Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and more particularly to a conveniently installed and disassembled protective net structure and a construction method thereof. Background Art

[0002] During the construction process, it is necessary to install a safety net on the side of the scaffolding away from the building wall. The safety net consists of a rectangular frame and a metal mesh welded inside the rectangular frame. It mainly has the functions of edge protection, dust isolation and noise reduction. It is an indispensable protective device in construction projects. The convenience and stability of its installation and disassembly directly affect the construction efficiency and safety.

[0003] Traditional methods of installing protective nets typically require drilling holes and securing them with bolts. This is not only cumbersome, time-consuming, and labor-intensive, but can also easily damage the net, shortening its service life. Furthermore, traditional net structures have limited support and adjustment capabilities, making them difficult to adapt to varying sizes and heights. Adjustment and fixation are also challenging for nets of varying widths, resulting in low construction efficiency and difficulties ensuring effective protection stability and safety.

[0004] Therefore, a protective net structure and a construction method thereof are proposed, which can be easily installed and disassembled, does not require holes to be drilled in the protective net, and has stable and adjustable support, in order to solve the problems existing in the prior art. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a convenient installation and removal of a protective net structure and a construction method thereof to solve the problems raised in the above-mentioned background technology.

[0007] By fixing each fixing component on the corresponding scaffolding steel pipe, and then inserting the four corners of the protective net frame into the corresponding slots, the supporting component is adjusted so that the bottom of the supporting component is pressed against the second beam, thereby supporting the rear side of the protective net, and finally, by locking each clamping component, the four corners of the protective net frame are clamped and fixed, so that the protective net is installed on the scaffolding. The operation is convenient and quick, and when disassembling, only the fixing components need to be removed to quickly disassemble the protective net, thereby improving construction efficiency.

[0008] Preferably, four fixing frames are provided, and the four fixing frames are commonly connected to the screen frame.

[0009] Preferably, the two upper fixing frames are commonly connected to a first crossbeam, the two lower fixing frames are commonly connected to a second crossbeam, and a support assembly slidably connected to the second crossbeam is installed on the first crossbeam.

[0010] Preferably, each guide frame is equipped with a locking pin.

[0011] Preferably, the fixing frame includes a support plate, a side baffle and a front fixing plate, a side baffle is welded to one side of the support plate, a front fixing plate parallel to the support plate is welded to one side of the side baffle, and the top ends of the support plate, the side baffle and the front fixing plate are commonly connected to a top plate, the support plate, the side baffle, the front fixing plate and the top plate are commonly surrounded by a card slot, and a clamping assembly is installed on the front fixing plate.

[0012] Preferably, a first screw hole is formed on the front fixing plate, and guide holes are formed on both sides of the first screw hole.

[0013] Preferably, the clamping assembly includes a splint, a first shaft seat, a first screw, a first knob and a guide rod. The first shaft seat is installed on one side of the splint, the first shaft seat is connected to the first screw screwed to the first screw hole, the first knob is installed on the end of the first screw, and the two guide rods pass through the corresponding guide holes and are connected to the splint.

[0014] Preferably, the fixing assembly includes a fixing plate, a pressure plate, a screw and a locking button. The fixing plate is welded on the top plate. A pressure plate is hinged on the top of the fixing plate. A U-shaped groove is provided at the bottom of the pressure plate. A screw that is plugged into the U-shaped groove is installed on one side of the fixing plate, and a locking button for crimping the pressure plate is installed on the screw.

[0015] Preferably, the support assembly includes a support beam, a lifting adjustment groove, a sliding groove, a second shaft seat, a second screw and a second knob.

[0017] Technical effects and advantages of the present invention: The structure can be quickly fixed to the scaffolding steel pipe through the fixing components. During installation, you only need to insert the four corners of the mesh frame into the slots, adjust the support components, and then lock the clamping components to complete the installation. When disassembling, remove the fixing components to quickly complete the disassembly, greatly improving construction efficiency.

[0018] By fixing the screen frame by clamping at four corners, the traditional installation method of opening holes in the protective screen is avoided, which reduces damage to the protective screen and simplifies the installation process.

[0019] The height of the support beam can be adjusted by rotating the second knob through the support assembly, so that the bottom slide of the support beam cooperates with the second crossbeam to achieve stable support for the middle part of the protective net, thereby improving the supporting strength and safety of the protective net; the locking pins on the guide frame can adjust the distance between the fixed frames, which is convenient for adapting to protective nets of different widths and expanding the scope of application.

[0020] Through the cooperation of the fixing assembly, the pressure plate, screws and locking buttons, the scaffolding steel pipe can be quickly clamped and fixed, which is easy to operate and saves installation time. BRIEF DESCRIPTION OF THE DRAWINGS
