own weight, the lower hook component 4 is correspondingly located at the bottom of one side of the connecting body 1. It can hook the top edge of the steel mesh 3 to form a vertical two-way constraint, further restricting the vertical displacement of the steel mesh 3. The lower hook component 4 can also be used to secure the inner walls of the top two ends of the steel mesh 3 to restrict the horizontal displacement of the steel mesh 3. The upper support component 2 and the lower hook component 4 can be staggered. The connecting component 5 is located on the side of the connecting body 1 away from the upper support component 2 and can be fixed with the horizontal or vertical poles of the scaffold, thereby achieving the fixation of the steel mesh 3 on the scaffold.

[0019] In some embodiments, the lower hook component 4 includes a hook plate, which is disposed at the bottom of one side of the connecting body 1. The hook plate can be integrally formed or welded to the bottom of one side of the connecting body 1.

[0020] The hook plate can be L-shaped, with its horizontal section extending towards the steel mesh 3 side and a length of 12-22mm to ensure effective hooking of the steel mesh 3 frame keel; the vertical section height can be 25-30mm to form sufficient hooking depth and prevent the steel mesh 3 from detaching from the hook plate when subjected to external vibration; at the same time, the inner side of the hook of the hook plate adopts an arc transition design (the transition radius can be 3-5mm), which reduces frictional damage with the steel mesh 3 keel and facilitates quick alignment with the keel during installation to complete the hooking, improving operational efficiency.

[0021] Example 1: In some embodiments, the connecting body 1 includes a connecting plate 11, a limiting hole, and an insert plate 13. The connecting plate 11 can be made of Q235 high-strength steel plate (thickness can be 8-10mm) to ensure sufficient load-bearing strength and deformation resistance. One side of the connecting plate 11 can be integrally stamped to form an upper support component 2 and a lower hook component 4, avoiding the risk of weld cracking that may exist in welded connections and ensuring the connection strength of the three components. The connecting component 5 is fixedly provided on the other side of the connecting plate 11. A limiting hole (diameter 10-12mm) is opened on the side of the connecting plate 11 near the upper support component 2. The insert plate 13 is inserted into the limiting hole. The thickness of the insert plate 13 is adapted to the limiting hole, and the length can be 50-60mm. The insert plate 13 can be a right-angled trapezoidal block. After the steel mesh 3 is installed, insert plate 13 is inserted into the limiting hole. The end of the insert plate 13 is attached to the side of the frame keel of the steel mesh 3 to form a lateral limit, which prevents the steel mesh 3 from being horizontally displaced due to external forces such as wind and vibration during construction, further restricting the horizontal movement of the steel mesh 3, thereby improving the stability of the steel mesh 3 on the scaffold.

[0022] In some embodiments, the upper support component 2 includes a support plate 21, which can be integrally formed or welded to the top of one side of the connecting body 1.

[0023] The support plate 21 can be L-shaped, with a horizontal section length of 20-25mm, which can stably support the steel mesh 3 frame keel with a width of 20-30mm. The bearing area matches the keel size, avoiding excessive local stress that could cause keel deformation. The vertical section height can be 15-12mm, forming an initial vertical barrier for the steel mesh 3 keel. In addition, the upper surface of the horizontal section of the support plate 21 can be provided with anti-slip texture, which increases the friction with the frame keel, further improving the support stability and preventing the steel mesh 3 from sliding or shifting on the support plate 21.

[0024] In some embodiments, the connecting member 5 includes a base plate 51, which is disposed on the side of the connecting plate 11 away from the upper support member 2; The top plate 52 is hinged to the bottom plate 51 on the side away from the upper support component 2, and forms a fastening area with the bottom plate 51. The connecting screw 53 passes through the connecting plate 11 and the top plate 52 on the side near the upper support component 2 in sequence, and the connecting screw 53 is screwed into the connecting plate 11. A connecting nut 54 is located at the bottom of the connecting screw 53 and is screwed into the connecting screw 53.

