Embodiment Construction

[0032] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] Such as Figure 1-5 As shown, a pier-beam transition connection structure includes a pier column 1 and a cover beam 3. The pier column 1 includes a steel pipe 11 and concrete 12 inside the steel pipe 11. The cover beam 3 includes a cover beam top plate 31 and a cover beam 31. A beam bottom plate 32, the lower surface of the cover beam bottom plate 32 is connected with several anchor plates 4, and each of the anchor plates 4 is provided with several holes 5; the cover beam bottom plate 32 i...

Abstract

The invention relates to a pier and beam transitional connecting structure which comprises a pier column and a cover beam. The pier column comprises a steel pipe and concrete arranged in the steel pipe. The cover beam comprises a cover beam top board and a cover beam bottom board. The lower surface of the cover beam bottom board is connected with multiple anchor boards. Each anchor board is provided with multiple holes. The cover beam bottom board is fixed to the top of the steel pipe of the pier column. The anchor boards are embedded in the concrete in the steel pipe. By the adoption of the pier and beam transitional connecting structure, the multiple anchor boards are arranged on the cover beam bottom board of the cover beam, and each anchor board is provided with the multiple holes, so that when the cover beam and the pier column are connected with each other, the anchor boards are directly inserted in the steel pipe of the pier column, the anchor boards are embedded in the concrete in a sleeved manner when the concrete in the steel pipe is poured, the holes in the anchor boards serve as shearing force holes to interact with the concrete, and anchoring connection between the pier column and the cover beam is achieved. The pier and beam transitional connecting structure is simple, convenient to operate, short in construction period and more stable and effective in connection.

Description

technical field [0001] The invention relates to the field of composite structure bridges, in particular to a pier-beam transition connection structure. Background technique [0002] Due to the narrow terrain and site restrictions, the construction of modern mountainous highways generally adopts beam bridge structures. However, the existing simply supported concrete beams, due to the large weight of the beam body structure and high labor intensity, require a large amount of sand and gravel materials, and are poor in environmental protection, and the manufacturing process of the concrete beams requires vertical formwork for pouring. The period of the bridge is long, requiring health maintenance, and prone to quality defects; because the bridge piers erected in mountainous areas are generally relatively high, the construction difficulty of beam erection is increased. At the same time, geological disasters in mountainous areas are serious, and the bearing capacity and seismic pe...
