Example Embodiment

[0037] figure 1It is a side view of the present invention. In this figure, the near-beam end of the half-beam 1 is linked to the anchor frame 3 through the rotating bracket 2, and the anchor frame 3 can be anchored to the steel beam 7 by means of welding, bolting, etc. The reinforcement 6 is consolidated with the concrete beam or abutment 8 . The half-beams on both sides of the bridge expansion joint protrude to the opposite side and are supported by the opposite half-beams. The specific support method will be described in detail later. The telescopic support system of the present invention does not have waterproof function, and its lower side imitates tooth plate seam and is provided with waterstop 4, plays the role of drainage and drainage. In this figure, the top surface of the half beam and the top surface of the rotating bracket are flush with the bridge deck. In order to make the figure concise and highlight the principle, the plug seam strip 9, positioning plate 14, ...

Abstract

The invention relates to a mutual support type bridge expansion device which not only can meet the needs of the expansion of the general bridge, but also can be adapted for large displacement and comprehensive composite deformation of skew bridges, curved bridges and ramp bridges. Half beams (when the displacement is large, center beams are additionally arranged) are distributed along the bridge direction, the beam far ends of the half beams of one side obtain support through the half beams of the other side and supply support for the beam far ends of the half beams of the other side at the same time, and expansion is realized. The center beams are mutually supported during the additional arrangement and expansion is realized to form an expansion support system. The beam near ends of the half beams are respectively linked with a beam body of a bridge through a linking system (rotating bracket) to meet the needs of longitudinal and lateral dislocation and sector change among the beam ends of the bridge. The expansion support system is combined with the linking system, the problem of vibration of a broken beam of a modular expansion device and the problem of tilt of gear ends of gear plate seams are eliminated, the rotation is flexible, and the adaptability is strong. The invention has the characteristics of long service life, stable traffic, convenient production, transportation, installation and maintenance, and the like.

Description

Technical field [0001] The invention relates to a bridge expansion device, which can not only meet the expansion and contraction requirements of general bridges, but also can especially adapt to the large displacement and all-round compound deformation of inclined bridges, curved bridges and slope bridges. Background technique [0002] There are three types of bridge expansion devices currently in use: [0003] First, the modular bridge expansion device. The ability to adapt to slope bridges and curved bridges is limited, and installation and maintenance are difficult; moreover, the vibration of the longitudinal beams arranged in the transverse direction of the bridge is difficult to eradicate when vehicles pass by, which will accelerate the damage of the device and shorten the service life. Although some improvements have been made after adding and subtracting noise panels, it is not uncommon for longitudinal beams to frequently bend along the direction of the bridge and c...
