Problems solved by technology

my country is currently entering the peak period of infrastructure construction. At the same time, some highways and urban bridges were built earlier. Due to the limitations of people's understanding during the bridge construction period and the construction level at that time, the integration of roads and bridges with nature and the durability of bridges Insufficient consideration of rapid construction and transformation
At the same time, the original interchange standard is low. With the rapid growth of traffic flow and the upgrading of local road network in the later stage, the interchange of expressway must be expanded and reconstructed to alleviate the increasing traffic pressure.
[0003] For the reconstruction and expansion of urban bridges and expressways, bridge piers and cap beams are all concrete structures that need to be fabricated on site. Not only the construction period is long, but also the road will be broken, causing interference to the old traffic environment.

Embodiment Construction

[0020] See attached figure 1 , an assembled steel integrated bridge, including a steel pier column fixed on the cap or pile foundation, a cover beam 8 on the top of the steel pier column, and a main beam fixed on the cover beam 8, the key lies in: the The steel pier column structure includes 4 or 5 steel columns 1 and energy-dissipating components connecting the steel columns 1 , and each steel column 1 is formed by connecting multiple sections of steel columns with the help of connectors 3 . Using the connecting piece 3 to connect the multi-segment steel columns into the steel columns 1 of the required height can achieve the purpose of quickly connecting to form the pier columns of the required height.

[0021] See attached image 3 , the steel pier column is fixed to the cover beam 8 by means of the connection assembly 9, the structure of the connection assembly 9 includes a mounting plate 9-1 fixed to the steel pier column, a slide plate 9-2 arranged in the groove of the m...

Abstract

The invention discloses an assembled steel integrated bridge which comprises a steel pier stud fixed to a bearing platform or a pile foundation, a cover beam arranged at the top end of the steel pier stud, and a girder arranged on the cover beam. The assembled steel integrated bridge is characterized in that the structure of the steel pier stud comprises four or five steel stand columns and energy consumption components connecting the steel stand columns, and each steel stand column is formed by connecting a plurality of sections of steel stand column bodies through connecting pieces. The assembled steel integrated bridge has the advantages that all parts of the bridge are prefabricated and finished in a factory and assembled on the field, the construction speed is increased, the engineering quality is effectively ensured, and traffic interference on an existing route is relieved; a connecting assembly is used for connecting the pier stud and the cover beam, flexibility of the steel pier stud is utilized, a support and part of expansion joints can be removed, and the comfort of running of vehicles on the road surface is greatly improved; the whole bridge is of a steel structure, the dead weight of the bridge is greatly reduced, field lifting construction is convenient, the construction amount of a bridge pier is reduced, and the vertically-integral light weight of the structure of the bridge is achieved.

Description

technical field [0001] The invention belongs to the technical field of bridges, and is an assembled steel integrated bridge capable of rapid construction. Background technique [0002] With the sustained and rapid development of the national economy, the awareness of people-oriented security has been further enhanced, and the awareness of resisting natural disasters has also been further improved. my country is currently entering the peak period of infrastructure construction. At the same time, some highways and urban bridges were built earlier. Due to the limitations of people's understanding during the bridge construction period and the construction level at that time, the integration of roads and bridges with nature and the durability of bridges Insufficient consideration of aspects such as rapid construction and transformation. At the same time, the original interchange standard was low. Later, with the rapid growth of traffic flow and the upgrading of local road network...
