Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a quick-detachable safety guardrail for building construction. Background Art

[0002] At present, during the construction process, safety guardrails are important equipment to ensure the safety of workers. However, traditional guardrails are often difficult to install and disassemble, which not only increases the time cost of construction, but also affects construction efficiency.

[0003] The authorization announcement number in the prior art is: CN218862295U, and the name is a quick-detachable safety guardrail for construction, which includes a construction base, a slot component, a fastener assembly, a column and a positioning mechanism to achieve rapid installation and removal of the safety protection mesh. The construction base serves as the basis of the entire guardrail, and is provided with a slot component that can cooperate with the fastener assembly to connect the column. The design of the fastener assembly makes the connection between the column and the slot component both firm and easy to disassemble. The column is used to support the safety protection mesh to ensure the stability and safety of the mesh at the construction site. The safety protection mesh and the construction base are connected. The connection between them is achieved through a positioning mechanism, which includes a cylindrical tenon and a positioning screw, which cooperate with the transverse long holes on the construction base to ensure the stability and accuracy of the mesh in the horizontal direction. The positioning screw is connected to the adjacent construction base through a positioning seat, further enhancing the stability of the overall structure. However, when this patent is in use, although the installation and disassembly of the guardrail is relatively convenient, the entire guardrail is located on one side of the column during installation, which makes it easy to tilt during installation, and the protective effect is poor. It needs to be fixed to the ground with bolts, making the installation more stable and more time-consuming.

[0004] The authorization announcement number in the prior art is: CN105804423B, and the name is a quick-detachable safety guardrail for construction, which includes a base, a column, a plug-in column and a protective net. The clever combination of components realizes a fast, simple and safe installation process. The guardrail is mainly composed of a base and a column. The column is connected to the base by plugging, which ensures the stability of the structure. The plug-in columns symmetrically designed on both sides of the column are provided with vertical slots. The slots are open on one side and the top surface, which are convenient for plugging with the vertical rods on both sides of the protective net. This design not only simplifies the installation steps, but also improves the installation efficiency. The horizontal plug plate fixed at the bottom of the column can be connected with the upper part of the base. The horizontal slots on one side and the top opening are plugged in to further enhance the stability of the entire guardrail. In addition, the base can be fixedly connected to the ground to ensure the safety and stability of the guardrail during use. The structural design of the entire guardrail is simple and clear, and the installation process is convenient and quick, which greatly reduces the construction risk of guardrail installers. At the same time, its standardized and modular design is also convenient for disassembly and reuse, effectively improving resource utilization. However, although this patent is easier to install, there is no positioning device when the bottom horizontal slot is plugged in, which causes the guardrail to be offset during installation, resulting in poor protection.

[0022] See also Figure 1-4 The quick-detachable safety guardrail for construction includes three bases 3, a bracket 1 is fixedly sleeved on the top of the base 3, a protective frame 2 is welded on one side of the bracket 1, two grooves 12 are provided inside the bracket 1, one end of the protective frame 2 is located inside the groove 12, and two pressing blocks 5 are slidably assembled inside the bracket 1, one side of the pressing block 5 is fixedly connected with a connecting rod 7 by screws, one side of the connecting rod 7 is fixedly connected with a top rod 8 by screws, and the internal sliding assembly of the bracket 1 is equipped with two limiting rods 14, one side of the limiting rod 14 is fixedly connected with a straight rod 10 by screws, and one side of the straight rod 10 is fixedly connected with a pull block 4 by screws. Through the setting of structures such as the protective frame 2 and the bracket 1, the bracket 1 is placed on the ground during installation, and one end of the protective frame 2 is inserted into the inside of the bracket 1, so that the pressing block 5 drives the top rod 8 to move through the connecting rod 7, and the limiting rod 14 will bounce into the inside of the protective frame 2 after losing its limiting effect, thereby fixing it, making installation more convenient.

[0023] See also Figure 4 The bottom of the three bases 3 are all provided with square grooves, and four lifting and lowering adjustable rollers 17 are installed inside the square grooves. Through the arrangement of the base 3 and the rollers 17 and other structures, the protective frame 2 needs to be moved after being disassembled, but its body is heavy and inconvenient to move. Therefore, four lifting and lowering rollers 17 are arranged at the bottom of the base 3. When in use, the rollers 17 are pulled out and moved by the rollers 17, making it more convenient to carry.

[0024] See also Figure 1-4 Two circular grooves 11 are provided inside the bracket 1, and the pressure block 5 is slidably connected inside the circular groove 11. A first spring 6 is commonly connected between the circular groove 11 and the pressure block 5.
