Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The working platform of this embodiment is used for the secondary construction work between the adjacent hat beams 15, after the T-beam 14 is erected above the hat beams 15, the working platform is installed. Such as Figure 1~2 , the work platform of this embodiment includes a walking device slidingly connected to two adjacent T-beams 14 along the bridge direction, a connecting frame 2 located between two adjacent cap beams 15, and a platform fixed at the lower end of the connecting frame 2 3.

[0026] Such as Figure 1~2 As shown, the walking device is a gantry structure in which the two ends of the cross bridge are respectively erected on two adjacent T beams 14, including a support frame 1 arranged in the horizontal direction, and the two ends of the cross bridge of the support frame 1 are provided with columns 19. The s...

Abstract

The invention relates to the technical field of bridge construction structures, in particular to a work platform for secondary construction of a cap beam. The work platform comprises a traveling device connected onto two adjacent T-shaped beams along the direction of a bridge and a platform body positioned below the traveling device, wherein the traveling device is served as a portal-frame structure of which the two ends along the transverse direction of the bridge are respectively erected on the two adjacent T-shaped beams; rolling wheels are arranged at the lower end of the traveling device; a connecting frame is arranged between the platform body and the traveling device; the platform body is positioned below the front end of the traveling device; and through the connecting frame, the platform body is fixed on the traveling device to form a cantilever structure positioned in front of the traveling device. The work platform provided by the invention adopts the cantilever structure; through a counterweight arranged on the traveling device which can travel on a beam surface, the safety and the stability of the work platform can be ensured; and the work platform is simple in structure, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of bridge construction structures, in particular to an operation platform for secondary construction of a cap beam. Background technique [0002] With the rapid development of my country's economy, the demand for transportation is increasing rapidly, and the construction technology of bridge construction is also constantly improving. In the process of bridge engineering design, the combination system of large cantilever prestressed cap beam + prefabricated beam is more and more widely used in bridge construction due to its advantages of small structure occupation, convenient and fast construction, strong bearing capacity and beautiful appearance. [0003] The construction of the large cantilever prestressed hat beam is generally divided into two stages. The first stage is the pouring and prestressed construction of the hat beam. In this construction stage, part of the prestressed beam is stretched to ensure ...
