Embodiment

[0030] A vibration-damping locking type anti-box girder falling beam device, combined with figure 1 , image 3 , Figure 4 , Figure 5 , Figure 6 , including the first steel column 18 and the second steel column 19 that are embedded horizontally through the first box girder 3 and the second box girder 4, and also include the An incomplete spherical through groove that runs through one side and along the width direction. A connecting post 14 is inserted into the two spherical through slots, and there are accommodation cavities between the left and right sides of the connecting post 14 and the two spherical through slots, and a shock absorber with a wall thickness of 5mm is inserted in the accommodating cavity. The column 15, the interior of the vibration-damping column 15 is hollow, and the vibration-damping column 15 is filled with a number of vibration-damping balls 20. The vibration-damping ball 20 includes two hemispherical hemispherical beads 21 and an annular soft be...

Abstract

The invention relates to the field of bridge engineering, and particularly discloses a vibration reduction locking type box girder falling prevention device. The device comprises a first steel columnand a second steel column which are embedded in a first box girder and a second box girder in a penetrating mode, and the two ends of the first steel column and the two ends of the second steel columnare fixedly connected through connecting plates. Incomplete spherical through grooves are formed in the opposite ends of the first box girder and the second box girder in the width direction in a penetrating mode, a connecting insertion column is inserted into the two spherical through grooves, containing cavities are reserved between the two ends of the connecting insertion column and the two spherical through grooves, vibration reduction columns are inserted into the containing cavities, the vibration reduction columns are hollow, the vibration reduction columns are filled with a pluralityof vibration reduction balls, and first springs are arranged in the vibration reduction balls. The invention aims to solve the technical problem of girder falling caused by displacement of the box girders.

Description

technical field [0001] The invention relates to the field of bridge engineering, and specifically discloses a vibration-damping and locking type anti-falling girder device for box girders. Background technique [0002] The box girder is hollow inside, with flanges on both sides of the upper part, and can be divided into single box and multi box. The box girder of reinforced concrete structure is divided into prefabricated box girder and cast-in-place box girder. The prefabricated box girder combined with the bridge erecting machine can be erected after the completion of the substructure, which can speed up the progress of the project and save the construction period; the cast-in-place box girder is mostly used for large continuous bridges. The box girder is connected to the grounded pier below through the supports on both sides. If the support is damaged under special loads such as earthquakes, the box girder will undergo lateral or longitudinal displacement, which will cau...
