[0002] In the process of residential building construction, the installation of guardrails is crucial. It not only ensures the safety of construction workers, but also effectively prevents non-construction workers from mistakenly entering the construction area. However, traditional guardrail fixing methods often have problems such as difficulty in installation and disassembly, poor stability, and inability to be reused.

[0003] Specifically, traditional fixing methods usually use methods such as welding or bolting. These methods require professional operation during the installation process and are time-consuming, which seriously affects the construction efficiency.

[0058] The device mainly includes a guardrail mechanism 100 and a fixing mechanism 200 .

[0059] Embodiments of the guardrail mechanism 100:

[0060] The guardrail mechanism 100 is composed of a middle secondary telescopic rod body 101, and the rod body can be telescoped to adjust the length as needed.

[0061] At both ends of the middle secondary telescopic rod 101, connecting shafts 102 extending downward are symmetrically arranged.

[0062] A side sleeve 103 is installed on the connecting shaft body 102, and the side sleeve 103 and the connecting shaft body 102 are rotationally matched to ensure that the two can rotate relative to each other but will not move in the axial direction.

[0063] Implementation of the fixing mechanism 200:

[0064] Two fixing mechanisms 200 are provided, which are respectively located at two ends of the guardrail mechanism 100 and fixedly connected to the side sleeve 103 .

[0065] Each fixing mechanism 200 is composed of a first action arm 201 and a second action arm 202 , and the middle parts of the first action arm 201 and the second action arm 202 are connected by rotational cooperation, so that the first action arm 201 and the second action arm 202 can rotate relative to each other.

[0066] A hole-shaped portion 203 is provided on the first action arm 201 , and a nut 204 is rotatably installed in the hole-shaped portion 203 .

[0067] An arc portion 205 is disposed at the end of the second action arm 202 , and a screw rod 206 is mounted on the arc portion 205 . The screw rod 206 passes through the hole portion 203 of the first action arm 201 and is threadedly engaged with the nut 204 .

[0068] A handle 207 is installed at the end of the screw rod 206 . The screw rod 206 can be driven to rotate by rotating the handle 207 , thereby adjusting the angle between the first action arm 201 and the second action arm 202 .

[0069] A first clamping plate 208 is installed at the other end of the first moving arm 201 , and a second clamping plate 209 is installed at the other end of the second moving arm 202 . The two clamping plates are used to clamp the longitudinal beams of the building.

[0070] In order to enhance the clamping effect and fixing stability, a first friction pad 212 is disposed on the inner side of the first clamping plate 208 , and a second friction pad 213 is disposed on the inner side of the second clamping plate 209 .

[0071] The first action arm 201 and the second action arm 202 are both L-shaped, and the lower parts of their ends are respectively provided with a first lower auxiliary plate 210 and a second lower auxiliary plate 211 , which are in contact with the longitudinal beams of the building, further enhancing the fixing effect.

[0072] Directions:

[0073] The user places the first clamping plate 208 and the second clamping plate 209 of the fixing mechanism 200 on both sides of the building longitudinal beam.

[0074] By rotating the handle 207, the screw rod 206 is driven to rotate, so that the angle between the first action arm 201 and the second action arm 202 becomes smaller, so that the first clamping plate 208 and the second clamping plate 209 clamp the longitudinal beam of the building.

[0075] When disassembly is required, the handle 207 is rotated in the opposite direction to make the screw rod 206 rotate in the opposite direction, thereby loosening the first clamping plate 208 and the second clamping plate 209, so that the fixing mechanism 200 can be easily disassembled from the longitudinal beam of the building.

[0076] When the utility model is implemented, the user first places the first clamping plate 208 and the second clamping plate 209 of the fixing mechanism 200 on both sides of the longitudinal beam of the building. This step needs to ensure that the two clamping plates are tightly fitted to the surface of the longitudinal beam so that the subsequent clamping operation can firmly fix the fixing mechanism 200 on the longitudinal beam.

[0077] Next, the user manually rotates the handle 207 to drive the screw 206 to rotate. As the screw 206 rotates, the angle between the first action arm 201 and the second action arm 202 gradually decreases due to the threaded fit between the screw 206 and the nut 204, and the rotation fit between the hole 203 on the first action arm 201 and the nut 204. During this process, the first clamping plate 208 and the second clamping plate 209 gradually apply pressure to the longitudinal beam of the building until the longitudinal beam is tightly clamped in the middle.

[0078] In order to ensure the firmness and stability of the clamping, the first and second friction pads 212 and 213 are respectively arranged on the inner sides of the first clamping plate 208 and the second clamping plate 209. These friction pads not only increase the friction between the clamping plate and the longitudinal beam, but also protect the surface of the longitudinal beam to prevent damage during the clamping process.

[0079] When the fixing mechanism 200 needs to be disassembled, the user only needs to rotate the handle 207 in the opposite direction to make the screw rod 206 rotate in the opposite direction. As the screw rod 206 rotates in the opposite direction, the angle between the first action arm 201 and the second action arm 202 gradually increases, so that the pressure of the first clamping plate 208 and the second clamping plate 209 on the longitudinal beam of the building gradually decreases until they are completely loosened. At this point, the user can easily remove the fixing mechanism 200 from the longitudinal beam of the building for subsequent moving or storage operations.

[0080] Detachability: The device is designed as a detachable structure, which makes the installation and disassembly process more convenient and quick, greatly improving the work efficiency. At the same time, the detachability is also convenient for transportation and storage;

[0081] Stability: By adopting a special clamping mechanism and friction pads, the device can be firmly fixed on the building's longitudinal beams, ensuring the stability and safety of the guardrail during use;

[0082] Adjustability: The screw and nut mechanism in the device allows the distance between the clamping plates to be adjusted as needed to accommodate building longitudinal beams of different widths and shapes, making it highly versatile;

[0083] Environmental protection: The detachable design reduces pollution to the environment and conforms to the concept of green building and sustainable development;

[0084] Improve work efficiency: The detachable design simplifies the installation and disassembly process, reduces workers' operation time and labor intensity, and thus improves work efficiency.

[0085] Enhanced safety: The stable fixing method effectively prevents the guardrail from shaking and falling off, reduces the occurrence of safety accidents, and protects the lives of workers;

[0086] Reduced costs: Reusable and easy-to-maintain features reduce material and repair costs;

[0087] Improved applicability: The adjustable design enables the device to be applied to building longitudinal beams of different specifications and shapes, thus expanding its application scope and market potential;

[0088] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
