Embodiment Construction

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] like figure 1 As shown, the structure of a new type of bridge connecting plate includes the adjacent main girder 1, connecting plate 5 and connecting steel bar 6 located above the pier 8, the connecting plate 5 is cast-in-place reinforced concrete, the longitudinal section is wedge-shaped, and the main girder 1 It is connected with the connecting plate 5 through connecting steel bars 6, and the sliding layer 4 is filled between the connecting plate 5 and the main girder 1, the bridge deck 2 and the bridge deck pavement 3.

[0026] In this embodiment, the section of the main girder 1 adopts a box-shaped or T-shaped cross-section, which can be cast on site or prefabricated in a factory. The angle is between 30° and 45°, and a connecting steel bar 6 needs to be reserved for subsequent embedding into the cast-in-place connecting p...

Abstract

The invention provides a novel bridge connecting plate structure and construction method. The structure comprises main beams and connecting plates, the main beams are adjacently arranged, the connecting plates are arranged between the main beams, piers are arranged on the lower portion between the upper adjacent main beams, the adjacent main beams are connected through the connecting plates, the vertical cross section of each connecting plate is in a wedge shape, and connecting reinforcing steel bars are arranged in the connecting plates and extend into the adjacent main beams. According to the structure, displacement and corners of the main beams in a vertical bridge direction can be effectively absorbed, horizontal deformation between the main beams is converted into vertical deformationof the connecting plates, the deformation amount is greatly decreased, the horizontal deformation amount between the main beams is dispersed into two ends of each connecting plate, deformation requirements can be met, good waterproof performance is achieved, driving safety and smoothness is ensured, cracking of the connecting plates between the main beams is prevented, defects such as bumping atconnecting sections of the main beams is removed, the life cycle of a bridge can be prolonged, the passing capability of the bridge is improved, the structure has the advantages of simple structure, high universality, convenience in construction and the like, and the structure has great engineering significance and practical values.

Description

technical field [0001] The invention relates to a structure of a novel bridge connecting plate and a construction method thereof. Background technique [0002] During the actual operation of the bridge, due to the action of vehicle load, temperature and other external factors, the main girder is prone to longitudinal displacement and rotation angle, resulting in damage to the connecting device or telescopic device between the main girders. The damage of the connecting device or the telescopic device not only causes the car jumping phenomenon, which affects the ride comfort and safety of the vehicle, but also damages the connecting plate will cause different degrees of vibration. When it rains, the rainwater cannot be discharged in time, which will cause the connecting plate and the main beam to be damaged. Erosion by rainwater reduces the life cycle of the bridge and increases the maintenance cost of the bridge. The main reasons for the damage of the bridge connecting plate...
