[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0032] like Figure 1-8 As shown, the first embodiment of the present invention is:

[0033] A climbing frame protection structure for building construction includes a climbing frame 1 formed by assembling a plurality of vertical poles 11 and a plurality of horizontal poles 12, wherein the horizontal poles 12 are mounted on a side of the vertical poles 11 away from the wall, a plurality of mounting holes 13 are formed between the top and bottom of the horizontal poles 12, and a plurality of protective net assemblies 2 are mounted between adjacent two horizontal poles 12;

[0034] The protective net assembly 2 includes a square frame 21, and a protective net plate 22 is installed on the side of the square frame 21 away from the wall. Mounting seats 23 are slidably installed inside the upper and lower sides of the square frame 21. Several fixing pins 24 that cooperate with the mounting holes 13 are installed on one side of the mounting seat 23. A pushing member 25 connected to the mounting seat 23 is installed on the side of the protective net plate 22 close to the wall. When the protective net assembly 2 is installed, the pushing member 25 pushes the fixing pins 24 on the upper and lower sides to insert into the mounting holes 13.

[0035] In this embodiment, the pushing member 25 includes a fixing seat 251 fixed on the protective mesh plate 22, and the fixing seat 251 is symmetrically and slidably connected to the two side walls with a first push rod 252, and one end of the first push rod 252 is inserted into the side of the square frame 21 and connected to the mounting seat 23, and the other end of the first push rod 252 is inserted into the inner cavity of the fixing seat 251 and is installed with a pushing block 253, and the pushing block 253 is provided with a first inclined surface, and the inner wall of the fixing seat 251 away from the protective mesh plate 22 is slidably connected with a pressure rod 254, and the end of the pressure rod 254 inserted into the fixing seat 251 is provided with a second inclined surface that cooperates with the pushing block 253, and a first spring 255 is connected between the pushing block 253 and the inner wall of the fixing seat 251. Through the structural design of the first push rod, the pushing block, the pressure rod and the inclined surface cooperation, convenient operation of the fixing pin is realized. Specifically, by pressing down or pulling up on the push rod, the construction worker leverages the interaction between the first and second inclined surfaces to easily drive the first push rod to slide, thereby inserting or withdrawing the fixing pin from the mounting hole. Compared to traditional, complex operations, this design greatly simplifies the process of connecting and disconnecting the protective net assembly from the climbing frame, reducing operator difficulty and improving installation and removal efficiency. Furthermore, the first spring provides a reset function for the push block, ensuring stable operation after repeated operations, thereby enhancing its reliability and service life.

[0036] In this embodiment, the pusher 25 also includes a stud bolt 256 and two nuts 257. The side walls of the fixing seat 251 and the pressure rod 254 are respectively provided with a first positioning hole and a second positioning hole that cooperate with the stud bolt 256. When the pressure rod 254 abuts against the bottom of the inner cavity of the fixing seat 251, the first positioning hole and the second positioning hole coincide with each other. When the pressure rod abuts against the bottom of the inner cavity of the fixing seat and the first positioning hole and the second positioning hole coincide with each other, the pressure rod is fixed by the stud bolt and the nut. This structure can effectively prevent the pressure rod from shifting or loosening due to external forces during use. That is, through the tightening action of the stud bolt and the nut, the pressure rod is firmly fixed to the fixing seat, ensuring that the relative positions of the various components of the pusher remain unchanged and maintaining the integrity of the pusher structure. Continuously providing reliable support for the stable installation of the protective net assembly, greatly enhancing the stability and reliability of the entire protective structure after installation, and reducing the risk of protection failure due to loose components.

[0037] The first push rod 252 is slidably connected to the inner wall of the first push rod 252, and the piston head 258 is connected to the side of the piston head 258, and the piston rod 259 is connected to the push block 253 at one end. When the pressure rod 254 is pressed down, the first push rod 252 is first pushed to slide, so that the fixing pin 24 is inserted into the mounting hole 13, and then the piston rod 259 is pushed to slide, so that the air bag 241 is inflated. This design provides a secondary fastening effect for the connection between the protective net assembly and the climbing frame. After the air bag is inflated, it tightly abuts against the inner wall of the mounting hole 13 to form an interference fit, which significantly enhances the stability and firmness of the connection, effectively eliminates the gap between the fixing pin and the mounting hole, and avoids shaking due to the existence of the gap under the influence of external vibration, wind, etc. Compared with the traditional connection method that simply relies on the insertion of fixed pins, this structure can effectively resist external forces such as vibration and wind generated during the construction process, prevent the protective net components from loosening or falling off, and greatly improve the safety of the climbing frame protection structure.

