Integrated fixation and installation method for bolt

Abstract

The invention discloses an integrated fixation and installation method for a bolt, which comprises the following steps of: assembling U-steel with a bolt hole in pairs into a frame-shaped U-steel fixing mount; determining the central line of each edge and obviously marking the central line; mounting upright poles and cross bars of a rigid bracket on spot; welding the rigid bracket solidly; performing spot welding on a bonding strip preliminarily; horizontally placing the U-steel fixing mount on the cross bars, welding the U-steel fixing mount and the cross bars and fixing the two after the central line of the U-steel fixing mount is consistent with a pre-determined central line; allowing an embedded bolt to penetrate a bolt hole at the bottom; adjusting the height of the top end by using a nut for leveling the top end; bonding and fixing the whole body by using the bonding strip after the alignment is performed completely and the measurement and re-checking show no error. The integrated fixation and installation method for the bolt is simple, feasible, high in efficiency and reliable in construction equality, can be performed under a plurality of conditions and increase the working efficiency by at least four times, greatly saves cost and improves production efficiency.

Description

technical field [0001] The invention relates to a construction method in the construction process of an equipment foundation, and in particular relates to a construction method for integrally fixing and installing bolts. Background technique [0002] In the construction of metallurgical industry projects, with the control of the scale of the metallurgical industry by the state, the current low-volume engineering projects are restricted or controlled. As the scale of approved metallurgical projects is getting larger and larger, the required equipment and supporting facilities are becoming more and more complex, the corresponding construction technical requirements are becoming more and more precise, and the operating equipment and instruments are becoming more and more precise. Therefore, the installation accuracy requirements for equipment Also getting higher and higher. One of the manifestations is that the bolts on the base of engineering equipment increase accordingly, a...

Problems solved by technology

When the above method is used for construction, the accuracy of bolt installation is poor and the quality is not guaranteed

Surveying engineers are required to do a lot of coordinate and elevation work, the construction period is long, the labor intensity is high, and the labor cost is high

A large amount of steel is required to fix the bolts, and its strength and rigidity are not guaranteed. Concrete pouring can easily affect the vibration of the bolts, which can easily cause changes in the relative positions of the bolts and bring difficulties to equipment installation.
