Description

Technical Field

[0001] This utility model relates to the field of cast-in-place pile construction technology, specifically a protective device for the opening of a cast-in-place pile on a steel platform. Background Technology

[0002] In today's construction industry, with the continuous advancement of various large-scale construction projects, cast-in-place pile construction on steel platforms is widely used as a common and crucial foundation construction method. These pile openings are usually reserved for the pouring of cast-in-place piles. Their size and depth vary depending on the engineering design, but without exception, they are all directly exposed to the busy environment of the construction site. When construction workers are performing various construction operations on the steel platform, such as carrying building materials, operating construction machinery, and tying rebar, their attention is often focused on the task at hand, and they can easily overlook the pile openings under their feet, thus accidentally stepping into or falling into them, resulting in serious injuries or fatalities.

[0003] Traditional protective measures are often rudimentary and lack specificity. Some construction sites use only simple ropes, planks, or makeshift fences to try to prevent personnel from approaching the pile hole openings. However, these methods are unstable and easily shifted, damaged, or even collapsed during construction due to external forces such as collisions and wind. They cannot effectively prevent personnel from accidentally falling into the openings, leading to frequent serious accidents and injuries. Furthermore, with the diversification and complexity of construction projects, the structure of steel platforms and the size and shape of pile hole openings vary greatly. Traditional protective devices are difficult to adapt to this diversity, often requiring significant time and manpower for on-site modification or customization. This not only reduces construction efficiency but also increases construction costs. Moreover, in the complex environment of construction sites, traditional protective devices lack effective warning functions and cannot promptly attract the attention of construction workers, further increasing safety risks.

This greatly improves the comprehensiveness and reliability of protection, reduces the safety risks at the construction site, and effectively prevents personnel from falling while working above by the top sealing part, providing a stronger guarantee for construction safety.

[0036] Working principle: When using:

[0037] Step 1: First, clean the area around the pile opening on the steel platform 1 to ensure there are no debris, water accumulation, or other factors that may affect the installation of the protective device. At the same time, check the flatness of the surface of the steel platform 1 and make appropriate repairs if necessary to ensure the stability of the subsequent installation of the trapezoidal support block 2 and the protective device.

[0038] Step 2: The warning plate 313 fixedly installed on the outer wall of protective enclosure 1 311 and protective enclosure 2 312 faces outward, which can play an effective warning role. The steel platform magnetic block 315 is attracted: Since the steel platform magnetic block 315 is fixedly installed in the mounting groove 314 on the bottom outer wall of the trapezoidal support block 2, and the steel platform magnetic block 315 is attracted to the steel platform 1, this step can further enhance the stability of the connection between protective enclosure 1 311 and protective enclosure 2 312 and the steel platform 1, and prevent them from shifting during use.

[0039] Step 3: The sliding guardrail plates 3115, which are equidistantly fixed to the outer wall of protective fence 1 311, are slidably connected to the guardrail grooves 3116, which are equidistantly opened on the outer wall of protective fence 2 312. By adjusting the position of the sliding guardrail plates 3115 within the guardrail grooves 3116, the relative position between protective fence 1 311 and protective fence 2 312 can be adjusted to accommodate pile openings of different sizes. The positioning rectangular block 3114, which is fixedly installed on one side of the outer wall of protective fence 1 311, cooperates with the telescopic positioning block 3113, which is fixedly installed on the outer wall of protective fence 2 312. The positioning rectangular block 3114 and the telescopic positioning block 3113 cooperate with each other. Rectangular grooves are provided on each block 3113. Rectangular slide plates 3117 are slidably connected inside the rectangular grooves. By moving the rectangular slide plates 3117, the tightness of the connection between the first protective plate 311 and the second protective plate 312 can be finely adjusted so that it fits better against the edge of the pile hole. Then, one end of the threaded rod 3118 connected to the internal thread of the hexagonal nut extends into the interior of the telescopic positioning block 3113 through the hexagonal nut and matches it with the positioning holes equidistantly opened on the rectangular slide plates 3117, thereby fixing the position of the rectangular slide plates 3117 and ensuring that the first protective plate 311 and the second protective plate 312 are firmly connected.

[0040] Step 4: Install the rectangular clamp rod 319 into the rectangular groove 316 on the first protective enclosure 311 and the second protective enclosure 312. The top of the rectangular clamp rod 319 is fixedly installed with a fixing plate 3111. The fixing plate 3111 has a positioning through hole. The hexagonal bolt 3112 is threaded through the positioning through hole and threadedly connected to the threaded connection positioning hole 318 on the top of the first protective enclosure 311 and the second protective enclosure 312, thereby further fixing the first protective enclosure 311 and the second protective enclosure 312, so that they form a stable protective enclosure structure around the pile hole.

[0041] Step 5: Place top sealing plate 1 411 and top sealing plate 2 412 on top of protective enclosure 1 311 and protective enclosure 2 312. The fixing lug 1 414 fixedly installed on one side of the outer wall of top sealing plate 1 411 and the fixing lug 2 413 fixedly installed on one side of the outer wall of top sealing plate 2 412 should be in an easily operable position. Simultaneously, the sliding rod 415 equidistantly fixedly connected to the other side of the outer wall of top sealing plate 1 411 should correspond to the sliding groove 416 equidistantly opened on the other side of the outer wall of top sealing plate 2 412. Connect top sealing plate 1 411 and top sealing plate 2 412: Insert the sliding rod 415 of top sealing plate 1 411... The top sealing plate 411 and the top sealing plate 412 are inserted into the sliding groove 416 so that they can slide relative to each other, thereby adjusting the coverage area of ​​the top sealing plate 411 and the top sealing plate 412 to accommodate the top opening of the protective enclosure of different sizes. Then, the positioning installation round blocks 417, which are fixedly installed at equal intervals on the bottom outer walls of the fixing lugs 414 and the fixing lugs 413, are aligned with the positioning installation grooves 317, which are opened at equal intervals on the top outer walls of the protective enclosure 311 and the protective enclosure 312. The positioning installation round blocks 417 are then engaged and installed in the positioning installation grooves 317 to complete the installation of the top sealing part 4 of the adjustment plate and realize the top protection of the pile position opening.
