Description

Technical Field

[0001] This utility model belongs to the field of construction site enclosure technology, and in particular relates to a protective fence used in building construction. Background Technology

[0002] During building construction, high-risk operations such as working at heights and handling heavy objects are often involved, thus placing high demands on safety protection in the work area. Guardrails, as common safety protection facilities on construction sites, primarily serve three functions: first, physically separating the construction area from non-construction areas, effectively restricting unauthorized personnel from entering the construction site; second, providing visual warnings to remind pedestrians and construction workers to be aware of their surroundings; and third, to a certain extent, preventing personal injury caused by falls or falling objects. Especially against the backdrop of rapid urbanization and frequent construction projects, guardrails play an increasingly important role in ensuring construction safety. Currently, there are various forms of guardrails used in building construction, including ground-mounted barriers, crash barriers, and movable fences. Installation methods include both direct ground-mounting and stable installation using support bases.

[0003] However, based on analysis of existing publicly available literature and widely used products on the market, current technology still has significant shortcomings in the following aspects: Weak anti-climbing capability: Many traditional guardrails are designed with a fixed height, failing to effectively prevent children and unauthorized personnel from climbing over them. Once children or pedestrians enter the construction area, personal safety accidents are highly likely. Low installation and disassembly efficiency: Existing guardrails with complex structures or unreasonable assembly methods have low installation efficiency and cumbersome disassembly steps, seriously affecting the construction progress; this is especially inconvenient in scenarios requiring frequent movement or changes in the construction area.

The same reference numerals are used to indicate the same parts.

[0023] The following combination Figures 1 to 4 This invention describes a protective railing for house construction according to one embodiment, comprising:

[0024] Multiple interconnected guardrail units, each including a guardrail bar 101, a post 200, a height adjustment device, and a fixed base 300, allow for faster installation and deployment of the guardrail, meeting the demands of rapid construction. For example, each guardrail unit is 4 meters long horizontally; therefore, 25 units are needed to install a 100-meter-long guardrail. The standardized interface design facilitates interchangeability between guardrail units from different production batches.

[0025] The guardrail includes a top rail 100, a bottom rail 102, and multiple guard bars 101 connecting the top rail 100 and the bottom rail 102. The top rail, bottom rail, and guard bars are preferably made of stainless steel or aluminum alloy; alternatively, high-strength composite materials such as fiberglass reinforced plastic (FRP) can be used to reduce weight. One end of the top rail 100 is provided with a male connector 104, and the other end is provided with a female connector 105. Adjacent guardrail units are connected via the male connector 104 and the female connector 105. The connection structure is a threaded plug-in type or a slotted positioning type connection (the female connector has an internal thread, and the male connector has an external thread), providing reliable pull-out resistance. Each guardrail unit includes at least two posts 200, which are respectively arranged on both sides of the guardrail. The posts 200 are mounted on a fixed base 300 via a height adjustment device. A vertically threaded post 301 is fixed to the upper part of the fixed base 300. The height adjustment device includes a support connecting plate, on which a threaded sleeve 302 is rotatably mounted. The threaded sleeve 302 is mounted on the threaded post 301. The posts 200 are connected to the support connecting plate. In a preferred embodiment, a stop block 304 is fixed to the top of the threaded post 301. The stop block can effectively prevent the threaded sleeve from falling off due to over-tightening. The wall thickness of the posts 200 is preferably between 2mm and 4mm, and the material can be Q235 steel, stainless steel, or other alloy materials that meet the structural strength requirements. To improve the visibility of the structure at night or in low-light environments, reflective film can be pasted on the surfaces of the crossbars 201 and the top bar 202, or yellow / red and white warning stripes can be sprayed on them.

[0026] The height adjustment device allows for precise adjustment of each post's height according to variations in ground level, effectively resolving safety hazards such as tilting and loosening caused by uneven ground in traditional guardrails. Furthermore, the overall height of the guardrail can be adjusted according to the required protection level, for example, by raising the guardrail in areas with higher protection requirements. The threaded sleeve is screwed onto the externally threaded post; rotation allows the support connecting plate to move up and down, thereby raising and lowering the entire post. The adjustment operation is simple and convenient. The addition of an adjustment handle further enhances operational ease, allowing for easy height adjustment even under load, effectively improving the guardrail's adaptability and safety.