[0038] In this embodiment, a chute 2541 is formed on the sidewall of the pressure rod 254, which cooperates with the piston rod 259. The chute 2541 is located above and connected to the second inclined surface. The depth of the chute 2541 gradually decreases from the end closest to the second inclined surface to the end farther from the second inclined surface. When the pressure rod is pressed downward, the inclined surface first pushes the first push rod, causing the fixing pin to enter the mounting hole. The chute then contacts the piston rod. As the pressure rod continues to press downward, the chute gradually becomes shallower, pushing the piston rod to inflate the airbag. This design avoids the potential interference or operational errors caused by performing two actions simultaneously, making the entire installation process smoother and more precise, ensuring that the airbag is promptly inflated after the fixing pin is properly inserted, and further improving the reliability and stability of the protective net assembly installation.

[0039] In this embodiment, the mounting hole 13 includes a first mounting hole and a second mounting hole that are connected, and the inner diameter of the second mounting hole is larger than that of the first mounting hole. When the airbag 241 is inflated, the outer wall of the airbag 241 abuts the inner wall of the second mounting hole. When installing the protective net assembly, the fixing pin is first inserted into the second mounting hole. Due to its larger inner diameter, the positioning accuracy requirement for the fixing pin is lower. Construction workers do not need to spend a lot of effort on precise alignment and can quickly insert the fixing pin therein, greatly reducing the initial difficulty of installation and significantly improving the efficiency and convenience of installation. After the fixing pin is initially positioned in the second mounting hole, it continues to be inserted deeper into the first mounting hole. The first mounting hole with a smaller inner diameter can accurately limit the fixing pin and ensure that the fixing pin is accurately installed. When the airbag is inflated at the position of the second mounting hole, it tightly fits with the inner wall of the second mounting hole to form an interference fit. This not only further strengthens the connection between the fixing pin and the mounting hole, but also effectively fills the slight gap that may exist due to initial positioning, making the connection between the protective net assembly and the climbing frame more secure and reliable, and preventing the protective effect from being affected by loose connection.

[0040] In this embodiment, a fixed block 2510 is provided between the inner walls of the first push rod 252, and a sliding block 2511 is provided on the outer wall of the piston rod 259. The piston head 258, fixed block 2510, and sliding block 2511 are arranged in sequence. A second spring 2512 is sleeved on the outer wall of the piston rod 259, and the second spring 2512 is located between the sliding block 2511 and the fixed block 2510. The fixed block is provided on the inner wall of the first push rod, and the sliding block is provided on the outer wall of the piston rod, and cooperates with the second spring to provide a reset and limit function for the piston rod. When the airbag is inflated, the second spring can automatically reset the piston rod, preparing for the next installation operation, thereby improving the convenience and continuity of operation. At the same time, the provision of the fixed block and sliding block acts as a limiter for the sliding of the piston rod, ensuring that the piston rod moves within the specified travel range, preventing excessive sliding from causing overinflation or damage to the airbag, and ensuring the stability and reliability of the airbag inflation system.

[0041] In this embodiment, the inner wall of the first push rod 252 is provided with an abutment block 2513 that cooperates with the sliding block 2511, and in the process of the pressure rod 254 pushing the first push rod 252, the abutment block 2513 abuts against the sliding block 2511. In the process of the pressure rod pushing the first push rod to slide so that the fixing pin is inserted into the mounting hole, the abutment block and the sliding block cooperate with each other and can synchronously push the piston rod to slide, avoiding unnecessary sliding caused by the contact between the oblique surface of the piston rod and the pressure rod, ensuring that the process of inserting the fixing pin into the mounting hole is not interfered with, so that the fixing pin can be inserted into place smoothly and accurately, ensuring the accuracy and stability of the initial installation of the protective net assembly, and when the first push rod slides into place and the fixing pin is inserted, the piston rod enters the slide groove on the side wall of the pressure rod, and pushes the piston rod through the slide groove to perform the airbag inflation operation.

[0042] The specific installation process of this embodiment is as follows:

[0043] First, move the protective net assembly 2 between two adjacent cross bars 12, align the fixing pins 24 on the upper and lower side mounting seats 23 of the square frame 21 of the protective net assembly 2 with the mounting holes 13 on the cross bars 12, and prepare for installation.

[0044] The construction worker then presses down on the pressure rod 254 on the fixing seat 251. The second inclined surface of the pressure rod 254, inserted into one end of the fixing seat 251, cooperates with the first inclined surface of the push block 253. Under the force of the inclined surface, the push block 253 moves toward the inner wall of the fixing seat 251, driving the first push rod 252 connected to it to slide along the side wall of the fixing seat 251. The sliding of the first push rod 252 pushes the mounting seat 23 and the fixing pin 24 away from the protective mesh 22, allowing the fixing pin 24 to first be inserted into the second mounting hole of the mounting hole 13. Due to the larger inner diameter of the second mounting hole, the positioning accuracy requirement for the fixing pin 24 is lower, allowing for quick initial insertion of the fixing pin 24 and completing the pre-positioning.

