Description

Technical Field

[0001] This utility model relates to the technical field of protective platforms, and in particular to a safety protective operating platform for a girder. Background Technology

[0002] As an important component of the bridge structure, the cap beam plays a vital role in force transmission. It not only needs to bear the pressure of the superstructure of the bridge, but also needs to transfer the pressure it bears to the substructure.

[0003] In bridge cap beam construction, aerial work platforms are core facilities for ensuring worker safety. Currently, the mainstream approach is to use "disassembled assembly" protective platforms; however, disassembled assembly has obvious drawbacks: it requires erecting each pole, crossbar, diagonal brace, step, and safety net on-site, taking an average of 6-8 hours, and the joints are connected with fasteners and bolts, resulting in low platform support. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a safety protection operation platform for cap beams.

[0005] This utility model provides the following technical solution: a safety protection operation platform for a girder, comprising:

[0006] Several clamp assemblies, the clamp assemblies being used for connection with the pier column;

[0007] Support assembly, the support assembly disposed between the plurality of said clamp assemblies;

[0008] Two protective platforms, the two protective platforms being mounted on the support assembly;

[0009] The support assembly includes a plurality of main beams and a plurality of secondary beams; the plurality of main beams are arranged between the plurality of clamp assemblies; the plurality of secondary beams are arranged between the plurality of main beams; and the secondary beams and the main beams are arranged in a cross pattern.

[0010] The clamp assembly includes a first clamp and a second clamp, which are wrapped around the outer wall of the pier column and are fixedly connected.

[0011] Furthermore, the first clamp and the second clamp are provided with first positioning grooves on both the front and rear sides; there are two main beams, and the two main beams are respectively located in the first positioning grooves on the front and rear sides.

[0012] Furthermore, the main beam component includes a beam body, and a plurality of second positioning grooves are provided on the upper part of the beam body, with a plurality of secondary beam components respectively located in the plurality of second positioning grooves.

[0013] Furthermore, the protective platform includes a floor, a protective railing installed on the floor, and multiple openwork areas installed on the protective railing.

[0014] Furthermore, the hollowed-out area includes a through hole opened in the guardrail, a support member provided at the through hole, and a plurality of protective nets provided between the side wall of the through hole and the support member.

[0015] Furthermore, the inner side of the floor extends from left to back to form an installation groove, and the floor is fixedly connected to the sub-beam by bolts, the bolts being distributed within the installation groove.

[0016] Furthermore, the floor is a patterned floor, with the pattern located on its upper surface.

[0017] Furthermore, connecting protrusions are provided on both sides of the guardrail; the connecting protrusions of the two guardrails fit together and are fixedly connected.

[0018] The beneficial effects of this utility model are as follows: By disassembling the work platform into a clamp assembly, a main beam, a secondary beam, and two protective platforms, the modular assembly of this utility model's cap beam safety protection work platform improves assembly efficiency and enhances structural stability. Furthermore, by embedding the main beam into the first positioning groove of the clamp assembly and the secondary beam into the second positioning groove of the main beam, a "groove nesting + cross arrangement" grid structure is formed. This design reduces the connection gaps between the main beam and secondary beam, and between the support assembly and the clamp assembly, making it less prone to relative displacement under stress and significantly improving overall deformation resistance. In addition, the floor of the protective platform is fixed to the secondary beam via bolts in the mounting groove, with the bolt heads not protruding from the floor surface, ensuring a firm connection and avoiding stress concentration caused by protruding bolts. Simultaneously, the guardrails of the two protective platforms are joined together by connecting protrusions, further enhancing the lateral stability of the platform and effectively preventing the protective structure from swaying or tipping over during operation.

[0026] A safety protection work platform for bridge piers, such as Figures 1-3 As shown, it includes: several clamping assemblies 2, support assemblies, and two protective platforms 5;

[0027] like Figures 1-2 As shown, in this embodiment, two clamping assemblies 2 are provided, and the two clamping assemblies 2 are respectively connected to two pier columns 1;

[0028] Specifically, the clamp assembly 2 is used to connect with the pier column 1. It includes a first clamp 21 and a second clamp 22, both of which are semi-circular arc-shaped steel plate structures, and their radii are adapted to the outer diameter of the pier column 1. After the first clamp 21 and the second clamp 22 are wrapped around the outer wall of the pier column 1, the two are fixedly connected by bolts passing through the connecting ear plates at their ends and tightening the nuts. The first clamp 21 and the second clamp 22 are provided with first positioning grooves 23 on both the front and rear sides. The width of the first positioning grooves 23 is adapted to the width of the main beam component 3; the setting of the first positioning grooves 23 facilitates the installation of the main beam component 3.

[0029] like Figures 1-2 As shown, a support assembly is fixedly connected between two clamping assemblies 2; the support assembly includes two main beams 3 and several secondary beams 4;

[0030] Specifically, the two main beam members 3 are located in the first positioning grooves 23 on the front and rear sides, respectively. The length of the main beam member 3 is set according to the spacing of the pier columns 1. The main beam member 3 includes a beam body 31, which is a rectangular steel component, specifically an I-beam. Several second positioning grooves 32 are spaced along the length of the upper part of the beam body 31. The width of the second positioning grooves 32 is adapted to the width of the secondary beam members 4. Several secondary beam members 4 are located in several second positioning grooves 32, and the secondary beam members 4 are arranged perpendicularly to the main beam members 3. The two ends of the secondary beam members 4 are fixedly connected to the corresponding main beam members 3, which can be done by welding or bolt connection. In this embodiment, bolt connection is used.

