Problems solved by technology

However, the research on making prefabricated steel concrete and connecting prefabricated steel concrete with other prefabricated components is relatively rare, especially the research and application of connecting prefabricated steel concrete sections with prefabricated reinforced concrete sections as bridge piers has not yet been reported. The present invention is to design a prefabricated steel concrete and reinforced concrete assembled bridge pier

Embodiment 1

[0104] In this embodiment, the embedded part 1901 of the bottom section, the embedded part 1902 of the middle section and the embedded part 1903 of the top section are all steel pipe embedded parts, and the built-in section steel 18 of the first bottom section 1 is a built-in I-shaped steel, and the first bottom section Segment 1 , first middle segment 2 and first top segment 3 are square columns.

[0105] Such as Figure 1 to Figure 9 and Figure 56 to Figure 59 As shown, the prefabricated steel concrete and reinforced concrete assembled bridge pier includes a foundation 7, a first bottom segment 1, a first middle segment 2, a first top segment 3 and a cover beam 8, and the top of the foundation 7 passes through the bottom anchor bolt 9 is connected to one end of the first bottom segment 1, the other end of the first bottom segment 1 is connected to one end of the first intermediate segment 2 through an intermediate connecting anchor bolt 11, and the other end of the first i...

Embodiment 2

[0123] The difference between this embodiment and Embodiment 1 is that the first bottom segment 1 adopts built-in cross-shaped steel, such as Figure 10 with Figure 11 shown.

Embodiment 3

[0125] The difference between this embodiment and Embodiment 1 is that the embedded part 1902 of the first intermediate segment 2 adopts the embedded part of shaped steel. When the embedded part of shaped steel is used, the shaped steel 31 is made according to the design requirements, and along the A column of embedded part connectors 21 is welded longitudinally of the plate to form a shaped steel embedded part; Figure 12 with Figure 13 and Figure 51 to Figure 53 shown.

Abstract

Prefabricated steel reinforced concrete and reinforced concrete assembled bridge piers are provided with two connecting modes including bolt connection and connector connection, and each assembled bridge pier connected through bolts comprises a foundation, a first bottom section, a first middle section, a first top section and a bent cap. The assembled pier connected through the connectors comprises a foundation, a second bottom section, a second middle section, a second top section and a bent cap. The construction process of the prefabricated steel reinforced concrete and reinforced concreteassembled pier comprises the following steps that 1, components are manufactured, specifically, the first bottom section, the first middle section, the first top section and the bent cap are prefabricated, or the second bottom section, the second middle section, the second top section and the bent cap are prefabricated; 2, the components are mounted. The designed connection technology of the prefabricated sections and the foundation, the connection technology of the prefabricated sections and the connection technology of the prefabricated sections and the bent cap can guarantee that all the prefabricated parts are connected into a whole, and the structure is jointly stressed and deformed harmoniously.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, and in particular relates to prefabricated steel concrete and reinforced concrete assembled bridge piers and construction techniques. Background technique [0002] At present, most of the bridges built in my country are composed of cast-in-place reinforced concrete abutments, cast-in-place concrete piers, cast-in-place concrete bridge decks and precast concrete beams. Cast-in-place concrete construction is time-consuming and requires many on-site construction procedures that negatively affect traffic flow, safety in the work area and the environment, especially in complex construction environments, construction spaces, climatic conditions and environmental protection conditions Under the constraints of various factors, the development of bridge engineering industrialization technology has been further promoted, and prefabricated concrete assembly bridges have been produced. The prefab...
