Problems solved by technology

Through a large number of engineering practices, it has been proved that although the bridge deck continuous device has created favorable conditions for the stability of driving, it has also reflected many problems during use. The phenomenon of concrete cracking at the continuous part is very common, which causes water seepage on the bridge deck and affects The durability of the cap beam concrete while the bridge's traffic levelness is compromised

Embodiment Construction

[0021] Refer to attached picture.

[0022] The invention introduces the arch structure in the bridge structure into the continuous part of the bridge deck, and disperses the stress concentration phenomenon of the concrete at this part. The bridge deck continuous device of the present invention includes an arch structure 1, and the two sides of the arch structure 1 are provided with mounting surfaces 11 for connecting with the bridge deck beam body. For vehicle loads, steel plates with a thickness of 9mm are used as the device material. Bolt holes 3 are provided on the mounting surface 11 . The upper part of the arched structure 1 is provided with I-beam-shaped ribs 2 at a certain distance along the width direction. On the one hand, the bearing capacity of the device can be improved, and on the other hand, the tensile stress borne by the concrete can be better dispersed.

[0023] Bridge deck continuous method of the present invention comprises the following steps:

Abstract

The invention firstly provides a bridge deck continuous device applied to a beam bridge, which comprises an arch structure. Both sides of the arch structure are provided with mounting surfaces connected with bridge deck beam bodies; and I-beam-shaped ribs are arranged above the arch structure along the width direction. The invention provides a bridge deck continuous method applied to the bridge deck continuous device, which comprises the following steps of: placing the bridge deck continuous device on concrete beam bodies at both sides of a bridge deck continuous position and paving asphalt felt between the mounting surfaces and contact positions of the concrete beam bodies; pouring bridge deck pavement concrete; and constructing kerfs at the joints of the bridge deck pavement concrete and both ends of a bridge deck continuous position. According to the device provided by the invention, the current situation that the current highway bridge deck continuous structure is easy to damage and is difficult to repair can be changed, the durability of the bridge deck continuous structure can be improved, the driving safety of the bridge can be ensured, the driving comfort of the highway bridge can be improved, the problem of water damage to a bridge pier and a bent cap, which is caused by improper treatment on the bridge deck continuous position, can be solved and the service life of the highway bridge can be effectively prolonged.

Description

technical field [0001] The invention relates to a bridge deck continuous device and a bridge deck continuous method of a girder bridge. Background technique [0002] With the progress of society and the rapid development of economy, the proportion of bridges on roads to the total length of road routes is getting higher and higher, even reaching 40% on some high-grade roads. Among all types of bridges, simply supported girder bridges are currently the most commonly used type of bridge due to their convenient construction and low cost, especially simply supported slab girder bridges, which have obvious advantages over other bridges in terms of construction and installation , The quality of girder slab pouring is also easy to be guaranteed, and it has an absolute advantage in small and medium bridges. Simply supported slab girder bridges are widely distributed in highways and urban roads. [0003] However, simply supported slab girder bridges also have some inherent shortcomin...
