Embodiment 1

[0059] See Example 1 Figure 13 As shown, this embodiment is a node construction operation platform where the profiled steel beam and the profiled steel column flange are connected, wherein the support plate 18.2 is an angle steel, the platform joist 18.3 is a channel steel, the steel pipe 18.6 is a bent steel pipe, and the cover plate joist 18.9 is The angle steel is welded with the platform joist 18.3, in which the support plate 2, that is, the upper flange of the angle steel and the upper flange of the profiled steel beam, are kept at the same height, and are welded on both sides of the profiled steel beam in two sections.

Embodiment 2

[0060] See Example 2 Figure 14 As shown in the figure, this embodiment is a node construction work platform where the profiled steel beam and the profiled steel column web are connected, wherein the support plate 18.2 is a steel plate, which can be replaced by the upper flange of the profiled steel beam in this embodiment, and the platform joist 18.3 is a groove Steel, the steel pipe of the steel pipe frame 18.6 is a one-inch pipe, and the cover plate joist 18.9 is welded with the angle steel and the platform joist 18.3.

[0061] Assemble the steel pipe frame at the construction site and lift it to the node with a crane; open the folding cover 18.7 during assembly, fix it with the hemp rope and the railing of the steel pipe frame, and the construction personnel will ascend from the reserved ladder to the platform; after the working platform is in place , the construction personnel fasten and fix the screw 18.4, and put down the folding cover 18.7; if the work platform needs t...

Abstract

The invention discloses a mountain stream river-crossing cable-stayed chain trestle and a hoisting method thereof. The mountain stream river-crossing cable-stayed chain trestle is in a four-frame and four-crossing structure and comprises a trestle steel frame and a steel frame stand column, wherein the trestle steel frame is formed by connecting four sections of steel from end to end; the junction of a first trestle steel frame and a second trestle steel frame is supported by the steel frame stand column; the junction of the second trestle steel frame and the third trestle steel frame is supported by a long steel frame stand column; the lower end of the first trestle steel frame is supported by a low-order pivot; the second trestle steel frame and the third trestle steel frame are positioned above a riverbed; the upper end of the third trestle steel frame is supported on a second high-order pivot; the lower end of the fourth trestle steel frame is supported by the high-order pivot; and the upper end of the fourth trestle steel frame is supported by a highest-order rolling support. According to the mountain stream river-crossing cable-stayed chain trestle, the technical problems that time and labor are wasted for manufacturing and splicing construction members in the air because the frame body of the mountain stream river-crossing cable-stayed chain trestle is erected in the air are solved.

Description

technical field [0001] The invention relates to a building trestle and a construction method thereof, in particular to a steel structure inclined zipper trestle and a hoisting method. Background technique [0002] The hoisting of the traditional mountain-river cross-river inclined zipper trestle adopts the method of erecting the frame body for construction and installation. This method of erecting the frame body makes the operator have to rise to a height of tens of meters for construction, and the components are fabricated at high altitude. And assembly, the construction period is long and labor-intensive. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a mountain stream cross-river inclined zipper trestle bridge and its hoisting method, which solves the technical problem of time-consuming, labor-intensive, labor-intensive, and labor-intensive, when the traditional inclined zipper trestle is erected at a high altitude. [0004] To ach...
