Problems solved by technology

[0002] In municipal engineering, there are more and more urban road reconstruction and expansion projects, and more and more elevated roads will be built in the existing traffic roads. The reconstruction and expansion projects are often carried out because the road is saturated with traffic, so closed blocking traffic is not realistic

Embodiment Construction

[0032] In order to understand the technical content of the present invention more clearly, the following examples are given in detail.

[0033] See Figure 1-Figure 6 As shown, the bridge cap beam of the present invention has no floor support supporting device including a horizontal pre-embedded pipe fitting 1, a horizontal support bar 2, a connecting piece 3 and a vertical support 4, and the horizontal pre-embedded pipe fitting 1 is used for horizontal pre-embedded In the bridge column 10, the horizontal support rod 2 passes through the horizontal pre-embedded pipe 1 and the two ends of the horizontal support rod 2 are exposed, and the two ends of the horizontal support rod 2 pass through two The connecting piece 3 connects the two vertical supports 4, and the vertical support 4 is used to place under the bridge transverse main girder 20 and connect with the bridge transverse main girder 20 so as to support the bridge transverse main girder. Beam 20.

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...