[0027] The design of multiple interconnected guardrail units allows for flexible length adjustment based on actual construction site needs, exhibiting excellent modular assembly characteristics. The top bars of the guardrail are equipped with male and female connectors, enabling quick connection between adjacent guardrail units, improving installation efficiency and enhancing overall structural stability. This structure not only facilitates rapid erection and dismantling by construction workers, making it suitable for work scenarios with frequent changes in construction areas, but also helps save storage and transportation space and costs, demonstrating excellent practicality and economy.

[0028] In such Figure 1 In a preferred embodiment shown, the lower part of the protective rod is a straight rod, and the upper part of the protective rod is a curved structure facing one direction; correspondingly, the structure of the column is the same as that of the protective rod, such as... Figure 3 As shown, the column includes straight sections and curved sections, with the curved sections having an S-shaped structure. (Combined with...) Figure 3 As shown, the bottom of the guardrail erected by the guardrail with the above structure can be fitted with a fixed base. The fixed base is at least partially located in the space below the right side of the guardrail and the post, which has a more aesthetically pleasing effect. Of course, the guardrail and the post can also be designed as a vertical structure.

[0029] In such Figure 3 and Figure 4 In a preferred embodiment, the supporting connecting plate includes a vertical plate 201, a horizontal plate 202, and a base plate. The base plate and the horizontal plate 202 are vertically connected to both sides of the vertical plate 201, and the base plate and the horizontal plate 202 are arranged facing opposite directions. The bottom of the column 200 is mounted on the base plate, which supports the column. In a more preferred embodiment, a connecting plate is also vertically fixed to the vertical plate. The connecting plate is located above the base plate and parallel to the base plate, and the column passes through the mounting hole in the middle of the connecting plate. According to the structure of the preferred embodiment, the column and the supporting connecting plate can be connected more stably, preventing the column from tilting.

[0030] To prevent the column from tilting or wobbling when adjusting the column height, the above embodiment is further improved by providing a guide rod 305 on the side of the fixed base 300 near the column 200. Both the base plate and the column 200 are provided with holes that fit the guide rod 305. That is to say, at least the lower end of the column is a hollow structure that can accommodate the guide rod, and the guide rod is inserted into the lower end of the column.

[0031] In a preferred embodiment of a protective fence used in house construction, such as Figure 3 and Figure 4 As shown, an adjusting handle 303 is fixedly connected to the outer periphery of the threaded sleeve 302. Specifically, the adjusting handle is a cross-shaped rod. By adjusting the handle, the threaded sleeve can be rotated using leverage, avoiding the problem that ordinary operators are unable to rotate the threaded sleeve due to the large weight supported by the column.

[0032] In a preferred embodiment of a protective fence used in house construction, such as Figure 3 and Figure 4 As shown, the fixed base 300 has exposed wing plates on both sides. The wing plates have an L-shaped cross-section. The vertical surface of the wing plates is attached to the fixed base body. The wing plates can increase the contact area between the fixed base and the ground, thereby making the fixed base more stable and preventing the guardrail from tipping over due to the tipping of the fixed base.

[0033] In a preferred embodiment of a protective fence used in house construction, such as Figure 1 and Figure 3 As shown, the upright and the top rail of the guardrail 100 are connected by a mounting clamp 103. The mounting clamp includes a first U-shaped portion and two second U-shaped portions connected to the first U-shaped portion. The ends of the second U-shaped portions are locked using baffles and nuts. Alternatively, the upright and the top rail of the guardrail can be connected by welding to prevent loosening.

[0034] This utility model, through its plug-in connection structure, allows for the rapid assembly and disassembly of multiple guardrail units, resulting in a stable overall structure and high installation efficiency. The height adjustment device enables the guardrail to adapt to different terrain variations, improving its versatility and flexibility on construction sites. Modular design and standardized components facilitate large-scale production and transportation, while reducing maintenance and replacement costs, making it highly valuable for widespread application.

[0035] The technical features disclosed above are not limited to the combinations of the disclosed features with other features. Those skilled in the art can also make other combinations of the technical features according to the purpose of the utility model in order to achieve the purpose of the utility model.