[0031] like Figures 1-3 As shown, two protective platforms 5 are provided on the support assembly; the two protective platforms 5 are provided on the support assembly and are fixedly connected to each other;

[0032] Specifically, the protective platform 5 includes a floor 54, which is made of patterned steel plate with a patterned surface that effectively prevents slipping. An installation groove 56 extends from left to right along the inner side of the floor 54. The floor 54 is fixedly connected to the sub-beam 4 by bolts. The bolts are distributed within the installation groove 56 to prevent the bolt heads from protruding from the surface of the floor 54 and affecting operation. Furthermore, by placing the installation groove 56 on the inner side of the floor 54, sufficient walking space is provided. A guardrail 51 is installed on the floor 54. The guardrail 51 is a rectangular frame structure, U-shaped in overall form, and is constructed from welded or bolted steel pipes or plates. The guardrail 51 has multiple open areas, including through holes. These through holes are rectangular and support members 53, made of steel pipe or plate, are installed at each through hole. The support members 53 are X-shaped and welded to the upper and lower sidewalls of the through holes. Multiple protective nets 52, made of wire mesh, are installed between the sidewalls of the through holes and the support members 53 and are fixed to the sidewalls of the through holes and the support members 53 by binding or bolts. Connecting protrusions 55, made of steel plates, are installed on both sides of the guardrail 51 and welded to the sides. The connecting protrusions 55 of two guardrails 51 fit together and are fixed together by bolts, forming a single unit.

[0033] The following instructions explain how to set up the safety protection operation platform in this embodiment:

[0034] Installation of clamp assembly 2:

[0035] According to the construction design height, mark the installation position of the clamp assembly 2 on the outer wall of the pier 1 with a marker to ensure that multiple clamps are on the same horizontal line.

[0036] Harness assembly 2 docking: The first clamp 21 and the second clamp 22 are hoisted from both sides of the pier column 1 by the hoisting equipment, so that the two are spliced ​​into a complete circle and attached to the outer wall of the pier column 1, ensuring that the first positioning groove 23 "for installing the main beam 3" on the front and rear sides are aligned.

[0037] Bolt tightening: Align the connecting ear plates at both ends of the clamp, insert high-strength bolts, pre-tighten with a wrench, and then tighten symmetrically with a torque wrench to the specified torque "recommended 30-50 N·m" to ensure that the clamp and the pier 1 are tightly fitted without any loose gaps.

[0038] In other embodiments, if there are multiple piers 1, multiple sets of installations are required, as follows: If the cap beam spans multiple piers 1, repeat the above steps on the remaining piers 1 to install clamp assemblies 2 of the same height. The first positioning grooves 23 of adjacent clamps must be kept on the same axis.

[0039] Installation of main beam component 3:

[0040] Use lifting equipment to hoist the main beam 3 above the clamp assembly 2, and slowly place it into the first positioning slots 23 on the front and rear sides, ensuring that both ends of the main beam 3 rest on the clamp assembly 2 of the corresponding pier column 1.

[0041] Adjust the position of main beam component 3 so that the lengths of the two ends extending from the clamps are consistent. Use a level to check whether main beam component 3 is level. If it is tilted, make fine adjustments.

[0042] The main beam 3 is fixed by connecting it to the threaded hole on the clamp assembly 2 with bolts. The first positioning groove 23 can be used to achieve the effect of quick installation of the main beam 3.

[0043] Installation of sub-beam component 4:

[0044] The sub-beams 4 are hoisted one by one above the main beam 3 and placed into the second positioning groove 32 on the upper part of the main beam 3, so that the sub-beams 4 and the main beam 3 are perpendicular to each other to "form a grid structure" and provide support.

[0045] Adjust the spacing of the sub-beam 4 to be evenly distributed according to the design requirements, and use bolts to fasten both ends of the sub-beam 4 to the main beam 3 to ensure that the nodes do not wobble.

[0046] Installation of protective platform 5:

[0047] The protective platform 5 is hoisted above the support assembly and slowly placed on the sub-beam 4, so that the mounting hole at the mounting groove 56 on the inner side of the floor 54 is aligned with the threaded hole on the sub-beam 4.

[0048] Insert a bolt through the mounting hole in the mounting groove 56, thereby passing through the reserved hole in the floor 54 and connecting to the threaded hole in the sub-beam 4. Tighten with a wrench to ensure that the bolt head is embedded in the mounting groove 56 and does not protrude from the surface of the floor 54 to avoid the risk of tripping.

[0049] Align the connecting protrusions 55 on the sides of the two guardrails 51, insert bolts and tighten them so that the guardrails 51 of the two guardrail platforms 5 form a whole.

[0050] In summary, by disassembling the work platform into a clamp assembly 2, a main beam 3, a secondary beam 4, and two protective platforms 5, this utility model's cap beam safety protection work platform improves assembly efficiency and enhances structural stability through modular assembly. Furthermore, by embedding the main beam 3 into the first positioning groove 23 of the clamp assembly 2 and the secondary beam 4 into the second positioning groove 32 of the main beam 3, a "groove nesting + cross arrangement" grid structure is formed. This design reduces the connection gaps between the main beam and secondary beam, and between the support components and the clamp assembly 2, making relative displacement less likely under stress and significantly improving overall deformation resistance. In addition, the floor 54 of the protective platform 5 is fixed to the secondary beam 4 via bolts in the mounting groove 56, with the bolt heads not protruding from the surface of the floor 54, ensuring a firm connection and avoiding stress concentration caused by protruding bolts. Simultaneously, the guardrails 51 of the two protective platforms 5 are spliced ​​together by connecting protrusions 55, further enhancing the lateral stability of the platform and effectively preventing swaying or overturning of the protective structure during operation.
