Abstract
The invention belongs to the field of bridge engineering, and particularly relates to a steel arch bridge steel structure lower string construction technique for a steel arch bridge. The technique is characterized in that: built-in fitting parts are arranged on corresponding positions where steel strands connect piers; and after a steel arch bridge body and a pier structure are constructed, steel strands with a suitable length are selected to connect two sides of the steel arch bridge piers, and then construction of the steel arch bridge is completed. The technique can rapidly complete construction of a steel arch bridge lower string, and achieve completion of the whole steel arch bridge, ensure improved the weight capacity of the steel arch bridge, and prolong the service life.
Description
Technical field
The invention belongs to science of bridge building field, be particularly applied in steel bow bridge steel construction lower edge construction technology。
Background technology
Steel bow bridge realizes the function of bridge with the form of bow, steel construction is adopted to undertake the driving vehicle effect to the power that the body of a bridge produces, for strengthening steel bow bridge weight capacity and extending the service life of steel bow bridge, the bottom bending bridge at steel is provided with lower beam string structure, share the stress of steel bow bridge bridge pier, the present invention provides steel bow bridge steel construction lower edge construction technology, can realize the installation of lower beam string structure rapidly, save time and cost。
Summary of the invention
It is an object of the present invention to provide steel bow bridge steel construction lower edge construction technology, be mainly used for steel bow bridge, by being rapidly completed the construction of steel bow bridge lower edge, it is achieved steel bow bridge entirety is completed, guarantee that steel bow bridge weight capacity promotes to some extent simultaneously, and service life extends to some extent。
The technical solution used in the present invention is: built-in fitting is left in the corresponding position being connected bridge pier by steel strand wires, after the steel bow bridge body of a bridge and bridge pier structure have been constructed, selects the steel strand wires of appropriate length to connect steel bow bridge bridge pier both sides, completes the construction of steel bow bridge。
Described steel strand wires connect the relevant position of bridge pier, refer to according to steel bend bridge across footpath, the position of steel strand wires determined of the factor such as width and the load-bearing upper limit。
Described built-in fitting, namely connects the component of steel strand wires and bridge pier structure。
The steel strand wires of described appropriate length, namely consider the length after force analysis and cost optimization。
The present invention is applicable to steel bow bridge, built-in fitting is left by connecting steel strand wires corresponding position at bridge pier, after the steel bow bridge body of a bridge and bridge pier structure have been constructed, the steel strand wires selecting appropriate length connect steel bow bridge bridge pier both sides, complete the construction of steel bow bridge, the construction of lower edge can be quickly finished, the weight capacity of steel bow bridge can be improved again, extend the service life of steel bow bridge。

Detailed description of the invention
Describe the present invention below with reference to accompanying drawing。But embodiments of the present invention are not limited to that。
Quantity and the length of steel strand wires is determined according to steel bow bridge force analysis and cost optimization, Prefabrication steel bow bridge bridge floor 1 and the bridge pier 2 with bridge pier built-in fitting 4 in workshop, the quantity of bridge pier built-in fitting 4 is consistent with the quantity of steel strand wires 3, to be produced complete after be transported to construction site, assembly and connection steel bow bridge bridge floor 1 and bridge pier 2, then one end of steel strand wires 3 is connected on the bridge pier built-in fitting 4 of bridge pier 2 side, the opposite side of steel strand wires 3 is connected on the bridge pier built-in fitting 4 of bridge pier 2 opposite side, completes the construction of steel bow bridge。
The present invention is not limited to above-mentioned embodiment, and anyone can obtain the method for steel bow bridge lower edge construction under the enlightenment of the present invention。All equalizations done according to the present patent application the scope of the claims change and modify, and all should belong to the covering scope of the present invention。
