Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a horizontal bar for scaffolding. Background Technology

[0002] In the construction industry, disc-lock scaffolding is a commonly used support structure. It achieves a quick and stable connection between the uprights and horizontal bars through special connectors. However, traditional horizontal bars are exposed to the external environment for a long time, especially in humid or chemically-containing environments, which can easily lead to corrosion of the steel pipe surface and shorten its service life. Secondly, during use, friction between the horizontal bars and other components can cause surface wear, affecting the safety and stability of the structure.

[0003] To address this issue, this utility model proposes a horizontal bar for scaffolding. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a scaffolding horizontal bar to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a horizontal scaffolding pole, comprising: a pole body, the main body being cylindrical, a groove being formed on the pole body, a connecting groove being formed at the end of the pole body, a positioning groove being formed on the outer wall of the pole body, and a buckle groove being formed in the positioning groove, the buckle groove communicating with the groove; and a protective sleeve, installed in the positioning groove, the protective sleeve having a through groove, the through groove corresponding to the buckle groove.

[0007] Preferably, as described in any of the above embodiments, inclined grooves are provided on both sides of the groove.

[0008] Preferably, in any of the above solutions, the intersection between the connecting groove and the recess is a slope; the connecting groove is arc-shaped to match the scaffold uprights.

[0009] Preferably, the rod is made of an alloy material, as described in any of the above solutions.

[0010] Preferably, the protective sleeve is supported by a multi-layer composite material, including an anti-corrosion layer. The anti-corrosion layer is placed in the innermost layer of the protective sleeve and is used to directly contact the rod body to resist moisture, oxygen and other corrosive substances in the external environment.

[0011] Preferably, in any of the above embodiments, the protective sleeve further includes an anti-wear layer, which is connected to the anti-corrosion layer to protect the rod from external physical wear.

[0012] Preferably, as described in any of the above embodiments, the protective sleeve further includes a protective layer connected to the anti-abrasion layer. The protective layer is placed on the outermost layer of the protective sleeve to provide additional physical protection against external impacts or other forms of mechanical damage.

[0013] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0014] 1. The protective sleeve is made of multi-layer composite material, with the innermost layer being an anti-corrosion layer that directly contacts the pole body. This effectively isolates moisture, oxygen, and other corrosive substances from the external environment, significantly improving the pole body's corrosion resistance and extending its service life.

[0015] 2. An anti-wear layer is set outside the anti-corrosion layer to protect the pole from external physical wear. This design is particularly suitable for applications that require frequent movement or are subject to large friction forces, ensuring the integrity of the pole surface and enhancing the stability of the overall structure.

[0016] 3. The outermost protective layer provides additional physical protection against external impacts or other forms of mechanical damage. This not only improves the durability of the horizontal bar but also reduces the risk of damage caused by accidental collisions, ensuring the safety of the construction site.

[0017] 4. The connecting groove at the end of the pole is designed in an arc shape to match the scaffolding uprights, which increases the stability and reliability of the connection.

[0031] like Figures 1 to 10 As shown, a horizontal scaffolding pole includes a pole body 1 and a protective sleeve 2.

[0032] Furthermore, the main body of the rod 1 is cylindrical, a groove 11 is provided on the rod 1, a connecting groove 12 is provided at the end of the rod 1, a positioning groove is provided on the outer wall of the rod 1, and a buckle groove 13 is provided in the positioning groove, which is connected to the groove 11.

[0033] The groove 11 has inclined grooves on both sides, and the groove 11 is designed to engage with the disc buckle installed on the scaffold upright.

[0034] The intersection between the connecting groove and the recess 11 is an inclined surface;

[0035] The connecting groove 12 is arc-shaped and is used to match the scaffold upright, so that the pole 1 and the scaffold upright fit more closely.

[0036] The rod body 1 is made of alloy material.

[0037] Furthermore, the protective sleeve 2 is installed in the positioning groove, and the protective sleeve 2 is provided with a through groove 21, which corresponds to the position of the buckle groove 13;

[0038] The protective sleeve 2 has the same outer contour as the rod 1.

[0039] Specifically, the protective sleeve 2 is supported by a multi-layer composite material, including an anti-corrosion layer 201. The anti-corrosion layer 201 is placed in the innermost layer of the protective sleeve 2 and is used to directly contact the rod body 1 to resist moisture, oxygen and other corrosive substances in the external environment. The anti-corrosion layer 201 is made of epoxy resin and polyurethane composite. The epoxy resin has excellent chemical resistance and adhesion, and the polyurethane, in addition to excellent anti-corrosion performance, also provides good wear resistance. The composite of the two materials makes the anti-corrosion layer 201 have good anti-corrosion properties, ensuring that the rod body 1 is not easily corroded, thereby improving the service life of the rod body 1.

[0040] The protective sleeve 2 also includes an anti-wear layer 202, which is connected to the anti-corrosion layer 201 and is used to protect the rod body 1 from external physical wear. The anti-wear layer 202 is made of high-density polyethylene and fiberglass composite. The high-density polyethylene has excellent wear resistance and impact resistance, while the fiberglass is fiber reinforced plastic, which is known for its high strength and good wear resistance, and also has a certain degree of corrosion resistance. The composite of the two materials gives the anti-wear layer 202 good wear resistance, protects the anti-corrosion layer 201, and further increases the service life of the anti-corrosion layer 201.

[0041] The protective sleeve 2 also includes a protective layer 203, which is connected to the anti-wear layer 202. The protective layer 203 is placed on the outermost layer of the protective sleeve 2 to provide additional physical protection against external impacts or other forms of mechanical damage. The protective layer 203 is made of rubber and has good shock absorption and cushioning effects to absorb energy and reduce impact damage.

[0042] The protective sleeve 2 protects the pole 1 and increases its service life.
