Description

Technical field:

[0001] The utility model belongs to the field of bridge construction, in particular to a bridge construction cap beam anchor sealing safety operation platform. Background technology:

[0002] The cap beam is a crucial component of bridge construction. It's a horizontal beam installed atop bent pile piers to support, distribute, and transfer the loads of the superstructure. Also known as a cap beam, this beam is constructed of reinforced or lightly reinforced concrete and placed on piers (or abutments) or pile rows. Its primary function is to support the bridge superstructure and transfer all loads to the substructure. Sometimes the piles connect directly to the cap beam, while others connect the piles to the columns and then to the cap beam.

[0003] During the construction of a bridge, it is necessary to carry out anchor sealing operations on its cap beam. Specifically, it is an operation to seal and cover the anchors of the cap beam. In traditional processes, scaffolding needs to be erected in advance before the anchor sealing operation. The site requirements are high, and the scaffolding can only be erected after the construction site is hardened, resulting in a large investment in construction costs. When the anchor sealing construction of a cap beam is completed, the original scaffolding needs to be disassembled and transported to the next cap beam anchor sealing station, and then the frame is repeatedly erected, resulting in a long cap beam anchor sealing operation cycle, low construction efficiency, and a high construction safety risk. Utility model content:

[0004] The purpose of the utility model is to provide a safe operation platform for sealing and anchoring cap beams during bridge construction, and to overcome the deficiencies of the above-mentioned prior art, which effectively solves the existing problems of high construction cost and low construction efficiency of the original sealing and anchoring cap beams.

[0005] The content of the utility model: A safe operation platform for sealing and anchoring cap beams during bridge construction, comprising a working platform, a first guardrail net vertically mounted on the top walls at both ends of the working platform, a second guardrail net vertically mounted on the top wall at the outer end of the working platform, a notch matching the end of the cap beam is opened on the working platform, and the working platform is connected to the bridge body via a fixing assembly.

[0006] Furthermore, the fixing assembly includes a pair of longitudinal cantilever frames, the bottom ends of the longitudinal cantilever frames are fixedly connected to the top wall of the working platform, and the top ends of the longitudinal cantilever frames are fixedly connected to transverse cantilever frames matching the top surface of the bridge, and the inner ends of the transverse cantilever frames are fixedly connected to the wet joint steel bars of the bridge deck.

[0007] Furthermore, reinforcing ribs are connected to the transverse cantilever frame.

[0008] Furthermore, a connecting rod is provided in the notch, and both ends of the connecting rod are fixedly connected to the working platform.

[0009] Furthermore, lifting ears are provided on both sides of the notch, the lifting ears are fixedly mounted on the top wall of the working platform, a hand hoist is connected to the lifting ears, and the top end of the hand hoist is connected to the wet joint steel bars of the bridge deck.

[0010] The beneficial effects of the utility model are as follows: the cap beam sealing and anchoring safety operation platform can be quickly and safely erected on the bridge, thereby shortening the cap beam sealing and anchoring construction period and reducing the construction cost investment.

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described with reference to the accompanying drawings:

[0017] like Figures 1 to 4As shown, a bridge construction cap beam anchor sealing safety operation platform, including a work platform 1, a first guardrail net 2 is vertically installed on the top walls at both ends of the work platform 1, a second guardrail net 3 is vertically installed on the top wall of the outer end of the work platform 1, a notch 5 matching the end of the cap beam 4 is opened on the work platform 1, the work platform 1 is connected to the bridge body through a fixing component, a bridge construction cap beam anchor sealing safety operation platform, the fixing component includes a pair of longitudinal cantilever frames 6, the bottom ends of the longitudinal cantilever frames 6 are fixedly connected to the top wall of the work platform 1, and the longitudinal cantilever frames 6 are fixedly connected to the top wall of the work platform 1. The top of the arm 6 is fixedly connected to a transverse cantilever frame 7 that matches the top surface of the bridge. The inner end of the transverse cantilever frame 7 is fixedly connected to the wet joint steel bars of the bridge deck 8. Reinforcement ribs 9 are connected to the transverse cantilever frame 7. A connecting rod 10 is arranged in the notch 5. Both ends of the connecting rod 10 are fixedly connected to the working platform 1. Lifting ears 11 are provided on both sides of the notch 5. The lifting ears 11 are fixedly installed on the top wall of the working platform 1. A hand hoist 12 is connected to the lifting ear 11.

At this time, the hand chain hoist 12 is connected between the lifting ear 11 and the wet joint steel bar of the bridge deck 8, thereby improving the connection stability between the working platform 1 and the bridge and ensuring construction safety.

[0020] The first guardrail net 2 and the second guardrail net 3 prevent construction workers from falling from the working platform 1, thereby improving construction safety; the connecting rod 10 can further strengthen the structural strength of the working platform 1;

[0021] During construction, a ladder can be set up on the working platform 1 to facilitate the entry and exit of construction workers, and the supporting formwork used in the construction needs to be lifted by a crane;

[0022] After the construction is completed, it is only necessary to disconnect the transverse cantilever frame 7 welded to the wet joint steel bars of the bridge deck 8, and at the same time disconnect the hand hoist 12 from the wet joint steel bars of the bridge deck 8, so that the cap beam anchor sealing safety operation platform can be transported as a whole to the next construction site.
