Problems solved by technology

Due to the large number of main bars and stirrups in traditional concrete piers, the closely arranged steel bars will also cause difficulties in concrete pouring, which will have a negative impact on the construction quality and seismic behavior of the overall pier
The on-site construction operation method has considerable construction difficulty and danger, which in turn affects the construction period and cost

Embodiment 1

[0025] An assembled steel-concrete combined hollow bridge pier comprises an outer prefabricated concrete slab assembly, an inner prefabricated concrete slab assembly, a section steel assembly and structural steel bars.

[0026] The outer precast concrete slab assembly includes the outer precast concrete slab A 1 , the outer precast concrete slab B 2 , the embedded steel plate 3 , the steel bar sleeve 4 and the connecting steel bar 5 . The longitudinal ends of the outer precast concrete slab A 1 and the outer precast concrete slab B 2 are respectively provided with notches and tenons, and the outer precast concrete slab components are prefabricated vertically through the notches and tenons. The lateral end of the outer precast concrete slab A 1 is provided with a tenon and a pre-embedded steel plate 3 and a pre-embedded steel sleeve 4, and the lateral end of the outer precast concrete slab B 2 is provided with a notch and an embedded steel plate 3, A steel bar sleeve is welded ...

Embodiment 2

[0032] In this embodiment, the I-shaped steel 9 can be replaced by round steel bars, and a prefabricated steel-concrete composite hollow pier can be formed into a hollow square or hollow ring-shaped member by inner and outer prefabricated concrete slab assemblies. Other structures are the same as in Embodiment 1.

Abstract

The invention provides a fabricated profile steel reinforced concrete combined-type hollow pier. The fabricated profile steel reinforced concrete combined-type hollow pier comprises an outer-side prefabricated concrete slab assembly, an inner-side prefabricated concrete slab assembly, a profile steel assembly and constructional steel bars; the outer-side prefabricated concrete slab assembly and the inner-side prefabricated concrete slab assembly form a hollow annular structure, the profile steel assembly and the constructional steel bars are erected between the outer-side prefabricated concrete slab assembly and the inner-side prefabricated concrete slab assembly, and afterwards, concrete is poured. The outer-side prefabricated concrete slab assembly and the inner-side prefabricated concrete slab assembly are connected through a steel bar casing pipe and steel bars. According to the brand-new fabricated profile steel reinforced concrete combined-type hollow pier, the axial rigidity isimproved, the anti-seismic property is effectively improved, inner-side and outer-side prefabricated concrete slabs can serve as templates, templates do not need to be additionally arranged, all members can be prefabricated and subjected to segmental assembly in a construction site, the complexity of on-site construction is greatly reduced, the requirement for industrialized building is met, and the construction efficiency is improved.

Description

Technical field: [0001] The invention relates to the field of bridge substructures, in particular to an assembled steel-concrete combined hollow pier. Background technique: [0002] Bridge piers are one of the key structures in the bridge substructure. Due to the large number of main bars and stirrups of traditional concrete bridge piers, the closely arranged steel bars will also cause difficulties in concrete pouring, which will adversely affect the construction quality and seismic behavior of the overall bridge piers. The on-site construction operation method has considerable construction difficulty and danger, which in turn affects the construction period and cost. Invention content: [0003] Aiming at the deficiencies of the prior art, the invention provides an assembled steel-concrete composite hollow pier. The structure can meet the requirements of industrialized construction, and the construction speed is fast and the efficiency is high. It can improve the mechan...
