Embodiment Construction

[0011] As shown in Figures 1 and 2, the construction method of the suspension bridge tower beam without floor support of the present invention is that the tower beam relies on the load-bearing steel truss construction. As shown in Figure 1, the "corbel" is first installed on the tower column, then the prefabricated load-bearing steel truss is hoisted on the corbel, and then the construction platform is laid on the load-bearing steel truss, and the tower beam construction is carried out on the platform; Figure 2 As shown, the prefabricated load-bearing steel truss is hoisted and supported on the top of the tower column, and the "bottom-hanging working platform" is hung with the hanging connector, and the two ends of the "bottom-hanging working platform" are supported on the preset auxiliary cattle. On the legs to strengthen the support, the tower beam construction is carried out on the hanging working platform.

[0012] The above descriptions are only preferred embodiments of t...

Abstract

The invention discloses a construction method of non-floor stand of tower frame crossbeam of a suspension bridge. The method comprises the following steps of arranging a crossbeam construction platform on a bearing steel truss, wherein the bearing steel truss has two support manners. According to one support manner, the bearing steel truss is arranged on the bracket of a tower pillar and a deck-type crossbeam construction platform are arranged on the top of the bearing steel truss. According to the other support manner, the bearing steel truss is supported on the top of a tower frame, and a hanging crossbeam construction platform is hanged below the bearing steel truss by a hanger and arranged on the supports on both ends of an auxiliary bracket of the tower pillar.

Description

Technical field: [0001] The invention belongs to a new method for constructing a crossbeam of a tower frame of a suspension bridge. This method is an economical method with safety, short working hours and less material loss for the beam construction of high towers. Background technique: [0002] Suspension bridge is currently the bridge with the largest spanning capacity. With the rapid development of the national economy, the number of bridges spanning large rivers and straits is increasing day by day, so suspension bridges are often one of the solutions. [0003] Due to the increased span, the height of the tower, an important part of the suspension bridge, also increases correspondingly, generally exceeding 100 meters. In order to ensure the stability and strength of the tower, the tower column must be connected as a whole with one or more beams. As the bridge lane increases and the width increases, the span of the beam also increases accordingly. It can be seen that ...
