Description

Technical Field

[0001] The present application relates to the technical field of operating platforms, and in particular to an integrated operating platform for prefabricated cap beams and prestressed end capping. Background Art

[0002] The cap beam is an important component of the bridge structure. The bridge is used to support the bridge deck and bear vehicle loads. The cap beam is located at the upper part of the bridge and spans between the piers or abutments. The cap beam plays a connecting and supporting role. Prefabricated cap beams are often used during bridge construction. Prefabricated cap beams are beams prefabricated in the factory and then transported to the site for installation. They have the advantages of fast construction speed and controllable quality.

[0003] During the process of prefabricating the cap beam, anchor plates are embedded at both ends of the cap beam. Later, during the construction of the bridge, after the prefabricated cap beam is installed on the upper part of the bridge, the prestressed steel strands are passed through the anchor plate at one end and out of the anchor plate at the other end, so that the prestressed steel strands pass through the cap beam. Then, the prestressed steel strands are tensioned by tensioning jacks to apply prestress to the steel strands. Under the action of the prestressed steel strands, the prestress can offset part of the compressive stress caused by the load, thereby reducing the actual stress borne by the concrete, thereby improving the bearing capacity of the structure. Finally, the prestressed steel strands are anchored in the cap beam through the anchor plate.

[0004] When construction workers pass the prestressed steel strands into the cap beam, they often place scaffolding at both ends of the cap beam, and the construction workers stand on the top of the scaffolding to operate. However, when the ground is not flat, the scaffolding placed on the ground will become unstable, making it less safe for construction workers to stand on the top of the scaffolding to work. Summary of the invention

[0005] In order to improve the safety of construction workers when constructing at both ends of the cap beam, the present application provides an integrated operation platform for prefabricated cap beam prestressed end sealing.

The construction workers on the operating platform 2 pass the prestressed steel strands through the anchor pad 13 at one end and out of the anchor pad 13 at the other end. After that, the construction workers standing on the operating platforms 2 at both ends use tensioning jacks to tension the prestressed steel strands. The operating platform 2 is installed on the cap beam 1. Therefore, when the ground is uneven or the ground is narrow, the installation of the operating platform 2 is less affected. Under the action of the operating platform 2, the safety of the construction workers when constructing at both ends of the cap beam 1 can be improved.

[0034] Reference Figure 2 The operating platform 2 includes a supporting frame 21. In the embodiment of the present application, the supporting frame 21 is a rectangular frame.
