Description

Technical Field

[0001] The embodiments of the present utility model belong to the technical field of cap beam construction safety, and more specifically, relate to an assembled platform for high-altitude operations on cap beams. Background Art

[0002] A cap beam, also known as a cap beam, is a critical component in bridge construction used to support, distribute, and transfer superstructure loads. It is typically installed on piers or piles and can be a reinforced or lightly reinforced concrete beam. Its primary function is to support the bridge superstructure and transfer loads to the substructure and foundation.

[0003] In the prior art, the pouring of the cap beam is usually carried out after constructing an operating platform on multiple piers or pile rows. Among them, the Chinese patent with the document number CN217325017U discloses a cap beam construction bracket with an installation platform. The bracket includes a corbel installed on the pier column. The corbels on both sides of the pier column are provided with an I-beam load-bearing beam. A tie rod is provided between the two load-bearing beams. A plurality of distribution beams are provided on the load-bearing beam. The characteristics are as follows: a cross bar perpendicular to the side of the load-bearing beam is welded to the outside of each load-bearing beam at regular intervals along the longitudinal direction of the load-bearing beam. One end of each cross bar is welded to the load-bearing beam, and a guardrail upright is fixedly provided at the other end. A longitudinal bar parallel to the load-bearing beam is welded to each cross bar at regular intervals. A guardrail cross bar is welded between each guardrail upright to form an installation platform. The installation platform is welded to the load-bearing beam as a whole and hoisted together with the load-bearing beam. Construction personnel can install the tie rods for the load-bearing beam, set up the bracket distribution beam, and perform other operations on the installation platform.

[0004] Although the cap beam construction bracket of the above patent can improve construction safety, it still does not solve some problems existing in the prior art: (1) the extensive use of welding for connection may lead to waste of turnover materials and poor reuse, and the welding parts may be corroded due to the construction cycle, which may easily lead to overall structural instability; (2) the platform has poor adaptability and cannot be used simultaneously for the construction of cap beams of different sizes on piers of different spacing or heights.