[0025] In some embodiments, to accommodate scaffolding members of different diameters, the connecting component 5 includes a base plate 51, a top plate 52, a connecting screw 53, and a connecting nut 54. The base plate 51 can be made of rectangular steel plate and can be fixed to the side of the connecting plate 11 away from the upper support component 2 by welding. A 2-3mm thick rubber anti-slip pad is attached to its surface to increase friction with the scaffolding members and prevent loosening after connection. The top plate 52 has the same dimensions as the base plate 51, and its side away from the upper support component 2 can be hinged to the base plate 51. It can rotate around the hinge, and after rotation, it forms a clamping mechanism with the base plate 51 for holding the scaffolding members. The fastening area of ​​the component can be adjusted by rotating the top plate 52 to accommodate scaffold horizontal or vertical poles with a diameter of 40-50mm. The connecting screw 53 can be an M10 high-strength screw, which passes through the connecting plate 11 and the top plate 52 on the side near the upper support component 2. The connecting plate 11 can have a pre-set internal threaded hole, so that the connecting screw 53 can be screwed into the connecting plate 11. The top plate 52 can have a waist-shaped hole with a diameter slightly larger than the diameter of the connecting screw 53 to facilitate adjustment during the rotation of the top plate 52. The connecting nut 54 can be an M10 hexagonal nut, located on the top of the connecting screw 53 and screwed into it. During installation, drive the top plate 52 towards the bottom plate 51 until the anti-slip pad is in close contact with the scaffold member, and then tighten the connecting nut 54 to lock the position, ensuring stable clamping force and achieving a firm fixation between the connecting component and the scaffold.

[0026] The specific working principle is as follows: During actual construction, the construction workers installed multiple connectors at the bottom of the location where the steel mesh 3 was to be installed on the scaffolding, according to the design requirements.

[0027] Specifically, the top plate 52 is rotated upwards around the hinge to open it, so that the upper surface of the bottom plate 51 is against one side of the scaffold horizontal or vertical pole. Then, the top plate 52 is rotated downwards around the hinge until its lower surface is against the other side of the scaffold horizontal or vertical pole. At this point, the fastening zone formed by the bottom plate 51 and the top plate 52 encloses the scaffold members. Next, the workers rotate the connecting bolt 53 and the connecting nut 54 in the opposite direction, gradually bringing the top plate 52 closer to the bottom plate 51. The rubber anti-slip pads on the bottom plate 51 and the top plate 52 will fit tightly against the scaffold members. When significant resistance is felt, the rotation of the connecting bolt 53 is stopped, and the connecting nut 54 is tightened with a wrench to lock the position of the connecting bolt 53, preventing it from loosening during subsequent use, thus completing the stable connection between the bottom connector and the scaffold.

[0028] After connecting multiple connectors at the bottom of the scaffold, the construction workers move the steel mesh 3 to the designated location and slowly place the frame joists of the steel mesh 3 onto multiple support plates 21, with the bottom of the frame joists inserted into the grooves between the support plates 21 and the connecting plates 11. At this time, the horizontal section of the support plate 21 bears the entire weight of the steel mesh 3, while the vertical section provides initial vertical restraint for the frame joists, preventing them from shifting in the vertical direction.

[0029] Subsequently, construction workers installed multiple connectors on the top of the scaffolding at the location where the steel mesh 3 would be installed, according to design requirements. During installation, the top of the frame keel was inserted into the groove formed by the lower hook component 4 and the connecting plate 11 in the top connector, and then the above steps were used to achieve a stable connection between the top connector and the scaffolding. The bottom of the steel mesh 3 frame keel hooks with the L-shaped hook plate of the lower hook component 4. The vertical section of the hook plate forms a downward constraint on the keel, preventing the steel mesh 3 from falling downwards, and together with the upper support component 2, forms a two-way vertical fixing structure of "upper support and lower hook", ensuring the stability of the steel mesh 3 in the vertical direction.

[0030] Finally, the construction workers align the insert plate 13 with the limiting hole on the connecting plate 11 and insert the insert plate 13 into the limiting hole, so that one end of the insert plate 13 fits tightly against the side of the steel mesh 3 frame keel. The insert plate 13 will generate a horizontal restraining force on the keel, effectively preventing the steel mesh 3 from shifting horizontally due to external forces during construction. This completes the overall fixing of the steel mesh 3 and the connector.

[0031] Example 2: refer to Figure 4 The difference between this embodiment and embodiment one is that the specific structure of the connecting body 1 and the connecting component 5 is different. The connecting body 1, the upper support component 2, and the lower hook component 4 adopt a split structure, which can realize the detachable replacement of the upper support component 2 and the lower hook component 4, thereby improving the versatility and maintenance convenience of the connecting parts.

[0032] The connecting body 1 includes a connecting pipe 14, a insertion slot 15, an insertion plate 16, an anti-detachment pin 17, and a connecting spring 12. The connecting pipe 14 can be made of seamless steel pipe. A connecting component 5 is fixedly installed on the side away from the upper support component 2, and an insertion slot 15 is opened laterally in the middle of the other side for inserting the insertion plate 16. The insertion plate 16 can be a rectangular steel plate with a thickness adapted to the insertion slot 15. An upper support component 2 and a lower hook component 4 are fixedly installed on the side away from the connecting pipe 14. To prevent the insertion plate 16 from falling out of the insertion slot 15, an anti-detachment pin 17 is provided. The anti-detachment pin 17 passes through the connecting pipe 14 and the insertion plate 16 in sequence, and a connecting spring 12 is provided at the bottom of the anti-detachment pin 17. The spring is engaged in the groove at the bottom of the anti-detachment pin 17 to form an axial limit and ensure the reliability of the connection between the insertion plate 16 and the connecting pipe 14.

