Description

Technical Field

[0001] The utility model relates to the technical field of clamp-type protective railing equipment, in particular to an adjustable clamp-type edge protective railing. Background Art

[0002] Usually, the steel pipe fastener edge protection used in the project needs to be regularly inspected and repaired due to problems with workers' installation and construction to ensure the safety of edge operations. Some steel pipes need to be painted for a long time to reduce corrosion due to long project time and high daily maintenance costs. The safety of various edge protections in the project is also one of the key focuses of construction projects and the focus of engineering safety technicians. It is extremely urgent to find a railing that can be recycled, has good durability and can achieve effective edge opening protection.

[0003] The edge opening adopts steel tube fastener type or tool type edge guardrail, and the horizontal and vertical bars are connected by steel tube fasteners. However, due to the weight of the steel tube fasteners themselves, eccentricity is easy to occur between the horizontal and vertical bars, which has a great impact on the force of the column. In addition, the edge bars need to be realized by drilling holes to embed expansion bolts or planting reinforcements, but the use of pre-embedded or planted reinforcements is very likely to cause a certain degree of damage to the beam-slab structure. For this reason, we propose an adjustable clamp-type edge guardrail. Utility Model Content

During the adjustment process, the lower clamp core 3 is inserted so that the bolt holes on the two are aligned, and the height of the lower clamp core 3 is adjusted to a suitable position, and the lower clamp core 3 is fixedly connected to the protective pole 2 by bolts 8.

[0022] The vertically adjustable clamp-type guardrail has the advantages of easy installation and disassembly, high safety and stability, and adjustability. It is suitable for edge protection of various projects such as floors and openings of different structural sizes. At the same time, it can greatly improve the installation efficiency of workers, has good economic effects, and effectively protects the safety of buildings and workers themselves.

[0023] In the above solution, the lower fixture core 3 is composed of a vertically arranged vertical plate and a horizontal plate to form an "L"-shaped structure.

In addition, the tool used for adjustment on the vertical pole is only a wrench, which is convenient and quick to install and disassemble. The vertical pole is effectively anti-tilted, with high safety and stability, and effectively ensures the safety of the project edge.

[0029] Working principle:

[0030] The specific operation steps of this adjustable clamp-type edge protection railing are as follows:

[0031] 1. The upper pole is integrated with the upper clamp, and is separated from the pole and insert of the lower clamp. Before installation, adjust the size of the clamp according to the size of the structural floor 9, assemble the upper and lower clamps, and fix them with bolts 8 (for example, if the floor size is 15cm, the upper and lower clamps can be adjusted to 20cm;

[0032] 2. The tool-type clamp is pre-installed on the structural floor 9. The clamp exceeds the size of the structural floor by 20 cm. At this time, the upper pressing plate 10 and the horizontal plate of the lower clamp insert 3 are parallel to each other and are arranged on the upper and lower sides of the structural floor 9;

[0033] 3. Place the rubber gasket 7 on the floor slab at the position corresponding to the bolt hole of the upper fixture, so that the rubber gasket 7 is located below the enlarged base at the bottom of the adjustable bolt 5;

[0034] 4. Install the nut 6 and the adjustable bolt 5, place the nut 6 above the bolt hole, and let the adjustable bolt 5 pass through the bolt hole to reach the predetermined position;

[0035] 5. Tighten the bolts. Use a tool wrench to tighten the adjustable bolts 5 on the structural floor 9. The enlarged base at the lower part of the adjustable bolts 5 corresponds to the rubber gasket 7. Use a tool wrench to tighten the bolts so that the rubber gasket 7 squeezes and fixes the structural floor 9 from the top. Under the action of the rubber gasket 7, the fixing effect of the equipment is improved;

[0036] 6. Continue to install other poles;

[0037] 7. Install the horizontal guardrail 1, which is fixed in the horizontal square through hole 11 by a latch as a protective mechanism;

[0038] And so on, until the edge protection railing is installed.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
