Bridge bent cap supporting device without ground support and related supporting parts

Abstract

The invention provides a bridge bent cap supporting device without a ground support. The device comprises horizontal embedded tubes, horizontal supporting rods, connectors and vertical supporting parts, wherein the horizontal embedded tubes are horizontally embedded into bridge leg pieces, the horizontal supporting rods penetrate the horizontal embedded tubes, two ends of each horizontal supporting rod are bare and connected with two vertical supporting parts through two connectors respectively, and the vertical supporting parts are placed below transverse girders of a bridge and connected with the transverse girders of the bridge to support the transverse girders of the bridge. Preferably, the horizontal supporting rods are pins. More preferably, the pins are 30 chromium-manganese-titanium round-steel pins. The invention further provides related supporting parts. The bridge bent cap supporting device without the ground support not only ensures smooth bent cap construction, but also cannot hinder passage of vehicles on roads below bent cap construction positions, is ingenious in design, simple in structure and manufacture, convenient to construct, high in construction efficiency, low in cost and suitable for large-scale popularization and application, and saves time and labor.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to the technical field of bridge cover beam construction, in particular to a support device for a bridge cover beam without a floor support and related supports. Background technique [0002] In municipal engineering, there are more and more urban road reconstruction and expansion projects, and more and more elevated roads will be built on existing roads. Reconstruction and expansion projects are often carried out because the road is saturated with traffic, so closed Blocking traffic is not realistic. [0003] For example, the elevated project of a certain road in Shanghai is located on the road for reconstruction and expansion. The traffic police made it clear that the number of existing lanes must be guaranteed during the construction process of the project, and the "borrow one and return one" must be ensured. The passage of construction vehicles must also ensure th...
