The general method is to use prestressed concrete structure door-shaped pier beams and full hall brackets for construction. When steel structures are used, the tension supports supporting monorail traffic are directly welded to the steel components. However, the above-mentioned methods have obvious disadvantages. Full support has a great impact on ground road traffic and has potential safety hazards; secondly, since the tension support is a complex system, the installation accuracy requirements are relatively high, and it is difficult to meet the accuracy requirements by direct welding. Traffic lines pose safety hazards

Embodiment
[0023] Example: such as figure 1 As shown, the elevated section structure for straddle-type monorail in this embodiment is composed of a portal structure composed of pier columns 1 and cross beams 2, wherein the cross beam 2 is fixedly supported by the pier columns 1 located at both ends of the cross beam 2, and the top of the cross beam 2 is fixedly installed There are two tension supports 3, and each tension support 3 respectively supports a monorail track beam.
[0024] like Figure 9 , 10 As shown, the pier column 1 is a concrete pier column, and a vertically upward box-type embedded part 19 is arranged on the top of the column. There is a reserved short column 4 on the box-type embedded part 19, and the reserved short column 4 serves as a The connecting part of crossbeam 2, its periphery is also provided with connecting plate 17, has bolt hole 14 on the connecting plate 17; Figure 4-6 As shown, the crossbeam 2 is a prefabricated steel crossbeam, and the corresponding ...

The invention relates to the field of bridges, in particular to an elevated section structure used for straddle type single-track transportation. The elevated section structure is characterized in that piers are reinforced concrete piers, and the top of each pier is provided with a box type embedded part provided with a short prearranged column; transverse beams are prefabricated steel beams, installation holes are preformed in the installation positions, corresponding to the box type embedded parts, of lower wing boards at the two ends of each transverse beam respectively, preformed cavities are formed above the beam bodies of the transverse beams, and the installation holes are matched with the short prearranged columns in a sleeved mode and are connected in a matched mode so that the transverse beams can be fixedly connected with the piers. The elevated section structure has the advantages that construction quality of the steel transverse beams is guaranteed, the construction period is shortened, influence on ground transportation is reduced, and potential safety hazards caused by full-of-frame construction on a road are eliminated; the problem of anchoring installation of a single-track transportation pull support is solved, installation accuracy is high, and the supporting effect is good.
Description
technical field [0001] The invention relates to the field of bridges, in particular to an elevated section structure for a straddle monorail. Background technique [0002] The straddle-type monorail transit elevated line needs to be equipped with a door-shaped pier structure when the roadside is converted to each other in the middle of the road, the line spacing is large, and there are multiple lines. The general method is to use prestressed concrete structure door-shaped pier beams and full hall brackets for construction. When steel structures are used, the tension supports supporting monorail traffic are directly welded to the steel components. However, the above-mentioned methods have obvious disadvantages. Full support has a great impact on ground road traffic and has potential safety hazards; secondly, since the tension support is a complex system, the installation accuracy requirements are relatively high, and it is difficult to meet the accuracy requirements by direct...
