Site installation and debugging method of adjustable bridge steel support and matched steel support

Abstract

The invention relates to a site installation and debugging method of an adjustable bridge steel support, which solves the problems of danger brought by bridge foundation descent and poor tensile property and complex height-adjusting process of the bridge support. The method comprises the following steps of: accurately measuring the on-line height of the support by using a height measuring device; selecting the off-line presetting of the adjustable bridge steel support to set the height of the support according to the measured height; making an upper support plate of the steel support meet the requirements of engineering design by means of an adjustable stepless height-adjusting mechanism of the steel support; after installing the bridge, laying a railway track and loading actual measurements, making the upper support plate of the steel support meet the dynamic requirements of engineering design by means of the adjustable mechanism of the steel support; and adjustably positioning the steel support by means of a locking mechanism. The invention also relates to an adjustable curved steel support matched with the method. The invention has simple method, easy implementation and stepless height-adjusting function, the transmission force of height adjustment is relatively smooth and steady, and large loads or vibration can be supported.

Description

technical field [0001] The invention belongs to the field of bridge support installation and adjustment, and in particular relates to a method for on-site debugging and installation of an adjustable bridge steel support and a steel support for height adjustment using the method. Background technique [0002] Usually, a support is set in a bridge structure or a building structure, and its function is to reliably transmit the reaction force and deformation of the upper structure, that is, displacement and rotation angle, to the lower structure, and reduce and eliminate the influence of the deformation of the upper structure on the lower structure . Under normal circumstances, it is required to make a bearing capable of bearing vertical bearing capacity, rotation performance and horizontal displacement performance. Specifically, it is divided into three types: fixed support, one-way support and multi-directional support. In most cases, the support has the above functions to me...
