Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel structure lap protection frame. Background Art

[0002] Steel structure is a structure made of steel materials and is one of the main types of building structures. The protective frame refers to a structure composed of facilities such as mounting rods and hangers used for the exterior walls of buildings. It can provide a safe working environment for construction workers and reduce wall damage and personal injuries caused by construction. During the construction of the protective frame, each joint must be riveted with screws, which involves a large workload and is prone to errors. If a screw is not riveted, it will pose a safety hazard.

[0003] In order to solve the above problems, a utility model patent with publication number CN219298847U discloses a construction protection frame. By setting up brackets and planks, the entire protection frame only has two adjusting screws on each plank. When building the protection frame, you only need to tighten the adjusting screws. Fewer screws need to be tightened during construction. Because of the setting of the middle piece, cross-connector and vertical pipe, the middle piece connects the cross-connector and the vertical pipe. No screws are needed during the connection process, and the efficiency of building the protection frame is higher.

[0004] In the process of building the protective frame, because the protective frame is made of a large number of steel pipes, and the vertical angle of the protective frame is required to be high when the steel pipes are spliced ​​and built, if the construction workers are skewed when splicing the cross bar, it is easy to cause the protective frame to become unstable, reducing the protective effect, and it is more laborious to install the cross bar. Multiple construction workers are required to lift the cross bar on the vertical pole to a certain height so that the cross bar is perpendicular to the vertical pole and then install the cross bar, which is time-consuming and laborious, and it is not convenient to adjust the height of the cross bar in the vertical pole, which is inconvenient and reduces the installation efficiency. The cross bar is difficult to disassemble during assembly and disassembly, and is usually fixed with multiple screws, so that multiple screws need to be screwed during disassembly, which is more troublesome, thereby extending the installation time and causing delays in the construction progress.

[0031] A cross bar 13 is provided at the top of the arc-shaped plate 4, and one end of the cross bar 13 is fixedly connected with a plug-in rod 14, which cooperates with the columnar groove 18. A mounting sleeve 15 is provided on the right side of the outside of the cross bar 13, which is threadedly connected with the first thread groove 16. A first thread groove 16 is provided on the left side of the outside of the cross bar 13 to facilitate the installation and connection of the mounting sleeve 15.

A columnar groove 18 is provided inside the left side of the cross bar 13 to facilitate the insertion of the plug-in rod 14. A plurality of card slots 19 are provided on the left side of the vertical rod 1 to facilitate the flexible engagement of the card rod 22. A fixed shell 20 is fixedly connected to the right side of the slider 3. The fixed shell The inner side of 20 is slidably connected to a limit block 21, and a clamping rod 22 is fixedly connected to the middle part of the limit block 21 to limit the position where the clamping rod 22 is pulled out. A spring 23 is fixedly connected to the left side of the limit block 21 to increase the rebound effect of the clamping rod 22. A second thread groove 24 is provided on the outer left side of the clamping rod 22, and a nut 25 is threadedly connected to the outer side of the second thread groove 24 to enhance the fixing effect of the clamping rod 22 after it is inserted.

The other end of the connecting rod 8 is rotatably connected to the left and right sides of the bottom end of the handle 6 to facilitate the connecting rod 8 to push the handle 6.

[0032] Working principle: When in use, first unscrew the nut 25 to loosen the clamping rod 22, and then pull open the clamping rod 22 so that the clamping rod 22 is in contact with the corresponding clamping groove 19. The clamping rod 22 drives the limit block 21 to drive the spring 23 to generate an elastic force that is squeezed, and then move the slider 3. According to the position where the cross bar 13 needs to be installed in the vertical rod 1, the position of the slider 3 is adjusted so that the slider 3 drives the arc plate 4 to drive the clamping plate 5 to move. After moving to the required position, release the clamping rod 22. Under the rebound action of the spring 23, the clamping rod 22 is pushed to engage with the corresponding clamping groove 19, and then the nut 25 is screwed to fix it. After the engagement, the locking rod 22 is fixed, and then the handle 6 is pressed downward, so that the handle 6 drives the clamping plate 5 to rotate and open at the front side of the slider 3. When the handle 6 is pressed downward, the rotating rod 7 and the connecting rod 8 are driven to fold and rotate, so that the connecting rod 8 drives the sliding column 10 to slide on the inner side of the rotating tube 9, thereby pressing down on the spring 11, so that the spring 11 generates elastic force, and then the cross bar 13 is placed in the cavity formed by the arc plate 4 and the clamping plate 5. The handle 6 is released, so that the handle 6 is pushed up by the rebound of the two springs 11, and the clamping plate 5 is reset, and the cross bar 13 is moved in multiple The cross bar 13 is clamped by the anti-slip strip 12, and then the bolt 26 is inserted into the middle of the top of the cross bar 13, and the fixing sleeve threadedly connected to the bolt 26 on the outside is screwed to fix the cross bar 13, thereby enhancing the verticality of the angle between the cross bar 13 and the vertical bar 1 when overlapping, reducing the instability of the protective frame caused by insufficient vertical angle, and facilitating the flexible movement of the height position of the cross bar 13 when the cross bar 13 is at a vertical angle to the vertical bar 1, saving time and effort, being more convenient, thereby improving the installation efficiency, and then when the two cross bars 13 are spliced, the plug-in rod 14 in the second cross bar 13 is inserted into the first cross bar 13 The mounting sleeve 15 in the second cross bar 13 is slid inside the columnar groove 18, so that when the mounting sleeve 15 moves to the shrink sleeve 17 in the first cross bar 13, the shrink sleeve 17 is squeezed by utilizing the closing effect of the tapered tail of the mounting sleeve 15, so that the shrink sleeve 17 squeezes the plug-in rod 14, and then the mounting sleeve 15 is rotated to make the mounting sleeve 15 threadedly connected with the first threaded groove 16, and the mounting sleeve 15 is squeezed and fixed to the shrink sleeve 17, which facilitates the splicing and disassembly of the cross bar 13, reduces the usage rate of screws during splicing and disassembly, and does not need to screw multiple screws for disassembly and splicing, which is more convenient, thereby shortening the installation time.
