Description

Technical Field

[0002] With the rapid development of infrastructure construction in my country, bridge engineering, particularly bridge piers, serves as a crucial component connecting the foundation and the beam, bearing various loads including the beam's self-weight, vehicle loads, and wind loads. Currently, pier reinforcement construction commonly employs temporary scaffolding platforms: temporary supports are erected on the pier cap or pier formwork using steel pipe couplers or disc-lock scaffolds to complete the reinforcement binding work. This method has the following technical drawbacks: traditional scaffolding or temporary supports lack stability, have narrow operating surfaces, require frequent worker movement, and pose a risk of falls from height; these supports require repeated disassembly and assembly, affecting construction progress and increasing labor costs, especially when the pier's single pour height is large, resulting in significant turnaround time; and traditional supports require large installation sites, particularly in offshore operations or when space is limited by sheet pile cofferdams for pier caps. As bridge construction increasingly becomes modular and mechanized, traditional temporary supports are insufficient to meet the demands for safe and efficient construction. Utility Model Content

[0025] like Figures 1-3 As shown in the figure, this utility model embodiment provides a pier reinforcement construction platform, including several layers of sub-platforms 1 and connecting members. The several sub-platforms 1 are detachably connected by the connecting members and are stacked along the height direction.

[0026] The sub-platform 1 includes a steel frame 2, a walking platform 3, and guardrails 4. The steel frame 2 includes a bottom frame 21, a top frame 22, and vertical supports 23. The bottom frame 21 and the top frame 22 are welded together from several members around the outer perimeter of the pier 7. The bottom frame 21 and the top frame 22 are vertically aligned. The vertical supports 23 are used to vertically support the top frame 22 on the bottom frame 21, forming a rigid steel frame 2. Figure 3 As shown, the walking platform 3 is made of steel plate. Preferably, the upper surface of the walking platform 3 is provided with an anti-slip texture. The walking platform 3 can take various forms: the extension section of the walking platform 3 in each direction is cut from a larger steel plate; or, the walking platform 3 is made of several steel plates welded or bolted together and laid on the base frame 21; or, several steel plates are welded to the base frame 21 and spliced ​​together to form the walking platform 3. The walking platform 3 is provided with a passageway for people to get on and off at at least one corner. In this embodiment, the walking platform 3 is provided with the passageway at all four corners. Preferably, a liftable cover plate 31 is provided at the passageway. The cover plate 31 is square, with one side hinged to the base frame 21 or an adjacent steel plate, and the remaining three sides free and resting on the base frame 21 to maintain a normally closed state. When the cover plate 31 is opened, the passageway is formed. The guardrail 4 is assembled from several rods, with its bottom fixed to the steel frame 2, and is located at least on the outer side of the walking platform 3 in the extending direction. In this embodiment, the guardrail 4 is provided on both sides of the walking platform 3.

[0027] like Figure 1 or Figure 2 As shown, the vertical support 23 includes at least a first support column 231. A plurality of first support columns 231 are vertically arranged in the corner area of ​​the steel frame 2, with their top and bottom ends connected to the bottom frame 21 and top frame 22 respectively, to provide core support. Preferably, the number of first support columns 231 in a corner area is 2, 3, or 4. The first support columns 231 are made of shaped steel components, preferably angle steel, channel steel, or square steel. The top and bottom ends of the first support columns 231 are welded to the top frame 22 and the bottom frame 21 respectively. Preferably, the steel frame 2 also includes a plurality of corner braces 24. The corner braces 24 are provided on multiple extended surfaces at the connection nodes between the first support columns 231 and the bottom frame 21 or the top frame 22, thereby improving the overall rigidity of the steel frame 2. In this embodiment, the corner braces 24 are triangular plates. For corners with passageways, at least two first support columns 231 are arranged side-by-side and fixed together by a plurality of horizontally arranged crossbars 51 to form a ladder 5 for personnel to ascend and descend. Correspondingly, in this embodiment, ladders 5 are provided at each of the four corners of the construction platform.

[0028] The vertical support 23 also includes a plurality of second support columns 232. The second support columns 232 vertically connect the bottom frame 21 and the top frame 22, and the plurality of second support columns 232 are spaced apart between adjacent corners of the steel frame 2. The number of second support columns 232 between adjacent corners is adjusted according to the specific span. It is easy to understand that the second support columns 232 can serve as vertical components of the next layer of guardrail 4. As part of the guardrail 4, the horizontally arranged handrail 41, while being fixed to the first support columns 231 and the second support columns 232, also improves the lateral stability of the vertical support 23. The second support columns 232 and the guardrail 4 are made of steel components, preferably steel pipes. The construction platform is equipped with safety belt suspension anchor points on the guardrail 4, the first support column 231, or the second support column 232.

[0029] The sub-platform 1 is designed according to the design drawings of the bridge pier 7 and prefabricated in the workshop. Then, multiple sets of sub-platforms 1 are transported to the construction site. The bottom sub-platform 1 is hoisted and placed onto the abutment or the corbel 6 of the pier body formwork of the bridge pier 7. The top frame 22 of the lower sub-platform 1 is detachably connected to the bottom frame 21 of the upper sub-platform 1 using the connecting components. Each layer of sub-platform 1 is assembled sequentially upwards to obtain the construction platform. Preferably, the connecting components are bolt assemblies. Preferably, the connecting components are high-strength bolts.

[0030] In summary, the construction platform provided by this utility model embodiment has the following advantages: (1) Improved construction efficiency: Each sub-platform 1 is prefabricated in the workshop in a modular manner and can be disassembled and assembled on site by high-strength bolts. It does not require a large construction site and complicated on-site construction, which is not only conducive to quality control, but also greatly improves construction efficiency. During construction, the construction platform has multiple sub-platforms 1, which facilitates synchronous construction at different heights and greatly shortens the construction period. After the reinforcement construction is completed, the construction platform can be hoisted and reused as a whole or in modules, saving the time and labor costs of repeated disassembly and assembly. (2) Better structural performance: The construction platform adopts a rigid steel structure frame as a whole, which is structurally stable, has good bearing capacity, and has better anti-overturning capacity than the traditional pier-side reinforcement construction platform. The compact structure of the construction platform in the lateral direction also allows it to be erected on the pier cap or pier body formwork corbel, making the supporting foundation more stable. (3) In addition, each sub-platform 1 is fully equipped with guardrails 4, anti-slip walking boards 3, and safety belt suspension anchors, which provide all-round protection for construction personnel and reduce the risk of falling from height.

[0031] The above description is merely a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All technically equivalent modifications made based on the content of the present utility model specification shall fall within the protection scope of the present utility model.