[0033] If the upper support component 2 or the lower hook component 4 is damaged, only the connecting spring 12 needs to be removed and the anti-detachment pin 17 needs to be pulled out to replace the new plug plate 16. There is no need to replace the entire connecting body 1, thereby reducing maintenance costs. At the same time, by designing plug plates 16 of different sizes, such as adjusting the size and spacing of the upper support component 2 and the lower hook component 4, different specifications of steel mesh 3 can be adapted, thereby improving the versatility of the connectors.

[0034] In some embodiments, the upper support component 2 includes a first limiting plate 22 and a second limiting plate 23. The first limiting plate 22 and the second limiting plate 23 are both vertically disposed on the top of the plug-in plate 16 on the side away from the upper support component 2, and can be integrally formed or welded and fixed. The second limiting plate 23 is attached to the side of the connecting pipe 14 away from the upper support component 2. The height of the first limiting plate 22 can be 20-25mm and the width can be 30-35mm. It is fixed to the top edge of the plug-in plate 16. The height of the second limiting plate 23 can be 20-25mm and the width is the same as that of the first limiting plate 22. It is attached to the outer side of the connecting pipe 14. The first limiting plate 22, the second limiting plate 23 and the plug-in plate 16 together form a support area. The width of the support area can be 25-35mm, which can directly accommodate the frame keel of the steel mesh 3. Lateral limiting can be achieved without the need to set the plug-in plate 13, which can save the plug-in plate 13 insertion and removal steps and further simplify the installation process.

[0035] In some embodiments, the connecting component 5 may be a scaffolding buckle, which can be fixed to the connecting pipe 14 by bolts. The scaffolding buckle may adopt a general structure, including a fixed base, movable buckle claws and locking bolts. The structure of the scaffolding buckle and the fixed connection principle with the scaffolding are existing technologies and will not be described in detail here.

[0036] The specific working principle is as follows: First, the construction workers select the corresponding support area width of the plug plate 16 according to the specifications of the steel mesh frame keel to be installed. Align the plug plate 16 with the plug groove 15 on the connecting pipe 14, and slowly insert it into the plug groove 15 until the pin hole on the plug plate 16 is completely aligned with the pin hole on the connecting pipe 14.

[0037] Subsequently, the anti-detachment pin 17 is inserted through the pin hole on one side of the connecting pipe 14, and then passes through the pin hole on the plug plate 16 and the pin hole on the other side of the connecting pipe 14, so that the bottom of the anti-detachment pin 17 protrudes from the other side of the connecting pipe 14. Finally, the connecting snap ring 12 is aligned with the annular groove at the bottom of the anti-detachment pin 17, and the connecting snap ring pliers are used to snap the connecting snap ring 12 into the annular groove, completing the fixation of the plug plate 16 and the connecting pipe 14, preventing the plug plate 16 from falling out of the plug groove 15 during use. This completes the assembly of the connectors that are compatible with the specifications of the steel plate mesh 3 frame keel to be installed.

[0038] At the bottom of the location where the steel mesh 3 will be installed on the scaffolding, multiple connectors are installed using connecting components 5. After the connectors are connected at the bottom of the scaffolding, the construction workers move the steel mesh 3 to the designated location and slowly place the frame keel of the steel mesh 3 into the support area between the first limiting plate 22 and the second limiting plate 23. The first limiting plate 22 and the second limiting plate 23 will laterally limit the keel frame to prevent horizontal movement; at the same time, the plug-in plate 16 provides vertical support for the keel, initially ensuring the stability of the keel.

[0039] At the top of the location where the steel mesh 3 will be installed on the scaffolding, multiple connectors are installed using connecting components 5. During installation, the top of the frame keel is first inserted into the groove formed by the hook component 4 and the connecting plate 11 in the top connector. Then, the top connector is securely connected to the scaffolding using connecting components 5. The vertical section of the hook plate exerts a downward restraining force on the keel, preventing the steel mesh 3 from falling downwards. Together with the supporting function of the upper support component 2, it forms a two-way vertical fixing structure of "upper support and lower hook," ensuring the stability of the steel mesh 3 in the vertical direction. This completes the connection and fixing of the steel mesh 3 and the connectors.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
