Ramp bridge scaffold support with overlapped arc-shaped steel plates

Abstract

The invention discloses a ramp bridge scaffold support with overlapped arc-shaped steel plates, and relates to the technical field of bridge construction. The ramp bridge scaffold support comprises aplurality of horizontally-overlapped steel plate layers. Each steel plate layer is provided with a top layer. An upward arc surface is arranged on the surface of each top layer and has an angle r, andr is larger than 30 degrees and smaller than 60 degrees. The arc-shaped steel plates with a certain radius are prepared and placed on the top of a support body and overlapped with other steel platesto form the temporary support.

Description

technical field

[0001] The invention relates to the technical field of bridge construction, in particular to an arc-shaped steel plate superimposed support of a slope bridge scaffolding. Background technique

[0002] In the existing technology, the scaffolding method is often used in the cast-in-place construction of bridges. When the bridge has a longitudinal slope design or is located on a vertical curve, the elevation of the bottom of the beam is constantly changing. In traditional construction, it can usually be used on the beam The wedge-shaped steel plate is installed at the bottom to realize the slope adjustment and load transmission between the beam bottom and the bracket. When using the wedge-shaped steel plate, the thickness of the wedge-shaped steel plate needs to be adjusted continuously according to the vertical curve of the bridge slope. If the thickness of the wedge-shaped steel plate is not set properly, it will cause a slope. The beam plate will produce a ce...

Embodiment 1

[0026] Embodiment one, such as figure 1 The shown arc-shaped steel plate superimposed support for slope bridge scaffolding includes several horizontally stacked steel plate layers 1, the steel plate layer 1 has a top layer 11, and the surface of the top layer 11 has an upward arc surface 12, and the arc surface 12 has a 30° The angle r. The horizontal area of ​​the steel plate layer 1 is arranged from large to small from bottom to top, and the horizontal area of ​​the steel plate layer 1 is 1:3 / 4:1 / 2:1 / 4 from bottom to top. Freely placed between steel plate layers 1. The top layer 11 adopts high-strength wear-resistant steel materials such as No. 45 steel, and the steel plate layer 1 other than the top layer 11 is made of common Q235 steel plates. This device is used in the construction of cast-in-place tie girder scaffolding. The bridge is located on the vertical curve. This device solves the problem of uneven force on the support of the beam bottom and the resulting stabil...
