Problems solved by technology

However, on the one hand, due to the large number of gusset plates on the steel truss, and the distribution of positions is different, it is necessary to repeatedly hang and remove temporary hangers during the bolt welding process, which is cumbersome and time-consuming. On the other hand, temporary hangers are usually The truss structure assembled up and down has a narrow operating space and is inconvenient for construction operations, resulting in low operating efficiency, poor stability, and high safety risks

Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0031] see figure 1 and figure 2 As shown, the embodiment of the present invention provides a telescopic construction platform, which includes a track 1, a frame body 2 and four telescopic assemblies 3, and each telescopic assembly 3 is provided with a working platform 31.

[0032] The track 1 includes two guide rails 10 arranged side by side, and the frame body 2 is slidably arranged on the two guide rails 10 , and the frame body 2 includes a first bracket 20 and a second bracket 21 distributed up and down. The frame body 2 is a truss structure, which is welded by steel pipes and assembled in multiple stages. On the basis of ensuring a firm structure, it is light in weight, making the structure lighter and easier to use.

[0033] Specifically, the telescopic assembly 3 includes a telescopic frame 30 arranged horizontally, and a work platfo...

Abstract

The invention discloses a telescoping construction platform and relates to the field of bridge construction. The telescoping construction platform includes a pathway, a frame body and at least one telescoping assembly. The pathway includes at least two guiding rails arranged side by side. Frame body sliding sets are arranged on the two guiding rails. The frame body includes a first supporting frame and a second supporting frame which are distributed up and down. Each telescoping assembly includes a horizontally arranged telescoping frame and a working platform arranged on the telescoping frame. A telescoping frame sliding set is arranged on the frame body. The telescoping frame can move horizontally in the direction perpendicular to the guiding rails. According to the telescoping construction platform, construction efficiency is high, the construction scope is wide, manpower and material resources are greatly saved, the operation space is large, and construction operation is advantageous.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a retractable construction platform and a bridge equipped with the construction platform. Background technique [0002] Steel truss bridges are a common structural form of heavy-duty bridges. Especially in the design of double-deck bridges, they have the characteristics of light weight, high rigidity, material saving and cost reduction. High-strength bolts are often used for the connection between members Connections, gusset plates are numerous and scattered. [0003] At present, in the erection of double-deck bridges, in order to bolt and weld the steel trusses of the upper bridge, a temporary hanger is usually erected on the lower bridge, which is used as a bolting and welding construction platform. However, on the one hand, due to the large number of gusset plates on the steel truss, and the distribution of positions is different, it is necessary to repeatedly hang and remo...
