Embodiment 1

[0047] see figure 1 As shown, the embodiment of the present application provides a bolt information management method, which includes the following steps:

[0048] 100: Obtain the initial torque coefficient K and fastening axial force ratio η of each batch of bolts;

[0049] The information management method of Example 1 of the present application can be used for high-strength bolts and ordinary bolts. After a batch of bolts is produced, the torque test and tightening torque test are first performed on the batch of bolts in the laboratory to obtain the initial value of the batch of bolts. The torque coefficient K and the fastening axial force ratio η are input into the bolt information management system to realize the summary and statistics of the basic information of the bolts, and the bolts are stored in the warehouse for future use.

[0050] 101: store the basic information, K and η of each batch of bolts, the basic information includes the diameter d of the bolt and the tar...

Embodiment 2

[0096] Embodiment 2 of the present application provides an information management system for bolts, which includes a first module, a second module, and a third module; wherein,

[0097] The first module is used to: store the basic information of each batch of bolts, and the initial torque coefficient K and fastening axial force ratio η of each batch of bolts obtained by the second module, the basic information includes the diameter d of the bolts and the target axial force P 目标轴力 ;

[0098] The operator inputs the initial torque coefficient K obtained through the torque test and the fastening axial force ratio η obtained from the fastening torque test into the information management system, and inputs the basic information of each batch of bolts into the information management system , the first module stores the data of bolts from production to screwing, which is convenient for later calculation.

[0099] The second module is used to: obtain the initial torque coefficient K...

Abstract

The invention relates to an informatization management method and system for bolts, and relates to the technical field of bridge construction, and the method comprises the following steps: obtaining an initial torque coefficient K and a fastening axial force ratio eta of each batch of bolts; storing the basic information, K and eta of each batch of bolts, wherein the basic information comprises the diameter d of the bolt and the target axial force of the target axial force P; according to the construction requirements, calling K of the bolts of the target batch, and correcting K to obtain a corrected torque coefficient K; calling d and P target axial forces and eta of the bolts of the target batch, and calculating final screwing torque T final screwing and checking torque T checking of the bolts in combination with K correction; according to the T inspection, obtaining a qualified screwing range, and generating a screwing guidance notice for guiding an operator to screw a bolt in combination with the T final screwing; obtaining the actual torque T < actual > of the bolt after the bolt is finally screwed on the basis of the screwing instruction notice, and judging whether the T < actual > is within the qualified screwing range or not; if yes, judging that the screwing is qualified; and if not, judging that the screwing is unqualified.

Description

technical field [0001] The present application relates to the technical field of bridge construction, in particular to an information management method and system for bolts. Background technique [0002] In recent years, with the popularization and application of steel structures and the development of bridge construction, more and more bridge connections are bolted, that is, assembled with high-strength bolts. [0003] Under the existing high-strength bolt construction conditions, high-strength bolts from entering the site to tightening, and then passing the inspection involve basic information, process data, and tightening position information of high-strength bolts. There are many technical processes and complicated data. Most of them are carried out by manual recording and manual calculation, which is inefficient and requires a lot of labor input. Contents of the invention [0004] The embodiment of the present application provides a bolt information management method...
