Description
Technical Field
The utility model relates to a bridge engineering design technical field especially relates to a zero damage component of erecting steel shotcrete on bridge cap roof beam.
Background
In the existing engineering, the problem that a bridge is crossed with a road and a tunnel engineering often exists, and the situations that the road is excavated, the tunnel is excavated and the like under the existing bridge exist. Need erect interim steel shotcrete and consolidate to the bridge pile foundation of existing bridge under the condition that has the influence each other, reduce the influence of bridge horizontal force to the pile foundation in excavation process.
The conventional steel support is fixed on a bridge cap beam by adopting angle steel through an expansion screw to form a bracket structure for erecting a steel support flexible head, so that the safety and reliability of steel support erection are ensured. However, considering that the bridge is a century project, the existing bridge structure is necessarily affected by the form of driving the expansion bolts, and irrecoverable permanent damage can be caused.
Disclosure of Invention
The utility model aims at providing a set up the zero damage component of steel shotcrete on bridge cap roof beam according to above-mentioned prior art not enough, but utilize Z shaped steel plate pendant to transmit the interim steel shotcrete of bridge superstructure to the below and support to realize the zero damage installation of interim steel shotcrete.
The utility model discloses the purpose is realized accomplishing by following technical scheme:
the utility model provides a zero damage component of erectting steel shotcrete on bridge cap roof beam for erect interim steel shotcrete between the bridge cap roof beam which characterized in that: including Z shaped steel plate pendant, Z shaped steel plate pendant includes upper portion platform and lower part platform and connects the upper portion platform with connecting plate between the platform of lower part, the upper portion platform is fixed in the cap roof beam top, the laminating of connecting plate the cap roof beam side is arranged, the lower part platform supports interim steel shotcrete.
And a cushion block is arranged above the upper platform, the cushion block is positioned below the upper structure of the bridge, and the upper platform is fixed between the upper structure of the bridge and the cap beam of the bridge through the weight of the upper structure of the bridge.
The length of the upper platform is such that it is subject to the gravitational transfer provided by the weight of the bridge superstructure and supports the temporary steel support.
The length of the lower platform meets the requirement of supporting the end of the temporary steel support.
The utility model has the advantages that: the method is simple and reasonable, and can complete the installation and construction of the temporary steel support under the condition of zero damage; the provided temporary steel support can effectively reinforce the bridge pile foundation and reduce the influence of the horizontal force of the bridge on the pile foundation in the excavation process; the supporting effect on the temporary steel support is good, the stability is strong, and the safety factor is high.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the middle Z-shaped steel plate hanging piece of the present invention.
Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1, the symbols 1-8 in the figure are respectively expressed as: the bridge cap beam 1, the temporary steel support 2, the bridge superstructure 3, the cushion block 4, the Z-shaped steel plate hanging piece 5, the upper platform 6, the connecting plate 7 and the lower platform 8.
Example (b): as shown in fig. 1, in this embodiment, the zero-damage component for erecting the steel supports on the bridge cap beams is used for erecting the temporary steel supports 2 between the adjacent bridge cap beams 1, so that the bridge pile foundation can be effectively reinforced, and the influence of the horizontal force of the bridge on the pile foundation in the excavation process is reduced. As shown in fig. 1, bridge superstructures 3 are provided above the bridge cap 1, and these bridge superstructures 3 may be superstructures such as beams or bridge decks.
Specifically, the zero damage component in this embodiment is a Z-shaped steel plate hanger 5, and as shown in fig. 2, the Z-shaped steel plate hanger 5 includes three parts, i.e., an upper platform 6, a connecting plate 7 and a lower platform 8, wherein the connecting plate 7 connects the upper platform 6 and the lower platform 8, and the three parts form a Z shape in the horizontal bridge direction.
Referring to fig. 1, an upper platform 6 is arranged on the top surface of a bridge cap beam 1, a cushion block 4 is arranged above the upper platform, and a bridge superstructure 3 is arranged above the cushion block 4; under the influence of the weight of the bridge superstructure 3, its weight acts as a pressure on the Z-steel plate suspension tabs 5 via the spacer blocks 4, so that its upper platform 6 can be fixed between the bridge superstructure 3 and the bridge cap 1. The connecting plate 7 is arranged by being attached to the beam body of the bridge cap beam 1. The lower platform 8 extends outwards from one side of the bridge cap beam 1 and serves as a supporting position for the temporary steel supports 2, and the temporary steel supports 2 can be directly supported on the lower platform 8, so that the erection is completed. At this moment, because the upper portion platform 6 of Z shaped steel plate lacing film 5 is fixed through using bridge superstructure 3, therefore its rigidity, and then can effectively support interim steel shotcrete 2, meanwhile, because its whole of Z shaped steel plate lacing film 5 arranges completely on the outer wall surface of bridge cap roof beam 1, can not produce unrecoverable permanent destruction to bridge cap roof beam 1, alright realize that interim steel shotcrete 2's zero damage erects.
In the embodiment, in specific implementation: because the fixing of the Z-shaped steel plate hanging piece 5 is finished by utilizing the weight of the bridge upper structure 3, the length of the upper platform 6 and the lower platform 8 and the distance between the upper platform and the lower platform, namely the length of the connecting plate 7, are strictly calculated, and the bearing capacity transmitted by the Z-shaped steel plate hanging piece 5 can meet the supporting requirement of the temporary steel support 2.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims.
