Description

Technical Field

[0001] This application relates to the field of bridge pier construction equipment technology, and in particular to a temporary work platform for bridge pier construction. Background Technology

[0002] Piers are the load-bearing structures in civil engineering that support the superstructure. Pier cross-sections are mostly circular, but elliptical, square, curved, parabolic, and other irregular shapes also exist. They are an important component in highway bridges, railway bridges, pedestrian bridges, overpasses, ramp bridges, and pedestrian bridges.

[0003] Currently, most bridge temporary work platform construction uses scaffolding, with workers standing on temporarily erected scaffolding. This greatly limits the number of personnel that can be deployed, and the erection of scaffolding poses certain safety hazards, seriously affecting the efficiency and cost of pier construction.

This significantly improves work efficiency and reduces construction costs. Furthermore, the bottom support is a welded, integral support that surrounds the pier, while the upper supports are welded to the bottom or upper platforms below them, also surrounding the pier, thus ensuring the stability of the temporary work platform and reducing safety hazards.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0032] Currently, scaffolding is mostly used for temporary bridge construction platforms. Scaffolding is a temporary construction tool erected on construction sites to facilitate worker operations and vertical and horizontal transportation. However, scaffolding has poor stability, posing certain safety hazards. Furthermore, workers can only work at the top of the scaffolding, significantly limiting the number of workers and resulting in lower work efficiency and higher construction costs.

[0033] This application provides a temporary work platform for bridge pier construction. The platform consists of a bottom platform 100 and several upper platforms 200 arranged sequentially from bottom to top, forming a multi-layered temporary work platform. Workers are supported by a bottom support component 120 and several upper support components 220, allowing multiple workers to work simultaneously across multiple levels. This significantly improves work efficiency and reduces construction costs. Furthermore, the bottom support 110 is a welded integral support surrounding the pier, and the upper supports 210 are welded integrally with the bottom platform 100 or upper platform 200 below it, also surrounding the pier, thus ensuring the stability of the temporary work platform and reducing safety hazards. This solves the problems of current scaffolding-style work platforms, which severely limit the number of workers and pose certain safety hazards, seriously affecting the efficiency and cost of pier construction.

[0034] The specific structure of the temporary work platform provided in this application will be described in detail below with reference to the accompanying drawings.

[0035] Figure 1 This is a structural diagram of the temporary work platform provided in this application. Figure 2 yes Figure 1 Partial front view sectional view. (Refer to...) Figure 1-2 As shown, this application embodiment provides a temporary work platform for bridge pier construction, including a bottom platform 100 and several upper platforms 200. The bottom platform 100 and several upper platforms 200 are arranged from bottom to top to form a multi-layer temporary work platform, with the bottom platform 200 located at the bottommost layer of the multi-layer temporary work platform.

[0036] The bottom platform 100 includes a bottom support 110 and a bottom load-bearing component 120. The bottom support 110 is a welded integral support that surrounds the pier. If the entire outer wall of the pier is being constructed, there can be a certain gap between the bottom support 110 and the outer wall of the pier for ease of use. If only a part of the pier is being constructed, the bottom support 110 can be fitted to the outer wall of the pier to ensure the stability of the bottom support 110. The bottom load-bearing component 120 is set on the bottom support 110 and is used to support workers. Workers stand on the bottom load-bearing component 120 to carry out construction on the pier. The bottom support 110 can be 1.8m high, allowing workers to stand on the ground or the pier base to carry out construction on the area of ​​the pier located under the bottom load-bearing component 120.

[0037] The upper platform 200 includes an upper support 210 and an upper load-bearing component 220. The upper support 210 is welded integrally with the lower platform 100 or the upper platform 200 located below it. The upper support 210 surrounds the pier column. The upper support 210 can have a certain distance from the outer wall of the pier column or be close to the outer wall of the pier column, thereby ensuring the stability of the upper support 210. The upper load-bearing component 220 is set on the upper support 210 and is used to support the workers. The height of the upper support 210 can be 1.8m.

[0038] Based on the calculation that workers can work in a height range of 0-1.8m, when only the bottom platform 100 is set up, workers can stand on the bottom surface and the bottom bearing component 120 to work, and workers can work in a height range of 0-3.6m for the pier. If the actual height of the pier being constructed is greater than 3.6m, an upper platform 200 can be set up on the top of the bottom platform 100. According to the calculation that each upper platform 200 can increase the construction height by 1.8m, if the pier is 6m high, two upper platforms 200 can be set up sequentially on the top of the bottom platform 100, thus forming four construction areas from bottom to top, each area being 1.8m, thereby meeting the construction requirements for a 6m high pier.

[0039] This application provides a temporary work platform for bridge pier construction. The platform consists of a bottom platform 100 and several upper platforms 200 arranged sequentially from bottom to top, forming a multi-layered temporary work platform. Workers are supported by a bottom support component 120 and several upper support components 220, allowing multiple workers to work simultaneously across multiple levels. This significantly improves work efficiency and reduces construction costs. Furthermore, the bottom support 110 is a welded integral support surrounding the pier, and the upper supports 210 are welded integrally with the bottom platform 100 or upper platform 200 below it, also surrounding the pier, thus ensuring the stability of the temporary work platform and reducing safety hazards. This solves the problems of current scaffolding-style work platforms, which severely limit the number of workers and pose certain safety hazards, seriously affecting the efficiency and cost of pier construction.

The bottom outer support ring is similar in shape to the bottom inner support ring and is fixed to the second end of multiple bottom diagonal rods 112, that is, welded to the bottom end of the bottom diagonal rods 112. Multiple bottom support plates 123 are evenly laid between the bottom inner support ring and the bottom outer support ring. The bottom support plate 123 supports the workers during construction.

The first end of each upper column 211 is fixed to the lower inner ring or upper inner ring located below it. That is, the top of the upper column 211 is welded to the lower inner ring 121 or the upper inner ring 221 located below it. The specific welding position can be referred to Figure 3 As shown, the welding position is at the upper end of the inner support rod. The second ends of multiple upper column 211 are all fixed to the upper inner support ring of the same layer, that is, the upper end of the upper column 211 is welded to the lower surface of the upper inner support rod 221 of the same layer.

[0044] The first ends of multiple upper-layer diagonal rods 212 are all fixed to the bottom outer support ring or the upper outer support ring located below them.
