Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel pile technology, and in particular to a high-strength corrosion-resistant fence steel pile. Background Technology
[0002] With the acceleration of urbanization and the growth in demand for infrastructure construction, fencing systems are increasingly widely used in homes, industries, and transportation. Traditional fence steel piles mostly adopt a rigid connection structure. However, when subjected to external impacts (such as vehicle collisions or vandalism), rigid steel piles are prone to deformation or breakage, resulting in high repair costs and affecting the overall stability of the fence. Furthermore, rigidly connected fence steel piles have poor seismic resistance and are prone to excessive internal structural stress due to vibration.
[0003] Therefore, it is necessary to provide a new high-strength, corrosion-resistant steel fence post to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a high-strength corrosion-resistant steel fence post.
[0005] The high-strength, corrosion-resistant steel fence posts provided by this utility model include:
[0006] Upper pile body, and
[0007] The lower column used to support the upper pile body;
[0008] The upper pile body and the lower column body are elastically connected, and a spiral elastic steel sheet is installed between the upper pile body and the lower column body;
[0009] The outer wall of the lower column has several evenly distributed spherical cavities, and each spherical cavity contains a rolling steel ball.
[0010] Preferably, one end of the spiral elastic steel sheet is fixedly connected to the lower column surface of the upper pile body, and the other end of the spiral elastic steel sheet is fixedly connected to the upper column surface of the lower column body.
[0011] Preferably, a spirally arranged spiral rubber strip is fixedly embedded in the upper wall of the spiral elastic steel sheet.
[0012] Preferably, one-third of the steel ball extends out of the spherical cavity and is positioned outside the lower column.
[0013] Preferably, an insert steel column is fixedly installed on the lower column surface of the upper pile body, and the insert steel column is inserted into the insertion cavity opened in the lower column body and slidably connected to the insertion cavity.
[0014] Preferably, the spiral elastic steel sheet is sleeved around the inserted steel column.
[0015] Preferably, the outer cylindrical surface of the upper pile body is fixedly equipped with multiple annularly distributed connecting lugs.
[0016] Preferably, an installation ball is fixedly installed on the top of the upper pile body.
[0017] Preferably, a fixed base is fixedly installed at the bottom of the lower column.
[0018] Preferably, both the upper pile and the lower column are coated with polyurethane coating.
[0019] Compared with related technologies, the high-strength corrosion-resistant steel fence piles provided by this utility model have the following beneficial effects:
[0020] When the upper pile is subjected to downward pressure, the inserted steel column slides along the insertion cavity. At this time, the spiral elastic steel sheet contracts, thus effectively reducing the high pressure on the fence steel pile and improving its compressive strength. Compared with traditional rigid connection steel piles, it can better cope with external impacts and reduce the risk of deformation and damage. When the external pressure on the upper pile is removed, the upper pile is reset under the elastic force of the spiral elastic steel sheet. Under dynamic load, the steel ball can play a certain role in energy dissipation and shock absorption. It can absorb and dissipate some seismic energy through rolling and small displacement, reduce the vibration response of the lower column, and improve the seismic resistance of the lower column.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0028] Please see Figures 1 to 4 This utility model provides a high-strength corrosion-resistant fence steel pile, which includes an upper pile body 1 and a lower column body 2 for supporting the upper pile body 1. The upper pile body 1 and the lower column body 2 constitute the fence steel pile structure.
[0029] In the embodiments of this utility model, please refer to Figures 1 to 4 The upper pile body 1 and the lower column body 2 are elastically connected. Specifically, a spiral elastic steel sheet 3 is installed between the upper pile body 1 and the lower column body 2. One end of the spiral elastic steel sheet 3 is fixedly connected to the lower column surface of the upper pile body 1, and the other end of the spiral elastic steel sheet 3 is fixedly connected to the upper column surface of the lower column body 2. An inserted steel column 11 is fixedly installed on the lower column surface of the upper pile body 1, and the inserted steel column 11 is inserted into the insertion cavity 2a opened in the lower column body 2 and is slidably connected to the insertion cavity 2a.
[0030] It should be noted that when the upper pile body 1 is subjected to downward pressure, the inserted steel column 11 slides along the insertion cavity 2a. At this time, the spiral elastic steel sheet 3 contracts, thus effectively reducing the strong pressure on the fence steel pile and improving the compressive strength of the fence steel pile. Compared with the traditional rigid connection steel pile, it can better cope with external impact and reduce the risk of deformation and damage. When the external pressure on the upper pile body 1 is removed, the upper pile body 1 is reset under the elastic force of the spiral elastic steel sheet 3.
[0031] Furthermore, the spiral elastic steel sheet 3 is sleeved around the inserted steel column 11, so that the spiral elastic steel sheet 3 effectively protects the inserted steel column 11, prevents the inserted steel column 11 from being worn during frequent sliding, and extends the service life of the inserted steel column 11.
[0032] Furthermore, a spiral rubber strip 31 is fixedly embedded in the upper wall of the spiral elastic steel sheet 3. Therefore, when the upper pile body 1 is subjected to pressure, causing the spiral elastic steel sheet 3 to compress and stick together, the spiral rubber strip 31 can alleviate the potential damage to the spiral elastic steel sheet 3 due to compression and sticking, and ensure the long-term stability of the elastic buffer function of the spiral elastic steel sheet 3.
[0033] In this design, a fixed base 7 is fixedly installed at the bottom of the lower column 2 to facilitate the fixed installation of the fence steel pile. Multiple annularly distributed connecting lugs 5 are fixedly installed on the outer column surface of the upper pile 1. The connecting lugs 5 facilitate the installation of crossbars on the fence steel pile. An installation ball 6 is fixedly installed at the top of the upper pile 1, which improves the aesthetics of the fence steel pile.
[0034] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The lower column 2 has several evenly distributed spherical cavities on its outer column wall. Each spherical cavity contains a rolling steel ball 4, and one-third of the steel ball 4 extends out of the spherical cavity and is placed on the outside of the lower column 2.
[0035] It should be noted that: because the lower column 2 is close to the ground, it is easily impacted by external objects. When the lower column 2 is impacted by external objects, the exposed steel ball 4 can reduce the impact force on the lower column 2, and the rolling steel ball 4 can drive the external objects to roll down along the lower column 2, further relieving pressure on the lower column 2, thereby greatly improving the strength of the fence steel pile.
[0036] In this embodiment, under dynamic loads (such as vehicle vibration or wind vibration when passing over the fence steel piles), the steel ball 4 can play a certain role in energy dissipation and vibration reduction. It can absorb and dissipate some seismic energy through rolling and small displacement, reduce the vibration response of the lower column 2, and improve the seismic resistance of the lower column 2.
[0037] When the lower column 2 needs to be partially embedded in the soil, the steel ball 4 allows for a small displacement between the lower column 2 and the surrounding soil, preventing the steel pile from tilting or breaking due to foundation settlement.
[0038] Furthermore, both the upper pile body 1 and the lower column body 2 are coated with polyurethane coating, thereby improving the corrosion resistance of the fence steel piles. The steel balls are made of stainless steel or galvanized material, forming a complementary protective system with the polyurethane coating, further preventing the intrusion of corrosive media.
[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