[0045] Finally, the pressure rod 254 is pressed downward. Under the push of the first push rod 252, the fixing pin 24 is inserted deeply from the second mounting hole into the first mounting hole. The first mounting hole has a relatively small inner diameter, which allows for precise positioning of the fixing pin 24, ensuring that the fixing pin 24 is in the correct installation position, achieving precise initial fixation of the protective net assembly 2 to the climbing frame 1. When the pressure rod 254 is pressed downward to insert the fixing pin 24 into place, the sliding groove 2541 on the side wall of the pressure rod 254 contacts the piston rod 259. As the pressure rod 254 continues to be pressed downward (until it abuts the bottom of the inner cavity of the fixing seat 251), the depth of the sliding groove 2541 gradually decreases from the end closest to the second inclined surface to the end farther away from the second inclined surface. As a result, the pressure rod 254 pushes the piston rod 259 to slide toward the fixing pin 24. The piston rod 259 drives the piston head 258 to slide against the inner wall of the first push rod 252, forcing the gas in the first push rod 252 through the hollow connecting structure between the fixing pin 24, the mounting seat 23, and the first push rod 252, and into the airbag 241 sleeved on the outer wall of the fixing pin 24. The airbag 241 inflates and swells, and the outer wall of the airbag 241 located at the second mounting hole tightly abuts the inner wall of the second mounting hole, forming an interference fit, further enhancing the connection stability between the protective net assembly 2 and the climbing frame 1, completing the secondary tightening.

[0046] Finally, when the compression rod 254 is fully depressed until it contacts the bottom of the inner cavity of the fixing seat 251, the first positioning hole in the side wall of the fixing seat 251 coincides with the second positioning hole in the side wall of the compression rod 254. Stud bolts 256 are passed through the two holes and nuts 257 are tightened to rigidly connect the compression rod 254 to the fixing seat 251, preventing the compression rod 254 from accidentally loosening, thus completing the installation of the protective net assembly 2 on the climbing frame.

[0047] like Figure 1-10 As shown, the second embodiment of the present invention is:

[0048] The difference between this embodiment and the first embodiment is that;

[0049] In this embodiment, the left and right sides of the square frame 21 are hollow structures, and the left and right sides of the square frame 21 are slidably connected with plug-in strips 26. When the protective net assembly 2 is not installed, the plug-in strips 26 are flush with the side walls of the square frame 21, and a second push rod 2514 is slidably connected between the opposite side walls of the fixed seat 251. The second push rod 2514 is located below the first push rod 252, and the two ends of the second push rod 2514 are respectively connected to the two plug-in strips 26. The middle part of the second push rod 2514 is provided with a third inclined surface that cooperates with the second inclined surface on one side of the pressure rod 254. The outer wall of the second push rod 2514 is fixed with a connecting block 2515, and a third spring 2516 is connected between the connecting block and the inner wall of the fixed seat 251.

[0050] When installing the protective net assembly, the construction worker presses down on the pressure rod. The second inclined surface on one side of the pressure rod cooperates with the third inclined surface in the middle of the second push rod, which can accurately drive the second push rod to slide in a fixed direction. The two ends of the second push rod are connected to the plug-in strips on both sides, so that the plug-in strip on one side of the square frame extends and plugs out, and the plug-in strip on the other side is synchronously retracted to form a plug-in slot. The entire process is completed in one go, connecting multiple protective net assemblies into a whole. This design enhances the integrity and stability of the protective structure, allowing the protective net to better withstand external forces, preventing local damage or loosening that affects the overall protective effect, and by pressing the pressure rod downward to drive the second push rod to slide, thereby controlling the extension and contraction of the plug-in strips on both sides, so that the connection structure of adjacent protective net assemblies forms a unified pattern. All components are connected using the same plug-in principle, ensuring the consistency of the connection method of the entire protective structure, making it easier for construction workers to quickly master the installation method and reduce operational errors caused by differences in the connection structure.

[0051] In this embodiment, a through slot 2517 that cooperates with the pressure rod 254 is penetrated through the middle part of the second push rod 2514, and a third inclined surface is provided on one side of the through slot 2517. When the pressure rod is pressed down, the pressure rod can pass through the through slot and abut against the bottom of the fixing seat, thereby not affecting the fixation between the pressure rod and the fixing seat.

[0052] The specific installation process of this embodiment is as follows:

[0053] The installation process of this embodiment is the same as that of the first embodiment, except that:

[0054] During the downward movement of the pressure rod 254 (synchronized with the inflation of the airbag 241), the second inclined surface on one side of the pressure rod 254 cooperates with the third inclined surface in the middle portion of the second push rod 2514. As the pressure rod 254 is pressed downward, the second inclined surface pushes the third inclined surface, driving the second push rod 2514 to slide in one direction between the opposite side walls of the fixed seat 251. The plug-in strips 26 connected to both ends of the second push rod 2514 slide in the same direction, causing one side of the square frame 21 to retract to form a plug-in slot, while the plug-in strip 26 on the other side extends and inserts into the corresponding retracted plug-in slot of the adjacent protective net assembly 2. The newly formed plug-in slot awaits insertion of the plug-in strip 26 of the adjacent protective net assembly 2. In this way, multiple protective net assemblies 2 are plugged and fixed to each other to form an integrated protective structure, enhancing the integrity and stability of the entire protective structure.

[0055] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements.
