They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] As attached Figure 1-3 As shown in this embodiment, a prefabricated safety protection platform for the construction of a girder support includes a platform base plate 1 and platform side railings 2. Support columns 3 are provided at the corners of the platform base plate 1, a hoisting window 4 is opened in the middle of the platform base plate 1, and several assembly and fixing holes 5 are provided on both sides of the platform base plate 1 for connecting and fixing the entire prefabricated safety protection platform. The platform side railings 2 are installed on the outer periphery of the platform base plate 1, forming passageways on both sides of the prefabricated safety protection platform. This prefabricated safety protection platform for girder support construction has a simple structure, is easy to assemble, and can be quickly installed and fixed for use. It is mainly suitable for the overall lifting and lowering construction process of girder supports. After the overall lifting of the girder support, it can be quickly assembled and installed to fill the safety platform gaps required for the overall lifting and lowering of the girder support, ensuring the safety of subsequent construction operations. Safety protection is a crucial aspect during the construction of girder supports. Traditional protective measures often suffer from problems such as complex installation and insufficient stability. This prefabricated safety protection platform, through modular design, uses the platform base plate 1 and side railings as core components, achieving rapid assembly and disassembly. Support columns 3 are installed at the corners of the platform base plate 1. These columns not only provide stable support but also enhance the structural strength of the entire platform through their tight connection with the base plate. The hoisting window 4 in the middle is designed with the actual needs of the construction process in mind, accommodating both the hoisting needs of the cap beam support and the safety protection needs of construction operations, thus improving construction efficiency. The mounting and fixing holes 5 on both sides ensure the platform is firmly installed in different construction scenarios, providing reliable stability whether fixed to the ground or connected to other structures. The platform side railings 2 further ensure the safety of construction personnel, while the design of the access door takes into account the convenience of construction personnel passage, so that the entire platform meets safety requirements while also considering the ease of construction.

[0023] As a feasible implementation method, the hoisting window 4 is equipped with a window opening and closing door 6. In actual construction, the frequent hoisting operations place higher demands on the safety and functionality of the hoisting window 4. To meet this requirement, this embodiment provides a window opening and closing door 6 on the hoisting window 4. This not only enables hoisting operations but also allows the door to be closed during non-hoisting periods, effectively preventing construction personnel from accidentally falling and enhancing the platform's safety.

[0024] Specifically, as shown in the attached drawings, the platform base plate 1 includes a first base plate 101 and a second base plate 102. The second base plate 102 is installed on the first base plate 101 via the supporting columns 3, forming a double-layer safety protection platform. In some complex construction scenarios, a single-layer protection platform cannot adequately meet the safety protection requirements of construction operations. Therefore, this embodiment adopts a double-layer base plate structure. The first base plate 101 and the second base plate 102 are connected by the supporting columns 3, forming a stable double-layer platform. This structure not only significantly enhances the overall stability of the platform but also effectively disperses various loads generated during construction, reducing safety hazards caused by excessive local stress. The double-layer base plate design also provides more operating space for construction personnel, especially when multi-level operations or equipment installation are required, the advantages of the double-layer structure are more obvious. In addition, the double-layer base plate can be customized according to specific needs, such as setting additional fixing devices or protective facilities on the second base plate 102, further enhancing the platform's multi-functionality and adaptability.

[0025] Specifically, as shown in the attached drawings, column insertion slots 7 for installing the support columns 3 are provided on the upper side of the corner of the first base plate 101 and the lower side of the corner of the second base plate 102. Corresponding column fixing holes are provided at both ends of the column insertion slots 7 and the support columns 3. To ensure a secure connection between the support columns 3 and the base plate, this embodiment provides column insertion slots 7 on the upper side of the corner of the first base plate 101 and the lower side of the corner of the second base plate 102. This design allows the support columns 3 to be precisely inserted into the designated positions on the base plate, avoiding structural instability caused by installation deviations. The column fixing holes corresponding to the column insertion slots 7 and the two ends of the support columns further enhance the reliability of the connection. By passing bolts or other fasteners through the fixing holes, the support columns are firmly fixed to the base plate, which is not only simple to operate but also able to withstand large loads. In actual construction, this optimized design greatly improves the assembly efficiency and stability of the platform, reducing the risk of safety accidents caused by loose or unstable connections.

