Method for mounting steel-structure module in place

Abstract

The invention provides a method for mounting a steel-structure module in place. The method for mounting the steel-structure module in place comprises the steps that foundation bolts are mounted in place; a concrete foundation is poured; steel column base mortar lumps are arranged on the foundation; guiding devices and a horizontal jacking deviation correction device used for leveling a base are manufactured, and the guiding devices are arranged at the tops of the foundation bolts in a sleeving mode; bolt holes are formed in the base; steel columns are welded on the base; the steel columns and a steel-structure beam are assembled into a steel-structure frame in a prefabrication factory, technological pipelines are mounted in the frame, and thus the steel-structure module is formed; the steel-structure module is transported to a mounting position through a transport vehicle; and the relative positions between the bolt holes and the foundation bolts are checked, the module is lowered slowly through a transport vehicle hydraulic system, whether upper openings of the guiding devices are within the ranges of the bolt holes or not is checked in real time, and the guiding devices are dismounted after the steel-structure module is mounted in place accurately. By adoption of the method for mounting the steel-structure module in place, chambering of the bolt holes in the steel column base on a field can be avoided, and thus the construction quality is ensured; and slight horizontal movement can be achieved through the guiding devices, the self weight of the module and the horizontal jacking deviation correction device, and thus the purpose of mounting the module in place rapidly and accurately is achieved.

Description

technical field [0001] The invention relates to the field of installation of steel structure modules, in particular to a method for installing steel structure modules in place. Background technique [0002] In engineering practice, with the vigorous advancement of the "four modernizations" with modularization as the main content, the pipe gallery structure and process modular construction will gradually increase its market share. The current steel structure modular construction mainly has the following two positioning methods: first, the base of the steel structure module is installed and fixed on the concrete foundation, and after the steel structure module is transported in place, the steel column and the base are welded and fixed. This scheme is more convenient to install the steel structure module in place, but the welding work on site is large, and the welding quality is not easy to control; the second is to assemble the steel column, steel structure beam, and base into...

The current steel structure modular construction mainly has the following two positioning methods: first, the base of the steel structure module is installed and fixed on the concrete foundation, and after the steel structure module is transported in place, the steel column and the base are welded and fixed. This scheme is more convenient to install the steel structure module in place, but the welding work on site is large, and the welding quality is not easy to control; the second is to assemble the steel column, steel structure beam, and base into a steel structure frame in advance in the prefabrication plant, and in the frame according to Design and install the fixed process pipeline to form a steel structure module, and then install the module in place as a whole, and only rely on the horizontal movement of the module transport vehicle to achieve accurate positioning during the positioning process, although this solution can avoid on-site inspection of the bolt holes of the steel column base Reaming is carried out to effectively guarantee the construction quality, but due to the deformation and error of the steel structure module prefabrication process and the deviation of the foundation embedded anchor bolts, the gap between the bolt holes and the anchor bolts is limited, and the horizontal direction of the module transport vehicle, especially the vertical Due to the limited range of slight movement in the direction of the vehicle body, it is difficult to install the modules of this solution in place, and it also increases the risk of damage to the bolts during the installation process
