Embodiment Construction
[0031] The following is further described in detail through specific implementation methods:
[0032] like Figure 1-7 The shown composite swivel support for bridge construction includes a circular support base plate 1, and the upper edge of the circular support base plate 1 is fixed with two or more circular side support templates stacked sequentially from bottom to top 5. The circular side support templates 5 are fixedly connected to the circular support base plate 1 through fixing bolts 6, and the circular side support formwork plates 5 are fixedly connected through fixing bolts 6. The upper surface of the circular support base plate 1 is fixed with Several limit guide posts 2 arranged in the circumferential direction, rigid springs 9 are respectively sleeved on the limit guide posts 2, limit support circular plates 3 are installed on the limit guide posts 2, and the upper ends of the limit guide posts 2 are provided with The snap-through holes 4 are respectively clipped a...

The invention discloses a combined swivel support for bridge construction. The upper edge of a circular support base plate is fixed with a plurality of circular side support templates stacked sequentially from bottom to top, and the circular side support templates are fixed by The bolts are fixedly connected to the circular support base plate, and the circular side support formwork is fixedly connected by fixing bolts. The upper surface of the circular support base plate is fixed with several limit guide pillars arranged along the circumference, and the limit guide pillars are respectively set There are rigid springs, and a limit support circular plate is installed on the limit guide post. The upper ends of the limit guide posts are respectively provided with snap-through holes, and the snap-through holes are respectively snapped and fixed with longitudinal steel bars arranged in the vertical direction. Several circular steel bars are welded and fixed sequentially and equidistantly between the steel bars. The combined swivel support is easy to install, high in stability, good in shock resistance and buffering, easy to disassemble after the formwork is used, and can be poured at different heights according to needs.
Description
technical field [0001] The invention relates to the field of bridge swivel supports, in particular to a combined swivel support for bridge construction. Background technique [0002] With the development of my country's society and economy, and the start of a new round of infrastructure construction, it is necessary to build more bridges across existing roads, railways, rivers, ditches, etc. The advantages of small impact and low safety risk have been widely used. [0003] The bridge swivel method can avoid the impact on the nearby transportation lines to the greatest extent, and it can also overcome the difficulties of erecting long-span bridges on rivers with high mountains and canyons, deep water and fast currents, or frequent ship navigation, especially in the construction of cities in heavy traffic areas. For flyover bridges and railway flyover bridges, the advantages of the bridge swivel method are more obvious. In recent years, bridge swivel construction technology h...
