Abstract

This utility model relates to the technical field of construction safety protection equipment, and discloses a temporary construction guardrail with a buffer function, including a mounting base, a lower guardrail, a sliding rod, an upper guardrail, a hinge frame, a hinge rod, a buffer protection plate, and a buffer airbag. The lower guardrail is vertically fixed to the top of the mounting base, the sliding rod is vertically fixed to the top of the lower guardrail, and the upper guardrail is slidably sleeved on the outside of the sliding rod. Two hinge frames are respectively fixed to the side walls of the lower and upper guardrails, one end of each of the two hinge rods is hinged to a corresponding hinge frame, and the other end is hinged to the buffer protection plate. The buffer airbag is sleeved on the outside of the buffer protection plate. When subjected to external impact, the buffer protection plate achieves initial force relief through the swing of the hinge rod, and the multi-chamber honeycomb structure of the buffer airbag further absorbs impact energy through deformation, forming a dual buffering effect of "mechanical swing + airbag deformation", effectively improving the impact resistance and safety protection capability of the guardrail.

Description

Technical Field

[0001] This utility model relates to the technical field of construction safety protection equipment, specifically a temporary construction guardrail with a buffer function. Background Technology

[0002] During construction, temporary guardrails are crucial for ensuring safety in construction areas and separating work and non-work spaces. Existing temporary guardrails mostly employ rigid structural designs, primarily consisting of fixed railings and bases, with their core function limited to physical isolation and warning. However, in the complex environment of construction sites, accidental collisions with workers and falling building materials frequently occur. Because existing guardrails lack effective buffering and energy-absorbing structures, the impact force acts directly on the guardrail itself and the impacting object (or person), easily leading to deformation or even damage, reducing its reusability. Furthermore, the inability to effectively dissipate the impact force can cause injuries, failing to meet the high safety standards required on construction sites and posing significant safety hazards. Therefore, developing a temporary guardrail with buffering capabilities that can effectively absorb impact energy is key to improving the level of safety protection in construction.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a temporary construction guardrail with a buffer function, comprising: a mounting base; a lower railing, vertically fixed to the top of the mounting base; a sliding rod, vertically fixed to the top of the lower railing; an upper railing, slidably sleeved on the outside of the sliding rod; two hinge frames, respectively fixed to the side walls of the lower and upper railings; two hinge rods, one end of which is respectively hinged to the two hinge frames; a buffer protective plate, hinged to the other end of the two hinge rods; and a buffer airbag, sleeved on the outside of the buffer protective plate.

[0005] Preferably, the hinge frame is a U-shaped frame structure, and the hinge rod is rotatably connected to the two side walls of the U-shaped frame through a rotating shaft, and the axis of the rotating shaft is perpendicular to the axis of the sliding rod.

[0006] Preferably, the outer surface of the sliding rod is provided with a limiting rod, and the inner wall of the upper railing is provided with a limiting groove that matches the limiting rod.

[0007] Preferably, the buffer plate is an arc-shaped plate or a straight plate, and its outer surface is provided with buffer grooves, raised anti-slip textures or elastic buffer layers.

[0009] Preferably, the mounting base has at least two mounting holes, which are evenly spaced along the length of the mounting base, and the mounting holes are provided with internal threads or anti-slip washers that are compatible with expansion bolts.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the buffer protective plate swings through the double hinge rods to push the upper railing to lift and relieve force, and the multi-cavity honeycomb structure of the buffer airbag further absorbs the impact energy, realizing the dual buffering of "mechanical swing + airbag deformation".

[0017] Please see Figure 1-4 This utility model provides the following technical solution: a temporary construction guardrail with a buffer function, comprising:

[0018] Mounting bracket 1:

[0019] Material: Q235 steel plate (thickness ≥ 5mm), cut into rectangular plates (length × width ≥ 200 × 100mm);

[0020] Machining: Make 2-4 mounting holes (diameter φ12-φ16mm), tap M12-M16 internal threads in the holes, or embed rubber anti-slip washers.

[0021] Lower railing 2 and sliding rod 9:

[0022] Material: Galvanized round pipe (outer diameter φ40-φ60mm, wall thickness ≥3mm);

[0023] Connection: The sliding rod 9 is welded and fixed to the lower railing 2, with a coaxiality error ≤0.5mm;

[0024] Limiting rod: Weld 2-4 flat steel bars (10mm wide, 5mm thick) around the sliding rod 9, with the length covering the adjustment stroke of the upper railing 3.

[0025] Upper railing 3:

[0026] Material: Same as sliding rod 9, but the inner diameter is 2-4mm larger than the outer diameter of the sliding rod (to ensure sliding clearance);

[0027] Limiting groove: A through groove (depth ≥ 5mm, length ≥ 500mm) is milled out along the inner wall to fit the limiting rod.

[0028] Hinged frame 4 and hinge rod 5:

[0029] Hinged frame 4: The steel plate is cut into a U-shape (opening width ≥ hinge rod 5 diameter + 2mm) and welded to the side wall of the lower and upper railings 3;

[0030] Hinged rod 5: Φ12-Φ16mm round steel, with holes drilled at both ends (hole diameter Φ14-Φ18mm), and hinged to hinge frame 4 and buffer protection plate 6 through pins. The pin surface is lubricated with grease.

[0031] Buffer protection plate 6:

[0032] Material: Elastic rubber (Shore hardness 60-80A) or modified plastic;

[0033] Processing: Molded into an arc shape (curvature radius ≥ 200mm) or a straight plate (thickness ≥ 10mm), with an integrally formed buffer groove (depth 3-5mm) or raised anti-slip texture (height 2-4mm) on the outer surface, or a 5-10mm thick sponge buffer layer is attached.

[0034] 8 airbags:

[0035] Material: Tear-resistant rubber (thickness ≥ 2mm), hot-pressed multi-chamber honeycomb structure (single chamber size 20×20mm), with chambers connected by Φ5mm vent pipes;

[0036] Sealing: The inner surface is coated with silicone sealant, which is then bonded to the outer wall of the buffer protection plate 6 and cured at room temperature.

[0037] Assembly process

[0038] Basic connection: Weld the lower railing 2 vertically to the top of the mounting base 1, ensuring that the verticality error is ≤1°;

[0039] Sliding system assembly: Vertically weld the sliding rod 9 to the top of the lower railing 2, and fit it into the upper railing 3, ensuring that the limiting rod is embedded in the limiting groove;

[0040] Hinged system installation: Weld hinge frames 4 to the side walls of the lower and upper railings 3, and hinge the two ends of the hinge rod 5 to the hinge frames 4 and the buffer protection plate 6 respectively;

[0041] Buffer assembly installation: Fit the buffer airbag 8 onto the outside of the buffer protection plate 6 to complete the overall assembly.

[0042] In use: The guardrail is fixed to the edge of the construction area by passing M12-M16 expansion bolts through the mounting holes of the mounting base 1 (the concrete base needs to be drilled to a depth of ≥80mm); when subjected to external impact, the buffer protection plate 6 swings to dissipate the force through the hinge rod 5, and the buffer airbag 8 absorbs energy through the deformation of the honeycomb chamber, thus achieving double buffering.
