Description

Technical Field

[0001] This utility model relates to a temporary guardrail for construction projects. Background Technology

[0002] During building construction, staircases serve as vital passageways connecting different floors, making their construction safety paramount. However, staircase construction often begins after the main building structure is completed. Before this, the staircase openings are open, posing a risk of falls. Therefore, temporary guardrails must be installed at the staircase openings before construction begins to ensure the safety of construction workers.

[0003] However, the temporary guardrails in the existing technology use steel pipe structures, which are connected by clamps. The bottom of the vertically set steel pipes needs to be inserted into the staircase, or connected by steel plates and bolts.

[0004] Both of the above connection methods require drilling holes in the surface of the staircase, which is troublesome to install and can easily cause the concrete to crack later.

[0005] Based on the above problems, we designed a temporary guardrail for construction projects that can be installed without drilling holes. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a temporary guardrail for construction projects that can be installed without drilling holes.

[0007] To solve the above problems, the present invention adopts the following technical solution:

[0008] A temporary guardrail for construction projects includes a hollow guardrail body. A groove is provided at the lower front end of the guardrail body, penetrating the guardrail body. A shaft is welded to the bottom front end of the guardrail body, through which a lower clamping assembly is rotatably mounted. A nut for positioning the lower clamping assembly is installed at the front end of the shaft. An upper clamping assembly is fitted onto the outside of the guardrail body, sliding along the guardrail body. A drive assembly is mounted on the guardrail body, driving the upper clamping assembly to slide along the groove. An installation assembly is rotatably mounted on the guardrail body, and a stop bar is installed through the installation assembly.

[0009] Preferably, the lower clamping assembly includes a bushing and a lower clamping plate welded to the outer wall of the bushing. An anti-slip strip is provided on the surface of the lower clamping plate to increase anti-slip properties. The bushing is rotatably sleeved on the shaft.

[0010] Preferably, the upper clamping assembly includes a sliding sleeve and an upper clamping plate welded to the outside of the sliding sleeve. A first anti-slip strip is provided at the bottom of the upper clamping plate to increase anti-slip properties. The sliding sleeve is slidably fitted onto the railing body. A sliding plate is welded inside the sliding sleeve. The sliding plate passes through the sliding groove. A threaded hole is provided in the middle of the sliding plate, and the drive assembly is engaged through the threaded hole.

[0011] Preferably, the drive assembly includes an end cap and a screw. The end cap is fixed to the top of the railing body. A bearing is installed in the middle of the end cap. The bearing is coaxial with the threaded hole. The screw cooperates with the bearing and the threaded hole. A force-bearing hole is passed through the outer wall of the screw near the upper end.

[0012] Preferably, the mounting assembly includes a mounting rod with a through groove in the middle. The railing body fits into the through groove, and a pin is fitted between the railing body and the mounting rod. The mounting rod rotates along the pin, and there is a rotational allowance between the through groove and the railing body. The stop bar is inserted into the mounting rod and fixed with screws.

[0013] The beneficial effects of this utility model are:

[0014] This product eliminates the need to drill holes in the surface of cast-in-place stairs or floor slabs during installation, saving the step of sealing the holes later. It also reduces a series of problems such as water leakage and cracks caused by drilling.

[0015] This product can be installed using a clamping method, which is highly efficient. It is also easy to remove and reuse.

[0016] This device has a simple structure and low cost, making it suitable for widespread use. Attached Figure Description
