A method for installing anchor bolts in steel structures

Abstract

The invention discloses an installing method of a steel structure foundation screw bolt. The method is characterized in that a total station and a theodolite are used for performing axial unified location on installing molds arranged on each carrying table foundation screw bolt, so that an embedded screw bolt can be precisely and fast located. The installing method concretely comprises the following steps: manufacturing the installing molds; setting a measuring station; setting the installing molds; and locating and installing the embedded screw bolts. Compared with the prior art, the installing method has the advantages that the location and the installation can be precisely and fast performed; the construction efficiency is high; and the operation errors are reduced, so that the installation of the steel structure foundation screw bolt is standardized; and the requirement of construction specifications on foundation screw bolt installing precision can be met through enhancing the quality control via the normalized construction.

Description

technical field [0001] The invention relates to the technical field of building installation, in particular to a method for installing anchor bolts of a steel structure. Background technique [0002] At present, in the construction of steel structure factory buildings, the relative position between the foundation bolts adopts the steel plate positioning method. This method prefabricates a specific steel plate and pre-determines the positions of the bolts on it to drill holes, and the bolts are pre-threaded in the opening To determine the relative position between the bolts, the bolts are pre-tightened on the steel plate during construction and the steel plate is removed after the bolts are poured and fixed. However, when each group of anchor bolts of the cap is positioned on the general plane, the traditional method is basically adopted, that is, the axis is determined by the ink line and then the relative position of each group of bolts of the cap is adjusted manually. The...

Problems solved by technology

[0003] Although the existing technology has solved the positioning of the bolts on a cap foundation well, but in the construction of a factory building with a large scale and many caps, the steel plate positioning method needs to be manually adjusted and positioned on the caps one by one. , not only increases the workload, but also it is difficult to ensure sufficient accuracy for the positioning of each group of bolts on the general plane between the caps on each axis, and often fails to meet the specification requirements, and it takes more time to adjust the caps The relative position between each group of bolts is to ensure that the construction and installation requirements are met, resulting in a waste of time and human resources
