Embodiment Construction

[0032] Reinforced concrete arch bridge is a common form of bridge, which is widely used in crossing rivers and canyons. The arch ring of an arch bridge usually consists of the main arch ring and the belly arch ring. Considering the most unfavorable effects of dead load + cooling + live load of the belly arch foot, the maximum tensile stress at the upper edge of the belly arch foot may exceed the tensile stress limit of the concrete. The arch foot and the load-bearing area are most likely to cause cracking. Usually, hinges (incomplete hinges) are set at the arch foot of the abdominal arch, and the hinge is a concrete solid section. The top and bottom surfaces of the arch foot section are grooved and poured twice, and ordinary steel bars are used at the junction with the main arch. Construction For the main arch, pre-buried the reinforcement of the arch foot of the abdominal arch. After the construction of the bridge deck system, the support of the abdominal arch was removed, an...

Abstract

The invention provides a flexible hinge device for an arch bridge and the arch bridge and belongs to the field of bridge engineering. The flexible hinge device comprises at least one hinge unit and a connector, wherein at least one hinge unit comprises main bars and auxiliary bars; each main bar comprises two oppositely arranged installation grooves; the bottom of each installation groove is provided with one auxiliary bar; one end of each auxiliary bar is connected with the corresponding main bar and the other end extends towards a notch of the corresponding installation groove; and the adjacent main bars are connected through the connector. According to the flexible hinge device for the arch bridge, the construction quality of post-casting concrete of the combined segment of a main arch and web arch can be ensured, the additional stress generated in the construction process can be effectively released, local cracking of the concrete of the combined segment of the main arch and the web arch is effectively avoided, the casting quality is improved and the firmness and the security of a bridge body are improved.

Description

technical field [0001] The invention relates to the field of bridge engineering, in particular to an arch bridge flexible hinge device and an arch bridge. Background technique [0002] The Kwai-shaped arch bridge cancels the column or diagonal bracing, and instead uses the belly arch to span the main pier and directly connect the main arches on both sides. It is transparent and shaped like sunflower petals, so it gets its name. The sunflower-shaped arch bridge not only has the traditional heavy beauty of the arch bridge, but also shows the modern smart beauty because of its line shape, and has outstanding aesthetic effects. Because the pier top abdominal arch connects the main arches on both sides, it produces a horizontal thrust on the main arch, which makes the main arch bear the action of concentrated force, which increases the complexity of the structure, and the stress on the joint of the main abdominal arch is particularly complicated. [0003] Under the action of co...
