The pier is a type of substructure of the bridge, and its construction and quality determine the safety and stability of the bridge operation. Common pier construction uses disc-locked scaffolding and springboards. When using them, the site next to the pier is first leveled and compacted, and then the pier formwork is installed and the main reinforcement is tied. During the process, the safety of workers working at high altitudes needs to be ensured, and the scaffolding needs to be disassembled and assembled many times, which poses certain safety risks and has low construction efficiency.

[0003] The purpose of the utility model is to overcome the deficiencies in the above-mentioned prior art and to provide a safety platform for the construction of double-track pier formwork for conventional railways, which can ensure the safety of workers in construction, high work efficiency, high turnover efficiency, and save construction costs.

[0004] As conceived above, the technical solution adopted by the utility model is: a safety platform for the construction of double-track pier formwork for conventional railways, including a bottom I-beam, a steel tread and a protective device, the bottom I-beam is installed on the back rib channel steel of the pier formwork, with an annular spacing, and its end connecting plate is connected to the pier formwork channel steel, the steel tread is laid on the annularly arranged bottom I-beam, and the protective device is arranged around the bottom I-beam to form a closed ring structure.

[0005] Preferably, the bottom I-beam is I10 I-beam.

[0006] Preferably, the protective device is composed of a guardrail and a guardrail upright pole, the guardrail and the guardrail upright pole are matched, and the guardrail upright pole is provided with a slot through which the guardrail is inserted and fixed together.

[0007] The utility model has the following advantages and positive effects:

[0008] 1. The bottom I-beam of the utility model is connected with the pier formwork as a safety platform to form the main body of the component, which is installed on the back rib channel steel of the pier formwork and is arranged at an annular spacing. Its end connecting plate is connected with the pier formwork channel steel. The steel tread plate is laid on the annularly arranged bottom I-beam, and the protective device is arranged around the bottom I-beam to form a closed ring structure. Therefore, the structure has good stability, the operators can move at will, the construction is convenient, and the work efficiency is improved.

[0009] 2. The utility model is easy to install and disassemble, can be used repeatedly, and greatly saves construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to further understand the content, features and effects of the present invention, the following embodiments are listed and described in detail with reference to the accompanying drawings:

[0018] Referring to the accompanying drawings, the utility model provides a safety platform for the construction of a double-track pier formwork for a conventional railway, comprising a plurality of bottom I-beams, a plurality of steel treads and a protective device, wherein a connecting plate is welded at the end of each I-beam, holes are drilled on the back rib channel steel of the pier formwork to install the plurality of bottom I-beams, the plurality of bottom I-beams are arranged at circumferential intervals, a connecting plate welded at the end of each bottom I-beam is bolted to the pier formwork channel steel, the plurality of steel treads are laid on the plurality of bottom I-beams arranged circumferentially, and the protective device is arranged around the plurality of bottom I-beams to form a closed ring structure.

[0019] Preferably, the bottom I-beam is I10 I-beam.

[0020] Preferably, the protective device is composed of a plurality of guardrails and a plurality of guardrail uprights matched with the guardrails, and the guardrail uprights are provided with slots through which the guardrails are inserted and fixed together.

[0021] The working principle of the utility model is: the bottom I-beam is used as a cross brace and fixed with the channel steel of the pier column template by bolts, so as to ensure the safety of construction. The utility model is made in the template factory, and the on-site crane is installed in place with manual work. When the foundation is poured, the utility model is installed layer by layer along with the pier column template, so that the pier column can be safely constructed. The utility model can solve the safety hazards existing in the high-altitude operation of the pier column, and can save a lot of labor, machinery, and bracket material costs. The scope of application of the utility model is the pier column construction of conventional railways.

[0022] The construction process of this utility model is:

[0023] Step 1: After the pier formwork is installed for 2m, install the first layer of bottom I-beam cross braces and connect them firmly with the pier formwork through bolts, assembling the safety platform and the pier formwork into one;

[0024] Step 2: The crane cooperates with manual lifting to install the steel walkway slabs, and so on to fill the entire ring.

[0025] Step 3: Install the guardrail and guardrail poles, and then install the ladder between the I-beams at the bottom of each floor. Install each floor 2 meters apart as the pier formwork is installed.

[0026] The embodiments described above are only used to illustrate the technical ideas and features of the utility model, and their purpose is to enable technicians in the field to understand the content of the utility model and implement it accordingly. The patent scope of the utility model cannot be limited only by this embodiment, that is, any equivalent changes or modifications made to the spirit disclosed by the utility model still fall within the patent scope of the utility model.