[0026] Specifically, as shown in the attached drawings, the periphery of the first base plate 101 and the second base plate 102 is provided with several guardrail insertion slots 8 for installing the platform side guardrail 2. Guardrail fixing holes should be provided on the guardrail insertion slots 8 and the mounting beams of the platform side guardrail 2. The platform side guardrail 2 is a key component ensuring the safety of construction personnel; therefore, its installation firmness and stability are crucial. In this embodiment, multiple guardrail insertion slots 8 are provided around the periphery of the first base plate 101 and the second base plate 102. These slots provide precise positioning for the installation of the platform side guardrail 2. The guardrail insertion slots 8 match the guardrail fixing holes on the mounting beams of the platform side guardrail 2 and are fixed with bolts or other fasteners, ensuring a stable installation of the guardrail. This design not only improves the impact resistance and stability of the guardrail but also facilitates quick disassembly and replacement, adapting to different construction needs. In practical applications, this reinforcement effectively prevents accidents caused by loose or damaged guardrails, greatly improving the level of construction safety.

[0027] Specifically, as shown in the attached drawings, the platform side railing 2 includes a folding railing, which comprises an upper railing 201 and a lower railing 202 connected by a hinge 9. Considering the space constraints and ease of transportation at the construction site, the platform side railing 2 in this embodiment adopts a folding railing design. The folding railing consists of an upper railing 201 and a lower railing 202, which are connected by a hinge 9. This design allows the railing to be folded up when not in use, greatly saving space and facilitating transportation and storage. During construction, the folding railing can be quickly unfolded and secured according to actual needs, providing immediate safety protection for construction personnel. The folding railing design not only improves the flexibility and adaptability of the platform but also reduces transportation and storage costs caused by the excessive size of the railing, enhancing the overall economy and practicality of the platform.

[0028] Specifically, as shown in the attached diagram, the hinge 9 is located on the outer side of the folding guardrail, and bolt fixing holes are provided on the inner side of the folding guardrail. The upper guardrail 201 and the lower guardrail 202 are fixed together on the inner side of the folding guardrail by bolts 10. To ensure the stability of the folding guardrail during use, this embodiment optimizes the fixing method. The hinge 9 is located on the outer side of the folding guardrail, which not only facilitates the folding and unfolding of the guardrail but also effectively prevents construction workers from accidentally colliding with the hinge 9 while working on the inner side of the guardrail, thus preventing safety hazards. The bolt fixing holes on the inner side of the folding guardrail allow the upper guardrail 201 and the lower guardrail 202 to be tightly fixed together by bolts 10, which not only enhances the overall strength of the guardrail but also effectively prevents the guardrail from loosening or deforming due to external impacts. In actual construction, this design ensures the stability and reliability of the folding guardrail in various complex environments, providing better safety protection for construction workers.

[0029] Specifically, as shown in the attached diagram, the prefabricated safety protection platform is fixedly installed using flange plate bolt connections. On the construction site, the installation efficiency and connection reliability of the platform directly affect the construction progress and safety. This embodiment adopts a flange plate bolt connection method, which features fast installation speed and a strong, reliable connection. The use of flange plates not only provides sufficient contact area to ensure connection stability but also effectively disperses stress at the connection points, reducing connection failures caused by excessive local stress. Bolted connections facilitate rapid on-site assembly and disassembly, adapting to different construction needs. Through flange plate bolt connections, the entire prefabricated safety protection platform can be firmly installed in the designated location, providing reliable support and protection whether fixed to the ground, a support frame, or other structures. This installation method not only improves construction efficiency but also reduces safety risks caused by improper installation.

[0030] As can be seen, based on the above structural design, the prefabricated safety protection platform for the construction of the cap beam support of this utility model has a simple structure, is easy to assemble, and can be quickly installed and fixed for use. It is mainly applicable to the overall lifting and lowering construction process of the cap beam support. After the cap beam support is hoisted as a whole, it can be quickly assembled and installed to fill the empty safety platform space required for the overall lifting and lowering construction of the cap beam support, and ensure the safety of subsequent construction operations.
